A Rare Case of Sigmoid Colon Perforation in a Patient With Severe Acute Pancreatitis.

Severe acute pancreatitis can cause systemic inflammation and multiorgan failure. We present the case of a 60-year-old woman who presented with necrotizing pancreatitis and subsequently developed a sigmoid colon perforation. The perforation presumably occurred because of extravasation of pancreatic enzymes into the abdominal cavity, resulting in colonic wall injury. Our case highlights the rare colonic complications of severe acute pancreatitis.

Corticosteroids to safely reduce neonatal respiratory morbidity after late preterm and term planned caesarean section birth? A randomised placebo-controlled feasibility study.

OBJECTIVES: To assess the feasibility of conducting a randomised placebo-controlled trial of corticosteroids prior to planned caesarean section from 35+0 to 39+6 weeks. DESIGN: A triple-blind, placebo-controlled, parallel, trial randomised at the participant level (1:1 ratio). Additional feasibility data obtained by questionnaires from trial participants and women who declined trial participation, and focus groups with local site researchers and clinicians. SETTING: Three obstetric units in New Zealand including tertiary and secondary care; public and private care, and research active and non-active units. PARTICIPANTS: Women undergoing a planned caesarean section from 35+0 to 39+6 weeks; local site researchers and clinicians. INTERVENTIONS: Two doses of 11.4 mg betamethasone or saline placebo. Questionnaires and focus group meetings. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome: trial recruitment rate of eligible women. SECONDARY OUTCOMES: trial recruitment by gestational age, site and delivery indication; proportion of babies who completed measurements of blood glucose concentrations as per protocol; overall incidence neonatal respiratory distress requiring >60 min of respiratory support; overall incidence of neonatal hypoglycaemia, and barriers and enablers to trial participation by participants, researchers and clinicians. RESULTS: The recruitment rate was 8.9% (88/987) overall and 11.2% (88/789) for those approached about the trial. Neonatal blood glucose concentrations were measured as per protocol in 87/92 (94.6%) babies. For potential participants, key enablers to participation were contributing to research, a feeling of relevance and a good understanding; key barriers were a lack of understanding and concerns over safety. For researchers and clinicians, themes representing enablers and barriers included relevance, communication and awareness, influences on women's decision-making, resource challenges and trial process practicalities. CONCLUSIONS: Some women are willing to participate in a randomised placebo-controlled trial of corticosteroids prior to a planned caesarean section birth at late preterm and term gestations. Participation in such a trial can be enhanced.

Safety and efficacy of percutaneous transabdominal and transesophageal decompression gastric catheters for palliation of malignant bowel obstruction.

PURPOSE: To evaluate the safety and primary technical success rate of gastric decompression via percutaneous transabdominal gastrostomy (PTAG) or percutaneous transesophageal gastric (PTEG) catheter placement for management of malignant bowel obstruction (MBO). A secondary purpose was to evaluate the safety and success rate for PTAG catheter placement in patients with both MBO and ascites. METHODS: A single-institution retrospective review of 385 patients who underwent attempted decompression gastric catheter placement from March 2013 to August 2018 was performed. Medical records and imaging studies were reviewed. A subgroup of patients with concomitant MBO and ascites were identified. The primary outcome measures were procedural technical success and procedural complications. RESULTS: 394 decompression gastrostomy catheters were attempted from 2013 to 2018, n = 353 PTAG and n = 41 PTEG. The success rate was 95.5% (n = 337 of 353) for PTAG and 97.6% (n = 40 of 41) for PTEG. There were 63 total complications involving 47 (13.9%) patients following PTAG and 13 total complications involving 9 (22.5%) patients following PTEG, P = 0.16. For the subgroup of patients with MBO and ascites, the success rate was 94.8% (n = 182 of 192 patients), and there were 20 complications involving 17 (12.9%) of 132 patients. CONCLUSION: Gastric decompression for patients with MBO via PTAG or PTEG catheter placement is associated with high success rates and low complications.

Seasonal and gestational variation in perinatal depression in a prospective cohort in New Zealand.

BACKGROUND: Perinatal depression has wide-ranging impacts on the health of mothers, babies and their families. Previously published data suggest seasonal variation in the prevalence of perinatal depression, as well as possible variation with gestation. AIMS: To describe the prevalence of perinatal depression in a New Zealand population; to describe the trend in depression over gestational age; and to assess the influence of season on perinatal depression. MATERIALS AND METHODS: We performed a secondary analysis of data from a prospective cohort of 260 women in Dunedin, New Zealand. Edinburgh Depression Scores were collected at four antenatal time points and at six months postpartum. RESULTS: Prevalence of depression decreased from 8.1% to 4.6% antenatally, and to 6.6% postnatally, but the variation was non-significant. Prevalence was significantly higher in winter and spring antenatally (odds ratio (OR) 3.15, 95% CI 1.01-9.82 and OR 3.16, CI 1.05-9.55), and in spring postnatally (OR 8.40, 95% CI 1.01-69.52) compared to autumn. Antenatal depression was associated with poor sleep quality (OR 4.27, 95% CI 1.22-14.93), while postnatal depression was associated with caesarean delivery (OR 5.03, 95% CI 1.29-19.64). CONCLUSIONS: This is the first NZ cohort to assess depression over multiple antenatal and postnatal time points. A significantly higher rate of depression was identified in winter and spring antenatally and in spring postnatally, corresponding to a higher risk of postnatal depression with autumn deliveries. These findings should prompt greater awareness at these higher risk time periods.

A Systematic Review of the Effectiveness of Psychological Treatments for IBS in Gastroenterology Settings: Promising but in Need of Further Study.

BACKGROUND: Psychological treatments are efficacious for irritable bowel syndrome (IBS) in clinical trials; however, their effectiveness when conducted in gastroenterology practice settings is unclear. AIM: To perform a systematic review of the types and effects of psychological treatments for IBS conducted in gastroenterology clinics. METHODS: We searched PubMed, EMBASE, and Cochrane central register. Studies conducted in gastroenterology clinic settings with IBS patients who were clinically referred from gastroenterology were included. RESULTS: We identified 3078 citations, of which only eight studies were eligible. Seven studies compared psychological treatments (average n = 25.7; range 12-43) to controls (average n = 25.4 patients; range 12-47), whereas one study compared two active "bonafide" interventions. Psychological treatments varied (cognitive-behavioral therapy, guided affective imagery, mindfulness, hypnosis, biofeedback, emotional awareness training). However, across approaches, short-term benefits were seen. IBS symptoms improved significantly among patients in cognitive and behavioral therapies, mindfulness-based stress reduction, guided affective imagery, and emotional awareness training compared with controls; there was a similar trend for gut-directed hypnotherapy. Similarly, IBS symptoms improved in a study of two active biofeedback and hypnosis treatments. CONCLUSIONS: Evidence for the effectiveness of psychological treatment in gastroenterology practice is promising but limited. Study designs that involve a blending of efficacy and effectiveness components are needed.

Physician Burnout: The Hidden Health Care Crisis.

Physician burnout is an under-recognized and under-reported problem. Characterized by a state of mental exhaustion, depersonalization, and a decreased sense of personal accomplishment, burnout may affect more than 60% of family practice providers and at least one third of gastroenterologists. Some studies have shown that younger physicians, physicians performing high-risk procedures, and physicians experiencing work-life conflicts are at greatest risk. If unrecognized, the costs to the physician and to the health care system can be enormous because physician burnout is associated with increased rates of depression, alcohol and drug abuse, divorce, suicide, medical errors, difficult relationships with coworkers, and patient dissatisfaction, as well as physician attrition. If properly recognized, appropriate treatments are available. This article presents a case study of a physician suffering from burnout, reviews how burnout is defined, identifies those providers at greatest risk, discusses root causes, and outlines a treatment program.

Pancreatic enzyme replacement therapy for pancreatic exocrine insufficiency in the 21(st) century.

Restitution of normal fat absorption in exocrine pancreatic insufficiency remains an elusive goal. Although many patients achieve satisfactory clinical results with enzyme therapy, few experience normalization of fat absorption, and many, if not most, will require individualized therapy. Increasing the quantity of lipase administered rarely eliminates steatorrhea but increases the cost of therapy. Enteric coated enzyme microbead formulations tend to separate from nutrients in the stomach precluding coordinated emptying of enzymes and nutrients. Unprotected enzymes mix well and empty with nutrients but are inactivated at pH 4 or below. We describe approaches for improving the results of enzyme therapy including changing to, or adding, a different product, adding non-enteric coated enzymes, (e.g., giving unprotected enzymes at the start of the meal and acid-protected formulations later), use of antisecretory drugs and/or antacids, and changing the timing of enzyme administration. Because considerable lipid is emptied in the first postprandial hour, it is prudent to start therapy with enteric coated microbead prior to the meal so that some enzymes are available during that first hour. Patients with hyperacidity may benefit from adjuvant antisecretory therapy to reduce the duodenal acid load and possibly also sodium bicarbonate to prevent duodenal acidity. Comparative studies of clinical effectiveness of different formulations as well as the characteristics of dispersion, emptying, and dissolution of enteric-coated microspheres of different diameter and density are needed; many such studies have been completed but not yet made public. We discuss the history of pancreatic enzyme therapy and describe current use of modern preparations, approaches to overcoming unsatisfactory clinical responses, as well as studies needed to be able to provide reliably effective therapy.

Abdominopelvic and lower extremity deep venous thrombosis: evaluation with contrast-enhanced MR venography with a blood-pool agent.

OBJECTIVE: The purpose of this article is to evaluate contrast-enhanced (CE) MR venography (MRV) with a blood-pool agent for detection of abdominopelvic and lower extremity deep venous thrombosis (DVT) compared with a conventional unenhanced gradient-recalled echo (GRE) MRV technique. MATERIALS AND METHODS: This retrospective study was performed on 30 patients (mean age, 52.7 years; 15 men and 15 women) referred for MRV between March 2010 and November 2010 for evaluation of lower extremity or abdominopelvic DVT. All patients underwent a GRE sequence followed by a CE T1-weighted sequence with gadofosveset, a blood-pool agent. The abdominopelvic and lower extremity venous system was divided into 13 segments. The presence of acute or chronic DVT was assessed by six radiologists, as well as qualitative and quantitative assessments of each venous segment. Image acquisition and interpretation times were also tabulated. RESULTS: The sensitivity and specificity for acute DVT were 91.0% and 99.8%, respectively, on CE MRV compared with 80.8% and 95.8%, respectively, on GRE MRV (p = 0.077 and p < 0.001). The sensitivity and specificity for chronic DVT were 84.4% and 98.4%, respectively, on CE MRV and 64.5% and 95.6%, respectively, on GRE MRV (p < 0.001 for both). Subjective ratings of vein visualization, signal homogeneity, and confidence pertaining to DVT diagnosis were significantly higher with the CE images (p < 0.001). The contrast-to-noise ratio for CE images was similar or significantly higher for all venous segments. Image acquisition and radiologist interpretation times on the CE studies were decreased (p < 0.001). CONCLUSION: Gadofosveset-enhanced MRV had equal or higher sensitivity and specificity for detection of DVT than did GRE MRV, with decreased time for image acquisition and interpretation.

Comparative effectiveness of i-SCAN™ and high-definition white light characterizing small colonic polyps.

AIM: To evaluate accuracy of in vivo diagnosis of adenomatous vs non-adenomatous polyps using i-SCAN digital chromoendoscopy compared with high-definition white light. METHODS: This is a single-center comparative effectiveness pilot study. Polyps (n = 103) from 75 average-risk adult outpatients undergoing screening or surveillance colonoscopy between December 1, 2010 and April 1, 2011 were evaluated by two participating endoscopists in an academic outpatient endoscopy center. Polyps were evaluated both with high-definition white light and with i-SCAN to make an in vivo prediction of adenomatous vs non-adenomatous pathology. We determined diagnostic characteristics of i-SCAN and high-definition white light, including sensitivity, specificity, and accuracy, with regards to identifying adenomatous vs non-adenomatous polyps. Histopathologic diagnosis was the gold standard comparison. RESULTS: One hundred and three small polyps, detected from forty-three patients, were included in the analysis. The average size of the polyps evaluated in the analysis was 3.7 mm (SD 1.3 mm, range 2 mm to 8 mm). Formal histopathology revealed that 54/103 (52.4%) were adenomas, 26/103 (25.2%) were hyperplastic, and 23/103 (22.3%) were other diagnoses include "lymphoid aggregates", "non-specific colitis," and "no pathologic diagnosis." Overall, the combined accuracy of endoscopists for predicting adenomas was identical between i-SCAN (71.8%, 95%CI: 62.1%-80.3%) and high-definition white light (71.8%, 95%CI: 62.1%-80.3%). However, the accuracy of each endoscopist differed substantially, where endoscopist A demonstrated 63.0% overall accuracy (95%CI: 50.9%-74.0%) as compared with endoscopist B demonstrating 93.3% overall accuracy (95%CI: 77.9%-99.2%), irrespective of imaging modality. Neither endoscopist demonstrated a significant learning effect with i-SCAN during the study. Though endoscopist A increased accuracy using i-SCAN from 59% (95%CI: 42.1%-74.4%) in the first half to 67.6% (95%CI: 49.5%-82.6%) in the second half, and endoscopist B decreased accuracy using i-SCAN from 100% (95%CI: 80.5%-100.0%) in the first half to 84.6% (95%CI: 54.6%-98.1%) in the second half, neither of these differences were statistically significant. CONCLUSION: i-SCAN and high-definition white light had similar efficacy predicting polyp histology. Endoscopist training likely plays a critical role in diagnostic test characteristics and deserves further study.
