Graves disease occur in association with myasthenia gravis is rare. We report a case of Graves disease and myasthenia gravis treated by bilateral subtotal thyroidectomy and total thymectomy simultaneously. A 37 year old woman was admitted with anterior neck mass and ptosis. Various examinations were compatible with combined Graves disease and myasthenia gravis. The bilateral subtotal thyroidectomy and total thymectomy were done simultaneously. The pathologic diagnosis was Graves disease and thymic hyperplasia. The patients postoperative course was uneventful. The thyroid function of patient became euthyroid and the clinical symptoms related with myastenia gravis resolved during follow up period.

In order to assess the reliability of ultrasonographic criteria of clonorchiasis, a prospective study was performed in 14 patients who were diagnosed as clonorchiasis by ultrasonogram only, using the criteria of peripheral duct dilatation without dilatation of extrah epatic duct. Eleven out of 14 patients were turned out to be clonorchiasis, showing 93% accuracy. Authors in tend to stress these ultrasonographic signs are very well correlated with the CT and E RCP findings and are proved to be highly reliable for clonorchiasis, and thus clonorchiasis could be diagnosed by ultrasonogram only.

Since the nose is the most prominent part in the face, the plastic surgeons are interested in the continued effort for rhinoplasty. Nasal tip projection is essential to optimal nasal for the patient's face. But, the nasal tips of Orientals are characterized by bulbous appearance due to thick and tense skin, flaring of nostril. and restriction of nasal tip projection due to underdevelopment of medial crus of alar cartilage and short columella. Most orientals want to correct their nasal tip as well as shape of nose. We present clinical cases of various nasal tip deformities which were corrected with various operative methods through either alar rim incision of open rhinoplasty incision depending upon the severity of tip deformity in order to achieve more natural tips and good nasal tip projection. And the clinical cases were categorized into causes of nasal tip deformity and methods of nasal tip augmentation. We are reporting these reporting these cases with review of literatures.

This article provides an update on tinnitus for audiologists and other clinicians who provide tinnitus-specific services. Tinnitus can be attributable to hearing loss, somatosensory system dysfunction, or auditory cortex dysfunction, with hearing loss being the most common cause and serious underlying pathologies being rare. Hearing loss does not always lead to tinnitus, and patients with tinnitus do not always suffer from hearing loss. The first scenario is explained by a so-called inhibitory gating mechanism, whereas the second assumes that all tinnitus sufferers have some degree of hearing impairment, which might not be detected in standard audiological examinations. The treatments should aim at symptomatic relief and management of associated distress. Current treatment options include pharmacotherapy, education, counseling, cognitive behavioral therapy, and sound therapy.

Each diastereomer of 10-thiophenyl- and 10-benzenesulfonyl-dihydroartemisinin was synthesized from artemisinin in three steps, and screened against chloroquine-resistance and chloroquine-sensitive Plasmodium falciparum. Three of the four tested compounds were found to be effective. Especially, 10 beta-benzenesulfonyl-dihydroartemisinin showed stronger antimalarial activity than artemisinin.

PURPOSE: To analyse the radiological findings of bizarre parosteal osteochondromatous proliferation (BPOP), a rare benign tumorous lesion with a high frequency of recurrence which frequently occurs around the short tubular bones of the hands and feet. MATERIALS AND METHODS: Between 1984 and 1998, 19 cases of BPOP were pathologically Proven, and in is of these, six men and nine women aged between 17 and 69(mean, 41) years, plain radiographs were available for analysis. We examined the location and size of lesions, and their relationship to adjacent bone. RESULTS: In all cases, trabecular bone formations were present. There were not separable from adjacent bones, which in all cases appeared normal. In nine of 15 cases margins were sharp, and in the remaining six they were irregular. Lesions were located around a phalanx of the hand (n=5), a metatarsal bone (n=3), a long bone (n=3), a phalanx of the foot (n=2), a metacarpal bone (n=1), and a metatarsophalangeal joint (n=1). Their average size was 2.5 x1.9cm, and in three of is cases the tumor recurred. CONCLUSIONS: BPOP showed a well-marginated mass of heterotopic mineral arising around short tubular bones. These findings were useful for diagnosis and differential diagnosis.

Simple or unicameral bone cysts are metaphyseal lesions of long bones. They usually move away from the physiswith growth to become diaphyseal in location. Involvement of the physis and epiphysis by these cystic lesions isvery rare. This paper reports a case of simple bone cyst of the proximal humerus in a 11- year -old girl which wasshown by MR imaging to extend through the physis into the epiphysis.

Although many papers concerning the ultrasonographic findings of liver abscess have been appeared, there is afew literatures for the analysis of its echognic patterns. Twenty-nine cases of surgically proven liver abscesswere studied by ultrasonography in our hospital during recent 3 years. The results were as follows: 1.Ultrasonography permitted correct diagnosis in 26 of 29 patients with sensitivity 90%. 2. All the 7 cases ofamebic abscess were single lesions and 6 cases of them were distributed in the right lobe of liver, while pyogenicabscesses showed single or multiple lesions. It was very difficult to distinguish pyogenic abscess from amebicabscess in cases of single lesion. 3. It was impossible to differentiate pyogenic abscess from amebic abscess bythe echopattern of abscess wall and internal echogenicity. 4. The wall of obscess was ill-defined in the majority,and internal echogenecity of abscess was variable although weak internal echogenecity was more comon. 5. Theechopattern of abscess was gradually converted to echolucent or hypoechoic area with weak internal echoes infollowing up study. 6. Clinical findings and ultrasonic findings should be carefully analysed to secure correctdiagnosis of there is any possibility of co-existing necrotizing metastatic lesion.

With the development of gray scale ultrasonography, detection and evaluation of hepatic parenchymal diseaseincluding space occupying lesions are easitly performed and frequently used in the world. Thirty-five cases ofhistopathologically proven and ultrasonographically suggested hepatocellular carcinoma are retrospectivelystudied. The results were as follows; 1. Ultrasonographic findings of hepatocellular carcinoma show hyperechoicpattern in 22 cases (63%), hypoechoic pattern in 2 cases (6%), and mixed pattern in 11 cases (31%). 2. The marginof tumor is ill-defined in 19 cases (54%) and well defined in 16 cases (46%). 3. The size of tumor by sonographicmeasurement was larger than 5cm in diameter in 33 cases (94%). 4. The number of tumor is solitary in 19 cases andmultiple in 16 cases. The sites of involved lobe were right lobe in 22 cases (63%), left lobe in 2 cases (6%), andboth lobes in 11 cases (31%). 5. Associated sonographic findings were hepatomegaly with focal contour change in 25cases (71%), splenomegaly in 16 cases (46%), cirrhosis of liver in 15 cases (43%), ascites in 11 cases (31%) andtumoral thrombosis in portal vein in 8 cases (23%). 6. The sex ratio is 6:1 male predominence and the age rangesfrom 32 to 76 years with highest incidence in 5th and 6th decades.

PURPOSE: To evaluate a role as over 35 years, maternal serum markers, and a false positive screen for Down syndrome were the predictor of adverse pregnancy outcome. Materials and METHODS: From Mar.1994, through Feb.1996, 5284 women were screened triple test to detect Down syndrome in the second trimester and were delivered Samsung Cheil hospital. The values of each maternal serum markers were measured with radioimmunoassay. And then, the screen positive of Down syndrome was calculated using alpha-software Version 4.0. The adverse outcome of the fetus and the mother included low birth weight(LBW) ( <2500gm), prematurity( <37 gestational weeks), placenta previa, preterm premature rupture of membranes(PPROM), pregnancy induced hypertension(PIH),abruptio placenta, and intrauterine fetal death(IUFD). The predictor markers included over 35years, elevated alpha-fetoprotein (AFP), elevated human chorionic gonadotropin(hCG), lowered unconjugated estriol (uE3), and a false positive screen for Down syndrome. RESULTS: Mean age and mean gestational weeks in the study were 30+/-4.8 years and 17.1 weeks respectively. The adverse pregnancy outcomes were 357 LBW(6.8%), 253 prematurity(4.8%), 108 placenta previa(2.0%), 68 PPROM(1.3%), 66 PIH(1.3%), 24 abruptio placenta(0.5%), and 20 IUFD(0.4%). In univariate analysis, over 35 years was significantly associated with abruptio placenta, prematurity, and placenta previa, elevated MS-AFP( >2.0 MoM) associated with IUFD, LBW, PIH, prematurity, and PPROM , elevated MS-hCG (>3.0 MoM) associated with IUFD, LBW, PIH, prematurity, and placenta previa, lowered uE3 (<0.75) associated with IUFD, abruptio placenta, LBW, and prematurity.(P <0.05). In multivariate logistic regression analysis, IUFD was significantly associated with only elevated MS-AFP, LBW associated with elevated MS-AFP, elevated MS-hCG, and lowered uE3, PIH associated with only elevated MS-AFP, PPROM only elevated MS-AFP, prematurity only elevated MS-AFP, and placenta previa over 35 years, elevated MS-hCG.(P <0.05). However, abruptio placenta was not significantly associated with predictor markers.(P >0.05) CONCLUSIONS: Some predictors such as over 35 year, elevated hCG, lowered uE3, a false positive screen for Down syndrome were significantly associated with adverse pregnancy outcome. Also in multivariate analysis, we identified especially elevated AFP to be the most reliable predictor for adverse pregnancy outcome.
