Low-fluence 1,064-nm laser hair reduction for Pseudofolliculitis Barbae in skin types IV, V, and VI.
Dermatologic Surgery, 2008Co-Authors: Rafael Schulze, Doug Winstanley, Ken. J. Meehan, Antonia Lopez, Kasina Sweeney, William Apruzzese, E. Victor RossAbstract:PURPOSE To evaluate the efficacy of a 1,064-nm neodymium-doped yttrium aluminium garnet (Nd:YAG) laser using lower than traditional fluences (22–40 J/cm2) for treatment of Pseudofolliculitis Barbae (PFB). METHODS Twenty-two patients with PFB refractory to conservative therapy received five weekly treatments over the anterior neck using a 1,064-nm Nd:YAG laser at 12 J/cm2. Pulse duration was 20 ms with 10 mm spot size. Topical anesthesia was not used. Treatments were completed 15 minutes after patient arrival. Patients presented for 2- and 4-week follow-up. Ten evaluators used a Global Assessment Scale (GAS) to assess dyspigmentation, papule counts, and cobblestoning by comparing baseline to 4-week follow-up visit photographs. Hair and papule counts were performed on five patients and compared with the GAS. Investigators recorded adverse effects using a visual analog and side effects scale. RESULTS Eleven patients demonstrated 83% improvement on the GAS (p

Lasers in the military for cutaneous disease and wound healing.
Dermatologic Clinics, 2005Co-Authors: E. Victor Ross, N. ChhiengAbstract:The clinical laser experience of military dermatologists mirrors that of their civilian counterparts; however, there are applications for lasers in dermatology in which there is special military relevance. These range from treatment of common diseases such as Pseudofolliculitis Barbae to noninvasive identification of shrapnel injuries on the battlefield using novel laser-based diagnostic techniques. Although some applications in this report are experimental, emerging technologies should allow for their clinical or field implementation in the near future.

Modified superlong pulse 810 nm diode laser in the treatment of Pseudofolliculitis Barbae in skin types V and VI.
Dermatologic Surgery, 2005Co-Authors: Eric P. Smith, Doug Winstanley, E. Victor RossAbstract:Background Laser hair removal is a well-established therapy for Pseudofolliculitis Barbae, but there have been few studies on the use of a very-long-pulse 810 nm diode laser for this condition. Objective To determine the efficacy and tolerability of a modified 810 nm superlong-pulse diode laser (Palomar Medical, Burlington, MA, USA) in the treatment of Pseudofolliculitis Barbae (PFB) in subjects with type V and VI skin. Methods Thirteen patients were treated three times at 2-week intervals on one side of their neck with varying fluences. They were evaluated for (1) reduction of shaving bumps and (2) pain tolerance on the treated versus the untreated side. Results There was a statistically significant improvement in shaving bumps. The treatment side showed a baseline PFB lesion count of 22.5 (±20 SD), which decreased to a mean of 5 (±5 SD) (p < .05). The control baseline mean count was 27.6 (±22 SD) and at the end of the study was 15 (±12 SD) (p= .13). Pain was rated at 2.5 of 10 for subjects treated both with and without anesthetic. The margin of safety was greater in type V compared with type VI skin. Conclusion A modified 810 nm superlong-pulse diode laser is both effective and well tolerated in the reduction of shaving bumps, especially in patients with type V skin. THE LASER WAS LOANED TO THE US NAVY FOR USE IN THIS STUDY.

Treatment of Pseudofolliculitis Barbae in very dark skin with a long pulse Nd:YAG laser.
Journal of The National Medical Association, 2002Co-Authors: E. Victor Ross, Linda M. Cooke, Kristen A. Overstreet, Greg D. Buttolph, Mark A. BlairAbstract:BACKGROUND: Pseudofolliculitis Barbae affects some individuals with coarse curly hair. Currently available treatment modalities are often ineffective. In some studies, lasers have been shown to be potentially helpful in mitigating disease severity by reducing the number and/or thickness of hair shafts. METHODS: This was a side-by-side interventional study conducted at a military tertiary medical facility. The study group included 26 patients (skin types IV, V, and VI) referred from primary care physicians with a diagnosis of Pseudofolliculitis Barbae refractory to medical therapy. A neodymium YAG laser was used to treat one half of the neck. One month later, shaving bumps were counted and compared to their preoperative levels on both sides. RESULTS: Mean postoperative papule counts were 11.6 +/- 6 (SD) and 30.1 +/- 19 (SD) on the treated side and untreated sides, respectively. CONCLUSION: Neodymium YAG laser treatment represents a safe and effective option for reducing papule formation in patients with Pseudofolliculitis Barbae.

Treatment of Pseudofolliculitis Barbae in skin types IV, V, and VI with a long-pulsed neodymium:yttrium aluminum garnet laser.
Journal of The American Academy of Dermatology, 2002Co-Authors: E. Victor Ross, Linda M. Cooke, Kristen A. Overstreet, Brad S. Graham, Anthony Louis Timko, David J. BarnetteAbstract:BACKGROUND: Pseudofolliculitis Barbae affects a large number of individuals with coarse curly hair, and present treatment options are suboptimal. OBJECTIVE: We evaluated the safety and efficacy of a long-pulsed neodymium:yttrium aluminum garnet (Nd:YAG) laser in the treatment of Pseudofolliculitis Barbae. METHODS: This was a two-phase observational study conducted at a military tertiary medical facility. The study group included 37 patients (skin types IV, V, and VI) referred from primary care physicians with a diagnosis of Pseudofolliculitis Barbae refractory to conservative therapy. In phase I, one treatment with a Nd:YAG laser was performed on a tattooed area of the thigh with 3 light doses. Epidermal tolerance was evaluated, and hair counts were performed 3 months after treatment for each light dose. In phase II, the highest dose tolerated by the epidermis from phase I was applied to a small submental region of skin with an adjacent site as a control. Subsequently, papule counts were performed 90 days after treatment in the laser-irradiated and control areas. RESULTS: Phase I: When normalized for controls, there was 33%, 43%, and 40% hair reduction on the thigh for the 50, 80, and 100 J/cm(2) fluences, respectively, after 90 days. Overall, the highest doses tolerated by the epidermis were 50, 100, and 100 J/cm(2) for type VI, V, and IV skin, respectively. Phase II: Mean papule counts after 90 days were 6.95 and 1.0 for the control and treatment sites, respectively. CONCLUSION: Nd:YAG laser treatment may represent a safe and effective option for reducing hair and subsequent papule formation in patients with Pseudofolliculitis Barbae.

Treatment of Pseudofolliculitis Barbae Using the Long‐Pulse Nd:YAG Laser on Skin Types V and VI
Dermatologic Surgery, 2003Co-Authors: Seymour M. Weaver, Emelou C. SagaralAbstract:Background. Pseudofolliculitis Barbae (PFB) is a foreign body inflammatory condition that is caused by in-grown hairs of the face and body. An effective treatment to alleviate this condition without the risk of side effects has yet to be found. Objective. The objective of this study was to evaluate the Lyra 1064-nm long-pulse ND:YAG laser in the treatment of PFB on skin types V and VI. Methods. Twenty subjects (12 males and 8 females) were given two treatments approximately 3 to 4 weeks apart and were assessed by objective papule/pustule and hair counts at 1, 2, and 3 months after final treatment. Laser treatments with the Lyra Nd:YAG laser were applied onto 2×2-cm regions on the upper and lower mandible and neck regions. Contralateral controls were used to assess overall effectiveness. Subjective evaluations were also obtained from both subjects and investigators. Assessments of any abnormal side effects caused by laser treatment, including dyspigmentation and/or scarring, were also evaluated. Results. A reduction in the quantity of papules/pustules and hairs when compared with baseline data was statistically significant for treatment of PFB in the mandibular and neck regions at the 1-, 2-, and 3-month follow-up evaluations. Subject evaluations ranged from satisfied to very satisfied. Side effects included transient hyperpigmentation, transient hypopigmentation, mild erythema, and itching. Conclusions. The use of the 1064-nm long-pulse Nd:YAG laser for the treatment and management of PFB on skin types V and VI is both safe and effective, with positive results lasting for up for to 3 months after two treatments.

Enhancing the care and treatment of skin of color, part 1: The broad scope of pigmentary disorders.
Cutis, 2005Co-Authors: Susan C. TaylorAbstract:Abstract Scientific research and technologies related to skin pigmentation and dyschromias, which are often key skin concerns for patients of color, have led to recent developments in skin care and treatment. Differences and similarities between skin of color and white skin and current issues in the treatment of ethnic skin are reviewed. Recent research findings, such as the elucidation of the protease-activated receptor 2 (PAR-2) pathway and its role in pigmentation, and areas for further investigation, such as the pathogenesis of Pseudofolliculitis Barbae (PFB), also are discussed. Awareness of this information within the wider community of dermatologists, primary healthcare providers, and the media will help to accomplish the objective of stimulating new prospective research.

Twice-daily applications of benzoyl peroxide 5%/clindamycin 1% gel versus vehicle in the treatment of Pseudofolliculitis Barbae.
Cutis, 2004Co-Authors: Fran E Cook-bolden, Rebat M. Halder, Alicia Barba, Susan C. TaylorAbstract:: Pseudofolliculitis Barbae (PFB) is an inflammatory disorder characterized by the formation of papules, pustules, and hyperpigmentation as a result of ingrown hairs. It is estimated that PFB affects 45% to 83% of black men who shave regularly. In this multicenter, double-blind pilot study, men with 16 to 100 combined papules and pustules on the face and neck were randomized to receive twice-daily benzoyl peroxide 5%/ clindamycin 1% (BP/C) gel (BenzaClin)(n = 47) or vehicle (n = 41) for 10 weeks. Sixty-eight (77.3%) of the participants were black. All patients were required to shave at least twice a week and to use a standardized shaving regimen throughout the study. Clinical evaluations were performed at 2-week intervals. The primary efficacy parameter was the percentage change from baseline in lesion counts. At weeks 2, 4, and 6, mean percentage reductions from baseline in combined papule and pustule counts were significantly greater with BP/C gel compared with vehicle (P < or = .029). Treatment differences in favor of active therapy were more pronounced in the subpopulations of black patients, with least squares mean percentage reductions in papule and pustule counts ranging from 38.2% at week 2 to 63.9% at week 10. Study medication was well tolerated. These positive findings warrant further investigation of BP/C gel in the treatment of patients with PFB.

Defining Pseudofolliculitis Barbae in 2001: A review of the literature and current trends
Journal of The American Academy of Dermatology, 2002Co-Authors: Patricia K. Perry, Fran E Cook-bolden, Zakia Rahman, Elena Jones, Susan C. TaylorAbstract:Abstract Pseudofolliculitis Barbae (PFB) is a chronic inflammatory and potentially disfiguring condition most often seen in men and women of African American and Hispanic origin who have tightly curled hair and who shave or tweeze hairs frequently. The etiology is multifactorial. The shape of the hair follicle, hair cuticle, and the direction of hair growth each play a role in the inflammatory response once the hair is shaven or plucked and left to grow. This reaction often produces painful, pruritic, and sometimes hyperpigmented papules in the beard distribution. The result is an unappealing cosmetic appearance, often with emotionally distressing consequences for affected individuals. The diagnosis is made clinically. Currently, prevention and early intervention are the mainstays of therapy. Many treatment options are available; however, none has been completely curative. In this review, the history, incidence, pathogenesis, clinical manifestations, dermatopathology, prevention, and treatment of PFB, including the most current surgical options, will be discussed. In addition, new data on patients with PFB from the Skin of Color Center will be presented. (J Am Acad Dermatol 2002;46:S113-9.)
