Effects of a dietary supplement of carp gallbladder powders, New-Eyereturn^®, on visual functions were investigated in elder ophthalmic patients. The tablets (12 tablets/day) were taken by 15 and 12 subjects for one-month and three-month period, respectively. In comparison with the visual function data at baseline and thereafter, improvements of subjective symptoms by questionnaire was observed in a three-month intake group, although no significant difference of the values of visual acuity and intraocular pressure was recognized. These results suggest intake of this dietary supplement has a possibility to improve visual functions of elder people.

Physicians expect nurses to be able to understand electrocardiographic (ECG) findings.However, many nurses have difficulty learning how to interpret ECGs.We suspect that the reason for such difficulty might be the nurses'mental responses to ECGs, rather than improper teaching methods.
1) We performed a questionnaire survey to investigate the mental responses to ECGs based on the responses of 197 experienced nurses and 43 new nurses and on an additional survey of 37 nurses who took ECG evaluation tests.
2) Almost all nurses recognized the necessity and importance of understanding ECG findings, and most wished to master ECGs.On the other hand, many nurses said that they disliked ECGs and did not feel competent interpreting ECGs.In particular, their perceived lack of competence in interpreting ECGs was greater than their dislike of ECGs.
3) The nurses'perceived lack of competence interpreting ECGs tended to result from feelings that developed during nursing school.Many nurses continued to have such feelings even after they began working.
4) Nurses with a poor understanding of ECGs reported many factors as being associated with their perceived lack of competence.In addition, such negative feelings toward ECGs (such as fear of making a mistake) made these nurses avoid ECGs.We believe that these feelings were likely a factor in why many nurses had difficulty mastering ECGs.
5) Nurses should be provided with appropriate ECG training that carefully considers the perceived incompetence and fear of many nurses regarding ECGs.

STUDY DESIGN: Retrospective case-control study. PURPOSE: To determine whether kissing spine is a risk factor for recurrence of sciatica after lumbar posterior decompression using a spinous process floating approach. OVERVIEW OF LITERATURE: Kissing spine is defined by apposition and sclerotic change of the facing spinous processes as shown in X-ray images, and is often accompanied by marked disc degeneration and decrement of disc height. If kissing spine significantly contributes to weight bearing and the stability of the lumbar spine, trauma to the spinous process might induce a breakdown of lumbar spine stability after posterior decompression surgery in cases of kissing spine. METHODS: The present study included 161 patients who had undergone posterior decompression surgery for lumbar canal stenosis using a spinous process floating approaches. We defined recurrence of sciatica as that resolved after initial surgery and then recurred. Kissing spine was defined as sclerotic change and the apposition of the spinous process in a plain radiogram. Preoperative foraminal stenosis was determined by the decrease of perineural fat intensity detected by parasagittal T1-weighted magnetic resonance imaging. Preoperative percentage slip, segmental range of motion, and segmental scoliosis were analyzed in preoperative radiographs. Univariate analysis followed by stepwise logistic regression analysis determined factors independently associated with recurrence of sciatica. RESULTS: Stepwise logistic regression revealed kissing spine (p=0.024; odds ratio, 3.80) and foraminal stenosis (p<0.01; odds ratio, 17.89) as independent risk factors for the recurrence of sciatica after posterior lumbar spinal decompression with spinous process floating procedures for lumbar spinal canal stenosis. CONCLUSIONS: When a patient shows kissing spine and concomitant subclinical foraminal stenosis at the affected level, we should sufficiently discuss the selection of an appropriate surgical procedure.
