RESUMEN

BACKGROUND AND AIMS: Gastric cancer is an extracolonic manifestation of familial adenomatous polyposis (FAP) and is associated with high-risk gastric polyps. There are no known endoscopic criteria to identify these high-risk polyps. Our aim was to develop endoscopic criteria to identify high-risk polyps on endoscopy in FAP. METHODS: We prospectively collected 150 gastric polyps in consecutive patients undergoing surveillance EGD at the Cleveland Clinic. Pictures were taken of each polyp under narrow-band imaging and high-definition white light. In an exploratory phase, 5 endoscopists developed consensus criteria using the images to distinguish high-risk (pyloric gland adenoma, tubular adenoma, hyperplastic) from low-risk (fundic gland with low-grade or no dysplasia) polyps. In the assessment phase, endoscopists were blinded to polyp pathology and used the criteria to predict the individual polyp risk category. To measure diagnostic accuracy, we reported the mean sensitivity, specificity, and interrater agreement (κ). RESULTS: Consensus criteria were developed based on 16 low-risk and 9 high-risk polyps. The final 149 polyps consisted of 128 low-risk and 22 high-risk polyps (1 polyp was excluded from analysis). Using the criteria, the 5 endoscopists distinguished high- from low-risk polyps with a mean sensitivity and specificity of 79% (16.3%) and 78.8% (10.8%), respectively. The κ coefficient was .45, indicating moderate agreement. CONCLUSIONS: We developed endoscopic criteria to distinguish between high- and low-risk polyps associated with gastric cancer in FAP. The criteria provide guidance to endoscopists in targeting high-risk polyps while surveying the stomach of patients with proximal gastric polyposis.

RESUMEN

BACKGROUND: Colonoscopic decompression is performed in inpatients for management of acute colonic pseudo-obstruction. Evidence for its efficacy is limited to small descriptive studies published before the use of neostigmine for acute colonic pseudo-obstruction. Furthermore, therapeutic end points were not defined. OBJECTIVE: The aim was to compare the effectiveness of colonic decompression with standard medical therapy (supportive and pharmacologic therapy) to standard medical therapy alone. DESIGN: This is a retrospective, propensity-matched study. SETTING: The study was conducted at a tertiary care center. PATIENTS: Inpatients with first diagnosis of acute colonic pseudo-obstruction between 2000 and 2016 were selected. INTERVENTIONS: The intervention group received colonic decompression as well as supportive and/or pharmacologic therapy. The control group did not receive colonic decompression. MAIN OUTCOME MEASURES: The primary outcome was the resolution of overall colonic dilation on imaging 48 hours following colonic decompression or the initiation of standard medical therapy alone. Secondary outcomes included symptom improvement, colonic segment diameter percentage change, perforation, 30-day readmission, and all-cause mortality. RESULTS: The standard medical therapy and colonic decompression groups included 61 and 83 patients. Of the patients who underwent colonic decompression, 47.7% had complete resolution of acute colonic pseudo-obstruction versus 19.9% of patients who underwent standard medical therapy (p < 0.001). There were no significant differences in mid or distal colon diameter reduction between groups. The 30-day readmission rate was 15.7% in the colonic decompression group versus 26.2% in the standard medical therapy group. No immediate adverse events were noted in either group. Thirty-day all-cause mortality was 8.4% for the colonic decompression group and 14.8% in the standard medical therapy group. LIMITATIONS: The study was a retrospective review on a highly comorbid population. CONCLUSIONS: Colonic decompression is effective compared to standard medical therapy alone for proximal colonic dilation or symptoms associated with acute colonic pseudo-obstruction. On segmental analysis, colonic decompression does not provide any additional benefit over standard medical therapy in improving transverse or distal colonic dilation.

LA DESCOMPRESIÓN COLÓNICA REDUCE LA PSEUDOOBSTRUCCIÓN COLÓNICA AGUDA PROXIMAL Y LOS SÍNTOMAS RELACIONADOS.: La descompresión colonica se realiza en pacientes hospitalizados para el tratamiento de la pseudoobstrucción colónica aguda. La evidencia de su eficacia se limita a pequeños estudios descriptivos antes del uso de neostigmina para la pseudoobstrucción colónica aguda. Además, los puntos finales terapéuticos no se definieron.El objetivo fue comparar la efectividad de la descompresión colónica mas el tratamiento médico estándar (tratamiento de apoyo y farmacológico) contra el tratamiento médico estándar solamente.Este es un estudio retrospectivo de propensión coincidente.El estudio se realizó en un centro de atención de tercer nivel.Pacientes hospitalizados con diagnóstico de pseudoobstrucción colónica aguda entre 2000 y 2016.El grupo de intervención recibió descompresión colónica, así como tratamiento de apoyo o farmacológica. El grupo control no recibió descompresión colónica.La medida de resultado primaria fue la resolución de la dilatación colónica general en la imagen 48 horas después de la descompresión colónica o el inicio del tratamiento médico estándar solo. Los resultados secundarios incluyeron mejoría de los síntomas, cambio porcentual en el diámetro del segmento colónico, perforación, reingreso a los 30 días y mortalidad por cualquier causa.La terapia médica estándar y los grupos de descompresión colónica incluyeron 61 y 83 pacientes, respectivamente. El 47,7% de los pacientes con descompresión colónica tuvieron una resolución completa de la pseudoobstrucción colónica aguda frente al 19,9% de los pacientes con terapia médica estándar (p < 0,001). No hubo diferencias significativas en la reducción del diámetro del colon medio o distal entre los grupos. La tasa de reingreso a los 30 días fue del 15,7% en el grupo de descompresión colónica frente al 26,2% en el grupo de tratamiento médico estándar. No se observaron eventos adversos inmediatos en ninguno de los dos grupos. La mortalidad por cualquier causa a los 30 días fue del 8.4% para la descompresión del colon y del 14.8% en los grupos de terapia médica estándar.El estudio fue una revisión retrospectiva en una población altamente comórbida.La descompresión colónica es efectiva en comparación con el tratamiento médico estándar solo para la dilatación del colon proximal o los síntomas asociados con la pseudoobstrucción colónica aguda. En el análisis segmentario, la descompresión colónica no proporciona ningún beneficio adicional sobre el tratamiento médica estándar para mejorar la dilatación colónica transversal o distal.

RESUMEN

Background and aims: Acid suppressive therapy (AST) is frequently used after fundoplication. Prior studies show that most patients requiring AST after fundoplication have normal esophageal acid exposure and therefore do not need AST. Our aim was to determine the indications for AST use following fundoplication and the associated factors.Methods: Retrospective analysis of patients who underwent fundoplication at our institution between 2006 and 2013 with pre and postoperative esophageal physiologic studies was performed. Demographic data, symptoms, and findings on high resolution manometry, esophageal pH monitoring and upper endoscopy were collected.Results: Three hundred and thirty-nine patients were included with a median follow up time of 12.8[2.6, 47.7] months. Mean age was 59.6 ± 13.3 years and 71.4% were women. Of those, 39.5% went on AST following fundoplication with a median time to AST use of 15.7[2.8, 36.1] months. The most common reason for AST use was heartburn. Only 29% of patients had objective evidence of acid reflux. Preoperative factors associated with AST use following fundoplication were male gender (HR1.6, p = 0.019), esophageal dysmotility (HR1.7, p = 0.004), proton pump inhibitor use (HR2.3, p < 0.001) and prior history of fundoplication (HR1.8, p = 0.006). In those with paraesophageal hernia repair with Collis gastroplasty (N = 182), esophageal dysmotility (HR1.7, p = 0.047) and NSAID use (HR1.9, p = 0.023) were associated with AST use postoperatively.Discussion: AST use is common after fundoplication. Male gender, preoperative esophageal dysmotility, proton pump inhibitor use and redo fundoplication were associated with AST use following fundoplication. In those undergoing combined Collis gastroplasty, preoperative NSAID use and esophageal dysmotility predicted AST use.

RESUMEN

OBJECTIVES: To describe associations between resident level of training, timing of medication orders, and the types of inpatient medication ordering errors made by internal medicine residents. METHODS: This study reviewed all inpatient medication orders placed by internal medicine residents at a tertiary care academic medical center from July 2011 to June 2015. Medication order errors were measured by pharmacists' reporting of an error via the electronic medical record during real-time surveillance of orders. Multivariable regression models were constructed to assess associations between resident training level (postgraduate year [PGY]), medication order timing (time of day and month of year), and rates of medication ordering errors. RESULTS: Of 1,772,462 medication orders placed by 335 residents, 68,545 (3.9%) triggered a pharmacist intervention in the electronic medical record. Overall and for each PGY level, renal dose monitoring/adjustment was the most common order error (40%). Ordering errors were less frequent during the night and transition periods versus daytime (adjusted odds ratio [aOR] 0.93, 95% confidence interval [CI] 0.91-0.96, and aOR 0.93, 95% CI 0.90-0.95, respectively). Errors were more common in July and August compared with other months (aOR 1.05, 95% CI 1.01-1.09). Compared with PGY2 residents, both PGY1 (aOR 1.06, 95% CI 1.03-1.10), and PGY3 residents (aOR 1.07, 95% CI, 1.03-1.10) were more likely to make medication ordering errors. Throughout the course of the academic year, the odds of a medication ordering error decreased by 16% (aOR 0.84, 95% CI 0.80-0.89). CONCLUSIONS: Despite electronic medical records, medication ordering errors by trainees remain common. Additional supervision and resident education regarding medication orders may be necessary.

RESUMEN

BACKGROUND AND AIMS: Endoscopic ablation therapy has become the mainstay of treatment of Barrett's associated dysplasia and intramucosal cancer (IMC). The widely available techniques for ablation are radiofrequency ablation (RFA) and cryotherapy. Our aim was to compare eradication rates of metaplasia and dysplasia with both these modalities. PATIENTS AND METHODS: Retrospective review of prospectively collected database of patients who underwent endoscopic therapy for Barrett's dysplasia or IMC from 2006 to 2011 was performed. Demographic features, comorbidities, and endoscopic data including length of Barrett's segment, hiatal hernia size, interventions during the endoscopy and histological results were reviewed. RESULTS: Among 154 patients included, 73 patients were in the RFA and 81 patients were in the cryotherapy group. There was complete eradication of intestinal metaplasia (CE-IM) in 81 (52.6%), complete eradication of dysplasia (CE-D) in 133 (86.4%), and persistent dysplasia or cancer in 19 patients (12.3%). Compared to RFA, cryotherapy patients were found to be older and less likely to have undergone endoscopic mucosal resection. On multivariate analysis, patients who underwent RFA had a threefold higher odds of having CE-IM than those who underwent cryotherapy (odds ratio [OR] 2.9, 95% confidence interval [CI] 1.4-6.0, p = 0.004), but CE-D were similar between the two groups (OR 1.7, 95% CI 0.66-4.3, p = 0.28). CONCLUSIONS: Endoscopic therapy is highly effective in eradication of Barrett's associated neoplasia. Patients who underwent cryotherapy were equally likely to achieve CE-D but not CE-IM than patients who underwent RFA. Patient characteristics and preferences may effect choice of treatment selection and outcomes.

RESUMEN

OBJECTIVE: High body mass index (BMI) is a risk factor for Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC). Our aim was to determine if prevalence of dysplasia in BE varies by BMI and study the effect of BMI on progression to high-grade dysplasia (HGD) or EAC. MATERIALS AND METHODS: This is a retrospective review of patients with endoscopic evidence of BE confirmed by presence of intestinal metaplasia on histology from January 2000 to December 2012 at Cleveland Clinic. Patient demographics, BMI and endoscopic findings such as length of BE, dysplasia in BE and size of hiatal hernia were reviewed. Dysplasia was classified as no dysplasia (NDBE), low-grade dysplasia (LGD), HGD and EAC. RESULTS: In this cohort of 1239 patients, average BMI was 29.8 ± 6 kg/m(2). There were 228 (18.4%) in group with BMI <25, 236 (19%) in BMI group 25-27.4, 262 (21.1%) in BMI 27.5-29.9, 303 (24.5%) in BMI 30-34.9, 126 (10.2%) in BMI 35-39.9 and 86 (6.8%) in BMI ≥40. Lower BMI groups had lower prevalence of dysplasia while higher BMI groups had higher prevalence of dysplasia (p = 0.002). During mean follow up of 31.6 ± 26 months, there were 14 cases of HGD/EAC in NDBE group and 29 cases of HGD/EAC in LGD group. BMI or BMI change was not associated with progression to HGD/EAC in NDBE. CONCLUSIONS: High BMI was associated with higher prevalence of dysplasia in BE. But once in a surveillance program, higher BMI is not associated with progression of dysplasia in NDBE.

RESUMEN

BACKGROUND: Patients with gastrointestinal (GI) dysmotility often experience overlapping upper and lower GI symptoms suggestive of multiregional involvement. Wireless motility capsule (WMC) provides a full GI tract transit profile and may be able to detect and diagnose multiregional dysmotility. AIM: To determine the clinical utility and diagnostic yield of WMC in patients with upper and lower GI symptoms suggestive of multiregional GI dysmotility. METHODS: Retrospective chart review of all patients who had undergone WMC testing for suspected multiregional GI dysmotility from January 2009 to December 2012 at our institution was performed. Information regarding demographics, symptoms, medication use, prior diagnostic studies, and results of WMC testing was collected. RESULTS: A total of 161 patients were included in the analysis. Mean age was 43 ± 15 years, and 83 % were female. WMC was abnormal in 109 (67.7 %) subjects. Of these, 17 (15.6 %) patients had isolated delayed gastric emptying, 13 (11.9 %) patients had isolated delayed small bowel transit, and 25 (22.9 %) patients had isolated delayed large bowel transit. Multiregional dysmotility was diagnosed in 54 (49.5 %) patients. There was no significant difference in past medical or past surgical history between patients with isolated regional versus multiregional involvement. The presence or absence of various patient-reported symptoms by history did not predict an abnormal WMC study. CONCLUSIONS: Patients' symptoms are poor predictors of GI dysmotility and its anatomical extent. WMC can be a useful diagnostic test in these patients as it provides a comprehensive evaluation of the motility profile of the entire GI tract and provides objective evidence of multiregional involvement.

RESUMEN

This study investigated the influence of the diluent on the extraction properties of three extractants towards cobalt(ii), nickel(ii), manganese(ii), copper(ii), and lithium(i), i.e. Cyanex® 272 (bis-(2,4,4-trimethylpentyl)phosphinic acid), DEHPA (bis-(2-ethyl hexyl)phosphoric acid), and Acorga® M5640 (alkylsalicylaldehyde oxime). The diluents used in the formulation of the extraction solvents are (i) low-odour aliphatic kerosene produced from the petroleum industry (ELIXORE 180, ELIXORE 230, ELIXORE 205 and ISANE IP 175) and (ii) bio-sourced aliphatic diluents (DEV 2138, DEV 2139, DEV 1763, DEV 2160, DEV 2161 and DEV 2063). No influence of the diluent and no co-extraction of lithium(i), nickel(ii), cobalt(ii), manganese(ii) and aluminum were observed during copper(ii) extraction by Acorga M5640. The nature of the diluent influenced more significantly the extraction properties of manganese(ii) by DEHPA as well as cobalt(ii) and nickel(ii) by Cyanex® 272. Life cycle assessment of the diluents shows that the carbon footprints of the investigated diluents followed the following order: (ELIXORE 180, ELIXORE 230, ELIXORE 205) from petroleum industry > kerosene from petroleum industry > diluent produced from tall oil (DEV 2063) > diluents produced from recycled plastic (DEV 2160, DEV 2161) > diluents produced from used cooking oil (DEV 2138, DEV 2139). By taking into account the physicochemical properties of these diluents (viscosity, flashpoint, aromatic content), the extraction properties of Acorga® M5640, DEHPA, Cyanex® 272 in these diluents and the CO2 footprint of the diluents, this study showed DEV2063 and DEV2139 were the best diluents. A low-carbon footprint solvent extraction flowsheet using these diluents was proposed to extract selectively cobalt, nickel, manganese, lithium and copper from NMC black mass of spent lithium-ion batteries.

RESUMEN

Although the intracellular Cl(-)/H(+) exchanger Clc-5 is expressed in apical intestinal endocytic compartments, its pathophysiological role in the gastrointestinal tract is unknown. In light of recent findings that CLC-5 is downregulated in active ulcerative colitis (UC), we tested the hypothesis that loss of CLC-5 modulates the immune response, thereby inducing susceptibility to UC. Acute dextran sulfate sodium (DSS) colitis was induced in Clcn5 knockout (KO) and wild-type (WT) mice. Colitis, monitored by disease activity index, histological activity index, and myeloperoxidase activity were significantly elevated in DSS-induced Clcn5 KO mice compared with those in WT mice. Comprehensive serum multiplex cytokine profiling demonstrated a heightened Th1-Th17 profile (increased TNF-alpha, IL-6, and IL-17) in DSS-induced Clcn5 KO mice compared with that in WT DSS colitis mice. Interestingly, Clcn5 KO mice maintained on a high vitamin D diet attenuated DSS-induced colitis. Immunofluorescence and Western blot analyses of colonic mucosa validated the systemic cytokine patterns and further revealed enhanced activation of the NF-kappaB pathway in DSS-induced Clcn5 KO mice compared with those in WT mice. Intriguingly, high baseline levels of IL-6 and phospho-IkappaB were observed in Clcn5 KO mice, suggesting a novel immunopathogenic role for the functional defects that result from the loss of Clc-5. Our studies demonstrate that the loss of Clc-5 1) exhibits IL-6-mediated immunopathogenesis, 2) significantly exacerbated DSS-induced colitis, which is influenced by dietary factors, including vitamin D, and 3) portrays distinct NF-kappaB-modulated Th1-Th17 immune dysregulation, implying a role for CLC-5 in the immunopathogenesis of UC.

RESUMEN

Acute pancreatitis represents a disorder characterized by acute necroinflammatory changes of the pancreas and is histologically characterized by acinar cell destruction. Diagnosed clinically with the Revised Atlanta Criteria, and with alcohol and cholelithiasis/choledocholithiasis as the two most prominent antecedents, acute pancreatitis ranks first amongst gastrointestinal diagnoses requiring admission and 21st amongst all diagnoses requiring hospitalization with estimated costs approximating 2.6 billion dollars annually. Complications arising from acute pancreatitis follow a progression from pancreatic/peripancreatic fluid collections to pseudocysts and from pancreatic/peripancreatic necrosis to walled-off necrosis that typically occur over the course of a 4-week interval. Treatment relies heavily on fluid resuscitation and nutrition with advanced endoscopic techniques and cholecystectomy utilized in the setting of gallstone pancreatitis. When necessity dictates a drainage procedure (persistent abdominal pain, gastric or duodenal outlet obstruction, biliary obstruction, and infection), an endoscopic ultrasound with advanced endoscopic techniques and technology rather than surgical intervention is increasingly being utilized to manage symptomatic pseudocysts and walled-off pancreatic necrosis by performing a cystogastrostomy.

RESUMEN

Achalasia is a chronic incurable esophageal motility disorder characterized by impaired lower esophageal sphincter (LES) relaxation and loss of esophageal peristalsis. Although rare, it is currently the most common primary esophageal motility disorder, with an annual incidence of around 1.6 per 100,000 persons and prevalence of around 10.8/100,000 persons. Symptoms of achalasia include dysphagia to both solids and liquids, regurgitation, aspiration, chest pain and weight loss. As the underlying etiology of achalasia remains unclear, there is currently no curative treatment for achalasia. Management of achalasia mainly involves improving the esophageal outflow in order to provide symptomatic relief to patients. The most effective treatment options for achalasia include pneumatic dilation, Heller myotomy and peroral endoscopic myotomy (POEM), with the latter increasingly emerging as the treatment of choice for many patients. This review focusses on evidence for current and emerging treatment options for achalasia with a particular emphasis on POEM.

RESUMEN

Esophageal mucosal calcinosis (EMC) is a rare cause of dysphagia with high morbidity. We present a patient who experienced melena and 3 months of solid and liquid dysphagia along with bilateral lower extremity pain, erythema, and edema later determined to be calcific uremic arteriolopathy (CUA), or calciphylaxis. An esophagogastroduodenoscopy revealed nodularity and linear ulcerations in the upper third of the esophagus. Histology showed active inflammation and ulceration with small foci of subepithelial and intraepithelial calcification consistent with EMC. There is no known treatment for this disorder. Sodium thiosulfate, typically used to treat CUA, did not improve her dysphagia.

RESUMEN

BACKGROUND: Our previous study showed that nephrolithiasis is a common complication in ulcerative colitis patients after ileal pouch anal anastomosis (IPAA). However, the pathogenesis of nephrolithiasis in IPAA patients has not been studied. The aim of this study was to compare urine and serum metabolic compositions in IPAA patients with nephrolithiasis and controls with IPAA and no nephrolithiasis. METHODS: Using cross-sectional study design, serum and 24-hour urine metabolic compositions were compared between IPAA patients with nephrolithiasis (the study group) and those without (the control group). Urinary supersaturation of calcium oxalate, calcium phosphate, and uric acid was calculated. RESULTS: A total of 40 patients were enrolled in the study. There were no significant differences in serum electrolytes, vitamin D, parathyroid hormone, and kidney function tests between the study (n = 20) and control groups (n = 20). Patients in the study group were found to have a significantly higher 24-hour urine supersaturation of calcium oxalate (8.8 versus 5.0, P = 0.037) and calcium phosphate (0.61 versus 0.27, P = 0.028) as compared with controls. Nineteen (95%) patients in the study group were symptomatic due to nephrolithiasis with several requiring procedural intervention for treatment, including ureteroscopy in 3 (15%) patients, lithotripsy in 5 (25%) patients, and percutaneous surgery in 1 (5%) patient. CONCLUSIONS: Ulcerative colitis-IPAA patients are at risk for the development of calcium oxalate and calcium phosphate stones. Nephrolithiasis is symptomatic in a majority of the patients and frequently requires procedural intervention for treatment.

RESUMEN

Barrett's esophagus (BE) is a well-recognized precursor of esophageal adenocarcinoma (EAC) and is defined as ≥1 cm segment of salmon-colored mucosa extending above the gastroesophageal junction into the tubular esophagus with biopsy confirmation of metaplastic replacement of the normal squamous epithelium by intestinal-type columnar epithelium. The incidence of both BE and EAC has been increasing over the past few decades. As a result, preventing the development of BE by identifying and understanding its modifiable and non-modifiable risk factors may help reduce the incidence of EAC. Over the recent past, a tremendous amount of progress has been made towards improving our knowledge of risk factors and pathogenesis of BE.

RESUMEN

BACKGROUND AND AIMS: Superimposed Campylobacter jejuni infection (CJI) has been described in patients with ulcerative colitis (UC). Its risk factors and impact on the disease course of UC are not known. Our aims were to evaluate the risk factors for CJI in UC patients and the impact of the bacterial infection on outcomes of UC. METHODS: Out of a total of 918 UC patients tested, 21 (2.3%) of patients were found to be positive for CJI (the study group). The control group comprised 84 age-matched UC patients who had tested negative for CJI. Risk factors for CJI and UC-related outcomes at 1 year after diagnosis of CJI were compared between the two groups. RESULTS: Ten patients (47.6%) with CJI required hospital admission at the time of diagnosis, including eight for the management of "UC flare". Treatment with antibiotics resulted in improvement in symptoms in 13 patients (61.9%). On multivariate analysis, hospital admission in the preceding year was found to be an independent risk factor for CJI [odds ratio (OR): 3.9; 95% confidence interval (CI): 1.1-14.1] and there was a trend for chronic liver disease as a strong risk factor (OR: 5.0; 95% CI: 0.9-28.3). At 1-year follow up, there was a trend for higher rates of UC-related colectomy (28.8% vs. 14.3%; P = 0.11), and mortality (9.5% vs. 1.2%; P = 0.096) in the study group. CONCLUSION: Recent hospitalization within 1 year was found to be associated with increased risk for CJI in UC patients. There was a trend for worse clinical outcomes of UC with in patients with superimposed CJI, which was frequently associated with UC flare requiring hospital admission.

RESUMEN

OBJECTIVE: Our aim was to assess the risk factors for non-surgery-related portal and mesenteric vein thrombosis (PMVT) and its impact on the outcomes of inflammatory bowel diseases (IBD). METHODS: All patients with a concurrent diagnosis of IBD and PMVT between January 2004 and October 2013 were identified from the electronic medical record (study group; n = 20). Patients were matched for age, sex, and IBD phenotype with control IBD patients who had no PMVT, with a ratio of 1:3 (control group; n = 60). Risk factors for PMVT and IBD-related outcomes at one year after diagnosis of PMVT were compared between the two groups. RESULTS: Of the 20 patients in the Study group, 6 (30%) had UC, 14 (70%) had CD and 11 (55%) were male. On multivariable analysis, inpatient status (odds ratio [OR] 6.88; 95% confidence interval [CI] 1.88-25.12) and baseline corticosteroid use (OR 4.39; 95% CI 1.27-15.19) were found to be independent risk factors for the development of PMVT. At one-year follow-up, PMVT patients were more likely to have an adverse outcome of IBD, including subsequent emergency room visit (26.3% vs. 1.7%; P = 0.003), hospitalization for medical management (60.0% vs. 20.0%; P = 0.001) or IBD-related surgery (65.0% vs. 26.7%; P = 0.003) than the non-PMVT controls. In multivariable analysis, PMVT (OR 5.19; 95% CI 1.07-25.28) and inpatient status (OR 8.92; 95% CI 1.33-59.84) were found to be independent risk factors for poor outcome, whereas baseline immunomodulator use (OR 0.07; 95% CI 0.01-0.51) was found to be a protective factor. CONCLUSIONS: IBD patients who were inpatients or receiving corticosteroid therapy had an increased risk of the development of PMVT. The presence of PMVT was associated with poor clinical outcomes in IBD.

RESUMEN

AIM: To evaluate risk of recidivism on a case-by-case basis. METHODS: From our center's liver transplant program, we selected patients with alcoholic liver disease who were listed for transplant based on Ohio Solid Organ Transplantation Consortium (OSOTC) exception criteria. They were considered to have either a low or medium risk of recidivism, and had at least one or three or more months of abstinence, respectively. They were matched based on gender, age, and Model for End-Stage Liver Disease (MELD) score to controls with alcohol-induced cirrhosis from Organ Procurement and Transplant Network data. RESULTS: Thirty six patients with alcoholic liver disease were approved for listing based on OSOTC exception criteria and were matched to 72 controls. Nineteen patients (53%) with a median [Inter-quartile range (IQR)] MELD score of 24 (13) received transplant and were followed for a median of 3.4 years. They were matched to 38 controls with a median (IQR) MELD score of 25 (9). At one and five years, cumulative survival rates (± standard error) were 90% ± 7% and 92% ± 5% and 73% ± 12% and 77% ± 8% in patients and controls, respectively (Log-rank test, P = 0.837). Four (21%) patients resumed drinking by last follow-up visit. CONCLUSION: Compared to traditional criteria for assessment of risk of recidivism, a careful selection process with more flexibility to evaluate eligibility on a case-by-case basis can lead to similar survival rates after transplantation.

RESUMEN

Ulcerative colitis (UC) is a major form of inflammatory bowel disease (IBD) worldwide. Better understanding of the pathogenesis of UC has led to the development of novel therapeutic agents that target specific mediators of the inflammatory cascade. A number of biological agents have been approved by the U.S. Food and Drug Administration (FDA) for the treatment of UC and several more are currently in various phases of drug development. The commonly used agents include TNFα antagonists (e.g. infliximab, adalimumab, and golimumab) and anti-integrin agents (vedolizumab). These biological agents have profoundly influenced the management of UC patients, especially those with refractory disease. This paper reviews the currently available knowledge and evidence for the use of various biological agents in the treatment of UC.

RESUMEN

Testicular germ cell tumors are the most common malignancy among young men. These are highly chemo-sensitive tumors with high cure rates. More than 95% of patients with testicular cancer present with a painless testicular mass. Here we describe a rare initial presentation of testicular cancer in a previously asymptomatic 22-year-old male who presented with widespread metastatic cannonball lesions in his lungs.
