Delayed Presentation of Traumatic Diaphragmatic Rupture with Herniation of the Left Kidney and Bowel Loops
Amiya Kumar Dwari,Abhijit Mandal,Sibes Kumar Das,Sudhansu Sarkar
Case Reports in Pulmonology , 2013, DOI: 10.1155/2013/814632
Abstract: Rupture of the diaphragm mostly occurs following major trauma. We report a case of delayed presentation of traumatic diaphragmatic hernia on the left side in a 44-year-old male who presented two weeks after a minor blunt trauma. Left kidney and intestinals coils were found to herniate through the diaphragmatic tear. This case demonstrates the importance of considering the diagnosis in all cases of blunt trauma of the trunk. It also illustrates the rare possibility of herniation of kidney through the diaphragmatic tear. 1. Introduction Traumatic diaphragmatic hernias (DH) represents only small percentage of all diaphragmatic hernias but it is no longer an uncommon entity. Injury is mostly caused by severe blunt or penetrating trauma [1]. DH may be recognized during the period of hospitalization immediately following trauma. If the diaphragmatic injury is not recognized during the immediate posttraumatic period, the patient may recover and remain symptom free or present either with chronic thoracoabdominal symptoms or with acute emergency due to intestinal strangulation [2]. During the delayed presentation with chronic thoracoabdominal symptoms, the trauma responsible for the injury is often forgotten and the diagnosis is not suspected. A careful history, physical examination, and awareness of the possibility are the prerequisite for timely diagnosis. Abdominal organs that commonly herniate are stomach, spleen, liver, mesentery, and small and large bowels. Kidney is rarely found to herniate through the diaphragmatic tear [3]. The case is unique due to occurrence of the DH with minor trauma, its delayed presentation, and herniation of the left kidney into the thorax. 2. Case Report A 44-year-old male patient was kicked in his left lower chest and upper abdomen by a neighbour during a family quarrel. Considering it to be a minor trauma, he continued his daily activities for the next two weeks. He presented to pulmonary medicine outpatient department with left sided dull aching chest pain and nonproductive cough for ten days. There was no history of abdominal pain or haematuria. On examination, he was afebrile but dyspneic (MMRC grade 2) with respiratory rate of 22 breaths/min, oxygen saturation of 96% with room air, pulse rate of 90/min, and blood pressure of 138/84?mm of Hg. On examination of the chest, there was dull note over left infraclavicular area and bowel sounds were audible over the left side of the chest. Examination of other systems was within normal limits. His chest X-ray PA view revealed a heterogeneous opacity in left lower zone but no
Diagnosis of three cases of endobronchial tuberculosis presenting as unresolved pneumonia, following fiberoptic bronchoscopic biopsy
Roy Partha,Dey Subir,Sarkar Anirban,Dwari Amiya
Lung India , 2010,
Abstract: Nowadays, endobronchial tuberculosis is of rare occurrence. This article presents three such cases. All of them presented as unresolved pneumonia with collapse-consolidation in chest X-ray. All the three patients were sputum smear negative for acid fast bacilli. Diagnosis was possible only with fiberoptic bronchoscopy and bronchial biopsy.
On utilization of seismic resistance of masonry infills in design of lowrise mixed r.c. buildings -A case study
Amiya Kumar Samanta
Journal of Engineering and Applied Sciences , 2009,
Abstract: In early stage of civilization, people constructed mostly masonry buildings based on those low-engineered and empirical approaches. In design of new buildings, the structural behaviour of masonry elements is of interest mostly in case of infilled frames or mixed RC frames, where masonry element are also being utilized as participating in structural behaviour of the building. The infilled frames show larger ductility than isolated masonry walls. Very few codes have made provisions on RC frames with brick masonry infill. Euro code (8) and Nepal Building Code (201) make some provisions for ordinary building up to three storey in the low seismic zones, whereas the Indian seismic code IS: 1893 recommends linear elastic analysis for the bare RC frames excluding the effect of brick infill. In the present case study, the author makes an attempt to evaluate contributions of such infill on RC frames using the literature of Aliaari (2005) and effectively utilizes in design of mixed masonry RC frame structures.

Simultaneous occurrence of disseminated superficial, linear and hypertrophic verrucous forms of porokeratosis in a child
Mukhopadhyay Amiya Kumar
Indian Journal of Dermatology, Venereology and Leprology , 2004,
Abstract: Porokeratosis is a genodermatosis characterized by abnormal epidermal keratinization with the histological feature of cornoid lamella. There are many clinical variants, but two or more of these variants rarely occur in a single patient. This variation in clinical presentation may be due to the different phenotypic expression of a common genetic abnormality or may be the consequence of abnormalities in closely linked genetic loci or genes. Here we report about a child who showed simultaneous occurrence of disseminated, linear and hypertrophic verrucous lesions of porokeratosis. He also had genital lesions, reported uncommonly in the medical literature.

Indian Journal of Dermatology , 2004,
Abstract: Granuloma multiforme is an uncommon disorder, which has been described primarily in Central Africa. It may cause diagnostic confusion with granuloma annulare, tuberculoid and some other disorders. A rare report of granuloma multiforme in 48 year old lady is presented.
PREPARATION OF SILVER NANOPARTICLE BY MICROORGANISM AND ITS APPLICATION IN PHARMACY
Amiya Kumar Prusty
International Journal of Biomedical and Advance Research , 2011, DOI: 10.7439/ijbar.v2i1.20
Abstract: Materials by changing their size from normal to nanometer range shows a great change in their physicochemical properties primarily due to their small size and large specific surface area. A number of techniques have been reported for the preparation of metallic nanoparticles but there is a great need to develop environmentally benign nanoparticle synthesis processes without use of toxic chemicals. Therefore use of biological systems for preparation of nanoparticle is considered as a best solution where use of toxic chemicals and harsh preparation methods can be avoided. Silver nanoparticles can be prepared by bioreduction process using bacteria, actinomycetes and fungi etc very efficiently. The silver nanoparticles formed are having efficient antimicrobial activity.
Use of Electrochemically Machined Porous Silicon to Trap Protein Molecule
Amiya Kumar Patel
Research Journal of Applied Sciences, Engineering and Technology , 2010,
Abstract: Silicon surface chemistry is crucial to allow access to technologically interesting thin films not only for electronic industries but also for biological applications. Silicon wafers were etched electrochemically using ethanolic HF solution under different current densities (143 to 714 mA.cm-2) while etching time was adjusted to obtain a constant charge of 4.5 C.cm-2 to generate pores of different sizes (50 to 1500 nm). Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) studies revealed the properties of porous layer such as pore distribution, diameter, geometric shape of the pores, which depend upon HF concentration, current density during electrochemical etching, temperature etc. Stability of the porous silicon wafer was achieved by thermal oxidation. In this study, attempted were made to determine whether porous silicon can be used to bind protein reversibly. Admittance and visualization of the protein (i.e. Bovine serum albumin) adsorption in pH gated admission experiments were determined by atomic force microscopy. It was observed that the 66 kDa BSA protein (~15 nm diameter) when positively charged (i.e. with citrate buffer, pH 4) would evenly coat the negatively charged surface of an oxidized porous silicon. The bound protein could be eluted under conditions that imparted a net negative charge on bound BSA (i.e., with phosphate buffered saline, pH 7). Thus, the electrochemically machined porous silicon can be used as molecular sieve to trap protein molecule, which could allow the in vitro study of protein-protein interactions.
