Small Intestinal Arteriovenous Malformation Treated by Double-balloon Endoscopy: A Case Report.
A 42-year-old man was referred to our hospital because of anemia. The patient underwent gastroscopy and colonoscopy, but no bleeding site was detected. Abdominal contrast-enhanced computed tomography (CT) showed vascular dilatation along the wall of the small intestine. ⋯ The AVM was clipped using DBE. After clipping, abdominal contrast-enhanced CT and small bowel angiography revealed the disappearance of the AVM. DBE may be a viable therapeutic option, helping avoid surgery and its associated risks.

A 51-year-old man presented with sudden-onset palpitations and dyspnea that had started 8 h earlier. The patient was restless and tachypneic and had persistent vomiting upon arrival. ⋯ The theophylline level on arrival had been elevated (9.0 μg/mL). Caffeine intoxication should be considered in patients presenting with restlessness, tachypnea, frequent vomiting, lactic acidosis, and electrolyte abnormalities.

Human immunodeficiency virus (HIV)-associated CD8+ T-cell skin infiltrative disease with severe erythroderma has rarely been reported. While HIV-positive patients are prone to develop lymphoma, which is often associated with Epstein-Barr virus, polymorphic lymphoproliferative disorder is rare, accounting for <5% of cases. ⋯ His condition improved significantly with continued antiretroviral therapy. This case suggests that HIV-induced immunodeficiency is central to the pathogenesis of both entities and that improvement of the immunodeficient state is an effective treatment.

Objective To investigate the correlation between pancreatic fat deposition and metabolic syndrome (MetS) parameters, focusing on the locations of fat deposition in the pancreas and sex differences. Methods Degrees of fat deposition in the head, body, and tail of the pancreas were evaluated using computed tomography (CT). We examined the relationships between pancreatic fat deposition and the age, body mass index (BMI), visceral and subcutaneous fat, serum lipid profiles, hepatic steatosis, diabetes mellitus (DM), and hypertension (HTN). ⋯ Conclusion Pancreatic fat deposition, as evaluated by CT, especially in the part of the pancreatic head adjacent to the ampulla of Vater, is a sensitive indicator of MetS. The correlations between pancreatic fat deposition and MetS parameters tended to be stronger in females than in males. These results may help further elucidate the pathophysiology of MetS and provide opportunities for its diagnosis.

A 73-year-old man with a history of heterotaxy syndrome and intestinal malrotation developed hemorrhagic shock due to bleeding from a duodenal ulcer. Esophagogastroduodenoscopy failed to achieve hemostasis because of restriction of the view by massive hemorrhage. Transcatheter arterial embolization cannot achieve endovascular hemostasis due to the vascular anatomy. ⋯ Intestinal malrotation due to heterotaxy syndrome is a risk factor for gastrointestinal bleeding. Severe gastrointestinal bleeding in patients with intestinal malrotation is difficult to control with endoscopy alone. Therefore, combined therapies with endoscopy, interventional radiology, surgical procedures, and intensive care are vital for achieving a better prognosis.
