Results: No haemosiderin deposition was found in normal skin of C2, C3 and C4A legs, in less severe regions of pigmentation and in some parts of more severely affected limbs. Haemosiderin was always present

in lipodermatosclerotic skin and ulcers. Occasionally, haemosiderin was found in the apparently normal selleck chemicals perilesional skin of C4b and C6 legs. The regenerating dermis at the base of healing ulcers showed none or light haemosiderin deposition.

Conclusion: Iron overload is not present in the less severe stages of skin damage due to CVD but lipodermatosclerosis and leg ulcers are always accompanied by haemosiderin deposition. In fact, no severe skin changes occur in CVD legs until iron overload occurs. Our results are in agreement with previous reports suggesting that a genetic inability to counteract skin

iron overload is present in these patients. A more detailed analysis of disordered iron metabolism should be undertaken in CVD patients. (C) 2010 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.”

“OBJECTIVE: To analyze major histocompatibility complex expression in the muscle fibers of juvenile and adult dermatomyositis.

METHOD: In total, 28 untreated adult dermatomyositis patients, 28 juvenile dermatomyositis patients (Bohan and Peter’s criteria) and a control group consisting of four dystrophic and five Pompe’s disease patients were analyzed. Routine histological and immunohistochemical (major histocompatibility complex I SCH772984 and

II, StreptoABComplex/HRP, Dakopatts) analyses were performed on serial frozen muscle sections. Inflammatory cells, fiber damage, perifascicular atrophy and increased connective tissue were analyzed relative to the expression of major histocompatibility complexes I and II, which were assessed as negatively or positively stained fibers in 10 fields (200X).

RESULTS: The mean ages at disease onset were 42.0 +/- 15.9 and 7.3 +/- 3.4 years in adult and juvenile dermatomyositis, respectively, and the symptom durations before muscle biopsy were similar in both groups. No significant differences were observed regarding gender, ethnicity and frequency of organ involvement, except for higher creatine kinase and lactate dehydrogenase levels in adult dermatomyositis (p<0.050). Moreover, a significantly higher frequency of major histocompatibility complex I (96.4% vs. 50.0%, p<0.001) compared with major histocompatibility complex II expression (14.3% vs. 53.6%, p = 0.004) was observed in juvenile dermatomyositis. Fiber damage (p = 0.006) and increased connective tissue (p<0.
