[Bleeding non-epithelial gastrointestinal neoplasms]. / Krovotochashchie neépitelialnye opukholi zheludochno-kishechnogo trakta.

Inefficiency of x-ray and endoscopic examinations of a bleeding hollow organ of the gastrointestinal tract may be explained by the effection of its wall with nonepithelial tumor (lipoma, neurinoma, leiomyoma). In some cases only laparotomy and examination of the abdominal cavity succeed in localization of the tumor. Intraoperative cytodiagnosis of nonepithelial benign tumors is a method conducive to sparing surgery (partial resection, dissection).

[Granular otitis externa]. / Granuliruiushchii naruzhnyi otit.

These authors examined 18 patients with granular external otitis. As other clinicians, the authors believe that the disease should be viewed as a separate nosological pathology. In the case of granular myringitis it is important to differentiate between this disease and chronic suppurative otitis media complicated with polyps or granulations. The granular tissue on the walls of the external acoustic meatus can develop due to inflammation of the skin alone without periosteum or bone involved. It may also occur as a result of suppurative osteoperiostitis of the external acoustic meatus. This pathology also requires differential diagnosis because different therapeutic approaches are to be applied.

[Potentiation of the antimicrobial action of antibiotics in combination with oxytocin]. / Usilenie antimikrobnogo deistviia antibiotikov v kombinatsii s oksitotsinom.

The antimicrobial effect of oxytocin in combination with 39 antibacterial drugs was studied in vitro with the use of 30 strains of different test cultures. It was shown that oxytocin had a capacity for potentiating the antibiotic effect on many microbial species. The potentiation ratio depended on the antibiotic and microbial species used and ranged from 2 to 24 times. The combined therapy with oxytocin and antibiotics was tested on animals with experimental staphylococcal sepsis. The survival rate of more than 50 per cent was observed only in the group of animals treated with the combinations of antibiotics and oxytocin, while in the other groups the death rate amounted to 100 per cent. The most favourable combinations of oxytocin and antibiotics were used in the treatment of 260 patients with pyoinflammatory affections of the soft tissues (mastitis, postinfection suppuration, paraproctitis, etc). In the majority of cases, the surgical treatment was replaced by the paracentetic treatment with local application of the combinations of oxytocin and antibiotics. This markedly decreased (by 3-4 times) the periods of temporary disability, provided better cosmetic results of the treatment and lowered consumption of the dressing material.
