Case Reports
New-onset Refractory Status Epilepticus Involving the Limbic System, Spinal Cord, and Peripheral Nerves.
A healthy 28-year-old woman presented suddenly with intractable status epilepticus: a focal seizure evolved into a generalized seizure preceded by a high fever. Brain magnetic resonance imaging indicated bilateral hyperintensities in the hippocampus on T2-weighted imaging. Electroencephalograms continuously demonstrated diffuse sharp waves and poly-spikes. ⋯ We therefore diagnosed her with cryptogenic limbic encephalitis and new-onset refractory status epilepticus (NORSE). We detected positive anti-ganglioside antibodies, IgG-GQ1b, GD1a, and GT1b, which were negative at six months after the onset. We emphasize the heterogeneous pathogenesis and intractable conditions of NORSE.

Helicobacter pylori can infect the gastric mucosa and cause chronic inflammation, resulting in various diseases, including gastric cancer. Eradication of H. pylori in all infected subjects is recommended; however, the number of H. pylori strains with antibiotic resistance has increased, and the eradication rate has decreased. ⋯ The H. pylori eradication rate with vonoprazan-based triple therapy (vonoprazan, amoxicillin, and clarithromycin) was approximately 90% and had an incidence of adverse events similar to that of PPIs. We review the current situation of H. pylori eradication in Japan, the first country in which vonoprazan was made available.

Spinocerebellar ataxia type 8 (SCA8) is a rare hereditary cerebellar ataxia showing mainly pure cerebellar ataxia. We herein report cases of SCA8 in Japanese monozygotic twins that presented with nystagmus, dysarthria, and limb and truncal ataxia. Their ATXN8OS CTA/CTG repeats were 25/97. ⋯ Some of their pedigrees had nystagmus but not ataxia. These are the first monozygotic twins with SCA8 to be reported anywhere in the world. Although not all subjects with the ATXN8OS CTG expansion develop cerebellar ataxia, these cases suggest the pathogenesis of ATXN8OS repeat expansions in hereditary cerebellar ataxia.

Objective The revised Standards of Medical Care in Diabetes-2018 recommend a less-intensive HbA1c target for elderly individuals than for younger ones. This study aimed to investigate the development and progression of chronic kidney disease (CKD) according to HbA1c levels separately for elderly and middle-aged individuals in a general Japanese population. Methods This was a retrospective cohort study using health checkup data in Iki City, Japan. ⋯ No significant differences in the effects of HbA1c level on the development or progression of CKD were observed between elderly and middle-aged individuals (p>0.3 for interaction). Conclusion The risks of the development and progression of CKD increased from HbA1c levels of 7% in a general Japanese population. Similar associations were observed for both elderly and middle-aged individuals.

Objective Acute abdominal pain (AAP) of diverse etiology is a common chief complaint of patients who present to the emergency department (ED). AAP may pose a diagnostic challenge to physicians in training. We aimed to evaluate whether or not resident trainee doctors examine patients presenting with AAP in a Japanese acute-care hospital following Kendall's diagnostic algorithm. ⋯ Abdominal ultrasonography is one of the recommended examinations for patients with signs of peritoneal irritation, shock or toxic appearance, right lower-quadrant pain, and left upper- or lower-quadrant pain, but the rates were relatively low at 25.0%, 34.4%, 31.8%, and 26.7%, respectively. Conclusion Abdominal ultrasonography required by Kendall's diagnostic algorithm was not performed appropriately in patients with symptoms and signs of peritonitis, shock or toxic appearance, right lower-quadrant pain, and left upper- or lower-quadrant pain or in female patients by resident trainees. Our findings underscore the importance of providing resident doctors with focused training concerning ultrasonography by attending physicians.
