ABSTRACT
Background: Postmenopausal bleeding (PMB)accounts for 5% of gynecology visit. All with unexpected uterine bleeding should be evaluated for endometrial carcinoma since this potentially lethal disease is the cause of bleeding in approximately 10 percent patients (range 1 to 25 percent, depending upon risk factors). The aim of the study was to evaluate endometrial causes of postmenopausal bleeding (PMB) with it's correlation with endometrial thickness (ET)and hysteroscopy findings and endometrial tissue histopathology.Methods: A total 50 consecutive cases of PMB fulfilling the inclusion and exclusion criteria and giving informed consent were selected. Each patient was subjected to transvaginal sonography (TVS) in which uterus, adnexa and endometrial thickness (ET) was assessed. Then hysteroscopy and/or dilation and curettage was scheduled at subsequent visit. Endometrial sample was sent for histopathological examination. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and diagnostic accuracy was calculated for ET by TVS and hysteroscopy findings, considering histopathological diagnosis as the gold standard.Results: Most common endometrial cause of PMB was atrophic endometrium (44%). The other causes were endometrial carcinoma (18%), endometrial hyperplasia (18%), endometrial polyp (12%), endometritis (4%), and leiomyoma (4%). The diagnostic accuracy of ET by TVS at a cut-off point of 5 mm was 94% with sensitivity 89.3%, specificity 100%, PPV 100% and NPV 88%. The diagnostic accuracy of hysteroscopy was 98% with sensitivity 96.4%, specificity 100%, PPV 100% and NPV 95.7%.Conclusions: Being relatively cheap, easily accessible, non-invasive, TVS with ET measurement should first line investigation in the evaluation of women with postmenopausal bleeding with suspected endometrial pathology. Although hysteroscopy is more specific and sensitive, in poor resource settings it should be limited to cases with ill-defined endometrial lining, recurrent/ persistent bleeding and cases with endometrial thickness greater than 5 mm irrespective of endometrial echotexture.
ABSTRACT
Background: Thrombocytopenia is second most common hematological abnormality in pregnancy after anemia (Incidence 8-10%). The aim of this study is to observe the obstetric and neonatal outcomes of pregnancies complicated with thrombocytopenia and to compare its maternal and fetal outcomes.Methods: The prospective observational study was conducted at tertiary care institute over period of one and half year and 100 cases of thrombocytopenia in present pregnancy were included after fulfilling inclusion and exclusion criteria and obtaining written informed valid consent. Complete history, physical examination and relevant investigations of the patient were documented. Patients were followed up to delivery and outcomes (obstetric, maternal, fetal, neonatal) were studied. The data obtained for all the patients was analyzed with SPSS (SPSS Inc, Chicago) software packages. Statistical comparisons were performed with Pearson’s Chi- square where appropriate with p-value of <0.05 considered statistically significant.Results: Most common cause of thrombocytopenia in pregnancy was gestational thrombocytopenia in (25%) cases followed by preeclampsia (20%). Most cases (94%) were diagnosed in antepartum period out of which most (58%) at >37 weeks of gestation. Most (53%) had moderate thrombocytopenia. Incidence of maternal complications was statically significant (P-value 0.038) with most common complication being caesarian section site oozing (9%) followed by placental abruption (4%). There was no statistical significance in degree of thrombocytopenia and need for blood and blood product transfusion (P-value 0.67). Only (2%) neonates of thrombocytopenic mothers had thrombocytopenia and both required treatment.Conclusions: Most common cause of thrombocytopenia in pregnancy was gestational thrombocytopenia with uneventful pregnancy and perinatal outcomes. Few severe cases associated with medical or systematic causes leads to serious catastrophic events which can be avoided by increasing antenatal surveillance and appropriate management by multidisciplinary team of obstetrician, hematologist, anesthesiologist, neonatologist and physician.
ABSTRACT
Purpose of the study: Demonstration of nerve-muscle experiments play a vital role for teaching Physiologyto undergraduate medical students. In recent days, procuring frogs for the conduction of these experimentshave become a major concern. Therefore, we have designed an innovative method to carry out nerve-musclePhysiology experiments in human subjects.Methodology: We designed a simple and feasible method to demonstrate the effect of increasing strengthof stimuli, two successive stimuli and tetanic stimuli on human finger muscle twitch response.Main findings: Results of four nerve-muscle experiments performed in a human subject using an innovativemethod has been presented in this article. First, recording of finger muscle twitch by ulnar nerve stimulation.Second, effect of subthreshold, threshold, maximal and supramaximal stimulus with increase in the strengthof stimulus. Third, effect of two successive stimuli on finger twitch response. Four, effect of tetanizingstimuli on finger twitch response.Conclusion: Here we propose a simple innovative practical for effective demonstration of nerve-musclePhysiology experiments using human subject for under-graduate teaching.
ABSTRACT
13 essential hypertensive patients aged 41 to 60 years were given yoga training for 60 min daily, Monday through Saturday, for a total duration of 4 weeks. Blood pressure and heart rate (HR) were measured with non-invasive semi-automatic blood pressure monitor. Measurements were recorded before the training and at weekly intervals during the 4 week training period. Results of our study show a significant (P<0.001) reduction in resting HR and rate-pressure-product (RPP) after 2 weeks of yoga training. Systolic pressure (SP), diastolic pressure (DP) (P<0.001) and mean pressure (MP) (P<0.05) showed a significant reduction at 3 weeks of training period. After 4 weeks of training, there was further fall in SP, DP, pulse pressure (PP) (P<0.05), MP (P<0.001), HR and RPP. Isometric handgrip test before yoga training produced a significant rise in SP and MP and insignificant rise in DP, HR and RPP. After yoga training, there was a significant rise in all these parameters. Our results show that yoga training optimises the sympathetic response to stressful stimuli like isometric handgrip test and restores the autonomic regulatory reflex mechanisms in hypertensive patients.
