Abstract
With increasing longevity of lupus patients, peripheral vascular disease (PVD) has become an important cause of morbidity. With no systematic study of PVD in systemic lupus erythematosus (SLE), this study was undertaken to define the frequency and spectrum of PVD in SLE and factors affecting such an occurrence. All medium-sized peripheral arteries of bilateral upper and lower extremities were studied in 50 SLE patients using Doppler ultrasonography. PVD was defined clinically as one or more of intermittent claudication, absent/unequal pulses, gangrene or ischemic ulcers and sub-clinically as asymptomatic patients with Doppler abnormalities, with ≥50% reduction in diameter considered hemodynamically significant. Mean (SD) age of the patients was 31.6 (10.1) years. Forty-one percent were hypertensive. Dyslipidemia was found in 62%. Fifteen (30%) had Raynaud's phenomenon. Fourteen (28%) patients had PVD, of whom three had positive markers for antiphospholipid antibody (aPL) and six were asymptomatic. Ischemic ulcers were seen in eight (16%), gangrene in three (6%), femoral artery plaques in two (4%), stenosis in four (8%) and intermittent claudication in none. Dyslipidemia was found to independently affect occurrence of PVD (OR = 5.37, [95% CI 1.05—27.5], P = 0.05). The causes of PVD overlap significantly and further studies are needed to ascertain the relative contribution of each. Lupus (2007) 16, 720—723.

Abstract
Co-infection due to Mycobacterium tuberculosis, Cryptococcus and Naegleria fowleri has not been reported till now in literature, to the best of our knowledge. Here we report a curious case of co-infection of the central nervous system due to these three pathogens in an apparently immune-competent, HIV negative boy. The 15 year old boy was a diagnosed case of tubercular meningitis and was on anti-tubercular and anti-epileptic treatment. However, two months later he presented again in the emergency department with sudden loss of consciousness. His CSF showed presence of capsulated budding yeast cells (suggestive of Cryptococcus) and flagellated parasites (resembling the flagellated stage of Naegleria fowleri). CSF was also positive for Cryptococcal antigens by Latex Agglutination test. The boy was HIV negative and apparently immuno-competent. He was subsequently put on amphotericin B therapy for six weeks. Repeat microscopy, done towards the end of amphotericin B course, showed clearing of CSF. However, the patient's condition improved only slightly, owing to neurological damage caused by the pathogens as suggested by brain CT and MRI scans. Thus infection caused by the members of three different kingdoms in an apparently immunocompetent boy highlights the importance of thinking beyond the ordinary causative pathogens, and actively searching for rarer etiologies to ensure timely intervention; especially in nonresponsive cases.

Abstract
This study adopted an integrated 'source-to-receptor' assessment paradigm in order to determine the effects of emissions from passenger transport on urban air quality and human health in the megacity, Delhi. The emission modeling was carried out for the base year 2007 and three alternate (ALT) policy scenarios along with a business as usual (BAU) scenario for the year 2021. An Activity-Structure-Emission Factor (ASF) framework was adapted for emission modeling, followed by a grid-wise air quality assessment using AERMOD and a health impact assessment using an epidemiological approach. It was observed that a 2021-ALT-III scenario resulted in a maximum concentration reduction of ~24%, ~42% and ~58% for carbon monoxide (CO), nitrogen dioxide (NO2) and particulate matter (PM), respectively, compared to a 2021-BAU scenario. Further, it results in significant reductions in respiratory and cardiovascular mortality, morbidity and Disability Adjusted Life Years (DALY) by 41% and 58% on exposure to PM2.5 and NO2 concentrations when compared to the 2021-BAU scenario, respectively. In other words, a mix of proposed policy interventions namely the full-phased introduction of the Integrated Mass Transit System, fixed bus speed, stringent vehicle emission norms and a hike in parking fees for private vehicles would help in strengthening the capability of passenger transport to cater to a growing transport demand with a minimum health burden in the Delhi region. Further, the study estimated that the transport of goods would be responsible for ~5.5% additional VKT in the 2021-BAU scenario; however, it will contribute ~49% and ~55% additional NO2 and PM2.5 concentrations, respectively, in the Delhi region. Implementation of diesel particulate filters for goods vehicles in the 2021-ALT-IV-O scenario would help in the reduction of ~87% of PM2.5 concentration, compared to the 2021-BAU scenario; translating into a gain of 1267 and 505 DALY per million people from exposure to PM2.5 and NO2 concentrations, respectively. These findings suggest that significant health benefits are possible if goods transport is also included while designing strategies and policies in order to improve the overall urban air quality and minimize health impacts in city areas.

Abstract
Background The purpose of this open-label study was to correlate the auscultation findings of ZargisCardioscan™ with the echocardiographic findings in our patient population who were referred for echocardiography so as to investigate and ensure the validity of this technology before instituting its applicability in community health events among rural Indian population. Materials and Methods This was a double blinded prospective correlation study in outpatients presenting for echocardiography. Methods: One hundred patients, who had presented for echocardiography at Cardiology Center of an academic university hospital in rural India, were enrolled in this double blinded prospective correlation study. Principal investigator who is a community medicine physician performed the auscultation of patients’ hearts in sitting position. Subsequently, the ZargisCardioscan™ software was used to analyze the heart sounds auscultated by the 3M™ Littmann® Model 3200 stethoscope. Thereafter, the scheduled echocardiography for which the patient had presented to hospital was performed by co-investigator cardiologist who was blinded to the results obtained by the ZargisCardioscan™.Finally, all these data were statistically analyzed by blinded investigator for the presence of correlation between the two modalities. Results The most important finding was the high 90s negative predictive values when the stethoscope-software combination was used for auscultation and analysis of heart murmurs. Additionally, presence of isolated systolic murmurs had higher incidence of appreciable significant valvular lesions and presence of isolated diastolic murmurs primarily had underlying minimal-mild regurgitant valvular lesion, if any. The Bland-Altman Plot confirmed good correlation between stethoscope-echocardiography findings. Conclusion Stethoscope-software combination, 3M™ Littmann® Model 3200 and ZargisCardioscan™, accurately predicts the absence of valvular heart disease on echocardiography.DOI: http://dx.doi.org/10.3126/nje.v4i3.10665 Nepal Journal of Epidemiology 2014; 4(3): 363-369

Abstract
Patients with orocutaneous fistulas suffer from discomfort in terms of facial esthetics, food spill over and lack of psychological confidence to present them socially. Prosthetic camouflaging of facial defects and use of silicone maxillofacial material are the alternatives to the surgical retreatment. Silicone elastomers provide more options to clinician for customization of the facial prosthesis which is simple, esthetically good when coupled with bio magnets for retention.

Abstract
Background: To identify the socio-demographic differences between a sample of women who present for first-trimester and second-trimester abortion. Aim: To determine whether women presenting late (in the second trimester) for abortion differ socio-demographically from those presenting early (in the first trimester). Materials and Methods: Data over 4 years for women presenting for second-trimester abortion were collected from the records of Family Planning Clinic at a public tertiary level teaching hospital in India. Eighty-four cases were analysed. The case presenting for first-trimester abortion after each second-trimester abortion was included for comparison. Information was gathered concerning age, parity, educational background, employment status, educational background of the husband, family expenditure and religion. Data were statistically analysed and significance determined using logistic regression analysis. Results: Second-trimester abortions represented 2% (84/4254) of all abortions in the study period. More women of higher age (P = 0.03) and parity (P = 0.02) and higher educational status (P = 0.04) presented for second-trimester abortion as compared to first-trimester abortion. The occupational status of the woman, husband's educational background, monthly family expenditure per person and religion did not significantly influence the time of presentation for abortion. Conclusion: Second-trimester abortions are associated with both increasing age and parity and higher education. This group of educated, older and multiparous women should be one of those targeted for counseling to reduce the risks associated with second trimester abortion.

Abstract
Pregnancy is often associated with ocular changes which may be more commonly transient but occasionally, permanent. The ocular effects of pregnancy may be physiological or pathological or may be modifications of pre-existing conditions. Physiological changes include increased pigmentation around the cheeks, ptosis, changes in cornea and refractive status,decreased intraocular pressure. These usually resolve post partum. Pre-existing diseases such as Graves disease, Retinitis pigmentosa, optic neuritis, should be monitored due to their remission or relapses in pregnancy. There may be worsening of Diabetic retinopathy, and Central serous chorio-retinopathy with increased risk of Retinal detachment. Conditions like Glaucoma and Non infectious uveal inflammatory disorders may even improve transiently. Pre-eclampsia and eclampsia could result in hypertensive retinopathy, exudative retinal detachment and cortical blindness. Neuro-ophthalmological disorders such as venous sinus thrombosis, benign intracranial hypertension, pituitary adenoma, meningioma and optic neuritis should be kept in mind as differential diagnosis in pregnant women presenting with visual acuity loss, visual field loss, persistent headaches or oculomotor palsies. Use of ophthalmic drugs can affect fetal health during pregnancy.
