ABSTRACT
Transesophageal echocardiography (TEE) offers an invaluable, non-invasive avenue for diagnosing and managing various cardiac conditions, including atrial fibrillation (AF). As the most common cardiac arrhythmia, AF affects millions and can lead to severe complications. Cardioversion, a procedure to restore the heart's normal rhythm, is frequently conducted on AF patients resistant to medication. Due to inconclusive data, TEE's utility prior to cardioversion in AF patients remains ambiguous. Understanding TEE's potential benefits and limitations in this population could significantly influence clinical practice. This review aims to scrutinize the current literature on the use of TEE before cardioversion in AF patients. The principal objective is to understand TEE's potential benefits and limitations comprehensively. The study seeks to offer a clear understanding and practical recommendations for clinical practice, thereby improving the management of AF patients before cardioversion using TEE. A literature search of databases was conducted using the keywords "Atrial Fibrillation," "Cardioversion" and "Transesophageal echocardiography," resulting in 640 articles. These were narrowed to 103 following title and abstract reviews. After applying exclusion and inclusion criteria with a quality assessment, 20 papers were included: seven retrospective studies, 12 prospective observational studies, and one randomized controlled trial (RCT). Stroke risk associated with direct-current cardioversion (DCC) potentially results from post-cardioversion atrial stunning. Thromboembolic events occur post cardioversion, with or without prior atrial thrombus or cardioversion complications. Generally, cardiac thrombus localizes in the left atrial appendage (LAA), a clear contraindication to cardioversion. Atrial sludge without LAA thrombus in TEE is a relative contraindication. TEE before electrical cardioversion (ECV) in anticoagulated AF individuals is uncommon. In AF patients planned for cardioversion, contrast enhancement facilitates thrombus exclusion in TEE images, reducing embolic events. Left atrial thrombus (LAT) frequently occurs in AF patients, necessitating TEE examination. Despite the increased use of pre-cardioversion TEE, thromboembolic events persist. Notably, patients with post-DCC thromboembolic events had no LA thrombus or LAA sludge. The use of TEE-guided DCC has grown due to its ability to detect atrial thrombi pre-cardioversion, aiding risk stratification. Thrombus in the left atrium also signals an elevated risk of future thromboembolic events in AF patients. While atrial stunning post cardioversion detected by TEE is a significant risk factor for future thromboembolic events, further evidence is required. Therapeutic anticoagulation is essential during and post cardioversion, even if no atrial thrombus is detected. Current data recommends cardioversion guided by TEE, particularly in outpatient settings.
ABSTRACT
Aim: The aim of this study was to evaluate the role of histopathological and histomorphometric features in oesophageal biopsy of patients presenting with symptoms of Gastroesophageal Reflux Disease (GERD). Material and Methods: Present study included 42 patients and 12 controls. Complete clinical evaluation followed by endoscopic examination of the patients was done and multipleoesophageal biopsies were taken. Biopsies were processed routinely and stained with Hematoxylin and Eosin and examined for any changes related to GERD. Morphometric assessment was done by using Leitz optical micrometer. The histological scoring was done based on the parameters: basal cell hyperplasia, stromal papillae elongation, cells with irregular nuclear contour (CINC), eosinophilic infiltrate, gastric and intestinal metaplasia. A numerical score was assigned to each parameter and sum of these scores represented the total score. Statistics: The statistical analysis was done using graph pad prism, Medcalc software and Windows MS office. P value and mean standard deviation (SD) was calculated. Results: The endoscopic findings of all the controls and 83.33% of patients were normal. Only 16.67% of patients had reflux associated changes of varying grades on endoscopy. Oesophageal biopsy of all patients had changes related to GERD on histology. Immunohistochemistry confirmed that cells with irregular nuclear contour were T- lymphocytes. The mean (SD) histological scoring of control and patients were 1.75 (0.62) and 5.66 (1.31) respectively. The difference was considered to be statistically significant (P < 0.001). Thus, it was suggested that a cut-off of histological score > 3 can be used to indicate GERD. Conclusion: Patients with gastroesophageal reflux symptoms can have normal endoscopic findings but can be diagnosed on the basis of histological changes in the squamous epithelium. Scoring of the histopathological parameters along with the cut-off value can give a definitive diagnosis of GERD.

Portal hypertensive bleeding is a major complication of portal hypertension (PHT) with high morbidity and mortality. A lot of advances have been made in our understanding of screening, risk stratification, and management strategies for portal hypertensive bleeding including acute variceal bleeding leading to improved overall outcomes in patients with PHT. A number of guidelines on variceal bleeding have been published by various societies in the past few years. The Indian Society of Gastroenterology (ISG) Task Force on Upper Gastrointestinal Bleeding (UGIB) felt that it was necessary to bring out a standard practice guidance document for the use of Indian health care providers especially physicians, gastroenterologists, and hepatologists. For this purpose, an expert group meeting was convened by the ISG Task Force to deliberate on this matter and write a consensus guidance document for Indian practice. The delegates including gastroenterologists, hepatologists, radiologists, and surgeons from different parts of the country participated in the consensus development meeting at Coorg in 2018. A core group was constituted which reviewed all published literature on portal hypertensive UGIB with special reference to the Indian scenario and prepared unambiguous statements on different aspects for voting and consensus in the whole group. This consensus was produced through a modified Delphi process and reflects our current understanding and recommendations for the diagnosis and management of portal hypertensive UGIB in Indians. Intended for use by the health care providers especially gastroenterologists and hepatologists, these consensus statements provide an evidence-based approach to risk stratification, diagnosis, and management of patients with portal hypertensive bleeding.

Stroke is considered to be one of the most important causes of death worldwide. Global ischemia causes widespread brain injury and infarctions in various regions of the brain. Oxidative stress can be considered an important factor in the development of tissue damage, which is caused because of arterial occlusion with subsequent reperfusion. Kapikacchu or Mucuna pruriens, commonly known as velvet bean, is well known for its aphrodisiac activities. It is also used in the treatment of snakebites, depressive neurosis, and Parkinson's disease. Although this plant has different pharmacological actions, its neuroprotective activity has received minimal attention. Thus, this study was carried out with the aim of evaluating the neuroprotective action of M. pruriens in bilateral carotid artery occlusion-induced global cerebral ischemia in Wistar rats. The carotid arteries of both sides were occluded for 30 min and reperfused to induce global cerebral ischemia. The methanolic plant extract was administered to the study animals for 10 days. The brains of the Wistar rats were isolated by decapitation and observed for histopathological and biochemical changes. Cerebral ischemia resulted in significant neurological damage in the brains of the rats that were not treated by M. pruriens. The group subjected to treatment by the M. pruriens extract showed significant protection against brain damage compared with the negative control group, which indicates the therapeutic potential of this plant in ischemia.

The human stomach is colonized by diverse bacterial species. The presence of non-Helicobacter pylori bacteria in urease-positive biopsies of individuals has been reported. Bacteria belonging to the Ochrobactrum genus have been documented in the human gastric niche. The co-occurrence of Ochrobactrum spp. with H. pylori was previously reported in an antral biopsy of a non-ulcer dyspeptic (NUD) subject from Northern India. There is no information on the genetic diversity of Ochrobactrum spp. isolated from the gastric niche in the stomach. We aimed to study the species distribution and diversity of Ochrobactrum spp. with and without H. pylori in urease-positive biopsies across three different geographical regions in India. Sixty-two Ochrobactrum isolates recovered from patients with an upper gastric disorder (n=218) were subjected to molecular identification and multilocus sequence typing. H. pylori DNA was found in the majority of biopsies, which had a variable degree of Ochrobactrum spp present. Interestingly, some of the urease-positive biopsies only had Ochrobactrum without any H. pylori DNA. Based on phylogenetic analysis, the Ochrobactrum isolates were distributed into the O. intermedium, O. anthropi and O. oryzae groups. This indicates there are multiple species in the gastric niche irrespective of the presence or absence of H. pylori. Antibiotyping based on colistin and polymyxin B could differentiate between O. intermedium and O. anthropi without revealing the resistance-driven diversity. Considering the prevalence of multiple Ochrobactrum spp. in the human gastric niche, it is important to evaluate the commensal and/or pathogenic nature of non-H. pylori bacteria with respect to their geographical distribution, lifestyle and nutrition needs.

Non-alcoholic fatty liver disease (NAFLD) is closely associated with metabolic syndrome. Prevalence of metabolic risk factors including diabetes mellitus, obesity, etc. is rapidly increasing in India putting this population at risk for NAFLD. Patients with NAFLD are at increased risk for liver-related morbidity and mortality and also cardiovascular disease risk and increased incidence of diabetes mellitus on long-term follow-up. Management of patients with NAFLD may require a multi-disciplinary approach involving not only the hepatologists but also the internists, cardiologists, and endocrinologists. This position paper which is a combined effort of the Indian National Association for Study of the Liver (INASL), Endocrine Society of India (ESI), Indian College of Cardiology (ICC) and the Indian Society of Gastroenterology (ISG) defines the spectrum of NAFLD and the association of NAFLD with insulin resistance and metabolic syndrome besides suggesting preferred approaches for the diagnosis and management of patients with NAFLD in the Indian context.
ABSTRACT
OBJECTIVES: Herpes simplex virus-2 (HSV-2) and syphilis are associated with increased risk of HIV, highlighting the importance of understanding their transmission dynamics. In India, most studies of HSV-2 and syphilis incidence are in high-risk populations and may not accurately reflect infectious activity. In this study, we aim to define HSV-2/syphilis incidence and risk factors in a population sample. METHODS: We conducted a longitudinal population-based survey in Andhra Pradesh, India, in two rounds: 2004-2005 and 2010-2011. Sociodemographic and behavioural data were collected, and dried blood spots tested for HSV-2 and Treponema pallidum IgG. After calculating sexually transmitted infection (STI) incidence, associated factors were assessed using modified Poisson regression and within-couple transmission rates modelled using seroconcordance/discordance data. RESULTS: 12,617 adults participated at baseline with 8494 at follow-up. Incidence of HSV-2 and syphilis per 1000 person-years was 25.6 (95% CI 24.1 to 27.2) and 3.00 (95% CI 2.52 to 3.54). Incidence of HSV-2 was higher in women vs. men (31.1 vs. 20.2) and in rural vs urban residents (31.1 vs 19.0) (p<0.05 for both). STI seroincidence increased in a step-wise fashion with age and was associated with spousal seropositivity for both sexes (incidence rate ratio (IRR) 2.59 to 6.78). Within couples the rate of transmission per 1000 couple-years from men to women vs. women to men was higher for HSV-2 (193.3 vs. 119.0) compared with syphilis (27.6 vs. 198.8), p<0.05 for both. CONCLUSIONS: HSV-2 has higher incidence among subpopulations such as women, rural residents and older-aged individuals, suggesting a need for more generalised STI prevention approaches among populations traditionally considered low risk.

Globally, around 150 million people are infected with hepatitis C virus (HCV). India contributes a large proportion of this HCV burden. The prevalence of HCV infection in India is estimated at between 0.5% and 1.5%. It is higher in the northeastern part, tribal populations and Punjab, areas which may represent HCV hotspots, and is lower in western and eastern parts of the country. The predominant modes of HCV transmission in India are blood transfusion and unsafe therapeutic injections. There is a need for large field studies to better understand HCV epidemiology and identify high-prevalence areas, and to identify and spread awareness about the modes of transmission of this infection in an attempt to prevent disease transmission.
ABSTRACT
The estimated prevalence of hepatitis C virus (HCV) infection in India is between 0.5 and 1.5% with hotspots showing much higher prevalence in some areas of northeast India, in some tribal populations and in certain parts of Punjab. Genotype 3 is the most prevalent type of infection. Recent years have seen development of a large number of new molecules that are revolutionizing the treatment of hepatitis C. Some of the new directly acting agents (DAAs) like sofosbuvir have been called game-changers because they offer the prospect of interferon-free regimens for the treatment of HCV infection. These new drugs have not yet been approved in India and their cost and availability is uncertain at present. Till these drugs become available at an affordable cost, the treatment that was standard of care for the whole world before these newer drugs were approved should continue to be recommended. For India, cheaper options, which are as effective as the standard-of-care (SOC) in carefully selected patients, are also explored to bring treatment within reach of poorer patients. It may be prudent to withhold treatment at present for selected patients with genotype 1 or 4 infection and low levels of fibrosis (F1 or F2), and for patients who are non-responders to initial therapy, interferon intolerant, those with decompensated liver disease, and patients in special populations such as stable patients after liver and kidney transplantation, HIV co-infected patients and those with cirrhosis of liver.
ABSTRACT
INTRODUCTION: We undertook a prospective community-based study in North Jakarta, Indonesia, to determine the incidence, clinical characteristics, seasonality, etiologic agent, and antimicrobial susceptibility pattern of enteric fever. METHODOLOGY: Following a census, treatment centre-based surveillance for febrile illness was conducted for two-years. Clinical data and a blood culture were obtained from each patient. RESULTS: In a population of 160,261, we detected 296 laboratory-confirmed enteric fever cases during the surveillance period, of which 221 (75%) were typhoid fever and 75 (25%) were paratyphoid fever. The overall incidence of typhoid and paratyphoid cases was 1.4, and 0.5 per thousand populations per year, respectively. Although the incidence of febrile episodes evaluated was highest among children under 5 years of age at 92.6 per thousand persons per year, we found that the burden of typhoid fever was greatest among children between 5 and 20 years of age. Paratyphoid fever occurred most commonly in children and was infrequent in adults. CONCLUSION: Enteric fever is a public health problem in North Jakarta with a substantial proportion due to paratyphoid fever. The results highlight the need for control strategies against enteric fever.

BACKGROUND: Understanding about who acquires new HIV infection and the determinants of why some persons get infected and others do not is fundamental to controlling HIV in the population. We assess HIV incidence and its associations in the population of a high HIV burden district in Andhra Pradesh state in southern India by a population-based longitudinal cohort study. METHODS: We re-surveyed a population-based cohort of 12,617 adults in Guntur district of Andhra Pradesh for which we had reported a baseline HIV prevalence of 1.72% (rural 1.64%, urban 1.89%) among the 15-49 years age group in 2004-2005. We conducted interviews to assess risk behaviour and performed HIV testing again in 2010-2011. We assessed the rate of new HIV infection and its associations using multiple logistic regression. RESULTS: The participation rate in the follow-up was 74.9% and 63.9% of the baseline rural and urban samples, respectively. Over a mean follow-up of 5.63 years, the incidence of HIV was 1.26 per 1000 person-years (95% CI 0.83-1.69), after adjusting for slight compositional bias in the follow-up sample. The incidence per 1000 person-years was higher among rural men (1.68) than urban men (0.85), and among rural women (1.28) than urban women (0.54). The strongest association with incidence was a HIV positive spouse in the baseline for both men (odds ratio 266, 95% CI 62-1137) and women (odds ratio 28, 95% CI 9-88). Among men the other significant associations with HIV incidence were frequent use of condom for sex over the past 6 months, non-circumcision, more than one lifetime woman sex partner or ever visited sex worker, and transport-related occupation; for women the other significant associations were having had HIV testing other than antenatal check-up, previously married but currently not, and tobacco use. CONCLUSION: These first population-based cohort incidence data from India suggest that rural areas of high HIV burden states would need more attention to prevent new HIV infections, and that spouses of HIV positive persons and some other risk groups need to be targeted more effectively by HIV prevention programmes.

BACKGROUND: Bile analysis yields important information such as "biliary microlithiasis" and biliary tract colonization by microorganisms like Salmonella typhi or paratyphi, Escherichia coli, etc., which may progresses to cholelithiasis and have been found to have a role in the development of gallbladder cancer in India. AIM: To perform microscopic, cytomorphological and microbiological examination of bile collected during endoscopic retrograde cholangiopancreatography in patients with benign and malignant lesions of the gallbladder. MATERIALS AND METHODS: Bile was collected from 48 patients by a catheter inserted through the cystic duct during endoscopic retrograde cholangiopancreatography. Direct microscopy and grading of crystals was performed. Smears prepared from centrifuged deposits were stained with Giemsa, Papanicolaou stain and Gram's stain for cytological and microbiological examination. Special staining for Helicobacter pylori was performed using Loeffler's Methylene blue and Warthin Starry stain. The rest of the sample was used for culture and complete microbiological examination. RESULTS: Thirty-six patients had inflammatory lesions while 12 had malignant lesions. Crystals were observed in 93% of the cases, 13 (28.8%) had only cholesterol crystals, three (6.6%) had bilirubinate and 29 (64.4%) had both cholesterol and bilirubinate crystals. Smears from the centrifuged deposit mainly showed coccoid or cocobacillary bacteria on Gram's staining (81.3%). Five of 12 (41.6%) malignant cases showed epithelial atypia while none of the benign or inflammatory lesions showed such a change in hematoxylin and eosin and Pap-stained smears. Microbiologic analysis showed Staphylococcus aureus (14%), S. saprophyticus (5.5%), Peptococcus (5.5%), Peptostreptococcus (5.5%), Proteus mirabilis (5.5%), E. coli (17%), Enteorbacter cloacae (5.5%) and H. pylori (2.8%). CONCLUSION: Complete microscopic and microbiological examination of bile directly obtained from the common bile duct during endoscopic retrograde cholangiopancreatography yielded good results as fresh samples could be analyzed. It may help in diagnosis of many gallbladder lesions in early stages, thereby reducing the morbidity and mortality.

Charcot Leyden crystals are hexagonal bipyramidal structures localised in the primary granules of the cytoplasm of eosinophils and basophils. Their presence, along with eosinophilic infiltrate, is an indirect evidence of parasitic infestation particularly with Toxocara, Capilliriasis, Ascariasis, or Fasciola. We report here two cases where Charcot Leyden crystals with eosinophilic infiltrate were found in the smears prepared from hepatic abscess.
ABSTRACT
Herpes simplex virus 2 (HSV-2) and, to a lesser extent, HSV-1 cause the majority of sexually transmitted genital ulcerative disease. No effective prophylactic vaccine is currently available. Replication-defective HSV stimulates immune responses in animals but produces no progeny virus, making it potentially useful as a safe form of live vaccine against HSV. Because it does not replicate and spread in the host, however, replication-defective virus may have relatively limited capacity to solicit professional antigen presentation. We previously demonstrated that in mice devoid of B7-1 and B7-2 costimulation molecules, replication-defective HSV-2 encoding B7-1 or B7-2 induces stronger immune responses and protection against HSV-2 challenge than immunization with replication-defective virus alone. Here, we vaccinated wild-type mice fully competent to express endogenous B7 costimulation molecules with replication-defective HSV-2 or replication-defective virus encoding B7-2 and compared their capacities to protect against vaginal HSV-2 infection and disease. Replication-defective virus encoding B7-2 induced more IFN-gamma-producing CD4 T cells than did replication-defective virus alone. Immunization with B7-2-expressing virus decreased challenge virus replication in the vaginal mucosa, genital and neurological disease, and mortality more effectively than did immunization with the parental replication-defective virus. Prior immunization with B7-expressing, replication-defective virus also effectively suppressed infection of the nervous system compared to immunization with the parental virus. Thus, B7 costimulation molecules expressed at the site of HSV infection can enhance vaccine efficacy even in a fully immunocompetent host.

The interaction between B7 costimulation molecules on antigen-presenting cells and CD28 on antigen-responsive T cells is essential for T-cell activation and maturation of immune responses to herpes simplex virus (HSV) infection. Vaccine-induced immune responses also depend upon adequate upregulation of B7 costimulation molecules, but this signal may be limiting for replication-defective virus vaccines. We investigated whether expression of B7 costimulation molecules by a prototypical replication-defective antiviral vaccine could enhance immune responses to the vaccine and whether B7-1 and B7-2 would be similarly effective. We altered an ICP8(-) replication-defective strain of HSV type 2 (HSV-2), 5BlacZ, to encode either murine B7-1 or B7-2. B7 molecule expression was detected on the surface of cells infected in vitro and at the RNA level in tissue of immunized mice. Immunization of B7-1/B7-2 knockout mice with B7-encoding virus modestly expanded the number of gamma interferon-producing T cells and significantly augmented class-switched HSV-specific antibody responses compared with the parental virus. Mice immunized with either B7-expressing virus showed less replication of challenge virus in the genital mucosa than mice immunized with 5BlacZ, markedly fewer signs of genital and neurological disease, and little weight loss. Virtually all mice immunized with B7-encoding virus survived challenge with a large dose of HSV-2, whereas most 5BlacZ-immunized mice succumbed to infection. These results indicate that protective immune responses can be enhanced by the inclusion of host B7 costimulation molecules in a prototypical replication-defective HSV vaccine against HSV-2 genital infection and that B7-1 and B7-2 induce immune responses with similar capacities to fight HSV-2 infection.

Ghee (clarified butter oil), a major ingredient in Indian sweets, is an important source of saturated fatty acids, cholesterol and cholesterol oxidation products (COP) that are considered risk factors for atherosclerosis. The high frequency of atherosclerotic complications reported among the Indian immigrants in England prompted determination of lipids and lipid oxidation status of a ghee sample and 15 Indian sweets available in London supermarkets. The fatty acid profile of the samples shows saturated fats (about 73%), mainly composed of myristic, palmitic and stearic acids, except in two samples. There were large variations in thio-barbituric acid reacting substance values (19-260 microg/100 g) and total COP (1.4-51.2 microg/g lipids) among the sweet samples. Regular consumption of some of these sweets can be a source of considerable amounts of saturated fatty acids, cholesterol and COP in the diet and may contribute to atherosclerosis.

Hereditary spastic paraplegia (HSP) is a genetically determined condition that is often confused with, and misdiagnosed as, spastic diplegic cerebral palsy. Both autosomal dominant and recessive forms have been reported. We present three index patients in a single family with this disease. The pedigree of three generations strongly supports the genetic basis of an autosomal dominant condition. Awareness of this entity may help in genetic counseling and possibly avoiding some medical litigation related to cerebral palsy patients.

Although cat-scratch disease is not uncommonly treated by pediatricians, it is rarely seen by orthopaedists. In this review of cat-scratch disease, two cases with orthopaedic manifestations are high-lighted. One patient had a positive bone scan in the distal humerus that simulated osteomyelitis on presentation. The second patient presented with a rapidly enlarging soft-tissue mass in the arm that resembled a soft-tissue sarcoma. The diagnosis of cat-scratch disease eventually was made late in the course of management in both cases. Both patients underwent surgical drainage and evacuation of the suppurated lymph node and recovered without sequelae.
