Occupational skin diseases: actual state analysis of patient management pathways in 28 European countries.

BACKGROUND: Work-related skin diseases (WSD) are caused or worsened by a professional activity. Occupational skin diseases (OSD) need to fulfil additional legal criteria which differ from country to country. OSD range amongst the five most frequently notified occupational diseases (musculoskeletal diseases, neurologic diseases, lung diseases, diseases of the sensory organs, skin diseases) in Europe. OBJECTIVE: To retrieve information and compare the current state of national frameworks and pathways to manage patients with occupational skin disease with regard to prevention, diagnosis, treatment and rehabilitation in different European countries. METHODS: A questionnaire-based survey of the current situation regarding OSD patient management pathways was carried out with experts on occupational dermatology and/or occupational medicine from 28 European countries contributing to the European Cooperation in Science and Technology (COST) Action TD 1206 (StanDerm) (www.standerm.eu). RESULTS: Besides a national health service or a statutory health insurance, most European member states implemented a second insurance scheme specifically geared at occupational diseases [insurance against occupational risks (synonyms: insurance against work accidents and occupational injuries; statutory social accident insurance)]. Legal standards for the assessment of occupationally triggered diseases with a genetic background differ between different countries, however, in most European member states recognition as OSD is possible. In one-third of the countries UV light-induced tumours can be recognized as OSD under specific conditions. CONCLUSION: OSD definitions vary between European countries and are not directly comparable, which hampers comparisons between statistics collected in different countries. Awareness of this fact and further efforts for standardization are necessary.

Contact allergy to corticosteroids and Malassezia furfur in seborrhoeic dermatitis patients.

BACKGROUND: Seborrhoeic dermatitis (SD) is a chronic skin disease, requiring long-term treatment, which might promote sensitization. Malassezia furfur (Mf) plays an important role in seborrhoeic dermatitis. Objectives The aim of this study was to determine the frequency of contact sensitivity in SD patients. PATIENTS AND METHODS: A total of 100 patients and 20 healthy controls (HC) were investigated: 50 suffering from SD with no previous local corticosteroid treatment (SDN), 50 SD patients treated with local corticosteroids (SDC). Mycological examination for Mf was performed. All patients were patch tested with the baseline standard, corticosteroid series, with 12 commercial corticosteroid preparations frequently used in Croatia; and also with Mf. RESULTS: Malassezia furfur was found in 44 (88%) SDN, 37 (74%) SDC, and in 4 (20%) HC; patch test reaction to Mf was positive in one SDN and in three SDC. Positive patch tests to standard allergens were observed in 17 (34%) SDN, 33 (66%) SDC and 2 (10%) HC. Patch tests to the corticosteroid series revealed positive reactions in 4 SDC and to commercial corticosteroids in seven patients, i.e. 2 SD and 5 SDC. CONCLUSIONS: Patch tests to the baseline series and to both individual corticosteroid and commercial corticosteroid preparations should be performed in SD patients with persistent dermatitis, as contact-allergic reactions may complicate their dermatitis. Sensitization to Mf was found to be infrequent.

Loop excision of the transformation zone (LETZ) as an outpatient method of management for women with cervical intraepithelial neoplasia: our experience.

Between March 1996 and July 1998, 90 patients were treated with diathermy loop excision (LETZ) for cytologically, colposcopically and histologically verified cervical intraepithelial neoplasias (CIN), at the outpatient clinic. In average, the patients were 30.22 years of age, and 61.1% of them were nulliparas. In 80 surgical samples (88.9%), the exocervical and endocervical margins were histologically free of disease. From the total of 65 patients with CIN III diagnosis, 58 (89.2%) had free margins samples. In the post-operative period the patients had a changed vaginal discharge for 16 days. A slight feeling of pain in the abdomen lasted for 2.5 days on the average, and most patients did not take analgetics. Moderate postoperative hemorrhage from the excision site occurred in 5 (5.5%) patients, and was outpatiently treated with electrocoagulation, with no need for blood replacement. In 65 patients (90.3%), the cytological control results were normal. During the follow-up period, 9 patients became pregnant, which resulted in 6 terminal deliveries so far; 2 pregnant women are about to deliver, and one is in the first trimester of pregnancy. Cerclage cervicis has not been performed on any of the patients. LETZ is a safe and simple procedure which can be done at outpatient clinics, it is relatively easily mastered, it is short, quite bearable for patients if done only under local analgesia, the equipment costs are acceptable, and the treatment can be used both diagnostically and therapeutically, since an adequate surgical sample is obtained for histological assessment. Cytological and colposcopical check ups are imperative in the postoperative period.

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.

Pemphigus vulgaris: a review of treatment over a 19-year period.

BACKGROUND: Pemphigus vulgaris is an autoimmune blistering disease of the skin and mucous membranes with a high mortality if left untreated. OBJECTIVE: We present a retrospective analysis of 159 patients with pemphigus vulgaris and pemphigus vegetans who were admitted to the Department of Dermatology and Venereology, Zagreb University Hospital Center (Zagreb, Croatia) from 1980 to 1998. RESULTS: Female to male ratio was approximately 2:1. The mean age was 53 years. During the war years in Croatia (1991-95) we noticed a low incidence of pemphigus vulgaris, and from 1996 to 1998 the incidence almost doubled. Diagnosis was based on histopathology [showing typical pemphigus vulgaris changes in 156 (98%) patients], indirect immunofluorescence [positive in 122 (77%) patients], direct immunofluorescence [positive in 141 (89%) patients], and blister smear cytology (Tzanck test) [positive in 115 (72%) patients]. High dosages of prednisone (100-150 mg) were given to 129 patients, which was combined with azathioprine. Patients with refractory pemphigus vulgaris were treated with intramuscular gold (14 patients) and plasmapheresis (five patients). All patients were treated with local ointments. The prolonged use of high doses of corticosteroids and immunosuppressants caused several complications, in particular, steroid diabetes (37 patients), skin infections (26 patients), arterial hypertension (23 patients), cardiorespiratory diseases (22 patients), sepsis (nine patients), etc. During the hospital treatment, 14 patients died, 10 during 1980-89 and only four during the 1990-98 period. The main causes of death were cardiorespiratory failure (six patients) and sepsis (five patients). CONCLUSIONS: Although pemphigus vulgaris is still a life-threatening disease, today it can be successfully treated with a combination of immunosuppressive agents. Early diagnosis and treatment of pemphigus vulgaris allow a better prognosis with lower mortality rates.

The radiation-attenuated schistosome vaccine induces high levels of protective immunity in the absence of B cells.

Radiation-attenuated cercariae of Schistosoma mansoni elicit consistently high levels of protective immunity in mice. The cell-mediated pulmonary effector mechanisms have been well characterized but the role of B cells and antibodies remains ill defined. We have compared the immune responses of B-cell-deficient (muMT) mice and their wild-type (WT) counterparts following exposure to the attenuated vaccine. Both groups mounted a T helper type 1 (Th1)-biased response in the skin-draining lymph nodes after vaccination. Interferon-gamma was the dominant cytokine secreted by airway leucocytes after challenge in both muMT and WT mice, but there was a somewhat greater Th2 component in the former animals. The cellular infiltrates observed in the airways, and the pulmonary effector foci, were of similar composition in the two groups although some large foci were present in the muMT mice. There was a marked dichotomy in the protection induced in muMT animals by a single vaccination, with two-thirds showing levels similar to their WT counterparts, demonstrating that cell-mediated mechanisms alone can provide adequate protection. The remaining muMT mice had a mean worm burden identical to that of their challenge controls. A possible explanation is that a proportion of the muMT animals have a genetic defect closely associated with the mu-heavy-chain locus on chromosome 12, which affects their ability to mount a protective cell-mediated response. Three vaccinations enhanced the immunity of WT animals, most likely by augmenting antibody-mediated mechanisms. In contrast, no enhancement was seen in muMT mice, suggesting that the cell-mediated response is not boosted by multiple exposures to attenuated larvae.
