PURPOSE: Beginning in the eighth week of fetal life the neuroblasts migrate from the midline to the periphery to form the gray matter of the cerebral cortex. Abnormalities of cell migration are characterized by ectopic location of neurons in the cerebral cortex. This broad group of anomalies include lissencephaly, schizencephaly, cortical dysplasia, gray matter heterotopia, and unilateral hemimegalencephaly. The purpose of this study was to correlate clinical data with anatomic data, which was evaluated by brain magnetic resonance imaging characteristics that are most useful in predicting clinical METHODS: The clinical records, EEG, and MRI findings of 20 patients with neuronal migration disorders were retrospectively reviewed. RESULTS: The 20 patients with neuronal migration disorders consisted of 11 with lissencephaly, 7 with cortical dysplasia, 2 with heterotopia, and 2 with schizencephaly. Clinically, seizure was the most common symptom in 85%, next developmental delay in 50%, and then delayed speech in 25%, motor deficit 15% in order. The main associated brain anomalies included absence of septum pellucidum in 20%, periventricular leukomalacia in 15%, and corpus callosal agenesis in 15% of Patients. Bilateral involvement of lesion in MRI was 60%, comparing to unilateral lesion in 40% of the patients. The most common involved lobes was frontoparietal region. An abnormality of EEG examination was showed in 11 cases of patients(68.7%). Patients with diffuse, bilateral lesion in MRI findings of neuronal migration disorders had significantly developmental delay than those with unilateral lesion(p=0.0007). Patients with unilateral lesion had significantly motor deficit than those with bilateral lesion(p=0.04). CONCLUSION: Seizures were the most common symptoms among neurological manifestations of neuronal migration disorders. Statistically significant correlations of delayed developement with bilateral lesion and motor deficit with unilateral lesion were found.

BACKGROUND: Although adults in 30s and 40s are at risk for hypertension management due to low rates of awareness, treatment, and control of hypertension, there has been a lack of study on hypertension management for this population. Thus, the purpose of this study is to examine blood pressure screening and other associated factors with hypertension management in terms of awareness, control, and treatment. METHODS: Secondary data analysis was performed on the data from the Fourth Korea National Health and Nutrition Examination Survey in 2007-2009. To examine whether blood pressure screening affects hypertension management in 929 subjects aged 30s and 40s with hypertension. Other factors, such as socio-demographics, health status, and health behaviors, were also included for data analysis. Chi-square test and multiple logistic regression analysis were carried out using SAS 9.1. RESULTS: Hypertension awareness rates were high in those who had diabetes mellitus (odds ratio [OR] 2.23; 95% confidence interval [CI] 1.27-3.90), self-rated their health status as poor (OR 2.89; 95% CI 1.82-4.58), and received a blood pressure check up (OR 5.96; 95% CI 2.90-12.25). Hypertension treatment rates were high in women (OR 2.50; 95% CI 1.47-4.27), and high in those who had diabetes mellitus (OR 2.59; 95% CI 1.49-4.47), self-rated their health status as poor (OR 2.53; 95% CI 1.54-4.14), self-reported as past smoker (OR 2.01; 95% CI 1.22-3.29), and received a blood pressure check up (OR 12.64; 95% CI 4.87-32.77). Hypertension control rates were high in women (OR 2.47; 95% CI 1.29-4.72), and high in those who self-reported as past smoker (OR 2.46; 95% CI 1.35-4.50), and received a blood pressure check up (OR 9.24; 95% CI 3.15-27.15). CONCLUSIONS: For effective hypertension management in 30s and 40s, we should encourage this population to have a regular blood pressure screening.

BACKGROUND: According to the 1992 version of ACLS guideline, adenosine is recommended as the first line drug far the treatment of paroxysmal supraventricular tachycardia(PSYT). But adenosine is not used frequently in our country, despite currency proven effect and safety. Therefore we tried to compare the efficacy and safety of adenosine with verapamil for the treatment far PSVT. MATERIALS AND METHODS: We prospectively reviewed charles of PSVT patients admitted to YongDong Severance Hospital from Jan. 1995 to Dec. 1996. These patients were randomly divided into two groups. The flat group was given 6mg of adenosine initially, and another 12mg was given within 5 minutes if fast dose failed. The other group was given 5mg of verapamil initially, and if failed, 10mg was given within 10 minutes. The results were analyzed by Chi-square test and student-t method. RESULTS: In converting PSVT to normal rhythm, adenosine and verapamil showed similar results and there was no difference between the two Groups in frequency of side elects, but serious arrhythmia such as ventricular fibrillation and ventricular tachycardia was not seen in the adenosine group. CONCLUSION: Adenosine not only showed comparable effect and safety, but also had shorter action time than verapamil. Therefore we recommand adenosine, as a safe and effective fort line drug for PSVT.

We report a rare case of adreno-hepatic fusion in a 63-year-old man with a traumatic hepatic rupture. The adrenal tissue was located beneath the Glisson's capsule of the liver, and measured 3.5x2x0.3 cm. On histologic examination, the ectopic tissue was composed of both adrenal cortex and medulla surrounded by a delicate capsule of connective tissue.

BACKGROUND: There are prerequisites for fungal nail infection: fungal organism, susceptible host, and environments with damaged nail. OBJECTIVE: The purpose of this study was to evaluate the growth rate of the great toe nail in distal subungual onychomycosis(DSO). MATERIALS AND METHODS:: The subjects are 60 adult patients with DSO and 19 age- and sex-matched controls with tinea pedis but no DSO. The growth rate of the great toe nail was measured. Data were evaluated with Mann-Whitney U-test and regression analysis using the statistical program for PC. RESULTS: The growth rate of the patients group showed a decrease against that of the controls. The equation for expected nail growth rate of specific age and sex was as follows: the expected nail growth rate(mm/day) = 0.07382 + (0.01498 × G) - (0.00033 × Age) - (0.00669 × S): if a person has DSO, G is 1, and if he has no DSO, G is 2; if a person is male, S is 1, and, female, 2. CONCLUSION: Patients with DSO often have a decreased growth rate of the nail compared with that of the controls. The authors propose the equation of expected nail growth rate in persons with or without DSO, and think that the growth rate of the nail is one of factors in the pathogenesis of onychomycosis.

Trichophyton tonsurans is a major causative agent of tinea capitis in the United States, Canada, Mezico and other Latin American countries, but the infection of T.tonsurans has not been reported in Korea. We report a case of tinea capitis caused by T. tonsurans in a 15-year-old student wrestler. He had a 3*3cm sized non-inflammatory alopecia with black dots on the right occipital area of the scalp. The diagnosis was established by a hght microscopic examination of the affected hairs and by mycological studies from cultures. To our knowledge, this is the first case in which T. tonsurans has been isolated in Korea, It is likely that the student acquired the infection through contact with a foreign wrestler during interaational games and practice. We should be concerned about the potential of spread of this infection in our country.

The computed tomography (CT) number is closely related to hematocrit level according to many of the previous reports. We measured the CT number in various organs, such as the frontal white matter, basal ganglia, occipital white matter, cerebrospinal fluid, liver, abdominal aorta, spleen, kidney, and psoas muscle. We correlated the CT numbers of the organs with hematocrit levels which were graded into 10% increments (20.0-29.9%, 30.0-39.9%, 40.0-49.9%). Thus the change of CT numbers in various organs according to the hematocrit level was analyzed. The increased CT numbers according to the 10% increment of hematocrit in the frontal white matter, basal ganglia, occipital white matter, liver, abdominal aorta, spleen, and psoas muscle were 1.3, 1.5, 1.6, 3.3, 5.3, 3.8, 2.4 respectively. Even though the CT numbers of the cerebrospinal fluid and kidney were not influenced by hematocrit level the CT numbers in most of the there organs postitively correlated with hematocrit level. Therefore, it was concluded that in the differential diagnosis using CT numbers, the hematocrit level of patient must be taken into consideration.
