Hepatoblastoma (HB) is a rare embryonic malignant tumor of the liver. Most morphological studies on HB have limited to the histological characteristics and only 3 cases of HB have been described in the cytology literature. We present 2 cases of HB occurring in children aged 1 year and 3 years, respectively. The distinctive cytologic features of fine needle aspiration of HB were clusters of tumor cells showing acinar and trabecular pattern, smaller tumor cells with a high nuclear-cytopalsmic ratio and hyperchromatic nuclei having prominent nucleoli, and the presence of extramedullary hematopoiesis and osteoid material. These features were also found in the cell block and the biopsy specimen, and appeared very useful in the differentiation of HB from hepatocellular carcinoma.

In an attempt to investigate the pattern of the urinary acidification process in the Korean, the urinary excretion of phosphate, ammonia, and the titratable acid were measured in 20 medical students (A group) and in 15 psychiatric patients (B group) under regular Korean diets, while the effects of high protein diets on them were studied in 4 subjects. In addition, TmPO4 was also determined in 11 subjects. The urinary excretions of phosphate, titratable acid, and ammonia under regular Korean diets were markedly lower as compared to those of the Europeans. However, there was no difference in the plasma concentration of phosphate between the Korean and the European. Upon administration of high protein diets, the urinary excretions of phosphate and titratable acid increased while the urine pH and the ammonia excretion were little affected. Thus, the correlations between urinary nitrogen and titratable acidity were 0.50 and 0.65, respective1y, showing a linear relationship. However, the correlation between urinary nitrogen and ammonia excretion was slight. The value of TmPO4 ranged from 74 to 355 muM/min with the mean of 193 muM/min, which is considerably higher than that of the European. On the basis of these findings, the overall pattern of the urinary acidification processes in the Korean is discussed.

Changes in the urinary tract associated with prolapse uteri have been known for a long time. However, women who have a prolapse uteri are often free of symptoms. When symptoms are present they are above all, urinary tract infection, difficulties in emptying the bladder, increased frequency of micturition, stress incontinence, and ureteral obstruction. We reviewed 82 patients who had prolapse uteri of grade II and III in order to evaluate the effects of prolapse uteri to the urinary tract. There were 5 patients (6.1%) who had urinary tract infection and urine culture revealed the growth of E. coli in 3 of them. Only 1 patient (1.2%) had high blood urea nitrogen. 51 (62.2%) out of 82 patients showed voiding problems (frequency, voiding difficulty, stress incontinence) and 53 (64.6%) out of 82 patients had cystocele of several degrees, but there was no difference between the degree of prolapse uteri and both voiding problems and cystocele. Vaginal hysterectomy with anterior and posterior colpoperineorraphy was performed in 68 (88. 3%) out of 77 patients who underwent surgical treatment by gynecologists, and in 22 (91.7%) out of 24 patients who showed difficult urination, their symptoms were improved immediately after surgery. Bladder neck suspension was performed simultaneously in 3 patients who showed stress urinary incontinence with prolapse uteri. Intravenous pyelography or abdominal ultrasonography was performed to evaluate accompanied ureteral obstruction in 8 patients who had severe cystocele. In 5 patients, upper tract deteriorations were noted. Bilateral hydroureteronephrosis was found in 3 patient, unilateral lower ureteral dilatation in 1 patient, and severe parenchymal damage in 1 patient. In conclusion, we believe that urologist should participate in managing those patients who have prolapse uteri to improve their voiding problems and prevent upper urinary tract deterioration.
