Abstract
Objective: To highlight the unusual complication of subcapsular renal hematoma (SRH) after a seemingly simple ureteroscopic lithotripsy (URSL), to try and identify the predisposing factors that lead to this complication, and steps that can be taken to further decrease the incidence of this rare but potential life-threatening complication. Methods: We highlight two cases of obstructed ureteral stones with upstream hydronephrosis who presented with colicky pain. Both underwent URSL with 8F/9.8F semirigid ureteroscope and were found to have postprocedure SRH. Results: Both our patients were managed conservatively with culture-directed intravenous antibiotics. One patient needed intervention in the form of aspiration of the hematoma. Follow-up ultrasound revealed complete resolution of the hematoma in both the cases and are doing fine on follow-up. Conclusion: Various risk factors have been identified, which predispose an individual to this complication and all endourologists must take certain precautionary measures such as decreased operative time and perfusion pressures, treating urinary tract infections and preoperative optimization of hypertension, diabetes, and chronic kidney disease (CKD) to further decrease the incidence of SRH. Management is conservative in majority of cases with percutaneous drainage and antibiotics, with surgery being reserved for hemodynamically unstable patients.

Abstract
Sources of airborne particulates (PM10) were investigated in two contrasting sites over central Indo-Gangetic Plain (IGP), one representing a rural background (Mirzapur) and another as an urban pollution hotspot (Varanasi). Very high PM10 concentration was noted both in Varanasi (178 ± 105 μgm-3; N:435) and Mirzapur (131 ± 56 μgm-3; N:169) with 72% and 62% of monitoring days exceeded the national air quality standard, respectively. Particulate-bound elements contribute significant proportion of PM10 mass (15%-18%), with highest contribution from Ca (7%-10%) and Fe (2%-3%). Besides, presence of Zn (1%-3%), K (1%-2%) and Na (1%-2%) was also noted. Water-soluble ionic species contributed 15%-19% of particulate mass, primarily by the secondary inorganic aerosols (SIA). Among the SIA, sulphate (5%-7%) and nitrate (4%) were prominent, contributing 59%-62% of the total ionic load, especially in winter. Particulate-bound metallic species and ions were selectively used as signatory molecules and source apportionment of PM10 was done by multivariate factor analysis. UNMIX was able to extract particulate sources in both the locations and crustal resuspensions (dust/-soil) were identified as the dominant source contributing 57%-63% of PM10 mass. Secondary aerosols were the second important source (17%-23%), followed by emissions from biomass/-refuse burning (10-19%). Transport of airborne particulates from upper IGP by prevailing westerly were identified as the important contributor of particulates, especially during high particulate loading days. Health risks associated to particulate-bound toxic metal exposure were also assessed. Non-carcinogenic health risk was within the permissible limit while there is possibility of elevated risk for PM10-bound Cr and Cd, if adequate control measures are not in place.

Abstract
INTRODUCTION To analyse the results of Cauda Equina Syndrome (CES) operated by Percutaneous Transforaminal Endoscopic Lumbar Discectomy (PTELD). MATERIAL AND METHODS The study is a retrospective series of 15 patients operated by PTELD. Bladder dysfunction was classified as incomplete CES (CESI) and complete CES retention (CESR). Bladder / motor recovery rate and its timing, Oswestry Disability Index (ODI), Visual Analogue Score (VAS), patient satisfaction index, and sexual dysfunction were used to measure the outcome objectively. Additionally, in CESR patients, post-void residual (PVR) urine was measured by sonography. Complications and technical problems were noted. RESULTS There were ten patients of CESI and five patients of CESR. The average follow-up was 20.33(12.05) months. Bladder symptoms recovery was 100%, and motor recovery was 80%. VAS for back pain recovered to 0.53(0.52) from 8(2.39). VAS for leg pain recovered to 0.13(0.35) from 9.20(1.32). ODI improved to 6.07(2.85) from 77.52(13.20). The time to the recovery of bladder function was 1.47(1.55) days. All CESR patient's abnormal PVR urine was normalised at five weeks post-operative. No complications were reported. However, five technical executional problems occurred. CONCLUSION PTELD can be considered for CES treatment due to its substantial and quick recovery advantages. However, more evidence support is needed to make it a practice recommendation.

Abstract
This study was aimed to compare the long-term outcomes and survival rate among mitral valve replacement using thoracotomy and standard median sternotomy in a single surgeon's practice. Total 250 patients were evaluated; Group I (n=65) patients had anterolateral thoracotomy and Group II (n=185) had standard median sternotomy for valve replacement. Mean age was 25.1±5 years in Group I and 41.8±10.5 years in Group II. Female was predominant in Group I. Total operative time and bypass time was statistically significant in Group I (235.5±25.8 minutes; 84.2±12.75 minutes) in contrast to Group II (203.8±15.5 minutes; 71.5±10.5 minutes). Incision scar was not visible in females in Group I but full incision scar was visible in Group II. Post-operative ICU stay duration was significant high in Group II. Though, wound infection incidence was 0% in Group I; however, 9.73% patient had wound infection in Group II. Only 1.62% patient developed unstable sternum in Group II. Most of the patients from both study group were in regular follow up and 1-year mortality rate was 4.62% and 5.94% in Group I and Group II respectively. Mitral valve replacement through a right anterolateral thoracotomy is easy and safe to perform; while getting maximum benefits for the patients. Besides satisfactory cosmetic outcome especially in female, this approach provides better exposure to mitral apparatus even in patients with small left atrium, cost effectiveness, less duration of hospital stays and absence of the risk for unstable sternum.

Abstract
This study aimed to evaluate myocardial protective effect of isoflurane and propofol as a fast tract anesthesia in off pump coronary artery bypass graft surgery by measuring postoperative cardiac enzyme Troponin-I, and liver enzyme. The study was conducted on 260 patients scheduled to undergo elective off pump coronary artery bypass graft surgery. Patients were randomly allocated to receive either isoflurane or propofol anesthesia and was aimed to extubated within 6 hours. Troponin-I levels were measured preoperatively, at arrival in postoperative intensive care unit, at 12, 24, 48, 72 hours and 4 weeks following surgery. Liver function was also assessed and compared between preoperative and postoperative values. There is no difference in Troponin-I levels between the two studies groups at observed pre and post-operative time intervals. Fast tract anesthesia using isoflurane and propofol provides same myocardial protection during and after OPCABG and overall outcome was excellent.

Abstract
Abstract
Background
Antitachycardia pacing (ATP) for monomorphic VT (MVT) reduces painful defibrillation shocks. Most ICD-treated ventricular arrhythmias are MVT, suggesting an opportunity for improved ATP to decrease shocks. We report on a new algorithm (Yee, Circ AE 2017) that uses electrophysiologic (EP) first-principles to design ATP sequences in real-time. Heart-rate history is used to design the first ATP sequence, and failed ATP post-pacing interval is used to design later sequences.
Purpose
The purpose of this modeling study was to understand how this new ATP algorithm would perform in a head-to-head comparison with traditional burst ATP. Modeling allows direct comparison of the two algorithms in identical, realistic, patient-derived cardiac arrythmias.
Methods
Patient-specific late gadolinium enhanced MRI and EP data were used to build an adjudicated cohort of realistic numerical heart models with varied EP, infarct, border zone. Publicly available EP modeling software CARPentry was used to calculate sustained reentrant VT initiated with the programmed electrical stimulation used to induce VT clinically. The VTs were physician-adjudicated to validate models. Burst ATP was 3 sequences of 8 pulses at 88% of VT cycle length, each decremented by 10ms. The new ATP was limited to 3 automatically designed sequences.
Results
Three hundred unique VT scenarios were generated from 6 human hearts with multiple VT circuits, 5 electrophysiologic states, and 10 pacing locations. Burst ATP terminated 168/300 VTs (56%) and accelerated 2.7%. The new ATP terminated 234/300 VTs (78%) with the same acceleration. The two dominant ATP failure mechanisms were identified as 1) insufficient prematurity to close the excitable gap, and 2) failure to reach the critical isthmus of the VT circuit. For these mechanisms, the new ATP algorithm reduce failures from 64 to 28 (44% reduction) without increasing acceleration.
Conclusion
The new automated ATP algorithm successfully adapted ATP sequences for VT episodes that burst ATP failed to terminate. The new ATP was successful even with complex scar geometries and electrophysiology heterogeneity as seen in the real world.

Abstract
The aim of this retrospective cohort study was to evaluate the occurrence of the maternal and fetal outcome during pregnancy and immediately after delivery in women with prosthetic heart valve, especially with oral anticoagulants therapy that must be weighed against the risk of intracardiac thrombosis. This study was undertaken at Department of Cardiac surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from January 2012 to December 2017. A total of 82 pregnancies with heart valve prosthesis were evaluated in two groups: Group I (n=58) includes pregnancy with mechanical heart valve, while Group II (n=24) includes pregnancy with bioprosthetic valve. The mean age of patients was 25.7±2.5 years and 24.9±5.5 years in Group I and Group II respectively. Approximately 70% pregnancies ended in healthy live births, however about 75% of study population developed maternal complications in Group I, which is significantly higher than Group II. First trimester spontaneous miscarriage was statistically significant between two groups (p value <0.005). Mean birth weight and mean APGAR score was found normal in both study group. Majority of the patients were found in good health status during and after pregnancy. Proper antenatal care and early risk stratification are the fundamental measures to improve the maternal and fetal outcome in a patient with prosthetic heart valve.

Abstract
Propofol causes pain on intravenous injection in 28 to 90% of patients. A number of techniques have been tried to minimize propofol-induced pain, with variable results. In a randomized, double-blind, placebo-controlled trial, we compared the efficacy of ephedrine 30 μg/kg pretreatment to lignocaine 40 mg for prevention of propofol-induced pain. Ninety-three adult patients, ASA 1 and 2, undergoing elective laparoscopic cholecystectomy were randomly assigned to three groups of 31 each. Group 1 received normal saline, group 2 received lignocaine 2% (40 mg) and group 3 received 30 μg/kg ephedrine. All pretreatment drugs were made up to 2 ml. Pain at the time of propofol injection was assessed on a four-point scale: 0=no pain, 1=mild pain, 2=moderate pain, and 3=severe pain. Twenty-seven patients (87%) of ephedrine pretreatment patients had pain during intravenous injection of propofol as compared to 24 (77%) in the normal saline group. In the lignocaine group, propofol-induced pain was observed in only 13 (42%) when compared with other study groups (P<0.05). Pretreatment with ephedrine 30 μg/kg did not attenuate pain associated with intravenous injection of propofol, nor did it improve haemodynamic stability during induction. However, pretreatment with 2% lignocaine (40 mg) was effective in attenuating propofol-associated pain.

Abstract
Syphilis is notorious and a great imitator of all diseases. It is a chronic bacterial infection, caused by the sexually transmitted spirochete, Treponema pallidum. Though it has drastically reduced in prevalence, its recent resurgence (especially with HIV disease) is worrying. Without treatment, the disease can progress over years through a series of clinical stages and lead to irreversible neurological or cardiovascular complications. The disease may occur in any organ, including the testis, and is commonly mistaken for malignancy. We report a case of scrotal abscess consequent on epididymo-orchitis, confirmed by histopathological examination to be syphilitic in origin, in an immunocompromised HIV-positive patient.

Abstract
This study compared the therapeutic efficacy of levofloxacin, ornidazole and alpha tocopherol combination and prostaglandin F2α (PGF2α) in longstanding cases of endometritis and evaluated their impact on Interleukin-6 (IL-6) and Interleukin-10 (IL-10) transcript level in peripheral blood leukocytes. Eighteen endometritic crossbred Jersey cows were randomly allotted to three groups (six in each) viz. Group I (levofloxacin combo treatment I/U), group II (PGF2α treatment I/M), group III (no treatment, control), and group IV (six non-endometritic healthy cyclic) was taken for comparison study. The clinical efficacy was assessed by haematological study (TLC: Total leukocyte count; DC: Differential count), polymorphonuclear leukocytes (PMN) count in uterine cytology and relative mRNA expression of IL-6 and IL-10 in peripheral blood leukocytes before and after treatment with respect to conception rate following single and second inseminations. Group I and II registered significant increase in TLC and neutrophil count. PMN cytology was increased two and three fold in group I and II, respectively. The IL-6 transcript level was increased by 2.5 and 4.6 fold while that of IL-10 increased by 3.7 and 5.2 fold in group I and II, respectively. Conception rate across group I to IV following single insemination was found to be 66.67%, 50%, 16.67%, and 83.33% and their corresponding values following second insemination were 66.67%, 83.33%, 16.67%, and 83.33%, respectively. Thus, the administration of levofloxacin combo and PGF2α might have better conception rate following first and second insemination, respectively. Our study also reveals that PGF2α could register better clearance of bacteria through stronger PMN cell and cytokine activity in post-treatment period.

Abstract
Foot-and-mouth disease (FMD) is an important transboundary disease with substantial economic impacts. Although between-herd transmission of the disease has been well studied, studies focusing on within-herd transmission using farm-level outbreak data are rare. The aim of this study was to estimate parameters associated with within-herd transmission, host physiological factors and FMD virus (FMDV) persistence using data collected from an outbreak that occurred at a large, organized dairy farm in India. Of 1,836 regularly vaccinated, adult dairy cattle, 222 had clinical signs of FMD over a 39-day period. Assuming homogenous mixing, a frequency-dependent compartmental model of disease transmission was built. The transmission coefficient and basic reproductive number were estimated to be between 16.2-18.4 and 67-88, respectively. Non-pregnant animals were more likely to manifest clinical signs of FMD as compared to pregnant cattle. Based on oropharyngeal fluid (probang) sampling and FMDV-specific RT-PCR, four of 36 longitudinally sampled animals (14%) were persistently infected carriers 10.5 months post-outbreak. There was no statistical difference between subclinical and clinically infected animals in the duration of the carrier state. However, prevalence of NSP-ELISA antibodies differed significantly between subclinical and clinically infected animals 12 months after the outbreak with 83% seroprevalence amongst clinically infected cattle compared to 69% of subclinical animals. This study further elucidates within-herd FMD transmission dynamics during the acute-phase and characterizes duration of FMDV persistence and seroprevalence of FMD under natural conditions in an endemic setting.

Abstract
Background: Oral health is an integral part of general health. Poor oral health can have adverse effect on general health hence a good oral health is very essential, which in turn is achieved by good oral hygiene. Even though, the concept of good oral hygiene evolved 5000 years back, it is only in the beginning of 19th century it gained more importance. (1) Dental caries and periodontal disease are the most commonly occurring diseases affecting mankind. Dental plaque is a very important factor in the causation of both the diseases. (2) Aims & Objectives: To evaluate efficacy of four different types of toothbrushes, with difference in duration of brushing along with different bristle hardness in removal of microbial plaque. Material & Methods: In a randomized controlled trial, four groups with 40 subjects used manual toothbrushes with either hard, medium, soft and ultra-soft bristles. On baseline examination, clinical parameter plaque index (Sillness & Loe, 1964) was recorded. Selected subjects were refrained from all kinds of oral hygiene measures for 24 hrs before clinical appointment. On the day of clinical appointment scores of pre and post brushing were recorded in each patient when brushing time was set for 1 minute and same procedure was repeated after a wash off period of 3 days and similar recordings were made with brushing time of 11/2minute. Primary outcome was measured with differences in the plaque index (Sillness & Loe, 1964) compared to baseline. Results: Significant reduction in mean value of plaque score was observed on comparing pre-brushing and post-brushing data in all the subjects irrespective of bristle hardness in both 1 minute and 11/2 minute groups. On increasing time duration from 1 minute to 11/2 minute intergroup comparison revealed that significant correlation exist in mean plaque score reduction in subjects using medium bristle brush, soft bristle brush, ultra-soft bristle brush. However, no significant reduction in plaque score was observed on increasing duration from 1 minute to 11/2 minute in subjects using hard bristle brush. Conclusion: Manual toothbrushes with hard bristles better remove plaque, but may also cause more soft tissue trauma compared to brushes with softer bristles.

Abstract
The goal of this study was to characterize the properties and duration of the foot-and-mouth disease (FMD) carrier state and associated serological responses subsequent to vaccination and naturally occurring infection at two farms in northern India. Despite previous vaccination of cattle in these herds, clinical signs of FMD occurred in October 2013 within a subset of animals at the farms containing juvenile-yearling heifers and steers (Farm A) and adult dairy cattle (Farm B). Subsequent to the outbreak, FMD virus (FMDV) asymptomatic carriers were identified in both herds by seroreactivity to FMDV non-structural proteins and detection of FMDV genomic RNA in oropharyngeal fluid. Carriers' seroreactivity and FMDV genome detection status were subsequently monitored monthly for 23 months. The mean extinction time of the carrier state was 13.1 ± 0.2 months, with extinction having occurred significantly faster amongst adult dairy cattle at Farm B compared to younger animals at Farm A. The rate of decrease in the proportion of carrier animals was calculated to be 0.07 per month. Seroprevalence against FMDV non-structural proteins decreased over the course of the study period, but was found to increase transiently following repeated vaccinations. These data provide novel insights into viral and host factors associated with the FMDV carrier state under natural conditions. The findings reported herein may be relevant to field veterinarians and governmental regulatory entities engaged in FMD response and control measures.

Abstract
OBJECTIVE The primary objective was to evaluate the effect of statin therapy/lipid lowering therapy (LLT) on lipid profile, in adults presenting with first acute coronary event. METHODS AND MATERIAL A multicentre, observational, prospective cohort study of lipid profiles pre- and post-statin therapy/LLT, among adult patients with confirmed diagnosis of first acute coronary event. The primary outcome measures were low-density lipoprotein cholesterol (LDL-C) in mg/dl, high-density lipoprotein cholesterol (HDL-C) in mg/dl and triglycerides (TG) in mg/dl at baseline and end of study (EOS, 12 weeks [mean: 13.5 weeks]). RESULTS Totally 474 patients completed the study. Number of patients with any LDL-C abnormality (LDL-C [all; LDL was abnormal, either alone or along with other lipid parameter(s)]) decreased from 118 (24.9%) to 27 (5.7%), and for LDL-C (only; only the LDL was abnormal), from 46 (9.7%) to 13 (2.7%), both from baseline to EOS. Of 118 patients with high LDL-C (all) at baseline, 91 (77.1%) had reduction in LDL-C to <100mg/dl, of which 54 (45.8%) had LDL-C <70mg/dl at EOS. The patients with LDL-C fraction abnormalities decreased, while HDL-C abnormalities increased at EOS from baseline. No major difference was observed at baseline and EOS in levels of TG (all [TG was abnormal, either alone or along with other lipid parameter(s)]) and TG (only [only the TG was abnormal]). Six (1.3%) had seven serious adverse events. CONCLUSIONS Though statin therapy is effective in lowering LDL-C, there still remains residual dyslipidemia, which probably should be tackled with therapeutic and non-therapeutic options.

Abstract
Concomitant occurrence of lung carcinoma and an atrial myxoma is rare. We are reporting such a case, a 55 year old male, farmer, smoker for 30 years was under evaluation for his recent episode of stroke with hemiparesis during which an echocardiography showed presence of a left atrial myxoma and chest x-ray showed a lesion in the midzone of right lung. Fine needle aspiration cytology (FNAC) from enlarged right supraclavicular lymphnode revealed metastatic adenocarcinoma. Patient was referred to a tertiary cancer care hospital thereafter.
