Near obstructing painful anorectal mass and facial rash in a man with monkeypox: A case report.

Background: Monkeypox (MPX) is a zoonotic infection that is endemic in Western and Central Africa along the Congo River basin. It has a high case fatality rate especially in younger age groups. It belongs to the virus family orthopoxvirus like smallpox.

Utilization of access to colorectal cancer screening modalities in low-income populations after medicaid expansion.

Background: Colorectal cancer (CRC) remains a relevant public health problem. Current research suggests that racial, economic and geographic disparities impact access. Despite the expansion of Medicaid eligibility as a key component of the Affordable Care Act (ACA), there is a dearth of information on the utilization of newly gained access to CRC screening by low-income individuals.

Acute Hepatitis E Infection Associated With Deer Meat in the United States.

Acute hepatitis E virus (HEV) infection in the United States of America (U.S.A) is low.

Performance of Non-invasive Biomarkers of Liver Fibrosis Amongst Hispanics and African Americans.

Introduction:  Liver biopsy is the gold standard for fibrosis staging. However, it is limited by significant complications. Non-invasive markers of fibrosis have been developed as an alternative to liver biopsy.

Predicting Gastric Intestinal Metaplasia in a High-Risk Population.

Introduction: Gastric intestinal metaplasia (GIM) is a precancerous lesion. It has a low prevalence rate in the United States. However, GIM is more common among non-White and immigrant populations.

Black voices in gastroenterology and hepatology.

The Association of Black Gastroenterologists and Hepatologists (ABGH) was established to improve health equity in Black communities and to provide academic and social support for Black gastroenterologists and hepatologists. In this Viewpoint, four members of ABGH (early career, mid-career and late career) discuss their route into gastroenterology and hepatology, how academia and medicine can promote inclusivity and equity, and their advice to Black students interested in a career in medicine or science.

Ischemic Gastropathy Treated with Celiac Artery Revascularization.

Ischemic gastropathy is an uncommon diagnosis due to extensive arterial collaterals that supply the stomach. The mucosal integrity of the stomach is dependent upon this redundant circulation. Hence, its diagnosis is infrequently entertained in patients presenting with an upper gastrointestinal (GI) bleed.

A Novel Collaborative Community-Based Hepatitis B Screening and Linkage to Care Program for African Immigrants.

Background: Sub-Saharan African nations have among the highest rates of chronic hepatitis B virus (HBV) infection worldwide, but little is known about HBV infection in African-born persons in the United States.

Methods: From October 2011 to July 2013, community-based HBV screenings were conducted targeting persons originating from Africa in New York City. Persons were identified as currently HBV infected (HBsAg positive) or exposed (HBcAb positive).

Spice/K2 synthetic marijuana-induced toxic hepatitis treated with N-acetylcysteine.

Background: Spice/K2 is one of several street names for synthetic marijuana. These hallucinogens are increasingly sold over the internet and in "head" shops. They are usually household herbs that are sprayed with chemicals that become centrally active compounds when burned together and inhaled by smoking.

Case report of acute-on-chronic liver failure secondary to diffuse large B-cell lymphoma.

Acute liver failure is a rare presentation of hematologic malignancy. Acute on chronic liver failure (ACLF) is a newly recognized clinical entity that describes acute hepatic decompensation in persons with preexisting liver disease. Diffuse large B-cell lymphoma (DLBCL) is an aggressive non-Hodgkin's lymphoma (NHL) with increasing incidence in older males, females and blacks.

Esophageal intramural pseudodiverticulosis, a rare cause of food impaction: case report and review of the literature.

Esophageal intramural pseudodiverticulosis (EIPD) is a rare, benign condition of uncertain etiology and pathogenesis, which usually presents with either progressive or intermittent dysphagia. Acute presentation with food impaction, requiring emergency esophago-gastroduodenoscopy (EGD), is rare. We report a case of EIPD presenting as food bolus impaction in an elderly black female.

Simultaneous diagnosis of cryptogenic organizing pneumonia and HIV in a 45 year old man.

Background: Cryptogenic organizing pneumonia (COP) is a small airways disease characterized by intraluminal polyps of myxoid connective tissue which follows a subclinical course and is associated with infectious as well as non infectious processes The concomitant occurrence of human immunodeficiency virus (HIV) infection and COP has rarely been reported. We describe a unique case in which COP was a presenting feature in a patient with newly diagnosed HIV Infection.

Case Report: A 45 year-old man with chronic active smoking presented to the ER with 15 months history of cough productive of minimal whitish sputum without frank or streaks of blood, low grade fever, anorexia and 4-6 lbs weight loss in past 6 months.

Role of interstitial cells of Cajal in motility disorders of the bowel.

Objective: Idiopathic intestinal pseudo-obstruction is characterized by the failure of the intestinal tract to propel its contents appropriately. This leads to signs and symptoms of bowel obstruction and, in the absence of an associated systemic disorder or the administration of drugs known to result in bowel dysmotility, is termed chronic idiopathic intestinal pseudo-obstruction (CIIP). Histopathologically, patients with CIIP can be characterized as having either myopathic or neuropathic forms, but the large majority of patients do not show any specific histological changes.

Perforation of jejunal diverticulum: case report and review of literature.

We report the case of a 90-year-old woman, previously diagnosed with jejunal and colonic diverticula, who presented with left lower quadrant abdominal pain suggesting either colonic diverticulitis or ischemic colitis. A computed tomography scan revealed a perforated jejunal diverticulum with abscess formation. The patient promptly was treated surgically without complications.

The quality of care for Medicare patients with peptic ulcer disease.

Objective: The aim of this study was to examine quality of care for hospitalized Medicare beneficiaries with peptic ulcer disease.

Methods: Collaborating with five Peer Review Organizations, we used 1995 Medicare claim files to select samples of inpatients with a principal diagnosis of peptic ulcer disease. Quality of care indicators developed by content experts included percentages for ulcer patients tested for Helicobacter pylori (H.

Ischemic colitis associated with pseudoephedrine: four cases.

Objective: There is one previously reported case linking ischemic colitis and orally administered nasal decongestants containing pseudoephedrine (MEDLINE 1974-1998). We aimed to document an association between pseudoephedrine ingestion and ischemic colitis.

Methods: We reviewed the cases of four women (ages, 37-50 yr) who presented with the sudden onset of colicky abdominal pain followed by hematochezia.

Regional quantitation of preprodynorphin mRNA in guinea pig gastrointestinal tract.

The endogenous opioid peptide dynorphin has been shown by immunochemical studies to be widely distributed in the gastrointestinal tract. The aim of this study was to determine basal levels of preprodynorphin (ppDyn) mRNA in different regions of the gastrointestinal tract of the guinea pig. A modified sensitive and specific solution hybridization RNase protection assay was used to quantitate ppDyn mRNA, with confirmation by gel analysis of the RNase protected hybrids and PCR amplified cDNA.

Sex, drugs, and infections among youth. Parenterally and sexually transmitted diseases in a high-risk neighborhood.

Background And Objectives: To determine the extent to which youth who reside in households in a neighborhood with large numbers of drug injectors 1) are infected with parenterally or sexually transmitted agents, and 2) engage in high-risk behaviors.

Study Design: A multistage probability household sample survey was conducted in Bushwick, Brooklyn from 1994 to 1995. All households in 12 randomly selected primary sampling units were screened for age-eligible youth.
