RESUMO
AIM: This study aimed to analyze acute renal failure in perinatal asphyxia (PNA) of term newborns in a sub-Saharan urban health center. PATIENTS AND METHODS: The study was prospective, conducted from 1st June to 30th November 2013 on term newborns hospitalized at the centre hospitalier universitaire pédiatrique Charles-de-Gaulle for PNA. Renal insufficiency (RI) was defined by a serum creatinine greater than or equal to 90 µmol/L. RESULTS: Eighty-five PNA cases were included, or 19.8% of newborns hospitalized in the study period. The sex ratio was 2.1. Thirty-eight newborns (44.7%) had RI. Their creatinine averaged 153.8±96.6 µmol/L. Twenty-six of 38 (68.4%) had brain damage in Sarnat stage 2 and 12 (31.6%) stage 3. Twelve newborns with RI (31.6%) had seizures. Transfontanellar echography revealed an abnormality in 30 cases (78.9%) of RI. Of the 38 newborns with renal failure, albuminuria was found in 21 cases (65.2%) and leukocyturia in 28 cases (73.7%). Renal function improved in 86.1% of cases. Newborns with initially normal serum creatinine had no RI during hospitalization. Six newborns (7.1%) died. CONCLUSION: This study showed that acute RI is common during PNA most particularly in newborns with severe neurological impairment. In our context, earlier support for women in labor could help prevent PNA and therefore newborn acute RI.

In order to investigate the effect of angiotensin receptor blockage (ARB) for the treatment on diabetic erectile dysfunction (ED), we used male Sprague-Dawley rats injected with 65 mg/kg streptozotocin to induce diabetes mellitus. The diabetic rats with ED were selected by hypodermic injection of apomorphine (APO) after 8 weeks of model setting. All rats were divided into four groups: G1 (normal control rats), G2 (diabetic rats treated with normal saline), G3 (diabetic rats treated with valsartan) and G4 (diabetic rats treated with spironolactone). After treatment with drugs for 8 weeks, the rate of erection for each group was evaluated after the injection of APO. The intracavernous pressure (ICP) of each rat was then recorded before and after the electrostimulation of the major pelvic ganglion. The rates of erection and the ICP after electrostimulation for diabetic rats treated with valsartan were significantly higher than that in diabetic rats treated with normal saline and spironolactone. The ARB may be an effective therapy for diabetics with ED.
