This study was designed to evaluate the potential applicability of magnetic resonance imaging (MRI) for the diagnosis of acute renal vein thrombosis. Renal vein thrombosis was experimentally induced by surgical ligation of the left renal vein in a total of 21 rabbits. MRI was performed with a 0.5 Tesla superconductive magnetic system. Spin echo technique was used with varying TR and TE parameters. Spin echo images of the rabbit kidney were analysed for morphology and signal intensity. T1 and T2 relaxation times of the renal cortex and medulla were calculated from the images. After venous ligation, kidneys became enlarged. Low signal band along the outer medulla in T2 weighted images were characteristically shown from 1 hour to 3 days after ligation, Changes of cortex to medullar contrast (CMC) values were significant (p<0.05) in T1 - and T2- weighted images of the ligated side. T1 and T2 relaxation times were significantly prolonged (p<0.05) on the ligated side, both in the cortex and medulla from 1 hour to 2 weeks after the ligation, while T2 relaxation time on the contralateral side was significantly prolonged both in the cortex and medulla 2 weeks after venous ligation. The most useful MRI criteria for the diagnosis of renal vein thrombosis were enlarged renal size, and the low signal band along the outer medulla of ligated kidney. The relative intensity difference between cortex and medulla (CMC) in T1-and T2-weighted images, and T1 and T2 relaxation times were suggested to be the useful MR parameters for the diagnosis of acute renal vein thrombosis.

Pseudohypopyon of tumor cells can be found in patient with intraocular tumor. This condition resembles true hypopyon of iridocyclitis. Paracentesis of the anterior chamber may be undertaken to find malignant cells. A 68 year old Korean man with bronchogenic carcinoma was found to have a tumor mass in the root of iris, pseudohypopyon and secondary glaucoma as. Anterior chamber tapping was failed to show tumor cells. Any inflammatory cell was not found in the anterior chamber tapping.

The displaced femoral neck fractures remain a major challenge to orthopaedic surgeons as the elderly population is increasing. Successful union by internal fixation after adequate reduction without avascular necrosis is primary goal since the functional results having own femoral head are much superior to those having prosthetic femoral head, but prosthetic replacement is indicated for some patients with fresh fractures who need early ambulation as well as neglected fractures and failed internal fixations. The early result after prosthetic replacement was known to be very satisfactory but the late complications are becomming the major problem. Authors reviewed 21 cases of the prosthetic replacements for the femoral neck fractures which were followed for more than one year and managed at Fatima Hospital during the years between 1975-1984 and the following results were obtained. 1. The cases were 8 males and 13 females having ages from 42 to 87 years with average 69 years old. 2. The cases were 11 elderly fresh fractures, 6 neglected fractures, 2 failed osteosynthesis and 2 others. 3. Moore and Thompson prosthesis were used and 13 of them were fixed with bone cement. 4. The early result evaluated at 3 months after surgery revealed satisfactory in 90% but the final result at average 3 years and 5 months ranging from 1 year to 6 years and 2 months revealed satisfactory results in 58% 5. There was no significant early post-operative complications. 6. The late complications were 8 cases of acetabular erosions and these were combined with stem loosening in 2, subsidence in 2 and deep infection in 1 case. 7. The late complications started to reveal at about 3 years after surgery and occurred in younger and active patient. 8. The prosthetic replacement for femoral neck fracture is recommended for the inactive patient or the patient with expected activity less than 3 years.

Vitamin D deficient ricket is now a rare disease in the developed countries because of the generally improved nutrition and medical awareness but occasional cases are found in the special susceptible populations. The ricket is characterized pathophysiologically by a failure of the normal mineralization of bones and epiphyseal cartilages and is susceptible to the fractures because of the weakness and increased plasticity of bones. The fractures occurred in rickets are known to be delayed in union but it should be normal if the ricket is effectively treated. Authors reviewed 7 cases of fractures occurred in the vitamin D deficient rickets which were managed at Daegu Fatima Hospital during the years from 1980 to 1986 and the following results were obtained. 1. The cases were 4 boys and 3 girls having ages from 6 to 11 years who were all in the same group of restricted population of poor nutrition. 2. 10 fractures noted in 7 cases including two cases of multiple fractures and a case of refracture and most of the fractures occurred in femurs except for a humerus and a forearm bones. 3. The causes of fractures were uncertain because the definite histories were unable to obtain but any violent trauma was not suggested. 4. The fractures were treated by the usual methods of skin tractions or cast immobilizations and daily doses of 2,000 U. or 5,000 U. of vitamin Dwere given as soon as the rickets are recognized. 5. The normal healing of the fractures and rickets occurred in the cases who were given vitamin D initially when the diagnosis of rickets were made. 6. The healing of fractures were very delayed in 2 cases who were missed to recognize the rickets initially and vitamin D was not given.

The pubic bone is an unusual site for an aneurysmal bone cyst. This case, a 15year old male patient, was diagnosed as an aneurysmal bone cyst in the superior ramus of the right pubic bone. He was treated by complete excision of the superior ramus and on five years follow up no problems were noted in terms of weight bearing as well as hip function or evidence of recurrence.
