Late aseptic loosening of the acetabular component following total hip arthroplasty become increasing frequently after about 10 years and has become a more severe problem both in frequency and severity than femoral component loosening. The complexity of acetabular revision depends largely on the reconstruction required to restore normal anatomy due to acetabular bone loss. The clinical and radiologic results of acetabular revision using a porocoated acetabular component fixed to the pelvis with screws were studied in 36 patients (40 hips) who had moderate or severe acetabular loss. Acetabular revision in patients whose bone stock had already been destroyed provied more formidable problems at revision surgery. The mean Harris hip score was improved 46 to 84. Bone graft union was achieved by 7.4 months and incorporated by 16 months. The graft bone resorption was noted minor degree lateral to the cup. Of 40 cases, 2 cases required re-revision of acetabular cup for identifiable failure of fixation and one was showed probable loosening. The results of the present study suggest that revision of the acetabulum with use of a hemispherical cementless component stabilized with multiple screws and morselized bone grafts filling bone defects appears to be successful in restoring bone stock and providing a stable, pain-free reconstruction.

It appears that frequency of fractures of the aceta ulum is increasing with the number of automobiles on our roads and when they occur they seem to pose difficulties of management. Because, the anatomy of this region is complicated, making surgical approaches difficult. Second, the patients often have major associated injuries, making early operative treatment hazardous. Third, the fractures are often severly comminuted, leading many surgeons to beleave that operative reduction is impossible. Finally, and unfortunately, the fractures are often missed. The aim of treatment must be to restore the fractured acetabulum to its normal anatomy followed by early motion to promote healing and restore function. Undisplaced acetabular fractures have a good prosis with conservative treatment but patients with displaced fractures of the acetabulum not reduced by manipulation and traction should be considered candidates for open reduction. The author experienced 72 cases of acetabular fracture patients who were admitted to the department of Orthopaedic Surgery of Catholic Medical College and Center from January 1979 to August 1983. The results of 48 patients who were followed up over 6 months period were as follows; l. Among 72 cases(44 were male and 28 were female), the most common causes of acetabular fracture was pedestrian struck by car. 2. 56 were treated conservatively and 16 were treated surgically. The result were as follows; Excellent-15(31%), Good-23(48%), Fair-8(17%), Poor-2(4%). 3. 72 cases were classified by Letournel classification. The most common type was posterior wall fracture(14 cases), and second most was T-shaped fracture(13 cases). 4. If the grossly displaced fragments are present they should be reduced and fixed surgically if surgical approach can be done. 5. It is essential to understand the pathologic anatomy of the acetabulum in order to approach the acetabular fracture sefely and with maximum ease.

Twenty-two cases of idiopathic myocardiopathy were observed during the period of 1962 to 1971 and follow up clinical study was made in 5 cases. The criteria of diagnosis was based mainly on exclusive diagnosis in etiology unknown marked cardiomegaly. 1) Male and female ratio of idiopathic myocardiopathy was 1.1:1 and age of onset were distributed from first decade to fifth decade with similar number of cases. 2) Cardinal symptoms were dyspnea, palpitation, chest pain and cough. Common physical findings were protodiastolic gallop (in 2 cases), moist rales (in 3 cases) and hepatomegaly(in 3 cases). 3) Laboratory findings were normal except elevated T.T.T. in one case. 4) Electrocardiogram were abnormal in all cases. There were 3 cases of left ventricular hypertrophy, 3 cases of non-specific ST-T changes and one case of first degree A-V block, intraventricular conduction defect, abnormal Q wave and low valtage, respectively. 5) After medical treatment, symptoms were improved in 4 cases but heart size was reduced in only one case and E.C.G. abnormalities were unchanged in all cases.

BACKGROUND: Urticaria pigmentosa(UP) is primarily a disease of children. There have been no clinical studies of UP in Korea. OBJECTIVE: This study was performed to find the clinical characteristics of UP in Korean child-hood patients. METHOD: Twenty-nine cases of urticaria pigmentosa confirmed clinically and histopathologically were analyzed. RESULTS: The maculopapular type was the most common with the usual age of onset before the age of 6 months, and the lesions tended to be distributed in the central portion of the body. Darier sign was positive in 92% of the patients(24/26). No systemic involvements were detected in any of the patients with minimal associated symptoms. Seven patients of the maculopapular type and one patient of the multiple nodular type followed up for more than 2 years showed a tendency to improve or clear by the age of 6 years. CONCLUSION: Neonatal or infantile-onset patients of UP in Korean pediatric population were considered to have a benign clinical course and to require no aggressive therapy.

Nerve conduction study has been an important part of electrodiagnosis and has been utilized as a clinical diagnostic technique in diabetic neuropathy. But conduction study of the more proximal segment has been a few reports. This study demonstrated segmental method for obtaining orthodromic motor nerve conduction and mixed nerve conduction, and antidromic distal sensory nerve conduction in diabetic group and normal group. The purpose of the study was to determine diagnostic value of segmental nerve conduction in diabetic neuropathy. The results were as follows: 1. Significant difference at P<0.01 between diabetic group and normal group; in median motor terminal latency, median motor nerve conduction velocity at axilla-elbow segment and elbow-wrist segment, median sensory nerve conduction velocity at wrist-elbow segment, ulnar motor and sensory conduction velocity at wrist-elbow segment, posterior tibial motor nerve conduction velocity at popliteal fossa-ankle segment, peroneal motor nerve conduction velocity at fibula head-ankle segment. 2. No significant difference at P>0.05 between diabetic group and normal group; in ulnar motor terminal letency, ulnar sensory nerve conduction velocity at axilla-Erb's point segment and finger-wrist segment, peroneal motor terminal latency and peroneal motor nerve conduction velocity at popliteal fossa-fibula head segment, posterior tibial motor terminal latency, sural sensory nerve conduction velocity. 3. The nerve conduction of proximal segment is more statistically significant than that of distal segment.

PURPOSE: Human umbilical vein endothelial cells(HUVECs) play an important role in regulating blood flow by releasing vasoactive substances. It has been reported that endothelial impairment and dysfunction might be a primary cause of placental vascular disease, which is manifested clinically as preeclampsia in mother and intrauterine growth restriction in fetus. Furthermore, the frequency of apoptotic changes is increased in umbilical and placental tissues from growth-restricted pregnancies. However, the various mechanisms of umbilical endothelial cell apoptosis have not been broadly proposed. We investigate the effects of amiloride derivatives on apoptotic death of HUVECs and identify their ionic mechanism. METHODS: HUVECs were purchased from Clonetics, and cultured on endothelial cell growth medium. MTT assay and flow cytometry were used for assessing cytotoxic effect and confirming the apoptosis. Changes in intracellular ion concentrations were measured with specific fluorescent dyes and fluorescence imaging analysis system. RESULTS: Amiloride derivatives elicited cytotoxic effects on HUVECs with dose-dependent manners and the rank order of potency is HMA(IC50 11.2 micrometer), MIA>EIPA>>amiloride. HMA-induced cytotoxicity is dependent on extra- and intracellular pH, that is, increase extra- and intracellular pH augmented the cytotoxic effects of HMA. HMA dose-dependently reduced intracellular major ions, such as K+ and Cl-. Interestingly, the depletion of intracellular ions induced by HMA was also significantly enhanced at alkaline extracellular pH. CONCLUSION: Amiloride derivatives induce apoptosis of HUVECs with dose and pH dependent manners. They reduce intracellular K+ and Cl- concentration, which is also extracellular pH dependent.

In the orthopedic Department of Jeonbug National University Hospital, twenty-five open tibial shaft fractures were reviewed and analyzed with osteomedullography and bone scanning with radioactive isotopes from June 1981 to October 1983. The results are as follows. 1. The cases of injury were mostly traffic accident(70.8%) and majority was found between second decade and third decade. Males were 11 times more frequent than females. 2. In the shape and location of fractures, comminuted fracture(60%) was most common, and fracture of middle one third(48%), lower one third(28%) were in order. 3. In the open tibial fractures, Grade I. of soft tissue injury was most frequent(64%). As inthe plate fixation was required, we should it placed atypically on the posterior surface of the tibia. 4. In the osteomedullography at 3 months after treatment, the rate of positive finding was 80 and intraosseous crossing vein(Kaski sign 1) was observed most frequently. 5. In the profile of the bone scanning with radioactive isotopes, the rate of single-peak uptake was 76% and twin-peak uptake was 24%. 6. In the negative Osteomedullogram and twin-peak uptake on the profile of the bone scanning, bone graft was necessary. 7. In the case of difficult diagnosis for union process of tibia fracture, osteomedullography and bone scanning with radioactive isotopes were considered useful method of early diagnosis.

PURPOSE: Anal condyloma is an epithelial proliferative lesion caused by human papillomavirus (HPV) infection. The present study analyzed the HPV types detected in HIV (+) Korean anal condyloma using PCR-based DNA microarray. METHODS: DNA was extracted from the condyloma tissue of 17 patients including 9 HIV (+) patients (M:F=15:2, mean age 35 years, 22~59 years). The 1st PCR was performed with a general primer on L1 region, and nested PCR on the products of the 1st PCR. PCR products were hybridized with a DNA chip. RESULTS: Fourteen patients (9 HIV (+), 5 HIV (-)) showed positive HPV DNA. Overall, type 6 was the most common (N=11), and type 11 (N=6), type 53 (N=3) in order. Among HIV (+) patients, type 6 was also the most common (N=7), then type 11 (N=5) and type 53 (N=3). In contrast to the HIV (-) patients, 5 patients (55.6%) proved to have multiple infections in HIV (+) patients (2 double, 2 triple, 1 quadruple infection). Four of 9 HIV (+) patients (44.5%) showed co-infection with high-risk HPV. CONCLUSION: Multiple infection and co-infection with high-risk types are more prevalent in HIV (+) condyloma patients compared to HIV (-) patients. HPV types on HIV (+) male anal condyloma are similar to those detected in the Korean female uterine cervix.
