A new approach to actinic folliculitis: prophylactic narrowband ultraviolet B phototherapy.

BACKGROUND: We have observed an increasing number of patients referred to the Scottish Photobiology Service (SPS), who were later diagnosed with actinic folliculitis (AF) and had positive phototesting results. Treatment options for AF are limited, with only a few reports in the literature. The use of prophylactic narrowband ultraviolet B (NB-UVB) phototherapy for AF has not previously been described, and we report on this for the first time. AIM: To analyse the clinical characteristics, phototesting results and responses to treatment for patients with AF diagnosed by the SPS. METHODS: We undertook a retrospective review over 10 years of all case notes of patients who were assessed and diagnosed with AF through the SPS, based at the Photobiology Unit, Dundee, UK. RESULTS: All 10 patients were women. Mean age of onset was 25 years and mean time to referral for investigation was 7 years. The commonest site involved was the face, with the main clinical feature being monomorphic pustules appearing after sunlight exposure. The eruption could be provoked with iterative doses of broadband UVA irradiation in five patients. All patients were offered photoprotective advice and prophylactic NB-UVB phototherapy. Five patients proceeded with phototherapy; four of these completed the desensitization course and all four reported either a delay in symptom onset or total prevention of rash induction, with complete efficacy of desensitization maintained for 3 years in one patient. CONCLUSION: We demonstrate the successful use of UVA provocation testing as a diagnostic tool in AF. Additionally, we recommend the use of prophylactic NB-UVB phototherapy in AF as an effective and well-tolerated approach.

Treatment of folliculitis decalvans using intensity-modulated radiation via tomotherapy.

BACKGROUND: Folliculitis decalvans (FD) is a form of primary neutrophilic scarring alopecia that is characterized clinically by chronic suppurative folliculitis and often associated with pruritus or even pain. Treatment of FD is often difficult. Herein, we report a case of recalcitrant and painful folliculitis decalvans refractory to antibiotic and anti-inflammatory therapies, which was successfully treated by intensity-modulated radiotherapy (IMRT) in order to irreversibly eliminate hair follicles that prove to be one etiological trigger. CASE PRESENTATION: A 45-year-old male patient with a refractory FD presented with a crusting suppurative folliculitis and atrophic scarring patches on the scalp associated with pain and pruritus. We attempted relief of symptoms by reducing scalp inflammation and eliminating hair follicles through radiation. We delivered 11.0 Gy in two radiation series using tomotherapy, 5.0 Gy in 5 equivalent fractions as a first radiation course. The symptoms markedly decreased but did not totally disappear. Therefore, we delivered a second radiation series 4 months later with an additional 6 Gy. This led to almost complete epilation on the scalp and abolished pain and pruritus on the capillitium. The patient was regularly followed up until 26 months after radiotherapy. Draining lesions or exudation did not recur. He only experienced discrete hair regrowth in the occipital region with folliculitis 12 months after radiotherapy. These residual lesions are currently treated with laser epilation therapy. CONCLUSION: A radical approach to eliminating hair follicles by repeated radiation therapy may induce lasting relief of symptoms in chronic suppurative FD associated with persistent trichodynia.

Long-term remission of folliculitis decalvans after treatment with the long-pulsed Nd:YAG laser.

Folliculitis decalvans (FD) is a rare inflammatory scalp disorder presenting with tufted folliculitis, follicular papules and pustules, progressing to cicatricial alopecia. Current treatments mainly consist of antibiotic and immunomodulatory therapies and are often disappointing. FD has previously shown to respond to treatment with neodymium:yttrium aluminium garnet (Nd:YAG) laser in one case. We present a case of recalcitrant FD, successfully treated with a long-pulsed Nd:YAG laser.

Recalcitrant eosinophilic pustular folliculitis of Ofuji with palmoplantar pustulosis: dramatic response to narrowband UVB phototherapy.

Eosinophilic pustular folliculitis of Ofuji is a recalcitrant disease typified by non-infective eosinophilic spongiosis involving the infundibular region of the hair follicle. We present a case of a 49-year-old Chinese man with known palmoplantar pustulosis and acrodermatitis continua of Hallopeau which was promptly resolved with methotrexate therapy. He returned with an erythematous papulopustular eruption with coalescence to annular plaques, occurring over the face, chest and back with active palmoplantar pustulation. Histology from skin biopsy of the palmar lesion was in keeping with palmoplantar psoriasis, while biopsy of the facial and truncal lesions revealed florid perifollicular eosinophilic congregation diagnostic of eosinophilic pustular folliculitis of Ofuji. Indomethacin was initiated with partial improvement of lesions with cyclical flares. A trial of narrowband ultraviolet-B phototherapy at a frequency of thrice weekly achieved sustained clearance of both eosinophilic pustular folliculitis and palmoplantar lesions. Indomethacin was tailed down and eventually discontinued with maintenance of narrowband ultraviolet-B therapy; this achieved successful control of the disease.

[Pseudofolliculitis barbae]. / Pseudofoliculitis de la barba.

Pseudofolliculitis barbae is a chronic, irritating, and potentially disfiguring condition that develops as a result of attempts to eliminate hair from the beard area, usually by shaving. It is difficult to determine the incidence of the disorder, but some studies report that it affects up to 1 of every 5 caucasian individuals and that it is much more common in black persons. Clinically it is characterized by the appearance of inflammatory papules and pustules. Once pseudofolliculitis has become established, treatment consists of avoiding shaving and the use of medical treatment similar to that used in acne. However, the long-term result is much more dependent on prevention through a correct shaving technique. In severe cases or when a definitive solution is sought, the treatment of choice is photodepilation.

Treatment of folliculitis with monochromatic excimer light (308 nm).

BACKGROUND/AIMS: 308-nm excimer light has been reported to be safe and effective in the treatment of chronic skin diseases. The aim of the study was to prove the efficacy of 308-nm monochromatic excimer light in the treatment of recalcitrant and antibiotic-resistant folliculitis. METHODS: Eight patients affected with folliculitis were enrolled and treated twice weekly with the 308-nm excimer light. The follow-up was 12 weeks from the end of the treatment. RESULTS: A mean number of 13 sessions (range 10-20) was performed with increasing dosage according to the patient's photo-type and response. Remission, in terms of number and infiltration of papulopustular elements, was achieved in all patients after 4-16 therapeutic sessions. At the end of the follow-up period, recurrence of folliculitis was observed in 2 patients. CONCLUSIONS: These results suggest that the 308-nm excimer light is a valid therapeutic option for the treatment of resistant forms of folliculitis especially in difficult-to-treat areas.

Low-fluence 1,064-nm laser hair reduction for pseudofolliculitis barbae in skin types IV, V, and VI.

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/cm(2)) 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/cm(2). 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<.01). There was a mean reduction of 59.5% in dyspigmentation (p<.03), 91.2% in papule count (p<.01), and 75.6% in cobblestoning (p<.02). Patients reported 1 out of 10 on both adverse effects scales. CONCLUSION: Low-fluence 1,064-nm laser treatment achieved significant temporary reduction in PFB. Subjects noted minimal pain without topical anesthesia.

The medical and surgical therapy of pseudofolliculitis barbae.

Pseudofolliculitis barbae (PFB) is a common, chronic, inflammatory skin disorder seen mainly in individuals with curly hair. This condition is seen most frequently in black men who shave their beards but may also be seen in women of all races who wax or shave the axillary and pubic skin. The etiology of PFB is multifactorial, and heretofore a cure has been considered impossible for those desiring a clean-shaven face. The following article serves to discuss the current medical and surgical therapies available for this condition. Medical treatments for this condition include various combinations of topical antibiotics, corticosteroids, and retinoids. In the surgical arena, laser therapy has revolutionized the treatment of PFB and has enabled cure for the first time for those plagued by this disorder and for whom a beardless face is acceptable.

The role of radiation treatment in the management of eosinophilic pustular folliculitis.

We are reporting a rare chronic irritating, incapacitating skin condition that can be controlled by radiation treatment. We would like to add this case to the world literature.

Eosinophilic pustular folliculitis (Ofuji's disease): indomethacin as a first choice of treatment.

Eosinophilic pustular folliculitis (EPF) is characterized by erythematous patches of large follicular papules and pustules involving mainly the face. Although various treatments have been attempted for EPF, including systemic and topical steroid, diaphenylsulphone, colchicine, minocycline as well as UVB phototherapy, there is no consensus on the first choice of treatment. We report a typical case and summarize 25 patients with EPF treated in our hospital between 1978 and 1998. Indomethacin was most frequently used (12/25) and showed clinical improvement in the majority of the cases (11/12). The effect of indomethacin was usually observed within 1--2 weeks after initiation of treatment. Decrease of peripheral blood eosinophils accompanied the clinical improvement. Thus, indomethacin should be considered as a first choice of treatment for EPF.

Laser treatment of atrophoderma vermiculata.

Atrophoderma vermiculata is a rare genodermatosis with usual onset in childhood, characterized by a "honey-combed" reticular atrophy of the cheeks. The course is generally slow, with progressive worsening. We report successful treatment of 2 patients by means of the carbon dioxide and 585 nm pulsed dye lasers.

Treatment of pseudofolliculitis barbae with the diode laser.

Pseudofolliculitis barbae is a common skin disorder of the beard area that is characterized by the presence of inflammatory follicular papules due to terminal hair shafts re-entering the epidermis. Postinflammatory hyperpigmentation and scarring often occur with pseudofolliculitis barbae. Such skin changes can lead to cosmetic disfigurement and be of great concern to the patient. We report a case of pseudofolliculitis barbae and hirsutism with associated postinflammatory hyperpigmentation in an African-American woman who was effectively treated with the diode laser.

HIV-positive patients differ from HIV-negative patients in indications for and type of UV therapy used.

BACKGROUND: Treatments using UV, UVB, or oral psoralen and UVA (PUVA) have been advocated for the care of HIV-infected persons with skin diseases. Concerns about the safety of these treatments exist. OBJECTIVE: We attempted to determine the characteristics of HIV infected persons receiving UV therapy and establish the reasons for and type of treatment administered. METHODS: During two 2-week periods, we prospectively ascertained basic information on all patients treated at 40 phototherapy clinics and detailed clinical information on patients known to be infected with HIV. RESULTS: We identified 3716 persons receiving UV therapy, including 311 known to be infected with HIV. When compared with patients not known to be infected with HIV, HIV-positive patients were significantly more likely to be treated with UVB rather than PUVA and were more likely to be treated for pruritic conditions rather than psoriasis. CONCLUSION: There were great variations in the relative reliance on UVB and PUVA among centers. There appears to be no agreement as to which type of UV therapy is optimal for patients infected with HIV. Most patients known to the treating clinician to be HIV positive are in the advanced stages of HIV disease. The number of persons with less advanced HIV disease receiving treatment remains unquantified but may be even more clinically important.

HIV-associated eosinophilic pustular folliculitis: successful treatment of a Japanese patient with UVB phototherapy.

We report the successful treatment with ultraviolet B phototherapy of a patient with HIV-associated eosinophilic pustular folliculitis. We were able to observe the clinical and therapeutic course for about one year and three months. This 35-year-old homosexual Japanese man presented with disseminated, discrete, follicular, erythematous papules with intense pruritus over his face, neck, chest wall, and upper back. Initially, the eruption responded to therapy with topical or oral indomethacin and oral H1 antihistamine. However, the eruption was highly prone to recurrence, and it gradually failed to respond to these therapies. The eruption became chronic and persistent and manifested the excoriated, prurigo-like nodules that are typical of reported pruritic papular eruption, suggesting that this skin disease and HIV-associated eosinophilic pustular folliculitis are two forms of the same disease entity. UVB phototherapy in small doses was very effective for the persistent eruption, and no recurrence of the eruption was noted during or since the six-month maintenance therapy (once a week at a dose equivalent to 0.75 of the minimal erythema dose) (9 months total). No unfavorable side effects have been observed during or after the UVB phototherapy (cumulative UVB doses of 2,320 mJ/cm2).

UVB phototherapy is an effective treatment for pruritus in patients infected with HIV.

BACKGROUND: Pruritus in patients positive for HIV may be debilitating. OBJECTIVE: Our purpose was to evaluate the efficacy of UVB therapy in the treatment of pruritus in patients positive for HIV. METHODS: Twenty-one male HIV-positive patients with intractable pruritus (14 with eosinophilic folliculitis and 7 with primary pruritus) were treated three times weekly with UVB phototherapy. Pruritus was quantified with use of a subjective score of 0 (none) to 10 (severe). RESULTS: Mean CD4 counts at the initiation of therapy were 91.0 +/- 31.9 cells/microliter. Pruritus scores before and after treatment were 8.6 +/- 0.4 and 2.2 +/- 0.5, respectively (p < 0.001). The mean number of treatments to achieve maximal improvement was 20.7 +/- 2.3, with a cumulative UVB dose of 3399.1 +/- 597.4 mJ/cm2. No significant difference was found between the group with eosinophilic folliculitis and the group with primary pruritus. CONCLUSION: UVB phototherapy can produce significant relief of pruritus and improvement in the quality of life in patients positive for HIV.
