Intrathecal dermorphine in postoperative analgesia.

The effectiveness of intrathecal morphine (500 micrograms), intrathecal dermorphine (20 micrograms) and routine intramuscular pentazocine (30 mg) in the relief of postoperative pain, was compared in 150 consecutive patients after elective surgery, in a prospective randomized double blind study. The analgesic effect of intrathecal dermorphine was found to be profound and to last significantly longer (43.41 +/- 1.64 hr) than intrathecal morphine (34.45 +/- 2.35 hr) or the routine pentazocine therapy (10.79 +/- 2.23 hr). The mean postoperative hospital stay in the intrathecal dermorphine (5.6 +/- 4) and morphine groups (6.3 +/- 45) was significantly shorter than in the control group (8.7 +/- 42). Side-effects, as urinary retention, vomiting and headache, were not significantly different in the three groups of patients.

Nutritional effects of total gastrectomy. A prospective randomized study of Roux-en-Y vs Longmire-Mouchet reconstruction.

A prospective randomized study was carried out to evaluate the nutritional and clinical results of two reconstructive procedures after total gastrectomy for gastric cancer: Longmire-Mouchet (LM) operation with loop interposition and maintained duodenal transit and Roux-en-Y (RY) reconstruction with duodenal exclusion. 22 patients, 11 with LM reconstruction and 11 with RY reconstruction were studied pre-and postoperatively. The average follow-up was of 30 +/- 8 months. The clinical results were shown to be substantially similar to the two groups. No patients complained of heartburn or dysphagia. At esophagoscopy no signs of esophagitis were detected in both groups. The two time course curves of body weight variation did not show statistically significant differences even though in RY patients the body weight has reverted more rapidly to basal values.

Prostaglandins in commercial milk preparations. Their effect in the prevention of stress-induced gastric ulcer.

To determine if prostaglandins might be the gastroduodenal mucosal protective components in milk, concentrations of prostaglandin E2 (PGE2), thromboxane B2, and 6-keto-PGF1 alpha (the major metabolite of prostacyclin) were measured in aliquots of commercial milk. Whole milk, heavy cream, and yogurt each contained more than 3 ng/mL of PGE2, whereas low-fat milk (2.04 +/- 0.18 ng/mL) and milk from three nursing mothers (0.66 +/- 0.05 ng/mL) contained substantially less. Levels of thromboxane and prostacyclin were much lower, in general, less than 500 pg/mL. In a cold-restraint stress ulcer model in rats, milk was able to inhibit the development of gastric ulcers (50% and ulcer index 5.0 +/- 2.1 v control, 90% and 18.9 +/- 3.8, respectively). Charcoal treatment, which depleted more than 95% of the prostaglandins, rendered the milk nonprotective (80% and ulcer index 15.0 +/- 1.4). These observations are consistent with the concept that prostaglandins may be responsible for the presumed beneficial effects of milk in the prevention and treatment of peptic ulcer disease.

ABO blood groups and serum gastrin.

Serum gastrin concentrations were measured in 75 subjects of blood group O and in 75 subjects of other blood groups. Gastrinaemia both basally and following stimulation by glycine drink or by insulin hypoglycaemia did not show any statistically significant differenc in blood group O people as compared to subjects of other blood groups. It is concluded that the claimed relationship between blood group O and parietal cell hyperplasia cannot be considered as secondary to a relationship between blood group O and increased gastrin-producting G cell mass.
