RESUMO

BACKGROUND: Yellow or stripe rust, caused by the fungus Puccinia striiformis f. sp. tritici (Pst) is an important disease of wheat that threatens wheat production. Since developing resistant cultivars offers a viable solution for disease management, it is essential to understand the genetic basis of stripe rust resistance. In recent years, meta-QTL analysis of identified QTLs has gained popularity as a way to dissect the genetic architecture underpinning quantitative traits, including disease resistance. RESULTS: Systematic meta-QTL analysis involving 505 QTLs from 101 linkage-based interval mapping studies was conducted for stripe rust resistance in wheat. For this purpose, publicly available high-quality genetic maps were used to create a consensus linkage map involving 138,574 markers. This map was used to project the QTLs and conduct meta-QTL analysis. A total of 67 important meta-QTLs (MQTLs) were identified which were refined to 29 high-confidence MQTLs. The confidence interval (CI) of MQTLs ranged from 0 to 11.68 cM with a mean of 1.97 cM. The mean physical CI of MQTLs was 24.01 Mb, ranging from 0.0749 to 216.23 Mb per MQTL. As many as 44 MQTLs colocalized with marker-trait associations or SNP peaks associated with stripe rust resistance in wheat. Some MQTLs also included the following major genes- Yr5, Yr7, Yr16, Yr26, Yr30, Yr43, Yr44, Yr64, YrCH52, and YrH52. Candidate gene mining in high-confidence MQTLs identified 1,562 gene models. Examining these gene models for differential expressions yielded 123 differentially expressed genes, including the 59 most promising CGs. We also studied how these genes were expressed in wheat tissues at different phases of development. CONCLUSION: The most promising MQTLs identified in this study may facilitate marker-assisted breeding for stripe rust resistance in wheat. Information on markers flanking the MQTLs can be utilized in genomic selection models to increase the prediction accuracy for stripe rust resistance. The candidate genes identified can also be utilized for enhancing the wheat resistance against stripe rust after in vivo confirmation/validation using one or more of the following methods: gene cloning, reverse genetic methods, and omics approaches.

RESUMO

In wheat, lodging is affected by anatomical and chemical characteristics of the stem cell wall. Plant characteristics determining the stem strength were measured in lodging tolerant mutant (PMW-2016-1) developed through mutation breeding utilizing hexaploid wheat cultivar, DPW-621-50. Various anatomical features, chemical composition, and mechanical strength of the culms of newly developed lodging-tolerant mutant (PMW-2016-1) and parent (DPW-621-50), were examined by light microscopy, the Klason method, prostate tester coupled with a Universal Tensile Machine, and Fourier Transform Infrared Spectroscopy. Significant changes in the anatomical features, including the outer radius of the stem, stem wall thickness, and the proportions of various tissues, and vascular bundles were noticed. Chemical analysis revealed that the lignin level in the PMW-2016-1 mutant was higher and exhibited superiority in stem strength compared to the DPW-621-50 parent line. The force (N) required to break the internodes of mutant PMW-2016-1 was higher than that of DPW-621-50. The results suggested that the outer stem radius, stem wall thickness, the proportion of sclerenchyma tissues, the number of large vascular bundles, and lignin content are important factors that affect the mechanical strength of wheat stems, which can be the key parameters for the selection of varieties having higher lodging tolerance. Preliminary studies on the newly identified mutant PMW-2016-1 suggested that this mutant may possess higher lodging tolerance because it has a higher stem strength than DPW-621-50 and can be used as a donor parent for the development of lodging-tolerant wheat varieties.

RESUMO

OBJECTIVE: Comparison of virtual CT enteroscopy (VCTE) using carbon dioxide with small-bowel enteroclysis (SBE) and capsule endoscopy (CE) in small-bowel tuberculosis (SBTB). METHODS: This prospective study comprised consecutive patients suspected to have SBTB. VCTE and SBE were performed on the same day and evaluated by independent radiologists. CE was performed within 2 weeks. VCTE was performed following insufflation of carbon dioxide via catheters in the jejunum and anorectum. A contrast-enhanced CT was followed by a delayed non-contrast CT. Image processing was done using virtual colonoscopy software. Findings on VCTE, SBE, and CE were compared. The final diagnosis of SBTB was based on either histopathological or cytological findings, response to antitubercular treatment, or a combination of these. RESULTS: Of the 55 patients in whom VCTE was performed, complete data was available in 52 patients. A final diagnosis of SBTB was established in 37 patients. All patients had VCTE and SBE. CE was performed in 34 patients. Adequate luminal distension was achieved in all patients with SBE and 35 patients with VCTE. SBE showed more strictures in jejunum (10.8%) and ileum (75.7%) compared with VCTE (jejunum, 8.1%, and ileum, 64.9%) and CE (jejunum, 5.9%, and ileum, 61.8%). However, difference was not statistically significant. VCTE revealed a greater length of strictures in both the jejunum and ileum compared with SBE and CE. CONCLUSION: VCTE allows adequate evaluation of the bowel in most patients with SBTB. It allows detection of greater length of abnormality in jejunum and ileum compared with SBE and CE. KEY POINTS: • The use of VCTE using CO2 bowel insufflation in patients with SBTB should be considered. • VCTE allows detection of a greater length of abnormality in the jejunum and ileum.

RESUMO

OBJECTIVES: To study the natural course of patients with acute pancreatitis (AP) with acute kidney injury (AKI) and their cytokine profile. METHODS: Natural course of patients with AP and AKI was studied in 97 individuals. Levels of TNFα, IL-6, IL-10, IL-8 and IL-1ß were measured at presentation and at 72 h in patients who developed AKI. RESULTS: Amongst the entire cohort, 16.4% patients developed AKI (persistent AKI - 11 patients, transient AKI - 5 patients). Mortality rate was 25% amongst patients with AKI. Levels of IL-6 (p = 0.035) and IL-8 (p = 0.002) were found to be significantly higher in the AKI group. On multivariate analysis, IL-8 levels at baseline were found to be an independent predictor of AKI. AKI group had significant rise of TNF-α (P < 0.001), IL-6 (P < 0.001) and IL- 1ß (P < 0.001) on day 3 whereas persistent-AKI group had significant rise of TNF-α (p = 0.031), IL-6 (p = 0.001) and IL-1ß on day 3 and significant decline of IL-10 (p = 0.015). Using a cut-off of 105 pg/ml, IL-8 levels at baseline could predict AKI with a sensitivity of 87.5% and specificity of 59.2%, with area under the curve being 0.744 (p = 0.002). CONCLUSION: AP patients developing AKI have poor prognosis. IL-8 levels can predict AKI in patients with AP.

RESUMO

BACKGROUND AND AIMS: This retrospective study was aimed at assessing the efficacy of endoscopic dilation for esophageal anastomotic strictures, and to compare response between caustic anastomotic strictures (CAS) and non-caustic anastomotic strictures (NCAS). MATERIALS AND METHODS: Patients with anastomotic strictures (enrolled during January 1996-December 2015) were analyzed. Short- and long-term outcomes of dilation, in terms of clinical success, refractory, and recurrent strictures were compared between NCAS and CAS. Patients with refractory and recurrent strictures were managed with adjunctive therapy including intralesional steroids. Factors predicting refractoriness at start of dilation and reasons for more than ten lifetime dilations were also evaluated. RESULTS: Of the 142 patients, 124 (mean age-44.02; males-74) underwent dilation. Clinical success was achieved in 113 (91.3%) patients requiring a median [Interquartile range (IQR)] of 4 (2-10) sessions. The number of dilations to achieve clinical success, refractory strictures, and recurrent strictures, and the use of adjunctive therapy were significantly higher for CAS than for NCAS. Intralesional steroid use decreased periodic dilation index (PDI) significantly in CAS. Caustic etiology and starting dilation diameter of < 10 mm were found to be predictors of refractoriness, with the former alone being an independent predictor of more than ten lifetime dilations. No patient had free perforation; however, five required revision surgery. CONCLUSION: Patients with CAS fared worse than those with NCAS in terms of number of dilations, refractoriness, recurrence of strictures, and need of adjunctive therapy. Endoscopic dilation can successfully ameliorate dysphagia due to anastomotic strictures in a majority of patients.

RESUMO

BACKGROUND: Opioids and non steroidal anti inflammatory drugs (NSAIDs) are commonly used for pain relief in acute pancreatitis (AP). Opioids carry risk of sphincter of oddi constriction. Although diclofenac prevents post endoscopic retrograde cholangio-pancreatography (ERCP) pancreatitis, few reports of diclofenac associated AP are also present. Although, both tramadol and diclofenac are commonly used for pain relief in AP, no study has evaluated their comparative efficacy and safety. MATERIALS AND METHODS: Forty-six eligible participants were randomized to either diclofenac or tramadol. Primary objectives of our study were improvement in pain intensity on visual analogue scale (VAS pain score after 1 hr of drug administration) and number of patients requiring supplementary analgesia. The secondary objectives were total number of times of supplementary analgesia requirement, time to significant decrease (33%) in VAS pain score from baseline, number of painful days (VAS pain score >5), VAS pain score on 7th day, side effects, all cause death and complications of pancreatitis between the two groups. RESULTS: Although 46 patients were randomized, the final analysis included 41 participants. Five patients were withdrawn from the study (intubation = 3, altered sensorium = 2). No significant difference was seen in terms of VAS score after 1 hr of drug administration, number of patients requiring supplementary analgesic and number of painful days. However, time taken to significant reduction of pain was lower in the diclofenac group (p = .028). Both the agents were comparable in terms of safety. Although complications were less in the diclofenac group, the difference was not statistically significant. CONCLUSION: Both diclofenac and tramadol are equally effective in controlling pain in AP with similar safety profile. SIGNIFICANCE: There are no studies that have compared the safety and efficacy of two commonly used analgesics for pain relief in patients with AP. We found that both diclofenac and tramadol are equally effective in decreasing the pain associated with AP. There is also no significant difference in the incidence of side effects between both the groups. Hence both diclofenac and tramadol can be used safely and effectively for pain control in AP. TRIAL REGISTRATION: The trial was registered with clinical trials registry India (Number- CTRI/2018/05/014309).

RESUMO

BACKGROUND: Quality of life (QOL) in children with celiac disease (CD) has been sparsely studied. AIMS: We aimed to study QOL in pediatric CD and the effect of a gluten-free diet (GFD) in a North Indian population. METHODS: QOL was assessed at baseline and 6 months after GFD using a pediatric symptom checklist (PSC) score. The effect of GFD was assessed using a CD-specific questionnaire on domains such as dietary compliance, parental behavior and perceptions, children's feeling, and difficulty identifying gluten-free foods. RESULTS: A total of 60 CD children (age 6.03 ± 0. 42 years, range: 2-12 years, M:F 2:1) were prospectively enrolled. The median PSC score at baseline was 11.5 (2-35), which showed a statistically significant improvement after GFD to 2.5 (0-34) (P < 0.001). Significant concerns regarding specific domains emerged: difficulty in maintaining GFD 26.2%, at school 14.3%, at parties 43.2%, poor taste 11.4%, special diet a burden 28.5%, felt left out at school or friend's home 40.9%, felt different from other kids 40.9%, felt embarrassed to bring GFD to parties 54.6%, felt angry about following a special diet 56.8%, felt not invited out for meals because of CD 13.6%, and difficulty determining if food available was gluten free in 75%. CONCLUSION: GFD has a significant impact on emotional, behavioral, and psychosocial domains in children with CD. Proper labeling of commercially available food items, counseling, and patient support groups are the need of the hour.

RESUMO

BACKGROUND: Percutaneous catheter drainage (PCD) is used as the first step in the management of symptomatic fluid collections in patients with acute pancreatitis (AP). There are limited data on the effect of PCD on inflammatory markers. AIM: To study the effects of PCD on serum levels of C-reactive protein (CRP), IL-6, and IL-10 and its correlation with the outcome. METHODS: Consecutive patients of AP with symptomatic fluid collections undergoing PCD were evaluated for serum levels of CRP, IL-6, and IL-10 before PCD and at 3 and 7 days after PCD. Resolution of organ failure (OF), sepsis, and pressure symptoms was considered to demonstrate the success of PCD. Changes in levels following PCD were correlated with outcome. RESULTS: Indications of PCD in 59 patients (age 38.9 ± 13.17 years, 49 male) were suspected/documented infected pancreatic necrosis (n = 45), persistent OF (n = 40), and pressure symptoms (n = 7). A total of 49 (83.1%) patients improved with PCD, five patients required surgery, and six died. A significant difference was noted between baseline levels of CRP (P = 0.026) and IL-6 (P = 0.013) among patients who improved compared to those who worsened following PCD. Significant decrease (P < 0.01) of all three markers on day 3 of PCD insertion, with further decrease (P < 0.01) on day 7, was noted. The percentage of the decrease of IL-6 levels on day 3 and of CRP on day 7 correlated with the outcome. CONCLUSION: PCD is associated with a significant decrease in CRP, IL-6, and IL-10 levels. Percentage decrease in IL-6 on day 3 and CRP on day 7 correlated with the outcome of patients managed with PCD.

RESUMO

BACKGROUND AND AIM: The two most common etiologies of acute pancreatitis (AP) are alcohol and gallstone. Whether etiology contributes to the outcome in patients with AP is an unresolved issue, more so in the severe form of the disease. The aim is to study the effects of the etiological factors of alcohol and gallstone on the disease course and the role of etiology in the subgroup of severe AP. METHODS: Consecutive patients of AP with alcohol or gallstone etiology were included. Various severity parameters and various outcome measures, such as need for organ support, intensive care, surgical or radiological intervention, hospital stay, and mortality, were evaluated between the two groups. RESULTS: Of the 759 patients, alcoholic pancreatitis was seen in 368 (48.5%), while gallstone disease was observed in 246 (32.4%). Gallstone pancreatitis occurred in older age (P < 0.0001), had a higher female predilection (P < 0.001), and a higher body mass index (P = 0.002) compared to alcohol pancreatitis. Both groups were similar in terms of development of various organ failures and various severity assessment scores. Alcoholic AP had higher rates of necrosis (P = 0.05) and the need for percutaneous catheter drainage (P = 0.02). Outcome measures such as length of hospital stay, need for intensive care, organ support, surgical intervention, or mortality were similar between the two groups. Subset analysis of severe AP (303 patients) showed no difference between the two etiologies with regard to outcome. CONCLUSION: The outcome of AP was independent of the etiology of the disease, alcohol or gallstone, and more so in the severe form of the disease. The number of local complications tends to be slightly higher in the alcoholic group.

RESUMO

BACKGROUND & AIM: Ascites in patients with acute pancreatitis (AP) is understudied although recent literature hints at its evident role in the final outcome. This study was planned to study the characteristics of ascites in patients of AP and its effect on the disease course and outcome. METHODS: Consecutive patients of AP were studied and patients with or without ascites were evaluated for the baseline parameters and severity assessment. Ascites was quantified and fluid analyzed for its characteristics. Intraabdominal pressure (IAP) was monitored. The various outcome parameters were compared between the two groups of patients with and without ascites. RESULTS: Of the cohort of 213 patients, 82 (38.5%) developed ascites. Ascites group had significantly higher rates of organ failure (p = 0.001), necrosis (p=<0.001) and higher severity assessment scores. The ascites group had significantly longer hospital and ICU stay and higher ventilator days compared to the non-ascites group. Mortality was also higher in the ascites group (34.1% vs 8.45; p = 0.001). Majority of patients with ascites had moderate to gross ascites (75.6%), low serum ascites albumin gradient (87.8%) with low amylase levels (71.9%). Sub-group analysis in ascites group showed that patients with fatal outcome had higher rates of moderate to gross ascites, higher baseline IAP and lower reduction in IAP after 48 h. Moderate to gross ascites and grades of intra-abdominal hypertension (IAH) were significant predictors of mortality (AUC - 0.76). CONCLUSION: AP patients with ascites have a more severe disease with poorer outcome. Higher degrees of ascites and IAH grades are significant predictors of mortality.

RESUMO

BACKGROUND: Percutaneous catheter drainage (PCD) is effective initial strategy in the step-up approach of management of acute pancreatitis (AP). The objective of this study was to identify factors associated with outcomes after PCD and develop a predictive model. METHOD AND MATERIALS: In a prospective observational study between July 2016 and Nov 2017, 101 consecutive AP patients were treated using a "step-up approach" in which PCD was used as the first step. We evaluated the association between success of PCD (survival without necrosectomy) and baseline parameters viz. etiology, demography, severity scores, C-reactive protein (CRP), and intra-abdominal pressure (IAP), morphologic characteristics on computed tomography (CT) [percentage of necrosis, CT severity index (CTSI), characteristics of collection prior to PCD (volume, site and solid component of the collection), PCD parameters (initial size, maximum size, number and duration of drainage) and factors after PCD insertion (fall in IAP, reduction in volume of collection). RESULTS: Among 101 patients, 51 required PCD. The success rate of PCD was 66.66% (34/51). Four patients required additional surgical necrosectomy after PCD. Overall mortality was 29.4% (15/51). Multivariate analysis showed percentage of volume reduction of fluid collection (p = 0.016) and organ failure (OF) resolution (p = 0.023) after one week of PCD to be independent predictors of success of PCD. A predictive model based on these two factors resulted in area under curve (AUROC) of 0.915. Nomogram was developed with these two factors to predict the probability of success of PCD. CONCLUSION: Organ failure resolution and reduction in volume of collection after one week of PCD are significant predictors of successful PCD outcomes in patients with fluid collection following AP.

RESUMO

OBJECTIVE: To evaluate the clinical profile and outcome of arterial pseudoaneurysms (PSA) associated with acute and chronic pancreatitis (CP). METHODS: Records of all patients of pancreatitis from 2010 to 2016 were analyzed retrospectively for the development PSAs; clinical profile and outcome parameters were compared between PSAs associated with acute and CP. RESULTS: Of the 980 patients, 46 (all males, age 39.70 ± 11.78 years) developed PSAs, including 19 of 600 of acute pancreatitis (AP) and 27 of 380 of CP. The most common clinical presentation was bleeding (37, 80.4%). The majority of patients was managed nonsurgically, with endovascular embolization in 31 (67.4%) and percutaneous thrombin injection in 9 (19.6%) patients. Pseudoaneurysms in patients with AP were associated more often with fluid collections (94.7% vs. 55.6%, P = 0.004) with more requirement of surgery compared to patients with CP (15.8% vs. 3.7%, P = 0.033). The pattern of arteries involved with PSAs and outcome was similar in AP and CP patients. CONCLUSION: Arterial PSAs were more commonly associated with CP compared to AP with similar presentations. Associated fluid collections and requirement of surgical intervention were higher in PSAs in patients with AP compared to patients with CP.

RESUMO

BACKGROUND AND AIM: To evaluate the role of multiplex polymerase chain reaction (PCR) for diagnosis of gastrointestinal tuberculosis (GITB). METHODS: This was a prospective observational study conducted from July 2015 to November 2016 at a tertiary care teaching institution in north India. Fifty individuals with clinically suspected GITB and older than 18 years of age were recruited. Patients underwent radiological investigations, esophagogastroduodenoscopy, or colonoscopy as clinically indicated. Multiple biopsies for tissue diagnosis and PCR were taken. All specimens were subjected to Ziehl Neelsen staining, histopathology, and multiplex PCR using specific primers for genes IS6110, MPB64, and Protein b. The performance of the assay was assessed using a composite reference standard for diagnosis of tuberculosis. It comprised a combination of clinical characteristics and microbiological methods, including smear, Bactenecin (BACTEC) culture, histopathology, and response to antitubercular therapy. RESULTS: A final diagnosis of tuberculosis was made in 32 cases (Duodenal-4, Ileo-colonic-28). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of histopathology for the diagnosis of tuberculosis was 28.12, 100, 100, and 43.9%, respectively. The sensitivity, specificity, PPV and NPV of BACTEC Mycobacteria Growth Indicator Tube (MGIT) culture for the diagnosis of tuberculosis was 9.3, 100, 100, and 38.29%, respectively. The sensitivity, specificity, PPV, and NPV of multiplex PCR for the diagnosis of tuberculosis was 87.5, 100, 100, and 86.2%, respectively. CONCLUSION: Multiplex PCR using specific primers for genes IS6110, MPB64, and Protein b had a higher sensitivity compared to conventional techniques for the diagnosis of GITB.

RESUMO

OBJECTIVES: Endoscopic ultrasound (EUS) is a minimally invasive pancreatic imaging modality. We evaluated children with idiopathic acute pancreatitis (IAP) and acute recurrent pancreatitis (ARP) for changes of chronicity (Rosemont criteria) and biliary risk factors. Diagnostic yield of simultaneously performed transabdominal ultrasonography (TUS) was compared with EUS. METHODS: This was a prospective observational study. Patients underwent EUS and TUS after 2 months of pancreatitis attack. RESULTS: Forty-five (18 IAP, 27 ARP) patients underwent EUS and TUS. Mean (standard deviation) age and weight were 9.1 (2.6) years and 32.66 (12.43) kg in IAP, whereas these were 12.2 (3.1) years and 44.84 (15.12) kg in ARP, respectively. Endoscopic ultrasound demonstrated morphological abnormality in 33.3% and 40.7% of IAP and ARP, respectively (P = 0.61), whereas 16.6% and 25.9% were abnormal in TUS. Endoscopic ultrasound showed unequivocal changes of chronicity (11.1% vs 0%) and risk factors only among ARP (25.9% vs 0%; P = 0.03) and demonstrated slightly higher odds ratio (95% confidence interval) as compared with TUS to detect abnormalities in both IAP (2.43 [0.49-14.17], P = 0.28) and ARP (1.94 [0.60-6.47], P = 0.26). CONCLUSIONS: Applying EUS, changes of chronicity and risk factors were noted only in ARP. Endoscopic ultrasound performed better than TUS in detecting chronicity.

RESUMO

BACKGROUND & AIMS: Despite recent advances in treatment of viral hepatitis, liver-related mortality is high, possibly owing to the large burden of advanced alcohol-related liver disease (ALD). We investigated whether patients with ALD are initially seen at later stages of disease development than patients with hepatitis C virus (HCV) infection or other etiologies. METHODS: We performed a cross-sectional study of 3453 consecutive patients with either early or advanced liver disease (1699 patients with early and 1754 with advanced liver disease) seen at 17 tertiary care liver or gastrointestinal units worldwide, from August 2015 through March 2017. We collected anthropometric, etiology, and clinical information, as well as and model for end-stage liver disease scores. We used unconditional logistic regression to estimate the odds ratios for evaluation at late stages of the disease progression. RESULTS: Of the patients analyzed, 81% had 1 etiology of liver disease and 17% had 2 etiologies of liver disease. Of patients seen at early stages for a single etiology, 31% had HCV infection, 21% had hepatitis B virus infection, and 17% had nonalcoholic fatty liver disease, whereas only 3.8% had ALD. In contrast, 29% of patients seen for advanced disease had ALD. Patients with ALD were more likely to be seen at specialized centers, with advanced-stage disease, compared with patients with HCV-associated liver disease (odds ratio, 14.1; 95% CI, 10.5-18.9; P < .001). Of patients with 2 etiologies of liver disease, excess alcohol use was associated with 50% of cases. These patients had significantly more visits to health care providers, with more advanced disease, compared with patients without excess alcohol use. The mean model for end-stage liver disease score for patients with advanced ALD (score, 16) was higher than for patients with advanced liver disease not associated with excess alcohol use (score, 13) (P < .01). CONCLUSIONS: In a cross-sectional analysis of patients with liver disease worldwide, we found that patients with ALD are seen with more advanced-stage disease than patients with HCV-associated liver disease. Of patients with 2 etiologies of liver disease, excess alcohol use was associated with 50% of cases. Early detection and referral programs are needed for patients with ALD worldwide.

RESUMO

Background and study aims There is sparse data on the endoscopic management of caustic-induced gastric outlet obstruction (GOO). The present retrospective study aimed to define the response to endoscopic balloon dilatation (EBD) in such patients and their long-term outcome. Patients and methods The data from symptomatic patients of caustic-induced GOO who underwent EBD at our tertiary care center between January 1999 and June 2014 were retrieved. EBD was performed using wire-guided balloons in an incremental manner. Procedural success and clinical success of EBD were evaluated, including complications and long-term outcome. Results A total of 138 patients were evaluated of whom 111 underwent EBD (mean age: 30.79 ±â€Š11.95 years; 65 male patients; 78 patients with isolated gastric stricture; 33 patients with both esophagus plus gastric stricture). The initial balloon diameter at the start of dilatation, and the last balloon diameter were 9.6 ±â€Š2.06 mm (6 - 15 mm) and 14.5 ±â€Š1.6 mm (6 - 15 mm), respectively. Procedural and clinical success was achieved in 95 (85.6 %) and 108 (97.3 %) patients, respectively, requiring a mean (SD) of 5.3 (2.6) and 7.21 (3.86) sessions, respectively. Patients with isolated gastric obstruction had a better response than those with combined esophagus and gastric stricture. Minor complications such as self-limited pain or bleeding were seen in 18 (16.2 %) and 16 (14.4 %), respectively. Perforation occurred in two patients. Over a follow-up period of 98 months, there were no recurrences. Conclusion Caustic-induced GOO can be successfully managed using EBD with 97.3 % clinical success.

RESUMO

BACKGROUND AND AIM: There is lack of data on functional and morphological recovery after an attack of acute pancreatitis (AP) or acute recurrent pancreatitis (ARP) in children. This study aims to evaluate the functional impairment and morphological changes in the pancreas after recovery. METHODS: All consecutive patients presenting with AP (n = 61) or ARP (n = 35), as per standard diagnostic criteria, were enrolled. After 2 months of pancreatitis, fecal elastase-1 (FE-1) (µg/g) and 2-h oral glucose tolerance test to calculate oral disposition index (DIo ) (mmol/L) (ß-cell function) were performed. Morphological changes were assessed by endoscopic ultrasound and transabdominal ultrasound. Patients with chronic pancreatitis (CP) (n = 27) and healthy children (HC) (n = 26) were included as controls for functional parameters. RESULTS: At a median follow up of 12 (4-44) and 11 (2-108) months, 66.7% and 75.9% (P = 0.57) of AP and ARP demonstrated exocrine insufficiency (FE-1 < 200), respectively. Mean (SD) FE-1 was 183.64 ± 150.94 (AP), 135.70 ± 103.80 (ARP), 46.56 ± 30.20 (CP), and 240.00 ± 181.83 (HC) (P < 0.001; anova) (AP vs CP, ARP vs CP, and CP vs HC; P < 0.001). Prediabetes due to insulin resistance was seen in 16.6% and 22.6% (P = 0.56) of AP and ARP. Median (interquartile range) DIo (mmol/L) was comparable between AP (4.20 [2.36, 8.3]) and HC (5.20 [2.89, 8.68]), but was low in ARP (2.97 [1.80, 5.12]), which was comparable with CP (1.91 [1.20, 2.83]). Endoscopic ultrasound demonstrated morphological changes in 25% and 37% (P = 0.34) of AP and ARP, respectively. CONCLUSION: There was high frequency of biochemical evidence of exocrine insufficiency. ß-Cell function (DIo ) was preserved among AP but was poor in ARP. Nearly one-third showed morphological changes in imaging.

RESUMO

Choriocarcinoma is an aggressive gestational trophoblastic neoplasia known for its widely metastatic potential. However, isolated pancreatic metastasis is an extremely rare occurrence and has not been documented in the English literature to the best of our knowledge. The metastatic deposits in the index case led to widespread hemorrhage and necrosis of the pancreatic parenchyma, causing severe acute pancreatitis. The patient succumbed to her illness before chemotherapy was administered. Thus, we present an autopsy case of a uterine choriocarcinoma with isolated pancreatic metastasis presenting as severe acute pancreatitis in a 27-yr-old woman following a molar pregnancy.

RESUMO

BACKGROUND AND OBJECTIVES: Despite improvement in outcomes of acute pancreatitis (AP), some subgroups remain at increased risk. We studied the impact of onset-to-admission interval to a tertiary care centre on outcomes in AP. METHODS: Retrospective analysis of consecutive patients with first episode of AP admitted between 2009 and 2017 on the basis of onset-to-admission interval: ≤7 days, 8-21 days and >21 days was done. Patients were assessed for severity and managed using a step-up approach. Primary outcome measures were surgical necrosectomy and mortality. RESULTS: Of 745 patients (age 39.26 ±â€¯13.18 yrs, 69% male), 380 (51%) had presented ≤7 days, 229 (30.7%) between 8 and 21 days and 136 (18.3%) >21 days after pain onset. Severe pancreatitis was highest in 8-21 days group (129; 56.3%) followed by ≤ 7 days (166; 43.7%) and >21 days of illness (52; 38.2%).Surgical intervention rates were highest in the 8-21 days group(14%) followed by > 21 days (12.5%) and ≤7 days (6.6%) respectively (p = 0.007). Also, mortality was highest in patients with onset to admission interval of 8-21 days (24%) followed by > 21 days (15.4%) and ≤7 days (14.2%) (P = 0.007). On the multivariate analysis, age, late presentation, and the presence of organ failure were found to predict the mortality. CONCLUSION: Patients presenting between 8 and 21 days after onset perform poorly than those presenting earlier or later than them in terms of severity, organ failure, need for surgery and mortality although organ failure remains the most important determinant of outcome. This data can help in devising guidelines for referral of such patients.

RESUMO

BACKGROUND AND AIM: Intestinal dysmotility is considered a risk factor for small intestinal bacterial overgrowth (SIBO). Prokinetics improve intestinal motility and are often prescribed with proton pump inhibitors (PPIs) in patients with gastroesophageal reflux disease (GERD) and/or functional dyspepsia. The present study aimed to evaluate the prevalence of SIBO and the orocecal transit time (OCTT) in patients taking PPI compared with those taking PPI plus prokinetics. METHODS: The study is a single-center, cross-sectional study. Enrolled patients (with age > 12 years) were divided into two groups: patients taking PPIs for more than 3 months (Group A) and those taking PPIs with prokinetics for more than 3 months (Group B) for various indications. Lactulose breath test (LBT) for OCTT and glucose breath test (GBT) for SIBO were conducted for all patients. RESULTS: Of the 147 enrolled patients, SIBO was documented in 13.2% patients in Group A versus 1.8% in Group B, P = 0.018. Median OCTT in Group A was 130 (105-160) min compared with 120 (92.5-147.5) min in Group B (P = 0.010). Median OCTT among SIBO-positive patients was 160 (140-172.5) min compared with SIBO-negative patients, where it was 120 (103.75-150) min (P = 0.002). The duration and type of PPI used were not associated with the occurrence of SIBO in our study. CONCLUSION: The use of prokinetics in patients on PPI may reduce the risk of SIBO by enhancing intestinal motility and may reduce SIBO risk associated with long-term PPI use.
