Acute cerebral infarctions are rare in children, however, they can occur as a complication of a Mycoplasma pneumoniae (MP) infection due to direct invasion, vasculitis, or a hypercoagulable state. We report on the case of a 5-year-old boy who had an extensive stroke in multiple cerebrovascular territories 10 days after the diagnosis of MP infection. Based on the suspicion that the cerebral infarction was associated with a macrolide-resistant MP infection, the patient was treated with levofloxacin, methyl-prednisolone, intravenous immunoglobulin, and enoxaparin. Despite this medical management, cerebral vascular narrowing progressed and a decompressive craniectomy became necessary for the patient's survival. According to laboratory tests, brain magnetic resonance imaging, and clinical manifestations, the cerebral infarction in this case appeared to be due to the combined effects of hypercoagulability and cytokineinduced vascular inflammation.

9p Tetrasomy is rare chromosomal aberration that was described in approximately 30 previous patients in the world and this is the first described in Korea. Here we report a 3 month-old boy who was referred for genetic evaluation because of facial dysmorphism, such as wide fontanells, hypertelorism, bulbous nose, low set ears, cleft lip and palate. He had also psychomotor retardation and hypotonia. He was diagnosed as tetrasomy 9p syndrome by clinical feature and chromosomal study. Thereafter, increased growing of head size compared with body weight and height was observed and brain MRI shows hydrocephaly associated with remarkable hypertrophy of choroid plexus and mild Dandy Walker syndrome.

Cosmetic lateral canthoplasty, in which the size of the eye is increased by extending the palpebral fissure and decreasing the degree of the eye slant, has become a prevalent procedure for East Asians. However, it is not uncommon for there to be complications or unfavorable results after the surgery. With this in mind, the authors have designed a surgical method to reduce complications in cosmetic lateral canthoplasty by preserving the lateral canthal angle. We discuss here the anatomy required for surgery, the surgical methods, and methods for reducing complications during cosmetic lateral canthoplasty.

PURPOSE: Recurrent abdominal pain syndrome (RAPS) is not uncommon in school-aged children, but the etiology and pathogenesis are not understood well. But recent studies suggest that motility disorder makes up a majority of the pathogenesis. The aim of this study was to investigate gastric emptying time (GET) which is a method to evaluate gastrointestinal motility in patients with recurrent abdominal pain syndrome. METHODS: Radionuclide GET was investigated in 34 patients who visited the Department of Pediatrics, Pusan National University Hospital due to recurrent abdominal pain from January 1996 to June 1997. After 8 hours of fasting, the patient received two pieces of toast and a fried egg tagged with 2 mci of 99mTc albumin colloid and sequential counting was accomplished. We calculated the geometric mean of two counts measured from AP-PA scans and investigated 60 minutes of intragastric radionuclide retention rate. RESULTS: A total of 34 patients (12 boys, 22 girls, M : F=1 : 1.8) participated in this study. The age ranged from 5 to 12 years and the mean age was 8.8 years. Associated symptoms were headache (7 patients), nausea (7 patients), constipation (2 patients), vomiting (1 patient), and diarrhea (1 patient). Anti-Helicobacter pylori IgG Ab was positive in 4 cases. Endoscopic gastritis was found in 6 cases. The mean of 60 minutes of intragastric radionuclide retention rate was 72 +/- 17% and 27 cases (79%) were delayed significantly. CONCLUSION: The results of our study suggest that delayed gastric emptying time is a cause of abdominal pain in patients with recurrent abdominal pain syndrome.

We report 23 cases of silicone stents intubation for obstruction of lacrimal drainage system in 23 patients with tearing and mucopurulent material discharge from January 1985 to April 1988. The success rate of silicone stents intubation was 47.4% and the most common site of obstruction was nasolacrimal duct(56.5%). 30.3% of patients had complications related to silicone stents, conjunctivitis, punctal erosion etc. With these results, we consider that congenital dacryostenosis, partical and complete nasolacrimal duct obstruction is mainly indicated for silicone stents intubation and better results will be gained if be done with acryocystorhinostomy to prevent complications related to silicone stents.

PURPOSE: We compared estimates of ejection fraction (EF) determined by gated Tl-201 perfusion SPECT (g-TI-SPECT) with those by gated blood pool (GBP) scan. MATERIALS AND METHODS: Eighteen subjects underwent g-TI-SPECT and GBP scan. After reconstruction of g-TI-SPECT, we measured EF with Cedars software. The comparison of the EF with g-TI-SPECT and GHP scan was assessed by correlation analysis and Bland Altman plot. RESULTS: The estimates of EF were significantly different (p<0.05) with g-TI-SPECT (40%+/-14%) and GBP scan (43%+/-14%). There was an excellent correlation of EF between e-TI-SPECT and GBP scan (r=0.94, p<0.001). The mean difference of EF between GRP scan and g-TI- SPECT was +3.2%, Ninety-five percent limits of agreement were +9,8%. EF between g-TI-SPECT and GBP scan were in poor agreement. CONCLUSION: The estimates of EF by g-TI-SPECT was well correlated with those by GBP scan. However, EF of g-TI-SPECT doesn't agree with EF of GBP scan. EF of g-TI-SPECT cant be used interchangeably with EF of GBP scan.

Background: The normal references for acetabular parameters are important for the diagnosis of hip diseases and planning of total hip arthroplasty. There are wide interindividual differences in acetabular morphology in the normal population, and little is known about differences in acetabular morphology in the average South Korean population. The purpose of this study was to evaluate side and sex differences in acetabular morphology in the South Korean population. Methods: The acetabular parameters, including anteversion angle, abduction angle, center-edge angle, acetabular width and depth, and acetabular-head index, were measured on three-dimensional computed tomography images in 197 healthy Korean adults. Differences in acetabular parameters according to side and sex were evaluated. Results: The mean acetabular anteversion angle of men and women was 17.3° ± 5.2° and 20.1° ± 3.5°, respectively. The mean acetabular width of men and women was 61.5 ± 4.6 cm and 56.5 ± 4.0 cm, respectively. There were significant sex differences in acetabular anteversion angle (p = 0.001) and acetabular width (p = 0.036) when adjusted for age, body height, and weight. The mean acetabular width of the right side and the left side was 60.2 ± 5.2 cm and 57.8 ± 4.5 cm, respectively. There were significant side differences in acetabular width (p = 0.007) when adjusted for age, body height, weight, and sex. Conclusions Differences and reference ranges of acetabular parameters are important for the diagnosis of acetabular deformity, such as femoroacetabular impingement and acetabular dysplasia. Moreover, these differences and reference ranges are useful for preoperative planning and safe positioning of acetabular components in total hip arthroplasty.

PURPOSE: This study was to determine the incidence and severity of venous irriation in patients receiving vinorelbine tartrate (Navelbine ) in combination chemotherapy. MATERIAL AND METHODS: Twenty four patients histologically confirmed non-small cell lung cancer were enrolled in this study who receiving vinorelbine in combination chemotherapy through a peripheral vein from Oct. 1997 to Mar. 1999 with retrospective study design method. One group was 6~10 minutes infusion rate, the other was 10~20 minutes infusion rate with the same free-flow intravenous infusion. RESULTS: A total of 126 infusions were observed in this study. Sixty-two infusions were admi nistered at the 6~10 minutes, and 64 infusions were administered at the 10~20 minutes. The incidence of any venous irritation was 3.2% (2/62) in the group that received the infusion in 6~10 minutes and 10.9% (7/64) in 10~20 minutes (p=0.164), so we could not acquire any statistical significance. However the incidence of severe venous irritation (grade 3, 4) was 0% (0/62) in 6~10 minutes infusion group and 9.4% (6/64) in 10~20 minutes infusion group. There was a significant difference between two groups (p=0.028) CONCLUSION: Our results suggest that venous irritation associated with vinorelbine tartrate infusion can be reduced by shorter duration of administration and vinorelbine tartrate might be recom mended to administer at 6~10 minutes infusion in clinical practice.

PURPOSE: Intractable diarrhea during infancy is one of the major causes of infant mortality. But, its etiology, clinical courses, or methods of treatment are not well known. Therefore, we conducted a clinical approach to intractable diarrhea during infancy. METHODS: We have retrospectively evaluated clinical characteristics, laboratory findings, methods of treatment, days required for recovery, in 23 infants who were admitted with intractable diarrhea, from January 1993 to December 1996. RESULTS: The onset age was 18.4 +/- 17.8 days and the duration of diarrhea was 28.8 +/- 16.5 days. All patients were fed artificial milk before the onset of diarrhea. The possible causes of diarrhea were infection (60.8%), change of milk, milk concentration (17.4%), or an unknown origin (21.8%). Laboratory findings on admission showed hemoglobin 9.5 +/- 2.2g/dL, serum albumin 2.9 +/- 0.7g/dL. E. coli was cultured in urine in 1 case. Stool rotavirus antibody was positive in 1 case. Nineteen patients (82.6%) required total parenteral nutrition for 18.3 +/- 13.6 days and antibiotics were administered to 20 patients (86.9%). Twenty-two patients (95.7%) were fed special element formula milk. All but one who died of necrotizing enterocolitis, recovered. Special element fomula milk was used for 92.6 +/- 20.5 days after discharge, and there were no cases of recurrence. CONCLUSION: We considered appropriate oral element fomulas, total parenteral nutrition and the proper treatment of infection as important factors in future outcome of intractable diarrhea during infancy. We thought the short-term administration of special formula milk can be substituted for normal milk or a weaning diet. However, encouraging breast feeding may perhaps be a more effective way of preventing this problem.
