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.

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.

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.

Metastatic pulmonary calcification refers to calcium deposition in the normal pulmonary parenchyma and this deposition is secondary to abnormal calcium metabolism. The most common radiologic manifestation consists of poorly-defined nodular opacities that are mainly seen in the upper lung zone. We present here a case of metastatic pulmonary calcification that manifested as atypical, dense, calcium deposition in airspaces within the previously existing consolidation in the bilateral lower lobes, and this process was accelerated by pneumonia-complicated sepsis in a patient with hypercalcemia that was due to hyperparathyroidism.

OBJECTIVES: The aims of this study were to determine the total fluoride concentration and bioavailable fluoride concentration in different toothpastes, based on a newly suggested method by the International Organization for Standardization (ISO), and to compare the measured concentrations with the concentrations written on the packaging. METHODS: The concentrations of total fluoride (TF) and bioavailable fluoride (BF) were measured in six toothpastes. For the TF measurement, 1 g of each toothpaste was mixed with dipotassium hydrogen phosphate (K2HPO4), and hydrogen chloride (HCl) was placed. After 24 hours, the samples were centrifuged and total ionic strength adjustment buffer (TISAB) solution was added. For the BF measurement, the toothpaste was mixed with K2HPO4 for only 1 minute. The samples were centrifuged, and then HCl was placed and allowed to stand for 24 hours. The TISAB solution was added subsequently. The concentration of fluoride ions was measured using a fluoride ion-selective electrode and calculated against a standard curve. RESULTS: The six toothpastes were composed of different fluoride compounds and abrasives. The measured TF concentration ranged from 624.99 ppm to 1,353.00 ppm, and the similarity to the declared fluoride concentration ranged from 53.48% to 93.31%. The measured BF concentration ranged from 587.61 ppm to 1,360.05 ppm, and the similarity to the expected fluoride concentration ranged from 41.97% to 93.80%. Two samples were clearly separated when the samples were centrifuged, whereas the remaining four samples had unclear supernatants. The clearly separated toothpastes (i.e., toothpastes 5 and 6) had BF concentrations that were similar to or lower than the declared fluoride concentrations and the measured TF concentrations. However, the unclearly separated toothpastes showed inconsistent relationships between the measured TF and BF concentrations. CONCLUSIONS: The measured TF and BF concentrations of the six toothpastes did not reach the expected fluoride concentration. This finding resulted from the different compositions and forms of the toothpastes. Therefore, the properties of toothpastes need to be considered when measuring their fluoride concentrations.

Thromboembolic complications (TECs) are clinically important sequelae of nephrotic syndrome (NS). The incidence of TECs in children is approximately 2%-5%. The veins are the most commonly affected sites, particularly the deep veins in the legs, the inferior vena cava, the superior vena cava, and the renal veins. Arterial thrombosis, which is less common, typically occurs in the cerebral, pulmonary, and femoral arteries, and is associated with the use of steroids and diuretics. Popliteal artery thrombosis in children has been described in cases of traumatic dissection, osteochondroma, Mycoplasma pneumoniae infection, and fibromuscular dysplasia. We report of a 33-month-old girl with bilateral iliac and popliteal arterial thrombosis associated with steroid-resistant NS due to focal segmental glomerulosclerosis. Her treatment involved thrombectomy and intravenous heparinization, followed by oral warfarin for 8 months. Herein, we report a rare case of spontaneous iliac and popliteal arterial thrombosis in a young child with NS.
