PURPOSE: To determine the accuracy of MRI on postoperative pain syndrome (POPS), including early complications such as hematoma or infection. MATERIALS AND METHODS: Of the 54 patients with the POPS, we analyzed pre-operative MRI findings compared with operative findings on 39 patients, excluding nonunion, instability, metal failure and pseudarthrosis, who underwent an operation for POPS from December 1994 to June 1997. There were 25 men (64.1%) and 14 women (35.9%), aged from 16 to 68 years (average 44.5 years). They were divided into 5 subgroups and calculated for sensitivity, specificity and positive predictability. RESULTS: MRI accuracy in recurred disc was 84%, scar adhesion, recurred or developed stenosis, infection and hematoma was 100% for each overall accuracy of MRI was 93%. Average interval of reoperation in POPS was 3.2 years. In 21 cases (53.8%), symptoms persisted without pain-free interval after first operation. CONCLUSIONS: Early complications, including hematoma and infection, are easily detected with MRI. Especially if patient complains of severe leg pain or neurologic deficit, MRI is a good diagnostic tool. MRI is a useful method for evaluation of most cases of POPS, but it is limited in evaluating recurred disc or scar adhesion only in T1, T2 weighted image. Therefore, Gd-DTPA enhancement is necessary for an accurate diagnosis.

Aneurysms of the ascending aorta are relatively uncommon disorders which are located in ascending portion of the thoracic aorta. The commenest cause of aneurysms of the ascending aorta is arteriosclerosis, but syphilis, marfan syndrome, cystic medial necrosis, trauma, and aging of the aorta must also be noted as causes. We report a case with a aneurysm of the ascending aorta, 23 years old female, who was performed the open heart surgery because of ventricular septal defect with aortic insufficiency about 10 years ago.

The patient was a 35 year old woman complaining of non tender erythematous nodule on the left nipple for 2 years. Histopathologic findings showed focal acanthosis and extension of epithelium into some of the superficial ductal structures. In the dermis, the tubules were lined by a peripheral layer of cuboidal cells and a inner layer of columnar cells. The papillary projections of the luminal cells into the lumen also were shown. In the upper dermis, we could find the keratin cysta. She was treated with a simple excision of the nipple and subareolar tissue.

Median nerve injury after elbow dislocation is uncommon. The diagnosis of median nerve entrapment is often delayed. Median nerve paralysis is caused by entrapment within the elbow joint. If median nerve paralysis occurs following elbow dislocation or if it occurs following closed reduction, entrapment should be suspected. Optimal management of this problem consists of early surgical exploration and decompression. We report a case of a child who had entrapment of the median nerve in the elbow joint after closed reduction of posterior dislocation with fracture of the medial epicondyle. The diagnosis was made ten weeks after injury at surgical exploration. This case showed a characteristic radiologic sign in the anteroposterior radiograph. We released the entrapped median nerve with a successful result.

BACKGROUND: The present investigation was undertaken to evaluate the neuroprotective effect of etomidate against kainic acid (KA) induced neurotoxicity in rats by using the immunoreactivity of heat shock protein-70 (HSP-70) and the acid-fuchsin stain. METHODS: Administration of etomidate (20 mg/kg, I.P.) was performed in sequence; first being just one hour after a KA (10 mg/kg, I.P.) injection, then three more times at one hour intervals. Neuronal damages in the hippocampus were evaluated by using the acid-fuchsin stain to detect cell death and HSP-70 induction as an index of cell injury at 24 h after the administration of KA. RESULTS: HSP-70 induction and acid fuchsin positive neurons were increased in the CA1 and CA3 regions of the hippocampus after a KA injection but significantly decreased by an injection of etomidate (P < 0.01). CONCLUSIONS: These results suggest that the etomidate has a potential effect on the protection of neurons against KA-induced neurotoxicity.

Citrullinemia type I is an urea cycle defect caused by mutations in the argininosuccinate synthetase (ASS1) gene. We report a novel argininosuccinate synthetase gene mutation in a Korean family with type I citrullinemia. Metabolic evaluation revealed significant hyperammonemia. Amino acid/acylcarnitine screening using tandem mass spectrometry showed high level of citrulline. Plasma amino acid analysis showed high level of citrulline and the urine organic acid analysis showed makedly increased level of orotic acid. To confirm diagnosis of citrullinemia we did mutation analysis of the ASS1 gene. The patient was found to have mutations of c.689G>C (p.G230A) and c.892G>A (p.E298K), which were new types of argininosuccinate synthetase gene mutation have never been reported in Korea. We report a novel case of argininosuccinate synthetase 1 gene mutation and suggest that the gene study to the family members is necessary to carry out when a patient is diagnosed as citrullinemia.
