STATEMENT OF PROBLEM: Proper proximal contact is important for maintaining and stabilizing the dental arch. However, the proximal contact strength (PCS) is not a constant value and can be affected by a variety of factors. PURPOSE: This study examined the influences of postural changes on the posterior PCS. MATERIAL AND METHODS: Twelve adults with a normal occlusion and had not undergone prosthetic treatment or proximal restoration were participated in this study. A metal strip was inserted into the proximal surface and removed at a constant velocity. The contact strength was measured in every contact point between canine to second molar in both arches. The PCSs were obtained initially in the upright position, secondly in the supine position and finally in the upright position again. All measurements were repeated after a 2 hour period. Statistical analysis was carried out using the Friedman test (P < .05). RESULTS: Generally, a decrease in PCS occurred when the posture was changed from the initial upright to supine position, while it increased when the posture was changed from the supine to upright position. A significant change was observed in all areas except for between the canine-first premolar in the maxilla and between the first molarsecond molar in the mandible areas. CONCLUSION: The posterior PCS, which dentists generally believe to be a static feature of occlusion, is affected significantly by posture.

2.Early experience of hyperbaric oxygen therapy in radiation-induced cystitis.
Korean Journal of Urology 1992;33(6):1101-1104
The effects of hyperbaric oxygen therapy have been documented in 10 patients with radiation-induced cystitis refractory to conventional management. Seven patients were treated for 40-70 consecutive days, 90 minutes each day with 100 per cent oxygen at 2.4 atmospheres absolute pressure in a multiplace unit. Seven patients achieved the relief of gross hematuria and improvement of bladder irritative symptoms without side effect for an average 16.7 months (range 6 to 27 months). Hyperbaric oxygen therapy was stopped in three patients because of febrile sense in trunk, pneumonia and cancer recurrence. This experience suggests that hyperbaric oxygen therapy might be considered the primary treatment of patients with symptomatic radiation-induced cystitis.

PURPOSE: The aim of this study was to assess the mid-term results of primary cementless total hip arthroplasty (THA) using Summit® stems. MATERIALS AND METHODS: One hundred twenty-eight arthroplasties in 121 patients who were performed THA from December 2004 to March 2013, were reviewed retrospectively a minimum of 4 years follow-up (mean age, 60.3 years; mean postoperative follow up period, 86.3 months). For a clinical evaluation, the Harris hip score (HHS) was used to assess outcome. Radiographic evaluation was done through spot welds, subsidence, stress shielding, canal filling. RESULTS: The mean HHS was 69.8 points preoperatively, and it improved significantly to 96.3 points at the final follow-up. Postoperatively, 10 patients experienced thigh pain and 7 patients showed a moderate limping gait. There was not only early stem subsidence but there was no more subsidence at last follow up. One hundred eighteen hips showed radiographic signs of stem bone ingrowth, and 10 hips showed fibrous ingrowth at the last follow-up. Stress shielding occurred in 85 hips and third degree stress shielding was observed in 6 hips. Complication arose in 10 hips due to dislocation. Although revisions due to recurrent dislocations led to acetabular component revision in one hip, no revisions arose due to isolated aseptic loosening of the femoral component. CONCLUSION: The clinical and radiological mid-term results of primary THA using Summit® stems revealed solid initial fixation and bone ingrowth stable fixation. Considering the satisfactory clinical results, Summit® stems may be a good treatment option in Korean patients who were required hip arthroplasty

BACKGROUND: Nowadays, as public awareness of t,he Acquired immunedeficiency syndrome(AIDS) epidemic was increasing, athletes have become more concerned about their risk of infection with human immunedeficiency virus(HIV) since it, was announced that Magic Johnson, hero of basketball in the United States, was infected. Because there are no exact cure method about AIDS, the only treatment is prevention through the education and awareness of AIDS. Therefore, we researched the athletes knowledge of AIDS to provide the b#asis of preventive methods. METHODS: A questionnaire was given directly to the 110 wrestling and taekwondo athletes attending a sports college. RESULT: Athletes are all men and their mean age is 24.6 years old. Concerning the question of latent period, 54.5% had correct answer that AIDS development took more than several years after HIV infection. The person who had educated about the preventive methods of infection during the sports was 4.6%. The person who answered AIDS athletes should be excluded from the sports was 64.5% and the reason of exclusion was the risk of infection through the small bleeding(49.8%), sweating(38.0%), and simple skin cont,acts(19. 7%) during the sports. The correct recognition rate of preventive method of infection during the sports was 51.8 to 62%. Concerning the risk routes and behaviors of infection during daily life, most of them recognized correctly(from 76,3% to 99.0% by each item), but some have also misconception about transfusion(61.0%), skin contact(33%) and mosquitos bite(30%) etc. CONCLUSION: Almost all of athletes recognized correctly the risky behavior of sex and blood in transmission of infection, but some have also misconception in daily activities, e.g. transfusion and mosquitos. Many persons answered AIDS infected athletes should be excluded from the sports and they didnt receive any education about preventive methods of AIDS infection during the sports. The knowledge of preventive methods of infection recommended during the sports was relatively high.
