Introduction

Acute esophageal necrosis (AEN), commonly referred to as “black esophagus” or Gurvits syndrome, is a rare condition characterized by diffuse black mucosa in the distal esophagus. Most often, the patient is an older male with multiple comorbidities, presenting with upper gastrointestinal bleeding. The exact pathogenesis is unclear, but it is often thought to be secondary to acute vascular hypo-perfusion or ischemia of the esophageal mucosa in critically ill patients with certain secondary comorbid conditions such as renal insufficiency, diabetes mellitus, dyslipidemia, coronary artery disease, malnourishment, alcohol abuse, or association with an underlying malignancy.

The Utility Of Fecal Calprotectin In The Diagnosis And Management Of Microscopic Colitis, Busara Songtanin, Abbie Evans, Kenneth Nugent, Vanessa Costilla

Journal of Community Hospital Internal Medicine Perspectives

Background: The incidence of microscopic colitis has increased over time. To date, there is no specific biomarker for microscopic colitis, and the diagnosis relies on histopathological tissue obtained during colonoscopy which is an invasive and costly procedure. Unlike Crohn’s disease and ulcerative colitis, the utility of fecal calprotectin in diagnosing or monitoring microscopic colitis has not been established, and studies on the role of fecal calprotectin in microscopic colitis are limited. In this retrospective study, we analyzed the utility of this biomarker in the diagnosis of microscopic colitis. Methods: The medical records of patients who have been diagnosed with collagenous …
