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.

The treatment of choice for Cushing's disease is surgical removal of tumor, the source of ACTH overproduction. In occasional patients in whom a surgical approach including total adrenalectomy is not feasible or surgical removal of tumor is not complete, medical treatment may be necessary because pituitary irradiation requires a long 1ag time to remission. Although ketoconazole, an imidazole derivative with inhibitory activity on adrenal steroidogenesis has been reported to be effective in the treatment of Cushing's disease, the limited effectiveness in lowering very high level of cortisol and occasional hepatotoxicity restrains its wide use. In this report, we describe a woman with Cushing's disease due to pituitary microadenoma. Transsphenoidal pituitary adenomeetomy followed by ketoconzole treatment had been unsuccessful in achieving remission of the disease, but combined treatment with ketoconazole and octreotide accomplished successful reduction in cortisol production.

Edentulous patients with a severely resorbed mandible or maxilla often experience problems with conventional dentures, such as insufficient stability and retention, together with a decrease in chewing ability. Because of the good prognosis of dental implants, these patients can be successfully treated with implant-retained or implant-supported prosthesis. Ideally, a maximum number of implants of maximum length are placed in appropriate surgically prepared sites that are surrounded by a maximum amount of bone of favorable quality. The implants are favorably aligned faciolingually and mesiodistally to enhance optimal prosthodontic design. This article describes the clinical problems and complications encountered when treating a consecutive number of edentulous patients with osseointegrated implant-supported prostheses.

STATEMENT OF PROBLEM: For a long time, many of denture base acrylic resins have been used for edentulous and partial edentulous patients because of easy manipulation and good mechanical properties, but its esthetic aspect has not been commented enough. Denture base acrylic resins also has caused esthetic problems due to discoloration or staining as in esthetic restoration. Many researches and reports have treated the problems and accomplished esthetic improvement. But these researches and reports dealt with general food colors or beverages, not with fermented foods. PURPOSE: This study is designed to assess what fermented foods, such as soy sauce, gochujang, and toenjang that many of Koreans have taken in, influence on the color and hardness variation of denture base acrylic resins. MATERIALS AND METHODS: For the procedure, twelve disks per 4 denture base acrylic resins were fabricated with a thickness of 2mm and 16mm in diameter. Each seven specimen were measured for discoloration with spectrophotometer, while the others, five specimen, for surface hardness change with Barcol hardness tester, over time. Each 12 specimen were immersed into the 4 beakers of fermented foods(soy sauces, gochujangs, toenjangs, deionized water), and L*, a*, and b* values were measured for the color difference(_E*), on the 1st, 7th, and 28th day with spectrophotometer, with the measurement of surface hardness change. Each data observed was processed statistically. RESULTS: The findings are as follows; Discoloration 1. All of denture base resins was not influenced by the kind of fermented foods, except for QC20. 2. Soy sauce and red pepper paste caused more change for denture base resins than deionized water and soy bean paste, except for Perform. 3. Most significant change was shown in Lucitone199., whereas Perform. results in the least change for all immersed solution, with no statistical significance. Hardness change 1. Barcol hardness values in deposited specimens have been changed low degree, but with significant statistical change according to the kind of food and duration. 2. Lucitone199. has significantly lower Barcol hardness value than others do. CONCLUSION: Based on the above results, it suggests that the habitual intake of fermented foods is not helpful for the color stability of denture base acrylic resins because Soy sauce and red pepper paste mainly caused discoloration and surface hardness change. Particularly Lucitone199. shows specific discoloration and low surface hardness values. Therefore, it is recommended giving caution patients with denture of Lucitone199. especially against the habitual intake of fermented foods like soy sauce and red pepper paste.

PURPOSE: The aim of this study was to compare the retention of mini implant overdenture by the number, the type of magnetic attachment, and the directions of applied dislodging force. MATERIALS AND METHODS: The experimental groups were designed by the number and type of magnetic attachment. Twenty samples were tested with Magden implants. Each attachment was composed of the magnet assembly in overdenture sample and the abutment keeper in a mandibular model. Dislodging forces were applied to the overdenture samples (50.0 mm/min) in 3 directions. The loading was repeated 10 times in each direction. The values of dislodging force were analyzed statistically using SPSS at 95% level of confidence. RESULTS: The retentive force of group 2 was greater than that of group 1 in both types of attachment in every direction (P < .05). Oblique retentive force of flat type magnetic attachment was higher than that of cushion type attachment in both groups (P < .05). In group 1, oblique retentive force showed the highest and anterior-posterior retentive force showed the lowest value in both attachment types (P < .05). In group 2, both types of attachment showed the lowest retentive force with anteriorposterior direction of dislodging force (P <.05). CONCLUSION: Proper retentive properties for implant overdenture were obtained, regardless of the number and type of magnetic attachment. In both types of magnetic attachment, the greater retentive force was attained with more implants. Oblique retentive force of flat type magnetic attachment was greater than that of cushion type. Among all subgroups, anterior-posterior retentive force was the lowest among three different directions of dislodging force.
