ZUSAMMENFASSUNGZiel der vorliegenden nicht interventionellen Studie war die Untersuchung der klinischen Wirksamkeit und Verträglichkeit einer Fixkombination aus Cinnarizin (20 mg) und Dimenhydrinat (40 mg) bei Patienten, die unter Schwindel und Gleichgewichtsstörungen leiden. Zu diesem Zweck wurden 120 Erwachsene (70 Männer) mit einem Durchschnittsalter von 64 Jahren in die Studie aufgenommen. Vor Beginn der pharmakologischen Behandlung wurden alle Patienten anhand der Visual Scale of Dizziness Disorders und des Dizziness Handicap Inventory auf die Intensität des Schwindels und dessen Begleitsymptome untersucht. Im Anschluss an die anamnestische Untersuchung erhielten die Patienten 60 Tage lang 3-mal täglich die Fixkombination aus Cinnarizin und Dimenhydrinat.Unabhängig von der Art des Schwindels führte die Fixdosiskombination 15 Tage nach Behandlungsbeginn bei mehr als 75 % aller Patienten zu einer Verringerung der mit Schwindel und Gleichgewichtsstörungen verbundenen Symptome – bei einer weiteren Verbesserung nach 60 Tagen. Interessanterweise fanden wir Unterschiede zwischen männlichen und weiblichen Patienten, was die pharmakologische Wirkung der Therapie betraf.

OBJECTIVES: To evaluate electrophysiological findings among patients with vestibular migraine (VM) and to compare them with those of patients suffering from definite Ménière disease (MD) without migraine. MATERIALS and METHODS: Twenty-one consecutive patients suffering from VM were enrolled; all subjects were selected according to the criteria proposed by the Bàràny Society for Neuro-otology. Each patient underwent a careful otological and neurotological examination. After completing a questionnaire regarding migraine and vertigo complaints, they were assessed by audiometric testing, video head impulse test (vHIT), and elec-trocochleography (EcochG). Data were compared with those of 21 patients who fulfilled the criteria for definite MD. RESULTS: 52.38% of the patients with VM suffered from at least two episodes of migraine per week, with 42.85% of the subjects complaining of migraines lasting ≥24 hours. 57.14% of the patients reported at least four episodes of vertigo per month, whereas 61.9% suffered from symptoms of chronic unsteadiness. No significant difference (p=0.76) resulted from the comparison of vHIT gain between patients with VM and MD. Eleven out of 21 patients (52.38%) with definite MD presented at least one ear with SP/AP >0.4, differently from patients with VM who exhibited SP/AP values suggestive of endolymphatic hydrops (EH) in only three cases (14.28%). CONCLUSION: The present study found a higher proportion of abnormal EcochG in MD than in VM (p=0.02) without any significant difference in the vHIT gain. On the basis of our findings, the identification of EH in some patients with VM cannot be definitely related to the same pathway that triggers MD symptoms. Future research may help in better understanding whether abnormal EcochG findings can predict the occurrence of MD among patients with VM.

Introduction: The treatment of laryngeal squamous cell carcinoma needs accurate risk stratification, in order to choose the most suitable therapy. The prognostic significance of resection margin is still highly debated, considering the contradictory results obtained in several studies regarding the survival rate of patients with a positive resection margin. Objective: To evaluate the prognostic role of resection margin in terms of survival and risk of recurrence of primary tumour through survival analysis. Methods: Between 2007 and 2014, 139 patients affected by laryngeal squamous cell carcinoma underwent partial or total laryngectomy and were followed for mean of 59.44 ± 28.65 months. Resection margin status and other variables such as sex, age, tumour grading, pT, pN, surgical technique adopted, and post-operative radio- and/or chemotherapy were investigated as prognostic factors. Results: 45.32% of patients underwent total laryngectomy, while the remaining subjects in the cohort underwent partial laryngectomy. Resection margins in 73.39% of samples were free of disease, while in 21 patients (15.1%) anatomo-pathological evaluation found one of the margins to be close; in 16 subjects (11.51%) an involved resection margin was found. Only 6 patients (4.31%) had a recurrence, which occurred in 83.33% of these patients within the first year of follow-up. Disease specific survival was 99.24% after 1 year, 92.4% after 3 years, and 85.91% at 5 years. The multivariate analysis of all covariates showed an increased mortality rate only with regard to pN (HR = 5.043; p = 0.015) and recurrence (HR = 11.586; p = 0.012). Resection margin did not result an independent predictor (HR = 0.757; p = 0.653). Conclusions: Our study did not recognize resection margin as an independent prognostic factor; most previously published papers lack unanimous, methodological choices, and the cohorts of patients analyzed are not easy to compare. To reach a unanimous agreement regarding the prognostic value of resection margins, it would be necessary to carry out meta-analyses on studies sharing definition of resection margin, methodology and post-operative therapeutic choices. Resumo: Introdução: O tratamento do carcinoma de células escamosas de laringe necessita de uma estratificação precisa do risco, para a escolha da terapia mais adequada. O significado prognóstico da margem de ressecção ainda é motivo de debate, considerando-se os resultados contraditórios obtidos em vários estudos sobre a taxa de sobrevida de pacientes com margem de ressecção positiva. Objetivo: Avaliar o papel prognóstico da margem de ressecção em termos de sobrevida e risco de recorrência de tumor primário através da análise de sobrevida. Método: Entre 2007 e 2014, 139 pacientes com carcinoma de células escamosas de laringe foram submetidos à laringectomia parcial ou total e foram acompanhados por um tempo médio de 59,44 ± 28,65 meses. O status de margem de ressecção e outras variáveis, como sexo, idade, grau do tumor, pT, pN, técnica cirúrgica adotada e radio- e/ou quimioterapia pós-operatória, foram investigados como fatores prognósticos. Resultados: Dos pacientes, 45,32% foram submetidos à laringectomia total, enquanto os demais foram submetidos à laringectomia parcial. As margens de ressecção em 73,39% das amostras estavam livres, enquanto em 21 pacientes (15,1%) a avaliação anatomopatológica encontrou uma das margens próxima e 16 indivíduos (11,51%) apresentaram margem de ressecção comprometida. Apenas seis pacientes (4,31%) apresentaram recidiva, o que ocorreu em 83,33% desses pacientes no primeiro ano de seguimento. A sobrevida doença-específica foi de 99,24% em um ano, 92,4% em três anos e 85,91% em cinco anos. A análise multivariada de todas as covariáveis mostrou um aumento na taxa de mortalidade apenas em relação à pN (HR = 5,043; p = 0,015) e recidiva (HR = 11,586; p = 0,012). A margem de ressecção não demonstrou ser um preditor independente (HR = 0,757; p = 0,653). Conclusões: Nosso estudo não identificou a margem de ressecção como fator prognóstico independente; a maioria dos artigos publicados anteriormente não tem escolhas metodológicas unânimes e as coortes de pacientes analisados não são fáceis de comparar. Para chegar a uma concordância unânime em relação ao valor prognóstico da margem de ressecção, seria necessário fazer metanálises em estudos que compartilham a definição da margem de ressecção, metodologia e escolhas terapêuticas pós-operatórias.

Background: The relationship between nasal functions and middle ear surgery is still under debate. Nasal obstruction is considered as a negative prognostic factor in middle ear surgery. This is based on the theory that it may cause Eustachian tube dysfunction (ETD) by leading to reduced ventilation of the middle ear, as found in several patients with nasal septal deviation, chronic rhinitis and nasal polyps. Objectives: To assess how the subjective feeling of nasal function, evaluated by a preoperative questionnaire, may be predictive of surgical outcome and/or risk of failure in middle ear surgery. Methods: We prospectively evaluated data of patients undergoing middle ear surgery for chronic otitis media with and without cholesteatoma. All patients completed the SNOT-22 and ETDQ-7 questionnaires. They underwent surgery for their pathology, as appropriate. Results: The SNOT-22 score was higher in patients with retraction pocket and in patients whose retraction pockets recurred after surgery (p < 0.05). Patients with higher score at SNOT-22 questionnaire, were more likely to show recurrence of atelectasis aftersurgery. Conclusions: The SNOT-22 questionnaire, administrered before surgical procedure, can help in the identification of patients who are at risk of failure in the post-operative period, as well as ETDQ-7.

Vertigo is not itself a disease, but rather a symptom of various syndromes and disorders that jeopardize balance function, which is essential for daily activities. It is an abnormal sensation of motion that usually occurs in the absence of motion, or when a motion is sensed inaccurately. Due to the complexity of the etiopathogenesis of vertigo, many pharmacological treatments have been tested for efficacy on vertigo. Among these drugs, cinnarizine, usually given together with dimenhydrinate, appears to be the first-line pharmacotherapy for the management of vertigo and inner ear disorders. Based on these considerations, the present non-interventional study aimed to investigate the clinical efficacy and tolerability of a fixed combination of cinnarizine (20 mg) and dimenhydrinate (40 mg) in patients suffering from vertigo-related symptoms. To this end, we enrolled 120 adults—70 males, and 50 females—with an average age of 64 years. Before beginning pharmacological treatment, all patients were screened for the intensity of vertigo, dizziness, and concomitant symptoms through the Visual Scale of Dizziness Disorders and Dizziness Handicap Inventory scales. At the end of the anamnestic evaluation, patients received the fixed-dose combination of cinnarizine (20 mg) plus dimenhydrinate (40 mg) 3 times daily, for 60 days. The results of this study provide further insight regarding the efficacy of the fixed combination when used to reduce symptoms of vestibular vertigo of central and/or peripheral origin, after both the 15- and 60-day therapies. Independent of the type of vertigo, the fixed combination was able to reduce dizziness- and vertigo-associated symptoms in more than 75% of all patients treated, starting from 15 days of therapy, and improving 60 days after starting the therapy. Interestingly, we also found differences between male and female patients in the framework of the pharmacological effects of therapy. This study provides further details concerning the therapeutic efficacy of the fixed combination of cinnarizine and dimenhydrinate, and also focuses attention on the possibility that these drugs could act in a gender-specific manner, paving the way for further research.

Migraine vertigo (MV) and Ménière's disease (MD) share several signs and symptoms such as tinnitus, fullness, photophobia, phonophobia, headache and vertigo spells lasting hours.The aim of the present study was to prospectively observe patients with MV with a sporadic audiological symptom evaluated with clinical examination, Vestibular Evoked Myogenic Potentials (VEMPs), ECochG and v-HIT.The finding of VEMP asymmetry, according to our cut-off of 33% of difference between sides, resulted in 20 cases, of which 6 had asymmetry of both c-VEMPs and o-VEMPS, all with development of fluctuating hearing during follow-up. ECochG was positive for endolymphatic hydrops in 12 patients.The evolution of MV may have a variable course in which some patients may develop symptoms typical of MD. The two diseases may be contextually present at the same time configuring an overlapping syndrome, and asymmetric VEMPs might predict development of fluctuating hearing.Evoluzione dell’emicrania vestibolare in sindrome da sovrapposizione con la malattia di Ménière: ruolo prognostico degli esami strumentali.La vertigine emicranica e la malattia di Ménière condividono diversi segni e sintomi come acufeni, ovattamento auricolare, fonofobia, cefalea e crisi di vertigine della durata di ore.Lo scopo dello studio è stato quello di valutare prospetticamente i pazienti con vertigine emicranica e manifestazioni audiologiche sporadiche, mediante esame clinico, VEMPs, ECOchG, v-HIT.Il riscontro di asimmetria dei VEMPs, secondo il limite del 33% di differenza tra i due lati, si è avuto in 20 casi dei quali: 6 con asimmetria di ocular e cervical VEMPs e sviluppo di fluttuazione uditiva nel corso del follow-up. L’ECochG ha riscontrato un’idrope endolinfatica in 12 pazienti.L’evoluzione della vertigine emicranica durante la vita del paziente può avere un decorso variabile nel quale alcuni di essi possono sviluppare sintomi tipici della malattia di Meniere. Le due malattie possono essere contestualmente presenti configurando la sindrome da sovrapposizione e l’asimmetria di entrambi i VEMPs potrebbe predire lo sviluppo della fluttuazione uditiva.

(1) Background: Inferior turbinates&rsquo, hypertrophy is often associated with Eustachian tube dysfunction (ETD), radiofrequency turbinate reduction (RTR) may provide a long-term improvement of nasal obstruction and ETD-related symptoms. (2) Aim: The study aimed to compare ETD in atopic and non-atopic patients before and after RTR and to investigate the correlation between tympanometry and Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7). (3) Methods: Ninety-seven patients, ranging from 33 to 68 years old, were screened by skin tests and divided into atopic (G1) and non-atopic (G2). Eustachian tube function (ETF) was evaluated through tympanometry, William&rsquo, s test and ETDQ-7. (4) Results: A moderate to severe subjective ETDQ-7 was found in the 35.42% of G1 and in the 22.45% of G2 patients before RTR. William&rsquo, s test resulted normal in 141 ears (72.68%), partially impaired in 15 (7.73%), and grossly impaired in 38 (19.59%) before surgery. A grossly ETD was evidenced in the 19.59% of cases before surgery and decreased to 6.18% after surgery with a significant difference among atopic patients (p &lt, 0.001). (5) Conclusion: RTR may be considered a treatment option in patients suffering from ETD and inferior turbinates&rsquo, hypertrophy, RTR reduced the percentage of grossly impaired ET function (p &lt, 0.001). ETDQ-7 and William&rsquo, s test may represent valuable tools to assess ET function before and after surgery.

To investigate the role of the period of emergence of the first words and its interactions with other risk factors in predicting the development of speech sound disorder (SSD) among 4- to 5-year-old children.After 373 children underwent otolaryngology and speech pathology examinations, their parents answered a questionnaire about potential risk factors for speech impairment. The presence of SSD was identified by a speech pathologist who administered Fanzago's Articulation Test to each child. Multivariate logistic analysis was used to explore the relationships between variables and outcomes.Mean age at first words was 17.8 ± 6.5 months of life; 25.7% of patients suffered from SSD, and 3.7% from stuttering. A family history of language impairment was found in 12.9% of the sample, whereas a family history of reading difficulty was reported in only 5.4% of cases. No differences in terms of mean age (p = 0.3) or gestational age (p = 0.16) were found between children affected by SSD and those who were not. Multivariate logistic analysis revealed that male sex (p 0.001), a family history of language impairment (p 0.001) and stuttering (p = 0.001) were significantly associated to SSD. Age at first words did not result a predictor of speech impairment.In contrast to male sex (p 0.001), family history of language impairment (p 0.001) and stuttering (p = 0.001) which resulted significantly associated to SSD, age at first words does not seem to be a predictor of SSD (p = 0.11); however, it remains a useful indicator of language delay and, when considered in association with other language milestones, can be a reason of concern for parents and caregivers about their children's developmental and speech therapy needs.

Objective: To investigate the relationship between haematological routine parameters and audiogram shapes in patients affected by sudden sensorineural hearing loss (SSNHL). Design: A retrospective study. All patients were divided into four groups according to the audiometric curve and mean values of haematological parameters (haemoglobin, white blood cell, neutrophils and lymphocytes relative count, platelet count, haematocrit, prothrombin time, activated partial thromboplastin time, fibrinogen and neutrophil-to-lymphocite ratio) of each group were statistically compared. The prognostic role of blood profile and coagulation test was also examined. Study sample: A cohort of 183 SSNHL patients without comorbidities. Results: With a 48.78% of complete hearing recovery, individuals affected by upsloping hearing loss presented a better prognosis instead of flat (18.36%), downsloping (19.23%) and anacusis (2.45%) groups (p = 0.0001). The multivariate analysis of complete blood count values revealed lower mean percentage of lymphocytes (p = 0.041) and higher platelet levels (p = 0.015) in case of downsloping hearing loss; with the exception of fibrinogen (p = 0.041), none of the main haematological parameters studied resulted associated with poorer prognosis. Conclusions: Our work suggested a lack of association between haematological parameters and a defined audiometric picture in SSNHL patients; furthermore, only fibrinogen seems to influence the prognosis of this disease.

Temporomandibular disorders such as bruxism may cause painful clinical conditions and over time lead to chronic facial pain. A combination of therapeutic strategies that are usually undertaken by dentists and gnathologists to reduce bruxism episodes and consequently pain, are myofunctional therapy, pharmacological treatment, intraoral interventions and behavioural treatments. The aim of this work was to understand if myofuntional therapy alone can be a useful therapy for the reduction of chronic facial pain. 24 patients, 9 male and 15 female, age ranging between 25 and 45, were treated with a myofunctional therapy for 9 month. Each patient was evaluated through a numeric pain intensity scale ranging from 0 to 10 and the number of bruxism episodes/hour per patient were also recorded; electromyographic examinations of the temporal, masseter, sternocleidomastoid and digastric muscles were performed to evaluate muscle activation. Each patient was tested before (T0) and after (T1) the treatment period. Pain intensity decreased from T0 to T1 (8.13±0.39 vs. 1.75±2.43, respectively, p

Objective: To evaluate the frequency of GJB2 mutations and their correlation with phenotype in Sicilian non-syndromic sensorineural hearing loss (NSHL) patients. Design: Sequencing of the coding region, basal promoter, exon 1, and donor splice site of the GJB2 gene; screening for the presence of the two common GJB6 deletions. Study sample: A cohort of 102 Sicilian NSHL patients. Results: Fifteen different mutations in GJB2 and seventeen different genotypes were detected. No GJB6 mutations were found. The hearing impairment was profound in the 64.72% of probands (mean PTA 0.25 – 4 kHz of 88.82 26.52 dB HL). A total of 81.37% of patients harboured at least one c.35delG allele; c.167delT and c.-23 1G A were identifi ed in 10.78% and the 9.8% of patients respectively; c.35delG homozygotes presented more severe hearing impairment (75.59% of profound hearing loss) and a higher mean PTA 0.25 – 4 kHz (96.79 21.11 dB HL) with respect to c.35delG/non-c.35delG and c.35delG/Wt patients (P 0.05). Conclusions: This work underlines the role of c.35delG, c.167delT and c.-23 1G A as the most frequent causes of NSHL in Sicily. The c.35delG frequency found is similar to those reported in other populations of the Mediterranean area. The analysis of genetic and audiologic data confi rmed a variability in the phenotype associated to a single genotype.

The main purpose of this study was to describe a novel missense mutation (p.D179H) found in a Western Sicily family and to examine the genetic and audiologic profiles of all family members by performing a GJB2 and GJB6 mutations analysis and a complete audiologic assessment. The proband was a 3-month-old infant with a congenital profound sensorineural hearing loss; direct sequencing of the GJB2 revealed the presence of a c.35delG mutation in the heterozygous state and a heterozygous G[C transition at nucleotide 535 in trans; this novel mutation, called p.D179H, resulted in an aspartic acid to histidine change at codon 179. It was also evidenced in the heterozygous state in two members of this family, both with normal hearing. No GJB6 mutations were evidenced in all subjects studied. Considering the genotypic and phenotypic analysis of all family members, we suggest, differently from the p.D179 N mutation previously reported, a recessive mode of inheritance. Functional studies on p.D179H have to be performed to confirm our hypothesis.

The aims of this study were to determine the distribution of risk factors associated with tinnitus analysing their role in the development of tinnitus and the effects of their interaction; to evidence the importance of a suitable and adequate clinical and audiologic assessment to avoid those modifiable risk factors responsible for cochlear dysfunction and tinnitus onset. 46 subjects with tinnitus and 74 controls were studied according to: age, sex, Body Mass Index (BMI), neck circumference, tobacco smoking, feeling fatigue or headache, self reporting snoring, hypertension, diabetes, coronary heart disease, and/or hyperlipidemia, and laboratory finding as lipid profile and levels of reactive oxygen metabolites (d-ROM). Audiological assessment was performed by multi-frequency audiometry (PTA0.5–16 kHz) and transient-evoked otoacoustic emissions (TEOAE diagnostic). Univariate analysis was performed to examine the association between determinants and occurrence of tinnitus; Mantel–Haenszel test (G.or) was used to investigate the joint effect of determinants on tinnitus. Tinnitus was more frequent among males with age >50 years; BMI >30 kg/m2, neck circumference >40 cm, headache, hypertension, hypercholesterolemia resulted significant risk factors for tinnitus (P < 0.0001). Tinnitus group had more comorbidity (P < 0.0001) and worse audiometric thresholds (60.87 Vs 21.62 % hearing loss; P < 0.0001) with respect to control group. The interaction between hypertension–BMI ≥ 30 kg/m2 (G.or = 8.45) and smoking–hypercholesterolemia (G.or = 5.08) increases the risk of tinnitus (P < 0.0001). Our results underline that several factors either individually or jointly contribute to tinnitus onset; a comprehensive knowledge about tinnitus risk factors and associated clinical conditions could contribute to minimizing this disorder.

Newborn hearing screening is a type of screening testfor the early detection of hearing loss. It can recognizewith good accuracy newborns affected by hearingimpairment allowing an early diagnosis and interventionand avoiding cognitive and linguistic deficits [1-6].The incidence of bilateral sensorineural hearing loss(SNHL) in Sicily is 2.35 cases per 1000 newborns; thisvalue increases to 2.95 if we consider also unilateral SNHL[2,3] and to 10 cases per 1000 births among infants at risk[7-9].A correct newborn hearing screening programme isbased on different protocols depending on the presence/absence of audiologic risk factors:† Newborns without risk factors: [1-3]Initial Hearing Screening (Step I):The initialscreening should be performed using Transient-Evoked Otoacoustic Emissions (TEOAEs) in the birthcenters as close to discharge as possible, preferably 12hours or more after birth. It is recommended that aninfant be referred for a re-screening (step 2) if s/hedoes not pass the initial screening or results cannot beobtained in one or both ears.Re-screening (Step II):The re-screening should beperformed in a second level center using TEOAEs andAutomated Auditory Brainstem Response (AABR). Ifan infant does not pass the re-screening or if resultscannot be obtained in one or both ears, s/he shall bereferred to the regional third level center for diagnosticaudiological evaluation.† Newborns with risk factors (JCIH 2007) [7-10]Initial Hearing Screening (Step I): The Initial Hear-ing Screening should be performed in a second levelcenter using TEOAEs and AABR. If an infant does notpass the initial screening or if results cannot beobtained in one or both ears, s/he shall be referred tothe regional third level center for diagnostic audiologi-cal evaluation.Screening variablesActually TEOAEs have a sensitivity of 100% and a specifi-city of about 70-95%. A higher TEOAEs specificity valuedepends on [1,2,11]:† Timing of TEOAEs recording† Trained and qualified personnel† PASS/REFER criteriaLimitations of screeningAudiologic screening does not identify:† Post-natal SNHL (prelingual or perilingual) ,mainly related to genetic causes [12,13]† ANSD (Auditory Neuropathy Spectrum Disorder):the main risk factors associated to ANSD are severejaundice, prematurity, respiratory distress, ototoxicdrugs (used to treat neonatal infections), genetic muta-tions (e.g. OTOF gene). The diagnosis of ANSD isusually based on the combination of absent or abnor-mal ABR with normal TEOAESs and/or cochlearmicrophonics (CM) [14].

Introduction: To date intracranial complication caused by tooth extractions are extremely rare. In particular parietal subdural empyema of odontogenic origin has not been described. A literature review is presented here to emphasize the extreme rarity of this clinical entity. Case presentation: An 18-year-old Caucasian man with a history of dental extraction developed dysarthria, lethargy, purulent rhinorrhea, and fever. A computed tomography scan demonstrated extensive sinusitis involving maxillary sinus, anterior ethmoid and frontal sinus on the left side and a subdural fluid collection in the temporal-parietal site on the same side. He underwent vancomycin, metronidazole and meropenem therapy, and subsequently left maxillary antrostomy, and frontal and maxillary sinuses toilette by an open approach. The last clinical control done after 3 months showed a regression of all symptoms. Conclusions: The occurrence of subdural empyema is an uncommon but possible sequela of a complicated tooth extraction. A multidisciplinary approach involving otolaryngologist, neurosurgeons, clinical microbiologist, and neuroradiologist is essential. Antibiotic therapy with surgical approach is the gold standard treatment.

Objectives: To describe audiometric characteristics and speech perception performances of prelingually deaf Sicilian children after cochlear implantation; to identify the influence of cochlear implant (CI) user and family's characteristics on speech recognition and intelligibility outcomes. Methods: Twenty-eight infants with a congenital or acquired hearing impairment and implanted before the 3rd year of life were studied; all children suffered from bilateral sensorineural hearing loss (SNHL) with evidence of lack of hearing aids benefit and no evidence of intellectual disability. The study of the main characteristics associated with CI user and family's profile was performed with a clinical assessment including pre-implant and post-implant (1, 3, 6, 12 and 18 months) behavioural audiometry (evaluating average threshold for the frequencies 0.5, 1, 2 and 4 KHz) and speech recognition tests (IT-MAIS, MUSS, CAP and SIR). Results: Our cohort was characterized by an early diagnosis of SNHL (5.77 and 12.17 months for congenital and acquired HL respectively), a short length of deafness (average = 6.78 months) and an implantation before the 3rd year of life (mean = 24.25 months; range from 10 to 36). Analysis of audiometric threshold revealed a significantly improved capacity to detect sounds within the conversational speech spectrum after 12 months from implantation (r = 0.99; p < 0.001). The main speech recognition test evidenced speech perception and speech intelligibility performances (CAP median value of 3; SIR category = 3 in 46.42%) equal to those children with same characteristics reported by literature. With the exception of 'daily CI use' (p < 0.001), none of the variables associated with CI user and family's profile resulted significant predictor of speech perception improvement. Conclusions: This work demonstrates that all children of our cohort, with an early diagnosis of SNHL and a CI surgery performed before the 3rd year of life, presented a progressive audiometric and speech improvement through the first 12-18 months after cochlear implantation. The study also highlights that, differently from the others variables studied, a continuous CI use influences significantly speech perception and recognition outcomes.

The objective of this work was to evaluate the prevalence of sensorineural hearing loss (SNHL) and distribution of the main risk factors associated to it focusing on their role in the development of deafness and their interaction. We performed a global audiological assessment (through TEOAE, tympanometry and ABR) in 508 infants at risk studying the main risk factors reported by Joint Committee on Infant Hearing (2007). Fifty-one infants (10.03 %) were diagnosed with SNHL (45 bilateral and 6 unilateral) with a mean hearing threshold of 87.39 ± 28.25 dB HL; family history of hearing impairment (HI) and TORCH infections indicated independent significant risk factors (P < 0.00001 and P = 0.024, respectively). High SNHL percentages were evidenced also in NICU babies, due to the various pathologies and risk factors presented by these infants, and among newborns who suffered from hyperbilirubinemia (11.97 and 9.52 %, respectively). The mean degree of hearing loss for children with family history of HI (>100 dB HL) emphasizes the necessity of an early diagnosis to avoid the consequences of auditory deprivation. Craniofacial abnormalities and syndromes associated to HI showed an important relationship (P < 0.00001) with conductive hearing loss. A progressive increase was evidenced in SNHL incidence as the number of risk factors rises (from 5.12 for 2 risk factors to 28.5 % for 5 or more) with a significant difference among the groups (P = 0.049); multiple risk factors showed an additional cofactor for HL (r2 = 0.93). Considering the high SNHL prevalence (10.03 %) in infants at risk, this study highlights the necessity to implement a neonatal hearing screening program in Western Sicily.

Objective: To identify the incidence of sensorineural hearing loss (SNHL) on infant at risk and to classify the degree and type of hearing loss describing the main causes associated in Western Sicily. To compare single TEOAE and combined TEOAE/ABR techniques studying the referral rate, the false-positive and false-negative rates through concordance test (κ coefficient), sensitivity (TPR) and specificity (TNR) for each protocol. Methods: From January 2010 to June 2011, 412 infants at risk, ranging from 4 to 20 weeks of life, transferred to Audiology Department of Palermo from the births centers of Western Sicily, underwent to audiological assessment with TEOAE, tympanometry and ABR. The following risk factors were studied: family history of SNHL, consanguinity, low birth weight, prematurity, cranio-facial abnormality and syndromes associated to SNHL, respiratory distress, intensive care in excess of 5 days (NICU), pregnant maternal diseases, perinatal sepsis or meningitis, hyperbilirubinemia, ototoxic drugs administration. Results: Forty-seven infants (11.41%) were diagnosed with SNHL; median corrected age at final audiological diagnosis was 12 weeks. SNHL resulted moderate in 44.68%, severe in 10.64% and profound in 21 cases with a significant difference in family history and NICU infants (p < 0.0001). As the number of coexisting risk factors increases, the percentage value of SNHL in infants (χ 2 = 12.31, p = 0.01, r 2 = 0.98) and the degree of hearing loss (χ 2 = 13.40, p = 0.0095, r = 0.92) also increase. The study of single TEOAE and combined TEOAE/ABR showed a statistical difference (χ 2 = 14.89, p < 0.001) with a low concordance value (κ = 0.87) confirming the importance of combined techniques for NICU group (κ = 0.86) where four cases (0.97%) of auditory neuropathy were diagnosed. Conclusion: This study demonstrates the necessity to implement a neonatal hearing screening program in Western Sicily because of the high percentage of SNHL in infants at risk. Family history of HL is an independent significant risk factor for SNHL easily diagnosed through single TEOAE technique. Combined TEOAE/ABR is the gold standard for NICU babies which are at risk for auditory neuropathy. Coexisting risk factors are an additional risk factor for HL.

INTRODUCTION: Upper respiratory tract infection is a nonspecific term used to describe an acute infection involving the nose, paranasal sinuses, pharynx and larynx. Upper respiratory tract infections in children are often associated with Eustachian tube dysfunction and complicated by otitis media, an inflammatory process within the middle ear. Environmental, epidemiologic and familial risk factors for otitis media (such as sex, socioeconomic and educational factors, smoke exposure, allergy or duration of breastfeeding) have been previously reported, but actually no data about their diffusion among Sicilian children with upper respiratory tract infections are available. OBJECTIVE: To investigate the main risk factors for otitis media and their prevalence in Sicilian children with and without upper respiratory tract infections. METHODS: A case-control study of 204 children with upper respiratory tract infections who developed otitis media during a 3 weeks monitoring period and 204 age and sex-matched healthy controls. Seventeen epidemiologically relevant features were inventoried by means of standardized questionnaires and skin tests were performed. Univariate analysis and multivariate logistic regression analysis were used to examine the association between risk factors and occurrence of otitis media. RESULTS: Otitis media resulted strongly associated to large families, low parental educational attainment, schooling within the third years of life (p < 0.05); children were more susceptible to develop otitis media in the presence of asthma, cough, laryngopharyngeal reflux disease, snoring and apnea (p < 0.05). Allergy and urban localization increased the risk of otitis media in children exposed to smoke respectively of 166% and 277% (p < 0.05); the joint effect of asthma and presence of pets in allergic population increased the risk of recurrence of 11%, while allergy, cough and runny nose together increased this risk of 74%. CONCLUSIONS: Upper respiratory tract infections and otitis media are common childhood diseases strongly associated with low parental educational attainment (p = 0.0001), exposure to smoke (p = 0.0001), indoor exposure to mold (p = 0.0001), laryngopharyngeal reflux disease (p = 0.0002) and the lack of breast-feeding (p = 0.0014); an increased risk of otitis media recurrences was observed in the presence of allergy, persistent cough and runny nose (p = 0.0001). The modification of the identified risk factors for otitis media should be recommended to realize a correct primary care intervention. RESUMO INTRODUÇÃO: A infecção de vias aéreas superiores é uma denominação inespecífica, empregada na descrição de uma infecção aguda envolvendo o nariz, os seios paranasais, a faringe e a laringe. As infecções de vias aéreas superiores em crianças estão frequentemente associadas à disfunção da trompa de Eustáquio, complicando-se com otite média, um processo inflamatório da orelha média. Já foram relatados vários fatores de risco relacionados à otite média, incluindo os ambientais, epidemiológicos e familiares (p. ex., gênero, fatores socioeconômicos e educacionais, exposição ao tabaco, alergia ou duração do aleitamento materno), entretanto, não dispomos de dados sobre sua ocorrência entre crianças sicilianas com infecções de vias aéreas superiores. OBJETIVO: Investigar os principais fatores de risco para otite média e sua prevalência em crianças sicilianas com e sem infecções de vias aéreas superiores. MÉTODO: Um estudo de caso-controle de 204 crianças com infecções de vias aéreas superiores apresentando otite média durante um período de monitoração de três semanas e 204 controles saudáveis compatíveis em idade e gênero. Foram relacionadas 17 características com relevância epidemiológica por meio da aplicação de questionários padronizados; também foram realizados testes cutâneos. Foram utilizadas análises univariada e de regressão logística multivariada no exame da associação entre fatores de risco e ocorrência de otite média. RESULTADOS: A otite média revelou forte associação com famílias numerosas, baixo nível educacional dos pais e escolaridade no terceiro ano de vida (p< 0,05); as crianças demonstraram maior suscetibilidade para ocorrência de otite média em presença de asma, tosse, doença do refluxo laringofaríngeo, ronco e apneia (p < 0,05). Alergia e localização urbana aumentaram o risco de otite média em crianças expostas ao fumo em 166% e 277% (p < 0,05), respectivamente; o efeito conjunto de asma e presença de animais de estimação na população alérgica aumentou o risco de recidiva em 11%, enquanto que, em conjunto, alergia, tosse e coriza aumentaram esse risco em 74%. CONCLUSÕES: As infecções de vias aéreas superiores e otite média são doenças pediátricas comuns, fortemente associadas a baixo nível educacional dos pais (p = 0,0001), exposição ao fumo (p = 0,0001), exposição domiciliar ao mofo (p = 0,0001), refluxo laringofaríngeo (p = 0,0002) e ausência de aleitamento materno (p = 0,0014). Também foi observado aumento do risco de recidivas de otite média em presença de alergia, tosse persistente e coriza (p = 0,0001). Deve-se recomendar a modificação dos fatores de risco identificados para otite média, para uma correta intervenção terapêutica primária.
