  • Purpose: The purpose of this study was to elucidate the efficacy and safety of carbonate apatite (CO3Ap) granules in 2-stage sinus floor augmentation through the radiographic and histomorphometric assessment of bone biopsy specimens. Methods: Two-stage sinus floor augmentation was performed on 13 patients with a total of 17 implants. Radiographic assessment using panoramic radiographs was performed immediately after augmentation and was also performed 2 additional times, at 7±2 months and 18±2 months post-augmentation, respectively. Bone biopsy specimens taken from planned implant placement sites underwent micro-computed tomography, after which histological sections were prepared. Results: Postoperative healing of the sinus floor augmentation was uneventful in all cases. The mean preoperative residual bone height was 3.5±1.3 mm, and this was increased to 13.3±1.7 mm by augmentation with the CO3Ap granules. The mean height of the augmented site had decreased to 10.7±1.9 mm by 7±2 months after augmentation; however, implants with lengths in the range of 6.5 to 11.5 mm could still be placed. The mean height of the augmented site had decreased to 9.6±1.4 mm by 18±2 months post-augmentation. No implant failure or complications were observed. Few inflammatory cells or foreign body giant cells were observed in the bone biopsy specimens. Although there were individual differences in the amount of new bone detected, new bone was observed to be in direct contact with the CO3Ap granules in all cases, without an intermediate layer of fibrous tissue. The amounts of bone and residual CO3Ap were 33.8%±15.1% and 15.3%±11.9%, respectively. Conclusions: In this first demonstration, low-crystalline CO3Ap granules showed excellent biocompatibility, and bone biopsy showed them to be replaced with bone in humans. CO3Ap granules are a useful and safe bone substitute for two-stage sinus floor augmentation.

  • Objectives: The purpose of this study was to examine whether Temporomandibular Joint Balance Appliance-Golf (TBA-G) can improve postural control ability of healthy adults. Methods: Twenty participants (10 male, 10 female) aged 20 to 39 years were involved. Postural control ability of all participants was assessed before and after applying TBA-G with Balance $Master^{(R)}$ system. Modified clinical test sensory interaction on balance (mCTSIB), unilateral stance, weight bearing and rhythmic weight shift were used to evaluate postural control ability. Results: After applying TBA-G, mCTSIB on a firm plate with eyes open increased from 0.2 to 0.23 (p<0.05) but directional control was improved in slow and moderate velocity of front/back rhythmic weight shift test (P<0.05). In two cases with postural imbalance, most of the postural control measures improved after applying TBA-G. Conclusions: The results suggest that TBA-G could improve balance control ability. A larger controlled trial is needed to determine more accurately the effect of TBA-G on balance control ability.

  • The aim of this study was to evaluate the appropriateness of some kinds of surgery and admission, such as cesarean section (C/S), cholecystectomy, and pediatric pneumonia. For appropriateness evaluation, we ourselves developed some criteria, which were included in the category of explicit and linear criteria, with the assistance of specialists of relevant clinical field. The evaluation of appropriateness was performed by two family physicians. The major findings were as follows: 1. For cesarean section, 77.6% of deliveries were determined to be 'appropriate', but the level of appropriateness was not significantly different among hospitals and between hospital groups by size. The most freqeunt indication of C/S was repeated operation, followed by cephalopelvic disproportion (CPD). The labor trials for vaginal delivery among repeated C/S and CPD cases were performed in 24.5% of pertinent deliveries. 2. About 73.8% of cholecystectomy cases was appropriate to one of the surgical indications, without significant differences among hospitals. Of surgical indications, 'sufficiently frequent and intense symptom recurrence' was the most frequent, and 'confirmed acute cholecystitis' was the second. 3. Of children admitted due to pneumonia, only 57.4% of cases satisfied admission criteria, and the level of appropriateness of admission was different among hospitals. The common reasons fur admission were 'failure to initial treatment', 'suspected bacterial pneumonia', 'young infant', etc. We could find that there were differences of quality among hospitals in some procedures, especially in the pediatric pneumonia and labor trial before C/S, which suggested that the implementation of quality assurance activiteis would be necessary in this country. In this study, we used some simple and primitive research tools and the numbers of subjects and tracer procedures were limited. So advanced studios with plentiful subjects and more representative diseases or procedures should be tried.

  • 소아치과 임상에 있어서 교정용 밴드는 매우 다양한 용도로 일상적으로 사용되고 있다. 그러나 교정용 밴드와 치아 사이에 시멘트가 불균일하게 분포되어 치아 법랑질 탈회나 치은염이 유발됨을 간혹 보게 된다. 본 연구는 이러한 문제를 근원적으로 차단할 수 있는 균일한 시멘트 층을 유지 한 밴드 장착방법을 모색할 목적으로 시도되었다. 발치된 상하 제 1 대구치를 복제한 치아모형에 이에 적합한 교정용 밴드를 선택하여 접착용 시멘트로 세 가지 방법으로 접착시켰다. 방법 1에서는 접착용 시멘트를 밴드 내면에만 도포하였고, 방법 2에서는 접착용 시멘트를 밴드 내면과 치아의 축면에 도포, 방법 3에서는 접착용 테이프를 밴드의 상연에 부착한 상태에서 밴드 내면에 접착용 시멘트를 도포하였다. 접착용 시멘트가 경화된 후 밴드를 치아에서 벗겨내고 내면의 시멘트 분포상태를 관찰하였다. 실험 결과, 밴드 내면에만 시멘트를 도포한 방법 1의 경우보다는 방법 2와 3의 경우에 시멘트가 더 균일하게 도포된 것으로 나타났다. 따라서 교정용 밴드를 장착하는 과정에서는 접착용 시멘트를 밴드 내면에만 도포하는 방법보다는, 치면에도 시멘트를 가하거나 잉여 시멘트의 교합면측 탈출구를 봉쇄하는 등의 방법이 균일하게 도포된 시멘트 접착을 달성하는 좋은 대안이 될 것으로 판단되었다.

  • Background: Helicobacter pylori plays an important role in gastric cancer and typical eradication regimens are no longer effective in many countries, including Thailand. The aim of our study was to compare the effect of Lactobacillus delbrueckii and Streptococcus thermophillus on tailored triple therapy for Helicobacter pylori eradication. Materials and Methods: This prospective single-center study was conducted in Thailand. Helicobacter pylori associated gastritis patients were randomized to 2 groups: group 1 (n=100) was tailored triple therapy with placebo (esomeprazole 20 mg bid, clarithromycin 500 mg bid or metronidazole 400 mg tid if clarithromycin resistance and amoxicillin 1000 mg bid), and group 2 was tailored triple therapy plus pretreatment with probiotic containing yogurt. Successful eradication was defined as both negative histology and negative rapid urease test at four weeks after treatment. Results: A total of 200 infected patients were enrolled. PP analysis involved 194 patients: 96 in the tailored triple therapy with placebo group (group 1) and 98 the in tailored triple therapy plus pretreatment with probiotic containing yogurt group (group 2). Successful eradication was observed in 170 (87.6%) patients; by PP analysis, the eradication rate was significantly higher in group 2 (P = 0.04, 95%CI; 0.02-0.13) than in group 1. ITT analysis also showed that the value was significantly higher in the tailored triple threapy plus pretreatment with probiotic containing yogurt group (group 2) (89/100; 89%) than in the tailored triple therapy with placebo group (group 1) (P= 0.01, 95%CI; 0.04-0.15). In terms of adverse events, there was no significant difference between the two groups. Conclusions: Pretreatment with probiotic containing yogurt can improve Helicobacter pylori eradication rates with tailored triple therapy. Adding probiotics does not reduce adverse effects of the medication.

  • Cage layer waste and sudex grass were ensiled in the proportions of 0:100, 30:70, 40:60 and 50:50 wet basis, respectively. The influence of ensiling cage layer waste on Salmonellae, Shigella, Proteus, and total number of colony forming units (CFU) was investigated. The nutritive value of the silages was evaluated in a digestion trial. The experiment was conducted with 24 wethers allotted to four silages. Initial samples of cage layer waste showed $0.11{\times}10^6$ CFU and salmonellae, Shigella and Proteus were present. Ensiling was effective in complete elimination of all the pathogens. Dry matter, crude protein and ash contents were increased linearly (p < .01) with the increase of cage layer waste in the silages ($358g{\cdot}kg^{-1}$ to $484g{\cdot}kg^{-1}$; $76.3g{\cdot}kg^{-1}$ to $183.2g{\cdot}kg^{-1}$ and $38.5g{\cdot}kg^{-1}$ to $169.4g{\cdot}kg^{-1}$; DM basis, respectively). Water solubles carbohydrate values for silages were 38.3, 22.5, 20.1 and $20.0g{\cdot}kg^{-1}$ DM basis, respectively. Ensiling decreased the pH values for all the silages and the decrease was higher for sudex grass ensiled alone than grass ensiled with cage layer waste. Lactic acid concentration in silages increased linearly (p < .01) with the increase of cage layer waste. The apparent digestibilities of DM, OM and CP for the animals fed sudex grass silage alone were 496.0, 516.1, $496.7g{\cdot}kg^{-1}$ DM basis respectively. However, digestibilities of all the components were higher (p < 0.01) for the animals fed silages containing cage layer waste. Among waste containing diets, the digestibilities of all the components showed quadratic affect (p < 0.01), increased for silages containing 30 and 40% cage layer waste and decreased when the level of waste increased from 40 to 50%. The results indicated that cage layer waste can be used upto 40% in ruminant diet as a source of N without any adverse effect on the health of animals. Ensiling appeared to be feasible and effective method for eliminating the pathogen present in cage layer waste.

  • Objectives : The knee pain is the main reason of getting acupuncture treatment. In order to have confidence in the results of a study, it is necessary to establish that questionnaire is both valid and reliable in questionnaire related study. The aim of this study was to review the instruments that are currently in sue for assessing the knee joint. Methods : A literature study was performed to choose appropriate scales for assessment for pain and the function of the knee. Theoretically based scales were selected for review. Therefore, 18 scales for knee and 9 scale for pain were reviewed. the status of scales involved in knee treatment of acupuncture throughout several countries was evaluated. Results & Conclusion : Lysholm Knee Scoring Scale, Cincinnati knee rating system(CKRS) are adequate for ligament injury in knee. International Knee Documentation Committee scoring system(IKDC) may become a publication requirement for journals in view of the international standing of the committee. The available outcome measure for use in osteoarthritis are Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC), Lequesne Functional Severity Index(LFI) and Knee Injury and Osteoarthritis Outcome Score(KOOS), and in rheumatoid arthritis are McMaster-Toronto Arthritis patient function preference questionnaire(MACTAR), Quality of Life-Rheumatoid Arthritis Scale(QoL-RA Scale). Visual analog scale(VAS), verbal rating scale(VRS) are commonly used for the standard pain scale. For long term follow-up study The Medical Outcomes Study Short Form-36(SF-36), Arthritis Impact Measurement Scales(AIMS), Health Assessment Questionnaire(HAQ) should be included. Each measurement has its own composition and characteristics. Their validity, reliability, responsiveness and practical characteristics were already evaluated. We found 20 domestic and 28 overseas papers about knee treatment using acupuncture assessed with knee scales.
