Segmental renal hypoplasia and hypertension.

The association of hypertension with congenital renal hypoplasia (Ask-Upmark kidney) has been well established. A case is presented that clearly demonstrates the distinctive clinical, roentgenographic and pathologic features. An abnormal production of renin by the affected kidney suggested that the renin-angiotensin-aldosterone axis was involved in the genesis of the hypertension. Hypertension was cured by unilateral nephrectomy.

[Chronopharmacokinetics of dexamethasone in young subjects].

Dexamethasone chronopharmacokinetics was studied in six young subjects 20 to 30 years old. The randomized cross-over study consisted of evening (11.00 p.m.) or morning (08.00 a.m.) dose separated by a period of one week. After the evening administration of the drug, only Tmax (1.77 +/- 0.74 à 11.00 p.m. and 0.99 +/- 0.64 à 08.00 a.m.) and Cmax/Tmax were higher than those determined at 08.00 a.m. This difference might be related to a cyclic variation of the absorption phase of dexamethasone. Thus, in our study, the time of administration has only a weak effect on the pharmacokinetics of dexamethasone.

[Acute psychiatric syndrome and quinolones].

A case of Flumequine poisoning is described; a 13-year-old girl was admitted for a psychiatric syndrome. 3 hours after, seizures, coma, and metabolic disorders were observed. Infectious, encephalitic or diabetic diseases were suspected, but not confirmed. After 12 hours of a symptomatic treatment, the clinical status improved and the patient was discharged. At that time a tablet was found in her bedroom and a mas spectrographic analysis was positive for Flumequine. This case report is in agreement with previous observations and confirms the small therapeutic index of quinolone, and the absolute necessity to assess carefully a psychiatric diagnosis.
