The present study was performed to describe 2 human cases infected by the horsehair worm, Parachordodes sp., in Japan. Two gordiid worms were collected in the vomit and excreta of an 80-year-old woman in November 2009 in Kyoto city, and in the mouth of 1-year-old boy in December 2009 in Nara city, Japan, respectively. Both worms were males having bifurcated posterior ends and male gonads in cross sectional specimens. They were identified as Parachordodes sp. (Nematomorpha: Chordodidae) based on the characteristic morphologies of cross sections and areoles in the cuticle. DNA analysis on 18S rRNA partial sequence arrangements was also carried out and both worms were assumed to be close to the genus Paragordionus based on tree analysis, and far from Gordius sp. which has already been reported in humans in Japan. DNA sequencing of the Parachordodes worm does not appear on the database; therefore, more information on the gene sequences of the genus Parachordodes from humans, animals, or intermediates is required.

Objective: In recent years, repetitive transcranial magnetic stimulation (rTMS) has shown promise in treating aphasia. While previous reports used the Standard Language Test of Aphasia (SLTA) for evaluation of language functions, the difficulty level of each task in SLTA varies. To show the effects of rTMS in more detail, it is necessary to use weighted values for the SLTA scores. This study aimed to assess the impact of high-frequency rTMS on aphasia using the deviation values of the SLTA.Methods: Thirty-one post-stroke aphasic patients participated in this study [mean (SD) age 58.0 (10.1) years, 15 infarction and 16 hemorrhage] from 2017 to 2021. The average (SD) duration from the onset of stroke to the intervention was 41.1 (31.1) months. Prior to admission, brain sites for rTMS were determined by detecting activation during the word-repeat task using functional MRI. A two-week inpatient treatment, including daily high-frequency rTMS and speech language hearing therapy (excluding Sundays), was conducted. In statistical analysis, SLTA scores were converted into deviation values, with participants grouped by rTMS sites (frontal lobe, temporal lobe, left/right hemisphere) for pre- and post-treatment comparisons.Results: rTMS sites included right frontal lobe (6 cases), left frontal lobe (10 cases), right temporal lobe (5 cases), and left temporal lobe (10 cases). Pre- and post-treatment comparisons showed significant improvements in overall mean scores and speech items in all groups. Additionally, significant enhancements in auditory comprehension items were observed in the right hemisphere and frontal lobe stimulation groups.Conclusion: High-frequency rTMS shows promise that it can improve language function regardless of the stimulation site, and auditory comprehension may be improved specifically by the right hemisphere and left frontal lobe stimulation. This suggests its potential as a valuable therapeutic intervention.
