Item A clinico-epidemiological study of the first outbreak of Nipah virus in India – report from ground zero(Siddharth Health Research and Social Welfare Society, 2020-06) Saha, R; Mitra, S; Halder, S; Deb, J; Patra, A; Sarkar, GNIntroduction: The first Nipah Virus (NiV) outbreak occurred in India in the year 2001 at Siliguri. The second outbreak happened at Nadia in 2007. Nipah Virus exhibits neurological and pneumonic tropism with the predominant clinical presentation being encephalitis in humans. Material and Methods: The present study was a record based prospective study on 67 cases admitted with pyrexia of unknown origin in North Bengal Medical College during the period from 18.02.2001 to 30.02.2001 and a parallel study on epidemiological record carried out by PSM department also taken into account. All necessary investigations including autopsy examination, pathological, and microbiological study were done. Results: There was a clustering of cases around Bhaktinagar. There was a strong H/O Medinova Nursing Home Contact among the patients. 18 out of 20 cases were staff of that Nursing Home. Serum samples tested show NiV specific IgM and IgG in 9 out of 17 samples with one sample which was positive for IgG only suggesting past infection. The cases were admitted with predominant neurological symptoms (53.73% cases) but about 80% recovered with no residual neuro deficit. The natural reservoir of NiV is present in Bangladesh and in Northern India. Conclusion: When NiV infection is suspected, infection control practices must be strengthened to avoid an outbreak in a hospital setting. Here the present study is presenting the experience in the first outbreak of the Nipah virus in India at Siliguri for awareness of clinical personnel to control further outbreak at the very beginning.Item Evaluation of trans thoracic invasive diagnostic procedures in 50 adult patients of mediastinal diseases(Siddharth Health Research and Social Welfare Society, 2019-08) Biswas, S; Saha, R; Deb, J; Dey, PIntroduction: Mediastinum is a “Pandora’s box” with many neoplastic and nonneoplastic lesions. Clinico-radiological pattern of mediastinal diseases depends on the size, location and etiology. Hence, non-invasive approach to these cases sometimes leads to diagnostic dilemma. Aims: A prospective study was performed over a 1-year period with the objective of evaluation of diagnostic yields and risk of trans thoracic ultra sound (TTUS) and computed tomography (CT) guided fine‑needle aspiration cytology (FNAC) and Tru-cut biopsy along with comparison of cost-effectiveness among mediastinal diseases where clinical and non-invasive imaging could not conclude the diagnosis. Materials and Methods: A prospective study of mediastinal diseases of the adult population without having any diagnosis admitted in a tertiary care hospital in Eastern India was performed after clearance of the ethical committee of the institute. Fifty cases of mediastinal diseases were seen during the study period. One patient sometimes had undergone more than one procedure. The choice of a procedure depended upon the location of the lesion, nature of disease and complication and cost effectiveness ofthe procedures. During the calculation of diagnostic yield of procedure, conclusive results and concordant results to more invasive procedures were considered. Results: Among 50 patients diagnostic yield of TTUS guided FNA and Tru-cut biopsy were 60% and 63.6% respectively. Diagnostic yield of Thoracic CT guided FNA and Tru-cut biopsy were 85% and 92.3% respectively. As a whole TTUS guided invasive procedure and Thoracic CT guided invasive procedure had a diagnostic yield of 61.5% and 87.9% respectively. Complication is less in CT guided invasive procedures (9.1%) compared to Transthoracic USG guided invasive procedures (11.5%) and complication is more common in Tru-Cut biopsy (16.7%) than fine needle aspiration (5.7%). Conclusion: Tru-cut biopsy if applicable is much superior to FNAC for a definite diagnosis of the mediastinal diseases. TTUS guided invasive procedures are very much cost-effective and have added advantage of real time guidance and is comparable with CT guided invasive procedures in respect to risk and diagnostic yields.Item A rare case of primary adenoid cystic carcinoma of lung.(2014-07) Mukherjee, S; Dattachaudhuri, A; Bhanja, P; Deb, J; Begum, S; Bhuniya, S; Nandi, SA 33-year-old male presented with repeated episodes of blood-streaked sputum for last one-and half-year. Chest radiograph showed consolidation in the right lower zone. Fibreoptic bronchoscopy revealed an endoluminal growth in the right lower lobe bronchus. Histopathological examination of bronchoscopic biopsy specimen confirmed adenoid cystic carcinoma.
