Comparison of Radiographs is routinely used for identification of deceased all over the world. Even though dental radiographs are used most often, other x-rays have also been shown to be of use. In the present case, the review chest X-ray of a patient showed a radiographic picture at variance with the one taken only 28 days earlier. This aroused the suspicion of the clinician. Forensic comparison was used to resolve this issue. © 2014 South India Medico-Legal Association. All rights reserved. Source

Background: Pleural effusion is a common diagnostic dilemma for the pulmonologist. A histological diagnosis would many a time steer the way to an accurate diagnosis of the aetiologies of pleural effusions. This study has compared two methods for obtaining histological specimens in cases of undiagnosed pleural effusions. Aim: To compare the efficacy of closed pleural biopsy with Abrahm's needle and medical thoracoscopic biopsy in the diagnosis of undiagnosed exudative pleural effusions at a tertiary care setting. Study Design: Randomized controlled study. Study Period: November 2008-October 2010. Methodology: All patients who were admitted with pleural effusions underwent a clinical workup for pleural effusions. Light's criterion was used to differentiate between exudative and transudative pleural effusions. Those patients with exudative pleural effusions, who did not have a specific diagnosis, were included in the study. Fifty eight patients were included in the study and they were randomized into 2 Groups of 29 patients each. One group was subjected to medical thoracoscopic pleural biopsy and the other to closed pleural biopsy with Abrahm's needle. Demographic, clinical and biochemical characteristics, diagnostic yields and the complications among the two groups were compared. Result: Medical thoracoscopy has a diagnostic yield of 86.2% with complication rate of 10.3% compared to 62.1% and 17.2% respectively in closed pleural biopsy group. Conclusion: Medical thoracoscopic pleural biopsy had a better diagnostic yield with a lower complication rate as compared to closed pleural biopsy with Abrahm's needle. Source

The aim of this review paper is to emphasis Computer Aided Inspection (CAI) system for the detection of defects in food products. As the food products are being consumed directly (processed / Unprocessed) by human beings, defects in food products cause serious health hazards which insists to develop an inspection system which facilitates for food products of high quality and safety standards. CAI system provides an alternative for an automated, non-destructive and cost effective technique to accomplish accurate, fast and objective quality determination. This CAI system is based on image Analysis and processing which can be adopted in food industry. The various stages of CAI system consists of preprocessing, enhancement, segmentation, feature extraction and classification. Considerable research as proven its potential for inspection and grading of fruits, meat, vegetables, grain, bakery products, confessionary products and processed food products. This paper reviews the recent development and advances of CAI in the food industry. The fundamental elements of the system and technology are examined. © IEEE 2013. Source

Australian guidelines recommend that tailings materials from uranium (U) mining and milling be contained without any detrimental impact on the environment for at least 1000 years. Natural analogue sites are being investigated to determine if they can provide data on the rates of natural erosion processes which occur over these timescales, for input into predictive geomorphic computer models. This paper presents radionuclide, metal and stable lead (Pb) isotope data from sediment cores and surface soils in the vicinity of two mineralised areas in the Alligator Rivers Region. Surface scrapes from the natural Anomaly #2, south of the Ranger mineral lease, exhibit radiogenic 206Pb/ 207Pb and 208Pb/ 207Pb ratios, and elevated U and metal concentrations typical for a near surface U anomaly. In contrast, samples taken from the Koongarra mineral lease (KML) show radionuclide activity and metal concentrations similar to natural areas elsewhere in the Alligator Rivers Region and Pb isotope ratios are closer to present day average crustal ratios (PDAC), as the orebodies at KML are covered by surficial sand. A sediment core collected from Anbangbang Billabong, downstream of KML, exhibits small variations in Pb isotope ratios that indicate that approximately 1% of the upper sediments in the sediment core may be derived from material originating from the U anomaly at Koongarra. © 2010 Elsevier Ltd.

Objective: To study the course and complications of hepatitis A in children. Methods: Seventy eight children diagnosed as acute viral hepatitis A by IgM antiHAV were prospectively studied for involvement of other systems and complications. Results: The mean age of children was 7.85±3.4 y. Jaundice was present in all the patients as this was the inclusion criteria. Fever was present in 82.1%, hepatomegaly in 98.7% and splenomegaly in 39.7%. More than 5 fold rise in Aspartate transaminase (AST) and Alaninetransaminase (ALT), were seen in 62 cases (79.5%) and 55 cases (70.5%) respectively. Coagulopathy (Prothrombin time INR > 1.5) was observed in 12 cases (15.4%) and abnormal APTT in 10 cases (12.8%). Thrombocytopenia was observed in 5.1% of children and 8.9% had more than 2 hematological abnormalities. Ascites was noted in 35 cases (44.9%), gallbladder wall thickening in 32 cases (41%) and pleural effusion in 11 cases (14.1%). Acute renal failure, acute glomerulonephritis and acute pancreatitis were present in 1 case (1.3%) each. Raised CK-MB values more than 3 times the normal was noted in 5 cases (6.4%). On follow up, most of the children recovered completely by 2 mo and prolonged cholestasis was observed in 2 of them. In the present study mortality was 1.3% and it was attributable to fulminant hepatic failure. Conclusions: Eventhough hepatitis A infection is a self-limiting disease, extrahepatic manifestations and mortality are not uncommon. All cases should be followed up till complete recovery and only a strong index of suspicion will enable us to recognize the complications. © Dr. K C Chaudhuri Foundation 2013. Source
