High tumor markers were frequently found in RA patients, even with controlled disease and were not related to actual cancer. Therefore, small increases of these markers in RA cases probably do not warrant a search for an occult neoplasm.

Sjogren's syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of the exocrine glands and other organs. Women with SS often experience gynecological symptoms due to the disease and need extra care regarding their sexual activity, reproductive health and during pregnancy, conditions that are not properly conducted in the clinical practice. To cover this gap, a panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis on the identification of symptoms, diagnosis, monitoring, prognosis, and treatment of these manifestations. A Focus Group meeting was held and included experts in the field and methodologists, based on a previously developed script, with themes related to the objective of the study. The most important topics were summarized and 11 recommendations were provided.

Hypertrophic osteoarthropathy (HOA) is characterized by periostitis of tubular bones, thickened skin, and digital clubbing. Its pathogenesis is unknown but an inflammatory factor and increased bone remodeling have been implicated. It is a very rare disease, usually diagnosed late with few therapeutic options. Bone and joint pains are secondary to periostitis and are usually difficult to control. Tumor necrosis factor-alpha is a cytokine that induces other inflammatory cytokine production, has an osteoclastogenic effect in different rheumatic diseases and probably also has an important role in periostitis and the systemic inflammatory manifestations in HOA. We describe the case of a patient with the primary form of HOA, who had refractory bone pain and arthritis that responded partially to infliximab treatment.

Chronic use of cocaine by inhalation may induce midline destructive lesions (CIMDL), which can sometimes be diffi cult to distinguish from the ear, nose and throat lesions of Wegener's Granulomatosis (WG). We describe the case of a 43-year-old female patient admitted with a two-year history of nasal obstruction and rhinorrhea. She had been diagnosed with WG for fi ve months, being on prednisone and cyclophosphamide. On her physical examination, perforation of her nasal septum and palate was observed. Laboratory tests showed elevated acute phase proteins and a positive p-ANCA test. ELISA assays anti-proteinase 3 and myeloperoxidase were negative. The paranasal sinus computed tomography (CT) showed destruction of the nasal septum and palate, in addition to bilateral maxillary sinusitis. Chest CT was normal. Nasal mucosal biopsy revealed an infl ammatory infi ltrate, with neither granuloma nor vasculitis. When questioned, she admitted being a cocaine user for fi ve years. Medical therapy and cocaine use were withdrawn. She has been followed up for six months and no other lesion or other organ symptoms occurred. Differential diagnosis in patients with midline destructive lesions can be very challenging. Evaluation should include enquiry about intranasal use of cocaine. Although ANCA testing does not clearly differentiate the ANCA found in some patients with CIMDL from those found in WG patients, the localized involvement and the biopsy fi ndings non-characteristic of small vessel granulomatous vasculitis should be recognized as features for cocaine-induced lesions.
