[Tobacco habits in a cohort of 4,135 adolescents attending high school in northern Italy. Results of a multicenter study].

Assuming that adolescence--a high risk age as far as this behavior is concerned--is the crucial stage for prevention procedures, we don't know much about Italian adolescents' tobacco related behaviors, regardless of the fact that tobacco smoking is one of the most relevant problems of Public Health. The goal of this research has been assessing, through a multicentric study using an anonymous questionnaire, how spread is this behavior among 4135 students attending high school in five different areas of Northern Italy. The research points out a remarkable spreading of the phenomenon and suggests to anticipate prevention procedures during compulsory education, taking in account gender features.

[Contribution of the serum anti-mycobacterial IgG measurement to the diagnosis of tuberculosis. Personal cases].

Data of a transversal research on 36 suspected tuberculosis (tb) inpatients of St. Luigi Hospital are reported. Serum antimycobacterial antibodies Class IgG to A60 were measured by means of ELISA. Final diagnosis was tb in 19 subjects, while 9 had a tb history over different years. Sensitivity was 78.94% and specificity 75%. According to with other recent reports, our results are poorly discriminating. However, the test, if valued with other clinical data, can contribute to the ascertainment of tb.

[Tolerability to terizidone (TZ) in the treatment of pulmonary tuberculosis in dialyzed patients].

Six dialysed patients affected by tuberculosis involving the respiratory apparatus were included in the study. Antimycobacterial treatment consisted of polychemiotherapeutic combinations using terizidone (TZ). The need to resort to this drug may be explained by the need to exclude normally used drugs (R/AMP, INH, SM) due to resistance, allergy or organ meiopragia. Five patients received terizidone at a dose of 600-900 mg/day for the entire course of treatment, whereas it was necessary to abandon treatment in one patient due to the onset of depressive symptoms which then rapidly regressed following the suspension of TZ therapy. The good level of tolerance demonstrated in the 5 remaining cases confirm the inclusion of this drug in the treatment of a limited number of cases of tuberculosis in dialysed patients.

[The current epidemiologic profile of the drug resistance of Koch's bacillus to antitubercular antibiotic chemicals].

The study was conducted on patients with initially diagnosed tuberculosis encountered in 1986-87. A series of 269 bacterial antibiograms performed on sputum [correction of excreate] and other materials was examined in order to ascertain the resistance of Koch's bacillus to R/AMP, INH, SM and EMB. Primary drug resistance was found in 64 cases (23.79% of the total) and was isolated in 32 (11.89%), multiple in the rest. The response to the individual antibiotics was a follows resistance to INH was isolated in 11 cases (4.08%), combined with resistance to other drugs in 27 (10.03%); resistance to SM was isolated in 13 cases (4.81%) multiple in 24 (8.92%); resistance to R/AMP was isolated in 4 cases (1.48%), multiple in 14 (5.2%); resistance to EMB was isolated in 4 (1.48%) multiple in 19 (7.06%). Comparison with earlier studies in the Turin area highlights that the incidence of TB, in decline up to 1979, significantly increased in the period considered.

Tuberculosis of the larynx. Today.

Forty-one cases of laryngeal tuberculosis accounting for 0.79% of the TB cases observed in 1975-85 are examined. The M/F ratio was 9.2:1; the mean age 52 years 9 months. In all cases current or earlier tubercular lesions on the pulmonary parenchyma were also noted. The laryngeal sites affected were as follows, in order of frequency: true vocal cords, epiglottis, false cords and laryngeal ventricles, arytenoid and interarytenoid area, subglottic area. The patients were treated with R/AMP, INH, EMB or SM, EMB with satisfactory results. Two cases required exeresis of laryngeal lesions and 3 tracheotomy.

The release of thromboxane B2 and 6-keto-PGF1 alpha following pulmonary embolism.

It has been shown in animals that acute obstruction of pulmonary artery branches is followed by an early but shortly lived increase in blood levels of thromboxane B2 and a subsequent longer-lasting increase in blood levels of 6-keto-PGF1 alpha. Our study was conducted on twelve patients with acute pulmonary embolism. Nine were treated with urokinase; three could not be given thrombolytic or anticoagulant drugs due to bleeding peptic ulcer (2 cases) or recent cerebral hemorrhage (1 case). HPLC and RIA tests were performed on arterial blood samples at diagnosis and after 1, 6, 12 and 24 hours. Findings were compared with those in a control group of 6 healthy subjects. There was a difference in prostanoid behaviour between the untreated and urokinase treated patients. Among the former mean TxB2 was significantly raised at clinical onset and began to decline after 6-12 hours, approaching the mean level found among the controls after 24 hours. In contrast 6-keto-PGF1 alpha was raised after 1 hour and gradually declined thereafter. In the subjects treated with urokinase TxB2 was already close to the mean control level after 1 hour; 6-keto-PGF1 alpha had increased after 1 hour but had returned near the control level after 12. The behaviour of prostanoids appears to match the clinical course.
