Orthopaedic wire has been used widely as a good internal fixator in cases of fracture, the ligament reconstruction, and for the stabilization of cervical spine. But if it is used inappropriately, a wire can be easy to fail by elongation, untwisting, or breakage. Among them, the most common failure of wire is breakage. To clarify the mechanism and the causes of wire failure, the authors analysed serial roentgenograms and scanning electronmicroscopic findings of broken wire in total 13 cases, which were experienced at the department of orthopaedic surgery, St. Mary's Hospital, Catholic University Medical College From January 1981 to December 1987. The results obtained were as follows :1. The mechanism of wire failure were classified into the 4 types ; minor continual flexing motion in 6 cases, repeated minor back and forth torsion in 1 case, tension failure in 2 cases and combined type in 4 cass. 2. The causes of wire failure were in appropriate use and inadequte application, a lack of s ufficient mechanical strength, micromotion due to inadequate postoperative imm obilization, early mobilization before tissue healing as well as certain injuries to the wire during handling in operation.

Plasma sprayed coating of the hydroxyapatite(HA) are biocompatible and may contribute to the early fixation of total joint prosthesis. We studied 64 hips(58 patients) who had hydroxyapatite coated primary total hip arthroplasty during the period from January 1992 to June 1993 about clinical and radiological result prospectively. The components have been followed for a minimum of 26 months and an average 31 months. Harris hip score averaged 92 at most recent follow up intervals. At the last follow up, the pain in 7 cases(11%) respectively and only slightly to mild in mostly. Although thigh pain has been occurred in 7 cases(11%), all patients had not trouble in daily activity. In radiological evaluation, there was a rapid and good endosteal bone formation of implants with bone apposition on the Gruen zone 2 and 6 of HA coating area. No radiolucent line formation was detected around HA coated area. In acetabular component, the endosteal bone formation was found in 12 cases and the radiolucent line was occurred in 4 cases. No revision were done for the femoral and acetabular component. The result of the study indicate that this hydroxyapatite coated component can provide satisfactory clinical and radiological result. Further prospective follow up is necessary to determine whether the favorable early result of this implant are maintained over longer period.

The 68 cervical cerclage operations of incompetent internal os of the cervix(IIOC) were performed at the Taegu Catholic Medical Center from Jan. 1, 1990 to Dec. 31, 1995. The results of this study were as follows: 1. The incidence of operation for IIOC was 0.23% of total delivery. 2. Highest number of IIOC was observed in the age group of 25 to 29, and the average number of pregnancy before operation was 4.1. 3. The significant contributory factor was previous history of the induced or spontaneous abortion. 4. In all cases, cerclage method was McDonald operation. 5. The average fetal salvage rate after operation was 82.5% and from the 14th week to 16th week of gestation(43 cases), the success rate of operation was 85%. 6. The causes of operation failure were premature labor in 6 cases(55%), premature rupture of membrane in 3 cases(27%) and abortion in 2 cases(18%) in order.

We present a case of angiographically-confirmed transverse and sigmoid sinus thrombosis, image with MR, in a 20 year old male with a history of otitis media and maxillary sinusitis. T1-weighted image demonstrated an isosignal intensity mass with tubular-shaped low signal intensity in right transverse and sigmoid sinus. The thrombus had high signal intensity on T2-weighted image. The signal intensity of the thrombus on Gd-DTPA enhanced T1-weighted image was unusually high similar to that of transverse sinus. Although dural sinus thrombosis has a non-specific MR signal intensity, findings of MRI in this case may serve as an aid in future evaluation of venous thrombosis.

This study was conducted to evaluate the effect of ambroxol on preventing the infantile respiratory distress syndrome (IRDS) in preterm birth at the Dept. of Obstetrics and Gynecology of Taegu Catholic Medical Center during the period from Jan. 1996 to Dec. 1996. Total of 68 cases were evaluated including 16 ambroxol group and 52 control group. The result were as follows : 1. In the comparison of preventing IRDS, there was 0 case of IRDS in ambroxol group and 7 cases of IRDS in control group (13.46 %). There was a significant difference between two groups (p<0.05). 2. The side effects of ambroxol after administration were nausea in 5 cases, headache in 3 cases, and chest discomfort in 4 cases, but these were not serious and self controlled. 3. There was no significant difference in neonatal morbidity between two groups (p > 0.05).

CT findings and comparison between clinical and CT staging were reviewed in 45 consecutive patients withbiopsy proven carcinoma of the cervix. CT was done for staging of primary untreted cercial cancer in 36 patientsand for diagnosis of recurrent cervical cancer or follow-up study 14 times in 9 patients . The results are asfollows; 1. As comparing with clinical staging in 36 cases, CT agreed with clinical stage in 19 cases (52.8%),upstaged in 10 cases(27.8%) and downstaged inn 7 cases (19.4%). 2. The main upstaged CT findings are detection ofunsuspected bladder or rectal invasion and paraaortic lymph node metastasis. Inadequate delineation ofintravaginal tumor was the leading causes of understage of CT than clinical one. 3. CT detected all 10 cases ofthe hydronephrosis shown by IVP and detected unsuspected bladder invasion in 3 cases. 4. CT was valuable in thediagnosis of recurrent tumor and follow-up study after treatment. 5. CT offeres distinct advantages over clinicalstaging and can be integrated into the present FIGO classification of uterine cervix carcinoma. CT can served asan initial radiological staging work-up of primary of recurrent cervical carcinoma.

The pulsed laser lithotripsy has been used in the treatment of urinary calculi. We treated 153 patients of stones, via the pulsed dye laser(Technomed Pulsolith) with 7.5 and 6.5 F. rigid ureteroscope between January 1992 and January 1995. Stones were in bladder(4 cases), upper ureter(17), mid ureter(31) and lower ureter(101). The laser lithotripsies were applied for impacted stones and relatively large stones(more than 6 mm) The success rates according to location were 47%(8/17) in upper ureter, 77%(24/31)in middle ureter, 95%(96/101)in lower ureter and 100%(4/4) in bladder and mean success rate was 86% (132/153). There were 21 failures due to upward migration(9 cases), poor visual field(7), laser resistant stone(3) and malfunction of laser(2). Complications were showed in 28 cases that were gross hematuria(16 cases), ureteral perforation(6), fever(4) and ileus(2), but most of them might be related to ureteroscopy rather than laser, and all of them were resolved with conservative management. So laser lithotripsy is safe and effective method of middle and lower ureteral calculi, and upward migration of stones, the major cause of failure may be resolved by use of extracorporeal shock wave lithotripsy and flexible ureteroscope.

In 2007, the Public Sanitation Administration Law in Korea was partially amended to subdivide cosmetology into general and skin cosmetology. Thus starting from 2008, a skin cosmetology qualification requirement license was newly created in Korea. Instead of improving the health standards concerning public health, the amendments have exaggerated the monopolistic right of trade of the Korean Central Esthetician's Association with the assistance of the Division of Sanitary Policy in the Korean Ministry for Health. In addition, the amended ordinances stipulate that cosmetologists can analyze skin conditions, hence allowing medical diagnostic procedures by non-medical personnel which has serious health problems causing serious conflict with Korean Medical Law. Legislation precedents from around the world demonstrate that medical supervision by physicians is absolutely necessary with fastidious requisitions in order to safeguard public health. However, in Korea there is a subversive attempt by some esthetician groups to limit the employment of estheticians by medical institutions in order to safeguard their private privileges. The newly amended Public Sanitation Administration Law should be revised in order to preserve the fundamental rights of the people, to enhance public health, and to uphold the well being of the people instead of catering to special interest groups.

PURPOSE: To analyze contrast-enhancement pattern of stomach cancer on dynamic MRI and to verify the efficacy of intravenous contrast agent in the evaluation of stomach cancer. MATERIALS AND METHODS: Twelve patients with proven stomach cancer underwent dynamic MRI, By using 1.0T scanner, we obtained precontrast FLASH images, and 30, 60, 90 second delay FLASH images after intravenous contrast injection. All patients ingested on liter of water and had intramuscluar injection of Buscopan just before MR study. For quantitative analysis we measured signal to noise ratio (S/N) of stomach cancer on each image, and signal difference to noise ratio (SD/N) between cancer and intraluminal fluid, cancer and the pancreas. For qualitative analysis two radiologists evaluated lesion conspicuity on each image by grading system(grade 0, 1, 2, 3: poor, fair, good, excellent). RESULTS: S/N of stomach cancer increased gradually by time(precontrast, 30, 60, 90 second delay:38.7, 42.5, 57.4, 65.7). SD/N between cancer and intraluminal fluid significantly increased after contrast enhancement(1.24, 25.01, 39.30, 45.89). SD/Ns between cancer and the pancreas were 10.5, 9.33, 9.99, 10.66 respectively. In qualitative analysis, precontrast images were better than postcontrast images for delineation of stomach cancer, Postcontrast images showed clear endo-luminal side of stomach cancer, but outer margin of stomach cancer was more distinct on precontrast images. CONCLUSION: Precontrast MR images are better than postcontrast MR images in the depiction of stomach cancer. Intravenous contrast agent is not imperative in the evaluation of stomach cancer.
