In the classical ballet dancers, ankle joints are frequently overused. Especially the Pointe and the Releve are the two basic steps of ballet dance which cause the narrowing of the posterior aspect of the ankle joint. Posterior impingement syndrome of the ankle joint is defined as impingement occuring at the anatomical interval between the posterior tibial articular surface and os calcis. The purpose of this study is to describe the anatomy and etiology of this injury and to review the non-operative and operative treatments. Sixteen cases of posterior impingment syndrome had been treated between March 1994 and March 1995. Ten dancers were professional and six were students. The patients was divided 3groups by etiologic factor. Group 1 is anatomical problem factor, Group 2 is overuse factor and Group 3 is ankle sprain factor. Thirteen dancers (81.2%) improved with conservative treatment including local steroid injection. Among the other three dancers, operation was performed in one case. The other two cases stopped dancing. The result was good in one dancer after operation. In the classic ballet dancers, posrerior impingement syndrome was frequent disorder and major etiologic factors are anatomical problem and overuse. Operation was necessary in only group l. It is good result in conservative treatment and operation.

Miller-Dieter syndrome consists of severe type I lissencephaly, abnormal facial appearance, and sometimes other birth defects. Lissencephaly is a brain malformation manifested by a smooth cerebral surface, thickened cortical mantle, and microscopic evidence of incomplete neuronal migration. It comprises the agyria-pachygyria spectrum of malformation, thus excluding polymicrogyria and other cortical dysplasia. Type I lissencephaly results from abnormal migration between about 10 and 14 weeks gestaion. The brain is often small, and the ventricle is enlarged posteriorly The corpus callosum may be small or absent. The structural pattern of the cerebral hemispheres and ventricles is distintly immature, reminiscent of fetal brain. The superficial cellular layer resembles an immature cortex, with some separation into zones similar to layers III, V, and VI of normal cortex, although the cell population is decreased. In 1963 Miller described a malformation syndrome in a brother and sister with postnatal growth deficiency, craniofacial defects, and serious abnormalities of neurologic function. Autopsy at 3 and 4month of age, respectively, revealed lissencephaly. Subsequently, Dieker reported four additional patients with this disorder and referred to it as the 'lissencephaly syndrome'. We have experienced a case with this syndrome. Then we report this rare case with brief review of literature.

Clinical studies were made on 50 cases of chronic cough infants who were admitted to the department of Pediatrics of Kangnam St. Mary' s hospital from January, 1990 to July, 1991. The results were as follows; 1) The age distribution was from 3 months to 24 months old, and the most prevalent age group was 13~18months old. The male to female was 2.1:1. 2) The etiologic classification of the 50 cases were infantile asthma in 23 cases(46%), viral lower respiratory infection in 13 cases(26%), and infantile asthma associated with sinusitis in 5 cases(10%). 3) Cough was the most common clinical manifestation in all cases and followed by rhinorrhea, dyspnea, fever, and nasal stuffiness. Among physical findings, wheezing rales, and chest retraction were noted. 4) The duration of cough was 5 to 8 weeks in 26 cases(52%), 2 to weeks in 19 cases(38%), and above 9 weeks in 5 cases(10%). 5) 13 of 50 cases had a past allergic history and 8 of 50 cases had a family history of allergy. 6) In 50 cases, formula feeding was done in 28 cases(56%), breast feeing in 13 cases(26%), and mixed feeding in 9 cases(18%). 7) Eosinophilia was noted in 39.3% of infantile asthma and total IgE level above 100IUm/ml was noted in 60.7% of infantile asthma and in 18.2% of other diseases. 8) RAST results of infantile asthma showed that the positivity was 21.4% in house dust, 32.1% in Dermatophagoides pteronyssinus, 28.6% in Dermatophagoides farinae, 28.6% in egg white, 35.7% in milk. The ratio of positive RAST results were higher in infantile asthma than in other diseases. 9) Abnormal findings, including overinflation, infiltration, increased bronchovascular marking, and atelectasis, were noted in 42 cases(84%) on chest X-ray. In 7 cases, total opacification was noted on Waters' and Caldwell's view. In conclusion, chronic cough in infancy is best managed by determining the precise cause of the cough, then specificially treating the underlying disorder.

The clinicopathologic characteristics, treatments and prognosis of retinoblastoma, the most common intraocular tumor in children, were studied retrospectively in 101 cases(128eyes) who visited our clinic from 1987 to 1996. All patients were followed for 2 years or longer. Twenty seven cases were bilateral and seventy four cases were unilateral,. Eihgty four eyes were enucleated. Twenty one eyes were successfully treated by conservative modality. The rest refused any type of treatment. Orbital recurrence or distant metastasis were observed in 5 cases after enucleation without systemic treatment, and one died in spite of irradiation and aggressive chemotherapy. It is widely recognized that the prognosis for survival of retinoblastoma patients, especially unilateral, is excellent, however the authors emphasize the importance of careful postoperative histopathologic review and long term periodic follow-up to improve long-term prognosis.

PURPOSE: Febrile convulsion is a common clinical problem affecting 2-4 percent of children. The recurrence rate of FC is a approximately 33-50%. To identify factors influencing the recurrences of febrile convulsions, we investigated the risk factors, especially the relationship between the degree of pyrexia at the initial febrile seizure and the likelihood of subsequent febrile fits. METHODS: During the 24 months, we reviewed the children who presented their first febrile convulsion. All were admitted to the hospital for investigation and treatment. The study group compromised 136 children. A febrile convulsion was defined as a generalized convulsion that occurred within 15 minutes in a child aged 6 months to 5 years who had no pre-existing evidence of neurological abnormalities. The children were divided into three groups according to the severity of the fever recorded on presentation to hospital. Group I had temperatures higher than 39.5degrees C, group II, 38.5-39.4degrees C, and group III lower than 38.4degrees C. RESULTS: 1) 17 (40.5%) children had recurrences with a positive family history in first-degree relatives, 12 (60.0%) of febrile convulsions, 3 (42.9%) of epilepsy and 2 (66.7%) of febrile convulsions and epilepsy.2) In group I, three (15.8%) infants aged 6-18 months and two (13.3%) aged 19-30 months had recurrences of febrile convulsions. In group II, 13 (36.1%) infants aged 6-18 months and 5 (23.8%) aged 19-30 months had recurrences of febrile convulsions. In group III, 10 (41.7%) infants aged 6-18 months and 6 (46.2%) aged 19-30 months had recurrences of febrile convulsions.3) The overall recurrence after the initial febrile convulsion was 22 (52.4%) children by 6 months, 34 (81.0%) children by 12 months, 39 (92.9%) children by 18 months, and 42(100%) by 24 months.4) Fifteen (42.9%) had the recurrences between 6 and 12 months of age at initial febrile convulsion, 21(27.6%) between 13 and 24 months, and 4 (18.2%) between 25 and 36 months. CONCLUSION: Early age at onset of first febrile convulsion, a history of febrile convulsions in first-degree relatives were associated with an increased risk of recurrent febrile convulsions. Especially children with the lower degree of pyrexia at the time of the initial convulsion were more susceptible to recurrent convulsions than those with higher levels of pyrexia.

Chronic cough is a symptom frequently encountered by the pediatrician. Although most coughs are self-limited, chronic cough often proves to be a frustrating problem. This study was performed at Kangnam St. Mary's Hospital from January 1, 1992 to December 31, 1992, and 83 children with chronic cough persisting for longer than 3 weeks was evaluated. We categorized these patients into 5 age groups (1. Infant: uner 12 months of age, 2. Toddler: above age 1~below age 3, 3. Preschool: above age 3~below age 6,4. School: above age 6~below age 6~below age 12, 5. Adolecent: above age 12). The most common cause of chronic cough was the reactive airway disease (71.1%) such as asthma with or without sinusitis (56.6%) and bronchiolitis-reactive (14.5%). In infant age group, the most frequent causes of chronic cough were reactive airway disease(52.4%)such as bronchiolitis-reactive (28.6%) and infantile asthma (23.8%). The second and third common causes were congenital anomalies(23.8%) and bronchiolitis-nonreactive (23.8%). In toddler age, the most common cause was the reactive airway disease such as infantile asthma (10 cases: 50%) and bronchiolitis reactive (6cases; 30%) and congenital anomalies were the second common causes of chronic cough. In preschool, school and adolescent age group, asthma and sinusitis were the main causes of chronic cough. In the groups above age 3,73.2% of chronic cough were associated with sinusitis. Therefore, in the diagnostic and therapeutic approach of chronic cough, it should be considered that the cause of cough is either reactive airway disease with or without sinusitis or not. In infant and toddler age, congenital anomaly should be considered.

PURPOSE: In order to elucidate the actual mechanism and the optimal concentration of Lamotrigine(LTG) that suppresses epileptiform discharges, we observed epileptiform discharges from hippocampal slices of immature rat in 4-aminopyridine(4-AP) added Mg2+ - free medium of artificial cerebrospinal fluid(aCSF) with various LTG concentrations. METHODS: We divided 19-23 day-old Sprague-Dawley rats into 4 groups; control group(n=12) and 3 LTG groups depending on the concentrations of LTG such as 400 (n=9), 800(n=7), and 1,000(n=8) microM. The rats were anesthetized and their brains were taken, soaked in aCSF(NaCl 125 mM, KCl 2.5 mM, NaH2PO4 2 mM, MgSO4 1.25 mM NaHCO3 25 mM, CaCl2 2 mM, Glucose 10 mM, pH 7.3-7.4). And then the brains were cut into 400 microm hippocampal slices by a vibratome. The slices of control group were soaked in 200 microM 4-AP added Mg2+ -free medium of aCSF for 1 hour, and then extracellular recordings were performed in hippocampal CA1 pyramidal region. The slices of LTG groups were soaked in the solution containing 400, 800, and 1,000 microM LTG, then extracellular recordings were performed. RESULTS: Interictal discharges were observed in all the control and the LTG groups. The latency to the first interictal discharges after 4-AP addition was 52.7+/-26.9 sec in control group, but was 225.0+/-28.2 sec in 800 microM and 322.1+/-116.4 sec in 1,000 microM group of LTG(P<0.05). The duration of interictal discharges was 64.6+/-35.6 sec in control group, but was the shortest in 800 microM group of LTG at 39.3+/-12.6 sec. Ictal discharges were observed in all of control and 400 microM group, but the frequency was decreased as the concentration of LTG increases, 57.1% in 800 microM, 12.5% in 1,000 microM group. The latency to ictal discharge after 4-AP addition was 142.1+/-52.6 sec in control group, but increased as the concentration of LTG increases, 304.4+/-84.5 sec in 400 microM group and 689.8+/-213.1 sec in 800 microM group(P<0.05). The duration of ictal discharges was 1,534.7/-339.3 sec in control group, but decreased as the concentration of LTG increases, it was 126.5+/-76.1 sec in 800 microM group(P <0.05) and 42 sec in 1,000 microM group. CONCLUSION: The antiepileptic effects of LTG were most significant when the concentration, inhibiting epileptiform discharges induced by 4-AP and Mg2+ -free medium in hippocampal slices of immature rats, was 800 microM or higher. Although the basic pharmacologic mechanism of LTG is the inhibition of sodium channel, it may also work on potassium channel at higher concentrations.
