BACKGROUND Seroprevalence of IgG antibodies against SARS-CoV-2 is an important tool to estimate the true extent of infection in a population. However, seroprevalence studies have been scarce in South East Asia including India, which, as of now, carries the third largest burden of confirmed cases in the world. The present study aimed to estimate the seroprevalence of anti-SARS-CoV-2 IgG antibody among hospitalized patients at one of the largest government hospital in India OBJECTIVE The primary objective of this study is to estimate the seroprevalence of SARS-CoV-2 antibody among patients admitted to the Medicine ward and ICU METHODS This cross-sectional study, conducted at a tertiary care hospital in North India, recruited consecutive patients who were negative for SARS-CoV-2 by RT-PCR or CB-NAAT. Anti-SARS-CoV-2 IgG antibody levels targeting recombinant spike receptor-binding domain (RBD) protein of SARS CoV-2 were estimated in serum sample by the ELISA method RESULTS A total of 212 hospitalized patients were recruited in the study with mean age (±SD) of 41.2 (±15.4) years and 55% male population. Positive serology against SARS CoV-2 was detected in 19.8%patients(95% CI 14.7-25.8). Residency in Delhi conferred a higher frequency of seropositivity 26.5% (95% CI 19.3-34.7) as compared to that of other states 8% (95% CI 3.0-16.4) with p-value 0.001. No particular age groups or socio-economic strata showed a higher proportion of seropositivity CONCLUSIONS Around, one-fifth of hospitalized patients, who were not diagnosed with COVID-19 before, demonstrated seropositivity against SARS-CoV-2. While there was no significant difference in the different age groups and socio-economic classes; residence in Delhi was associated with increased risk (relative risk of 3.62, 95% CI 1.59-8.21)

Introduction: There is a general consensus that results of hypospadias repair surgery, done on children, seem to have a better outcome when compared to the adults. Hypospadias cases in adults can present as primary or with complications resulting from an attempted repair. Aim: To assess any difference in outcome of surgeries done among the adolescent and adult population and to evaluate the use of a Tunica Vaginalis (TV) second layer barrier flap in preventing complications such as urethrocutaneous fistula. Materials and Methods: This was a single centre retrospective observational assessment of the adolescent and adult hypospadias surgeries conducted at a Tertiary Care Hospital from January 2016 to July 2019. The assessment was based on the presentation, site of hypospadias meatus, previous surgery and development of any complications or recurrence. Routine surgeries as per the hospital protocol were done in these patients. Follow-up was done for the next 12 months. For data analysis tables, columns and pie charts were used. Fisher’s-exact test was used to find the association and calculate the p-value with the help of SPSS 21.0 software. Results: Total 28 patients were assessed, of which 17 patients were adolescents (mean age 14.6±1.66 years) and 11 (mean age 22.7±3.51 years) were adult. There was no significant (p-value 0.581) difference in the final outcome of hypospadias repair surgery between the adolescent and adult population. Use of TV interposition barrier flap prevented development of complications. Urethrocutaneous fistula was the most common form of complication noted in both the groups overall rate of complication was 14.2%. Conclusion: When hypospadias repair in adolescents and adults is done in a systematic and meticulous fashion, the outcome was satisfactory and there was no significant difference in outcome among the two age groups. Use of TV flap as a second layer interposition can improve the outcome in such patients.

Background: The proportion of antimicrobial-resistant Enterobacterales that are causative pathogens for community-acquired acute pyelonephritis (CA-APN) has been increasing. We examined the effect of antimicrobial resistance on medical costs in CA-APN. Methods: A single-center retrospective cohort study was conducted at a tertiary-care hospital in Korea between January 2018 to December 2019. All hospitalized patients aged ≥19 years who were diagnosed with CA-APN were recruited, and those with Enterobacterales as a causative pathogen were included. Comparisons between CA-APN caused by extended-spectrum β-lactamase (ESBL)–producing pathogens (ESBL+ group) and those by non–ESBL-producing organisms (ESBL– group) as well as CA-APN caused by ciprofloxacin-resistant pathogens (CIP-R group) and those by ciprofloxacin-sensitive pathogens (CIP-S group) were performed. Log-linear regression was performed to determine the risk factors for medical costs. Results: In total, 241 patients were included in this study. Of these, 75 (31.1%) had an ESBL-producing pathogen and 87 (36.1%) had a ciprofloxacin-resistant pathogen. The overall medical costs were significantly higher in the ESBL+ group compared with the ESBL− group (US$3,730.18 vs US$3,119.32) P <0.001) as well as in CIP-R group compared with CIP-S group (3,730.18 USD vs. 3,119.32 USD, P =0.005). In addition, length of stay was longer in ESBL+ group compared with ESBL-group (11 vs. 8 days, P <0.001) as well as in CIP-R group compared with CIP-S group (11 vs. 8 days, P <0.001). There were no significant difference in the proportion of clinical failure between ESBL+ and ESBL- groups; CIP-R and CIP-S groups. Based on the log-linear regression model, the costs associated with ESBL-producing Enterobacterales as the causative pathogen would be, on average, 27% higher or US$1,211 higher than its counterpart (P = .026). By the same token, a patient who is a year older would incur US$23 higher cost (P = .040). Having any structural problem in urinary tract would incur US$1,231 higher cost (P = .015). A unit increase in Pitt score would incur US$767 USD higher cost (P < 0.001) higher cost, all other things constant. Conclusions: Medical costs for hospitalized patients with CA-APN are increased by the existence of ESBL-producing Enterobacterales but not by the existence of ciprofloxacin-resistant Enterobacterales.Funding: NoDisclosures: None

Background: Ischemic heart disease is the most common cause for complete heart block (CHB) and sudden death. Heartblocks may occur as complications of acute myocardial infarction (AMI) and are associated with increased mortality. The aim of thisstudy is to determine the frequency of complete heart block (CHB) in acute myocardial infarction at a tertiary care hospital. Place andduration: This study was conducted in Cardiology Department of Liaquat University of Medical and Health Sciences from 1st August2009 to 31st January 2010. Study Design: Cross sectional and descriptive study. Materials and Methods: ST segment elevation equal toor more than 1mm (0.1mv) in two of these leads II, III and aVF. Rise in serum creatinine kinase level (CPK Level) more than twice thenormal value along with CK-MB fraction more than 6% of CPK value. Patients with history of chest pain, shortness of breath, nausea,vomiting and unconsciousness were enrolled in the study. The cardiac enzymes tropinin T was also performed at bed side by venousblood sample. Results: Total of 87 patients were included, prevalence of heart blocks was 27.58%. Anterior wall MI was in 50(57.5%)patients. Of these, 13(54.2%) had complete heart block. Inferior wall MI was in 37(42.5%) cases, of these, 11(45.8%) were found withcomplete heart block. There was no significant difference between anterior wall MI and inferior wall MI with complete heart block (P value> 0.05). Mortality was 2.3% with anterior wall MI. Conclusions: Development of complete heart blocks has important prognosticsignificance. Complete heart block was frequent complication of myocardial infarction.

ABSTRACT Background: Alarming rise of vancomycin-resistant enterococci (VRE) is a global cause of concern. Several factors have been held responsible for such rise, of which antibiotic usage is a prominent one. Objectives: This study was undertaken to determine the intestinal VRE colonization rate amongst hospitalized patients in relation to use of various antibiotics in the Intensive Care Unit (ICU) of a tertiary care university hospital, India. Materials and Methods: Stool samples were collected weekly from all the patients in the adult ICU for a period of 6 months and processed for isolation and phenotypic and genotypic characterization of VRE isolates. Patient and treatment details were noted and cases (those with VRE in stool) and controls (those without VRE in stool) were compared statistically. Further, a multivariate analysis was done to identify those antibiotics as independent risk factors for VRE colonization. Results: VRE colonization was found in 34.56% (28/81) of the patients studied, with the majority 75% (21/28) carrying the vanA gene. The cases had significantly more (P < 0.05) duration of hospital stay and antibiotic exposure. Intake of metronidazole, vancomycin, and piperacillin-tazobactam were identified as significant risk factors both in univariate and multivariate analysis. Conclusion: A potential reservoir of VRE was thus revealed even in low VRE prevalence setting. Based on this high colonization status, restriction of empirical antibiotic use, reviewing of the ongoing antibiotic policy, and active VRE surveillance as an integral part of infection control strategy were suggested.

Background: Dengue is one of the important causes of acute febrile illnesses in India. Dengue can be a fatal disease, however there are no reliable markers which can predict mortality among these patients.Methods: A prospective cross sectional study was done in patients who were admitted to a tertiary care hospital with features of dengue fever. A total of 364 patients with IgM dengue serology positive were included in the study. Relevant clinical and laboratory parameters were collected from all patients. Association between clinico-laboratory parameters with mortality was studied using appropriate statistical methods.Results: Among the 364 patients recruited in this study, 14 (3.85%) patients died. Mortality among patients with age group 18-40 years was 2.04%, in patients aged above 40 years was 7.56%. Mortality among patients with hypotension was 42.42% (14 out of 33), bleeding manifestations was 15.38% (8/52), platelets <20,000/mm3 was 10.41% (10/96), ALT >200 was 13.04% (6/46), AST>200 was 12.34% (10/81), prolonged prothrombin time was 60%(12/20), renal failure was 28%(14/50), encephalopathy was 31.57% (6/19), multi organ dysfunction syndrome(MODS) was 43.33% (13/30), acute respiratory distress syndrome (ARDS) was 45.45% (5/11), pleural effusion was 7.5% (6/80).Conclusions: The overall mortality in the present study was 3.85%. Following variables were associated with increased risk of death among the dengue patients: Age >40 years, presence of hypotension, platelets <20000 cells/mm3, ALT>200U/L, AST>200U/L, prolonged prothrombin time, presence of renal failure, encephalopathy, MODS, ARDS and bleeding tendency (p value <0.05). Early identification of factors associated with mortality can help to make appropriate decision on care required.

Abstract A retrospective chart review was carried out in children (neonates to 18 years) who underwent acute surgical abdominal exploration during 2012-2016 at the Aga Khan University Hospital, Karachi, to evaluate the post-operative surgical site infection rates in emergency paediatric abdominal surgery. Incidence of surgical site infection (SSI) was estimated. P-value was calculated, chi-square and non-parametric tests were performed by comparing pre-surgical and post-surgical procedure pathogen occurrence and pre-procedure wound status. Pathogen occurrence related to time-trend of 98 paediatric patients who underwent emergency abdominal surgery was plotted. Of the 94 who were discharged in stable condition, it was found that there was no significant difference between pre- and post-surgical pathogens. Escherichia coli (n=10) was found to be the most common pathogen. Contaminated wounds were associated with higher SSI (p=0.036, OR 1.95 95% CI 0.7-5.4). Continuous...

OBJECTIVE: To compare the final facial nerve outcomes between middle cranial fossa (MCF) vs translabyrinthine (TL) resection of size-matched vestibular schwannomas. STUDY DESIGN AND SETTING: Retrospective case review at a tertiary care hospital. All patients who underwent resection utilizing either MCF or TL approaches with tumors 18 mm or smaller and complete data were included in the analysis. One hundred twenty-four patients were identified meeting the above criteria, with sixty-three in the translabyrinthine group and sixty-one in the middle fossa group. One-week-postoperative and final facial nerve examinations were compared in the two surgical groups. Patients were separately analyzed in subgroups: tumors smaller than 10 mm and those that were between 10 and 18 mm. RESULTS: The tumor size range for the MCF group was 3-18 mm while it was 4-18 mm for the TL group. No statistically significant difference was found in facial nerve outcomes between the two surgical groups, at the first postoperative visit week and at last follow-up. CONCLUSION: Facial nerve outcomes are similar using TL and MCF approaches for resection of vestibular schwannomas up to 18 mm in size. SIGNIFICANCE: Patients undergoing the MCF approach for hearing preservation can be counseled that there is no increased risk of permanent facial nerve weakness, compared to the TL approach.

Introduction/Objective. After the introduction of the national program of fertility treatment, increased frequency of multiple pregnancies was noted. The literature has shown controversies regarding the higher risk of morbidity and mortality of the preterm newborns from multiple pregnancies. Methods. Preterm singletons, twins and triplets born within a two-year study period were included in the analysis. Data about preterm twins were extracted first. For each pair of twins, two singletons of the same gestation age were chosen. The set of the examinees was completed by including the triplets born during the same period. The short-term outcomes were compared between these three groups. Results. A total of 210 preterm infants were included in the study, out of which 84 singletons, 84 twins and 42 triplets. Statistical analysis showed significant difference between the three groups regarding type of conception (p < 0.0001), mode of delivery (p < 0.001) and birth weight (p = 0.005). Short-term mortality and morbidity (neonatal death, the need for intubation at birth, respiratory support, surfactant therapy, and intracranial hemorrhage) were significantly increased in triplets comparing to singletons and twins. Conclusion. Preterm triplets have an increased risk for adverse short-term outcomes comparing to singletons and twins of the similar gestation age in our study sample.

Background : The aim of this study were assess the susceptible pregnant women for vaccine preventable infection like rubella, mumps, measles and varicella viruses. Infection of mothers with these viruses during pregnancy can be serious. They can cause congenital infections, miscarriage, stillbirth and death of fetuses. Material and Method : This study is cross sectional. To determine the presence of IgG antibodies for rubella, mumps, measles and varicella viruses, blood samples were collected, stored at -700 c. Serum was separated for detection of IgG antibodies for these viruses by using enzyme linked immunosorbant assay. Results : Of 277 samples evaluated for IgG antibodies. Susceptibility Of pregnant women for rubella, mumps measles and varicella viruses were 7.6%, 17.6%,7.2% and 19.5% respectively. Susceptibility rates for rubella and mumps were higher in rural population as compares to urban while for varicella urban population was more susceptible, but it was not statistically signicant. No correlation could be observed in susceptibility to different to different viruses and their education status and age of patients, but youngest age group was most susceptible to varicella and oldest group to rubella. Primigravida were more susceptible to rubella and varicella while multigravida were more susceptible to mumps and measles. Conclusion : Majority of the pregnant women had protective levels of IgG antibody although susceptibility to rubella, mumps measles and varicella were low. Intensication of MMRV immunization of all females of child-bearing age is advocated.
