An analysis of the efficacy of uterine artery embolization in obstetrical hemorrhage
Background: Obstetrical hemorrhage is the single most important cause of maternal morbidity and mortality. The study is conducted at a tertiary-care hospital to assess the efficacy of uterine artery embolization as a treatment for obstetrical uterine hemorrhage. It examines various aspects such as the outcome of the procedure, need of blood and blood products, need of secondary procedures post intervention and the possibility of future pregnancies.
Methods: It was a retrospective observational study conducted with sample size of 20 patients with obstetrical hemorrhage at the Department of Obstetrics and Gynecology of Bhagwan Mahaveer Jain Hospital, Bengaluru in India between January 2011 to July 2019.
Results: Records of 20 patients with obstetrical hemorrhage were assessed. The study indicates that 11 patients experienced postpartum hemorrhage (PPH), 5 postabortal bleeding & 4 bleeding due to scar ectopic. Out of 20 patients, hemodynamic stability was achieved in 17 cases (85%), hysterectomy was needed in 2 cases (10%) and 1 (5%) patient died after the procedure. Of total 20 cases, 18 (90%) required secondary procedures post-intervention like dilatation and evacuation 6 cases (33.3% of total cases), vaginal suturing and packing 10 cases (55.5% of total cases) and supportive measures like PPH and Disseminated intravascular coagulation (DIC) management in 2 cases (11.1% of total cases). Blood transfusion was given in 15 cases (75%) after the procedure. Future pregnancy was attained in 8 cases (47%) after considering the history of the patients, loss of follow-up, possibility of complications, family planning and hysterectomy performed.
Conclusions: Uterine artery embolization is a very effective method to control obstetric hemorrhage with high success and low complication rate and hysterectomy can be avoided to preserve fertility
A Novel Method for Classification of Wrist Pulse for Health Monitoring using Sparse Classifier
A wrist pulse system has been developed that can detect both normal and abnormal conditions in patients based on wrist pulse diagnosis. Pulse diagnosis are mainly done in three steps they are pulse preprocessing, feature extraction and classification. The acquired wrist pulse signal is passed through consecutive stages of denoising, baseline wander removal and period segmentation. The feature extraction is then done to extract time domain, frequency domain and wavelet features. Classification is then done for finding normal and abnormal conditions using SVM (Support Vector Machine) classifier. It is found that by using the SVM classifier, distributed features cannot be efficiently identified, classification accuracy is low and sub-classification cannot be done for abnormal condition as SVM supports only binary data. So SVM classifier is replaced by sparse classifier which has higher accuracy since it supports highly nonlinear data. T test is used in feature selection so that it needs low memory and less time consumption. Sub-classification has been done for the abnormal cases of Anemia, Arrhythmia, Tuberculosis and Wolff Parkinson White Syndrome
Uterine arteriovenous malformation-beyond surgery: a case series
Uterine arteriovenous malformations (AVM) are a rare entity, presenting in women of reproductive age. The presentation may vary with bleeding being the chief presenting symptom. Though traditionally hysterectomy has been a definitive form of treatment, trans-catheter embolization is being considered as a good treatment option. We present three cases with uterine AVM who presented with heavy bleeding per vaginam. Three patients of reproductive age group (29-33 years) presented with heavy bleeding per vaginam from January 2017- May 2017. Two had previous miscarriages for which curettage was done and one had undergone a Caesarean section previously. Diagnosis of uterine AVM was made by ultrasound-grey scale, colour Doppler, followed by MRI. All patients underwent trans-catheter angiogram followed by selective embolization of the AVM with n-BCA (n- Butyl Cyanoacrylate) and polyvinyl alcohol (PVA) particles. Successful embolization was done in all of our patients with technical success rate of 100%. On follow-up, all patients are currently asymptomatic. Trans-catheter arterial embolization of uterine AVM is a simple and effective treatment alternative with less morbidity associated with anaesthesia and surgery in turn reducing hospital stay. It has to be considered in patients who need to preserve their fertility
Effects of Elsholtzia splendens and Cirsium japonicum on premenstrual syndrome
Premenstrual syndrome is a common chronic disorder in most women of reproductive age. The main symptoms are depression, anxiety, tension, feeling out of control, and mastalgia. In premenstrual syndrome, the effects of aromatic edible Elsholtzia splendens and Cirsium japonicum were investigated for over 3 months in 30 women participants in their twenties. In the Elsholtzia splendens capsule treated group, scores of depression and anxiety were significantly lower than those in the Cirsium japonicum capsule treated group. Moreover, instability of the premenstrual assessment form was significantly decreased in the Elsholtzia splendens capsule treated group. Our results suggest that Elsholtzia splendens could be an effective plant material in relieving symptoms of premenstrual syndrome
Ursodeoxycholic acid versus placebo in women with intrahepatic cholestasis of pregnancy (PITCHES): a randomised controlled trial
New temperature fluctuation method for direct determination of thermal activation energy of deep levels in semiconductors
A new method is suggested where the thermal activation energy is measured directly and not as a slope of an Arrhenius plot. The sample temperature T is allowed to fluctuate about a temperature T0. The reverse-biased sample diode is repeatedly pulsed towards zero bias and the transient capacitance C1 at time t1 is measured The activation energy is obtained by monitoring the fluctuations in C1 and T. The method has been used to measure the activation energy of the gold acceptor level in silicon
The photoionisation energy of the thermally induced +0.42 eV level in p-silicon
The photoionisation energies of thermally induced levels (H1 and H2) in a quenched n + p silicon diode are measured by the DLOS technique. The photoionisation cross sections are well described by the Lucovsky model. The measured photoionisation energies ( +0.42 eV and +0.52 eV) confirm the thermal activation energy determined by the DLTS method
Distribution of certain cations and anions in seaweeds and seawater of Saurashtra coast and their geochemical significance
37-42Na and Mg dominate over K and Ca respectively in seawater, but a reverse trend is observed in many seaweeds. This preferential accumulation of one element over another similar element is adjudged on the basis of differential percentage enrichment factor (DPEF). It is positive for K over Na (3986) and Ca over Mg (359). It reflects lower residence time () values of K and Ca which are preferentially accumulated than Na and Mg possessing higher (). Cl and I are more in brown seaweeds than in red and green seaweeds. Br is generally high in red seaweeds followed by brown and green seaweeds. The halogen content of investigated seaweeds is in the order Cl is greater than Br is greater than I is greater than F, whereas in seawater the trend is CI > Br > F > I [F values, Indian J Mar. Sci., 13 (1984) 47]. Their concentration factors, CF (median values), in seaweeds are in the order I > F > Br > CI. DPEF of I, F, Br and CI in seaweeds in relation to their other halogens of higher ralso show descending order:I over CI > I over Br > I over F > F over CI > Br over CI > F over CI. The trend of concentration of halogens in seaweeds compared to ambient medium (median values) suggests their relative uptake rates pattern. BnF ratio in seaweeds indicates that the accumulation of one halide is independent of the other. In general, shorter the (), more is die CF of cationic and anionic elements in seaweeds
Electrical properties of nickel-related deep levels in silicon
Electrically active deep levels related to nickel in silicon are studied under different diffusion conditions, quenching modes, and annealing conditions. The main nickel-related level is at Ev+0.32 eV. Levels at Ev+0.15 and Ev+0.54 eV are not related to nickel while those at Ev+0.50 and Ev+0.28 eV may be nickel related. Their concentrations depend on the quenching mode. There is no nickel-related level in the upper half of the band gap. The complicated annealing behavior of the main nickel-related level is explained on the basis of the formation and dissociation of a nickel-vacany complex.
