PURPOSE: The purpose of this study was to compare the grade of fatty degeneration and atrophy of rotator cuffs on immediate postoperative MRI to those on preoperative MRI in patients with rotator cuff tears. MATERIALS AND METHODS: Seventy patients were included in this study, who received arthroscopic rotator-cuff repair and underwent both preoperative magnetic resonance imaging (MRI) and immediate postoperative MRI in our institution. Fatty degeneration of rotator cuffs and the atrophy of supraspinatus muscles were evaluated with T1 oblique sagittal images in the Y-shaped view. Fatty degeneration was evaluated using a Goutallier classification system, and the atrophy of supraspinatus muscles was evaluated using a modified tangent sign and a visual occupation ratio. RESULTS: From 70 patients, a total of 100 tendons were repaired: 18, 69, and 13 tendons were treated for subscapularis, supraspinatus, and infraspinatus, respectively. The Goutallier grades (P = 0.012), modified tangent signs (P = 0.000), and visual occupation ratios (P = 0.000) of supraspinatus muscles were significantly decreased in immediate postoperative MRIs when compared to preoperative MRIs. In immediate postoperative MRIs, the Goutallier grades of supraspinatus muscles were decreased by one grade in 18.8% (n = 13) of the patients, and the atrophy of supraspinatus muscles was improved by one grade in 26.1% (n = 18) for modified tangent signs and 21.7% (n = 15) for visual occupation ratios. However, fatty infiltration by the Goutallier grades of subscapularis (P = 1.000) and infraspinatus (P = 0.157) muscles were not significantly changed after arthroscopic surgery. CONCLUSION: Immediate postoperative MRIs showed a significant improvement of fatty degeneration and muscle atrophy in supraspinatus muscles when compared to preoperative MRIs.

OBJECTIVE: To obtain normal data of quantitative sensory test (QST) in Korean adult. METHOD: The subjects were 85 normal adults aging from 30 to 69 years old, who had no abnormal sensory and neurologic problem. We performed following three QSTs on dominant side and one verbal questionnaire. 1) Semmes-Weinstein monofilament wire system (0.05 G, 0.2 G, 2 G, 4 G, 10 G, 300 G) for touch sensation, 2) Rydel-Seiffer Tuning Fork for vibration sensation, 3) TSA-2001 Thermal sensory analyser for thermal sensation, 4)University of Texas Subjective Peripheral Neuropathy verbal questionnaire. RESULTS: 1) Touch perception score measured with Semmes-Weinstein monofilament wire system, declined with age (p<0.01). 2) Vibration perception score measured with the tuning fork, declined with age in foot (p<0.01). 3) Warm sense and heat pain threshold measured with TSA-2001 thermal sensory analyser increased with age, and cold sense and cold pain threshold declined with age. 4) Weight showed negative correlation with vibration perception score in man's foot. CONCLUSION: Normal data of three sensory test obtained from this study could be used for the early detection of peripheral neuropathy or loss of "protective sensation".

The study purpose was to investigate correlations among dietary habits score, life stress score and health-related quality of life (HRQL) score for female college students with functional constipation (FC). The data were collected in 2008 from 265 female college students: 86 with FC and 179 without FC. The diagnosis of FC was based on the Rome II criteria, and life stress and HRQL were assessed using self-administered life stress questionnaire and SF-36, respectively. The correlations among dietary habit score, life stress score, and HRQL score were evaluated. The averages of age, height, weight, body fat percentage and body mass index (BMI) of female college students were 20.8 years, 160.9 cm, 53.7 kg, 27.8%, and 20.7 kg/m2, respectively. The average dietary habit score of "having meals with diverse foods" was significantly lower in the FC group than in the normal group (p < 0.05). The average faculty problem (p < 0.05), grade problem (p < 0.05), economy problem (p < 0.05), value problem (p < 0.05), and total stress (p < 0.01) scores of the FC group were significantly higher than those of the normal group. The average HRQL score was 70.4 in the FC group and 74.3 in the normal group (p < 0.05). There were significantly negative correlations between total stress score and total food habits score (r = -0.221; p < 0.01) and HRQL score (r = -0.539; p < 0.01) in the FC. These results suggest that female students with FC are highly perceptive to stress and have low HRQL. In addition, female students with FC may require nutritional education about eating diversity.

This study aimed to determine whether taurine supplementation improves metabolic disturbances and diabetic complications in an animal model for type 2 diabetes. We investigated whether taurine has therapeutic effects on glucose metabolism, lipid metabolism, and diabetic complications in Otsuka Long-Evans Tokushima fatty (OLETF) rats with long-term duration of diabetes. Fourteen 50-week-old OLETF rats with chronic diabetes were fed a diet supplemented with taurine (2%) or a non-supplemented control diet for 12 weeks. Taurine reduced blood glucose levels over 12 weeks, and improved OGTT outcomes at 6 weeks after taurine supplementation, in OLETF rats. Taurine significantly reduced insulin resistance but did not improve beta-cell function or islet mass. After 12 weeks, taurine significantly decreased serum levels of lipids such as triglyceride, cholesterol, high density lipoprotein cholesterol, and low density lipoprotein cholesterol. Taurine significantly reduced serum leptin, but not adiponectin levels. However, taurine had no therapeutic effect on damaged tissues. Taurine ameliorated hyperglycemia and dyslipidemia, at least in part, by improving insulin sensitivity and leptin modulation in OLETF rats with long-term diabetes. Additional study is needed to investigate whether taurine has the same beneficial effects in human diabetic patients.

PURPOSE: To develop staffing levels for nursing personnel (registered nurses and nursing assistants) to provide inpatients with integrated nursing care that includes, in addition to professional nursing care, personal care previously provided by patients' families or private caregivers. METHODS: A time & motion study was conducted to observe nursing care activities and the time spent by nursing personnel, families, and private caregivers in 10 medical-surgical units. The Korean Patient Classification System-1 (KPCS-1) was used for the nurse manager survey conducted to measure staffing levels and patient needs for nursing care. RESULTS: Current nurse to patient ratios from the time-motion study and the survey study were 1:10 and 1:11, respectively. Time spent in direct patient care by nursing personnel and family/private caregivers was 51 and 130 minutes per day, respectively. Direct nursing care hours correlated with KPCS-1 scores. Nursing personnel to patient ratio required to provide integrated inpatient care ranged from 1:3.9 to 1:6.1 in tertiary hospitals and from 1:4.4 to 1:6.0 in general hospitals. The functional nursing care delivery system had been implemented in 38.5% of the nursing units. CONCLUSION: Findings indicate that appropriate nurse staffing and efficient nursing care delivery systems are required to provide integrated inpatient nursing care.

BACKGROUND: Angiogenesis is crucial for wound healing and exogenous supplements of the angiogenic growth factors have been known to promote cutaneous wound healing. Angiopoietin (Ang) 1 is a recently discovered angiogenic factor and there have been few studies of its effect on cutaneous wound healing. OBJECTIVE: We examined the effect of Ang 1 on cutaneous wound healing. METHODS: Cartilage oligomeric matrix protein (COMP)-Ang 1 (Ade-COMP-Ang 1)- was intravenously injected to rats two days before surgery creating full-thickness wounds. The clinical wound healing rate and the number of vessels in the skin samples were evaluated on days 3, 7 and 14 post operation. RESULTS: At post-operation day 3, 7 and 14, the clinical wound healing rate was 38.3%, 59.4% and 92.1%, respectively, in the Ade-COMP-Ang 1-treated group, compared with 20.5%, 47.5% and 87.3%, respectively, in the Ade-LacZ-treated group. There were significant differences in the results of day 3 and day 7 between two groups (p<0.05). Histopathologically, the number of the vessels of the Ade-COMP-Ang 1-treated group was 73.7, 94.1 and 62.7 at day 3, 7 and 14, compared with that of the Ade-LacZ-treated group, 53.5, 83.9, and 56.9. The differences in the results of the two groups were statistically significant (p<0.05). CONCLUSION: These results indicate that Ade-COMP-Ang 1 therapy significantly accelerats wound healing by promoting angiogenesis. However, further study using Ade-COMP-Ang 1 gene therapy for chronic wounds in which the formation of new blood vessels is impaired is needed in the near future.

PURPOSE: Iron deficiency anemia (IDA) is one of the most common nutritional problems, despite a recent improvement of nutritional status of infants and children. We assessed the risk factors for IDA in infants and vitamin D deficiency and IDA by nutrition analysis. METHODS: We analyzed blood tests and evaluated 103 children with IDA and 123 children without IDA, 6-36 months of age, who were cared for in our hospital between March 2006 and July 2010. Nutritional analysis using Canpro was performed among breastfed infants 6~12 months of age who had been diagnosed with IDA and had detailed diet histories. RESULTS: Breastfed infants accounted for 87.4% and 40.7% of the IDA and comparison groups, respectively. The IDA and comparison groups began weaning food at 6.4+/-1.8 and 5.9+/-1.3 months, respectively. In the IDA and comparison groups, 46.4% and 53.5% began to adapt to weaning food within 4 weeks, respectively. The most common reason for hospital care of the IDA group was respiratory symptoms constituting 36.2%. Only 18.6% visited the hospital for palloror anemia. The Canpro analysis, performed on 11 infants with IDA, showed that iron and vitamin D were <40% and 30% of recommended intakes, respectively. CONCLUSION: Weaning food should be started 4~6 months of age in breastfed infants. In infants at high risk for IDA and vitamin D deficiency, screening tests should be recommended. The high-risk infants may require iron, vitamin D fortified formula, or oral supplements.

BACKGROUND: Bisphosphonate is used in osteoporosis treatment to repress osteoclast activity, which then decreases levels of osteocalcin (OC). OC, a protein secreted by osteoblasts and released from the bone matrix during osteoclastic bone resorption, has been found to control blood glucose levels by increasing insulin production and sensitivity. The question addressed in this study is whether decreasing OC through bisphosphonate treatment will provoke a change in glucose homeostasis. METHODS: Eighty-four patients with osteoporosis were treated with once-weekly risedronate 35 mg and cholecalciferol 5,600 IU. We measured fasting plasma glucose (FPG), insulin, and undercarboxylated (Glu) and carboxylated (Gla) OC levels at baseline and after 16 weeks. To estimate insulin resistance (IR) and beta-cell function (B)%, homeostasis model assessment (HOMA)-IR and HOMA-B% were also calculated, respectively. RESULTS: The mean FPG level in total subjects increased significantly from 5.3 to 5.5 mmol/L, but no changes in blood glucose were noted in the 24 subjects with impaired fasting glucose. Glu and Gla OC levels declined significantly after treatment. No correlations were observed between changes in OC and changes in glucose, however. CONCLUSIONS: Bisphosphonate treatment for osteoporosis reduced OC, but this change was not associated with changes in glucose metabolism.
