Occupational hand dermatoses in hospital cleaning personnel.

Hospital cleaning personnel were examined for occupational dermatoses. 356 persons were included in the study. The age ranged from 20 to 63 years with a mean of 40.1 years. The period prevalence rate of moderate and severe eczema was 12% (10% in men and 19% in women). In 88%, the eczema was of a duration longer than 2 years. Positive patch tests were found in 10% of men and 53% of women with eczema. The main allergens were nickel, cobalt, chromate and rubber chemicals. Positive tests to cleaning agents were rare. One case of contact allergy to sodium dichloro-iso-cyanurate and one to lysol were diagnosed. Irritant factors played a major rôle in most cases (92%). Fungus infection as a cause or complication in hand eczema should not be left out of consideration: in 2 persons, a mycosis of hands and/or fingernails was diagnosed.

Occupational dermatoses and allergy to metals in Polish construction workers manufacturing prefabricated building units.

The incidence of dermatoses and allergy to metals (Cr, Co, Ni) was determined in 1782 workers exposed to cement, waste fly ash and asbestos cement. They were also exposed to reclaimed (used), mineral oils. Dermatitis was found in 23.6% of the subjects, and oil acne in 11.2%. Allergy to chromium was found in 23% of the subjects; the % of definitely positive patch test results (the total of positive +(+) and strongly positive +(+)+ was, however, 8.6%. Allergy to cobalt was found in 13.4% of the subjects examined (definite in 3.1%). Allergy to nickel was found in 2.7% of the subjects (definite in 1.1%). The risks of occurrence of occupational skin disease and allergy to metals in subjects exposed to ash were found to be lower than in subjects exposed to cement, and were similar to those in subjects exposed to asbestos cement. Overall chromium, cobalt and nickel contents in ash and asbestos were higher than in cement. Soluble chromium compound content in ash was lower than in cement from European countries and similar to that in American cement.

Occupational dermatoses in a Swedish aircraft plant.

A survey of occupational dermatoses, based on a questionnaire, clinical examination and patch testing, was carried out among 341 workers in an aircraft plant. The questionnaire was answered by 330 workers (96.8%). Present or previous skin disease was reported by 92 employees, who were all subjected to physical examination and patch testing. Patch testing was conducted with a standard series, as well as with a series of substances and products representing the work environment. Occupational contact allergies were established in 12 employees. In total, the figure for occupational skin diseases was 16.1% (55 workers), when calculated for all employees.

[Anogenital dermatoses--allergic and irritative causative factors. Analysis of IVDK data and review of the literature].

BACKGROUND: Anogenital dermatoses (AGD) are common and often very distressing. Clinically it is often unclear if allergic contact dermatitis or irritant dermatitis is involved. In order to optimize therapy and prophylaxis, it is essential to identify relevant allergens or irritants. PATIENTS AND METHODS: Data of the Information Network of Departments of Dermatology (IVDK, data center in Göttingen) collected between 1999 and 2003 were analyzed. The anogenital area was involved in 1 168 patients with suspected allergic contact dermatitis. Clinical variables and patch test results were statistically compared with the remaining IVDK patch test population, the latter standardized for age and sex. RESULTS: Allergic contact dermatitis had been suspected prior to patch testing in 39.5 %, while in 24.6 % this diagnosis was eventually confirmed. Irritant contact dermatitis was diagnosed in 11.8 %. Other diagnoses, included balanitis, lichen sclerosus et atrophicus and herpes genitalis. Positive reactions to cinchocaine (6.6 %), bufexamac (3.5 %) and benzocaine (2.4 %) were observed significantly more often among patients with anogenital dermatitis. Among those in whom co-factors were considered important (n = 422), wetness (38.4 %), occlusion (30.3 %), mechanical strain (4.7 %) and heat (3.6 %) were mentioned as irritation factors. CONCLUSION: Because of the significantly higher frequency of sensitization to cinchocaine, benzocaine and bufexamac in patients with anogenital dermatitis, these ingredients should be used only with caution. According to the literature, ingredients of toiletries, cosmetics and contraceptives of any kind seem to cause allergic contact dermatitis rarely although there are several case reports. Comprehensive patch test including the standard series plus major sensitizers such as cinchocaine, benzocaine and bufexamac, and in particular patients' own skin care products, is recommended.

Association between milk production, somatic cell count and bacterial dermatoses in three dairy cattle herds.

OBJECTIVE: To determine the correlations between three bacterial dermatoses in cattle, milk production and bulk-milk somatic cell count (BMSCC). DESIGN: Field observations in three dairy cattle herds. METHODS: Milk production, BMSCC, fertility and all herd diseases were recorded by computerised dairy management systems. Each herd was visited twice weekly and the clinical signs, course of diseases and morbidity and culling rates were noted. Bulk-tank milk was sampled twice monthly and analysed for somatic cell count. Bacteriological and histological examinations were carried out from samples collected from affected animals in the respective herds. RESULTS: The acute exudative form of dermatophilosis was diagnosed only in first-calving cows. The morbidity rate was 53% and the culling rate was 16% of the affected animals. The BMSCC increased by a factor of 2.4 times, and there was an average loss of milk production of 30%/cow/day in affected animals. Ulcerative lymphangitis was diagnosed in first-calving cows (22%) and older cows (15%). The culling rate was 28%. The BMSCC increased by a factor of 17.3 times, and the average loss of milk production was 5.5%/affected animal/day. Papillomatous digital dermatitis (PDD) was diagnosed in first-calving cows (25%) and in older cows (18%). The culling rate was 8%. The BMSCC increased by a factor of two times, and the average loss of milk production was 1.7%/affected animal/day. CONCLUSIONS: The correlations between three skin diseases (ulcerative lymphangitis, dermatophilosis, papillomatous digital dermatitis), milk production and BMSCC have been found to be unfavourable.

PUVA therapy is preferable to UVB phototherapy in the management of HIV-associated dermatoses.

Both methoxsalen plus UVA (PUVA) therapy and UVB phototherapy are commonly used in the management of human immunodeficiency virus-associated dermatoses but UVB phototherapy appears to be the preferred treatment. There are several considerations, in particular therapeutic efficacy and therapeutic profile, which suggest that PUVA therapy might be more effective. This needs to be established in clinical trials.

A clinico-pathological study of vulval dermatoses.

A long-term review of 108 women suffering from various forms of vulval dermatosis is described and a detailed analysis of those with chronic hypertrophic vulvitis, lichen sclerosus et atrophicus, and neurodermatitis is made. One case of neurodermatitis and two cases of lichen sclerosus progressed to carcinoma but no case of chronic hypertrophic vulvitis became malignant. It is possible that vulval dermatoses occur more commonly in the nulliparous than in the parous women and there is a slight preponderance of women who are blood group A. It is suggested that the term "leukoplakia" should be abandoned and that vulval lesions should be described in precise and meaningful histological terms.

Neutrophilic dermatoses: pyoderma gangrenosum and Sweet's syndrome.

Pyoderma gangrenosum and Sweet's syndrome are classified as neutrophilic dermatoses as they exhibit intense dermal inflammatory infiltrates composed of neutrophils with little evidence of a primary vasculitis. They share several characteristics and respond to immunosuppressives. Aetiology is felt to represent a manifestation of altered immunologic reactivity. Patients with both conditions concurrently have been described. Diagnosis is based on clinical and histopathological findings. However, clinically the typical forms of the two conditions are quite distinct: pyoderma showing cutaneous ulceration with a purple undermined border and Sweet's syndrome having tender, erythematous, nonulcerated plaques and nodules. Approximately 50% of cases of pyoderma are associated with a specific systemic disorder. These include inflammatory bowel disease, rheumatoid arthritis, non-Hodgkin's lymphoma and myeloproliferative disorders. Many associations with Sweet's syndrome have been described, including acute myeloid leukaemia, myeloma and adenocarcinomas, and haematological malignancy. There is overlap between the two conditions with lesions categorised as Sweet's syndrome being clinically more characteristic of atypical pyoderma and vice versa. We believe that pyoderma and Sweet's syndrome represent a continuum of spectrum of disease. The reason for the clinical differences between the conditions is unclear and merits further investigation but may be explained by varying levels of intensity and extent of the inflammatory process. This review will describe the pathogenesis, clinical features, diagnosis, associations and treatment of the two conditions.

Acneiform dermatoses.

Acneiform dermatoses are follicular eruptions. The initial lesion is inflammatory, usually a papule or pustule. Comedones are later secondary lesions, a sequel to encapsulation and healing of the primary abscess. The earliest histological event is spongiosis, followed by a break in the follicular epithelium. The spilled follicular contents provokes a nonspecific lymphocytic and neutrophilic infiltrate. Acneiform eruptions are almost always drug induced. Important clues are sudden onset within days, widespread involvement, unusual locations (forearm, buttocks), occurrence beyond acne age, monomorphous lesions, sometimes signs of systemic drug toxicity with fever and malaise, clearing of inflammatory lesions after the drug is stopped, sometimes leaving secondary comedones. Other cutaneous eruptions that may superficially resemble acne vulgaris but that are not thought to be related to it etiologically are due to infection (e.g. gram-negative folliculitis) or unknown causes (e.g. acne necrotica or acne aestivalis).

Optimal conditions of 1 M NaCl splitting technique to demonstrate basement membrane zone antigens in bullous pemphigoid, epidermolysis bullosa acquisita and linear IgA bullous dermatoses.

We compare a series of conditions for inducing lamina lucida separation through normal skin specimens using 1 M NaCl for the detection of basement membrane zone auto-antibodies using indirect immunofluorescence. Skin was split at room temperature and at 4 degrees C with and without phenylmethylsulphonyl fluoride. Our results demonstrate that for the detection of bullous pemphigoid and epidermal-binding linear IgA bullous dermatoses antibodies skin should be split at 4 degrees C with enzyme inhibitors. For epidermolysis bullosa acquisita and dermal-binding antibodies skin can be split at room temperature.

Sweat-related dermatoses: old concept and new scenario.

This review focuses on dermatoses that are caused by the presence of sweat--a previously underemphasized subject. A working classification based on 'internal sweating' (extravasated sweat in the dermis and epidermis) and 'external sweating' (sweat on skin surface) is proposed. Clinical observations suggest that transient acantholytic dermatosis is the consequence of extravasated sweat; we speculate that it is an example of sweat-related, protease-induced epidermal acantholysis. Neutrophilic eccrine hidradenitis may represent a sweat-related drug reaction. We emphasize the well-recognized phenomenon of 'sweat retention syndrome' in a new scenario: hospitalized febrile patients, increasing use of chemotherapy, new life style. The concept of 'sweat-gland-mediated cutaneous inflammation' is proposed.

Skin cellular retinoid-binding proteins and retinoid-responsive dermatoses.

We have previously found an important increase of cellular retinoic acid-binding protein (CRABP) in psoriatic plaques whereas the cellular retinol-binding protein (CRBP) was not elevated compared to normal human skin and nonlesional psoriatic skin. In the present study we analyzed CRABP and CRBP levels in a panel of dermatoses in order to address several questions raised by the above findings. Three observations were made: CRBP showed little or no variations whereas CRABP was either normal (seborrheic keratosis, lichenification, nonlesional psoriatic and nonlesional Darier disease skin) or elevated (psoriatic plaques, lamellar ichthyosis, lesional Darier disease, pityriasis rubra pilaris, keratosis pilaris); high levels of CRABP might indicate a greater sensitivity of the lesions to systemic synthetic retinoids with a carboxyl group in the C15 position, and systemic administration of etretin increased the levels of CRABP but not CRBP. These observations suggest that CRABP might be the receptor for synthetic retinoids in the skin and that its analysis might be useful in monitoring retinoid therapy.

Interleukin-1-like activity in horny layer extracts: decreased activity in scale extracts of psoriasis and sterile pustular dermatoses.

Interleukin-1 (IL-1)-like activity was assessed in scale extracts prepared from skin specimens from 36 cases of psoriasis and other dermatoses characterized by the formation of sterile subcorneal pustules. IL-1 activity was detected in only 2 samples. In contrast, much higher IL-1 activity was demonstrated in horny tissue extracts prepared either from normal skin or from noninflammatory skin such as plantar callus, scar or ichthyosis. No correlation was found between neutrophil chemotactic activity and IL-1 activity demonstrable in horny tissue extracts.

A randomized trial on the D-homosteroid domoprednate (Ro 12-7024) in the treatment of dermatoses.

39 patients with bilateral dermatoses, mainly psoriasis vulgaris and atopic dermatitis, were treated with 0.1% Ro 12-7024 ointment and 0.1% betamethasone valerate ointment according to a double-blind, right-left, randomized design. Treatment lasted up to 4 weeks. 5 patients did not complete the trial. Assessment of efficacy, expressed as degree of healing in percent of treated skin area and according to an overall assessment of efficacy made by both physician and patient only revealed marginal, mostly statistically insignificant differences, with a trend in favor of betamethasone. Patients' preferences for one of the two treatments favored betamethasone valerate in 17 cases and Ro 12-7024 in 5 cases; 13 cases were ties (p less than 0.001). With the exception of one case of bilateral erythema and itching no side effects were reported. The efficacy of the D-homosteroid Ro 12-7024 is evidently of the same order as that of the group III steroid betamethasone valerate, and the tolerance of the two ointments is good and equal.

Temetex in the treatment of steroid-responsive dermatoses.

Five hundred and seventy-five patients with various steroid-responsive dermatoses were studied for up to six weeks in eighty-eight separate general practices using a new topical corticosteroid. Temetex (diflucortolone valerate 0-1%). It was concluded that Temetex is both effective and well tolerated in a wide variety of conditions, especially eczema and psoriasis. It was also shown that a large-scale general practice trial can be carried out efficiently with a very high compliance rate.

An evaluation of once-daily applications of diflorasone diacetate in eczematous dermatoses.

The efficacy of once-daily applications of 0.05% diflorasone diacetate in a cream or ointment formulation was evaluated in a 3-week study of 301 patients with eczematous dermatoses. The lesions were classified by severity and included those of an acute, sub-acute or chronic nature. Clinical evaluations were based on overall lesion improvement and improvement in specific signs and symptoms. Over 80% of patients reported the therapy to be good or excellent. Sixteen patients reported side-effects consisting largely of transient burning and stinging.
