Six cases of congenital coronary arteriovenous fistulae were diagnosed radiographically and confirmed afteroperation at Seoul National University Hospital in recent three and a quarter years since 1979. The clinical andradiological findings with the emphasis on the cinecardiographic findings were analysed. The summaries of theanalysis are as follows; 1. Among 6 cases, 2 cases were male and 4 cases were female. Age dsitribution was from 3months to 19 years. 2. In chest x-ray findings, 5 cases had cardiomegaly. Among these 5 cases, increase ofpulmonary vascularity was in 3 cases. Chest X-ray finding of the rest 1 case was within normal limit. 3. Thecoronary arteriovenous fistula orginated from the right coronary artery in 5 cases and from the single left coronary artery in 1 case. In 5 cases, a coronary arteriovenous fistula drained into the right ventricle and in 1case, a fistula from a SA node branch of the right coronary artery into the right atrium. 4. In 5 cases, a mainright coronary artery was dilated. Among these 5 cases, aneurysmal dilatation of main right coronary artery was in2 cases, saccular aneurysmal dilatation of distal portion of right coronary artery was in 2 cases and in 1 case,diffuse dilatation without aneurysm formation of a main right coronary artery. In 1 case, SA node branch of theright coronary artery was dilated with aneurysm formation. 5. For accurate diagnosis of congenital coronaryarteriovenous fistula, biplane cinecardiography is an essential procedure.

In our review of 36 hematogenous osteomyelitis nine cases were subacute form. Distal tibia was the most commonly involved location(four of nine patients). According to the modified Robert's classification cross-physeal lesions were the most common type(four of nine patients). In most of the cases the clinical findings and laboratory data were not much helpful for current diagnosis. Four patients had radiographic findings similar to those of tumors such as Ewing' s sarcoma, osteoid osteoma or bone cyst. Magnetic resonance imaging was useful in the identification of early lesions. In three patients Staphylococcus aureus was isolated by bacterial culture of biopsy specimen. In the remaining six patients diagnosis was made by histological evaluation. All patients except one were treated by curettage and antibiotics. In the other patient the disease showed a tendency of spontaneous healing without operative intervention and antibiotics. Cross-physeal lesion seemed to be a typical finding of the subacute osteomyelitis.

5.Sunitinib-induced hypothyroidism.
Korean Journal of Medicine 2010;79(5):506-508
Sunitinib is an oral multi-targeted tyrosine kinase inhibitor that is effective for advanced renal cell carcinoma and imatinib-resistant gastrointestinal stromal tumor. Currently, sunitinib is being investigated in multiple other tumor types including non-small cell lung cancer, breast cancer, colon cancer, and endocrine tumors. Recent studies have shown that sunitinib induces thyroid dysfunction, mainly hypothyroidism during treatment. The incidence of sunitinib-induced hypothyroidism has been reported to be 36~85%. Although several hypotheses have been suggested, the mechanisms by which sunitinib induces hypothyroidism are not clear. As considered the fairly high incidence of sunitinib-induced hypothyroidism, thyroid function should be regularly monitored in all patients treated with sunitinib.

BACKGROUND AND OBJECTIVES: There are caloric test, SCEP, DP in Step velocity and VOR asymmetry in SHA test as parameters for evaluation in unilateral peripheral vestibulopathy in parameter of vestibular function test. The aim of this study is to assess the correlation between these parameters and intensity of spontaneous nystagmus in vestibular neuritis. MATERIALS AND METHOD: We evaluated 75 patients who were diagnosed as vestibular neuritis with 3 degree spontaneous nystagmus at vestibular function test lab from January 2000 to July 2005 in Dankook university hospital. The correlations between direction and intensity of spontaneous nystagmus and monothermal caloric test, SCEP and DP in step velocity, VOR asymmetry (0.01, 0.04, 0.16 Hz) in SHA test were analysed. And correlations according to sex, age were also analysed. RESULTS: The correlation coefficient between intensity of spontaneous nystagmus and monothermal caloric test was 0.60. The correlation coefficient between intensity of spontaneous nystagmus and SCEP was 0.35. The correlation coefficient between intensity of spontaneous nystagmus and Tc DP was 0.36 and it showed no significant correlation. The correlation coefficient between intensity of spontaneous nystagmus and VOR asymmetry (0.01, 0.04, 0.16) was 0.57, 0.46, 0.51, respectively and there was higher correlation in man, age under 60. CONCLUSION: Intensity of spontaneous nystagmus showed close relations to monothermal caloric test, VOR asymmetry of SHA, Tc DP, SCEP DP in sequence. In addition, young male patients tends to be closely related to intensity of spontaneous nystagmus.

We report two cases of hyalinizing trabecular carcinoma (HTC) of the thyroid gland. These two patients were euthyroid women aged 36 and 65 years of age. The tumors were encapsulated and measured 0.8 and 4.0 cm in diameter, respectively. Histologically, the tumors were composed of a compact proliferation of cells in a lobular and trabecular pattern with an intervening hyalinized, fibrotic vascular stroma. Occasionally the cells were arrayed in microfollicles. Multiple and serial sections showed cords of tumor cells invading into the capsule in both cases and vascular invasion in one case. These findings suggested that HTCs are a malignant counterpart of hyalinizing trabecular adenoma, similar to conventional follicular tumor. Positive immunostaining of tumor cells for thyroglobulin and negative staining for high molecular weight cytokeratin, cytokeratin 19, neuron specific enolase, chromogranin, and synaptophysin allowed distinction from medullary carcinoma. Even though HTCs are an heterogeneous group of tumors, the present two cases are probably variants of follicular carcinoma rather than papillary carcinoma.

In vivo ethane production in rats was used as an index of oxygen toxicity. The rats were allocated to four exposure conditions; hyperbaric oxygenation (HBO=5 ATA, 100% O2), normobaric oxygenation (NBO=1 ATA, 100% O2), hyperbaric aeration (HBA=5 ATA, 21% O2) and normobaric aeration (NBA=1 ATA, 21% O2). After 120 minutes of exposure, the rats exposed to high concentration and/or high pressure oxygen exhaled significantly larger amounts of ethane than those exposed to NBA, and the differences in ethane production between any two groups were statistically significant (p<0.01). This finding supports the hypothesis that hypothesis that hyperoxia increase oxygen free-radicals and the radicals produce ethane as a result of lipid peroxidation. It is notable that the ethane exhalation level of the HBA group was significantly higher than that of the NBO group. This difference could not be accounted for by the alveolar oxygen partial pressure difference between the two groups.

The metal ceramic crown is currently the most popular complete veneer restoration in dentistry, but in many cases, the metal cervical collar at the facial margin is unesthetic and unacceptable. Facial porcelain margin has been used in place of it. But this dose not solve the problems, such as dark gingival discoloration and cervical opaque reflection of porcelain veneer. Recently, metal copings which were designed to terminate its labio-cervical end on the axial walls coronal to the shoulder have been clinically used to solve the esthetic problem of metal ceramic crown. But in this design, porcelain veneer of labio-cervical area which is not supported by metal may not be able to resist the stress during cementation and mastication. The purpose of this study was to evaluate fracture strength and fractured appearance of crowns according to different coping designs. A resin maxillary left central incisor analogue was prepared for a metal ceramic crown, and metal dies were made with duplication mold. Metal copings were made and assigned to one of four groups based on facial framework designs: group 1, coping with 0.5mm metal collar; group 2, metal extended to the shoulder; group 3, metal extended to 1 mm coronal to the shoulder; group 4, metal extended to 2mm coronal to the shoulder. Copings and crowns were adjusted to be same size and thickness, and cemented to metal dies with zinc phosphate cement by finger pressure. Fracture strength was measured with Instron Universal Testing Machine. Metaldies were anchored in Three-way-vice at 3mm below finish line and at 130degree inclined to the lone axis of the crown. Load was directed lingually at 2mm below midincisal edge. Load value at initial crack and at catastrophic fracture was recorded. The results obtained were as follows: 1. Fracture strength values at initial crack were higher in groups 1, 2 than in groups 3, 4 but this difference was not statistically significant(P<0.05). 2. Conventional metal collared crown had greater catastrophic fracture strength than any other collarless crowns. 3. The greater the labial metal coping reduction, the lower the catastrophic fracture strength of crowns but when more than 1mm of labial metal reduction was done, the difference in strengths was not statistically significant(p<0.05). 4. The strongest collarless coping design was group 2.
