Background Recently, we reported that the level of lathosterol, a cholesterol synthesis marker, was suppressed after 1 month of treatment with anagliptin, a dipeptidyl peptidase-4 inhibitor. In this study, we administered either anagliptin or miglitol, an alpha-glucosidase inhibitor, for 3 months in patients with type 2 diabetes and compared the lipid-lowering effects of anagliptin with those of miglitol. Methods This study was a 12-week, open-label, prospective, randomized, parallel-group comparison trial. Fifty-two patients with type 2 diabetes who aged 20 – 70 years with a low-density lipoprotein cholesterol (LDL-C) level of over 120 mg/dL, and with no history of treatment with antihyperlipidemic drugs were enrolled. Patients were randomly assigned to either the anagliptin group or miglitol group. The 100 mg of anagliptin was administered twice a day for the anagliptin group and 50 mg of miglitol was administered thrice a day for miglitol group. The changes in lipids, cholesterol synthesis, and absorption markers were evaluated after 12 weeks. Results Fifty-two participants were initially enrolled in the trial, and 47 of them completed the protocol. There was no significant difference in LDL-C, cholesterol synthesis, and the absorption markers between anagliptin and miglitol groups. Conclusions Anagliptin and miglitol are similarly effective on lipid and glycemic control. Copyright 2020, Iijima et al.Background Endoscopic-assisted lumbar decompression is a minimally invasive spine surgery which has been touted to reduce collateral tissue damage, incisional pain, recovery time and complications. Residual back or leg pain and recurrent herniation are commonly reported post-operative outcomes. It has been suggested that injecting orthobiologics like cryopreserved amniotic-derived products (ADPs) and bone marrow aspiration (BMA) into the surgery site would have additional benefit on patient outcomes. This is a Western Institutional Review Board (WIRB)-approved level 1, randomized controlled trial of prospectively collected patient demographic and outcomes data for endoscopic-assisted lumbar decompression surgery. The primary goal of this study was to compare patient outcomes of orthobiologic supplementation during endoscopic-assisted lumbar decompression surgery. Methods Following WIRB approval, 269 patients underwent lumbar endoscopic-assisted decompressive surgery between January 2011 and October 2017. Pati one ADP) re-herniated at the same level. Conclusions Orthobiologic BMA and ADP resulted in improved pain control during early post-operative periods. Copyright 2020, Kamson et al.Eating disorders (EDs) and substance use disorders (SUDs) commonly co-occur, especially in conjunction with affective syndromes, yet little is known about opiate abuse and ED symptoms in patients on naltrexone-bupropion therapy. Moreover, evidence suggests that the opioid system can also be regarded as one of the major systems regulating the anticipatory processes preceding binge eating episodes. The lack of evidence in the effectiveness of psychotherapy treatment in addition to psychotropic mediations compounds the difficulties in stabilizing individuals with EDs. This article aims to exhaustively review literature relating to the use of opioid antagonists in the management of binge eating disorder (BED) and other abnormal eating habits and how this can be augmented by the use of psychological approaches to come up with the most effective therapy or combination of therapies to manage these conditions. Although this approach is promising, it has not been evaluated. A review of the literature pertaining to thecant alterations in eating pattern. This approach for BED may lead to more significant treatment outcomes, but this possibility must be tested in larger samples. Copyright 2020, Valbrun et al.Esophageal carcinoma cuniculatum is a rare variant of squamous cell carcinoma characterized by a unique and common histologic pattern including hyperkeratosis, acanthosis, dyskeratosis, deep keratinization, intraepithelial neutrophils, neutrophilic microabscess, focal cytologic atypia, koilocyte-like cells, and keratin-filled cyst/burrows observed in the resection specimens. Preoperative diagnosis can be extremely difficult. A semiquantitative histologic scoring system has been previously proposed for mucosal biopsies, which has been associated with improved diagnostic yield. However, this histologic schema for the diagnosis of carcinoma cuniculatum has not been applied prospectively. Herein, we describe two cases of esophageal carcinoma cuniculatum in patients presenting with progressive dysphagia and esophageal mass. Presurgical endoscopic mucosal biopsies showed features consistent with carcinoma cuniculatum, and a preoperative diagnosis was achieved by applying the aforementioned semiquantitative histologic schema. Both patients underwent neoadjuvant chemoradiation followed by esophagectomy. Both esophagectomy specimens showed residual adventitia-invading carcinoma cuniculatum, negative lymph nodes, marked tumor regression, and an exuberant histiocytic and giant response. To our best knowledge, these represent the first two cases of esophageal carcinoma cuniculatum diagnosed by applying this semiquantitative histologic schema to mucosal biopsies. Large studies are needed to further confirm these preliminary findings and validate this histologic scoring system. Copyright 2020, Liu et al.Hepatotoxicity caused by chronic oral amiodarone is well documented with around 15-20% incidence rate. However, acute liver failure due to intravenous (IV) amiodarone is rare clinical presentation with 3% incidence rate. Incidence of concomitant renal failure is even rarer. There is no full explanation for the underlying mechanism. Herein, we are presenting a rare case of concomitant acute hepatic failure and acute-on-chronic renal injury induced by use of IV amiodarone. A 67-year-old man with past medical history of coronary artery disease s/p coronary artery bypass graft (CABG), history of alcoholism, and chronic kidney disease stage 3 presented with chest pain for 1 week. In the emergency department (ED), he was found to have atrial flutter. Due to unresponsiveness to IV β-blocker and diltiazem, the patient was loaded with IV amiodarone and continued IV amiodarone drip. His liver function tests (LFTs) and renal functions at the time of administration of IV amiodarone were aspartate transaminase (AST) 176 (rtality. Risk factors include low ejection fraction, hepatic congestion and pre-existing hepatic dysfunction. No obvious underlying mechanism to this presentation has been fully explained. Acute renal failure can be associated with this presentation which is even rarer. Stopping IV amiodarone, administering N-acetylcysteine and good supportive care can lead to favorable outcome. Copyright 2020, Mohamed et al.Background Phlebotomy induces regression of liver fibrosis in genetic hemochromatosis. We assessed the histologic changes in pre-phlebotomy and post-phlebotomy liver biopsies from patients with HFE mutation as a model to study regression of fibrosis. We aimed to show that phlebotomy-induced histologic lesions overlap with porto-sinusoidal vascular disease (PSVD, also known as idiopathic non-cirrhotic portal hypertension), histologically. Methods A total of 51 biopsies (22 pre-phlebotomy and 29 post-phlebotomy) were reviewed, and three variables were studied iron index indicative of the amount of accumulated iron (range 0 to 18), the combined score of vascular changes reflecting the presence of histological lesions that are described in PSVD (range 0 to 9) and the high-grade shunt vessel by calculating the proportion of portal tracts with shunt vessels, with a cutoff of 50%. Two-tailed Student’s t-test and Fisher’s exact test were performed to compare the means of two variables and frequencies of the histologiy distinguished in a limited sample, therefore warranting cautious interpretation in the right clinical context. Copyright 2020, El Jabbour et al.Background Splanchnic venous system thrombosis is a well recognized local vascular complication of acute pancreatitis (AP). It may involve thrombosis of splenic vein (SplV), portal vein (PV) and superior mesenteric vein (SMV), either separately or in combinations, and often detected incidentally, indeed some cases present with upper gastrointestinal bleed, bowel ischemia and hepatic decompensation. Incidence is variable depending on study subjects and diagnostic modalities. Pathogenesis is multifactorial centered on local and systemic inflammation. Management involves treatment of underlying AP and its complications. Universal use of anticoagulation may lead to increased risk of bleeding due to frequent need of interventions (radiologic/endoscopic/surgical). Literature on anticoagulation in setting of AP is sparse and at present there is no consensus guideline on it. Current article details our experience on splanchnic venous thrombosis (SVT) in AP in a well defined cohort of patients at a tertiary care center. Methods Hospitalized patients with AP from January 2018 to December 2018 were included in the study. Detailed information on demographic, clinical, laboratory, radiologic features, and indication of anticoagulation use were collected prospectively during the index admission. Outcome variables were analyzed at the end of 6 months. Results Twenty four out of 105 (22.85%) patients with AP develop SVT. Etiology of AP was alcohol use in 21/24 (87.5%) subjects. Most common vessel involved was isolated SplV in 11/24 (45.8%) patients followed by SplV along with PV and SMV 9/24 (37.50%, P 0.05 with respect to all above variables). Conclusions SVT is commonly seen in alcohol-induced AP. Anticoagulation does not affect outcomes of SVT. Subset of patients may benefit with anticoagulation. Copyright 2020, Junare et al.Background Colonoscopy has been widely used as a diagnostic tool for many conditions, including inflammatory bowel disease and colorectal cancer. Colonoscopy complications include perforation, hemorrhage, abdominal pain, as well as anesthesia risk. Although rare, perforation is the most dangerous complication that occurs in the immediate post-colonoscopy period with an estimated risk of less than 0.1%. Studies on colonoscopy perforation risk between teaching hospitals and non-teaching hospitals are scarce. Methods The National Inpatient Sample database was queried for patients who underwent inpatient colonoscopy between January 2010 and December 2014 in teaching versus non-teaching facilities in order to study their perforation rates. Our study population included 257,006 patients. Univariate regression was performed, and the positive results were analyzed using a multivariate regression module. Results Teaching hospitals had a higher risk of perforation (odds ratio 1.23, confidence interval 1.07 – 1.42, P = 0.004). Perforation rates were higher in females, patients with inflammatory bowel disease and dilatation of strictures. Polypectomy did not yield any statistical difference between the study groups. Other factors such as African-American ethnicity appeared to have a lower risk. Conclusion Perforation rates are higher in teaching hospitals. More studies are needed to examine the difference and how to mitigate the risks. Copyright 2020, Khalid et al.
