Abstract
Synthesizing nanoparticles through a green synthesis approach is common nowadays. Cyanobacteria have attained great importance in the field of biosynthesis of nanoparticles as there is no use of toxic chemicals as reducing or capping agents for the synthesis of metal oxide nanoparticles. Micronutrient-based nano-formulations have become a topic of great interest in recent times due to their various advantageous properties and applications in agriculture. The current study aims to exploit the potential cyanobacterial strains isolated from different locations such as freshwater and soil ecosystems. The potential cyanobacterial isolates were screened based on their multiple plant growth promoting (PGP) attributes such as Indol acetic acid (IAA) production, siderophores, and phosphate solubilization. After the screening of cyanobacteria based on multiple PGP activities, the cyanobacterial strain was identified at the species level as Pseudanabaena foetida RJ1, based on microscopy and molecular characterization using 16S rRNA gene sequencing. The cyanobacterial biomass extract and cell-free extracts are utilized for the synthesis of CuO micronutrient Nanoparticles (NPs). The cyanobacterial strain Pseudanabaena foetida RJ1 possesses plant growth-promoting (PGP) attributes that provide reduction and capping for CuO NPs. The synthesized NPs were characterized and subjected to make a nano-formulation, utilizing the cyanobacteria-mediated CuO NPs along with low-cost zeolite as an adsorbent. The application of cyanobacterial biomass extract and cell-free extract provided an excellent comparative aspect in terms of micronutrient NP synthesis. The NPs in the form of formulations were applied to germinated paddy seeds (Pusa Basmati -1509) with varying concentrations (5, 10, 15 mg/l). Effects of cyanobacteria based CuO NPs on hydroponically grown paddy crops were analyzed. The application of nano-formulations has shown a significant increase in plant growth promotion in rice plants under hydroponics conditions. There is no such type of comparative investigation reported earlier, and NPs of micronutrients can be utilized as a new economic nanofertilizer and can be applied to plants for their growth promotion.

Abstract
BACKGROUND Perivascular epithelioid cell tumors (PEComas) encompass a group of rare mesenchymal neoplasms, with dual melanocytic and muscular differentiation. Hepatic PEComas are rare and difficult to diagnose, and their behavior is still unclear. MATERIALS AND METHODS Herein, we report a total of five cases of hepatic and perihepatic PEComas over a period of the last 5 years from our and collaborating center's archive. A detailed histological evaluation was done. A comprehensive panel of immunohistochemical stains was used and fluorescence in-situ hybridization analysis was performed for the TFE3 gene using break-apart probes. RESULT All these patients were women, with an average age of presentation of 44 years. The lesions were in the right hepatic lobe: three cases, the left hepatic lobe: one case, and gastrohepatic ligament: one case. The preoperative clinicoradiological diagnoses were hepatocellular carcinoma (HCC), focal nodular hyperplasia, hemangioma, metastasis, and gastrointestinal stromal tumor, respectively. Surgical excision was performed in four cases with no further adjuvant therapy. Histopathological examination and subsequent immunophenotyping revealed a diagnosis of PEComa. Fluorescence in-situ hybridization analysis was performed for TFE3 gene rearrangement in four cases. CONCLUSIONS This series highlights the fact that accurate histological diagnosis of hepatic or perihepatic PEComas is important to prevent unnecessary aggressive treatment, unlike primary hepatocellular carcinomas or hepatoid/epithelioid metastatic tumors.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is an emerging global health problem and a potential risk factor for metabolic diseases. The bidirectional interactions between liver and gut made dysbiotic gut microbiome one of the key risk factors for NAFLD. In this study, we reported an increased abundance of Collinsella aerofaciens in the gut of obese and NASH patients living in India. We isolated C. aerofaciens from the fecal samples of biopsy-proven NASH patients and observed that their genome is enriched with carbohydrate metabolism, fatty acid biosynthesis, and pro-inflammatory functions and have the potency to increase ethanol level in blood. An animal study indicated that mice supplemented with C. aerofaciens had increased levels of circulatory ethanol, high levels of hepatic hydroxyproline, triglyceride, and inflammation in the liver. The present findings indicate that perturbation in the gut microbiome composition is a key risk factor for NAFLD.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver malignancy in adults occurring in a background of cirrhosis. Peritoneal dissemination of HCC is an unusual presentation with an incidence of 2%-16%. Peritoneal metastasis of an unruptured HCC is extremely uncommon. Despite low yield, ascitic fluid cytology serves as a valuable tool for diagnostic evaluation in a patient of cirrhosis with suspicion of malignant transformation. We present a rare case scenario in an elderly female with cirrhosis where the diagnosis of peritoneal metastasis was established on ascitic fluid cytology and confirmed by immunocytochemistry. This report illustrates the unique clinical presentation of an unruptured HCC with its cytological features and a brief review of literature.

Abstract
BACKGROUND Aberrant crypt foci (ACF) are the earliest preneoplastic lesions in human colon, identifiable on chromoendoscopic screening. Our objective was to evaluate the %methylation of APC, CDKN2A, MLH1, RASSF1, MGMT, and WIF1 tumor suppressor genes (TSG) in ACF, corresponding colorectal carcinomas (CRC), and normal colonic mucosal controls. METHODS In this study, macroscopically normal-appearing mucosal flaps were sampled 5-10 cm away from the tumor mass from 302 fresh colectomy specimens to identify ACF-like lesions. Thirty-five cases with multiple ACFs were selected (n 35) as the main study group, with corresponding sections from CRC (n 35) as disease controls, and mucosal tissue blocks from 20 colectomy specimens (normal controls), operated for non-neoplastic pathologies. Genomic DNA was extracted, and methylation-specific polymerase chain reaction (PCR) was performed on a customized methylation array model. %Methylation data were compared among the groups and with clinicopathological parameters. Selected target mRNA and protein expression studies were performed. RESULTS %Methylation of TSGs in ACF was intermediate between normal colon and CRC, although a statistically significant difference was observed only for the WIF1 gene (P < 0.01). Also, there was increased nuclear β-catenin expression and upregulation of CD44-positive cancer-stem cells in ACF and CRCs than in controls. Right-sided ACFs and dysplastic ACFs had a higher %methylation of CDKN2A (P < 0.01), whereas hyperplastic ACFs had a higher %methylation of RASSF1 (P 0.04). The topographic characteristics of ACFs did not correlate with TSG %methylation. CONCLUSIONS Early epigenetic methylation of WIF1 gene is one of the mechanisms for ACF development in human colon.

Abstract
BACKGROUND Non-invasive tests (NITs) are useful to assess advanced fibrosis (AF) in nonalcoholic fatty liver disease (NAFLD). Data from Asian countries suggest that these tests have poor performance. We aimed to assess diagnostic accuracy of established thresholds of biomarker-based NITs and Transient Elastography (TE) in identifying AF and evaluated the utility of a two-step test approach. METHODS Biopsy-proven 641 NAFLD patients (55.2% males, median age 42 years) were included from three different centers of Asia. AF (≥ F3) was identified as per histological staging (24.8%). RESULTS TE had the highest area under the receiver operating characteristic curve (AUROC) 0.82 (0.79-0.86), and all other biomarker-based NITs had low AUROC (< 0.7). NITs performed poorly at established thresholds. The combination of NITs utilizing liver stiffness measurement (LSM) and biomarkers, Agile 3+ and FAST, demonstrated acceptable diagnostic accuracy (AUROC 0.82 and 0.78, respectively), but none were superior to LSM alone. LSM measured using appropriate M and XL probes remained accurate regardless of body mass index (BMI); NFS and APRI scores were less accurate at higher BMI ranges. A two-step approach using NFS rule-out criteria (< - 2.97 to rule out) followed by LSM (< 7.3 kPa to rule out and ≥ 12.7 kPa to rule in) correctly classified 62.4% of patients, with only 10.2% of patients incorrectly classified. CONCLUSION NITs have not been validated to identify AF in the Asian NAFLD population, and internationally accepted thresholds yield high false-negative rates. LSM and LSM-based combination tests remain the most accurate.

Abstract
Diabetes is associated with a greater number of dental cavities. It is unclear, therefore, how potential risk factors such as salivary glucose, glycemic control and blood sugar could impact the onset of dental caries between people that have type 2 diabetes (T2D). Aim of the study - analyzing the risk factors for oral cavity disease in T2D patients. We analyzed the patient data including their dietary habits, dental hygiene practices, age and control of glycemic. The Indian dataset was used. Individual patient observations include the patient's diabetes classification as a range of medical attributes such as age, pregnancy, pedigree, glucose, body mass index, skin, blood pressure and insulin. The research discovered a significant correlation between poorly managed glycemic levels and dental caries are more prevalent in people with T2DM. High sugar consumption and poor oral hygiene habits have been identified as risk factors. These results highlight the need for integrating diabetes treatment measures with dental care to reduce dental caries in this susceptible group. Utilizing dental cavities into account improves oral health and has a positive impact on health outcomes for those with type 2 diabetes.

Abstract
OBJECTIVE: To examine the short-term effect of ambient air pollution on daily acute respiratory emergency room visits among adults.METHODS: A time-series study (June 2017-February 2019) was carried out among adults (≥18 years) visiting a multi-specialty hospital in Delhi. We evaluated the association between the daily levels of particulate matter (PM) <2.5 μm in diameter (PM2.5) and PM <10 μm in diameter (PM10), ozone (O₃), nitrogen dioxide (NO₂), carbon monoxide (CO) and sulphur dioxide and daily count of emergency room (ER) visits for acute respiratory symptoms. Generalised additive model (GAM) was used with the Poisson link function to analyse the associations for 0-1 to 0-7 lag days.RESULTS: A total of 69,400 ER visits were recorded, of which 2,669 were by adults due to acute respiratory symptoms. At 0-7 lag days, an increment of 1 standard deviation in NO₂ and PM2.5 concentration was associated with a percentage increase in acute respiratory ER visits of respectively 53.0% (95% CI 30.84-78.97) and 19.5% (95% CI 4.53-36.65). During 0-7 lag days, a positive trend was observed at higher concentrations of CO (>1.86-3.28 mg/m³), while a negative significant association was observed at low concentrations of CO (<1.171 mg/m³).CONCLUSION: Short-term exposure to ambient NO2 and PM2.5 was associated with acute respiratory emergency visits of adults at lag 0-7 days.

Abstract
Resistance to therapy in esophageal squamous cell carcinoma (ESCC) is a critical clinical problem and identification of novel therapeutic targets is highly warranted. Dipeptidyl peptidase III (DPP3) is a zinc-dependent aminopeptidase and functions in the terminal stages of the protein turnover. Several studies have reported overexpression and oncogenic functions of DPP3 in numerous malignancies. The present study aimed to determine the expression pattern and functional role of DPP3 in ESCC. DPP3 expression was assessed in normal and tumor tissues using quantitative real-time (qRT)-PCR and corroborated with ESCC gene expression datasets from Gene Expression Omnibus (GEO) and The cancer genome atlas (TCGA). DPP3 stable knockdown was performed in ESCC cells by shRNA and its effect on cell proliferation, migration, cell cycle, apoptosis, and activation of nuclear factor erythroid 2-related factor 2 (NRF2) pathway was assessed. The results suggested that DPP3 is overexpressed in ESCC and its knockdown leads to reduced proliferation, increased apoptosis, and inhibited migration of ESCC cells. Additionally, DPP3 knockdown leads to down-regulation of the NRF2 pathway proteins, such as NRF2, G6PD, and NQO1 along with increased sensitivity toward oxidative stress-induced cell death and chemotherapy. Conclusively, these results demonstrate critical role of DPP3 in ESCC and DPP3/NRF2 axis may serve as an attractive therapeutic target against chemoresistance in this malignancy.

Abstract
BACKGROUND The relationship between body mass index (BMI) and outcomes in patients with nonalcoholic fatty liver disease (NAFLD) is not well defined. This study aimed to assess the presentations, outcomes, and development of liver-related events (LREs) and non-LREs in patients with NAFLD stratified by BMI. METHODS Records of NAFLD patients from 2000-2022 were reviewed. Patients were categorized as lean (18.5-22.9 kg/m2), overweight (23-24.9 kg/m2), and obese (>25 kg/m2) based on BMI. Stage of steatosis, fibrosis, and NAFLD activity score were noted in the patients undergoing liver biopsy in each group. RESULTS Out of 1051 NAFLD patients, 127 (12.1%) had normal BMI, 177 (16.8%) and 747 (71.1%) were overweight and obese, respectively. Median [interquartile range] BMI was 21.9 [20.6-22.5], 24.2 [23.7-24.6], and 28.3 [26.6-30.6] kg/m2 in each group, respectively. Prevalence of metabolic syndrome and dyslipidemia were significantly higher in the obese. Obese patients had significantly higher median [interquartile range] liver stiffness (6.4 [4.9-9.4] kPa) than overweight and lean subjects. A higher proportion of obese patients had significant and advanced liver fibrosis. At follow-up, there were no significant differences in the progression of liver disease, new LREs, coronary artery disease, or hypertension across the BMI groups. Overweight and obese patients were more likely to develop new-onset diabetes by follow-up. The mortality rates in the three groups were comparable (0.47, 0.68, and 0.49 per 100 person-years, respectively), with similar causes of death (liver-related vs non-liver-related). CONCLUSIONS Patients with lean NAFLD have similar disease severity and rates of progression as the obese. BMI is not a reliable determinant of outcomes in NAFLD patients. KEY MESSAGES

Abstract
Effect of Bis-2ethylhexyl phthalate (DEHP) on commercially important tropical fish pearl spot has not been demonstrated at environmental concentrations along with depuration. The species is estuarine, juvenile and difficult to maintain but widely consumed and well distributed in tropical estuaries. Antioxidant activity of SOD, CAT and GPx was enhanced on all exposure days for gill and muscle suggesting high oxidative stress, except on day 5. Detoxifying enzyme-GST behaved differentially in gill and muscle tissue after depuration, depicting inhibited activity of GST in gill leading to lipid peroxidation. However, the muscle tissue was able to recover from stress after 7 days of depuration with the help of detoxifying enzymes. Overcompensation of antioxidant activity was observed over disruption of homeostasis defining hormesis effect. Integrated biomarker (IBR) index depicted high toxicity during entire exposure time, but after depuration, gill could not mediate LPO at lowest concentration (10 μg/l) while muscle tissue recovered, suggesting persistence of stress in gill.

Abstract
INTRODUCTION Hepatocellular carcinoma (HCC) is a common primary malignancy of the liver but is rare in the paediatric age group; thus, it may be misdiagnosed as the more common tumour, hepatoblastoma. Management varies in both these tumours, and pathological diagnosis thus plays an important role for definitive therapy. Only a few case reports available in the literature have described the cytological characteristics of paediatric HCC. The present study was thus planned to evaluate the cytomorphological features of paediatric HCC. METHODS Cases diagnosed with HCC on ultrasound-guided fine needle aspiration cytology over a period of 14 years were retrieved. The cases were evaluated for detailed cytological features including cellularity, architecture, sinusoidal wrapping, trabecular thickness, necrosis, anisonucleosis, chromatin, nucleoli, nuclear contours, bi- or multinucleation, intranuclear and intracytoplasmic inclusions, naked nuclei, extra-medullary haematopoiesis, monomorphism, and nuclear overlapping. RESULTS Twelve cases of HCC were included in the study. The median age at diagnosis was 10 years. Serum alpha-fetoprotein level was raised in most of them. Five of the 12 cases were characterised as moderately differentiated, three as poorly differentiated, two as well differentiated, and two as the fibrolamellar type of HCC. Cytohistological correlation was performed in seven cases. CONCLUSIONS Ultrasound-guided fine needle aspiration serves as a useful tool to diagnose paediatric HCC and differentiate it from other primary hepatic malignancies, especially hepatoblastoma which closely mimics HCC in this age group, as serum alpha protein levels and imaging findings are unable to distinguish these two tumours.

Abstract
BACKGROUND Advanced fibrosis and cirrhosis (compensated advanced chronic liver disease [cACLD]) are clinically indistinguishable and increase risk of developing clinically significant portal hypertension. Baveno VII recommends using elastography to rule out and diagnose cACLD with liver stiffness measurement (LSM) cut-offs of 10/15 kPa. METHODS In a retrospective analysis of 330 nonalcoholic fatty liver disease (NAFLD) patients, performance of the Baveno VII cut-offs for diagnosing cACLD was compared with newly suggested lower cut-offs (8/12 kPa). A model for detecting cACLD among those with LSM between 8 and 12 kPa was developed and compared with recently published models. RESULTS Seventy (21.2%) of the 330 NAFLD patients had biopsy-proven cACLD. The Baveno VII cut-offs (10/15 kPa) had a lower sensitivity of 72.8% (60.9-82.8%) and a specificity of 93.4% (89.7-96.1%). Sensitivity and specificity of lower cut-offs (8/12 kPa) were 91.4% (82.3-96.8%) and 88.5% (83.9-92.1%), respectively. Modeling based on the presence of diabetes (odds ratio [OR] 3.625[1.161-11.320], p = 0.027) and serum aspartate aminotransferase (AST) levels (OR 1.636[1.098-2.436], p = 0.015) correctly identified 75.7% of patients with LSM between 8 and 12 kPa. Our model performed best with an area under receiver operator curve (AUROC) of 0.725 (95%CI 0.609-0.822), compared to Papatheodoridi (AUROC 0.626, CI 0.506-.736) and Zhou (AUROC 0.523, CI 0.403-0.640) models. A two-step strategy comprising application of lower LSM cut-offs followed by the predictive model correctly identified the presence of cACLD in 83% of the patients as compared to 75% by the Baveno VII cut-offs. CONCLUSION A two-step strategy employing lower LSM cut-offs and modeling based on diabetes and AST levels outperforms Baveno VII cut-offs for identifying cACLD in NAFLD patients.

Abstract
652 Background: Pancreatic neuroendocrine neoplasms (PanNENs) are rare entities comprising 1-2% of gastroenteropancreatic neoplasms with an annual incidence of 0.48/100,000 population in the world. The molecular pathways underpinning the entity are less explored owing to its rarity. We aimed to analyse and correlate the expression of chromatin remodelers in PanNENs from Indian subcontinent. Methods: An ambispective study (prospective 2014-2018 as well as retrospective 2018-2021) was conducted. Haematoxylin and eosin stained slides with immunohistochemistry slides (chromogranin, synaptophysin) of 73 cases of PanNENs were retrieved from archives of Department of Pathology, AlIMS, New Delhi and evaluated for assessment of histopathological parameters. Following slide review, grading and staging were done based on WHO 2017 Classification and AJCC eighth edition respectively. Representative formalin fixed paraffin embedded block was selected after slide review and retrieved for performing immunohistochemical staining with antibodies against ATRX, DAXX, SETD2, H3K36Me3 and ARID1A using Ultra Vision Quanto polymer detection system by Thermo Fisher Scientific. Data was analysed using STATA version SE14. Results: Study cohort of 73 PanNENs had a mean age of presentation 41 years (Range: 8 years -70 years) and male to female ratio of 1.43:1. Majority of the tumors in our study were non functional (63.01%). Loss of nuclear expression of ATRX/DAXX (at least one marker) was seen in 26/73 (35.62%) cases. Loss of expression had significant correlation with pathological stage of the tumor, presence of distant metastasis and adverse prognostic outcome (p value-<0.05). Lower grade tumors with low to intermediate ki67 index had higher preponderance for loss of expression of ARID1A. Loss of expression of any of the chromatin remodelers (ATRX/DAXX/ARID1A/H3K36Me3) was noted in 44/73 cases (60.27%) and was more frequently associated with advanced stage of tumor or recurrence/metastasis/death (p value-0.005). Conclusions: Loss of chromatin remodelers such as ATRX, DAXX, ARID1A, SETD2 and H3K36ME3 is involved in the pathogenesis of pancreatic neuroendocrine neoplasms and are associated with adverse outcomes, so loss or lower immunohistochemical expression for these can serve as a poor prognostic factor and guide for adjuvant therapy.

Abstract
Background The advent of molecular driver alterations has brought in a revolutionary transformation in the treatment landscape of gastrointestinal stromal tumour (GIST). However, there is a paucity of data regarding mutational testing prevalence and associated outcomes from India. Methods It was a retrospective study. We reviewed the case records of all patients diagnosed with GIST in a tertiary care centre from 2015 to 2021. The clinicopathological, mutational analysis and treatment plans were recorded. The study cohort was characterised by descriptive statistics. Results Our study included 120 patients with a median age of 53 years (range: 28-77), with a male preponderance of 2:1. The most common site of the primary was the stomach (50%), followed by the small intestine (37%), with 55.8% of the patients having disseminated disease at presentation with a predominance of liver metastasis (67%). The prevalence of mutational analysis among patients prior to referral was 4%. 60.8% of the patients at our clinic had mutational analysis performed, and unavailability of analysis in the rest was due to financial constraints (12.5%), exhaustion of tissue (7.5%), reluctance to repeat biopsy (4.1%) and low-risk patients. We report c-kit in the majority (52%), platelet-derived growth factor receptor (PDGFR) in 19.2% and wild type in 16.4% along with the rarer subtypes: succinate dehydrogenase (SDH)-deficient GIST in 10.9% and Neurotrophic tyrosine receptor kinase (NTRK) fusion in 1.3%. Four of the eight SDH-deficient GIST patients had germline mutations (50%). The knowledge of driver mutations led to a change of treatment in 39.7% (29/73), i.e. stoppage of tyrosine kinase inhibitor (TKI) in 3, switch of TKI in 23, increase in TKI dose in 2 and upfront surgery in 1. The most common change was the use of sunitinib and regorafenib in patients with SDH-deficient GIST. Conclusion Our study is one of the largest comprehensive series describing the clinical and mutational profile of GIST from India. The mutation testing rates at primary care centres continue to be low. Despite the hurdles, a large percentage of our patients underwent molecular testing, aiding in therapeutic decision-making.

Abstract
BACKGROUND AND AIMS The role of intestinal-barrier in acute pancreatitis(AP) is poorly understood. We aimed to assess structural and functional changes in the intestinal-barrier in patients with early AP (time from onset<2 weeks) and the effect of enteral nutrition on them. METHODS In this prospective observational study, patients with early AP not on enteral nutrition were compared with controls for baseline intestinal-permeability(lactulose: mannitol ratio(L:M)), endotoxinemia(serum IgM/IgG anti-endotoxin antibodies), bacterial-translocation(serum bacterial 16S rRNA) and duodenal epithelial tight-junction structure by immunohistochemistry(IHC) for tight-junction proteins(claudin-2,-3,-4, zonula occludens-1(ZO1), junctional adhesion molecule(JAM) and occludin) and electron microscopy. These parameters were reassessed after 2 weeks enteral feeding in a AP patients subset. RESULTS 96 patients with AP(age: 38.0 ± 14.5 years; etiology: biliary[46.8%]/alcohol[39.6%]; severe:53.2%, mortality:11.4%) and 40 matched controls were recruited. Patients with AP had higher baseline intestinal permeability(median L:M 0.176(IQR 0.073-0.376) vs 0.049(0.024-0.075) in controls; p < 0.001) and more frequent bacteraemia(positive bacterial 16S rRNA in 24/48 AP vs 0/21 controls; p < 0.001) with trend towards higher serum endotoxinemia(median IgG anti-endotoxin 78(51.2-171.6) GMU/ml vs 51.2(26.16-79.2) in controls; p = 0.061). Claudin-2, claudin-3, ZO1 were downregulated in both duodenal crypts and villi while claudin-4 and JAM were downregulated in duodenal villi and crypts respectively. 22 AP patients reassessed after initiation of enteral nutrition showed trend towards improving intestinal permeability, serum endotoxinemia and bacteraemia, with significant improvement in claudin-2,-3 in duodenal villi. CONCLUSION Patients with AP have significant disturbances in intestinal barrier structure and function in first 2 weeks from onset that persist despite institution of enteral nutrition.

Abstract
Castleman disease (CD) is a rare benign disorder presents as a lymph nodal mass in mediastinum, cervical, axillary or abdomen. Due to the presence of dysplastic dendritic cell in a background mature lymphocyte and plasma cell, it mimics Hodgkin disease (HD). Synchronous and metachronous occurrence in HD and CD can also occur. An 11-year-old male presented with cervical lymphadenopathy (3.5 × 3.5 cm). Fine needle aspiration shows atypical binucleate cell in a background of small lymphocytes, a diagnosis of Hodgkin disease is suggested. Excisional biopsy showed classical features of Hyaline vascular Castleman disease. Careful cytological evaluation and clinical correlation is required for definitive diagnosis.

Abstract
Aim Hemangioendotheliomas (HEs) are malignant vascular tumors with sparse descriptions in literature owing to their rarity. Study design Ours is a retrospective study among patients of advanced HEs registered between September 2015 and April 2021. Results There were 13 patients with median age 34.6 (range: 4-69 years), male preponderance (69%) and predominant subtype of epithelioid HE (76.9%). Common primary sites were viscera (46.2%) and bone (30.8%). Tyrosine kinase inhibitors (TKIs) yielded objective responses in 30% patients whereas chemotherapy only produced disease stabilization in 7.7%. Conclusion We recognize an aggressive subset of HEs with manifestations such as acute liver failure and splenic rupture. Currently no biomarkers predict the efficacy of TKIs over chemotherapy; however, TKIs showed promising outcomes in this series.

Abstract
BACKGROUND H. pylori-associated gastritis in patients from the high-altitude area of Ladakh showed severe gastritis, mucosal nodularity, atrophy, and cancer in comparison to those from North India. This study served to analyze if differences in the H. pylori virulence genotypes decide the extent of gastric mucosal inflammation. METHODS Fifty gastric biopsies each from patients with H. pylori-associated gastritis from Ladakh and a tertiary care center in North India were included. The presence of H. pylori strain was confirmed with Warthin starry stain and polymerase chain amplification of the H. pylori-specific 16S rRNA. The cagA, vacA s1, s2, and m1, m2 alleles, and dupA virulence genotypes were studied in all archival samples, followed by their histological correlations. RESULTS cagA (P 0.009) and vacAs1 m1 (P 0.009) genes were distinctly more in H. pylori strains colonizing the biopsies of North Indian patients. In contrast, the cagA -ve vacAs2 m2 strains were significantly more in H. pylori strain colonizing the biopsies from Ladakhi patients. dupA genotype was almost similarly present in strains from both regions. Among these, only cagA and dupA virulence genes were associated with severe mucosal neutrophilic activity and deep infiltration of H. pylori strains in North Indian patients. CONCLUSIONS Differences in virulence genotypes of H. pylori in gastric biopsies from North Indian and Ladakhi patients were found not significant in deciding the severity of H. pylori-associated gastritis.

Abstract
OBJECTIVE Although the elderly population remains at high risk for tuberculosis, studies addressing tuberculous meningitis (TBM) in this age group are scarce. The present study aimed to evaluate the spectrum and outcome of geriatric TBM and document differences between older and young patients. METHODS A prospective cohort study was conducted in the adult TBM patients admitted at PGIMER, Chandigarh (India). Consecutive older patients aged 60 years and above were enrolled from January 2019 to December 2020, and young adults aged 18-59 years were enrolled from July 2019 to December 2019. RESULTS Fifty-five older patients with a mean age of 66.6 years and 73 young patients with a mean age of 35.1 years were enrolled. At admission, older patients were more likely to have altered mental status (96.4% vs. 78.1%, P = 0.003) and advanced disease with British medical research council staging 2 or 3 (98.2% vs. 89.0%, P = 0.043); however, headache (38.2% vs. 67.1%, P = 0.001), vomiting (18.2% vs. 35.6%, P = 0.030) and fever (80.0% vs. 91.8%, P = 0.052) were less common. Cerebrospinal fluid (CSF) abnormalities were less marked in older patients, with a significant difference in median total cells (70 vs. 110/µl, P = 0.013). Hydrocephalous and infarct were common neuroimaging abnormalities in both groups; however, tuberculomas were significantly less in the elderly (15.1% vs. 35.2%, P = 0.012). Older patients had a significantly low survival rate (56.4% vs. 76.7%, P = 0.021). CONCLUSION Significant differences in clinical, CSF and radiological characteristics exist between elderly and young TBM patients, with survival remains dismal in the elderly.

Abstract
Progressive multifocal leukoencephalopathy (PML) is a rare demyelinating central nervous system illness encountered in the setting of immunosuppressive conditions like human immunodeficiency virus / acquired immunodeficiency syndrome, autoimmune diseases and hematologic malignancies. We had a 54-year-old woman with systemic lupus erythematosus and coexisting autoimmune hepatitis who presented with progressive cognitive decline, right hemiparesis and ataxia who was found to have PML. She had severe CD4 lymphopenia. She was managed with low-dose prednisolone and plasma exchange after which she showed significant clinical improvement. This case highlights the diagnostic and therapeutic challenges encountered in managing a case of PML in the setting of autoimmune conditions with profound lymphopenia.

Abstract
AbstractCronkhite–Canada syndrome is a rare non-hereditary disease characterized by gastrointestinal hamartomatous polyposis and protein-losing enteropathy. The presenting symptoms are onychodystrophy, skin pigmentation, alopecia, weight loss, and diarrhea. Diagnosis is suggested by a combination of clinical, imaging, and endoscopy findings, and histology is necessary for confirmation. Here we describe a case of a 54-year-old man presenting with watery diarrhea, colicky abdominal pain, nasal obstruction, and weight loss for 6 months. Endoscopy showed multiple polyps in the stomach, duodenum, and colon. These were seen on computed tomography (CT) enterography along with polyps in the small bowel. A final diagnosis was made after the biopsy.

Abstract
BACKGROUND Tight junction proteins (TJPs) play an important role in gut-barrier dysfunction in cirrhosis and its complications such as acute variceal bleed (AVB). However, the dynamics of TJPs expression after AVB, its relation to bacterial translocation, and impact on clinical outcome is largely unknown. AIMS The aim of this study was to study the expression of TJPs in cirrhosis and assess its dynamic changes in AVB. In addition, the relation of TJP expression to endotoxemia and clinical outcomes was assessed. METHODS In this prospective pilot study, 17 patients of cirrhosis with AVB, 59 patients of cirrhosis without AVB (non-AVB cirrhosis), and 20 controls were assessed for claudin-2 and claudin-4 expression in the duodenal biopsy. In the AVB-cirrhosis group, additional biopsies were obtained after 3 weeks. Endotoxemia was assessed by measuring IgG anti-endotoxin antibody levels. Claudin expression was correlated with a 6-month survival. RESULTS Claudin-2 expression was downregulated in patients with AVB and non-AVB cirrhosis in villi (P < 0.001 and 0.013) and crypts (P < 0.001 and 0.012), respectively, compared with the controls. Claudin-4 expression was similar in villi (P = 0.079), but lower in crypts (P = 0.007) in patients with cirrhosis. Claudin-2 expression was upregulated on serial biopsies in both villi and crypts (P = 0.003 and 0.001, respectively) in AVB-cirrhosis with postbleed expression comparable with those with non-AVB cirrhosis. IgG anti-endotoxin antibody levels were elevated in cirrhosis with no correlation with claudin-2/4 expression. Claudin-2 expression independently predicted survival at 6 months. CONCLUSION Both claudin-2 and claudin-4 expression are downregulated in cirrhosis. AVB is associated with dynamic changes in TJPs expression. Gut-barrier dysfunction might predict outcomes independent of bacterial endotoxemia in cirrhosis.

Abstract
Background Recent SIOPEL studies have shown cisplatin monotherapy to be equally effective in management of Standard risk Hepatoblastoma (SRHB)as compared to PLADO. Aims and Objectives To study the chemotherapy, response and outcomes in children with SRHB. Material and Methods A retrospective study was conducted and all children with SRHB who presented to us from June 2007 to December 2017 were included. All patients with standard risk hepatoblastoma who had received at least 2 cycles of chemotherapy were included. Data regarding the demographics, PRETEXT stage, chemotherapy, response to chemotherapy and outcomes were recorded. Kaplan Meier survival analysis was performed to calculate 5 year overall survival (OS) and event free survival (EFS). Results Thirty two children were included in the study. The disease was PRETEXT I in 5 (15.6%), II in 9 (28.1%) and 18 (56.2%). Nineteen children (59.4%) received Cisplatin monotherapy and of these 6 patients (all PREXT III) had poor response and the chemotherapy was upgraded to PLADO. The remaining 13 (40.6%) received upfront PLADO chemotherapy. Only 31 patients could be operated. Tumor recurred in 5 patients, 2 who had upfront PLADO and 3 patients had been upgraded to PLADO. The 5 year OS and EFS was 100% in the monotherapy group (n=13), 92% and 69% in the upfront PLADO group (n=13), and 62% and 22% in the upgraded to PLADO group (n=6). Patients with PRETEXT III disease in whom chemotherapy was upgraded to PLADO had significantly lower survival (p=0.036) compared to those who received upfront PLADO chemotherapy. Conclusion Two thirds of patients with PRETEXT stage III who received cisplatin monotherapy showed poor response and were upgraded to PLADO chemotherapy. These patients had a significantly poorer outcome compared to the rest of the cohort. PRETEXT stage III standard-risk hepatoblastoma may benefit from PLADO chemotherapy instead of cisplatin monotherapy.

Abstract
Background Differentiation of neonatal cholestasis into neonatal hepatitis (NH) and extrahepatic biliary atresia (EHBA) is essential to formulate the treatment plan; promptness is indispensable for optimal outcomes. The clinical and nonoperative algorithms lack precision; the gold standard investigations (liver biopsy or per-operative cholangiogram) are invasive. There is a need for a noninvasive test which is both, sensitive and specific and has a high likelihood ratio. Aim To study the (diagnostic) role of matrix metalloproteinase 7 (MMP-7) as a serum biomarker to differentiate between EHBA and NH and evaluate the prognostic significance in EHBA based on its correlation with liver histopathology and serological predictors of liver fibrosis - Aspartate-to-Platelet Ratio Index (APRI) and Fibrosis-4 (FIB-4). Materials and Methods This was a prospective study conducted upon patients of neonatal cholestasis presenting with acholic stools (n = 46) with equal number of controls (n = 45) with no liver pathology. Observational parametric included disease-specific workup and serum MMP-7 levels (all participants); liver biopsyl and APRI-FIB-4 (EHBA). Results (Diagnostic) Serum MMP-7 levels were significantly elevated in EHBA (n = 25; 28 ng/mL) as compared to those in NH (n = 21; 1.88 ng/mL) and normal infants (n = 45; 1.2 ng/mL) (P < 0.001 for both). Serum cutoff at 4.99 ng/mL differentiated EHBA-NH with a high sensitivity (96%), specificity (90.5%), and a negative predictive value (95%), with the number needed to misdiagnose being 23. (Prognostic) Inflammatory activity and fibrosis-stage on liver histopathology (METAVIR-and-Ishak scores) correlated with MMP-7 levels. APRI and FIB-4 scores also depicted a strong correlation with each other, age of the patient, and liver fibrosis. Conclusions MMP-7 has a diagnostic value in differentiating EHBA from NH and may also be used as a prognostic biomarker in the follow-up of these patients. MMP-7 levels in controls may be used as a baseline for future studies.

Abstract
BACKGROUND/AIMS Gut-barrier dysfunction is well recognized in pathogenesis of both non-alcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD). However, comparison of components of this dysfunction between the two etiologies remains unexplored especially in early stages of NAFLD. METHODS Components of gut-barrier dysfunction like alterations in intestinal permeability (IP) by lactulose mannitol ratio (LMR) in urine, systemic endotoxemia (IgG and IgM anti-endotoxin antibodies), systemic inflammation (serum tumor necrosis factor alpha [TNF-α] and interleukin-1 [IL-1] levels), tight junction (TJ) proteins expression in duodenal biopsy and stool microbiota composition using Oxford Nanopore MinION device were prospectively evaluated in patients with NAFLD (n = 34) with no cirrhosis, ALD (n = 28) and were compared with disease free controls (n = 20). RESULTS Patients with ALD had more advanced disease than those with NAFLD (median liver stiffness -NAFLD:7.1 kPa [5.9-8.9] vs. ALD:14.3 kPa [9.6-24], P < 0.001]. Median LMR was significantly higher in NAFLD and ALD group when compared to controls (NAFLD 0.054 [0.037-0.17] vs. controls 0.027 [0.021-0.045] (P = 0.001)) and ALD 0.043 [0.03-0.068] vs. controls 0.027 [0.021-0.045] (P = 0.019)]. Anti-endotoxin antibody titer (IgM) (MMU/mL) was lowest in NAFLD 72.9 [3.2-1089.5] compared to ALD 120.6 [20.1-728]) (P = 0.042) and controls 155.3 [23.8-442.9]) (P = 0.021). Median TNF-α (pg/mL) levels were elevated in patients with NAFLD (53.3 [24.5-115]) compared to controls (16.1 [10.8-33.3]) (P < 0.001) and ALD (12.3 [10.1-42.7]) (P < 0.001). Expression of zonulin-1 and claudin-3 in duodenal mucosa was lowest in NAFLD. On principal co-ordinate analysis (PCoA), the global bacterial composition was significantly different across the three groups (PERMANOVA test, P < 0.001). CONCLUSION While remaining activated in both etiologies, gut-barrier dysfunction abnormalities were more pronounced in NAFLD at early stages compared to ALD despite more advanced disease in the latter.

Abstract
India is the highest TB burden country in the world. The burden however is not uniform in different strata including tribal population - one of the key affected populations in the country. As the evidences from tribal population are hardly available, most of the policies and strategies implemented under National Tuberculosis Elimination Programme (NTEP) are usually based on the evidences from general populations. NTEP is continuously taking steps to strengthen TB services in tribal areas. The Social Action Plan including Tribal Action Plan is in place and the appropriate strategies are incorporated in the National Strategic Plan (NSP) to ensure universal access to quality TB services to vulnerable population groups. However, its implementation becomes challenging especially in tribal areas as different tribal groups have their own unique ways of dealing with health issues. These issues are therefore required to be addressed holistically involving all the stakeholders. In view of this a symposium was jointly organized by the Central TB Division (CTD), Govt. of India and ICMR - National Institute of Research in Tribal Health (NIRTH), Jabalpur on 17th and 18th December, 2019 at ICMR - NIRTH, Jabalpur. It provided an excellent platform for all the stakeholders from different parts of the country to share their experiences in tuberculosis particularly among marginalized populations. The recommendations emerged out of this interactive symposium highlight the sincere effort of NTEP to tackle TB situation in tribal population and show the way forward towards India's TB elimination goal by 2025 especially in hard to reach tribal areas.

Abstract
Congenital diarrhea and enteropathies (CODEs) are monogenic disorders causing early onset of intractable diarrhea. Their diagnosis and management are challenging. With the availability of commercial next generation genetic testing, we are now better able to classify and manage these disorders. The authors present their experience with 4 cases. Two patients had congenital tufting enteropathy (CTE) and 1 case each of microvillous inclusion disease (MVID) and trichohepatoenteric syndrome (THES). Age at onset varied from 3 to 38 d of life. Light microscopy and electron microscopy of duodenal and rectal endoscopic biopsies were consistent with the diagnosis. Genetic evaluation was possible in 3 cases indicating causative mutations. Two children (CTE and MVID) were alive at last follow-up. The authors suggest a stepwise approach to the diagnosis and management of these disorders in the Indian context.

Abstract
CONTEXT.— The histologic features in patients with acute-on-chronic liver failure (ACLF) are evolving and histologic indicators of patients' poor prognosis are not yet fully established. OBJECTIVE.— To evaluate the independent histologic predictors of 28-day mortality in ACLF patients on core-needle liver biopsies. DESIGN.— Core-needle biopsies from patients with a diagnosis of ACLF (n = 152) as per the European Association for the Study of the Liver criteria were included during 8 years. Liver biopsies from 98 patients with compensated chronic liver disease were included as disease controls for histologic comparison. Features of ongoing changes, such as hepatic necrosis, hepatic apoptosis, cholestasis, hepatocyte degeneration, bile ductular proliferation, Mallory Denk bodies, steatosis, and extent of liver fibrosis, were analyzed for predicting short-term mortality (28 days). A P value of <.05 was considered significant. RESULTS.— In our cohort of ACLF patients, the following etiologies for acute decompensation were identified: alcohol, 47 of 152 (30.9%); sepsis, 24 of 152 (15.7%); hepatotropic viruses, 20 of 152 (13.1%); drug-induced liver injury, 11 of 152 (7.2%); autoimmune flare, 9 of 152 (5.9%); mixed etiologies, 5 of 152 (3.2%); and cryptogenic, 36 of 152 (23.6%). On histologic examination, hepatic necrosis (P < .001), dense lobular inflammation (P = .03), cholestasis (P < .001), ductular reaction (P = .001), hepatocyte degeneration (P < .001), and absence of advanced fibrosis stages (P < .001) were identified significantly more in ACLF patients than in disease controls on univariate analysis. On multivariate Cox regression analysis, the absence of advanced Ishak histologic activity index fibrosis stages (P = .02) and the presence of dense lobular inflammation (P = .04) were associated with increased 28-day mortality in ACLF patients. After adjusting the clinical causes of acute decompensation, only dense lobular inflammation was found as an independent predictor of short-term mortality (P = .04) in ACLF patients. CONCLUSIONS.— Dense lobular necroinflammatory activity is a clinically independent histologic predictor of 28-day short-term mortality in patients with ACLF.

Abstract
The management of drug-resistant (DR) tuberculosis (TB) remains a challenge particularly in remote rural areas of the country. Although the treatment with wholly oral drug regimens, including bedaquiline (BDQ) and delamanid, is rolled out under the National TB Elimination Program, little is known about its coverage and the effectiveness in hard-to-reach tribal areas. The present report describes the early identification and successful management, through team effort, of a case of extensively DR TB belonging to the Saharia tribe - a Particularly Vulnerable Tribal Groups (PVTGs) of Madhya Pradesh, which has a very high prevalence of TB. The BDQ-containing regimen was well tolerated and found effective with minimal side effects and contributed to the reduced time to culture conversion and radiological improvements. The concerted efforts and strategies need to be adopted for effective implementation of Programmatic management of DR TB (PMDT) guidelines in remote tribal areas of the country.

Abstract
Giant cell tumor of the larynx is an uncommon entity with only 44 cases reported in the literature. These tumors occur most commonly in the epiphysis of the long bones of female patients in third decade. Here in we report a case of 23 years old male patient who presented with an anterior neck swelling since past 4 months. Ultrasound and computed tomography of neck revealed a heterogenously enhancing lesion involving posteroinferior half of right thyroid cartilage with extension into the extra laryngeal strap muscle and intralaryngeal right true vocal cord and false vocal cord. The findings were suggestive of a neoplastic cartilagenous lesion. A fine needle aspiration of the right anterior neck mass was performed which showed many mononuclear cells along with multinucleated osteoclast type giant cells. No thyroid follicular cells or inflammatory cells were seen. A diagnosis of giant cell tumor of the thyroid cartilage was rendered on cytology. A biopsy was subsequently performed for the patient which confirmed the same. Hence, although giant cell tumor of the larynx is a rare entity, with very few cases reported in the literature, these tumors should be included in the differential diagnosis of giant cell lesions of the neck and aspiration cytology can offer an accurate and quick diagnosis in such cases.

Abstract
OBJECTIVE We assessed the long-term survival of TB patients belonging to the Saharia tribe, a high TB burden community in Shivpuri district, Madhya Pradesh, central India. METHODS Population-based, longitudinal study conducted among 9756 Saharia population in 2013, and a resurvey done 2 years later in 2015 using the same methods. The status of the individuals during resurvey was recorded as non-TB, relapse and death. The deaths recorded in this period were used to measure the mortality among TB-affected population and the non-TB population in this cohort. RESULTS The standardised mortality ratio for the study cohort was 122.9 per 1000 population; males had higher mortality than females (129.9 vs. 96.8). The expected mortality among the non-TB population was 30.2, and the observed mortality among TB-affected population was 122.9 per 1000 population. CONCLUSION In the Saharia tribe, post-treatment mortality in the TB-affected population is significantly higher than in the general population. This highlights an urgent need for implementation of effective public health strategies to prevent disproportionate deaths among TB-affected individuals in resource-poor settings, and the importance of periodic follow-up of patients after cure/completion of treatment, especially in vulnerable populations.

Abstract
Fine-needle aspiration cytology (FNAC) is an effective tool for early and quick diagnosis of malignant and metastatic liver masses. However, diagnosing a benign liver tumor on cytology is a challenging task as they are rarely assessed on cytology and also due to the limitations of the procedure. Mesenchymal hamartoma is an uncommon benign pediatric liver tumor and difficult to diagnose on cytology. We describe here a case of a child who presented with a huge liver mass and clinical suspicion of hepatoblastoma. The child underwent blind FNA, and was diagnosed as mesenchymal hamartoma based on the cytological features. A biopsy was performed subsequently which confirmed the same and then he underwent surgical resection of the tumor. The patient had an uneventful recovery and is disease free on follow up.

Abstract
Hepatocellular carcinoma (HCC) is an aggressive gastrointestinal malignancy with a high rate of mortality. Multiple studies have individually recognized members of RAP gene family as critical regulators of tumor progression in several cancers, including hepatocellular carcinoma. These studies suffer numerous limitations including a small sample size and lack of analysis of various clinicopathological and molecular features. In the current study, we utilized authoritative multi-omics databases to determine the association of RAP gene family expression and detailed molecular and clinicopathological features in hepatocellular carcinoma (HCC). All five RAP genes were observed to harbor dysregulated expression in HCC compared to normal liver tissues. RAP2A exhibited strongest ability to differentiate tumors from the normal tissues. RAP2A expression was associated with progressive tumor grade, TP53 and CTNNB1 mutation status. Additionally, RAP2A expression was associated with the alteration of its copy numbers and DNA methylation. RAP2A also emerged as an independent marker for patient prognosis. Further, pathway analysis revealed that RAP2A expression is correlated with tumor-infiltrating immune cell composition and oncogenic molecular pathways, such as cell cycle and cellular metabolism.

Abstract
Cervicitis is predominantly caused by Neisseria gonorrhoeae and Chlamydia trachomatis, which accounts for almost half of all the cases of cervicitis. The role of newer organisms like Mycoplasma genitalium and Ureaplasma sp. and association of bacterial load with cervicitis are also not well established. So the study aimed to determine the relative frequency of these organisms and their load in association with cervicitis cases from north India. A case-control study involving 300 women was conducted using quantitative real-time PCR from endocervical swabs for identification of organisms and quantification of bacterial load. Among 150 cervicitis cases, C. trachomatis, N. gonorrhoeae, M. genitalium and Ureaplasma parvum were detected in 5 (3·3%), 10 (6·6%), 37(24·6%) and 47 (31·3%) respectively. Old age (<0·001, chi-squared test) and irregular menstrual cycles (<0·001, chi-squared test) were significantly associated with cervicitis. M genitalium was the only organism to be associated significantly with cervicitis with regard to age (<0·031) and symptoms like discharge (P < 0·033, chi-squared test) and dysuria (P < 0·044, chi-squared test) in multivariate analysis. Our finding suggests that the bacterial load of these organisms is not significantly associated with cervicitis. However, we found significant association of M. genitalium infection with clinical characteristics of cervicitis cases.

Abstract
BACKGROUND AND AIM The FibroScan-aspartate aminotransferase (FAST) score was developed for identifying patients with non-alcoholic steatohepatitis, who also have an elevated non-alcoholic fatty liver disease (NAFLD) activity score (NAS) ≥ 4 and significant fibrosis (F ≥ 2). We aimed to validate it in our NAFLD cohort and assess if it correlates with the histological changes after bariatric surgery. METHODS Patients with NAFLD, including those undergoing bariatric surgery, were included. The FAST score was calculated using liver stiffness measure, controlled attenuation parameter, and aspartate aminotransferase. Calibration and discrimination of the model were assessed by calibration plots and area under the receiver operating characteristic curve, respectively. Sensitivity and specificity were assessed at the rule-out and rule-in cutoffs (≤0.35 and ≥0.67), respectively. Changes in the NAS and FAST scores were compared in the bariatric cohort 1 year after surgery. RESULTS The cohort composed of 309 patients, of which 48 patients underwent repeat liver biopsy at 1 year. The model showed good discrimination with area under the receiver operating characteristic curve of 0.79 (0.74-0.84); however, it was not satisfactorily calibrated (Hosmer-Lemeshow test, P = 0.008). The sensitivity and specificity at the rule-out and rule-in cutoffs were 0.90 and 0.84, respectively. A significant correlation was seen between the 1-year reduction in the NAS and FAST scores (r = 0.38, P = 0.009). A significant reduction in the median FAST score was seen in patients who had ≥2-point reduction in NAS after bariatric surgery. CONCLUSION FibroScan-aspartate aminotransferase score demonstrated good discrimination for fibrotic non-alcoholic steatohepatitis in our cohort. However, a miscalibration resulted in overprediction. The score correlated well with the histological response to interventions for NAFLD.

Abstract
Background Lipomas are benign adipocytic tumours. Surgical excision is the gold standard for treating such lipomas, but it results in unaesthetic scarring. Methods A total of 126 patients were randomised into two groups. The patients in Group A underwent mesotherapy (n = 66) and those in Group B underwent surgery (n = 60). The patients in Group A group received six sessions of mesotherapy treatment at 2-week intervals. Both groups were followed up for 12 weeks, during which they were assessed for complications arising from treatment, reduction of the size of the lipoma and cosmetic outcomes. Results The overall mean age of the patients was 32.93 (± 10.1) years old and the mean volume of the lipomas was 2.29 (± 3.8) mL. A 55.86% (P = 0.0032) mean reduction in the volume of lipomas was noted in the patients who received mesotherapy, while one patient showed a gain of 16% by volume. The patients in Group A (cosmetic score ≥ 4: 63%) were happier with the treatment than those in Group B (cosmetic score ≥ 4: 21%). Conclusion Our findings indicate that mesotherapy modestly reduces the volume of lipomas with very few and minor complications and excellent cosmetic outcomes.
