Social-hygienic study of the epidemiology of primary and secondary female infertility

Incidence of primary and secondary female infertility is analyzed from results of 10-year follow-up of 3478 couples married in Ryazan, a city in Central Russia. Data of sociohygienic studies of epidemiology of sterility should be taken into consideration when planning measures aimed at prevention of reproductive disorders in various sociodemographic strata of population.     

Diagnostic laparoscopy in hematologic patients

The authors analyze indications, technique and results of 143 laparoscopies in blood diseases and diseases with hematological symptoms; evidence obtained at combined and separate hepatic and splenic biopsies (55, 84 and 1 patients, respectively). Trepan biopsy was preferred to other biopsies. The technique proposed by the authors is complications safe even in patients with serious hemostatic disorders.     

Diagnostic value of hysterosalpingography and laparoscopy in infertile women

Tubal pathology with tubal blockage due to the pelvic inflammatory diseases is one of the most frequent causes of infertility in a woman [1]. The two most important diagnostic procedures which are used for evaluation of tubal patency are hysterosalpingography and laparoscopic hydrotubation [4]. SUBJECT: The aim of the study was the comparison of hysterosalpingographic and laparoscopic findings and determination of accuracy of these two procedures in the diagnosis of tubal patency. MATERIAL AND METHODS: We studied and compared the results of hysterosalpingography and laparoscopy in 102 infertile women who were operated on at the Narodni Front Hospital of Gynaecology and Obstetrics in Belgrade during 1993 and 1994. Of 102 operated women 47 women were with primary infertility and 55 with secondary infertility. The patients were from 20 to 41 years of age, the average 28 +/- 2.4 years. RESULTS: Of one hundred and two operated women tubal blockage was found in 94 (92.1%) patients. Unilateral hydrosalpinx was found by hysterosalpingography in 16 (15.7%) subjects and bilateral hydrosalpinx in 30 (29.4%) women. Unilateral hydrosalpinx was found by laparoscopy in 17 (16.1%) patients and bilateral hydrosalpinx in 32 (31.4%) subjects. The concordant findings by hysterosalpingography and laparoscopy in the diagnostics of unilateral hydrosalpinx were found in 76.5% of cases, and in bilateral hydrosalpinx in 70.4%. This difference was not statistically significant. Unilateral tubal blockage was identified by laparoscopy in 26 (25.5%) patients and bilateral in 27 (26.5%) subjects. The concordant findings by hysterosalpingography and laparoscopy in unilateral tubal blockage were found in 61.5% of cases, and in bilateral tubal blockage in 70.4% of women. The total concordant findings by hysterosalpingography and laparoscopy in tubal blockage were found in 65.7 of cases, and concordant findings after hysterosalpingography and surgery were noted in 61.7% cases. The findings by laparoscopy and surgery were in harmony in 86.3% patients. Ovarian abnormalities were found by laparoscopy and surgery in 22 (21.6%) women. Pelvic adhesions were found by laparoscopy in 42 women of 49 patients in whom pelvic adhesions were found during the operation. Uterine congenital anomalies were found by laparoscopy in 3 (2.9%), women and by hysterosalpingography in 6 (5.9%) patients. DISCUSSION: Of 102 operated women tubal blockage was found in 94 (92.2%) women. Unilateral tubal blockage was found in 38 (40.4%) patients, and bilateral tubal blockage in 56 (59.6%) subjects. Hysterosalpingographic and laparoscopic hydrotubation findings in the diagnosis of tubal patency were concordant in 65% of cases, hysterosalpingographic and operative findings in 61.7% of patients, and laparoscopic and operative findings in 86.3% of subjects. Although concordant findings of 65.7% were noted in this study, which were similar to findings of other authors, the percentage of 62.5% [4], and 76% was observed [5]. During the operation pelvic adhesions were found in 49 patients, and laparoscopic in 42 women only. Ovarian abnormalities were found by laparoscopy in 22 (21.6%) patients, while uterine fibroid was found in 10 (9.8%) subjects. Uterine congenital anomalies were found by hysterosalpingography in 6 (5.9%) cases and by laparoscopy only in 3 (2.9%) patients. The advantage of visual hysterosalpingography seems to be in identification of some congenital uterine anomalies. However, the advantage of laparoscopy is identified by the possibility of visualisation of some other pelvic abnormalities which may be the cause of infertility. CONCLUSION: There are some hysterosalpingographic and laparoscopic advantages and disadvantages in the diagnosis of infertility in women. Only by using both procedures accurate results can be achieved in the tubes, the uterus and the ovary, that can be a cause of infertility in women.     

Myomectomy by laparoscopy and infertility: status of the controversy

The authors report a case of fibroplastic endocarditis discovered during echocardiography in an asymptomatic patient in the context of assessment of systematized electrocardiographic modifications. The diagnosis, strongly suspected on the basis of the cardiac MRI findings, was finally confirmed by endocardial biopsy.     

Diagnostic and therapeutic laparoscopy of the nonpalpable testis

We report about laparoscopic examination and treatment of 19 patients with 25 non-palpable testes. Thirteen patients presented with unilateral and six patients with bilateral absent testes, respectively. In all cases of non-palpable testes laparoscopy was able to determine the exact localization and supported the surgical approach. Six testicles were treated by open orchiectomy after diagnostic laparoscopy; three testes were fixed by laparoscopically assisted orchiopexy. Three patients (three testicles) were treated by standard orchiopexy after laparoscopy and in three cases microvascular autotransplantation was performed. Laparoscopically, five aplastic testicles without vas and vessels were diagnosed. Three testes were considered as vanishing and in two patients (two testes) due to previous surgical exploration elsewhere testicular remnants were totally atrophic and were resected with the adjacent vas. All laparoscopic findings except the vanishing testis syndrome were proven either by open surgery or by laparoscopic preparation of the internal inguinal ring.     

Diagnostic laparoscopy in 1043 patients with suspected acute appendicitis

OBJECTIVE: To evaluate the efficacy of diagnostic laparoscopy in patients with suspected acute appendicitis, the number of complications associated with the laparoscopic technique, and the effect of leaving a macroscopically normal-looking appendix in place. DESIGN: Three prospective protocols. SETTING: Three departments of surgery, one in Norway and two in Sweden. SUBJECTS: 1043 patients aged 15 years or over. INTERVENTIONS: Diagnostic laparoscopy in patients with signs and symptoms of acute appendicitis who were to be operated on. MAIN OUTCOME MEASURES: Morbidity, mortality, and histological appearance of removed appendices, and outcome whether or not the patient was operated on. RESULTS: 819 patients had appendectomies (61% laparoscopically and 39% by conversion to open operation) with a total complication rate of 10%. In 211 patients a diagnostic laparoscopy was done as a single procedure. There were 181 women in this group and 86 of them had gynaecological disorders. The complication rate was 2% among these 211 patients and after a follow up of two years no patients had been readmitted for appendicectomy. 13 patients were subjected to other open procedures. The overall mortality was 0.4%. CONCLUSION: Diagnostic laparoscopy is safe and can be recommended in patients with suspected acute appendicitis, particularly in women. A macroscopically normal-looking appendix can be left in place.     

Diagnostic implications of the B-mitten EEG pattern: relationship to primary and secondary affective dysregulation

Previous studies indicate that the B-Mitten EEG pattern is specific to psychiatric dysfunction and rarely encountered among normal control subjects. Our previous investigations have demonstrated a significant relationship between mittens and reactive as opposed to process schizophrenic disease. Re-analyses of mitten incidence in schizophrenics and nonschizophrenics suggests needed modification of our earlier B-Mitten-schizophrenia formulation. Present considerations indicate that the B-Mitten-reactive schizophrenia association is not primary but rather that the differential process-reactive schizophrenia mitten incidence may be a secondary epiphenomenon reflecting a more fundamental underlying process. Analyses are presented suggesting that the mitten dysrhythmia relates positively to dysphoric affective dysregulation in a manner which cuts across broad diagnostic boundaries. That the mitten pattern possibly suggests as yet unclarified subcortical dysfunction associated with symptoms of affective disturbance is a tentative hypothesis offered for consideration.     

Diagnostic laparoscopy and liver disease: experience of 200 cases

BACKGROUND: Laparoscopy is an old technique that is frequently used by gastroenterologists in America and Germany. With modern equipment it is now possible to perform this technique under local anaesthesia. AIM: To evaluate the usefulness and safety of laparoscopic liver biopsy. METHODS: Liver biopsy was routinely performed by laparoscopy under local anaesthetic and sedation. A standard 5 mm laparoscope was used and a pneumoperitoneum induced with nitrous oxide. RESULTS: Two hundred consecutive patients were laparoscoped and underwent liver biopsy. In five patients the liver could not be visualised due to adhesions. Two patients had bleeds related to the procedure. Twenty-five patients had malignancy diagnosed by guided biopsy. Eight of these had been missed by ultrasound prior to laparoscopy. Cirrhosis was diagnosed laparoscopically in 72 patients. Histology was unable to confirm this diagnosis in four patients. CONCLUSION: Laparoscopy can be performed safely and comfortably on patients with local anaesthetic and sedation. The visualisation of the liver can add valuable information to liver biopsy.     

Diagnostic laparoscopy in patients with an acute abdomen of uncertain etiology

The occurrence of multiple mating in Drosophila melanogaster is of particular interest to evolutionary biologists, as seminal fluid has some toxic effects for females. Thus, it has been predicted that the number of matings per females should be low. We have tested this prediction with seven highly polymorphic microsatellite loci in inseminated females from a Viennese D. melanogaster population. In contrast to the predicted low number of matings and previous studies in natural populations, we identified the genotypes of four to six different males fertilizing the offspring of each female tested. Potential causes and consequences are discussed.     

Genetic alterations in primary and secondary hyperparathyroidism

OBJECTIVE: To evaluate treatment of patients with primary liver cancer. DESIGN: Prospective protocol including subsets of randomised studies. SETTING: University hospital, Sweden. SUBJECTS: 123 patients with primary liver cancer. INTERVENTIONS: 64 patients underwent hepatic resection, 25 were included in a trial of adjuvant chemotherapy. 24 further patients whose tumours were not resectable were included in a trial of intra-arterial infusion of doxorubicin. MAIN OUTCOME MEASURES: Survival and postoperative morbidity. RESULTS: The median survival time for patients who had had resections was 11 months (range 0-111). Twelve per cent survived more than 5 years. No prognostic factor had any significant effect on outcome. The postoperative mortality was 11% (7/64). The patients allocated to adjuvant chemotherapy survived a median of 10 months (range 1-47) and the controls 29 months (range 8-111) (p=0.04). Patients with unresectable liver cancer treated with intra-arterial doxorubicin lived no longer than untreated controls (median 8 months (range 1-56) compared with 7 months (range 1-28)). CONCLUSIONS: Treatment of patients with primary liver cancer is still an unsolved problem. Adjuvant chemotherapy with doxorubicin had no beneficial effect on survival.     

Diagnostic laparoscopy through the right lower abdominal incision following open appendectomy

BACKGROUND: Diagnostic laparoscopy through the right lower abdominal incision following open appendectomy for suspected acute appendicitis may help in making the correct diagnosis in the absence of pathology of the appendix. METHODS: Fourteen patients with a clinical diagnosis of acute appendicitis underwent diagnostic laparoscopy through the right lower quadrant incision after open appendectomy to exclude further pathology in the case of a noninflamed appendix. RESULTS: In 10 of the 14 patients, laparoscopy helped to correct the diagnosis. In two patients, the etiology of the acute right lower abdominal pain remained unclear. In two others, histological examination showed acute appendicitis despite a normal macroscopic appearance. CONCLUSIONS: Diagnostic laparoscopy through the right lower quadrant incision may help to correct the diagnosis in patients who are operated on for clinically acute appendicitis but in whom no acute appendicitis or other pathological findings are seen.     

Sensorimotor integration in human primary and secondary somatosensory cortices

We measured somatosensory evoked fields (SEFs) to electric median nerve stimuli from eight healthy subjects with a whole-scalp 122-channel neuromagnetometer in two different conditions: (i) 'rest', with stimuli producing clear tactile sensation without any motor movement, and (ii) 'contraction' with exactly the same stimuli as in 'rest', but with the subjects maintaining sub-maximal isometric contraction in thenar muscles of the stimulated hand. The aim was to study the role of the primary (SI) and secondary somatosensory (SII) cortices in sensorimotor integration. The amplitude of the SI response N20m did not change with coincident isometric contraction, whereas P35m was significantly reduced. On the contrary, activation of contra- and ipsilateral SII cortices was significantly enhanced during the contraction. We suggest that isometric contraction facilitates activation of SII cortices to tactile stimuli, possibly by decreasing inhibition from the SI cortex. The enhanced SII activation may be related to tuning of SII neurons towards relevant tactile input arising from the region of the body where the muscle activation occurs.     

Carboxyhemoglobin levels in primary and secondary cigar and pipe smokers

This study of 130 subjects was performed to obtain more data about the smoking habits and levels of carboxyhemoglobin in various types of pipe and cigar smokers. These smokers may be divided by history into primary or secondary smokers and also into current inhalers and noninhalers. Prior studies of carboxyhemoglobin levels have yielded conflicting results, presumably due to differences in current habits of inhalation, which were often not taken into account. Cigarette, primary pipe, and secondary pipe inhalers had similar carboxyhemoglobin levels that were significantly higher than nonsmokers (5.6, 5.0, 5.4, and 1.0 percent, respectively). Cigar inhalers had markedly elevated concentrations of carboxyhemoglobin (13.8 and 11.8 percent in primary and secondary inhalers, respectively). Most secondary cigar and pipe smokers inhaled, whereas most primary smokers did not. Intentional inhalation, rather than past smoking history, is the most important factor in determining the carboxyhemoglobin level for each type of smoke.     

Diagnostic and therapeutic update on primary duodenogastric reflux

The authors, after some remarks on the pathophysiology of primary alkaline gastritis, analyze the main methods, available at present, for diagnosis; they particularly consider the importance of endoscopy and histology, gastroesophageal 24-hours pH-metry and 99mTc HIDA scintigraphy. Successively, they present the criteria for the identification of patients who will predictably benefit from surgical treatment, and examine advantages and limits of the two main corrective surgical techniques for the duodenogastric reflux in patients not previously operated on the gastrointestinal tract: duodenal extramucosal myotomy according to Mattioli, relatively easy to perform, and the "duodenal switch" according to De Meester, technically more complex, but pathophysiologically more acceptable, completely eliminating the duodenogastric reflux.     

Clinical features of primary and secondary atypical mycobacteriosis

A clinical investigation was carried out in 39 patients with atypical mycobacteriosis (AM). The patients at our hospital diagnosed as having AM during an 11-year period from 1981 to 1991 were reviewed in this study. The incidence of AM among all of mycobacterial infections has been increasing since 1988. The atypical mycobacteria detected included M. avium complex (MAC) in 79%, M. kansasii in 26%, and other organisms in 5%. Patients who had primary infection without underlying respiratory disease were compared with those who had secondary infection. In secondary infection, MAC was detected in the sputum of a high percentage of patients and was positive for more than 6 months despite therapy. Gamma globulin levels were also increased in patients with secondary infection. Cell mediated immunity was examined by the DNCB reaction and the detection of CD4- and CD8- positive T lymphocytes. The DNCB skin reaction was positive in 6 out of 26 patients with secondary infection. The percentage of CD8- positive T lymphocytes was higher in patients with secondary disease. Fischer's ratio (indicating the balance of plasma amino acids) was also examined as an index of the nutritional status. It was significantly lower in secondary infection compared with primary infection. Moreover, secondary infection was associated with a lower positive rate for the DNCB skin reaction and a lower Fischer's ratio when compared with pulmonary tuberculosis. Thus impairment of cell-mediated immunity, malnutrition, and a poor prognosis were significantly more common in secondary infection compared with primary infection.     

Therapeutic approaches to primary and secondary brain tumours

INTRODUCTION: This study examined the long-term effects of hysterectomy, with and without bilateral oophorectomy, and treatment with estrogen replacement on bone mineral density in older hysterectomized women. METHODS: Subjects were 346 women 60-89 years of age, who were participants in the Rancho Bernardo Study and attended a follow-up clinic visit in 1988-1991. Bone density was measured at the ultradistal wrist, midshaft radius, lumbar spine and hip. RESULTS: Of these women, 182 had a hysterectomy with conservation of one or both ovaries and 164 had a hysterectomy with bilateral oophorectomy. Current estrogen users had the highest bone densities; those who never used estrogen replacement had the lowest. Only 9.1% of oophorectomized women, compared to 19.2% of those with ovarian conservation had never used estrogen (P < .01). After adjustment for covariates including estrogen replacement therapy, hysterectomized women with ovarian conservation had marginally higher bone densities at the wrist (P < .09) and spine (P < .06) than oophorectomized women. We found significant differences only among women currently using estrogen (P < .05 for wrist and P < .01 for spine densities, respectively). Bone density did not differ at any site by oophorectomy status among past or never users of estrogen. CONCLUSIONS: Hysterectomized women who use estrogen replacement therapy have better bone density, regardless of a bilateral oophorectomy. In addition, bilateral oophorectomy may not have a long-term negative effect on bone density; hysterectomized women who do not use estrogen appear to have equivalent bone density whether or not they had a bilateral oophorectomy.     

Optimal management of primary and secondary mitral regurgitation

Systemic lupus erythematosus and antiphospholipid antibody syndrome are associated with an increased risk of intrauterine growth restriction, miscarriage, stillbirth and premature delivery. Recent advances in therapy during pregnancy have improved the outcome but there is still significant fetal and maternal morbidity and mortality. Treatment of patients failing conventional therapy during the second half of pregnancy is difficult and may be complicated by the development of preeclampsia. The addition of intravenous immunoglobulin therapy offers a low risk strategy for reducing autoantibody mediated disease and improving placental function in severely compromised, growth restricted pregnancies.
