This article reviews the diagnostic issues and the therapeutic management of small fibre neuropathy (SFN), and a detailed literature analysis of its association with primary Sjögren's syndrome (pSS). A diagnosis of SFN should be raised in the presence of diffuse neuropathic painful manifestations (burning sensation, paresthesia, pricking, allodynia or hyperesthesia) and neurovegetative signs. The neurological examination and the electroneuromyogram are usually normal. ⋯ The effectiveness of intravenous immunoglobulins is only supported by a few case reports. SFN deserves to be separately evaluated among pSS-associated peripheral neuropathies. This requires a better availability of the appropriate diagnostic procedures, the investigation of underlying immunopathological mechanisms and the assessment of the new treatments recently proposed in pSS, mainly rituximab.

Kidney involvement is frequent in hematologic malignancies. It is associated with adverse outcome and treatment difficulties. It can affect every area of the renal parenchyma (tubules, interstitium, glomerulus, vessels). ⋯ In this review, we detail the diagnostic tests that are needed for the detection and the follow-up of renal involvement in hematologic malignancies, and clarify the indications of renal biopsy. We propose diagnostic strategies of renal involvement in myeloma, Waldenström's disease, high grade lymphomas and acute leukemias, low grade lymphomas and chronic leukemias. The adverse effects of treatments (chemotherapy, radiotherapy, stem cell graft …) are not addressed in this review.

Review
[What are the new therapeutic strategies in metastatic colorectal cancer including biotherapies?].
Colorectal cancer remains one of the major causes of cancer death. Recent identification of new molecular targets led to the development of novel agents directed against growth factor receptors or key factors of angiogenesis. Recent phase III trials demonstrated a significant clinical benefit with bevacizumab, a VEGF inhibitor, and with EGFR-inhibitors, namely cetuximab and panitumumab. In this article we review the diverse treatment options combining cytotoxic and targeted therapies available for patients with metastatic colorectal cancer.

[Mesenchymal stem cells and immunomodulation: toward new immunosuppressive strategies for the treatment of autoimmune diseases?].
Mesenchymal stem cells (MSC) represent a population of the bone marrow microenvironment, which participates in the regulation of haematopoietic stem cells (HSC) self-renewal and differentiation. MSC are multipotent non-haematopoietic progenitors, which have been explored as a promising treatment in tissue regeneration. ⋯ Experimental and clinical data gave encouraging results, showing that MSC injection allowed controlling refractory GVHD, restoring bone development in children with osteogenesis imperfecta or improving heart function after myocardial infarction. Phase I-II studies are in progress in various countries to investigate the potential benefit from MSC due to their immunosuppressive properties, as an adjunctive therapy for severe refractory autoimmune disease.
