In patients with unilateral mandibular condyle hyperplasia, whether to perform condylectomy and orthognathic surgical procedures at the same time or orthognathic surgery in two stages for remains controversial. Reported here is a case of facial asymmetry with mandibular condyle hyperplasia, for which condylectomy and orthognathic surgery procedures were performed at the same time. A 28-year-old woman was presented to our department with chief complaints of left deviation of the mandible and right temporomandibular joint (TMJ) noise. Findings obtained in several imaging examinations led to a diagnosis of facial asymmetry associated with right mandibular condyle hyperplasia. Following 3 months of preoperative orthodontic treatment, in October 2018 under general anesthesia the patient underwent a right mandibular condylectomy, Le Fort I osteotomy, right mandibular sagittal split ramus osteotomy, and left mandibular inverted L ramus osteotomy. In examinations up to 3 years after surgery, good results were noted.For this case of severe facial asymmetry with mandibular condyle hyperplasia, early surgery and condylectomy were performed simultaneously to significantly shorten the total treatment time. The effectiveness of a surgery-early approach was confirmed by no postoperative findings indicating abnormalities in the TMJ or retroversion.

Endovascular treatment for wide-necked posterior communicating artery (PcomA) aneurysms with a fetal-type variant of the posterior cerebral artery (PCA) is often challenging. Since the complete occlusion rates achieved with the currently available treatment methods are unsatisfactory, we aimed to study the effectiveness of a double-balloon-assisted technique for these aneurysms. From September 2014 to August 2020, 6 consecutive patients with PcomA aneurysms with fetal-type PCAs and no previous treatment were treated with this technique at our institution (3 ruptured cases and 3 unruptured cases). The indication for this technique is that the neck of the aneurysm should significantly and broadly incorporate both the internal carotid artery and fetal-type PCA, such that a single-balloon remodeling and single stent would be inadequate to protect both the arteries. In all patients, the fetal-type PCAs were preserved without a stent and with adequate occlusion status. This double-balloon technique can be effective in the treatment of these aneurysms.

BACKGROUND:
Public perceptions and personal characteristics are heterogeneous between countries and subgroups, which may have different impacts on health-protective behaviors during the coronavirus disease 2019 (COVID-19) pandemic. To assess whether self-reported perceptions of COVID-19 and personal characteristics are associated with protective behaviors among general adults and to compare patterns in six different countries.
METHODS:
This cross-sectional study uses the secondary data collected through an online survey between 15 and 23 April 2020 across six countries (China, Italy, Japan, Korea, the UK, and the USA). A total of 5945 adults aged 18 years or older were eligible for our analysis. A logistic regression model was used to estimate odds ratios (OR) and 95% confidence intervals (95%CI) of three recommended behaviors (wearing a mask, handwashing, and avoiding social gatherings).
RESULTS:
In most countries except for China, the participants who perceived wearing a mask as being extremely effective to curtail the pandemic were more likely to wear a mask (OR, 95%CI: Italy: 4.14, 2.08-8.02; Japan: 3.59, 1.75-7.30; Korea: 7.89, 1.91-31.63: UK: 9.23, 5.14-17.31; USA: 4.81, 2.61-8.92). Those who perceived that handwashing was extremely effective had higher ORs of this preventive behavior (OR, 95%CI: Italy: 16.39, 3.56-70.18; Japan: 12.24, 4.03-37.35; Korea: 12.41, 2.02-76.39; UK: 18.04, 2.60-152.78; USA: 10.56, 2.21-44.32). The participants who perceived avoiding social gathering as being extremely effective to curtail the pandemic were more likely to take this type of preventive behavior (OR, 95%CI: China: 3.79, 1.28-10.23; Korea: 6.18, 1.77-20.60; UK: 4.45, 1.63-11.63; USA: 4.34, 1.84-9.95). The associations between personal characteristics, living environment, psychological status, and preventive behaviors varied across different countries. Individuals who changed their behavior because of recommendations from doctors/public health officials were more likely to take preventive behaviors in many countries.
CONCLUSIONS
These findings suggest that higher perceived effectiveness may be a common factor to encourage preventive behaviors in response to the COVID-19 pandemic. These results may provide a better understanding of the homogeneity and heterogeneity of factors related to preventive behaviors and improve public health policies in various countries and groups.

We aimed to clarify the significance of using Kampo therapy centered on kamishoyosan and tokishakuyakusan together with general infertility treatment. The subjects were 41 women who visited a Kampo outpatient clinic for infertility and received general infertility treatment with Kampo therapy (Kampo group). The control group was 781 women who received only general infertility treatment at the same time (non-Kampo group). In comparing both groups, we conducted a retrospective survey on the pregnancy rate by cycle and the pregnancy rate by prescription. The pregnancy rate in the first cycle was 24.4% in the Kampo group and 8.5% in the non-Kampo group, and the pregnancy rate was higher in the Kampo group (P = 0.003). There was no difference in pregnancy rates after the second cycle. The pregnancy rate by prescription was 26.7% for kamishoyosan, 22.2% for tokishakuyakusan, and 8.5% for the non-Kampo group. In the comparison between the first cycle pregnant group and the non-pregnant group, the qi counter flow score was clearly higher in the first cycle pregnant group (P = 0.012). It is suggested that combined use of Kampo therapy including kamishoyosan and tokishakuyakusan may be effective from an early stage. Meanwhile, if pregnancy does not occur even after the combined use of Kamp therapy, it would be an opportunity to consider stepping up as Western medical therapy.

In this study, observing football players under simulated playing conditions to measure event-related potentials (ERPs, i.e. P300), electromyography reaction time (EMG-RT), and reaction time (RT), we investigated neural correlates of information processing during selective reaction challenges. A high performance group included 13 collegiate football players who had previously won the All Japan University Championships. A low performance group included 13 collegiate football players who never competed at the national level or played in prefectural or regional competitions. We conducted a 4 vs. 2 ball possession task (i.e. a Go/NoGo task) under simulated playing conditions that required situational assessment. Our results showed that the high-performance group had a significantly higher correct response rate than did the low-performance group in 4 vs. 2 ball possession tasks. Moreover, the EMG-RT and RT of the high-performance group were significantly shorter than that of the low-performance group. Furthermore, the P100 and P300 latencies of the high-performance group was significantly shorter than those of the low-performance group. These findings indicated that high-performance football players could perform the task-relevant stages of information processing (such as visual information processing, stimulus evaluation, and motor response output) in a short time. There was no correlation between EMG-RT and P100 (Go, NoGo stimulation), indicating that initial visual information processing did not contribute to the execution of the final motor response. There was no correlation between EMG-RT and Go P300 latency, whereas a significant correlation with NoGo P300 latency was shown. This suggested that the stimulus evaluation system by NoGo stimuli (response inhibition) is strongly involved in the final motor output reaction.

A population-based cohort study on pediatric infectious diseases was established at Khanh Hoa Province, central Vietnam in 2006, to determine the etiology and risk factors for severe pediatric infectious diseases (SPID) such as acute respiratory infection (ARI), diarrhea and dengue which are the major causes of under 5 mortality. A population census survey was conducted in Nha-Trang and Ninh-Hoa to collect demographic, social-behavioral data and disease burden on SPID. The study site covered a population of 353,525 residing in 75,826 households with 24,781 children less than 5 years. Hospital databases from two hospitals covering the region were obtained. Linking the census and hospital databases, we were able to investigate on a variety of SPID such as environmental tobacco smoking exposure and increased risked of pediatric pneumonia hospitalization, population density, water supply and risk of dengue fever and animal livestock and risk of hospitalized diarrhea. To determine incidence, viral etiology and risk factors for pediatric ARI/pneumonia, we setup a population based prospective hospitalized Pediatric ARI surveillance at Khanh Hoa General Hospital, Nha-Trang in February 2007. The study has revealed RSV, rhinovirus and influenza A as major viral pathogens, role of multiple viral infection and its interaction with bacteria in the development of pneumonia. In addition, we are also conducting a birth cohort study to investigate the incidence of congenital infection and its impact on physical-neurological development, and role of host genetic polymorphism on SPID hospitalization in Vietnam. Population mobility, high cost of regular census update and low mortality are the challenges.

PURPOSE: Transient receptor potential vanilloid 1 (TRPV1) is a ligand-gated nonselective cation channel, which can be activated by capsaicin and other noxious stimuli. Recently, an association between bone pain and TRPV1 has been reported. However, the influence of osteoporosis on TRPV1 in the sensory system innervating the femur has not been reported. MATERIALS AND METHODS: TRPV1-immunoreactive (ir) in dorsal root ganglia (DRG) neurons labeled with neurotracer [Fluoro-Gold (FG)] innervating the femurs of Sprague Dawley rats were examined in control, sham, and ovariectomized (OVX) rats. We evaluated osteoporosis in the femurs and compared the proportion of TRPV1-ir DRG neurons innervating femur between the 3 groups of rats. RESULTS: OVX rats showed osteoporotic cancellous bone in the femur. FG labeled neurons were distributed from L1 to L6 DRG, but there was no significant difference in the proportion of labeled neurons between the 3 groups (p>0.05). The proportions of FG labeled TRPV1-ir DRG neurons were 1.7%, 1.7%, and 2.8% of DRG neurons innervating the femur, in control, sham-operated, and OVX rats, respectively. The proportion of TRPV1-ir neurons in DRG innervating the femur in OVX rats was significantly higher than that in control and sham-operated rats (p<0.05). CONCLUSION: Under physiological conditions, DRG neurons innervating femurs in rats contain TRPV1. Osteoporosis increases the numbers of TRPV1-ir neurons in DRG innervating osteoporotic femurs in rats. These findings suggest that TRPV1 may have a role in sensory perception of osteoporotic femurs.

PURPOSE: Pain from vertebral or femoral neck fractures is a particularly important problem in clinical orthopaedics. Transient receptor potential vanilloid 1 (TRPV1) is a ligand-gated nonselective cation channel, and there are recent reports on an association between bone pain and TRPV1. However, an increase in TRPV1 activity has not been reported following femoral fracture. MATERIALS AND METHODS: We applied a neurotracer [Fluoro-gold (FG)] onto femur to detect dorsal root ganglia (DRGs) innervating the cortex of the femur in 30 Sprague Dawley rats. Seven days after application, a closed mid-diaphyseal fracture of the femur was performed. FG labeled TRPV1-immunoreactive (ir) DRGs innervating the femur were examined in nonfractured controls, and 3 days, 1 week, 2 weeks, and 4 weeks after fracture. We evaluated bone healing of the femur and compared the ratio of TRPV1-ir DRG neurons innervating the femur at the time points. RESULTS: Four weeks after fracture, complete bone union was observed. There was no significant difference in the ratio of FG labeled DRG neurons to total DRG neurons at each time point. The percentages of TRPV1-ir neurons in DRGs innervating the femur at 3 days and 1 week after fracture were significantly higher than those in control, 2 weeks, and 4 weeks after fracture (p<0.05). CONCLUSION: Fracture induced an increase of TRPV1-ir neurons in DRGs innervating the fractured femur within 3 days, and decreased during bone healing over 4 weeks. These findings show that TRPV1 may play a role in sensory sensation of bone fracture pain.

OBJECTIVE: The aim of this study was to explore the factor structure of a novel, 10-item rating scale, the Targeted Inventory on Problems in Schizophrenia (TIP-Sz). Determining the factor structure will be useful in the brief evaluation of medication and non-medication treatment of the disease. METHODS: An exploratory factor analysis was performed on TIP-Sz scores obtained from 100 patients who met the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria for schizophrenia. RESULTS: The factor analysis extracted four factors that were deemed clinically pertinent, which we labeled: disorganization, social cooperativeness, functional capacity, and emotional state. The items exhibited cross-loadings on the first three factors (i.e., some items loaded on more than one factor). In particular, the 'behavioral dyscontrol and disorganization,' 'insight and reality testing,' and 'overall prognostic impression' items had comparable cross-loadings on all of the first three factors. The emotional state factor was distinct from the other factors in that the items loading on it did not cross-load on other factors. CONCLUSION: The TIP-Sz scale comprises factors that are associated with the psychosocial functioning and emotional state of patients, which are important outcome parameters for successful treatment of the disease.
