저자들은 하지 자색반과 고환 통증으로 내원한 알코올성 간경화증 환자에서 LCV의 원인 감별하는 과정에서 HCC와 하대정맥 막성폐쇄를 진단하고 이에 대한 치료 후 LCV의 호전된 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Vasculitis is a heterogeneous group of diseases that destroy blood vessel walls by inflammation. Approximately half of vasculitis cases are idiopathic, but sometimes associated with genetic factors, medicines, chronic infection, autoimmune diseases, and malignancies. Although the mechanism remains unclear, vasculitis secondary to malignancy, also known as paraneoplastic vasculitis, has been reported. It is generally associated with hematologic malignancies rather than solid malignancies and commonly presents as leukocytoclastic vasculitis or polyarteritis nodosa. We experienced a case of leukocytoclastic vasculitis in a patient with hepatocellular carcinoma and membranous obstruction of the inferior vena cava. Here, we report this case with a brief review of literature. (J Rheum Dis 2015;22:322-326)

<P><I>BACKGROUND:</I> Although pazopanib treatment has become the standard chemotherapy in salvage setting for metastatic sarcoma patients, most patients progress after pazopanib treatment in 4 to 6 months. After failure to pazopanib, patients have limited options for treatment. Therefore, subsequent therapy in patients who failed to pazopanib is urgently needed and the use of patient derived cells or patient derived tumors for accompanying testing with various pharmacological inhibitors could offer additional treatment options for these patients. <I>METHODS:</I> Patient derived tumor cells were collected from ascites at the time of progression to pazopanib and a 13-drug panel was tested for drug sensitivity. We confirmed the results using <I>in vitro</I> cell viability assay and immunoblot assay. We also performed the genomic profiling of PDX model. <I>RESULTS:</I> The growth of patient derived tumor cells was significantly reduced by exposure to 1.0 μM AZD2014 compared with control (control versus AZD2014, mean growth = 100.0% vs 16.04%, difference = 83.96%, 95% CI = 70.01% to 97.92%, <I>P</I> = .0435). Similarly, 1.0 μM BEZ235 profoundly inhibited tumor cell growth <I>in vitro</I> when compared to control (control versus BEZ235, mean growth = 100.0% vs 7.308%, difference = 92.69%, 95% CI = 78.87% to 106.5%, <I>P</I> < .0001). Despite the presence of CDK4 amplification in the patient-derived tumor cells, LEE011 did not considerably inhibit cell proliferation when compared with control (control vs LEE011, mean growth = 100.0% vs 80.23%, difference = 19.77%, 95% CI = 1.828% to 37.72%, <I>P</I> = .0377). The immunoblot analysis showed that BEZ235 treatment decreased pAKT, pmTOR and pERK whereas AZD2014 decreased only pmTOR. <I>CONCLUSION:</I> Taken together, upregulation of mTOR/AKT pathway in sarcoma patient derived cells was considerably inhibited by the treatment of AZD2014 and BEZ235 with downregulation of AKT pathway (greater extent for BEZ235). These molecules may be considered as treatment option in STS patient who have failed to pazopanib in the context of clinical trials.</P>

This study analyzes the effect of capital investment on firm valuation. The portfolios classified by size and B/M have different extent of capital expenditure. It is found that the capital expenditure on total assets can explain returns to portfolios. Specifically, firms showing lower B/M ratios are found to invest more and are with greater market values. Firms showing greater B/M ratios show the other side but with increasing capital expenditures afterwards. Market valuation, however, does not reveal any consistent patterns. Our results also show that firms with formerly higher capital expenditures are shown to be linked to significantly lower stock returns

The purpose of this study is to investigate the variation of pore size distribution of the coal-based extruded activated carbon. The extruded activated carbon was prepared by extruding the mixture of coal powder and coal tar. Pore size distribution of the extruded activated carbon was compared with that of the extruded coal and the extruded char. Also it was compared with that of the crushed activated carbon, raw coal and char. The extruded coal had coarser surface than that of raw coal. Macropores of the extruded coal were funned near 10,000Å in diameter during carbonization process and steam penetrated easily between particles and were growing between 3,000Å and 20,000Å in diameter during activation process.

The prevalence of respiratory symptoms and pulmonary function were studied in a group of 55 whole-sale market merchants Working in underground. As a control group, 55 whitecollar workers was also included in this study. Following results were obtained. A higher complaint for respiratory symptoms(cough, sputum, chest tightness, shortness of breath) was found among merchants than control workers. The measurement value for FVC, FEV1.0, FEV 1.0% in the merchants were reveal to lower figure in comparison with control groups. The measurement Value for MVV, PEF in the merchants were lower than control groups, but was not significant statistically. The pattern of pulmonary ventilation disturbance in the whole-sale market merchant were the same as followings : restrictive disturbance(6 person), abstrictive disturbance(1 person), and combined disturbance(1 person).

Although many dermatologists need adequate information about Agent Orange-related skin lesions, there have been few researches about them. We observed various skin manisfestations from 266 Korean Vietnam veterans who visited Department of Dermatology, Chungnam National University Hospital, inculding seborrheic dermatitis(46%), xerotic eczema(45%), chloracne(30%), generalized pruritus (10%), dermographism (5%), chronic urticaria (4%), photosensitive dermatitis (3%), etc. Among them chloracne is well known as a disease which results from exposure to Agent Orange which was used for a defoliating agent during Vietnam war. It is a refractory acneiform eruption due to halogenated polyaromatic compounds(eg. dioxin, dibenzofurane, polychlorinated biphenyls, etc.). 2,3,7,8-tetrachlorodibenzo-p-dioxin, a kind of dioxin isomer, contained in the Agent Orange which was used for a defoliating agent during Vietnam war. It is characterized by recalcitrant comedones and cysts predominantly in the malar and postauricular area. We concluded that the various skin lesions in Vietnam veterans resulted from probably the chemicals in defoliant and further researches would be required to find out subjective guidelines for the evaluation of the skin lesions.
