Sensory and motor neuropathy of the trigeminal nerve due to trauma is quite rare. Furthermore, there have been no detailed reports on occlusal abnormalities and trismus associated with post-traumatic trigeminal motor neuropathy. Here, the authors report a case of trigeminal motor neuropathy and trigeminal sensory neuropathy in all 3 divisions caused by an orbital stab wound. During kendo practice, a 61-year-old man was injured in his right medial canthus with the splinter of a broken bamboo sword. Imaging examinations did not show a brain injury or orbital bone fracture...

BACKGROUND: Recently, we have experienced a student who died of idiopathic ventricular fibrillation in a school where automated external defibrillator (AED) had been installed. The tragedy could not be prevented because the only AED in the school was installed in teachers' office situated far from the school ground where the accident took place. This occurrence prompted us to establish multiple AED system in schools. OBJECTIVE: We analyzed the effect of multiple AED system to prevent the sudden death of school aged children...

Decreases in saliva secretion compromise food mastication and swallowing, reduce mucosal immune function, and increase the risk for oral diseases like dental caries. Chlorella is a green alga that contains a variety of nutrients including amino acids, vitamins, and minerals. In our previous study, Chlorella-derived multicomponent supplementation did not affect salivary flow rates in healthy young individuals, but Chlorella-derived supplementation attenuated a decrease in saliva secretion that was observed during a kendo training camp...

Anomalous origin of the coronary artery (AOCA) is a rare, but important cause of sudden cardiac death among young athletes. Nine autopsy cases (8 male, 1 female; mean age, 17.9 years; age range, 11-31 years) of sudden death during or just after exercise caused by AOCA were reviewed. The exercises performed at the time of death were running (4 cases), soccer (2 cases), and baseball, swimming and kendo (Japanese swordsmanship) (1 case each). In 6 cases, the left coronary artery arose from the right sinus of Valsalva, and in 3, the right coronary artery from the left sinus...

Annular pulley injury of fingers is usually observed in rock climbers who support their entire body weight with flexed fingers during climbing. But these lesions can also follow trivial trauma, such as lifting heavy objects with the fingertips, or during sports and recreational activities. The A2 and A4 pulleys are most usually involved and reported most frequently. However, traumatic A1 pulley rupture has not been reported yet, to the best of our knowledge. Kendo is a very vigorous martial art with frequent physical contact...

One distinctive trait of kendo, the Japanese martial art of fencing, is the execution of sustained, high-effort vocalizations during actions. The purpose of this study was to determine the effect of these vocalizations on respiratory functions. First, the intensity of 3 kendo exercises was quantified by measuring oxygen uptake (V̇O2) and comparing it with V̇O2max measured during treadmill tests of 8 university kendo athletes. Respiratory variables of these 8 athletes were then analyzed using a portable breath gas analyzer during the most intensive kendo exercise, kakari-keiko, with and without vocalization...

Natural killer cells play a key role in the immune control of viral infections. Killer immunoglobulin-like receptors (KIRs) regulate natural killer cell activation and inhibition through the recognition of their cognate HLA class I ligands. We assessed the predictive factors of a sustained virological response (SVR) in 200 Japanese patients with chronic genotype 1b hepatitis C who were treated with telaprevir (TVR), pegylated-interferon-α2b (PEG-IFN), and ribavirin (RBV) triple therapy (92 patients) or PEG-IFN/RBV therapy alone (108 patients)...

The psychological stress of competition is a powerful stimulus affecting numerous hormones, which in turn change how pain is perceived. This study investigated whether a kumdo (kendo) team competition may be related to changes in hormones and pain. Seventeen healthy male kumdo practitioners participated in this experiment. Pain experiments were conducted by applying noxious stimuli with a thermal stimulator 10 min before a kumdo competition and 30 min post-competition. Serum testosterone, cortisol, beta-endorphin levels, pain thresholds, pain ratings at 48 °C and during blood sampling (sampling pain), anxiety, blood pressure, and heart rate were measured pre- and post-competition...

In many competitive sports, players need to quickly and continuously execute movements that co-adapt to various movements executed by their opponents and physical objects. In a martial art such as kendo, players must be able to skillfully change interpersonal distance in order to win. However, very little information about the task and expertise properties of the maneuvers affecting interpersonal distance is available. This study investigated behavioral dynamics underlying opponent tasks by analyzing changes in interpersonal distance made by expert players in kendo matches...

Between 1992 and 2010, we studied audiometric findings obtained from the annual hearing examination for senior high-school students who belonged to an active Kendo team. The subjects comprised 140 males and 88 females with ages between 15 and 18 years. The pure tone audiometry showed that 69 ears of 45 students (19.7%) had sensorineural hearing loss with the highest threshold shift at 2000 Hz, followed by 4000 Hz. Frequent audiometric patterns included a 2000 Hz-dip, a 4000 Hz-dip and a combined loss of 2000 and 4000 Hz...
