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 spite of vigorous efforts to enhance appropriateness of blood usage in surgery, it is recognized that there are still not a few overuse and misuse of blood products in Korean hospitals. To assure appropriate use of blood, continuous monitoring and controlfling blood orders, particularly for surgical operations, should be implemented. The indicator of 'ratio of crossmatching to transfusion' (C/T ratio) has been focalized on in this regard. The authors investigated C/T ratio for eight hospitals, evenly distributed in their geographical location as well as size. Only elective surgeries operated from March 1 to May 31, 1995 were included for analysis. Standardized survey format was distributed, and retrospective reviews of medical records were performed by volunteer surveyors from each hospital after two sessions of pre- survey education. The results were as follows. Average C/T ratio, for all hospitals and all surgeries, was 1.76. Differences in C/T ratio by sex, months, clinical departments, blood components were not significant. However, the ratio showed increasing tendency with ages. The C/T ratio on the average was not higher, compared with the recommended guideline. However, due to study' s limitations ini standardization of survey method and verification of data, we could not conclude that current status of appropriateness of blood use is satisfactory. In addition, to pervasively use the C/T ratio as a quality indicator for blood use management, supplementary measures, such as standardization of data, should be adopted.

The Persistent auditory hallucinations may provoke the uncomfortable feeling and can be dangerous according to its contents in treatment-resistant schizophrenic patients. Previous functional brain imaging studies on auditory hallucinations reported that the abnormal activations of the normal auditory pathway and the activations of the left upper temporal lobe were found while patients were hallucinating voices. Base on the these findings, we treated a female schizophrenic patient with persistent auditory hallucinations that were treatment-refractory with rTMS and the ECT continuously while she was on the drug treatment. The total amount of pulses applied in each trial ranged from 240 to 1000pulses. Fourteen trials were done and resulted in decrease by 30% in the subject severity of auditory hallucinations and the improvement of the affect. Two weeks after the completion of rTMS trials, nine trials of ECT were administered which leaded to complete disappearance of auditory hallucinations. This result suggest that ECT is more effective than rTMS in treating persistent auditory hallucinations in treatment-resistant schizophrenic patients.

OBJECTIVE: Major depression is known to have immunologic dysfunctions, the recent studies revealed that cytokines including Il-6 and IL-1beta were increased in patients with major depression. Since molecular genetic methods have been progressed, this study was to investigate the relationship between major depression and immunologic aspects by analyzing polymorphism of IL-10 gene. METHOD: 92 patients with major depression were included and data of 146 normal controls obtained from the Catholic Hemopoietic Stem Cell Information Bank of Korea were used in this study. DNA was extracted from whole blood, thereafter amplified by polymerase chain reaction, and digested by Mae III. After that procedure, we obtained and assessed RFLP of two alleles, IL-10T and IL-10C. All data were analyzed by chi2 test. RESULTS: 1) There were no significant difference in genotype frequencies of IL-10*T/T, IL-10*T/C, and IL-10*C/C between major depression patients group and control group. 2) There were no significant difference in allelic frequencies of IL-10*T and IL-10*C between major depression patients group and control group. CONCLUSION: We did not verified the differences in frequencies of IL-10*T/IL-10*C gene between the major depression patients group and control group, respectively. But the results of this study do not declare that the IL-10 gene has no association with major depression. We do suggest that further systematic studies including various clinical variables should be conducted.

There had been few reports of arachnoid cyst accompanying psychiaric disturbance and no report treated with low-dose resperidone administration. We report a patient, developed first-transient psychotic episode considered to be provoked by an arachnoid cyst, responsive to risperidone, which was found in the middle cranial fossa as follows. A 57-year-old man was admitted by suddenly developed headache, auditory hallucination, delusion of persecution and, an arachnoid cyst in the anteromedial aspect of middle cranial fossa was found on MRI after admission. The psychotic episode was first to him and he was also negative to other clinical evaluation including endocrine abnormality, his psychotic symptom was suspected to be induced by arachnoid cyst and was well controlled to low-dose risperidone administration. He left hospital free from psychotic symptoms on 14 hospital days.

Among various soft tissue tumors, extraskeletal chondroma is a rare benign cartilaginous tumor most frequently found in the hands, adjacent to periarticular tissue. We recently experienced a case of extraskeletal chondroma in a 47-year-old woman. The skin lesion showed a slowly-growing, solitary nodule on the dorsal aspect of her foot, causing pain and tenderness. An excisional biopsy was undertaken, revealing a well-encapsulated subcutaneous nodule which was mainly composed of mature hyaline cartilage.

Staphylococci are known to produce catalase, but there have been a few case reports of catalase-negative Staphylococcus aureus. The present report describes the first case of catalase-negative S. aureus associated with vaselinoma to our knowledge. We isolated a catalase-negative strain of S. aureus from a penile wound of a 35-year-old man who injected with vaseline into his penis 9 months ago. Colony morphology and biochemical reactions of the strain were typical of S. aureus except for catalase. The patient was diagnosed as having vaselinoma with wound infection and was successfully treated by the surgical removal of the vaseline granuloma and the administration of appropriate antibiotics. Catalase-negative S. aureus is considered to be a very rare variant of S. aureus. To date the number of reported cases of catalase-negative S. aureus is very few, so further studies need to be conducted to evaluate its clinical relation.

We report a 46-year-old woman with primary biliary cirrhosis (PBC) presenting with Sjogren's syndrome and systemic mononuclear inflammatory vasculopathy. Biopsy specimens of sural nerve showed findings consistent with vasculitic neuropathy. Perivascular inflammatory mononuclear cell infiltration was observed on muscle biopsy specimen. The findings of abdominal computed tomography and brain magnetic resonance imaging were suggestive of vasculitis. Clinical manifestations and radiologic findings were improved after high dose prednisolone therapy.
