Metastatic Melanoma Invading the Minor Duodenal Papilla in a Patient With Pancreas Divisum Causing Acute Recurrent Pancreatitis: A Case Report.

Metastasis to the gastrointestinal (GI) tract should always be a consideration when melanoma, particularly metastatic disease, is diagnosed. While metastasis to the small intestine is common, given its rich blood supply, metastasis to the pancreatic ducts is extremely rare. In patients with pancreatic divisum, disease spread to the minor papilla can greatly increase the chance of developing pancreatitis due to the potential for increased pancreatic intraductal pressure.

Unusual Instance of Primary Diffuse Large B-cell Lymphoma of the Colon.

Diffuse large B-cell lymphoma (DLBCL) commonly affects the gastrointestinal (GI) tract, although primary DLBCL rarely occurs in the colon. Primary colorectal lymphoma is a surprisingly rare diagnosis, accounting for a minute percentage of GI lymphomas and colorectal malignancies. We present an interesting case of an immunocompromised young adult female who was diagnosed with DLBCL confined to a cecum polyp after she underwent a colonoscopy for a GI bleed.

Massive Lower Gastrointestinal Hemorrhage as a Complication of Severe Campylobacter Enteritis.

Campylobacter enteritis is typically caused by or and is a major cause of diarrheal illness worldwide. Patients with Campylobacter gastroenteritis can be asymptomatic, but commonly present with a wide range of clinical symptoms including abdominal pain, diarrhea, vomiting, and occasionally self-resolving hematochezia. Although hematochezia can occur, acute massive lower gastrointestinal (GI) bleeding is a rare complication of Campylobacter gastroenteritis and should be considered as a possible differential diagnosis in the presentation of lower GI bleeds.

A Primary Care Approach to Constipation in Adults with Intellectual and Developmental Disabilities.

Constipation is a condition that is very prevalent and is reported in up to 40 percent of individuals with intellectual and developmental disabilities (IDD). Constipation in this patient population is most commonly secondary to neuromuscular abnormalities, immobility, suboptimal diet, and medication side effects. History taking is frequently limited in adults with IDD due to communication barriers, often leading to a missed diagnosis of constipation.

Purulent pericarditis, an unusual cause of cardiac arrest.

Purulent pericarditis is a rare infection of the pericardial space defined by the presence of gross pus or microscopic purulence. Here, we present a case of purulent pericarditis, leading to obstructive and septic shock. After prompt pericardial drainage, the patient experienced rapid improvement in symptoms.

A Prolonged Neurological Presentation of Legionnaire's Disease.

Legionnaire's disease is an uncommon pneumonic disease that can carry a mortality rate up to 20%. It commonly presents as an atypical lower respiratory illness. However, it is important to be mindful of the various extra-pulmonic presentations of the infection.

Upper Gastrointestinal Disorders in Adult Patients with Intellectual and Developmental Disabilities.

The purpose of this literature review is to address the diagnosis and treatment of upper gastrointestinal (GI) disorders in patients with intellectual and developmental disabilities (IDD). Manifestations of upper GI dysmotility and disorders include dysphagia, pulmonary aspiration, malnutrition, gastroesophageal reflux, and gastritis, all of which can impact a person's quality of life and lead to chronic, life-threatening conditions. This article will explore the existing diagnostic methods and treatments for gastrointestinal disorders as they relate to patients with IDD.

Kaolin Clay Anemia.

Iron deficiency anemia is a common diagnosis encountered in the nutrition, primary care, and gastroenterology fields. Iron deficiency anemia most often leads to evaluation for various malabsorption disorders and colonoscopy to exclude colon cancer as an etiology. We present a case of iron deficiency anemia that was caused by geophagia.

Measuring the strength of the horned passalus beetle, Odontotaenius disjunctus: revisiting an old topic with modern technology.

Over a century ago, a pioneering researcher cleverly devised a means to measure how much weight the horned passalus beetle, Odontotaenius disjunctus (Illiger) (Coleoptera: Passalidae), could pull using a series of springs, pulleys, and careful observation. The technology available in modern times now allows for more rigorous data collection on this topic, which could have a number of uses in scientific investigations. In this study, an apparatus was constructed using a dynamometer and a data logger in an effort to ascertain the pulling strength of this species.
