Primary renal lymphoma is a controversial entity and extremely rare disease, possibly due to the fact that the kidney is one of the extranodal organs usually not containing lymphoid tissue. It is unclear if this conditions can be diagnosed preoperatively with imaging studies. In most cases the diagnosis is made after removal or biopsy of a kidney for suspected primary renal tumor or at autopsy. Treatment usually consists of surgery and chemotherapy with or without radiation therapy and the prognosis is poor. We report a case of primary renal lymphoma presenting with fever in a 13-month- old boy who was treated with surgical intervention and combination chemotherapy.

Acute coronary closure occurs 2-10% during the procedure of PTCA, 50-80% of those events are in the catheterization room. The causes of acute coronary closure are mainly due to dissection, thrombosis or spasm. We recently experienced a case of acute left main coronary artery closure due to guiding catheter induced embolization in the 56 year-old female, unstable angina patient complicated by diabetes mellitus and chronic renal failure. The patient received cardiopulmonary resuscitation shortly after acute closure because of cardiac arrest. During the resuscitation, we performed PTCA at the site of acute closure. The blood pressure maintained normaly after successful recanalization. And then we inserted IABP(intraaortic balloon pump) balloon and did PTCA of original stenosis sites. The patient removed IABP 24 hours later and discharged a month later without complication.

Currently the evaluations of upper extremity motion have relied on a task-oriented approach to gain an accurate clinical picture of the functional capacities. As it is, an adequate and objective system to estimate upper extremity function is yet to be developed. Authors used the virtual reality motion analysis system(VRMAS) which was developed by us for the purpose of investigating the kinematics of upper extremity motion during drinking a cup of water. Four healthy male adult subjects were recruited from the hospital personnels. After each subject sat down on a chair resting against the backrest in a neutral position, in front of a table he was instructed to drink the content of the cup from the table. The data was analized and showed the following results. While drinking, the hand movements were smooth and linear. There were six distinct stages during drinking a cup of water; a reaching for the cup(stage 1), picking up the cup and carrying the cup to the mouth(stage 2), extending neck and drinking from the cup(stage 3), flexing neck(stage 4), replacing the cup to the table(stage 5), and returning to the start position(stage 6). During the stage 1 and 2, of all joint motions, the shoulder adduction and elbow flexion were most prominent. The stage 3 showed the most complex movements in shoulder flexion, forearm pronation, and wrist extension which were simultaneous. Remaining stages were the reversal of the first three stages. We could observe the ranges of motion of neck, shoulder, elbow, and wrist joint as well as the relationships of these joints at the same time. In conclusion, VRMAS could be a very useful evaluation tool for the upper extremity motion and for obtaining the kinematic data from the upper extremity motion analysis.

Purpose: The concept of hidden hearing loss can explain the discrepancy between a listener’s perception of hearing ability and hearing evaluation using pure tone audiograms. This study investigated the utility of the suprathreshold auditory brainstem response (ABR) for the evaluation of hidden hearing loss in noise-exposed ear with normal audiograms. Materials and Methods: A total of 15 patients (24 ears) with normal auditory thresholds and normal distortion product otoacoustic emissions were included in a retrospective analysis of medical records of 80 patients presenting with histories of acute noise exposure. The control group included 12 subjects (24 ears) with normal audiograms and no history of noise exposure. Pure tone audiometry and suprathreshold ABR testing at 90 dB peSPL were performed. The amplitudes and latencies of ABR waves I and V were compared between the noise-exposed and control groups. Results: We found no significant difference in the wave I or V amplitude, or the wave I/V ratio, between the two groups. The latencies of ABR wave I, V, and I–V interpeak interval were compared, and no significant intergroup difference was observed. Conclusion The results suggest that either hidden hearing loss may not be significant in this cohort of patients with acute noise exposure history, or the possible damage by noise exposure is not reflected in the ABRs. Further studies are needed to inquire about the role of ABR in identification of hidden hearing loss.

OBJECTIVE: The purpose of this study is to investigate the interactions between prognostic factors and functional outcome of patients surgically treated posterior fossa epidural hematomas. METHODS: Between 1992 and 2001, twenty patients were surgically treated for the posterior fossa epidural hematomas. The medical records and radiologic findings of the patients were reviewed retrospectively. Information on potential prognostic factors was collected, and then univariate analysis was performed to determine significant prognostic factors. RESULTS: Initial Glasgow Coma Scale scores of 12 patients were 13 or better. Occipital skull fractures were found in 16 cases(80%). The degree of 4th ventricle compression measured on computed tomography scan. Seven cases showed total obliteration, nine cases showed partial obliteration and four cases showed normal. Eighteen patients experienced good or moderate outcomes(Glasgow Outcome Scale scores of 4 or 5). Functional outcome showed a significant correlation with Glasgow Coma Scale score, degree of 4th ventricle compression(p<.05). CONCLUSION: If poor initial consciousness level and severe 4th ventricle compression are noted, early and aggressive treatment are required. Although clinical progression of posterior fossa epidural hematoma is silent and slow, the deterioration might be sudden and quick to become fatal if not promptly treated.

Monoclonal gammopathies are associated with a wide range of renal diseases, including cast nephropathy, light chain amyloidosis, monoclonal immunoglobulin deposition diseases, and so on. We describe seven cases of monoclonal gammopathies involving kidney. The mean age was 61.6+/-3.6 years and male to female ratio was 1:1.3. Among 7 patients, diagnoses were cast nephropathy with light chain deposition disease, two light chain deposition diseases, three light chain amyloidosis and light chain deposition disease with light chain amyloidosis. Two cases were monoclonal gammopathy of undetermined significance and three cases were multiple myeloma in five cases underwent bone marrow biopsy. It showed that renal function was severly decreased in light chain deposition disease. It is clear that monoclonal gammopathies show various renal disease and clinical course in our cases. It is necessary to do renal biospy for adequate diagnosis and treatment even to old patients suspecting monoclonal gammopathy.

PURPOSE: The purpose of this study was to evaluate the MR findings of calvarial eosinophilic granuloma. MATERIALS AND METHODS: We reviewed the MR imaging studies of nine patients [M:F=3:6, aged 6 -35 (mean, 20.5) years] with pathologically proven eosinophilic granuloma in the calvaria. The findings were evaluated for involvement of the diploic space, changes in adjacent bone marrow, distinction of the transitional zone, pattern of bone destruction, signal intensity and contrast enhancement of the tumor, and contrast enhancement of the adjacent dura. RESULTS: All lesions involved the diploic space, showed no change in adjacent bone marrow, and had a distinct transitional zone. In most (8/9) cases there was asymmetric bony destruction. On T1-weighted images, signal intensities of the tumors varied, while on T2-weighted images, hyperintensity was observed in seven cases, isointensity in one, and hypointensity in one. After the administration of contrast material, enhancement was homogeneous in four cases and inhomogeneous in five. Enhancement of the adjacent dura was demonstrated in all nine cases. CONCLUSION: The characteristic MR findings of calvarial eosinophilic granuloma are variable signal intensity on T1WI, high signal intensity on T2WI, and marked contrast enhancement; in addition, there is a distinct transitional zone, asymmetrical bony destruction, and associated dural enhancement.

BACKGROUND: The purpose of this study was to investigate the clinical and electro physiologic characteristics of patients with multiple accessory pathways. Recently as endocardial mapping has become more and more accurate, multiple accessory pathways which were considered to be rare in the past, have become more commonly reported in patients with Wolff-Parkinson-White syndrome. METHODS: From February 1993 to June 2000, there were a total of 452 patients, who were confirmed to have accessary pathway mediated-tachyarrhythmias diagnosed by electrophysiologic study. Among those, 19 patients had multiple accessory pathways, and were enrolled in this study. RESULTS: Among the 19 patients, thirteen patients were male and six were female, and their mean age was 36.5+/-16.17 years. All patients had 2 accessory pathways. The distribution of the location of the accessory pathways was at the left free wall (71.1%), right free wall (18.4%) and posteroseptal wall (10.5%). The most common combination pattern was the left free wall and left free wall (57.9%) and the most common anatomical areas were the left lateral wall and left posterior wall (36.8%). The success rate of the catheter ablation was 84.2% (16/19). The recurrence rate after the radiofrequency catheter ablation was 31.3% (5/16) and the most common recurrence site was left free wall (60.0%, 3/5). CONCLUSION: These results indicated that the clinical and electrophysiologic characteristics of the multiple accessory pathway patients with WPW syndrome in our study were similar to those of western countries.
