The scimitar syndrome is a rare malfomation that can be defined as a partial or complete right pulmonary venous return into inferior vena cava immediately above or below the siaphragm. This malfomation is often associated with hypoplasia of right lung, anomalous arterial supply of the lower part of the lung, and cardiac dextroversion. We experienced a case of scimitar syndrome in a 15 years old girl and presenting the case with a brief review of the literature.

Intraosseous Neurilemmomas are very rare tumor and most of them are arose in the mandibular bone. A case report is made on the intraosseous neurilemmoma in the distal shaft of tibia which belong very rarely seen in the area of bone. The case was a 23 year old male who had multicystic lesion on the distal shaft of right tibia with marginal this sclerotic change on the radiological examination. The lesion of intraosseous neurilemmoma was confirmed by the microscopic examination after surgical treatment of curettage and bone graft. Also a review of literature on the neurilemmoma was made and reported.

u-Health based on ubiquitous information and communication network is being considered as an alternative to the mainstream face-to-face healthcare services in addition to its supportive functions. Traditional healthcare system has inherent problems such as limited accessibility and inadequate fulfillment of service needs to the underserved populations. Proponents of u-Health suggest that it will provide solutions to those problems. There have been many trials and pilot projects for telemedicine since 1988 in Korea, and the system is now called "u-Health". After legislation of clause regarding telehealth in the Korean medical law in 2002, local governments have made several attempts to utilize u-Health system to the patients with chronic disease living in rural under-served area. Recently, Korean government has implemented u-Health trial projects about tehemedicine, monitoring chronic disease, and providing homecare in the three underserved rural and many-islands area. Patients' perceived level of satisfaction, preference, attitude, and usability of u-Health was significantly high. Patient's compliance to u-Health has improved over time. A strategic approach based on the innovative and proactive mindset to the u-Health is strongly needed. At the time of u-Health implementation in the medically underserved area, utilization of both u-Health center and mobile clinic is recommended to achieve operational efficiency, and ensure high quality of service. Although u-Health is effective and supportive method to the mainstream face-to-face healthcare, we should be cautious, since u-Health model needs more development and more rigorous experiments.

Captopril tablets of two different producers were tested for bioequivalence as well as therapeutic equivalence. The pharmacokinetics, the time course of plasma angiotensin-converting enzyme inhibition, and the changes of systolic and diastolic blood pressure after administration of drugs were studied. In a balanced, randomized two-way crossover design, two single doses of 50mg each of captopril were administered orally to twelve male volunteers. Peak blood levels of free captopril were observed about 0.85 hour after the dose, and practically free captopril could not be detected in blood within 8 hours. Peak free captopril levels of both compounds were almost identical(Capoten(R), 464.3ng/ml ; Capril(R), 504.6ng/ml). No statistically significant difference was identified between two compounds when area und the concentration time curve, peak level, time to peak were compared. Inhibition of plasma angiotensin-converting enzyme to blood free captopril concentration showed the hyperbolic concentration-response relationship with IC50 value of 7.4ng/ml. The area under the percent angiotensin-converting enzyme inhibition versus time curve were quite similar after administration of both drugs. The compounds were also found to be equivalent on the premise that no significant difference was detected when the time courses of systolic and diastolic blood pressure reduction were compared.

This study aimed to determine factors that influence blood flow through coronary bypass grafts and to analyze relationship between the graft flow and postoperative outcome. Blood flow through 146 bypass grafts(GBF) was measured with transit-time ultrasound flowmeter during coronary artery bypass grafting operations in 50 patients. Single and multiple regression analyses were done for relationships between the GBF and four variables: internal diameter of recipient coronary artery, myocardial value of bypassed branch(es), type of graft, and finding of preoperative myocardial perfusion scan. The relationship between GBF and postoperative scan finding was also analyzed. 1. The mean GBF was significantly higher in sequential grafts than in single vein grafts or in internal thoracic artery grafts(61.5 vs. 46.9 and 42.5 ml/min). 2. Myocardial value and recipient artery diameter were found to be the factors determining GBF. There was no correlation between GBF and presence of perfusion defect in the preoperative scan. 3. Myocardial value was found to be more important than recipient artery diameter in determinintg GBF. 4. Reversible perfusion defects were more frequently found in the areas supplied by grafts with low GBF. But this fact had only mild statistical significance. These results suggest that blood flow through a bypass graft is more determined by the size of its supplying myocardium than by the size of recipient artery. So, we can expect effective improvement in myocardial flow reserve after grafting of small(1~1.5mm) coronary arteries, if they supply substantial area of myocardium.

For the pharmacokinetic analysis of isoniazid transfer into CSF, steady-state isoniazid concentrations of plasma and CSF were measured in eleven tuberculous meningitis patients confirmed with findings of CSF and neuroimazing. Peak plasma levels (4.17-21.5 micrograms/mL) were achieved at 0.25 to 3 hours after multiple isoniazid dose (600 mg/day). Terminal half-life, total clearance (CI/F) and volume of distribution (Vd/F) were 1.42 +/- 0.41 hr, 0.47 +/- 0.22 L/kg/hr and 0.93 +/- 0.48 L/kg, respectively. Isoniazid concentrations in CSF collected intermittently were highest at 3 hr (Mean, 4.18 micrograms/mL) and were 0.54 +/- 0.21 micrograms/mL at 12 hrs after the last dose of isoniazid 10 mg/kg/day. CSF/plasma partitioning of isoniazid and equilibration rate were estimated using modified pharmacokinetic/pharmacodynamic model. Disposition rate constant from CSF to plasma and CSF/plasma partitioning ratio of isoniazid were estimated to be 0.39 h-1 and 1.17, respectively.

PURPOSE: Soft tissue reconstruction is essential for recovery of finger function and aesthetics in any traumatic defect. The authors applied a reverse homodigital artery island flap for soft tissue defect on distal part of digits. The aim of this study is to evaluate the efficacy of the procedure. MATERIALS AND METHODS: Seven cases of soft tissue defects of finger tip were included in this study. There were six male and one female, mean age was 43 years and mean follow-up period was 38 months. The length of flaps ranged from 2.0 to 2.5 cm and width ranged from 1.0 to 2.0 cm. Flap survival, postoperative complications were evaluated. RESULTS: All flaps survived without loss. Donor sites were repaired with primary closure in five cases and skin graft in two cases. None of the patients showed significant complications and their average finger motion was 255degrees in total active motion at the last follow-up. CONCLUSION: The authors suggest that the reverse homodigital artery island flap could be a versatile treatment option for the soft tissue defect on distal part of digits.

PURPOSE: Cortical bone thickness is one of the important factor in mini-implant stability. This study was performed to investigate the buccal cortical bone thickness at every interdental area as an aid in planning mini-implant placement. MATERIALS AND METHODS: Two-dimensional slices at every interdental area were selected from the cone-beam computed tomography scans of 20 patients in third decade. Buccal cortical bone thickness was measured at 2, 4, and 6 mm levels from the alveolar crest in the interdental bones of posterior regions of both jaws using the plot profile function of Ez3D2009trade mark (Vatech, Yongin, Korea). The results were analyzed using by Mann-Whitney test. RESULTS: Buccal cortical bone was thicker in the mandible than in the maxilla. The thickness increased with further distance from the alveolar crest in the maxilla and with coming from the posterior to anterior region in the mandible (p<0.01). The maximum CT value showed an increasing tendency with further distance from the alveolar crest and with coming from posterior to anterior region in both jaws. CONCLUSION: Interdental buccal cortical bone thickness varied in both jaws, however our study showed a distinct tendency. We expect that these results could be helpful for the selection and preparation of mini-implant sites.

Operative clipping after previous endovascular coiling in an aneurysm is a different problem from primary clipping procedure for neurosurgeons. With the increasing use of coil embolization, neurosurgeons will more and more face the similar situation. We report surgical clipping cases of intracranial aneurysm regrown after endovascular coiling. Three patients with a history of subarachnoid hemorrhage due to ruptured aneurysm underwent endovascular treatment (EVT) with detachable coils. The aneurysms were in the posterior communicating artery, the middle cerebral artery, and distal anterior cerebral artery (DACA). Two near-total occlusions and one partial occlusion were achieved by EVT. After several months, angiographic follow-up revealed regrowth of the aneurysm requiring surgical clipping. Here, we report three cases in which surgical clipping was more difficult than a usual clipping procedure performed several months after EVT, because of adhesion and coil bulging into the aneurysmal neck. The difficulty of the treatment of the residual aneurysm after coiling is discussed, as are the surgical complications and limitations of clipping.

Coronary artery fistula accounts for 0.27~0.4% of all congenital cardiac defects. In more than 50% of the cases, right coronary artery is involved. The fistula drains into the right heart in 92% of the cases. Left heart is the site of termination in only 8% of the cases, especially less left ventricle (3%). We experienced a case of right coronary artery to left ventricular fistula in a 3-year-old boy who was diagnosed incidentally and underwent ligation of fistula.
