BACKGROUND: Hydrops fetalis is defined as abnormal accumulation of serous fluid in two or more fetal compartments, and this malady is known to be associated with various pathologic conditions. METHODS: We collected 149 cases of hydrops fetalis out of 2,312 autopsies, and we tried to elaborate the underlying causes of hydrops fetalis. The diagnosis was based on the material from either antenatal termination or intrauterine death. RESULTS: The relative incidence of hydrops fetalis was 6.44% of all the pediatric autopsies we performed. The gestational age was evenly distributed from 18 to 33 weeks, except for 30 to 31 weeks. There was no sex difference in the incidence of hydrops fetalis. The main causes were cardiovascular diseases (30.9%), cystic hygroma (13.4%), chromosomal anomaly (8.05%), thoracic conditions (7.38%), followed by urinary tract malformation (4.03%), infection (4.03%) and anemia (3.36%). The most common chromosomal anomaly was Turner syndrome and the second one was Down syndrome. CONCLUSION: Since various conditions can be the cause of hydrops fetalis, pathologists should pay attention to elaborate the underlying causes in every single autopsy.

Since early 1980's high resolution ultrasound has been world-widely used for detection of cranial lesions ininfants but not widely used in korea. Authors prospectively analysed ultrasonographic findings of 107 cases whichwere confirmed by CT, autopsy or follow-up studies as supplement. the distribution of 107 cases was intracranialhematoma 40 cases, hydrocephalus 36 cases, hypoxic-ischemic encephalopathy 10 cases, porencephalic cyst 5 cases,cephalhematoma 5 cases, agenesis of corpus callosum 4 cases, medulloblastoma 2 cases and each one case of A-Vmalformation, intraventricular cyst, Dandy Walker cyst, lipoma and hydranecephaly. We could conclude thatneurosonography of infants was very useful and effective method in detection of cranial lesions such asintracranial hematoma, especially germinal matrix hemorrhage or intraventricular hemorrhage in preterm infant,hydrocephalus, hypoxic-ischemic encephalopathy and congenital anomalies.

PURPOSE: It has been known that there are several areas of T2 hyperintensities in normal white matter of brain, such as terminal zones of myelination, ependymitis granularis, ones of posterior internal capsule, and perivascular space. The aim of our study is to demonstrate another region of T2 hyperintensities in normal pediatric age group. MATERIALS AND METHODS: We have studied brain MR for 10 normal volunteers and 35 patients without having intracranial lesions in pediatric age group(3-19 years). RESULTS: In 5 among 45 cases, focal T2 hyperintensities were seen in the parietal periventricular white matter beneath the postcentral gyri. They were noted as poorly defined, 5--10mm sized areas of increased signal intensities on T2 weighted axial images. They were also characterized by bilateral, posteromedially oriented, short band-like or oval areas. Interestingly, they were directly continuous with the T2 hyperintensity of posterior internal capsule. In spite of the relatively high frequency in the pediatric population as in our study, this finding has not been reported in the asymptomatic adults. CONCLUSION: The results show that the bilateral anterior parietal hyperintense areas may be another terminal zones of delayed myelination affecting the parietopontine tract. They should be differentiated from pathologic T2 hyperintensities by their characteristic findings.

Transurethral resection syndrome are caused by the sudden intravascular absorption of large volumes of the irrigating solution which are used during transurethral surgery. It relates to many determining conditions of the patient postoperatively. We studied changes in serum electrolyte following transurethral resection of prostate in 61 patients used 5% Dextrose-Water solution as the irrigant and 46 patients used 1.5% glycine as the irrigant of benign prostatic hypertrophy. We divided the patients into group I and II. group I : those were given 5% Dextrose-Water solution as the irrigant. group II : those were given 1.5% glycine as the irrigant. Change in serum ammonia was obtained in 19 patients of group II. Following results were obtained. 1. Operation time, resected weight and amount of irrigant between group I and II showed no difference, statistically. 2. Serum sodium concentration was decreased in 42 cases of group I (range : 1-20mEq/L, mean : 5.0mEq/L). 3. Serum sodium concentration was decreased in 31 cases of group II (range : 1-18mEq/L, mean : 6.0mEq/L). These changes in serum concentration between group I and group II showed no significant difference, statistically. 4. Change in serum sodium concentration in the group I showed no significant correlation with operation time, resected weight and amount of irrigation. 5. Change in serum sodium concentration in the group II showed no significant correlation with operation time, resected weight and amount of irrigation. 6. Serum ammonia concentration was increased in 10 patients of 19 patients in group II (range : 5-100ug/dl, mean : 42ug/dl).

A fine needle aspiration biopsy specimen of a retroperitoneal mass in a 26-year-old man who had had an orchiectomy for seminoma was submitted for cytologic evaluation. Cytologic features of the specimen included uniform neoplastic cells found singly or in groups of several cells intermingled with lymphocytes in a characteristic foamy, lacelike background. These cells varied from 10 to 20 m in diameter. The nuclei were round to ovoid with fine or reticular chromatin and one or more prominent nucleoli. The poorly defined cytoplasm stained pale-blue or blue with cytoplasmic vacuoles. The cytologic appearance was consistent with seminoma. Documented reports of the cytological appearance of seminoma are rare. The diagnosis of primary gonadal seminoma by fine needle aspiration biopsy is probably not indicated since the treatment of a primary gonadal tumor, regardless of its histogenesis, requires surgical resection. However, fine needle aspiration biopsy is extremely valuable in the diagnosis of extragonadal as well as metastic and recurrent seminoma.
