Case Reports
A Case of Gastric Varices Rupture Due to Splenic Vein Obstruction Associated with Autoimmune Pancreatitis.
A 60-year-old man with a high IgG4 level was found to have pancreatic tail enlargement on computed tomography (CT), and autoimmune pancreatitis (AIP) was confirmed by a histological diagnosis. He was treated with prednisolone for one year and seven months, at which point his treatment finished. ⋯ Endoscopic injection sclerotherapy was performed, and he underwent splenectomy. This case highlights the importance of paying attention to peripancreatic vascular abnormalities during follow-up of AIP patients.

Case Reports
Development of Pancreatic Cancer During the Follow-up of Autoimmune Pancreatitis: A Report of Two Cases.
Autoimmune pancreatitis (AIP) is considered to have a good steroid response and is recognized as a disease with a favorable prognosis. However, it has been reported that patients with AIP have malignant diseases. We herein report two cases of pancreatic cancer during the follow-up of AIP, in which both patients died of pancreatic cancer. Patients with AIP may be at a high risk of malignant diseases, including pancreatic cancer, and medium- to long-term follow-up may be necessary.

Staphylococcus lugdunensis, a minor species of coagulase-negative staphylococci, has attracted attention because of its formidable pathogenicity. We present a case of infective endocarditis (IE) caused by S. lugdunensis in a 72-year-old woman with a history of breast cancer and metastases who presented with fever. ⋯ Transesophageal echocardiography revealed vegetation attached to the right cusp of the aortic valve and an abscess in the annulus, which was less evident on transthoracic echocardiography. This case underscores the importance of considering S. lugdunensis as a potential cause of IE.

Streptococcal toxic shock syndrome (STSS) caused by Streptococcus dysgalactiae subsp. equisimilis (SDSE)-related empyema is rare but can result in shock vitals, acute kidney injury, and extensive erythema. In the present case, a 92-year-old woman with empyema caused by SDSE developed STSS after pleural drainage and antibiotic therapy. Despite temporary improvement with clindamycin and pleural drainage, the patient ultimately died due to malnutrition. Autopsy findings suggested that the infection was well controlled, but infections with Streptococcus spp., including SDSE, can trigger STSS in patients with empyema.

An intrahepatic portosystemic venous shunt (IPSVS) is a rare vascular abnormality, particularly in patients without cirrhosis. An 80-year-old woman without a history of chronic liver disease was admitted to our hospital with hepatic encephalopathy. Computed tomography revealed multiple IPSVSs with two large shunts in segment 6. ⋯ The two large shunts were successfully embolized using detachable coils. Consequently, hyperammonemia and hepatic encephalopathy dramatically improved, and the triphasic wave patterns of the electroencephalogram disappeared. Retrograde transcaval obliteration may be effective for refractory hepatic encephalopathy with IPSVS.
