Delay of insulin therapy in type 2 diabetics.

Type 2 diabetes (T2DM) is a progressive disease. Insulin appears early in the therapeutic intensification algorithm, but is still a last resort. This delay is frequent but its duration has been little studied in the Tunisian population.

[Pseudo pheochromocytoma induced by professional stress: A case report].

Introduction: An elevation of plasma or urinary catecholamines or their metabolites in the context of a suspicion of a secondary hypertension associated with paroxysms generally leads to the diagnosis of pheochromocytoma. However, this is not always true.

Case Report: We report the case of a 39-year old man with a severe hypertension that was resistant to drug therapy and associated with paroxysms.

Methylenetetrahydrofolate Reductase (MTHFR) (C677T and A1298C) Polymorphisms and Vascular Complications in Patients with Type 2 Diabetes.

Objectives: To assess whether 2 polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) gene, C677T and A1298C, are risk factors for vascular complications in Tunisian patients with type 2 diabetes mellitus.

Methods: The MTHFR polymorphisms were genotyped, and plasma homocysteine levels were evaluated in 160 Tunisian patients with type 2 diabetes mellitus.

Results: Prevalence of the 2 heterozygous polymorphisms of the thermolabile MTHFR gene (CT and AC) was encountered more commonly in patients with diabetes mellitus than in the healthy controls (p<10).

[Association of renovascular hypertension and primary aldosteronism].

Introduction: Renal artery stenosis is rarely associated with Conn adenoma.

Case Report: We report a 27-year-old male patient who presented in 2001 with a severe high blood pressure associated with hypokaliemia. Radiologic investigations showed a left renal artery stenosis with agenesis of left kidney.

[Rupture of the excretory urinary tract due to a lithiasis of the pelvic ureter].

A case of rupture of the urinary tract related to lithiasis of the pelvic ureter is reported. Outcome was favorable after percutaneous drainage of the urinoma and removal of the stone using a Dormia catheter. Clinical diagnosis was readily established on the patient's history and on ultrasound and intravenous urogram findings.
