Stroke in Patients With Common Noncancerous Gynecologic Diseases: A Multicenter Study in Japan.

Background And Objectives: Gynecologic diseases such as uterine fibroids, endometriosis, and adenomyosis are common in women of reproductive age. Case reports and small case series have reported ischemic stroke in women with such common noncancerous gynecologic diseases, and their cause of stroke is frequently attributed to cryptogenic stroke or unconventional mechanisms related to hypercoagulability. However, stroke etiology and prognosis are not well known.

Morphological and molecular studies of Eudiplozoon nipponicum (Goto, 1891) and Eudiplozoon kamegaii sp. n. (Monogenea; Diplozoidae).

Eudiplozoon nipponicum (Goto, 1891) Khotenovsky, 1985 (Monogenea: Diplozoidae), is known to parasitise Cyprinus carpio Linnaeus and species of Carassius. In this study, we conducted a taxonomic re-examination of E. nipponicum using genetic analysis and morphological comparisons from different host species from a single water system.

Usefulness of acceleration time ratio in diagnosis of internal carotid artery origin stenosis.

Purpose: The acceleration time (AcT) ratio of the internal carotid artery (ICA) is increased in ICA stenosis. However, there are few reports that have directly compared the AcT ratio to digital subtraction angiography (DSA) findings.

Methods: We evaluated 177 vessels with DSA and carotid artery ultrasonography.

Increased maximum common carotid intima-media thickness is associated with smoking and hypertension in Tochigi Prefecture residents.

Objective: We investigated maximum intima-media thickness of the common carotid artery (IMT-C) in residents of Tochigi Prefecture, who have been reported to have high stroke mortality.

Method: Our study included 840 individuals. All participants underwent carotid ultrasonography and answered a questionnaire during participation in a health festival in Tochigi Prefecture.

Recurrent juvenile ischemic stroke caused by bow hunter's stroke revealed by carotid duplex ultrasonography.

Bow hunter's stroke (BHS) is a rare cause of vertebrobasilar insufficiency due to rotational vertebral artery (VA) occlusion associated with head turning. We report a juvenile patient presenting with recurrent ischemic stroke caused by BHS, which was revealed by carotid duplex ultrasonography. Carotid duplex ultrasonography performed in the neutral position showed normal findings.
