Purpose: We designed this retrospective study to establish the incidence of diagnosic delay in children diagnosed with acute appendicitis and to identify associated factors with delayed diagnosis and its impact on the clinical course. Methods: All cases of children under 15 years of age who underwent appendectomy from 1996 to 2001 at Gangneung Asan Hospital were reviewed. We reviewed signs and symptoms, type of health professional first contacted, the advice given by the health professional and a history of appendicitis in first degree relatives. Diagnostic period is the time elapsed between first complaints and definitive diagnosis. Delay was defined as diagnostic period exceeded the 48 hours. Postoperative course and complications were also reviewed. Results: Incidence of diagnostic delay differed by whether diarrhea and fecalith on X-ray were present. Also children whose parents were advised to observe them at home were more likely to have a diagnostic delay. In almost half of the cases in delayed group, initial diagnosis was not acute appendicitis but gastroenteritis. The perforation rate in non-delayed group was 22%, whereas 87% in delayed group. The delayed group showed a higher number of postoperative complication and a longer hospitalization period. Conclusions: Diarrhea with abdominal pain and fever in children should not be dismissed as gastroenteritis, respiratory infections or other common disorders. Our study suggests that physicians have a responsibility to prevent diagnostic delay and resultant perforation of acute appendicitis in children by having a high index of suspicion about acute appendicitis.

Purpose : Kawasaki Disease(KD) is a febrile disease with acute multisystemic vasculitis which is seen commonly in early childhood. The cause and etiologic agents are still unknown to identify using ordinary bacterial and viral culture, but the clinical labaratory studies suggest that KD is one of autoimmune disorder caused by infectious agents, but that is not proved yet. The study was performed to investigate the IgG subclasses in acute stage of KB before treatment of IVIG(Intravenous immunoglobulin). Method : The 35 cases in acute stage of KD before treatment of IVIG who were hospitalized from jan. 1995 to dec. 1996. The obtained sera were measured level of total IgG, IgM, IgA, IgE and IgG subclasses IgGl, IgG2, IgG3, IgG4 by using EIA and SRID method. Results : 1) The sex ratio is male to female is 1.5: 1.0, and male is prone to infected. 2) Total IgG, IgM, IgA and IgE level is normal range with age adjusted, but few cases are shown slight high level of total IgG compare to normal range of age adjusted. 3) acute phage reactants such as CRP, C3, ESR are all increased in acute stage of cases. 4) IgG subclasses IgGl, IgG2, IgG3 are shown normal range of age adjusted, but remarkably low level of IgG4 in all of cases. Conclusions : The low level of IgG4 is able to increasing the incidence of KD, and may use early diagnostic tools combine with other clinical symptoms and signs. But the resulsts of reported studies are different to each other, so it needs more times and cases to get final evaluation of changes of serum immnunoglobulin levels correlate to increase the incidence of high risk group of KD patients.
Purpose : To identify clinical characteristics of severe respiratory syncytial virus (RSV) in neonatal period and early infancy and provide information in clinical practice. Methods : Twelve neonates and young infants (<6 months) who were infected by respiratory syncytial virus and required mechanical ventilation between March 2005 and July 2007 were enrolled. Diagnosis of RSV infection was made based on the positive results by rapid antigen immunoassay or polymerase chain reaction. Results : There were four premature infants, of whom three were near-term. Birth weight of subject patients was $2.8{\pm}0.6kg$, gestational age was $37{\pm}2weeks$ and the age at the time of admission was $35{\pm}15days$. Nine of them showed apnea and in five patients, apnea itself was an indication for mechanical ventilation. In seven of the apneic patients, apnea was the first manifestation of RSV infection. In three of these seven apneic patients, apnea preceded definite respiratory distress signs or typical stethoscopic findings by 1-3 days. Mean duration of mechanical ventilation was $3{\pm}2days$, and mean duration of stay in intensive care unit was $6{\pm}2days$. Conclusion : RSV is a major cause of severe respiratory tract infection in term or near-term infant younger than 2 months. For apnea could be the first manifestation of the RSV infection, high level of suspicion is required in practice of neonates or young infants who show any upper respiratory infection symptoms during RSV season.
Purpose: The purpose of this study was to evaluate the clinical and abdominal ultrasonogra- phic(US) features of spontaneously reduced transient small bowel intussusception in chlidren. Methods: We retrospectively reviewed the clinical and US findings of 98 children with intussusception who were admitted to the Pediatric Department of Ulsan Dong-Kang General Hospital from Mar. 1999 to Feb. 2000. Results: 1) Among 98 cases, there were 12 cases (12.3%) of transient small bowel intussusception(TSBI) and 86 cases (87.7%) of classic intussusception (CI). 2) The peak incidence of age in TSBI was over 3 years, which was older than that in CI. With regard to sex distribution, male predominated in both type. 3) Clinical symptoms and signs including cyclic irritability, vomiting, bloody stool, and abdominal mass in TSBI group were less common than those in CI group (41.7%, 33.4%, 0.0%, 0.0% vs 91.9%, 59.3%, 41.9%, 26.7%, respectively) but persistent abdominal pain was more common in TSBI group than in CI group (58.5% vs 11.2%). 4) The size of total target sign and surrounding peripheral hypoechoic rim of TSBI group on US were smaller than those of CI group ($11.95{\pm}2.61$ mm, $2.08{\pm}1.15$ mm vs $26.91{\pm}5.98$ mm, $7.86{\pm}2.77$ mm, respectively). 5) Concomittant illness was found more frequently in TSBI group than in CI group (66.7% vs 26.7%). 6) All case of TSBI group were reduced spontaneouly, which were confirmed by US, but none of CI group. Conclusion: Transient small bowel intussusception is probably more common than generally thought and its clinical and US findings is quite different from classical obstructing intussus-ception. Because all of our cases resulted in spontaneous reduction, we recommend careful observation and repeat examination rather than an immediate operation in transient small bowel intussusception.

Purpose : Premature narrowing of the foramen ovale is rare but serious clinical entity. Prenatal narrowing or obstruction of the foramen ovale shows symptoms such as right heart failure, fetal hydrops, triscupid regurgitation, left heart obstructive disease, and supraventricular tachycardia. This study aimed to assess the prenatal diagnosis and postnatal clinical course of restrictive foramen ovale in utero in otherwise normal heart. Methods : The subjects were five patients diagnosed with restrictive foramen ovale in utero from January 2001 to June 2005 at Chungnam National University Hospital. The diagnostic criteria was defined when the maximum diameter in a 4-chamber view is less than 2.5 mm and there is a continuous doppler velocity at the foramen ovale of more than 0.6m/s. Results : At the time of diagnosis of restrictive foramen ovale, gestation age was 34~37 wks, and chief complaints were fetal arrhythmia(2 cases), pericardial effusion, Ebstein anomaly and subaortic stenosis. Two cases which were diagnosed fetal hydrops and supraventricular tachycardia delivered by emergent cesarian section. Five cases were found to have right heart dilatation on echocardiogram after birth, but right heart dilatation became normalized at day 7 after birth and the clinical courses were not eventful. Conclusion : Identifying an obstructed foramen ovale in the fetus warrants the further search for additional cardiac and extracardiac anomalies, which may alter the prognosis. Delivery should be induced if possible in cases of foramen ovale obstruction with signs of cardiac decompensation.
Background : In case of tuberculous pneumonia, differentiation from bacterial lobar pneumonia is sometimes very difficult because clinical symptoms, signs and radiological images are very similar. So we investigated the usefulness of CA125, which is known to increase in tuberculous diseases, in differential diagnosis between tuberculous pneumonia (TBPN) and community acquired bacterial lobar pneumonia (LP). Methods : Serum CA125 level was measured in 20 patients with TBPN (female 12 male 8 : mean age 36.1 years) and 14 patients with LP (female 5 male 9 : mean age 45.1 years) by radioimmunoassay (Centocor(R) CA125 RIA kit). Results : 1) The serum CA125 level in TBPN ($333.7{\pm}283.5\;u/ml$) was higher than in LP ($60.9{\pm}66.2\;u/ml$). (P < 0.05) 2) If we took cut-off value as 195 u/ml in differential diagnosis between TBPN and LP, the sensitivity and specificity of CA125 level in the diagnosis of TBPN were 70% and 93%, respectively. 3) There was no significant difference in serum CA125 level between noncavitary TBPN ($242.1{\pm}76.6\;u/ml$, n=10) and cavitary TBPN ($399.6{\pm}318.4\;u/ml$, n=10). (P > 0.05) 4) Following up of serum CA125 level after initiation of antituberculosis treatment showed rapid decline and approach to near normal range in 6 months. Conclusion : High serum CA125 level (> 195 u/ml) was useful in differential diagnosis of TBPN from LP.
Purpose : To evaluate the usefulness of functional MRI (fMRI) of visual cortex in patients with ischemic infarction in the occipital lobe. Materials and Methods : Four patients with the symptoms and signs of visual cortical ischemia were included. Functional MRI was performed by 2D-FLASH technique with the parameter of 90/56msec TR/TE, $40^{\circ}$ flip angle, $240{\times}240{\;}FOV,{\;}64{\times}128$ matrix number, 8.32 seconds acquisition time, 8mm slice thickness. An axial slice including both visual cortices was selected and alternative activation and resting of the visual cortex was performed using red color photostimulator. all patients undertook visual field test, and vascular abnormality was examined by MRA (n=4) and DSA (n=2). fMRI results were compared with the results of a visual field test, conventional MRI and cerebral angiography. Results : On fMRI, decreased activity of the visual cortex was found in the occipital lobe corresponding to stenosis of the posterior cerebral artery or its branch noted on angiogram. However, 2 of 4 patients showed no abnormal findings on conventional MRI. Visual field defect was noted in 3 patients, one and of whom showed no abnormality on conventional MRI and diffusion-weighted image, but revealed decreased activity in the corresponding visual cortex on fMRI. Conclusion : fMRI may be a sensitive method for detection of the status of decreased blood flow or vascular reserve which other methods can not.
Purpose : The outbreaks of measles in infants and school children have been reported recently, but there are no specific treatment of these patients except symptomatic therapy. This study was performed to evaluate the effectiveness of intravenous gammaglobulin(IVGG) therapy in acute febrile phase of measles. Methods : The 68 cases in measles were treated with single dose of IVGG(400~500 mg/kg), and 44 cases were treated with only symptomatic treatment during the periods of 14 months from Jan. 2000 to Feb. 2001. They were compared to duration of fever, rash, the levels of CRP and days of admission on both groups after treatment. Results : The results obtained follows. The average of age was $7.9{\pm}3.6$ year old, and male to female was 1.0 : 1.6. The duration of fever after admission was $2.4{\pm}1.2$ days in treated group and $5.7{\pm}2.4$ days in control group. The period of disappearance of systemic erythematous maculopapular rash was $4.5{\pm}1.3$ days in treated group, and $6.9{\pm}2.4$ days in control group. The durations of admission day were also shown significantly shorter duration of period in treated group(P<0.05). The levels of CRP were no significant difference between two groups before treatment. However, treated group was significantly shown by improved within 5 days after IVGG therapy(P<0.05). Conclusions : The single dose of IVGG(400~500 mg/kg) therapy is one of rapid and effective therapy for clinical symptoms and signs in acute high febrile phase of measles.

Background : A pulmonary embolism often presents with nonspecific symptoms and signs. However, a delayed diagnosis can result in catastrophic outcome. The majority of preventable deaths associated with a pulmonary embolism can be ascribed to a missed diagnosis rather than to the failure of existing treatments. Therefore, accurate and rapid diagnostic methods are essential for the management of a pulmonary embolism. The recent generation of multidetector-row spiral CT scanners appears to outperform other imaging modalities in detecting a central and peripheral pulmonary embolism. However, there are some variations in the interpretations of the findings between observers. This study examined the inter-observer differences of the diagnoses in patients with a pulmonary embolism. Method : 64 patients who were diagnosed with a pulmonary embolism either clinically or with spiral chest CT from 2002 to 2004, were included. Two thoracic radiologists interpreted the multidetector-row spiral CT in terms of the diagnosis of a pulmonary embolism and the location of the thrombus independently. Among 64 patients, 14 patients were excluded because there was no evidence of a pulmonary embolism or there was different interpretation of the pulmonary embolism between radiologists. A clinical diagnosis was based on "Rules for predicting the probability of embolism". Results : The mean score of the patients according to the Wells method was $3.91{\pm}0.30$ (0-9). The accordance of the radiologists was 95% in the main, 85% in the lobar, 91.2% in the segmental, and 96% in the sub-segmental pulmonary arteries. After excluding the negative interpretation from both radiologists, their agreement was 76.2%(${\kappa}.$ 0.83) in the main, 57.6%(${\kappa}.$ 0.63) in the lobar, 51.5%(${\kappa}.$ 0.63) in the segmental, and 34.6%(${\kappa}.$ 0.49) in the sub-segmental pulmonary arteries. Conclusion : Chest CT has been recently applied to patients suspected of having a pulmonary embolism. It was found that spiral CT is a rapid test for diagnosing a thrombus, and there was reliable accordance between the observers from the area of the large pulmonary arteries. However, there was a lack of agreement between the observers in diagnosing thrombi located distal to the sub-segmental arteries.

Purpose: To study the long-term outcome of arthroscopic meniscectomy with regard to clinical symptoms and radiographic signs of osteoarthritic change. Materials and Methods: The materials for the investigation consisted of 79 individuals among 144 patients who underwent knee arthroscopy due to an isolated meniscal tear from October 1990 to September 1992 in our hospital. Those 79 individuals were followed up for $10{\sim}15$ years after the knee arthroscopy and were took clinical examination through the review of knee radiographies obtained with weight bearing. 52 of the 79 patients were men, and the mean age of the total materials was 34.6 years old (in the range $17{\sim}48$). Results: At follow-up, radiographic changes including Fairbank changes and joint space narrowing were seen from 45 of the 79 patients (56.2%). In other calculation, radiographic changes were seen in 23 out of 54 patients (42.6%) who had a partial meniscectomy, but were presented in 22 out of 25 patients (88.0%) who had a total meniscectomy. As a result, more radiographic changes were seen after total meniscectomy (p=0.03). In clinical results, 39 out of 54 patients (72.2%) after partial meniscectomy were satisfactory, and 14 out of 25 patients (56.0%) after total meniscectomy were satisfactory, therefore, more percentage of patients were satisfactory in partial meniscectomy group than in total meniscectomy group, but the statistical differences were absent (p=0.24). Conclusion: The frequency of radiographic changes in $10{\sim}15$ years after meniscectomy was related to the quantity of the meniscus removed, but the differences of these changes were low and had little influence on activity and knee function.
