We anlized CT of 29 cases of various orbital disease in pediatric age group. Diagnoses were confirmed byeither operation or direct ophthalmoscopy. The patients were examined during the period of last 3 years. Theresults were as follows: 1. Of 29 cases, 21 were male and 8 were female, and the age ranged from 20 days to 15years. 2. Intraorbital tumors were 13 cases consisting of 7 retinoblastoma, 3 pseudotumor, and 1 each ofcongenital teratoma, cavernous lymphanngioma, and optic glioma, Of remaining 16 cases, 6 had orbital fracture, 5persistent hyperplastic primary viterous(PHPV), 3 vitreous opacity, and 2 primary glaucoma. 3. The CT findings ofthe retinoblastoma were a lobulated or oval soft tissue mass denisty (40-60HU) extending into the vitreous wtihoutsignificant enhancement on postcontrast scan. Of 7 cases, 4 had calcifications within the tumors. The extraglobalextension of the tumor was shown in 2 patients demonstrating markedly thickened sclera with enhancement anddilated optic nerve. 4. There were 5 patients with PHPV having a history of white pupil since birth, and all wereaffected unilateraly. Four patients had vitreous opacity and 3 of those showed either linear or branchingtree-like densities within the vitreous on the postcontrast scan. Another one had a lobulated increased densityprotruding into the vitreous which was difficult to differenciate from the similar finding of retinoblastoma.Remaining one case demonstrated a deformed and decreased density in the lesional lens without chaneg in thedensity of the vitreous. This was confirmed to be caused by persistence of the embryonic hyaloid artery attachedto the posterior capsule of the lens. 5. There were 3 patients with vitreous opacity and 2 of them were due toretinal detachment and 1 was caused by retrolental fibroplasia. The CT findings of retinal detachement werehomogenous or heterogenous opacities in the vitreous. In a case of retrolental fibroplasia, irregular, band-likedensity was seen along the posterior wall of the globe bilaterally. 6. Two cases of primary glaucoma showed largeglobe with a widened anterior chamber. 7. Among 6 cases of orbital fractures, 5 were blow-out fracture. Theblow-out fractures showed fractures of the medial orbital wall or orbital floor with herniated intraorbitalcontents into the neighboring ethmoid or maxillary sinus.

The pregnancy-associated breast cancer is one of the most common malignacy developing during the period of pregnancy and occupies 1-2% of the all breast cancer patients. It is not easy to make an appropriate diagnosis due to difficulty of physical examination of the breast and limitation of proper diagnostic modalities. The pregnancy-associated breast cancer had been reported to portend an extremely poor outcome. But recent studies have found no difference in survival between general breast cancer and pregnancy-associated brest cancer. The treatment of choice is the modified radical mastectomy and adjuvant chemotherapy of needed. The authors report two patients of breast cancer diagnosed and treated during pregnancy with review of literature.

OBJECTIVE: As the number of North Korean adolescent refugees drastically increased in South Korea, there is a growing interest in them. Our study was conducted to evaluate the mental health of the North Korean adolescent refugees residing in South Korea. METHODS: The subjects of this study were 102 North Korean adolescent refugees in Hangyeore middle and high School, the public educational institution for the North Korean adolescent refugees residing in South Korea, and 766 general adolescents in the same region. The Korean version of Child Behavior Check List (K-CBCL) standardized in South Korea was employed as the mental health evaluation tool. RESULTS: The adolescent refugees group showed a significantly different score with that of the normal control group in the K-CBCL subscales for sociality (t=29.67, p=0.000), academic performance (t=17.79, p=0.000), total social function (t=35.52, p=0.000), social withdrawal (t=18.01, p=0.000), somatic symptoms (t=28.85, p=0.000), depression/anxiety (t=13.08, p=0.000), thought problems (t=6.24, p=0.013), attention problems (t=4.14, p=0.042), internalized problems (t=26.54, p=0.000) and total problems (t=5.23, p=0.022). CONCLUSION: The mental health of the North Korean adolescent refugees was severe particularly in internalized problems when compared with that of the general adolescents in South Korea. This result indicates the need for interest in not only the behavior of the North Korean adolescent refugees but also their emotional problem.

BACKGROUND/AIMS: The principle of the rapid urease test is the assessment of the color change of the pH indicator, phenol red, by ammonium and bicarbonate ions which were produced by the urease. We modified a conventional rapid urease test, and quantified H. pylori infection by measuring the change of spectrophotometric absorbance. METHODS: 202 patients with upper gastrointestinal symptoms were endoscopically examined and three biopsies were performed in each antrum and fundus. Two biopsy specimens were stained with Giemsa and scored from 0 to 4 according to the distribution of bacteria by the Wyatt method. Another specimen was used for the quantitative rapid urease test. The tissue was incubated in a cuvette containing 10% of urea solution and phenol red at 37C. We measured optical densities in 550 nm at 5 min, 10 min, 15 min, 30 min, 1 hrs, 2 hrs, 4 hrs and 24 hrs time points.

The demand for intravenous sedated upper gastrointestianl endoscopy is currently increasing steeply. Despite this trend, patient status complication due to this procedure is largerly neglected by most physicians. Recently, in three patients, mouthpiece fragment were left within the patients' body after intravenous sedated upper gastrointestinal endoscopy. They were transferred to our institution for the removal of the fragment. The patients complained of an uneasy sensation from within their body, around their necks and chests. After conducting therapeutic endoscopy, the fragment could be located around the distal part of their esophagus and within their stomach. The fragment were removed successfully by using snare in two patients, and by using forceps in another patient.

Pagonimus Westmani, occuring as an important human infestation of the lung, is widely distributed in the Far East ; Korea, Japan, China and the Philippines. Since Otani found the parasites for the first time in the human brain in 1887, it has been established that cerebral infestation occurs with the highest frequency among extrapulmonary involvement. In 0.8 to 25 percent of patients infested with the lung flukes cerebral paragonimiasis may be developed. The larvae may procedure arachnoiditis, abscess, fibrous cystic lesions and granulomas in the brain. Based on a review of the literatures and upon the 7 cases of cerebral paragonimiasis which have been observed by the authors at the National Medical Center, Seoul, Korea, the following points are stressed. 1) Males had a significantly higher prevalence than females. Cerebral paragonimiasis was most commonly found in young adults(16 to 25yrs). 2) Clinically the patients with cerebral involvement were characterized by Jacksonian type of epilepsy, headache and visual disturbance. Mental deterioration, hemiplegia, hemihypesthesia, homonymous hemianopsia and optic atrophy were the five major signs. 3) The patients having symptoms for less than 6 months developed mild leukocytosis in many cases. All the cases of cerebral paragonimiasis revealed positive reaction in the intradermal tests with purified antigens of P. Westermani. 4) On skull films multiple round or oval cystic calcification was diagnostic value for cerebral paragonimiasis. On angiogram vascular staining and abnormal vessels were not disclosed. On pneumoencephalogram subcortical atrophy or filling defect of the ventricle may be showed. 5) The predilection area of the granuloma and fibrous cystic mass were the occipital, posterior parietal and posterior temporal lobes. 6) The patients with chronic stabilized cerebral paragonimiasis. having intractable symptoms and signs, could not be improved with Bithionol treatment. But headache, vomiting, visual disturbance, facial weakness and especially intractable seizure were improved in our cases treated with surgical operation.

Gallbladder carcinoma is an uncommon neoplasm, and hemobilia caused by this disease is rare. We present a case of hemobilia in a patient with gallbladder carcinoma, which was recognized at forward duodenoscopy. A 42-year-old man visited our hospital due to intermmittent right upper quadrant pain. Duodenoscopy revealed blood clots with bile juice around the ampulla of Vater and the second portion of the duodenum. Endoscopic ultrasonography for the gallbladder showed a dumbell-shaped mass with a homogenous internal echogenicity on the body of the gallbladder. MR cholangiography showed a lobulated mass with low-signal intensity in the T1-weighted and T2-weighted images. Subsequently, laparoscopic cholecystectomy with regional lymph node dissection was performed, and adenocarcinoma was confirmed.

BACKGROUND/AIMS: To determine the treatment modalities and the prognosis of a patient with liver cirrhosis, quantitative estimation of liver function is important. We assessed the Child-Pugh score (CPS), the common method as a severity index for the cirrhosis, the Promthombin, gamma GT, and Apolipoprotein A1 (PGA) index and model for end-stage liver disease (MELD) score. The purpose of this study was to evaluate the correlation between these indices in the patients with cirrhosis only and hepatocellular carcinoma (PHC), according to underlying causes (HBV and alcohol). METHODS: We reviewed medical records of 339 cirrhotic patients with/without hepatocellular carcinoma and divided patient groups by disease and underlying cause: cirrhosis caused by alcohol; LC-Al, cirrhosis caused by HBV; LC-B, hepatocellular carcinoma with cirrhosis caused by alcohol; HCC-Al, hepatocellular carcinoma with cirrhosis caused by HBV; HCC-B. We assessed the CPS, PGA index and MELD score and calculated the correlation coefficient between these scores. RESULTS: Among the total of 339 patients, 201 patients were diagnosed on the liver cirrhosis only, and 138 patients on the hepatocellular carcinoma with cirrhosis. In each groups, mean score values were not significantly different in CPS, PGA index and MELD score. The correlation of CPS, PGA index and MELD score in all groups, except for the correlation of PGA index and MELD score in HCC-Al group, was significantly positive (p<0.05). Compared to correlation coefficients between three indices, the patients with cirrhosis only had higher tendencies than the patients with hepatocellular carcinoma. The patients by HBV had higher tendencies than by alcohol. CONCLUSIONS: The correlations between CPS, PGA index and MELD score showed significantly positive correlations in the patients with liver cirrhosis only and hepatocellular carcinoma with cirrhosis (except in HCC-Al group). The patients with cirrhosis only had higher correlation coefficients than the patients with PHC and the patients by HBV had higher than by alcohol.

PURPOSE: The purpose of this study is to illustrate MR patterns of signal intensity of proximal femur in normal subjects according to the age distribution. METHOD AND MATERIAL: Tl-weighted MR images of the proximal femur in 125 subjects, aged 13 days to 25 years, were retrospectively analyzed. Age distribution was classified to 4 groups;below 4 months, 5 months to 4 years, 5 years to 14 years, and 15 years to 25 years. RESULTS: By the age of 4 months, the non-ossified femoral epiphysis was seen as intermediate-signal-intensity cartilage. At 5 months-4 years, the ossified fernoral capital epiphysis was seen within intermediate-signal-intensity cartilage and appeared as decreased or increased signal-intensity red or yellow marrow surrounded by a rim of low-signal-intensity cortical bone. At 5-14 years, the ossified femoral capital and greater trochanteric epiphysis were seen within the intermediate-signal-intensity cartilage and appeared as decreased or increased signal-intensity red or yellow marrow. At 15-25 years, the proximal metaphyseal marrow showed increased signal intensity. Four patterns of the metaphyseal marrow were recognized by Ricci et al. The frequency of pattern la progressively decreased with age. Pattern 2 and 3 were visible in the 15-25 years age group. CONCLUSION: An understanding of the spectrum of normal age-related change of the proximal femoral cartilage and marrow patterns serves as the foundation for interpretation of proximal femur pathologies.

BACKGOUND: The present study was undertaken to determine the effect of remifentanil on the bispectral index (BIS) during intubation under TIVA (total intravenous anesthesia) using propofol. METHODS: In this prospective, randomized, double-blind study, 80 healthy patients aged 18~60 years undergoing elective surgery were investigated. Anesthesia was induced using propofol (target effect-site concentration 4microgram/ml). After the loss of consciousness, rocuronium (0.9 mg/kg) and remifentanil was infused. The patients in the R group were infused with remifentanil using a target effect-site concentration of 4 ng/ml, and patients in the P group were infused with saline. The BIS value, mean arterial pressure (MAP) and heart rate (HR) were measured before induction, before remifentanil infusion and before and after tracheal intubation. RESULTS: The BIS value remained constant after intubation in the two groups. The MAP and HR increased significantly after intubation in the two groups, but the degree of increase of MAP and HR was less in group R than in group P significantly. CONCLUSIONS: We suggest that the BIS value is not affected by the administration of remifentanil during intubation under TIVA using propofol.
