Post-Endoscopy Parotid Swelling: A Rare Complication.

Parotid gland swelling, or parotitis, typically associated with infectious causes, can uncommonly result from non-infectious factors such as mechanical trauma following endoscopic procedures. We present a case of a 46-year-old female with liver cirrhosis who developed right parotid swelling shortly after undergoing endoscopy for evaluation of gastrointestinal symptoms. The patient's clinical course, imaging findings, and successful resolution with conservative measures are detailed. The etiology of post-endoscopy parotid swelling is multifactorial, involving potential mechanisms such as mechanical trauma, salivary gland dysfunction, infection, ductal obstruction, or allergic reactions to medications. Diagnosing this rare complication requires a comprehensive clinical evaluation, including a detailed history, symptom assessment, and imaging studies such as ultrasound. Management involves a combination of symptomatic relief, identification, and treatment of the underlying cause, emphasizing the importance of early recognition to prevent complications. In our case, warm compression provided pain relief, and the swelling subsided without the need for medical or surgical intervention. Regular follow-up evaluations and imaging studies are crucial to assess treatment response and ensure the resolution of the swelling. This case contributes to the limited literature on post-endoscopy parotid swelling, emphasizing the significance of recognizing and managing this rare complication promptly. Healthcare professionals should be vigilant, and further research is encouraged to better understand its pathophysiology and optimize management strategies in order to improve patient outcomes.

An Uncommon Encounter: A Comprehensive Case Report of an Advanced Esophageal Neuroendocrine Carcinoma.

Esophageal neuroendocrine carcinomas (E-NECs) are rare malignant tumors with unknown etiology and pathogenesis. The aggressive nature of E-NECs coupled with a tendency to metastasize and no available treatment guidelines lead to poor prognosis. Here, we report a case of a 65-year-old, previously healthy female who presented with difficulty in swallowing solids, burning sensation over the epigastric region, weight loss (>10%), and altered bowel habits for the last three months. Contrast-enhanced CT (CECT) thorax revealed asymmetric mid-esophageal wall thickening with lymphadenopathy and metastasis in both hepatic lobes. Esophageal endoscopy revealed a large circumferential ulcero-proliferative mass and umbilicated lesions. A histopathological examination revealed small cells with scant cytoplasm and pleomorphic, hyperchromatic nuclei with prominent nuclear molding, and extensive necrosis. Immunohistochemistry revealed positivity for synaptophysin, chromogranin A, and CD56. Ki-67 index was 53%. These findings suggested poorly differentiated, small cell type, high-grade E-NEC. Chemotherapy with cisplatin (30mg/m2) + irinotecan (60mg/m2) was initiated. However, following two chemotherapy cycles, the patient succumbed.

Early virus clearance of SARS-CoV-2 among co-infection with malaria.

BACKGROUND AND OBJECTIVES: India has witnessed significant number of cases of co-infection of malaria or dengue with COVID-19, especially during the monsoon season. It has been speculated that anti-malarial immunity might have a protective role in co-infection. Retrospective analysis of co-infection of vector-borne diseases with COVID-19 was done for comparing their remission with matched controls with COVID-19 by means of epidemiological data. METHODS: Medical case records of patients with co-infection of malaria or dengue with COVID-19 admitted at TNMC and BYL Nair Charitable Hospital from 1 March 2020 to 31 October 2020 were analyzed retrospectively. Out of 91 cases of co-infection of SARS-CoV-2 infection with vector-borne diseases, virus clearance (VC) analysis was done for 61 co-infections with malaria. RESULTS: Median duration of VC for co-infection with malaria was 8 days whereas, it was 12 days for controls with COVID-19 (p=0.056). Young patients (≤50 years) with co-infection recovered faster than controls age (p=0.018). INTERPRETATION & CONCLUSION: Co-infection with malaria is associated with less severe disease and early recovery in the form of early VC. Genetic and immunological studies are necessary to confirm malaria protection against SARS-CoV-2 infection.

Spectrum of viral hepatitis in hospitalized children in western India.

Viral hepatitis is a major public health problem affecting children globally. Clinical presentation varies from asymptomatic illness to hepatitis, and liver failure. Data on clinical features and laboratory parameters were collected and analysed on 300 children, aged 1-12 years, admitted with confirmed viral hepatitis. A small majority (52%) were boys. The mean age of presentation was 6.9 ± 2.8 years with the commonest symptoms being anorexia or vomiting (in 98%), fever (in 89%) and jaundice (in 71.3%). Tender hepatomegaly was seen in 31.7%. Almost all (97.6%) had hepatitis A, though mixed infection (A & E) was seen in 1.7%. Only 8% had serum bilirubin levels >200 µmol/L. Significantly elevated (>20 µkat/L) levels of aspartate transaminase and alanine transaminase were seen in 19% and 25.3% of cases respectively. Coagulopathy (PT >15 s) was present in 11.0% cases. HAV remains the most common cause of viral hepatitis in children in our environment. Public awareness and universal vaccination should be the focus to prevent morbidity and mortality due to these pathogens.

Normal Values of High-resolution Anorectal Manometry of Healthy Indians.

Background/Aims: High-resolution anorectal manometry (HRAM) measures anal sphincter function and anorectal co-ordination. This study aims to provide normal data for HRAM and evaluate the effect of gender, age, and body mass index (BMI) on anorectal functions in healthy Indian subjects. Methods: HRAM was performed on 93 healthy volunteers using a 20-channel, water-perfused catheter. We evaluated anorectal pressures, rectal sensation, and balloon expulsion time. Measurements were recorded during rest, squeeze, and simulated defecation (push). Results: Median anal resting pressure (88 mmHg vs 94 mmHg, P = NS), anal squeeze pressure (165 mmHg vs 147 mmHg, P = NS) were not significantly different between males and females. Rectal pressure (70 mmHg vs 54 mmHg, P = 0.024) and anal pressure (82 mmHg vs 63 mmHg, P = 0.008) during simulated evacuation without rectal distention, were higher in males. The threshold for the first sensation was lower in females (40 mL vs 30 mL, P = 0.021) but desire to defecate (105 mL vs 90 mL, P = NS) and maximum tolerable volume (160 mL vs 140 mL, P = NS) were not significantly different in males and females. Anal residual pressure (median mmHg 83 vs 71 mmHg, P = 0.025) was higher in subjects < 40 years of age. Maximum anal squeeze pressure (185 mmHg vs 165 mmHg, P = 0.024) and maximum rectal pressure (75 mmHg vs 62 mmHg, P = 0.032) during push higher in BMI < 23 kg/m2. Conclusions: The present study provides normal data for the Indian population that can be used for comparison and further work. Age, gender, and BMI affect anorectal parameters in HRAM and should be considered while reporting.

HEPATIC DYSFUNCTION IN MEDICAL INTENSIVE CAREUNIT PATIENTS PREDICTS POOR OUTCOME.

BACKGROUND: A large number of patients admitted to the medical intensive care unit (MICU) have abnormal liver function tests (LFT). This includes patients with critical illness with or without preexisting liver disease and patients with acute primary liver injury. There are very few studies which have investigated the spectrum of liver disease, clinical profile and outcome in patients admitted to the MICU. OBJECTIVE: To evaluate the occurrence, etiology, clinical profile, laboratory profile and outcome of hepatic dysfunction in patients admitted to the MICU. To evaluate the utility of model for end-stage liver disease (MELD) score on admission as a predictor of adverse short term outcome in patients with hepatic dysfunction admitted in MICU. METHODS: It was a prospective observational study, conducted from December 2017 to December 2018 in a tertiary care hospital. Two hundred and two patients admitted to the MICU with LFTs as per the inclusion criteria were analyzed and their short-term outcome at 7 days was studied in relation to various parameters. RESULTS: LFT abnormalities were present in 202/1126 (17.9%) of the patients admitted to MICU. Critical illness associated liver dysfunction was found in 172 (85.2%) patients, chronic liver disease in 11 (5.4%) patients and acute viral hepatitis in 19 (9.4%) patients. Most common symptom was fever (68.3%) followed by vomiting (48.0%). Among LFT abnormalities, elevated transaminases, raised international normalized ratio and high MELD score on admission correlated with poor short-term outcome. Requirement for inotropes and mechanical ventilation correlated with poor short-term outcome. Mortality did not differ significantly between patients with chronic liver disease, patients with acute viral hepatitis and patients with critical illness associated hepatic dysfunction. Hepatic dysfunction in MICU was associated with poor outcome and a high short-term mortality of 56.4% (114/202). CONCLUSION: Liver function abnormality is common in patients who are admitted to the MICU and its presence is an indicator of poor short-term outcome.

RESUMO Contexto: Um grande número de pacientes internados na unidade de terapia intensiva (UTI) tem testes de função hepática anormais (TFH). Isso inclui pacientes com doença crítica com ou sem doença hepática pré-existente e pacientes com lesão hepática primária aguda. Há poucos estudos que têm investigado o espectro da doença hepática, perfil clínico e desfecho em pacientes admitidos em UTI. Objetivo Avaliar a ocorrência, etiologia, perfil clínico, perfil laboratorial e desfecho de disfunção hepática em pacientes internados na UTI médica. Avaliar a utilidade do modelo para doença hepática em estágio terminal (MELD). Escore na admissão como preditor de desfecho adverso a curto prazo em pacientes com disfunção hepática admitida em UTI. Métodos: Foi realizado um estudo observacional prospectivo, de dezembro de 2017 a dezembro de 2018 em um hospital de atenção terciária. Foram analisados 202 pacientes internados na UTI com TFH conforme os critérios de inclusão e seu desfecho a curto prazo de 7 dias foi estudado em relação a diversos parâmetros. Resultados: Anormalidades dos testes estiveram presentes em 202/1126 (17,9%) dos pacientes internados na UTI. Doença crítica associada à disfunção hepática foi encontrada em 172 (85,2%) pacientes, doença hepática crônica em 11 (5,4%) pacientes e hepatite viral aguda em 19 (9,4%) pacientes. O sintoma mais comum foi a febre (68,3%), seguido de vômito (48,0%) casos. Entre as anormalidades do TFH, transaminases elevadas, INR e escore MELD elevados na admissão correlacionaram-se com desfecho ruim de curto prazo. Exigência de inotrópicos e ventilação mecânica correlacionaram-se com desfecho de curto prazo ruim. A mortalidade não diferiu significativamente entre pacientes com doença hepática crônica, pacientes com hepatite viral aguda e pacientes com doença crítica associada à disfunção hepática. A disfunção hepática em UTI esteve associada a um desfecho ruim e à uma alta mortalidade a curto prazo de 114/202 (56,4%). Conclusão: A anormalidade da função hepática é comum em pacientes que são admitidos nas unidades de tratamento intensivo e sua presença é um indicador de desfecho de curto prazo ruim.

Pattern of liver function test variations in COVID-19 infection & its clinical significance: A study from a dedicated COVID-19 tertiary care centre from India.

Background & objectives: Coronavirus disease 2019 (COVID-19) affects respiratory, gastrointestinal, cardiovascular and other systems disease. Studies describing liver involvement and liver function test (LFT) abnormalities are sparse from our population. This study was undertaken to estimate the LFT abnormalities in patients with COVID-19 in a tertiary care set up in India. Methods: In this retrospective study conducted at a tertiary care centre in Mumbai, India, all consecutive patients with proven COVID-19 by reverse transcriptase-PCR from March 23 to October 31, 2020 were enrolled. Of the 3280 case records profiled, 1474 cases were included in the study. Clinical characteristics, biochemical parameters and outcomes were recorded. Results: Overall 681 (46%) patient had deranged LFTs. Hepatocellular type of injury was most common (93%). Patients with deranged LFTs had more probability of developing severe disease (P<0.001) and mortality (P<0.001). Advanced age (P<0.001), male gender (P<0.001), diabetes mellitus (P<0.001), lower oxygen saturation levels at admission (P<0.001), higher neutrophil-lymphocyte ratio (P<0.001), history of diabetes mellitus and cirrhosiss were associated with deranged LFTs. Acute liver injury was seen in 65 (4.3%) cases on admission and 57 (3.5%) cases during hospital stay. On multivariate analysis for predicting mortality, age >60 yr serum creatinine >2 mg%, PaO2/FiO2 ratio ≤200 and raised AST >50 IU/l (OR: 2.34, CI: 1.59-3.48, P<0.001) were found to be significant. Interpretation & conclusions: In COVID-19, LFT abnormalities were common, and derangement increased as severity progressed. The presence of deranged LFT worsens the clinical outcome and predicts in-hospital mortality.

"The Innate Tail": An Unusual Cause of Rectal Bleeding in an Adult Male.

Retrorectal cystic hamartomas or tailgut cysts are infrequent congenital lesions presenting as presacral masses originating from the embryonic hindgut. They are commonly diagnosed in middle-aged women. Physicians must have a high index of suspicion to diagnose this rare tumor. We report a case of retrorectal hamartoma in a 70-year-old male presenting as rectal bleeding instead of the usual compressive symptoms. The utility of imaging modalities and the paramount importance of histopathology has been described. The treatment modality is surgical excision to prevent the potential malignant transformation.

Hamartomas císticos retrorretais ou "tailgut cysts" sao lesóes congénitas pouco frequentes que se originam do intestino posterior embrionário e que se apresentam como massas pré-sagradas. São comumente diagnosticados em mulheres de meia-idade. Os médicos devem ter um elevado grau de suspeição para diagnosticar este tumor raro. Relatamos um caso de um hamartoma retrorretal num homem com 70 anos de idade que se apresentou com retorragias e não com os sintomas mais comuns de obstrução. A utilidade dos exames de imagem e a grande importância da histopatologia foi demonstrada neste caso. A modalidade terapêutica adoptada foi a excisão cirúrgica para prevenir uma transformação maligna potencial.

Primary pancreatic tuberculosis with a duodenal fistula in an immunocompetent young man.

Tuberculosis (TB) is a common disease in developing countries that can virtually affect any organ in the body. The abdomen is one of the most common sites for extra-pulmonary tuberculosis. Primary Pancreatic tuberculosis (PPTB) is rare and can be clinically elusive. It is commonly encountered in immunodeficient individuals in regions endemic for TB. However, it is extremely rare in immunocompetent individuals with very few case reports in the literature. We describe a case of PPTB in an immunocompetent young man complicated with duodenal fistula. There was complete resolution of symptoms and the fistulous tract with a significant reduction of the size of the lesion on imaging after 6 months of anti-tubercular therapy (ATT).

Effect of moderate aerobic exercises on symptoms of functional dyspepsia.

BACKGROUND: Functional dyspepsia (FD) is a commonly encountered entity worldwide and is difficult to treat. Most of the treatment modalities have low-quality evidence for use, except for proton pump inhibitors. Aerobic exercise has been shown to improve the symptoms, but its direct effect on symptoms has never been studied. The objective was to study the effects of moderate aerobic exercise on symptoms of FD and to compare the effect of conventional treatment alone vs. exercise plus conventional treatment. METHODS: Out of 112 patients, 72 were randomly divided into controls (conventional treatment; n=36) and experimental (aerobic exercise for 30 min per session, 5 times a week for 6 weeks with conventional treatment; n=36) groups. Both the groups were assessed on day 1 and at the end of 6 weeks, using Glasgow Dyspepsia Severity Score (GDSS), Depression Anxiety Stress Scales-42 (DASS-42), and visual analogue scale (VAS). RESULTS: Pre-treatment GDSS, DASS-42, and VAS in the experimental group were significantly different as compared to the post-treatment scores (p=0.00019, p=0.0002, p=0.00019, respectively). Even in the control group, pre- and post-treatment GDSS, DASS-42, and VAS scores were significantly different (p=0.00019, p=0.0002, p=0.00019, respectively). However, on the head-to-head comparison of the 2 groups, scores at the end of 6 weeks were significantly different (p< 0.05), in favor of the experimental group. CONCLUSION: Aerobic exercise as an auxiliary therapy to conventional treatment has better outcomes in the functional well-being of dyspepsia.

Complete hemogram: simple and cost-effective in staging and predicting outcome in acute pancreatitis.

BACKGROUND: An important goal in management of acute pancreatitis (AP) is early prediction and recognition of disease severity. Various predictive scoring systems are in clinical use with their own limitations and there is always a quest for simple, practical, quantifiable, dynamic and readily available markers for predicting disease severity and outcome. Complete hemogram is routinely ordered in all patients with AP. In recent years red cell distribution width (RDW), neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR) and platelet lymphocyte ratio (PLR) have been found to be independent predictors of prognosis in various benign and malignant conditions. This prospective study evaluated complete hemogram based markers in AP. MATERIAL AND METHODS: Complete hemogram analysis was done and NLR, LMR, PLR values were calculated. Development of organ failure, the need for intensive care unit (ICU) admission and interventions, development of complications (local/systemic) and 100-day mortality were assessed. RESULTS: In this study 160 subjects of AP were included. Complete hemogram analysis was performed within 24 h after admission. C­reactive protein, RDW, NLR, PLR and bedside index of severity in acute pancreatitis (BISAP) values were higher in severe AP than moderate AP group than mild AP group, while LMR values were decreased in the corresponding severe, moderate and mild AP groups (p < 0.001). The NLR performed best for prediction of ICU admission, organ failure, interventions and mortality with area under receiver operating curve (AUROC) were 0.943, 0.940, 0.902 and 0.910, respectively. CONCLUSION: Hemogram based markers are simple, objective, dynamic and readily available. They can be considered in addition to conventional multifactorial scoring systems for prediction of outcome and prognosis of AP.

A new model to predict response to direct-acting antiviral therapy in decompensated cirrhotics due to hepatitis C virus.

AIM: of the study: Decompensated hepatitis C virus (HCV) cirrhosis is a difficult to treat cohort, and there is no gold standard predictor of response to direct-acting antiviral (DAA) therapy. We conducted this study to look for factors responsible for improvement in post-therapy status, i.e. attainment of Child-Turcotte-Pugh (CTP) class A from B or C, and devise a new model to predict post-therapy response. MATERIAL: and methods: Prospective analysis of data from decompensated HCV cirrhotics was done and association of each parameter with patient outcomes at 36 weeks after treatment was assessed. RESULTS: 34 patients (54.8%) attained CTP class A after treatment. Factors that were independently associated with disease outcome included albumin (odds ratio [OR] = 4.84, 95% confidence interval [CI]: 1.43-20.15, p = 0.018), alanine transaminase (ALT) (OR = 1.02, 95% CI: 1-1.04, p = 0.049), bilirubin (OR = 0.41, 95% CI: 0.2-0.75, p = 0.007) and estimated glomerular filtration rate (eGFR) (OR = 1.03, 95% CI: 1.0-1.06, p = 0.045). On multivariate analysis, bilirubin was significantly associated with treatment outcome (OR = 0.28, 95% CI: 0.1-0.64, p = 0.006). A composite model was devised using demographic, biochemical, and clinical features, which has sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 67.86%, 79.41%, 73.08%, 75%, and 73.63% respectively in predicting response to therapy. Only 7.6% of patients with a Model for End-Stage Liver Disease (MELD) score > 15 and none of the patients with CTP class C met the primary end-point of our study. CONCLUSIONS: 55% of our cohort met the primary end-point at 36 weeks. Patients with CTP class C and a MELD score > 15 should be referred for liver transplantation followed by DAA therapy. Our model was good at predicting improvement in post-therapy liver function.

Clinical, serological, histopathological and treatment profile of autoimmune hepatitis in the elderly.

AIM OF THE STUDY: Autoimmune hepatitis (AIH), despite being uncommon, is on the rise in the elderly population. However, no study from India has described the natural history and treatment outcome of AIH in the elderly. The aim was to study the characteristics of AIH in the elderly population and compare them with the younger population. MATERIAL AND METHODS: Patients with a diagnosis of AIH based on the revised International Autoimmune Hepatitis Group (IAIHG) criteria were recruited from January 2011 to June 2018. Patients were defined as elderly when ≥ 60 years and young when < 60 years of age. Clinical, serological, histological characteristics and treatment outcome with follow-up until 12 months were analyzed and compared between the two groups. RESULTS: Out of 155 patients, 33 (21.29%) were elderly. Acute-on-chronic liver failure (ACLF) as the presentation was more common in elderly as compared to young AIH patients (39.4% vs. 13.9%, p = 0.0024). Serum alanine aminotransferases and serum creatinine levels were significantly higher in elderly patients as compared to the younger group (p < 0.05). On histology cirrhosis was significantly more common in the elderly group (75.7% vs. 56.6%, p = 0.045). Response to treatment at the end of 12 months was similar in both groups. Due to co-morbidities immunosuppressant could not be started in 18.2% of elderly and 6.5% of younger patients (p = 0.065). CONCLUSIONS: AIH is an important differential diagnosis among the elderly population presenting with ACLF and cirrhosis. When given appropriate immunosuppressants they have a similar outcome as compared to the youngest population.

Acute Pancreatitis: A Rare Post-Colonoscopy Sequela.

Abdominal pain is a common but benign symptom after colonoscopy. We report a case of acute pancreatitis that occurred just after an elective screening colonoscopy; this is a rare event with very few reported cases. A healthy, asymptomatic male underwent screening colonoscopy at our center and developed abdominal pain and emesis after the procedure. An abdominal X-ray ruled out perforation but laboratory tests revealed elevated levels of amylase and lipase. The patient had no etiological risk factors for pancreatitis. The presumed mechanism of pancreatitis in this case is mechanical and pressure trauma from excessive insufflation, external abdominal pressure, and repeated withdrawal of the colonoscope due to tight angulation of the splenic flexure, a structure that is in close proximity to the pancreatic tail. Acute pancreatitis should be considered in the differential diagnosis of patients who present with abdominal pain after colonoscopy once more common etiologies have been excluded.

Splanchnic Venous Thrombosis in Acute Pancreatitis: Does Anticoagulation Affect Outcome?

BACKGROUND: Splanchnic venous system thrombosis is a well recognized local vascular complication of acute pancreatitis (AP). It may involve thrombosis of splenic vein (SplV), portal vein (PV) and superior mesenteric vein (SMV), either separately or in combinations, and often detected incidentally, indeed some cases present with upper gastrointestinal bleed, bowel ischemia and hepatic decompensation. Incidence is variable depending on study subjects and diagnostic modalities. Pathogenesis is multifactorial centered on local and systemic inflammation. Management involves treatment of underlying AP and its complications. Universal use of anticoagulation may lead to increased risk of bleeding due to frequent need of interventions (radiologic/endoscopic/surgical). Literature on anticoagulation in setting of AP is sparse and at present there is no consensus guideline on it. Current article details our experience on splanchnic venous thrombosis (SVT) in AP in a well defined cohort of patients at a tertiary care center. METHODS: Hospitalized patients with AP from January 2018 to December 2018 were included in the study. Detailed information on demographic, clinical, laboratory, radiologic features, and indication of anticoagulation use were collected prospectively during the index admission. Outcome variables were analyzed at the end of 6 months. RESULTS: Twenty four out of 105 (22.85%) patients with AP develop SVT. Etiology of AP was alcohol use in 21/24 (87.5%) subjects. Most common vessel involved was isolated SplV in 11/24 (45.8%) patients followed by SplV along with PV and SMV 9/24 (37.50%, P < 0.001). Bowel ischemia 4/12 (33.3%), hepatic decompensation 3/12 (25%), triple vessel involvement 4/12 (33.3%) and pulmonary embolism 1/12 (8.3%) were reasons for anticoagulation. There was no statistical difference with respect to development of varices, collateral formation, recanalization, bleeding and mortality with use of anticoagulation (P > 0.05 with respect to all above variables). CONCLUSIONS: SVT is commonly seen in alcohol-induced AP. Anticoagulation does not affect outcomes of SVT. Subset of patients may benefit with anticoagulation.

Endoscopic ultrasound-guided-fine-needle aspiration/fine-needle biopsy in diagnosis of mediastinal lymphadenopathy - A boon.

BACKGROUND/OBJECTIVES: Evaluation of mediastinal lymphadenopathy (MLA) is a great diagnostic challenge considering the myriad of causes. In recent years, the role of endoscopic ultrasound (EUS) has been greatly extended in evaluation of MLA due to its safety, reliability, and accuracy. The present study details the role of EUS-guided-fine-needle aspiration/fine-needle biopsy (EUS-FNA/FNB) in MLA of unknown origin. METHODS: Seventy-two patients (34 men) with MLA of unknown etiology were studied. Mediastinum was evaluated with linear echoendoscope and FNA/FNB was performed with 22-G needle and sent for cytology, histopathological, and mycobacterial growth indicator tube/GeneXpert evaluation. EUS-FNA/FNB diagnosis was based on cytology reporting by pathologists. Patients tolerated the procedure, and insertion of needle into the lesion was always successful without any complications. RESULTS: EUS-FNA/FNB established a tissue diagnosis in 66/72 patients in first sitting, while six patients underwent repeat procedure. EUS-FNA diagnoses (after second sitting) were tuberculous lymphadenitis in 45/72 (62.5%), metastatic lymph nodes 12/72 (16.7%), reactive lymphadenopathy 6/72 (8.3%), sarcoidosis 4/72 (5.6%), and lymphoma 2/72 (2.8%), while it was nondiagnostic in 3/72 (4.1%) patients. Final diagnosis was based on combined clinical presentation, EUS-FNA/FNB result and clinicoradiological response to treatment on long-term follow-up of 6 months. CONCLUSION: EUS echo features along with EUS-FNA/FNB can diagnose MLA and surgical biopsy can be avoided.

Factors Differentiating Acute Hepatitis B from Acute Exacerbation of Chronic Hepatitis B in Prospective-retrospective Cohort.

INTRODUCTION AND AIM: It is difficult to distinguish acute hepatitis B (AVH-B) from chronic hepatitis B with an acute exacerbation (CHB-AE) in patients whose prior history of HBV infection is unknown. The present study aimed to screen laboratory parameters at presentation to discriminate between these two conditions. MATERIALS AND METHODS: A prospective study was conducted in patients presenting clinically as AVH-B without known previous chronic hepatitis B status. Patients were divided into AVH-B and CHB-AE at end of six months follow up. Clinical and laboratory profiles were compared between these two groups at presentation. RESULTS: There was no significant difference in clinical presentation and risk factors profile in patients of both the groups. Mean age of presentation in AVH-B was 31.8 ± 14.9 years while, 47.2 ±17.3 years in CHB-AE group (p=0.005). Mean IgM anti-HBc levels were higher in AVH-B than in the CHB-AE group (p=0.001). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of IgM anti-HBc [>12.14 S/CO (Sample/Cut-off )] for diagnosis of AVH-B was 76.9%, 71.4%, 76.9% and 71.4 % respectively. Quantitative HBV DNA levels were significantly higher in CHB-AE group than in AVH-B group (p=0.015). Sensitivity, specificity, PPV and NPV of HBV DNA ( > 15390 IU/ml) for diagnosis of CHB-AE was 78.6%, 46.2%, 44% and 80% respectively. CONCLUSION: A high percentage of patients with apparent AVH-B might be cases of CHB-AE. Elderly patient (mean 47.2 years), high titers of HBV DNA (>15390 IU/ mL) and low IgM anti-HBc titer (<12.14 S/CO) favours CHB-AE over AVH-B.
