Keratosis follicularis spinulosa decalvans and acne keloidalis nuchae.

A 27-year-old man presented with a 10-year history of scarring alopecia on the vertex of the scalp associated with follicular crusting and pustule formation, and a papular eruption on the posterior neck. Additionally, there was keratosis pilaris on the cheeks, eyebrows and thighs. Histology from the vertex showed scarring with a mixed perifollicular inflammatory infiltrate and foci of acute suppurative folliculitis. With clinical correlation, the diagnosis of keratosis follicularis spinulosa decalvans and concurrent acne keloidalis nuchae was made. The association of keratosis follicularis spinulosa decalvans with acne keloidalis nuchae has not previously been described. The patient responded to treatment with oral isotretinoin 20 mg (0.25 mg/kg) daily for 12 months.

Hair casts due to a deodorant spray.

A 7-year-old girl presented with itching and greyish-white sleeve-like structures in her hair. After ruling out other possible causes for the symptoms, such as nits and dandruff, it was determined that the patient was affected by hair casts. These are small cylindrical structures resembling louse eggs that encircle individual scalp hairs and are easily movable along the hair shafts. It was concluded that she had induced the condition through misuse of a deodorant body spray. Scanning electron microscopy combined with electron dispersive X-ray analysis (X-ray microanalysis) of the hair casts showed the chemical nature of the structures. Some elements present in the composition of the ingredients of the deodorant spray, such as aluminium, chlorine, silicon, magnesium and carbon, were also present in this uncommon type of hair casts.

Head lice prevalence in primary schools in Victoria, Australia.

OBJECTIVES: To determine the prevalence of and assess risk factors associated with head lice infections (pediculosis) in children from government primary schools in Victoria, Australia. METHODS: Between May and October 2001, children were selected by clustered random sampling of schools and classes, then examined for head lice using hair conditioner and a fine-toothed head lice comb. There were 1838 children screened from 16 primary schools. Risk factors evaluated included metropolitan or rural residence, school class, gender and hair length. RESULTS: Thirteen percent of children (239/1838) had an active infection (95% CI, 10.9-15.1) and 3.3% (61/1838) had an inactive infection (95% CI, 2.0-4.6). Prevalence of active pediculosis varied between schools from 0 to 28%. Our screening identified no more than one case per class in the majority of classes screened (58.5%). Females were 2.2 times more likely to have active infection than males (95% CI [1.7,2.9]) and there was no significant difference for the other risk factors investigated. CONCLUSIONS: Our study demonstrated the prevalence of head lice varied across Victoria and showed that risk factors commonly attributed to head lice infections did not hold true. Our findings support the premise that traditional ad hoc mass school-based screening may not be the best use of resources when controlling head lice. We suggest a more pragmatic community-based approach.

Giant cell arteritis presenting with scalp necrosis--the timing of temporal artery biopsy?

Scalp necrosis in patients presenting with clinical features suggestive of giant cell arteritis is rare. The immediate concern is that temporal artery biopsy might further compromise scalp circulation. We report a case of extensive scalp necrosis caused by giant cell arteritis. Temporal artery biopsy performed after 14 days was not associated with any significant damage and still provided florid evidence of the disease. Rapid and complete scalp healing was achieved with aggressive treatment.

Efficacy of different concentrations of ciclopirox shampoo for the treatment of seborrheic dermatitis of the scalp: results of a randomized, double-blind, vehicle-controlled trial.

BACKGROUND: Seborrheic dermatitis is a common inflammatory skin disorder affecting 1-3% of the population. It is thought to be linked to dandruff via a common etiology, yeasts of the genus Malassezia. Ciclopirox is a broad-spectrum, hydroxypyridone-derived, synthetic antifungal agent with anti-inflammatory properties. METHODS: A total of 203 patients were enrolled in this vehicle-controlled, double-blind, randomized study designed to compare vehicle with three different concentrations of ciclopirox shampoo: 0.1%, 0.3% and 1%, with each applied twice a week. The main efficacy parameters were based on 6-point ordinal scales describing the disease's signs and symptoms (scaling, inflammation and itching), global status of disease, and global change in disease. RESULTS: A tendency towards improvement of the sum score from baseline was found in all ciclopirox treatment groups. The most pronounced improvement was found in the ciclopirox 1% group, which changed from a baseline sum score of 8.3 to 4.4 at the end of the 4-week study period (P-value vs. vehicle 0.0372). In addition, the therapeutic index showed increasing efficacy with the use of increased concentrations of ciclopirox. CONCLUSIONS: The study supports the use of 1% ciclopirox shampoo in the treatment of seborrheic dermatitis of the scalp. Furthermore, ciclopirox shampoo at each concentration was found to be safe and well tolerated.

Rationale of frequency of use of ciclopirox 1% shampoo in the treatment of seborrheic dermatitis: results of a double-blind, placebo-controlled study comparing the efficacy of once, twice, and three times weekly usage.

BACKGROUND: Seborrheic dermatitis is a common inflammatory skin disorder. Although the precise etiology of seborrheic dermatitis is uncertain, yeasts of the genus Malassezia have been implicated. Ciclopirox is a broad-spectrum, hydroxypyridone-derived, synthetic antifungal agent with anti-inflammatory properties. METHODS: A total of 183 patients were enrolled in this randomized, parallel-group, double-blind, vehicle-controlled trial designed to compare three different application frequencies of ciclopirox 1% shampoo: once, twice, and three times weekly. The main efficacy parameters were based on 6-point ordinal scales describing the disease's signs and symptoms (scaling, inflammation and itching), global status of seborrheic dermatitis, and global change of seborrheic dermatitis. RESULTS: Each application frequency of ciclopirox 1% shampoo was found to significantly improve the signs and symptoms of seborrheic dermatitis of the scalp after 4 weeks of treatment. Furthermore, the therapeutic index calculated from the global change in seborrheic dermatitis score increased with increasing application frequency; therapeutic index scores increased from vehicle (1.25) to ciclopirox 1% once (3.30), twice (3.50), and three times (3.56) weekly. No serious adverse events were recorded during the course of the study. CONCLUSIONS: Ciclopirox 1% shampoo, applied once, twice or three times weekly, is a safe and acceptable preparation that improves seborrheic dermatitis of the scalp, suggesting that this is an alternative treatment for this indication.

Safety and efficacy of ciclopirox 1% shampoo for the treatment of seborrheic dermatitis of the scalp in the US population: results of a double-blind, vehicle-controlled trial.

BACKGROUND: Seborrheic dermatitis is a common inflammatory skin disorder. Yeasts of the genus Malassezia have been implicated in the etiology of seborrheic dermatitis, although this connection remains controversial. Ciclopirox is a synthetic, hydroxypyridone-derived, broad-spectrum antifungal agent with anti-inflammatory properties. METHODS: A total of 499 US patients with seborrheic dermatitis of the scalp were randomized to apply either ciclopirox shampoo 1% or vehicle twice weekly for 4 weeks. The main efficacy parameters were based on 6-point ordinal scales describing the disease's signs and symptoms (scaling, erythema and itching) and a 6-point scale providing a global evaluation of the status of seborrheic dermatitis. RESULTS: Ciclopirox was significantly better than vehicle in effectively treating seborrheic dermatitis. 'Effective treatment' (score of 0 or 1 for disease status, scaling and erythema) was achieved in 26.0% of ciclopirox-treated patients compared with 12.9% of vehicle-treated patients (P = 0.0001; OR: 2.383, 95% CI: 1.494-3.799). The majority of subjects experienced adverse events that were mild in intensity, with skin and appendage reactions the most commonly reported, at similar frequency in both groups. CONCLUSIONS: Ciclopirox shampoo 1% is effective and safe in the treatment of seborrheic dermatitis of the scalp.

Graham Little-Piccardi-Lassueur syndrome associated with androgen insensitivity syndrome (testicular feminization).

Graham Little-Piccardi-Lassueur syndrome is characterized by the presence of cicatricial alopecia on the scalp, keratosis pilaris in the skin of trunk and extremities, and non-cicatricial hair loss in pubis and axillae. A frequent form of male pseudohermaphroditism is complete androgen insensitivity syndrome (CAIS), also known as testicular feminization syndrome. It refers to genetic males with XY karyotype who, owing to a lack of sensitivity in the peripheral androgenic receptors, develop a female phenotype. Axillary and pubic hair is typically scarce or absent. To our knowledge, this is the first case describing the association of the two processes. The presence of both processes in the same patient furthers our understanding of Graham Little-Piccardi-Lassueur syndrome as it rejects the influence of androgens in the alopecias accompanying this syndrome. The coincidence of non-cicatricial alopecia in axillary and pubic hair in both processes is also remarkable.

Cutis verticis gyrata secondary to acne scleroticans capitis.

We report the case of a 35-year-old patient with secondary cutis verticis gyrata (CVG) that histologically presented as acne scleroticans capitis. Clinically, the diagnosis of acne conglobata was made. The CVG developed under systemic corticosteroid treatment of an ulcerative colitis. Corticosteroids were discontinued and a therapeutic attempt was made with isotretinoin. Although under this treatment the conglobate acne healed, the CVG remained unaltered. Dermatosurgical intervention by a scalp reduction plasty finally resulted in a marked improvement of symptoms and acceptable cosmetic outcome.

Perifolliculitis capitis abscedens et suffodiens.

Perifolliculitis capitis abscedens et suffodiens (PCAS) is rare chronic, suppurative and inflammatory scalp disease. Its aetiology and pathogenesis is not completely understood. The treatment is usually difficult and often disappointing. We report a case of 29-year-old male who presented with tender, fluctuant nodules and abscesses, with draining pus and patchy alopecia on his scalp for 3 years. A skin biopsy from scalp lesions revealed features that are characteristic of perifolliculitis. Initially, the patient was treated with periodic incision and drainage of the scalp abscesses. The answer was very poor. When admitted to our department, isotretinoin was started at daily dose of 30 mg, because initially his cholesterol and triglyceride levels were mildly increased. When dose was reduced to 10 mg the levels of cholesterol and triglyceride remained normal. A response to treatment was excellent and rapid. The treatment of PCAS represents usually difficulties and frustration for both the patient and the physician. A long course of isotretinoin can be considered as one of the most effective treatment for PCAS.

Frontal fibrosing alopecia: a survey in 16 patients.

BACKGROUND: Postmenopausal frontal fibrosing alopecia (PFFA) was described by Kossard et al. as a progressive recession of the frontal hairline affecting particularly postmenopausal women. Further cases of PFFA have been reported to date, all of them considering it as a variant of lichen planopilaris on the basis of its clinical, histological and immunohistochemical features. OBJECTIVE: To describe clinical features, and response to treatment of 16 cases of frontal fibrosing alopecia diagnosed at our department in the last 6 years. METHODS: In addition to clinical data, biopsies and laboratory tests (antinuclear antibodies, sex hormones, thyroid hormones) were performed in order to rule out other causes of scarring alopecia. Patients were treated with intralesional corticosteroids, finasteride, and minoxidil, depending on the stage of the disease and association to androgenetic alopecia. RESULTS: All patients presented progressive alopecia localized to the frontal and temporal hairlines. Eight patients (50%) had loss of eyebrows, and six patients (37.5%) had axillar alopecia. Ages ranged from 45 to 79. Three of these women were premenopausal. Androgenetic alopecia was evident in seven patients (43.8%). All patients biopsied showed perifollicular lymphocitic infiltrate with lamelar fibrosis limited to the upper portions of the follicle. The progression of the condition stopped in most patients after a variable period on treatment. When treatment was abandoned the alopecia progressed to 'clown alopecia' appearance. DISCUSSION: Cases of Kossard's type scarring alopecia affecting premenopausal women made us consider that this condition is not exclusive of postmenopausal women. Differential diagnosis should take into account conditions like female androgenetic alopecia, fibrosing alopecia in a pattern distribution, alopecia areata, and chronic lupus erythematosus. Except for the pattern of alopecia, lichen planopilaris and frontal fibrosing alopecia are indistinguishable, thus the latter is included as a variant of lichen planopilaris. Although the disease tends to spontaneous stabilization, intralesional and topical corticosteroids, and anti-androgens may stop the progression of the disease and improve the female androgenetic alopecia that usually is associated to FFA.
