Abstract: Background: There has been a sustained increase in the rate of caesarean section in the last few years around the world. Data regarding the current caesarean rate and the trends of its indications in eastern Nepal have not been estimated earlier. Aim: To assess the rate of caesarean sections and the varying indications for caesarean section in a tertiary referral center in eastern Nepal. Methods: All hospital deliveries that took place in BPKIHS between January 2006 and December 2007 were recorded to assess the caesarean section rate and its indications. Results: A total of 5330 deliveries were conducted in 2006. Likewise the total number of deliveries conducted in 2007 was 6634. In 2006 caesarean sections were performed in 28.6% (1524) of all patients. The rate of caesarean sections in 2007 increased and was 33.7% (2239). The most common indication for caesarean section was meconiumstained liquor, which constituted 23.4% (883). The next frequent indication was previous caesarean section, which accounted for 17.2% (650), followed by breech presentation in 11.1% (417), fetal distress in 9.6% (364), non-progress of labor in 7.2% (270), cephalopelvic disproportion in 6.2% (234, and placenta previa in 4.4% (165). Conclusions: There is a increasing trend of performing cesarean section in the tertiary referral center in east era Nepal. The most common indication for cesarean section is meconium-stained liquor.

Abstract: Facial asymmetry can be acquired or congenital. Patients with facial asymmetry are not always functionally disturbed by the malfunction but are usually very much disturbed by their external appearance. Depending on the degree of asymmetry and deformation, the surgical procedure may vary in complexity and extent. The extent of surgery can range from a genioplasty procedure to bimaxillary osteotomy, concomitant with augmentation surgery, genioplasty and craniofacial implants along with mandibular distraction. In severe cases, the soft tissue structures on the affected side may constitute an incredible resistance to stretching and can make the surgery considerably more difficult and liable to relapse. Here we represent a case of post ankylotic facial asymmetry with occlusal cant which was treated by bimaxillary distraction osteogenesis. Simultaneous mandibular and maxillary distraction corrected the facial asymmetry without disturbing the pre-existing compensated dental occlusion, and so there was no need for prolonged and difficult orthodontic treatment.
Giant cemento-ossifying fibroma—A case report and review of literature  [PDF]
U. S. Pal, Nimisha Singh, Shailendra Kumar, R. K. Singh, Laxman R. Malkunje
Open Journal of Stomatology (OJST) , 2012, DOI: 10.4236/ojst.2012.24062
Abstract: Cemento-ossifying fibroma (COF) of maxilla is comparatively rare lesion of the maxillofacial region. There is often a misdiagnosis in the category of fibroosseous lesions, owing to an overlap of clinical, histological and radiographic features amongst the separate entities. We present a case of giant maxillary COF causing extensive disfiguration of the face, along with extensive review of the clinico-pathologic and treatment aspects of the fibro-osseous lesions.
Abundance and distribution of gaseous ammonia and particulate ammonium at Delhi, India

Biogeosciences (BG) & Discussions (BGD) , 2012,
Abstract: This study reports abundance and distribution of gaseous NH3 and particulate NH4+ at Delhi. Gaseous NH3 and particulate NH4+ concentrations were measured during pre-monsoon, monsoon and post-monsoon seasons of the years 2010 and 2011. Average concentrations of gaseous NH3 during pre-monsoon, monsoon and post-monsoon seasons were recorded as 26.4, 33.2 and 32.5 μg m 3, respectively. Gaseous NH3 concentrations were the highest during monsoon, thought to be due to decay and decomposition of plants and other biogenic material under wet conditions, leading to increased NH3 emission. The results showed that particulate NH4+ was always lower than the gaseous NH3 during all the seasons. The concentrations of particulate NH4+ were recorded as 11.6, 22.9 and 8.5 μg m 3 during pre-monsoon, monsoon and post-monsoon seasons, respectively. The percent fraction of particulate NH4+ was noticed to be highest during the monsoon season, which is attributed to increased humidity levels favouring partitioning into the aerosol phase. On an average, 33.3% of total N-NHx was present as particulate NH4+. Higher concentrations of NH3 noticed during night time may be due to stable atmospheric conditions. The study highlighted that, as compared with rural sites, urban sites showed higher concentrations of gaseous NH3 in India, which may be due to higher population density, human activities and poor sanitation arrangements.

Correlation of DNA Ploidy with Progression of Cervical Cancer
M. Singh,S. Mehrotra,N. Kalra,U. Singh,Y. Shukla
Journal of Cancer Epidemiology , 2008, DOI: 10.1155/2008/298495
Abstract: The majority of squamous cell carcinomas of cervix are preceded by visible changes in the cervix, most often detected by cervical smear. As cervical cancer is preceded by long precancerous stages, identification of the high-risk population through detection of DNA ploidy may be of importance in effective management of this disease. Here we attempted to correlate aneuploid DNA patterns and their influence on biological behavior of flow-cytometry analysis of DNA ploidy which was carried out in cytologically diagnosed cases of mild (79), moderate (36), and severe (12) dysplasia, as well as “atypical squamous cells of unknown significance (ASCUS)” (57) along with controls (69), in order to understand its importance in malignant progression of disease. Cytologically diagnosed dysplasias, which were employed for DNA ploidy studies, 39 mild, 28 moderate, and 11 severe dysplasia cases were found to be aneuploid. Out of the 69 control subjects, 6 cases showed aneuploidy pattern and the rest 63 subjects were diploid. An aneuploidy pattern was observed in 8 out of 57 cases of cytologically evaluated ASCUS. The results of the followup studies showed that aberrant DNA content reliably predicts the occurrence of squamous cell carcinoma in cervical smear. Flow cytometric analysis of DNA ploidy may provide a strategic diagnostic tool for early detection of carcinoma cervix. Therefore, it is a concept of an HPV screening with reflex cytology in combination with DNA flow cytometry to detect progressive lesions with the greatest possible sensitivity and specificity.
Inversion of 2-D DC resistivity data using rapid optimization and minimal complexity neural network
U. K. Singh, R. K. Tiwari,S. B. Singh
Nonlinear Processes in Geophysics (NPG) , 2010,
Abstract: The backpropagation (BP) artificial neural network (ANN) technique of optimization based on steepest descent algorithm is known to be inept for its poor performance and does not ensure global convergence. Nonlinear and complex DC resistivity data require efficient ANN model and more intensive optimization procedures for better results and interpretations. Improvements in the computational ANN modeling process are described with the goals of enhancing the optimization process and reducing ANN model complexity. Well-established optimization methods, such as Radial basis algorithm (RBA) and Levenberg-Marquardt algorithms (LMA) have frequently been used to deal with complexity and nonlinearity in such complex geophysical records. We examined here the efficiency of trained LMA and RB networks by using 2-D synthetic resistivity data and then finally applied to the actual field vertical electrical resistivity sounding (VES) data collected from the Puga Valley, Jammu and Kashmir, India. The resulting ANN reconstruction resistivity results are compared with the result of existing inversion approaches, which are in good agreement. The depths and resistivity structures obtained by the ANN methods also correlate well with the known drilling results and geologic boundaries. The application of the above ANN algorithms proves to be robust and could be used for fast estimation of resistive structures for other complex earth model also.
