[On fatal case acute ethyl alcohol poisoning (author's transl)].

A fatal case was reported of acute intoxication with ethyl alcohol, in which the alcohol levels were higher than any previously reported by Italian workers. On the basis of the normal blood alcohol curve patterns, in the case in question the absorption phase must have lasted longer than the hours usually considered as maximum for absorption of ethyl alcohol.

Renal adaptive mechanisms in aged and hypertensive humans: possible effects of treatment.

BACKGROUND: In the aging kidney renal blood flow and glomerular filtration rate are reduced due to glomerulosclerosis. On this regard, hypertension has synergistic effects and may lead to end-stage renal disease in a significant proportion of cases. MATERIAL AND METHODS: To study the effects of antihypertensive drugs in an acute setting, we expressly designed an acute experiment to assess the renal response to mental stress (MS). In healthy elderly, the response was characterized by a prolonged and pronounced renal vasoconstriction, due to a reduction in renal autacoid modulatory capacity, particularly of prostaglandins. In older patients with isolated systolic hypertension, the response to MS was impaired, being characterized by a passive vasodilation with hyperfiltration. The effects of antihypertensive drugs were evaluated twice in adults patients with mild to moderate essential hypertension: after two weeks of pharmacological wash-out and after two weeks of treatment with the ACE-inhibitor trandolapril (4 mg), or the non-dihydropyridinic Ca2+ channel blocker verapamil (240 mg), or both (2 mg + 180 mg). RESULTS: While the three antihypertensive regimens reduced blood pressure to a similar extent, their effects on the renal response to MS were different. Each regimen re-established a renal vasoconstrictive response to adrenergic activation. However, with trandolapril, renal vasoconstriction was limited, as it occurs physiologically, to the period of blood pressure rise, while verapamil, or the combination of the two drugs, were associated with more prolonged vasoconstriction. CONCLUSIONS: Further studies are needed to confirm the nephroprotective effects of these drugs, particularly of ACE-inhibitors. These data may be a pathophysiological basis for future clinical trials.

[Importance of the determination of fructosamine in monitoring diabetic patients].

Protein glycosylation plays a role in the metabolic control and in the pathogenesis of diabetic complications; indeed it has an important role in the process leading to micro- and macroangiography in diabetes. In an attempt to determine the clinical value of fructosamine assay for monitoring type II diabetic patients, the correlation of fructosamine and HbA1c, glycemia, cholesterol and triglycerides was studied. The results show that fructosamine is a good index for short-term metabolic control of diabetic patients.

[Clinical use of growth hormone and clonidine in growth disorders].

The aim of this study was to investigate the effects of the recombinant human growth hormone and of the alpha-2 adrenergic agonist clonidine in three groups of prepuberal children with growth disorders. Three children with GH-deficiency were treated with 0.5 U kg/week i.m. of recombinant growth hormone; 13 children (7 with constitutional delay of growth and 6 with familiar short stature) were treated with 0.08 mg/m2/die per os of clonidine. The results confirmed the growth promoting effect of GH in GH-deficiency. Clonidine restored GH-secretion in children with constitutional delay, but had a very poor or no effect in familiar short children.
