Carboplatin and vindesine in advanced non-small cell lung cancer. A feasibility study.

Twenty-eight patients affected by advanced non-small cell lung cancer (NSCLC) were enrolled in a feasibility study evaluating toxicity and activity of carboplatin-vindesine combination chemotherapy, according to two different schedules. Fourteen patients were treated with carboplatin 350 mg/m2 monthly and vindesine 3 mg/m2 weekly for 5 doses, then every other week (schedule 1). The activity observed was promising with 3 partial remissions, but the toxicity was substantial, preventing full dose administration in 11 out of 14 patients. The subsequent 14 patients were treated with carboplatin 350 mg/m2 monthly and vindesine 3 mg/m2 on days 1 and 8 of each cycle. Activity was maintained with 4 partial remissions and toxicity was quite tolerable, allowing all patients to receive the planned treatment. The combination of carboplatin 350 mg/m2 on day 1 and vindesine 3 mg/m2 on days 1 and 8 seems active and well tolerated in advanced NSCLC patients and deserves further evaluation in a larger phase II study.

[Pharmacologic treatment of duodenal ulcer. Short and long-term results with pirenzepine in ambulatory patients]. / In tema di trattamento farmacologico dell'ulcera duodenale. Risultati a breve e lungo termine con pirenzepina in pazienti ambulatoriali.

Pirenzepine is an antimuscarinic drug highly selective for M1 receptors, which proved to be effective in the treatment of peptic ulcer. Aim fo the present study was to assess the frequency of relapses over a 12-month period subsequent to the anatomic healing of duodenal ulcer, obtained with pirenzepine (PRZ). Sixty patients (44 M, 16 F, mean age 42,9 years range 19-73) entered the study. They were allocated at random to a double-blind treatment with placebo or PRZ given at two different dosages, 50 or 100 mg/day respectively, over a consecutive period of 12 months. Clinical evaluations were foreseen every 3 months, while endoscopy and hematology, gastrin plasma levels and intra-ocular pressure assessment at the end of the 6th and 12th month. The intake of antacids or equivalent drugs, in addition to the baseline treatment, was not allowed. Statistical evaluation of the results was performed by chi-square test with Yates' corrections. Difference in percentage of patients without relapses at 6th month and at 12th month was clearly in favour of PRZ compared with placebo. Non changes in the indices of gastrin plasma levels, liver or renal functions and intraocular pressure were reported. No patients complained of side-effects pirenzepine-related. The treatment with full dosage (100 mg/day) did not increase the rate of positive responsiveness compared to that of standard dosage (50 mg/day). It might confirm the importance of the role played by nocturnal acid secretion. For this reason, a decrease in relapses could be expected with the dosage of 100 mg if it was given in a single evening dose. However, therapy with PRZ turned out effective and did not produce side-effects. Its selectivity avoided clinical effects related to a cholinergic system block.

[The role of infective intestinal complications on the course of Crohn's disease and ulcerative rectocolitis]. / Ruolo delle sovrapposizioni infettive intestinali in corso di morbo di Crohn e rettocolite ulcerosa.

The authors studied the incidence of protozoal and bacterial infection in 41 cases of Crohn disease und ulcerative colitis; the effect of anti infective therapy on the clinical course has also been tested. Patients with ulcerative colitis are more frequently involved in this type of complication than those with Crohn disease. Therapy has a positive influence on the course of the disease; therefore systematic study of the faeces for bacteria and parasites is necessary for a correct understanding of chronic inflammatory bowel disease and for specific treatment.
