Acute Hepatitis B Infection in a Patient With Confirmed Immunity on Long-Acting Cabotegravir/Rilpivirine.

Long-acting injectable formulation of cabotegravir/rilpivirine (CAB/RPV) is a promising novel maintenance therapy for HIV infection. However, coinfection with active hepatitis B virus (HBV) infection is a contraindication to initiating this therapy. Despite guidelines, patients with HBV immunity can still contract acute HBV infection.

A Rare Case of Malignant Insulinoma Associated With Gastrointestinal Bleed.

A gastrointestinal bleed (GIB) in the setting of metastatic insulinoma is a rare phenomenon. It appears that cases of metastatic insulinoma causing GIB are rare, often influenced by the tumor's location. Our case involves an 82-year-old male with dementia and a history of recurrent hypoglycemia, presenting with an episode of altered mental status.

Gastric Volvulus, An Important Yet Commonly Overlooked Etiology of Upper Gastrointestinal Bleeding: A Case Study.

Gastric volvulus is a distinct and uncommon pathology that usually presents with vomiting secondary to gastric outlet obstruction and gastrointestinal bleeding with an association with hiatal hernia. We present a case of a 71-year-old female who presented to the emergency department (ED) with a three-day history of coffee ground emesis. Of note, the patient was recently in the hospital under medical observation two weeks prior, with similar complaints of hematemesis.

Acute Hemorrhagic Rectal Ulcer Syndrome: A Known Yet Often Overlooked Etiology of Gastrointestinal Bleeding in Chronically Ill Patients.

Acute Hemorrhagic Rectal Ulcer Syndrome (AHRUS) is a known and potentially overlooked cause of severe gastrointestinal bleeding in patients with critical illness. It presents as a sudden and brisk painless bleed. It is common among elderly patients who have chronic conditions such as coronary artery diseases associated with the use of anti-platelets, diabetes mellitus, hypoalbuminemia, liver diseases, sepsis, stroke, and chronic renal failure on hemodialysis.

Image quality of mixed convolution kernel in thoracic computed tomography.

The mixed convolution kernel alters his properties geographically according to the depicted organ structure, especially for the lung. Therefore, we compared the image quality of the mixed convolution kernel to standard soft and hard kernel reconstructions for different organ structures in thoracic computed tomography (CT) images.Our Ethics Committee approved this prospective study.
