Abstract
BACKGROUND The assessment of hidradenitis suppurativa (HS) severity requires detailed, and error-prone lesion counts. This proof-of-concept study aimed to automatically classify HS disease severity using machine learning of clinical smartphone images. METHODS 777 ambient-light and size-controlled images were used to build a class-balanced synthetic dataset (n = 7675). Convolutional neural networks (CNN) were used for automated severity classification (scale 0-3), and to assess disease-dynamics. International Hidradenitis Suppurativa Severity Score System (IHS4) served as reference. A U-NET algorithm was implemented for automated localization of diseased skin. RESULTS CNNs were able to distinguish no/mild from moderate/severe disease with an overall prediction accuracy of 78% [receiver operating curve (AUC) 0.85]. Correct IHS4 classification was achieved with an overall accuracy of 72% (AUC 0.84-0.89). In addition, disease dynamics using IHS4 numerical values aligned with CNN outputs (NRMSE 0.262). The UNET algorithm localized lesions with a pixel accuracy of 88.1% and test loss of 0.42. LIMITATIONS Limitations in assessing tattooed and hairy skin. Limited number of patients with dark skin colour and Hurley I. CONCLUSION CNNs were able to distinguish no/mild from moderate/severe disease, classify disease severity over time, and automatically identify diseased skin areas and the skin phototype. This study breaks new grounds for fast, reliable, reproducible and easy-to-use HS severity assessments using clinical images.

Abstract
To understand the influence of family 3 Carbohydrate Binding Module (hereafter CBM3), single (GH5 cellulase; CelB, CelBΔCBM), bi-chimeric [GH26 endo-mannanase (ManB-1601) and GH11 endo-xylanase (XynB); ManB-XynB [1], ManB-XynB-CBM] and tri-chimeric [ManB-XynB-CelB [1], ManB-XynB-CelBΔCBM] enzyme variants (fused or deleted of CBM) were produced and purified to homogeneity. CBM3 did not alter the pH and temperature optima of bi- and tri-chimeric enzymes but improved the pH and temperature stability of ManB in CBM variants of bi-/tri-chimeric enzymes. Truncation of CBM in CelB shifted the pH optimum and increased the melting temperature (Tm 65 ℃). CBM3 improved both substrate affinity (Km) and catalytic efficiency (kcat/Km) of fused enzymes in tri-chimera and CelB but only Km for bi-chimera. Far-UV CD of CelB and bi- and tri-chimeric enzymes suggested that CBM3 improved the α-helical content and compactness in the native state but did not prevent disintegration of secondary structural contents at acidic pH. Steady-state fluorescence studies suggested that under acidic conditions CBM3 prevented the exposure of hydrophobic patches in bi-chimeric protein but could not avert the opening up of chimeric enzyme structure. Aqueous enzyme assisted treatment of mature coconut kernel using single, bi- and tri-chimeric enzymes led to cracks, peeling and fracturing of the matrix and improved the oil yield by up to 22%.

Abstract
Intraoperative bleeding poses a substantial challenge, particularly in neuro-spine surgeries leading to complications such as hematomas, infections, and hemodynamic instability. Despite their proven efficacy, use of topical hemostatic agents (THAs) lacks comprehensive published literature and guidelines particularly in the Indian setting. The present study provides the first-ever Indian expert panel recommendations for effective adjunct THA use in different intraoperative bleeding sites and situations in neuro-spine surgeries. A comprehensive approach, encompassing a literature review, followed by experience sharing in a meeting using a survey helped integrate expert opinions in the form of practical algorithms to guide THA selection. Our survey results revealed a strong inclination towards specific THAs, flowable gelatin + thrombin being choice of THA for difficult to access and problematic bleeding situations during tumor removal/resection, transsphenoidal hypophysectomy and skull-based procedures. Both oxidized regenerated cellulose (ORC)/Fibrillar and flowable gelatin + thrombin were recommended for continuous oozing. ORC/Fibrillar was preferred for arteriovenous and cavernous malformations. This expert-panel guidance on THA use aims to optimize hemostat use practices and improve surgical outcomes in neuro-spine surgery.

Abstract
BACKGROUND Antioxidant present in sperm cells protects them from oxidative damage. However, sperm are more susceptible to peroxidative damages due to the loss of these enzymes during cryopreservation and their survival and fertility may be compromised. Insulin like growth factor-1 (IGF-1) has an antioxidant effect and could maintain sperm motility. OBJECTIVE To improve seminal parameters, mitochondrial membrane potential (MMP), oxidative status and DNA integrity of buck semen after freeze-thawing by fortification of goat semen diluent with various concentrations of IGF-1. MATERIALS AND METHODS Fifty ejaculates were collected and were extended with tris- citric acid- fructose diluent with 10% egg yolk and 6% glycerol with sperm concentrations of 1×108 mL-1. Post-cryopreserved sperm were assessed for motility and a range of other functional parameters. RESULTS In post-thaw semen sperm motility, live sperm count, acrosome integrity, hypo-osmotic swelling positive spermatozoa, malondialdehyde (MDA), protein carbonyl content (PCC), TUNEL positive sperm differed significantly (P<0.05) with the various concentrations of IGF-1 used. Sperm functional parameters post-thawing were significantly (P<0.05) better in 250 ng/mL IGF-1. IGF-1 protects against lipid peroxidation by lowering MDA and PCC production, thus reducing the harmful effect of reactive oxygen species. The kidding percentage using the artificial insemination technique was significantly higher ( i.e., 40%) in the group supplemented with 250 ng/mL of IGF-1 than in the non-supplemented group (i.e., 30%). CONCLUSION IGF-1 may be used to improve post-thaw semen quality and fertility as measured by actual kidding rate. Doi.org/10.54680/fr23610110312.

Abstract
Single parent adoption (SPA) is a relatively new construct worldwide and in India. The Ministry of Women and Child Development, Government of India, has laid down criteria for adoption in general and SPA in particular, in conjunction with the Juvenile Justice Act (Care and Protection of Children), 2015. There is scant literature on this topic of SPA, more so in India, that looks into the various psychological nuances of SPA from a mental health professional's (MHP) perspective. This review paper aims to assess SPA from the perspective of a MHP that will focus on its various legal nuances as well as the psychological connotations attached to it. For this, a search strategy was employed that included a thorough literature search from two databases (PubMed and Google Scholar) with relevant keywords related to the topic. The various legal issues pertaining to SPA in the current scenario, the psychological issues and challenges faced by single parents, the behavioral outcomes of adoptees who are adopted by single parents, and ways to deal with the various obstacles of SPA are discussed.

Abstract
Ophthalmic literature reveals vague and rare references to Horner syndrome on a hereditary basis. We present a case series of mother and son with Horner syndrome, which was confirmed pharmacologically. They noticed symptoms on the same side at a similar age and no serious pathology was found.Retrospective case review of notes:Case 1: An 11-year-old male presented with 6 week history of anisocoria, mild right ptosis, no heterochromia and no history of trauma or previous surgeries. The anisocoria was more noticeable in the dark, Horner syndrome was confirmed with apraclonidine test.Case 2: Mother of case 1, 50-year-old female diagnosed with right Horner syndrome at the age of 14 in Austria. The presenting features were anisocoria, a lack of sweating on the right side of her face. Diagnosis was reconfirmed pharmacologically.Case 1 was referred to paediatrics for a systemic examination which was normal. He was investigated with urinary catecholamines, MRI head and CT neck and thorax which were all normal. Case 2 was investigated in the past with a normal CT head.Horner syndrome results in the interruption of the oculo-sympathetic pathway and can indicate serious pathology in the head, chest or neck. Our cases demonstrate that familial presentation could indicate an idiopathic aetiology as it is unlikely to have pathological Horner syndrome in two first degree relatives.Our case series highlights the importance of eliciting a family history of Horner syndrome and examining the family members. Positive family history can reassure patients while awaiting results of investigations.

Abstract
Frozen shoulder, also known as adhesive capsulitis, is a condition featured by stiffness and pain in shoulder joint. In this report, we present a case of 58 years old diabetic male patient with the history of coronary artery bypass grafting (CABG) 06 months back. He presented with persistent right shoulder pain for 05 months. Clinical examinations reveal restriction of the right shoulder joint movement in all directions and wasting of the right supraspinatus, infraspinatus and trapezius muscles. Both active and passive range of motions was restricted with painful right shoulder joint. Pain free abduction range was about 40 degrees in right shoulder. Plain X-ray of right shoulder joint and other relevant investigations show normal findings. Considering the clinical and laboratory findings decision was taken to treat the patient with exercise, pain killer and ultrasound therapy which were found to be optimistic.

Abstract
BACKGROUND Defensins are antimicrobial peptides and uniformly spans the entire sperm surface and is not exclusive to a specific domain. Goat β-defensin-1 helps in initiation of motility and capacitation of sperm. OBJECTIVE To know the status of β-defensin-1 in blood, semen and its effect on post thaw fertility gene expression in Indian goat breeds. MATERIALS AND METHODS Semen was extended and divided for estimation of β-defensin-1 and cryopreserved having different concentrations of β-defensin-1. RESULTS Bet defensin-1 concentration (pg/mL) in neat semen, sperm pellet and seminal plasma was significantly higher (P< 0.05) in goat breed Barbari followed by Jamunapari and Jakhrana. β-defensing-1 was also high in Jakhrana blood followed by Barbari and Jamunapari. The post thaw motility, live sperm, acrosome intactness and hypo osmotic swelled sperms were significantly higher (P< 0.05) with 10 ng/mL β-defensin in the semen dilutor. CONCLUSION Beta defensin (10 ng/mL) in semen dilutor may be used as immuno-modulator to get better post thaw quality suitable for artificial insemination.

Abstract
Background: Vesical paraganglioma is rare and accounts for <0.1% of all urinary bladder tumors. They are mostly functional because of secretion of catecholamines and clinical presentation may mimic like a hyperfunctioning adrenal pheochromocytoma. They are easily misdiagnosed as urothelial malignancy and adequate perioperative attention is not provided. Case presentation: We hereby report a case of 55-year-old Indian lady with silent vesical paraganglioma at anatomically difficult location of bladder neck managed with robot-assisted excision of mass and bladder preservation. Conclusion: Surgery is the mainstay of the treatment that requires total excision of mass. However, minimally invasive bladder-preserving approach should be always kept as an option, if feasible. Robot assistance can help in bladder preservation even in difficult anatomic locations.

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
Shewanella putrefaciens rarely causes human infection. These are mostly found in environment and food stuffs. Shewanella are often found in mixed culture. It has been implicated in cellulitis, otitis media, and septicemia. It may be found in respiratory tract, urine, feces, and pleural fluid. There is no definite guideline for therapeutic option. In general, these are susceptible to various antimicrobial agents but are often resistant to penicillin and cephalothin. We report a rare case of bacteremia by S. putrefaciens in a patient of head injury with polytrauma after a road traffic accident.

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
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
Burkholderia cepacia has been recognized as a group of highly virulent organisms known as Burkholderia cepacia complex (Bcc). Bcc are ubiquitous in nature and most commonly found in moist environment, on plant roots and soil. Because of its high intrinsic antibiotic resistance, Bcc is a major cause of morbidity and mortality in hospitalized patients. It is reported most commonly in immunocompromised patients especially in patients with cystic fibrosis. Here, we report a rare case report of bacteraemia by Burkholderia cepacia in an immunocompetent male, who presented with fever and Multiple Organ Dysfunction Syndrome (MODS). Burkholderia cepacia was isolated from his blood culture, which he acquired from his work place. He was treated successfully and discharged after negative blood culture.

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
Sphingomonas paucimobilis , a yellow-pigmented, aerobic, glucose nonfermenting, Gram-negative bacilli is a rare cause of human infection. It was first discovered as an infective agent in humans in 1977 and named Pseudomonas paucimobilis. It was renamed as S. paucimobilis in 1990 in accordance with phylogenetic data. S. paucimobilis is an aerobic bacterium found in soil and water; it is a rare cause of healthcare associated infections. S. paucimobilis can cause infections in healthy as well as immunocompromised individuals. At first, its colony looks like Gram-positive bacilli colony, so by mistake it is discarded as contaminants. S. paucimobilis is an emerging pathogen and it should not be discarded as contaminants. Here, we report a case of S. paucimobilis bacteremia in a neonate who presented with respiratory distress.

Abstract
IntroductionOver the last eight decades, general hospital psychiatric units (GHPUs) have become important mental health service set-ups in India. This period has seen a large number of radical changes in the Indian society. In this background, it is important to know if it had any effects on the patients attending the GHPUs.MethodologyA total of five hundred subjects, attending a GHPU were recruited prospectively for the study. The subjects were assessed using a semi-structured proforma. A comparison was made with similar studies conducted in GHPU settings over the last 5 decades.ResultsNeurotic, stress related and somatoform disorders was the commonest diagnostic group (33%) followed by psychotic disorders (17%) and mood disorders (15%). The finding is broadly similar to the studies done at different times in the last 5 decades. However, there were lesser number of patients with mental retardation, organic brain syndrome and seizure disorder.ConclusionThe study highlights the strengths of GHPU set-ups like inter-speciality referrals, fewer stigmas, patients travelling from far off places to seek treatment and involvement of family in the care of mentally ill.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Multiplex reverse-transcription polymerase chain reaction (mRT-PCR) assay is a sensitive and rapid method for the detection and serotyping of foot and mouth disease virus (FMDV). However, the method has not been used to its full potential, because of factors such as cost, a lack of infrastructure and the complexity of the reaction mixture. This study was undertaken to optimise and validate a thermostable, lyophilised, ready-to-use mRT-PCR kit for the rapid detection of FMDV in field laboratories in India. Trehalose, PEG-8000 and glycerol were evaluated for stabilisation of the PCR mixture at ambient temperatures. The lyophilised mRT-PCR kit was validated and found robust enough for use in field-level laboratories. The PCR reaction mixture in the ready-to-use kit has low complexity, so chances of cross-contamination during the preparation of the mixture are limited, but may easily be monitored by using lyophilised internal positive and negative controls. In addition, the requirement to maintain live FMDV isolates as internal positive controls at field-level regional laboratories is eliminated.

Abstract
BACKGROUND Meningomyelocele is a defect of the spinal cord, vertebrae, and the overlying skin and is the most common form of open spinal dysraphism. Rapid closure of the back defect in the early postnatal period is mandatory to reduce the frequency of infection-related complications of the central nervous system. Majority of the cases present with small defects, which can be closed primarily, with or without subcutaneous dissection. However, direct closure is not possible in 25% of the cases. Different types of local flaps (skin or muscle flaps) are widely used for covering the skin defects; and with varying results. PATIENTS AND METHODS A prospective nonrandomized study was conducted in the department of pediatric surgery at a tertiary hospital, from September 2007 to October 2011. Overall 35 patients with large meningomyelocele defects that could not be closed primarily were included in the study. All patients were treated using subcutaneous tissue based pedicle flap with bilateral V-Y advancement. RESULTS There were 27 neonates, 7 infants, and 1 child, with a male:female ratio of 1.19:1. There were 3 thoracolumbar, 14 lumbar, 14 lumbosacral, 3 sacral, and 1 multiple meningomyelocele defects with an average size of 8.5 cm (range 6.5-11 cm). Average intraoperative blood loss was 8 mL (range 6-10.5 mL). Average operative time which included flap reconstruction time, after closure of dura, was 38.6 min. Total seven patients had wound complications viz. fat necrosis (n = 2), flap necrosis (n = 2), hematoma (n = 1), cerebrospinal fluid leak followed by wound dehiscence (n = 1), wound infection which led to meningitis (n = 1). Average healing time for flap repair was 7.52 days. Overall 80% (n = 28) of the patients had good flap texture and contour with satisfactory cosmesis. CONCLUSION Closure of large meningomyelocele wound defects with subcutaneous based pedicle flap with bilateral V-Y advancement is an effective technique. The main advantages of this technique are its simplicity, short operative time, good tolerance, early healing, and good cosmetic outcome with an excellent flap texture and contour match with minimal complications.
