Capitellar fracture was first described by Hahn in 1853. It is rare, espically in children, and has been occurred 0.5% to 1% of incidence of all elbow injuries. Factures of the capitellum can involve a significant portion of the articular surfaces. It is desirable to reduce and internally fix the capitellar fragment, if possible, because this restores the artucular surface and augment joint stability. Three patients with displaced fractures of the capitellum(capitulum humeri) were treated by open reduction and internal fixation using Herbert screws, which stabilized the joint, allowed anatomical reduction, and gave rigid fixation. Postoperatively, early motion of the joint was allowed. All fractures were united without evidence of avascular necrosis and final follow-up was excellent.

Trichorrhexis nodosa(TN) denotes small node-like swelling with a loss of cuticle of the hair shaft through which the hair readily fractures. The basic cause of TN is mechanical or chemical trauma, and a contributing factor is an inherent weakness of the hair shaft. We report a case of localized TN in a 37-year-old male. He had an ovoid hair patch with multiple small white-gray dotted and stubby hairs localized to the right occipital scalp. TN is known to be the commonest of all hair shaft anomalies (Price, 1975). However TN is rarely reported, and there have been only four reports in Korean dermatological literature, to our knowledge, which might be due to underdiagnosis of this disorder. We postulated that diagnostic difficulty lies in the discrepancy between terminology and gross morphological findings.

PURPOSE: We intended to evaluate the results of arthroscopic anterior cruciate ligament(ACL) reconstruction using Bone-achilles tendon-bone composite allograft by analyzing the results clinically and radiologically. MATERIALS AND METHODS: From May 1996 to June 1999, we followed 23 patients who had arthroscopic ACL reconstruction using bone-achilles tendon-bone composite allograft for minimum 24 months, and measured laxity using KT-2000 arthrometer, Lysholm score and enlargement of tibial tunnel width on plain radiograph. RESULTS: In KT-2000 arthrometer test, there was only side-to-side differences of 1.67 +/-0.7 mm between the involved and contralateral limb. Lysholm score was 61.7 +/-10.2 preoperatively and 89.3 +/-5.1 at the last follow up. And there was no tibial tunnel enlargement more than 5 mm at the last follow up. CONCLUSION: Arthroscopic ACL reconstruction using bone-achilles tendon-bone composite allograft has advantage of preservation of anatomic structure and secure bone-to-bone fixation like the bone-patel-lar tendon-bone graft that bone-achilles tendon-bone composite allograft is a reasonable choice in ACL reconstruction.

BACKGROUND: Immune tolerance induction (ITI) can reduce inhibitors against factor VIII concentrates by 70-80%. In this study, we elucidated the characteristics of inhibitors and attempted to determine the proper indications and timing for ITI. METHODS: Subjects included hemophilia A patients registered at the Korea Hemophilia Foundation from 1991 through 2014. Inhibitors were classified as persistent and transient. Patients were classified into groups according to peak inhibitor titer: low (<2 BU/mL), moderate (2 to <5 BU/mL), high (5 to <10 BU/mL), and very high titer (≥10 BU/mL). RESULTS: Overall, 350 (21.4%) of 1,634 hemophilia A patients developed inhibitors at least once. Of these, 100 (6.1%) and 250 (15.3%) patients developed persistent and transient inhibitors, respectively. For transient inhibitors, the median peak titer was 1.0 BU/mL, persistent for median of 11.0 months (10.0, 8.0, 13.0, and 19.0 months in the low, moderate, high, and very high titer transient inhibitor groups, respectively). Overall, 95.8% (215), 72.2% (17), 52.4% (21), and 21.7% (97) of patients in the low, moderate, high, and very high titer groups became inhibitor-negative spontaneously, without ITI. CONCLUSION: Given the spontaneous disappearance of inhibitors and high cost of ITI, it is worthwhile to postpone ITI for 11 months unless the peak inhibitor titer is greater than 10 BU/mL.

Midtrimester genetic amniocentesis has been a gold standard for prenatal diagnosis in antenatal care since last 25 years. After the triple serum marker test was introduced as a prenatal screening method for Down syndrome, the frequency of genetic amniocentesis was increased. OBJECTIVE: To determine the complication, risk of amniocentesis and detection rate of chromosomal abnormality. MATERIAL AND METHODS: A retrospective clinical analysis of 1,064 midtrimester genetic amnicentesis in IL Sin Christian Hospital antenatal clinic from Jan 1995 to Dec 1997. Chi square test was used for the statistical analysis and p value < 0.05 was considered significant. RESULTS: Amnicentesis were significantly increased in the age of 35-39 yrs and 40yrs over. And also the incidence of chromosomal abnormality was higher than younger age group. The indications of amnicentesis were screen positive of triple marker test(43%), advanced maternal age(20.8%), abnormal beta-hCG level, past history of chromosome abnormality or malformed baby and abnormal alpha-FP level in order. Total number of chromosomal abnormalities was 30 and the incidence of chromosomal abnormalities was 2.8%(30/1,064). The complications were developed in 13 cases and fetal loss rate was 0.78%(9/1,064). CONCLUSION: The detection rate of chromosomal abnormality in midtrimester amnicentesis for prenatal diagnosis was high and relatively safe procedure but, we should be attention to more careful manipulation.

BACKGROUND: Angiogenesis is crucial for many biological processes such as embryogenesis, cyclic changes in the endometrium and wound healing. It is also critical for the growth, invasion and metastasis of solid tumors. Vascular endothelial growth factor (VEGF) acts as a mitogen for endothelial cells and is expressed by the presence of various tumor cells. The objective of this study is to evaluate if angiogenesis is involved in the mouse skin carcinogenesis and if VEGF is related to angiogenesis. METHODS: We induced premalignant and malignant lesions on mouse (BALB/c) skin using the two stage chemical carcinogenesis moedl, DMBA (7,12-dimethylbenzanthracene) initiation and TPA (tetra decanoyl-phorbol-acetate) promotion. And we analysed the microvessel densities (MVD) and expression of VEGF in various stages of premalignant and malignant lesions by immunohistochemical studies. RESULTS: Squamous papillomas, keratoacanthoma, dermatofibroma, and squamous cell carcinomas were developed in 20 weeks. There were no differences in the incidence of benign and malignant tumors between 10-week and 20-week promotion groups. There were significant increases in MVD from normal and hyperplastic skin through premalignant lesion to invasive squamous cell carcinoma (p<0.0005). But the degree of VEGF expression neither correlated with neither MVD nor the tumor groups. CONCLUSIONS: Increased angiogenesis begins from the hyperplastic stage. VEGF produced by tumor cells may not play major roles in the angiogenesis in the two stage chemical carcinogenesis model of the mouse skin.

PURPOSE: Perinatal asphyxia occurring in newborn is one of the major causes of acute mortality and chronic neurological disability in survivors. We have studied the relationship between early electroencephalography(EEG) findings and clinical course and neurologic outcome in severe asphyxiated neonates. METHODS: Between the period of July 1999 and June 2002, 25 neonates who were diagnosed with severe perinatal asphyxia(1-minute Apgar score of < or =3 and initial pH is less than 7.2) at NICU in Dongsan Medical Center were enrolled. An EEG was recorded and analyzed within three days of life and divided into two groups - group 1(normal or focal change on EEG) and group 2(generalized abnormal EEG). Between the two groups, clinical courses and neurologic outcomes were compared. RESULTS: Fifteen infants(60%) were group 1 and ten infants(40%) were group 2(polyspikes, burst- suppression, generalized low voltage). Associated maternal disease, days of hospitalization, need for ventilator support, delay of oral feeding and convulsion duration are significantly higher and longer in group 2. Also, poor neurologic outcome(expire, developmental delay) was significantly higher in group 2(60%) than group 1(13.3%). CONCLUSION: Thus, the early neonatal EEG in asphyxiated newborn can be a predictable diagnostic tool in assessment of neurologic outcome.

PURPOSE: This study aimed to assess the prevalence of asthma, allergic rhinitis, and atopic dermatitis in elementary school students according to thebody mass index. METHODS: This study was conducted as cross-sectional descriptive research using a structured questionnaire. Data were collected from 6,398 students at 15 elementary schools located in Y City in Korea. The cross-sectional survey used the Korean version of International Study of Asthma and Allergies in Childhood questionnaire. Logistic regression analysis was performed to estimate the odds ratios of body mass index. RESULTS: The symptom prevalence of asthma, allergic rhinitis, and atopic dermatitis in the last 12 months was 12.4%, 49.5%, and 24.5%, respectively. The symptom prevalence of asthma was significantly higher in the obesity group. The number of those without any asthma symptom in lifetime was significantly smaller in the overweight (OR=0.70, p=.004) and obesity (OR=0.57, p=.005) groups than in the healthy weight group. CONCLUSION: These results suggest that asthma, allergic rhinitis, and atopic dermatitis prevention programs for elementary school students should include weight control intervention.
