Pseudo tumor pelvic actinomycosis revealed by colonic obstruction with hydronephrosis: Can extensive surgery be avoided? A case report.

Pelvic actinomycosis with an intrauterine device accounts for approximately 3% of all actinomycoses. It is a chronic infectious disease characterized by infiltrative, suppurative, or granulomatous inflammation, sinus fistula formation, and extensive fibrosis, and caused by filamentous, gram-positive, anaerobic bacteria called . The slow and silent progression favors pseudo tumor pelvic extension and exposes the patient to acute life-threatening complications, namely colonic occlusion with hydronephrosis.

[Oxidative stress in end stage renal disease: evidence and association with cardiovascular events in Tunisian patients].

We assessed oxidative stress in 35 chronic renal failure under conservative treatment (CRF), 50 hemodialysed (HD) and 30 renal transplant (RT) patients, and 31 age- and sex-matched healthy subjects. Compared to controls, CRF patients exhibited significantly higher conjugated dienes (139 +/- 37 versus 121 +/- 22 micromol/l) and LDL oxidation (126 +/- 65 versus 99 +/- 46 micromol/l). Glutathione peroxidase activity was decreased in CRF and HD (5.

Hyperhomocysteinemia is associated with deep venous thrombosis of the lower extremities in Tunisian patients.

Objectives: To test the association between hyperhomocysteinemia (HHC) and deep venous thrombosis (DVT) of lower extremities in Tunisians.

Design And Methods: This case-control study included 90 patients with DVT of the lower extremities and 160 healthy controls. Plasma homocysteine, vitamin B(12) and folate were determined using immunoenzymatic methods.

Classical and "non-classical" cardiovascular risk factors in Tunisian patients with end stage renal disease: prevalence and association with cardiovascular events.

This study was aimed to determine the prevalence of several classical and non-classical cardiovascular risk factors, and to test their association with cardiovascular events in Tunisian patients with end-stage renal disease. A total of 35 chronic renal failure, 50 hemodialysed and 30 renal transplant recipient patients and 31 healthy subjects were included. Hypertension, elevated plasma concentrations of total homocysteine, fibrinogen, C-reactive protein, and lipoprotein(a) were highly prevalent in patients, whereas, smoking, hypertriglyceridemia, hypercholesterolemia, hypoHDLemia, and hypoalbuminemia were less common.
