BACKGROUND & AIMS There is a paucity of data on the impact of hepatitis D virus (HDV) in patients with hepatitis B virus (HBV) infection from South Asia. We studied the impact of HDV co-infection on virological and clinical characteristics. METHODS We collected data of 480 patients with HBsAg positive and a detectable HBV DNA PCR, who presented to the Aga(More)
BACKGROUND Ascitic fluid infection (AFI) in cirrhotic patients has a high morbidity and mortality. It has two variants namely, spontaneous bacterial peritonitis (SBP) and culture negative neutrocytic ascites (CNNA). The aim of this study was to determine the outcome in cirrhotic patients with culture positive (SBP) and culture negative neutrocytic ascites.(More)
Heterometrus xanthopus (Scorpion) is one of the most venomous and ancient arthropods. Its venom contains anti-microbial peptides like hadrurin, scorpine, Pandinin 1, and Pandinin 2 that are able to effectively kill multidrug-resistant pathogens. The present study was conducted to evaluate the anti-bacterial activity of H. xanthopus venom. Six Gram-positive(More)
Upper gastrointestinal (UGI) bleeding secondary to a ruptured splenic artery (SA) pseudoaneurysm into the stomach is a rare but a life-threatening condition. Owing to the low prevalence, it remains a diagnostic and therapeutic challenge. A frail 77-year-old Caucasian female presented with epigastric pain and hematemesis. Endoscopy was non-diagnostic for an(More)
IgA nephropathy is the most common glomerulonephritis worldwide and typically has minimal signs for chronicity in histopathology at the time of initial presentation. Pseudotumor cerebri (PTC) is characterized by increased intracranial pressure in the absence of any intracranial lesions, inflammation, or obstruction. PTC has been reported in renal transplant(More)
BACKGROUND Chronic kidney disease is an increasingly prevalent health problem with the potential for poor outcome of end-stage renal disease. Hospitalized critically ill patients are prone to acute renal injury from numerous factors such as poor renal perfusion secondary to ischemia and hypotension, nephrotoxin exposure, and intravenous contrast exposure.(More)
Background. Uric acid can acutely activate various inflammatory transcription factors. Since high levels of oxyradicals and lower antioxidant levels in septic patients are believed to result in multiorgan failure, uric acid levels could be used as a marker of oxidative stress and poor prognosis in patients with sepsis. Design. We conducted a prospective(More)
OBJECTIVE To assess the diagnostic accuracy of the Rydel-Seiffer tuning fork versus the qualitative 128-Hz tuning fork for detecting sensory axonal neuropathy. METHODS One hundred consecutive patients seen at the Neurology Outpatient Electromyography clinic at a major academic center were recruited and consented for this study. Study personnel who were(More)
Board games, like Tic-Tac-Toe and CONNECT-4, play an important role not only in development of mathematical and logical skills, but also in emotional and social development. In this paper, we motivate and address the problem of generating interesting start states for such games. Our algorithm generates starting states of varying difficulty level for player(More)
would really like to appreciate many peoples who helped me during the project. I would first highly thank my supervisor Ivar Torstensson, Simulation Engineer at Modelon AB who gave me a lot of trust, determination and flexibility throughout the project. I might not be able to deal with such a challenging project without him in such research-oriented(More)
