To elucidate the clinical avaiability of FNAB, we reviewed retrospectively medical records of 30 patients who had infiltrative pulmonary lesion or pulmonary nodule or mediastinal mass, and got percutaneous fine needle aspiration biopsy using Westcott needle, 20~22 gauge, at the department of Pediatrics, Hanyang university hospital from July, 1986 to June, 1993. The obtained results were as follows: 1) There were 30 patients, aged 6 months to 15 years. 2) There were 17 male patients and 13 female patients with sex ratio of 1.3:1 3) Among 30 cases, we discovered 16 cases of infiltrative lesions, 7 cases of pulmonary nodules and 7 cases of mediastinal mass lesions. In mediastinal there were 4 cases of anterior mediastinum and 3 cases of posterior mediastinum. 4) Overall success rate on fine needle aspiration biopsy was 60% (18/30). The success rate was 50% (8/16) in infiltrative lesions, 50% (8/15) in pulmonary nodules and 71% (5/7) in mediastinal mass lesions, respectively. 5) Eight infiltrative lesione were diagnosed as Pneumocystis carinii pneumonia. Five pulmonary nodules were diagnosed as aspergillosis (2 cases), tuberculosis (1 case), mucormycosis (1 case), lung metastasis of metastasis of neuroblastoma (1 case). Five mediastinal mass lesions were diagnosed as teratoma (2 cases), lymphoma (1 case), malignant neurogenic tumor (1 case), ganglioneuroblastoma (1 case). 6) The complications occured in 20% (6 cases) among 30 procedures. All cases were due to pneumothorax: 3 cases spontaneously resolved, and 3 cases needed chest tube insertion. There were no death related with this procedures.

This study was designed to evaluate the therapeutic effect between single(A group) and five-day(B group) administration of IV gammaglobulin in the patients with Kawasaki disease from June 1987 to September 1993, who were admitted to the Department of Pediatrcs, Hanyang University College of Medicine. The clinical and echocardiographic results were as follows. 1) Of 90 cases, 40 cases belong to A group, and 50 cases to B group. The ratio of male to female was 2.60 : 1, and 85% of A group and 76% of B group was under the age of 3 years. 2) In 90% of A group and 88% of B group, peak level of platelet count was above 400,000.mm3, and as a whole peak level of platelet in 88.9% above 400,000/mm3. 3) Complications in S group were hepatitis(22.5%), coronary arterial involvement(12.5%), and gall bladder hydrops(7.5%), and in B group hepatitis(26%), gall bladder hydrops(18%), coronary arterial involvement(12%), pericardial effusion(4%), and meningitis(2%). 4) All 5 cases with mild coronary arterial dilatation in a group had improved in follow up echocardiography after 6 months. And in B group, 5 of 6 cases with coronary arterial involvement had improved, but coronary pathology in one case with large coronary aneurysm sustained after 2 years. In conclusion, we could not find the significant difference in reduction of the duration of illness or the coronary arterial disease between two groups, but we recommend single intravenous infusion of gammaglobulin as soon as possible to prevent severe coronary arterial disease.

OBJECTIVE: To evaluate factor XII deficiency in patients with recurrent spontaneous abortion and its relation to aPTT. MATERIAL AND METHOD: Factor XII was analyzed by clotting method. RESULTS: Of 70 patients with recurrent spontaneous abortion, there were 35 cases of factor XII deficiency. Among them, there were only 3 cases of prolonged aPTT. CONCLUSIONS: It is still unclear whether factor XII deficiency is related to recurrent spontaneous abortion. Molecular approaches should be used to understand further the causal relationship. But based on this result, in the workup of patients with recurrent spontaneous abortion, factor XII should be included. aPTT is not likely to represent the abnormality of factor XII.

PURPOSE: We wanted to determine the usefulness of computed tomography (CT) for patients with clinically-suspected but equivocal acute appendicitis, and we wanted to evaluate the differences of the sensitivity and specificity of CT according to the period of time from onset of the signs and symptoms to the performance of CT. METHODS: A retrospective study was done on 273 patients who visited our hospital for acute abdominal pain from Jan. 2003 to Dec. 2005, and they could not be excluded as suffering from acute appendicitis by their symptoms nor signs. RESULTS: Forty-three (15.8%) of the 273 patients did not undergo operation because their condition was not diagnosed as acute appendicitis and 190 patients were diagnosed as acute appendicitis by CT. The other 40 patients underwent diagnostic laparotomy because acute appendicitis could not be confirmed and any other diagnosis could not be made. The patients were classified into 6 groups according to the period of time from the onset of symptoms and signs to the performance of CT. The sensitivity of CT after 48 hours was statistically significantly increased as compared to performing CT before 48 hours (92.3% vs. 75.8%, respectively; P=0.023). CONCLUSION: Forty-three (15.8%) of the patients with clinically- suspected but equivocal acute appendicitis avoided unnecessary laparotomy by undergoing CT. The sensitivity was increased for diagnosing acute appendicitis by CT when it was performed after 48 hours from the onset of symptoms and signs, but caution may be needed during interpretation because of the false positives (2 patients;4.7%) could due to secondary change of other diseases

PURPOSE: Periventricular leukomalacia(PVL) is associated with various neurologic sequelae such as cerebral palsy and cortical blindness. The aim of this study was to analyse the correlation between the degree of PVL on MRI and clinical features or its severity. METHODS:Thirty-eight children with PVL on MRI among children brought to Pusan National University Hospital between January 1996 and August 1999 with development delay, cerebral palsy or epilepsy were included into the study group. We reviewed medical records of the patients including the gestational age, birth weight and neurologic sequelae. The grade for PVL was divided into 1 to 3, and it was based on abnormally increased signal intensity in periventricular white matter or a reduced amount of periventricular white matter or both, and compensatory focal ventricular enlargement. We analysed the relationship of the grade of PVL and various clinical findings. RESULTS: The age ranged from 11 months to 13 years old with a mean of 42 months. History of cesarean delivery and ventilator care were significantly frequent for the severe grade of PVL. Birth weight was significantly lower according to grade of PVL. Gestational age was lower according to the grade of PVL, but was not significant statistically. Incidence of cerebral palsy was significantly higher on the severe grade of PVL. Incidence of epilepsy and mental retardation were 34.2Yo and 23.9M, not associated with the grade of PVL. CONCLUSION: Incidence of cerebral palsy was associated with the severe grade of PVL, so we think MRI can be helpful in predicting neurodevelopmental outcome. (J Korean Pediatr Soc 2000;43 798-805)

To compare the effects of atracurium, 0.75 mg/kg, on the mean arterial pressures, heart rates and plasma histamine levels under 2%-enflurane inhalation with mask, 24 patients were allocated randomly into two groups; one(Group I, n=12) which atracurium was administered with rapid bolus injection for 5 seconds and the other(Group II, n=12) with the slow injection for 75 seconds. In both groups, there are the most significant decreases and the recovery in mean arterial pressure 1~2 min and 5 min after atracurium, respectively, Group I showed a significant decrease of mean arterial pressure about 10% more than Group II. In heart rate, there are the significant decreases gradually to 87~88% of control 5 min after atracurium in both graups except the only significant increase(104%) 1 min after atracurium in Group I. And Group I showed a significant increase(200%) in plasma histamine concentration (p< 0.05) 2 min after injection than before, but Group II did no significant change. In conclusion, the slow injection of atracurium over 75s during induction of anesthesia can attenuate the histamine-induced cardiovascular response.

This study was designed to investigate the ranges of pH, PaO2 PaCO2, and SaO2, before and during halothane-N2O-O2-pancuronium anesthesia under controlled ventilation (Vr: 500-600ml, f: 18-20/min). For the study, 25 surgical patients were selected with physical status ASA class l and ll and age ranging from 20 to 60 years. Samples of arterial and venous blood were collected before and during anesthesia, and sent for immediate gas analysis. The arterial blood gas samples before and during anesthesia revealed values within normal limits. After testing, we were able to control the blood gas patterns by ventilation to produce ideal conditions for patients undergoing anesthesia.
