Forearm bone mineral content for adult white elite synchronized swimmers is lower than that of normative data (Roby et al. 1988). However, bone mineral density (BMD) in local body regions and the body as a whole are unclear in adolescent synchronized swimmers. The purpose of this study was to examine BMD of adolescent synchronized swimmers. This study also examined the relationship between BMD for young athletes and biological (e. g. morphological and functional aspects) and habitual (e. g. physical activity and nutritional state in daily living) variables. Subjects were nine females selected nationwide out of a large number of synchronized swimmers of fourth to sixth grade in elementary school, who participated in an audition with the committee of synchronized swimming in the Japan Swimming Federation. Chronological and bone age were 13.4±1.0 years and 12.7±0.9 years (n=8), respectively. BMD was evaluated in local regions and the body as a whole by dual X-ray absorbtiometry (DXA). Walking was measured by pedometer, and physical activity and nutritional status were analyzed by activity diary and food weighing method, respectively. As a result, mean BMD in athletes tended to be lower than in normal Japanese girls for lower limbs and lumbar vertebra (L2-L4), while it was almost the same between the two groups for whole body, upper limbs, thoracic vertebrae and pelvis. The correlations between BMD for whole body and bone age, the number of years since menarche, body mass, lean body mass and physical activity in leisure time of daily life were significant. An analysis using a general linear model indicated that bone age and active leisure activity together explained 94.6% of the variance of the BMD. These findings indicate that BMD of adolescent synchronized swimmers tended to be unique in local regions. Furthermore, BMD in athletes was affected by the biological maturation level and physical activity in leisure time of daily life.

STUDY DESIGN: Historical controlled trial. PURPOSE: To clarify the usefulness of cryotherapy after spine surgery. OVERVIEW OF LITERATURE: Cryotherapy has generally been performed subsequent to surgery on joints and in this application its clinical effects are well understood. However, cryotherapy has yet to be used following spine surgery. Its clinical efficacy in this context is unknown. METHODS: Thirty six patients had undergone one level microendoscopic surgery. Sixteen were enrolled into the cooling group, with the remaining 20 making up the no postoperative cryotherapy control group. Cryotherapy was performed at 5degrees C using an icing system. A silicone balloon catheter with a thermo sensor on the tip was placed in the surgical wound. The temperature in the wound was recorded every 30 minutes until the next morning. The relationship between the depth of the sensor and the temperature in the wound were investigated using simple linear regression analysis. Laboratory data, visual analogue scale (VAS) for wound pain and postoperative bleeding were investigated. RESULTS: The mean temperature in the surgical wound was 37.0 in the control group and 35.0degrees C in the cooling group (p<0.001). There was a positive correlation between the depth of the thermo sensor and the temperature in the wound in the cooling group (y=0.91x+30.2, r=0.67, p=0.004). There were no significant differences between the groups in terms of laboratory data, VAS or postoperative bleeding. CONCLUSIONS: The temperature in the wound was decreased significantly by spinal surgery cryotherapy.

This study sought to evaluate how a training program on spiritual care affected physicians’ confidence, self-reported practice, and attitudes in caring for terminally ill cancer patients who express meaninglessness in living. Questionnaires were distributed to participating physicians before and after the training program. A total of 30 physicians completed the program. Confidence and self-reported practice regarding communication with terminally ill cancer patients who express meaninglessness significantly improved after the training: effect size, 1.3 (P=0.0001) and 1.2 (P=0.0001), respectively. Moreover, physician-reported helplessness significantly decreased (effect size, 0.8; P=0.0001) and positive appraisal and willingness to participate in caring for terminally ill cancer patients experiencing meaninglessness significantly improved (effect size, 0.8, P=0.0001; effect size, 0.4, P=0.0001, respectively). Overall, 96–100% of the participating physicians reported the program was useful for understanding the concept of spiritual care and for learning a practical approach for caring for such patients.
