A description is given of the etiology and pathology of intramural esophageal diverticulosis as so far discussed in the literature. In view of the course and the clinical findings in two young patients in whom this diagnosis was established, it is suggested that intramural diverticulosis develops as a result of a devolopmental disorder in the autonomic nervous system.

A comparison between the mucosal pathology of the respiratory tract in cases of viral infections and of iatrogenic trauma after bronchoscopy and tantalum bronchography indicates that the respiratory mucosa has a very high degree of resistance against infection after trauma and is capable of rapid regeneration as long as the production of mucus continues and the surface remains moist. Viral infection might primarily inhibit mucus production and open the road to secondary infection.

Four groups of 8 patients undergoing bronchoscopy were premedicated with either pentobarbitone 1 mg/kg i.m. followed by i.v. saline, or diazepam 10 mg and saline i.v., or diazepam 10 mg i.m. followed by diazepam 20 mg i.v. and, diazepam 20 mg i.m. and then saline i.v. Both the patients and the bronchoscopist were asked to score the premedication as excellent, satisfactory, unsatisfactory or bad. Plasma cortisol was measured before premedication and before and after bronchoscopy. Preoperatively plasma cortisol increased in every group except that given diazepam 20 mg i.m., and during bronchoscopy it rose in all except the group who received 20 mg diazepam i.v. In patients who considered the premedication unsatisfactory, the rise in plasma cortisol from before premedication until after bronchoscopy was significantly higher than in satisfied subjects. It appears that in patients undergoing bronchoscopy higher doses of diazepam (20-30 mg) gave better suppression of stress than 10 mg diazepam, or 1 mg/kg pentobarbitone.

A new electroscope has been designed from the conventional Haslinger tubes. The new rigid scope combines the advantage of air insufflation in the flexible system with the therapeutic possibilities of the rigid tubes and is trustworthy in the following esophageal procedures; a) finding entrance of severe strictures; b) introducing nasogastric feeding tubes; c) extraction of foreign bodies; d) tumor coagulation/spur in hypopharyngeal diverticuli; e) washing and suction in cases with severe food retention; f)making tumor smears in patients with clotting disorders; g) taking substantial biopsies with an optical forceps, and h) objective photodocumentation of esophageal pathology.
