Deep Vein Thrombosis in Upper Limb in a Weightlifter.

Aim: We report an unusual case of a male weightlifter with upper extremity venous thrombosis.

Case Presentation: Thrombosis affecting subclavian-axillo-humeral venous trunk produced by the compression of these veins by the trained muscles of the shoulder girdle (Paget-Schroetter syndrome) has been reported. During the study, a renal carcinoma was detected.

Isolated testicular polyarteritis nodosa.

Isolated polyarteritis nodosa is a rare condition that may be triggered by local exposure to certain agents capable of provoking local immunostimulation without a systemic immune reaction. Isolated polyarteritis nodosa in the testes presents similar histologic characteristics as those of systemic inflammation, although infarcted areas in the testis are more common in generalized polyarteritis nodosa. Definitive diagnosis requires histologic study.

Effect of N-acetylcysteine on antioxidant status in glycerol-induced acute renal failure in rats.

Myoglobinuric acute renal failure has three pathogenic mechanisms: tubular obstruction, renal vasoconstriction, and oxidative stress. The latter is generated through the iron released from the group hemo of the myoglobin. Iron induces the formation of high-activity oxygen free radicals that increase oxidative stress and provoke lipid peroxidation and cellular death.
