STUDY DESIGN: Sixteen patients with congenital kyphoscoliosis were evaluated the clinical and radiological results according to the treatment method. OBJECTIVES: To provide a guideline for surgical treatment of congenital kyphoscoliosis SUMMARY OF LITERATURE REVIEW: Congenital kyphoscoliosis is an abnormal coronal and sagittal curvature of spine that is caused by the presence of vertebral anomalies, which causes a significant deformity and disability. Correction of the deformity is challenging and accompanied by high risk of complications. Many methods of operative treatment were recommended with various results. MATERIALS & METHODS: We reviewed 16 patients of congenital kyphoscoliosis who were operated from 1984 to 1997, and follow-up periods were over 12 months in all. The average age of surgery was 12 years (ranged from 4 to 20 years). Nine cases were operated by excision of quadrant hemivertebra through combined anterior & posterior approach and 6 cases were treated only by posterior instrumentation and one underwent posterior on bloc spondylectomy. RESULTS: The type of curves were thoracic in 5, thoracolumbar in 9, lumbar area in 2 patients. Average angle of kyphosis was 55 degree preoperatively, 25 degree postoperatively, and 39 degree at the follow up study. Average angle of scoliosis was 48 degree, 22 degree, and 27 degree, respectively. In 9 cases corrected by excision of quadrant hemivertebra; kyphotic angle was changed from 62degrees preoperatively, to 22degrees postoperatively and to 36 degree at the end of follow up study, while scoliotic angle was changed from 47degrees, to 12degrees and to 21degrees, respectively. In 6 cases corrected by posterior instrumentation kyphotic angle was changed from 52degrees preoperatively, to 33degrees postoperatively and to 48degrees degree at the follow up study, while scoliotic angle was changed from 53degrees, to 33degrees and to 37degrees, respectively. CONCLUSION: Excision of quadrant hemivertebra through combined anterior and posterior approach or posterior instrumentation were resulted in significant loss of correction during the remaining growth period due to the secondary change of adjacent vertebrae. So, to obtain better correction and to reduce the recurrence of deformity, more aggressive approach including the concept of three dimentional osteotomy involving the upper and lower adjacent curve may be considered.

BACKGROUND: Catheterization of central vein may cause fetal complications such as cardiac arrhythmia, cardiac temponade, atrial perforation etc. For prevention of these complications, tip of central venous catheter should located in superior vena cava. The purpose of this study was to investigate the optimal positioning of central venous catheters. METHOD: From March 1996 to Jun 1996, a total of 50 patients who requiring central venous catheters were involved. First, we evaluate the accuracy of predetermined formula of 'Peres'. Second, we hypothesized that height of patients was correlated with optimal length of central venous catheters and we analysed relationship between height and optimal length of central venous catheters using simple regression analysis by SAS. RESULTS: 1) Predetermined formula of 'Peres' inaccurately predicted required length of central venous catheter. The accuracy was 78%. 2) There were a linear relationships between height and optimal length of central venous catheter. Their relationships was followed, Y=0.09X(Y: optimal length of central venous catheters, X: height, p=0.0001, R2=0.39). CONCLUSION: Using height of patients, we can accurately predict the optimal length of central venous catheters.

Kawasaki disease (KD) is an immune-mediated disease which is a leading cause of acquired cardiovascular disease in developed country. Recently, tumor necrosis factor-alpha (TNF-alpha) blocker, infliximab has been considered a promising option for patients with refractory KD. Although chronic use of a TNF-alpha blocker could increase risk of opportunistic infections, a few studies have documented that use of infliximab was safe without serious adverse effects in patients with KD. We observed serious bacterial infection after infliximab treatment in an infant with refractory KD. Our patient was a 5-month-old male infant diagnosed with KD who did not respond to repeated doses of intravenous immunoglobulin. We effectively treated him with a single infusion of infliximab (5 mg/kg), but gram-negative (Acinetobacter lwoffii) septicemia developed after infliximab infusion. Therefore, we report a case of serious septicemia after treatment with infliximab, and suggest considering the risk of severe infection when deciding whether to prescribe infliximab to an infant with refractory KD.

BACKGROUND: The number of patients of doxylamine overdose has increased, but there were little clinical reports. The purpose of this study is review the patients of doxylamine overdose for aid clinical decision making of patients disposition. METHODS: We reviewed medical records of patients who ingested doxylamine succinate retrospectively from Jan. 1, 1996 to Dec. 31. 1996. Data that was recorded were followed: age, sex, psychiatric history, amounts of ingestion, time interval from ingestion to arrival to hospital, initial vital signs and symptoms, EKG, chest PA, Lab. findings, treatment, patients disposition, length of hospital stay, complication. RESULTS : 1) Total number of patients was ninety and average dosage of ingestion was 1062mg. 2) Tachycardia was the most frequent anticholinergic symptom(46%). 3) Routine lab. findings was not abnormal except one patient who was diagnosed as Rhabdomyolysis. 4) Gut decontamination was performed in patients who had arrived at hospital in 2-3 hours, and who had ingested large dose of drug. 5) Five patients were admitted to Psychiatric dept. and one patient was admitted to emergency dept. for treatment of rhabdomyolysis. 6) The mean duration of hospital stay was 6.5 hours. CONCLUSION: The patients who ingested overdose of doxylamine was managed safely in emergency department, but we should warn against the possibility of rhabdomyolysis.

BACKGROUND: Tetanic spasm is often noted in hyperventilating patients coming in to emergency departments. Classical explanation far this phenomenon was decreased ionized calcium levels due to respiratory alkalosis precipitated by the hyperventilation. Clinically these symptoms were observed in hypocalcemia and were thought as such without doubt. But clinical investigation on the levels of ionized calcium levels have not been clarified. Recent investigations on hyperventilating volunteers have suggested other pathophysiology for tetanic spasm in hyperventilating patients which is the decrement of ionized magnesium level rather than ionized calcium. We wanted to see if these results applied to our hypeventilating patients and see if ionized magnesium level was a factor producing tetanic symptoms. METHOD AND MATERIAL : 35 patients with diagnosis of hyperventilation syndrome by emergency physician were studied retrospectively. Hyperventilating patients arriving at Severance hospital Emergency Center from Jan.1996 to Feb. 1998 were included. Patients with cardiovascular, pulmonary diseases, history of renal or liver disease were excluded. Ion-selective method was used to detect ionized calcium, magnesium levels and arterial blood gas features. Average levels were compared to reference ranges and Wilkoxon-rank. sum test was used to compare hyperventilating patients with tetanic spasm and those with other symptoms such as dyspnea, chest pain and palpitations. RESULTS: 1) Sodium, potassium and chloride levels were 138mmol/L, 3.6mmo1/L, 106mmol/L each which were within a normal range. 2) Degrees of hyperventilation were similar with average of PH 7.54(7.4-7.71), pCO2 23.6mmHg, showing respiratory alkalosis. 3) Ionized calcium and ionized magnesium each showed 0.61mg/dL, 0.16mg/dL lower values than the lowest reference ranges which were 4.5-5.6mg/dL for ionized calcium and 1.19-1.63 for ionized magnesium. 4) No statistical difference points were observed between the tetanic spasm group and group without spasm. Female preponderance were noted in tetanic spasm group. CONCLUSION: We conclude that ogler than decrement of ionized calcium, decrement of ionized magnesium could be a factor far inducing tetanic spasm in respiratory alkalosis caused by hyperventilation.

BACKGROUND: Do-Not-Resuscitate(DNR) order has been used without specific legislation commonly in hospitals of Korea. We designed this study to assess the current use of DNR order in the emergency department and to make a database for establishing a policy for DNR order, especially in ER. METHODS: We retrospectively reviewed medical records of 164 patients who expired in the emergency department of Severance hospital from Sep. 1996 to Aug. 1997. We evaluated age, sex, diagnosis, specific department involved, whether written orders were made and medical care after decision of DNR. The patients were divided into 2 groups : DNR vs CPR. To determine factors influencing DNR decision, we searched for presence of malignancy, irreversible shock, unconsciousness and chronic illness. The logistic regression analysis was used for statistical significance. RESULTS: We found that 102(62.2%) out of 164 expired patients had a DNR order. But only in 59% of cases, were written DNR order on the chart. Factors which had the most influence on decision of DNR were malignancy and age. The sex, chronic illness, irreversible shock, and unconsciousness were not significant factors. CONCLUSION: We found malignancy and old age as an important factor when DNR order had been made. But further evaluation of other factors may be necessary to establish definitely a policy for DNR order.

A case of xanthoma of the liver in a 61-year-old Korean woman with multiple myeloma, hyperlipidemia and xanthoma of the skin is described. Microscopically, the liver showed a multiple xanthomatous collection of foamy histiocytes as well as diffuse sinusoidal infiltration of the foam cells. This hepatic accumulation of foam cells seems to be related to hyperlipidemia of the patient. The mechanism of hyperlipidemia in multiple myeloma is discussed.
