A 29-year-old man with severe ulcerative colitis and gastroduodenitis was initially treated with oral mesalamine and high-dose intravenous steroid therapy; however, his epigastralgia and vomiting did not improve. After initiating infliximab, the patient experienced prompt improvement in symptoms and inflammation. Although steroids were effective for the colon, they proved ineffective for gastroduodenal lesions, highlighting the necessity for molecular-targeted agents, such as infliximab, in these cases. The timing for administering such agents should be carefully considered.

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.

Case Reports
Pleomorphic Liposarcoma Initially Presenting with Multiple Organ Involvement Including the Heart.
A 42-year-old man visited our hospital due to a gradually swelling subcutaneous mass on the back of the right shoulder. The biopsy specimen was diagnosed pathologically as pleomorphic liposarcoma. ⋯ However, newly developed lung metastases grew rapidly during subsequent cycles of chemotherapy, and the patient died 10 months after the initial diagnosis. The initial presentation of multiple organ involvement, including the heart, is a rare clinical manifestation of pleomorphic liposarcoma.

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.
