[Multiple carcinomas: considerations on several cases with synchronous/metachronous involvement of the respiratory tract]. / Carcinomi multipli: considerazioni su alcuni casi a coinvolgimento sincrono e/o metacrono delle vie respiratorie.

The authors report their observations on 7 cases of multiple malignant tumors during the period 1988/1992 (frequency of 0.03 x 100). They report that primary malignant tumors involved the laryinx and the wang, and both the lungs in a synchronous or metacronous way. They suggest that pathogenesis of multiple malignant tumors may be very similar to that of multiple endocrinous neoplasms.

Levodropropizine in the premedication to fibrebronchoscopy.

The aim of the study was to evaluate the efficacy of cough-preventing treatment with levodropropizine, a drug inhibiting peripheral cough reflexes, in patients undergoing bronchial endoscopy. Sixteen patients, aged 37-73 years, suffering from chronic obstructive lung disease in the hypersecretory phase, were included in the study. The experiment was designed as double blind with double observer, controlled versus placebo. As comparative efficacy parameters were considered the number of anaesthetic boluses (lidocaine at 2%) administered during and immediately after the manoeuvre. The number of coughs during and 10 min after bronchoscopy was registered on a magnetic tape and read by a blinded observer thereafter. Levodropropizine was given as oral drops (20 each time, equal to 60 mg active drug) 12 h and 1 h before bronchoscopy. Data analysis was performed by descriptive statistical tests and by the non-parametric Wilcoxon test for paired samples. Levodropropizine treatment significantly reduced the number of anaesthetic enemas (p less than 0.01), and presented an excellent tolerability and safety profile.

[Diagnostic role of BAL in pulmonary alveolar microlithiasis]. / Ruolo diagnostico del BAL nella microlitiasi alveolare polmonare.

From 1982-90, 3721 fiber bronchoscopies were performed for the diagnostics of diffused alveolar-septal pathologies; BAL was performed in 400 cases. Alveolar pulmonary microlithiasis was diagnosed in 6 patients, and two of them were related. The staging and the evolution of the pathology were evaluated as follows: chest x-ray in various projections, calcemia, lung function tests, fiber bronchoscopy with analysis of BAL and quantitative evaluation of macrophagic and lympho-monocytic elements and in percentage of calcosferitics. Four patients were treated with therapeutic BAL in the lungs with normal saline, and the cytological results and the percentage of calcosferitics were monitored for 24 months.

[Cefotetan treatment of suppurative bronchopulmonary syndromes sustained by anaerobic germs]. / Trattamento con cefotetan delle sindromi suppurative bronco-polmonari sostenute da germi anaerobi.

The Authors have analyzed the effect of Cefotetan in 20 patients affected by bronchopulmonary pathologies supported by anaerobic bacterium. During 7 days doses of 50 mg. pro Kg/pro die were given. From beginning to end of the treatment clinical, hematochemical and radiological data were evaluated. Bacteriological analysis was made on samples drawn with BFS according to a traditional method and with microbiology specimen brush. Almost all the patients (95%) realized improvements in clinical symptomatology and in radiological picture.

Alterations of the endoalveolar surfactant after surgery with extracorporeal circulation.

In 10 patients who required extracorporeal circulation (ECC) during surgery, we studied the damage induced by surgery to the pulmonary surfactant and the effectiveness of ambroxol in preventing changes in the phospholipid pool. There were 5 control patients and 5 patients who were given 1 g/day of ambroxol on the 4 days prior to and the 4 days after surgery. To follow changes in phospholipid concentrations, bronchoalveolar lavage (BAL) was performed before surgery and 24 h and 8 days after ECC. Phospholipids were assayed in the BAL liquid by two-dimensional thin-layer chromatography. There were marked decreases in total phosphorus and quantitative alterations of individual phospholipid species in the surfactant of the control group, but not in the patients treated with ambroxol.

[Incidence of cefotetan sensitivity in anaerobic microbes responsible for acute and chronic relapsing bronchopneumonia]. / Incidenza della sensibilità al cefotetan di germi anaerobi responsabili di broncopneumopatie acute e croniche riacutizzate.

Bronchial fluid samples obtained from 50 patients with respiratory tract infections were analyzed for anaerobic flora isolation, identification of micro-organisms and evaluation of their sensitivity to cefotetan. Anaerobic strains were identified in 18 patients (36%), generally with exacerbations of chronic diseases: cefotetan was active on 100% of isolates.
