A double-blind evaluation was carried out in 40 patients with moderate to severe psoriasis of the scalp to assess the effectiveness of a 0.05% alcoholic solution of clobetasol propionate as compared with a 0.05% alcoholic solution of betamethasone-17,21-dipropionate. Patients were treated on a non-selective basis with a twice a day application for 2 weeks. When comparing the effects on the parameters scaling, induration, erythema and itching it was concluded that clobetasol propionate was superior to betamethasone-17,21-dipropionate as an antipsoriatic compound. Clobetasol propionate did not cause any side-effects, while 2 of the patients using betamethasone-17,21-dipropionate developed a forehead folliculitis during the second week of treatment.

The papular eruption (PE) associated with human immunodeficiency virus infection, although described as a distinctive clinicopathologic entity, has shown a wide range of histologic findings ranging from eosinophilic folliculitis to granuloma annulare. We examined 48 cases of the PE in order to define the histologic spectrum of these lesions, and to correlate these findings with clinical presentations. The most distinctive clinical features are the frequency of these lesions in this population, the large number of lesions, pruritus, and the chronic nature of the lesions. Histologically, the distinctive features are the prominent perivascular factor XIIIa-positive dermal dendritic cells, atypical vascular proliferation, and dermal fibrosis sometimes associated with diffuse necrobiotic changes.

We report the case of a 20-year old male patient without significant familial or personal history who presented with a disseminated papular eruption on the abdomen, flanks and buttocks. The eruption was continual and proceeded by outbreaks, but it was not influenced by seasons. Physical examination of the skin, mucosae and skin appendages was otherwise normal. Histological examination showed all the criteria of perforating folliculitis as described by Mehregan and Coskey. On the basis of our case we would put perforating folliculitis back among the perforating dermatoses. The concept of this curious phenomenon is briefly reviewed; perforating folliculitis is part of the third group of the so-called primary forms. The clinical features are suggestive of the disease, with its small pigmented papules centred around a keratotic plug, forming a permanent disseminated eruption. Histology shows a granuloma facing a lateral perforation of the hair follicle, a pseudo-epitheliomatous epithelial hyperplasia and the presence of hair and keratin debris in the perforation. Various keratolytic treatments have been applied without success; retinoids have not been tried. The main diagnostic and nosological problem is Kyrle's disease. In view of clinical and histological data, many authors regard Kyrle's disease as a major form of perforating folliculitis. Pruritus, ascribed to an underlying illness in Kyrle's disease, is thought to increase the importance of the lesions. The specificity of perforating folliculitis is discussed, but it seems that side by side with secondary forms occurring in recognized diseases, there may be primary forms of perforating folliculitis. Dyskeratosis might be a cause of the perforation.

Staphylococci and beta-haemolytic streptococci are usually responsible for causing common primary and secondary skin infections. Mupirocin (Bactroban, Eismycin; trademarks of Beecham Group plc), a new antibiotic unrelated to any other antibacterial agent and developed for topical use only, shows a high level of activity against these bacteria. In an open multicentre study the efficacy and safety of mupirocin (2% in a polyethylene glycol vehicle) was evaluated in 1,391 general practice patients with superficial skin infections. The most common skin infections treated were pyoderma (eg, impetigo, folliculitis) and secondarily infected skin lesions. Treatment consisted of application of the ointment three times daily for an average of nine days. A total of 1,304 patients were evaluable for post-treatment clinical assessment. At the end of the treatment 961 (73.7 per cent) patients were cured and in 293 (22.5 per cent) patients the symptoms of the infection had markedly improved. In total, 525 bacterial strains were isolated from the wounds of 445 patients, predominantly staphylococci (n = 344) and streptococci (n = 93). Local side effects such as burning, itching and reddening were observed in 39 (2.9 per cent) of 1,357 patients. No evidence of systemic toxicity or abnormal laboratory data was noted. Mupirocin 2% ointment proved to be effective and safe in the treatment of primary and secondary skin infections.

As llamas become more common in North America, veterinarians will be called on ever more frequently to deal with their dermatologic problems. Adherence to the basic tenets of the thorough dermatologic work up, including history, physical examination, skin scrapings, cytological examinations, fungal culture, skin biopsies, and assessing response to judiciously chosen trial therapies will offer the best opportunity of arriving at proper diagnoses. Special attention must be paid to the fact that llama skin bears some histological differences that may prove confusing to the uninitiated. A mild degree of hyperkeratosis, a prominent vascular plexus in the superficial dermis that is associated with mild perivascular mononuclear cell accumulations, and regional differences in sebaceous gland size and numbers, all are considered normal findings. Ectoparasites, including sarcoptic mange, chorioptic manage, and pediculosis, appear to be the most common causes of pruritus in the llama. Although ivermectin therapy would appear to be very effective for the treatment of scabies and, indeed, may work well against sucking lice, chorioptic mange and biting lice usually do not respond to this medication. Corticosteroids can be used to treat pruritus in the llama nonspecifically, using the anti-inflammatory dosages established in other species. These drugs are used most appropriately for the management of the allergies that we suspect occur in this species, until better alternative therapies can be developed. Variably pruritic focal areas of alopecia, exudation, and crusting suggest differential diagnoses including bacterial folliculitis and furunculosis, dermatophilosis, dermatophytosis, and coccidioimycosis. The diagnosis of bacterial problems often is made by assessing response to antibiotic therapy. Topical disinfectants and/or systemic penicillin or trimethoprim-sulfadiazine are indicated. Dermatophilosis is treated by cleaning and drying the leasions, applying topical antibiotics, and, occasionally, using parenteral penicillin and streptomycin. Dermatophytosis usually is treated with topical antibiotics only. Captan is one of several therapies of choice. There is no therapy presently available for coccidioidomycosis in the llama. Perhaps most perplexing is the fact that one of the most common dermatopathies seen in the llama is an idiopathic keratinizing disorder that, in some cases, is responsive to zinc supplementation. We have no real idea of the pathogenesis of this problem and recognize that some affected animals will not respond to supplementation.(ABSTRACT TRUNCATED AT 400 WORDS)

Folliculitis, both superficial and deep, has increased in frequency, particularly during the warm months of the year. The frictional trauma from tight-fitting jeans, with overhydration and maceration of the skin, has contributed to the increase. Folliculitis is usually accompanied by pruritus, but when pruritus precedes the folliculitis, there may be another cause in addition to the wearing of tight clothes. Such was the case in our patient who had anal pinworms (Enterobius vermicularis).

The evolution of perforating folliculitis in six patients with chronic renal failure was investigated with special attention to clinical and histopathologic changes in early, evolving, and mature lesions. Different and distinct histologic features at each stage were found. The earliest lesions, follicular pustules, evolved into perforating folliculitis that eventuated in prurigo nodularis. A combined treatment consisting of an anti-staphylococcal antibiotic by mouth, phototherapy, and application of a topical corticosteroid lotion proved helpful in controlling the generalized pruritus and the evolution of the lesions in these cases.

In a study of 46 patients with nodular prurigo (NP), potential metabolic causes of pruritus, such as anaemia, hepatic dysfunction, uraemia and myxoedema, were present in 50%. Focal causes of pruritus were important in 37% and included insect bites, venous stasis, folliculitis and nummular eczema. Psycho-social disorders were recorded in over 50% of patients and were considered relevant in 33%. Clinical and histological appearances ranged from classical NP to chronic lichenified eczema. Neural hyperplasia was not a prominent feature.

We report two cases with adverse cutaneous reactions under lithium medication for manic-depressive disease. The first patient developed follicular keratosis, psoriasiform plaques and seborrheic dermatosis, the second only sclerotic plaques. Cutaneous side-effects that have been associated with lithium therapy include: acneiform eruption, pruritus, maculopapular eruptions, folliculitis, pretibial ulcerations, alopecia...and exacerbation of psoriasis. The exact pathophysiologic mechanism by which lithium induced cutaneous pathology is not completely understood. The various physiologic actions seem to be incomplete in substitution for other extracellular and intracellular cations and interference with cyclic adenosine monophosphate mediated processes.

We describe the case of a young man of Calabrian origin, who came to our observation for the appearance of erythematous pustular, intensely itching, lesions on the arms, trunk and, in a less extent, on the face. The blood count revealed a differential cell count of 16.8% eosinophils. Serum IgE levels were elevated (1000 IU/ml), and T cell subsets showed an increase in CD8+ and a decrease in CD4+ with an inversion of CD4+/CD8+ ratio (= 0.78). The result of the following investigations were either normal or negative: anti-(ds)DNA antibody, anti-nuclear antibody, anti-smooth muscle antibody, anti-striated muscle antibody, serological tests for viral, bacterial, fungal and parasitic diseases and cultural examination of the material from lesion. Histopathological examination of a biopsy specimen from the left arm showed the presence of abundant perivascular inflammatory infiltrate in the dermis and inflammatory infiltrate, with numerous eosinophils, around sebaceous glands. Taken together, all these data suggest the diagnosis of eosinophilic pustular folliculitis, a dermatosis of unknown etiology, with a histopathological picture identical to Ofuji's disease. Eosinophilic pustular folliculitis can be associated with HIV infection or haematological diseases (as non-Hodgkin lymphomas, myeloma, etc.); it was also reported in adult immunocompetent healthy individuals and in children. On the basis of our findings, we propose that this case should be classified as an idiopathic form, as we were not able to demonstrate any associated disease.
