PURPOSE: Epilepsy is generally defined as a chronic condition characterized by recurrent unprovoked seizure. It is still controversial whether the long-term antiepileptic drugs(AED) treatment will be necessary in children with first unprovoked seizure. Cognitive and behavioral side effects of AEDs are especially important in developing children. Therefore the rationale of AED treatment in the children with first unprovoked seizure depends upon the seizure recurrence rate and presence of risk factors related with seizure recurrence. We are going to evaluate the risk of seizure recurrence and risk factors after a first unprovoked seizure in children. METHODS: One hundred fifty eight patients presented with a first unprovoked seizure from July, 1994 to June, 1999 were prospectively followed by regular epilepsy clinic visit or telephone interview for a mean of 27 months. We analyzed overall recurrence risk and risk factors of seizure recurrence(EEG finding, etiology of seizure, seizure type, history of prior febrile convulsions, neurodevelopmental status prior to first seizure, presence of a Todd's paresis, family history of seizures, a seizure occuring while asleep, and duration of seizure) by Cox's proportional hazards model and Kaplan-Meier survival analysis. RESULTS: In 158 patients with first unprovoked seizure, 61 (39%) patients experienced subsequent seizure. The cumulative risk of seizure recurrence was 28.5, 37.6, and 42.3% at 6, 12, and 18 months. The median time to recurrence was 3 months, with 72% of recurrence occurring within 6 months, 92% within 1 year, and 100% within 2 years. On univariate analysis, risk factors for seizure recurrence included an etiology of seizure and abnormal EEG. In idiopathic cases, the risk factor was an EEG abnormality. CONCLUSION: Many of the children with a first unprovoked seizure will not have recurrences. The recurrence risk of a first unprovoked seizure in children have statistically correlated with the etiology of seizure(cryptogenic and symptomatic) and abnormal EEG. Children with an idiopathic first seizure and a normal EEG have a particularly favorable prognosis.

The uterine cervix is an uncommon site of primary non-Hodgkin's lymphoma (NHL). Although the cytologic findings of NHLs are well known, most cervicovaginal smear of uterine NHLs give lower diagnostic yield than common epithelial malignancy because abnormal cells do not appear in the sample in the absence of surface ulceration. Herein, we describe cytologic findings of a case of uterine cervical NHL which was initially diagnosed by cervicovaginal smear. The tumor cells were relatively uniform, isolated, large-sized with scanty cytoplasm and round or indented nuclei. The nuclei had stippled chromatin and small nucleoli. Histologically and immunohistochemically the tumor was proven to be large cell lymphoma of T-cell lineage.

PURPOSE: The purpose of this study was to standardize the somatosensory evoked potential (SEP) latency and amplitude of healthy preterm infants according to the postconceptional age. METHODS: The median nerve SEPs were recorded in 30 healthy preterm infants who were followed up until 6 months and were neurodevelopmentally normal. RESULTS: The mean peak latency and interpeak amplitude were following : P0=20.89+/-6.09 (msec), N1=26.32+/-5.18, P1=31.16+/-6.59, N2=36.52+/-7.22 : P0N1=1.07+/-0.72 (microvolt), N1P1= 1.56+/-0.93, P1N2=1.56+/-1.73. The N1 peak latency was inversely related to post- conceptional age. (P=0.036) : below 36 weeks=29.44+/-3.18 (msec), from 36 weeks to 37+6 weeks=27.72+/-5.47, from 38 weeks to 39+6 weeks=25.20+/-5.86, above 40 weeks=22.70+/-2.09. CONCLUSION: This study demonstrates normal ranges of SEP of median nerve in preterm infants as a basic data of neurodevelopmental prognostic assessment.

A rare case of traumatic bilateral anterior and posterior dislocstions of the hip wss occured by autamobile accident as a passenger injury. The right hip was dislocated anteroinferior to the righ scetabulum(neer the right obturator froamen), and the left hip was dislocated posterosuperior to the left acetsbulum with a ipsilateral femur head fracture caudsd to the fovea centralis(Fig. 1).

Vascular surgeons encounter a myriad of complications during the management of patients. The complications that occur associated with vascular surgery are often life threatening. Vascular surgeons have played a pioneering role in the development and introduction of new vascular and endovascular techniques, and some of the techniques changed the therapeutic options available for patients with vascular disease. Especially, with the development of endovascular surgery, there has been substantial change in the management of most vascular diseases and their complications. The best way to manage complications is to prevent them from occurring by careful planning, appropriate patient selection, extensive operator experience, and the correct use of appropriate devices. Successful operation outcomes depend on avoiding complications, as well as recognizing and promptly managing complications when they occur. This article reviews various local complications and their management in the field of vascular and endovascular surgery.

BACKGROUND: Congenital aortic stenosis in children is characterized by "excessive" left ventricular hypertrophy with reduced left ventricular systolic wall stress that allows for supernormal ejection performance. We hypothesized that left ventricular wall stress was decreased immediately after surgical correction of pure congenital aortic stenosis. Also measuring postoperative left ventricular wall stress was a useful noninvasive measurement that allowed direct assessment for oxygen consumption of myocardium than measuring the peak systolic pressure gradient between ascending aorta and left ventricle for the assessment of surgical results. MATERIAL AND METHOD: Between September 1993 and August 1999, 8 patients with isolated congenital aortic stenosis who underwent surgical correction at Yonsei cardiovascular center were evaluated. There were 6 male and 2 female patients ranging in age from 2 to 11 years(mean age, 10 years). Combined Hemodynamic-Ultrasonic method was used for studying left ventricular wall stress. We compared the wall stress peak systolic pressure gradient and ejection fraction preoperatively and postoperatively. RESULT: After surgical correction peak aortic gradient fell from 58.4+/-17.6, to 23.7+/-17.7 mmHg(p=0.018) and left ventricular ejection fraction decreased but it is not statistically significant. In the consideration of some factors that influence left ventricular end-systolic wall stress excluding one patient who underwent reoperation for restenosis of left ventricular outflow tract left ventricular end-systolic pressure and left ventricular end-systolic dimension were fell from 170.6+/-24.3 to 143.7+/-27.1 mmHg and from 1.78+/-0.4 to 1.76+/-0.4 cm respectively and left ventricular posterior wall thickness was increased from 1.10+/-0.2, to 1.27+/-0.3cm but it was not statistically singificant whereas left ventricular end-systolic wall stress fell from 79.2+/-24.9 to 57.1+/-27.6 kdynes/cm2(p=0.018) in 7 patients. For one patient who underwent reoperation peak aortic gradient fell from 83.0 to 59.7 mmHg whereas left ventricular end-systolic wall stress increased from 67.2 to 97.0 kdynes/cm2 The intervals did not change significnatly. CONCLUSION: We believe that probably some factors that are related to left ventricular geometry influenced the decreased left ventricular wall stress immediately after surgical correction of isolated congenital aortic stenosis. Left ventricular wall stress is a noninvasive measurement and can allow for more direct assesment than measuring peak aortic gradient particularly in consideration of the stress and oxygen consumption of the myocardium therefore we can conclude it is a useful measurement for postoperative assessment of congenital aortic stenosis.
