Hair Care Practices in Black Women With and Without Scarring Alopecia: A Retrospective Cohort Study
FDA: Prostate Cancer Warning Added to BPH Drug Labels
Information about the increased risk of high-grade prostate cancer diagnoses associated with the use of finasteride and dutasteride has been added to the prescribing information for the two 5-alpha reductase inhibitors, which are approved to treat benign prostatic hyperplasia, the Food and Drug Administration announced on June 9.
The information has been added to the warnings and precautions section of the labels for 5-ARIs. Dutasteride is marketed as Avodart and is also available in combination with tamsulosin (Jalyn). Finasteride is marketed as Proscar (5-mg dose, for BPH) and Propecia (1-mg dose, approved for treating male pattern hair loss). None of these products is approved to prevent or reduce the risk of prostate cancer.
These labeling changes are the result of the FDA's review of two randomized studies, which evaluated the impact of 5-alpha reductase inhibitors (5-ARIs) in reducing the risk of prostate cancer when taken daily in 27,000 men aged about 50 years and older who were considered at an increased risk of developing prostate cancer. The Prostate Cancer Prevention Trial (PCPT) evaluated daily use of finasteride 5 mg versus placebo for 7 years, and the Reduction by Dutasteride of Prostate Cancer Events (REDUCE) trial evaluated daily use of dutasteride 0.5 mg versus placebo for 4 years. In those two studies, the risk of being diagnosed with prostate cancer was significantly reduced among those randomized to either of the two drugs, compared with those on placebo. But the reduction was because of a lower rate of lower-grade prostate cancers (with a Gleason score of 6 or lower). The risk of higher grade prostate cancers (with a Gleason score of 8-10) was increased among those who received one of the two 5-ARIs.
"This risk appears to be low, but health care professionals should be aware of this safety information, and weigh the known benefits against the potential risks when deciding to start or continue treatment with 5-ARIs in men," according to the statement.
Before prescribing one of these drugs, the statement advises that health care professionals "perform appropriate evaluation to rule out other urological conditions, including prostate cancer, [which] might mimic" benign prostatic hyperplasia (BPH).
The results of these studies were the focus of a meeting of the FDA's Oncologic Drugs Advisory Committee in December 2010. Citing the increases in high-grade prostate cancers among the treated men in these studies, the majority of the panel voted that the two drugs, when used as chemopreventive agents for reducing the risk of prostate cancer, had an unfavorable risk-benefit profile.
The full advisory is available at the FDA. Serious adverse events associated with 5-ARIs should be reported to MedWatch or by calling 800-332-1088.

Scrubbing Often During Nail Removal Reduces Infection Rates
LAS VEGAS – Preoperative scrubs before nail avulsion fail to reduce postoperative infection, recent data suggest.
However, studies have identified best practices for reducing bacterial counts – such as irrigating after nail plate avulsion though there is no evidence that the measures reduce postoperative infection rates.
"Every study that has looked at rates of colonization or recolonization after your scrub showed significant bacterial presence. As good as our scrubs are, they're probably not good enough," Dr. Nathaniel J. Jellinek said at the annual meeting of the American College of Mohs Surgery.
A recent study measured bacterial counts after a 7-minute surgical scrub and again after avulsion of the nail plate. The bacterial counts were essentially the same. "It's as if the surgical scrub didn't do any good," said Dr. Jellinek, who was not involved in the study (Dermatol. Surg. 2010;36:1258-65).
The investigators then irrigated the nail bed with saline, which reduced bacterial counts by 95%. That's "an easy thing to do intraoperatively that you might consider for your practice," said Dr. Jellinek of the department of dermatology at Brown University, Providence, R.I.
Studies published mainly in the podiatric and orthopedic literature show that postoperative infection rates are higher after nail surgery than after skin surgery. Rates of bacterial colonization before and after surgical preparation of nails make the term "sterile surgery" inaccurate for these procedures, which might better be considered clean-contaminated or even contaminated surgery, he said in an interview after his presentation.
Other studies have shown that applying alcohol and chlorhexidine may be superior to chloroxylenol and povidone-iodine to reduce bacterial counts before nail surgery. Bacterial persistence and recolonization also can be reduced by the use of bristled brushes, soaked gauze pads, scrubbing to the interdigital webs, and repeat scrubs.
"At this point, it's all hypothetical whether it decreases infection. But we know that infection rates are unacceptably high, so it can only help if you decrease the bacterial count," Dr. Jellinek said.
He has added multiple prophylactic measures to his practice, where he performs a lot of nail surgery.
First, Dr. Jellinek informs the patient that the nail is a dirty site, he reviews wound care, and educates the patient to pay attention to risk factors for infection and avoid putting fingers or toes in dirty places.
He recommends strict sterile preoperative and intraoperative techniques. A nurse or medical assistant should scrub the surgical area for several minutes. "We're talking not 10 or 30 seconds, but 2, 3, 5 minutes," he said.
The scrub should use multiple agents. He prefers using a bristle brush to scrub with chlorhexidine, gauze pads soaked in 70% isopropyl alcohol, and maybe even povidone-iodine paint. He lets all that sit, and applies a sterile glove over the digit, hand, or foot after the scrub.
During surgery, once the nail plate is avulsed, he recommends either performing a repeat scrub or at least irrigating the nail bed with sterile saline.
Dr. Jellinek said recent data have lowered his threshold for using prophylactic antibiotics. He has come to appreciate that nail infections may be caused by different organisms than those that cause most skin infections and require different antibiotics for treatment.
As a result, "I actually have very few nail infections, but I can't pinpoint which of those five or six things that I've done give me those results," he said.
Studies of prophylactic measures to avoid postoperative nail infections include:
- Preoperative skin and nail preparation of the foot: Comparison of the efficacy of 4 different methods in reducing bacterial load (J. Am. Acad. Dermatol. 2009;61:986-92).
- Chlorhexidine Provides Superior Skin Decontamination in Foot and Ankle Surgery: A Prospective Randomized Study (Clin. Orthop. Relat. Res. 2005;438:204-8).
- Preoperative Skin Preparation of the Foot and Ankle: Bristles and Alcohol Are Better (J. Bone Joint Surg. 2005;87:986-92).
- Efficacy of Surgical Preparation in Solutions in Foot and Ankle Surgery (J. Bone Joint Surg. 2005;87:980-5).
Dr. Jellinek said he had no relevant financial disclosures.

House Members Seek Recall of Formaldehyde-Containing Hair Straighteners
Ten members of Congress have written to the Food and Drug Administration asking that the agency recall several brands of hair-straightening products that they say contain formaldehyde.
In a May 6 letter to FDA Commissioner Margaret Hamburg, U.S. House of Representative members wrote that the Brazilian Blowout Solution and Acai Professional Smoothing Solution both contain formaldehyde, but the chemical is not listed on the product labels as an ingredient.
Rep. Earl Blumenauer (D-Ore.) had written to the agency last fall outlining complaints from Oregon hair stylists who had been experiencing acute reactions, such as nosebleeds, while working with the hair straighteners. The congressman also noted testing conducted by the Oregon Occupational Safety and Health Division and by Oregon Health and Science University found the two products contained between 6% and 12% formaldehyde.
He said that the federal Occupational Safety and Health Administration (OSHA) subsequently issued a hazard alert warning salons to steer clear of formaldehyde-based straighteners.
Formaldehyde has been recognized as a possible carcinogen and has been the subject of 47 complaints to the Environmental Working Group, members of Congress noted in the letter.
"It is clear that the FDA needs to take decisive action," they wrote.
In addition to a recall, they are seeking a warning for products that contain formaldehyde, an investigation into the companies that are claiming their products are formaldehyde free, and a review of whether the chemical should be banned from hair straighteners.
According to the May 6 letter to Dr. Hamburg, the FDA responded in late November to Rep. Blumenauer's initial letter and said that it was investigating whether the products were being marketed directly to consumers. "If so, failure to comply with the ingredient declaration requirement would constitute misbranding," responded the agency.

The Field Effect [editorial]

Scarring Alopecia in Black Women Still Not Understood
Despite being the most common pattern of scarring hair loss among African American women, central centrifugal cicatricial alopecia is still poorly understood, according to a report published online April 11 in Archives of Dermatology.
The etiology of and risk factors for the disorder have not been established. And although African American women commonly present with the condition, the exact prevalence remains unknown, said Dr. Angela Kyei and her associates at the Cleveland Clinic Institute of Dermatology and Plastic Surgery.
Central centrifugal cicatricial alopecia (CCCA) – previously known as hot comb alopecia or follicular degeneration syndrome – is a scarring hair loss centered on the vertex of the scalp and spreading peripherally, which is described almost exclusively in African American women. In the late 1960s it was linked to the use of hot combs, but since then almost every method of hair grooming in this population has been associated, albeit weakly, with the disorder. Few studies have examined other possible etiologies, such as immunologic, dermatologic, or genetic factors.
"Given the lack of epidemiologic data, the main goal of [our] study was to elucidate environmental as well as medical risk factors that may be associated with CCCA," the researchers wrote.
They administered questionnaires to 326 African American women attending two churches and a health fair in the Cleveland area. Sixteen of the women ended up being excluded from the analysis.
The questionnaires asked detailed information about family history of male- and female-pattern hair loss; personal medical history, including bacterial and fungal skin infections, autoimmune conditions, and hormonal dysregulation; and hair grooming methods used. The study subjects also underwent a scalp examination that included the grading of hair loss.
A total of 86 of the 310 women (28%) were judged to have central hair loss. Of these, 52 women – 17% of the total study population – had CCCA.
It appeared that hair grooming practices that cause traction, such as weaves and braids, may contribute to the development of CCCA, as women with the most severe central hair loss used these styles more frequently than did those without hair loss. "This has some clinical bearing because traction can clinically produce folliculitis of the scalp, which can cause scarring if this inflammation is prolonged," noted Dr. Kyei and her colleagues (Arch. Dermatol. 2011 April 11 [doi:10.1001/archdermatol.2011.66]).
After paying hundreds of dollars for such hair styling, women often maintain weaves and braids for weeks to months, so any reactive inflammation usually is prolonged, the investigators added.
However, "the relationship between chemical relaxer use and the development of CCCA continues to be murky," they noted. These products clearly weaken the hair shaft, which can cause breakage, but that does not necessarily lead to CCCA. "The fact that most African Americans use chemical relaxers in combination with braiding and other hair grooming practices makes it even more difficult to tease out a relationship," Dr. Kyei and her associates added.
It is difficult to find subjects who do not use chemical relaxers for comparison, since most African Americans begin the practice in childhood. In this study, 91% of the women reported using chemical relaxers, and began doing so at an average age of 10 years.
Nevertheless, "we feel that it is not unreasonable to assume that the scalp may absorb some of the caustic chemicals found in relaxers, which in time leads to damage of the scalp in the form of scarring," they wrote.
Although the prevalence of bacterial skin infections in these study subjects was only 11%, there was a significant elevation among women with CCCA, compared with women who did not have CCCA. The rate of acne also was elevated in affected subjects, but not to a significant degree. Thus, the researchers said that their study "demonstrates that inflammation in the form of bacterial infection and acne may also be contributing to the development of CCCA, a finding consistent with the histopathologic characteristics of this disease," which show a lymphocytic perifollicular infiltrate in its early stages.
In contrast, there was no such association with fungal infections of the scalp, ringworm, or vaginal yeast infections, which was "surprising given how prone this population is to fungal infection," they added.
"One of the most surprising findings ... was the overrepresentation of type 2 [diabetes mellitus] in those with CCCA," the authors noted. Again, the prevalence of type 2 diabetes was low, at 8%, but it was significantly elevated in women with CCCA, compared with those without CCCA.
"These are important data that need further study because CCCA may be a marker of metabolic dysfunction and, when present, can prompt clinicians to do further testing for diabetes mellitus," Dr. Kyei and her colleagues wrote.
Only 9% of the study subjects had thyroid abnormalities, and three-fourths of them had no or minimal hair loss.
A history of male-pattern baldness in the maternal grandfather was found to be a risk factor for CCCA, which suggests that genetics may play a role.
Hormonal dysregulation did not appear to be associated with development of CCCA. Neither were scarring disorders, since only 6% of the subjects reported a history of keloids, and the rate was no higher in women with CCCA than in those without CCCA.
Similarly, there were relatively high prevalences of seborrheic dermatitis (24%), eczema (13%), and contact dermatitis from chemical relaxers (9%), as would be expected in an African American population. However, these conditions were unrelated to CCCA.
This study was supported in part by the North American Hair Research Society and Procter & Gamble. No financial conflicts of interest were reported.

It appeared that hair grooming practices that cause traction, such as weaves and braids, may contribute to the development of CCCA, as women with the most severe central hair loss used these styles more frequently than did those without hair loss. "This has some clinical bearing because traction can clinically produce folliculitis of the scalp, which can cause scarring if this inflammation is prolonged," noted Dr. Kyei and her colleagues (Arch. Dermatol. 2011 April 11 [doi:10.1001/archdermatol.2011.66]).
After paying hundreds of dollars for such hair styling, women often maintain weaves and braids for weeks to months, so any reactive inflammation usually is prolonged, the investigators added.
However, "the relationship between chemical relaxer use and the development of CCCA continues to be murky," they noted. These products clearly weaken the hair shaft, which can cause breakage, but that does not necessarily lead to CCCA. "The fact that most African Americans use chemical relaxers in combination with braiding and other hair grooming practices makes it even more difficult to tease out a relationship," Dr. Kyei and her associates added.
It is difficult to find subjects who do not use chemical relaxers for comparison, since most African Americans begin the practice in childhood. In this study, 91% of the women reported using chemical relaxers, and began doing so at an average age of 10 years.
Nevertheless, "we feel that it is not unreasonable to assume that the scalp may absorb some of the caustic chemicals found in relaxers, which in time leads to damage of the scalp in the form of scarring," they wrote.
Although the prevalence of bacterial skin infections in these study subjects was only 11%, there was a significant elevation among women with CCCA, compared with women who did not have CCCA. The rate of acne also was elevated in affected subjects, but not to a significant degree. Thus, the researchers said that their study "demonstrates that inflammation in the form of bacterial infection and acne may also be contributing to the development of CCCA, a finding consistent with the histopathologic characteristics of this disease," which show a lymphocytic perifollicular infiltrate in its early stages.
In contrast, there was no such association with fungal infections of the scalp, ringworm, or vaginal yeast infections, which was "surprising given how prone this population is to fungal infection," they added.
"One of the most surprising findings ... was the overrepresentation of type 2 [diabetes mellitus] in those with CCCA," the authors noted. Again, the prevalence of type 2 diabetes was low, at 8%, but it was significantly elevated in women with CCCA, compared with those without CCCA.
"These are important data that need further study because CCCA may be a marker of metabolic dysfunction and, when present, can prompt clinicians to do further testing for diabetes mellitus," Dr. Kyei and her colleagues wrote.
Only 9% of the study subjects had thyroid abnormalities, and three-fourths of them had no or minimal hair loss.
A history of male-pattern baldness in the maternal grandfather was found to be a risk factor for CCCA, which suggests that genetics may play a role.
Hormonal dysregulation did not appear to be associated with development of CCCA. Neither were scarring disorders, since only 6% of the subjects reported a history of keloids, and the rate was no higher in women with CCCA than in those without CCCA.
Similarly, there were relatively high prevalences of seborrheic dermatitis (24%), eczema (13%), and contact dermatitis from chemical relaxers (9%), as would be expected in an African American population. However, these conditions were unrelated to CCCA.

Despite being the most common pattern of scarring hair loss among African American women, central centrifugal cicatricial alopecia is still poorly understood, according to a report published online April 11 in Archives of Dermatology.
The etiology of and risk factors for the disorder have not been established. And although African American women commonly present with the condition, the exact prevalence remains unknown, said Dr. Angela Kyei and her associates at the Cleveland Clinic Institute of Dermatology and Plastic Surgery.
Central centrifugal cicatricial alopecia (CCCA) – previously known as hot comb alopecia or follicular degeneration syndrome – is a scarring hair loss centered on the vertex of the scalp and spreading peripherally, which is described almost exclusively in African American women. In the late 1960s it was linked to the use of hot combs, but since then almost every method of hair grooming in this population has been associated, albeit weakly, with the disorder. Few studies have examined other possible etiologies, such as immunologic, dermatologic, or genetic factors.
"Given the lack of epidemiologic data, the main goal of [our] study was to elucidate environmental as well as medical risk factors that may be associated with CCCA," the researchers wrote.
They administered questionnaires to 326 African American women attending two churches and a health fair in the Cleveland area. Sixteen of the women ended up being excluded from the analysis.
The questionnaires asked detailed information about family history of male- and female-pattern hair loss; personal medical history, including bacterial and fungal skin infections, autoimmune conditions, and hormonal dysregulation; and hair grooming methods used. The study subjects also underwent a scalp examination that included the grading of hair loss.
A total of 86 of the 310 women (28%) were judged to have central hair loss. Of these, 52 women – 17% of the total study population – had CCCA.

Picture Review: Dermoscopy Distinguishes Hair Disorders
ORLANDO - Dermoscopy can help with the diagnosis and management of hair and scale disorders.
In some instances, dermoscopy very rapidly reveal a characteristic sign of a hair or scalp condition. In presentations where dermoscopy only narrows down your differential diagnosis, further work-up with histology might be required, said Dr. Antonella Tosti, professor of clinical dermatology at the University of Miami.
How well do you know your dermoscopy diagnoses?

"You also see single hairs coming out from the scalp," Dr. Tosti said. Most hair disorders feature a high number of single hairs. A normal vascular pattern presents as interfollicular red loops and arborizing red lines. |
|
Psoriasis. Twisted, coiled loops are a sign of scalp psoriasis. Folliculitis decalvans is the only other scalp condition with a similar loop presentation. If you observe white scales, use high-magnification dermoscopy to look at the vessels before diagnosing psoriasis. White scales can also be seen in cicatricial alopecias such as lupus erythematosus and lichen planopilaris. "So you may need to take a biopsy when patient presents with wide, white scales. It's not always psoriasis," Dr. Tosti said. |
|
Alopecia areata. Alopecia areata and androgenetic alopecia each will feature yellow dots that correspond to follicular openings. "How often you see the yellow dots depends on the patients. They are seen often in [whites] and less commonly seen in darker-skinned patients," Dr. Tosti said. Hair diameter variability, a sign of androgenetic alopecia, can help you to distinguish these conditions. More than 20% variability in shaft thickness and an increase in the number of thinner hairs with advanced disease are diagnostic. "My suggestion is always use your dermatoscope when women complain of hair loss," Dr. Tosti said. "It is an easy and quick way to distinguish androgenetic alopecia." |
|
Discoid lupus erythematosus. A follicular red dot pattern is characteristic of this condition on dermoscopy. An atrophic epidermis can be seen in active lesions. The red dots are important to recognize because, if treated, hair can regrow in the affected area. "Make the diagnosis early and treat the patient immediately," Dr. Tosti said. Also, the red dot pattern will help you to distinguish this disorder from other conditions that can cause cicatricial alopecia. |

Traction alopecia. Hair casts are a useful dermoscopy clue for this condition. "You can see them immediately," Dr. Tosti said. "Hair casts are also useful in African Americans if their hairstyle is associated with traction, even if they don't have alopecia. Sometimes they will deny a traction hairstyle." |
|
Tinea capitis. Dermoscopy facilitates this diagnosis. Look for comma-shaped hairs, a very specific sign seen in both ectothrix and endothrix T. capitis infections. "This is something you should look for in children. It's very fast," Dr. Tosti said. The comma hairs will be more numerous in recent infections, she added. |
|
Monilethrix. Dermoscopy can help you diagnose this condition very, very fast, Dr. Tosti said. The condition features beading of the hair shafts. The autosomal recessive form of monilethrix will appear much more severe on dermoscopy (J. Invest. Dermatol. 2006;126:1292-6). |
Dr. Tosti said that she had no relevant disclosures.
