Abstract
The insufficiency of Friend leukaemia virus integration 1 (Fli1), a member of the Ets family transcription factors, is implicated in the pathogenesis of vasculopathy associated with systemic sclerosis (SSc). Fli1 deficiency accelerates early steps of angiogenesis, including detachment of pre-existing pericytes and extracellular matrix degradation by endothelial proteinases, but the impact of Fli1 deficiency on the other steps of angiogenesis has not been investigated. Therefore, we evaluated the effect of Fli1 deficiency on migration, proliferation, cell survival and tube formation of human dermal microvascular endothelial cells (HDMECs). HDMECs transfected with FLI1 siRNA exhibited a greater migratory property in scratch assay and transwell migration assay and a higher proliferation rate in BrdU assay than HDMECs transfected with non-silencing scrambled RNA. In flow cytometry-based apoptosis assay, FLI1 siRNA-transduced HDMECs revealed the decreased number of annexin and propidium iodide-double-positive apoptotic cells compared with control cells, reflecting the promotion of cell survival. On the other hand, tubulogenic activity on Matrigel was remarkably suppressed in Fli1-deficient HDMECs relative to control cells. These results indicate that Fli1 deficiency promotes migration, proliferation and cell survival, while abating tube formation of endothelial cells, suggesting that Fli1 deficiency is potentially attributable to the development of both proliferative obliterative vasculopathy (occlusion of arterioles and small arteries) and destructive vasculopathy (loss of small vessels) characteristic of SSc vasculopathy.

Abstract
We report a case of a 64-year-old man with POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin changes) syndrome that had been previously misdiagnosed as systemic sclerosis. He had typical symptoms of POEMS syndrome, however, the existence of skin sclerosis, contracture of fingers and pigmentation were similar to that of systemic sclerosis. Ten patients, including the patient discussed in this case, visited our department between 1990 and 2011. Among them, five patients had skin sclerosis. Therefore, we compared skin lesions and clinical/laboratory features of POEMS syndrome and systemic sclerosis in an attempt to distinguish these disorders. Regarding the cutaneous and laboratory findings, the existence of hemangioma or hypertrichosis is indicative of POEMS syndrome. By contrast, the existence of systemic sclerosis-specific autoantibodies, nail fold bleeding, digital ulcer/digital pitting scar or telangiectasia is highly suggestive of systemic sclerosis. To our knowledge, this is the first report to discuss in detail the differentiation between POEMS syndrome and systemic sclerosis.

Abstract
We describe the case of a patient with anticentriole antibody-positive scleroderma spectrum disorder (SSD) who developed pulmonary hypertension. A 54-year-old woman had noticed Raynaud's phenomenon and digital ulcers during the winter for the past 10 years. Although sclerodactyly was not present, digital ulcers, swelling of her hands, and phalangeal contracture were observed. An indirect immunofluorescence test revealed anticentriole antibody. Other SSc-specific antoantibodies were negative. An echocardiogram demonstrated that the estimated right ventricular systolic pressure was increased to 51 mmHg. She was diagnosed as SSD with pulmonary hypertension. This is the first case of SSD with anticentriole antibody to develop pulmonary hypertension.

Abstract
OBJECTIVE To describe and quantify the morphological characteristics of nailfold capillaries that distinguish different forms of connective tissue disease from healthy controls. METHODS A CCD video microscope with fibreoptic illumination and PC based image processing was used to visualise nailfold capillaries and to quantify findings in 23 patients with systemic sclerosis (SSc), 22 patients with systemic lupus erythematosus (SLE), 21 patients with undifferentiated connective tissue disease (UCTD), and 38 healthy controls. RESULTS Capillary density was reduced in SSc (5.2 (SD 1.3) capillaries/mm) compared with other patient groups and controls. The average number of enlarged capillaries/finger was high in all disease groups (5.5-6.6) compared with controls (2). However, giant capillaries were most frequent in SSc (43%) and were not present in controls. Mild and moderate avascular areas were present in all groups (35%-68%), but severe avascularity was most frequent in SSc (44%) compared with other patients (18%-19%) and controls (0%). The greatest frequency of extensive haemorrhage was in SSc (35%). CONCLUSIONS There is a range of abnormal capillary findings in patients with connective tissue disease and healthy controls. However, certain abnormalities such as a reduced number of capillaries, severe avascularity, giant capillaries, and haemorrhage are most commonly associated with SSc. Videomicroscopy with image processing offers many technical advantages that can be exploited in further studies of nailfold capillaries.

Abstract
BACKGROUND Recently we demonstrated the presence of antihistone antibodies (AHA) in localized scleroderma. OBJECTIVE Our purpose was to determine clinical characteristics associated with AHA in patients with localized scleroderma. METHODS We examined 57 serum samples by an enzyme-linked immunosorbent assay in the following three subgroups: 15 patients with generalized morphea, 27 with linear scleroderma, and 15 with morphea. We classified the patients as having generalized morphea when they had four or more lesions on at least two areas of the body, irrespective of whether the lesions were of morphea or linear type. RESULTS AHA were detected in 42% of patients with localized scleroderma (24 of 57), and in 87% of patients with generalized morphea (13 of 15). The presence of AHA strongly correlated with the number of morphea lesions, the total number of lesions, and the number of involved areas of the body. However, AHA did not correlate with the presence or number of linear lesions. The presence of AHA showed a 87% sensitivity (13 of 15 patients) and a 74% specificity (31 of 42 patients) for generalized morphea. CONCLUSION Our data suggest that AHA are a serologic marker for generalized morphea and that the validity of our new classification for generalized morphea is supported by the high frequency of AHA detection.
