Pyoderma Gangrenosum - a Challenging Diagnostic Approach.

Pyoderma gangrenosum (PG) is an infrequent, aseptic neutrophilic dermatosis that can be observed in patients with systemic diseases such as inflammatory bowel disease or rheumatic disorders. Due to its rare entity, PG often constitutes a diagnostic enigma, as it simulates other skin disorders. Typically, it is displayed as painful, ulcerative lesions localized to the lower extremities.

Electrocardiographic abnormalities in patients with novel H1N1 influenza virus infection.

The cardiac effects imposed by the novel H1N1 influenza strain have not been elucidated until now. Electrocardiographic (ECG) abnormalities were evaluated in a series of 50 patients with confirmed novel H1N1 influenza infection. Epidemiologic and clinical characteristics, laboratory correlations, and the effect ECG abnormalities may exert on disease outcomes were prospectively studied.

The liver in brucellosis.

Background & Aims: Brucellosis involves the liver in varying ways, ranging from benign subclinical increases in serum aminotransferase levels to ominous chronic suppurative disease. Data on histopathology of the liver in brucellosis are scarce and contradictory. We sought to determine the liver histologic patterns present in a series of brucellosis patients and review the existing knowledge about liver involvement in this worldwide, prevalent zoonotic infection.

Long-term follow-up of patients with adult-onset Still's disease.

Objective: To evaluate the long-term outcome of patients with adult-onset Still's disease (AOSD).

Methods: Eleven patients with AOSD who were regularly followed-up during the past 13 years, even after discontinuation of treatment, were evaluated for the long-term prognosis of the disease and its possible complications.

Results: No exacerbation of the symptoms was noted during therapy.
