Development and Validation of a Scoring System to Predict Response to Obeticholic Acid in Primary Biliary Cholangitis.

Background & Aims: Obeticholic acid (OCA) is the only licensed second-line therapy for primary biliary cholangitis (PBC). With novel therapeutics in advanced development, clinical tools are needed to tailor the treatment algorithm. We aimed to derive and externally validate the OCA response score (ORS) for predicting the response probability of individuals with PBC to OCA.

The submucosal approach influences long-term outcomes of refractory obstructive rhinitis: A prospective study and a STROBE analysis.

Objective: The surgical approach to refractory hypertrophy of the inferior turbinates is the main therapeutic choice in the management of its symptoms. Although submucosal approaches have demonstrated efficacy, long-term results are debated in the literature and show variable stability. Therefore, we compared the long-term outcomes of three submucosal turbinoplasty methods with regard to the efficacy and stability managing the respiratory disorders.

Diamine Oxidase Activity Deficit and Idiopathic Rhinitis: A New Subgroup of Non-Allergic Rhinitis?

Idiopathic rhinitis represents more than 50% of non-allergic rhinitis, a heterogeneous group that involves the symptomatic inflammation of the nasal mucosa. The TRPV1 receptor of unmyelinated C-type neurons appears to be involved in its pathophysiology. Histamine, whose main catabolic enzyme is DAO, is one of the mediators that can activate this receptor.

Long-term outcomes and cost-effectiveness of a magnet-based valve voice prosthesis for endoprosthesis leakage treatment.

Centenary of epidural anaesthesia.

March 2021 marked the first centenary of the publication of Fidel Pagés Miravé's seminal article Anestesia metamérica in the Revista Española de Cirugía. Pagés' knowledge of Bier and Tuffier's intradural (1889-1900) and Gil Vernet's sacral (1917-1918) techniques played a pivotal role in the development of the epidural anesthesia technique. Fidel Pagés' extensive experience with treating the casualties of armed conflicts, his proficiency in French and German, and his vast knowledge of anatomy, physiology and pharmacology lie behind the accuracy with which he describes the different approaches, the different anesthetic solutions, or the different instruments used, and the indications, contraindications and complications associated with his technique.

COVID-19 Pandemic and its Impact on the Management of Head and Neck Cancer in the Spanish Healthcare System.

 Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has represented a major challenge for healthcare systems worldwide, changing the habits of physicians. A reorganization of healthcare activity has been necessary, limiting surgical activity to essential cases (emergencies and oncology), and improving the distribution of health resources.  To analyze the impact of the COVID-19 pandemic on head and neck cancer surgery management in Spain.

Type 2N VWD: Conclusions from the Spanish PCM-EVW-ES project.

Introduction: Type 2N von Willebrand disease (VWD) is characterized by a decreased affinity of von Willebrand factor (VWF) for factor VIII (FVIII). Abnormal binding of FVIII to VWF (VWF:FVIIIB), results in low FVIII plasma levels, which can lead to a misdiagnosis of mild haemophilia A. Accurate diagnosis of type 2N VWD is essential for appropriate genetic counselling and therapy.

Advances in multimodal treatment for stage IIIA-N2 non-small cell lung cancer.

Background And Aim: In Stage IIIA-N2 non-small cell lung cancer (NSCLC), the accuracy of combined positron-emission tomography/computed tomography imaging (PET-CT), together with mediastinal staging techniques, has led to a wide range of challenging clinical scenarios in terms of therapeutic management. Concurrent chemoradiotherapy followed by consolidation immunotherapy remains the standard of care. In patients with potentially-resectable disease, surgery plays an important role in multimodal therapy.

Involvement of Laryngopharyngeal Reflux in Ocular Diseases: A State-of-the-Art Review.

Background: Laryngopharyngeal reflux-associated symptoms embrace a wide variety of head and neck manifestations. Its participation in eye disorders has recently been postulated, and there is currently no consensus in this regard. The aim of this manuscript is to review the role of reflux in the development of ocular signs and symptoms, and its physio-pathological mechanisms.

Validity and reliability of the COVID-19 symptom index, an instrument evaluating severity of general and otolaryngological symptoms.

Background: There is no clinical instrument evaluating symptoms of COVID-19.

Objective: To develop a clinical instrument for evaluating symptoms of COVID-19 mild-to-moderate forms.

Methods: COVID-19 patients were recruited from EpiCURA Hospital (Belgium).

Deep inferior epigastric artery perforator free flap in head and neck reconstruction: A systematic review.

Background: Perforator flaps yield the best results for the patient with the least morbidity, and they should be considered the gold standard in head and neck reconstruction. Although deep inferior epigastric perforator (DIEP) flap is considered as the gold standard in breast reconstruction, its use in head and neck reconstructive surgery does not seem so widespread. The objective of this study is to conduct a systematic review of the use, applications and results of the DIEP flap in the head and neck area.

High-dose neoadjuvant chemoradiotherapy versus chemotherapy alone followed by surgery in potentially-resectable stage IIIA-N2 NSCLC. A multi-institutional retrospective study by the Oncologic Group for the Study of Lung Cancer (Spanish Radiation Oncology Society).

Background: The optimal induction treatment in potentially-resectable stage IIIA-N2 NSCLC remains undefined.

Aim: To compare neoadjuvant high-dose chemoradiotherapy (CRT) to neoadjuvant chemotherapy (CHT) in patients with resectable, stage IIIA-N2 non-small-cell lung cancer (NSCLC).

Methods: Retrospective, multicentre study of 99 patients diagnosed with stage cT1-T3N2M0 NSCLC who underwent neoadjuvant treatment (high-dose CRT or CHT) followed by surgery between January 2005 and December 2014.

Is the ultrasonic scalpel recommended in head and neck surgery during the COVID-19 pandemic? State-of-the-art review.

Background: Guidelines for ultrasonic devices use are imperative because infectious aerosols arising from airway procedures were a key etiologic factor in prior coronavirus outbreaks. This manuscript aims to summarize the available recommendations and the most relevant concepts about the use of ultrasonic scalpel during the SARS-CoV-2 pandemic.

Methods: Literature review of manuscripts with patients, animal models, or in vitro studies where the ultrasonic scalpel was used and the plume produced was analyzed in a quantitative and/ or qualitative way.

Unraveling the Influence of Common von Willebrand factor variants on von Willebrand Disease Phenotype: An Exploratory Study on the Molecular and Clinical Profile of von Willebrand Disease in Spain Cohort.

The clinical diagnosis of von Willebrand disease (VWD), particularly type 1, can be complex because several genetic and environmental factors affect von Willebrand factor (VWF) plasma levels. An estimated 60% of the phenotypic variation is attributable to hereditary factors, with the ABO blood group locus being the most influential. However, recent studies provide strong evidence that nonsynonymous single nucleotide variants (SNVs) contribute to VWF and factor VIII phenotypic variability in healthy individuals.

Use of double flange voice prosthesis for periprosthetic leakage in laryngectomised patients: A prospective case-crossover study.
