Antibiotic use and risk of Clostridioides difficile infection in patients with inflammatory bowel disease.

Background And Aim: Patients with inflammatory bowel disease (IBD) have an increased risk of Clostridioides difficile infection (CDI) compared with those without IBD, which is worsened with antibiotic usage. While prior studies have shown a correlation between CDI development and certain classes of antibiotics, the IBD population has not been well represented. This study evaluates the rates of CDI with outpatient antibiotic use in patients with IBD.

Marginal Artery of Drummond Masquerading as a Fistulous Tract Resulting in Recurrent Lower Gastrointestinal Bleeding.

Lower gastrointestinal bleeding (LGIB) can be caused by a variety of causes. Pseudoaneurysms have been described as a rare etiology of LGIB and are associated with pancreatic pseudocysts that involve adjacent vasculature. Our study describes a 38-year-old man with recent severe coronavirus disease 2019 and necrotizing pancreatitis presenting with hematochezia and blood clots by gastrostomy-jejunostomy.

Jaundice as a presenting symptom of large B-cell lymphoma.

Jaundice can be caused by a wide variety of disorders in adults including pancreatic malignancy. Most pancreatic malignancies are primary in origin. However, other malignancies, including lymphomas, may present as secondary pancreatic masses, with a variety of clinicopathologic features and outcomes for patients.

Multiple rim-enhancing brain lesions and pulmonary cavitary nodules as the presentation of in a patient with non-small cell lung cancer.

Nocardiosis is caused by various strains of the genus a gram-positive, acid-fast bacillus found in organic matter. Disseminated nocardiosis with central nervous system involvement is a rare infection that is most commonly seen in immunocompromised patients. We present a case of a 67-year-old veteran with stage IV adenocarcinoma of the lung undergoing chemotherapy who presented with new cavitary pulmonary lesions.

Hemoglobin Wayne causing a falsely elevated hemoglobin A1c.

Hemoglobin A1c (HbA1c) is an important tool for diagnosis and management of patients with diabetes mellitus (DM). However, hemoglobin variants can interfere with laboratory assays and lead to inaccurate results. This study describes a patient who was found to have falsely elevated HbA1c values secondary to hemoglobin Wayne, a rare hemoglobin variant.
