Juvenile granulosa cell tumor is rare but one of the common congenital testicular neoplasms. Although histological features are typical of its ovarian counterpart, testicular juvenile granulosa cell tumor has a distinctly different clinical presentation. We report a case of juvenile granulosa cell tumor arising in the cryptochid testis of a 4-day-old newborn. A 6 5 5 cm sized multilocular cyst containing thick, mucinous fluid was found in the peritoneal cavity. The external surface of the cyst was smooth and the septae were relatively thin. The cyst consisted of numerous mucin-filled, cystic follicles lined by cells having vacuolated cytoplasm and round to oval dark nuclei without grooves. Cells resembling granulosa cells of an ovarian follicle were also observed in the intervening stroma forming irregular solid nests.

Since the introduction of Rh-immune globulin in 1968, the incidence of Rh D hemolytic disease of the newborn(HDN) had become markedly reduced but in the contrary the HDN by minor blood group antibodies has become increased relatively. As anti-E is the most common minor blood group antibody identified in antenatal serology and because of the frequency of E-negative people in Korea is ranged from 38.8% to 50.3%, the probability of HDN caused by anti-E is expected relatively high. We had experienced antenatal therapy for a E-isoimmunized pregnant woman, who has the history of one previous stillbirth and one neonatal death. In addition to above obstetric history, she had a history of blood transfusion, in which she was given 7 units of whole blood during the operation of brain cyst 7 years ago, before her marriage. Therapeutic plasma exchanges were repeated from the 22nd to 25th weaks of gestation. During the period a mean volume of 350mL plasma volume was exchanged on average twice a week. After the period, therapeutic plasma exchange procedure was failed because of unsuccessful vascular access. So that we gave her intravenous immunoglobulin(IVIG), 0.4gm/kg for 5 days, and two intrauterine transfusion were given at 25th and 27th weeks of gestation to relief from grave HDN. The maximal antiglobulin titer of anti-E during the gestation period was 1:32. In spite of intensive therapy as above mentioned, she was delivered a severely hydropic fetus weighing 1,900g at 29th weeks of gestation under Cesarean section. The neonate died 2 days after the birth with severe erythroblastosis fetalis and disseminated intravascular coagulation (DIC). Even though we could not save the baby, we report this experience as a reviewable case of antenatal treatment modalities for Rh immunization and the serious consequence of blood transfusion before marriage.

BACKGROUNDS: Gamma band oscillatory activity is considered to be related to congnitive functions and illustrates that the concept of event-related oscillations bridges the gap between single neurons and neural assemblies. An event-related gamma oscillation is the time - locked responses of specific frequency, and can be identified by computing the amplitude frequency characteristics of the averaged event-related potentials(ERPs) after stimulation. OBJECTIVES: We purposed to present experimental paradigm to investigate @-band oscillation activities from the recording of ERPs by using auditory oddball paradigm and investigate the difference of @-band activity between schizophrenia and normal controls. METHODS: The ERPs resulting from auditory stimuli with oddball paradigm in a group of schizophrenics(n=11) and also a group of age-, sex- and handedness matched normal controls, were recorded by 128 channel EEG. The @-band oscillatory activities were calculated by using time-frequency wavelet decomposition of the signal between 20 and 80Hz. The @-band oscillatory activities of both groups were compared by t-test. RESULTS: The @-band oscillatory of the leads Fz,Gz and Pz of both groups were represented well in the time - frequency maps. Significant increases of the @-band activity in normal controls compared with schizophrenics were observed around 160 msec. 350msec. and 800 msec after stimulation. CONCLUSIONS: Our results suggested that the increment in @-band oscillatory activity during cognitive operations and decreased @-band activity in schizophrenics may be associated with the cognitive dysfunctions and the pathophyiology of the schizophrenia.

OBJECTIVE: To investigate the influence of associated medical diseases and complications on functional improvement after in-patient through stroke rehabilitation. METHOD: We performed a retrospective analysis on medical records of 183 stroke patients who had admitted to the department of rehabilitation medicine. Functional Independence Measure (FIM), Modified Barthel Index (MBI) at admission and discharge were used to assess the functional status. We investigated medical diseases, such as hypertension, diabetes, myocardial infarct, atrial fibrillation osteoarthritis, rheumatoid arthritis, previous history of stroke and complications such as dementia, post-stroke depression, central post-stroke pain, complex regional pain syndrome, neglect and aphasia. RESULTS: Post-stroke patients with myocardial infarct, atrial fibrillation, osteoarthritis, dementia, aphasia and neglect significantly showed lower gain of FIM and MBI, lower FIM and MBI efficacy during inpatient rehabilitation compared to without those (p<0.05). However, hypertension, diabetes, previous history of stroke, post-stroke depression, rheumatoid arthritis, central post-stroke pain and complex regional pain syndrome did not significantly influence on gain and efficacy of FIM and MBI (p>0.05). Total numbers of associated medical diseases and complications negatively affect on FIM and MBI efficacy (p<0.05). CONCLUSION: Therefore, it may be important to early detect and manage associated medical diseases and complications in post-stroke patients during rehabilitation, which improve the overall functional recovery of the patients.

BACKGROUND: Pleural eosinophilia is rare and commonly considered to be an indicator of good prognosis. The diagnostic significance of eosinophilic pleural effusions remains controversial despite a century of observation and discussion. This study was conducted to assess the prevalence of eosinophilia in 446 consecutive samples of pleural fluid, to review the cause of eosinophilic pleural effusion and to determine whether the presence of eosinophils increases the likehood of benign conditions. METHOD: A retrospective analysis was performed upon patients that underwent first thoracentesis due to pleural effusion between January 1999 and December 1999. RESULTS: Eosinophilic pleural effusions were identified in 24 of the 446 patients (5.4%). Malignancy, parapneumonic effusion and tuberculosis were determined the major causes of pleural effusion (80.6%). Malignancy was diagnosed as frequently in eosinophilic effusions as in non-eosinophilic effusions (54.2% vs 50.5%, p=0.725). No difference was found in the prevalence of eosinophilic and non-eosinophilic effusion according to the etiology. The mean blood eosinophil ratio in patients with eosinophilic pleural effusion was 5.4% and no significant correlation existed between the blood and pleural eosinophilic count. CONCLUSION: Pleural eosinophilia is not helpful for differentiating benign and malignant etiology and is not related with blood eosinophilia or repeated tapping.

PURPOSE: The aim of this study was to identify the predictive factors in the early laboratory findings for cardiac sequelae in Kawasaki disease(KD). METHODES: A retrospective review of the records was conducted of all children with KD who were admitted to the Ulsan Dongkang General Hospital, Masan Samsung Hospital, and Gyeongsang National University Hospital between January 1995 and December 1999. We analyzed and compared the early laboratory findings between the patients with and without coronary artery dilatation. RESULTS: A total of 981 patients were divided into two groups : 826 patients(84.3%) with normal coronary artery and 155 patients(15.7%) with coronary artery dilatation. Age and sex were not significantly different between the two groups. The mean serum C-reactive protein(CRP) in the coronary artery dilatation group and in the normal coronary artery group were 5.0 mg/dl(+/-5.3) and 4.1 mg/dl(+/-5.0), respectively, with a significant difference(P<0.05), whereas the other early laboratory findings had no difference between the groups. CONCLUSION: This study shows that the early serum CRP was higher in patients with KD who had coronary artery dilatation than in those with normal coronary artery. There may be a strong possibility of cardiac sequelae at a high level of serum CRP. However, the cut-off value of serum CRP could not be determined for the prediction of cardiac sequelae in patients with KD.

PURPOSE: Warthin's tumor is a slow growing tumor found exclusively either in the parotid gland or the periparotid lymph nodes. Although surgical resection is the treatment of choice, the extent of surgery which is most beneficial has remained contraversial. We performed a comparative study of the results between enucleation and parotidectomy groups to evaluate the effectiveness of the enucleation procedure for the surgical management of parotid Warthins tumor. METHODS: Between January 1981 and July 2001, 74 patients underwent surgical resection of parotid Warthin's tumor. We reviewed the clinicopathological characteristics retrospectively and compared the operation time, postoperative complication rate, duration of postoperative hospital stay and recurrence between the enucleation group and the parotidectomy group. RESULTS: The mean age was 57.0 years (19~86 years) and the male to female ratio was 5.7: 1. The majority of the tumors were situated in the lower region of the superficial lobe (89.2%). Bilateral simultaneous involvements of the parotid gland was found in 5 patients (6.8%) and therefore a total of 79 parotid glands were involved. Four (5.4%) of the 79 parotid glands featured multifocal tumors of two or three lumps. Tumor sizes varied from 0.5 to 13.0 cm with a mean diameter of 3.5 cm. Of the 74 patients, 51 (68.9%) were diagnosed preoperatively or perioperatively by means of CT scans, ultrasound, 99m-Tc. scan, fine needle aspiration cytology or intraoperative frozen section biopsy. Of the 79 glands, 46 underwent a superficial (n=39), partial (n=2) or total (n=5) parotidectomy, while enucleation was performed for the remaining 33 cases with single Warthin's tumor. Only one case of recurrence was identified during the follow up period. However the operation time, the postoperative complication rate, and the duration of postoperative hospital stay were all significantly reduced in the enucleation group (P<0.05). CONCLUSION: The enucleation procedure may represent a safe and appropriate surgical method for patients with single Warthin's tumor that is diagnosed preoperatively.

Aplastic anemia is a rare side-effect associated with ticlopidine therapy. We report one case of severe aplastic anemia developed after the use of ticlopidine. A 72-year-old woman took ticlopidine at 500 mg/day to prevent a secondary stroke. Forty days after starting ticlopidine, she developed general weakness and nausea. She showed pancytopenia and was diagnosed as aplastic anemia, confirmed by bone marrow examination. Twelve days after the withdrwal of ticlopidine, the hematologic parameters improved. Physicians are reminded that complete blood cell counts and white blood cell count differentials should be monitored every 2 weeks in ticlopidine users during the first 3 months of treatment.
