A twenty four-year-old female patient had suffered progressive dyspnea for 6 years until death. She denied any symptoms suggestive of connective tissue disease, or deep vein thrombosis. She suffered an episode of pontine infarct in 1995. Four years after diagnosis of primary pulmonary hypertension, she died of sudden death during hospitalization. Gross features of pulmonary arteries at autopsy were as follows: left main pulmonary artery showed dilation of the lumen and thickening of the wall, and right main pulmonary artery was markedly dilated and contained fresh thrombus. Hematoxylin and eosin-stained sections of lung tissue showed plexiform lesions of pulmonary arteries, complete luminal obliteration of pulmonary arterioles and dilated lesion of pulmonary arterioles, and capillaries. This patient represents a typical case with a primary pulmonary arteriopathy with plexiform lesions with thrombotic lesion, demonstrating the importance of thrombosis in situ in the pathogenesis of primary pulmonary hypertension. To our knowledge, this is the first autopsy report on the primary pulmonary hypertension in Korea.

The symptoms of the rheumatoid arthritis are variable enough to be ranged from mild to severe case. Synovectomy, fusion, and total knee replacement are to be applied according to the site and degree of involvement as surgical treatments. In the analysis, we compare the result of PCL retention TKR patients with those of PCL sacrificing TKR patients and of cemented TKR patients with those of cementless TKR patients. Function of the knee was evaluated using the knee score system of the Hospital for Special Surgery. From Nov, 1982 to Nov. 1990, total knee replacment was performed on 128 knees in 77 patients with rheumatoid arthritis at the Kyung Hee University Hospital and were followed for from two to ten years(average, four years eleven months). 1. The age at operation was ranged from 21 years to 72 years(average 53.2 years). There were seventy one female and six male patients. 2. The cruciate sacrificing prosthesis(group I ) were 42 cases and cruciate retention prosthesis(group II) were 86 cases. 3. The average preoperative range of motion was 85. 5 degree and the average post-operative range of motion was 107. 7 degree. Group I changed from 74. 7 degree to 105. 8 degree and Group II changed from 90. 5 degree to 108. 5 degree. 4. The average preoperative flexion contracture was 28. 7 degree and average post-operative flexion contracture was 7.8 degree. Group I changed from 37 degree to 8.4 degree and Group II changed from 24. 7 degree to 7. 5 degree. 5. The average preoperative tibiofemoral angle was varus 7. 4 degree in 69 cases and valgus 7. 6 degree in 59 cases. The average postoperative tibiofemoral angle was valgus 7. 2 degree. 6. The average preoperative knee Rating Score was 35. 2 point and the average postoperative score improved to 82. 7 point. Group I changed from 31. 3 point to 79. 4 point and Group II changed from 37 point to 84. 2 point. 7. 107 cases were cemented TKR and the 21 cases were cementless. There was no significant difference in those groups. 8. Additional operations were THR in eight cases, TER in five cases, TAR in four cases, TSR in one case, TWR in one case, Swanson prosthesis in one case, knee synovectomy in two cases, elbow synovectomy in three cases, and wrist synovectomy in two cases. 9. Complication included loosening in one case, partial ankylosis in three cases, and deep infection in one case.

Restless legs syndrome (RLS) is a neurogenic disorder with the patients having a sensation of discomfort and an urge to move continuously. These symptoms can get worse during night and cause sleep disturbance. These symptoms can be misdiagnosed as lower leg pain of a spinal origin and the treatment can be wrongly focused on this. This treatment for an unproven state of symptoms can place clinicians in a difficult situation. We experienced RLS associated with spondylolisthesis and spinal stenosis, and we originally misdiagnosed the patient and wrongly treated the patient operatively with spinal fusion and posterior instrumentation. After an insufficient result, we diagnosed the patient with having RLS with the help of the neurology department and rehabilitation medical department. In one other case we diagnosed a RLS patient with the help of a neurologist and the patients had arrived an our department for total knee arthroplasty and spinal root block. We report on these cases so other orthopedic surgeons will not make same mistakes.

The antihypertensive efficacy and safety of Dilevalol, compared with Nicardipine, were evaluated in mild to moderate hypertensive patients in a randomized crossover study. Following a 3 week placebo washout (phase I), the first crossover (phase II) was initiated with 63 patients randomized to dilevalol and 62 to nicardipine. The 6 weeks of treatment was initiated with 100mg of dilevalol once daily or 40mg of nicardipine (20mg B.I.D.). After 2 weeks, patients not achieving a sitting DBP to < or =90mmHg or a decrease of > or =10mmhg were uptitrated to 200mg Dilevalol once daily or 60mg Nicardipine twice daily. A second three week placebo washout (phase III) followed by a second 6 week active treatment phase (phase IV) during which patients were crossed over to the alternative therapy as during phase II if the sitting DBP again met the entrance criteria. 18 patients were only evaluable for the first washout and treatment period because of early discontinuation or protocol violations. They were included in the safety evaluation. phass II patients treated with Dilevalol (n=63) were mean age of 52.9 years, 49% male and 51% mild hypertensives (< or =105mmHg). Phase ??patients treated with Nicardipine (n=62) were mean age of 51.2 years 55% male and 66% mild hypertensives. Both Dilevalol and Nicardipine significantly and equivalently lowered blood pressure relative to baseline (71% versus 67% normalization). Dilevalol slightly but significantly lowered heart rate (-5 beat/min versus -1 beat/min). Dilevalol significantly increased HDL cholesterol (2.1mg/dl, 4.2%) and decreased total cholesterol (9.6mg/dl, 4.2%) while Nicardipine produced only a small but not significant reduction in total cholesterol (3.2mg/dl, 1.2%). The incidence of adverse effects were lower with Dilevalol than with Nicardipine and especially flushing and ankle edema occurred significantly more often with Nicardipine. in conclusion, dilevalol is equally effective but has a superior safety profile to nicardipine in the treatment of mild to moderate hypertension.

PURPOSE: To assess relative diagnostic value of Ga-67 planar, Ga-67 SPECT, and CT images for detection of head and neck tumors and cervical lymph node metastasis. MATERIALS AND METHODS: Thirty eight patients of pathologically proven head and neck tumors including squamous cell carcinomas(n=32), malignant lymphomas(n=3), undifferentiated carcinomas(n=2), adenocarcinomas(n=l) were enrolled in this study. Ga-67 planar and SPECT images were obtained with intravenous injection of 5mCi of Ga-67 citrate. On the basis of 30 and 20 mm in the greatest diameter of cervical lymph nodes, we compared lesion detectability of Ga-67 planar, SPECT, and CT. RESULTS: Thirty eight cases of head and neck tumors were detected in 29 cases(76.3%) with Ga-67 planar image, 37 cases(97.3%) with Ga-67 SPECT, and 32 cases(84.2%) with CT. 25 of 32 squamous cell carcinomas were positive with Ga-67 planar image and all of 32 cases with Ga-67 SPECT. Both of two undifferentiated carcinomas were positive with Ga-67 planar and SPECT images. Two of three malignant lymphomas were positive with Ga-67 planar image and all of three with Ga-67 SPECT. Eight of nine tumors were negative with Ga-67 planar image and those were less than 30ram. One case of adenocarcinoma was negative with Ga-67 planar and SPECT images. Seven of nine lymph nodes greater than 30mm were positive with Ga-67 planar image and all of nine with Ga-67 SPECT. On the basis of 20mm in greatest diameter, 16 of 21 lymph nodes greater than 20 mm were positive with Ga-67 planar and SPECT images. CONCLUSION: CT providing better resolution than Ga-67 scan permitted analysis of size and location of metastatic cervical nodes, however primary tumors of oral cavity, vocal cord, and nasopharynx were often not detected on CT when metallic and motion artifacts were present, where Ga-67 SPECT was useful. Ga-67 SPECT enabled better anatomical localization than Ga-67 planar image and was useful in detection of lymph nodes greater than 30 mm.
