Background No large-scale study of the timing of autism spectrum disorder (ASD) diagnosis has been performed in Japan to date. The aim of this study was to examine sex differences and annual trends in age at diagnosis of ASD using clinical data. Methods Clinical data for children aged less than 18 years diagnosed with ASD between January 1, 2009, and December 31, 2013, and in whom follow-up was possible 1 year after diagnosis, were extracted. Results The mean age at ASD diagnosis was 7.2 ± 4.2 years and the mode age was 3 years. No sex difference was observed for age at diagnosis (p = 0.157). An annual trend of earlier diagnosis was observed when fiscal years were compared (p < 0.001). Conclusion This study highlighted the need to develop and provide appropriate early intervention methods and services for ASD children in Japan.

Objectives The purpose of this study was to determine the factors related to changes in the burden of caregivers who look after the elderly at home, as well as factors related to the institutionalization of the elderly who require care. The types of care services associated with reducing caregivers' burden and continuing in-home care were also studied. Methods The study subjects were adults aged C65 years who used the services of in-home care management centres located in Osaka Prefecture, Japan, and their caregivers. This 2-year longitudinal study began in October 2007, with a total of three surveys undertaken once a year. The survey methods included self-administered questionnaires and the review of clinical records. Results Dementia and its accompanying behavioural disturbances were found to be significantly related to the increased burden of caregivers and the institutionalization of those requiring care. A significantly higher proportion of caregivers with an increasing burden or those who maintained a high level of burden used day care services compared to those in the other groups. Conclusion Preventive intervention against dementia and its accompanying behavioural disturbances should be considered in the day care service to reduce caregivers' burden and to decrease institutionalization.

The SSEs appeared effective for fall prevention and improvement of physical function in older adults. Implications for Rehabilitation The newly developed short stick exercises appear an effective means of reducing falls among older adults in residential care facilities. The short stick exercises seem to have an immediate effect on improving physical functions. Effects gained by performing the short stick exercises, such as static balance, flexibility and agility may last for six months. The short stick exercises were found to be easy for older adults to practice continuously in residential care facilities.

Clinical data in Japan were used to examine the age at diagnosis of autism spectrum disorders (ASD) in children in Japan. Results indicate that the mean age at diagnosis for 7779 participants was 7.3±4.3 years, the mode 3.0 years, and the median 6.0 years. The male-to-female ratio was 3:1. There were no sex differences in the age at diagnosis of any ASD. Asperger's syndrome was diagnosed at older ages than other disorders, but no clear peak was indicated for the age at diagnosis. Only childhood autism was diagnosed early in life and showed an annual trend. This study suggests the need to develop a system or tool that enables early diagnosis of Asperger's syndrome, as well as the need to develop a proper early intervention techniques and service provisions for childhood autism.

The aim of this study was to investigate the association between the morphologic classification of nailfold capillary microscopy and the clinical and demographic findings in workers exposed to hand-arm vibration. The subjects were 44 male forestry workers (average age; 51.9 ± 14.8 yr). The nailfold capillaries (NC) and the mean blood flow velocity were measured on the middle finger of the dominant side by a peripheral capillary observer. The analyses were made using 39 subjects after excluding five subjects who received medication for hypertension. The observed NC were classified into 5 types according to Kusumoto's classification: Type I, n=5; Type II, n=15; Type III, n=8; Type IV, n=5; and Type V, n=6. After excluding the subjects in the Type V, we divided the subjects into two groups: Type I/II group, n=20; and Type III/IV group, n=13. In the Type III/IV group, the operating year of handheld vibrating tools was relatively longer, the mean blood flow velocity was significantly slower, and the body mass index was relatively higher as compared to the Type I/II group. These results suggested that the nailfold capillary microscopy may reflect the effect of the vibration exposure.
