- Abstract
Lo zoster auricolare o herpes zoster oticus (HZO) è una patologia dell’orecchio causata dal virus della varicella o varicella zoster virus (VZV). Insorge dopo la riattivazione del virus latente all’interno del ganglio genicolato, a seguito di una diminuzione dell’immunità cellulare. Da un punto di vista epidemiologico, lo zoster auricolare rappresenta il 4,5% delle paralisi facciali periferiche. La diagnosi si basa sulla clinica. Nella sua forma tipica, si presenta come un’eruzione vescicolare nella conca e nel meato acustico esterno, associata a una paralisi facciale periferica; si parla, allora, di sindrome di Ramsay-Hunt. L’eruzione è associata a un’intensa otalgia e, di solito, precede la comparsa della paralisi facciale. In circa il 25% dei casi è presente un coinvolgimento cocleovestibolare; si parla, allora, di sindrome di Sicard. Può essere realizzata una risonanza magnetica, che mostra un’assunzione di segnale del nervo faciale principalmente a livello del ganglio genicolato. In caso di paralisi facciale grave, i test elettrici del nervo faciale consentono di valutare la prognosi di recupero. Il trattamento si basa sull’associazione di corticosteroidi e antivirali. La decompressione chirurgica del nervo faciale può essere proposta in caso di lesione grave con fattori prognostici sfavorevoli, ma le sue indicazioni devono essere attentamente valutate a causa dei rischi che essa comporta. La prognosi è principalmente legata al recupero della funzione facciale. Un recupero completo si verificherebbe nel 20% dei casi in assenza di trattamento. Possono persistere complicanze legate alla paralisi facciale, come le sincinesie.

- Abstract
El herpes zóster auricular o herpes zóster ótico (HZO) es una afección del oído causada por el virus de la varicela o virus varicela-zóster (VVZ). Se produce después de la reactivación del virus latente en el interior del ganglio geniculado, después de una disminución de la inmunidad celular. Desde un punto de vista epidemiológico, el herpes zóster ótico supondría el 4,5% de las parálisis faciales periféricas. El diagnóstico se basa en la clínica. En su forma típica, se presenta como una erupción cutánea vesicular en la concha y el conducto auditivo externo, asociado a una parálisis facial periférica; en tal caso, se habla de síndrome de Ramsay Hunt. La erupción se asocia a una otalgia intensa y suele preceder a la aparición de parálisis facial. En alrededor del 25% de los casos, existe una afectación cocleovestibular, en cuyo caso se habla de síndrome de Sicard. Se puede realizar una resonancia magnética, que muestra la captación de señal del nervio facial, sobre todo en el ganglio geniculado. En caso de parálisis facial grave, las pruebas eléctricas del nervio facial permiten evaluar el pronóstico de recuperación. El tratamiento se basa en una asociación de corticoides y antivirales. Se puede proponer la descompresión quirúrgica del nervio facial en caso de afectación grave que tenga factores de mal pronóstico, pero hay que sopesar bien sus indicaciones debido a los riesgos que conlleva. El pronóstico se relaciona sobre todo con la recuperación de la función facial. La recuperación completa se produciría en el 20% de los casos en ausencia de tratamiento. Pueden persistir complicaciones relacionadas con la parálisis facial, como sincinesias.

- Abstract
L’anémie préopératoire et la transfusion péri-opératoire sont des facteurs de risque de morbi-mortalité en chirurgie non cardiaque [1]. La chirurgie pour arthroplastie est un modèle en termes de chirurgie hémorragique. L’objectif de cette étude était double, déterminer le nombre de patients pouvant bénéficier d’une prescription de fer et/ou d’érythropoïétine (EPO), et déterminer un taux d’hémoglobine (Hb) préopératoire permettant d’éviter toute transfusion.

- Abstract
Background: In orthopedic surgery, a patient blood management program (PBM) has been proposed to reduce blood transfusion. The aim of this observational study was to assess, within a PBM, the specific efficacy of preoperative erythropoietin (EPO)., Study Design and Methods: In a single hospital, 723 patients undergoing elective primary hip or knee arthroplasty were prospectively studied. The PBM included EPO if preoperative hemoglobin was lower than 13 g/dL, intraoperative administration of tranexamic acid, use of recommended transfusion thresholds, and postoperative infusion of iron. Blood transfusion and hemoglobin were noted until discharge. Major thromboembolic or cardiovascular events were assessed during admission and 1 month after discharge., Results: Transfusion was noted in 2.5% patients with EPO. Transfusion rate was higher in patient for whom EPO was not indicated (13.6% transfusion rate; odds ratio [OR], 13.7; 95% confidence interval [CI], 2.6-66; p = 10
-3 ) or if erythropoietin was indicated but not administrated (36.8% transfusion rate; OR, 18.2; 95% CI, 3.9-84.5; p < 10-3 ). Hemoglobin was significantly higher during the postoperative period in patients with erythropoietin. At hospital discharge, 57% of patients were anemic if EPO was used compared to 88% when EPO was not indicated and 87% when EPO was indicated but not administered (p < 10-6 ). There were no significant differences in the odds of major complications between patients with or without EPO., Conclusions: Within a PBM, preoperative treatment of anemia with EPO decreased both the rate of blood transfusion and postoperative anemia. Further studies are necessary to confirm these results., (© 2020 AABB.)- Published

- Abstract
What We Already Know About This Topic: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Preoperative administration of epoetin-α with iron is commonly used in anemic patients undergoing major orthopedic surgery, but the optimal route of iron intake is controversial. The aim of this study was to compare the clinical effects of erythropoietin in combination with oral or intravenous iron supplementation., Methods: This study was a prospective, randomized, single-blinded, parallel arm trial. Patients scheduled for elective hip or knee arthroplasty with hemoglobin 10 to 13 g/dl received preoperative injections of erythropoietin with oral ferrous sulfate or intravenous ferric carboxymaltose. The primary endpoint was the hemoglobin value the day before surgery., Results: One hundred patients were included in the analysis. The day before surgery, hemoglobin, increase in hemoglobin, and serum ferritin level were higher in the intravenous group. For the intravenous and oral groups, respectively, hemoglobin was as follows: median, 14.9 g/dl (interquartile range, 14.1 to 15.6) versus 13.9 g/dl (interquartile range, 13.2 to 15.1), group difference, 0.65 g/dl (95% CI, 0.1 to 1.2; P = 0.017); increase in hemoglobin: 2.6 g/dl (interquartile range, 2.1 to 3.2) versus 1.9 g/dl (interquartile range, 1.4 to 2.5), group difference, 0.7 g/dl (95% CI, 0.3 to 1.1; P < 0.001); serum ferritin: 325 µg/l (interquartile range, 217 to 476) versus 64.5 µg/l (interquartile range, 44 to 107), group difference, 257 µg/l (95% CI, 199 to 315; P < 0.001). The percentage of patients with nausea, diarrhea, or constipation was higher in the oral group, 52% versus 2%; group difference, 50% (95% CI, 35 to 64%; P < 0.0001)., Conclusions: After preoperative administration of erythropoietin, body iron stores and stimulation of the erythropoiesis were greater with intravenous ferric carboxymaltose than with oral ferrous sulfate supplementation.
