Anestesia regional intravenosa con anestésicos locales de larga duración. Actualización

Intravenous regional anesthesia is a widely used technique for brief surgical interventions, primarily on the upper limbs and less frequently, on the lower limbs. It began being used at the beginning of the 20th century, when Bier injected procaine as a local anesthetic. The technique to accomplish anesthesia has not changed much since then, although different drugs, particularly long-acting local anesthetics, such as ropivacaine and levobupivacaine in low concentrations, were introduced. Additionally, drugs like opioids, muscle relaxants, paracetamol, neostigmine, magnesium, ketamine, clonidine, and ketorolac, have all been investigated as adjuncts to intravenous regional anesthesia, and were found to be fairly useful in terms of an increased onset of operative anesthesia and longer lasting perioperative analgesia. The present article provides an overview of current knowledge with emphasis on long-acting local anesthetic drugs.     

Belgian community pharmacists’ pharmacovigilance perspective and practice

BackgroundPharmacovigilance legislation was introduced back in 2012 with new concepts such as the inverted black triangles and risk minimisation activities. Healthcare professionals need to familiarize themselves with these new notions in order to comply with their obligations such as risk mitigation and reporting of adverse drug reactions.ObjectiveTo measure the magnitude and relevance of these new concepts and the impact on everyday dispensing in Belgian community pharmacies.MethodsAn inventory database was constructed containing all relevant pharmacovigilance information at product level, and this data was made available within the pharmacy dispensing software. Furthermore, for a typical community pharmacy, the number of concerned products and the number of dispensed products with supplementary pharmacovigilance responsibilities was determined.ResultsThe number of available and dispensed medicines with black triangle or additional risk minimisation activities has increased significantly since July 2014. During July 2017, each pharmacy dispensed around 120 packs with risk minimisation obligations and around 70 with a black triangle, clearly illustrating the relevance of having all information at hand.ConclusionsWith relevant safety information available at the point of dispensing, pharmacists can now focus on complying with their pharmacovigilance responsibilities.

A Summary and Critical Assessment of the 2013 ACC/AHA Guideline on the Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Disease Risk in Adults: Filling the Gaps

The American College of Cardiology/American Heart Association (ACC/AHA) Task Force on Practice Guidelines has recently released the new cholesterol treatment guideline. This update was based on a systematic review of the evidence and replaces the previous guidelines from 2002 that were widely accepted and implemented in clinical practice. The new cholesterol treatment guideline emphasizes matching the intensity of statin treatment to the level of atherosclerotic cardiovascular disease (ASCVD) risk and replaces the old paradigm of pursuing low-density lipoprotein cholesterol targets. The new guideline also emphasizes the primacy of the evidence base for statin therapy for ASCVD risk reduction and lists several patient groups that will not benefit from statin treatment despite their high cardiovascular risk, such as those with heart failure (New York Heart Association class II-IV) and patients undergoing hemodialysis. The guideline has been received with mixed reviews and significant controversy. Because of the evidence-based nature of the guideline, there is room for several questions and uncertainties on when and how to use lipid-lowering therapy in clinical practice. The goal of the Mayo Clinic Task Force in the assessment, interpretation, and expansion of the ACC/AHA cholesterol treatment guideline is to address gaps in information and some of the controversial aspects of the newly released cholesterol management guideline using additional sources of evidence and expert opinion as needed to guide clinicians on key aspects of ASCVD risk reduction.     

Additional translocation (9;12)(p13;q24.1) in newly diagnosed chronic myeloid leukemia: complete cytogenetic remission after interferon therapy

We report the case of a patient with chronic phase CML who exhibited, in the same cells, beside the Philadelphia chromosome, an additional translocation between the other chromosome 9 and one of the chromosomes 12 [t(9;12)(p13;q24.1)]. Complete cytogenetic remission with disappearance of both karyotypic abnormalities was achieved after 18 months treatment with low dose (1.4 × 10⁶ U/m²/day) recombinant alpha-interferon and has been sustained with maintenance therapy for 68⁺ months (actual follow-up). Clonality at diagnosis and recovery of polyclonal hematopoiesis in complete cytogenetic remission were demonstrated using the polymorphism at the human androgen receptor gene (Humara) locus on chromosome X. The role of the additional translocation in the response to low dose alpha-interferon therapy remains hypothetical.
