Rheumatological conditions can sometimes present as emergencies. These can occur due to the disease process or infection; contrary to what many people think, rheumatologic emergencies like a pain, rheumatic crisis, or attack gout do not compromise the patient's life. This article mentioned only true emergencies: catastrophic antiphospholipid syndrome (cAPS), kidney-lung syndrome, central nervous system (CNS) vasculitis, anti-Ro syndrome (neonatal lupus), and macrophage activation syndrome (MAS). The management of above emergencies includes critical care, immunosuppression when indicated, and use of a diagnostic flowchart as well as fast laboratory profile for making decisions. Anticoagulants have to be used in the management of antiphospholipid syndrome. A good understanding of these conditions is of paramount importance for proper management. © 2015, International League of Associations for Rheumatology (ILAR). Source

The clinical practice guidelines for the prevention, diagnosis, evaluation and treatment of chronic kidney disease mineral and bone disorders (CKD-BMD) in adults, of the Latin American Society of Nephrology and Hypertension (SLANH) comprise a set of recommendations developed to support the doctor in the management of these abnormalities in adult patients with stages 3-5 kidney disease. This excludes changes associated with renal transplantation. The topics covered in the guidelines are divided into four chapters: 1) Evaluation of biochemical changes, 2) Evaluation of bone changes, 3) Evaluation of vascular calcifications, and 4) Treatment of CKD-MBD. The guidelines are based on the recommendations proposed and published by the Kidney Disease: Improving Global Outcomes (KDIGO) for the prevention, diagnosis, evaluation and treatment of CKD-MBD (KDIGO Clinical practice guidelines for the diagnosis, evaluation, prevention and treatment of Chronic Kidney Disease Mineral and Bone Disorder [CKD-MBD]), adapted to the conditions of patients, institutions and resources available in Latin America, with the support of KDIGO. In some cases, the guidelines correspond to management recommendations directly defined by the working group for their implementation in our region, based on the evidence available in the literature. Each chapter contains guidelines and their rationale, supported by numerous updated references. Unfortunately, there are few controlled studies with statistically sufficient weight in Latin America to support specific recommendations for the region, and as such, most of the references used correspond to studies carried out in other regions. This highlights the need to plan research studies designed to establish the current status of mineral and bone metabolism disorders in Latin America as well as defining the best treatment options for our population.

Current Rheumatology Reports | Year: 2016

The use of biologics has been associated with the paradoxical development of biologics-induced autoimmune diseases. The purpose of this review was to describe the key immunopathogenic mechanisms involved in the development of these conditions, and to discuss the clinical and laboratory characteristics usually described in the medical literature, reviewing case reports as well as records on national biologic therapies (BIOGEAS, RABBIT, BSRBR-RA, BIOBADAVEN). More than 200 cases have so far been reported, all of them diagnosed on the basis of the histopathology or meeting the ACR/Chapel Hill criteria. Over 75 % of the cases were females with a mean age of 48 ± 5 years. More than 50 % had rheumatoid arthritis. Most of the biologics-associated vasculitis developed in 90 ± 31 days. Complete resolution in almost 75 % of the cases was observed upon treatment discontinuation; however, steroid therapy was indicated for all patients and one death was recorded. The use of cyclophosphamide, rituximab or plasma exchange was reserved for the most severe cases. © 2016, Springer Science+Business Media New York. Source

Background: Macroscopic landmarks are lacking to identify the cavernosal nerves (CNs) during radical prostatectomy. The prostatic and capsular arteries run along the lateral border of the prostate and could help identify the location of the CNs during robot-assisted radical prostatectomy (RARP). Objective: Describe the visual cues that have helped us achieve consistent nerve sparing (NS) during RARP, placing special emphasis on the usefulness of the prostatic vasculature (PV). Design, setting, and participants: Retrospective video analysis of 133 consecutive patients who underwent RARP in a single institution between January and February 2011. Surgical procedure: NS was performed using a retrograde, antegrade, or combined approach. Measurements: A landmark artery (LA) was identified running on the lateral border of the prostate corresponding to either a prostatic or capsular artery. NS was classified as either medial or lateral to the LA. The area of residual nerve tissue on surgical specimens was measured to compare the amount of NS between the groups. Results and limitations: We could identify an LA in 73.3% (195 of 266) of the operated sides. The area of residual nerve tissue was significantly different whether the NS was performed medial (between the LA and the prostate) or lateral to the LA (between the LA and pelvic side wall): median (interquartile range) of 0 (0-3) mm 2 versus14 (9-25) mm 2; p < 0.001, respectively. Conclusions: The PV is an identifiable landmark during NS. Fine tailoring on the medial border of an LA can consistently result in a complete or almost complete NS, whereas performing the NS on its lateral border results in several degrees of incomplete NS. © 2011 European Association of Urology.

Leptin was characterized for the first time 20 years ago as an anorexigenic peptide that acts on the hypothalamus and has since been described as having a key role in the functioning of a great number of tissues. The mouth is one of the areas of the body where this peptide influences processes, such as growth induction and differentiation of various dental and periodontal tissues, modulation of sweet tastes’ perception in the taste buds, swallowing regulation and immune response activation. Moreover, leptin also plays an important role in mediating the response to different oral aggressors, such as periodontopathic bacteria and alcohol, as well as its involvement in certain types of mouth cancer. This review aims to provide an overview of leptin’s known roles on the oral cavity to date, ranging from its function in a healthy mouth to its involvement in oral physiopathology. © 2015, Instituto de Investigaciones Clinicas.
