INTRODUCTION: Sleep has numerous important physiological and cognitive functions that may be particularly important to elite athletes. Sleep deprivation can have significant effects on athletic performance. However, there are few published data related to the amount of sleep obtained by elite athletes. We investigated sleep patterns of Korean women golfers using sleep-related questionnaires. METHODS: For this study, 98 Korean university women golfers and 46 age- and sex-matched controls were recruited. All subjects were asked to complete the self-administered sleep questionnaire consisting of questions about habitual sleep patterns (sleep onset time, sleep latency, awakening time in the morning, day time napping time), exercise habits, Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISS), Pittsburgh Sleep Quality Index (PSQI), validation of the Perceived Stress Scale (PSS), and Beck Anxiety Inventory (BAI). RESULTS: The sleep onset time was significantly earlier (pm 23 : 05 +/- 00 : 52 and 00 : 14 +/- 00 : 51 ; t = 5.287, p < 0.001), the waking time was later (am 07 : 21 +/- 01 : 09 and 6 : 35 +/- 00 : 32; t = -2.715, p = 0.008), the weekday total sleep time was greater (417.77 +/- 78.18 minute and 351.52 +/- 77.83 minute ; t = 4.406, p = 0.001), and the daytime nap time was greater (77.73 +/- 41.28 minute and 20.22 +/- 33.03 minute ; t = 7.623, p < 0.001) in the golf athletes compared to the controls. The PSQI scores were significantly lower, but estimated sleep latency and ESS, ISS, PSS, and BAI scores were not different among the two groups. CONCLUSION: This study suggests that Korean university women golfers have good sleep patterns resulting in no difference in sleep-related stress compared to age- and sex-matched control students.

Purpose: Divergence insufficiency is characterized by esotropia at far distance with symptomatic diplopia, minimal or no deviation at near distance, and full ocular duction and version. We analyzed the results of bilateral lateral rectus (BLR) tucking in patients with divergence insufficiency. Methods: Surgery was performed on patients with persistent distance diplopia with esotropia for at least 6 months after diplopia onset. The surgical results were evaluated after BLR tucking based on the maximum angle of deviation at distance among all the angles of deviation measured repeatedly, including the results of the prism adaptation test (PAT). Results: 24 patients were included. The average follow-up period was 14 months (1-48 months). The maximum deviations measured by alternate prism and cover test before surgery were 24.79 ± 8.15 prism diopter (PD) at far distance and 15.45 ± 9.30 PD at near distance. The PAT revealed that, the far distance deviation increased to 28.50 ± 7.77 PD and that at near distance to 25.88 ± 8.07 PD, but the difference between the two values fell to less than 3 PD on average. In 14 patients (58%), followed-up for up to 1 year, we noted no recurrence of diplopia or esotropia, or near distance overcorrection, with the exception of one patient who developed diplopia recurrence at far distance. Conclusions BLR tucking guided by the maximum distance deviation of the 1 hour PAT affords stable results in patients with divergence insufficiency without overcorrection at near distance or undercorrection at far distance.

Isolated situs in versus of the stomach with otherwise normal position of the thoracic and abdominal vescera isan extremely rare anomaly occurring in two distinct forms. Majority of cases are associated with eventration of the diaphragm and are reported as being confused with spontaneous pneumothorax of pyopneumothorax at base of the right lung. The right sided stomach may produce interesting and confusing changes in liver scan. We have experienced 2 cases of the isolated dextrogastria.

PURPOSE: To examine the cardiac function, incidence and natural history of cardiac hypertrophy (CH) and the association of side effects with CH after pulse dexamethasone therapy in infants with bronchopulmonary dysplasia. METHODS: Twelve infants, gestational age 28.6+/-1.6(26-31)weeks, birth weight 1243+/-186 (1010- 1620)g, received a pulse course of dexamethasone, starting at 0.5mg/kg/d for three days and readministered ten days thereafter at a median of 19 days of age. Serial echocardiographic measurement of septal thickness(ST), left ventricular(LV) posterior wall thickness(PWT), LV diameter(LVD), LV length(LVL), LV mass, ejection fraction(EF) and acceleration time to right ventricular ejection time ratio(AT/RVET) were taken before, and 4, 11 days after starting dexamethasone. For infants diagnosed as CH, echocardiography was performed weekly until the parameters were normalized. Side effects of dexamethasone such as leukocytosis, hypertension, hyperglycemia and insulin therapy were recorded and compared. RESULTS: CH occurred in 5 of 12 infants(47%). ST, PWD, and AT/RVET increased significantly at 4 days and 11 days after starting dexamethasone than baseline. LVD decreased significantly at 4 days and 11 days after the administration of dexamethasone than before. Other parameter such as LVL, LV mass and EF were not changed and the evidence of left ventricular outflow obstruction was not observed. The incidence of hyperglycemia and insulin therapy were higher in CH group than in no CH group(p<0.05). Five infants with CH recovered until five weeks after starting dexamethasone on serial echocardiography, CONCLUSION: Infants receiving a pulse course of dexamethasone developed evidence of septal hypertrophy, thickened left ventricular wall and impaired filling of left ventricle immediately after starting dexamethasone but always resolved within five weeks Serial echocardiography is not probably routinely required in preterm infants with bronchopulmonary dysplasia receiving pulse dexamethasone therapy.

Supracondylar fracture of the humerus is the most common fracture about the elbow in children and much has been written about its treatment and the prevention of both Volkmann's ischemia with contracture and the nerve injuries associated with these fractures. However, it is still one of the most difficult fractures to manage and is frequently associated with significant residual complications. Among these complications, the change in carrying angle is the most common one. In a retrospective survey of 102 children with supracondylar fractures of the humerus treated at the Department of Orthopedic Surgery of Kyungpook National University Hospital, 68 cases were found to have sufficient clinical and roentgenographic data to classify the fractures and to determine the carrying angles at end result. The results are as follows: 1. The mean age of the 102 patients at the time of fracture was 7.3 years (range, 2 to 17 years), and the fractures were on the left side in 67.6%, and male comprised 70.1%. 2, Of all fractures, 98% were the extension type, and the most common direction of initial displacement of the distal fragment was postero-medial. 3. According to Arnold et al classification, fractures with moderate varus or valgus displacement were the most common types in our series. 4. In the associated injuries with fractures, there were 5 nerve palsies and 5 fractures at the other sites. 5. In our series, the carrying angle of the opposite side of the fractured elbow ranged from 2 to 23 degrees of valgus angulation, with a mean of 9.2 degrees. 6. The decrease in carrying angle was most common in fractures with postero-medial displacement. 7, As far as the position of immobilization after reduction of the fracture is concerned, there was less tendency of decreasing the carrying angle in pronated group. 8. Most cases were treated by conservative method. There was no significant difference in change of carrying angle between the cases treated by closed reduction and those by skeletal traction.
