Background & Aims
Organized screening programs reduce colorectal cancer (CRC) related mortality. Multi-target stool DNA (MT-sDNA) test is an FDA approved screening modality with good compliance and follow-up. In cases of positive MT-sDNA test and negative colonoscopy, experts recommend a 10-year follow-up interval. Concern for interval CRC has led...

Background: The prevalence and significance of digestive manifestations in COVID-19 remain uncertain.
Methods: Consecutive patients hospitalized with COVID-19 were identified across a geographically diverse alliance of medical centers in North America. Data pertaining to baseline characteristics, symptomatology, laboratory assessment, imaging, and...
Chronic massive gastric distention is a rare condition that can occur due to an underlying obstruction or dysmotility. Gastric outlet obstruction (GOO) is often the culprit that can manifest as the result of the luminal, mural, or extrinsic compression. Gastric adenocarcinoma can rarely manifest as massive gastric distention due to partially obstru...
Background: Multitarget stool DNA (MT-DNA) test is an approved modality for colorectal cancer (CRC) screening that has a reported false positive rate 13%. Previous data has not suggested an increase in aerodigestive malignancy after a false positive MT-DNA test, leading
many experts to recommend a 10-year follow-up for CRC screening. However, it is...

Somatostatinoma is a rare neuroendocrine tumor with an incidence rate of 1 in 40 million people. It presents mostly as asymptomatic tumor diagnosed incidentally on imaging or surgery when evaluating or treating possible causes of abdominal pain. It also can present with vague symptoms, or as a clinical triad of glucose intolerance, steatorrhea, and...
Miller Fisher Syndrome (MFS) is a rare variant of Gullian Barre syndrome (GBS) with an incidence of one per one million population. The unique case presented describes a patient who developed MFS that resolved after five days post treatment initiation.
The clinical role of catheter ablation using radiofrequency or cryothermal energy has become an important therapy in the management of patients with recurrent or persistent tachyarrhythmia that is refractory to medical therapy. It is regarded as a safe and reliable procedure and is performed routinely in health care facilities across the country. L...
Pseudomelanosis of the gastrointestinal (GI) tract is a rare condition used to describe the accumulation of pigment deposits in the intestinal mucosa. Its underlying cause is not well understood. It has been described in association with gastrointestinal hemorrhage, chronic kidney disease, hypertension, diabetes mellitus, and medications such as hy...
Acute coronary syndrome (ACS) is a term used to describe a spectrum of diseases associated with sudden reduced blood flow to the heart.
