A 51-year-old man with a history of renal cell carcinoma presented with sudden aphasia, right hemiparesis, and dysesthesia. MRA showed left middle cerebral artery occlusion, and he was diagnosed with acute ischemic stroke and treated with intravenous recombinant tissue plasminogen activator and endovascular thrombectomy. ⋯ Therefore, a diagnosis of cerebral embolism caused by tumor cells was made. The pathological findings of the retrieved thrombi were important in determining the cause of ischemic stroke.

Objective A pathological acetylcholine (ACh) test was observed at lower ACh doses in females compared with males in European populations. We retrospectively analyzed the sex-related differences in Japanese patients with provoked positive spasm by ACh spasm provocation testing. Methods We performed the ACh spasm provocation tests in 1,854 patients from Jan 1991 until Mar 2019. ⋯ The observed major complications during ACh testing did not differ substantially between the sexes. In addition, the prognosis in females with provoked positive spasm was not different from males. Conclusion Provoked positive spasm by ACh test was obtained at lower mean maximum ACh doses in males compared with females in Japanese patients.

Objective Evidence concerning the safety and efficacy of indacaterol maleate in a real-life setting is limited. The objective of this post-marketing surveillance was to evaluate the real-life safety and efficacy of indacaterol maleate in Japanese patients with chronic obstructive pulmonary disease (COPD). Methods This was a 52-week post-marketing surveillance conducted between April 2012 and December 2018. ⋯ The CAT score decreased, and lung function parameters (FVC, FEV1 and %FEV1) improved across all the COPD stages following treatment with indacaterol. Conclusion Indacaterol showed a favorable safety and tolerability profile in Japanese patients with COPD without new safety signals observed in real-life settings. These findings demonstrated that indacaterol is an effective maintenance treatment in real-life practice for Japanese patients with COPD.
