A clinical analysis was performed on 61 cases of patent ductus arteriosus experienced at Yeungnam University Hospital during 3 years period from April, 1984 to December, 1986. Of the 61 patient of PDA, 13 patients were male and 48 patient were female and age ranged 2 months to 26 years old with the average age of 9.4 years. The chief complaints on admission were frequent URI and dyspnea on exertion. diagnostic procedure were Doppler echocardiogram (in 53 among 61). Three postoperative complication were developed, but there was no operative mortality.

Ventricular septal defects is most common congenital cardiac anomaly in Korea and worldwide. And its clinical spectrum is well known. The anatomic classification had been undertaken by several authors, but recently Dr. Soto and Anderson's classification is widely used instead of Dr. Kirklin's it. From April, 1984 to December 1986, 99 cases of ventricular septal defects had been taken surgical repair under direct vision using conventional cardiopulmonary bypass technique at Yeungnam university hospital. The clinical spectrum was similar to other hospital, and postoperative mortality was 2%, the most common associated anomaly was patent foramen ovale, and the most common postoperative complication was incomplete or complete right bundle branch block. The rank of defects was as followings: 45 perimembranous inlet type, 21 doubly committed subarterial type, 17, perimembranous trabecular type, and 16 perimembranous outlet type. There was no muscular and mixed type.

During 1986, 111 cases of open heart surgery were performed at Yeungnam University Hospital consisting 88 cases of congenital heart disease and 23 cases of acquired heart disease. Among 88 congenital heart disease, 72 were acyanotic group and 16 were cyanotic. Common congenital heart diseases were ventricular septal defect (51%), atrial septal defect (18%) and Tetralogy of Fallot (16%). Among 23 acquired heart disease, 22 cases were valvular heart disease and one was dissecting aortic aneurysm. Three cases of the postoperative death were present resulting 2.7% of surgical mortality rate.

PURPOSE: We wanted to compare the effectiveness, safety and cost of performing extracorporeal shock wave lithotripsy (ESWL), and so we reviewed the outcomes of patients with urinary calculi that were treated with the EDAP LT-02 lithotriptor (LT-02) and the Sonolith Praktis lithotriptor (Sonolith). MATERIALS AND METHODS: 2,141 cases treated with the LT-02 and 198 cases treated with the Sonolith were retrospectively reviewed. The success rate and the number of sessions, according to the size and location of the stones, were statistically analyzed. Auxiliary measures, other treatment modalities, complications and the running cost of the entire treatment were also reviewed. RESULTS: The success rate (stone free or residual fragments <4mm in diameter) between the LT-02 and Sonolith, according to the stone size and location, showed no significant difference. The overall success rate was 96.4% and 96.5%, respectively. The mean number of treatment sessions was 3.0 for the LT-02 and 2.0 for the Sonolith. The efficiency quotient was 45.5 for the LT-02, which was lower than 54.0 for the Sonolith. No significant difference was observed in the occurrence rate of complications and the auxiliary measure rate between the LT-02 and the Sonolith. The cost of overall treatment was 1.33x10(6) won for LT-02 and 1.12x10(6) won for Sonolith. CONCLUSIONS: The results suggest that the efficacy of the Sonolith is approximately equal that of the LT-02. However, the Sonolith has superiority in reducing the number of treatment sessions and lowering the overall treatment cost.

BACKGROUND: To determine the benefit of an extensively porous coated femoral stem in patients receiving revision total hip arthroplasty. METHODS: This study reviewed the results of 35 patients who received a revision total hip arthroplasty with extensively porous coated femoral stem between August, 1996, and December, 2002. The mean follow-up period was 77.5 months. The clinical and radiological results were evaluated by the Harris hip score and serial roentgenographic findings. RESULTS: The preoperative and postoperative Harris hip score was 68.3 and 92.5, respectively. Radiographically, none of the acetabular components showed any evidence of migration, tilt, rotation, or shedding of metal particles. In addition, none of the femoral components showed evidence of subsidence, pedestal, or shedding of metal particles. Twenty-two hips had a mild stress shield and 2 hips had a moderate stress shield. The perioperative complications encountered were deep vein thrombosis (1 case), mild heterotopic ossification (4 cases), intraoperative periprosthetic fractures (1 case), and nonunion of the trochanteric osteotomy site (2 cases). CONCLUSIONS: Extensively porous coated femoral stems and acetabular components produce excellent clinical and radiological results in revision total hip arthroplasty.

Hydatid disease is Echinococcus granulosus infection in its larva form. It is endemic in many sheep- and cattle-raising countries throughout the world. In Korea seventeen cases have been reported but relapsed case is not. We report relapsed hydatid disease in pelvic cavity 10 years after primary surgery for Echinococcal cysts in the liver and pelvic cavity. The cysts were surgically removed and the patient was managed with postoperative adjuvant treatment with albendazole and followed with serologic test for anti-echinoccocus antibodies by ELISA.

Insulin-like growth factor binding proteins (IGFBPs) are important components of insulin growth factor (IGF) signaling pathways. One of the binding proteins, IGFBP-5, enhances the actions of IGF-1, which include the enhanced proliferation of smooth muscle cells. In the present study, we examined the expression and the biological effects of IGFBP-5 in vascular smooth muscle cells (VSMCs) from spontaneously hypertensive rats (SHR) and Wistar Kyoto rats (WKY). The levels of IGFBP-5 mRNA and protein were found to be higher in the VSMC from SHR than in those from WKY. Treatment with recombinant IGFBP-5-stimulated VSMC proliferation in WKY to the levels observed in SHR. In the VSMCs of WKY, incubation with angiotensin (Ang) II or IGF-1 dose dependently increased IGFBP-5 protein levels. Transfection with IGFBP-5 siRNA reduced VSMC proliferation in SHR to the levels exhibited in WKY. In addition, recombinant IGFBP-5 significantly up-regulated ERK1/2 phosphorylation in the VSMCs of WKY as much as those of SHR. Concurrent treatment with the MEK1/2 inhibitors, PD98059 or U0126 completely inhibited recombinant IGFBP-5-induced VSMC proliferation in WKY, while concurrent treatment with the phosphatidylinositol-3 kinase inhibitor, LY294002, had no effect. Furthermore, knockdown with IGFBP-5 siRNA inhibited ERK1/2 phosphorylation in VSMC of SHR. These results suggest that IGFBP-5 plays a role in the regulation of VSMC proliferation via ERK1/2 MAPK signaling in hypertensive rats.

PURPOSE: We evaluated the correlation of the anatomic parameters of the acromion those represent on the magnetic resonance image (MRI) of impingement syndrome. MATERIALS AND METHODS: From June, 2004 to December, 2005, 71 cases were surgically proven to be impingement syndrome, and the anterior acromial hooking angle, the lateral acromial hooking angle (AAHA and LAHA) and the acromial hooking index (AHI: the sum of the AAHA and LAHA) were compared to 16 control cases. At the same period, 55 cases were surgically proven to be partial or full thickness rotator cuff tear, and age, gender and twelve anatomic parameters, including the acromial type, the acromial angle, the anterior covering, the acromial slope, the AAHA, the lateral acromial angle, the acromial torsional angle, the lateral acromial angulation, the LAHA, the lateral covering, the acromiohumeral distance and the AHI were assessed. RESULTS: The AAHA and AHI were increased as impingement syndrome proceeded. The acromial type and acromial angle, and the AAHA, LAHA and AHI showed significant differences between the controls and the rotator cuff tear patients on univariant analysis. On multivariant analysis, gender was most strongly correlated with rotator cuff tear. Age, AAHA and the acromial angle showed similar correlation, respectively. CONCLUSION: The coronal acromial shape is correlated with rotator cuff tear, and it is important to correct the lateral acromial shape when performing acromioplasty.
