[Endometrial ablation and resection techniques].

OBJECTIVE: To summarize all currently used and experimental, hysteroscopic and non-hysteroscopic methods of endometrial ablation and resection, their indications, operation techniques, and treatment results. DESIGN: Literary review. SETTING: Department of Obstetrics and Gynecology, Medical Faculty and Faculty Hospital, Charles university, Capkovo námĕstí 1, Plzen, Czech Republic. METHODS: Analysis of the literature (textbooks, medical journals, database Medline, Current Contents, Embase, PubMed). RESULTS AND CONCLUSION: Endometrial ablation and resection play an important role in the treatment of dysfunctional uterine bleeding. Hysteroscopic methods visualize the uterine cavity and enable to treat lesions in it at the same time. Non-hysteroscopic methods are less invasive for the patient and comfortable for the surgeon. Both groups of methods have similar treatment results.

[Malignant gynecologic neoplasms in the Czech Republic 1986-1995].

OBJECTIVE: The incidence and mortality of malignant tumours of the uterine cervix, uterine body and ovary are analysed. DESIGN: Retrospective study. SETTING: Department of Obstetrics and Gynecology, Medical Faculty and Faculty Hospital, Charles University, Plzen. METHODS: Analysis of relevant dates from the National Oncological Registry 1986-1995. RESULTS: The incidence of the cervical carcinoma oscilated around 22 (22.7-21.6), the mortality slightly decreased (9.6-8.4). The incidence of the corpus carcinoma rose again (25.9-28.9), its mortality declined (7.4-6.9). The incidence of malignant ovarian tumours significantly increased (16.3-23.4), the mortality became slightly higher (14.8-16.2). The incidence of the ovarian carcinoma got ahead the incidence of the cervical carcinoma (23.4:21.6) and it occupied the second place after the corpus carcinoma. CONCLUSIONS: It is necessary to screen systematically gynecological malignant tumours and concentrate its treatment to specialized centers. Correct reports of these tumours and their precise staging is needed, too.

[Hysteroscopic polypectomy versus fractionated curettage in the treatment of corporal polyps--recurrence of corporal polyps].

OBJECTIVE: The evaluation of hysteroscopy contribution in the treatment of endometrial polyp. The evaluation of the risk of endometrial polyp recurrence. DESIGN: Prospective clinical study. SETTING: Department of Obstetrics and Gynecology of Medical faculty and Faculty Hospital, Pilsen. METHODS: Two groups of patients were followed. Group I had 81 patients (30 premenopausal and 51 postmenopausal) that underwent hysteroscopical polypectomy followed by diagnostic hysteroscopy in 6-12 months. Group II consisted of 100 patients (36 premenopausal and 64 postmenopausal) that underwent fractional curretage with histological diagnosis of endometrial polyp. These patients were checked by diagnostic hysteroscopy in up to 12 months. Presence of endometrial polyp during diagnostic hysteroscopy and a relation of its recurrence or persistence to a type of preceding procedure, risk factors and histological findings during the first procedure were evaluated. RESULTS: 11 (13.5%) cases of an endometrial polyp were recorded in hysteroscopical controls in group I. 46 (46%) cases of an endometrial polyp were recorded in group II. Recurrence of the endometrial polyp was revealed only in one case of atrophic endometrium and in no case of atrophic endometrial polyp. CONCLUSION: Hysteroscopical polypectomy showed considerably better results in the treatment of endometrial polyp comparing to fractional curretage. The recurrence risk of endometrial polyp is expected in a case of presence of an abnormal proliferative activity or hyperplasia both in the endometrial polyp and the surrounding endometrium.

Blood acid-base and serum electrolyte values in red deer (Cervus elaphus).

Acid-base, serum electrolyte, plasma protein, and packed cell volume (PCV) values were determined in venous blood samples from 30 red deer (Cervus elaphus) of both sexes showing no clinical signs of disease. The animals were 5 months of age and kept on pasture in the Valley of Mexico, at an altitude of 2450 m. Blood samples were collected without sedation. Mean blood values were: pH 7.411 +/- 0.041, pCO2 37.7 +/- 4.4 mmHg, base excess 0.7 +/- 3.2 mmol/L, actual bicarbonate 24.3 +/- 3.1 mmol/L, total CO2 25.3 +/- 3.2 mmol/L and anion gap 23.5 +/- 5.5 mmol/L. Mean serum electrolyte levels were: Na+ 142.3 +/- 2.5 mmol/L, Cl- 100.5 +/- 2.3 mmol/L, and K+ 7.03 +/- 1.03 mmol/L. Plasma protein and PCV values were 60.0 +/- 6.6 g/L and 0.47 +/- 0.05 L/L, respectively. Blood values determined in this study can be considered reference data for health control and disease diagnosis.

An unusual case of malignant Brenner tumor in association with low-grade urothelial carcinoma of the urinary bladder. A case report.

We present a case of a 45-year-old Caucasian female with a malignant Brenner tumor arising at the site of the right ovary 21 years after right adnexectomy performed for ectopic pregnancy. Several months after the presentation of the malignant Brenner tumor the patient was diagnosed with low-grade urothelial carcinoma of the urinary bladder. All clinical, biochemical, and pathological findings with the emphasis on the differential diagnosis are summarized. A brief survey of histological theories and classification of Brenner tumors as well as therapeutic approaches with their results are given. We have found a few papers [1, 2] dealing with the coexistence of Brenner tumors with urothelial ones, but to our knowledge the coexistence of both malignant tumors has not been published previously.

[Cervical glassy-cell carcinoma--case report].

OBJECTIVE: A rare case of a mixed cervical carcinoma is described. SUBJECT: Glassy-cell carcinoma of the uterine cervix in association with a bilateral benign superficial serous papilloma of the ovary in a 44-year-old woman. CONCLUSION: The possible occurrence of aggressive tumours of the uterine cervix with emphasis on their adequate treatment is pointed out. At the same time the importance of a peroperative biopsy of suspect macroscopic findings on the ovaries is stressed. The paper reports on a previously unpublished case of simultaneous occurrence of the above mentioned tumours.

[Zona pellucida antibody detection using the passive hemagglutination reaction. II. Clinical part].

The authors examined sera of patients suffering from idiopathic infertility, unsuccessful IVF, the diagnosis of habitual abortion and endometriosis, using the test of the passive haemagglutination reaction with sheep erythrocytes sensitized by 11 antigenic fractions of pig zona pellucida, molecular weights from 13.3-114 kilodaltons. The authors analyze the assembled results with regard to individual antigenic fractions and with regard to the diagnoses. The frequency of positive reactions in patients is investigated in particular in the area of higher molecular weights, as compared with the control group of healthy fertile women.

[Labor induction in cows and its effect on the development of biochemical and hematologic indicators in the blood of calves].

The effect of induction of parturitions in the 1-2 weeks of pregnancy was tested as exerted on the health of calves and on some biochemical and hematological indicators. The observations concerned 26 cows, out of which 14 cows (experimental group) were applied intramuscularly 500 micrograms of synthetic analog of prostaglandin F2 of alpha- cloprostenol. The other 12 cows were a control group. These indicators were determined in the blood of calves before colostrum intake, in 24 h, 5 and 15 days from the intake of the first colostrum ration: acid-base balance, hematocrit and leucocyte counts, in the blood plasma it was concentrations of glucose, urea, Na, K, Ca, inorganic P, vitamin A and E levels and AST and GMT activities. The same range of examinations was performed in the blood and/or in the blood plasma of cows, in addition to urea screening. Blood and urea samples were taken a month before and a month after parturition. No deviations from the normal state were found by the examination of highly-pregnant cows. Afterbirth retention was found in 87% cows of the experimental group after parturition, while it was only 9.8% in the control group. All the calves in the experiment had good vitality, very good health in the course of 15-day observation. There were not any significant differences in the birth weight and weight gains of the calves of experimental and control groups.(ABSTRACT TRUNCATED AT 250 WORDS)

[Malignant ovarian neoplasms--a constant challenge to gynecologists].

The annual incidence of malignant neoplasms of the ovary has increased in the Czech Republic between 1961 and 1988 from 14.3 to 17.2 newly notified cases per 100,000 women. The highest incidence, 47.03, is in the age group from 70 to 74 years. It participates in the overall mortality from malignant tumours of the genitalia by 41.6%, although in the total incidence it accounts for 25%. The lethality calculated from the incidence and mortality in the Czech Republic in similar as in other countries--79%. This is consistent with the generally reported survival period after treatment which is 20-30%. Hospital statistics report more favourable results. Introduction of new therapeutic methods so far did not lead to marked improvement of therapeutic results. The latter are influenced more by detection of the disease in early stages.

[Esophageal injuries].

The authors present an analysis of 33 oesophageal injuries treated at the surgical clinic of Faculty Hospital Plzen in 1976-1991. Iatrogenic injuries predominated (a total of 24 cases). Of these seven developed during oesophagoscopy performed on account of dysphagic complaints caused by benign or malignant disease. Ten injuries developed in conjunction with endoscopic extraction of a foreign body, three occurred during operation of hiatus hernia, two during sclerotization of oesophageal varices and one each during insertion of a nasogastric tube and oesophageal endoprosthesis. In the remaining cases perforation occurred during traumatic injury of the neck four times, twice as a result of a swallowed bone, and three perforations were spontaneous. The total mortality was 27.3%. The authors analyze factors which influence the morbidity and mortality--the site of injury, the time which elapsed between injury and treatment, the patient's age, mode of injury, associated diseases and method of treatment. They found that the most frequent complication and most frequent cause of death was septicaemia from mediastinitis and empyema of the chest.

[Epidemiology of malignant tumors of the uterus].

The authors describe the frequency, incidence, number of deaths and mortality from malignant tumours of the uterine corpus in the Czech Republic in 1961-1988. The mean incidence of 13.06 during the five-year period 1961-1965 rose to a mean incidence of 25.12 during the five-year period 1984-1988, while during this period a paradoxical decline of the mortality from 9.00 to 6.7 occurred. This implies a decline of the lethality during 1961-1965 from 76.56% to 28.98%, i.e. to 37.85% of the original value. The reasons of the decline in lethality may be earlier detection of the disease and possibly a rise in the incidence of less aggressive forms of hormone-dependent carcinomas only, because therapy did not change essentially during the mentioned period.
