Antinucleosome in systemic lupus erythematosus. A study in a Brazilian population.

Antinucleosome antibodies have been found with variable prevalence in systemic lupus erythematosus (SLE) and were associated with more severe disease. This research aims to study the prevalence of antinucleosome antibodies in a sample of Brazilian adult SLE patients and their association with clinical findings and disease activity. Ninety-two adult patients (81 females and 11 males, with mean age of 37.

Leg ulcers and anticardiolipin antibodies.

Prothrombotic phenomena are described in leg ulcers of different etiologies. This work attempts to verify the prevalence of anticardiolipin antibodies in such patients. For this purpose, 151 patients with leg ulcers and 150 control patients were studied and it was obtained clinical data and anticardiolipin antibodies titers.

Porphyria cutanea tarda and systemic lupus erythematosus.

The co-existence of systemic lupus erythematosus and porphyria although rare has been known for a long time. This association forces the physician to make a careful differential diagnosis of the bullous lesions that might appear in such patients and to be careful when prescribing certain drugs such as chloroquine. This drug, when used in the regular doses for treating lupus, may cause hepatotoxicity in patients.

Acquired unilateral nevoid telangiectasia in a healthy men.

Unilateral nevoid telangiectasia is a rare vascular dermatosis, characterized by areas of superficial telangiectases distributed in a linear unilateral pattern. It was described in 1899 by Zeisler and Blascko. Several theories where developed in order to explain its etiopathogenesis.

Evaluation of healing prosthetic materials polyester mesh resorbable film and collagen elastin matrix /polypropylene used in rabbits abdominal wall defects.

Purpose: To compare polyester with absorbable layer prosthesis with collagen-elastin/polypropylene prosthesis in the repair of abdominal wall defects.

Methods: The 16 studied rabbits were divided in groups A and B (euthanized on the 30th and 60th days, after the implant of the mesh). The animals underwent laparotomy and received a 2 cm wall 'defect' on each side of the Alba linea.
