Calcium Scans Help Predict Coronary Risk

(HealthDay News) -- Scanning the heart arteries for calcium deposits can help predict future cardiac problems, a new study shows, but experts aren't sure that adding such scans to routine checkups would be worth the cost.

"It has been shown to be predictive" of potential heart trouble, said Dr. Diane Bild, deputy director of the division of prevention and population sciences at the U.S. National Heart, Lung, and Blood Institute, which funded the study. "Whether it is actually beneficial to the people who are screened has not been shown."

A calcium scan using computed tomography (CT) costs $300 to $600. These scans look for calcification -- hardening of the arteries caused by high blood fats and calcium deposits that can eventually cause blood vessel blockage. The scan is a potential competitor for much less expensive tests for coronary risk, such as blood cholesterol and blood pressure readings.

The new study involved more than 6,700 American men and women across a number of racial and ethnic groups -- white, black, Chinese, Hispanic -- who were followed for an average of 3.8 years. It found that the risk of a coronary event was nearly 10 times higher for those with the highest calcium deposit scores than for those with the lowest.

"This study was launched in 1999, a time when there was a lot of interest in whether this new test could predict coronary artery disease," Bild said. "A lot of studies have been done in predominantly white populations. This was one of our efforts to include minority groups."

The study does show that calcium scanning "modestly improves predictions over traditional risk factors," she said. "Several pieces of information are needed in order to understand whether this is clinically useful."

The findings are published in the March 27 issue of the New England Journal of Medicine.

The cost of such scans could be reduced, according to a statement from study lead author Dr. Robert Detrano, professor of radiological sciences at the University of California, Irvine, who is traveling in China. Scans have been done for just $30 in China, Detrano noted.

"It is mostly an issue of cost," said Dr. William S. Weintraub, chief of cardiology at the Christiana Health Care System, the largest health-care system in Delaware, who wrote an accompanying editorial in the journal. "It does add to our discrimination, but it costs a couple of hundred dollars and we're not sure how you use it."

Reducing the cost would make the test more usable, and "more epidemiological studies showing its value in risk prediction would be of great value," Weintraub said.

"But I'd be uncomfortable now with the idea of recommending this for everybody, or even defining a middle ground where we are unsure how we treat people so they get this first," he said.

A calcium scan also carries some risk, since it exposes a person to radiation, Bild noted. "It would be worth it if the benefit outweighed that risk," she said. "We don't clearly have both sides of that equation established."

Anxiety Helps Elderly Women Live Longer

(HealthDay News) -- Higher anxiety levels may help elderly women live longer, but may harm older men, U.S. research shows.

A team at the Cleveland Clinic and Case Western Reserve University followed 1,000 seniors in three Florida retirement communities for up to 15 years.

They found that women with higher levels of anxiety at the start of the study lived longer than others. Year-to-year changes in anxiety levels didn't appear to affect women's survival, either.

In contrast to women, men with higher anxiety levels at the start of the study were more likely to die earlier, the researchers said.

"Our research indicates that anxiety may have a protective effect on women, possibly causing them to seek medical attention more frequently than men," Dr. Jianping Zhang, of the department of psychiatry and psychology at the Cleveland Clinic, said in a prepared statement. "In contrast, increasing anxiety over time is more detrimental to men. Additional research is needed to better understand the mechanisms and effects of anxiety in men and women."

The study is noteworthy due to the large amount of data collected over a long period of time, noted co-researcher Dr. Leo Pozuelo, who is also in the department of psychiatry and psychology at the Cleveland Clinic.

"Baseline higher anxiety could have led the female study participants to be more active and health-conscious," Pozuelo said in a prepared statement. "We are not certain of the absolute connection between anxiety and mortality, but this data set shows there may be a gender difference."

The study was to be presented Thursday at the annual meeting of the American Psychosomatic Society.

Terriers Join Fight Against a Killer Disease in Humans

(HealthDay News) -- A feisty breed of terrier could stop scientists from barking up the wrong tree as they research a deadly lung disease in humans.

The illness, called idiopathic pulmonary fibrosis (IPF), affects 128,000 Americans, is typically fatal within three years of diagnosis, and kills more than 40,000 people in the United States annually -- a death toll equivalent to that of breast cancer.

A fatal condition that looks remarkably like IPF also strikes the diminutive West Highland White terrier ("Westie"), however. And recently, medical scientists from the human and veterinarian worlds met for the first time to share information and pool resources against a mysterious killer.

"People may be a little startled at first to learn about this idea -- 'You're kidding me, you actually think there's promise in studying this dog to help my Dad with this disease?' And the answer is -- 'Yes'," said Mark Shreve, chief operating officer of the patient advocacy group Coalition for Pulmonary Fibrosis, based in San Jose, Calif.

Because the Westie is so tightly bred, and because the illness progresses faster in dogs than humans, it is conceivable that dog-based research might yield valuable clues to the genetics or environmental factors that trigger pulmonary fibrosis in both species, experts explained.

"And if it transpires that it is the same disease, then obviously the options are limitless as to how we can look at information from dogs and use it to understand the disease in humans and vice versa," said Dr. Brendan Corcoran, director of the Hospital for Small Animals at the University of Edinburgh, Scotland, and a pioneer in researching pulmonary fibrosis in Westies.

According to Shreve, most people find it hard to believe that a disease like IPF even exists amid the wonders of modern medicine.

"We are dealing here with one of the few diseases left on the planet for which there are no proven causes and no treatments," he said.

Idiopathic pulmonary fibrosis occurs spontaneously, although certain factors -- such as smoking or exposure to airborne toxins -- do raise risks for the illness. "IPF is a progressive scarring process in the lungs that gradually robs a person of the ability to breathe," Shreve explained.

Some sort of signaling seems to go awry at the cellular level, he said, converting normal, expansive lung tissue into stiff, fibrotic scar tissue.

"Once it starts in patients with IPF, your body just never sends a signal to stop that scar tissue from being produced," Shreve said. "This scar tissue is obviously not lung tissue that is able to process oxygen."

There have so far been very few promising leads in discovering the root causes of IPF, said Dr. Jesse Roman, one of the country's leading researchers in the disease and a professor of medicine at Emory University in Atlanta.

"Studies do suggest very specific [cellular] pathways, and there's a number of molecules that everybody is tuned into," he said. "But how you block them and how they relate to what happens in humans, that's less clear."

So, scientists are turning to creative new ways of looking at IPF.

Cross-talk between scientists worldwide led to the first-ever summit on the disease that included both veterinary and human medical researchers. The meeting was held in October on the campus of Purdue University in West Lafayette, Ind., and was attended by Corcoran, Roman and others. It was sponsored by the Westie Foundation of America and the American Kennel Club (AKC) Canine Health Foundation.

Westies, which grow to just under a foot in length, are described by the AKC as "courageous and self-reliant, but friendly."

"They're a very popular pet because of their size and their nature," Corcoran said.

However, pulmonary fibrosis does pop up in the breed with regularity, first revealing itself as excessive panting and shortness of breath. The illness also tends to develop in the terriers' late middle-age (about eight or nine years), mimicking its typical onset in humans at about age 50 to 60.

Westies inevitably succumb to the lung fibrosis about a year and a half after their diagnosis, Corcoran said.

Still, "there's still the contentious issue of whether this is the same disease as occurs in humans," he said. The exact prevalence of the disease among Westies is also unclear, he added. That means the first aim of Westies-centered research will be epidemiological -- studying disease prevalence and gathering a core of dogs and their owners that researchers might follow going forward.

Getting postmortem samples of canine lung tissue will also be crucial to a better understanding of the causes of the disease, Corcoran said. But that has its own challenges, he added.

"Getting owners to volunteer their dogs for necropsy is always problematic," he said. In fact, it's often "harder in many instances to get lung pathology samples from dogs than it is from humans," Corcoran said.

"However, one of our plans is to try and build up a group of concerned owners who will volunteer to donate their dog when that day arrives. We've been having some discussions on that already with our colleagues in America," Corcoran said. "Hopefully, the more publicity that we get with this condition, the more we may get owners coming forward and volunteering their dogs for research."

Corcoran and the other experts said that a cure for IPF is definitely not around the corner -- the disease has been as tenacious in keeping its secrets as, well, a terrier.

But Westies may be just the foe in the fight against IPF requires. Corcoran pointed out that the dogs' tight breeding means genetic research could yield important clues. And their shorter lifespan -- a seventh of that of humans -- means scientists can watch the disease in "fast-forward," which might also speed research.

Westies are also free of certain confounding factors, such as smoking, that often muddle human research. "The dogs might turn out to have a very pure form of the disease that allows you to investigate the disease itself and not worry about other factors," Corcoran noted.

Given all of this, "why wouldn't you look at a Westie and research how the disease progresses?" said patient-advocate Shreve.

"We think it's a very creative approach to trying to help out humans," he said, "and our patients don't really have the patience to hang around waiting for a miracle.

Realistic Expectations Help Ward Off Holiday Depression

(HealthDay News) -- For many people, heightened expectations, financial and social stress, and memories of lost loved ones can cause tension, anxiety and sadness.

All of that can lead to seasonal blues during the holidays, says an expert at Cedars-Sinai Medical Center.

For example, people who expect difficult relationships to improve just because it's Christmas are likely to be disappointed.

"In terms of relationships, nothing magical 'just happens' during the holidays," Dr. Mark H. Rapaport, chair of the department of psychiatry and behavioral neurosciences at Cedars-Sinai, said in a prepared statement.

"If you don't get along with your in-laws during the year, you're probably not going to get along with them during the holiday season, either. Understanding that before you go to visit them can improve how you'll handle your feelings while you're there," he said.

Planning ahead can help people cope with many sources of holiday-related stress and anxiety.
"If you plan ahead and focus on what you really enjoy about the season, you can spend more time 'living in the moment,' which is the key to getting the most out of each holiday experience," Rapaport said.

He offered some tips for coping with the holidays:

• Have realistic expectations about interactions with family and friends.
• Make a list and prioritize activities that you feel are most important.
• Limit your drinking. Too much alcohol can lead to bad behavior, hangovers, and remorse which, in turn, can lead to depression.
• Share holiday responsibilities such as shopping, cooking, party planning, and activities.
• Get regular exercise. Walking for just 30 minutes three times a week can give you a big boost.
• Keep your holiday spending under control.
• Eat well, get enough rest, and make time for yourself.
• Spend time with caring and supportive people and reach out to those who may benefit from your support.
• Don't worry too much about details. Live in the moment as much as possible and look for meaningful moments throughout the season.

Health Tip: What's Plantar Fasciitis?

(HealthDay News) - Plantar fasciitis is a common condition -- caused by overuse -- and characterized by often severe pain in the heel.

The American Academy of Orthopaedic Surgeons offers additional information about the condition, including its risk factors:

• Women and people who are overweight are more likely than others to develop plantar fasciitis.
• Frequent running or walking for exercise may increase your risk of developing the condition.
• People with flat feet or very high arches are at greater risk.
• Standing or walking on hard surfaces for long periods also may increase your risk.
• The injury usually doesn't hurt during exercise, but pain begins to develop afterward.
• Pain may be most severe when waking up in the morning, or after rest.
• Plantar fasciitis requires treatment to prevent it from becoming chronic.

Cancer Patients Gain From Reporting Symptoms Online

(HealthDay News) -- Having cancer patients report to doctors on their symptoms and side effects online may improve their care, a new study finds.

Even the sickest cancer patients are willing and capable of reporting their symptoms online, says a team from Memorial Sloan-Kettering Cancer Center in New York City.

"Cancer care has become increasingly complex, causing office visits to become more compressed. This makes it challenging for the clinician to comprehensively assess each patient's symptoms in that brief window of time," study author Dr. Ethan Basch, a medical oncologist, said in a prepared statement.

"Because cancer therapies can be highly toxic, early detection of symptoms and timely treatment is vital. What is exciting to us about online self-reporting is that patients can alert clinicians to crucial symptoms in real time," Basch said.

The study included 107 lung cancer patients receiving outpatient chemotherapy who had access to a secure Internet patient reporting system developed by Basch and his colleagues. The patients were able to access the Symptom Tracking and Reporting (STAR) site using computers in waiting room kiosks and at home to report cancer symptoms and chemotherapy-related side effects.

The patients were followed for up to 16 months and 40 visits. All of the patients used the waiting room kiosks at some or all of their office visits, and an average of 78 percent logged onto the system at any given office visit. Patients were more likely to use STAR if they had prior computer experience.

The study found that 98 percent of patients found STAR easy to use, 90 percent said it was useful, and 77 percent believed it improved the quality of their discussions with clinicians.
The study appears in the Dec. 1 issue of the Journal of Clinical Oncology.

Prostate Cancer Treatments Often Compound Existing Health Problems

(HealthDay News) -- More than a third of prostate cancer patients may receive treatments that are inappropriate because of problems they are already having with urinary, bowel or sexual function, a new study suggests.

These mismatches might occur, because patients don't give enough information to their doctor or because their doctor favors a particular type of treatment, according to the report in the Nov. 26 online edition of Cancer.

"We found an awful lot of patients whose treatment seemed to be contraindicated by urinary, bowel or sexual problems they had before they got treated," said lead researcher Dr. James Talcott, from the Center for Outcomes Research at Massachusetts General Hospital Cancer Center in Boston. "That's pretty good evidence that information wasn't transmitted or didn't factor in with the treatment decision."

Unlike other cancers, there are several treatment options for prostate cancer. The treatment that is best for an individual patient is based on several factors, including stage at which the cancer is diagnosed, age of the patient, and existing problems with urinary, bowel or sexual function that the patient has.

Treatments include external radiation therapy; brachytherapy, in which tiny radioactive particles are implanted into the prostate gland, and the surgical removal of the prostate gland.
Although these treatments are effective, each has a different set of side effects. External radiation can lead to bowel dysfunction, brachytherapy can cause urinary problems, and surgery can damage nerves involved in sexual function.

Treating patients who already have problems in these areas with a procedure that could exacerbate their problem is usually not recommended.

For example, treatment designed to preserve normal functions, such as nerve-sparing, prostate-removal surgery, is not appropriate for patients who have already lost sexual function, Talcott said.

To find the extent of treatment mismatches, Talcott's team collected data on 438 prostate cancer patients. Patients were asked to complete questionnaires that included questions about urinary incontinence and other urinary problems, and bowel and sexual dysfunction.

The researchers found that 89 percent of the patients had some level of urinary, bowel or sexual problem before starting treatment. Among these patients, 34 percent of those with one serious symptom had a mismatched treatment, as did 37 percent who had a less serious symptom. Moreover, 40 percent of those who had several symptoms also received contraindicated therapy.

In addition, among patients with significant dysfunction in all three areas for whom no treatment would be recommended, only 5 percent chose watchful waiting. In this strategy, patients are not treated but are followed closely.

These mismatches appear to occur because doctors and patients don't communicate well. Patients are often reluctant to talk about urinary, bowel and sexual problems, Talcott said. "And, sometimes patients override their doctor's recommendation," he added.

Talcott also thinks that physicians can be wedded to a particular treatment at the exclusion of others. "Surgeons believe in surgery, and radiation oncologists believe in radiation," he said. "That may be part of the problem."

To counterbalance physician bias, patients should get another opinion, Talcott said. "Patients should always get a second consult," he said. "It's a good idea to talk with a surgeon, a radiation oncologist and possible a medical oncologist."

One expert thinks that patients need to make an informed decision about which treatment is best.

"The kind of doctor that you see often predetermines the treatment you receive," said Dr. Durado Brooks, director of prostate and colorectal cancer at the American Cancer Society. "Urologists are much more likely to have a surgical solution, and those who see a radiation oncologist are more likely to have radiation."

Patients need to be well-informed about their condition and the possible treatments and their side effects, Brooks said. "Patients need to arm themselves with as much information as possible about what their treatment options are, and what some of the contraindications of particular treatments are," he said.

Men also need to know what all the treatment options are, Brooks said. "Men need to be aware that, in some cases, depending on their overall medical condition and the stage of their cancer, that it is, at times, appropriate not to have any active treatment," he said. "Watchful waiting is a legitimate option in a significant proportion of men."

"In addition, doctors need to work with their patient to choose the best treatment option, Brooks said.

"If one takes the time to have a discussion, educate the patient and not rush them into a decision, then you may be able to allow them to get past their emotional response and make a more educated, logic-based response," Brooks said.

Brooks noted that because there are so many treatment options in prostate cancer, patients may insist on a particular treatment even though it's not the best choice for them.

"Where treatments are contraindicated in other places in medicine, doctors don't provide a treatment for a patient just because that's what they say they want," Brooks said. "You explain that that treatment is simply the wrong treatment for you, and therefore, we are not going to take that approach."

Researching Alternatives: A Talk With Donald Abrams

By Bob Huff
June 2003
You have a reputation as being a rigorous clinical researcher and tough advocate for making evidence-based treatment decisions.

Yet you've also been very open to studying a number of alternative and complementary therapies that have been used in the HIV patient community. How did all these concerns come together and what are you involved with these days?

I was training in oncology at UC San Francisco just as the first AIDS cases were reported. I helped found the AIDS program there and I've been participating in academic clinical research for over 20 years. More recently I've become an associate fellow of the Program in Integrative Medicine at the University of Arizona that was founded by Andrew Weil.

This is a two-year program, mostly online, that is increasing my training and background in integrative medicine, including things like botanical medicine, manual medicine, and spirituality. It's been a stimulating experience so far and I'm really enjoying it.

I've been interested in complementary medicine since the very beginning of my career, so one of the reasons I'm doing the fellowship is to learn more that I can integrate into my own healthcare discussions with my patients. Of course another impetus is to see what other things we might want to do clinical research on.

My intention is to continue to investigate the complementary and alternative approaches that our patients are using. We want to determine whether or not they may be beneficial, but also determine whether or not they may be harmful, particularly in how they interact with the conventional medications that patients are taking.

In the earliest days of AIDS we didn't have any treatment for this new disease; people were dying and everybody was frightened. Being here in San Francisco, we were near the Linus Pauling Research Institute in Palo Alto, so there were a number of people in the city who were proponents of high doses of Vitamin C.

One of the first responses we saw in the early '80s were storefront clinics opening up where people went to receive intravenous injections of very high doses of Vitamin C.

At that point in time we didn't even know that it was a virus causing the disease. So I used to go around on the lecture circuit with someone who would talk to audiences of concerned people who listened to him while hooked up to intravenous infusions of Vitamin C.

Then I would speak as the academician who cautioned people that we really don't know if this is beneficial and there may be some dangers to being hooked up to intravenous vitamin C, and so on. Ultimately, this led to me to write a grant proposal in collaboration with the Linus Pauling Institute.

It was right about the time we learned that HIV was the cause of AIDS so we wrote a proposal to the NIH to study the in vitro effects of Vitamin C on HIV. That grant didn't get funded.

In San Francisco at that time there were also a number of DNCB proponents. DNCB, dinitroclorobenzene, is actually a photographic chemical used for developing pictures, but it is also a skin sensitizer that had been used to test for delayed hypersensitivity reactions.

There were people who believed that somehow it might be useful in restoring some of the T-cell immunity that patients with this new disease were lacking. So there were people who would paint themselves weekly or so with DNCB until they developed these skin reactions, thinking that the skin reaction was some sort of improved T-cell immune response that would help combat the virus.

And again, seeing that people were using this and seeing that we really didn't have much else happening, I worked with some of the DNCB proponents, as well as some experts from the University of California -- I remember Jay Levy was involved, as was Marcus Conant and others -- and we wrote a protocol that we submitted to the FDA for funding. That also was rejected.

Around the time that AZT first became available in 1986, I went to a conference in Japan where I was introduced to some investigators from the Ueno Fine Chemicals company who told me that they had the cure for this disease. They said it was something that was very commonly used in Japan but they couldn't tell me about it until I signed a confidentiality agreement.

That turned out to be dextran sulfate. Not long after I was going through the process of filing the paperwork to get approval from the FDA to do a phase I study of dextran sulfate in the United States when evidently some people heard about it.

They realized that it was a product that was widely available in Japan -- I believe it was used for lowering cholesterol -- so they started an importation scheme similar to what had happened in earlier days with isoprinosine and ribavirin, which were brought across the Mexican border.

But people had now become more sophisticated in their methods and began to import dextran sulfate from Japan to sell in the underground AIDS therapy market.

I remember that activists stormed the offices of a Japanese drug distributor in New York for refusing to make dextran sulfate more widely available. Ultimately it became such a political issue that, even though my clinical trial here in San Francisco didn't show much benefit, Congress got involved and the AIDS Clinical Trial Group (ACTG) was asked to do a study of dextran sulfate through the NIH-funded mechanism. It turned out the drug was not even absorbed into the blood.

Another Japanese product I worked with was lentinin, which was an intravenously administered extract of shiitake mushroom. In Japan it was felt to be an immune booster for patients with cancer. Although it was being used by mainstream doctors in Japan, it was an alternative therapy here because it was not something that we had ever learned about or used in hospitals in the U.S. That's David Eisenberg's description of what an alternative therapy is -- that it's not taught about in medical schools or widely available in U.S. hospitals -- and certainly shiitake mushroom extracts qualified. Again, that's another study we did that had negative findings;

there was no benefit to the intravenous infusions of lentinin. Since I've learned more about botanicals, it would seem to me that if there were immune enhancing benefits to shiitake mushrooms then they are more likely to be obtained by eating them rather than by injecting an extract intravenously.

During that time I was also involved with studies of conventional therapies. Even in the days of early AZT monotherapy, which I was not a big supporter of, I was involved in trying to put some evidence behind the claims of the proponents for these various agents. And since that time, I've had a constant history of investigating conventional therapies through the federally-funded CPCRA (Community Programs for Clinical Research on AIDS), and more recently through the ESPRIT study of interleukin 2, as well as in other, sometimes pharmaceutical industry-sponsored trials. But always ongoing with those studies, I've been involved with clinical trials of complementary and alternative interventions.

When we first became aware of immune thrombocytopenic purpora (ITP) in AIDS, I worked with a nurse who was very interested in therapeutic touch and we studied men with low platelet counts to see if therapeutic touch could decrease their stress and increase their platelet counts. That was another study that turned out to be fairly negative.

I then became interested in traditional Chinese medicine (TCM) and, in fact, one of the colleges of TCM here in San Francisco sent me to China in 1989 just to learn about Qigong (Chi Kung) -- that exercise that's felt to improve the immune system -- to see if it was something that I wanted to study here. Although I never studied Qigong I collaborated with Misha Cohen from the Quan Yin Healing Arts Center here in San Francisco. We did three studies of traditional Chinese herbal interventions for, first, symptomatic HIV, then for patients with diarrhea without a pathogenic source, and then another study for patients with anemia.

The last two were hindered by the fact of being initiated about the time that HAART became available, so patients with diarrhea as well as anemia became scarce. There were also a lot of pills that needed to be taken in these Chinese herbal investigations and patients at that time were taking huge amounts of pills with their antiretroviral regimens, so the studies weren't very attractive. None of these studies had spectacular results and the anemia study was terminated for poor enrollment.

Have "soft endpoints" such as life satisfaction created a problem for designing and conducting credible studies?

The TCM herbal study that we published in 1996 investigated herbs versus placebo in symptomatic HIV infection. At the time of the study in 1993, we had patients with about 14 symptoms on average and we found that there was a significant decrease of symptoms in the herb-treated group -- they decreased from 14 to 12 -- whereas the other group still had 14 symptoms. We also found that they had improved "life satisfaction" which improved by a factor of +0.86 or thereabouts.

Yet, if you look at the rest of the results, the Chinese herbal patients actually lost weight over 12 weeks compared to the placebo group, and their CD4 counts also dropped -- not statistically significant, but it was a trend. So that was an example of where their symptoms improved and their life satisfaction increased, but the parameters that we would normally look at to see if a patient is doing well (i.e., weight and CD4 count) went in the wrong direction. So, although I was also first author on a study that showed that epoetin alfa improves quality of life in HIV patients who are anemic, I'd have to say that a study whose main endpoint is quality of life is something I would find difficult to interpret.

The CPCRA actually did a large study of acupuncture for patients with HIV-related peripheral neuropathy that was published in JAMA. That was a landmark, having the NIH support an acupuncture study, although, again, it turned out to have negative results; acupuncture didn't appear to be effective in treating peripheral neuropathy.

About this time I began trying to study another botanical, which has consumed my efforts for the past decade, and that would be cannabis, or marijuana. Starting in 1992 I began proposing and developing clinical trials to investigate first the effectiveness -- but then I realized that that wasn't going to happen -- so subsequently, the safety of smoked marijuana in patients with HIV.

We finally completed a study in the year 2000, that we hope will soon be published, that looked at the safety of marijuana in patients taking protease inhibitor regimens. And since that time we have obtained funding from the State of California that allows us now to conduct clinical trials to look at the potential effectiveness of smoked marijuana in patients with various syndromes. We have also just completed a pilot study in patients with HIV peripheral neuropathy, which allowed us to ascertain that there was some effectiveness of marijuana. But an open-label pilot study is not going to prove that, so we're now in the process of continuing on with a randomized, placebo controlled, double-blind trial in patients with HIV-related peripheral neuropathy. We're also doing marijuana studies in patients with cancer who have pain who are on opioid analgesics, and another study to look at the effect of smoked marijuana in patients who have delayed nausea and vomiting from breast cancer chemotherapy.

It was working with marijuana and all the problems that are inherent in studying a plant as a therapy that has led me to a broader interest in botanicals and the use of substances that come from nature as medicinal agents. Certainly, for thousands of years, people have depended primarily on these things. Whether or not they worked is unclear, but as an oncologist I know that many of my most potent chemotherapeutic agents were derived from plants. So right now we are waiting to hear if a protocol we submitted to the National Center for Complementary and Alternative Medicine (NCCAM) to investigate the lipid lowering effects of oyster mushrooms in patients on Kaletra is being funded. There's good evidence that mushrooms, including oyster mushrooms in particular, have some activity for lowering blood lipids and cholesterol.

We're also just finishing a three-year NCCAM grant studying the effects of DHEA, dehydroepiandrosterone, which is an over-the-counter adrenal steroid that people are taking for many reasons. We received a grant to investigate it as an antiviral and to see what impact it has on the immune system. Hopefully that data will be available by the end of the year and we will know if DHEA had any impact, positively or negatively, in our patients.

The goal, ultimately, would be to submit a center grant to the NCCAM, to allow us to establish a center here for the study of botanicals in HIV because there are still a number of herbal preparations and mushroom extracts that warrant further investigation for their potential benefit -- and to make sure that they're not harmful in our patients.

Safety keeps coming up again and again as one of the inarguable justifications for doing this research.

There's not a huge amount that we know about some of these botanical products and how they're metabolized, but there's probably more than people think. There are a number of textbooks available that talk about herb-drug interactions. That was the question in our marijuana study: is there an interaction between cannabinoids and protease inhibitors, which are both metabolized by cytochrome P450 enzymes in the liver, that may alter the activity of the protease inhibitors such that patients lose their viral suppression when they mix cannabis with their treatments?

And in fact, in our article that was already published in AIDS, we saw no such effect. We've all heard about garlic and St. John's Wort and their interactions, and I think there are many other agents that we would like to study to make sure that they are not having significant interactions with protease inhibitors. We don't want people to either lose control of their viremia (through underdosing) or experience toxicity (through overdosing) because of antiretroviral concentrations that have been affected by herb-drug interactions.

You had to be enormously persistent to accomplish your marijuana study. In the current political climate, is it going to be more difficult to do marijuana studies?

I think we're blessed to live in the State of California, which is somewhat of a freestanding republic in and of itself. In 1996, the people of California voted to allow physicians to talk to their patients about the medicinal use of cannabis. Then, through the work of Senator John Vasconcellos, one of our state senators, appropriations were made to the University of California that established the Center for Medicinal Cannabis Research (http://www.cmcr.ucsd.edu/). And that Center has had funds for the past three years that allows it to support clinical trials to investigate the use of marijuana for medicinal purposes.

Whereas the NIH and NIDA, via their congressional mandate, could only give marijuana to clinical trials that show that it was harmful (they are the National Institute on Drug Abuse, not for Drug Abuse, as NIDA's director Alan Leshner always reminded me), they were not really able to provide us with marijuana to study the benefits. But now, they have modified their system so they can provide marijuana for peer reviewed clinical trials that will look at its effectiveness as a therapeutic agent -- as long as they are not funding it. So they have now created this ability for us to obtain government marijuana.

Is there a need to increase provider knowledge about these issues?

I think a part of the problem is a lack of communication from both sides. Patients don't really perceive that these substances are something that they need to tell their doctor about -- in fact many studies show they don't want to tell their doctor because they're afraid they're going to be reprimanded or told that they're wasting their money. And many physicians never even think about asking about these things as potential confounders or as things that are causing clinical symptoms.

There also may be a variable of where in the country you are. I know many surveys show that we in the West have the highest percentage of people in the population who are using complementary and alternative interventions. So many of my colleagues here might be more familiar with how to ask the question and what to be looking for.

I remember once seeing a patient at our drop-in clinic who clearly had a drug rash. I looked through his chart -- this was when we had paper charts -- and he had a high CD4 count and a low viral load but he wasn't taking any medications.

So I said to the guy, "You're not taking any medications, huh?" And he said, "No."
"Are you taking any vitamins?" And he said, "Yeah."

So I asked him what he took and he listed about four or five vitamin preparations. Then I asked, "Do you take any herbs?" And he said, "Sure."

And so I listed the three or four herbal substances th
at he took.
"Do you take any minerals?" And he said, "Yeah."
By the time I finished I had a list of 12 different things he was taking.
So I asked, "Well, how come everybody else wrote down that you don't take anything?" And he said, "Well, nobody ever asked me before."

Aromatherapy: The Scent of Dispute

(HealthDay News) -- Aromatherapy is an affordable, accessible natural path to relief for a variety of health problems, ranging from arthritis pain to nausea to drowsiness, supporters insist.

But skeptics dismiss any claims that the use of essential oils from flowers, herbs and trees can promote health in any way.

And both sides are unlikely to relinquish their positions anytime soon.

Aromatherapy "works for so many different things, it is amazing," said Kelly Holland Azzaro, a registered aromatherapist in Banner Elk, N.C., and vice president of the National Association for Holistic Aromatherapy (NAHA), an industry trade group. "You can experience aromatherapy by inhalation by putting one drop of an essential oil on a tissue and inhaling," she said.

According to the NAHA, aromatherapy is the "art and science of utilizing naturally extracted aromatic essences from plants to balance, harmonize and promote the health of body, mind and spirit." These essences are then distilled into "essential oils" -- highly concentrated aromatic extracts -- that are derived from a "variety of aromatic plant material, including grasses, leaves, flowers, needles and twigs, peels of fruit, wood and roots."

Among the most popular essential oils, which are widely sold at health-food stores and over the Internet, are eucalyptus, geranium, lavender, lemon, peppermint, rosemary, and tea tree, and according to the NAHA.

"Uplifting scents such as citrus can keep you awake at work," Azarro said. "To help increase alertness, use rosemary and lemon." And to combat nausea, try essence of peppermint, ginger and orange, she added.

While research into aromatherapy's benefits is limited, there are some studies that suggest certain treatments can help ease some symptoms.

For instance, in a 2005 study published in the journal Chronobiology International, researchers reported that lavender aromatherapy helped all 31 men and women feel more "vigor" the next morning, compared to the night they breathed in distilled water, an exercise that served as the control setting.

A study in the March-April 2006 issue of the Journal of Midwifery & Women's Health said that aromatherapy, combined with massage, helped new mothers feel less "blue" and anxious, compared to mothers of newborns who didn't get the treatment.

And a review published in Holistic Nurse Practitioner found that patients with postoperative nausea and vomiting can be helped by aromatherapy as well as acupressure and acupuncture.
But critics find little of value with scent therapy -- or even label it as therapy.

"It's not a therapy, it's a set of products with odors," said Dr. Stephen Barrett, board chairman of Quackwatch Inc., an Allentown, Pa.-based organization that says it fights health fraud and quackery.

"If people like the odors and want to pay for them, I would have no objection," Barrett said. However, he added, don't expect much. "There is no evidence that aromatherapy can alter the course of any disease. There is no logical reason to believe that any such evidence will ever be found," he said.

As for potential risks, Barrett said: "Some people find certain odors irritating. People who use aromatherapy with the hope that it will cure what ails them will waste money."
Azzaro said that, currently, aromatherapy is unregulated in the United States. "And that's part of the issue," she said. People don't understand exactly what it is, either. "People think it's potpourri or a smelly candle."

There's also no state licensing for aromatherapists in the United States. Most practitioners incorporate their training with another profession, such as licensed acupuncturist or registered nurse, according to the NAHA.

If you're interested in pursuing aromatherapy, Azzaro said it's best to ask a practitioner about his or her specific training. "And when you purchase oil, such as from a health-food store, hopefully some educational materials are with the product," she said.

Be aware, too, there can be the possibility of allergic reactions to some treatments.

Bacopa: A Better Memory Booster?

Bacopa: A Better Memory Booster?

Q: What you can tell me about bacopa? I first read about it as a treatment for memory problems. Do you know anything about its effectiveness in treating memory problems or what the recommended dosage should be?

A: Bacopa (Bacopa monnieri) is an herb native to India that has been used traditionally in Ayurvedic medicine to enhance memory, learning and concentration and also to treat anxiety, heart problems, digestive disorders, asthma, and bronchitis. Most of the research on bacopa has been in animals, but a few small studies on humans have also been done.

The single study I've been able to find on bacopa's effect on memory was a small, double-blind, placebo-controlled 12-week trial conducted in Australia with 46 volunteers between the ages of 18 and 60, divided into two groups.

The volunteers in one group were given 300 milligrams of bacopa daily, and the others received a placebo. Prior to the study, the researchers tested all the volunteers to assess their verbal learning abilities, memory and speed of information processing. The tests were repeated five and 12 weeks after the study began. The researchers noted a significant improvement among the volunteers in the bacopa group compared to those in the placebo group.

A review article of some 38 scientific studies of bacopa was published in the March, 2004, issue of the journal Alternative Medicine Review, and noted two small studies that demonstrated an improvement in cognitive function in children as a result of taking bacopa.

A single small-scale human study also found a decrease in anxiety symptoms among patients treated with bacopa.

Bacopa is now being widely promoted as a treatment for memory problems, but I would recommend more proven protective strategies. Keep your mind active by reading newspapers and books, doing crossword puzzles, playing musical instruments, participating in ongoing education, and learning a new language. As far as supplements to enhance memory are concerned, the ones listed below have been studied more thoroughly than bacopa:

Ginkgo biloba. This well-studied botanical remedy increases blood flow to the head, has a reputation as a memory-enhancing agent and may slow the progression of dementia in early onset Alzheimer's disease. You probably won't notice any effects for six to eight weeks. (Look for products standardized to 24 percent ginkgo flavone glycosides and 6 percent terpene lactones; the dose is 60 to 120 milligrams twice a day with food.) Ginkgo has low toxicity, although it may cause mild stomach irritation.

Acetyl-L-carnitine (also called ALC or ALCAR) is an amino acid derivative. Human clinical studies of this compound are currently underway, and the early evidence from animal trials is encouraging. Many people take ALC as a cognitive enhancer. The dose is 500-1,000 milligrams twice a day on an empty stomach. It is nontoxic, but this is an expensive regimen.

Phosphatidyl serine, or PS. A naturally occurring lipid that is a component of cell membranes, PS is considered a brain-cell nutrient. Human studies have reported positive effects on memory and concentration; PS may improve cognitive function in normal adults and may help reverse age-related cognitive decline. The supplement form, derived from soybeans, is readily available, but fairly expensive. The starting dose is 100 milligrams two or three times a day; if this produces positive benefits after a month or more, it may be possible to go on a lower maintenance dose. It is nontoxic.

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.
