Severe erythema nodosum due to Behçet's disease responsive to erythromycin.

A patient with severe erythema nodosum due to Behçet's disease is reported on here. Erythema nodosum lesions did not respond to classical treatments; however, they cleared after erythromycin treatment, which was prescribed for the treatment of coincidental erythrasma. Erythromycin treatment appears to be an effective treatment option in erythema nodosum. The hypothetical anti-inflammatory effects of erythromycin, besides its antibiotic properties, are reviewed and discussed to explain such a clinical improvement.

Coexistence of osteopoikilosis and discoid lupus erythematosus: a case report.

Osteopoikilosis is an uncommon, benign sclerosing bone dysplasia characterised by typical roentgenographic findings and usually seen in patients with dermatological problems. We report a case of osteopoikilosis and discoid lupus erythematosus presenting with skin and mucosal involvement, an association that has never previously been reported. We also discuss the differential diagnosis and the clinical pathologies accompanying osteopoikilosis in the literature.

Expression of cell-cycle related proteins in Helicobacter pylori gastritis and association with gastric carcinoma.

Helicobacter pylori (H. pylori) infection is associated with changes in epithelial turnover, through their significance of these in gastric carcinogenesis is still controversial. The purpose of this study was to determine the influence of H. pylori infection on cell proliferation and the relation with the cell-cycle regulators, and finally to provide insights into the mechanism by which H. pylori may lead to gastric carcinogenesis. We investigated Ki-67, p53, p21(Waf1/Cip1), cyclin D1 expression in 55 patients with H. pylori gastritis, and compared the results with patients those of non-H. pylori gastritis patients (n=21), gastric adenocarcinoma patients (n=8) and samples with normal gastric mucosa (n=12). Gastric biopsies were histologically evaluated for inflammatory reaction, intestinal metaplasia and atrophy according to the Sydney system. Overexpression of Ki-67, p53, p21(Waf1/Cip1) and cyclin D1 was found in H. pylori gastritis patients (32.7%, 10.9%, 20.0% and 7.3%, respectively), whereas only scattered expression in cells in the neck region of the crypts, but no overexpression was found in gastric antral epithelial cells in biopsy specimens from patients with non-H. pylori gastritis and noninflammed mucosa. A significant relationship was found between the grade of H. pylori colonization and Ki-67, p53, p21(Waf1/Cip1) and cyclin D1 expression. Expression was significantly higher in patients with intestinal metaplasia with atrophy, whereas no overexpression was found in patients without intestinal metaplasia with atrophy (p=0.05). H. pylori infection is associated with increased cell proliferation, increased epithelial DNA damage, and atrophy, which might contribute to the development of gastric cancer. Even if the exact mechanism has not been elucidated yet, our results suggest that H. pylori infection acts as a cofactor in gastric carcinogenesis.

A case of lichen planus-lupus erythematosus overlap syndrome with eyelid involvement.

PURPOSE: To report a case of lichen planus-lupus erythematosus overlap syndrome with eyelid involvement. Lichen planus and lupus erythematosus infrequently coexist in the same patients. Ocular involvement has rarely been reported for both diseases. CASE REPORT: We describe a case of lichen planus-lupus erythematosus overlap syndrome with eyelid involvement. Histopathologic and immunofluorescent studies were done on buccal, lip, left conjunctival, malar, auricular and scalp lesions. The immunopathologic features of the conjunctiva, buccal mucosa and lip were consistent with lichen planus, while those of the malar, auricular and scalp lesions favoured lupus erythematosus. RESULTS: The patient was successfully treated with hydroxychloroquine 200 mg/day and all lesions responded to therapy within weeks. CONCLUSIONS: This is a rare example of two coexisting autoimmune disease entities: lichen planus of the oral mucosa, lip, eyelid and discoid lupus erythematosus of the skin. To our knowledge, this is the first reported case of lichen planus-lupus erythematosus overlap syndrome with eyelid involvement.
