Coffee Consumption and Bone Mineral Density in Korean Premenopausal Women / 가정의학회지

BACKGROUND: Although Asian people are known to have lower bone mass than that of Caucasians, little is known about coffee-associated bone health in Asian. This study aimed to assess the relationship between coffee consumption and bone mineral density (BMD) in Korean premenopausal women. METHODS: Data were obtained from the Fourth Korea National Health and Nutrition Examination Survey 2008-2009. The study population consisted of 1,761 Korean premenopausal women (mean age 36 years) who were measured for lumbar spine and femoral neck BMD and who completed a standardized questionnaire about coffee intake frequency. We excluded the participants who took hormone replacement therapy or medication for osteoporosis. The cross-sectional relationship between coffee consumption and impaired bone health (osteopenia or osteoporosis) was investigated by bone densitometry. RESULTS: Coffee consumption showed no significant association with BMD of either femoral neck or lumbar spine, independent of other factors. The adjusted odds ratios for BMD for those who consumed once in a day, twice a day and three times a day were 0.94 (0.70-1.26), 0.93 (0.67-1.28), and 1.02 (0.69-1.50), respectively (P for trend = 0.927). CONCLUSION: This study does not support the idea that coffee is a risk factor for impaired bone health in Korean premenopausal women.

Botulinum Toxin Treatment on Upper Limb Function in School Age Children With Bilateral Spastic Cerebral Palsy: One Year Follow-up

OBJECTIVE: To prospectively investigate the long-term effects of botulinum toxin treatment on the upper limb function and performance of school age children with spastic bilateral cerebral palsy, who have limitations in performing activities of daily living and school activities, due to spasticity of the upper extremities. METHODS: Botulinum type A toxin (BoNT-A) was injected into 24 spastic upper limbs of 15 children. We used a Modified Ashworth Scale and a Modified Tardieu Scale for the evaluation of upper limb spasticity, and Quality of Upper Extremity Skills Test (QUEST), Canadian Occupational Performance Measure (COPM), and Test of Visual-Motor Skills-Revised (TVMS-R) for the evaluation of upper limb function and performance. RESULTS: Upper limb spasticity continuously decreased until the end of the one-year follow-up. Upper limb function on QUEST and COPM showed the best performance at 3 months and deteriorated slightly, but still showed a significantly better performance at 9 and 12 months than at pre-injection. In more functional nine subjects who could perform TVMS-R, the performance enhancement effects remained constant after 12 months, suggesting that the reduced spasticity led to the learning effect acquired by the repeated use of the affected upper limb. CONCLUSION: For school age children with bilateral spastic cerebral palsy whose upper limb functions are important, BoNT-A injections seem to be of help in the performance of school activities and activities of daily living.

Deformities of Spine and Lower Extremities in Teenagers with Cerebral Palsy

OBJECTIVE: To investigate the state of musculoskeletal deformities in spine and lower extremities in teenagers with cerebral palsy. METHOD: 79 teenagers with cerebral palsy attending special schools were examined for deformities of the spine and the lower extremities with physical examinations and radiographic studies. RESULTS: The number of cases with scoliosis was 47 (59.5%) and the mean of Cobb's angle was 21.7 degrees. There were 42 joints (26.6%) of hip subluxation and 10 joints (6.3%) of hip dislocation out of 158 hip joints. The mean of migration percentage was 53.6%. 30 participants (38.0%) had pelvic obliquity. The coxa valga appeared in 147 hip joints (93.0%), with the mean of femur neck-shaft angle was 156.0 degrees. It had a casual link with migration percentage (p<0.001). 131 knee joints (82.9%) had the increased popliteal angle and 113 knees (71.5%) had patella alta. 72 cases (91.1%) had equinus feet, and 49 cases (62.0%) had planovalgus feet deformities on radiographic studies. As the score of Gross motor function measure (GMFM) was decreased, the migration percentage (p<0.01), the Cobb's angle (p<0.01), the popliteal angle increased (p<0.001) and femur neck- shaft angle (p<0.05). CONCLUSION: Teenagers with cerebral palsy are highly risk to develop musculoskeletal deformities in their spine and the lower extremities. Therefore, a close medical inspection should be paid on this group.

Prevalence of Nutrition Labeling and Claims on Processed, and Packaged Foods / 대한지역사회영양학회지

This study investigated the prevalence of nutrition labeling and claims on processed and packaged foods. The final database consists of 1,287 foods, which were collected in two supermarkets in the Seoul area from September to November, 2006. An estimated 78% of KFDA-regulated processed, and packaged foods have nutrition labels. Nutrient content claims on food labels were identified in 21% of the foods which have nutrition labels. The prevalence of nutrition labels in this study is much higher than in previous studies due to the current expansion of the mandatory labeling regulation. However, false labeling and misleading contents claims were also identified. The food label is an important tool for enhancing the public's understanding of healthy choices of processed foods. Therefore, to maximize the benefits of the nutrition labeling regulation, industries, government agencies and health professionals should work together to help consumers make healthy dietary choices and improve their health.

The Effects of Single Event Multi-level Chemoneurolysis on Upper Extremity Function in Children with Cerebral Palsy

OBJECTIVE: To investigate the effects of single event multi-level chemoneurolysis (SEMLC) on the upper extremity function along with the improvement of spasticity in children with cerebral palsy. METHOD: SEMLC using botulinum toxin and 5% phenol solution was done for the upper extremities of 22 children with spastic cerebral palsy. In control group, 17 children with spastic cerebral palsy were enrolled. The assessment of spasticity (modified Ashworth scale) and upper extremity function (quality of upper extremity skills test, QUEST) before and 4 weeks after treatment were examined. RESULTS: The spasticity of upper extremity was significantly reduced in SEMLC group compared with control group (p<0.05). The improvement of upper extremity function was significantly greater in SEMLC group than in control group (p<0.05). Children with spastic triplegia showed the largest change of QUEST compared with other types, but it wasn't statistically significant. In SEMLC group, initial QUEST score and the degree of improvement of QUEST after treatment showed significant negative correlation (p<0.05). CONCLUSION: This study revealed SEMLC of the upper extremity in cerebral palsy was the effective treatment which could improve the upper extremity function as well as reduce the spasticity itself.

Early rehabilitation program in postmastectomy patients: a prospective clinical trial

The purpose of this study was to determine whether 20 patients who received an early postmastectomy rehabilitation treatment program showed more improvement in range of shoulder motion and functional activities than 13 patients who received instruction for exercise only. Data were obtained at preoperatively, three days after operation, at discharge and at postdischarge one month for each patient on parameters such as range of motion of the ipsilateral shoulder joint, upper extremity circumferential measurements, as well as 10 elements of shoulder function. Postoperatively, both groups showed an increased range of motion of the shoulder joint and improved functional activities, but the group that received postoperative rehabilitation management had a better range of shoulder motion and less difficulty in five items for functional assessment. This study also showed that an early rehabilitation program did not increase postoperative complications. We concluded that an early rehabilitation program or intensive instruction program only by a well-trained physical therapist or physiatrist was beneficial to postmastectomy patients in regaining the function and range of shoulder motion, and significantly better in a rehabilitation group.
