Familial Mediterranean Fever (FMF) is a hereditary autoinflammatory disease, which is characterized by recurrent and paroxysmal fever, peritonitis, arthritis, myalgia, and skin rashes. Although various skin lesions such as “erysipelas‐like erythema”, urticaria, nonspecific purpura, and subcutaneous nodules have been described, cutaneous vasculitis is rare. We report a Japanese case of sporadic FMF accompanied by cutaneous arteritis at the time of febrile attacks of FMF. Gene analysis revealed M694I mutation in a single allele of the MEFV gene, and oral colchicine successfully controlled both periodic fever and subcutaneous nodules of arteritis. Cutaneous necrotizing vasculitis repeatedly emerging with febrile attacks should be included among the skin manifestations of FMF. 相似文献

The incidence and characteristics of cement-asbestos pneumoconiosis were compared with those of asbestosis and cement pneumoconiosis in three homogeneous samples of cases. The clinical, functional, and radiological features of cement-asbestos pneumoconiosis are similar to those of classical asbestosis, but the observed changes are less common and occur after a longer exposure. 相似文献

Whether parapsoriasis represents an early stage of T-cell cutaneous lymphoma is still
the subject of controversy. We evaluated the efficacy of phototherapy in the
treatment of parapsoriasis and its relation with TCCL. Patients diagnosed with
parapsoriasis and treated with phototherapy PUVA or UVB-NB were selected. Between 1
to 8 years following treatment the evolution of their disease was evaluated. In 62
patients the cure rate was 79.3% and 17.2% showed improvement of the lesions. Only
two patients developed full blown T-cell cutaneous lymphoma. Phototherapy is an
excellent treatment for parapsoriasis, with high cure rates, regardless of the type
of phototherapy employed. Of the 62 patients under study, parapsoriasis showed no
general tendency to progress to T-cell cutaneous lymphoma. 相似文献

A better understanding of the biological factors underlying antidepressant treatment in patients with major depressive disorder (MDD) is needed. We perform gene expression analyses and explore sources of variability in peripheral blood related to antidepressant treatment and treatment response in patients suffering from recurrent MDD at baseline and after 8 weeks of treatment. The study includes 281 patients, which were randomized to 8 weeks of treatment with vortioxetine (N = 184) or placebo (N = 97). To our knowledge, this is the largest dataset including both gene expression in blood and placebo-controlled treatment response measured by a clinical scale in a randomized clinical trial. We identified three novel genes whose RNA expression levels at baseline and week 8 are significantly (FDR < 0.05) associated with treatment response after 8 weeks of treatment. Among these genes were SOCS3 (FDR = 0.0039) and PROK2 (FDR = 0.0028), which have previously both been linked to depression. Downregulation of these genes was associated with poorer treatment response. We did not identify any genes that were differentially expressed between placebo and vortioxetine groups at week 8 or between baseline and week 8 of treatment. Nor did we replicate any genes identified in previous peripheral blood gene expression studies examining treatment response. Analysis of genome-wide expression variability showed that type of treatment and treatment response explains very little of the variance, a median of <0.0001% and 0.05% in gene expression across all genes, respectively. Given the relatively large size of the study, the limited findings suggest that peripheral blood gene expression might not be the best approach to explore the biological factors underlying antidepressant treatment.Subject terms: Predictive markers, Depression 相似文献
