The congenital dislocation of the hip is one of the most common congenital disease in the field of the orthopedic surgery. For the normal development of the acetabulum and femoral head, the displaced femoral head shouid be replaced in the acetabular socket as early as possible. In most cases treated in proper time, closed reduction is successful. If not, operative correction will almost always be necessary due to abnormal changes of the acetabulum and femoral head. We experienced 33 cases in 32 patients of the congenital dislocation of the hip at the Department of Orthopedic Surgery of Hanyang University Hospital from May, 1972 to December, 1980. The results obtained were as follows: 1. The most common aged group at the first visit was ranged from 12 months to 24 months and the preponderance of girl to boy was 3.6:1. 2. The ratio of left to right side was 1.6:1. 3. In delivery history, there were 3 cases of breech presentation, 1 case of Cesarean section and 1 case of prematurity. The associated congenital anomaly was observed in a case of which combined internal tibial torsion and talipes metatarsus varus deformity. 4. In 33 cases in 32 patients, 22 cases were treated conservatively and 11 cases were treated surgically. The results of treatment were excellent in 21 cases, good in 11 cases and fair in 11 case. We experienced 4 cases of neglected congenital dislocation of the hip in the period of late childhood, 3 cases were treated with Chiari osteotomy and the other 1 case was treated with Colonna capsular arthroplasty. The overall results were excellent.

PURPOSE: Successful management of epileptic patients requires complete control of seizures without adverse effect. The purpose of this study is to evaluate the hematologic effect and hepatic enzyme change of antiepileptic drugs in epileptic children and compare the changes of these values according to serum drug level. METHODS: The study included 89 epileptic children with antiepileptic drugs such as phenobarbital, valproate, and carbamazepine from May 1990 to July 1999. We classified these patients into 3 groups according to the drug they had taken; group 1 : patients treated by phenobarbital, group 2 : valproate, group 3 : carbamazepine. Baseline screening tests before the start of therapy for all patients included complete blood count(CBC) and differential, platelet count, serum alanine aminotransferase(ALT), aspartate aminotransferase(AST). The tests wee repeated at follow-up visits in 2nd week, 4th week, 6th week, 12th month on the new drug. We compared their mean hematologic and liver enzyme values, which were examined before and after taken the medications, such as white blood cell counts(WBC), red blood cell(RBC), platelets, hemoglobin(Hgb), hamatocrit(Hct), mean corpuscular volume(MCA), mean corpuscular hemoglobin(MCH), mean corpuscular hemoglobin concentration(MCHC), AST, and ALT. Statistically significant change of each value was observed according to drug blood levels. RESULTS: No significant differences were found between before and after medication on AST, ALT, Hgb, MCHC in all the groups. The WBC count diminished after medication of carbamazepine, significantly. But the correlation between WBC count and serum carbamazepine level was no statistically significant. The mean platelet count diminished significantly after medication of phenobarbital and valproate, and the correlation of maximum serum valproate level with the degree of platelets count was statistically significant. Statistically significant changes were found on MCV and MCH values before and after the medication in 3rd group. But it did not depend on carbamazepine blood level. CONCLUSION: Statistically significant correlations was found between the platelet count and the plasma valproate level. Significant increase of MCV and MCH, and decrease WBC count was observed after the medication of carbamazepine.

BACKGROUND: Outbreaks of multidrug-resistant tuberculosis(MDR-TB) are caused by the low rate of treatment response due to limitation in number of available drugs and high rates of adverse drug side-effects. This study analysed the risk factors for MDR-TB patients, who did not respond to treatment, with an aim to improve the rate of treatment response. METHODS: Retrospective study of 111 MDR-TB patients at National Mokpo Tuberculosis Hospital from Jan. 1996 to Dec. 1998 was made. The patients were separated into tow groups ; group I comprised of patients who were treated successfully and group II comprised of those were not treated successfully. In order to analyze the risk facotrs for treatment faulure, differences between the two groups were compared and the confidence limit regarding the results were tested using an independent t-test, chi-square test and a Fisher's exact tets. RESULTS: The treatment failure rate of MDO-TB patients was 32% (36 patients), and treatment success rate 68%(75 patients). This study found no significant difference between two groups in terms of age, sex, family history, extent of the disease on the chest X-ray, the number of sensitive drugs in the treatment regimen, and the number of sensitive bactericidal drugs in the treatement regimen (p>0.05). However, a past history of pulmonary tuberculosis, cavitary lesions on the chest X-ray, the number of tretaments, the number of resistant drugs and the number of drugs used showed a significant difference(p<0.05). CONCLUSION: The rate of treatment failure in MDR-TB was increased by a past history of pulmonary tuberculosis, cavitary lesions on the chest X-ray, the number of treatments, the number of resistant drugs and the number of drugs used. For improving the treatment response of MDR-TB, every effort should be made to reduce the drug resistance caused by failure of the first treatment.

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.

Treponema strain PFB4G is a novel oral spirochete and one of the most frequently detected organisms in subgingival plaque samples from rapidly progressive periodontitis and adult periodontitis patients. In this study, a genomic library of Treponema strain PFB4G was constructed in lambdaZAP expression vector. One positive clone that carried a 2.6-kb fragment was identified by screening with chicken Ig Y (immunoglobulin yolk) antibody raised against whole bacterial sonicates. Nucleotide sequencing of the subclones revealed an open reading frame (ORF) lacking the 5'-end. This region was obtained by PCR amplification using a degenerative and a specific primer. A complete open reading frame of 1,770 bp was identified and the deduced polypeptide consisted of 590 amino acids with a molecular mass of 65 kDa. The polypeptide, designated as OmpTL, had a typical prokaryotic signal sequence (19 amino acids) with a potential cleavage site for signal peptidase I and showed a significant level of homology with the outer membrane proteins of other oral treponemes, especially with that of Treponema maltophilum. The isolation of the gene encoding an outer membrane protein may allow the study of their roles in future, possibly as adhesion, pore forming or induction of proinflammatory cytokine synthesis.

Liver abscess in children is rare in developed countries; the incidence is 25 per 100,000 admissions in USA. Common complications are pleural effusion, empyema, pneumonitis, hepatopleural or hepatobronchial fistula, intraperitoneal or intrapericardiac rupture, septic shock, cerebral amebiasis, etc. These complications may lead to death if the management is delayed. However, recent management results in a mortality of less than 15%. We report a case of liver abscess in a child. He manifested with fever and abdominal pain in the right upper quadrant. On computerized tomography scans, multiple cystic lesions were seen in both lobes of the liver and were 5 to 55 mm in size. In laboratory findings, neutrophilic leukocytosis, peripheral eosinophila, elevated values of ESR, C-reactive protein, and elevated serum AST, ALT, ALP and GGT were detected. Furthermore, we determined the organisms in the blood culture and serum. Blood culture was positive for Streptococcus spp., and amebic indirect hemagglutination antibody titer was increased to 1:512.

Fourteen cases of bowenoid papulosis were studied both clinically and histologically and were compared with 22 cases of Bowen's disease to find histologic differences between the two diseases. Bowenoid papulosis was prevalent in young, sexually active adults, consisted of multiple erythematous or hyperpigmented papules, and located mostly on the penis and vulva. The main histologic characteristics of bowenoid papulosis were an orderly background of keratinocyte maturation of the epidermis with monotonous pattern, the frequent presence of 'skip area', and the lesser degree of cytologic atypia than seen in lesions of Bowen's disease. In addition, mitotic figures more than 5 per x400 filed, formation of keratin pearl, and spindling of keratinocytes, which have not been described in other articles yet, are considered very important findings for the diagnosis of bowenoid papulosis. It is our opinion that bowenoid papulosis can be reliably distinguished from Bowen's disease by light microscopic features. Paraffin-embedded samples of bowenoid papulosis, Bowen's disease, and normal skin were investigated with antibodies against S 100-protein to relate the number of intraepidermal Langerhans cells and the disease. Langerhans cells were found to be reduced when compared with normal skin. No significant differences between Bowen's disease and bowenoid papulosis were found in density of Langerhans cells.
