Cryoballoon ablation has been established as an effective method for pulmonary vein isolation and has recently been investigated for its efficacy of substrate modification on the left atrial roof area in patients with persistent atrial fibrillation. We herein report the first successful case of left atrial posterior wall isolation including roof line ablation using cryoballoons in a patient with persistent atrial fibrillation, dextrocardia, and situs inversus. Cryoballoon ablation proved to be a safe and straightforward approach to create lasting lesions along the left atrial roof line and left atrial posterior wall, even under challenging anatomical conditions.

We herein report a 67-year-old Japanese woman with liver cirrhosis caused by primary biliary cholangitis. The patient was admitted to the hospital with loss of consciousness. ⋯ The test results indicated sequence similarity between urease-positive S. salivarius in both oral saliva and stool, as revealed by the signals in the overlapping peaks. This bacterium can potentially increase ammonia production in the gut, leading to HE in patients with liver cirrhosis.

A 19-year-old Japanese man was referred for a further evaluation of liver dysfunction. Despite the absence of symptoms or obesity, the liver biopsy results were consistent with non-alcoholic steatohepatitis. ⋯ A previously unreported variant, i.e., c.3866A>T (p. Asp1289Val) was detected on the patient's other allele and was considered a novel mutation, classified as 'likely pathogenic' according to the American College of Medical Genetics guidelines.

Rosai-Dorfman disease (RDD) is a rare form of non-Langerhans cell histiocytosis. Although 20% of patients with RDD have spontaneous remission, some cases with central nervous system (CNS) involvement require surgery or systemic treatment. ⋯ Repeated intravenous methylprednisolone (IVMP) administration resolved and stabilized the hypertrophic pachymeningitis without any sequelae. If surgery or anticancer medications are contraindicated, repeated IVMP may be a good therapeutic option for CNS-associated RDD.

We herein report a 47-year-old man who presented with progressive paraparesis. Imaging revealed a right upper pulmonary nodule, massive bilateral adrenal metastases, thoracolumbar vertebral osteolysis, and subcutaneous nodules. ⋯ Autopsy findings confirmed pulmonary pleomorphic carcinoma with extensive metastases. Quantification of chromosomal rearrangements revealed a jump-up mutation from the normal karyotype, followed by a further incremental increase in the degree of deviation.
