We planned to determine the frequency of sensitivity to European standard patch test allergens in 1038 patients with contact dermatitis. From 1992 to 2004, 1038 patients with the diagnosis of contact dermatitis were patch tested with the European standard series. Seven hundred and five patients were female (67.9%) and 333 patients were male (32.1%). A total of 336 patients (32.3%) had one or more positive patch test reactions. The most common allergens were nickel (17.6%), cobalt chloride (5.3%), potassium dichromate (4.6%), neomycin (2.4%), fragrance mix (2.1%) and balsam of Peru (2.1%). Contact sensitivity to potassium dichromate and thiuram was significantly more frequent in male patients, whereas nickel and primin sensitivity was significantly more frequent in female patients. Higher sensitivity rates for potassium dichromate, neomycin, balsam of Peru, wool alcohol, fragrance mix and primin were noted in patients over 40 years of age. Sensitivity rates of the standard series allergens were all similar in atopic patients and in non-atopic patients. Metals, neomycin and fragrances are the leading allergens in Turkey. Although fragrances are among the most important sensitizers, sensitivity rates to fragrances and also to preservatives are much lower than the rates in Europe and the US.
Background:In pemphigus, autoantibodies are directed against adhesion molecules, which make the junctions between keratinocytes, and thus determining their level can reflect the disease activity.Aim:The purpose of this study is to determine the clinical significance of the autoantibody levels in pemphigus management.Materials and Methods:The clinical features of 47 pemphigus vulgaris patients were assessed and patients′ sera were investigated by indirect immunofluorescence using monkey esophagus as a substrate for autoantibody levels.Results:We found a significant correlation between antibody titers and mucosal severity scores. Initial antibody titers of the patients with at least one mucosal lesion at the end of the first month of the therapy were found significantly higher than the patients who had no mucosal lesion. With the therapy, lesions resolved earlier than the antibody titers.Conclusion:In patients with pemphigus, especially in cases who were not treated before, sera antibody levels are a valuable tool in evaluating disease severity and choosing initial treatment. In patients who had been taking any systemic treatment, it is difficult to make a relationship between antibody levels and disease severity, because therapy improves disease earlier than the antibody titers. However, estimating antibody levels can be helpful for clinicians in disease management, in reducing or ceasing treatment dosage and anticipating recurrence.
A 35‐year‐old housewife presented with an 11‐year history of a painless lesion on the right cheek, which had enlarged over the last 2 years. She had no history of travel or trauma. Various topical and systemic antimicrobial and antifungal agents, such as fluconazole, ketoconazole, sulbactam/ampicillin, and mupirocin, had been prescribed, with a probable diagnosis of pyoderma and blastomycosis, without significant benefit. Her medical history was otherwise unremarkable. Dermatologic examination revealed a well‐circumscribed, erythematous, infiltrative, 8 × 10 cm plaque covering the right cheek and a 2 × 3.5 cm vegetative, ulcerated lesion on the chin (Fig. 1). There were no sinus tracts or grains. 1 Erythematous, infiltrative plaque covering the right cheek, and vegetative, ulcerated lesion on the chin The following laboratory test results were within the normal limits: complete blood count, blood biochemistry, urinalysis, immunoglobulins and complement levels, T lymphocyte, CD4 and CD8 cell counts, and response to mitogens. X‐Rays of the chest and maxillar and mandibular bones were normal. Routine bacterial cultures were negative. Skin biopsies and fungal and mycobacterial cultures were taken with a preliminary diagnosis of deep fungal or mycobacterial infection. Dermatopathologic examination revealed irregular epidermal hyperplasia with follicular plugging. A dense nodular lymphohistiocytic infiltrate was observed within the reticular dermis, with many multinucleated giant cells and plasma cells. In higher magnification, even in hematoxylin and eosin sections, large septate hyphae and spores were noticeable. Periodic acid–Schiff stain revealed abundant fungal structures within the giant cells and extracellularly throughout the inflammatory infiltrate (Fig. 2). Lymphocytes were rather sparse in comparison to the large amount of microorganisms within the tissue. 2 Periodic acid–Schiff‐positive hyphae with phialides and yeast‐like phialoconidia (arrow) within the tissue (× 400) Fungal cultures were performed on Sabouraud's dextrose agar and, within 1 week of incubation, white fungal colonies were observed. On multiple passages at 26 °C, white tufted colonies with a salmon‐colored base had formed (Fig. 3). Native preparations from the cultured colonies revealed septate hyphae, and 90° angled branches, together with phialides decorated with ellipsoidal conidia with rounded edges (Fig. 4). These findings were consistent with Acremonium strictum, a saprophytic fungus. 3 Fungal culture: salmon‐colored base of the colonies 4 Lactophenol cotton blue (× 40): 90° branching septate hyphae with ellipsoidal, round‐ended conidia Further laboratory examinations revealed no systemic involvement. Following the diagnosis of Acremonium infection, amphotericin B therapy and surgical excision of the tumoral lesion were planned, but the patient refused further treatment and failed to respond to our follow‐up attempts.
We report on a 31-year-old female patient with systemic lupus erythematosus (SLE) for 24 years who had a past history of skin tuberculosis (lupus vulgaris), long-term corticosteroid therapy, and IgG deficiency. She presented with monoarthritis and concomitant meningitis from skin tuberculosis after 5 years. The diagnosis of joint and meningeal tuberculosis was defined with clinical symptoms--signs and typical histopathological findings of involved synovium. Clinical improvement was achieved with antituberculous therapy. Cutaneous, articular, and cerebral manifestations of tuberculosis might have been confused with some of the lupus manifestations or lupus activation. It should be kept in mind that tuberculosis may be encountered in SLE due to the nature of the underlying disease and/or its therapy. It is also worth mentioning that, in this patient, tissues involved with extrapulmonary tuberculosis were the primary areas of involvement with SLE.
