[Neurosensory hearing loss in children with acute and chronic otitis media diagnosed by the measurement of short-latency auditory evoked potentials].

The sensory component of acute otitis media, especially in children, has been poorly studied. In order to identify the importance of ERA for the diagnosis of the neurosensory component of hypoacusis associated with acute otitis media, we examined 56 children. In all the patients ERA were recorded, and in children over 3 years old tonal audiometry was performed.

[Cyclic nucleotide levels in the gastric juice of patients with recurrent duodenal ulcer].

Cyclic nucleotide content in the gastric juice of patients with duodenal ulcer recurrences was studied before and after reconstructive surgery and in remote periods. The basal secretion phase was characterized by an increased cyclic nucleotide concentration in gastric juice; histamine and insulin stimulation caused decrease in their concentration. After reconstructive surgery, acid production in the basal period decreased, while cyclic adenosine monophosphate concentration increased by more than 100 per cent.

[Remote results of the surgical treatment of peptic post-gastrectomy and non-healing ulcers and recurrent post-vagotomy ulcers].

Operations were performed on 130 patients with various forms of recurrent ulcers. An analysis of late results (up to 8 years) in 76 patients has shown that stable healing was achieved in most of the patients treated by all reconstructive and correcting methods. The most justified intervention for peptic postgastroresectional ulcers is thought to be resection which may be accompanied by truncal vagotomy.

[Morphofunctional evaluation of the results of reconstructive operations of gastroenteroanastomosis in peptic ulcer].

The mucosa of the gastric stump, abducting and adducting loops of small intestine in patients with peptic ulcers of gastrointestinal anastomosis has been examined with scanning, transmission electron and light microscopy, morphometry, and the study of secretion at various periods after reconstructive surgery combined with vagotomy. An increase of the number of chief and parietal cells in the gastric stump fundal glands, increase of the thickness of the mucosa due to the deepening of the crypts of the adducting and abducting loops of the small intestine, and alteration of the mucosal microrelief of the gastric stump and small intestine are noted in peptic ulcers of gastrointestinal anastomosis especially near the site of anastomosis. This is accompanied by an increase of mucosal secretory activity.

[Ligatures of gastrointestinal anastomoses and their role in postgastrectomy diseases].

The clinico-endoscopic investigations have shown the ligation fistulas observed in 2,3% of patients following operations on the stomach to give the clinical picture characteristic of the operated stomach gastrites. Sometimes they are complicated by hemorrhages. All the ligations must be ablated in one or several steps.
