[Quality assurance of rapid on-site evaluation of CT-guided fine-needle aspiration cytology of lung nodules].

Introduction: The methods available for the diagnosis of lung cancer include radiologic, cytologic and pathologic procedures.

Aims: The aim of this study was to determine the quality assurance of CT guided fine needle aspiration cytology of lung nodules.

Methods: Cytology results were rated to 4 categories (positive; suspicious; negative; not representative).

[Abdominal partial resection of the vagina and colpopexy: experiences with the procedure for posthysterectomy vault prolapse in 74 cases].

Objective: To assess the abdominal partial resection of the vagina and infundibulopelvic colpopexia in women with posthysterectomy vaginal vault prolapse. OPERATIVE PROCEDURE AND MATERIAL: Slightly modifying the method described by Lampé, after laparotomy the elongated vaginal wall is resected and the vaginal vault is fixed by the sutures placed into the infundibulopelvic, sacrouterine, and round ligaments. The area is covered and elevated by the overlapping peritoneum.

The role of gastric mucosal dysplasia in the development of gastric carcinoma.

It is widely acknowledged that most stomach carcinomas developed from dysplastic lesions of gastric mucosa. They can be found in known precancerous conditions as chronic gastritis, gastric adenoma, giant rugal hypertrophy, chronic peptic ulcer, gastric stump after partial resection and pernicious anemia. Several grading systems of gastric dysplasia have been suggested.

Investigation of effect of lesser curvature seromyotomy of the stomach in animal experiments.

The effectiveness of seromyotomy of the lesser curvature of the stomach--the simplified version of proximal selective vagotomy--was investigated in eleven dogs. Decreased acid secretion was proved with congo red test and pH measuring by glass electrode. No significant damage to the motor function of the stomach was found with scintigraphy.

[Correlation between neonatal mortality and hyperinsulinema].

The authors investigated the correlation among the severity of maternal diabetes, the tight control of the maternal blood glucose concentration and the neonatal morbidity. Umbilical cord insulin level were measured in 115 newborns, 40 of them have diabetic mother. There were significant different in the serum insulin level between the low and high morbidity group.

[Insulin concentration in amniotic fluid in mid-term pregnancy].

Insulin concentrations of 284 amniotic fluid samples were assessed, obtained from pregnant women by genetic amniocentesis between the 16-18 gestational weeks. The indication of amniocentesis was either advanced maternal age (> 35 years) or high risk genetic history. The amniotic fluid insulin concentration (mean +/- SD) was found 3.

Papova viruses and recurrent laryngeal papillomatosis.

The pathogenesis of larynx papillomas has been a challenge of medical science for a long time. Both clinical observations and electronmicroscopical examinations have made it possible to establish the viral origin. Final evidence, however, has been achieved only by complicated immunohistochemical investigations.

[The effect of lesser curve seromyotomy of the stomach in animal experiments].

The authors investigated the efficiency of the seromyotomy of the lesser curvature of the stomach in 11 dogs. Reduction of the acid production was verified by glass electrode pH measuring of the gastric mucosa. Scintigraphic examination showed that the operation did not damage the motor function (motility) of the stomach.

Investigation of premalignant lesions of larynx epithelium with histoautoradiography and HPV-assay.

The histological evaluation of precancerous alterations of larynx epithelium is, in transitional cases, very difficult. The differentiation of harmless metaplasia, hyperplasia and keratosis from abnormal proliferation depends on the pathologist's training and experience. Fine diagnostic lines separate the different grades of dysplastic epithelial alterations.

Synovial sarcoma of the hypopharynx in an 11-year-old boy: treatment by partial supraglottic laryngopharyngectomy.

Synovial sarcoma in an extra-articular location is a very rare tumor, particularly in relation to childhood tumors. We report our experiences with an 11-year-old boy who suffered from swallowing difficulties caused by a polypoid tumor of the hypopharynx. Biopsy demonstrated a fusocellular carcinoma, while the epithelial components showed cytokeratin and neuron-specific enolase positivity.

[Clinical pathology of gastric mucosal dysplasia].

The stomach cancer develops on dysplastic lesions of gastric mucosa. It can be found in every precancerous condition, as chronic gastritis, gastric adenoma, giant rugal hypertrophy, chronic peptic ulcer, gastric stump after partial resection, pernicious anaemia. So, this dysplastic change is not a specific lesion.
