Internuclear ophthalmoplegia is a conjugated gaze disorder characterized by impaired adduction on the side of a lesion involving the medial longitudinal fasciculus with dissociated nystagmus of the other abducting eye. Six patients with INO (who had clinical cerebrovascular diseases) underwent MR imaging and the results were as follows: 1. The MLF lesions were identified by MR imaging in 5 cases 2. The ratio of unilateral INO to bilateral INO was 5:1 3. The nature of lesions was infarction in 4 cases and hemorrhage in 1 case 4. The sites of MLE lesion were in the midbrain in 4 cases and in the pons in 1 case 5. All 5 cases of INO identified by MR imaging had other lesion sites in addition to MLE lesion.

Echinococcus granulosus, an intestinal tapeworm of dogs and other canids, infects humans in its larval stage and causes human echinococcosis or hydatid disease. In the Republic of Korea, 31 parasite-proven human echinococcosis cases have been reported, most of which were imported from the Middle East. We recently examined a 61-year-old Korean man who had a large cystic mass in his liver. ELISA was negative for tissue parasitic infections, including echinococcosis, cysticercosis, paragonimiasis, and sparganosis. The patient underwent surgery to remove the cyst, and the resected cyst was processed histopathologically for microscopic examinations. In sectioned cyst tissue, necrotizing protoscolices with disintegrated hooklets of E. granulosus were found. In some areas, only freed, fragmented hooklets were detected. The patient had traveled to western and central Europe in 1996, and had no other history of overseas travel. We report our patient as a hepatic echinococcosis case which was probably imported from Europe.

We studied the best parameter to differentiate preoperatively between malignant ovarian tumors and benign ovarian tumors. From January 1988 to December 1992, 244 patients of ovarian tumor were treated with surgery at Chonnarn University Hospital. Patients diagnosed as malignancy by histopathology were 26.2%(64 patients), As the diagnostic pararnetar, we used age, ultrasonography, tumor markers, CT or MRI. The results were obtained as follows: 1. The predictive value of ultrasonographic examination for ovarian cancer was 73.1%. 2. The predictive value of seren CA-125 level for ovarian cancer was 69.1%. 3. The predictive value of combination af ultrasonographic examination and serum CA 125 level for ovarian cancer was 90%. 4. The predictive value of combination of the age older than 40 years, ultrasonographic examination and serum CA-125 level for warian canrer was 92.3%. 5. The predictive value of comhination of three tumor markers(CA-125, CEA and CA 72-4), ultrasonographic examination, CT and MRI for ovarian cancer was 94.6%. Finally, we could preaperatively most exactly differentiate between malignant ovarian tumors and benign ovarian tumors by use of age, three tumor markers(CA-125, CEA and CA 72-4) and ultrsonography, CT or MRI.

PURPOSE: We analyzed the survival and failure patterns of cervix cancer patients treated with irradiation alone to evaluate our treatment method and to compare with the others. METHODS AND MATERIALS: Two hundred and twenty cervical cancer patients, Stage IB, IIA, and IIB who completed the planned treatment between May 1987 and December 1991 were analyzed retrospectively. The Stage IB patients were restaged to the Stage IB1 and IB2 by the recently revised FIGO classification. Patients were treated with a combination of external irradiation and the intracavitary brachytherapy. Determination of the tumor control was done at the time of 6 months postirradiation. The follow-up time was ranged from 3 to 115 months and the mean was 62 months and the follow-up rate was 93.6%(206/220). RESULTS: The overall 5-year survival rate of Stage IB1(N=50), IB2(N=15), IIA(N=58), and IIB(N=97) was 94%, 87%, 69%, and 56%, respectively. In the univariate analysis of prognostic factors,stage(0.00), initial Hg level (p=0.00), initial TA-4(tumor-associated) antigen level(p=0.02), initial CEA level(p=0.02), barrel-shaped tumor(p=0.02), whole cervical involvement (0.00), pelvic lymphadenopathy(LAP) in CT(p=0.04), and post-irradiation adjuvant chemotherapy(p=0.00) were statistically significant in survival analysis. In a while, multivariate analysis showed that the stage was the most powerful prognostic indicator and the post-irradiation chemotherapy factor also showed the statistical significance. The overall local control rate was 81% and by the stage, 100% in Stage IB1, 86.7% in Stage IB2, 84.5% in Stage IIA, and 68.1% in Stage IIB, respectively. The overall tumor recurrence rate was 15.5%(27/174) and by the stage, 8%(4/50) in Stage IB1, 0%(0/13) in Stage IB2, 22.4%(11/49) in Stage IIA, and 19.4%(12/62) in Stage IIB, respectively. CONCLUSIONS: We obtained the similar treatment results to the other's ones in early stage cervical cancer patients. But in Stage IIB, the local control rate was lower than that of the other institutes and also the survival was poorer. So it seems to be necessary to reevaluate the treatment method in advanced cervical cancer patients.

PURPOSE: The mortality rate of neonatal sepsis has been decreased, however, the incidence has not significantly decreased because of increased invasive procedures. This study was designed to make guidelines for choosing antibiotics by analyzing the causative microorganisms and their antibiotics sensitivity test according to the onset of neonatal sepsis. METHODS: One hundred seven cases of culture proven sepsis in 89 patients admitted to the NICU of Chonnam University Hospital from Jan. 2000 to Dec. 2004, were enrolled. By reviewing the medical records, clinical data, laboratory findings, causative organisms and their antibiotics sensitivity, and mortality were analyzed. RESULTS: The incidence of neonatal sepsis was 1.7 percent and more prevalent in premature and low birth weight infants. 85.4 percent of neonatal sepsis was late onset. Almost all microorganisms(92.9 percent) were gram-positive in early onset, however, two thirds were gram-positive and one third were gram-negative and Candida in late onset. Gram-negative organisms and Candida were more prevalent in patients who had central line. Gram-positive organisms were sensitive to vancomycin, teicoplanin, and gram-negative were sensitive to imipenem, and cefotaxime. CONCLUSION: Neonatal sepsis was more prevalent in premature and low birth weight infants. More than 90 percent were gram-positive in early onset, however, one third was gram-negative and Candida in late onset. The first choice of antibiotics were a combination of third generation cephalosporin and clindamycin in early onset, and third generation cephalosporin and glycopeptide in late onset. If there is no response to antibiotics treatment, the use of antifungal agents should be considered.

We report a case of thymic hyperplasia accompanied by pericardial lipomatosis and right facial hemihypertrophy in an 8-year-old boy. On imaging studies, the hyperplastic thymus had prominent curvilinear and nodular fatty areas simulating a fat-containing anterior mediastinal mass, which is an unusual finding in children. To our knowledge, this is the first report on a child with a combination of thymic hyperplasia, pericardial lipomatosis, and right facial hemihypertrophy. The radiologic findings are presented with a brief discussion.

PURPOSE: To assess the value of MR imaging in the diagnosis of medial collateral ligament injury of the knee, we used MR imaging to evaluate the characteristic findings in MCL tears and the frequency of associated knee joint injury. MATERIALS AND METHODS: We retrospectively reviewed 26 patients within four weeks of MCL injury, analysed MR findings and correlated them with surgical findings. We evaluated discontinuity, heterogeneous signal intensityof MCL, thin band- like low signal intensity at MCL, facial edema, loss of clear demarcation of adjacent fat andalso combined bone injury, meniscus injury and other ligament injury. RESULTS: Complete MCL tears were present in 14 patients and partial tears in 12. Complete tears showed discontinuity of MCL, fascial edema and loss of clear demarcation from adjacent fat in 11 patients (79%) ; proximal MCL tears are more common than distal tears. Partial tears showed thin band-like low signal intensity within MCL, fascial edema and loss of clear demarcation fromadjacent fat in seven patients (58%) ; all patients with MCL injury showed fascial edema ; in 12 patients there was loss of clear demarcation from adjacent fat. We could not, however, distinguish between complete tears and partial tears when MCL showed heterogeneous high signal intensity. Combined bone injury in MCL tears was found in eight patients (62%) ; the most common sites of this were the lateral femoral condyle and lateral tibial plateau. There was associated injury involving other ligaments(ACL:50%; PCL: 27%). Combined meniscus injury in MCL tearswas present in 17 patients and the most common meniscus site (50%) is the posterior horn of the medial meniscus. CONCLUSION: Complete MCL tears showed discontinuity of MCL and partial tears showed a thin band-like low signal intensity within MCL. All patients with MCL injury showed fascial edema, and loss of clear demarcation fromadjacent fat. Various other injuries combine with MCL tears. MR imaging is therefore useful in the evaluation ofmedial collateral ligament injury and associated knee joint injury.

Sodium picosulfate/magnesium citrate (Picolight Powder), which is used as a bowel preparation for the colon and the rectum, can cause a severe electrolyte imbalance like hyponatremia. When hyponatremia gets severe or occurs rapidly, it can lead to death due to associated complications. We have experienced a case of hyponatremia associated with seizure and loss of consciousness in a 76-year-old woman, who took sodium picosulfate/magnesium citrate as a bowel preparation for colonoscopy. She was taking thiazide and synthroid for the treatment of hypertension and hypothyroidism, respectively, and she had other underlying medical conditions such as a history of seizure and dementia. Following the diagnosis of hyponatremia, we used an intravenous injection of 3% NaCl to normalize the sodium level in her serum, and her associated symptoms soon disappeared.
