Resumen Introduccion La implantacion unilateral en la hipoacusia profunda bilateral deja al paciente en una situacion de audicion monoaural, con los consiguientes problemas audiologicos, en especial por la incapacidad de percepcion de la palabra en ambientes con ruido de fondo, por el efecto sombra de la cabeza. Se puede mejorar su rendimiento auditivo aprovechando los sistemas inalambricos de enrutamiento de la senal (CROS), para dotarlos de una entrada de sonido bilateral. Metodo Se estudiaron 12 usuarios unilaterales de implante coclear adultos, con experiencia con un procesador de sonido Naida C I Q70 que tiene capacidad de comunicacion inalambrica con el CROS. La comprension del habla en cabina en silencio y en ruido se llevo a cabo utilizando como estimulos el test de oraciones grabadas en espanol en 3 condiciones: habla dirigida hacia el oido no implantado con y sin CROS activado y habla de frente con UltraZoom. Tras un mes de uso del dispositivo CROS, se evaluo la satisfaccion del usuario utilizando cuestionarios. Resultados En silencio, la diferencia media entre el implante unilateral solo y el implante unilateral con el dispositivo CROS fue del 27,6%, mientras que en presencia de ruido fue del 32,5%. Si se comparan las puntuaciones entre presentar activada o no la opcion UltraZoom al utilizar CROS, se demuestra un beneficio de un 35% de inteligibilidad. Todos los sujetos puntuaron su experiencia de uso como satisfactoria. Conclusion El dispositivo CROS utilizado con implante coclear unilateral produce un beneficio objetivo y subjetivo en el reconocimiento de la palabra cuando la senal se dirige hacia el mismo. En este estudio no se reprodujo la condicion de presentacion de la senal verbal en el oido implantado con ruido en el adaptado con el CROS por haberse demostrado previamente que la discriminacion verbal se deteriora de forma importante con respecto al implante unilateral sin CROS.

Introdution Single cochlear implantation usually provides substantial speech intelligibility benefits but bilaterally deaf, unilaterally implanted subjects will continue to experience limitations due to the head shadow effect, like single-sided deaf individuals. In the treatment of individuals with single-sided deafness one option is contralateral routing of signal (CROS) devices, which constitute a non-surgical intervention of the second ear in unilaterally implanted individuals. Method Twelve experienced adult cochlear implant (CI) users with Naida Q70 processor and the CROS device used in combination participated in the study. For the study three conditions were provided: CI only, omnidirectional microphone mode (CROS deactivated); CI plus CROS activated, omnidirectional microphone mode and CI plus CROS activated, UltraZoom mode. Speech reception thresholds were determined in quiet and noise. Subjective feedback regarding the practical usability of the CROS device and the perceived benefit were collected. Results There was a 27.6% improvement in speech understanding in quiet and 32.5% improvement in noise when CROS device was activated. Using advanced directional microphones, a statistically significant benefit of 35% was obtained. The responses to the questionnaires revealed that the subjects perceived benefit in their everyday lives when using the CROS device with their CI. Conclusion The investigated CROS device used by unilateral CI recipients in cases where bilateral implantation is not an option provides both subjective and objective speech recognition benefit when the signal is directed to the CROS device. Unfavourable conditions where speech is presented from the CI side and noise from the CROS side or diffusely were not included in this evaluation since the CROS device adds additional noise and performance is expected to decrease as has previously been shown.

Introduction Sensorineural hearing loss (SNL) is the most prevalent sensory deficit in our environment. The next generation genomic sequencing (NGS) allows to obtain an etiological diagnosis in a high percentage of patients. Our pilot study shows the results of the systematic application of NGS in a Childhood Hearing Loss Unit, as well as its implications in the clinical management of patients and their families. Material and method We included 27 patients diagnosed with SNH between 2014 and 2017, in which an environmental cause was ruled out. The genetic test consisted of a panel of genes analyzed by NGS (OTOgenics™ panel). This panel has been designed to include genes associated with sensorineural or mixed hearing loss, early onset or late, syndromic and non-syndromic, regardless of their inheritance pattern. Results A genetic diagnosis was obtained in 56% (15/27) of the patients (62% in the case of bilateral HNS). 5/27 (19%) presented pathogenic variants in the GJB2 gene and the rest variants pathogenic and/or probably pathogenic in other genes associated with isolated HNS (PR2 × 2, TECTA and STRC), with syndromic HNS (CHD7, GATA3, COL4A5, MITF and SOX10) or with syndromic and non-syndromic HNS (BSND, ACTG1 and CDH23). Discussion The etiological diagnosis of SNL is a challenge in clinical practice. Our series demonstrates that it is possible to implement genetic diagnosis in the daily routine and that this information has prognostic and therapeutic implications.

Resumen Antecedentes y objetivo El riesgo de meningitis bacteriana aumenta en los pacientes con implante coclear. Por ello, se indica la vacunacion antineumococica, antigripal y frente a Haemophilus influenzae tipo b en este grupo. El objetivo del presente estudio es conocer el cumplimiento del calendario vacunal en los pacientes implantados en un hospital de referencia. Materiales y metodos Se incluyeron los pacientes con implante coclear intervenidos entre 2005 y 2015. Se evaluaron las coberturas vacunales frente a gripe estacional, Haemophilus influenzae tipo b, neumococo conjugada de 13 serotipos y neumococo polisacarida de 23 serotipos. Se dividio la muestra en 2 grupos por edad ( Resultados De los 153 pacientes estudiados (28,01% 0-13 anos y 71,9% ≥ 14), solo 2 (5,71%) tuvieron un 100% de adherencia al calendario vacunal, mientras que el 65,71% registro un cumplimiento del 50% o menor. Globalmente, la cobertura de vacunacion frente a la pauta secuencial de neumococo fue del 48,57%. La poblacion pediatrica supero el 90% de cobertura para la vacuna frente a Haemophilus influenzae tipo b y neumococo conjugada de 13 serotipos, mientras que en los mayores de 14 anos apenas supero el 50%. La cobertura frente a gripe estacional fue inferior al 40%. Se obtuvo una correlacion inversa entre la edad y el cumplimiento, aunque no estadisticamente significativa. Conclusiones Las coberturas de vacunacion en los pacientes con implante coclear evaluados son mas bajas de lo esperado. Se propone la colaboracion estrecha entre los servicios de Otorrinolaringologia y las Unidades de Vacunas como principal estrategia para la mejora.

The risk of bacterial meningitis increases in cochlear implant patients. Therefore, pneumococcal, influenza and Haemophilus influenzae type b vaccination is indicated in this group. The aim of this study was to determine compliance with the vaccination calendar in patients implanted in a referral hospital.Patients with cochlear implant operated between 2005 and 2015 were included. Vaccine coverage for seasonal influenza, Haemophilus influenzae type b and pneumococcal conjugate 13-serotypes and pneumococcal polysaccharide 23-serotypes was evaluated. The sample was divided into 2 age groups (14 years and≥14 years). A univariate and bivariate analysis was performed.Of the 153 patients studied (28.01% 0-13 years old and 71.9%≥14), only 2 (5.71%) had 100% adherence to the vaccination schedule, while 65.71% had compliance of 50% or less. Overall, vaccination coverage against the sequential pneumococcal pattern was 48.57%. The paediatric population exceeded 90% coverage for the vaccine against Haemophilus influenzae type b and pneumococcal conjugate 13-serotypes while in those over 14 years of age it barely exceeded 50%. Influenza coverage was less than 40%. An inverse correlation was obtained between age and compliance, although not statistically significant.Vaccination coverage in patients with cochlear implant is lower than expected. Close collaboration between Otolaryngology departments and the Vaccination Units is proposed as the main strategy for improvement.

Resumen Introduccion y objetivos La inadecuada retroalimentacion auditiva en los ninos con hipoacusia prelocutiva altera la articulacion de consonantes y vocales. El proposito de esta investigacion es comparar la produccion de vocales en ninos hipoacusicos hispanohablantes con implante coclear o adaptacion audioprotesica con ninos normooyentes por medio del analisis acustico de las frecuencias formanticas y el espacio vocal. Metodo Un total de 56 ninos con hipoacusia prelocutiva (25 con implante coclear y 31 con audifonos) y 47 ninos normooyentes participaron en el estudio. Los 2 primeros formantes (F1 y F2) de las 5 vocales del idioma espanol se midieron utilizando el programa Praat. Para analizar las diferencias entre los 3 grupos se aplico el metodo ANOVA de analisis de la varianza y el test de Scheffe. Tambien se calculo el area del espacio vocal. Resultados El valor medio del F1 en todas las vocales no mostro diferencias significativas en los 3 grupos de ninos. Para las vocales /i/, /o/ y /u/ el valor medio del F2 fue significativamente diferente entre los 2 grupos de ninos hipoacusicos y el grupo de ninos normooyentes. Conclusion Ambos grupos de ninos con hipoacusia prelocutiva tienden a presentar sutiles desviaciones en la articulacion de las vocales que pueden ser analizadas mediante un programa de analisis acustico.

Resumen Introduccion y objetivos El tratamiento principal de los carcinomas diferenciados de tiroides es la cirugia seguida de radioyodo. El proposito de este estudio es exponer nuestra experiencia en el manejo de estos tumores. Material y metodo Se presenta un estudio retrospectivo de los 55 pacientes intervenidos quirurgicamente de un carcinoma diferenciado de tiroides en nuestro hospital entre los anos 2007 y 2011. Resultados La edad media al diagnostico fue de 49 anos, con un predominio femenino (78% de los casos). El 78% de los pacientes se encontraban en fases iniciales (estadios i y ii ). El diagnostico histopatologico definitivo fue de carcinoma papilar en el 84% y folicular en el 16% restante. A todos, salvo a 2 pacientes (4%), se les realizo una tiroidectomia total, acompanada de linfadenectomia en el 58% de los casos. Un 9% de los pacientes presento hipoparatiroidismo permanente y aunque un 18% sufrio paralisis recurrencial unilateral transitoria, un 40% de ellos se recupero completamente a los 6 meses. Se administro radioyodo en el postoperatorio al 89% de los pacientes. Se produjo un 40% de recidivas, la mayor parte de las cuales (29% de los pacientes) se localizaron a nivel cervical. La supervivencia a los 5 anos fue del 87%, siendo del 95% en el subtipo papilar y descendiendo al 56% en el folicular (p = 0,001). Discusion/conclusiones Los carcinomas diferenciados de tiroides son tumores con un pronostico excelente tras un tratamiento quirurgico adecuado previa valoracion preoperatoria exhaustiva y seguimiento postoperatorio estricto debido a las tasas significativas de recidiva.

Resumen Introduccion y objetivos La fiabilidad de las calificaciones perceptuales de la calidad global de la voz y sus dimensiones especificas es dificil de alcanzar, por cuanto estos juicios dependen de la subjetividad del examinador. De este modo, la busqueda de unas medidas clinicas que sean objetivas, validas y accesibles es una prioridad para incluirlas en los protocolos de evaluacion de la voz. El proposito del presente estudio fue: 1) determinar la exactitud diagnostica de un unico parametro acustico, la prominencia del pico cepstral suavizado (CPPS), para predecir la presencia y severidad de una disfonia en vocales sostenidas y habla conectada utilizando el programa Praat; 2) determinar la relacion entre las medidas del CPPS y las calificaciones perceptuales de la calidad vocal; y 3) describir los valores normativos del CPPS. Metodo Se obtuvo el valor del CPPS de muestras vocales sostenidas y de habla conectada de 72 sujetos hispanohablantes con trastornos vocales y de 52 sujetos hispanohablantes sanos utilizando el programa Praat. Se llevo a cabo un estudio estadistico completo utilizando el programa SPSS de IBM version 23. Resultados Se encontro una sensibilidad de un 70% y una especificidad de un 85%. La severidad estimada de la voz, tanto en vocal sostenida como en habla conectada, se correlaciono de forma importante con las calificaciones perceptuales de severidad global de la disfonia. Conclusiones Un parametro acustico unico, el CPPS calculado mediante el programa Praat, predice de forma importante el estatus de un trastorno vocal. Se considera la incorporacion del CPPS para complementar la valoracion clinica de la voz.

Introduction and objectives Perceptual rating of overall voice quality and other more specific perceptual dimensions is difficult, as such judgments depend on the listener's subjectivity. Thus, finding objective, valid, and accessible clinical measures to include in comprehensive voice evaluation protocols is a priority. The purposes of this study were to (1) determine the diagnostic accuracy of a single acoustic measure, smoothed cepstral peak prominence (CPPS), to predict voice disorder status from sustained vowels and connected speech samples using the software Praat; (2) to determine the relationship between measures of CPPS and perceptual ratings of vocal quality; and (3) describe the normative values of CPPS. Method Measures of CPPS were obtained from connected speech and sustained vowel recordings of 72 Spanish-speaking subjects with voice disorders and 52 nondysphonic Spanish-speaking subjects with no vocal disorders using freely downloadable Praat software. IBM SPSS Statistics software version 23 was used to complete the statistical analyses. Results Results revealed a 70% sensitivity rate, a specificity rate of 85%. Estimated severity for sustained vowels and connected speech were strongly correlated and significantly associated with listener ratings of dysphonia severity. Conclusions A single acoustic measure of CPPS was highly predictive of voice disorder status using Praat software. Clinicians may consider using CPPS to complement clinical voice evaluation and screening protocols.

Objective The objective was to determine the results of the treatment of severe and/or refractory epistaxis requiring hospital admission. In addition, the results of arterial ligation versus embolisation were compared. Material and method Sixty-three patients with severe and/or refractory epistaxis requiring hospital admission between August 2014 and December 2016 were included prospectively. Results Eleven patients (17%) underwent embolisation, 5 (8%) endoscopy ligation and the remaining 47 (75%) underwent conservative treatment with tamponade. The mean age of the patients in which conservative measures were sufficient was 72 years, while the age of those treated with embolisation was 71 years and of those who underwent surgery was 53 years. For the patients who underwent conservative treatment or surgery, the average stay was 6 days, compared to 9 days for those who underwent embolisation. One patient suffered a hemispheric stroke after embolisation. No post-surgical complications were observed. Conclusions Most cases of severe and/or refractory epistaxis are resolved by conventional tamponade. Endoscopy ligation is associated with a decrease in hospital stay, without serious complications. It is advisable to have all the possible therapeutic options available, for which the presence of interventional radiologists and experienced surgeons is essential to avoid complications and decide the treatment to be performed individually for each patient.

Resumen Introduccion y objetivos El objetivo fue determinar los resultados del tratamiento de las epistaxis graves y/o refractarias que requirieron ingreso hospitalario. Ademas se compararon los resultados del tratamiento mediante ligadura arterial o embolizacion. Material y metodo Se incluyeron de forma prospectiva 63 pacientes con epistaxis grave y/o refractaria que requirieron ingreso hospitalario entre agosto de 2014 y diciembre de 2016. Resultados En 11 pacientes (17%) se realizo embolizacion, 5 (8%) fueron intervenidos mediante endoscopia y en los 47 restantes (75%) se realizo tratamiento conservador. La edad media de los pacientes en los que las medidas conservadoras fueron suficientes fue de 72 anos, mientras que la edad de aquellos tratados con embolizacion fue de 71 anos y de los que fueron intervenidos quirurgicamente fue de 53 anos. En los pacientes sometidos a tratamiento conservador o a cirugia la estancia media fue de 6 dias, frente a 9 dias en aquellos en los que se realizo embolizacion. Un paciente sufrio un ictus hemisferico tras la embolizacion. No se observaron complicaciones posquirurgicas. Conclusiones La mayoria de los pacientes con epistaxis graves y/o refractarias se resuelven mediante taponamiento convencional. El tratamiento mediante ligadura arterial esta asociado a una disminucion de la estancia hospitalaria, sin observarse complicaciones graves. Es aconsejable disponer de todas las opciones terapeuticas posibles para lo cual la presencia de radiologos intervencionistas y cirujanos experimentados es fundamental para evitar complicaciones y decidir el tratamiento a realizar de forma individual en cada paciente.

Resumen Antecedentes y objetivos Los angiofibromas juveniles (AJ) son tumores benignos cuyo tratamiento de eleccion es la cirugia. Dada su localizacion y su comportamiento expansivo pueden generar una elevada morbilidad. Tienen gran tendencia al sangrado y su tratamiento es complejo. El manejo de los AJ ha cambiado, pero continua siendo un reto. El objetivo de este estudio fue revisar a una serie de pacientes con AJ tratados mediante un abordaje endonasal endoscopico endonasal. Material y metodos Se revisaron las historias medicas de todos los pacientes con AJ intervenidos mediante un abordaje endoscopico endonasal. Las principales variables estudiadas incluyeron el estadio tumoral, la perdida de sangre intraoperatoria, la tasa de complicaciones y la tasa de persistencia o recidiva. Resultados Se incluyeron un total de 31 pacientes, 30 varones y una mujer. La edad media fue de 17 anos. Segun la clasificacion de Radkowski, un caso pertenecia al estadio I, 5 al estadio IIA, 9 al estadio IIB, 4 al estadio IIC, 10 al estadio IIIA y 2 al estadio IIIB. El 39% de los AJ pertenecian a estadios avanzados (IIIA y IIIB). La perdida media de sangre fue de 1.156 ml. Excepto en un caso, no se observaron complicaciones significativas. La tasa de persistencia/recurrencia al finalizar el seguimiento fue del 6% (2 AJ en estadio avanzado). El seguimiento medio fue de 86 meses. Conclusiones Este estudio retrospectivo respalda que la opcion de los abordajes endoscopicos endonasales para el tratamiento de los AJ es factible y se asocia con buenos resultados a largo plazo.

Introduction Contralateral sensorineural hearing loss (CSNHL) after vestibular schwannoma (VS) is a severe complication, especially in those cases in which hearing preservation in the operated side was not possible. There are several theories that attempt to explain this issue, but there is no established guideline of treatment. Material and methods We report 4 patients treated in our institution who developed a severe CSNHL after surgery. Results Of the 185 cases of VS treated with surgery, 4 patients (2.2%) developed a CSNHL after VS surgery. After medical treatment, partial recovery of hearing occurred in one patient the other 3 patients presented a well-established severe SNHL. Conclusions Established treatment guidelines do not exist, but the use of high doses of corticosteroids has been recommended and cochlear implant in cases with no recovery and complete hearing loss may be useful.

Background and Objectives Juvenile angiofibroma (JA) is a benign tumour, for which the treatment of choice is surgery. It may be associated with significant morbidity because of its anatomical location and its locally destructive growth pattern. Severe haemorrhage constitutes a high risk in JA and its surgical management can be complex. The management of JA remains a challenge. The objective of this study was to review a series of patients with JA treated via the endonasal/endoscopic approach. Material and Methods Medical records of patients operated for JA were reviewed. Main outcome measures: tumour stage, intraoperative blood loss, complications and persistence/recurrence rates. Results A total of 30 male patients and one female were included. The mean age was 17 years. Using the Radkowski classification, one JA was classified as stage I, 5 stage IIA, 9 stage IIB, 4 stage IIC, 10 stage IIIA and 2 stage IIIB. Thirty-nine percent of the JA was classified as advanced stage JA (IIIA and IIIB). The mean blood loss was 1.156 mL except in one case, no significant complications were observed. Tumour persistence/recurrence was observed in 2 JA (6%), at the end of the follow-up. Mean postoperative follow-up time was 86 months. Conclusions This retrospective study supports the notion that endonasal endoscopic approaches for a JA are a feasible option associated with good long-term results.

Resumen Antecedentes y objetivos En estudios previos hemos indicado que EGFR tiene un papel en la carcinogenesis en un subgrupo de carcinomas epidermoides nasosinusales (CENS). Ademas, EGFR activa a 2 de las mas importantes vias de senalizacion intracelular como son la PI3K/pAKT/mTOR/pS6 y la via MAP-cinasas. El objetivo de este estudio fue evaluar la participacion de la ruta de EGFR/PI3K/pAKT/mTOR/pS6 y su relacion con parametros clinico-patologicos y de seguimiento de los CENS. Material y metodos La expresion proteica de PTEN, pAKT, mTOR y pS6 fue analizada mediante inmunohistoquimica en 54 CENS. Los resultados fueron relacionados con diversos parametros clinico-patologicos y la supervivencia. Resultados La perdida de expresion de PTEN se observo en 33/54 casos (61%) y la sobreexpresion de pAKT, mTOR y pS6 se observo en 19/54 casos (35%), 8/54 casos (15%) y 47/54 casos (87%), respectivamente. La perdida de expresion de PTEN se relaciono con la invasion intracraneal y el desarrollo de metastasis regionales (p = 0,005). La ausencia de sobreexpresion de pS6 se relaciono con una supervivencia especifica (p = 0,008) y global (p = 0,007) mas favorables y la ausencia de recidivas locales (p = 0,055). No se observaron relaciones significativas entre la expresion de pAKT y mTOR y los parametros clinico-patologicos estudiados. Conclusiones Las alteraciones en la expresion de los componentes de la via EGFR/PI3K/pAKT/mTOR/pS6 son frecuentes en un subgrupo de CENS. Este estudio revela que la ausencia de sobreexpresion de pS6 se relaciona con mejores resultados clinicos, por lo que la expresion pS6 podria considerarse como un marcador pronostico.

Resumen Introduccion y objetivos La quimiorradioterapia es el tratamiento de eleccion del carcinoma de nasofaringe. Las recurrencias locales son una de las principales causas de mortalidad en estos pacientes: el rescate quirurgico o la reirradiacion son el tratamiento de eleccion, segun la disponibilidad. El objetivo fue evaluar y comparar los resultados de la cirugia de rescate en el tratamiento de las recidivas locales de los carcinomas nasofaringeos mediante abordajes abiertos vs. endoscopicos. Metodos Veinte pacientes con recidivas locales de carcinomas nasofaringeos fueron intervenidos quirurgicamente: 12 pacientes fueron intervenidos mediante cirugia abierta y 8 mediante un abordaje endoscopico endonasal transpterigoideo. Un paciente fue estadiado como rT1; 3 como rT2; 2 como rT3 y 6 como rT4 en el grupo de abordajes abiertos; en la serie endoscopica, 2 pacientes fueron rT1, 5 fueron rT2 y uno fue rT3. Resultados En 3 de los pacientes (25%) intervenidos mediante cirugia abierta (un rT4, un rT3 y un rT2) no se logro una reseccion macroscopica completa). En el grupo endoscopico la reseccion fue completa en todos los pacientes. La tasa de complicaciones en el grupo intervenido mediante abordajes abiertos fue del 92% (5 complicaciones leves, 5 complicaciones moderadas y una complicacion grave) y en el grupo intervenido mediante endoscopia fue del 100% (7 sufrieron complicaciones leves y un paciente una complicacion grave). La supervivencia a los 3 y 5 anos fue del 53 y del 42% en el abordaje abierto y del 100 y del 75% en el abordaje endoscopico, respectivamente. Conclusiones Los abordajes endoscopicos disminuyen la morbilidad asociada a los abordajes abiertos y permiten obtener un control oncologico favorable.

Background Rheumatoid arthritis (RA) is a complex inflammatory disease that modifies body composition. Although body mass index (BMI) is one of the clinical nutrition tools widely used to assess indirectly nutritional status, it is not able to identify these body alterations. Bioelectrical Vector Analysis (BIVA) is an alternative method to assess hydration and body cell mass of patients with wasting conditions. Objective To investigate the differences in nutrition status according to BMI groups (normal, overweight and obesity) and BIVA classification (cachectic and non-cachectic) in women with RA. Methods Women with confirmed diagnosis of RA were included from January 2015 to June 2016. Whole-body bioelectrical impedance was measured using a tetrapolar and mono-frequency equipment. Patients were classified according to BMI as: low body weight (n = 6, 2.7%), normal (n = 59, 26.3%), overweight (n = 88, 39.3%) and obese (n = 71, 31.7%), and each group was divided into BIVA groups (cachectic 51.8% and non-cachectic 48.2%). Results A total of 224 RA patients were included, with mean age 52.7 years and median disease duration of 12 years. Significant differences were found in weight, arm circumference, waist, hip, resistance/height, reactance/height and erythrocyte sedimentation rate among all BMI groups. However, serum albumin levels were significantly different between cachectic and non-cachectic patients independently of BMI. In all BMI categories, cachectic groups had lower reactance and phase angle than non-cachectic subjects. Conclusion RA patients with normal or even high BMI have a significantly lower muscle component. Evaluation of body composition with BIVA in RA patients could be an option for cachexia detection.

Resumen Introduccion y objetivos La laringectomia total (LT), mas eventual radioterapia, ha demostrado ser un tratamiento eficaz en los casos de cancer de hipofaringe localmente avanzado. El objetivo de este trabajo es analizar los resultados oncologicos de este procedimiento en pacientes con cancer de hipofaringe T3 y T4. Metodos Se incluyeron 59 pacientes (33 pacientes con estadio T3 y 26 con estadio T4a) con carcinoma epidermoide primario de hipofaringe tratados mediante LT entre los anos 1998 y 2012. Resultados La edad media fue de 61 anos, con predominio de varones (96,6%). Todos los pacientes excepto uno eran fumadores y el 96% consumia alcohol. Se realizo vaciamiento cervical funcional unilateral en 12 pacientes, radical unilateral en 11 pacientes, funcional bilateral en 20 pacientes y funcional mas radical en 14. El 66% de los pacientes recibieron radioterapia postoperatoria. Un 81% de los pacientes presentaba metastasis ganglionares y de estos un 56% presentaba invasion extracapsular. Un 29% de los pacientes presentaron recidiva locorregional, un 17% desarrollaron metastasis a distancia y un 25% un segundo tumor primario. La supervivencia especifica fue del 46% a los 5 anos. Conclusiones La LT ampliada a faringe (con eventual radioterapia complementaria) ofrece buenos resultados oncologicos en terminos de control locorregional de la enfermedad y supervivencia en el cancer de hipofaringe localmente avanzado, de modo que los protocolos de preservacion de organo deben alcanzar resultados oncologicos similares a los demostrados por la LT.

Introduction and objectives Total laryngectomy (TL), with eventual postoperative radiotherapy, has proven to be effective in treating cases of locally advanced hypopharyngeal cancer. The aim of this study was to analyse the oncological outcomes of this procedure in patients with hypopharyngeal cancer classified T3 and T4. Methods We studied 59 patients (33 T3 and 26 T4a) with primary squamous cell carcinoma of the hypopharynx treated with TL from 1998 to 2012. Results Mean age was 61 years with a male predominance (96.6%). All the patients were smokers and 96% consumed alcohol. Unilateral selective neck dissection (ND) was performed in 12 patients, unilateral radical ND in 11 patients, bilateral selective ND in 20 patients and radical ND plus selective ND in 14 patients. Sixty-six percentage of the patients received postoperative radiotherapy. Lymph node metastases occurred in 81% of the patients and extranodal invasion in 56% of them. Twenty-nine percentage of the patients had loco-regional recurrence, 17% developed distant metastases, and 25% a second primary tumour. The 5-year disease-specific survival was 46%. Conclusions TL extended to pharynx (with eventual postoperative radiotherapy) offers good oncological results in terms of loco-regional control and survival in locally advanced hypopharyngeal cancer, so organ preservation protocols should achieve similar oncological results to those shown by TL.

First bite syndrome is a potential complication of surgery involving the infratemporal fossa, deep lobe of the parotid gland and parapharyngeal space. It is described as an acute and intense pain in the parotid region caused with the first bite of each meal. It is related to damage to sympathetic innervation of the parotid gland. Parasympathetic hyperactivation is believed to stimulate an exaggerated myoepithelial cell contraction causing pain. Usual analgesic treatments have poor results. Botulinum toxin type A causes parasympathetic nerve paralysis of the parotid gland and this fact would minimize salivation and decrease first bite syndrome. The aim of this study is to show the details of the technique and our outcomes in 5 patients treated with botulinum toxin type A.

Introduction Over the past several decades, many acoustic parameters have been studied as sensitive to and to measure dysphonia. However, current acoustic measures might not be sensitive measures of perceived voice quality. A meta-analysis which evaluated the relationship between perceived overall voice quality and several acoustic-phonetic correlates, identified measures that do not rely on the extraction of the fundamental period, such the measures derived from the cepstrum, and that can be used in sustained vowel as well as continuous speech samples. A specific and recently developed method to quantify the severity of overall dysphonia is the acoustic voice quality index (AVQI) that is a multivariate construct that combines multiple acoustic markers to yield a single number that correlates reasonably with overall vocal quality. Methods This research is based on one pool of voice recordings collected in two sets of subjects: 60 vocally normal and 58 voice disordered participants. A sustained vowel and a sample of connected speech were recorded and analyzed to obtain the six parameters included in the AVQI using the program Praat. Statistical analysis was completed using SPSS for Windows, version 12.0. Results Correlation between perception of overall voice quality and AVQI: A significant difference exists ( t (95)=9.5; P Conclusions The findings of this study demonstrate the clinical feasibility of the AVQI as a measure of dysphonia severity.

Resumen Introduccion En las ultimas decadas se han estudiado muchos parametros acusticos con el fin de cuantificar la disfonia, sin embargo las medidas actuales podrian no ser sensibles a la calidad vocal percibida. En un metaanalisis donde se evaluo la relacion entre la calidad global percibida de la voz se identificaron numerosas medidas acusticas que no dependen de la extraccion del periodo fundamental tales como las derivadas del cepstrum y que pueden ser usadas tanto en vocales sostenidas como en habla conectada. Un metodo especifico recientemente disenado para cuantificar la severidad global de la disfonia es el indice acustico de calidad vocal (AVQI) que es un constructo multivariante que combina multiples marcadores acusticos para generar un unico numero que se correlaciona razonablemente con la calidad global vocal. Metodos Esta investigacion se baso en un archivo de voces grabadas procedentes de dos grupos de individuos: 60 personas sanas vocalmente y 58 participantes con trastornos vocales. Se grabaron vocales sostenidas y una muestral de habla conectada para su analisis y asi obtener los seis parametros incluidos en el AVQI utilizando el programa Praat. El analisis estadistico de los resultados se llevo a cabo con el programa SPSS para Windows version 12.0. Resultados Correspondencia entre el valor del AVQI y el grado de severidad global de la disfonia: correlacion r = 0,68 (p Conclusiones Los resultados obtenidos muestran una buena correlacion con la calidad vocal percibida. En conclusion, el AVQI es una medida multivariante, accesible, factible y razonablemente valida para medir clinicamente la severidad global de la severidad de la disfonia.

Introduction and objectives The aim of this study is to present our experience with the diagnostic and therapeutic approaches for parapharyngeal space tumours. Patients and method This study is a retrospective review of 90 patients diagnosed with tumours of the parapharyngeal space and treated surgically between 1984 and 2015. Patients whose tumours were not primary but invaded the parapharyngeal space expanding from another region, tumours originating in the deep lobe of the parotid gland and head and neck metastasis were excluded from this study. Results 74% percent of the parapharyngeal space neoplasms were benign and 26% were malignant. Pleomorphic adenoma was the most common neoplasm (27%), followed by paragangliomas (25%), miscellaneous malignant tumours (16%), neurogenic tumours (12%), miscellaneous benign tumours (10%), and malignant salivary gland tumours (10%). The transcervical approach was used in 56 cases, cervical-transparotid approach in 15 cases, type A infratemporal fossa approach in 13 cases, transmandibular approach in 4 cases and transoral approach in 2 cases. The most common complications were those deriving from nervous injuries. Conclusions Most parapharyngeal space tumours can be removed surgically with a low rate of complications and recurrence. The transcervical approach is the most frequently used.

Resumen Introduccion Las translocaciones de la region cromosomica 2p23 causan la sobreexpresion del gen de la quinasa del linfoma anaplasico ( ALK ), un receptor tirosinquinasa involucrado en rutas de senalizacion celular que regulan la proliferacion. Dicha alteracion se identifica en el 5% de los adenocarcinomas de pulmon, representando una diana terapeutica en dicho subgrupo de tumores. Debido a que los adenocarcinomas nasosinusales (ACNS) tienen una histologia similar a los adenocarcinomas de pulmon, el objetivo de este estudio fue evaluar si existen alteraciones en el gen ALK en los ACNS. Metodo La presencia de translocaciones del gen ALK se analizo en 96 muestras de ACNS mediante fluorescence in situ hybridization usando unas sondas «break apart». Ademas se estudio la expresion proteica de ALK por inmunohistoquimica. Resultados En ninguno de los casos se observo la presencia de translocaciones de ALK . Ademas, no se detecto expresion proteica en ninguno de los casos. Conclusiones Los resultados obtenidos sugieren que ALK no desempena un papel relevante en la oncogenesis de los ACNS.

Introduction and objectives Conventional audiometry is the gold standard for quantifying and describing hearing loss. Alternative methods become necessary to assess subjects who are too young to respond reliably. Auditory evoked potentials constitute the most widely used method for determining hearing thresholds objectively; however, this stimulus is not frequency specific. The advent of the auditory steady-state response (ASSR) leads to more specific threshold determination. The current study describes and compares ASSR, auditory brainstem response (ABR) and conventional behavioural tone audiometry thresholds in a group of infants with various degrees of hearing loss. Methods A comparison was made between ASSR, ABR and behavioural hearing thresholds in 35 infants detected in the neonatal hearing screening programme. Results Mean difference scores (±SD) between ABR and high frequency ABR thresholds were 11.2 dB (±13) and 10.2 dB (±11). Pearson correlations between the ASSR and audiometry thresholds were 0.80 and 0.91 (500 Hz); 0.84 and 0.82 (1000 Hz); 0.85 and 0.84 (2000 Hz); and 0.83 and 0.82 (4000 Hz). Conclusion The ASSR technique is a valuable extension of the clinical test battery for hearing-impaired children.

Resumen Introduccion y objetivos La audiometria convencional es el patron de referencia para cuantificar y describir una hipoacusia. Sin embargo, se precisan metodos alternativos para los pacientes muy jovenes que no pueden responder con fiabilidad. Los potenciales evocados auditivos de tronco (PEATC) es el metodo mas extendido para determinar de forma objetiva los umbrales auditivos, sin embargo, no informan especificamente en cada frecuencia. La llegada de los potenciales evocados de estado estable (PEAEE) permite conseguir una determinacion mas especifica en frecuencias. El presente trabajo describe y compara los umbrales obtenidos mediante PEATC, PEAEE y audiometria convencional en un grupo de ninos que presentan varios grados de perdida auditiva. Metodos Se llevo a cabo una comparacion entre los umbrales de PEATC, PEAEE y audiometricos obtenidos de 35 ninos detectados en el programa de cribado auditivo neonatal. Resultados La diferencia media (±DE) entre los umbrales de los PEATC y la banda de 4.000 Hz de los PEAEE fueron 11,2 dB (±13) para el oido derecho y 10,2 dB (±11) para el izquierdo. Las correlaciones de Pearson entre los umbrales de los PEAEE y audiometricos fue 0,80 y 0,91 (500 Hz); 0,84 y 0,82 (1.000 Hz); 0,85 y 0,84 (2.000 Hz); 0,83 y 0,82 (4.000 Hz), respectivamente para oido derecho e izquierdo. Conclusion La tecnica de los PEAEE es una tecnica a tener en cuenta para su inclusion en la bateria de test que se emplea en el diagnostico audiologico de los ninos con hipoacusia.

Varicella infection is one of the most common and contagious infection in children and could course with severe complications. We report the case of a 4-year-old patient derived to our hospital for suspicion of suppurative complication in the context of a varicella infection. A computerized tomographic scanning was performed, showing a large retropharyngeal abscess with mediastinitis. Complications of varicella are up to 2% of patients, but this is the first report of a retropharyngeal and mediastinal abscess in this context. In the face of clinical suspicion, early intervention is important through imaging, intravenous antibiotics and surgical drainage in necessary cases.

Objective To determine the effectiveness and outcomes of SND in the treatment of patients with squamous cell carcinoma of the head and neck (SCCHN) with clinically positive neck (cN+) at diagnosis. Material and methods We retrospectively reviewed 159 patients with SCCHN with cN+ at diagnosis, who underwent a SND with curative intent at a tertiary care academic teaching hospital in Spain. We registered patient and tumor characteristics, date and site of recurrences, together with the outcomes. Survival rates were calculated by the Kaplan-Meier method. The minimum follow-up was 18 months or till death. Results A total of 28 neck recurrences were found in the whole series but only 10 neck recurrences occurred in absence of local recurrence. The regional control in the neck in absence of local recurrence was observed in 94% of patients. The neck recurrence rates did not correlated with the pN classification (P = 0.49), the administration of postoperative radiotherapy (P = 0.49) or extranodal extension (P = 0.43). The 5-year regional recurrence-free survival rate was 80% and 92% if only isolated neck recurrences are considered. Conclusions SND offers an effective and oncologically safe surgical procedure in selected patients with clinically positive metastatic nodes in the neck. Our findings suggest that in cN1 and cN2 tumors, SND could replace the modified radical neck dissection without compromising oncologic efficacy.

Total laryngectomy (TL) and postoperative radiotherapy (RT), when indicated, have proven to be effective in treating cases of locally advanced laryngeal cancer. The aim of this study was to analyse the oncological outcomes of this procedure in patients with laryngeal cancer classified T3 and T4a.We studied 80 patients (51 T3 and 29 T4a) with primary squamous cell carcinoma of the larynx who underwent TL between 1998 and 2006. Bilateral neck dissection was performed in 54 patients, unilateral in 11, and central in 4. Twenty patients (25%) received postoperative radiotherapy.Mean age was 64 years with a male predominance (97%). As for habits, 96% were smokers and 89% consumed alcohol. Lymph node metastases occurred in 44% of patients and extracapsular invasion in 37% of them. All cases had tumour-free margins. In all, 25% of patients had loco-regional recurrence and 5% developed distant metastases. The 5-year disease-specific survival was 72% and 5-year overall survival was 55%. Variables associated with decreased disease-specific survival were T4 classification (P=.068), N2-N3 classifications (P=.005), extracapsular invasion (P=.018) and stage iv disease (P=.009). On multivariate analysis, the only variable associated with decreased disease-specific survival was the presence of N2-N3 nodal metastases (P=.008).TL is an effective treatment for the management of patients with locally advanced laryngeal cancer. Organ preservation protocols should achieve similar oncological results to those obtained with TL.

El objetivo de este trabajo es analizar los resultados oncologicos de este procedimiento en pacientes con cancer de laringe T3 y T4a. Metodos Se incluyeron 80 pacientes (51 T3 y 29 T4a) con carcinoma epidermoide primario de laringe tratados mediante LT entre los anos 1998 y 2006. Se realizo vaciamiento cervical bilateral en 54 pacientes, unilateral en 11 y central en 4. Veinte pacientes (25%) recibieron RT postoperatoria. Resultados La edad media fue de 64 anos, con predominio de varones (97%). El 96% eran fumadores y el 89% consumia alcohol. Un 44% de los pacientes presentaba metastasis ganglionares, y de estos un 37% mostro invasion extracapsular. En todos los casos se obtuvieron bordes libres de tumor. Un 25% de los pacientes presentaron recidiva locorregional y 5% desarrollaron metastasis a distancia. La supervivencia especifica a 5 anos fue de un 72% y la global del 55%. Las variables asociadas a menor supervivencia especifica fueron la clasificacion T4 (p = 0,068), la clasificacion N2-N3 (p = 0,005), la invasion extracapsular (p = 0,018) y el estadio iv (p = 0,009). En el analisis multivariante la unica variable significativa para la supervivencia especifica fue la clasificacion N2-N3 (p = 0,008). Conclusiones La LT es un tratamiento eficaz para el manejo de los pacientes con cancer de laringe localmente avanzado. Los protocolos de preservacion de organo deberian alcanzar resultados oncologicos similares a los demostrados por la LT.

Introduction and objectives: The aim of our study was to evaluate outcomes of a minimally invasive approach, using transoral surgery (TOS) as the primary treatment for oropharyngeal carcinoma. Methods: We reviewed 43 previously untreated patients with oropharyngeal carcinoma, who were treated with TOS. Distribution of the primary tumor site was: tonsil (52%), soft palate (23%), base of the tongue (21%) and posterior wall (4%). Eight patients had a stage I disease, 9 had a stage II disease, 7 had a stage III disease, 16 had a stage IVA, and 3 had stage IVB disease. Eighteen patients underwent postoperative radiotherapy. Records of these patients were reviewed to obtain measures such as local and regional control, overall and diseasespecific survival, and speech and swallowing function. Results: The overall recurrence rate was 44%, and the local recurrence rate was 18%. The 5-year overall survival and disease-specific survival rates were 55% and 66%, respectively. Five-year disease-specific survival rates by site were as follows: 100%, 85%, 44%, and 30% for posterior wall, tonsil, soft palate and base of the tongue, respectively. Five-year estimates for local control were 100%, 90%, and 0% for palate, tonsil and for base of the tongue tumors, respectively. All of the patients preserved the larynx and life without tracheotomy and oral alimentation was successful without feeding tube. Conclusion: TOS as the primary treatment approach offers a surgical alternative for treatment of the primary oropharyngeal tumor, in the era of chemoradiation therapy. This approach confers a good local control and functional outcomes.

The fundamental task of the immune system is to protect the individual from infectious organisms without serious injury to self. The essence of acquired immunity is molecular self/non self discrimination. Chronic lymphocytic leukemia is characterized by a global failure of immune system that begins with the failure of immunological tolerance mechanisms (autoimmunity) and finish with the incapacity to response to non-self antigens (immunodeficiency). Immunological tolerance mechanisms are involved in chronic lymphocytic leukemia (CLL) development. During B cell development some self-reactive B cells acquire a special BCR that recognize their own BCR. This self-autoantibody-self BCR interaction promotes survival, differentiation and proliferation of self-reactive B cells. Continuous self-autoantibody-self BCR interaction cross-linking induces an increased rate of surface BCR elimination, CD5+ expression, receptor editing and anergy. Unfortunately, some times this mechanisms increase genomic instability and promote additional genetic damage that immortalize self-reactive B cells and convert them into CLL like clones with the capability of clonal evolution and transformed CLL B cells. This review summarizes the immunological effects of continuous self-autoantibody-self BCR interaction cross-linking in the surface of self-reactive B cells and their role in CLL development.

Several studies have shown that conformational changes of β(2)-glycoprotein I (β(2)GPI) when bound to negatively charged components expose cryptic epitopes and subsequent binding of anti-β(2)GPI from patients with antiphospholipid syndrome (APS). However, the role of the carbohydrate chains of β(2)GPI in this anti-β(2)GPI reactivity is poorly understood. We therefore studied the reactivity and inhibition of anti-β(2)GPI antibodies from APS patients with native, partially glycosylated β(2)GPI (pdβ(2)GPI; without sialic acid) and completely deglycosylated β(2)GPI (cdβ(2)GPI). To determine the potential biologic importance of these glycoforms and their interaction with anti-β(2)GPI in vitro, stimulation assays were performed with the U937 cell line. Circular dichroism (CD) and fluorescence analysis of the three β(2)GPI forms were also studied. We found an increased reactivity of anti-β(2)GPI against pdβ(2)GPI and cdβ(2)GPI compared to native β(2)GPI. Both deglycosylated β(2)GPI isoforms showed higher inhibition of the anti-β(2)GPI reactivity than the native protein in soluble-phase. Likewise, the antibody/β(2)GPI/glycoform complexes increased the synthesis of IL-6, IFNγ and TNFα and the expression of HLA-DR, CD14 and CD11c in U937 cells. CD and fluorescence studies of the glycoforms yielded considerable changes in the fluorescence signals. Our work suggests that the partial or complete removal of the carbohydrate chains uncover cryptic epitopes present in β(2)GPI. The differentiation and increased synthesis of pro-inflammatory cytokines by U937 cells in vitro may have pathogenetic implications.

Regulatory Foxp3-expressing T cells (Tregs), IL-10-producing B cells (Bregs), and IDO-expressing dendritic cells (DCregs) downregulate inflammatory processes and induce peripheral tolerance, while Th17A and Th22 cell subpopulations are of proinflammatory nature. The aims of the study were to characterize and to enumerate peripheral Tregs, Bregs, and DCregs and Th17A and Th22 cell subpopulations in kidney transplant recipients (KTRs) under belatacept or cyclosporine treatment.Forty-one KRT patients (30 under belatacept treatment and 11 under cyclosporine treatment) and 26 healthy donors (HDs) were included in the study. CD19(+)-expressing peripheral B lymphocytes were purified by positive selection. IL-10-producing B cells, CD4(+)/CD25(high)Foxp3(+), and CD8(+)/CD28(-)Foxp3(+) Tregs, CCR6(+)/CD123(+)/IDO(+) DCs, as well as Th17A and Th22 cell subpopulations were quantitated by flow cytometry.Of the IL-10-producing Bregs, CD19(+)/CD24(high)/CD38(high)/CD5(+), CD19(+)/CD24(high)/CD38(high)/CD10(+), CD19(+)/CD24(high)/CD38(high)/CD20(+), and CD19(+)/CD24(high)/CD38(high)/CD27(-) had significant higher frequency in patients under belatacept treatment when compared with those under cyclosporine. Only CD19(+)/CD24(high)/CD38(high)/CD27(+) and CD19(+)/CD24(high)/CD38(high)/CXCR7(+) cells had significant higher frequency in patients under cycloporine treatment when compared to those under belatacept. The percentages of IDO-expressing pDC, CD4(+)/CD25(high)Foxp3(+), and CD8(+)/CD28(-)Foxp3(+) were significantly higher in the belatacept group when compared the cyclosporine one, while Th17A and Th22 cells had significant higher frequency in the latter group.Belatacept seems to maintain and enhance, at least systemically, a tolerant profile to renal allograft in transplant recipients by means of higher circulatory frequencies of regulatory B, T and pDC subpopulations.

Sinonasal carcinomas are rare tumours with an unfavourable prognosis whose management is difficult and complex, leading to high morbidity and mortality despite improvements in the field of surgery and radiotherapy. An elevated number of these tumours can be attributed to occupational exposure. In comparison with other head and neck malignancies, studies of molecular changes in these tumours are infrequent. This review was focused on findings about the epidemiology and molecular and phenotypic characterisation of sinonasal carcinomas, which can potentially be useful for diagnosis and treatment. The increasing knowledge about the molecular biology that underlies their carcinogenesis may help to identify precursor lesions, prognostic markers and markers that predict chemoradiotherapy response and, finally, to identify potential molecular targets that will expand treatment options.

Resumen Los carcinomas nasosinusales son tumores infrecuentes, con mal pronostico, y cuyo manejo es dificil y complejo, conllevando una elevada morbimortalidad, a pesar de los tratamientos quirurgicos agresivos y la administracion de radio y quimioterapia. Son tumores frecuentemente relacionados con la exposicion profesional a carcinogenos. A diferencia de otros tumores de cabeza y cuello los estudios acerca de los cambios genetico-moleculares de estos tumores son escasos. Esta revision se centra en los hallazgos acerca de la epidemiologia y la caracterizacion molecular y fenotipica de los carcinomas nasosinusales y, sus posibles implicaciones en el diagnostico y tratamiento de los mismos. El progresivo conocimiento acerca de la biologia molecular que subyace a su oncogenesis ayudaria a identificar las lesiones precursoras, los marcadores pronosticos y de respuesta a la quimiorradioterapia e identificar potenciales dianas moleculares que permitan ampliar las opciones terapeuticas.
