Dematomyositis is an inflammatory cutaneo-muscular disease of unknown etiology, characterized by symmetrical proximal muscle weakness and typical dermatologic manifestation. Association with systemic maligmancy has been reported in many literatures, but the relationship of dermatomyositis to internal malignancy remains controversial. In Korea, several cases of dermatomyositis or polymyositis associated with malignant neoplasm were reported. Dermatomyositis or polymyositis associated with primary hepatoma has not been reported, Recently authors experienced a patient with dermatomyositis associated with primary hepatoma, and present the case with review of literatures. This may be the first report in Korea.

BACKGROUND: There are many rating scales for assessment of geriatrics. But each of these scales were not sufficient to evaluate comprehensive geriatric assessment, physical and psychologic efforts for care. METHODS: We developed new scales to comprehensive geriatric assessment for care of geriatric patients. The Geriatrics Physical Support Scale(GPSS) evaluates physical effort consists of 10 areas and the Geriatrics Global Support Scale(GGSS) evaluates general condition of patients consist of 6 areas. Eighty probable and possible AD patients received the Clinical Dementia Rating Rating Scale(CDR), Korearn version of Mini-Mental State Examination(K-MMSE), Barthel Activity of Daily Living Index(B-ADL) GPSS, GGSS. We tested internal consistency, correlation among dementia rating scales. RESULTS: The GPSS correlated to CDR -0.63(p<0.01), B-ADL -0.90(p<0.01) and the GGSS correlated to CDR -0.60(p<0.01), B-ADL -0.75(p<0.01). The internal consistency were 0.69(GGSS), 0.92(GPSS). CONCLUSION: The Geriatrics Global Support Scale evaluate general condition of patients and the Geriatrics Physical Support Scale evaluate physical efforts needed for care of geriatric patients. These scales an also brief and easy rating scales to grade degree of caregiver`s burden.

Giant pigmented nevus is a variety of congenital melanocytic nevi, and may be associated with various abnormalities, such as skeletal malformation, lipoma, vascular nevi, melanosis in the meninges, meningocele, and intracranial arteriovenous malformation. We report a case with congenital giant pigmented nevus and porencephaly. This association should be considered as the spectrum of neurocutaneous syndromes related to congenital giant pigmented nevus.

BACKGROUND: Moyamoya disease is a chronic cerebrovascular disorders in which stenosis of the major arteries of the circle of Willis at the base of the skull progresses to occlusion. We observed two kinds of collateral pathways from the extracranial to the intracranial arteries. Also we evaluated clinlcal and neuroimaging features of moyamoya disease to give on aid in diagnosis. METHODS: We analysed 17 patients with moyamoya disease through the medical record and neuroimaging (conventional angiography and/or MR angiography) review. Six out of 17 patients were children(< OR =15 years) and the other 11 patients were adults(15 years). There were 8 males and 9 females. RESULTS: In our result, moyamoya disease was more common in the adult. There was bimodal age distribution, so average age of onset in children was 8-year-old and in adult 37-year-old. Common clinical features are seizure (66%), TIA (17%), and psychotic behavior (17%) in childrens and hemorrhages (73%), infarction (18%), seizures (9%) in adults. According to angiographic staging classification of Suzuki et al. (1967), our cases showed distribution of stage I (13%), stage II (8.8%), stage III (65.3%), stage IV (4.3%), stage V (4.3%), stage VI (4.3%). In collateral vessels of moyamoya disease, there were 7 cases of ethmoidal moyamoya, 3 of vault moyamoya and 1 of mixed form. It is interesting that there were five cases of unilateral moyamoya disease and one case had pseudoaneurysm. CONCLUSION: According to our results, we may say that seizures are common in the children and hemorrhages are in the adult. Unilateral moyamoya were mainly occurred in the adult. Ethmoidal collaterals were common among collaterals and stage III had a more cases than others in our neuroimaging data. These clinical and neuroimaging data may help interpretation and diagnosis of moyamoya disease.

PURPOSE: To compare central macular thickness (CMT) and visual acuity outcomes after intravitreal injection of triamcinolone acetonide or bevacizumab for the treatment of diabetic macular edema (DME). METHODS: Fifty-one patients were randomly choosen to receive an intravitreal injection of either triamcinolone acetonide or bevacizumab. Patients were retrospectively reviewed, and 28 of 51 received an intravitreal injection of triamcinolone acetonide while the remaining 23 received bevacizumab injection. All patients underwent Snellen visual acuity testing, optical coherence tomography imaging and ophthalmoscopic examination at baseline and at four weeks following the injection. RESULTS: In the triamcinolone group, CMT decreased from 656.71+/-194.37 micrometer at baseline to 312.46+/-102.14 micrometer at the four-week follow-up visit, while in the bevacizumab group, CMT decreased from 582.17+/-151.02 micrometer at baseline to 453.09+/-172.39 micrometer at the follow-up (p<0.05). The LogMAR best-corrected visual acuity converted from the Snellen visual acuity significantly improved in the triamcinolone group (from 0.89+/-0.38 to 0.67+/-0.33) compared to the bevacizumab group (from 0.79+/-0.31 to 0.70+/-0.34) [p<0.05]. CONCLUSIONS: Intravitreal injection of triamcinolone may offer advantages over bevacizumab in the short-term management of DME, specifically with respect to improvement in CMT and visual acuity.

PURPOSE: To evaluate the usefulness of dynamic contrast-enhanced T2*-weighted MR imaging for assessing cerebral hemodynamics in acute cerebral infarction. MATERIALS AND METHODS: We performed dynamic T2*-weighted imaging(TR/TE/flip angle : 40/26/10 degrees, 64 x 128 matrix, 5 sec scan time) in conjunction with conventional T1- andT2-weighted imaging and MR angiography in 20 patients with acute cerebral infarction. The regions of ischemia seenon T2-weighted image(high signal intensity), MR angiogram(vascular stenosis or occlusion) and dynamic contrast-enhanced T2*-weighted image(perfusion defect) were topographically compared with each other. Relative cerebral blood volumes(rCBVs) of the ischemic regions and of contralateral normal regions were calculated fromsignal intensity data measured on dynamic contrast-enhanced T2*-weighted images, and were compared. RESULTS: Regions of ischemia were topographically well correlated on T2-weighted image, MR angiogram and dynamic contrast-enhanced T2*-weighted image in all but two patients, of whom one had recanalization of the occluded artery and the other had a small infarction. rCBVs were asymmetrically reduced in the ischemic regions in all butone patient who had recanalization of the occluded artery. CONCLUSION: Dynamic contrast-enhanced T2*-weighted imaging is a useful method in the qualitative and quantitative assessment of cerebral hemodynamics in acutecerebral infarction. The use of this imaging technique along with conventional MR imaging and MR angiography provides better hemodynamic information in acute cerebral infarction.

The purpose of this study was to investigate the pulpal response to direct pulp capping with dentin sialoprotein (DSP)-derived synthetic peptide in teeth of dogs, and to compare its efficacy to capping substances Ca(OH)2 and white mineral trioxide aggregate (WMTA). A total of 72 teeth of 6 healthy male beagle dogs were used. The mechanically exposed pulps were capped with one of the following: (1) DSP-derived synthetic peptide (PEP group); (2) Ca(OH)2 (CH group); (3) a mixture paste of peptide and Ca(OH)2 (PEP+CH group); or (4) white MTA (WMTA group). The access cavity was restored with a reinforced glass ionomer cement. Two dogs were sacrificed at each pre-determined intervals (2 weeks, 1 month, and 3 months). After the specimens were prepared for standard histological processing, sections were stained with hematoxylin and eosin. Under a light microscope, inflammatory response and hard tissue formation were evaluated in a blind manner by 2 observers. In the PEP group, only 3 of 17 specimens showed hard tissue formation, indication that the DSP-derived synthetic peptide did not induce proper healing of the pulp. Compared with the CH group, the PEP group demonstrated an increased inflammatory response and poor hard tissue formation. The CH and WMTA groups showed similar results for direct pulp capping in mechanically exposed teeth of dogs.

Magnetic resonance (MR) imaging techniques that measure cerebral perfusion have become increasingly important. It is due to the limitation of other imaging modalities (single photon emission computed tomography, SPECT ; positron emission tomography, PET etc.) and conventional MR imaging to detect cerebral perfusion, and its ability to identify and quantitate changes in cerebral perfusion may have a substantial effect on both the diagnosis and treatment of cerebrovascular disease. We evaluated the cerebral perfusion and arterial recanalization of large territorial infarction in acute, subacute and chronic stage by MR image and MR angiography and tried to correlate with motor improvement. Twenty six patients with large territorial infarction of middle cerebral artery (MCA, n=23) or posterior cerebral artery (PCA, n=3) were included in this study. In conjunction with conventional brain MR imagings, thirty-four dynamic susceptibility contrast-enhanced MR imagings (DSC-MRI) and MR angiography were performed in acute (< lweek, n=22), subacute (1-3 weeks, n=7), and chronic (3-5weeks, n=5) stages of cerebral infarction. Regional cerebral blood volumes (rCBVs) were calculated on a pixel-by-pixel basis and rCBV images were generated. Perfusion of infarcted areas were compared to contralateral normal regions by rCBV ratio (rCBV of infarcted area/that of contralateral), and arterial recanalization of infarcted area were investigated by MR angiographies. Motor power of the hemiparetic side of the patients was observed during the first 5 weeks after the stroke onset. The rCBVs of ischemic regions increased in subacute period than acute period and decreased again in chronic period (p<0.01, Kruskal Wallis one-way ANOVA), and these patterns were also correlated with visual findings of rCBV images. Recanalization of occluded arteries was found on MR angiagraphy in 3 patients (13.69.1) in acute, 6 patients (85.7%) in subacute and 4 patients (80.0%) in chronic infarction. The increase of "rCBV ratio" was more frequently seen in recanalization than no recanalization cases but we could not statistically analyze the difference due to small size of sample. In MCA infarctions, there is no significant relationship between rCBV with motor improvement during first 5 weeks after the onset. DSC-MRI is noninvasive, more widely available than other functional images (SPECT and PET) and easier to perform in an emergency setting. By providing information about hemodynamics, which is not available with conventional T1 or T2-weighted images, DSC-MRI will be helpful in describing the pathaphysiologic characteristics of stroke.
