Robust foreground modelling to segment and detect multiple moving objects in videos

Last decade has witnessed an ever increasing number of video surveillance installations due to the rise of security concerns worldwide. With this comes the need for video analysis for fraud detection, crime investigation, traffic monitoring to name a few. For any kind of video analysis application, detection of moving objects in videos is a fundamental step. In this paper, an efficient foreground modelling method to segment multiple moving objects is implemented. Proposed method significantly reduces noise thereby accurately segmenting region of interest under dynamic conditions while handling occlusion to a large extent. Extensive performance analysis shows that the proposed method was found to give far better results when compared to the de facto standard as well as relatively new approaches used for moving object detection

Replantation of Nine Fingers in a Patient: A case report

Amputation of multiple fingers of both hands is a rare and serious injury. We report a case of a 41-year-old male patient who presented to Khoula Hospital, Muscat, Oman, in 2015 with the amputation of nine fingers due to a workplace injury. With two teams working in tandem, all the amputated fingers were re-attached. A total of seven fingers survived and the patient regained reasonable functionality of his hands. To the best of the authors’ knowledge, this is the first case of several finger amputations in Oman.Keywords: Fingers; Traumatic Amputation; Crush Injuries; Replantation; Case Report; Oman

Enhancing the insulation capability of a vaccine carrier box: An engineering approach

Being thermosensitive, Vaccines need storage at specific temperatures of 2-8 \ub0C, and Vaccine Cold chain Carriers are the most widely utilized instruments to carry out rural vaccination drives in Low-income hot climate countries. Several developed designs for the carrier have reported superior performance, but their actual penetration into rural community medicine is limited due to reasons of cost and utility. Thus, the scope for improvement in the design is significant and it is also pertinent to quantify the effect of design features on the performance. Taking shared features possessed by such superior designs, the work presents the impact of geometry, vertically stacked vaccine tray assembly and usage of Phase Change Materials(PCM), on the final passive cooler assembly. A fabricated New Design with given features is cross-compared and analysed with a Market(Original) Design of the same scale and storage capacity. Analysis performed takes a scientific inclination towards Engineering and Insulation aspects of the Vaccine Box. It uses Conjugate Heat Transfer model(CFD simulations), Geometry analysis, experimentally derived Insulation R-values and Temperature monitoring to accomplish this. Secondly, the work presents a systematic design approach to improve upon the conventional design, PCM selection is made using DSC(Differential Scanning Calorimetry) testing, and Material of Construction(MOC) selection is made using Ashby plots based on the results of the simulations. Overall the Fabricated New Design gives an improvement of ≈16% in R-value and ≈17% improvement in the retention time of the specific temperature range, over the conventional (Original) Design

Peak expiratory flow rate nomogram in relation to anthropometric determinants of South Indian school children

Background: The predictive normal value of peak expiratory flow rate (PEFR), used in monitoring of healthy andasthmatic children, is correlated with height, but it may vary with other anthropometric measurements and ethnicdifferences. Purpose: To study the correlation of PEFR with age, sex, body mass index (BMI), chest circumference(CC), and MUAC and to formulate PEFR nomograms in relation to these anthropometric variables in a ruralschool going children of age group 6-12 years in southern India. Methods: A descriptive cross-sectional studywas conducted in 2000 children consist of 993 boys and 1007 girls who fulfilled the selection criteria from eightrandomly selected government schools from a rural area. PEFR was measured age wise using Mini-Wright peakflow meter and the highest among the three values was taken. PEFR nomograms were formulated, and its correlationwith BMI, height, weight, CC, and MUAC were estimated using linear regression analysis. Results: PEFR hasstrong (p < 0.001) positive correlation with age, height, weight, MUAC, and CC, but it has poor correlation withBMI (p = 0.985) which showed flat regression line with narrow 95% confidence limits. Conclusion: In this study,PEFR has nonsignificant correlation with BMI but has strong positive correlation with other anthropometricmeasurements. This underlines the need of a local reference nomogram as anthropometric measurements affect thePEFR reference values

Importance of general examination in diagnosis: a rare case report of a family affected with Albright’s hereditary osteodystrophy

Albright’s hereditary osteodystrophy (AHO) is rare constellation of signs associated with pseudohypoparathyroidism (PHP) associated with genomic imprinting in GNAS1 gene. We described a case report of a patient with AHO phenotype with pseudopseudohypoparathyroidism (PPHP) with associated chronic liver disease and its complications and her pedigree analysis

An unusual presentation of rectal atresia with rectal duplication cyst in a neonate: A case report

A 10 days old male baby brought with abdominal distension and cystic swelling in the left buttock. Radiological investigationssuggested para-rectal abscess or rectal duplication cyst. Patient underwent transverse loop colostomy and later definitivesurgery by posterior sagittal approach. Intra-operative findings were suggestive of small atretic rectal segment with duplicationcyst of the rectum. To the best of our knowledge, neonatal rectal atresia with rectal duplication cyst has not been reported inEnglish literature

HEREDITORY GINGIVAL FIBROMATOSIS IN A 7-YEAR-OLD GIRL: A CASE REPORT

ABSTRACTThis paper presents a case of hereditary gingival fibromatosis, a rarely reported disorder and addresses the complex nature of oral diagnosis,treatment and long-term case management in the hereditary form of recurrent gingival fibromatosis. Case management is discussed in relation toa 7-year-old girl who presented with recurrent, progressive gingival enlargement requiring consecutive periodontal treatment. The initial course oftreatment included 4-quadrant gingivectomy with excisional bevel incisions, followed by microscopic examination of the gingivectomy specimenswhich supported the clinical diagnosis. 1 year later, recurrence of the condition was observed in all quadrants. It is recommended that patients withthis condition be monitored closely after gingivectomy so that the treatment requirements of localized areas can be addressed as needed.Keywords: Heredity, Genome, Phenotype, Chromosome, Autosomal inheritance

CARDIOVASCULAR COMPLICATIONS IN CHRONIC OBSTRUCTIVE PULMONARY DISEASE WITH REFERENCE TO 2D ECHOCARDIOGRAPHY FINDINGS

Background: Chronic Obstructive Pulmonary Disease (COPD) is the disease of lungs primarily but also produces significant systemic consequences like pulmonary arterial hypertension (PAH). COPD results in chronic hypoxemia consequently which causes PAH. PAH then leads to corpulmonale and right ventricular failure late in the course of the COPD. 2D echocardiography is probably the best technique to measure tricuspid regurgitation and pulmonary arterial pressure non-invasively. Material and Methods: 50 cases above the age of 18 years admitted with signs and symptoms of COPD in our hospital over a period of two years were taken. Diagnosis of COPD was made on basis of history, signs and symptoms, supported by spirometry, electrocardiographic, echocardiographic and radiological data. 2D echocardiography was performed on these patients to detect the presence of tricuspid regurgitation, PAH, right ventricular hypertrophy, right ventricular dilatation and right ventricular failure. Results: Emphysema and chronic bronchitis was present in 38% and 62% respectively. Echocardiographic evidence of cor-pulmonale and pulmonary hypertension was found in 70% of the patients. Conclusions: Echocardiography is more sensitive than electrocardiography in detecting PAH and right ventricular dysfunction in COPD
