Review Case Reports
Mirizzi Syndrome Type IV Successfully Treated with Peroral Single-operator Cholangioscopy-guided Electrohydraulic Lithotripsy: A Case Report with Literature Review.
A 76-year-old man presented with liver dysfunction and intrahepatic bile duct dilatation. Imaging studies showed two large stones that had become impacted in the common hepatic duct, which was fused with the gallbladder. The patient was diagnosed with Mirizzi syndrome type IV. ⋯ The bile flow was temporarily restored; however, the patient experienced cholangitis 16 months later. The stones were extracted via peroral single-operator cholangioscopy (SOC)-guided electrohydraulic lithotripsy. This is the first case in which stones were completely removed by SOC-guided treatment in a patient with Mirizzi syndrome type IV.

Review Case Reports
A Case of a Mild Clinical Phenotype with Myopathic and Hemolytic Forms of Phosphoglycerate Kinase Deficiency (PGK Osaka): A Case Report and Literature Review.
Phosphoglycerate kinase (PGK) deficiency is an X-linked disorder characterized by a combination of hemolytic anemia, myopathy, and brain involvement. We herein report a Japanese man who had several episodes of rhabdomyolysis but was training strenuously to be a professional boxer. Mild hemolytic anemia was noted. ⋯ S62N, was identified in the PGK1 gene. A literature review revealed only one case with a mixed hemolytic and myopathic phenotype like ours. This mild phenotype indicates the complex pathophysiology of PGK deficiency and suggests the benefits of dietary control and exercise.

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease. Lupus nephritis (LN) is a major risk factor for mortality in SLE, and glomerular "full-house" immunofluorescence staining is a well-known characteristic of LN. ⋯ IgA nephropathy or idiopathic FHN was diagnosed, and treatment with steroids was started, after which there was improvement in proteinuria. The prognosis of FHN has been reported to be poor; therefore, aggressive treatment is required for such patients.

A 59-year-old man with progressive cognitive decline and mood disturbances was admitted to the hospital. Brain magnetic resonance imaging revealed marked white matter hyperintensity (WMH) and widespread lobar cerebral microbleeds. ⋯ We diagnosed him with cerebral amyloid angiopathy (CAA) based on the modified Boston Criteria with the rare apolipoprotein E (ApoE) ε2/ε4 genotype. The mechanism underlying reversible leukoencephalopathy in CAA may be related to the loss of autoregulation of brain circulation: cerebrovascular amyloid β deposits damaged the blood-brain barrier of the capillaries, which led to vasogenic edema induced by blood pressure surges.

Endoscopic injection sclerotherapy (EIS) for esophagogastric varices (EGV) was attempted for a 29-year-old man with extrahepatic portal vein obstruction. However, pipeline varices characterized by a large blood flow volume were present, and the sclerosant did not accumulate sufficiently in them. ⋯ Since a reduction in the intravariceal blood flow was achieved by preceding TIO, effective injection of sclerosant into the vessels was possible. For pipeline varices difficult to treat endoscopically, combination therapy with TIO may be effective.
