Case Reports
A Case of Anti-SOX1 Antibody-positive Small-cell Lung Cancer that Triggered Opsoclonus.
A 72-year-old woman with opsoclonus visited our hospital and was diagnosed with small-cell lung cancer. Blood tests revealed anti-SOX1 antibodies, so the patient was diagnosed with paraneoplastic opsoclonus-myoclonus syndrome. ⋯ Anti-Ri and anti-Hu antibodies have been reported as autoantibodies associated with neoplastic opsoclonus-myoclonus syndrome; however, there are no such reports concerning anti-SOX1 antibody. Therefore, this is a valuable case.

We herein report a case of herpes zoster complicated by right-arm paralysis, wherein cervical nerve root ultrasonography enabled the early diagnosis and a therapeutic efficacy evaluation. A 71-year-old man developed progressive weakness in the muscles innervated by the right C5-6 nerve root following the appearance of a painful rash. ⋯ At three weeks following admission, ultrasonography revealed C5-6 nerve root inflammatory swelling improvement. Ultrasonography may aid in the early detection of nerve root inflammatory swelling and help monitor treatment efficacy.

Purulent Pericarditis due to Pneumococcal Bacteremia Caused by Acupuncture: An Autopsy Case Report.
Purulent pericarditis is an infection of the pericardial cavity that produces purulent fluid and is commonly caused by Streptococcus pneumoniae. We herein report an autopsy case that is unique in two respects: the patient had pneumococcal bacteremia from a skin and soft tissue infection associated with acupuncture as well as purulent pericarditis from pneumococcal bacteremia. This case suggests that bloodstream infection should be included in the differential diagnosis on observing pneumococcal pericarditis. Furthermore, it is necessary to recognize that S. pneumoniae may be the organism responsible for skin and soft tissue infections caused by trauma in immunosuppressed patients.

Case Reports
Successful Treatment of Granulomatous-lymphocytic Interstitial Lung Disease in a Patient with CTLA-4 Deficiency.
Common variable immunodeficiency (CVID) causes granulomatous-lymphocytic interstitial lung disease (GLILD) and has a poor prognosis. We herein report a case of GLILD in a 49-year-old woman with CTLA-4 deficiency-associated CVID. The patient presented with dyspnea that had worsened over the past two years. ⋯ A flow cytometric analysis of blood cells and genetic testing confirmed CTLA-4 deficiency. We performed video-assisted thoracoscopic surgery for the pathological diagnosis of GLILD and to exclude infection and malignancy. Corticosteroid treatment successfully improved the condition of the patient.

Revascularization for common carotid artery (CCA) occlusion might be difficult. We reported our strategy for revascularizing CCA occlusion by giant clots. A 94-year-old woman was transferred to our hospital because of right hemiparesis and aphasia. ⋯ We performed mechanical thrombectomy using a 9-Fr balloon-guiding catheter, stent retriever, and aspiration catheter through a 9-Fr long-sheath introducer [long-sheath introducer-assisted revascularization (L-SHARE) technique]. We successfully recanalized CCA occlusion using this method. The L-SHARE technique might be useful for recanalization of CCA occlusion.
