Laryngeal Histoplasmosis In Patients With Crohn’S Disease Undergoing Treatment With Humira (Adalimumab): A Case Series, Jenna Berg, Jonathan Blecha, Chris Bingcang, Justin Oltman, Jayme Dowdall, Subodh M. Lele

Graduate Medical Education Research Journal

The FDA has advocated for increasing awareness of histoplasmosis for patients undergoing TNF blockers as delay in diagnosis can lead to a poor outcome.1 Laryngeal histoplasmosis is a rare entity that should be part of the differential diagnosis in patients receiving immune suppression for Crohn’s disease. Patients with laryngeal histoplasmosis often report hoarseness, mucosal ulcerations, dysphagia, and odynophagia. We present a series of two cases of laryngeal histoplasmosis in patients with Crohn’s. These cases illustrate the high index of suspicion required to make the diagnosis of laryngeal histoplasmosis, especially in the Midwestern United States. Diagnosis is made quickly and …

Intestinal Microbiota – A Possible Contributor To Cardiovascular Diseases?, Roua Iorga, Ovidiu Gabriel Bratu, Nicolae Bacalbasa, Mihnea-Alexandru Gaman, Camelia Cristina Diaconu

Journal of Mind and Medical Sciences

The intestinal microbiota represents an interesting and emergent field of research, with already known implications in metabolic and immunological functions. Recently, there is increasing evidence that specific gut microbial populations are associated with cardiovascular diseases. Numerous completed and ongoing studies aim to evaluate the potential of intestinal microbiota assessment to improve the prevention, diagnosis, and therapeutic arsenal of cardiovascular diseases, considering dysbiosis as a cardiovascular risk factor. There is strong evidence for a correlation between intestinal flora imbalance and metabolic changes secondary to bacterial metabolites. In this minireview, we discuss recent data about the connections between intestinal microbiota and cardiovascular …

Journal of Mind and Medical Sciences

Hepatitis C virus (HCV) is a pathogenic entity which determines inflammation and liver damage through complex immune mechanisms. Although progress has been made in managing the disease course, chronic infection still remains a significant cause of morbidity and mortality to this day. Because both acute and chronic infection are often asymptomatic, chronic infection is frequently diagnosed when its complications have developed. In a small proportion of cases, the chronic infection does not develop, the immune system managing to cleanse the body from this silent pathogen in the absence of specific treatment, a process called spontaneous viral clearance, which occurs rarely, …

Advanced fibrosis and portal hypertension influence short-term mortality. Lipocalin 2 (LCN2) regulates infection response and increases in liver injury. We explored the role of intrahepatic LCN2 in human alcoholic hepatitis (AH) with advanced fibrosis and portal hypertension and in experimental mouse fibrosis. We found hepatic LCN2 expression and serum LCN2 level markedly increased and correlated with disease severity and portal hypertension in patients with AH. In control human livers, LCN2 expressed exclusively in mononuclear cells, while its expression was markedly induced in AH livers, not only in mononuclear cells but also notably in hepatocytes. Lcn2−/− mice were protected from liver …

Background: Acute pancreatitis (AP) is one of the most common causes of hospital admissions due to gastrointestinal disorders. No pharmacologic agents have been proven to impact the prognosis, and the treatment still remains supportive with intravenous fluids for hydration. Although early hydration has been recommended for the management of mild AP, there is no consensus on the type, rate, and amount of the fluid replacement.

Objective: In this study, we aimed to investigate the outcome of aggressive hydration in patients with AP.

Methods: Retrospective data from patients admitted to 12 hospitals (2015–2017) was used for analysis. Five hundred patients who …


Gastroesophageal Reflux Disease: A General Overview, Julia Fashner Aug 2020

Gastroesophageal Reflux Disease: A General Overview, Julia Fashner

HCA Healthcare Journal of Medicine

Gastroesophageal reflux disease (GERD) varies in presentation and the patient’s symptoms of regurgitation in the throat or epigastric pain do not necessarily correlate with the severity of their disease. This general overview of GERD will include information on guidelines and diagnostic testing; lifestyle, medical and surgical management; and GERD in special populations. The pathophysiology of GERD is multifactorial, and a step-wise approach will assist physicians in making the diagnosis as GERD has a significant financial burden to the U.S. healthcare system.


Urinary Bile Acid Indices As Diagnostic And Prognosic Biomarkers For Liver Diseases, Jawaher Alamoudi Aug 2020

Urinary Bile Acid Indices As Diagnostic And Prognosic Biomarkers For Liver Diseases, Jawaher Alamoudi

Theses & Dissertations

Hepatobiliary diseases result in the accumulation of toxic bile acids (BA) in the liver, blood, and other tissues which may contribute to an unfavorable prognosis. We compared the urinary BA profile between 300 patients with hepatobiliary diseases vs. 103 healthy controls. Also, we investigated the use of the urinary BA profile to develop survival models to predict the prognosis of hepatobiliary diseases. The urinary BA profile, a set of non-BA parameters, and the adverse events of liver transplant and/or death were monitored in patients with cholestatic liver diseases for up to 7 years. The BA profile was characterized by calculating …

Intraductal papillary mucinous neoplasms (IPMNs) and mucinous cystic neoplasms (MCNs) are non-invasive neoplasms that are often observed in association with invasive pancreatic cancers, but their origins and evolutionary relationships are poorly understood. In this study, we analyze 148 samples from IPMNs, MCNs, and small associated invasive carcinomas from 18 patients using whole exome or targeted sequencing. Using evolutionary analyses, we establish that both IPMNs and MCNs are direct precursors to pancreatic cancer. Mutations in SMAD4 and TGFBR2 are frequently restricted to invasive carcinoma, while RNF43 alterations are largely in non-invasive lesions. Genomic analyses suggest an average window of over three …


Recent Advances In The Management Of Gastrointestinal Stromal Tumor., Monjur Ahmed Aug 2020

Recent Advances In The Management Of Gastrointestinal Stromal Tumor., Monjur Ahmed

Division of Gastroenterology and Hepatology Faculty Papers

Gastrointestinal stromal tumor (GIST) is a rare but an important clinical entity seen in our clinical practice. It is the most common mesenchymal tumor of the gastrointestinal tract and most common malignancy of the small intestine. Although the exact prevalence of GIST is not known, the incidence of GIST has been increasing. GISTs arise from interstitial cells of Cajal. Most of the GISTs occur due to mutation in c-kit gene or platelet derived growth factor receptor alpha gene. 15% of GISTs do not have these mutations and they are called wild-type GISTs. Almost all GISTs express KIT receptor tyrosine kinase. …

Low Anterior Resection Syndrome, Theresa H Nguyen, Reena V Chokshi

Faculty, Staff and Students Publications

PURPOSE OF REVIEW: Low anterior resection syndrome is a highly prevalent condition that can develop after anal sphincter-sparing surgery for rectal cancer and impair quality of life. In this review, we summarize the major features and pathophysiology of this syndrome and discuss treatment approaches.

RECENT FINDINGS: Quality of life correlates significantly with severity of low anterior resection syndrome. Prompt assessment and initiation of therapy are essential to rehabilitating damaged mechanical and neural structures. Anorectal manometry demonstrates a global decrease in sphincteric function postoperatively, though in many patients, function does recover. Transanal irrigation, pelvic floor rehabilitation, and biofeedback are the mainstays …


Idiopathic Gastroparesis: Lifestyle Modifications Versus Pharmacotherapy, Rebecca K. Schieffer Aug 2020

Idiopathic Gastroparesis: Lifestyle Modifications Versus Pharmacotherapy, Rebecca K. Schieffer

Theses and Graduate Projects

Idiopathic gastroparesis is a chronic symptomatic motility disorder of the stomach of unknown cause characterized by delayed gastric emptying in the absence of mechanical obstruction, with the majority of gastroparesis cases being classified as idiopathic. Idiopathic gastroparesis continues to be a challenging diagnosis to manage and difficulty remains in treating associated symptoms that result in decreased quality of life. Current non-invasive recommendations for the treatment of idiopathic gastroparesis are lifestyle modifications, including dietary adjustments to follow a gastroparesis diet, and pharmacotherapy prescribed for symptomatic relief. Metoclopramide is currently the only medication approved by the Food and Drug Administration (FDA) in …

Intussusception In An Infant As A Manifestation Of Covid-19, Zorays Moazzam, Areej Saleem, Alina Ashraf, Fyezah Jehan, Muhammad Arshad

Medical College Documents

Gastrointestinal manifestations of COVID-19 are rare and have primarily been limited to diarrhea or vomiting. Intussusception is the most common cause of bowel obstruction in infants, with up to 30% of pediatric intussusception cases having a preceding viral illness. We present the rare case of intussusception in a SARS-CoV-2 positive infant. This is the first documented case of survival in a SARS-CoV-2 positive patient presenting with intussusception as the primary manifestation. As our knowledge of this disease evolves, surgeons need to remain suspicious for possible gastrointestinal manifestations of COVID-19.

PCI Publications and Projects

Globally, colorectal cancer is the third most diagnosed malignancy. It causes significant mortality and morbidity, which can be reduced by early diagnosis with an effective screening test. Integrating artificial intelligence (AI) and computer-aided detection (CAD) with screening methods have shown promising results for colorectal cancer screening. AI could provide a “second look” for endoscopists to decrease the rate of missed polyps during a colonoscopy. It can also improve detection and characterization of polyps by integration with colonoscopy, various advanced endoscopic modalities like magnifying narrow-band imaging, endocytoscopy, confocal endomicroscopy, laser-induced fluorescence spectroscopy, and magnifying chromoendoscopy. In this review, we have discussed …
