Experiments were conducted to define the optimal constituents of culture medium and atmospheric condition for growth of Campylobacter pylori. Two clinical isolates were streaked onto various media, incubated in two different atmospheric conditions (microaerophilic condition and carbon dioxide incubator), and growth was assessed semiquantitatively according to relative colony size and extent of growth through the streak. The growth obtained on Campy media, composed of GC agar base plus 1% hemoglobin, 0.2% activated charcoal, 1% IsoVitaleX, vancomycin 6mg /L nalidixic acid 20mg/L and amphotercin 2 mg/L, was used as reference. Our conclusions were as follows: Tryptic soy agar base was not acceptable for the growth of C. pylori. The organism grew in both atmospheric conditions, but generally showed a scantier growth in the carbon dioxide incubator than under the microaerophilic condition, however GC agar containing 1% hemoglobin and 0.2% activated charcoal supported well the growth of C. pylori in the carbon dioxide incubator. The authors have found that the GC agar base supplemented with 1% hemoglobin and 0.2% charcoal was the most satisfactory medium and a microaerophilic condition was optimal atmospheric condition for the growth of Campylobacter pylori in this study.

Ganglioneruroblastoma and neuroblastoma are among commonest types of childhood malignancy and a number of unique paraneoplastic syndromes have associated with both localized and disseminated neuroblastoma. The coincidence of neuroblastoma and myoclonic encephalopathy or other paraneoplastic syndromes occurs relatively rare, and therefore, failure to recognize this association could result in delays in both diagnosis and treatment, and the result could prove to be unfortunately fatal. The mechanism which underlies the remote damaging effect of neural crest tumor, especially neuroblastoma, on the nervous system resulting in myoclonic encephalopathy is by no means clear. In addition the nature and the extent of the pathologic lesion are inconsistent. We experienced a case of myoclonic encephalopathy associated with an occult mediastinal ganglioneuroblastoma in a 22-month-old girl who was hospitalized for inability to walk without support and tilting of the head to the left side. She became increasingly ataxic, and during the hospitalization myoclonic jerks of upper extremities and head along with chaotic, rapidly flickering, multidirectional spontaneous eye movements, were noted. Laboratory data included normal complete blood count, urinalysis, BUN and creatinine, electrolytes and bone marrow. Chest X-ray and chest CT revealed a relatively well marginated right posterior mediastinal mass. In a 24 hours urine excretion test, VMA and catecholamines were increased. Over the next 2 weeks, a surgical exploration revealed a right posterior mediastinal mass. Microscopically the mass proved to be a ganglioneuroblastoma, extending to right innominate artery and right axillary lymph nodes. Within 2 weeks after the surgery, radiotherapy (2,400 rads) and chemotherapy (CTX, DTIC, VCR) were started, but corticosteroid was not used. She has been free of tumor and abnormal neurological systemic symptoms and signs for 1 1/2 year since the completion of chemotherapy. In the 3 1/2 years follow-up period, her neurologic symptoms has completely resolved by the completion of 2 years chemotherapy. We report a case of mycoclonic encephalopathy associated with hidden ganglioneuroblastoma in 22-month-old girl.

An ossifying fibromyxoid tumor of soft parts is a rare, recently described, fibro-osseous neoplasm of uncertain histogenesis. It occurs most frequently within the subcutis or skeletal muscle of the extremities. Its biologic behavior is generally regarded as benign with at worst a locally aggressive clinical course. But, atypical and malignant variants have been recently reported. Herein we report a case of a benign ossifying fibromyxoid tumor which occurred in the left upper back of 41-year-old man. The tumor is composed of uniformly round or polygonal cells arranged in cords or nests which are separated by myxoid and hyalinzed fibrous matrix and associated with irregular bony trabeculae. The tumor cells are strong positive for vimentin. Ultrastructural findings and a review of literatures are added.

A study to evaluate the diagnostic significance of M. pneumoniae Infection by measurements of cold agglutinin and antimycoplasma antibody titers is performed with 191 pediatric patients who have visited Yeungnam University Hospital during the period through January to July, 1987. Forty eight of 191 cases made follow up tests feasible. The results obtained are as follows: 1. It is necessary to perform routine combined measurements of cold agglutinin and antimycoplasma antibody titers for the all pediatric pneumonia caser since a large proportion of pneumonia in children is caused by M. pneumonia. 2. For the diagnosis of M. pneumoniae Infection, measurements of cold agglutinin titer alone seems to be less significant than to check both cold agglutinin and antimycoplasma antibody titers. 3. The measurement of antimycoplasma antibody titer appeared to be more specific than cold agglutinin test in the diagnosis of M. pneumoniae Infection. 4. The present study urges the necessity of follow up study of cold agglutinin and antimycoplasma antibody titer for those who initially presented with normal titers in both tests, but are clinically suspected for M. pneumoniae Infection.

Body fluid Lactate dehydrogenase and its isoenzyme Measurement was performed in 132 patients: 8 cases with peritonitis, 21 cases with malignant ascites, 43 cases with liver cirrhosis, 48 cases with tuberculous pleuritis, 12 cases with malignant pleural effusion respectively. Body fluid protein and glucose contents, red blood cell counts, white blood cell counts, cytologic examination were also performed as a comparative study. The results were as follows: 1. Measurement of total LD and protein amount could differentiate between transudate and exudates in the ascitic fluids. 2. In the malignant exudate of ascites and pleural fluid, the activity of LD2 isoenzyme was statistically increased compared with that of inflammatory exudates and the activity of LD4 isoenzyme was also incereased compared with that of serum (P<0.05). 3. The inflammatory exudates of pleural fluid and ascites demonstrated the increase of LD5 isoenzyme activity statistically compared with that of serum and malignant exudates (P<0.05). 4. A difference of total LD activity between malignant ascites and inflammatory ascites was significant statistically, while this was not observed in the pleural exudate. 5. Total LD and LD5 isoenzyme activity didn't correlated with the number of white blood cells in the exudate.

Antimicrobial susceptibility of the bacterial strains isolated from clinical specimens during the period from June, 1983 to June, 1986 in Yeungnam Medical Center was studied and the following results were obtained. 1. Staphylococcus aureus was highly susceptible to cephalothin and its susceptibility to methicillin was gradually reduced. 2. Streptococcus strains except enterococcus were generally susceptible to penicillin, while most enterococci were susceptible to only ampicillin. 3. Gram-negative rods including Escherichia coli were highly susceptible to amikacin and tobramycin. 4. Serratia were generally less susceptible to the amtimicrobials tested than other Enterobacteriaceae. Among them, Serratia marcescens showed the highest susceptibility to amikacin and chloramphenicol. 5. Pseudomonas aeruginosa revealed the highest susceptibility to amikacin and tobramycin and moderate susceptibility to carbenicillin and gentamycin. 6. Acinetobacter calcoaceticus revealed low susceptibility to most antimicrobials tested, showing only 30% susceptibility to amikacin, tobramycin and gentamycin in 1986.

Intraductal variant of peripheral cholangiocarcinoma is extremely rare. This variant shows intraductal growth and intraluminal extension without any infiltrative growth. The mode of intraductal growth is not known. The prognosis of this variant is better than that of usual cholangiocarcinoma. We report three cases, one of which is associated with Clonorchis sinensis (CS) infection. The tumors were entirely confined within the dilated peripheral tributaries of the intrahepatic bile duct. Microscopically, the tumors were well to moderately well differentiated, with a papillary or a micropapillary growth pattern. Focal clear cytoplasmic change and mucin production were noted. The tumors showed intraductal spreading without any invasion to the liver parenchyme. Mucosal hyperplasia and dysplasia were noted in the adjacent ducts. The authors assume that intraductal cholangiocarcinoma is a distinct subtype, and persistent irritation, such as, CS infection may undergo a malignant transformation through mucosal dysplasia.

PURPOSE: To evaluate the change in multifocal visual evoked potential (mfVEP) in unilateral anisometropic amblyopia before and after occlusion treatment. METHODS: The mfVEP was performed using RETIscan(R) (Roland,Brandenburg, Germany) for patients with unilateral anisometropic amblyopia before and after occlusion treatment. Amplitude and latency values of mfVEP were analyzed according to the field divided by 6 rings or 4 sectors. RESULTS: The each amplitude of values of all 6 rings were not significantly different before treatment (p = 0.077) in amblyopic eyes. However, the value of ring 1 (p = 0.00) was significantly higher than the value of other rings after treatment. In fellow eyes, the values of ring 1 was consistently significantly higher than the value of other rings before (p = 0.014) and after (p = 0.049) occlusion treatment. Additionally, the amplitudes of ring 1 (p = 0.005) and ring 3 (p = 0.007) were significantly increased in amblyopic eyes after occlusion treatment. In fellow eyes, the values of all rings did not change significantly. The analysis of amplitudes with 4 sectors revealed no significant result. The analysis of latencies with 6 rings and 4 sectors revealed no significant result. CONCLUSIONS: The change in amplitude on the central field (ring 1) in amblyopic eyes can be a useful objective monitoring method observing the improvement progress in visual acuity.
