This study was conducted on 342 patients(male 157, female 185)aged 8 to 15 years old, who visited Dankook University Dental Hospital. Pre-orthodontic treatment orthopantomograms were used to assess the dental calcification stages of mandibular 3rd molar, 2nd molar, 2nd premolar and 1st premolar by 8 stages.(by Demirjian) Hand-wrist radiogrms were used to evaluate the skeletal maturity in 11 stages.(by Fishman) Following results were obtained after investigating the correlationship between dental calcification and skeletal maturity. 1. Chronologic age showed high correlation to dental calcification and skeletal maturity. 2. Dental calcification and skeletal maturity showed high correlation and no statistical difference was observed between male and female. 3. SMI stages 1 to 4 showed high statiscal significance to mandibular 2nd molar, 2nd premolar and 1st premolar. SMI stages 5 to 8 showed high stastical significance to mandibular 2nd molar, 2nd premolar. SMI stages 9 to 11 showed high statistical significance to mandibular 3rd molar.

Systemic capillary leak syndrome (SCLS) is a rare devastating condition that is caused by unexplained marked capillary hyperpermeability, resulting in hypovolemic shock, hemoconcentration, and hypoproteinemia. Most patients have prodromal symptoms such as non-specific gastrointestinal symptoms, myalgia, or dizziness. In the current case, we observed the patient with recurrent SCLS show perivascular lymphocytic infiltration on skin biopsy and eosinophilic infiltrates on random biopsies from duodenum to colon. This finding might be due to distinct eosinophilic enterocolitis or secondary to SCLS. However, there has been rare data for the prevention of the recurrent attack of SCLS, although the mortality is high. Therefore, we report a case of frequently relapsing SCLS responding to the corticosteroid therapy.

A large number of terms has been applied to this clinical and pathophysiologic complex, all of which are encompassed by the designation ARDS. The use of this term,however, should not obscure the fact that the initial insults and mechanisms of lung injury vary and that therapy should be directed not only toward the secondary alterations in pulmonary function but toward the initiating event or events as well. In therapy, the use of continuous positive-pressure ventilaion(CPPV) incorporating PEEP has a well-documented role in the management of patients with ARDS. The veneficial effect of this pattern of ventilation is mainly attributable to the increase in FRC that it produces. As previously discussed, several factors combine to reduce lung volumes in patients with ARDS. Positive end-expiratory pressure overcomes threade by producing a constantly positive distending pressure across the walls of airways and alveoli; this reestablishes their patency and increases FRC. We report a case of ARDS after operation for Vesico-cervical fistula developed in a 34 years old woman and the relevant literature has been reviewed.

The patients receiving epidural morphine were divided into two groups. One group(A group): epidural injection of 2 mg morphine mix with physiologic saline 10 ml were given to 13 patients with acute pain after surgery under epidural or light general anesthesia and chronic pain of chronic disease. The other group): epidural or caudal injection of 2 mg morphine mix with 2% lidocaine 400 mg were given to 5 patients. In A group, assesed single or continuous epidural injection. In B group, assessed epidural or caudal injection. All cases had considerable amelioration of pain which commenced with 2 to 15 minutes and was effectiveness 2 to 59 hours. Epidural morphine injection did not cause sympathetic depression or bladder dysfunction and it's analgesia was segmental.

Sacroccygeal teratoma(SCT) occurs in every 40,000 births and is the most common tumor in newborns. SCT predominantly develops in females and is almost always located in the gonadal or coccygeal region. Althoug the majority of tumors are usually benign, malignant degeneration is common and the prognosis is generally guraded. Therefore the early prenatal diagnosis and treatment are very important. The authors observed a case of SCT which was diagnosed by ultrasonagrapy at 30 weeks' gestation following IVF-ET procedure. Surgical removal of SCT of newborn was performed successfully following cesarean delivery at 38 weeks' gestation. The authors report this case with a brief review of the literatures.

OBJECTIVE: The aim of this study was to investigate the relationship between follicular blood flow and the follicular fluid vascular endothelial growth factor (VEGF), and nitric oxide (NO) concentrations, and to determine which factor might be a better predictor of the outcome of IVF-ET. METHODS: In our prospective study, forty-seven cycles who underwent in vitro fertilization with tubal factor (25 cycles) and male factor (22 cycles) at the infertility clinic of Pusan National University Hospital from Feb. 2002 to June 2002 were assessed. Follicular blood flow was estimated on the day of hCG administration. Each follicular fluid was collected at the oocyte retrieval and follicular fluid VEGF and NO concentrations were assessed. According to the age of patients, the cause of infertility, and pregnancy rate, follicular blood flow and follicular fluid VEGF and NO concentrations were measured. RESULTS: Of 47 cycles, 18 cycles were pregnant (38.3%). Follicular blood flow was significant higher in the pregnant group compared to the nonpregnant group (p<.05), but there was no statistical significantly difference in the age and infertility cause. Follicular fluid concentrations of VEGF and NO were not statistically different in age, infertility cause, and pregnancy outcome. As follicle size increases, the follicular blood flow and follicular fluid VEGF concentrations increased significantly, but follicular fluid NO concentrations decreased. There was no correlation between VEGF and NO concentrations in follicular fluid by linear regression analysis. CONCLUSION: Our present study showed that follicular blood flow was positively associated with outcome of pregnancy as well as size of follicles, follicular fluid VEGF, but NO had no correlation with patient's age and pregnancy outcome. These results suggest that follicular blood flow might be a more effective prognostic marker of the pregnancy outcome of in vitro fertilization rather than follicular fluid VEGF and NO concentrations.

PURPOSE: To identify MR predictors of bone cement leakage in patients receiving percutaneous vertebroplasty. MATERIALS AND METHODS: Percutaneous vertebroplasties were performed in 45 vertebras (T7; one, T8; two, T10; two, T11; two, T12; eight, L1; fifteen, L2; eight, L3; five, L4; two) in 35 patients (age 52-83). The procedure was performed using an 11 G Jamshidi needle, which was inserted into the target by the bipedicular approach. Kyphoplasty, unilateral pedicular approach and extrapedicular approach cases were excluded. Shortly after the procedure, all patients underwent a noncontrast CT covering the vertebroplasty sites. A retrospective study was performed to determine whether cement leakage is related to any of following MR findings: presence of cortical disruption of the vertebral body, severity of body compression (proportion of abnormal to normal vertebral body volumes), bone cement amount, bone cement amount/severity of body compression ratio, proportion of low-signal area in a vertebral body on T1 weighted image, presence of either vacuum or cystic portion below a linear dark signal in a fractured vertebra, and the location of dark signal intensity line in a vertebral body. Logistic discrimination model stepwise method was used in the statistical analysis. RESULTS: On post-vertebroplasty CT scan, bone cement leakage was detected in or around 29 vertebrae (64%), including 11 vertebrae (24%) where leakage was found in the epidural space or radial vein. No patients displayed any neurological symptoms or signs. The most frequent site of bone cement leakage was the anterior external vertebral venous plexus (49%). Endplate cortical bone disruption was related to an increased risk of intervertebral bone cement leakage (p<0.05). Bone cement leakage tended to occur less frequently when there is a vacuum or cystic change below the dark linear signal intensity in a fractured vertebra (p<0.05). No other MR findings showed a statistically significant correlation with bone cement leakage. CONCLUSION: On pre-vertebroplasty MR imaging, vertebral endplate cortical bone disruption and vacuum or cystic change below dark linear signal intensity in fractured vertebra showed a significant correlation with bone cement leakage.
