Giant Brunner's Gland Adenoma Presenting as Upper Gastrointestinal Bleeding in 76 Years Old Male: A Case Report.

Brunner's gland adenoma is a rare benign tumor of small bowel, often incidentally discovered during endoscopy or radiological imaging. Mostly they are asymptomatic or often present with nonspecific symptoms such as nausea, vomiting, gastrointestinal hemorrhage, iron deficiency anemia. We reported a 76 years old male case presented with chief complaints of vomiting and black tarry stool.

Prolonged Intubation Induced Tracheoesophageal Fistula in Suspected Meningococcal Sepsis with ARDS: A Case Report.

Tracheoesophageal fistula is an abnormal communication between trachea and esophagus. Benign acquired types are rare with the incidence of less than 1%. Prolonged endotracheal intubation remains the most common cause.

Oxygen uptake is more efficient in idiopathic pulmonary arterial hypertension than in chronic thromboembolic pulmonary hypertension.

Background And Objective: The responses of oxygen uptake efficiency (OUE) during cardiopulmonary exercise training (CPET) have not been reported in patients with pulmonary hypertension. We aimed to investigate the differences in OUE between patients with idiopathic pulmonary arterial hypertension (IPAH) and chronic thromboembolic pulmonary hypertension (CTEPH).

Methods: Forty-four patients with IPAH and 29 patients with CTEPH were retrospectively enrolled into our study.

Usefulness of decrease in oxygen uptake efficiency to identify gas exchange abnormality in patients with idiopathic pulmonary arterial hypertension.

Background: Decline in oxygen uptake efficiency (OUE), especially during exercise, is found in patients with chronic heart failure. In this study we aimed to test the validity and usefulness of OUE in evaluating gas exchange abnormality of patients with idiopathic pulmonary arterial hypertension (IPAH).

Methods: We retrospectively investigated the cardiopulmonary exercise test (CPET) with gas exchange measurements in 32 patients with confirmed IPAH.
