Several observation suggest that the antimelanocyte autoantibodies could play a role in melanocyte destruction. Some experiments indicate that melanocyte antibodies from patients with vitiligo can kill melanocyte in vitro. In these experiments, we demonstrated that vitiligo patient's sera containing antimelanocyte antibodies can lyse cultured human melanocytes by complement activation. Melanocyte cytotoxicity was measured using the ethidium bromide/ acridine orange viability assay. Significant melanocyte cytotoxicity was seen in sera from patients with both active and inactive vitiligo(p<0.01). Melanocyte cytotoxicity measured with complement-mediated cytotoxicity decreased after systemic steroid treatment(p<0.05) ; however melanocyte cytotoxicity showed no significant change with systemic PUVA therapy.

PURPOSE: MRI is known to be an effective imaging modality of the aorta and its role is steadily increasing in the evaluation of acquired aortic diseases including aortic dissections and aortic aneurysms. However, differentiation of the aortic dissections with thrombosed false lumen from the aortic aneurysm with mural thrombus in MRI has not been easy. Therefore, the authors tried to find the characteristic MR featrses which would to differentiate the two diseases. MATERIALS AND METHODS: MR images of 6 patients with thrombosed aortic dissection and 7 patients with thrombosed aortic aneurysms were reviewed retrospectively and compared in regand to shape and extent of thrombus, dimension of aorta, and luminal flow signal. RESULTS: Thrombosed aortic dissections showed sharply demarcated crescent shaped aortic wall thickening of even thickness involving long segment of the aorta, whereas thrombosed aortic aneurysms showed irregular aortic wall thickening of uneven thickness localized in the short dilated segment of the aorta. Characteristically aortic aneurysm with mural thrombus showed eccentric intraluminal slow flow signal. In contrast to the signal void of the true lumen in aortic dissections, the residual lumen of the aortic aneurysm with mural thrombus revealed intraluminal signal due to slow flow. CONCLUSION: Familiarity to these MRI findings of thrombosed aortic dissections and aortic aneurysms may lead to the accurate differential diagnosis in majority of cases.

8.Clinical Factors Associated with Quality of Life in Patients with Thyroid Cancer.

The incidence of thyroid cancer is rapidly increasing worldwide. Recently, attention to quality of life (QOL) issues has been increasingly addressed in the management of cancer. The goal of this review is provide a systematic overview for clinical factors associated with QOL in patients with thyroid cancer. Age is often cited as a QOL predictor with older patients more vulnerable than younger patients. High levels of fatigue and psychological distress such as anxiety and depression might be associated with decreased QOL. Although surgery for thyroid cancer leads to worse QOL shortly, there is a trend towards recovery with time. Levothyroxine treatment in thyroid cancer can result in similar or slightly impaired QOL. Thyroid hormone withdrawal causes significant reductions of QOL of thyroid cancer patients. The use of recombinant human thyrotropin (rhTSH) instead of thyroid hormone withdrawal can prevent QOL deterioration by thyroid hormone withdrawal. Generally, thyroid cancer survivors have a similar or slightly worse QOL compared with the normative population. In conclusion, thyroid cancer has a considerable impact on QOL of patients, and therefore multidisciplinary approach with special concern for QOL is recommended.

We have encountered a rare case of erythema nodosum-like leukemia cutis associated with acute myelocytic leukemia(AML) in a 57-year-old male. He was in good health until about 2 weeks prior to admission, when the systemic symptoms of high fever, anorexia, general weakness and malaise, and subcutaneous nodules developed. The nodules were multiple, red and noted bilaterally on the pretibial areas. Histological findings of his skin lesions showed diffuse cellular infiltrates intermingled with leukemic cells predominantly involving the adipose tissues. The cells displayed negative stainirig to antibodies CD3 and CD20, but positive staining to LCA. The diagnosis of AML(M4) was made by blood and bone marrow studies. He had a rapid downhill course and was discharged after 2 weeks of admission, with no anti-cancer chemotherapy.
