Clinical Experience with an Oral Diuretic,Trichlormethiazide

The main objective of this study was to observe the long-term effects of the administration of trichlormethiazide on the urine and blood. Fourteen patients suffering from essential hypertension or edema requiring diuretic therapy were treated for periods of one to 12 months (mean 5.4 months). There were no significant changes in urine values, blood counts, or serum sodium or potassium levels. Additional nitrogen retention occurred in two patients with renal failure, but no significant changes in blood urea nitrogen occurred in the remainder. Serum uric acid levels were lower at the end of treatment than before. The blood pressure fell in nine patients. No toxic effects were observed.     

SCA8 RAN polySer protein preferentially accumulates in white matter regions and is regulated by eIF3F

Spinocerebellar ataxia type 8 (SCA8) is caused by a bidirectionally transcribed CTG·CAG expansion that results in the in vivo accumulation of CUG RNA foci, an ATG‐initiated polyGln and a polyAla protein expressed by repeat‐associated non‐ATG (RAN) translation. Although RAN proteins have been reported in a growing number of diseases, the mechanisms and role of RAN translation in disease are poorly understood. We report a novel toxic SCA8 polySer protein which accumulates in white matter (WM) regions as aggregates that increase with age and disease severity. WM regions with polySer aggregates show demyelination and axonal degeneration in SCA8 human and mouse brains. Additionally, knockdown of the eukaryotic translation initiation factor eIF3F in cells reduces steady‐state levels of SCA8 polySer and other RAN proteins. Taken together, these data show polySer and WM abnormalities contribute to SCA8 and identify eIF3F as a novel modulator of RAN protein accumulation.     

Prise en charge actuelle des ejaculations retardees et des anejaculations psychogenes

The authors have reviewed their management of 220 patients presenting with retarded ejaculation or psychogenic anejaculation between 1973 and 1992. There are three current management approaches: mechanical treatment (vibrator massage); behavioural and cognitive therapy (relaxation, couple therapy) and psychotherapy, indicated when the problem is one of desire. Therapeutic intervention must procede in several stages in the most difficult cases: developing an awareness of subconscious defenses; rehabilitation and relaxation; and untervention at the couple level. This therapeutic strategy has led to a high success rate of 87% of cases, although it requires motivated patients and therapists committed to developing relationships of sexual harmony.
