RESUMO
BACKGROUND: Mediastinal tubercular lymphadenitis is form of extrapulmonary tuberculosis [EPTB]. Clinical presentations are non-specific and diagnosis remains great clinical challenge. Microbiological and or histopathological evidences need to be present in order make diagnosis secure before initiation of anti-tubercular therapy (ATT). Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) provides tissue samples and aids management of this difficult to diagnosed entity. Current study describe role of EUS-FNA and Gene Xpert (GXP) in mediastinal tubercular lymphadenitis. METHODS: Retrospective analysis of 72 patients with mediastinal lymphadenopathy who underwent EUS-FNA were carried out. Linear echoendoscope was used for evaluation mediastinum. EUS echo features of LNs were studied. Twenty two-G needle used was for aspiration tissue sample from pathologic lymph nodes (LNs). FNA samples were analysed by cytology, Acid-Fast Bacilli (AFB) staining and GXP study. All procedures were uneventful without any complications. RESULTS: Forty two patients were diagnosed as tuberculosis (TB) following first EUS-FNA setting. Six patients underwent repeat EUS-FNA procedure following which another 3 were diagnosed as TB while remaining 3 started on empirical ATT based on additional supportive evidences. Forty five patients showed granulomatous inflammation on cytological analysis, AFB positivity noted in 16 (33.33%) patients while GXP in 26 (57.78%) patients. Rifampicin resistance detected in 3 ((6.25%) patients. All patients were followed clinico-radiologically for response to treatment. CONCLUSION: Tuberculous lymphadenitis is the most common cause of mediastinal lymphadenopathy in TB endemic countries. EUS-FNA provides microbiological and histopathological/cytological evidences in this difficult to diagnosed EPTB and thereby avoids empirical ATT.

BACKGROUND: Examining the distribution of biochemical and haematological tests in different age groups of rural population is necessary to ensure that health care facilities are equipped to address the prevalent health conditions and manage age-related illness effectively. Hence, this study is aimed at seeing the distributions of blood biochemical and haematological parameters in rural population. METHODS: This cross-sectional study investigated the distribution of 26 different haematological and biochemical parameters in longitudinal cohort study (Srinivaspura Aging, NeuoSenescence and COGnition - SANSCOG), from the villages of Srinivaspura, Kolar district, India. A total of 2592 participants (1240 males and 1352 females), aged ≥45 years who are cognitively healthy were included for the analysis. Mean, 2.5th, 5th, 25th, 50th, 75th, 95th and 97.5th percentiles were calculated for the entire sample. Additionally, median and percentiles were determined for both gender and age categories (45-54, 55-64, 65-74, and ≥75 years). RESULTS: We observed the distinct distributions of various haematological and biochemical parameters, with elevated levels of glycaemic, lipid, liver, and thyroid parameters. CONCLUSION: Findings revealed the notable variations from the established reference ranges, indicating the potential undiagnosed cases and highlighting the gaps in health awareness and health seeking behaviour.
RESUMO
Esophageal tuberculosis (TB) is a rare manifestation of extrapulmonary TB, accounting for <0.2% of all TB cases. Esophageal TB most commonly presents with dysphagia, odynophagia, retrosternal pain, and systemic symptoms like decreased appetite, loss of weight, and low-grade fever as associated or other presentations. We report a similar case recently encountered as an elderly male patient presented with chronic dysphagia to solids, loss of appetite, and significant loss of weight. Radiological and endoscopy pictures looked like esophageal cancer with histopathological examination (twice) negative for the same. Diagnosis of esophageal TB was confirmed by GeneXpert Ultra of biopsy sample and histopathological examination was suggestive of granulomatous esophagitis. The patient improved on 6 months antitubercular therapy. The unique aspect of this case was how the lesion mimicked an esophageal carcinoma on imaging which posed a diagnostic challenge.

BACKGROUND/AIMS: Patients of ulcerative colitis (UC) on follow-up are routinely evaluated by sigmoidoscopy. There is no prospective literature to support this practice. We assessed agreement between sigmoidoscopy and colonoscopy prospectively in patients with disease extent beyond the sigmoid colon. METHODS: We conducted a prospective observational study at a tertiary care institute for agreement between sigmoidoscopy and colonoscopy. We assessed endoscopic activity using the Mayo Endoscopic Score (MES) and Ulcerative Colitis Endoscopic Index of Severity (UCEIS) and histological activity using the Nancy Index (NI), Robarts Histopathology Index (RHI), and Simplified Geboes Score (SGS). RESULTS: Sigmoidoscopy showed a strong agreement with colonoscopy for MES and UCEIS with a kappa (κ) of 0.96 and 0.94 respectively. The misclassification rate for MES and UCEIS was 3% and 5% respectively. Sigmoidoscopy showed perfect agreement (κ = 1.00) with colonoscopy for assessment of the presence of endoscopic activity in the colon using MES ≥ 1 as activity criteria and strong agreement (κ = 0.93) using MES > 1 as activity criteria. Sigmoidoscopy showed strong agreement with colonoscopy for assessment of the presence of endoscopic activity using UCEIS (κ = 0.92). Strong agreement was observed between sigmoidoscopy and colonoscopy using NI (κ = 0.86), RHI (κ = 1.00), and SGS (κ = 0.92) for the detection of histological activity. The misclassification rate for the detection of histological activity was 2%, 0%, and 1% for NI, RHI, and SGS respectively. CONCLUSIONS: Sigmoidoscopy showed strong agreement with colonoscopy for endoscopic and histologic disease activity. Sigmoidoscopy is adequate for assessment of disease activity in patients with UC during follow-up evaluation.
RESUMO
Objectives: Recent studies have shown that multilingualism may play an important role in enhancing cognitive health. The process of language acquisition constitutes a form of natural brain training, which in turn is hypothesized to increase neuroplasticity and hence, maintains the cognitive reserve. The study aimed to analyze the relationship between the number of languages known to an individual and its effect on cognitive functioning in both healthy and cognitively impaired study participants. Materials and Methods: This study utilized cross-sectional (baseline) data from Srinivasapura Aging, Neuro Senescence and COGnition study, which is an ongoing community-based, longitudinal aging cohort study conducted in a rural setting in southern India. A total of 3725 participants were considered for the study. The participants were separated into two groups, namely, monolinguals (participants knowing one language) and multilingual (participants knowing more than one language). The cognitive performance of the participants was assessed using the Clinical Dementia Rating (CDR) Scale. In addition, bivariate analyses and binary logistic regression analyses were carried out. Results: The result of CDR scores with respect to language category shows that, among the monolingual participants, 86.5% were healthy individuals and 13.5% were with mild cognitive impairment (MCI). Similarly, among the multilingual, 94.3% were healthy and 5.7% were with MCI. The odds ratio value derived from logistic regression (0.69 95% CI (0.5-0.9)) that an individual has a higher chance of developing cognitive impairment if he/she is a monolingual. Conclusion: This study highlights that knowing more than one language might have a profound positive impact on cognitive health, thereby reducing the likelihood of developing cognitive decline.
RESUMO
BACKGROUND AND AIMS: Non-A-E hepatitis (NAEH) not leading to acute liver failure (ALF) is poorly documented. The objective was to compare clinical and laboratory features of uncomplicated acute NAEH with acute viral (AVH) and autoimmune hepatitis (AIH) and histopathology in NAEH and AIH. METHODS: Cases of hepatocellular jaundice were included. These were grouped into AVH, AIH and NAEH based on clinical, laboratory and, when indicated, liver biopsy findings. NAEH and AIH were followed up at three months. RESULTS: Of 336 patients with hepatocellular jaundice, 15 (5%) were NAEH, 25 (7%) acute AIH and 45 (14%) AVH. Among NAEH patients, seven (46.7%) were males with a mean age of presentation 39 years. Jaundice (100%) was the most common presentation of NAEH. Peak bilirubin was 10.7 mg/dL. Peak aspartate and alanine aminotransferase (AST, ALT) were 512 and 670 U/L. Five (33.3%) patients had positive anti-nuclear antibody and one had anti-smooth muscle antibody. Mean immunoglobulin G (IgG) levels were 1829. On liver biopsy, all had ballooning degeneration, four (26.7%) had mild and three (20%) moderate interface hepatitis, four (26.7%) mild lymphoplasmacytic infiltrate, one (6.7%) rosette formation, bridging necrosis in none and stage 1 fibrosis in one. Comparing NAEH with AIH, AIH showed significantly older age at presentation, female predisposition, past history of jaundice, lower ALT, more autoantibodies, higher IgG, higher grade interface hepatitis, lymphoplasmacytic infiltrate, rosette formation and higher bilirubin, AST at three months. NAEH and viral hepatitis had similar features. CONCLUSION: Etiology of NAEH is unlikely to be autoimmune and is probably viral, unidentified as yet. Uncomplicated NAEH likely has self-limiting course even without specific treatment.

INTRODUCTION: An Epiploic Hernia is an extremely rare type of abdominal hernia with <0.1 % incidence where the bowel or other intra-abdominal contents herniate through the Foramen of Winslow. A case of an Epiploic hernia in a middle-aged female is presented here. PRESENTATION OF CASE: A woman in her 60s was admitted to a tertiary level hospital with severe right sided intermittent upper abdominal pain associated with nausea, bloating and constipation. The symptoms were thought to be due to biliary colic and managed conservatively. Since the symptoms persisted and a computed tomography scan of abdomen was organized. CT scan showed that the caecum was in the upper left quadrant. A laparoscopy was performed and demonstrated that her right colon was mobile herniating through the Foramen of Winslow into the lesser sac. The hernia was reduced, and the bowel was viable. The patient was discharged with no complications. DISCUSSION: There have been case reports of small bowel as the content of the hernia with lesser occurrences of caecum, ascending colon, transverse colon, gall bladder, omentum, or Meckel's diverticulum. A caecal herniation through the Foramen of Winslow is reported only with an incidence of 0.02 %. <10 % of these Epiploic hernias are diagnosed preoperatively making it a potentially life-threatening condition if not treated promptly due to high risk of bowel strangulation and mortality of up to 50 %. CONCLUSION: A high index of suspicion is needed for the diagnosis of this internal hernia and radiological investigation is fundamental in making this diagnosis for allowing prompt surgical treatment.
RESUMO
BACKGROUND: The COVID-19 pandemic has affected the healthcare systems worldwide since the dawn of 2020. In March 2020, the United Kingdom government announced the first national lockdown which severely disturbed all National Health Service (NHS) healthcare elective services. Our aim is to assess the long-term impact of COVID-19 related disruption of NHS elective services on emergency major lower limb amputations (MLLAs). METHODS: Patients' data for emergency MLLA for critical limb-threatening ischemia and diabetic foot infections performed at Aberdeen Royal Infirmary was collected through Trakcare and divided into the control prepandemic group (April 2018-March 2020) and the pandemic group (April 2020-March 2022). The statistical analysis was conducted using the IBM SPSS software (v28.0.1.1 [14]). RESULTS: A total of 358 patients underwent MLLA and 206 (57.5%) of these had diabetes mellitus. There was a 17% increase in the number of urgent referrals and every 1 in 5 of these finally underwent an amputation. There was an increase in the absolute number of Above- and Below-Knee amputations. There was a statistically significant increase by 33% in emergency MLLAs during the pandemic period (P < 0.05). A total of 165 postoperative deaths up to December 2022 were recorded with 30-day mortality rate of 7.26% (n = 26). CONCLUSIONS: NHS vascular management groups should update themselves with evolving technologies to optimize the care provided during future unprecedented times. Furthermore, more effective measures should also be implemented to avoid delayed presentations, which can potentially lead to higher rates of major limb amputations.

OBJECTIVES: Tofacitinib is a Janus Kinase inhibitor used for treating moderate to severe ulcerative colitis (UC), mainly after the failure of biological therapy. There is a paucity of data on the outcome of tofacitinib in biological-naïve UC patients. The present study was aimed at analyzing the safety and efficacy of tofacitinib in biological-naïve Indian patients with UC. METHODS: The present study retrospectively evaluated consecutive patients with biological-naïve moderate-to-severe active UC from six tertiary care centers in India receiving tofacitinib from September 2020 to September 2022. Clinical remission or response assessment was based on partial Mayo score (PMS) calculated at baseline and weeks eight, 16 and 24. RESULTS: Total 47 cases (57.4% male, median age: 32 years) were included. After eight weeks of therapy, 33 (70.2%) achieved clinical remission and eight (17.0%) had a primary failure. The baseline serum albumin at treatment initiation was the only independent predictor of remission at eight weeks (Odds ratio: 11.560, 95% CI: 1.478 - 90.404), but not at 16 weeks. By 24 weeks, 59.6% (28/47) of the patients were in remission and 29.8% (14/47) had stopped tofacitinib either due to failure (27.6%) or adverse events (AEs) (2.1%). Among the 47 patients, 10 (21.2%) cases developed AEs during follow-up, including two tuberculosis (4.2%), one cytomegalovirus (CMV) colitis (2.1%) and one herpes zoster (2.1%). Four patients with infection required temporary drug discontinuations. One required permanent discontinuation (mania). CONCLUSION: Upfront tofacitinib is effective in biologic-naïve Indian patients with moderate-severe UC. Further randomized studies are required to validate the study findings.

BACKGROUND: Surgical resection is the gold standard treatment for the management of early-stage lung cancer. Several modifiable factors may significantly influence postoperative morbidity and mortality. We examined the outcomes of patients following lung resection based upon preoperative smoking status to quantify the impact on postoperative outcomes. METHODS: Data from consecutive lung resections from January 1, 2012 to June 11, 2021 were included. Biopsies for interstitial lung disease and resections for emphysematous lung or bullae were excluded. Patients were divided into three cohorts: current smokers (those who smoked within 4 weeks of surgery), ex-smokers (those who stopped smoking prior to 4 weeks leading up to surgery), and nonsmokers (those who have never smoked). Patient's preoperative variables, postoperative complications, length of stay, and mortality were examined. RESULTS: A total of 2,426 patients were included in the study. A total of 502 patients (20.7%) were current smokers, 1,445 (59.6%) were ex-smokers and 479 patients (19.7%) nonsmokers. Of those smoking immediately prior to surgery 36.9% developed postoperative complications. Lower respiratory tract infections (18.1%) and prolonged air leak (17.1%), in particular, were significant higher in smokers. 90-day mortality (5.8%) was higher in the current smokers when compared with ex- and nonsmokers (5.3 and 1%, respectively). Median length of hospital stay, readmissions, and cost of hospital stay was also higher in the current smoker cohort. CONCLUSION: Smoking immediately prior to surgery is associated with an increase in morbidity, mortality, and length of stay. Not only does this have a significant individual impact, but it is also associated with a significant financial burden to the National Health Service.

BACKGROUND: Body mass index (BMI) has been shown to be an independent predictor of survival following lung resection surgery. This study aimed to quantify the short- to midterm impact of abnormal BMI on postoperative outcomes. METHODS: Lung resections at a single institution were examined between 2012 and 2021. Patients were divided into low BMI (<18.5), normal/high BMI (18.5-29.9), and obese BMI (>30). Postoperative complications, length of stay, and 30- and 90-day mortality were examined. RESULTS: A total of 2,424 patients were identified. Of these patients, 2.6% (n = 62) had a low BMI, 67.4% (n = 1,634) had a normal/high BMI, and 30.0% (n = 728) had an obese BMI. Overall postoperative complications were higher in the low BMI group (43.5%) when compared with normal/high (30.9%) and obese BMI group (24.3%) (p = 0.0002). Median length of stay was significantly higher in the low BMI group (8.3 days) compared with 5.2 days in the normal/high and obese BMI groups (p < 0.0001). Ninety-day mortality was higher in the low (16.1%) compared with the normal/high (4.5%) and obese BMI groups (3.7%) (p = 0.0006). Subgroup analysis of the obese cohort did not elucidate any statistically significant differences in overall complications in the morbidly obese. Multivariate analysis determined that BMI is an independent predictor of reduced postoperative complications (odds ratio [OR], 0.96; 95% confidence interval [CI], 0.94-0.97; p < 0.0001) and 90-day mortality (OR, 0.96; 95% CI, 0.92-0.99; p = 0.02). CONCLUSION: Low BMI is associated with significantly worse postoperative outcomes and an approximate fourfold increase in mortality. In our cohort, obesity is associated with reduced morbidity and mortality following lung resection surgery, confirming the existence of the obesity paradox.
RESUMO
Psoralea corylifolia Linn (Bakuchi or Babchi), commonly known as purple fleabane, is a popular herb used in Ayurvedic traditional medicine. Its seeds, called Fructus Psoraleae, are traditionally used for treating leprosy, vitiligo, and psoriasis in the absence of empirical evidence. We report the first case of acute on chronic liver failure (ACLF) caused by Bakuchi, a well-documented hepatotoxic agent, in a middle-aged female. Her liver function deteriorated progressively which prompted us to go for a liver biopsy which was consistent with diagnosis of herb-induced liver injury after excluding all competing causes. Fortunately, the patient improved gradually after herb withdrawal and supportive care. Patients with underlying chronic liver disease (CLD) should be aware of risks in using untested herbal formulations. This case emphasizes the need for increased surveillance to formulate guidelines regarding the regulation and informed use of herbal supplements in patients with chronic liver disease.
RESUMO
Colonic lipomas are benign adipose tumors and are mostly asymptomatic. They may cause symptoms when their size becomes more than 2 cm. Giant colonic lipoma (GCL) is a rare finding in endoscopy which presents with or without macroscopic ulceration and may lead to iron deficiency anaemia (IDA). The choice of treatment of symptomatic large colonic lipomas has been controversial. Here we are presenting a case of GCL presenting with occult bleeding causing iron deficiency anaemia (IDA). It was removed endoscopically using a combination of noradrenaline, endoloop ligation, and snare cautery technique (modified hybrid technique). Successful removal of the GCL lead to the resolution of IDA. This case report highlights that even GCL can be removed endoscopically, thus surgery can be prevented. Clinical Significance: GCL is an unusual cause of anemia. Modified hybrid endoscopic removal technique improves safety.
RESUMO
Crigler-Najjar is a rare genetic autosomal recessive disorder caused by deficiency of enzyme Uridine 5-Diphosphate Glucuronosyl Transferase (UDP-GT). We report the case of a 24-year-old female with two consecutive pregnancies with a high level of total bilirubin level of 15.1 mg/dl and a direct bilirubin level of 0.8 mg/dl during the first pregnancy. As she was diagnosed case of Crigler Najjar type 2, she was on phenobarbitone 60 mg daily. With careful monitoring, she continued with the same dose. We concluded that even with high bilirubin level (15.1 mg/dl) in pregnancy, no adverse effects to the baby and mother were seen.
RESUMO
Background: Acute kidney injury (AKI) occurs in 20-50% of patients with cirrhosis and is associated with a poor prognosis. The aim of the study is to identify the baseline factors affecting mortality in these patients at 30 and 90 days. Methods: We enrolled 117 patients with cirrhosis and AKI and followed them up prospectively. Results: Distribution of International club of ascites AKI stages was: 26 (22.03%) stage 1, 59 (50%) stage 2, and 33 (28%) stage 3. Mortalities at 30 and 90 days were 27 (22.8%) and 33 (27.9%) respectively. On multivariate analysis, variables affecting mortality at 30 days were serum creatinine level>2 mg% at 48 hours after AKI development (adjusted OR 7.93, P=0.02) and leukocytosis (total leucocyte count>11000/mm3 ) at admission (adjusted OR 6.54, P=0.002). Only leukocytosis at admission was a predictor of 90 days mortality (adjusted OR 4.76, P=0.01). Though not statistically significant, patients not responding to standard medical treatment had 3 times higher mortality at 30 days, while the maximum AKI stages (2 and 3) had eight times higher mortality at 90 days. Conclusion: In cirrhosis, AKI increases short-term mortality. High serum creatinine at 48 hours affects mortality at 30 days, while leukocytosis at baseline predicts mortality at 30 and 90 days. Progression to a higher AKI stage impacts prognosis.
RESUMO
Background: Hepatocellular carcinoma (HCC) is asymptomatic at an early stage which delays its timely diagnosis and treatment. Circulating tumor cells (CTCs), derived from a primary or secondary tumor, may help in the management of HCC. Here, we evaluate and characterize CTCs in liver disease patients. Methods: In total, 65 patients, categorized into liver cirrhosis (LC) (n = 30) and HCC (n = 35), were enrolled. Using ImagestreamX MkII imaging flow cytometer, CTCs were detected and characterized using biomarker expression of EpCAM, CK, AFP, CD45, and DRAQ5 in LC and HCC patients. Results: CTCs were detected in 33/35 (94%) HCC patients and in 28/30 (93%) LC patients. In the HCC group, the number of biomarker-positive CTCs was higher in BCLC stage D when compared with others. EpCAM + CK was the most expressed biomarker on CTCs in LC versus HCC (83.3% vs. 77.14%), followed by AFP (80% vs. 65.71%), EpCAM (30% vs. 28.57%), and CK (16.6% vs. 14.28%). The EpCAM cell area was significantly associated (P value = 0.031) with the CTC-positive status. The combination biomarker expression of CTCs cell area (EpCAM, CK, and AFP) performed well with the area under the curve of 0.92, high sensitivity, and specificity in detecting early-stage and AFP-negative HCC as well as in AFP-negative LC cases. Conclusion: Enumeration and cell area of CTCs may be used as a biomarker for early detection of HCC and guiding treatment.
RESUMO
INTRODUCTION: Electrosurgical unit (ESU) is integral to the endoscopy unit. The proper knowledge of the Mode with setting is essential for good therapeutic outcomes and the safety of the patients. AREAS COVERED: ESU generates high-frequency electric current, which could perform cutting and coagulation for various therapeutic interventions. We review the proper settings for common endoscopic interventions like hemostasis, polypectomy, sphincterotomy, and advanced procedures like endoscopic ultrasound-guided cysto-gastrostomy, bile duct drainage, and endoscopic Ampullectomy. We review the various waveforms of ESU in practice in endoscopy, including special conditions like patients with pacemakers. EXPERT OPINION: Knowledge of the waveforms' duty cycle and crest factor is necessary. A high-duty cycle and lower crest factor lead to a good cutting effect on the tissue. Endocut is the most commonly used Mode in ESU in endoscopic practices like sphincterotomy and polypectomy. Endocut I mode (effect 1-2, duration 3, interval 3) is used for endoscopic sphincterotomy, while Forced Coag mode (Effect 2, 60 W) controls post-sphincterotomy bleeding. Endocut Q mode (Effect 2-3, duration 1, interval 3) is used for cutting the polyp, while Forced Coag mode (Effect 2, 60 W) is used before cutting for pre-coagulation of the stalk.
