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.

Nine surgically proven congenital absence of gallbladder (CAGB) cases were reviewed. All of them had one or more kinds of biliary symptom. Tests such as abdominal ultrasonography, intravenous or oral cholecystography and even endoscopic retrograde cholangiography not only failed to predict CAGB but misleadingly indicated other similar conditions. Only the abdominal computed tomography (CT), performed on one patient, enabled the accurate diagnosis of CAGB. All the patients underwent abdominal exploration, and CAGB was confirmed by the meticulous dissection of the entire extrahepatic biliary tree and the operative cholangiography. Five patients had concomitant biliary pathologies responsible for their symptoms, but four patients had isolated CAGB. CAGB is a rarely encountered condition for a clinician, but extensive diagnostic work-ups including abdominal CT should be performed in all situations where CAGB is suspected. Thus unnecessary exploration can be avoided in the isolated CAGB case.

Biliary ascariasis is a rare complication of intestinal ascaris infestation. Retrograde migration of the adult worm through the papilla of Vater causes biliary colic, and may give rise to pancreatic and biliary obstruction, choledocholithiasis, cholecystitis, cholangitis, hemobilia, and if the worm lodges in intrahepatic bile ducts, to liver absceases. In the past, treatment of biliary ascariasis has usually involved the direct removal of ascaris throagh a surgical choledochatomy and subsequent saline lavage of the common duct through an indwelling T tube. Recently, the worm in the bile duct can be seen by ERCP and it can be removed during the endoscopic procedure. A 55-year-old woman with intermittent colicky right upper quadrant abdominal pain was admitted to out hospital. Abdominai sonogram disclosed an echogenic structure within a mildly dilated common bile duct and a high ehogenic structure with acoustic shadowing in the distal common bile duct(CBD), which suggests a CBD stone. ERCP after obtaining the sonogram revealed a thick, long, linear, smooth filling defect in the CBD with a distal CBD stone. A distal CBD stone was removed by sphinctetotomy and lithotripsy, then we directly extracted ascaris with a tripod forcep without any complication.

Superior oblique myokymia refers to a disorder characterized by involuntary torsional and vertical oscillation of one eye, lasting several seconds to minutes with an irregular interval. We report a 44-year-old woman with superior oblique myokymia, who presented with quivering sensation and oscillopsia of the left eye. Magnetic resonance imaging of the brain was normal. The involuntary eye movement and oscillopsia responded to carbamazepine.
