We experienced a case of mitral incompetence due to rupture of anterolateral papillary muscle in a 56-year-old male who complained of abdominal pain and mild dyspnea after being struck by car. Clinical manifestation immediately following injury was minimal, but heart failure progressed rapidly 3 days after injury. Echocardiopraphic evaluation revealed ruptured anterolateral papillary muscle and severe mitral regurgitation on color flow imaging. There was no evidence of coronary artery disease on coronary angiography. Operation revealed that the haed of anterolateral papillary muscle was torn out of its insertion. Mitral valve replacement with mechanical prosthesis was performed on the 50th day after injury.

Malignant fibrous histiocytoma(MFH) of the maxilla is a rare malignant bone tumor. Seven percents of all MFH occur in the head and neck. Approximately 12% of these tumors occur in the maxilla. Local recurrence or distant metastasis was reported in 55% of cases of maxillary MFH. The mean survival time of 30 months was reported from a review of 14 MFHs in he masxilla, mandible and oral soft tissues. MFH of the maxilla is best treated surgically but radical neck dissection dose not appear to be indicated unless there is clinical evidence of lymph node metastases. Although the use of radiation therapy for head and neck MFH has not been studied for a series of cases, individual cases of regression or histological change have been reported. Other authors have reported numbers of cases who received radiation therapy without benefit. Response to combination chemotherapy has been reported in 33% of 23 patients with recurrent or metastatic MFH. We report here a case of MFH occurring in the maxilla with a review of literature about the clinical behavior and treatment of these lesions.

PURPOSE: We reviewed 5 years worth of experience with peritoneal drainage and dialysis in infants who underwent open heart surgery. The aim of this study was to investigate the effect of peritoneal drainage and peritoneal dialysis on fluid balance and several parameters of intensive care. METHODS: Six(10%) of 60 consecutive infants who underwent open heart surgery required peritoneal dialysis during peritoneal drainage. Simple peritoneal drainage was performed in the remaining 54 infants. The silicone rubber peritoneal dialysis catheter was inserted into the center of abdominal cavity just after operation, and subsequent peritoneal drainage was maintained during intensive care. RESULTS: Mean age of the study group was 0.48+/-0.21 years(M: F=32: 28). Early postoperative mortality amang the infants with congenital heart disease was 1.6%. Total amount of output was 7.0+/-2.28mL/kg/hr, urine output 5.14+/-2.9lmL/kg/hr, pleural fluid 0.80+/-0.5lmL/kg/hr, and peritoneal fluid 1.20+/-0.90mL/kg/hr. The ratio of output to intake(O/I) was 1.06. None of the complications required early termination of peritoneal drainage or peritoneal dialysis. Hemodynamics and pulmonary function were maintained steadily during postoperative intensive care. CONCLUSION: The early institution of peritoneal drainage and peritoneal dialysis in infants with congenital heart disease after cardiac operations not only removes fluid, thus easing fluid restriction, but may also improve cardiopulmonary function.

OBJECTIVE: Pfirrmann disc grade is a useful scoring tool for evaluating disc degeneration, but normal values according to aging process has not been elucidated. This study was conducted to identify the prevalence and pattern of whole spine disc degeneration according to ages and gender differences. METHODS: Total 653 patients (336 male and 317 female patients, 48.1±58.7 years old) who took whole spine magnetic resonance images were enrolled in this study. There were 19 cases in their 2nd decades and 74 cases in 3rd decades, 141 cases in 4th decades, 129 cases in 5th decades, 139 cases in 6th decades, and 93 cases in 7th decades, 58 cases in over 8th decades. Pfirrmann disc grades were measured according to sex and ages by 2 neurosurgeons that were blind to this study. RESULTS: All spinal disc degeneration grades were correlated with ageing. The Pfirrmann disc grades of degeneration in all spine levels showed the statistically significant difference according to the ages (p < 0.001). The common Pfirrmann disc grades according to the ages were grade 3 among 2nd to 5th decades, and grade 4 was more common than 6th decades. The lower cervical level (C2–3 to C4–5) and lumbar level (L1–2 to L5–S1) were happened relatively early severe disc degeneration compared to other levels. The intersexual differences were increased after 6th decades. CONCLUSION: Disc degeneration is natural course after one’s 2nd decades. And its incidence and grade were increased with age, and more affected by sexual difference after 6th decades.

Ameloblastoma is a rare epithelial tumor of the jaw, comprising approximately 1% of all tumors and cysts of odontogenic origin. The tumor has been the subject of much controversy and discussion. Ameloblastoma is slow growing, locally invasive, and has a high rate of local recurrence, but rarely metastasizes. The neoplasm has been considered radioresistant, so it has been treated with surgery primarily except some cases. Recently it is suggested that ameloblastoma is radiosensitive, so radiation therapy (RT) would be used in addition to or, in certain cases, in place of surgery. We report these two cases which were referred to the Department of Therapeutic Radiology for deciding the need of postoperative RT, because ameloblastoma is rare and has been known to be radioresistant. Postoperative RT was given to one of these two patients.

Core decompression is still widely used in avascular necrosis of the femoral head but the results are unpredictable and the indications are not settled yet. The reparative process of the decompressed femoral head is poorly understood. Seven cases in 5 patients were undertaken THRA following failed decompression and these were studied for the radiological and pathological changes of the core tracts. The lesions of failed cases were involved more than 1/3 of femoral head on MRI and all cases were stage II A or B. The extent of the necrotic area in MRI was enlarged with crack, sclerosis and sometimes gas collection. Depression of the subchondral plates were also observed. Capillary ingrowth or neovascularization was not found at all and there were only fibrosis, inflammatory response and foreign body reactions.
