Imported Hepatitis E Virus Genotype 1: A Rare Case of Acute Hepatitis Managed with Steroid Pulse Therapy.
A 26-year-old Indian man who had arrived in Japan 24 days prior presented to our hospital with abdominal pain and a fever. A blood test revealed marked hepatic dysfunction, and imaging tests confirmed a diagnosis of acute hepatitis. The patient's liver function and coagulability deteriorated, and his general condition was poor. ⋯ Testing revealed positive findings for IgA-hepatitis E virus, and a genetic analysis of hepatitis E identified genotype 1, which is not endemic to Japan, leading to a definitive diagnosis of imported hepatitis E infection from India. The successful response to steroid therapy highlights the potential benefit of this approach in managing severe cases of acute hepatitis E, a rare occurrence in Japan. This case underscores the importance of considering hepatitis E infection in individuals with a recent travel history to regions with high prevalence and the potential benefits of steroid therapy in managing severe cases of acute hepatitis E.

A 59-year-old man presented with esophageal achalasia complicated by lipoid pneumonia. Dysphagia and diffuse ground-glass shadows on computed tomography led to the diagnosis of esophageal achalasia. An analysis of bronchoalveolar lavage (BAL) revealed yellow BAL fluid, with two distinct layers. ⋯ Macrophages that phagocytosed lipids were also observed. He was diagnosed with lipoid pneumonia secondary to esophageal achalasia. His lipoid pneumonia improved after peroral endoscopic myotomy because of the reduction in aspiration risk.

We herein report three cases of steroid-resistant nephrotic syndrome successfully treated with low-density lipoprotein apheresis (LDL-A). All patients were treated with a combination of steroids, cyclosporine, and LDL-A. ⋯ Furthermore, the estimated LDL receptor activity increased, while both serum LDL and total cholesterol levels decreased, suggesting that LDL-A increases LDL receptor activity by driving changes in serum cholesterol concentration. This case series suggests that LDL-A increases LDL receptor activity, which may improve the intracellular uptake of cyclosporine.

Little is known about iatrogenic splenic injury (SI) as an adverse event after colonoscopy. SI is sometimes fatal because of hemorrhaging. We herein report a man who developed SI after colonoscopy. ⋯ His history of left hydronephrosis and insertion with a maximally stiffened scope were suspected as possible risk factors. Endoscopists should consider the possibility of SI when they encounter patients suffering from left-sided abdominal pain after colonoscopy. Careful interview concerning the medical history and gentle maneuvering around the splenic flexure can help avoid SI.

Diaphragmatic hernia with bowel strangulation is a fatal condition requiring a prompt diagnosis. Bochdalek hernia is a common type of diaphragmatic hernia that rarely but occasionally occurs in adults. ⋯ The early diagnosis of strangulated bowel stemming from diaphragmatic hernia can be challenging because of its rarity and the nonspecificity of its symptoms. However, tracing the mesenteric arteries on computed tomography can enable a quick diagnosis.
