If orthodontists and restorative dentists establish the interdisciplinary approach to esthetic dentistry, the esthetic and functional outcome of their combined efforts will be greatly enhanced. This article describes satisfying esthetic results obtained by the distribution of space for restoration by orthodontic treatment and porcelain laminate veneers in uneven space between maxillary anterior teeth. It is proposed that the use of orthodontic treatment for re-distribution of the space and the use of porcelain laminate veneers to alter crown anatomy provide maximum esthetic and functional correction for patients with irregular interdental spacing.

Perigraft seroma is uncommon complication of polytetrafluoroethylene(PTFE) grafts applied as an arteriovenous shunt for hemodialysis. It is a collection of clear, sterile fluid confined to nonsecretory fibrous pseudomembrane, most commonly localized around the middle and distal portion of graft. The possible etiologic factors of perigraft seroma include poor graft incorporation, mechanical graft damage caused by alcohol and povidone-iodine, intraoperative streching of the graft, variations in quality control at the time of manufacture and contributing factors such as anemia and coagulopathy in uremia. The best strategy for management of perigraft seroma is not clear. spiration or drainage alone is not effective, and some authors advocate graft removal. We report a case of perigraft seroma around arterial end of PTFE graft along with a brief review of the literatures.

STUDY DESIGN: This is a retrospective study analyzing the clinical results of various surgical methods for the treatment of delayed posttraumatic kyphosis. OBJECTIVES: The purposes of this study are to define the risk factors of delayed postraumatic kyphosis and to establish a rational therapeutic guideline for the treatment of established kyphosis. METHODS: Sixteen cases of surgically treated delayed posttraumatic kyphosis were analyzed. Their initial injuries were burst type in 10, flexion-distraction in 5 and uncertain in l. Initial treatments were conservative in 10 and surgical in 6. Treatments for established kyphosis were posterior fusion in 2, anterior fusion in 5, combined anterior-posterior fusion in 9. Anterior decompression was carried out in 5 treated with anterior fusion and in 4 treated with combined anterior-posterior fusion. RESULTS: Mean follow-up was 2.7 years. The mean preoperative kyphosis of 28.6。 was reduced to 18.5。 (35.3% correction) with most pronounced correction in the group with combined anterior and posterior stabilization(44.8% correction). Early loss of correction averaged 2.7。 (18.5%) with least loss in the combined anterior-posterior group. Neurological improvement was related to the duration of the symptoms(P < 0.05). Back pain was improved in all patients. CONCLUSIONS: Thoracolumbar fractures with initial three column injuries or those rendered unstable by laminectomy are highly susceptible to development of delayed posttraumatic kyphosis; Combined anterior and posterior fusion offered the most satisfactory result in correction and stabilization of the deformity; Neurologic improvement was more pronounced with shorter duration of the symptoms.

BACKGROUND: Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis that can affect many organs of the body but usually affects the lungs. The prevalence of TB in Korea is considerably higher than that in other countries with similar economic levels, and is much higher in elderly people. Pharmacotherapy is important in the treatment of TB and requires relatively high compliance for a prolonged duration. METHODS: We analyzed sample data of elderly patients obtained from the Health Insurance Review and Assessment Service. We used logistic regression analysis and frequency analysis to identify factors that could affect prevalence of TB in elderly patients, compliance with prescribed medication regimes in these patients, and use of medical institutions. Korean Standard Classification of Diseases, version 7 (KCD-7) was used to diagnose pulmonary TB, and medications were analyzed using Korean standardized drug classification codes. RESULTS: 1,276,331 patients were analyzed in the sample of the elderly population, and 16,658 TB patients were included in the study. The mean age of the TB patients was 76.19 years (SD 6.899). A total of 699 patients were prescribed isoniazid, rifampicin, ethambutol, or pyrazinamide at least once. Of these, 352 (50.4%) were prescribed all four medications and 101 (14.4%) were prescribed only isoniazid, rifampicin, and ethambutol. The mean duration of prescription was 28.75 days (SD 36.13). CONCLUSION: In the elderly population, old age and poor socioeconomic conditions correlated with TB prevalence. Most patients did not meet the criteria for effective pharmacotherapy of TB.

Objectives: The purpose of this animal research was to compare bone regeneration in augmented rabbit maxillary sinuses treated with demineralized particulate human-tooth graft and anorganic bovine bone by immunohistochemical analysis. Materials and Methods: Piezoelectric bilateral sinus augmentation was performed in eight adult rabbits. In the control group, anorganic bovine was grafted in the maxillary sinus following elevation of the sinus membrane. In the experimental group, demineralized human particulate tooth bone was grafted in the sinus. Bone regeneration in augmented sinuses was evaluated by immunohistochemical analysis using various markers of osteoprogenitor cells. Results: The number of bromodeoxyuridine-labeled cells was significantly higher in the experimental group than in the control group at eight weeks. The immunoreactivity of proliferating-cell nuclear antigen was increased slightly in the experimental group relative to the control group at eight weeks. Other bone markers were expressed equally in the two groups. Conclusion In the rabbit maxillary sinus, higher osteoinduction was correlated with demineralized human particulate tooth bone grafting than with anorganic bovine grafting.

BACKGROUND: It is necessary to exercise in Continuous Ambulatory Peritoneal Dialysis (CAPD) patients but it's difficult because of their physical condition and little motivation. The purpose of this study was to evaluate the effects of the walking exercise program on health status in CAPD patients. METHODS: A nonequivalent control group with pre- and post-test was designed to examine the effects of the program. Data collection was done from December, 2002 to June, 2003. The study participants were selected according to the criteria among the patients who were receiving CAPD at the department of Kidney Center, NIHC Ilsan hospital. The walking exercise program was consisted of an exercise education protocol, an exercise prescription, and a counselling protocol based on a framework of self-efficacy promotion. The exerciser group which was composed of 19 participants was educated based on an exercise education protocol and carried out walking exercise for two to four times a week upon taking verbal persuasion biweekly through telephone or face-to-face interview for 12 weeks, while 17 participants in control group were received no intervention. RESULTS: There was significant differences between two groups; the exerciser group showed better physical function (p=0.03), higher VO2 max (p=0.01) and higher serum albumin level (p=0.02) than the results of control group. However, there were no differences in lipid metabolism. CONCLUSION: The walking exercise program was found to have an effect to increase health status of CAPD patients. The results provided evidences for the importance of continuous physical activity in CAPD patients.

The prenatal diagnosis of spina bifida includes the combined use of maternal serum alpha-fetoprotein (MSAFP) screening and fetal sonography. On ultrasonogram, spina bifida is characterizd by visualization of the spinal defect and associated cranial abnomalities: the Lemon sign, the Banana sign, ventriculomegaly, small biparietal diameter, and obliteration of the cisterna magna. We should now be able to rely on ultrasound as the main technique for diagnosis of spina bifida when MSAFP is elevated. Recently, we have experienced three cases of spina bifida diagnosed with meningomyelocele, lemon sign, banana sign and ventriculomegaly on ultrasonogram at respectively 18+3, 18, and 18+6 weeks of gestation. We present these cases with a brief review of literatures.
