Comparación de dos cuestionarios específicos de calidad de vida en población pediátrica con patología adenoamigdalar / Comparison of two specific quality of life questionnaires in a paediatric population with adenotonsillar disease

Introducción y objetivo: El T-14 y el TAHSI son cuestionarios específicos validados y fiables para medir la calidad de vida en pacientes pediátricos con patología adenoamigdalar. El presente trabajo tiene como objetivo comparar las versiones adaptadas y validadas en lengua española de estos dos cuestionarios (T-14-s y s-TAHSI) con la finalidad de valorar la adopción preferente de alguno de ellos en nuestro medio.Material y MétodosPara determinar la existencia de una correlación entre ambos instrumentos, se realizó un estudio prospectivo transversal, multicéntrico, entre noviembre de 2015 y abril de 2016. Se incluyeron consecutivamente sujetos de dos a 16 años de edad con indicación de cirugía adenoamigdalar y controles sanos. Los padres o tutores legales respondieron los cuestionarios T-14-s y s-TAHSI inicialmente, pasadas dos-seis semanas y a los seis meses de la cirugía. Se compararon las puntuaciones de T-14-s y s-TAHSI de toda la muestra globalmente, de los subgrupos de pacientes y controles por separado y, finalmente, del grupo de pacientes a los seis meses de la cirugía, mediante el coeficiente de correlación de Pearson. Se calculó la proporción de variabilidad compartida entre ambos test.ResultadosSe estudiaron 100 sujetos (50 pacientes y 50 controles). La correlación global que presentaron ambos cuestionarios fue muy alta (0,97), con un nivel de significación de p < 0,01. La proporción de variabilidad compartida fue muy elevada, del 94%. Los resultados se mantuvieron al comparar los cuestionarios en las subpoblaciones de casos y controles, así como los cuestionarios postoperatorios.ConclusiónLos cuestionarios de calidad de vida para pacientes pediátricos con patología adenoamigdalar, T-14-s y s-TAHSI, presentan una alta correlación que permite el uso equivalente de ambos en nuestro medio.

Recomendaciones de la Guía de Práctica Clínica de la exploración de la vía aérea superior para pacientes adultos con sospecha de síndrome de apnea-hipoapnea obstructiva del sueño (versión reducida) / Clinical Practice Guideline recommendations on examination of the upper airway for adults with suspected obstructive sleep apnoea-hypopnoea syndrome

En noviembre 2014 la Sociedad Española de Otorrinolaringología, la Sociedad Española de Sueño y la Sociedad Española de Cirugía Maxilofacial propusieron y avalaron la elaboración de una Guía de Práctica Clínica sobre la exploración física de la vía aérea superior en pacientes con apnea obstructiva del sueño. La Guía ha seguido de forma estricta en toda su elaboración las recomendaciones del manual de elaboración de guías de práctica clínica del Sistema Nacional de Salud 2007 y 2009 y el manual de la Scottish Intercollegiate Guidelines Network (SIGN) 2015. El documento final puede ser altamente útil para los fines que se propuso inicialmente: ser un referente para unificar las regiones que deben ser exploradas en los pacientes con síndrome de apnea-hipoapnea obstructiva del sueño, mediante qué tipo de exploración y cómo gradarla, y expresada para todos los ámbitos asistenciales a los que estos pacientes pueden acudir. Las conclusiones y recomendaciones están basadas en una revisión exhaustiva y actualizada de la bibliografía con alto nivel de evidencia, además de la experiencia y conocimientos demostrados de todos los integrantes del grupo de elaboración. Dicho grupo se constituyó pensando siempre en la transversalidad del proyecto, y, por tanto, han participado especialistas de todos los ámbitos implicados (cirugía maxilofacial, medicina de familia, neumología, neurofisiología clínica, odontología y otorrinolaringología). Con la misma idea se seleccionaron los revisores externos del texto final

In November 2014 the Spanish Society of Otolaryngology, the Spanish Sleep Society and the Spanish Society of Maxillofacial Surgery proposed and endorsed the development of a Clinical Practice Guideline on the physical examination of the upper airway in patients with obstructive sleep apnoea. The Guideline strictly followed the recommendations of the manual for the preparation of clinical practice guidelines of the National Health System 2007 and 2009 and the manual of the Scottish Intercollegiate Guidelines Network (SIGN) 2015. The final document could be highly useful for the purposes that were originally proposed: to act as a reference to unify the regions that should be explored in patients with obstructive sleep apnoea-hypopnoea syndrome, the type of examination and how to grade it, and specific to all the care areas to which these patients have access. The conclusions and recommendations are based on a thorough and up-to-date review of the literature with a high level of evidence, as well as the experience and knowledge demonstrated by all the members of the drafting group. This group was formed bearing in mind at all times the transversality of the project, and, therefore, specialists from all the involved areas participated (maxillofacial surgery, family medicine, pneumology, clinical neurophysiology, odontology and otolaryngology).

A case-control study of Drug-Induced Sleep Endoscopy (DISE) in pediatric population: A proposal for indications.

OBJECTIVE: To evaluate whether and when Drug-Induced Sleep Endoscopy (DISE) changes diagnosis and treatment plan in pediatric Obstructive Sleep Apnoea Syndrome (OSAS) with the aim to identify specific subgroups of patients for whom DISE should be especially considered. METHODS: A case-control study of DISE in 150 children with OSAS. Pre-operative OSA were assessed through detailed history, Chervin questionnaire, physical examination and overnight polysomnography. The group of study was divided into three subgroups according to clinical and polysomnographyc criteria: conventional OSAS, disproportional OSAS and persistent OSAS. Endoscopic evaluation of the upper airway during DISE was scored using Chan classification. Surgical treatment was tailored individually upon the basis of sleep endoscopy findings: performance of any surgery other than tonsillectomy and adenoidectomy (T&A) was considered as a change of the treatment plan. Cases and controls were compared considering presence and absence of DISE-directed extra surgery, respectively. RESULTS: 150 patients with mean age (SD) 56.09 (23.94) months and mean apnoea-hypopnea index (AHI) of 5.79 (6.52) underwent DISE. The conventional subgroup represented the 58.67% of the sample (n = 88), while the disproportional one counted for the 26.67% (n = 40), and the persistent one for 14.66% (n = 22) of the population. Sleep endoscopy changed the surgical plan in 4.5% of conventional OSAS, 17.5% of disproportional OSAS and 72.7% of persistent OSAS (p < 0.005). Overall, a change of the treatment plan operated by DISE was associated with a non-conventional OSAS status (OR = 6; 95% CI = 1.6-26.4). CONCLUSIONS: DISE is a safe procedure in children suffering from OSAS, and, despite being unnecessary in conventional cases of OSA, DISE should be considered not only in syndromic children, as previously demonstrated, but also in the general non-syndromic pediatric population, in the case of non-conventional OSA patients, and in children with persistent OSAS.

Adaptation and validation of the Spanish version of the Tonsil and Adenoid Health Status Instrument.

OBJECTIVES/HYPOTHESIS: The Tonsil and Adenoid Health Status Instrument (TAHSI) is a disease-specific questionnaire, intended for completion by parents, for assessing quality of life related to tonsil and adenoid disease or its treatment in children with throat disorders. The aim of this study was to validate the Spanish adaptation of the TAHSI, thus allowing comparison across studies and international multicenter projects. STUDY DESIGN: Multicenter prospective instrument validation study. METHODS: Guidelines for the cross-cultural adaptation process from the original English-language scale into a Spanish-language version were followed. The psychometric properties (reproducibility, reliability, validity, responsiveness) of the Spanish version of the TAHSI (s-TAHSI) were assessed in 51 consecutive children undergoing adeno/tonsillectomy (both before and 6 months after surgery) and a separate cohort of 50 unaffected children of comparable age range. RESULTS: Test-retest reliability (γ = 0.8) and internal consistency reliability (α = 0.95) were adequate. The s-TAHSI demonstrated satisfactory content validity (r > 0.40). The instrument showed excellent between-groups discrimination (P < .0001) and high responsiveness to change (effect size = 2.09). CONCLUSIONS: Psychometric testing of the s-TAHSI yielded satisfactory results, thus allowing assessment of the subjective severity of throat disorders in children. LEVEL OF EVIDENCE: 2c.

Tratamiento quirúrgico del síndrome de apnea obstructiva del sueño infantil: comparación entre adenoamigdalectomía extracapsular con bisturí frío y reducción mediante radiofrecuencia bipolar / Surgical treatment for childhood obstructive sleep apnoea: Cold-knife tonsillar dissection versus bipolar radiofrequency thermal ablation

Introducción y objetivos: La cirugía adenoamigdalar para el tratamiento de los niños con apnea obstructiva del sueño es efectiva. La incomodidad y posibles complicaciones del postoperatorio han promovido la utilización de técnicas parciales que buscan mejorar estos aspectos sin renunciar a resolver el síndrome con la misma efectividad. El objetivo es presentar la experiencia de 2 grupos consecutivos de pacientes, uno tratado con cirugía amigdalar total extracapsular y otro con reducción con radiofrecuencia bipolar mediante tunelización. Metodo: Se comparan 96 niños tratados mediante adenoamigdalectomía total extracapsular con bisturí frío y 101 tratados mediante radiofrecuencia. Se evalúa el porcentaje de casos con persistencia del síndrome (índice de apnea-hipoapnea ≥3) y la mejoría de los síntomas clínicos a un año. Se compara también el porcentaje de complicaciones quirúrgicas y anestésicas en ambos grupos. Resultado: La persistencia del síndrome fue comparable estadísticamente en ambos grupos: 25% en el grupo de bisturí frío y 22,77% en el grupo de radiofrecuencia. Las complicaciones anestésicas (5% en el grupo de bisturí frío y 4,2% en el grupo de radiofrecuencia) y los porcentajes de hemorragia postoperatoria fueron muy bajos y estadísticamente comparables con ambas técnicas. Conclusión: En el tratamiento del síndrome de apnea obstructiva del sueño infantil, tanto la cirugía extracapsular con bisturí frío como la radiofrecuencia bipolar mediante tunelización son técnicas seguras y los resultados en la resolución del síndrome no muestran diferencias estadísticamente significativas (AU)

Introduction and objective: Adenotonsillectomy for treatment of childhood obstructive sleep apnoea is effective. The uncomfortable postoperative period and possible complications have significantly increased the use of partial techniques, seeking to improve these aspects while achieving the same results in resolving sleep apnoea. The aim was to present the experience with 2 consecutive groups of patients, comparing total tonsillectomy to bipolar radiofrequency ablation (RFA). Method: A group of 96 children that underwent total tonsilloadenoidectomy using cold dissection were compared to another group of 101 children that underwent RFA. In all cases, polysomnography was performed before and 1 year after surgery. The percentage of cases with persistent disease (apnea-hypopnea index ≥ 3) and the improvement of clinical symptoms at one year were evaluated. The percentages of surgical and anaesthetic complications in both groups were also compared. Result: The persistence of the syndrome was comparable in both groups: 25% in the cold dissection and 22.77% in the radiofrequency ablation group. Anaesthetic complications (5% in the group where cold dissection was used and 4.2% in the radiofrequency ablation group) and postoperative bleeding rates were very low and statistically comparable with both techniques. Conclusion: In the treatment of childhood obstructive sleep apnoea syndrome, both extracapsular surgery using cold scalpel and bipolar radiofrequency tunnelling techniques are safe. Likewise, results as to resolution of the syndrome show no statistically significant differences (AU)

Exploración videosomnoscópica bajo sueño inducido en los trastornos respiratorios del sueño en niños / Drug-induced sleep-endoscopy in children's sleep related breathing disorders

Introducción y objetivos: La somnoscopia es una herramienta válida para evaluar los lugares de obstrucción de la vía aérea superior responsables del síndrome de apnea-hipoapnea del sueño infantil. El objetivo es mostrar la experiencia de un servicio de ORL con somnoscopia en niños candidatos a cirugía de síndrome de apnea del sueño. Métodos: Incluye 56 casos entre 2 y 12 años de edad que acuden a la consulta de otorrinolaringología con clínica de ronquido y apnea. Se practica polisomnografía previa y el IAH medio fue 6,32±8,71. La distribución de casos fue: 10 residuales (17,85%), 15 desproporción clínica (26,78%) y 31 convencionales (55,35%). Todas las exploraciones se llevan a cabo en quirófano y se utiliza la clasificación de Chan para valorar las zonas de colapso. Resultados: En los casos de enfermedad residual las regiones más afectadas son las paredes laterales de la orofaringe (70%) y los cornetes (70%), y la cirugía aplicada con más frecuencia la amigdalectomía total seguida de la reducción de la base de la lengua y la radiofrecuencia de los cornetes. En los casos de desproporción clínica se halló mayor frecuencia de colapso en las paredes laterales de la orofaringe (93,3%) y adenoides (66,6%). La cirugía más frecuente en este grupo fue la adenoidectomía con amigdalotomía por radiofrecuencia. Conclusión: La somnoscopia es una técnica de exploración que puede ser incorporada con facilidad a la práctica habitual, especialmente en niños con síndrome de apnea del sueño residual o en aquellos en los que se sospeche alguna otra causa aparte de la hipertrofia adenoamigdalar (AU)

Introduction: Drug-induced sedation endoscopy is a valid tool to assess site obstruction of the upper airway responsible for children's obstructive Sleep Apnea. The aim is to show the experience of an ENT department with Drug-induced sedation endoscopy in children selected for sleep apnea surgery. Methods: Includes 56 cases between 2 and 12 years old (mean age: 59,13±27,29 months) presenting at the Otorhinolaryngology consultation clinic with snoring and apnea. Prior polysomnography had been practiced and mean AHI was 6,32±8,71. The distribution of cases was 10 persistent sleep apnea (17.85%), 15 clinical disproportion (26.78%) and 31 conventional (55.35%). All sleep endoscopies were performed in the operating room and Chan classification was used to assess the areas of collapse. Results: In cases of residual disease the most affected regions were the side walls of the oropharynx (70%) and turbinate (70%) and the most frequently applied surgery was total tonsillectomy followed by second tongue tonsil reduction and turbinate radiofrequency. In clinical cases of desproportion, the most affected regions were the oropharyngeal side walls (93.3%) and adenoids (66.6%). The most frequently applied surgery in this group was adenoidectomy and radiofrequency tonsillotomy. Conclusion: drug-induced sedation endoscopy is a technique that can be incorporated easily into medical practice, mostly in children with residual sleep apnea syndrome or those suspected to have some cause other than adenotonsillar hypertrophy (AU)

Management of recurrent head and neck cancer: variables related to salvage surgery.

After a local and/or regional recurrence of head and neck squamous cell carcinoma (HNSCC) not all patients are candidates to salvage treatment. The objective of this study was to identify the variables related to performance of salvage surgery with curative intent in these patients. We performed a retrospective study of 1088 HNSCC patients with a local and/or regional recurrence. According to a multivariate analysis, the variables related to performance of salvage surgery were the Karnofsky index, the location and extension of the primary tumor, the initial treatment, the disease-free interval between treatment of the initial tumor and diagnosis of the recurrence, and the year the recurrence was diagnosed. Considering salvage surgery as the dependent variable, the results of a recursive partitioning analysis defined four categories of patients in function of the category of local and regional extension of the initial tumor, the location of the primary tumor, the initial treatment and the disease-free interval between treatment of the initial tumor and diagnosis of the recurrence.

Síndrome de la apnea-hipoapnea obstructiva del sueño en el niño: más allá de la hipertrofia adenoamigdalar / Obstructive sleep apnea-hypopnea syndrome in children: Beyond adenotonsillar hypertrophy

La prevalencia del síndrome de la apnea-hipoapnea obstructiva del sueño en la población infantil general es del 1-2% y su causa más frecuente es la hipertrofia adenoamigdalar. Las prevalencias en las otras causas de este síndrome, más allá de la hipertrofia adenoamigdalar, son elevadas. En muchas de estas enfermedades los motivos por los que se genera el síndrome de la apnea-hipoapnea obstructiva del sueño son multifactoriales (hipotonía muscular, alteraciones dentofaciales, hipertrofia de tejidos blandos de la vía aérea, alteraciones neurológicas). Es fundamental la colaboración entre las diferentes especialidades implicadas, dada la gran variabilidad de enfermedades, la frecuente participación de diferentes factores en su génesis y los diferentes tratamientos que deben aplicarse. Se ha procedido a una amplia revisión bibliográfica de estas otras causas de síndrome de la apnea-hipoapnea obstructiva del sueño infantil, que van más allá de la hipertrofia adenoamigdalar. Se han intentado ordenar de una forma coherente, a criterio del autor, revisando los aspectos más destacados con relación a la prevalencia de síndrome de la apnea-hipoapnea obstructiva del sueño en cada una de ellas, los motivos por los que provocan este síndrome, sus interacciones y manejo (AU)

The prevalence of obstructive sleep apnea-hypopnea syndrome in the general childhood population is 1-2% and the most common cause is adenotonsillar hypertrophy. However, beyond adenotonsillar hypertrophy, there are other highly prevalent causes of this syndrome in children. The causes are often multifactorial and include muscular hypotonia, dentofacial abnormalities, soft tissue hypertrophy of the airway, and neurological disorders). Collaboration between different specialties involved in the care of these children is essential, given the wide variability of conditions and how frequently different factors are involved in their genesis, as well as the different treatments to be applied. We carried out a wide literature review of other causes of obstructive sleep apnea-hypopnea syndrome in children, beyond adenotonsillar hypertrophy. We organised the prevalence of this syndrome in each pathology and the reasons that cause it, as well as their interactions and management, in a consistent manner (AU)

Stomal recurrence in head and neck cancer patients with temporary tracheostomy.

OBJECTIVE: Stomal recurrence following a temporary tracheostomy in the management of the head and neck squamous cell carcinoma (HNSCC) without laryngectomy is a rare finding. We studied the incidence and prognostic significance of stomal recurrence in patients who had a temporary tracheostomy. METHODS: Data were obtained retrospectively from a database on all patients with a HNSCC tumour diagnosed and treated at our hospital between 1985 and 2012. RESULTS: Of 491 patients who underwent temporary tracheostomy, six presented tumour recurrence in the stomal scar. The risk of stomal recurrence after a temporary tracheostomy was therefore 1.2% (6/491). Only one of the three patients who received salvage treatment achieved disease control. CONCLUSION: Tumour recurrence in the stomal scar after a transitory tracheostomy in patients with head and neck carcinoma has an incidence of around 1% and very poor prognosis.

Inclusion of extracapsular spread in the pTNM classification system: a proposal for patients with head and neck carcinoma.

IMPORTANCE: The inclusion of data about the presence of metastatic neck nodes with extracapsular spread (ECS) in the neck dissection improves the prognostic classification of patients with head and neck squamous cell carcinoma (HNSCC). OBJECTIVE: To evaluate the prognostic capacity of ECS in patients with HNSCC, and to analyze the usefulness of including this information in the pathological classification of patients treated with a neck dissection. DESIGN: Retrospective unicenter study performed from 1985 through 2007. SETTING: Tertiary referral center. PARTICIPANTS: A total of 1190 patients with HNSCC treated with a neck dissection. INTERVENTION: Unilateral or bilateral neck dissection . MAIN OUTCOMES AND MEASURES: Adjusted survival and local, regional, and distant metastases-free survival. Patients were classified according to a recursive partitioning analysis (RPA) method, considering pN category and number of neck nodes with ECS as the independent variables. RESULTS: Five-year adjusted survival for patients without metastatic nodes in the neck dissection (pN0) was 85.5%, for patients with neck node metastases without ECS (pN+/ECS-) it was 62.5%, and for patients with neck node metastases with ECS (pN+/ECS+) it was 29.9%. There were significant differences in survival between patients with pN0 lesions and pN+/ECS- (P < .001), and between patients with pN+/ECS- and those with pN+/ECS+ (P < .001). According to the RPA method, we propose classifying patients according to 4 categories: category I, pN0 lesions; category II, pN1/ECS+ or pN+/ECS-; category III, pN2-3/1 node and ECS+; and category IV, pN2-3/2 or more nodes and ECS+. The RPA-derived classification achieved a better prognostic discrimination than the pTNM classification. CONCLUSIONS AND RELEVANCE: The inclusion of information about ECS in the neck dissection improved the prognostic classification of patients with HNSCC in relation to the pTNM classification.

Correlación entre la clínica y la polisomnografía en los trastornos respiratorios del sueño infantil / Clinical and polysomnographic correlation in sleep-related breathing disorders in children

Introducción: A pesar de que la polisomnografía supone la prueba diagnóstica por excelencia de los trastornos respiratorios del sueño en niños, existe controversia sobre su indicación en todos los casos. De entre los argumentos utilizados, tanto a favor como en contra, se encuentra la falta de correlación existente entre sus valores objetivos y la sintomatología. Objetivo: Evaluar la correlación entre los datos clínicos y el índice de apnea-hipoapnea (IAH), en nuestro entorno de trabajo. Material y método: Se compara estadísticamente la clínica preoperatoria y el IAH de 170 niños con trastorno respiratorio del sueño, sometidos a polisomnografia. También se evalúa la correlación a nivel postoperatorio, con un subgrupo de 80 niños intervenidos de adenoamigdalectomía con seguimiento polisomnográfico a un año. Resultados: A nivel preoperatorio únicamente el grado de hipertrofia amigdalar mostró correlación significativa con el IAH. A nivel postoperatorio se evidencia una correlación entre el IAH y las apneas observadas: 38,1% de los niños mejoran según los padres en el grupo con persistencia polisomnográfica y el 66,7% en el grupo con resolución de la enfermedad (p=0,023). También muestra correlación el nivel de mejora del ronquido, valorado mediante escala analógica visual. La media bajó 5 puntos en el grupo persistente y 6,1 en el grupo con resolución de la enfermedad (p=0,047). Conclusión: A pesar de las limitaciones en la correlación entre la clínica y la polisomnografia, especialmente en el preoperatorio, la prueba objetiva por excelencia sigue siendo esta. Deben hacerse esfuerzos para conseguir parámetros objetivos que aporten mayor nivel de correlación (AU)

Introduction: Although polysomnography is the gold standard test for sleep-disordered breathing in children, there is controversy about its indication in all cases. Among the arguments both for and against is the lack of correlation between objective values and the symptoms. Objective: To evaluate the correlation between clinical data and apnea-hypopnoea index (AHI) in our work environment. Material and methods: We compared the preoperative clinical symptoms and AHI statistically in 170 children with sleep-disordered breathing who underwent polysomnography. We also analysed the correlation to postoperative level, with a subgroup of 80 children who underwent adenotonsillectomy with 1 year of polysomnography follow-up. Results: Before surgery, only the degree of tonsillar hypertrophy was statistically significant correlated with AHI. At post-operative follow-up, evidence of correlation between AHI and apnoea was observed: 38.1% of children improved in the group with persistence and 66.7% in the disease resolution group (P=0.023). In addition, the correlations showed the level of improvement of snoring, as assessed by visual analogue scale. The mean was 5 points lower in the persistent group and 6.1 lower in the disease resolution group (P=0.047). Conclusion: Despite the limitations in the correlation between clinical data and polysomnography, especially in preoperative results, polysomnography remains the gold standard diagnostic tool.

Clinical and polysomnographic correlation in sleep-related breathing disorders in children.

INTRODUCTION: Although polysomnography is the gold standard test for sleep-disordered breathing in children, there is controversy about its indication in all cases. Among the arguments both for and against is the lack of correlation between objective values and the symptoms. OBJECTIVE: To evaluate the correlation between clinical data and apnea-hypopnoea index (AHI) in our work environment. MATERIAL AND METHODS: We compared the preoperative clinical symptoms and AHI statistically in 170 children with sleep-disordered breathing who underwent polysomnography. We also analysed the correlation to postoperative level, with a subgroup of 80 children who underwent adenotonsillectomy with 1 year of polysomnography follow-up. RESULTS: Before surgery, only the degree of tonsillar hypertrophy was statistically significant correlated with AHI. At post-operative follow-up, evidence of correlation between AHI and apnoea was observed: 38.1% of children improved in the group with persistence and 66.7% in the disease resolution group (P=.023). In addition, the correlations showed the level of improvement of snoring, as assessed by visual analogue scale. The mean was 5 points lower in the persistent group and 6.1 lower in the disease resolution group (P=.047). CONCLUSION: Despite the limitations in the correlation between clinical data and polysomnography, especially in preoperative results, polysomnography remains the gold standard diagnostic tool. Efforts should be made to obtain objective parameters that provide higher levels of correlation.

Second, third, and fourth head and neck tumors. A progressive decrease in survival.

BACKGROUND: Patients with a first head and neck carcinoma have a high risk of successive neoplasms, many of which appear again in the head and neck. Second head and neck tumors have a poorer prognosis than first tumors, but data about the prognosis of third and fourth tumors in the head and neck are lacking. METHODS: We carried out a retrospective study of 4298 patients with a primary head and neck carcinoma. Survival and the characteristics of the first tumor, second tumor, and any successive tumors in the head and neck were analyzed. RESULTS: Second and successive tumors showed a tendency to appear more frequently in the oral cavity and oropharynx and had a lower stage than that of index tumors. Five-year survival rates after a first, second, third, and fourth tumors in the head and neck were 67.6%, 56.1%, 45.0%, and 32.1%, respectively. CONCLUSION: Survival decreased progressively with every new head and neck tumor.

Proton-pump inhibitors in sleep-related breathing disorders: clinical response and predictive factors.

BACKGROUND AND AIM: Gastroesophageal reflux is frequently associated with sleep-related breathing disorders. We aimed to evaluate the prevalence of acid reflux in patients with sleep-related breathing disorders, their clinical response to proton-pump inhibitor (PPI) treatment, and to identify predictive response factors to this treatment. METHODS: Prospective study among patients attending a sleep clinic. Evaluation of typical and atypical gastroesophageal reflux symptoms, simultaneous 24 h dual-channel pH monitoring and polysomnography were performed in all patients. Patients were treated with pantoprazole. After 3-6 months clinical response was evaluated, and pHmetry and polysomnography repeated. Clinical response was defined in terms of snore, apnea and somnolence grading. Improvement in polysomnography was defined by the Stanford criteria. RESULTS: One hundred and ninety-nine patients were included. Abnormal reflux levels were detected in the distal esophagus in 72% of patients, and in the proximal esophagus in 46%. Clinical or polysomnographic response to PPI treatment was found in 78% of patients. Pretreatment pHmetry was a significant predictor of success: 67% of responders had pathological proximal pHmetry (vs. 33% of nonresponders; P<0.001), and 55% also had pathological distal pHmetry (P<0.05). Age, sex, BMI, alcohol or tobacco abuse, typical or atypical gastroesophageal reflux symptoms, severity of sleeping disorder, and polysomnography were not predictive of outcome. CONCLUSIONS: Patients with sleep-related breathing disorders have an increased prevalence of gastroesophageal reflux disease. They may be successfully treated with PPIs, particularly in patients with an abnormal proximal esophageal pHmetry.

[Undiagnosed (corrected) cases of obstructive sleep apnoea syndrome: a new reason for involvement of otorhinolaryngologists]. / Casos no diagnosticados de síndrome de apnea obstructiva del sueño: un nuevo motivo de implicación para el otorrinolaringólogo.

INTRODUCTION: In Spain there are around 2 million people with obstructive sleep apnoea syndrome who should be treated. However, less than 10 % have been diagnosed and treated. Untreated patients are associated with a higher risk of cardiovascular and neurological complications, higher accident rates, reduced quality of life and greater health-care consumption. It is necessary, therefore, to reduce these consequences through early diagnosis and treatment. OBJECTIVE: To demonstrate the usefulness of a simple series of questions and examination as a mechanism to detect patients with undiagnosed obstructive sleep apnoea syndrome, in a consultation with a general otorhinolaryngologist. MATERIAL AND METHOD: Five hundred two consecutive patients coming to an otorhinolaryngological consultation for reasons other than sleep pathology were submitted to a series of questions and an examination of upper aerodigestive tract, to search for indications of suspected sleep apnoea. For the different clinical and anatomical comparisons, a control group of 178 consecutive already-diagnosed patients was used. RESULTS: Of the 502 cases, 74 (14.7%) fulfilled the requirements for suspicion and 35 of them agreed to take a polysomnograph test (47.29%). Of this group, an apnoea/ hypopnoea index greater than 5 was found in 24 of the 35 cases (4.78%). CONCLUSIONS: The prevalence of obstructive sleep apnoea in the group of patients studied is greater than that of the general population. With a simple interview and physical examination, a high rate of success can be obtained in the detection of undiagnosed sleep apnoea cases.
