Heavily thickened pericardium with constrictive pericarditis.

A middle-aged male presented with symptoms of exertional shortness of breath and leg swelling for the past six months. Examination revealed raised jugular venous pressure (JVP), pitting pedal oedema, muffled heart sounds, bilateral pleural effusion and hepatomegaly. Echocardiogram showed features of constrictive pericarditis with heavily thickened pericardium, which was confirmed by cardiac computed tomography (CT). The patient underwent pericardiectomy following which echocardiographic features of constriction were reversed and the patient became asymptomatic

Leakage analysis of gasketed flange joints under combined internap pressure and thermal loading

Leakage in Gasketed Flanged Joints (GFJs) have always been a great problem for the process industry. The sealing performance of a GFJ depends on its installation and applied loading conditions. This paper aims to finding the leak rate through ANSI class#150 flange joints using a compressed asbestos sheet (CAS) gasket under combined structural and thermal transient loading conditions using two different leak rate models and two different bolt-up levels. The first model is a Gasket Compressive Strain model in which strains are determined using finite element analysis. The other model is based on Porous Media Theory in which gasket is considered as porous media. Leakage rates are determined using both leak rate models and are compared against appropriate tightness classes and the effectiveness of each approach is presented

Helicobacter pylori infection and micronutrient deficiencies.

It is known that deficiencies of micronutrients due to infections increase morbidity and mortality. This phenomenon depicts itself conspicuously in developing countries. Deficiencies of iron, vitamins A, E, C, B12, etc are widely prevalent among populations living in the third world countries. Helicobacter pylori (H pylori) infection has a high prevalence throughout the world. Deficiencies of several micronutrients due to H pylori infection may be concomitantly present and vary from subtle sub-clinical states to severe clinical disorders. These essential trace elements/micronutrients are involved in host defense mechanisms, maintaining epithelial cell integrity, glycoprotein synthesis, transport mechanisms, myocardial contractility, brain development, cholesterol and glucose metabolism. In this paper H pylori infection in associated with various micronutrients deficiencies is briefly reviewed

Non-compaction of the left ventricle and associated ventricular septal defect.

A case report of a 28-year-old patient, who presented with symptoms and signs of congestive heart failure and had clinical signs of ventricular septal defect as well. On further work-up echocardiogram showed non-compaction of the left ventricle with severe left ventricular systolic dysfunction and a ventricular septal defect. He was treated with standard treatment of heart failure and is doing well

Quadricuspid aortic valve with aortic regurgitation: a rare echocardiographic finding.

We report on a middle-aged woman treated for chronic hepatitis C virus infection with pegylated interferon. Auscultation revealed a diastolic murmur and the peripheral signs of aortic regurgitation. She had shortness of breath on moderate exertion for the past 4 months, which she attributed to her liver disease. Echocardiogram showed a quadricuspid aortic valve with severe aortic regurgitation. She was referred to a cardiothoracic surgeon for aortic valve replacement (AVR). However, she decided against AVR despite detailed counselling, and opted for medical treatment

Web Based E-Learning Solution for Quality Education

Nowadays computers education is necessary in every sector whether it is public or private. General applications like Word processor, Spread sheet, Presentations and email usage is demanded during hiring someone. Under development countries like Pakistan where literacy rate is already low, facing these challenges to produce a quality computer professional. Students have to pay huge amount to get a quality computer training away from their doorstep. Private sector is trying their best to fill this gap for professional education but they offered less quality that leads their efforts towards failure. Students have keen interest to get computers professional education that can help in their future life but they came back with frustration due to low quality of courses offered at high cost. In this situation the frustration can be reduced through Elearning Program. In this paper the author try to offer a web based E-learning solution according to current market requirements. This E-Learning solution may give some hope to those who are tired from current situations
