Recently, tuberculosis of bone and joint is decreased with good nutrition and environment, development of preventive medicine and improvement of treatment regimen. But it is still one of the common inflammatory diseases in Korea, and must be considered in the differential diagnosis of common orthopedic complaints. There are few reports on extraspinal tuberculosis of bone and joint. Forty one cases of extraspinal tuberculosis of bone and joint were studied in our department from January 1988 to August 1993. The results were as follows; l. Extraspinal tuberculosis of bone and joint were 41 cases (39 patients, 27.8% of 147 tuberculosis of bone and joint including spine). 2. The proportion of children and young adults was 56%, hips were involved in 11 cases, knee joints in 8 cases, ankle joints in 6 cases, feet in 6 cases and elbow joints in 5 cases. 3. Coexisting pulmonary tuberculosis was found in 19 patients and active lesion in 15 patients. 4. Confirmative diagnosis could be made by smear and culture of the lesion or pathologic findings or recently available polymerase chain reaction(PCR) method. 5. Various treatment, such as antituberculous medication, external immobilization, synovectomy, curettage and bone graft, arthrodesis, had been carried out. 6. Reactivation of other site was found in 7.3%(3 cases) and resistant tendency was found in 9.7%(4 cases).

High tibial osteotomy is a useful procedure in the treatment of early stage osteoarthritis of the knee which is confined to the medial compartment. But long term follow-up study of high tibial osteotomy has not been provided yet and its prerequisite for a successful result still remains unrevealed. Since the osteoarthritis can progress after the osteotomy, it may result in the loss of correction and recurrence of pain and require conversion to total knee replacement arthroplasty. We studied clinically and radiologically the long term result of high tibial osteotomy in 11 patients(16 knees) who had been treated at the Department of Orthopaedic surgery of Seoul Paik Hospital during the period from January, 1978 to May, 1989, and follow-up for longer than 4 years. Preoperative mean varus angle was 6.4 degrees and immediate postoperative mean valgus angle was 8.6 degrees and final mean valgus angle was 4.7 degrees. The average loss of correction angle was 3.9 degrees. At 2-year follow-up, the results of 16 knees were as follows; excellent in six knees, good in seven knees. The final results at average 7.2-year follow-up were excellent in four knees, good in six knees and one knee was converted to total knee replacement arthroplasty. The results showed deterioration of clinical results and loss of correction with time after osteotomy. However, in more than half of the cases the results were good or excellent at the final follow-up, We, therefore, conclude that high tibial osteotomy is still a useful procedure in osteoarthritis of the knee if performed with a precise surgical technique and an adequate overcorrection more than 10 degrees.

The mortality and morbidity of peritrochanteric fractures in the elderly are great due to preexisting diseases, the osteoporosis, and poor general conditions. Since the complications sometimes lead to death, it is utmost important to reduce the complications and to prevent them. Authors had experienced 42 peritrochanteric fractures over 65 years old from January, 1988 to December, 1992. Age incidence was distributed from 65 to 93 years. The sites of fractures were 17 femoral neck, 24 intertrochanteric, 1 subtrochanteric. The mortality at postoperative 6 months was 10.2%. The postoperative complications were 6 cardiovascular diseases, 3 pneunonia, 3 pressure sore etc. The results according to interval between injury and operation were not significant, but reducing risk factors following check-up of general conditions was significant. It was necessary in treatment of elderly peritrochanteric fractures to check the general conditions, to reduce risk factors, to choose appropriate method of operation and anesthesia, and to operate as soon as possible by experienced surgeon. Postoperative early ambulation was also significant at good results. The percutaneous pinning under local anesthesia was an recommendable method in patients with severely poor general conditions.

To determine the perinatal mortality and morbidity of fetuses with absent end-diastolic velocities (AEDV) of the umbilical artery in severe pre-eclampsia and eclampsia, the outcome of 5 fetuses with AEDV was compared with that of 35 fetuses with positive end-diastolic velocities (PEDV). The study population comprised 38 cases of severe pre-eclampsia and 2 cases of eclampsia with structurally normal singletons, who had had umbilical artery Doppler velocimetry weekly from admission to delivery. The Doppler velocimetry result was not used for the clinical management. Perinatal death and neonatal morbidity from both groups were further examined in gestational age category to control the influence of preterm births. The incidence of AEDV of the umbilical artery Doppler velocimetry in severe pre-eclampsia and eclampsia was 12.5% (5/40). The AEDV group had a significantly higher incidence than the PEDV group in terms of ceasarean section due to fetal distress (60% : 17%), Apgar score < 7 at 5 minutes (60% : 14%), perinatal death (25% : 0%) and assisted mechanical ventilation (67% : 9%) both at 32-36 weeks. Time intervals from the detection of AEDV to delivery of live neonates varied from the day to 15 days. In conclusion, AEDV in the umbilical artery might be of clinical value in routine surveillance of pregnancies complicated by severe pre-eclampsia and eclampsia, and predict hypoxic fetal condition which needs operative interventions before or during labor and mechanical ventilation after birth.

Pneumocystis carinii causes serious pulmonary infection in immunosuppressed patients. This study was undertaken to observe the cytoskeletal proteins of P. carinii by immuno-electron microscopy. P. carinii infection was experimentally induced by immunosuppression of Sprague-Dawley rats for seven weeks, and their lungs were used for the observations of this study. The gold particles localized actin, tropomyosin, and tubulin. The actin was irregularly scattered in the cytoplasm of the trophic forms but was much more concentrated in the inner space of the cell wall of the cystic forms called the inner electron-lucent layer. No significant amount of tropomyosin was observed in either trophic forms or cystic forms. The tubulin was distributed along the peripheral cytoplasm and filopodia of both the trophic and cystic forms rather than in the inner side of the cytoplasm. Particularly, in the cystic forms, the amount of tubulin was increased and located mainly in the inner electron-lucent layer of the cell wall where the actin was concentrated as well. The results of this study showed that the cell wall of P. carinii cystic forms is a structure whose inner side is rich in actin and tubulin. The location of the actin and tubulin in P. carinii suggests that the main role of these proteins is an involvement in the protection of cystic forms from the outside environment by maintaining rigidity of the cystic forms.

Choriocarcinoma is a relatively rare malignancy of which characteristic is rapid metastasis to the other organs. It is related to the previous gestation or originated from the teratoma. Choriocarcinoma is mostly originated from the intrauterine chorionic villi, but it is rarely originated from the utreine cervix, fallopian tube, ovary, vagina and pelvic cavity. Primary choriocarcinoma of the fallopian tube is exceedingly rare and it is originated from ectopic tubal pregnancy, tubal migration from the intrauterine pregnancy or intratubal teratoma. 9 Symptoms and signs of the choriocarcinoma originated from the ectopic pregnancy are abdominal pain, vaginal bleeding, palpable adnexal mass, positive pregnancy test and amenorrhea. Thus it is difficult to distinguish choriocarcinoma from ectopic pregnancy on the basis of symptoms before the microscopic diagnosis presented.20 Effective treatment of choriocarcinoma is chemotherapy. Additional operation is possible. B-HCG is a useful measure for the follow up. We experienced a 36-year-old multigravida Korean woman who was diagnosed as the rupture of ectopic pregnancy after left salpingectomy in our hospital and then confirmed primary choriocarcinoma of the fallopian tube without metastasis on microscopic finding. Postoperative chemotherapy was performed with methotrexate. The follow up of disease is still on going at two month intervals and she has remained healthy, We report this case with review of literatures.

PURPOSE: Stroke is one of the leading causes of death in Korea. Atherosclerotic disease in the carotid artery bifurcation is the most common cause of stroke. The carotid artery calcification is easily appreciated by CT (Computed tomography). CT is often taken in a dental hospital for the diagnosis of inflammation, injury, cyst or tumor on maxillofacial region. However, there was no report of carotid artery calcification on CT in dental patients. This study was to determine the prevalence of carotid artery calcification on CT in dental patients. MATERIALS AND METHODS: The presence of carotid artery calcification was evaluated by an experienced radiologist on CT scans of 287 patients (166 males, 121 females, average age 42, range 6 to 86 years) and the medical history of the patient and the interpretation of CT were reviewed. RESULTS: Carotid artery calcification was detected on CT scans of 57 patients (19.8%; 35 males, 22 females). All the male patients with carotid artery calcification were older than 50, and all the female patients with carotid artery calcification were older than 60. Among the 57 patients, 10 had Diabetes mellitus, 20 had cardiovascular disease, 3 had history of stroke and 3 underwent radiation therapy for head and neck cancer. Carotid artery calcification was not included in the interpretation of CT of dental patients except one patient. CONCLUSION: The prevalence of carotid artery calcification on CT of dental patients was about 20% in this study. Carotid artery calcification should be included in the interpretation of CT of dental patients.

The glucose uptake rate by plerocercoid of Diphyllobothrium sp. was a mean value of 5.35+/-0.80 micro-mole/hr/g of wet wt, and total CO(2) production rates by the plerocercoid larva averaged 7.54+/-0.73 micro-mole/hr/g of wet wt. The relative specific activity into respiratory CO(2) showed a mean value of 7.30 +/-0.90 per cent. The rate of CO(2) production derived from medium C(14)-glucose was a mean of 0.58+/-0.13 micro-mole/hr/g of wet wt. Therefore, the average value of 1.92+/-0.38 per cent of glucose utilized by the larvae from the medium C(14)-glucose was oxidized to respiratory CO(2). The tissue concentration of glycogen in plerocercoid larva was a mean of 46.28 +/-2.23 mg/g or 4.63+/-0.22 per cent/g of wet wt., and the turnover rate of glycogen pool was a mean of 0.049 +/- 0.012 %/hr or 0.010 +/- 0.003 mg/hr/g of wet wt. The average value of 2.76+/-1.00 per cent of glucose utilized by the larvae from the medium C(14)-glucose was incorporated to the glycogen. These data accounts for that only 5 per cent of the utilized glucose by the plerocercoid larvae participated in furnishing the oxidation into respiratory CO(2) and the synthetic process into glycogen.
