The 45 neonates with bronchopulmonary dysplasia among 355 neonates who were managed with mechanical ventilation and oxygen therapy in NICU of Seoul National University Chhildren's Hospital from January 1, 1968 to December 31, 1991, were analyzed for risk factors and outcome. The results were as follows: 1) The incidence of bronchopulmonary dysplasia was 12.7% 2) Respiratory Distress Syndrome was most common underlying problem. 3) The common radiologic findings of BPD were peripheral streaky density, emphysematous change, reticular or granular perihilar density, pulmonary interstitial emphysema, bubbly or small cystic change, and pneumothorax. 4) The survival rate of BPD showed 80% in the follow-up study. 5) Retinopathy of prematurity and intraventricular hemorrhage were more frequent significantly in the BPD group (p<0.05). 6) The risk factors of BPD were lower birth weight, shorter gestational age, longer duration of oxygen therapy an mechanical ventilation, and the presence of PDA.

OBJECTIVE: to determine the frequency of the multiple consecutive rib fracture after blunt chest trauma. DESIGN, MATERIALS, AND METHODS: We retrospectively reviewed all the radiographs and medical charts of 87 patients with rib fractures after blunt chest trauma. Rib fractures were divided into single aud multiple. The multiple rib fractures were subclassified as consecutive, interrupted continuous, or random. RESULTS: Thirteen cases of single and 83 cases of multiple rib fractures were present. Among the 83 cases of multiple fractures, there were 73 cases (88%) of consecutive fractures, 5 cases (6%) of interrupted continuous fractures and 5 cases (6%) of random fractures. CONCLUSION: Among the multiple rib fractures consecutive rib fractrues are much more common than noncontiguous rib fractures. We recommend that if one find an apparently nonfractured rib between contiguously fractured upper and lower ribs, one should meticulously search for possible fracture of an apparently normal rib with high-index of suspicion.

OBJECTIVES: Aseptic meningitis is a major cause of Korean childhood morbidity late spring and early summer. However, the nationwide incidences of the disease have not been reported. This study was conducted to evaluate the availability of National Health Insurance data (NHID) for the study of an epidemiological trend in the surveillance of aseptic meningitis in children. METHODS: All the claims, under A87, A87.8, and A87.9 by ICD-10, among children below 15 years of age, to the National Health Insurance Corporation, between January and December 1998, were extracted. A survey of the medical record of 3, 874 cases from 136 general hospitals was performed. The availability of the NHID was evaluated by the three following methods: 1) The diagnostic accuracy (the positive predictive value = proportion of the confirmed aseptic meningitis among the subjects registered as above disease-codes in NHID) was evaluated through a chart review, and according to age, gender, month and region of disease-occurrence. 2) The distribution of confirmed cases was compared with the distribution of total subjects from the NHID, for subjects in General hospitals, or the subjects surveyed. 3) The proportion of confirmed CSF test was confirmed, and the relating factor, which was the difference in CSF-test rate, analyzed. RESULTS: Among 3, 874 cases, CSF examinations were performed on 1, 845 (47.6%), and the CSF-test rates were different according to the medical utility (admission vs. OPD visit) and the severity of the symptoms and signs. The diagnostic accuracy for aseptic meningitis, and during the epidemic (May-Aug) and sporadic (Sept-Apr) periods, were 85.0 (1, 568/1, 845), 86.0 (1, 239/1, 440) and 81.2% (329/405), respectively. The distributions by age, sex, month or period (epidemic/sporadic) and region, in the confirmed cases, were similar to those in the NHID, in both the subjects at General hospitals and in those surveyed, to within +/-7%. CONCLUSIONS: In this paper, the NHID for the subjects registered with an aseptic meningitis disease-code might be available for an epidemiological study on the incidence-estimation of childhood aseptic meningitis, as the NHID could include both the probable and definite cases. On the basis of this result, further studies of time-series and secular trend analyses, using the NHID, will be performed.

Journal of the Korean Fracture Society 2005;18(4):443-451
PURPOSE: To present our operative experiences with carpometacarpal (CMC) injuries, excluding thumb. MATERIALS AND METHODS: Thirty four fracture and dislocations of CMC joint excluding thumb were reviewed retrospectively. Emphases were placed on injury mechanisms, anatomical location, times between diagnosis and surgery, treatment and complications. RESULTS: The average age of patients was 31.5 years. 19 cases of axial loading by blow as an injury mechanism. The 5th CMC joint was found to be the most frequently involved single joint (18 cases of 34 cases). Dorsal dislocation of CMC joints was present in 12 cases. Comminution of the carpal or metacarpal bone was present in 18 cases. The average time to surgery was 6 days. Twenty-seven cases were operated upon by closed reduction and percutaneous pinning. Seven cases were treated by open reduction and internal fixation. In the last follow up period, a clinically full hand function was restored in 31 cases. Intermittent pain was present in 6 cases in which there was grip weakness in 4 cases and limitation of motion in 3 cases. However, all cases were able to activities of daily living. CONCLUSION: We obtained good outcomes in CMC joint injuries through the accurate diagnosis and proper operative treatment.

PURPOSE: Peripheral arterial disease (PAD) is an increasing health problem, as we progress towards an aging society. The diseases known as risk factors of PAD are diabetes mellitus (DM), hypertension, and dyslipidemia, and PAD occurs consistently in patients with diabetes. The patients with PAD do not receive proper treatment at the proper moment, because PAD is almost asymptomatic, and most of the diagnosis is delayed. We aimed to determine the prevalence, risk factors and co-morbidities of PAD in patients who are managed for DM and hypertension in our referral center. METHODS: Patients with diabetes and hypertension were selected from the Gachon University Gil Hospital. Data of the patients, including demographics and presence of risk factors, were collected using an interviewer-administered questionnaire. For PAD of the low limbs, the ankle-brachial index (ABI) was used, and the PAD of low limbs was defined as <0.9 ABI. For carotid artery stenosis (CAS), carotid duplex ultrasound was analyzed, and CAS was defined as > or =50% internal CAS. RESULTS: Logistic regression analysis showed that old age (>70) and diabetes were independent risk factors of PAD. As the risk factor number increased, the prevalence of PAD became higher. CONCLUSION: The prevalence of PAD is continuously increasing. Old age and diabetes were independently associated with a high risk of all-cause PAD patients. For timely and proper management of PAD, large-scale research is needed. Based on research, we should make a detailed plan about early screening, and treatment of PAD.

PURPOSE: To analyze the results between PFN (Proximal Femoral Nail) and DHS (Dynamic Hip Screw) on the operative treatment of unstable intertrochanteric fractures retrospectively. MATERIALS AND METHODS: 35 cases of unstable intertrochanteric fractures (grouped 24 patients with DHS and 11 patients with PFN) who were taken the operations from Jan. 2001 to Mar. 2002 were analysed regarding to union state, union time, operation time, sliding length of lag screws, blood loss, postoperative complications and functional recovery scores by Sk?vron with ANOVA and multivariate linear regression. RESULTS: The means of union time were 17.9 weeks (DHS) and 17.0 weeks (PFN), sliding length of lag screws were 3.9 mm (DHS) and 2.1 mm (PFN), perioperative blood losses were 743 cc (DHS) and 736 cc (PFN), operation time were 93.4 minutes (DHS) and 102 minutes (PFN), and the functional recovery scores by Sk?vron were 71.8% (DHS) and 76.8% (PFN), respectively. The results of our study indicate that there were not statistically significant differences between PFN and DHS groups in treatment of unstable intertrochanteric fractures (p>0.05). But, there was less sliding of lag screws in PFN group in statistical significance (p<0.05). CONCLUSION: Authors think that PFN is one of the useful implants in treating unstable intertrochanteric fractures of the femur in regarding to sliding.

Purpose:
Patients who undergo radical surgery for rectal cancer often experience low anterior resection syndrome (LARS). Symptoms of this syndrome include frequent bowel movements, gas incontinence, fecal incontinence, fragmentation, and urgency. The aim of this study was to investigate the convergent validity, discriminative validity, and reliability of the Korean version of the LARS score questionnaire.
Methods:
The English LARS score questionnaire was translated into Korean using the forward-and-back translation method. A total of 146 patients who underwent radical surgery for rectal cancer answered the Korean version of the LARS score questionnaire including an anchor question assessing the impact of bowel function. Participants answered the questionnaire once more after 2 weeks.
Results:
The Korean LARS score questionnaire showed high convergent validity in terms of high correlation between the LARS score and quality of life (perfect fit 55.5% vs. moderate fit 37.6% vs. no fit 6.8%, respectively; P < 0.001). The LARS score also showed good discriminative validity between groups of patients differing by sex (29 for males vs. 25 for females; P = 0.014), tumor level (29 for ≤8 cm vs. 24 for >8 cm; P = 0.021), and radiotherapy (32 for yes vs. 24 for no; P = 0.001). The LARS score also demonstrated high reliability at test-retest with no difference between scores at the first and second tests (intraclass correlation coefficient: Q1 = 0.932; Q2 = 0.909, Q3 = 0.944, Q4 = 0.931, and Q5 = 0.942; P < 0.001, respectively).
Conclusion
The Korean version of the LARS score questionnaire has proven to be a valid and reliable tool for measuring LARS in Korean patients with rectal cancer.

PURPOSE: The purpose of this study was to assess the usefulness of multiplanar reconstruction (MPR) images in the preoperative evaluation of advanced gastric cancer. METHODS: Multidetector-row CT (MDCT) was performed on 61 patients with advanced gastric cancer, and the coronal and sagittal multiplanar images reconstructed from the transaxial data. The combined axial and MPR images were compared to the axial images alone to determine if the image quality and diagnostic accuracy had been improved. RESULTS: The observed image quality of the combined axial and MPR images, graded relative to the axial image alone, was fair in 22 (36.1%), good in 27 (44.2%), and excellent in 12 cases (19.7%). For the T staging, the diagnostic accuracy of combining the axial and MPR images (75.4%) was higher than that of the axial image alone (70.7%). However, there was no significant difference in the accuracies between the two methods (McNeamar test, P>0.05). For specific regions, the diagnostic accuracies of combining the axial and MPR images and the axial image alone were as follows: 90.2, and 73.8% with antral lesser curvature involvement; 93.4, and 75.4% with antral greater curvature involvement; 83.6, and 73.8% with gastric angle involvement; 96.7, and 88.5% with liver left lobe invasion; 90.2, and 83.6% with pancreas head invasion and 96.7, and 85.2% with colon or mesocolon invasion, respectively. CONCLUSION: Combining the axial and MPR images does not improve the depiction of the T staging compared to the axial image alone in advanced gastric cancer. However, combining the axial and MPR images improved the imaging quality and diagnostic accuracy of specific regions where the delineation of the conventional axial image was insufficient. Therefore, combining the axial and MPR images may be very useful in the preoperative evaluation of advanced gastric cancers.

Tuberous sclerosis is an autosomal dominant disorder characterized by facial skin lesions, epilepsy, and mental retardation. Pulmonary involvement in tuberous sclerosis is rare and shows characteristic reticulonodular infiltration and cystic changes. Lymphangioleiomyomatosis is characterized by the progressive proliferation of smooth muscle cells and occurs in 0.1-1% of patients with tuberous sclerosis. We encountered a case of pulmonary lymphangioleiomyomatosis associated with tuberous sclerosis and bilateral renal angiomyolipoma in a 31-year-old female patient. This case is reported here along with a brief review of the literature.
