A follow up study was made on patients who were admitted into our hospital because of stroke or fracture of the neck of the thighbone before and after the Nursing Care Insurance Law was enforced. The study found that there was a salient tendency for the number of days the patients stayed in hospital to increase and for the rate of discharge from hospital to the patients home to decrease.
As the nursing care insurance system came to stay, one local government after another was pulling out the functional training work which had been conducted as one from of the rehabilitation projects. In place of municipalities, nursing care service contractors were taking on such health service work as home visits for rehabilitation, and outside visits for nursing and rehabilitation. In the future, it would be necessary to establish a network enouth to promote health and welfare services including the provision of medical and rehabilitation equipment and the repair of houses.

PURPOSE: The present study aimed to investigate the relationships between the crown form of the upper central incisor and their labial inclination, overbite, and overjet. MATERIALS AND METHODS: Maxillary and mandibular casts of 169 healthy dentitions were subjected to 3D dental scanning, and analyzed using CAD software. The crown forms were divided into tapered, square, and ovoid based on the mesiodistal dimensions at 20% of the crown height to that at 40%. The degree of labial inclination of the upper central incisor was defined as the angle between the occlusal plane and the line connecting the incisal edge and tooth cervix. The incisal edges of the right upper and lower central incisor that in contact with lines parallel to the occlusal plane were used to determine the overbite and overjet. One-way ANOVA was performed to compare the labial inclination, overbite, and overjet among the crown forms. RESULTS: The crown forms were classified into three types; crown forms with a 20%/40% dimension ratio of 1.00±0.01 were defined as square, >1.01 as tapered, and <0.99 as ovoid. The labial inclination degree was the greatest in tapered and the least in square. Both overbite and overjet in tapered and ovoid were higher than those in square. CONCLUSION Upper central incisor crown forms were related to their labial inclination, overbite, and overjet. It was suggested that the labial inclination, overbite, and overjet should be taken into consideration for the prosthetic treatment or restoring the front teeth crowns.

INTRODUCTIONThis study aims to compare the long-term efficacy of 25-gauge vitrectomy to that of intravitreal bevacizumab (IVB) for the treatment of macular edema (ME) secondary to branch retinal vein occlusion (BRVO).

MATERIALS AND METHODSThe medical records of 46 eyes of 46 consecutive patients were reviewed. Twenty-seven eyes underwent 25-gauge vitrectomy (VIT Group) and 19 eyes received 1.25 mg of IVB (IVB Group). The best-corrected visual acuities (BCVAs) in logarithm of minimum angle resolution units and central macular thicknesses (CMTs) were evaluated before and 3, 6, and 12 months after the initial treatment.

RESULTSThere was no significant difference in the pre-treatment BCVA and CMT between the 2 groups. In the VIT Group, the preoperative BCVA was 0.59 and the CMT was 587.3 μm and the BCVA was 0.35 and the CMT was 286.6 μm, 12 months after the vitrectomy. Both values were significantly (P <0.05) better at 12 months than the preoperative values. In the IVB Group, the average number of IVB was 2.4 during the 1-year period. The BCVA was 0.69 and the CMT was 590.9 μm before the IVB, and the BCVA was 0.36 and the CMT was 360.1 μm, 12 months after the initial IVB. The improvements of these 2 parameters were significant (P <0.05) at 12 months after the initial IVB. The differences in the BCVA and CMT at 12 months between the 2 groups were not significant.

CONCLUSIONThese results suggest that the 25-gauge vitrectomy and IVB have similar effects in improving the BCVA and CMT in eyes with ME secondary to BRVO. However, IVB often required several injections to preserve the improvement.

Farmer's lung is a form of hypersensitivity pneumonitis, which is manifested mainly as an occupational disease among dairy farmers exposed to organic dusts from moldy hay and compost in silos and lofts. In Europe and America, it has been known for many years. In Japan, it frequently occurs in Hokkaido, Iwate and Hokuriku districts during winter months from November to March. The culprit antigens are spores of actinomycetes thermophilus such as Micropolyspora faeni and Thermoactinomyces vulgaris. In recent years, various preventive measures have been taken. For instance, in order to prevent hay from heating by fermentation and the thermophile from thriving, farmers desiccate hay as much as possible and keep it in air-tight plastic containers. The result is a notable decrease in the prevalence rate of this ailment. Nonetheless, with graying the rural population, pulmonary fibrosis caused by chronic exposure to low levels of organic dust is posing a grave health problem in the dairy farming communities. As a prophylactic measure against chronic fibrotic lung disease, there is a need to implement a comprehensive heath control program consisting of continual sanitary checkups at workplace and counseling at an early stage in addition to periodic health examinations. Another health threat which has more recently loomed up in the dairy farming communities is environmental pollution.
