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.

The “delta phalanx”, first named by BlundeII Jones in 1964, is a triangular(“delta-shaped”) or trapezoidal phalanx with C-shaped epiphyseal plate causing progressive angular deformity of the digit with growth. Neither splinting nor physical therapy is effective in improving the condition. Surgical correction is indicated and several methods of correction have been reported. Authors have experienced a rare case of “delta phalanx” occuring in the proximal phalanx of the syndactylous digit.

Fourty one cases of open fractures of tibial shaft complicated with varying degrees of soft tissue injuries were trested by one-plane unilateral external fixation with AO fixator. In seventeen csses among them, interfragmental lag screw fixation was applied in addition, for more rigidity and stability of the fixation. All of thern were followed up at least for one year and we obtained the following results. 1. Rigid stable external fixation provided by additional minimum internal fixation may not increase the rate of infection but rather enhance prompt primary bone healing. 2. One-plane unilatersl external fixation may facilitate good access to the wound for subsepuent reconstructive procedures, and enhance pain-free early full range of joint motion, thus promote early bone union. 3. Comparing with bilsteral fixation, there wss almost no difference in the union time of the fracture even with one-plsne unilatersl fixation.

We report a case of primary cardiac angiosarcoma in a 35 year-old woman. She presented with dyspnea, facial edema and neck vein distension during 1 month. The oval round large mass(8x4 cm) filling the right atrium infiltrated into the entire thickness of the lateral wall and extended to the vena cava and ventricle. The interatrial septum and pericardium seemed to be intact. Despite the surgical excision and adjuvant chemo-and radiotherapy, the patient died 8 months later due to tumor recurrence. The histologic findings of tumor varied from benign looking capillary proliferation mimicking granulation tissue to sarcoma composed of spindle cells. But anastomosing vascular channels lined by anaplastic polygonal cells and intracytoplasmic lumen containing red blood cells were characteristic findings. These tumor cells showed positive reaction to endothelial cell antigen and factor VIII-related antigen. The intercellular junctional complex and vascular channels formed by cytoplasmic process of tumor cells were identified by the ultrastructural study.

Radiological investigation in patients with clonorchiasis is very important as this is the only method of evaluating the severity of clonorchiasis. In order to correlate the radiologic and pathologic findings of clonorchiasis, fourteen rabbits infested with Clonorchis sinensis and five control rabbits were examined radiologically by ultrasonography, computed tomography and cholangiography and the results were correlated with pathologic findings. Dilatation of the intrahepatic small bile ducts of the liver was due to obstruction by flukes: oval or elliptical small filling defects or irregular margin of the bile ducts on cholangiogram or intraluminal echoes on sonogram represented flukes per se; periductal thickening on sonogram and periductal enhancement of bile ducts on CT were due to inflammatory cell infiltration, adenomatous hyperplasia and periductal fibrosis: band like enhancement at the periphery of the liver on CT represented proliferated bile ducts, destruction of liver cells and resultant fibrosis. The study confirmed the pathological bases for the radiological findings of clonorchiasis in liver and bile ducts and will, perhaps, serve as a basis for the future radiologic-pathological correlation of clonorchiasis and in further clinical and experimental researches in the biliary tract diseases.

BACKGROUND: Human growth hormone(hGH) plays a central role in linear bone growth and body metabolism. Its mitogenic effect in human tissues is mediated via direct and indirect actions. As proposed by the "somatomedin hypothesis", many circulating GH-mediated effects are exerted indirectly and systemically via stimulation of hepatic synthesis of insulin-like growth factor 1(IGF-1). Given additional evidences for the expression of growth hormone receptor(GH-R) and IGF-1 receptor(IGF-1R) on many target tissues including keratinocytes, melanocytes, and fibroblasts, it is now evident that the GH can act via systemic IGF-1 secreted by the liver and locally produced IGF-1, as well as directly through the GH receptor. OBJECTIVE: The purpose of this study was to investigate not only the effect of IGF-1 on the morphologic changes, proliferation, and melanization of cultured human melanocytes but also on its signal transduction pathway through the IGF-1R. METHODS: Melanocytes were exposed to IGF-1 at 10, 25, 50, 75, 100ng/ml and we examined the changes of cell morphology, number of cells, [3H]-thymidine incorporation, MTS assay, and melanization according to the concentrations and exposure times of IGF-1. Also, the activity of p44/42 MAPK/ERK according to the various exposure times of IGF-1(25ng/ml) was examined using the Western blotting method to find out about the signal transdution pathway of IGF-1. RESULTS: The results were as follows: 1. There were no significant morphological changes of cells between the control and experimental groups according to the concentrations and exposure times of IGF-1. 2. The effects on melanocytes according to the concentrations of IGF-1 5 days after adding IGF-1 : 1) The number of cells, [3H]-thymidine incorporation, and MTS assay were significantly higher than those of control group in all experimental groups(p<0.05). 2) The melanin content showed an insignificant decrease in all experimental groups. 3) The melanocytes responded independent of the IGF-1 concentration in the assay of cell number, [3H]-thymidine incorporation and MTS. 3. The effects on melanocytes according to the exposure times(3 days, 5 days, 7 days) of IGF-1(25 ng/ml) : 1) The number of cells, [3H]-thymidine incorporation, and MTS assay increased as time went by, and was significantly higher than those of control group at all exposure times(p<0.05). 2) The melanin content decreased after exposure of IGF-1, especially that of 3 days exposure group showed a significant decrease(p<0.05). 4. The activities of p44/42 MAPK/ERK increased suddenly at 5 minutes with a peak at 60 minutes and then abruptly decreased at 120 minutes after adding IGF-1 CONCLUSION: In summary, this study demonstrates that IGF-1 has no effect on the morphology, but it does increase the proliferation and slightly decrease the melanization of cultured human melanocytes. In addition, it is suggested that IGF-1 plays a role in regulation of proliferation of melanocytes via the receptor PTK pathway with activation of p44/42 MAPK/ERK.

This study was attempted to reveal the clinical and electroencephalographic findings in children who were experienced febrile convulsion and epilepsy. The subjects were 226 cases, under 15 years of age, who visited with convulsive disorders to the St. Mary's hospital between Jan. 1977 and Aug. 1978. Of these, 45 cases were febrile convulsion and 123 cases were epilepsies. The results were as follows : 1. The major cause of convulsions, in order of frequency, were epilepsy (54.4%), febrile convulsion (19.9%), meningitis and encephalitis (11.5%), cerebral palsy (4.0%), diarrhea (3.1%) and tetany (1.3%). 2. The leading cause of convulsions were different according to age : Before the age of 3, febrile convulsion, meningitis and encephalitis were common cause of convulsions and epilepsy was common after that age. 3. 68.8% of first febrile convulsion observed during the first 2 years of age. Male to female ratio was 3:2. 4. The EEG findings, of 24 cases with reccurent febrile convulsions, were normal in 29.9%, borderline in 8.3% and abnormal in 62.5% of them. The incidence of abnormal EEG findings were more frequent in the older children than in the younger ones : Of the 10 cases less than 3 years old, the chance of abnormal EEG findings was noted in 2 cases, compared to 13 cases of 14 cases more than 3 years old. This result suggest that the incidence of abnormal EEG in reccurent febrile convulsion seems to be correlated with the preexisting numbers of convulsive attacks. The findings of abnormal EEG were sporadic spike (40.0%), high voltage slow wave (20.0%), multiple spike (20.0%), slow wave dysrhythmia (13.3%) and spike and wave complex (6.7%). 5. The clinical type of epilepsies, in order of frequency, were grand mal (45.5%), minor motor seizure (17.1%), focal seizure (9.8%), petit mal absence (8.1%) and psychomotor seizure (4.9%). The major abnormal EEG finding in grand mal and focal seizure was asymmetric and focal slow wave, and it was found in 33.9% and 58.3% of their traces respectively. In psychomotor seizure, spike or sharp wave was noted in 66.7%, and in petit mal absence and minor seizure, spike and wave complex were noted 100.0% and 33.3% of them.
