Of 62 supracondylar fractures of the humerus in children treated for 10 years, 27 cases are described with follow-up study of 2 years and 6 months on average. These patients were treated percutaneous K-wires fixation after closed reduction. This method takes advantage in stability of fixation, vascular safety with any permissible any position of the elbow, early ambulation and short hospital stay, and low incidence of varus deformity in follow-up. Complication included transient ulnar sensory change, pin-tract infection and inaccurate position of K-wires. We observed 1 case of clinical cubitus varus among 17 cases during more than one-year follow-up and concluded this unhappy result was associated with imperfect initial reduction rather than growth disturbance or initial displacement.

Rigid posterior fixation of the atlas to the third and fourth cervical spine was achieved in a patient in whom axis pedicle fracture and dislocation of axis on the third cervical spine. Althouth there was no evidence of neurologic disorder, marked instability of axis on the third cervical spine should inevitably be fused in any procedures. An anatomically contoured loop was secured to the posterior arch of the atlas and the laminae of the third and the fourth cervical spine by sublaminar wirings. The technique has the advantage over bone graft, either alone or with cement, in that it affords rigid stabilization, allows early mobilization and some flexion movement of atlanto-occipital joint.

OBJECTIVE: TA retrospective study is performed on 28 patients with primary intraventricular hemorrhage(PIVH) to examine the outcome and prognostic factors associated with this disorder. METHODS: Clinical data collected between 1998 and 2002 was used in the present study. The outcomes of these patients were compared by age, etiology, initial Glasgow Coma Score(GCS), Graeb's score, ventriculocranial ratio(VCR), hemorrhagic dilation of the third ventricle, and hemorrhagic dilation of the fourth ventricle. The Glasgow Outcome Scale(GOS) at discharge was used for the comparison of outcomes. RESULTS: The mean age of these patients was 48.4+/-17.4 years. The underlying causes of PIVH were hypertension(53.6%), moyamoya disease(17.9%), arteriovenous malformation(10.7%), cerebral aneurysm(7.1%), and unknown(10.7%). The age and etiology were not correlated with outcome. Patients with a GCS of 13-15 showed a good outcome in 90.5%(p<0.05). Those with a higher VCR(> or =0.23) showed a poor outcome in 64.3%(p<0.05). Patients with a Graeb's score of 9-12 showed a poor outcome in 87.5%(p<0.05). Those with hemorrhagic dilatation of the third ventricle showed a poor outcome in 80.0%, and those with hemorrhagic dilatation of the fourth ventricle showed a poor outcome in 85.7%(p<0.05). The overall mortality rate was 17.9%. CONCLUSION: Low initial GCS, high Graeb's score, high VCR, and hemorrhagic dilatation of the third ventricle or the fourth ventricle are correlated with poor outcome in PIVH.

Microarray analysis was used to investigate the lack of identified mammalian target of rapamycin (mTOR) pathway downstream genes to overcome cross-talk at non-muscle invasive high-grade (HG)-urothelial carcinoma (UC) of the bladder, gene expression patterns, gene ontology, and gene clustering by triple (p70S6K, S6K, and eIF4E) small interfering RNAs (siRNAs) or rapamycin in 5637 and T24 cell lines. We selected mTOR pathway downstream genes that were suppressed by siRNAs more than 2-fold, or were up-regulated or down-regulated by rapamycin more than 2-fold. We validated mTOR downstream genes with immunohistochemistry using a tissue microarray (TMA) of 125 non-muscle invasive HG-UC patients and knockout study to evaluate the synergistic effect with rapamycin. The microarray analysis selected mTOR pathway downstream genes consisting of 4 rapamycin up-regulated genes (FABP4, H19, ANXA10, and UPK3A) and 4 rapamycin down-regulated genes (FOXD3, ATP7A, plexin D1, and ADAMTS5). In the TMA, FABP4, and ATP7A were more expressed at T1 and FOXD3 was at Ta. ANXA10 and ADAMTS5 were more expressed in tumors ≤ 3 cm in diameter. In a multivariate Cox regression model, ANXA10 was a significant predictor of recurrence and ATP7A was a significant predictor of progression in non-muscle invasive HG-UC of the bladder. In an ATP7A knock-out model, rapamycin treatment synergistically inhibited cell viability, wound healing, and invasion ability compared to rapamycin only. Activity of the ANXA10 and ATP7A mTOR pathway downstream genes might predict recurrence and progression in non-muscle invasive HG-UC of the bladder. ATP7A knockout overcomes rapamycin cross-talk.

OBJECTIVE: Although the detection of crossed cerebellar diaschisis (CCD) by means of different imaging modalities is well described, little is known about its diagnosis by computed tomography perfusion (CTP) imaging. We investigated the detection rate of CCD by CTP imaging and the factors related to CCD on CTP images in patients with acute ischemic stroke. MATERIALS AND METHODS: CT perfusion maps of cerebral blood volume (CBV), cerebral blood flow (CBF), mean transit time (MTT), and time-to-peak (TTP) obtained from 81 consecutive patients affected by an acute ischemic stroke were retrospectively reviewed. Whole-brain perfusion maps were obtained with a multichannel CT scanner using the toggling-table technique. The criteria for CCD was a unilateral supratentorial ischemic lesion and an accompanying decrease in perfusion of the contralateral cerebellar hemisphere on the basis of CTP maps by visual inspection without a set threshold. Maps were quantitatively analyzed in CCD positive cases. RESULTS: The criteria for CCD were fulfilled in 25 of the 81 cases (31%). Detection rates per CTP map were as follows: MTT (31%) > TTP (21%) > CBF (9%) > CBV (6%). Supratentorial ischemic volume, degree of perfusion reduction, and infratentorial asymmetry index correlated strongly (R, 0.555-0.870) and significantly (p < 0.05) with each other in CCD-positive cases. CONCLUSION: It is possible to detect CCD on all four of the CTP-based maps. Of these maps, MTT is most sensitive in detecting CCD. Our data indicate that CTP imaging is a valid tool for the diagnosis of CCD in patients affected by an acute hemispheric stroke.

PURPOSE: To assess the therapeutic effect of Novalis radiosurgery for metastatic spinal tumors and evaluate the changes after treatment using MR imaging. MATERIALS AND METHODS: Between November 2003 and June 2005, 21 patients with metastatic spinal tumors underwent Novalis radiosurgery. Of these patients, the 7 with 13 metastatic spinal tumors who had undergone follow-up MR imaging were included in this study. The tumor locations were cervical spine in three, thoracic spine in four, lumbar spine in five and sacrum in one. During the first three months after Novalis radiosurgery, follow-up MRI was performed monthly and subsequently at 3-6-month intervals. On MR imaging, the volume of the tumors, the changes of their signal intensities and any changes in adjacent spinal cord were evaluated. RESULTS: Among the 13 lesions, 9 were decreased in volume (69.2%), 2 were stable (15.4%) and 2 were slightly increased. Seven of 9 lesions showed decreased signal intensity on T2 weighted images and 4 had compressive deformity. Two of 9 lesions had increased T2 signal intensity and tumor necrosis were detected on contrast-enhanced MR imaging. No changes in spinal cord were noted in any of the lesions. Those changes were detected on MRI obtained 1 month after Novalis surgery and the lesion sizes were gradually changed up to 3 months. CONCLUSION: Novalis radiosurgery was effective for the treatment of metastatic spinal tumor and the suppression of tumor growth. The estimation of therapeutic effect and detecting complication were precisely evaluated on MR imaging.

OBJECTIVE: Our purpose was to estimate the prevalence of hepatitis C virus seropositivity and define the risk factors for HCV infection in a group of pregnant women and the effect of HCV infection to mother and baby at the time of delivery. METHODS: From March 1997 to February 1998, 5655 women who delivered over 20 gestational weeks at our hospital were screened for HCV-Antibody(RIA), and the samples of most of HCV-Ab positive cases were analyzed for HCV-RNA by polymerase chain reaction(PCR). We also studied the risk factors for HCV infection, the effect of HCV infection to mothers and neonates at delivery. RESULTS: Of 5655 mothers 25 (0.44%) were HCV-Ab positive, and 20 of HCV-Ab positive mothers were analyzed for HCV-RNA by PCR. Of 20 HCV-Ab positive mothers 12 cases (60%) were HCV-RNA positive. Risk factors significantly more prevalent among HCV-seropositive patients were : a history of habitual intraveneous drug use, a history of smoking, alcohol drinking during pregnancy, having liver cirrhorsis. The proportions who had received a blood transfusion, had a history or ongoing syphilis or were positive for hepatitis B virus surface antigen were not significantly different between seropositive and seronegative women. Liver function test at delivery was abnormal in 4 cases(16%) of HCV-Ab positive group. And the number of abnomal liver function test cases in HCV-Ab negative group were 47(0.83%). This had statistical difference. In neonates at delivery, all 20 neonates of 20 ones having HCV-Ab positive mother were HCV-Ab positive. But only 2 cases of 20 babies were HCV-RNA positive. CONCLUSION: Mothers who have risk factors such as injecting drug use, smoking, alchohol drinking and liver cirrhorsis, should undergo HCV-Ab testing and quantitative HCV-RNA testing by PCR. More advanced studies about vertical transmission of HCV infection are needed.

BACKGROUND: Onychomycosis, especially toenail onychomycosis has become one of the common fungal infection and has historically been regarded as a cosmetic rather than medical problem by many patients, even by physicians. Recently, however, there are several reports that this is a refractory disease which may cause a deleterious effect on patients' quality of life (QOL). OBJECTIVE: The purpose of this study was to investigate the impact of toenail onychomycosis on QOL in Korea and to assess the changes of QOL after treatment. METHODS: Total 1004 patients with toenail onychomycosis which was confirmed by clinical findings and KOH preparation were enrolled at 47 dermatologic centers in Korea, and interviewed with standardized QOL questionnaire before and after systemic antifungal treatment. Responses to the questionnaire were scored by f-point scale (0~4) and averaged, and were analyzed for 5 dimensions of emotional impact, social impact, symptom and functional impact, patients' views concerning treatment, and relationship with doctor. RESULTS: 1. Before and after treatment, the most serious impact was emotional dimension showing 1.90 and 1.30 in average score (AS), and social (AS: 1.14 and 0.83) and symptom and functional impact (AS: 1.05 and 0.92) was also affected. 2. In female rather than male, statistically more significant impact on patients' QOL was observed in all dimensions. 3. After treatment, 3 of 5 dimensions were improved significantly - emotional dimension (AS: from 1.90 to 1.30), social dimension (AS: from 1.14 to 0.83), patients' view concerning treatment(AS: from 1.34 to 1.02) 4. The degree of patients' satisfaction at the therapeutic effect was very high - 62.4% (immediately after. treatment) and 65.8% (9 months after initiation of treatment) of patients answered excellent or good. CONCLUSION: This study confirms that toenail onychomycosis has significant Impact on the overall QOL of patients. Also the effect of antifungal therapy on patients' QOL were satisfactory. Therefore, both doctor and patient should pay more attention to the treatment of onychomycosis.
