Conventional Infertility Treatments "Useless"

Conventional Infertility Treatments "Useless" Even As Fertility Rates Plummet for Mainstream Toxic Consumers

(NaturalNews) Research on conventional infertility treatments that monitored the results of 580 couples found such treatments to have absolutely no benefit. Conducted in Scotland, the research involved five hospitals providing artificial insemination and the prescription drug clomid -- a drug commonly used for treating infertility in the United States, Canada and other western nations.
The research reveals that couples attempting to conceive naturally experienced a 17% success rate (becoming pregnant and giving birth to a healthy baby) while those on the clomid drug actually had a lower rate of success: 14%. Even worse, from 10 to 20 percent of women on the drug experienced side effects that included abdominal pain, bloating, nausea and headaches. Continue Reading >>

Health Tip: Feeding Your Baby

(HealthDay News) -- It's important for new parents to understand what and how often your baby needs to eat, and how that schedule should change as your baby matures.

The U.S. National Library of Medicine offers these guidelines to help plan your baby's feeding:

  • Babies who breast-feed typically need to be fed once every one to three hours.

  • Babies on a diet of formula need to be fed every two to four hours, as formula takes longer to digest.

  • You should never give a baby younger than 1 cow's milk, since it is difficult for an infant to digest.

  • Don't attempt to give baby any solid food until at least 4 months of age, preferably 6 months of age.

  • Begin introducing solid foods between 6 months and 12 months of age, starting with pureed or mashed foods, and graduating to more solid foods.

  • Introduce new foods one at a time, and monitor closely for signs of allergic reaction. New foods should be introduced only when an infant is hungry.

I Love Peanuts, but They Could Kill My Son

By Sean Kelley

I’m a peanut junkie. I love PB&Js, peanut butter pies, peanuts in Coca Cola bottles (a Southern treat that is just what it sounds like), and peanut brittle. I’ve been seen eating peanut butter straight out of the jar—with a spoon when handy and with fingers when not. When I introduced my wife, Patti, to the 105-year-old woman who helped raise me as my nanny, she offered only one piece of advice to her: “Don’t you run out of peanut butter.”

Well, the days of the endless supply are over. My one food peccadillo can kill my son. We just learned that Graeme is deathly allergic to peanuts.

Our 18-month-old began having problems the minute he was exposed to people food. Baby food was fine, milk was fine, but certain highly processed foods would make him react. At first it was minor: A few red splotches around his neck or flushed cheeks. Read More

Health Tip: Heal Baby's Diaper Rash

(HealthDay News) - Diaper rash is a red, bumpy breakout that occurs when a baby has worn a dirty diaper, and the skin becomes irritated.

Here are suggestions on how to prevent and treat the condition, courtesy of the U.S. National Library of Medicine:
  • Change diapers frequently. Don't allow the infant to wear a wet or soiled diaper for long.
  • Try to leave the infant without a diaper for a while, so that the air can help dry the area.
  • Wash the baby's bottom with plain warm water. Avoid baby wipes if they tend to cause irritation.
  • Try a cream or ointment to soothe and protect the skin, but avoid irritating powders.
  • If the rash doesn't heal in a reasonable amount of time, have the infant see a doctor.

Health Tip: Break the Habit of Thumb Sucking

(HealthDay News) -- Babies and young children satisfy the natural reflex to suck by sucking on pacifiers, fingers or thumbs. However, thumb sucking can affect the alignment of permanent teeth as they grow in.

While most children will stop the habit on their own between the ages of 2 and 4, others may need help. Here are suggestions to help your child stop sucking his or her thumb, courtesy of the American Dental Association:
  • Don't scold the child when they do suck the thumb, but praise him or her when they aren't doing it.
  • If your child sucks the thumb when anxious, upset or frightened, try to resolve the root of the anxiety.
  • For a child old enough to understand, let him or her decide on how to break the habit.
  • Have your child talk to the doctor or dentist about the damage that can be done by continuing to suck the thumb.
  • Try wrapping the thumb in a bandage, a sock, or coating it with a bitter-tasting solution.

Food for the Aging Mind

Agricultural Research
08-27-07
Originally Published:20070801.

Scientists know that certain nutrients and other key chemical compounds are essential to human brain function. Serious deficiencies in some of these, such as vitamin B12 and iron, can lead to impaired cognitive function due to neurological, or nerve fiber, complications.

Cognition can be defined as the ability to use simple-to-complex information to meet the challenges of daily living.

So, could careful attention to diet help protect the aging brain from problems with nerve cell signals involved in memory and cognition? A clear-cut answer could greatly affect the 77 million baby boomers who are now facing retirement. Their independence, quality of life, and even economic status will largely be defined by their ability to traffic information signals as they age.

In researching the nutrition-brain connection, new technologies are being used, such as those that take images of the brain or actually count individual brain cells. Behavioral tests that measure motor and cognitive skills-or lack thereof-are also providing insights. Yet the science of nutrition and brain function is relatively new and evolving.

Agricultural Research Service scientists at several locations nationwide are contributing to a growing body of research that explores the effect of diet and nutrition on the brain and its function across the lifespan.

Boosting Neuronal Function
The brain's billions of neurons "talk" to one another through chemical neurotransmitters that convey signals through neural pathways. These chemical transporters- which include norepinephrine, serotonin, and dopamine-are key to signal movement.

Although people naturally lose brain cells throughout their lives, the process of neuronal death does not necessarily accelerate with aging. "There is a lot of individual difference," says ARS neuroscientist James Joseph. "Loss of mental agility may be less due to loss of brain cells than to the cells' failure to communicate effectively."

Joseph heads the Neuroscience Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University in Boston. There, researchers are looking at the beneficial effects of certain dietary plant compounds to learn how they affect brain function.

"Vitamins and minerals in plant foods provide protective antioxidants," says Joseph. "But fruits, vegetables, nuts, seeds, and grains contain thousands of other types of compounds that contribute significantly to the overall dietary intake of antioxidants.

"A partial measure of the antioxidant effect is called 'ORAC,' for Oxygen Radical Absorbance Capacity. ORAC scores are now showing up in charts and on some food and beverage packages. They may be helpful in choosing foods to include in your diet."

Perhaps there is no better place in which to gauge the power of antioxidants than between the minute connections of the nerve cells.

Bucking Long-Held Dogma
Eight years ago, Joseph and colleagues began publishing a series of studies, done in rodents, that shed light on the relationship between various diets and the mechanisms behind cognitive losses in specific neighborhoods of the aging brain.

Many in the series are groundbreaking in that they challenge the long-accepted belief that the central nervous system, which includes the brain, is not capable of regenerating itself. Other published studies in the series echo similar findings based on primate and human brain research at the Salk Institute for Biological Studies, San Diego, California. Scientists there, using new technologies, disputed the notion that the brain does not make new neurons-a process called "neurogenesis"-into old age: It does, but at a much slower rate.

One of the first of Joseph's studies, published in the Journal of Neuroscience, showed a protective effect of consuming antioxidants. Study rats were fed-from adulthood to middle age-vitamin E, strawberry extracts, or spinach extracts, all with similar ORAC values. Animals receiving the high-antioxidant diets did not experience the age-related cognitive performance losses seen in control rats fed standard chow.

A later study, also published in the Journal of Neuroscience, showed a reversal of functional loss among rats on special diets. Each of three groups of rats, equivalent in age to 63-year-old humans, was fed a different high-antioxidant extract. A control group was fed standard chow.

After 8 weeks-equivalent to about 10 years in humans-the rats' performance levels were measured.

The rats fed the spinach, strawberry, or blueberry extracts effectively reversed age-related deficits in neuronal and cognitive function. In addition, the blueberryfed group far outperformed their peers while traversing a rotating rod to test balance and coordination.

"Despite their status as 'senior citizens,' those rats showed remarkable stamina on neuromotor function tests," says psychologist and coauthor Barbara Shukitt-Hale, also with the Neuroscience Laboratory.

Examination of the brain tissue of those blueberry-fed rats showed much higher levels of dopamine than were found in the other groups. Dopamine has many functions within the brain. In particular, it can affect the way the brain controls movements.

"We suspected that the combined antioxidant potency of compounds in blueberry extract may have reduced inflammatory compounds in the brains of these older animals," says Joseph.

"Inflammation ordinarily contributes to neuronal and behavioral shortfalls during aging."
Tests have since shown that blueberry compounds cross the blood-brain barrier and localize in rodent brain tissue.

Hard News: Brain Plaques
Later, the lab's researchers published an Alzheimer's disease model study in Nutritional Neuroscience. They studied mice that carried a genetic mutation for promoting increased amounts of amyloid beta, a protein fragment found within the telltale neuritic plaque, or "hardening of the brain," seen in Alzheimer's disease.

Although the exact cause of Alzheimer's is not completely understood, experts have recently identified one mechanism involving the insufficient breakdown and recycling of amyloid protein in the brain. That mechanism is both genetic and physiological. In those individuals, normally harmless amyloid protein turns into fragments of amyloid beta, which build up as plaque in the brain rather than being escorted into cellular recycling. That action leads to cell death and weakened neuronal communication.

In the mouse study, beginning at age 4 months-early adulthood-half the brainplaqued group was fed a diet that included blueberry extract for 8 months. The other half was fed standard rat chow and so was a control group of mice that didn't carry the amyloid-plaque mutation.

At 12 months-early middle age-all groups were tested for their performance in a maze.

The brain-plaqued mice that were fed the blueberry extract performed as well as the healthy control mice and performed much better than their brain-plaqued peers fed standard chow.

A look at the plaqued brains of both the blueberry-fed and chow-fed mice after death revealed no difference in the number of brain plaques in either group. "Amyloid-beta-induced plaques are only one aspect of Alzheimer's disease," says Joseph. "But the fact that we saw a dietinduced behavioral difference, despite a similarity in plaque density in both these animal groups, is significant."

The team found increased activity of a family of enzymes called "kinases" in the brains of the amyloid-plaqued mice that were fed blueberry extract. Two kinases found in particular, ERK and PKC, are important in mediating cognitive function, such as converting short-term memory to long-term.

"These kinase molecules are involved in signaling pathways for learning and memory," says Joseph. "It could be that the increased kinase activity within the plaque-ridden brains of the blueberry-fed mice enhanced the signaling in certain receptors."

Brain Cells Are Born
Another HNRCA rat study looked at the aged brain's ability to change physiologically- a condition scientists refer to as "neuronal plasticity." In addition to cell division and differentiation, or "mission assignment," brain tissue undergoes many other changes throughout aging.

For example, a newborn sprouts billions of nerve cells while soaking up information from the environment. But lower levels of synapse growth continue in waves throughout the lifespan.

Littleused synapses are eliminated, while others are strengthened in a neuronal pruning process, of sorts.

Repair mechanisms involve neural immune cells, called "microglia," that seek to heal and protect injured brain tissue; enzymes that regulate safe chemical levels; and genes that are expressed in response to inflammation.

The neuronal-plasticity study investigated the physiological link between nutrition and the memory-control hippocampal area of the aged brain. That region, in the center of the brain, is essential for what's called "working" or "short-term" memory. It receives and processes data, and then, if needed, passes it on for storage.

Neurogenesis also plays a role in the formation of new memories. The capacity of the hippocampus to produce new neurons is thought to be greatly diminished during aging. But this study suggested that old rats fed blueberry extracts for a short time had increased neurogenesis in the dentate gyrus area of their brain's hippocampus. The dentate gyrus is one of the few regions of the brain where neurogenesis occurs.

"We found changes in the proliferation of neurons in blueberry-fed rats," said Gemma Casadesus, formerly a graduate student with the Neuroscience Laboratory and now with Case Western Reserve University. In maze tests, blueberry-fed aged lab rats showed improvement in cognition over chow-fed peers. "There was an association between the proliferation of neuronal precursor cells and better performance of spatial memory," she says.

The researchers don't yet know whether the cognitive improvements seen in the aged blueberry-fed rats translate to humans. "But it's an important step in learning about the brain's ability to rescue itself from age-associated declines in physiological function," Casadesus says.

Can You Hear Me Now?
Neurons that can't get their messages through signaling pathways are like cell phones that can't get their signals through to other cell phones. Why does this happen?

As the brain matures, cell division becomes largely restricted to specific regions of the brain, and brain cells tend to become more vulnerable to two partners in crime: oxidative stress and inflammation.

In the body, free radicals-weakened atoms formed during activities of daily living-are missing an electron and want to bond with neighboring biomolecules to stabilize. The problem is that unless neutralized, free radicals cause cellular damage known as "oxidative stress."

Cellular antioxidant defense systems counterbalance these rogue molecules, but they're not 100 percent effective-particularly as the body and brain mature. And the brain is thought to be especially vulnerable to oxidative stress.

"Weighing just 3 pounds, the brain accounts for only 2 percent of the body's total mass, yet it uses up to half of the body's total oxygen consumed during mental activity," says Joseph.

"Phytochemicals, together with essential nutrients in foods, provide a health-benefits cocktail of sorts. It is feasible that continued research in this area will point to dietary regimens that are effective in boosting neuronal function."

Inflammation is thought to be stoked by the overactivation of microglia-the neural immune cells mentioned earlier.

Microglia are usually dormant, but they migrate to the site of any brain injury. These sentries make up about 20 percent of the cell population in certain regions of the brain.

While seeking to protect and repair tissue, microglia cells produce and send out molecular stress signals, some by way of defensive cytokines, as a bugle call to other cells. Those signals begin a cascade of reactions, including the activation of genes that express proteins and other stress chemicals to help clear away cellular debris.

Microglial activation by amyloid beta is thought to be a key event in the progression of Alzheimer's disease. "When microglia are stuck in an always-on loop in response to plaque buildup in the brain, they become problematic in and of themselves," says Joseph.

This year, Francis Lau, a molecular biologist in the Neuroscience Laboratory, published a study that investigated whether blueberry extracts could have a preventive effect on inflammatory signals coming from activated microglia cells.

Microglial activation is considered the hallmark of inflammation in the central nervous system. For this study, Lau used a rodent microglial cell line that has previously served as a model to study plaqueinduced microglial activation.

Lau exposed groups of those test cells to various levels of blueberry extracts. He then challenged the cells with oxidative stress by exposing them to a toxin-lipopolysaccharide- that triggers secretion of inflammatory chemicals.

Neuroinflammation has been linked to the expression of genes that spew two inflammatory enzymes, iNOS and COX-2, and two cytokines, IL-1b and TNF-a.

Lau used real-time PCR (polymerase chain reaction) to find and measure expression of genes that produce iNOS and COX-2 in the stress-induced cell cultures. He found that the blueberry treatment significantly reduced that expression.

The blueberry extract also markedly lessened secretion of the two inflammatory cytokines. In fact, says Lau, "In cells exposed to the highest blueberry extract concentration, the amount of TNF-a cytokine found was next to nothing- essentially identical to that found in the control cells."

Looking to the Future
The food industry is now using a range of new and existing product ingredients to gain entrance into the emerging brainhealth market. Some are producing food labels that list ORAC values-for example, for use on containers of polyphenol-rich fruit juices and teas. So far, however, there has been no review conducted by the U.S. Food and Drug Administration on health benefits from eating berries.

Future studies at HNRCA will ideally include use of new diagnostic tools as well as human clinical trials. Neuroimaging equipment, for example, could be used to monitor the influence of various dietary factors on development of plaque within the human brain. Such studies aim to find the best dietary regimens to help adults preserve their mental capabilities while aging.-By Rosalie Marion Bliss, ARS.

Farms Shield Kids From Bowel Disease

(HealthDay News) -- Children regularly exposed to farm life as babies are about half as likely as other kids to develop Inflammatory bowel disease such as ulcerative colitis or Crohn disease, German researchers report.

The findings, published in the August issue of Pediatrics, fall into line with what experts in inflammatory bowel diseases (IBDs), allergy and asthma call the "hygiene hypothesis."

That theory "refers to the observation that children living in environments with lower levels of microbial exposure seem to be at higher risk for the development of allergies," explained the study's lead researcher, Katja Radon, of Ludwig-Maximilians-University in Munich.

Crohn's and ulcerative colitis are autoimmune illnesses, where the body's immune system mistakenly attacks its own tissues. It is possible that this dysfunction may originate, at least in part, in how immune responses develop very early in life, said Dr. Joel Rosh, director of pediatric gastroenterology at Goryeb Children's Hospital, part of the Atlantic Health System in Morristown, N.J.

He pointed out that while rates of IBDs are holding steady in the developing world, they are rising sharply in more affluent nations.

"It's something that we are doing to ourselves," Rosh said.

"The thinking is that if your immune system isn't appropriately challenged at the appropriate time in life, then it might do some wacky things," Rosh added. In other words, a too-clean environment -- while healthy in some ways -- might be less than ideal when it comes to immune-linked illness, experts say.

The German study is one of the first to compare inflammatory bowel disease rates against infant exposures to farm animals and farm life. The German team questioned the parents of more than 2,200 6- to-18-year-old children. More than 300 of the children had ulcerative colitis, another 444 had Crohn's, and almost 1,500 were free of either illness.

Kids with either Crohn's or ulcerative colitis "were less likely to have lived in rural environments and were less likely to have farm contact in the first year of life, before the disease had developed," Radon noted.

In contrast, children who had spent regular amounts of time visiting or living on farms during their first year of life were 50 percent less likely to develop Crohn's as they got older and 60 percent less prone to ulcerative colitis, compared to youngsters who had not had that experience.

Early exposure to cattle, especially, appeared to help keep the diseases at bay, cutting the odds of Crohn's by 60 percent and colitis by 70 percent, the study authors said.

Cattle appeared to have a more potent effect on IBD risk than exposure to household pets, the study found. Household cat and dog exposure has been the focus of much study and debate among allergists and immunologists.

In this study, regular exposure in infancy to cats reduced Crohn's risk by just 20 percent, a statistic the researchers described as only of "borderline significance." Cat exposure was somewhat more useful against colitis, with rates dropping by 50 percent compared to unexposed children.

The cat-cattle discrepancy didn't come as a big surprise to Rosh.

"It seems that it's not so much animals, per se, as it is which animals," he said. "So, the domesticated cat that stays in the corner cleaning himself all day may not be 'dirty enough' to save you."

Radon agreed. "It has also been shown for allergies that farm animal contact is more efficient [in reducing risk] than pet contact. Therefore, it is not surprising that we see the same for inflammatory bowel disease," she said. "The reason might be that the level of exposure to bacteria and fungi in the farm environment is much higher than if you have a cat or dog at home."

Rosh has his own theories as to where the protective element might lie. "They sanitize it in the article, but they do say it can't be a clean animal -- it's got to be livestock. It's got to be something in that environment, and I would say, it's not in the air so much, as in the poop," he said.

So, does all this mean that modern-day babies need to get "back to the land"?

Perhaps not, according to the experts.

"You can't make the leap to say that to protect our children against autoimmune disease, we need to take them to farms, because we don't know yet what the [protective] exposure is," said Dr. Peter Mannon, head of the Clinical Inflammatory Bowel Diseases Research Unit at the U.S. National Institute of Allergy and Infectious Diseases.

"Are you supposed to be exposed to hay? To a particular type of vermin? The rats in barns? It's very hard to know," he said. While there's no reason not to bring infants to more pastoral settings, "I would not guarantee that it is going to add any protection," Mannon said.

Radon agreed that "at the moment, we cannot give direct advice to parents" since the study showed no cause-and-effect relationship, only an association.

And she pointed out that society's obsession with cleanliness does have its rewards. "We should not forget that an improved level of hygiene has relevantly contributed to today's health in industrialized countries," she said.

For his part, Rosh said there might be some virtue in letting kids get a little dirty -- a prescription most youngsters should have no problem with.

"I don't mean that we all have to eat dirt, but if we could isolate what is in it that is good, maybe we'd have a good [IBD] treatment," he said. "These various areas of research are going to unlock the secrets that we need to cure these diseases."

Simple Workout Urged for Pregnant Women on Bed Rest

(HealthDay News) -- Pregnant women restricted to bed rest can and should do safe, specially-designed physical activity, say experts at the American Physical Therapy Association (APTA).
Each year in the United States, an estimated 700,000 women with high-risk pregnancies (including nearly all those carrying triplets or more) are put on bed rest, the APTA said. But, in many cases, the incapacitating effects of total bed rest are not being addressed, leaving some expectant mothers ill-prepared for pre- and post-partum physical and psychological challenges.

"As a result of prolonged bed rest, pregnant women experience an array of symptoms ranging from cardiovascular deconditioning, musculoskeletal discomforts, stressful postures and positions, skin breakdown, muscle weakness, as well as psychological issues such as guilt, stress, and depression," Jean Irion, a professor of physical therapy at the University of South Alabama in Mobile, said in a prepared statement.

Irion teaches physical therapists across the United States to develop safe physical activity programs for pregnant women on bed rest.

"Physical therapy is often equated with exercise, and many physicians equate exercise to a strong potential for exacerbating a given high-risk condition, so they don't suggest pregnant women restricted to bed rest see a physical therapist. This is a huge mistake," according to Irion.

She said physical therapists work to minimize loss of muscle tone and strength and to make the women as comfortable as possible.

"We're not training these women to compete in a triathlon following delivery. Our aim is for these women to maintain some strength, flexibility and range of motion in the upper and lower extremities, so they'll be prepared for the demands of lifting carrying, and holding their babies," Irion said.

Breast-Feeding Helps Shield Babies From HIV

(HealthDay News) -- By breast-feeding only, HIV-positive mothers reduce the risk of postnatal HIV infection in their babies, South African researchers report.

The study, published in the March 31 issue of The Lancet, also found that early introduction of animal milk and solid foods while breast-feeding increases the risk that infants will be infected with HIV, the virus that causes AIDS.

The findings suggest that current World Health Organization, UNICEF and UNAIDS infant-feeding guidelines need to be revised, said researchers from the University of KwaZulu-Natal.
They found that infants of HIV-positive mothers who received formula milk in addition to breast milk were nearly twice as likely to be infected by HIV as infants who received breast milk only. The addition of solid foods increased the risk of HIV infection in the infants 11-fold.
The death rate at three months for babies who were fed animal milk or solid foods was more than double that of babies who received breast milk only, the researchers found.

"The key finding of our study is the definite demonstration that early introduction of solid foods and animal milks increases HIV transmission risks compared with exclusive breast-feeding from birth. These data, together with evidence that exclusive breast-feeding can be supported in HIV-infected women (and uninfected women), warrant revision of the present UNICEF, WHO, and UNICEF infant feeding guidelines that were revised in 2000," the study authors wrote.

Baby Chicks Linked to Salmonella

(HealthDay News) -- With Easter just 10 days away, many parents are probably thinking about giving baby chicks to their children as pets. But doing so can put kids in harm's way, because the animals may carry a serious -- and potentially fatal -- germ called salmonella, U.S. health officials warn.

Federal researchers have traced 81 infections and three outbreaks of salmonella in 2006 to the handling of baby chicks.

"This is a long-standing issue," said Dr. Pascal James Imperato, chairman of the department of preventive medicine and community health at the State University of New York Downstate Medical Center, in New York City. "We know that chicks and ducklings are often carriers of salmonella."

When these animals are touched by young children, the risk of fecal oral contamination is very high, Imperato said. "For most people in the United States, it is inappropriate for parents to give children baby chicks," he said.

The U.S. Centers for Disease Control and Prevention estimates that there are 1.5 million cases of salmonella poisoning each year in the United States from a variety of causes.
"In recent years, there have been more outbreaks associated with exposure to chicks," said Dr. Nicholas Gaffga, a CDC medical epidemiologist, adding this could be due to better reporting of cases.

Reporting in the March 30 issue of the Morbidity and Mortality Weekly Report, CDC researchers cited three outbreaks last year, including one in Kansas where 10 children who handled baby chicks at a day-care center were infected with salmonella.

A couple of months later, 46 people in Kansas came down with the same strain of the disease after buying chicks. Eight of these people were hospitalized. Many of the people who bought the chicks wanted them as pets for their children, according to the CDC report.

The other outbreaks occurred in Michigan and in Washington state.

"The CDC recommends that children under 5 years of age do not have contact with baby birds," Gaffga said. "If older children touch baby birds, they should wash their hands with soap and warm water for at least 20 seconds."

In addition, clothes, tables, bathtubs, floors -- anything the bird touches -- should be considered contaminated until they are properly cleaned, Gaffga said.

Gaffga also noted that chicks that are dyed Easter colors are even less safe than un-dyed chicks. "Chicks are dyed to make them more attractive to children," he said. "Many states prohibit the sale of dyed chicks. This is to prevent them from being sold to children as pets."

Imperato said that while hand-washing can prevent the transmission of salmonella, it's not something easily monitored, especially among small children. "Parents should really avoid giving children baby chicks as pets," he said.

According to the CDC, salmonella is a bacteria that produces an infection called salmonellosis. Most persons infected with salmonella develop diarrhea, fever, and abdominal cramps 12 to 72 hours after infection. The illness typically lasts four to seven days, and most persons recover without treatment.

But for some, the diarrhea may be so severe that the patient needs to be hospitalized. In these patients, the infection may spread from the intestines to the blood stream, and then to other body sites, and can cause death unless the person is treated promptly with antibiotics. The elderly, infants, and those with impaired immune systems are more likely to have a severe illness, the CDC said.

Zinc Supplements Save Poor Children's Lives

(HealthDay News) -- In the developing world, daily zinc supplements can reduce the risk of death in children aged 1 to 4, but they do not provide any significant benefit for babies under 1, U.S. researchers report.

Zinc, which is one of the most plentiful trace elements in the body, is believed to play an important role in healthy immune system function.

The study, by a team from the Johns Hopkins Bloomberg School of Public Health in Baltimore, included more than 42,500 children in the East African nation of Zanzibar. Half the children received daily zinc supplements (5 milligrams for infants, 10 milligrams for children 12 months and older), while the other half received a placebo pill.

Overall, children who took the zinc supplements were 7 percent less likely to die than those who took the placebo. In children aged 12 to 48 months, those taking zinc supplements were 18 percent less likely to die.

"This large trial demonstrates that the benefits of zinc supplementation include mortality reduction in addition to the reduction in cases of pneumonia, diarrhea and malaria that we found in previous trials," study senior author Dr. Robert Black, professor and chairman of the Bloomberg School's department of international health, said in a prepared statement.

The study appears in the March 17 issue of The Lancet.

"While further work is needed to evaluate higher dose effects, recommendations for use of zinc as a preventive strategy needs to consider the collective evidence of the effect on growth, morbidity and mortality, which would suggest benefit in children age 6 months and up," lead author Sunil Sazawal, an associate professor in the department of international health, said in a prepared statement.

Circumcision Reduces HIV Rates, U.S. Studies Confirm

(HealthDay News) -- U.S. researchers in Africa said Wednesday that they found that circumcision is such a good defense against HIV infection that they shut down two studies early, and instead offered all participants a chance to be circumcised.

One study in the east African country of Kenya showed that circumcision cut adult males' HIV infection risk from heterosexual intercourse by 53 percent, while another study in Uganda lowered the risk by 48 percent, according to results released Wednesday.

The findings, financed by the U.S. National Institutes of Health (NIH), pointed out that the latest conclusions confirmed previous investigations into the value of circumcision as a protection against HIV, the virus that causes AIDS. This is especially important in Africa, where AIDS is an epidemic in many countries, infecting an estimated 25 million people on the continent.

Despite the good news, there is still plenty of reason for caution, AIDS experts said.
"Male circumcision is a difficult intervention to implement, and the preventive effect is relative, not absolute," said Thomas Coates, an AIDS specialist and a professor of medicine at the University of California at Los Angeles. "The magnitude of effect is 50 to 60 percent, which still leaves ample room for people to get infected with HIV."

There are other caveats as well: The study did not look at male-to-female transmission, and it was also not clear whether circumcision makes it less likely that gay men could transmit HIV to each other.
In the United States, homosexual transmission of HIV is more common than heterosexual transmission, the experts said. And most men in the United States are circumcised, making the procedure less effective as a possible prevention tool.

Still, the findings could have plenty of meaning in Africa, where HIV is commonly spread between men and women.

Studies have suggested the value of circumcision in the past, but researchers wanted to confirm the previous findings.

According to the NIH, most adult Africans are circumcised, but the rate drops below 20 percent in some areas of southern Africa where HIV and AIDS are common.

In one of the two studies, researchers enrolled 2,784 HIV-negative, uncircumcised men in Kenya beginning in 2002. The other study, in Uganda, started in 2003 and enrolled 4,996 HIV-negative, uncircumcised men.

Some of the men were assigned to immediately undergo circumcision, while others had to wait two years.
Then researchers studied whether the circumcision had any effect on their rates of getting HIV.
The results were so encouraging that an oversight board halted the studies this week, and ordered that all participants be given circumcisions instead of having to wait.
In Kenya, researchers found that only 22 of the 1,393 circumcised men in the study were infected with HIV, compared to 47 of the 1,391 men who had yet to be circumcised.

The numbers for Uganda weren't immediately available.
"Circumcision is now a proven, effective prevention strategy to reduce HIV infections in men," Robert Bailey, a study investigator and professor of epidemiology at the University of Illinois at Chicago, said in a statement.

It's not entirely clear how circumcision reduces HIV infection. But researchers have suggested that the foreskin may provide a moist, safe environment for the AIDS virus and provide more immune cells for HIV to infect.

Coates called the study results the "second greatest finding in HIV prevention," right behind research that confirmed drugs could stop mother-to-baby transmission of the AIDS virus.
Still, he added, "combination prevention" remains crucial -- combining circumcision with using condoms, reducing sexual partners, and delaying the first time people have intercourse.

The Associated Press reported that the link between male circumcision and HIV prevention was first noted in the late 1980s. The first major clinical trial, of 3,000 men in South Africa, found last year that circumcision cut the HIV risk by 60 percent.

Taping Doctors' Conversations Helps Parents of Newborns in Intensive Care

(HealthDay News) -- Parents of infants hospitalized in intensive-care units are often upset and stressed and don't always fully understand what the doctors are telling them.

But by taping the doctors' conversations, parents can review the talks later and understand exactly what they were being told and the advice being offered, according to a report by Australian researchers.

"Patients, especially when stressed or in a state of shock, find it difficult to recall information given by senior doctors," said lead researcher Dr. Tieh Hee Koh, a neonatologist and clinical director at the Women's and Children's Health Institute of James Cook University Medical School, in Douglas, Queensland. "Even if we doctors discuss at length with the patients about their conditions, they may still not recall anything," he added.

For the study, the researchers recruited 200 mothers with babies in neonatal intensive care. The women were put into two groups: One group had their consultations with doctors recorded and were given a copy of the recording. The second group did not receive a recording.

After 10 days, and then again at four months, the mothers were asked to recall the diagnosis, tests, treatment and outcome of their babies, as explained by their neonatologist.

Koh's team found that women who received a tape recalled significantly more about diagnosis, treatment and outcome, than mothers in the control group. "Six of the 100 mothers not given the tapes did not recall any of the conversations," he said.

The study is published in the Dec. 2 edition of the British Medical Journal.
Although the tapes did not affect the mothers' levels of anxiety or depression, 96 percent listened to the tapes and found them helpful. Moreover, among babies with poor outcomes, the mothers who got tapes were significantly more satisfied with the conversations with the doctors than those who didn't get tapes, the researchers found.

The study authors believe that this method of improving communication between doctors and family members and patients can be extended to other areas of medical care.
Koh, who has been using this method for 12 years, advises "buying a tape recorder for anybody going into hospital or for any doctor friends."

One expert thinks the taping method isn't necessarily the best way for patients and family members to get the medical information they need.

"Patients never hear what doctors tell them," said Dr. Charles Safran, an associate clinical professor of medicine at Harvard Medical School and an expert in patient-doctor communication. "It's not surprising in neonates, where parents need a Ph.D. in intensive care to even remotely understand what's happening to their kid, [that they] don't remember what their doctors tell them."

Safran thinks there's a need for better communication, and the answer may rest with the Internet. Using Web-based, interactive communication allows people to access the information they need as they need it and helps improves communication between doctors and patients and patients' families.

"Web-based intervention, where there is persistence of information, where information, rather than just being given in one large taped session, is made available where and when a parent needs it, has a huge value," Safran said. "When you do that, you can improve parent satisfaction dramatically."

Childhood Cancer Survivors More Likely to Have Preemies

(HealthDay News) -- New research delivers mixed news for women who survive cancer as children: The odds are good that they will bear normal babies, but they still face a higher risk of premature birth.
Women who underwent high-dose radiation therapy to their uterus seem to be the most likely to have problems. The authors of the study, published in the Oct. 18 issue of the Journal of the National Cancer Institute, found that half of babies born to a sampling of these women were premature, compared to roughly 20 percent among their sisters.
"The findings were significant, and they should become part of the arsenal of information that both patients and physicians consult to guide the appropriate long-term care of cancer survivors," said study author Lisa Signorello, an assistant professor of medicine at Vanderbilt University.
In recent decades, improvements in treatment have allowed most childhood cancer patients to survive into adulthood and consider having kids of their own. As a result, "doctors and researchers have started to turn their attention to the long-term effects of cancer treatments," Signorello said. "That is, once a patient makes it through the actual treatment, what can they expect in terms of long-term health for themselves and even for their future children?"
Some treatments can make children infertile for life, but researchers don't know much about potential risks for women who can become pregnant, she said.
Enter the new study. A team of American and Italian researchers studied a database of 2,201 children who were born to 1,265 female survivors of childhood cancer between 1968 and 2002. They compared them to 1,175 children of 601 sisters of those with cancer.
About 21 percent of the babies of all cancer survivors were born prematurely, compared to 13 percent of the other babies.
In addition to having a much higher risk of premature birth, the cancer survivors who had undergone high-dose radiation to the uterus were more likely to have babies with low birth weight (36 percent vs. 8 percent).
The babies of these women were also more likely to be smaller than they should be, based on how long they'd been in the womb.
"Radiation damages not only cancer cells but also the body's normal cells and tissues," Signorello said. "It's likely that radiation causes long-term damage to the structure of the uterus, to the musculature, and even the vascular tissues that supply blood to the uterus. On the positive side, we found that the radiation dose to the uterus needed to be quite high to result in these problems."
It's not clear how the babies fared after birth, although researchers plan to study the health of the children. Still, Signorello said, premature birth or being born too small can lead to lasting health problems.
What should survivors of childhood cancer do? The research "doesn't mean that they shouldn't get pregnant or have children. It just means they should have advice along the way," said Leslie Schover, a professor of behavioral science at the University of Texas M.D. Anderson Cancer in Houston, who wrote a commentary accompanying the study.
"A chief take-home message is that each individual situation is pretty complex, and you really should talk to your oncologist about your cancer treatment and what kinds of risks you would or wouldn't have in getting pregnant or having children after your cancer," added Schover, who studies reproductive and mental health among cancer survivors.

Protein Linked to Lung Development Identified

(HealthDay News) -- Research that uncovers a protein pathway critical to lung development holds the promise of new treatments for premature babies who suffer from respiratory distress syndrome.
"There is a lot of work that must be done, but at least we have a new set of molecules for which, if a receptor is found, intervention is possible," said study author Vrushank Dave, an assistant professor of pediatrics at University of Cincinnati Medical Center.
"This is the first signaling pathway that has been identified for lung maturation," Dave said. In their research, which is published in the Sept. 21 online issue of the Journal of Clinical Investigation, his team found the protein calcineurin is necessary for lung tissue development at birth.
The study was performed in fetal mice and identified a specific signaling pathway for genes that controlled how lung tissue developed. That's good news because until now, the controlling proteins for the final stages of lung development have not been identified.
"It is critical to understand that this work was done in mice, so we can't make a blanket statement saying that the (research) will translate into humans," Dave cautioned.
Still, the animal work is important because right now, there's no definitive treatment for premature babies who develop respiratory distress syndrome, Dave noted. Lungs fully develop very late in pregnancy, so premature infants are at risk for lung disease when they're born. Currently, mothers at risk for preterm delivery are given a single shot of a corticosteroid to help reduce the chances of their babies developing these conditions.
"Prenatal corticosteroids for the prevention of respiratory distress syndrome improves lung maturation; it has some confounding problems," Dave said. These infants are at a very high risk of dying, despite aggressive treatment that can include a mechanical respirator.
Almost one-fourth of premature infants develop respiratory distress syndrome because the cells that line their lungs are not fully developed, so they can't breathe properly; about 60,000 children in the United States are born each year weighing less than three pounds. Of those who survive, many suffer permanent lung damage, which can slow growth, increase the possibility of infection, and result in abnormal brain development.
The current study sheds some much needed light on the syndrome. The researchers deleted the calcineurin b1 gene in the respiratory cells of fetal mice, which stunted lung maturation and caused respiratory failure. The gene deletion decreased the synthesis of surfactant and other proteins necessary for lung development. Because they lacked the protein calcineurin, the newborn mice could not breathe properly and died soon after birth, the researchers wrote.
The mouse research may apply to premature infants because "failed lung maturation at birth results in surfactant deficiency, causing respiratory distress in the perinatal period," the authors wrote.
Future treatment will hinge on more basic science. "The idea is to find the receptor for the [calcineurin] pathway, and we don' have it at this point," Dave said.
The hope is that the description of this pathway that controls the final stages of lung development in mice might help researchers design treatments to manage respiratory distress syndrome and lung disease in premature babies.
Once the receptor is found, "we would like to find molecular targets for the receptor. If we can find that receptor, then it would be possible to see how much we can increase lung maturation," Dave said.
Finding a receptor for the pathway would activate it, but "that's not only the pathway involved. This is very complex phenomenon -- in the last few days before birth, a lot of structural and functional changes in lung are going on," he explained.
This research, Dave stressed, is in its infancy. "We don't know the therapeutic target. This (approach) would work if there's a defect in the receptor pathway, but if there's a cellular defect, that can't be cured with this research," he said.

Weight Concerns Spur Women to Smoke Again After Pregnancy

(HealthDay News) -- Weight-gain worries may help drive women who quit smoking during their pregnancy to start up again after delivery, new research shows.
U.S. researchers interviewed 119 pregnant women in their third trimester who had smoked at least eight cigarettes a day but quit when they became pregnant.
Of those women, 65 percent said they were highly motivated to avoid cigarettes after delivery, and 74 percent of expressed confidence that they'd be able to do so.
"Motivated women were more likely to say they could control their weight without smoking and less likely to say they used smoking to control their weight," study author Michele Levine, of the University of Pittsburgh Medical Center, said in a prepared statement.
The study also found that women who were motivated to remain cigarette-free after delivery were also more likely to say they planned to breast-feed their babies.
The findings dealt only with what the women said they intended to do after delivery, not what they actually did, noted Boston psychologist Elyse Park, who was not involved in the study.
"Most women who are smoking want to quit during pregnancy, but the reality is that very few of them are able to do so. Even in women who are successful, very few are able to maintain quitting," Park said in a prepared statement.

Children's Health

Children's Health
In this section many common questions related to children’s health are explored.

Contrary to popular belief, children are not "little adults," and the approaches to their health conditions are often markedly different than those used for grown-ups.

The rapid changes that occur during growth and development require special consideration in choosing both treatments and medications.

In some cases, specific treatments have not been well studied in children, but the majority of childhood health concerns are those that parents have been asking about for many generations, and the solutions are tried and true. Information on other childhood conditions can be found in the QA archives.

Acupuncture
In the United States, acupuncture hasn’t often been used to treat children, mainly because youngsters tend to be afraid of needles.

But several recent studies have suggested that this fear can be overcome and that children can benefit from acupuncture treatment for certain conditions.

The latest study on this subject was conducted at the Harvard-affiliated Children’s Hospital in Boston by Yuan-Chi Lin, MD, an anesthesiologist who specializes in pain management in children. Dr. Lin’s study included 243 youngsters ranging in age from six months to 18 years who were being treated for headaches, stomachaches, back pain and other chronic complaints that often caused them to miss school.

When the study began, the young patients rated their pain as an "8" on a scale of 1 to 10. (One of Dr. Lin’s methods of demonstrating to the kids that the needles won’t hurt is by inserting them first in the children’s parents.)

When the year-long study was over, the average pain rating among the youngsters was a "3." The kids also reported missing less school, sleeping better, and being more able to participate in extracurricular activities as a result of treatment.

In an earlier study at the same hospital, 70 percent of the 47 youngsters participating reported that acupuncture helped relieve their pain and 59 percent of their parents agreed.

The conditions for which these patients were treated included migraines, endometriosis in teenage girls, and reflex sympathetic dystrophy (a syndrome in which pain becomes chronic after an injury).

In this study, 15 children were age 12 or under while 32 were between 13 and 20 years old. Other studies have looked at acupuncture as a treatment for attention deficit hyperactivity disorder and cerebral palsy in children.

While not many acupuncturists specialize in treating children, Dr. Lin estimates that about a third of pediatric pain centers nationwide now offer acupuncture to their young patients.

Acupuncture is best used for pain reduction as part of comprehensive treatment that includes relaxation techniques, clinical hypnosis and various forms of bodywork.

Attention Deficit Disorder
Ritalin, a stimulant, remains the most common treatment for Attention Deficit Disorder (ADD), also called Attention Deficit Hyperactivity Disorder (ADHD). Paradoxically, with ADHD the drug has a calming effect, apparently because it stimulates parts of the brain that regulate activity and attention.

While it can have excellent results in some cases, it is greatly over-prescribed.
There currently is no herbal treatment for ADHD, except possibly coffee, which may work like Ritalin for some patients.

Pediatrician Sandy Newmark, M.D., of Tucson, Ariz., confirms that no herbs have been found effective for treating the main or "core" symptoms of ADHD — that is, lack of focused attention that often leads to poor school performance. And he doesn’t think coffee is a good long-term solution. However, Dr. Newmark notes that herbs can help with some of the associated symptoms. For example, valerian tea can help youngsters with sleeping problems and St. John's wort can help relieve depression. For children under 12, use half the adult dosage.

Dr. Newmark does recommend a dietary supplement, omega-3 fatty acids, for all children with ADHD because levels of omega-3s in the plasma and red blood cells of children with ADHD are lower than in normal children. He also recommends that youngsters with ADHD take a quality multivitamin as well as a good probiotic, a product that contains "friendly" bacteria that can stabilize the digestive tract. You can find milk-free brands in health-food stores.

Make certain that the underlying cause of your child’s disruptive behavior really is ADHD, and that he or she isn’t acting out difficulties at home or expressing frustration with a learning disability. Be sure to rule out hearing or vision problems, allergies, depression or even boredom in a gifted child.

As far as foods are concerned, while there’s no evidence that a dietary approach helps in all cases, a 1993 Cornell University study found that eliminating dairy products, wheat, corn, yeast, soy, citrus, eggs, chocolate, peanuts, artificial colors and preservatives seemed to decrease ADHD symptoms. An even earlier study showed that a low-allergen diet supplemented with calcium, magnesium, zinc and vitamins produced favorable results.

Asthma from Exercise
Exercise can trigger asthma symptoms in children and adults – even those who don't otherwise suffer from the condition - and can aggravate the problem in up to 80 percent of those who do have asthma.

The symptoms – coughing, wheezing, shortness of breath or tightness in the chest – usually come on after exercise, although they can occur soon after exercise has begun. It can be treated with medication and by taking precautions to prevent or minimize symptoms. Here’s a rundown of medication options, provided by pediatrician John Mark, MD, an assistant professor of pediatrics at the University of Arizona who treats asthma in both adults and children.

Albuterol – A short-acting bronchodilator that’s inhaled 15 to 20 minutes prior to exercise and that protects against symptoms for about four to six hours.

Salmeterol – A long-acting bronchodilator that’s inhaled twice a day which offers protection for up to 12 hours. You can also use salmeterol as a preventive before you work out.

Montelukast (Singulair) – A drug that blocks the action of leukotrienes in the lungs, resulting in less constriction of bronchial tissue and less inflammation. Leukotrienes are one of several classes of chemical messengers produced in the body that can trigger bronchial constriction and inflammation. Montelukast is available in pill form and is taken the night before you exercise.

Cromolyn (Intal) – An anti-inflammatory drug inhaled 15 to 20 minutes before exercising that prevents the release of histamines and leukotrienes. It’s most useful in asthma when an allergic component is present.

In addition to medication, the following approaches can help prevent or minimize symptoms:
A very slow warmup. Even to the point that your child reports the beginning feelings of the "tightness" associated with exercise-induced asthma.

Then your child should stop and stretch, or slow down if exercising vigorously. By taking this break, the development of asthmatic symptoms can often be blocked and a normal pace can be resumed. This may take some getting used to, but can sometimes eliminate the need for medication.

Try breath work. The most effective approaches are pranayama techniques – breath control exercises taught in some yoga classes for adults. You can have your child do these after the initial warm-up, again, when the symptoms are almost felt. For most children, you can start with Dr. Weil’s technique for "The Relaxing Breath."

Find a form of physical activity that minimizes exercise-induced symptoms. Sports or activities that have intermittent rest periods (such as tennis, softball and golf) can allow your child to regain control of his or her breathing. Swimming may be better than running outdoors in cold weather, but no type of exercise is off-limits with proper treatment. In fact, some of the world’s top athletes have exercise-induced asthma, and they’re still able to compete successfully in Olympic-level events.

Bedwetting
Although by age 8 most youngsters have outgrown bedwetting, a sizeable minority still haven’t. As a matter of fact, 5 to 10 percent of boys still have enuresis (the medical term for bedwetting) by age 10. Enuresis tends to run in families and, when this is the case, children usually outgrow it at the same age as the parent, sibling or other relative who had the problem did.

No one knows what causes bedwetting, although it is sometimes associated with constipation. If so, simple dietary changes such as eating more fruits and vegetables and drinking more water early in the day can help resolve matters. Pediatrician Sandy Newmark, MD, of Tucson, Ariz., suggests making sure that children aren’t drinking any beverages that contain caffeine (such as some sodas) and trying to limit (within reason) the amount of fluids they drink in the evening.

Dr. Newmark explains that an "enuresis alarm" is the most simple and effective intervention for youngsters. This device is a wristwatch with a sensor that is attached to pajamas so that the alarm sounds at the first sign of wetness.

This system eventually conditions a child to wake when the bladder is full. Dr. Newmark says that the alarms work in about 70 to 80 percent of children. They are available at most drugstores and cost about $50. Be patient with this system since it can take weeks, and sometimes months, to see results.

If the alarm doesn’t help, Dr. Newmark suggests trying hypnosis as a safe and effective treatment. While some pediatricians prescribe drugs for children who wet the bed, using medication is controversial and should be viewed as a last resort. Homeopathic remedies also may be effective; consult a homeopathic practitioner if you want to try this approach.

Broken Bones
Results of a recent study at the Mayo Clinic in Rochester, Minn., suggest that the rate of wrist and forearm fractures among young girls has increased dramatically in the last 30 years. The study results, published in the Sept. 17, 2003, issue of the Journal of the American Medical Association showed that the fracture rate for young girls increased 56 percent from 1969-1971 and 1999-2001.

Boys still suffer more fractures, but the rate of increase among young boys was only 32 percent. Overall, the Mayo Clinic researchers found that the fracture rate among young people had increased 42 percent over three decades.

The researchers had no answers for why this is happening. It is unlikely that youngsters are breaking more bones because they’ve become more physically active. One possibility is that kids may not be getting enough calcium during a period when their bones are growing rapidly.

If so, their bones may never become as dense as they should, which raises the possibility that affected youngsters may be more vulnerable later in life to osteoporosis and hip and vertebral fractures.

The researchers noted that government surveys have shown a decrease in milk consumption among older girls and an increase in consumption of carbonated drinks. The phosphates in carbonated beverages interfere with calcium absorption.

The RDA for calcium is 1,300 mg for young people age 9 to 18. This translates to 4-5 servings of dairy per day, but kids don’t have to drink milk to get their calcium. Other good sources include yogurt, cheese, sea vegetables, collard and mustard greens, kale, bok choy, broccoli, canned salmon and sardines, tofu that has been coagulated with a calcium compound, calcium-fortified soy milk, fruit juice and blackstrap molasses.

Other experts have noted instances of vitamin D deficiency that could contribute to weakened bones. Our bodies make vitamin D with exposure to sunlight, and youngsters who spend too much time indoors may not produce optimal amounts of vitamin D. Spending 10 minutes in the sun without sunscreen a few days each week will do the trick, but it is not a bad idea for kids 12 and older to take a multivitamin supplement that includes 400 IU of vitamin D.

Carsickness
Carsickness, like all types of motion sickness, occurs when the brain receives conflicting signals from the inner ears, eyes, and other parts of the body that sense motion. A child sitting in the back seat of a car may sense movement – her inner ear perceives the motion – but she may not be able to see out the window to see that she is moving. At the same time, her perception is that her body isn’t moving at all. In some children, these conflicting messages can result in very distressing nausea.

One effective remedy for motion sickness comes from an old Chinese fisherman’s remedy of stimulating the acupressure points that control nausea. The updated version of this treatment is done with wristbands equipped with a plastic peg that presses on acupressure points on the inner surfaces of the wrists. The wristbands are available at most drug and health-food stores. Follow package directions carefully – proper placement of the wristbands is critical.

Motion sickness can also be prevented (and treated) with ginger. Mix a half teaspoon of ginger powder in a glass of water and give it to your child 20 minutes before you get in the car. Or give your child two capsules of powdered ginger.

This remedy has proved more effective than Dramamine – with none of the drowsiness that can occur as a side effect of the drug. Ginger snaps, ginger ale and candied ginger can all help with mild nausea, so keep some in the car should someone develop symptoms during the trip. You also could explore homeopathic remedies – and possibly hypnosis – as a long-term solution.

The American Academy of Pediatrics suggests trying to deal with carsickness in children by focusing youngsters’ attention away from their queasiness. Listen to the radio or tapes, sing or talk. Also, direct their attention at things outside the car, not at books or games. Make sure that they look out the front windows, where apparent motion of objects is less.

Colicky Babies
First, exclude other reasons for the baby’s crying. Make sure the infant isn’t running a fever, isn’t lethargic, is eating normally and isn’t having any trouble breathing. Your pediatrician will also want to exclude GERD (gastroesophageal reflux disease), which can occur among babies (although it is much more common among adults).

The good news about colic is that what you see is what you get – a fussy, crying but otherwise perfectly healthy baby. Some doctors think that this irritating phase may be part of normal development. Between 5 and 28 percent of infants develop colic between when they are two to six weeks old, and usually outgrow it by the time they’re three to four months old.

Here are Dr. Russell Greenfield’s suggestions for dealing with colic – and with the frustration it can breed among parents:

  • Try massage therapy, a great way to enhance bonding between parent and child at a time when colic may be interfering with the bonding process.
  • Rock your baby rhythmically.
  • Turn on music or try the clothes dryer or vacuum cleaner. Sometimes the white noise they produce helps.
  • Try cranial osteopathy or homeopathy; both may help and are safe forms of treatment.
  • Try herbal remedies such as cooled chamomile or fennel tea. You can get tea bags at the health food store and give the baby one to two ounces at a time, no more than three to four ounces per day.
  • Switch to a cow’s milk-free formula, or, if breast feeding, change the mother’s diet to affect what is entering her breast milk (in some cases, a food sensitivity may play a role).
    Swaddle your baby – it provides a nice snug feeling.
  • Chill – find a way to relax; try breathing exercises or other relaxation techniques to lower your frustration level.

By the way, the latest international report on colic comes from a Canadian study that found that mothers don’t appear to sustain any lasting psychological effects as a result of dealing with a colicky infant.

Constipation
Constipation is a common problem for children and usually is temporary. Strictly speaking, a child is constipated if he or she has fewer than three bowel movements per week or if the stools are hard, dry, and unusually large or difficult to pass. Because constipation can make bowel movements painful, youngsters may try to avoid having them. (In addition, about 60 percent of constipated children experience recurrent abdominal pain, a common stress-related condition in youngsters.)

The causes of constipation in kids usually are simple and relatively easy to correct: not enough fiber in their diets, not drinking enough liquids or not getting enough exercise. Then, too, constipation can occur when youngsters ignore the urge to have a bowel movement, which they can do for reasons ranging from not wanting to take a break from playing to embarrassment at using a public bathroom or because a parent isn’t around to help when the urge occurs.

Medication can also be a factor. Those that can cause constipation include aspirin and codeine, vitamins with high doses of iron, the bismuth in Pepto-Bismol, as well as some chemotherapy agents (vincristine) and some psychiatric drugs (imipramine).

Sandy Newmark, MD, a pediatrician at the University of Arizona Program in Integrative Medicine, recommends the best ways to deal with constipation in young children, listed here:
Decrease dairy products: They can be constipating. Provide your child with an alternative source of calcium such as soy milk fortified with calcium or a calcium-fortified breakfast cereal.
Increase fluids: Encourage your child to drink lots of water.

Increase fiber: Give your child lots of high-fiber fruits and vegetables as well as high-fiber cereals, whole-grain breads and beans.

Although these measures probably will do the trick, if a child’s episodes of constipation last longer than three weeks and prevent him or her from participating in normal activities, you might want to consult a pediatrician. Don’t be tempted to administer the over-the-counter laxatives designed for children. They can be dangerous to youngsters and should be given only under the direction of a pediatrician.

Ear Infections
Recurrent ear infections can be troublesome during early childhood. Here are two strategies:
Eliminate milk and milk products from your child’s diet for at least two months. This means avoiding all dairy products as well as other foods containing milk in any form. Soy, rice, and nut milks such as almond milk are all right. The protein in milk, casein, is often associated with recurrent ear infections in early life as well as with sinus conditions, eczema, chronic bronchitis, and asthma.

Try cranial osteopathy. It is another good treatment for recurrent ear infections. When performed by a skilled practitioner, this technique can often end cycles of ear infections, sometimes with a single treatment.

The late Bob Fulford, D.O., a leading practitioner of cranial osteopathy, had great success curing recurring infections in young children. He believed that fluid stagnation in the middle ear – caused by restricted breathing – was at the root of the trouble.

Gentle manual manipulation (and sometimes application of a vibrating instrument known as a percussion hammer) opens up breathing, which in turn helps fluid drain from the middle ear. To find a practitioner of cranial osteopathy, send a self-addressed stamped envelope to the Cranial Academy, 8202 Clearvista Parkway, #9D, Indianapolis IN 46256. At the University of Arizona, researchers are now concluding a study funded by the National Institutes of Health's National Center for Complementary and Alternative Medicine on the use of both cranial therapy and Echinacea to break cycles of recurrent childhood ear infections.

Early Puberty
In the United States, there's a virtual epidemic of precocious puberty these days – the onset of puberty at very young ages in both boys and girls. Among Caucasian girls today, 1 in 7 starts to develop breasts or pubic hair before she is 8 years old. Among African-American girls, the number is 1 out of 2! Unfortunately, no one knows why this is happening, although there's plenty of speculation. Precocious puberty can be triggered by tumors in the pituitary gland, hypothalamus, ovaries, or testicles, but these cases are rare. Environmental factors are more likely to blame for the upsurge in cases today. The theory with the most scientific support is that obesity is responsible. I think this may be true, since we've long known that overweight girls mature physically earlier than thin ones.

Research also has suggested that environmental pollution may play a small role. In the spring of 2000, results of a study reported in the Journal of Pediatrics showed that boys exposed to DDE (a breakdown product of DDT) were heavier than their peers, while girls exposed to PCBs were heavier than their peers and tended to reach puberty a bit sooner, even though the actual numbers involved in the study were not deemed statistically significant. (Both DDT and PCBs are chemicals that appear to interfere with the body's own hormones.) Researchers are also looking at other environmental chemicals – among them Bisphenol A (BPA), used in manufacturing plastic – but so far haven't found a definitive link.

Unfortunately, there's not a lot to offer in terms of treatment and no natural remedy that I can suggest. Since it's occurring so often these days, some physicians believe that precocious puberty in girls between the ages of 6 and 8 should be seen as normal and not treated at all. (We do know that the risk of breast cancer later in life increases with an earlier onset of puberty.) The only approved allopathic treatments are two drugs: Gonadotropin-Releasing Hormone, GnRH, and Luteinizing Hormone-Releasing Hormone, LHRH, both given by daily injections or at intervals of every three to four weeks. These drugs interfere with the hormonal changes responsible for precocious puberty, in effect putting them on "hold" until the child reaches a more appropriate age (typically between the ages of 11 and 13 in girls). The drugs may also reverse the changes that already have taken place.

The physical changes are only one aspect of what girls must contend with as a result of precocious puberty. Because they look like young women, they're often treated as if they were much older than they are by boys (or men who should know better) and may also be teased by friends and at school. If you are a parent with a child in the midst of precocious puberty, you must keep the parent-child lines of communication open. Make sure that your child understands that despite the change in her appearance, he or she is still a child.

Fluoride
The only children who need fluoride supplements of any type are those who live in communities without fluoridated water supplies or in homes with water purifiers that remove minerals. The easiest, most efficient and most cost-effective means of making sure that children have adequate fluoride to protect against tooth decay is to support fluoridation of your area's water supply.

If your community's water is not fluoridated, your child will need dietary fluoride supplements which are available only by prescription from your dentist or physician. To protect against tooth decay, children need fluoride on a daily basis from the age of 6 months to 16 years. (Pregnant women take fluoride supplements beginning in the sixth month of gestation to ensure strong tooth development in the fetus – check with your obstetrician about this.) The correct dosage for your child must be calculated on the basis of the natural fluoride concentration of your local drinking water as well as your child's age, and the extent of his or her exposure (if any) to other sources of fluoride, such as toothpaste or commercial products.

Some fluoride is present in all water sources, but according to the American Dental Association, most bottled waters don't contain enough to prevent tooth decay. Fluoridation of community water supplies involves adjusting the fluoride content to the optimal level for dental health, 0.7 to 1.2 parts fluoride per million parts water. Too much fluoride can be bad for children's teeth, just as too little is bad. An excess of fluoride can lead to mottled, chalky, white spots on the teeth. Other health risks include weight loss, brittle bones, anemia and weakness. Be aware that there are conflicting reports that continue to fuel the controversy over fluoridation. Yet at proper levels, fluoride is of immeasurable benefit to the teeth – during childhood and throughout life.

Food Coloring
We are seeing more and more strangely colored foods and snacks, but as a precaution, keep children – and adults – away from foods with artificial colorings. The danger is that the chemicals used to create color are energetic molecules, many of which are capable of interacting with and damaging DNA. Anything that damages DNA can injure the immune system, accelerate aging, and increase the risk of cancer. Indeed, many synthetic food dyes once considered safe have turned out to be carcinogenic. Some approved for use in Europe are considered unsafe in the United States, and vice versa.

Dyes are added to foods for the convenience of the manufacturer, not for the health of the consumer. Luckily, these are among the easiest types of food additives to avoid. Try to convey to your children that garishly colored snack foods are weird and unhealthy – rather than attractive – and make it a rule not to buy them. Watch out for labels that list any of the following terms: "color added," "artificial color added," "U.S.-certified color added," or "FD&C red No. 3" (or green or blue or yellow followed by any number; these are FDA-approved food drug and cosmetic dyes).

There is nothing wrong with foods dyed with natural colors obtained from plants. The most common, annatto, is from the reddish seed of a tropical tree. It is widely used in Latin American cooking to make yellow rice and breads, and is also commonly added to butter and cheese to make them yellow or orange. Other safe food colorings are a red pigment obtained from beets, a green one from chlorella (freshwater algae), caramel, and carotene from carrots.
Definitely keep your kids away from bright green ketchup, a product designed specifically to appeal to youngsters.

Head Lice
Head lice are a common nuisance of childhood. Kids pick them up from someone who already has them by wearing each other’s hats, scarves, hair ribbons and other clothes; sharing combs, brushes or towels; or lying on a bed, couch, pillow or even cuddling a stuffed animal that belongs to a child who has lice. Try to discourage this kind of sharing, particularly if you hear that there’s an infestation at school, at a day care center, or wherever your children spend time.

The conventional treatment is one-percent lindane, sold as Kwell lotion. Yet lindane is a cousin of DDT and can harm the nervous system. Natural and safer alternatives include one-percent permethrin cream rinse, sold as Nix and Neem, which is derived from a tree in India. Lice can develop resistance to permethrin products, and they can aggravate asthma in some children, but both are relatively nontoxic. (Neem is sold in garden shops.)

Some California school systems are using a new product called Lice B Gone, a non-toxic, multi-enzyme shampoo made from plant sources that seems to get rid of lice in a single application. It works by softening the glue that holds the nits (lice eggs) to the hair shaft and also dissolves the exoskeletons of adult lice. Since it contains no pesticides, Lice B Gone is considered safe for pregnant women, nursing mothers, young children and people with asthma.

Overweight Kids
You'll probably be happy to hear that not all children who are heavy grow up to be overweight adults. However, we do have an epidemic of childhood obesity in the U.S., and all parents should be aware that for every year that a child remains overweight, his or her chances of growing into an overweight adult increase.

Aside from eliminating sodas or junk food at home, look to physical activity as a way to help your child lose weight. Try for at least half an hour of physical activity each day. Unfortunately, only 25 percent of school-aged children now take physical education classes. If your child doesn't get any exercise at school, it's up to you to make sure he or she does some type of physical activity at home.

Here are some approaches to add exercise to your child's life as well as foods that will help control his or her weight:
Curb screen time. Limit the time your child spends watching television, sitting at the computer or playing video games.
Set a good example. Studies have found that children are more likely to be physically active if their parents and siblings are active, and if they're encouraged to take part in physical activities. Take family walks, hikes or bike rides on a daily basis, if possible.
Emphasize nutritious foods. Don't limit the amount your child eats, but make sure the foods he does eat are low in fat and high in fiber. When making these changes, say that you're doing it for the entire family to avoid drawing attention to your child's need to lose weight.
Eat meals together. Family breakfasts and dinners give you more control over what your child eats and allow you to make sure that everyone gets at least two nutritious meals per day.
Think about drinks. Cut back on fruit juices, sodas and whole milk. Drinks can provide a surprisingly large number of calories per day.
Teach a relaxation technique. If your child eats in response to stress, you might show him how a relaxation technique such as deep breathing can help to calm him.

Sore Throat
The most important thing parents can do when children develop sore throats is to make sure that the problem isn’t strep, a bacterial infection that requires antibiotic treatment. Strep is diagnosed via a throat culture. (Or a rapid strep test, which takes only 10 minutes but is not as accurate.) While the results may not be available for a few days, a doctor often can tell on the basis of observation whether strep is the likely problem and begin immediate treatment with penicillin. The sore throat usually eases in 24 to 48 hours.
Besides a very sore throat, symptoms of strep often include fever, swollen and tender lymph glands under the jaw, and a swollen and marked redness at the back of the throat that may have white dots. Those symptoms don’t always mean strep, but they often do. (Another clue: suspect strep when there are none of the typical symptoms of a viral infection such as a cough, runny nose, hoarseness and eye irritation.)
It is very important to treat strep throat with antibiotics as soon as possible, because in rare cases it can lead to an autoimmune reaction – rheumatic fever – that can affect the joints, heart and kidneys.
To reduce your child’s susceptibility to sore throat, try to build up his or her immune system by administering a course of the Chinese herb astragalus (Astragalus membranaceous) during cold and flu season. You can get astragalus in tincture form or in capsules at the health-food store. Administer one half the adult dose. This herb is safe for regular use.
If your child can gargle, give her a mixture of half hot water and half hydrogen peroxide to use several times a day. Gargling with warm salt water (one-quarter teaspoon salt to one cup of warm water) is also soothing.

Teething
In many infants, the process of teething is painless, causing only some increased drooling and a desire to chew. However, some infants develop tender, swollen gums, may not sleep or eat well, and may run a low fever (under 100 degrees). A fever above 100 degrees or diarrhea suggests problems unrelated to teething.
Here are some recommendations to keep a teething baby comfortable:
Wipe the drool off your baby’s face with a soft cloth (to prevent rashes).
Rub the baby’s gums with a clean finger.
Let your baby chew on a wet washcloth that has been placed in the freezer for 30 minutes (wash it after each use). Alternatively, use a cool spoon or rubber teething ring (take it out of the freezer before it gets so hard that it bruises the tender gums).
Never tie a teething ring around a baby’s neck – it could get caught on something and strangle the child.
Homeopathic teething tablets are a good option. Many parents tell me they have used them successfully to relieve the minor discomforts of teething in their babies.

Toy Safety
Look over the toys you have at home to see if they are age-appropriate for your children. In general, this means making sure they aren't too advanced for the youngest child, but sufficiently sophisticated for the older ones. Homes with infants or toddlers should make sure all toys (and their removable parts) are large enough so they can't be put into a child's mouth and become a choking hazard. (An easy test: A child can choke on any object that fits inside the tube from a roll of toilet paper.)
Parents or grandparents should also be aware that over the last two years toy manufacturers have recalled teethers, rattles, and other products that contain a cancer-causing chemical called diisononyl phthalate (DINP) from the market. Phthalates are used to soften plastics, but high doses have been linked to cancer in mice and rats. The U.S. Consumer Product Safety Commission has said the amounts that might have been ingested by small children are not high enough to pose a risk, but it does make sense to toss any soft plastic rattles and teethers that you’ve had more than a year – that's when most toy manufacturers agreed to phase out use of the additive.
The following guidelines for toy safety are from the American Academy of Pediatrics and the Consumer Products Safety Commission:
Check the surface and edges of wooden toys. Sandpaper sharp corners and splinters.
Don't give hobby kits, such as chemistry sets, to children younger than 12.
Don't permit children to play with adult darts or other hobby or sporting equipment that have sharp points.
Examine all outdoor toys regularly for rust or weak parts that could become hazardous.
Discard all plastic wrappings on toys before they become deadly playthings.
New toys intended for children under age 8 should be free of glass and metal edges.
Toys with long strings or cords may be dangerous around infants and very young children. Never hang toys with long strings, cords, loops, or ribbons in cribs or playpens where children can become entangled.
Keep toys designed for older children out of the hands of little ones.

Vitamins
Yes, children should take vitamins, mostly because so many kids don’t eat enough fruits and vegetables, and because their diets are often full of processed and refined foods. However, vitamin supplements shouldn’t be substitutes for whole foods, especially fruits and vegetables.
Teach children of any age to enjoy healthy food by involving them in its preparation, even if they’re only in the kitchen to observe. In "The Healthy Kitchen," Rosie Daley and I give a number of ideas for recipes and snacks that kids will like. Also, try to discourage your children from eating too much fast food, processed food, sugar and caffeine (in cola and other soft drinks). There’s no harm in the occasional ice cream, pizza or candy bar in the context of a well-balanced diet, but try to encourage snacking on healthier foods – fresh or dried fruit; a small handful of raw, unsalted nuts such as cashews and walnuts; a piece of flavorful, natural cheese; or a piece of dark chocolate.
As far as supplements are concerned, give children a complete antioxidant formula as well as multiminerals. Be sure to keep the vitamins out of the reach of young children – some supplements for kids taste and look like candy and there is a danger of overdosing, especially when supplements contain iron.
