Abstract
A 38-year-old female on Vitamin D therapy presented with hypercalcemia induced acute kidney injury. Evaluation revealed primary hyperparathyroidism (PHPT) and iatrogenic hypervitaminosis D. After medical stabilization, she underwent surgical removal of the parathyroid adenoma, and made a full recovery. This case highlights unmasking of subclinical hyperparathyroidism by vitamin D therapy leading to severe hypercalcemia.

Abstract
OBJECTIVE To evaluate the diagnostic accuracy and safety of magnetic resonance imaging (MRI)-guided percutaneous biopsy of mediastinal masses performed using a wide-bore high-field scanner. MATERIALS AND METHODS This is a retrospective study of 16 consecutive patients (8 male, 8 female; mean age 74 years) who underwent MRI-guided core needle biopsy of a mediastinal mass between February 2010 and January 2014. Size and location of lesion, approach taken, time for needle placement, overall duration of procedure, and post-procedural complications were evaluated. Technical success rates and correlation with surgical pathology (where available) were assessed. RESULTS Target lesions were located in the anterior (n = 13), middle (n = 2), and posterior mediastinum (n = 1), respectively. Mean size was 7.2 cm (range 3.6-11 cm). Average time for needle placement was 9.4 min (range 3-18 min); average duration of entire procedure was 42 min (range 27-62 min). 2-5 core samples were obtained from each lesion (mean 2.6). Technical success rate was 100%, with specimens successfully obtained in all 16 patients. There were no immediate complications. Histopathology revealed malignancy in 12 cases (4 of which were surgically confirmed), benign lesions in 3 cases (1 of which was false negative following surgical resection), and one inconclusive specimen (treated as inaccurate since repeat CT-guided biopsy demonstrated thymic hyperplasia). Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in our study were 92.3, 100, 100, 66.7, and 87.5%, respectively. CONCLUSION MRI-guided mediastinal biopsy is a safe procedure with high diagnostic accuracy, which may offer a non-ionizing alternative to CT guidance.

Abstract
BACKGROUND Hepatitis A virus (HAV) and Hepatitis E virus (HEV) are both enterically transmitted, resulting in acute viral hepatitis (AVH) in developing countries. They pose major health problems in our country. This study was done to determine prevalence of HAV and HEV in patients presenting with AVH and the co-infection of HAV and HEV in these patients. MATERIALS AND METHODS A cross-sectional study of 2-years duration was conducted in the Department of Microbiology, KMC, Mangalore. A non-random sampling of 958 patients presenting with AVH was considered in the study. On the basis of history, serum samples were analysed for IgM anti-HAV and IgM anti-HEV for the detection of HAV and HEV, respectively using commercially available ELISA kits. Data collected was analysed by using Statistical Package for the Social Sciences (SPSS) version 11.5. RESULTS The seroprevalence of HAV- and HEV-positive patients were 19.31% and 10.54%, respectively. The seroprevalence of both HAV and HEV in patients with acute viral hepatitis was 11.5%. The prevalence of HAV and HEV among males (68% and 31%) was higher than in females (31% and 20%) and was predominantly seen among young adults. These infections were predominantly seen during end of monsoons and beginning of winter. CONCLUSION Though the prevalence of HAV is much higher than that of HEV, co-infection rate of 11.5% mandates the screening for HEV which will be of immense importance in pregnant women and improving levels of personal hygiene among higher socio-economic population. These data will be essential for planning of future vaccination strategies and for better sanitation programme in this part of the country.

Abstract
Fungal infections of the urinary tract are usually encountered following prolonged antibiotic use, instrumentation and indwelling urinary catheters. These type of infections are mostly seen in immuno-compromised patients. Candida is the most common among the fungal infections of urinary tract followed by Aspergillus infection. Here is a case report of a 26 year old diabetic female who presented with abdominal pain, fever, nausea and vomiting. She had undergone double-J stenting 15-20 days back. The cause of the symptoms was not detected till the patient underwent C.T Scan-KUB with excretory urography which showed the displaced D-J stent. Then on performing replacement of D-J stent, cystoscopy was done and the tissue sample was sent for microbiological and histopathological examination. On Microbiological examination, Aspergillus flavus was isolated from the tissue, which was culprit behind the disease. Patient was then treated with anti-fungal drugs, following which she gradually improved.

Abstract
The shortage of donors in cardiac transplantation may be alleviated by the use of allografts from donation after circulatory death (DCD) donors. We have previously shown that hearts exposed to 30 min warm ischemic time and then flushed with Celsior supplemented with agents that activate ischemic postconditioning pathways, show complete recovery on a blood-perfused ex vivo working heart apparatus. In this study, these findings were assessed in a porcine orthotopic heart transplant model. DCD hearts were preserved with either normothermic ex vivo perfusion (NEVP) using a clinically approved device, or with standard cold storage (CS) for 4 h. Orthotopic transplantation into recipient animals was subsequently undertaken. Five of six hearts preserved with NEVP demonstrated favorable lactate profiles during NEVP and all five could be weaned off cardiopulmonary bypass posttransplant, compared with 0 of 3 hearts preserved with CS (p < 0.05, Fisher's exact test). In conclusion, DCD hearts flushed with supplemented Celsior solution and preserved with NEVP display viability before and after transplantation. Viability studies of human DCD hearts using NEVP are warranted.

Abstract
Donation after circulatory death (DCD) offers a potential additional source of cardiac allografts. We used a porcine asphyxia model to evaluate viability of DCD hearts subjected to warm ischemic times (WIT) of 20–40 min prior to flushing with Celsior (C) solution. We then assessed potential benefits of supplementing C with erythropoietin, glyceryl trinitrate and zoniporide (Cs), a combination that we have shown previously to activate ischemic postconditioning pathways. Hearts flushed with C/Cs were assessed for functional, biochemical and metabolic recovery on an ex vivo working heart apparatus. Hearts exposed to 20-min WIT showed full recovery of functional and metabolic profiles compared with control hearts (no WIT). Hearts subjected to 30- or 40-min WIT prior to C solution showed partial and no recovery, respectively. Hearts exposed to 30-min WIT and Cs solution displayed complete recovery, while hearts exposed to 40-min WIT and Cs solution demonstrated partial recovery. We conclude that DCD hearts flushed with C solution demonstrate complete recovery up to 20-min WIT after which there is rapid loss of viability. Cs extends the limit of WIT tolerability to 30 min. DCD hearts with ≤30-min WIT may be suitable for transplantation and warrant assessment in a transplant model.

Abstract
Objectives To review the terminology, clinical features, and management of temporal bone osteomyelitis. Design and Setting Prospective study in a tertiary care center from 2001 to 2008. Participants Twenty patients visiting the outpatient department diagnosed with osteomyelitis of the temporal bone. Main Outcome Measures The age, sex, clinical features, cultured organisms, surgical interventions, and classification were analyzed. Results Of the 20 cases, 2 (10%) were diagnosed as acute otitis media. Eighteen (90%) had chronic otitis media. Nineteen (95%) were classified as medial temporal bone osteomyelitis and one (5%) as lateral temporal osteomyelitis. The most common clinical features were ear discharge (100%), pain (83%), and granulations (100%). Facial nerve palsy was seen in seven cases (35%) and parotid involvement in one case. Ten patients (56%) had diabetes mellitus. The organisms isolated were Pseudomonas aeruginosa (80%) and Staphylococcus aureus (13.33%). Histopathology revealed chronic inflammation in 20 patients (100%) and osteomyelitic bony changes in 14 (70%). Surgical debridement was the most preferred modality of treatment (87%). Conclusion A new classification of temporal bone osteomyelitis has been proposed. Bacterial cultures must be performed in all patients. Antibiotic therapy is the treatment of choice. Surgical intervention is necessary in the presence of severe pain, complications, refractory cases, or the presence of bony sequestra on radiology.

Abstract
BACKGROUND AND METHODS We describe a method for obtaining pharmacokinetics (PK) and pharmacology data from adult zebrafish in terms of mg/kg using a novel method of oral administration. Using carbamazepine (CBZ) as a test drug, we employed dried blood spot (DBS) cards to enable drug quantification for PK; and we evaluated the pharmacological anxiolytic effect using novel tank test. RESULTS The PK study confirmed the presence of CBZ in both blood and brain and the behavioural study showed dose dependent anxiolytic effect. The reproducibility of oral dosing was confirmed by the fact that the results obtained in both the experiments had negligible errors. CONCLUSIONS This report enables a novel approach for optimizing the utility of zebrafish in drug discovery and drug delivery research.
