Interstitial lung disease in systemic sclerosis
No full textInterstitial lung disease is an early and serious complication of systemic sclerosis (SSc). Because it may be asymptomatic for a long period, and only the early flogistic phase is at present susceptible to treatment, early diagnosis and identification of risk are critical to the outcome. However, identifying SSc patients at risk for developing interstitial lung disease is at present difficult; therefore, a strict monitoring of the disease, especially in the first years, is mandatory. Treatment strategy is aimed at suppressing inflammation. Unfortunately, optimal therapy has not yet been established. Combination of corticosteroids and cyclophosphamide is considered the best therapeutic approach available so far, but doses and duration of treatment need to be determined. Future research should focus on new anti-inflammatory or immunosuppressive agents

Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Systemic sclerosis and cancer
No full textTo review recent advances and current controversies on the association between systemic sclerosis (SSc) and cancer, PUBMED was searched from 1966 to the present using the terms: systemic sclerosis, cancer, morphoea, sclerotic diseases. Malignancies, mainly in lung and breast, coexist with idiopathic SSc or with SSc-like disorders, but not with localized forms of scleroderma (morphoea), with the exception of squamous cell carcinoma in patients with pansclerotic morphoea and skin ulcers. The mechanisms connecting SSc and malignancies are unknown. The occurrence of different cancer types with SSc or SSc-like disorders suggest different underlying mechanisms, including altered immune response, common genetic and environmental links, disease-dependent factors, tumor-derived biologic substances and therapies. The process of sclerosis itself may favour cancer in certain sites, and a reaction between T cells and neoantigens formed during irradiation has been suggested to explain the frequent development of morphoea after breast irradiation. Radiotherapy, especially when used for breast cancer, may trigger idiopathic SSc or morphoea and influence the severity of preexisting SSc, with the consequence that SSc is considered a relative contraindication to breast radiotherapy. In conclusion, cancer and SSc may be associated, but it is still controversial as to whether there is a causal relationship. Continuing interest in these associations, in particular in the different modalities of associations, may help to understand the underlying biological mechanisms and to identify patients at risk.
