ABSTRACT

From 1987 to 1991, a seroepidemiologic survey for antibodies to hantaviruses, leptospira, rickettsiae, and Borrelia was conducted in selected Italian population groups. In the mountainous areas of northeastern Italy, the prevalence of antibody to hantaviruses, as detected by indirect immunofluorescent antibody (IFA) assay, was 7.1%, 4.8%, 4.3%, and 4% in 265 forestry workers, 82 rangers, 395 farmers, and 75 hunters, respectively. Among 299 Alpine soldiers, the prevalence was lower (0.7%). Of those with Hantaan antibody, the reactivity pattern using Hantaan, Puumala, and Fojnica viruses suggested a prevalence of antibody to Hantaan virus, with titers reaching levels of 128. The presence of leptospiral antibodies (by microagglutination test), which included the prevalence of antibodies to Leptospira icterohaemorrhagiae, L. bratislava, and L. saxkoening serotypes, was observed in 10-12% of the farmers and forestry workers in these Alpine mountain regions. Only a few sporadic clinical cases of leptospirosis have been reported from these regions. Antibodies to Borrelia burgdorferi (by IFA) were observed in 19% of the rangers and forestry workers, with lower values in farmers (10%) and hunters (8%). These data suggest the presence of a large number of asymptomatic infections with B. burgdorferi and the leptospires in the densely wooded areas of the Alpine Italian regions. Furthermore, the recent identification of a case of Hantaan acute nephropathy in a man living in the mountainous northeastern area of Italy confirms the presence of hantavirus in the Italian Alpine zones, especially those near the Slovenian border.

ABSTRACT

A form for recording acute toxicological cases has been preliminarily applied to a sample of 436 subjects admitted during 1978 into the hospitals of two districts of the Venetian Region. One was predominately manufacture and industry, and the other a mountain-agricultural area. The latter had medical facilities less uniformly distributed. Through epidemiological analysis, the acute poisoning cases from psychoactive drugs (benzodiazepines, barbiturates, antipsychotic agents, and tricyclic antidepressants) prevailed (37.9%). They were followed by acute cases from street heroin or other opiates in addicts (25.7%) that only occurred in the main town of the more industrialized district. The incidence of the other poisoning cases were in the following decreasing order: household poisons (9.8%), nonnarcotic analgesics (5.1%), agricultural poisons (4.1%), cardiovascular drugs (3.7%), miscellaneous drugs (1.4%), food and plants (1.4%), oral contraceptives (1.0%), viper envenomization (0.7%), and insect bites (0.7%). A rate of 8.5% was due to unidentified compounds. Mortality was 0.9% and death occurred after exposure to corrosives, carbon monoxide, or undetermined substances. Between the two districts there were no marked differences in emergency and general measures that mainly consisted in supportive treatment with forced diuresis (13.9%) and gastric lavage (only 21.4%).

ABSTRACT

Cardiotocographic variations certainly attributable to epidural anaesthesia were studied over the period 1972-1980 on 716 patients in labour. Transitory side-effects due to both direct and indirect action of local anaesthetics appeared in 1.4% of the cases, without, however, subsequently creating any particular foeto-newborn problem. On the basis of the experience acquired, it seems justifiable to affirm that the correct use of continuous epidural block, affected by very small doses of bupivacaine (10-20 mg per administration) is almost risk-free. The only inconvenience therefore that may sometimes arise would only be due to the relevation of a concealed cava occlusion when the maintenance of a left lateral position is not observed.
