The diagnosis of ovarian tumor has been mainly dependent on manual pelvic examination and ultrasonography. Butin case of malignant ovarian tumor, CT has more advantages over ultrasonography in assessing anatomic details,relationships to bowel loops, precise extents of tumors and follow-up examinations after surgery. Authors analyzedCT features of 46 cases of patholgocially proven ovarian tumors for recent 4 years at keimyung University DongsanHospital. The results were as follows: 1. The msot common tumor was serous cystadenocarcinoma(9 cases:20%),followed by metastases(8 cases: 17%), mucinous cystadenocarcinoma(7 ases:15%), mucinous cystadenocarcinoma(5cases:11%), teratoma(5 cases:11%), lymphoma(3 cases: 7%) and dysgerminoma(2 cases:4%). 2. The ovarian tumors werevariable in size from 2.5cm to 33cm in diameter. Most of the solid tumors were smaller than 10cm in diameter andmost of the cystic tumors were larger than 10cm in diameter. Usually mucinous tumors were much larger than seroustumors. Mucinous cystadenomas were the largest tumors. 3. Unilateral tumors(left 19,right 13 cases) were morecommon than bilateral tumors(12 cases). Bilateral tumors were seen in serous and mucinous cystadenocarcinoma,metastases and lymphoma. 4. CT features of mucinous cystadenomas were smooth margins and thin wall of the tumormasses and multiloculated cysts with internal septa in all 7 cases. 5. In contrast, CT demonstration ofbilaterality, irregular margin, thick wall, enhancing solid lesions, septal irregularity, adhesion to adjacentstructures, peritoneal/omental implantation, ascites and hydronephrosis were signs suggesting malignancy. CTfeaturs of the serous cystadenocarcinoma were mostly solid to mixed nature(83%), irregular margin(75%), enhancingsolid lesion(67%), papillary growth (75%), internal septa(58%), multilocularity (58%) and calcification (25%) indescending order of frequency. 6. On CT, mucinous cystadenocarcinoma were irregular-marginated, thick-walled,cystic tumors with enhancing solid lesion, septal irregularity and signs of metastasis, although there were somecases having similar features of benign. 7. Among the extrapelvic CT findings of malignant epithelial ovariantumor, peritoneal/omental implants(11 cases:79%) and ascites(10 cases:71%) were the most common, and indistinctuterus(6 cases:43%), bowel adehsion(5 cases:36%) and pseudomyxoma peritonei (2 cases) were descending order offrequency. 8. CT features of teratoma were diagnostic having at least three more of different tissue densitiesamong fat, water, soft tissue and calcific densities. Also there were thick wall (4 cases) and fat-fluid level(1case). 9. In 8 cases of ovarian metastases, there were solid type tumor smaller than 10cm in 4 cases and hugecystic in 2 cases. The site of primary cancer were stomach in 4 cases, colon , cervix, endometrium and unknown ineach one case. 10. In 3 cases of malignant lymphoma, the CT featurs were solid in appearance, smaller than 10cmand accompanied by lymphadenopathy in all cases.

Twenty-four ma1e a1bino rats were chosen at random and divided into two dietary groups: one for control (diet 1) and the other for an experimental diet (diet 2). Diet II consisted of the basal diet supplemented with red pepper powder in increasing amounts from 1.25%, 1.8% and 2.5% to 3.6%. With a red pepper diet at the 2.5% level, there was a significantly lower efficiency of food utilization. (p=0.05) The apparent digestlbility of calcium with red pepper concentrations from 2.5 to 35% was about 13% greater than in tile control diet. Thus red pepper appears to affect the solubility of calcium in the diet. Serum alpha-Carotene and Vitamin A showed a tendency to increase slightly with a red pepper diet. No histological changes in the gastric mucosa cells were observed in rats fed a red pepper diet. Further investigation is required to define the effects of red pepper in different species of animals.

Schizophrenia-like psychiatric symptoms in patients with MELAS are rarely reported. A 34-year-old male was admitted because of visual hallucinations, persecutory delusions and generalized seizure. He also presented with repeated headache, vomiting, and left homonymous hemianopsia. We report a 34-year-male with MELAS presenting psychiatric symptoms before the establishment of the diagnosis by gene analysis.

The maxillary sinus is an anthropological landmark because of difference of volume of maxillary sinus among persons of different ethnic origin. This study was undertaken to provide morphological characteristics of Korean's maxillary sinus. The size and volume of maxillary sinus were measured in 44 Korean skulls 23 males and 21 females from cadaver. The shapes of the maxillary sinus were classified according to Anagnostopoulou et al. (1991) and the sizes of the medial antral wall area of the maxillary sinus were classified according to Fernandes (2004b). The mean volume of maxillary sinus was 12.83+/-5.41 cm3, which was significantly different between males and females. Bilateral symmetry of the volume of the maxillary sinus was observed in the 70% of the specimens. The width of maxillary sinus was 26.59+/-4.96 mm. The height of maxillary sinus was 26.65+/-6.16 mm. The anteroposterior length was 32.84+/-4.96 mm. The anteroposterior length measured on C-Arm radiography was 36.99+/-4.72 mm. The shape of maxillary sinus was semi-ellipsoid and the majority (50%) of the shape of medial antral wall area of maxillary sinus was the type of small. The results of this study could be useful to clarify the anthropological characteristics of the maxillary sinus in Korean, and to provide an index of ethnic classification for the medial antral wall area.

OBJECTIVE: At present, gold-standard technique of cervical cord decompression is surgical decompression and fusion. But, many complications related cervical fusion have been reported. We adopted an extended anterior cervical foraminotomy (EACF) technique to decompress the anterolateral portion of cervical cord and report clinical results and effectiveness of this procedure. METHODS: Fifty-three patients were operated consecutively using EACF from 2008 to 2013. All of them were operated by a single surgeon via the unilateral approach. Twenty-two patients who exhibited radicular and/or myelopathic symptoms were enrolled in this study. All of them showed cervical cord compression in their preoperative magnetic resonance scan images. RESULTS: In surgical outcomes, 14 patients (64%) were classified as excellent and six (27%), as good. The mean difference of cervical cord anterior-posterior diameter after surgery was 0.92 mm (p<0.01) and transverse area was 9.77 mm2 (p<0.01). The dynamic radiological study showed that the average post-operative translation (retrolisthesis) was 0.36 mm and the disc height loss at the operated level was 0.81 mm. The change in the Cobb angle decreased to 3.46, and showed slight kyphosis. The average vertebral body resection rate was 11.47%. No procedure-related complications occurred. Only one patient who had two-level decompression needed anterior fusion at one level as a secondary surgery due to postoperative instability. CONCLUSIONS: Cervical cord decompression was successfully performed using EACF technique. This procedure will be an alternative surgical option for treating cord compressing lesions. Long-term follow-up and a further study in larger series will be needed.

It is important that the surgeons expect difference in the volume of the maxillary sinus during endoscopic surgery because a variation in volume of the maxillary sinus is related to a variation in anatomical landmarks. Forty four Korean skulls (88 sinuses, 23 M/21F) were used in this study. Anatomical landmarks around the maxillary sinus were measured. The significant variables (r.0.03, P.0.05) out of measured variables were pick out by use of SPSS-13.0 program. The regression equation models were developed by multiple regression analysis. The volume of maxillary sinus showed a high correlation with 19 variables included the width, height, depth of the maxillary sinus, depth on C-arm radiography, length of three borders of maxillary sinus, distance between the lowest point of orbit and the deepest point of maxillary sinus, distance between the deepest point of maxillary sinus and the porion, width of orbit, measured values from akanthion. The regression equation model for prediction of the volume of the maxillary sinus was volume=0.692?(the anteroposterior length of the maxillary sinus)+0.355?(the height of the maxillary sinus)-22.178. This study ascertained variables of a high correlation with volume of the maxillary sinus and would be useful to develop the regression model for prediction of volume of the maxillary sinus.

Giant fusiform aneurysms at the basilar trunk tend to have a poor natural history and surgical management for these aneurysms remains controversial. For these aneurysms, basilar trunk occlusion with endovascular coiling is difficult when the collateral supply from the carotid circulation is relatively poor. Interestingly, we herein present a successfully treated case of a partially thrombosed giant fusiform aneurysm at the basilar trunk with relatively poor collateral supply using endovascular coil occlusion following bypass surgery (superficial temporal artery-radial artery-superior cerebellar artery anastomosis).

OBJECTIVES: To identify the risk factors of cerebrovascular disorders(CVD) in Koreans using a nested case-control study. METHODS: The cohort consisted of beneficiaries who had taken health examinations of the Korea Medical Insurance Corporation (KMIC cohort: 115,600 persons) in 1990 and 1992 consecutively. Four hundred and twenty five (425) cases were selected following the validation of diagnosis among 2,026 reported CVD (I60-I68) inpatients during the year from 1993 to 1997. Controls were matched (1:1) with age and gender of the cases among inpatients without CVD during the same period. The source of data in this study were the files of the 1990 health examinations and the 1992 health questionnaires, as well as an additional telephone survey undertaken from March to November 1999. RESULTS: In a bivariate analysis and multiple logistic regression analysis, risk factors for total CVD were hyperglycemia and hypertension. Unrespectively, the odds ratio of ex-smoker was significantly lower than that of those who had never smoked. The risk factors for ischemic CVD also were hyperglycemia and hypertension. However, only blood pressure was found to be a risk factor for hemorrhagic CVD. Hypercholesterolemia was not a risk factor for total CVD, ischemic CVD, and hemorrhagic CVD. CONCLUSION: We concluded that the most important risk factor for CVD (including subtype) in Koreans was hypertension.
