The FDA [has] issued an alert about a possible link between breast implants — saline or silicone — and a rare form of lymphoma called anaplastic large cell lymphoma (ALCL). These lymphoma cases are exceedingly rare, but the association appears to be significant.
The FDA identified a total of approximately 60 ALCL cases in association with implants, worldwide. Of these, 34 were identified by review of published medical literature from 1997 to May, 2010; the others were reported by implant manufacturers and other sources. The agency estimates the number of women worldwide with breast implants is between five and 10 million. These numbers translate to between six and 12 ALCL cases in the breast, per million women with breast implants, assessed over 13 years or so.
In women who don’t have implants, ALCL is an infrequent tumor, affecting approximately one in 500,000 women is the U.S. per year. This form of lymphoma — a malignancy of lymphocytes, a kind of white blood cell — can arise almost anywhere in the body. But ALCL cases arising in the breast are unusual. The FDA reports that roughly three in 100,000,000 women are diagnosed with ALCL in the breast per year in the U.S.
These are very small numbers. Still, the finding of ALCL tumors by the implant capsules is highly suggestive. Almost all of the implant-associated ALCL cases were T-cell type, whereas most breast lymphomas are of B-cell type. The lymphomas arose in women with both silicone and saline-type implants, and in women with implants placed for purposes or augmentation and for reconstruction after mastectomy. Read more »

This picture shows the view from my office window in Boston: Dull, dreary, and depressing — at least on overcast days like today. Lack of light is one of the reasons that people feel mentally foggy.
One of the bloggers I follow, Rachel Zimmerman of WBUR’s CommonHealth blog, recently wrote that she’s been drinking three times as much coffee as usual. In addition to imbibing more caffeine, I’ve been trying to boost my spirits and alertness with mid-day runs to the snack machine (not the best strategy, in case you’re wondering).
At this time of year, many people aren’t just foggy and sad — they’ve got SAD, or seasonal affective disorder. About half a million Americans — women more often than men — are diagnosed with seasonal affective disorder each year. Many others experience at least some of the symptoms, which include loss of pleasure and energy, inability to concentrate, feelings of worthlessness, and an uncontrollable urge to eat sugar and high-carbohydrate foods (in my case, chocolate chip cookies).
Bright white light therapy remains a mainstay of treatment for seasonal affective disorder. That’s because the light acts on cells in the retina, the tissue located at the back of the eye that sends visual information to the brain. The hypothalamus, which helps control the sleep-wake cycle, is one part of the brain that receives this information. During the winter months, when people tend to stay indoors more, days are shorter, and the weather becomes overcast, our exposure to natural light diminishes. That disrupts the sleep-wake cycle, as well as other circadian rhythms. The result can be symptoms of seasonal affective disorder. Read more »

Information circulating about the dangers of plastic containers has created fear and confusion. Are plastic containers toxic? Do harmful chemicals leach out into its contents? Do we need to discard all plastic containers?
Recently, I interacted in a live health chat on MedHelp about the safety of plastics. Scientist, Joe Schwarcz, Ph.D., Director of McGill University’s Office for Science and Society, talked about “The Real Truth About Plastics: What You Should And Shouldn’t Worry About.”
While Dr. Schwarcz states that some plastics like those made by Tupperware and Rubbermaid are safe to use, there are other plastics made of Bisphenol A (BPA) that may cause some concern, however he did not become alarmed.
There is extensive information on the safety of plastics, and reading some of it can easily cause panic and confusion, but the smartest step health consumers can do for themselves is to remain calm and don’t become alarmed. Gather the facts and determine what’s best for you.
The Facts About Bisphenol A (BPA)
Bisphenol A (BPA) is used to manufacture polycarbonate plastics. This type of plastic is used to make some types of beverage containers, compact disks, plastic dinnerware, impact-resistant safety equipment, automobile parts, and toys. BPA epoxy resins are used in the protective linings of food cans, in dental sealants, and in other products.
General exposure to BPA at low levels comes from eating food or drinking water stored in containers that have BPA. Small children may be exposed by hand-to-mouth and direct oral (mouth) contact with materials containing BPA. Dental treatment with BPA-containing sealants also results in short-term exposure. In addition, workers who manufacture products that contain BPA can be exposed.
How Does BPA Get Into The Body?
BPA can leach into food from the epoxy resin lining of cans and from consumer products such as polycarbonate tableware, food storage containers, water bottles, and baby bottles. Additional traces of BPA can leach out of these products when they are heated at high temperatures. Read more »

From the Food and Drug Administration (FDA) safety alert yesterday:
ISSUE: The FDA announced a possible association between saline and silicone gel-filled breast implants and anaplastic large cell lymphoma (ALCL), a very rare type of cancer. Data reviewed by the FDA suggest that patients with breast implants may have a very small but significant risk of ALCL in the scar capsule adjacent to the implant.
BACKGROUND: In total, the agency is aware of about 60 cases of ALCL in women with breast implants worldwide. This number is difficult to verify because not all cases were published in the scientific literature and some may be duplicate reports. An estimated 5 million to 10 million women worldwide have breast implants. According to the National Cancer Institute, ALCL appears in different parts of the body including the lymph nodes and skin. Each year ALCL is diagnosed in about 1 out of 500,000 women in the United States. ALCL located in breast tissue is found in only about 3 out of every 100 million women nationwide without breast implants.
While the FDA’s new report is interesting, as it stands it’s of little consequence. A mere 60 cases of a unusual breast cancer worldwide is a tiny number compared to the huge number who develop the much more common ductal breast cancers (about one in seven women in the U.S.) Breast implants have not been found to affect this more common cancer incidence. I do expect this statistic to be misquoted by the anti-breast implant factions online.
As an aside, I do remember a case in a fellow plastic surgeon’s mother of a lymphoma near a breast implant capsule when I was a resident. This is the only breast cancer of this type I have ever seen, however, in 14 years of practice. While I don’t doubt the association, I do focus on the significance of this report to the average breast implant patient, which is very little at this point.

Good news for parents, teachers, pediatricians, and others engaged in the ongoing battle against lice: The Food and Drug Administration (FDA) just approved a new treatment for head lice in children age four and older. Called Natroba, it’s a liquid that is rubbed into the hair and allowed to sit for 10 minutes before being rinsed off. Natroba is a useful addition to the anti-lice arsenal, since some head lice have become resistant to permethrin and pyrethrins, the active ingredients in over-the-counter anti-lice products such as Nix and Rid.
Head lice are tiny insects that go by the big name Pediculus humanus capitis. They thrive in the warm tangle of human hair, feeding off blood in the scalp and breeding with abandon. A female lays eggs called nits that she attaches to strands of hair. Nits hatch after about eight days, become adults in another week or so, feed for awhile, then begin to make more lice.

What To Do
First off, here’s what not to do: Don’t shave your or your child’s head, or coat it with petroleum jelly or mayonnaise or anything else designed to “suffocate” the parasite. You’ll probably end up with greasy, smelly, lice-infested hair.
Current guidelines from the American Academy of Pediatrics call for the use of an over-the-counter product containing permethrin or pyrethrins as a first salvo against head lice. Shampoos and rinses made with these substances are generally effective. Most treatments for head lice need to be used twice, seven to 10 days apart, along with combing wet hair with a fine-toothed nit comb. Some lice are resistant to pyrethrin and permethrin. Stronger prescription drugs, such as malathion and lindane, also work but aren’t as safe for humans. That’s where Natroba comes in. Read more »
