BACKGROUND: The aim of this study is to quantitatively evaluate the effect of rhBMP-2 for repair of bone defects after cyst enucleation using the osteogenesis index (OI). METHODS: Under general anesthesia, 10 patients (12 lesions) underwent oral or maxillofacial surgery for cyst enucleation. Postoperatively, 12 lesions were divided into two groups: group A (six lesions) was treated with absorbable collagen sponge (ACS) in combination with rhBMP-2, and group B (six lesions) was treated with ACS alone. After 3 months, cone-beam computed tomographic scans were obtained to measure changes in the volume of the lesions. We then calculated the OI of each group at two different Hounsfield units to determine any statistically significant difference between these two groups (Mann–Whitney U test). RESULTS: As tested at the level of new bone, the mean OI was 72.37% in group A and 55.08% in group B —a statistically significant difference (p=0.041). As tested at the level of mature bone, the mean OI was 27.47% in group A and 18.88% in group B, but the difference was not statistically significant (p=0.394). CONCLUSIONS: The application of rhBMP-2 after maxillofacial cyst enucleation accelerated new bone formation in the bone defects. Thus, the use of rhBMP-2 in combination with ACS may be considered an alternative to conventional bone grafting in some patients with postoperative bone defects.

OBJECTIVES: The purpose of this study was to evaluate the clinical usefulness of the protein/creatinine ratio of a spot urine specimen for early detection of proteinuria in the pregnancy induced hypertension and to suggest optimum cut-off value of that. STUDY DESIGN: A spot urine specimen and 24 hour urine collection for the proteinuria were ordered for 36 women admitted to obstetric unit for pregnancy induced hypertension and ROC curve analysis was performed to evaluate the usefulness of the protein/creatinine ratio of a spot urine specimen and to suggest optimum cut-off value. RESULT: The protein/creatinine ratio of spot urine positively correlated well with 24 hour urine proteinuria. (r=0.4322, p=0.0085) and the optimum cut-off value of the protein/creatinine ratio of a spot urine specimen to maximize the diagnostic accuracy was 5.0(Youden's index=0.66). CONCLUSION: We conclude that the protein / creatinine raio of a spot urine specimen may be a simple and inexpensive method for evaluation of proteinuria in the pregnancy induced hypertension when frequent determinations are necessary. This should improve clinical care, especially when managing hypertensive pregnant women as outpatients.

OBJECTIVES: The aim of this study was to investigate the gender differences of direct aggression and relational aggression in Korean elementary and middle school students. METHODS: Parents of 946 elementary school students(age 9.54±1.72 years, 485 boys, 461 girls) completed the Child Behavior Checklist(CBCL). Six-hundred-and-three middle school students(age 13.98±0.93 years, 301 boys, 302 girls) completed the Youth Self-Report(YSR). Independent t-test, chi-square test, and Fisher's exact test were used. RESULTS: Boys had significantly higher direct aggression scores than girls in elementary school students(p<0.001). There was no significance gender difference of relational aggression in elementary school students(p=0.235). In middle school students, boys had significantly higher direct aggression than girls(p=0.017), and girls had significantly higher relational aggression compared to the boys(p<0.001). CONCLUSION: Our results suggest the presence of gender differences in manifestation of aggression subtypes in Korean elementary and middle school students. These gender differences should be taken into account in prevention and intervention approaches of aggression in children and adolescents.

PURPOSE: Effective hemodialysis for a patient with end-stage renal disease (ERDS) is dependent upon a durable, low-morbidity vascular access. Although It is generally agreed that the distal radiocephalic fistula originally discribed by Brescia and Cimino is the most effective primary access constrruction, no consensus exists regarding primary and secondary alternatives for patients with inadequate of failed rediocephalic prodedures. Many options are available, but the relative value of these alternative operations is unclear. Therefore the place of the basilic vein in secondary acccess construction needs to be assessed. We evaluated if the basilic vein can be used to construct a durable, low-morbidity access. METHODS: A native brachio-basilic arterio-venous fistula with superficial transposition has been performed, for lack of usuable vein on 54 forearm in 47 patients from August 1995 to October 1999 (Male: 15, female: 32) with mean age 51 years (26 to 70 years). RESULTS: The main cause of renal insufficiency were: diabetes 27 (57.4%), hypertensive 19 (40.4%), renal tuberculosis 2 (4.3%) and renal cyst 1 (2.1%). The waiting period before vascular access puncture has been 28 6 days. Eight (17.0%) stenosis has been detected and, forearm and/or hand edema occured in three (6.4%); thrombosis in two (4.3%); bleeding in two (4.3%); pseudoaneurysm in one. Through the follow-up periods of 50 months, the primary patency was 80.9% at 12 months and 78.7% at 24 months. CONCLUSION: The brachio-basilic fistula with superficial transposition of basilic vein is a valuable vascular access for diabetes, female old patients, and can remain an alternative method for even younger patients by avoiding the installation of artificial graft after failed forearm arteriovenous fistula.

PURPOSE: The aim of this study was to investigate the effect of perinatal risk factors on brain maturation and the relationship of brain maturation and neurodevelopmental outcomes with brain maturation scoring system in brain MRI. METHODS: ELBWI infants born at the Seoul National University Children's Hospital from January 2006 to December 2010 were included. A retrospective analysis was performed with their medical record and brain MR images acquired at near full term. We read brain MRI and measured maturity with total maturation score (TMS). TMS is a previously developed anatomic scoring system to assess brain maturity. The total maturation score was used to evaluate the four parameters of maturity: (1) myelination, (2) cortical infolding, (3) involution of glial cell migration bands, and (4) presence of germinal matrix tissue. RESULTS: Images from 124 infants were evaluated. Their mean gestational age at birth was 27.1+/-2.1 weeks, and mean birth weight was 781.5+/-143.9 g. The mean TMS was 10.8+/-2.0. TMS was significantly related to the postmenstrual age (PMA) of the infant, increasing with advancing postmenstrual age (P<0.001). TMS showed no significance with neurodevelopmental delay, and with brain injury, respectively. CONCLUSION: TMS was developed for evaluating brain maturation in conventional brain MRI. The results of this study suggest that TMS was not useful for predicting neurodevelopmental delay, but further studies are needed to make standard score for each PMA and to re-evaluate the relationship between brain maturation and neurodevelopmental delay.

PURPOSE: To determine the patterns of evaluation and treatment in the patient with early breast cancer treated with conservative surgery and radiotherapy and to improve the radiotherapy techiniques, nationwide survey was performed. MATERIALS AND METHODS: A web-based database system for Korean Patterns of Care Study (PCS) for 6 common cancers was developed. Two hundreds sixty-one randomly selected records of eligible patients treated between 1998~999 from 15 hospitals were reviewed. RESULTS: The patients ages ranged from 24 to 85 years(median 45 years). Infiltrating ductal carcinoma was most common histologic type (88.9%) followed by medullary carcinoma (4.2%) and infiltrating lobular carcinoma (1.5%). Pathologic T stage by AJCC was T1 in 59.7% of the casses, T2 in 29.5% of the cases, Tis in 8.8% of the cases. Axillary lymph node dissection was performed in 91.2% of the cases and 69.7% were node negative. AJCC stage was 0 in 8.8% of the cases, stage I in 44.9% of the cases, stage IIa in 33.3% of the cases, and stage IIb in 8.4% of the cases. Estrogen and progesteron receptors were evaluated in 71.6%, and 70.9% of the patients, respectively. Surgical methods of breast-conserving surgery was excision/lumpectomy in 37.2%, wide excision in 11.5%, quadrantectomy in 23% and partial mastectomy in 27.5% of the cases. A pathologically confirmed negative margin was obtained in 90.8% of the cases. Pathological margin was involved with tumor in 10 patients and margin was close (less than 2 mm) in 10 patients. All the patients except one recieved more than 90% of the planned radiotherapy dose. Radiotherapy volume was breast only in 88% of the cases, breast+supraclavicular fossa (SCL) in 5% of the cases, and breast+SCL+posterior axillary boost in 4.2% of the cases. Only one patient received isolated internal mammary lymph node irradiation. Used radiation beam was Co-60 in 8 cases, 4 MV X-ray in 115 cases, 6 MV X-ray in 125 cases, and 10 MV X-ray in 11 cases. The radiation dose to the whole breast was 45~9.4 Gy (median 50.4) and boost dose was 8~20 Gy (median 10 Gy). The total radiation dose delivered was 50.4~70.4 Gy (median 60.4 Gy). CONCLUSION: There was no major deviation from current standard in the patterns of evaluation and treatment for the patients with early breast cancer treated with breast conservation method. Some varieties were identified in boost irradiation dose. Separate analysis for the datails of radiotherapy planning will be followed and the outcome of treatment is needed to evaluate the process.
