This review is aimed at presenting classification and diagnosis criteria of hepatic porphyrias and at proposing guidelines for diagnosis and management of these diseases. ⋯ Treatment of acute attacks by hematin completely changed the disease prognosis. Relationships between porphyria cutanea tarda and hepatitis C virus or hemochromatosis have also been clarified. However, several important issues are still not solved: for instance, pathogenesis of neuronal dysfunction that produces the acute attacks is poorly understood. Differences related to susceptibility to develop acute attacks are not known.

The treatment of rheumatoid arthritis includes non-steroid anti-inflammatory drugs (NSAID), low-dose steroids and drugs which modify the evolution of the disease (disease modifying anti-rheumatic drugs, [DMARD]). In the last few years, the long-term efficiency of the recommended treatment strategies in rheumatoid arthritis has been a matter of debate and their basic assumptions have been challenged. Numerous studies were undertaken to settle the question. They tried to delineate the rules for an optimal use of current drugs and other therapeutic means. ⋯ At present, the tendency is to treat early and intensively, in order to obtain complete remission, improve evolution and reduce functional impairment. This strategy requires early diagnosis and early evaluation of prognosis of rheumatoid arthritis. Rheumatoid arthritis with benign evolution would not warrant intensive treatment. Studies are in progress to evaluate the prognostic factors in early rheumatoid arthritis that would enable us to adapt the strength of initial treatment to the disease's putative severity.

Following their use for a few years, the place of new macrolides can be assessed. ⋯ New macrolides have opened new avenues in the development of anti-infectious strategies. Due to their good efficacy against Chlamydia pneumoniae which is suspected of inducing vascular diseases, the upcoming use of ketolids and the development of their non-antibiotic effects, the future of macrolides is favorable.
