Analysis of Different Routes of Hysterectomy Based on a Prospective Algorithm and Their Complications in a Tertiary Care Institute.

Introduction: Hysterectomy is the most common gynaecological operation worldwide. The objective of the study is to analyze the various routes of hysterectomy and its complications when the decision of route is based on using a prospective algorithm tree. Methodology. It is an observational study to analyze the route of hysterectomy based on using a prospective algorithm. The decision tree is based on pelvic pathology, uterine size, vaginal access, pelvic adhesion, competency of the surgeon, choice of the patient, and complication of different routes of hysterectomy. Data were collected from preoperative, intraoperative, and postoperative records. Demographic factors, indications, routes of hysterectomy, and complications were recorded and analyzed by using SPSS software version 22. Observation. Among the malignant or suspected malignant pathology groups, TAH was performed in 89 cases and TLH was performed in 3 cases. Among the benign disease groups, VH was performed in 137(38.2%) cases, TAH was performed in 118(32.9%) cases, and TLH was performed in 104 (28.9%) cases. Operative time and a number of blood transfusions were significantly less with VH (p value < 0.0001 and 0.004) compared to abdominal and total laparoscopic hysterectomy. Postoperative complication such as fever was more with abdominal hysterectomy (p-value<0.00001) compared to VH and TLH. Vaginal discharge was more with VH and TLH compared to TAH (p value -0.004) and wound infection was more in the abdominal route (p value 0.001). Conclusion: The abdominal route was the route of choice for surgery in malignancy or suspected malignant pathology. In benign pathology, VH was the most common and preferable route of surgery. Complications were found to be minimal with vaginal hysterectomy.

Amniotic Fluid Embolism After First-Trimester Abortion.

Amniotic fluid embolism (AFE) may be a rare event in pregnancy, especially after a first-trimester medical termination of pregnancy (MTP). A 35-year-old G3P2L2 came to our outpatient department at six weeks of pregnancy for medical termination of pregnancy and bilateral tubal ligation. After around one hour of surgery, she developed respiratory distress with abdominal distension, hypotension, tachycardia and tachypnoea. On laparotomy, we found ascitic fluid, bowels with petechia, and oozing all over the wounds. Finally, within 24 hours of surgery, she expired. Strong clinical suspicion of AFE should prompt a multidisciplinary team including anaesthesia, respiratory therapy, critical care, and maternal-foetal medicine to be involved in the ongoing care of women with AFE.

An Unusual Case of Retained Foreign Body in the Vagina With Vaginal Fibrosis.

Vaginal foreign bodies can cause long haul, foul-smelling vaginal discharge and vaginal bleeding and are typically found in female youngsters while looking into vaginitis and urinary tract diseases. There are many causes for vaginal discharges. Among them, vaginal foreign bodies are uncommon but not a very rare presentation. We had a case of a 49-year-old female, a widow, with para 2 living 2 and a history of menopause since three years; she was referred from a district hospital with a diagnosis of carcinoma of the cervix and was later found to have a foreign body, which was removed surgically through the vagina. A foreign body in the vagina is usually seen in children than in adults. Foreign bodies are inserted vaginally for treatment purposes, contraception, induced abortion, and sexual stimulation in adults. Here, we report a case of retained vaginal foreign body with vaginal fibrosis.

Identification of High-Risk Aberrant Crypt Foci and Mucin-Depleted Foci in the Human Colon With Study of Colon Cancer Stem Cell Markers.

BACKGROUND: During colonoscopic screening, only macroscopic lesions will be identified, and these are usually the result of multiple genetic abnormalities. Magnification endoscopic detection of aberrant crypt foci (ACF), long before they acquire complex genetic abnormalities, is promising. However, the features of high-risk ACF-like lesions need to be identified. MATERIALS AND METHODS: In the present cross-sectional study, grossly visible normal mucosal flaps were shaved from 152 colectomies, including 96 colorectal cancer (CRC) cases and 56 controls (22 control specimens with disease with malignant potential and 34 without malignant potential). Methylene and Alcian blue stains were performed directly on the unfixed mucosal flaps to identify ACF and mucin-depleted foci (MDF). Detailed topographic analyses, with immunohistochemical staining for ß-catenin and cancer stem cell (CSC) markers (CD44, CD24, and CD166) were performed. RESULTS: ACF, MDF, and ß-catenin-accumulated crypts were detected more in specimens with adjacent CRC. The left colon had ACF with a larger diameter and greater crypt multiplicity, density, and gyriform pit pattern and were considered the high-risk ACF group. MDF, more commonly associated with dysplasia, is also a marker of possible carcinogenesis. The CD44 CSC marker was significantly upregulated in ACF specimens compared with normal controls. Our 3-tier ACF-only pit pattern classification system showed better linearity with mucosal dysplasia than did the 6-tier Kudo classification. CONCLUSION: High-risk ACF, when detected during chromoendoscopic screening, should be followed up. CSCs might play an important role in pathogenesis. Larger studies and genotypic risk stratification for definite identification of high-risk ACF are needed.

Patients with mild enteropathy have apoptotic injury of enterocytes similar to that in advanced enteropathy in celiac disease.

BACKGROUND: Severity of villous atrophy in celiac disease (CeD) is the cumulative effect of enterocyte loss and cell regeneration. Gluten-free diet has been shown to benefit even in patients having a positive anti-tissue transglutaminase (tTG) antibody titre and mild enteropathy. AIM: We explored the balance between mucosal apoptotic enterocyte loss and cell regeneration in mild and advanced enteropathies. METHODS: Duodenal biopsies from patients with mild enteropathy (Marsh grade 0 and 1) (n=26), advanced enteropathy (Marsh grade ≥2) (n=41) and control biopsies (n=12) were subjected to immunohistochemical staining for end-apoptotic markers (M30, H2AX); markers of cell death (perforin, annexin V); and cell proliferation (Ki67). Composite H-scores based on the intensity and distribution of markers were compared. RESULTS: End-apoptotic markers and marker of cell death (perforin) were significantly up-regulated in both mild and advanced enteropathies, in comparison to controls; without any difference between mild and advanced enteropathies. Ki67 labelling index was significantly higher in crypts of mild enteropathy, in comparison to controls, suggesting maintained regenerative activity in the former. CONCLUSIONS: Even in patients with mild enteropathy, the rate of apoptosis is similar to those with advanced enteropathy. These findings suggest the necessity of reviewing the existing practice of not treating patients with mild enteropathy.

Demographic profile, host, disease & viral predictive factors of response in patients with chronic hepatitis C virus infection at a tertiary care hospital in north India.

BACKGROUND & OBJECTIVES: Standard of care for chronic hepatitis C (CHC) in India is peginterferon and ribavirin (RBV). The response to treatment in real life stetting is unclear. The objectives of this study were to evaluate the demographic profile and assess the virological response and predictors of response in CHC patients. METHODS: Consecutive patients with CHC were included in this study. Detailed clinical history, risk factors, and predictive factors of response were noted. Patients were treated with peginterferon α2b (1.5 µg/kg/wk) and RBV (12 mg/kg/day) for 6 to 18 months based on response. RESULTS: A total of 211 patients were included in the analysis, mean age 40.6±12.3 yr, 144 (68%) were males and 71 (34%) had compensated cirrhosis. Commonest risk factor for acquiring CHC was previous transfusion and surgery (51%). Genotype 3 (72%) was most common followed by genotype 1 (23%). Overall sustained virologic response (SVR) was 64 per cent [95% CI 57.1%-70.4%]. The SVR was 66.5 per cent [95% CI 58.34-73.89%] for genotype 3 and 61.2 per cent [95% CI 46.23 to 74.80%] for genotype 1. Non-cirrhotics had better SVR rates compared to cirrhotics (76 vs 41%, p<0.001). On multivariate analysis, BMI ≥23 kg/m2, HOMA-IR ≥2, compliance (≤80%), and fibrosis >2 were predictors of low SVR. INTERPRETATION & CONCLUSIONS: Genotype 3 was the commonest HCV genotype. The commonest source of infection was previous transfusion and surgery. SVR rates for genotypes 3 were better than genotype 1 patients. Predictors of non-response were high BMI, insulin resistance, significant fibrosis and inadequate compliance.

TLR-mediated albuminuria needs TNFα-mediated cooperativity between TLRs present in hematopoietic tissues and CD80 present on non-hematopoietic tissues in mice.

Transient albuminuria induced by pathogen-associated molecular patterns (PAMPs) in mice through engagement of Toll-like receptors (TLRs) is widely studied as a partial model for some forms of human nephrotic syndrome (NS). In addition to TLRs, CD80 has been shown to be essential for PAMP-mediated albuminuria. However, the mechanistic relationships between TLRs, CD80 and albuminuria remain unclear. Here, we show that albuminuria and CD80-uria induced in mice by many TLR ligands are dependent on the expression of TLRs and their downstream signalling intermediate MyD88 exclusively in hematopoietic cells and, conversely, on CD80 expression exclusively in non-hematopoietic cells. TNFα is crucial for TLR-mediated albuminuria and CD80-uria, and induces CD80 expression in cultured renal podocytes. IL-10 from hematopoietic cells ameliorates TNFα production, albuminuria and CD80-uria but does not prevent TNFα-mediated induction of podocyte CD80 expression. Chitohexaose, a small molecule originally of parasite origin, mediates TLR4-dependent anti-inflammatory responses, and blocks TLR-mediated albuminuria and CD80-uria through IL-10. Thus, TNFα is a prominent mediator of renal CD80 induction and resultant albuminuria in this model, and small molecules modulating TLR-mediated inflammatory activation might have contributory or adjunct therapeutic potential in some contexts of NS development.

Steroid cell tumor: A rare virilizing ovarian tumor.

Steroid cell tumors of the ovary account for less than 0.1% of all ovarian tumors. These tumors may present at any age with presentations related to the hormonal activity and virilizing properties of tumor. We present a case report of a young girl with ovarian steroid cell tumor, who had a complete and dramatic response to surgery alone.

The G1 phase E3 ubiquitin ligase TRUSS that gets deregulated in human cancers is a novel substrate of the S-phase E3 ubiquitin ligase Skp2.

E3 ubiquitin ligases have been implicated in the ubiquitination and proteasome-mediated degradation of several key regulators of cell cycle. Owing to their pleotropic behavior, E3 ubiquitin ligases are tightly regulated both at transcriptional and post-translational levels. The E3 ubiquitin ligase TRUSS (tumor necrosis factor receptor-associated ubiquitous scaffolding and signaling protein) which negatively regulates c-Myc, are found down-regulated in most human cancer cell lines. However, the mechanism of regulation of intracellular levels of TRUSS remains elusive. Here we show that TRUSS is expressed majorly during the G1 phase of cell cycle and its level starts to decline with the expression of S-phase specific E3 ligase Skp2. Enforced expression of Skp2 led to a marked increase in the ubiquitination of TRUSS after its phosphorylation by GSK3ß and followed by rapid proteolytic degradation. Our co-immunoprecipitation studies suggested a direct interaction between Skp2 and TRUSS through the LRR motif of Skp2. Interestingly, the human tumor samples that exhibited elevated expression of Skp2, showed relatively poor expression of TRUSS. Further, enforced expression of HBx, the oncoprotein of Hepatitis B virus which is known to stabilize c-Myc and enhance its oncogenic potential, led to the intracellular accumulation of TRUSS as well as c-Myc. Apparently, HBx also interacted with TRUSS which negatively impacted the TRUSS-c-Myc and TRUSS-Skp2 interactions leading to stabilization of TRUSS. Thus, the present study suggests that TRUSS is a novel substrate of E3 ligase Skp2 and that disruption of TRUSS-Skp2 interaction by viral oncoproteins could lead to pathophysiological sequelae.

Hepatitis E virus (HEV) protease: a chymotrypsin-like enzyme that processes both non-structural (pORF1) and capsid (pORF2) protein.

Hepatitis E virus (HEV), a major cause of acute viral hepatitis across the world, is a non-enveloped, plus-strand RNA virus. Its genome codes three proteins, pORF1 (multifunctional polyprotein), pORF2 (capsid protein) and pORF3 (multi-regulatory protein). pORF1 encodes methyltransferase, putative papain-like cysteine protease, helicase and replicase enzymes. Of these, the protease domain has not been characterized. On the basis of sequence analysis, we cloned and expressed a protein covering aa 440-610 of pORF1, expression of which led to cell death in Escherichia coli BL-21 and Huh7 hepatoma cells. Finally, we expressed and purified this protein from E. coli C43 cells (resistant to toxic proteins). The refolded form of this protein showed protease activity in gelatin zymography. Digestion assays showed cleavage of both pORF1 and pORF2 as observed previously. MS revealed digestion of capsid protein at both the N and C termini. N-terminal sequencing of the ~35 kDa methyltransferase, ~35 kDa replicase and ~56 kDa pORF2 proteins released by protease digestion revealed that the cleavage sites were alanine15/isoleucine16, alanine1364/valine1365 in pORF1 and leucine197/valine198 in pORF2. Specificity of these cleavage sites was validated by site-directed mutagenesis. Further characterization of the HEV protease, carried out using twelve inhibitors, showed chymostatin and PMSF to be the most efficient inhibitors, indicating this protein as a chymotrypsin-like protease. The specificity was further confirmed by cleavage of the chymotrypsin-specific fluorogenic peptide N-succinyl-Leu-Leu-Val-Tyr-7-amido-4-methylcoumarin. Mutational analysis of the conserved serine/cysteine/histidine residues suggested that H443 and C472/C481/C483 are possibly the active site residues. To our knowledge, this is the first direct demonstration of HEV protease and its function.

RNA-seq based transcriptome analysis of hepatitis E virus (HEV) and hepatitis B virus (HBV) replicon transfected Huh-7 cells.

Pathogenesis of hepatitis B virus (HBV) and hepatitis E virus (HEV) infection is as varied as they appear similar; while HBV causes an acute and/or chronic liver disease and hepatocellular carcinoma, HEV mostly causes an acute self-limiting disease. In both infections, host responses are crucial in disease establishment and/or virus clearance. In the wake of worsening prognosis described during HEV super-infection over chronic HBV hepatitis, we investigated the host responses by studying alterations in gene expression in liver cells (Huh-7 cell line) by transfection with HEV replicon only (HEV-only), HBV replicon only (HBV-only) and both HBV and HEV replicons (HBV+HEV). Virus replication was validated by strand-specific real-time RT-PCR for HEV and HBsAg ELISA of the culture supernatants for HBV. Indirect immunofluorescence for the respective viral proteins confirmed infection. Transcription profiling was carried out by RNA Sequencing (RNA-Seq) analysis of the poly-A enriched RNA from the transfected cells. Averages of 600 million bases within 5.6 million reads were sequenced in each sample and ∼15,800 genes were mapped with at least one or more reads. A total of 461 genes in HBV+HEV, 408 in HBV-only and 306 in HEV-only groups were differentially expressed as compared to mock transfection control by two folds (p<0.05) or more. Majority of the significant genes with altered expression clustered into immune-associated, signal transduction, and metabolic process categories. Differential gene expression of functionally important genes in these categories was also validated by real-time RT-PCR based relative gene-expression analysis. To our knowledge, this is the first report of in vitro replicon transfected RNA-Seq based transcriptome analysis to understand the host responses against HEV and HBV.

Mechanism of villous atrophy in celiac disease: role of apoptosis and epithelial regeneration.

CONTEXT: The data on status of apoptosis in patients with celiac disease are conflicting. Furthermore, complex interaction between intrinsic and common apoptotic pathways, apoptotic inhibitors, and epithelial cell proliferation is largely unclear for patients with celiac disease. OBJECTIVES: To determine the role of apoptosis and epithelial cell regeneration in celiac disease. DESIGN: Twenty-five treatment-naïve patients with celiac disease and 6 patients with functional dyspepsia, as controls, were included and duodenal biopsy specimens from all were subjected to immunohistochemistry with markers of intrinsic apoptotic pathway (AIF, H2AX, p53), common pathway (CC3, M30), apoptotic inhibitors (XIAP, Bcl2), and epithelial proliferation (Ki-67). Apoptotic and proliferation indices were calculated. RESULTS: Expression of end-apoptotic products, that is, H2AX in the cell nuclei (P = .01) and M30 in the cell cytoplasm (P < .01), was significantly upregulated in celiac disease in comparison to controls. Cleaved caspase-3 was also upregulated in villous cytoplasm in celiac disease. Apoptotic inhibitor Bcl2 was significantly down-regulated in celiac disease in comparison to controls. In addition, Ki-67 proliferation index was upregulated both in the crypts and villous mucosal epithelium in comparison to the crypts of the controls. CONCLUSIONS: Treatment-naïve patients with celiac disease have significantly higher level of apoptosis that involves both the common and intrinsic apoptotic pathways. Increased apoptosis and unequaled cell regeneration in crypts probably results in villous atrophy. Down-regulation of apoptotic inhibitors in treatment-naïve celiac disease imparts an additional pro-apoptotic effect.

Fibroscan can avoid liver biopsy in Indian patients with chronic hepatitis B.

BACKGROUND AND AIM: Liver fibrosis is an established determinant of prognosis and therapy in chronic hepatitis B (CHB). The role of fibroscan in assessing fibrosis in CHB remains unclear. Present study was designed to correlate fibroscan with liver biopsy and determine whether fibroscan can avoid liver biopsy in patients with CHB. METHODS: Fibroscan and liver biopsy were performed in 382 consecutive patients with CHB. Biopsies were reviewed by pathologist blinded to the fibroscan value. Discriminant values of liver stiffness measurement (LSM) to reasonably exclude and predict significant fibrosis were calculated from receiver operating characteristic (ROC) curves. The factors affecting LSM independent of fibrosis were assessed. RESULTS: Three hundred fifty-seven patients were included (mean age 30.1 ± 9.7 years, male : female 17 : 3). There was significant correlation between LSM and histological fibrosis (r = 0.58, P < 0.001). The area under ROC curve of LSM for significant fibrosis (F0-1 vs. F2-4), bridging fibrosis (F0-2 vs. F3-4), and cirrhosis (F0-3 vs. F4) was 0.84 (95% CI: 0.78-0.89), 0.94 (95% CI: 0.89-0.99), and 0.93 (95% CI: 0.85-1.00), respectively. LSM < 6.0 KPa could exclude significant (F ≥ 2) and bridging fibrosis (F ≥ 3) with a negative predictive value (NPV) of 92.4% and 99.5%, respectively. Cut-off of 9 KPa could detect significant (F ≥ 2) and bridging fibrosis (F ≥ 3) with specificity of 95% and 97%, respectively, and had a positive predictive value (PPV) of 84.3% in predicting significant fibrosis. LSM < 6 KPa and > 9 KPa matched with histological fibrosis in 227/250 (91%) patients. Therefore, fibroscan could avoid liver biopsy in 70% (250/357) patients with an accuracy > 90%. Histological fibrosis, ALT > 5 times, and age > 40 years were independent determinants of increased liver stiffness. CONCLUSIONS: Fibroscan accurately assessed fibrosis and could avoid liver biopsy in more than two-thirds of patients with CHB.

Hepatitis e: molecular virology and pathogenesis.

Hepatitis E virus is a single, positive-sense, capped and poly A tailed RNA virus classified under the family Hepeviridae. Enteric transmission, acute self-limiting hepatitis, frequent epidemic and sporadic occurrence, high mortality in affected pregnants are hallmarks of hepatitis E infection. Lack of an efficient culture system and resulting reductionist approaches for the study of replication and pathogenesis of HEV made it to be a less understood agent. Early studies on animal models, sub-genomic expression of open reading frames (ORF) and infectious cDNA clones have helped in elucidating the genome organization, important stages in HEV replication and pathogenesis. The genome contains three ORF's and three untranslated regions (UTR). The 5' distal ORF, ORF1 is translated by host ribosomes in a cap dependent manner to form the non-structural polyprotein including the viral replicase. HEV replicates via a negative-sense RNA intermediate which helps in the formation of the positive-sense genomic RNA and a single bi-cistronic sub-genomic RNA. The 3' distal ORF's including the major structural protein pORF2 and the multifunctional host interacting protein pORF3 are translated from the sub-genomic RNA. Pathogenesis in HEV infections is not well articulated, and remains a concern due to the many aspects like host dependent and genotype specific variations. Animal HEV, zoonosis, chronicity in immunosuppressed patients, and rapid decompensation in affected chronic liver diseased patients warrants detailed investigation of the underlying pathogenesis. Recent advances about structure, entry, egress and functional characterization of ORF1 domains has furthered our understanding about HEV. This article is an effort to review our present understanding about molecular biology and pathogenesis of HEV.

Association of pro-inflammatory cytokines, adipokines & oxidative stress with insulin resistance & non-alcoholic fatty liver disease.

BACKGROUND & OBJECTIVES: The cytokines, adipokines, and oxidative stress have been implicated in the pathogenesis of non-alcoholic fatty liver disease (NAFLD); however, such data remain scarce in India. The present study evaluated pro-inflammatory cytokines, adipokines, and markers of oxidative stress in patients with non-alcoholic fatty liver disease (NAFLD), and their association with degree of adiposity, insulin resistance and markers of disease severity. METHODS: The present prospective cross-sectional pilot study included 79 subjects; 34 NAFLD, 22 chronic hepatitis B (CH-B) and 23 healthy controls (HC). The parameters studied were adiponectin, leptin, tumour necrosis factor α (TNFα), interleukin-1 and 6 (IL-1, IL-6), and systemic markers of oxidative stress. RESULTS: The mean body mass index (kg/m 2 ) in NAFLD patients, CHB, and HC were 26.4±3.7, 21.3±2.3, and 22.3±2.7, respectively. The median serum levels of all pro-inflammatory cytokines were significantly higher (P<0.001) in NAFLD compared to control groups. Compared to HC, levels of adiponectin and leptin were significantly (P<0.05, P<0.01) reduced in both NAFLD and CHB. IL-6 showed marked and selective increase only in NAFLD patients. The levels of IL-6 were significantly (P<0.02) higher in NAFLD patients with advanced histology grade and correlated with IR (r=0.42, P=0.02). In a sub-group, markers of oxidative stress were significantly higher, and that of antioxidant potential were significantly lower among NAFLD patients compared to control subjects. INTERPRETATION & CONCLUSIONS: Patients with NAFLD revealed significantly elevated levels of pro-inflammatory cytokines, increased oxidative stress, and a significant association of IL-6 with IR and advanced histopathology.

Effect of addition of short course of prednisolone to gluten-free diet on mucosal epithelial cell regeneration and apoptosis in celiac disease: a pilot randomized controlled trial.

BACKGROUND: Identification of adjuvant treatment is necessary for rapid and effective treatment in patients with celiac disease. In a pilot randomized controlled trial, the effect of prednisolone on enterocyte apoptosis and regeneration in celiac disease was investigated. PATIENTS AND METHODS: Thirty-three treatment-naïve patients with celiac disease were randomized to either gluten-free diet (GFD, n = 17) or GFD + prednisolone (1 mg/kg for 4 weeks, n = 16). Duodenal biopsies were taken at baseline and at 4 and 8 weeks posttreatment. Six patients with functional dyspepsia were recruited as controls. All these biopsies were stained for markers of intrinsic apoptotic pathway (AIF, H2AX, p53), common apoptotic pathway (CC3, M30), apoptotic inhibitors (XIAP, Bcl2), and epithelial proliferation (Ki-67). Apoptotic (AI) and proliferation indices (PI) were compared. RESULTS: At baseline duodenal biopsies, the end apoptotic products H2AX and M30 were significantly increased. In comparison with those treated with GFD alone, after 4 weeks of GFD + prednisolone treatment, some markers of both intrinsic and common apoptotic pathways showed rapid decline. After prednisolone withdrawal, there was overexpression of H2AX, CC3, and p53 in the latter group. In comparison with those treated with only GFD, patients treated with prednisolone showed suppression of mucosal PI, which started rising again after withdrawal of prednisolone. CONCLUSIONS: Apoptosis takes place in mucosal epithelium in celiac disease. Addition of short course of prednisolone suppresses apoptosis rapidly. However, it also suppresses epithelial regeneration; hence, if used, it should be withdrawn after an initial short course.

Comparative tight junction protein expressions in colonic Crohn's disease, ulcerative colitis, and tuberculosis: a new perspective.

We intended to see the pattern of TJ protein expression along with ultrastructural changes in colonic biopsies from patients with Crohn's disease (CD), ulcerative colitis (UC), and tuberculosis (cTB). Colonic biopsies from 11 patients with active CD and ten patients each with active UC and untreated cTB were taken along with biopsies from six patients with irritable bowel syndrome as controls. These were evaluated for expression pattern of key TJ proteins which included claudin-2 as TJ pore-forming protein, claudin-4 as pore-sealing protein, ZO-1 as scaffold protein, and occludin as TJ protein related to cell migration and polarity. Claudin-2 expression was upregulated along the whole length of intercellular junction (ICJ) in biopsies from patients with active CD and UC in comparison to the biopsies from cTB patients and controls, where its expression was limited to the uppermost part of ICJ. There was reduced expression of ZO-1 in UC, CD, and cTB. On transmission electron microscopic examination, the pentalaminar structure of TJs was destroyed in patients with CD and UC but no significant change was seen in those with cTB and in controls. The expression of claudin-2 was distinctly different in active CD and UC in comparison to its expression pattern in patients with cTB and in controls. The redistribution of claudin-2 expression was in accordance with the TJ ultrastructural changes in patients with UC, CD, and cTB. Altered claudin-2 expression, along with destroyed TJs, may result in loss of selective permeability in patients with UC and CD.

Acute abdomen with hemoperitoneum in a postmenopausal woman.

Gynecological emergencies may be encountered in postmenopausal ladies like that of ruptured ectopic pregnancy in the reproductive age group. We report a case of ruptured granulosa cell tumor in a 70-year-old woman who presented with acute abdomen and hemoperitoneum.
