Pseudo-Bartter syndrome is a rare medical disease of the kidney characterized by normal blood pressure, hypokalemic metabolic alkalosis, hyperreninemia and hyperaldosteronism with drug history of diuretics. We report US, CT and MRI findings of a patient with clinically proved pseudo-Bartter syndrome. The patient was a 37-year-old woman with a history of long term ingestion of the diuretics(furosemide) for 20 years. Renal US revealed hyperechoic renal medulla at both kidneys. The resistive index(RI), calculated from the duplex doppler waveform is 0.61. Unenhanced CT revealed faint high attenuation along the medulla. Tl-weighted MRI revealed indistinct corticomedullary differentiation.

Fracture-Dislocation of the the body of the hamate is rare in carpal bone fractures. Recently, we experienced two patients with coronal fracture of the dorsal aspect of the hamate with dorsal subluxation of metacarpal bases of the ring and little fingers. The mechanism of injury was by indirect blow with c1enched fist in two patients. Two patients were treated with closed reduction and plaster immobilization for 6 weeks and physical theraphy. At 13 and 14 weeks follow-up respectively, two patients had no funtional limitation, no complaints referable to hand, and nearly solid union on radiographs. We report two cases of fracture of the the body of the hamate bone, associated with dorsal subluxation of hamatometacarpal joint treated by conservative methods and review of literatures.

Kuntscher introduced the interlocking nail as the name of Detensionsnagel at 1968. Klemm, Kaessman, Hempel used it clinically through transverse hole. Authors tried to make the sagittal hole at the dorsum of the Kiintscher nail, which was interlocked- from the slot to the hole by bone screw. The direction of the sagittal hole crossed right angle to the transverse hole. Analysis of 35 cases conducted following conclusion. 1. Transfixing the screw at the sagittal hole of the nail can be done easily when transfixing through the transverse hole is difficult. 2. There was no difference in stability between transverse hole and sagittal hole transfixation. Lateral movement of the nail was disappeared after transfixation of the screw at the sagittal hole. Interlocking system is very similar to Harrington distraction rod system. 3. One case of nail breakage had occured at the transverse hole. Nail breakage easily occurs if the hole is situated near the fracture site. For prevent nail breakage larger nail insertion is desirable. (More than 14mm in femur and more than 12mm in tibia.) 5. Indication of the I-M nailing is widened by screw interlocking: from the subtrochanteric fracture to the supracondylar fracture of the femur. It is also useful in arthrodesis of the knee joint. 6. Addition of the Interlocking in ordinary I-M nailing patient could walk 3 to 10 days after operation and radiologic union achieved 12 to 20 week after opeation.

Analyses were done on one hudred and twenty caaes of bleeding gastric ulcers diagnosed by emergency endoscopy for the past five years. The reaults are as the following: Much more cases were found in male than female and the most prevalent age group was 6th decade. The body of stomach along the lesser curvature was the most common bleeding site. No age related difference was noted in bleeding sites. Most common type of ulcer was in the round and shallow form. Five of six cases with exposed vessels showed atrophic changes in surrounding mucosa. Among the probable precipitating factors, analgesica, alcohols and certicosteroids were found in such order,

PURPOSE: To evaluate the radiologic characteristics of axillary lymph nodes which are found on mediolateral oblique(MLO) view of mammography and to assess their clinical significance. MATERIALS AND METHODS: We retrospectively evaluated 119 cases axillary lymph nodes on MLO view of 410 cases of mammography in 205 patients regarding the size, bilaterality, number, grade of density, presence of central lucency, calcification of lymph nodes and presence of associated parenchymal pathologic lesions in breast. RESULTS: Axillary lymph nodes on MLO view were demonstrated in 119 (29%) among 410 cases. Axillary lymph nodes(112 cases) in cases without breast parenchymal lesions or with benign breast lesions showed; unilaterality in 68 cases(61%), smaller than 1.5cm in 100 cases(89%), lower density than breast parenchyma in 99 cases(88%), presence of central lucency in 99 cases(88%) and calcification in 3 cases(2.7%). Axillary lymph nodes(7 cases)in cases with breast cancer showed small size of less than 1.5cm in 4 cases(57%), absence of central lucency in 7 cases(100%) and iso-to higher density than breast parenchyma in 7 c&ses(100%). CONCLUSION: Axillary lymph nodes noted on MLO view of mammography, more than 1.5cm in diameter, absence of central lucency and iso to higher density than breast parenchyma could be suggested as clinically significant.

Primary hemangiopericytoma of chest wall is very rate and only a few cases have ever been reported. The tumor aries from the capillary pericyte of Zimmerman. It is a highly vascular slow growing tumor which can be calssified as both malignant and benign varieties. We report a case of a 66 year-old man in whom recurrent hemangiopericytoma was treated by complete surgical excision. In October 1993 he had received surgical excision of hemangiopericytoma on posterior chest wall. For more than 6 years after the operation he was in good condition until a recurrent mass was found on the chest X-ray. The patient was discharged 9 days after the operation and is receiving radiotherapy.

An unusual placentoid bullous lesion of the lung was reported. The patient was a 27-year-old woman with a 1-week history of chest pain and mild dyspnea. Chest radiographic studies showed multiple huge bullae in right upper lobe and variable-sized bullae in middle and lower lobes with collapse. She underwent right pneumonectomy with preoperative impression of bullous lung disease and emphysema. Histopathologically, the most distinctive features were villous structures within bullous airspace, which resembled placetal villi with degeneration.

Congenital radioulnar synostosis can be a disabling state, especially if it is bilateral or fixed hyperpronation. The purpose of this study is to introduce the surgical technique in proximal radioulnar synostosis who needs surgical intervention. Our procedures included excision of synostosis, interposition of muscle flap using brachioradialis, anconeus or extensor carpi ulnaris muscles with vascular pedicle for prevention of re-ankylosis and biceps transfer to improve supination. From July 1994 to July 1996, we evaluated 8 cases in 6 patients who underwent these procedures. The average age was 7 years and average duration of follow up was 24 months. The fixed forearms with hyperpronation have gained average 40 degrees of range of rotation. Improvement in holding and using small objects, sports activities and daily living activities was observed in all cases. There were no significant complications including re-ankylosis during the follow-up periods. In conclusion, surgical treatment of congenital radioulnar synostosis with these procedures is a reliable method that prevent re-ankylosis with providing forearm rotation.

We reviewed radiographs of 11 patients with 17 total knee replacement arthroplasty(TKRA) cases. These patients had a residual flexion contracture over 20 degree after TKRA that corrected spontaneously during follow-up. The mean age of patients was 46.5 years(range, from twenty nine to sixty six). Seven patients were bilateral cases and all knees were cases of rheumatoid arthritis. The mean preoperative flex- ion contracture was 53.8 and immediately postoperative contracture was 23.5. The remaining flexion contracture after TKRA was completely corrected during follow-up period in all cases. We measured the distance from upper margin of tibial components to a certain point on the fibula. This point is on a line perpendicular to long axis of the tibia, drawn from a certain point on the fibula. This dis- tance was measured on postoperative radiographs and radiographs with improved flexion contracture, and the differences calculated. There was no significant difference between the two distances. Although the number of cases are small, we conclude that flexion contracture might be corrected to the extent of 20-30 degree by soft tissue stretching rather than bone subsidence.
