PURPOSE: This study was designed to evaluate usefulness of intravenous digital subtraction angiography (IV-DSA) in detection of peripheral arterial obstructive disease(PAOD) and in follow-up of percutaneous transluminal angioplasty(PTA). MATERIALS AND METHODS: 35 Patients who had clinical symptoms and signs of compromised lower extremity perfusion, was screened with IV-DSA and then performed confirmative conventional angiography. We obtained sensitivity, specificity and accuracy of IV-DSA by comparing the findings of IV-DSA with those of conventional angiography. 21 patients who had been performed successful PTA, were foliowed-up with IV-DSA in 3, 6, 12months. We studied patency rate and factors that influenced restenosis. RESULTS: The sensitivity, specificity and accuracy of IV-DSA were 100%, 97%, 97% in lilac artery, 92%, 96%, 93% in femoropopliteal artery, 85%, 75%, 70% in proximal tibioperoneal artery retrospectively. IV-DSA follow up after PTA showed patency rate of 67% in first 3month, 67% in 2nd 3month, 60% in next 6month. Longer length and more irregular surface of the stenotic site, and higher incidence of run-off of vessel and of residual stenosis in the patients with restenosis were noted. CONCLUSION: High sensitivity, specificity and accuracy of IV-DSA in evaluating PAOD suggest that IV-DSA is useful in screening, planning therapy and following up after PTA.

Since the first experimental nerve graft by Philipeaux and Vulpian in 1870, many successful graft have been reported by Bunnell, Boyes, Millesi, Sunderland and Seddon. Advances in microsurgery techniques prompted Millesi to introduce the concepts of interfascicular nerve grafting whereby groups of fascicles, and not whole nerve, are connected together. Hunt and Taylor described a free vasculized nerve graft with microvascular anastomoses and obtained rapid axonal advance and maturation of grafted nerve in a clinical case. It is true that a nerve graft should be inferior to an end-to-end nerve repair, because in the case of nerve grafting the axon have to cross two suture lines instead of one. On the other hand, nerve grafting is indicated whenever a significant gap is produced in a nerve as a result of injury. In a retrospective study of 46 patients, defect of the nerve with treated by nerve graft were analyzed from March, 1983 to January, 1993 and following results were obtained. 1. Nerve graft was useful method to repair nerve whenever a significant gap is produced in a nerve as a result of injury. 2. The sural nerve was used as a donor nerve and vasculized nerve graft can be useful. 3. Postoperative results of cases caused by electric burns were worse than others. 4. There were little significant value in the treatment results between epineural and perineural nerve graft. 5. Recovery of intrinsic function in median and ulnar nerve lesion above the elbow was poor and recovery of the intrinsic function in median nerve graft at the forearm level was better than level for lesion in the ulnar nerve at the same level.

Dengue fever is an important health problem for international travelers to all endemic areas. The steadily increasing numbers of tourists visiting endemic areas raise the risk of exposure, and imported dengue cases are increasingly observed in nonendemic area. Dengue has a wide spectrum of clinical presentations, often with unpredictable clinical evolution and outcome. While most patients recover following a self-limiting, non-severe clinical course, a small proportion progress to severe disease such as dengue hemorrhagic fever or dengue shock syndrome. Therefore, it is important to suspect dengue fever in every febrile patient returning from the tropics. Whenever it is suspected, a quick diagnosis and adequate managements are essential to avoid complications. We report two cases of imported dengue fever in Korean children presenting with fever, headache, nausea, and rash.

PURPOSE: The purpose of this study is to identify the national status of high risk infants who are being transferred at the neonatal intensive care units (NICU), and to analyze the differences in hospital facility resources and regions. METHODS: Survey was conducted in 81 of 117 hospital providing NICU in July of 2010. Data included information on number of NICU bed, resources in the NICU and birth place. RESULTS: Among the patients, 39% were transferred patients and 7.5% were transferred from other regions. In the comparison among the 6 regions, transfer rate was higher in Gyeongin, Chungcheong-Gangwon region and low in Jeolla and Jeju region. According to the multinominal logistic regression analysis, there were more transferred patients when the birth weight was heavier and hospital level and volume was higher. The relative risk ratio of transfer compared to Seoul area was 1.64 in Gyeongin region, 1.68 in Chungcheong-Gangwon region, and 0.63 in Jeolla region. When the each factor was adjusted, the higher number of transfers when there was heavier birth weight and higher level of hospital level and volume remained the same, but the differences among the regions, other than Gyeongin region, had disappeared. CONCLUSION: The transfer of high risk infants after their birth was usually being made for infants with heavier birth weight to hospitals with higher NICU level and volume, and differences among regions also existed. This kind of differences among regions is primarily due to the differences in the local NICU facilities.

Subungual exostosis are not uncommon, however, they are infrequently mentioned in the dermatologic literature. We report herein a rase of subungual exostosis in the great toe of 16-year-old female student which was confirmed by histopathologic and radiologic findings. Histopathologic examination showed that the mass was ooeered by a dense fibrous tissue which merged into a fibrocartilage cap and bone. Computed tomography showed a well defined, oval shaped, radiopacity of bony density capped by a radiolucency.

We report a case of congenital vellus hamartoma, which consists of numerous matured vellus hair follicles and sebaceous glands. This patient is 4-month-old male with multiple, variable sized nodules on the right epicanthsl fold area since birth. Histopathologically, some of the infundibular portion of the vellus hair shows irregular and reticulated hyperplasia. There are numerous well-formed vellus hair follicles surrounded with thick fibrous sheath and some of them are associated with rudiment sebaceous glands.

BACKGROUND: Patients without genuine zygapophysial joint pain exhibit a positive response to uncontrolled diagnostic blocks. We determined the false positive rate of single uncontrolled diagnostic zygapophysial joint block in patients with chronic back pain. METHOD: Thirty-five patients with chronic lower back pain were studied prospectively. All patients underwent a series of medial branch of dorsal rami blocks with lidocaine and bupivacaine starting at the symptomatic level to a maximum of three levels or until the pain was abolished. RESULTS: All patients proceeded with the injections. 16 patients (45%) had a definite or greater response to the initial lidocaine injection at one or more levels but only 5 (14%) had a 50% or greater response to a confirmatory injection of 0.5% bupivacaine. Using the confirmatory blocks as the criterion standard, the false positive rate of uncontrolled diagnostic blocks was 37% and the positive predictive value was only 31%. CONCLUSION: Uncontrolled diagnostic blocks may be unreliable for the diagnosis of lumbar zygapophysial joint pain.

PURPOSE: Nocturia and enuresis are common voiding problems in spinal cord injured patients despite a variety of management. The purpose of this study is to determine the efficacy of desmopressin, a synthetic analogue of antidiuretic mono, as an alternative treatment in the management of spinal cord injured(SCI) patients with neurogenic bladder dysfunction unresponsive to conventional therapy. MATERIALS AND METHODS: Fourteen SCI patients with nocturia or enuresis were included in this study. The patients received 10microgram desmopressin intranasally at bedtime once every 24 hours. RESULTS: There was a significant decrease in nocturnal urinary volume, frequency of nocturia and nocturnal enuresis during nighttime after desmopressin administration. Two patients stopped desmopressin because of side effects. 8 of 12 patients improved with desmopressin and the remainder had no effect. There was no serum abnormality, although there were side effects in three cases, such as gastro-intestinal trouble, chest discomfort or nasal congestion. CONCLUSIONS: Desmopressin is safe and effective in the management of nocturia or enuresis due to neurogenic bladder dysfunction in selected SCI patients.

From May, 1978 through Oct., 1979 the effect of Coenzyme Q10 was evaluated on 10 patients with chronic heart failure. The subjects selected for this study consisted of 7 patients with cardiomyopathy and 3 patients with valvular heart disease admitted to Severance Hospital, Yonsei University College of Medicine, All these patients had symptoms and signs of congestive heart failure which was stable for at least one month before starting Coenzyme Q10. Coenzyme Q10 was administered 30mg daily for eight weeks, one hour before meal and in combination with digitalis and/or diuretics. The drug effects were determined by measuring the cardio-thoracic ratio by chest X-ray, the sum of 'S' wave in V1 and 'R' wave in V5 in electrocardiogram, and PEP/LVET (pre-ejection period/left ventricular ejection time) by simultaneous tracings of carotid pulse and phonocardiogram every two weeks during medication. The cardio-thoracic ratio was improved in 4 of 10 cases, the sum of RV+SV5 was decreased in all 5 cases who showed voltages above 40mm before medication, and PEP/LVET ratio was decresed in 4 of 10 cases. The difference of average values before and after medication were not statistically significant(p<0.05) in all 3 parameters when examined by t-test. During treatment, there was improvement, if any, from two weeks after medication and no significant side effects were noted throughout the study period.
