AIMS: To determine the diagnostic accordance between histopathological and direct immunofl uorescence diagnosis of patients with autoimmune vesiculobullous skin diseases. BACKGROUND: The term pemphigus refers to a group of autoimmune blistering diseases mediated by autoantibodies directed against desmoglein proteins. The differentiation between the various bullous diseases is important for treatment and prognosis. Direct immunofl uorescence microscopy is still the gold standard in differentiating these diseases. METHODS: Patients with clinical diagnosis of vesiculobullous dermatitis from pemphigus group were included in the study. We retrospectively analyzed histopathologic and direct immunofl uorescence results from skin or mucosal samples over 15-year period. RESULTS: 81 patients were included. The accordance was good in pemphigus vulgaris and pemphigus herpetiformis, but low in pemphigus vegetans, pemphigus foliaceus and pemphigus erythematosus. No accordance was in Hailey-Hailey disease and Grover´s disease. Uncommon result in our analysis included: intraepidermal IgG and IgM depositions at DIF in one Grover´s disease patient. CONCLUSION: Our results confi rmed the relevance of direct immunofl uorescence assays as a necessary diagnostic method for the defi nitive diagnosis of autoimmune blistering disease in the case, where the clinical feature and the results of histopathology are not clear (Tab. 4, Fig. 5, Ref. 26).

We report a 38-year-old woman with relapsing-remitting multiple sclerosis, treated with subcutaneous injections of interferon beta (IFN-beta)-1b every other day. Disseminated cutaneous lesions were observed after 3 injections. These symptoms reappeared after drug readministration. The histopathological examination of the skin specimens confirmed nonspecific cutaneous lymphocytic vasculitis. The patient's outcome was favorable after corticosteroid placement and discontinuing IFN-beta therapy. Isolated lymphocytic cutaneous vasculitis linked to IFN-beta-1b therapy is suspected as a new association.

Summary A lip cream with special propolis extract GH 2002 at a concentration of 0.5% (199 patients) was tested against aciclovir 5% (198 patients) in the treatment of episodes of herpes labialis under double-blind conditions. Upon inclusion, all patients were in the vesicular phase. Application was five times daily of approximately 0.2 g of cream to the entire upper and lower lip. The primary parameter was the difference in time between groups to complete encrustation or epithelization of the lesions. Secondary endpoints were the course of typical herpes symptoms (pain, burning and itching, tension and swelling), the global assessment of efficacy and the safety of application. The predefined clinical situation was reached after a (median) 3 days with propolis and 4 days with aciclovir ( p < 0.0001). Significant differences in favor of propolis were also found for all secondary parameters. No allergic reactions, local irritations or other adverse events occurred.

Distribution of Candida species was investigated by examining 245 samples from skin lesions and nails. The isolates were identified using standard laboratory methods including germ tube test, micromorphology of colonies on rice agar, the commercial kit, saccharide assimilation and fermentation tests. Eight species of Candida were identified: C. albicans accounted for 56.4% of the isolates, C. parapsilosis 29.1, C. tropicalis 7.8, C. pulcherrima 2.9, C. guilliermondii 1.5, C. krusei and C. zeylanoides for 0.9% each, and C. robusta for 0.5%. The factors significantly associated with colonization were prolonged antibiotic therapy, parenteral nutrition, low birth body mass of infants, intubation, duration of stay in hospital, indwelling intravenous catheter, malignancies, diabetes, surgery, and obesity.

Mycological investigation of 108 nail specimens taken from a total of 41 patients examined over three years included direct microscopy and repeated cultures. A higher incidence of onychomycosis of the fingernails (75%) was observed in women while afflictions of the toenails (71%) prevailed in men. The highest prevalence of onychomycosis was found in patients between 50 and 70 years of age. Candida albicans was the dominant organism causing onychomycosis (prevalence rate 60.9%), followed by C. parapsilosis (19.6%), C. tropicalis (9.8), C. krusei (4.9), C. guilliermondii and C. zeylanoides (2.4% each).

A total of 43 patients, 11 males and 32 females, with paronychia of the fingernails were examined for the presence of Candida spp. The yeast species isolated were identified using standard laboratory methods, including germ-tube production, morphology on rice agar with Tween 80, and mainly fermentation and assimilation of saccharides. In the male group, two Candida species were detected: C. albicans as the dominant species in 9 patients and C. parapsilosis in 2 cases. Similarly, C. albicans was the prevalent species also in females (n = 17); other Candida species detected were C. parapsilosis (n = 7), C. tropicalis (5) and C. krusei (3). In addition to the genus Candida, the following anaerobic and aerobic microorganisms were isolated from patients of both groups: Fusobacterium spp., Bacteroides spp., Staphylococcus aureus, alpha-hemolytic streptococci, group A beta-hemolytic streptococci, Klebsiella pneumoniae, Neisseria spp. and Pseudomonas aeruginosa.

One-hundred patients with candidosis of the skin, mucous membranes and nail plates (confirmed by cultivation) were examined. Topical or systemic antimycotic treatment was successful in 58 patients. After a complete evaluation, 42 patients were found to suffer from factors supporting candidosis--diabetes mellitus (12), anemia (3) and various local factors (10 patients); 27 patients showed a deficiency in cell-mediated immunity. In addition to intensive antimycotic therapy, successful treatment is affected by the actual immunity level and can be ensured by efficient immunomodulation treatment of immunodeficiency.
