Combined ranitidine and pirenzepine in the treatment of duodenal ulcer: a multicentre double-blind study using endoscopy.

The efficacy of a combination of ranitidine and pirenzepine in the short-term treatment of duodenal ulcer was evaluated in a double-blind trial. In a multicentre study, 352 patients with active duodenal ulcers were randomly allocated to be treated with 300 mg/day ranitidine plus placebo (group I), 300 mg/day ranitidine plus 50 mg/day pirenzepine (group II), or 300 mg/day ranitidine plus 100 mg/day pirenzepine (group III) for 4 weeks. The respective healing rates assessed using endoscopic examination after 2 and 4 weeks' treatment were 40% and 70% in group 1, 44% and 82% in group II, and 37% and 77% in group III. The differences between the treatment groups were not significant, although 300 mg/day ranitidine plus 50 mg/day pirenzepine tended to be superior to the other treatments. Analgesic activity was the same in the three groups with 33%, 34% and 33% reductions, respectively, in the numbers of patients experiencing pain after 2 weeks. Side-effects (mainly dry mouth and blurred vision) were significantly more frequent in group III patients.

[Electric abdominal epidutaneous findings in the pathology of colonic motility].

Abdominal epicutaneous electrical activity has been studied in a group of 58 gastroenterically normal subjects or suffering form colon motor pathology. An evident similarity of behaviour was observed in the various groups: 17 out of 18 subjects with irritable colon and 6 out of 7 with subocclusion of the colon presented waves with characteristic amplitude and frequency. This type of electrical activity was present in only 1 normal subject out of 20; 11 patients with paralysis of the colon did not present waves of note; three patients with ulcerative colitis showed behaviour similar to the majority of the normal subjects. The technique illustrated would appear adequate for the study of colon pathology with motility alterations.

[Lithium poisoning and the use of nimesulide].

We describe a case of lithium intoxication, complicated by renal failure in a lithium treated women. She would take nimesulide, a selective cyclo-oxygenase-2 inhibitor, used in a variety of inflammatory, pain and fever states. This is the first report of the accumulation of lithium caused by nimesulide.

[Postoperative infections: the use of thymostimulin (TP1) in patients at risk].

The authors report data related to 212 surgical patients at risk because immunocompromised. Patients were divided in two homogeneous groups, one treated with Thymostimulin and the other as a control group, all affected by severe pathologies. Patients presenting postoperative complications directly related to technical reasons were excluded. Morbidity, postoperative hospitalization and mortality were the parameters considered. Positive results were obtained in the treated group compared to controls. Therefore, it is Authors' opinion that the treatment with Thymostimulin in immunocompromised patients is important in order to avoid or reduce postoperative infection rates.

[Efficacy of medical therapy in preventing the post-surgical recurrence in Crohn's disease].

Crohns Disease (CD) is a chronic intestinal inflammatory disease of unknown origins that cannot be definitely resolved with surgical intervention. Therefore, pharmacologic therapies are of great importance both in preventing relapses and by determining remissions. In this paper the authors analyse the different drugs available for the treatment of Crohns disease, and focus on their efficacy and tollerability.

Action of glucomannans on complaints in patients affected with chronic constipation: a multicentric clinical evaluation.

Chronic constipation is a very frequent disease in western countries but fibres can often solve the problem. In the present study, authors tested the efficacy and the acceptability of glucomannans, hydrophylic carbohydrates with a high degree of viscosity, in 93 patients affected with chronic constipation. The multicentric, open and non-controlled study was divided into an initial phase (treatment with 1g of glucomannans t.i.d. for 1 month) and a maintenance phase (1g b.i.d. for one month). We evaluated both objective parameters (number of days per week with bowel movements and number of enemas) and abdominal symptoms. After one month all assessed parameters showed a statistically significant improvement lasting through the second month. Glucomannans were well accepted and devoid of relevant side-effects. In conclusion, considering their efficacy and tolerability, they can be proposed as an ideal therapeutic tool in the management of chronic constipation symptoms.

[Latero-cervical metastasis of N0 laryngeal cancer].

The authors report a pathological study of functional neck dissection performed on 145 N0 laryngeal carcinoma patients from 1982 to 1988. The incidence of occult latero-cervical metastases in N0 was evaluated in relation to site and extension of the primitive tumor. A total of 108 supraglottic, 25 glottic and 12 transglottic tumors were observed. Among the cases treated the incidence of occult metastases was 28.3% while capsular rupture accounted for 3.4%. Diagnostic error, calculated on the number of neck dissections, was 20.2%. A greater incidence of occult metastases was found in supraglottic tumors (29.6%) than in either glottic (24%) or transglottic (25%) tumors. Furthermore, incidence of occult metastases proved proportional to the extension of the primitive tumor. There was a single metastases in 35 cases while only 6 cases proved multiple. Some final considerations are given on the importance of performing precautionary functional neck dissection in N0 laryngeal cancer.

[Clinical significance of HDL-cholesterol variations in viral hepatitis].

40 patients suffering from acute viral hepatitis, 18 type A, 18 type B and 4 non-A non-B have been examined. During the acute phase there was a marked reduction in HDL cholesterol (average 4.4) with subsequent steady increase up to 16.6 at the 5th week of disease. A highly significant negative correlation was observed between transaminases and direct bilirubin. There was no correlation with prothrombin activity, phospholipids and albumin. The clinical significance of these data is discussed.
