Cancer risk in immune-mediated inflammatory diseases (IMID).

Inflammation and cancer have a profound yet ambiguous relationship. Inflammation - especially chronic inflammation - has protumorigenic effects, but inflammatory cells also mediate an immune response against the tumor and immunosuppression is known to increase the risk for certain tumors.This article reviews current literature on the role of inflammation in cancer and the cancer risk in immune-mediated inflammatory diseases (IMIDs).

The influence of ageing on the development and management of rheumatoid arthritis.

The population of elderly individuals with rheumatoid arthritis (RA) is expanding, due mainly to increasing life expectancy. A variety of theories have been proposed to explain the ageing process, including accumulation of DNA damage and resultant changes in biological processes. Such changes can influence the development and/or course of disease.

Management of inflammatory bowel disease in pregnancy.

Background And Aims: Inflammatory bowel disease (IBD) is a chronic disease affecting mainly young people in their reproductive years. IBD therefore has a major impact on patients' family planning decisions. Management of IBD in pregnancy requires a challenging balance between optimal disease control and drug safety considerations.

Rheumatoid arthritis and pregnancy: evolution of disease activity and pathophysiological considerations for drug use.

It has long been known that pregnancy and childbirth have a profound effect on the disease activity of rheumatic diseases. For clinicians, the management of patients with RA wishing to become pregnant involves the challenge of keeping disease activity under control and adequately adapting drug therapy during pregnancy and post-partum. This article aims to summarize the current evidence on the evolution of RA disease activity during and after pregnancy and the use of anti-rheumatic drugs around this period.

Vaccinations in patients with immune-mediated inflammatory diseases.

Patients with immune-mediated inflammatory diseases (IMID) such as RA, IBD or psoriasis, are at increased risk of infection, partially because of the disease itself, but mostly because of treatment with immunomodulatory or immunosuppressive drugs. In spite of their elevated risk for vaccine-preventable disease, vaccination coverage in IMID patients is surprisingly low. This review summarizes current literature data on vaccine safety and efficacy in IMID patients treated with immunosuppressive or immunomodulatory drugs and formulates best-practice recommendations on vaccination in this population.

Quality control techniques for routine analysis with liquid chromatography in laboratories.

The process of quality assurance should demonstrate that the method and the analytical instrument provide accurate and precise results, or whether deterioration occurs. For this, the quality procedure should include tests which provide information on the characteristic performance of the method. According to the recent literature, useful procedures contributing to the overall quality of analytical results are illustrated in relation with liquid chromatography.

Direct determination of major elements in solid plant materials by electrothermal vaporization inductively coupled plasma atomic emission spectrometry.

The present work demonstrates the capability of electrothermal vaporization (ETV) to become an important tool of solid sample introduction in ICP-AES for plant sample analysis. Direct determination of Al, Ca, Fe, K, Mg, Mn, Na and Zn was investigated in powdered plant samples. Obtaining good results for major elements in plant samples was governed by some special operating conditions.
