Study of histopathological pattern of endometrium in abnormal uterine bleeding and its management

Background: Abnormal uterine bleeding is one of the most common and challenging problems presenting as an enigma to the gynecologist regardless of the age of the women.  Histopathological evaluation of endometrium plays a significant and pivotal role in the diagnosis and management of endometrial causes of Abnormal Uterine Bleeding. The main aim was to study the frequency of different histopathological patterns of endometrium in patients with abnormal uterine bleeding across different age groups, know the endometrial causes of abnormal uterine bleeding and its managements.Methods: This study was conducted on 300 patients from March 2014 to February 2015 in the department of Obstetrics and Gynaecology in a reputed teaching hospital and research centre in South India. Demographic indices were collected and recorded. Endometrial samples were sent for histopathological examinations and different endometrial patterns were noted.Results: Abnormal Uterine Bleeding (AUB) presented mostly in the 41-50 years age spectrum (48.6%) and most of the patients were multipara. The main presenting complaint among our patients was menorrhagia (42%) followed by polymenorrhagia (15%), menometrorrhagia (10.6%) ,continuous vaginal bleeding (9.6%), Polymenorrhea (9.3%), postmenopausal bleeding (8.6%) and metrorrhagia (4.6%).The commonest histopathological  pattern in abnormal uterine bleeding was  normal physiological phases of menstrual cycle - proliferative and secretary endometrium (37% and 30%  respectively). Endometrial hyperplasia was the most common endometrial pathology observed (22.6%).Conclusions: Endometrial evaluation in abnormal uterine bleeding in different age groups helps in the management, especially in the perimenopausal and postmenopausal age groups to rule out premalignant conditions and malignancy

The Lax conjecture is true

In 1958 Lax conjectured that hyperbolic polynomials in three variables are determinants of linear combinations of three symmetric matrices. This conjecture is equivalent to a recent observation of Helton and Vinnikov.Comment: 7 pages, Proceedings to the AMS, to appear. Added background materia

Sentiment analysis by deep learning approaches

We propose a model for carrying out deep learning based multimodal sentiment analysis. The MOUD dataset is taken for experimentation purposes. We developed two parallel text based and audio basedmodels and further, fused these heterogeneous feature maps taken from intermediate layers to complete thearchitecture. Performance measures–Accuracy, precision, recall and F1-score–are observed to outperformthe existing models

Thermodynamic structure of the Atmospheric Boundary Layer over the Arabian Sea and the Indian Ocean during pre-INDOEX and INDOEX-FFP campaigns

Spatial and temporal variability of the Marine Atmospheric Boundary Layer (MABL) height for the Indian Ocean Experiment (INDOEX) study period are examined using the data collected through Cross-chained LORAN (Long-Range Aid to Navigation) Atmospheric Sounding System (CLASS) launchings during the Northern Hemispheric winter monsoon period. This paper reports the results of the analyses of the data collected during the pre-INDOEX (1997) and the INDOEX-First Field Phase (FFP; 1998) in the latitude range 14°N to 20°S over the Arabian Sea and the Indian Ocean. Mixed layer heights are derived from thermodynamic profiles and they indicated the variability of heights ranging from 400m to 1100m during daytime depending upon the location. Mixed layer heights over the Indian Ocean are slightly higher during the INDOEX-FFP than the pre-INDOEX due to anomalous conditions prevailing during the INDOEX-FFP. The trade wind inversion height varied from 2.3km to 4.5km during the pre-INDOEX and from 0.4km to 2.5km during the INDOEX-FFP. Elevated plumes of polluted air (lofted aerosol plumes) above the marine boundary layer are observed from thermodynamic profiles of the lower troposphere during the INDOEX-FFP. These elevated plumes are examined using 5-day back trajectory analysis and show that one group of air mass travelled a long way from Saudi Arabia and Iran/Iraq through India before reaching the location of measurement, while the other air mass originates from India and the Bay of Bengal

Experimental Evidence of Time Delay Induced Death in Coupled Limit Cycle Oscillators

Experimental observations of time delay induced amplitude death in a pair of coupled nonlinear electronic circuits that are individually capable of exhibiting limit cycle oscillations are described. In particular, the existence of multiply connected death islands in the parameter space of the coupling strength and the time delay parameter for coupled identical oscillators is established. The existence of such regions was predicted earlier on theoretical grounds in [Phys. Rev. Lett. 80, 5109 (1998); Physica 129D, 15 (1999)]. The experiments also reveal the occurrence of multiple frequency states, frequency suppression of oscillations with increased time delay and the onset of both in-phase and anti-phase collective oscillations.Comment: 4 aps formatted RevTeX pages; 6 figures; to appear in Phys.

Overview of dry fish landings and trade at Visakhapatnam Fishing Harbour

Fish drying is an age old practice and was adopted as a practical method of preserving fish that have not been immediately consumed or sold in the fresh market. Improved fishing techniques and infrastructure resulted in increased fish catch, better marketing, processing and curing facilities. The advent of multiday trawling at the Visakhapatnam Fishing Harbour further boosted the availability of fish and its processing into value added products. However, drying still remains the cheapest and popular mode of fish preservation

Gravitational and electromagnetic fields of a charged tachyon

An axially symmetric exact solution of the Einstein-Maxwell equations is obtained and is interpreted to give the gravitational and electromagnetic fields of a charged tachyon. Switching off the charge parameter yields the solution for the uncharged tachyon which was earlier obtained by Vaidya. The null surfaces for the charged tachyon are discussed.Comment: 8 pages, LaTex, To appear in Pramana- J. Physic

Anchor Piled Footings – An Alternative Foundation Technique in Expansive Soils

A search for alternative foundation systems inexpansive soils has been continued since their problems wererecognized all over the world. Despite the availability of a goodnumber of remedial techniques, their adoptability andeffectiveness under varied geographical and climatic conditionshave remained questionable. The present paper discusses the fieldinvestigations on the recently promulgated technique of anchorpiled footings in expansive soils. These studies have revealed thatthe granular anchor piles exhibit promising pullout capacity evenunder fully wet condition compared to conventional concrete piles.The heave of model footings provided with granular anchor pilesdecreased by about 73-93% while for footings provided withconventional concrete piles the heave value is decreased by 40 -75%. It is felt from this study that the above technique of anchorpiled footings can be an effective alternative to conventional pilefoundations in expansive soils

Pneumatic Radial Loading To Ease Preloading – An Innovative Technique

Soft ground improvement gained prominence all overthe world in view of ever growing engineering activities forvarious purposes. In view of serious problems during and afterconstruction in these deposits, vertical drains method usingpreloading is being frequently applied to improve these soil beds.However, in view of the difficulties associated with this technique,an alternative vacuum preloading technique was developed. Butvacuum preloading is also limited to the available atmosphericpressure with inevitable technical difficulties. The present paperdiscusses an innovative technique of applying radial pneumaticpressure with the help of inflatable balloons/tubes. The drainageis facilitated along the surface of inflatable tubes by providingfabric strips/the traditional strip drains. The laboratoryexperimentation in test tank indicated that this technique has thepotential for practical applications
