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.
