Cystadenoma of the liver is a rare neoplasm. Although many cystadenomas are asymptomatic, symptoms can include abdominal pain, postprandial epigastric discomfort, and nausea. Dramatic changes in hepatic imaging techniques have been helpful for diagnosing cystic lesions of the liver, such as simple cyst, hydatid cyst, cystadenoma, cystadenocarcinoma, and metastatic neuroendocrine tumors. However, it remains difficult to differentiate cystadenoma from cystadenocarcinoma for multiseptated cystic hepatic lesions with papillary projection on computed tomography (CT) and magnetic resonance imaging (MRI). Here we report the case of a 47-year-old woman with several months of postprandial discomfort and abdominal fullness. CT and MRI revealed multiseptated cystic lesions with papillary excrescences. A left hemihepatectomy was performed. Histology showed a benign mucinous cystic tumor with ovarian-like stroma.

Hemorrhagic fever with renal syndrom is an acute febrile disease which is caused by Hantanvirus and several other viruses that belong to the genus Hantavirus. Gl and G2 glycoproteins of Hantanvirus have been thought to be involved in protective immunity against Hantanvirus infection. In this study, the antigenicity of G1 and G2 glycoproteins in cell mediated immune response was investigated. When peripheral blood mononuclear cell fraction from recovered hemorrhagic fever with renal syndrome patient was cultivated with a recombinant protein containing amino-terminal 78 amino acids of G2 glycoprotein, these cells were activated to proliferate and secreted significant amount of interleukin-2 and interferon-r. These results suggest that T cell epitope exists in the amino-terminal region of G2 glycoprotein.

Chymopapain was discovered by Jensen in 1941, and in 1963 Smith demonstrated the chondrolytic properties of chymopapain. Since then, many patients have been injected with this agent. Although there are evidences of neurotoxicity to chymopapain in animals, adverse effects in humans have rarely been reported. We present a case delayed onset of paraplegia after chymopapain chemonucleolysis and review the neurotoxicities to chymopapain.

The study wasdesigned for the evaluation of diagnostic usefulness of standard electro-oculography (EOG) battery in differentiating the vertigo of central origin from that of peripheral one. Twelve patients of definite posterior fossa lesion proved by MRI or CT scan were selected as a central group and fourteen patients of peripheral vestibulopathy as a peripheral group. Using our laboratory standard methods of EOG battery, age-matched normal valuse of bithermal caloric responses(fixation supperssion, vestibular paresis, and directional preponderance) and the gains of pursuit and optokinetic nystagmus were obtained. Abnormal vestibular paresis was found in 21 patients of the peripheral group, but in only one patient of the central. Directional preponderance did not show significant difference between the peripheral and central group (p<0.01). In peripheral group, the fixation suppression index (percent change in slow-phase velocity with visual fixation during the period of maximum intensity of caloric nystagmus) was 56.8+8.3%, p>0.01). However, failure of fixation suppression was noted in eleven patients of central group and its mean value of 92.6+7.3%, which was significant statistical difference compared with peripheral and control group (p<0.01 respectively). Defective suppression of caloric nystagmus was more remarkable when the direction of caloric nystagmus was induced toward the lesion site. Such findings were demonstrated in six patients of eight patients with definits unilateral cerebellar hemispheric lesions. In addition, the gains of pursuit and optokinetic nystagmus were significantly reduced in the patients showing defctive fixation suppression compared with whom showed normal pattern of fixation suppression (p<0.01). Therefore, fixation suppression, vestibular paresis, and the gains of pursuit and optokinetic nystagmus would be useful diagnostic paremeters in differntiaging the vertigo of central origin from that of the peripheral.

It is well known that circulating antibodies are produced by plasma cells derived from B lymphocytes, and T lyphocytes are endowded with the capacity to regulate the type and intensity of virtually all immune responses. Therefore, the measurement of relative and absolute number of lymphocytes in the peripheral blood of myasthenia gravis patients could be of value. We have studied the distribution pattern of lymphocytes and helper/suppressor ratio in the peripheral blood of 28 myasthenic patients in comparison with 10 patients of other neurologic diseases as control by using immunobead method. There was no significant differences between 17 myasthenic patients who had taken only anticholinesterase and control. But in 17 patients who had taken steroid, Helper T lymphocyte was decreased significantly compared to control. Both T lymphocyte and B lymphocyte were also decreased significantly compared to 17 myasthenic patients who had taken only anticholinesterase without steroid therapy. In 3 patients who had undergone thymectomy, there was significant decreases of suppressor T lymphocyte. Plasma exhange as a treatment for myasthenia gravis is currently the subject of clinical interest and research. Clinical response and muscle power measured by using sphygmomanometer were followed in 2 patients in myasthenic crisis and in 4 patients with severe disease refractory to all other treatment modalities, received 4-6 cycles of plasma exchange with Hemonetics 30-S. 2 patients had a recurrence 1.5 and 6 months after first course of plasma exchange respectively, Therefore, they had to take a second course of plasma exchange. The satisfactory increment of muscle power was noticed in 5 out of 6 cases after fourth plasma exchange.

20-40% of cases of acute transverse myelitis are attributed to viral infections, although the specific viral etiology is only rarely identified. We have studied one patient with transverse myelitis in association with acute hepatitis B virus infection. Hepatitis virus should be considered as rare cause of transverse myelitis.
