Non tuberculous mycobacterial (NTM) infections, also called atypical mycobacterial infections, are caused by environmental mycobacteria and usually occur in cases of general or local immunosupression. These infections usually concern the lungs, the lymphatic system, the skin or the bones tissues. They are sometimes disseminated. In spite of new efficient antibiotics, including macrolides, therapeutic failures are common and favoured by long treatments with their potential adverse effects and drug interactions. ⋯ For those who are not locally or generally immunosupressed, it is important to search for an immunological deficiency. Indeed, patients having congenital deficiencies occurring in the interferon and interleukine pathways can develop repeated NTM infections. Therefore, for pulmonary infections in treatment failure and for disseminated infections, an adjuvant treatment by interferon gamma could be proposed. New molecules have recently been tested and can be used in some atypical mycobacterial infections.

Therapeutic erythrocytapheresis is a selective red cell-depletion aphaeresis technique. ⋯ Therapeutic erythrocytapheresis is a more modern and more effective method than the classic patient-bleeding. It has to be preferred in the early treatment of patients with polycythemia vera and hereditary hemochromatosis.

Clostridium difficile is an anaerobic gram positive, spore-forming bacterium which is responsible for 15-25% of antibiotic-associated diarrhea and for more than 95% of pseudomembranous colitis (PMC). This paper will review the main knowledge on C. difficile-associated infections and their recent evolution. ⋯ A systematic reporting of C. difficile incidence by health facilities should enable a better assessment of this pathology in France.

Typhlitis is a rare condition, characterized by necrotizing inflammation of the colon. It occurs mainly in neutropenic patients receiving chemotherapy for leukemia. ⋯ The pathological mechanisms of typhlitis remain unclear in neutropenic patients. The role of cytotoxic drugs as well as both bacterial overgrowth and translocation has been postulated. In our patient, asymptomatic reactivation of cytomegalovirus infection may have increased chemotherapeutic-agents-digestive toxicity.

We review the current knowledge about fibromyalgia, adding to the clinical aspects, the nosology, epidemiology and pathogenesis. The therapeutic and social management of these suffering patients are discussed. ⋯ Fibromyalgia is a clinical autonomous entity. Physiopathology knowledge is improving, but must be confirmed by new research. Patients will take profit of multimodal individualized treatment programs, including explanations about the diagnosis. In most cases, fibromyalgia is compatible with the maintenance of a professional activity, possibly adapted to the patient. Recognized disability requiring compensation is infrequent.
