A Rare Case of Isolated torsion of Haematosalphinx Presenting as Acute Abdomen During Pregnancy

Isolated fallopian tubal torsion is a rare non obstetric cause for pain abdomen during pregnancy.We report a case of a 34 year old second gravida who presented with history of amennorrhoe of 7 months, colicky pain in the left iliac fossa , with 2 episodes of vomiting. A Trans vaginal scan revealed a left ovarian cyst. An emergency laparotomy was performed for suspected torsion or haemorrhage into an ovarian cyst. Surprisingly ovaries were normal and a congested and necrotic left tubal torsion with a tubal collection (haematosalphinx) was identified and a salpingectomy was then performed. The differential diagnosis is discussed and the literature is reviewed as it is a very rare clinical entity

Successful Pregnancy Outcome In Maternal Crigler Najjar Syndrome Type II.

Estimated incidence of Crigler-Najjar syndrome(CNS) is 1 case per 1,000,000 births(1 million). The overall prevalence of CN syndrome is unknown, with only several hundred people reported to have this disease. It is interestingly very rare to encounter a pregnant adult women with congenital jaundice. Pregnancy in CN type II patients is a diagnostic and a therapeutic challenge because of the high risk of bilirubin encephalopathy with serious neurological damage as life-threatening complications for the fetus. To date 8 pregnancy outcome have been reported from 5 women and we report the6 woman with a successful 9 th pregnancy outcome. We have discussed detail history, presentation and management during pregnancy and care of the new born

Using Insights from Psychology and Language to Improve How People Reason with Description Logics

Inspired by insights from theories of human reasoning and language, we propose additions to the Manchester OWL Syntax to improve comprehensibility. These additions cover: functional and inverse functional properties, negated conjunction, the definition of exceptions, and existential and universal restrictions. By means of an empirical study, we demonstrate the effectiveness of a number of these additions, in particular: the use of solely to clarify the uniqueness of the object in a functional property; the replacement of and with intersection in conjunction, which was particularly beneficial in negated conjunction; the use of except as a substitute for and not; and the replacement of some with including and only with noneOrOnly, which helped in certain situations to clarify the nature of these restrictions

A Rare Case of Reversible Encephalopathy Syndrome Accompanying Late Postpartum Eclampsia or Hypertensive Encephalopathy-A Clinical Dilemma

Posterior Reversible Encephalopathy Syndrome (PRES) refers to a clinic-radiologic diagnosis. Clinically it is characterized by non specific symptoms such as headache, confusion, visual disturbances and seizures. The radiological findings in PRES are thought to be due to vasogenic oedema, predominantly in the posterior cerebral hemispheres, and are reversible with appropriate management. We report a case of reversible encephalopathy diagnosed by MRI scan occurring in atypical areas like the caudate and lentiform nuclei of the brain following an uneventful lower segment caesarean section in a normotensive patient, who was successfully treated with antihypertensives, anticonvulsants and supportive treatment. The differential diagnosis of convulsions in the post-partum period is discussed

Uterine spiral artery remodeling involves endothelial apoptosis induced by extravillous trophoblasts through Fas/FasL interactions.

Objective— Invasion of uterine spiral arteries by extravillous trophoblasts in the first trimester of pregnancy results in loss of endothelial and musculoelastic layers. This remodeling is crucial for an adequate blood supply to the fetus with a failure to remodel implicated in the etiology of the hypertensive disorder preeclampsia. The mechanism by which trophoblasts induce this key process is unknown. This study gives the first insights into the potential mechanisms involved. Methods and Results— Spiral arteries were dissected from nonplacental bed biopsies obtained at Caesarean section, and a novel model was used to mimic in vivo events. Arteries were cultured with trophoblasts in the lumen, and apoptotic changes in the endothelial layer were detected after 20 hours, leading to loss of endothelium by 96 hours. In vitro, coculture experiments showed that trophoblasts stimulated apoptosis of primary decidual endothelial cells and an endothelial cell line. This was blocked by caspase inhibition and NOK2, a FasL blocking antibody. NOK2 also abrogated trophoblast-induced endothelial apoptosis in the vessel model. Conclusions— Extravillous trophoblast induction of endothelial apoptosis is a possible mechanism by which the endothelium is removed, and vascular remodeling may occur in uterine spiral arteries. Fas/FasL interactions have an important role in trophoblast-induced endothelial apoptosis

Near-linear Time Algorithm for Approximate Minimum Degree Spanning Trees

Given a graph $G = (V, E)$, we wish to compute a spanning tree whose maximum vertex degree, i.e. tree degree, is as small as possible. Computing the exact optimal solution is known to be NP-hard, since it generalizes the Hamiltonian path problem. For the approximation version of this problem, a $\tilde{O}(mn)$ time algorithm that computes a spanning tree of degree at most $\Delta^* +1$ is previously known [F\"urer \& Raghavachari 1994]; here $\Delta^*$ denotes the minimum tree degree of all the spanning trees. In this paper we give the first near-linear time approximation algorithm for this problem. Specifically speaking, we propose an $\tilde{O}(\frac{1}{\epsilon^7}m)$ time algorithm that computes a spanning tree with tree degree $(1+\epsilon)\Delta^* + O(\frac{1}{\epsilon^2}\log n)$ for any constant $\epsilon \in (0,\frac{1}{6})$. Thus, when $\Delta^*=\omega(\log n)$, we can achieve approximate solutions with constant approximate ratio arbitrarily close to 1 in near-linear time.Comment: 17 page

Content-Based Video Retrieval in Historical Collections of the German Broadcasting Archive

The German Broadcasting Archive (DRA) maintains the cultural heritage of radio and television broadcasts of the former German Democratic Republic (GDR). The uniqueness and importance of the video material stimulates a large scientific interest in the video content. In this paper, we present an automatic video analysis and retrieval system for searching in historical collections of GDR television recordings. It consists of video analysis algorithms for shot boundary detection, concept classification, person recognition, text recognition and similarity search. The performance of the system is evaluated from a technical and an archival perspective on 2,500 hours of GDR television recordings.Comment: TPDL 2016, Hannover, Germany.

Entering the base of the pyramid market in India: A corporate social entrepreneurship perspective

Purpose – The purpose of this paper is to shed light on the international market expansion of multinational corporations (MNCs) to the base of the pyramid (BoP). The authors employ the corporate social entrepreneurship (CSE) perspective to reveal how MNCs can enter this market, the key enabling factors and the benefits they can gain. CSE is related to entrepreneurial and marketing strategies that are inspired by social responsibility. Design/methodology/approach – An exploratory, qualitative multiple-case study has been employed. In-depth interviews were conducted with managers from three MNCs that have entered the BoP market in India. Findings – The findings of this research confirm that successful entry into the BoP requires the pursuit of social responsibility and the adaptation of marketing strategies. In addition, MNCs should identify the key environmental factors (demand conditions and socio-political actors’ expectations) and develop organisational characteristics (management support, network orientation towards non-governmental organisations and availability of financial resources) to match. The findings of this research show that engagement in CSE in countries with considerable BoP populations can bring firms legitimacy and sustainable profitability. Research limitations/implications – This research is based on interviews with a limited number of MNCs in India. Future studies could generalise the findings of this research to a larger number of corporations in other countries. Originality/value – This research brings new insights to the field of international marketing by integrating the corporate social responsibility, marketing and entrepreneurship disciplines. The findings of this research offer empirical support for CSE and its role in international marketing strategies
