Randomized, placebo-controlled, double-blind study on clinical efficacy of ciclopiroxolamine 1% cream in facial seborrhoeic dermatitis.

BACKGROUND: Antifungal agents are beneficial in the treatment of seborrhoeic dermatitis. OBJECTIVES: To perform a randomized, vehicle-controlled, double-blind clinical study with an antifungal ciclopiroxolamine (CIC) 1% cream in patients with mild-to-moderate seborrhoeic dermatitis of the face. METHODS: One hundred and twenty-nine patients were enrolled, 57 patients in the CIC group and 72 patients in the vehicle group, and comprised the study population for efficacy (intent-to-treat analysis) and safety. Patients were randomly allocated to apply either the CIC cream or the vehicle on their facial lesions, twice daily for a maximum of 28 days (initial phase), followed by a once daily application of the test products for another 28 days (maintenance phase). Test lesions were defined as lesions localized in the nasolabial folds and/or the eyebrow. The main efficacy parameter (end-point) was the proportion of patients who achieved complete disappearance of erythema and scaling (treatment responders) at the end of the initial phase (28 days or less) and of the maintenance phase (28 days). RESULTS: At baseline, both treatment groups were comparable in terms of demographic data and lesional status. At the end of the initial phase, responders to treatment were higher with CIC (25 patients, 44%) than with the vehicle (11 patients, 15%) (P < 0.001, Fisher exact test). At the end of the maintenance phase, responders in both groups were even higher, comprising 27 patients (63%, n = 43) in the CIC group and 15 patients (34%, n = 44) in the vehicle group (P < 0.007, intergroup analysis). The local tolerance was good in the two groups, except for a higher rate of lesional exacerbation in the vehicle group. No drug-related systemic adverse event was observed during the study. CONCLUSIONS: CIC administered in a cream demonstrated a good therapeutic value in mild-to-moderate seborrhoeic dermatitis of the face.

Hereditary complement (C9) deficiency associated with dermatomyositis.

A 28-year-old Japanese woman with hereditary complement (C9) deficiency and dermatomyositis is reported. She had a 3-year history of facial erythema and a 1-month history of progressive muscle weakness. Clinical and laboratory findings were suggestive of dermatomyositis; muscle biopsy confirmed an inflammatory myopathy. An unexpected finding, however, was the low titre of serum haemolytic complement (CH50). Treatment with prednisolone resulted in marked clinical improvement but did not affect the CH50 titre. Further investigation revealed a selective and total absence of the ninth complement component (C9), with direct DNA sequence analysis revealing a non-sense mutation at Arg95 of the C9 gene. This case demonstrates that the muscle lesions of dermatomyositis can occur in the presence of a complement defect that would prevent the formation of the C5b-9 membrane attack complex.

Necrotizing infundibular crystalline folliculitis.

We describe a 22-year-old woman with a background of acne who developed multiple folliculocentric facial papules associated with sharply demarcated waxy, keratotic plugs. Multiple skin biopsies showed umbilicated craters that were filled with dispersed bundles of eosinophilic filaments embedded in a pale amorphous matrix forming a plug. The plugs bulged into the upper dermis. Serial sections showed vacuolar and filamentous destruction of the infundibular and adjacent perifollicular epithelium and a close relationship of the crystalline necrosis to follicles. Electron microscopy revealed that the filamentous bundles were tonofilaments. No fresh material was available for polarization and the paraffin sections failed to polarize. The clinical and pathological findings of the lesions in our patient were identical to those reported as a new perforating disorder with urate-like crystals. Our case indicates that the process may represent crystalline folliculocentric necrosis rather than a primary perforating disorder. The nature and basis of the crystals that have a urate-like appearance remain to be determined.

Sensitive skin: an epidemiological study.

BACKGROUND: There is a growing awareness that some individuals exhibit heightened skin sensitivity, particularly on the face, and have a high incidence of adverse reactions to cosmetics and toiletries. OBJECTIVES: To carry out an epidemiological study to assess the prevalence of sensitive skin and cosmetic-related adverse events in a U.K. population, and to examine possible factors that may be associated with sensitive skin. METHODS: Self-assessment questionnaires were sent out to 3300 women and 500 men, randomly selected, who were over the age of 18 years and lived within a 10-mile radius of High Wycombe (Bucks.). Fifty non-responder women were also questioned by telephone to ensure that the postal responders were representative of the population as a whole. RESULTS: The response rates were 62% for women and 52% for men, with the incidence of self-reported skin sensitivity being 51.4% and 38.2%, respectively. Ten per cent of women and 5.8% of men described themselves as having very sensitive skin. Fifty-seven per cent of women and 31.4% of men had experienced an adverse reaction to a personal product at some stage in their lives, with 23% of women and 13.8% of men having had a problem in the last 12 months. Among the women, symptoms of cosmetic-induced subjective sensory skin discomfort (burning, stinging, itching etc.) occurred more commonly in the sensitive skin cohort (53%) than in those who regarded themselves as non-sensitive (17%). An atopic diathesis in women did not appear to be a predictive factor for sensitive skin, the incidence of self-perceived sensitive skin being equivalent for atopics (49%) and non-atopics (51%). Furthermore, some 34% of atopic women described themselves as being non-sensitive. Nevertheless, the incidence of atopy was higher among the women in the sensitive skin group (49%) than among those in the non-sensitive group (27%). Dry skin and a predilection for blushing/flushing were associated factors for sensitive skin. CONCLUSIONS: Our survey indicates that sensitive facial skin is a common problem for women and men in the U.K. and points to the need for the development of personal products designed for this skin phenotype.

An open study of a lotion formulation to improve tolerance of tacrolimus in facial atopic dermatitis.

BACKGROUND: We identified 19 patients with facial atopic eczema who failed to respond to tacrolimus (FK506) ointment, although tacrolimus ointment has shown excellent benefit for the treatment of recalcitrant facial erythema in most patients with atopic dermatitis. OBJECTIVES: We attempted to determine the efficacy of an original lotion formulation of tacrolimus for facial atopic dermatitis resistant to tacrolimus ointment. PATIENTS/METHODS: Recalcitrant facial erythema of these 19 patients was treated with an original tacrolimus lotion preparation for 6 months. Patch testing with white petrolatum was performed in both the 19 patients and in 30 other atopic dermatitis patients who had experienced excellent results with tacrolimus ointment. RESULTS: Of the 19 resistant patients, those whose symptoms were greatly or moderately improved by the lotion were 95%, 89% and 89% after 2 weeks, 3 months and 6 months of treatment, respectively. Further, patch testing to petrolatum showed positive reactions in several (six of 19) patients, compared with none of 30 controls with atopic eczema that had responded to topical tacrolimus ointment. CONCLUSIONS: The tacrolimus lotion had a significant effect on the recalcitrant facial erythema in adult patients with atopic dermatitis who were resistant to tacrolimus ointment. We suggest that one reason for the unresponsiveness to tacrolimus ointment may be because of contact sensitivity to white petrolatum.

Cutaneous sarcoidosis successfully treated with topical tacrolimus.

Sarcoidosis is a disorder characterized by macrophage- and T-cell-mediated responses to as yet unidentified infectious antigens or autoantigens. We describe a 62-year-old woman with a 10-year history of orange-yellow plaques of sarcoidosis on her face. Her cutaneous lesions responded to topical tacrolimus ointment after unsuccessful treatment with topical and systemic corticosteroids. No adverse effects were noted with topical tacrolimus in this patient. We discuss the mode of action by which this immunosuppressive agent may act against sarcoidosis.

Cutaneous Mycobacterium fortuitum infection mimicking lupus vulgaris.

We report a woman with a lupus vulgaris-like skin eruption caused by Mycobacterium fortuitum. The presence of mycobacteria was confirmed with tissue culture and also the detection of mycobacterial heat shock protein 65 (hsp65) DNA in the biopsy specimen. The eruption resolved after treatment with amikacin and clarithromycin. Lupus vulgaris-like lesions might be included in the clinical spectrum of infections caused by rapidly growing mycobacteria.

The effect of niacinamide on reducing cutaneous pigmentation and suppression of melanosome transfer.

BACKGROUND: Cutaneous hyperpigmentation occurs in multiple conditions. In addition, many Asian women desire a lighter skin colour. Thus, there is a need for the development of skin lightening agents. Niacinamide is a possible candidate. OBJECTIVES: To investigate the effects of niacinamide on melanogenesis in vitro and on facial hyperpigmentation and skin colour in vivo in Japanese women. METHODS: Melanin production was measured in a purified mushroom tyrosinase assay, cultured melanocytes, a keratinocyte/melanocyte coculture model, and a pigmented reconstructed epidermis (PREP) model. The clinical trials included 18 subjects with hyperpigmentation who used 5% niacinamide moisturizer and vehicle moisturizer in a paired design, and 120 subjects with facial tanning who were assigned to two of three treatments: vehicle, sunscreen and 2% niacinamide + sunscreen. Changes in facial hyperpigmentation and skin colour were objectively quantified by computer analysis and visual grading of high-resolution digital images of the face. RESULTS: Niacinamide had no effect on the catalytic activity of mushroom tyrosinase or on melanogenesis in cultured melanocytes. However, niacinamide gave 35-68% inhibition of melanosome transfer in the coculture model and reduced cutaneous pigmentation in the PREP model. In the clinical studies, niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use. CONCLUSIONS: The data suggest niacinamide is an effective skin lightening compound that works by inhibiting melanosome transfer from melanocytes to keratinocytes.

Hydroa vacciniforme-like primary cutaneous CD8-positive T-cell lymphoma.

An 8-year-old Taiwanese girl had a 6-month history of a relapsing papulovesicular eruption on her face that resembled hydroa vacciniforme (HV). Histologically, there was a dense infiltration of large atypical lymphocytic cells expressing CD8. TCR-gamma gene rearrangement study revealed a monoclonal band present in the DNA extracted from the specimen. A diagnosis of CD8+ cutaneous T-cell lymphoma (CTCL) was made. The patient was treated with Chinese herbal drugs and her skin lesions waxed and waned. At this writing, 11 months after establishment of the diagnosis, the skin lesions have been limited to the facial area and no definite evidence of systemic involvement is noted. To our knowledge, this is the first case of CD8+ primary CTCL with clinical features resembling HV.
