Abstract
BACKGROUND Kolkata is one of the polluted metropolitan cities in India where health effects of air pollution are raising serious concern. OBJECTIVES Purpose of the present study was to analyze association between levels of air pollutants and pulmonary function of adult males living in two different air pollutant zones of Kolkata. METHODS Air pollution data of two ambient air quality monitoring stations located at Rabindrabharati and Victoria Memorial was collected from West Bengal Pollution Control Board, Kolkata for the period from January to March 2012. Study was conducted on 200 males (17-22 yrs), subdivided into two groups from living within 3 km radius of that two monitoring stations. They were investigated for their spirometric lung functions following method and technique recommended by American Thoracic Society. Results were expressed as mean ± SD and independent samples T test was conducted to compare between groups. RESULTS PM10, SO2 concentrations were significantly higher in Rabindrabharati zone, whereas no significant differences were noted in NO2 and CO concentrations though values were higher at Rabindrabharati than Victoria Memorial. FVC, FEV1, FEF25-75%, MVV were significantly lower in males of Rabindrabharati zone. CONCLUSION Exposure to high air pollutant concentration might be associated with reduced pulmonary function in adult males.

Abstract
INTRODUCTION Widespread PSA (prostate specific antigen) screening has resulted in stage migration of prostate cancer. Smaller tumor volumes are being detected in radical prostatectomy specimens. This has coincided with increasing reports about the 'vanishing cancer phenomenon.' AIMS To analyse the cases of robot assisted laparoscopic prostatectomy (RALP) at our institute in which the pre operative prostate biopsy was positive for adenocarcinoma but no tumor could be identified in the final histopathology, and to review the literature for possible reasons for such a phenomenon. MATERIALS AND METHODS Nine patients were identified out of a total of 184 cases of RALP in which the final histopathology did not correlate with the initial biopsy report. The initial biopsy slides as well as the final histopathology slides were reviewed by a second pathologist. The specimens were processed in entirety and additional sections were taken until no tissue was left. RESULTS Two patients had cancer diagnosed on TURP (transurethral resection of prostate) chips, while the remaining patients had undergone TRUS biopsy for elevated PSA. The final histopathological diagnosis was benign prostatic hyperplasia in two patients, chronic prostatitis in four patients, and acute florid prostatitis in one patient, granulomatous prostatitis with glandulostromal hyperplasia in one patient and TCC (transitional cell carcinoma) of prostate in one patient. CONCLUSION Most cases of pT0 are due to inability of routine histopathological analysis to identify minute tumor focus. Urologists need to be aware of this in view of the potential medico legal implications.

Abstract
Atlantoaxial fixation is a relatively rare cause of torticollis which may be easily missed in practice. Early diagnosis is important as this indicates a compromised atlantoaxial complex with the potential to cause neural damage or even death. Here, we report a case of atlantoaxial rotatory fixation in a 13 yr old male with torticollis for two years and history of defaulting treatment for tubercular lymphadenitis. In this case, the odontoid peg view revealed asymmetric distance between the odontoid and lateral mass of atlas which was confirmed with Fluoroscopy and Computed Tomography (CT) scan. Magnetic Resonance Imaging (MRI) was also done which showed hyperintensity in alar ligaments with posterior inclination of the odontoid peg along with cervical lymphadenopathy.

Abstract
AbstractIn order to simulate the performance of the present day state-of-the-art multijunction solar cells in its entirety, an integrated electrical-optical model has been developed. The one-dimensional ab initio electrical model for the analysis of the transport properties of such devices can handle a very general semiconductor device structure where the material properties vary with position and the gap state properties with position and energy. The original semi-empirical optical model used takes into account both specular interference effects, and diffused reflectances and transmittances due to interface roughness. The latter are derived from angular-resolved photometric measurements and used as input parameters to the numerical programme. Comparison of the illuminated current density-voltage (J-V) characteristics, calculated on the basis of (a) a simple exponential absorption law and (b) the optical model, reveals an increase of ˜1 mA cm−2 in the short-circuit current and ˜8% in the cell conversion efficiency for case (b). Also the long wavelength quantum efficiency (QE) shows a marked improvement, while the blue QE decreases since proper account is taken of the absorption in the transparent conducting oxide and reflection from the device. The combined model is being applied to simulate the characteristics of wideband-gap-emitter-layer solar cells deposited in a three chamber conventional glow discharge reactor onto (i) highly textured SnO2 and (ii) weakly textured indium tin oxide substrates. The cells have been characterised experimentally by J-V and QE measurements. Preliminary results indicate that the integrated model matches the experimental J-V and QE data with a more realistic set of material parameters as compared to case (a).

Abstract
Gastrointestinal stromal tumours (GISTs) are rare tumours but are the commonest mesenchymal neoplasms in the gastrointestinal tract. To our knowledge, there is no large case series in Asian countries in which a clinico-radiological descriptive analysis of these tumours has been carried out. In this retrospective study, we analysed our experience of 70 patients with histopathologically proven GISTs, who were presurgically investigated by using CT, and describe the demography, anatomical distribution, imaging features and clinical course of the GIST. We found an unusually large predominance of males in our study, stomach and small bowel appeared to have been involved similarly and small bowel tumours had a higher rate of metastases. We also highlight some unusual CT features of these tumours that we encountered during the study, such as the presence of metastatic lymphadenopathy and satellite nodules, relapse in appendices epiploicae of the bowel, metachronous liposarcoma, adrenal and lung metastases, multiplicity of lesions and aneurysmal dilatation of the bowel. Two of our patients also had multiple neurofibromas, whose association with GIST has been seen in earlier reports. To the best of our knowledge, this article presents one of the largest series of articles on GISTs, to date, in Asian countries. We conclude with a differential diagnosis of GIST, with salient features distinguishing each entity.
