Xanthogranulomatous Pyelonephritis: Synchronous Upper And Lower Gastrointestinal Bleed, Muhammad Usman Mirza, John Van Taunay, Muhammad Waleed, Shiva Shankar Vangimalla, Sharana Hegde, Muhamad Alhaj Moustafa

Medical College Documents

Xanthogranulomatous pyelonephritis (XGP) is a rare chronic granulomatous destructive process of the renal parenchyma. It is caused by a chronic inflammatory process due to recurrent urinary tract infections and/or obstructing renal calculi. Rarely, it presents with advanced complications including abscesses and fistula formations. In this article, we report a unique presentation of XGP with simultaneous upper and lower gastrointestinal bleeding in the setting of XGP with reno-gastric and reno-colic fistulas.

Suffering In Silence: Is Gastroparesis Underdiagnosed?, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

In this introduction to Volume 6, Issue 2, the editor-in-chief of the Journal of Patient-Centered Research and Reviews offers additional comment to the clinical review of diabetic gastroparesis authored by Farmer and colleagues (p. 148), regarding the problem of undiagnosed disease. Increased awareness of this entity and appropriate questioning regarding symptoms of diabetic gastroparesis in the primary care setting may prevent the “suffering in silence” experienced by many patients with this complication.

Diabetic Gastroparesis: Perspectives From A Patient And Health Care Providers, Adam D. Farmer, Caroline E. Bruckner-Holt, Susanne Schwartz, Emma Sadler, Sri Kadirkamanthan

Journal of Patient-Centered Research and Reviews

Gastroparesis is defined as a delay in gastric emptying in the absence of mechanical obstruction in the stomach. Gastroparesis has a number of causes, including postsurgical, secondary to medications, postinfectious, idiopathic, and as a complication of diabetes mellitus, where it is underrecognized. The cardinal symptoms of diabetic gastroparesis are nausea, early satiety, bloating, and vomiting. Diabetic gastroparesis is more common in females and has a cumulative incidence of 5% in type 1 diabetes and 1% in type 2 diabetes. It is associated with a reduction in quality of life and exerts a significant burden on health care resources. The pathophysiology …

Endothelial Dysfunction In Adolescents And Young Adults With Nonalcoholic Liver Disease, Cristiana G. Moise, Octavian Istrătoaie, Ionuț Donoiu, Edme R. Mustafa, Georgică C. Târtea, Diana R. Tudorașcu, Ion Rogoveanu

Journal of Mind and Medical Sciences

Nonalcoholic liver disease is a global public health problem that increases cardiovascular morbidity and mortality in these patients. This paper discusses endothelial dysfunction among patients (adolescents and young adults) with nonalcoholic liver disease.

On the one hand, evidence suggests that cardiovascular disease is the leading cause of mortality in patients with advanced nonalcoholic liver disease and that nonalcoholic fatty liver is associated with an increased risk of cardiovascular disease independent of the presence of cardiovascular risk factors and metabolic syndrome components.

On the other hand, nonalcoholic liver disease, especially the non-inflammatory form of nonalcoholic steatohepatitis, may not only be a …

Immune And Inflammatory Pathways In Non-Alcoholic Steatohepatitis (Nash). An Update, Sorina Cezara Coste, Ionela Popovici, Andreea Maria Stefan, Iulia Breaban, Adela Sitar Taut, Simina Tarmure Sarlea, Angela Cozma, Dorel Sampelean, Olga Hilda Orasan, Vasile Negrean, Lucia Maria Procopciuc

Journal of Mind and Medical Sciences

Non-alcoholic steatohepatitis (NASH), also known as fatty liver disease (FLD), is a major public health problem. It is considered to be the hepatic manifestation of the metabolic syndrome. Chronic inflammation of the liver is an essential key in the progression from simple hepatic steatosis to steatohepatitis, the evolutionary stage of fatty liver disease. Moreover, the innate immune system plays a crucial role in the progression of hepatic inflammation. For this reason, it is of utmost importance to elucidate the connections between immune mechanisms, Toll-like receptor cytokine signalling, in order to find new effective treatments. Further studies are necessary to test …

Patient Perception Of Telephone Follow-Up After Resection For Colorectal Cancer: Is It Time For An Alternative To The Out-Patient Clinic?, Marcus Gilmartin, Nicholas Leaver, George Hall, Helena Fawdry, Seung Lee, James Nicholson, Ramya Kalaiselvan, Raj Rajaganeshan

Patient Experience Journal

The economic reality of modern healthcare provides a timely reminder to clinicians of their duty to provide outstanding and cost-effective care. Although multiple guidelines outline investigation, management and surveillance of colorectal cancer, none advocate a particular delivery method. Nurse-led telephone follow-up in multiple specialties has demonstrated equivalent clinical outcomes and patient satisfaction when compared to traditional outpatient department follow-up. This paper aims to compare nurse-led telephone and outpatient follow-up, following surgical resection of colorectal cancer (CRC), focusing on patient perceptions. This cross-sectional study distributed adapted patient satisfaction questionnaire (PS-Q 18) to patients undergoing surveillance following CRC resection via either nurse-led …

The Time Is Now For Mandatory Liver-Focused Clinical Experiences In Medical School., Alexander Y. Pan, Lauren D. Feld, Jeanne M. Farnan, Steven K. Herrine, Adam E. Mikolajczyk

Division of Gastroenterology and Hepatology Faculty Papers

The national burden of chronic liver disease is steadily increasing and is only expected to worsen with the ongoing obesity and opioid epidemics fueling growth in the prevalence of nonalcoholic fatty liver disease and a resurgence of new hepatitis C infections. Our letter highlights the disparity between the rising prevalence of chronic liver disease and the proportion of medical students who receive exposure to patients with liver disease as part of their medical education. A more comprehensive survey of clerkship directors is needed to further corroborate this data, which may lead to reforms in medical school curricula to better address …

Aortoduodenal Fistula Forms From Primary Aortic Stump Graft In A Two-Time Multi-Visceral Transplant Patient With Presentation Of Gastrointestinal Bleed And Bowel Perforation: A Case Report, Brielle Corrente

Graduate Student Research Symposium

Usually not diagnosed until open laparotomy, aortoduodenalfistulas (ADF) are one of the rarest complications of intestinal transplant surgery. With an incidence rate of only 0.04% at autopsy and only 250 documented cases since the early 1800’s, aortoduodenal fistulas are the most deadly complications of intestinal transplantation with a mortality rate of 100% without surgical intervention. A 39 year old, two-time multi-visceral transplant African American female patient suffered from a primary aortoduodenal fistula formation in a primary modified multi-visceral transplant aortic stump graft site. With emergency open laparotomy repair, revascularization of the secondary multi-visceral transplant was performed, saving the life of …

A265 Lymphocytic Esophagitis: A Single Tertiary Center’S Experience With This Emerging Clinical Entity., C Shams, M Co, M Cappell

Conference Presentation Abstracts

Background: Various disorders can produce esophagitis. Lymphocytic esophagitis (LE) has emerged as another clinical entity responsible for esophagitis symptoms. Although increasingly reported pathologically, the clinical characteristics of LE have not been well characterized. Aims: The present study extends the clinicopathologic characterization of LE by comprehensive analysis of 30 affected patients and identifies specific clinical presentations significantly associated with LE. Methods: Thirty patients were identified from January 2000-December 2016 that satisfied diagnostic criteria for LE by lower esophageal biopsy; (1) high concentration of intraepithelial lymphocytes and (2) few granulocytes (ratio of lymphocytes:granulocytes >50:1). Controls, selected from patients undergoing esophagogastroduodenoscopy (EGD) during …

A Rare Case Of Wilson Disease In A 72-Year-Old Patient., Christopher Cao, Timothy Colangelo, Raja Koteswar Dhanekula, Daniel Brandt, Indira Laothamatas, Manish Thapar, Steven K. Herrine, Jesse M. Civan

Division of Gastroenterology and Hepatology Faculty Papers

Wilson disease is an autosomal recessive disorder of abnormal copper metabolism that is prevalent in the younger population, rarely presenting in patients older than 40 years. Clinical presentation may be variable, and diagnosis is often aided by clinical and biochemical tests. We report the case of a 72-year-old woman who presented with acute liver failure initially of unclear etiology. Our patient was initially managed for presumed drug-induced liver injury but ultimately diagnosed with Wilson disease on the basis of clinical presentation, laboratory testing, liver biopsy, quantitative hepatic copper, and abnormal genetic testing.

Nonalcoholic Fatty Liver Disease And The Pnpla3 Gene, Lori Houghton-Rahrig, Debra Schutte, Jenifer I. Fenton, Jennifer Awad

Peer Reviewed Articles

Nonalcoholic fatty liver disease (NAFLD) is a rapidly emerging worldwide public health concern strongly associated with obesity, insulin resistance/diabetes type 2, and the metabolic syndrome (Younossi et al., 2011). It is the most common cause of liver disease in the world (World Gastro - enterology Organisation [WGO], 2012). Defined as a total liver weight comprised of more than 5% fat, NAFLD can progress from simple fatty liver disease to nonalcoholic steatohepatitis with or without fibrosis, liver cirrhosis, liver cancer, or liver failure resulting in premature death (Levene & Goldin, 2012). The development and progression of NAFLD is influenced by genetic …

Understanding Constipation: A Cross-Sectional Study From A Developing Country Setting, Minaz Mawani, Abdul Azeem, Sakina Gheewala, Nazish Butt, Shahab Abid

Section of Gastroenterology

A cross-sectional study was conducted in the Gastroenterology Clinics of The Aga Khan Hospital and Jinnah Postgraduate Medical Centre in Karachi. All patients complaining of constipation were included. Patients with alarm features were excluded. Interviews were conducted by trained doctors using a structured Rome III based pre-tested questionnaire and Bristol Stool Form Scale. Out of 396 participants, 186 (47.0%) had FC and 209 (52.7%) had IBS-C. Based upon Bristol Stool Form Scale, only 214 (54%) reported to have slow transit constipation (BSS <2). A higher proportion of women reported severe form of constipation as compared to men (81.5%, n=150 vs. 65.1%, n=138 p<0.001). However, a higher percentage of men reported using medications to treat their symptoms (71.2%, n=151 vs. 57.1%, n=105 p=0.003). Proper understanding of patient's symptoms is essential for optimizing individual patient management.

Methods: We performed a multicenter retrospective study of patients undergoing EUS-FNB during July 1-November 15, 2016.

Results: Two hundred patients (121 males and 79 females) underwent EUS-FNB of solid lesions with the Acquire needle. Lesions included solid pancreatic masses (n = 109), adenopathy (n = 45), submucosal lesions (n = 34), cholangiocarcinoma (n = …

Unusual Case Of Obstructive Jaundice., Rajesh Essrani Md, Eric Nellis Md, Patrick Hickey Do, Hiral N. Shah Md

Department of Medicine

Most malignant obstructive jaundice arises from primary periampullary tumors and rarely from metastatic cancer of the head and neck. A 60-year-old male was diagnosed with obstructive jaundice due to metastatic squamous cell carcinoma of the tonsil. Only 12 cases of small bowel metastasis from the head and neck have been reported. Most of them originate from laryngeal squamous cell carcinoma, and only one case reported tonsillar cancer metastasizing to the ileum. Our case is the first one, to the best of our knowledge, to illustrate tonsillar cancer with metastasis to the duodenum causing obstructive jaundice.

A Comparison Of The Diagnosis Of Gastroparesis In 4 H Pediatric Gastric Emptying Studies Versus 2 H Studies., Sarah T. Edwards, Jose Cocjin, Stephanie B. Theut, Douglas C. Rivard, Ashley K. Sherman, Craig A. Friesen

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: In adults, there is a consensus for standards to diagnose gastroparesis utilizing a gastric emptying study as the key diagnostic modality but there is no consensus for a standard in pediatrics. Additionally, some cost savings might be achieved if symptoms could be utilized to predict patients with gastroparesis. The aims of the current study were to confirm the sensitivity of a 4 h study in the pediatric population and to assess whether the severity of symptoms were predictive of delayed gastric emptying.

STUDY: This was a single site, two part study. In the first part, results were reviewed for …

Identification Of Novel Regulatory Genes In Apap Induced Hepatocyte Toxicity By A Genome-Wide Crispr-Cas9 Screen., Katherine Shortt, Daniel P. Heruth, Nini Zhang, Weibin Wu, Shipra Singh, Ding-You Li, Li Qin Zhang, Gerald J. Wyckoff, Lei S Qi, Craig A. Friesen, Shui Qing Ye

Manuscripts, Articles, Book Chapters and Other Papers

Acetaminophen (APAP) is a commonly used analgesic responsible for more than half of acute liver failure cases. Identification of previously unknown genetic risk factors would provide mechanistic insights and novel therapeutic targets for APAP-induced liver injury. This study used a genome-wide CRISPR-Cas9 screen to evaluate genes that are protective against, or cause susceptibility to, APAP-induced liver injury. HuH7 human hepatocellular carcinoma cells containing CRISPR-Cas9 gene knockouts were treated with 15 mM APAP for 30 minutes to 4 days. A gene expression profile was developed based on the 1) top screening hits, 2) overlap of expression data from APAP overdose studies, …
