Background and purpose Using functional magnetic resonance imaging (fMRI), we explored cortical activation in patients with acute Bell's palsy (BP) and analyzed its correlates with clinical status in the acute phase, and with 6-month outcome. Methods Twenty-four right-handed patients with acute BP within 15 days of onset and 24 healthy controls underwent fMRI during performance of unilateral active (hemi-smiling) and passive lip movement tasks with both the paretic and the normal lip. The degree of paresis was evaluated during the acute stage and at the 6-month follow up using the House-Brackmann (HB) grading scale. Complete recovery was defined as HB grade II or less at the end of the 6-month period. The difference in the HB grade (ΔHB) between the acute stage and the 6-month follow up was used to evaluate clinical improvement. Results There were 24 patients with unilateral acute BP. HB grades ranged from III to VI. At 6 months, 11 patients (46%) had completely recovered and 12 (50%) were partially improved. Compared with healthy subjects, BP patients had a significantly greater activation of the frontal areas and the insula ipsilateral to the paretic side. In BP patients, there was an inverse correlation between the activation of the ipsilateral hemisphere when moving the paretic side and the degree of paresis at baseline. An association was also observed between activation and clinical outcome (both complete recovery and ΔHB). Conclusions In patients with BP, fMRI may represent a useful tool to predict long-term outcome, guide therapeutic approach, and monitor treatment response.

The aim of this retrospective study is to evaluate the results obtained with CO2 TOLMS in patients with Tis, T1, and T2 glottic tumors at our Department from 2004 to 2016 treated with CO2 TOLMS. One hundred eighty-five patients having a median age of 67 years (range 42–88) were included in the present analysis. The tumor stages of the patients included 134 pTis-T1a, 12 pT1b, and 39 pT2 cases. Median duration of follow-up for the whole study cohort was 55 months (range 24–108 months). At 5-year follow-up, local control was 91%, 83%, and 79.4% for T1a, T1b, and T2 respectively. Disease-specific survival was 95.5%, 91.6%, and 92.3%. Overall survival was 73.8%, 91.6%, and 82%, and larynx preservation was 96.2%, 83%, and 84.6%. This study confirms that CO2 TOLMS is a safe and standard therapy for selected T1 and T2 glottic carcinoma, and our review on T2 glottic cancer suggests that CO2 TOLMS represents a reliable option in terms of overall survival, disease-specific survival, and laryngeal preservation. However, patients with anterior commissure involvement and T2 cancer should be evaluated with a preoperative MRI in order to exclude the infiltration of the laryngeal framework and to quantify the neoplastic involvement of para-glottic space.

Meniere's Disease (MD) is an inner ear disorder characterized by spontaneous recurrent vertigo, fluctuating sensorineural hearing loss, aural fullness and low-pitch tinnitus. Therapeutic management of MD includes dietary restriction and medical therapy. A minority of cases is characterized by frequent vertigo attacks, progressive hearing loss and persistent tinnitus even through the continuous medical treatments; this condition is called intractable MD and requires a therapeutic escalation from non-invasive medical treatment to surgical intervention. Invasive procedures include endolymphatic sac surgery, vestibular nerve section and labyrinthectomy. These procedures have a very high success rate on symptom control but may have a severe impact on the hearing function. However, the simultaneous combined approach of demolitive surgery and cochlear implantation may be a valid approach to treat symptoms of intractable MD and preserve hearing function. In the present study, we review current literature focusing on intractable MD to describe and discuss advantages and disadvantages of established and newly proposed surgical treatments for intractable MD.

Amyloidosis constitutes a large spectrum of diseases characterized by an extracellular deposition of a fibrillar aggregate, generating insoluble and toxic amasses that may be deposited in tissues in bundles with an abnormal cross-β-sheet conformation, known as amyloid. Amyloid may lead to a cell damage and an impairment of organ function. Several different proteins are recognized as able to produce amyloid fibrils with a different tissue tropism related to the molecular structure. The deposition of amyloid may occur as a consequence of the presence of an abnormal protein, caused by high plasma levels of a normal protein, or as a result of the aging process along with some environmental factors. Although amyloidosis is rare, amyloid deposits play a role in several conditions as degenerative diseases. Thus, the development of antiamyloid curative treatments may be a rational approach to treat neurodegenerative conditions like Alzheimer's disease in the future. Nowadays, novel treatment options are currently refined through controlled trials, as new drug targets and different therapeutic approaches have been identified and validated through modern advances in basic research. Fibril formation stabilizers, proteasome inhibitors, and immunotherapy revealed promising results in improving the outcomes of patients with systemic amyloidosis, and these novel algorithms will be effectively combined with current treatments based on chemotherapeutic regimens. The aim of this review is to provide an update on diagnosis and treatment for systemic amyloidosis.

OBJECTIVE Immune-mediated inner ear disease (IMIED) might cause severe/profound hearing loss and these patients are considered ideal candidates to cochlear implant (CI) surgery. The aim of the study was to evaluate impedance changes over time. METHOD The Study Group (SG) was composed of CI IMIED patients (31 ears) and a Control Group (CG) of CI patients with hearing loss not related to their immune system (31 ears). Audiological performance and impedance values were measured and compared amongst groups at 3, 6, 12 and 18 months following the fitting sessions. RESULTS Speech perception was significantly better for SG in word and sentence recognition in quiet. Impedance values were, on average, significantly higher for apical and middle electrode segments in SG compared to CG at the 3- month follow-up and were maintained over time. Additionally, a subset of SG patients (active patients) experienced significantly greater impedance fluctuation corresponding to clinical symptom reactivation. CONCLUSION IMIED patients achieve good audiological performance. However, the relapsing inflammation could change the inner ear environment, causing impedance fluctuations and, consequently, more frequent CI fittings. Additionally, impedance evaluation could be utilized as an early warning sign of IMIED recurrence and as an aid to therapeutic decision-making.

Bimodal stimulation is a standard option for asymmetric hearing loss in adults. Questions have been raised whether receiving two stimulations may conflict in elderly listeners where the central integration of an acoustic/electrical signal may be very important to obtain benefit in terms of speech perception.Clinical retrospective study.The outcomes from 17 bimodal cochlear implant (CI) users were analysed. The test material consisted of speech audiometry in quiet and in noise (STARR and Matrix).Bimodal PTA and speech perception both in quiet and in noise were significantly better than CI or HA alone. Age showed a significant effect on bimodal STARR outcomes. Similarly, bimodal STARR scores improved significantly in comparison to Better Ear.Both Matrix and STARR tests were very difficult for many elderly CI listeners from the present study group, especially in unilateral listening condition. The performance improved significantly, emphasising a good integration of acoustic and electric hearing in this group of elderly bimodal listeners. Overall results highlighted how a specific study, based on speech perception in noise in the elderly listeners, might shed light on the effect of speech test modality on bimodal outcomes.

Introduction: The aim of the current systematic review is to update the pooled survival outcome of patients with T2 glottic carcinoma treated with either laser surgery (CO2 transoral laser microsurgery [CO2 TOLMS]), radiotherapy (RT), or open partial laryngectomy (OPL). Methods: A systematic search was performed using the MEDLINE database, Scopus, and Google scholar. The inclusion criteria were studies of patients with T2N0 glottic tumor, treated with either primary CO2 TOLMS, definitive curative RT, or primary OPL, and with reported oncological outcome at 5 years calculated with a Kaplan-Meier or Cox regression method. Results: The results of the current review show that local control (LC) is higher with OPL 94.4%, while there are no differences in LC at 5-year posttreatment for patients treated with RT, compared to those treated with CO2 TOLMS (respectively, 75.6% and 75.4%). Primary treatment with OPL and CO2 TOLMS results in higher laryngeal preservation than primary treatment with RT (respectively 95.8%, 86.9%, and 82.4%). Conclusion: First-line treatment with OPL and CO2 TOLMS should be encouraged in selected T2 patients, because it results in higher laryngeal preservation and similar LC compared to primary treatment with RT. The involvement of the anterior commissure in the craniocaudal plane and T2b impaired vocal cord mobility have a poorer prognosis and LC compared to patients with T2a tumors for both CO2 TOLMS and RT.

BackgroundCongenital cytomegalovirus (cCMV) infection is the most frequent non-genetic cause of sensorineural hearing-loss (SNHL) (i.e., hearing loss due to a cochlear and/or auditory nerve damage). It is widely accepted that SNHL at birth, when associated to cCMV symptomatic infection involving the central nervous system, benefits from antiviral therapy started in the neonatal period. Conversely, there is no consensus for antiviral treatment in congenitally infected infants diagnosed with isolated SNHL (i.e., SNHL in an otherwise asymptomatic infant) at birth.Our aim was to assess the frequency and the auditory outcome of isolated SNHL at birth due to auditory neuropathy (AN) (i.e., SNHL in a patient with normal cochlear function and auditory nerve dysfunction) in infants with cCMV infection.MethodsWe retrospectively reviewed the clinical history of 60 infants, born at term, with cCMV asymptomatic infection, without additional risk factors for SNHL, and exhibiting bilateral “pass” otoacustic emissions (OAE). None of them underwent antiviral therapy.Hearing thresholds were assessed by means of Auditory Brainstem Responses (ABR). AN affected children were followed up until possible normalization of the hearing thresholds or definitive diagnosis of AN. Each infant diagnosed with monolateral or bilateral AN was classified according to the worst ear threshold.ResultsIn our population, the first ABR was performed at a mean age of 5.00 ± 2.79 (SD) months and AN was diagnosed in 16/60 (26.67%) infants; in 4 infants the AN was defined as mild (4/4 monolateral), moderate in 11 (5/11 bilateral), and severe in 1 (bilateral). The mean age at first ABR was 3.69 ± 2.80 (SD) months in the 16 babies with AN and 5.48 ± 2.66 (SD) months in the 44 infants with normal hearing (p = 0.007). All AN cases spontaneously recovered a normal auditory threshold over time. The mean length of the audiological follow-up was 32.44 ± 17.58 (SD) months (range 5–60 months).ConclusionA delayed maturation of the auditory pathways should be considered when a mild/moderate isolated AN at birth is detected in cCMV infected infants. Prospective studies conducted on larger populations, and with a longer audiological follow-up, are needed to confirm our findings.

Objective The aim of the present study was to investigate the pupillary response to word identification in cochlear implant (CI) patients. Authors hypothesized that when task difficulty (i.e. addition of background noise) increased, pupil dilation markers such as the peak dilation or the latency of the peak dilation, would increase in CI users, as already observed in normal-hearing and hearing-impaired subjects. Methods Pupillometric measures in ten CI patients were combined to standard speech recognition scores used to evaluate CI outcomes, namely speech audiometry in quiet and in noise at +10 dB signal-to-noise ratio. The main outcome measures of pupillometry were mean pupil dilation, maximal pupil dilation, dilation latency and mean dilation during return to baseline or retention interval. Subjective hearing quality was evaluated by means of one self-reported fatigue questionnaire, and the Speech, Spatial and Qualities (SSQ) of Hearing scale. Results All pupil dilation data were transformed to percent change in event-related pupil dilation (ERPD, %). Analyses show that the peak amplitude for both mean pupil dilation and maximal pupil dilation were higher during the speech-in-noise test. Mean peak dilation was measured at 3.47 +/- 2.29 % noise vs. 2.19 +/- 2.46 in quiet and maximal peak value was detected at 9.17 +/- 3.25 % in noise vs. 8.72 +/- 2.93% in quiet. Concerning the questionnaires, the mean pupil dilation during the retention interval was significantly correlated with the spatial subscale score of the SSQ Hearing scale (r(8) = -.84, p =0023), and with the global score (r(8) = -.78, p=0.0018). Conclusions The analysis of pupillometric traces, obtained during speech audiometry in quiet and in noise in CI users, provided interesting information about the different processes engaged in this task. Pupillometric measures could be indicative of listening difficulty, phoneme intelligibility, and were correlated with general hearing experience as evaluated by the Speech, Spatial and Qualities of Hearing scale. These preliminary results show that pupillometry constitutes a promising tool to improve objective quantification of CI performance in clinical settings.

Unilateral noise-induced hearing loss reduces the input to the central auditory pathway disrupting the excitatory and inhibitory inputs to the inferior colliculus (IC), an important binaural processing center. Little is known about the compensatory synaptic changes that occur in the IC as a consequence of unilateral noise-induced hearing loss. To address this issue, Sprague-Dawley rats underwent unilateral noise exposure resulting in severe unilateral hearing loss. IC tissues from the contralateral and ipsilateral IC were evaluated for acute (2-d) and chronic (28-d) changes in the expression of 84 synaptic plasticity genes on a PCR array. Arc and Egr1 genes were further visualized by in situ hybridization to validate the PCR results. None of the genes were upregulated, but many were downregulated post-exposure. At 2-d post-exposure, more than 75% of the genes were significantly downregulated in the contralateral IC, while only two were downregulated in the ipsilateral IC. Many of the downregulated genes were related to long-term depression, long-term potentiation, cell adhesion, immediate early genes, neural receptors and postsynaptic density. At 28-d post-exposure, the gene expression pattern was reversed with more than 85% of genes in the ipsilateral IC now downregulated. Most genes previously downregulated in the contralateral IC 2-d post-exposure had recovered; less than 15% remained downregulated. These time-dependent, asymmetric changes in synaptic plasticity gene expression could shed new light on the perceptual deficits associated with unilateral hearing loss and the dynamic structural and functional changes that occur in the IC days and months following unilateral noise-induced hearing loss.

The association between hyperacusis and developmental disorders such as autism spectrum disorders has been extensively reported in the literature, however, the specific prevalence of hyperacusis in attention deficit hyperactivity disorder (ADHD) has never been investigated. In this preliminary study, we evaluated the presence of hyperacusis in a small sample of children affected by ADHD compared to a control group of healthy children. Thirty normal hearing children with a diagnosis of ADHD and 30 children matched for sex and age were enrolled in the study. All children underwent audiological and multidisciplinary neuropsychiatric evaluation. Hearing was assessed using pure tone audiometry and immittance test, ADHD was diagnosed following the Diagnostic and Statistical Manual of Mental Disorder criteria. Hyperacusis was assessed through the administration of a questionnaire to parents and an interview with children. Hyperacusis was diagnosed in 11 children (36.7%) in the study group and in four children (13.3%) in the control group, this difference was statistically significant (p = 0.03). The preliminary results of this study suggest a higher presence of hyperacusis in children with attention deficit hyperactivity disorder compared to control children. More studies on larger samples are necessary to confirm these results.

Titanium ossicular chain replacement prosthesis is often used for rehabilitation of the columellar effect in otologic surgeries. This retrospective study aims to analyse the anatomical and functional results of surgeries in which a titanium prosthesis was used. Two hundred and eighty procedures in 256 patients operated on in a tertiary referral center were analysed. Aetiologies, preoperative audiograms, peroperative data and postoperative outcomes at 2 and 12 months postoperatively were reviewed. Chronic suppurative otitis media with or without cholesteatoma was the main aetiology (89%). There was no difference in anatomical results between partial and total ossicular replacement prosthesis, with an overall dislocation rate of 6%, and an overall extrusion rate of 3%. Regarding functional results, a postoperative air-bone gap ≤ 20 dB was achieved in 65% of cases, with a better result for partial compared to total ossiculoplasty (p = 0.02). A significant difference in air bone gap closure was found when comparing aetiologies, with a higher air-bone gap closure in malformation cases compared to chronic suppurative otitis media with cholesteatoma or retraction cases (p = 0.03). Ossiculoplasty using titanium prosthesis is a safe and effective procedure for rehabilitation of hearing loss, which allows reaching an air-bone gap ≤ 20 dB in the majority of patients.Risultati anatomici e funzionali dell’ossiculoplastica con protesi in titanio.Le protesi ossiculari in titanio sono sempre più frequentemente utilizzate per ristabilire la continuità della catena ossiculare nella chirurgia otologica. Il presente studio retrospettivo ha come scopo quello di analizzare i risultati anatomici e funzionali di questa tecnica. Sono state studiate 280 procedure di ossiculoplastica con protesi in titanio, realizzate su 256 pazienti in un centro ospedaliero universitario. Sono stati raccolti e analizzati i dati riguardanti l’eziopatogenesi, l’audiometria preoperatoria e i risultati postoperatori anatomici e audiologici a 2 e 12 mesi. La prima patologia riscontrata in ordine di frequenza è stata l’otite cronica con o senza colesteatoma (80% dei casi), ma non è stata riscontrata nessuna differenza significativa nei dati audiologici preoperatori in funzione della patologia. Nel 65% dei casi è stato raggiunto nel postoperatorio un gap aereo ≤ 20 dB, con risultati significativamente migliori nelle ossiculoplastiche parziali rispetto alle totali (p = 0,02). Al contrario, per quanto riguarda i risultati anatomici non è stata riscontrata alcuna differenza utilizzando le protesi parziali o totali, con un tasso globale di dislocazione del 6% e di estrusione della protesi del 3%. È stata trovata una differenza significativa nei risultati audiologici postoperatori in funzione della patologia otologica di base, con una variazione maggiore del gap aereo nei casi di malformazione rispetto ai casi di otite cronica colesteatomatosa o patologia retrattiva (p = 0,03). Ne consegue che il tipo di chirurgia non influenza il risultato postoperatorio. L’ossiculoplastica con protesi in titanio si è rivelata una procedura valida ed efficace che permette un miglioramento dell’udito postoperatorio nella maggior parte dei pazienti.

Background The introduction of Universal Newborn Hearing Screening (UNHS) programs has drastically contributed to the early diagnosis of hearing loss in children, allowing prompt intervention with significant results on speech and language development in affected children. UNHS in the Lazio region has been initially deliberated in 2012; however, the program has been performed on a universal basis only from 2015. The aim of this retrospective study is to present and discuss the preliminary results of the UNHS program in the Lazio region for the year 2016, highlighting the strengths and weaknesses of the program. Methods Data from screening facilities in the Lazio region for year 2016 were retrospectively analyzed. Data for Level I centers were supplied by the Lazio regional offices; data for Level II and III centers were provided by units that participated to the study. Results During 2016, a total of 44,805 babies were born in the Lazio region. First stage screening was performed on 41,821 children in 37 different birth centers, with a coverage rate of 93.3%. Of these, 38.977 (93.2%) obtained a “pass” response; children with a “refer” result in at least one ear were 2844 (6.8%). Data from Level II facilities are incomplete due to missing reporting, one of the key issues in Lazio UNHS. Third stage evaluation was performed on 365 children in the three level III centers of the region, allowing identification of 70 children with unilateral (40%) or bilateral (60%) hearing loss, with a prevalence of 1.6/1000. Conclusions The analysis of 2016 UNHS in the Lazio region allowed identification of several strengths and weaknesses of the initial phase of the program. The strengths include a correct spread and monitoring of UNHS among Level I facilities, with an adequate coverage rate, and the proper execution of audiological monitoring and diagnosis among Level III facilities. Weakness, instead, mainly consisted in lack of an efficient and automated central process for collecting, monitoring and reporting of data and information.

Objective To investigate the hearing performance of adult patients presenting unilateral deafness with contralateral fluctuating hearing loss who received a cochlear implant on the deaf side. Study Design Case series with chart review. Setting University tertiary referral center. Subjects and Methods Preoperatively and at 6 and 12 months postoperatively, 23 patients underwent pure tone audiometry and speech audiometry with disyllabic and monosyllabic words in a quiet environment and sentences in quiet and noisy (signal-to-noise ratio +10 dB SPL) environments under best-aided conditions. The Abbreviated Profile of Hearing Aid Benefit (APHAB) inventory was evaluated preoperatively and at 6 and 12 months postoperatively. Results No difference was found between pre- and postoperative tests for disyllabic and monosyllabic words. For sentences in quiet and noisy environments, a difference between pre- and postoperative performance was present at 1 year ( P = .002 and P = .02, respectively). In a noisy environment, a difference was present at 6 and 12 months postoperatively as compared with the preoperative value (mean ± SD: 6 months: 42% ± 7.1% vs 61% ± 6.5%, P = .016). A significant improvement in the APHAB score was found at 6 and 12 months postimplantation (Friedman's 2-way analysis of variance by ranks, P < .001). The number of years of hearing deprivation of the deaf ear was not correlated with performance. Conclusion When incapacitating fluctuating hearing loss occurs in patients presenting a contralateral deaf ear, a cochlear implant is indicated in the latter ear, significantly improving performance in noisy conditions and allowing a better quality of communication to be achieved.

Questo studio riporta un’analisi retrospettica delle immagini cone beam CT effettuate su 8 pazienti adulti sottoposti ad impianto cochleare MedEl flex 28 e su 14 ossi temporali impiantati con lo stesso tipo di array portaelettrodi. Lo scopo dello studio é di determinare l’affidabilità della metodica cone beam CT nella valutazione della posizione intracocleare degli elettrodi in impianti che si posizionano lungo la parete laterale del lume cocleare, quindi non perimodiolari la cui posizione é più facilmente identificabile. Un otoradiologo e due otologi hanno analizzato le immagini e assegnato la posizione per ciascun elettrodo localizzato nella regione dei 180° e dei 360° del primo giro cocleare e per l’elettrodo apicale scegliendo tra scala timpanica, vestibulare o posizione intermedia L’analisi istologica ha successivamente confermato l’esatta posizione negli ossi temporali. Nel gruppo dei pazienti per l’elettrodo a 180° i tre esperti concordavano sulla posizione in scala timpanica in tutti eccetto un paziente, mentre una discordanza nella valutazione era presente in 3 pazienti per gli elettrodi a 360° e per gli elettrodi apicali. Negli ossi temporali in 5 casi era presente una discordanza per l’elettrodo a 180°, mentre a 360° sei valutazioni erano discordanti tra i valutatori. Una disdcordanza tra le valutazioni più elevata veniva trovata per la la posizione dell’elettrodo apicale (concordanza valutatori 45.4%, Fleiss k = 0,13). Un buon grado di concordanza veniva trovato tra i risultati istologici e le valutazioni tra i valutatori per gli elettrodi localizzati nel giro basale; un grado più basso esisteva per la posizione degli elettrodi apicali (concordanza valutatori 50%, Cohen’s k = 0,31) confermando la difficoltà nella corretta valutazione della posizione degli elettrodi nella regione più apicale negli ossi temporali. In conclusione, le immagini cone beam postoperatorie analizzate con la metodica della ricostruzione multiplanare 3D rappresentano una metodica affidabile per lo studio della posizione intracocleare degli elettrodi a posizionamento laterale nei pazienti impiantati. La corretta identificazione del posizionamento dell’elettrodo piu apicale risulta difficile su osso temporale per la presenza di un artefatto più importante o per la minore resistenza delle strutture della parete laterale della coclea (legamento spirale, membrane basilare) nel preparato istologico (osso temporale fresco/congelato) che è responsabile di un maggior numero di traslocazioni dalla rampa timpanica alla rampa vestibolare e di localizzazioni intermedie più difficilmente interpretabili.

OBJECTIVES/HYPOTHESIS To evaluate the incidence of chronic cerebrospinal venous insufficiency in Meniere's disease patients and the effect of bilateral percutaneous transluminal angioplasty of the jugular/azygos veins compared to medical therapy. STUDY DESIGN Prospective case-control study. METHODS Five hundred fourteen subjects were included in the study, 412 affected by definite Meniere's disease, and 102 healthy controls. All patients underwent audiovestibular and vascular examination. Patients with Meniere's disease and concomitant cerebrospinal venous insufficiency were divided in two subgroups: patients who underwent vascular intervention with bilateral percutaneous transluminal angioplasty (PTA) of the jugular/azygos veins and patients treated with medical therapy. RESULTS Chronic cerebrospinal venous insufficiency was diagnosed in 330/412 (80.1%) Meniere's disease patients and in 12/102 healthy individuals (11.8%) (P

Conclusion: The NiTiBOND® prosthesis allows early results to be obtained similar to those with a manually crimped prosthesis fitted by experienced surgeons, thus reducing the learning curve in this critical step of the procedure.Objective: To analyze the 1-month results using the nitinol NiTiBOND® prosthesis in primary otosclerosis surgery and to compare the results with those obtained with fully fluoroplastic or fully titanium pistons.Materials and methods: Fifty consecutive cases operated on with the NiTiBOND® prosthesis (nitinol group) were compared with 50 cases operated on with a fully fluoroplastic piston (fluoroplastic group), and with 131 cases operated on with a fully titanium piston (first titanium group), and also with 50 cases operated on with the same titanium piston just before using the NiTiBOND® piston (last titanium group). Pure-tone and speech audiometry was performed 1 month after surgery for the nitinol group. Comparison was made between the early hearing results of the four gr...

Objective To analyse the anatomical, functional and quality-of-life results when using bioactive glass in mastoid and epitympanic obliteration. Design Prospective clinical study. Setting Tertiary referral centre. Participants Forty-one cases (39 patients) operated between May 2013 and January 2015. Main outcome measures Anatomical results were evaluated by otomicroscopy 1 year after surgery and using imaging to detect residual disease. Functional results were studied by postoperative hearing gain. Quality of life was assessed with the Glasgow Benefit Inventory questionnaire and the success of surgery by a surgery-specific questionnaire. Results At 1 year, all patients presented a well-healed external auditory canal, with an intact tympanic membrane. In cases with cholesteatoma (n = 23), no recurrent retraction pockets or residual disease were observed on imaging studies. The overall air–bone gap closure was 7.7 ± 1.84 dB (mean ± se of the mean, P < 0.001, paired t-test). No significant differences were found on hearing results when comparing primary versus revision surgery, canal-wall-up versus canal-wall-down obliterations, type of tympanoplasty and presence of cholesteatoma (multifactor anova). The Glasgow Benefit Inventory improved with an average score of 28 and the success of surgery questionnaire showed a significant improvement in ear discharge and a moderate improvement in hearing and equilibrium. Conclusions The use of bioactive glass for mastoid and epitympanic obliteration in canal-wall-down or canal-wall-up tympanoplasties is an effective procedure in both primary and revision surgery. The anatomical and functional results appear to be well correlated with patient experience and to the improvement in quality of life.

Objective To evaluate the efficacy of portable Meniett low-pressure pulse generator (Medtronic Xomed, Jacksonville, FL) in Meniere disease. Study Design Randomized, double-blind, placebo-controlled, multicenter trial carried out in 17 academic medical centers. Methods One hundred twenty-nine adults presenting Meniere disease (American Academy of Otolaryngology–Head and Neck Surgery criteria) not controlled by conventional medical treatment were included. The protocol included three phases: 1) placement of a transtympanic tube and evaluation of its effect (if resolution of symptoms, the patient was excluded); 2) randomization: 6-weeks treatment with Meniett (Medtronic Xomed) or placebo device; 3) removal of the device and 6-week follow-up period. The evaluation criteria were the number of vertigo episodes (at least 20 minutes with a 12-hour free interval) and the impact on daily life as assessed by self-questionnaires. Results Ninety-seven patients passed to the second phase of the study: 49 and 48 patients received the Meniett (Medtronic Xomed) or the placebo device, respectively. In the placebo group, the number of vertigo episodes decreased from 4.3 ± 0.6 (mean ± standard error of the mean) during the first phase to 2.6 ± 0.5 after 6 weeks of treatment, and to 1.8 ± 0.8 after the removal of the device. Similar results were observed in the Meniett device (Medtronic Xomed) group: 3.2 ± 0.4 episodes during the first phase, 2.5 ± after 6 weeks of Meniett device (Medtronic Xomed) treatment, and 1.5 ± 0.2 after the third phase. Conclusion An improvement of symptoms was evidenced in all patients, with no difference between the Meniett (Medtronic Xomed) and the placebo device groups. The decrease in the number of vertigo episodes could be explained by an effect of the medical care. Level of Evidence 1b. Laryngoscope, 2016 127:470–475, 2017

International audience; Objective: Facial nerve tumors are rare lesions mostly located in the geniculate ganglion. This study aims to compare those tumors limited to the geniculate ganglion in terms of clinical features and postoperative outcomes.Study design: Case series with chart review.Settings: University tertiary reference center.Subjects and Methods: Medical charts were reviewed for 17 patients who had surgery for geniculate ganglion tumor removal (10 hemangiomas, 6 schwannomas, 1 meningioma). Hemangiomas and schwannomas were compared for preoperative facial nerve function, hearing, tumor size, and postoperative outcomes.Results: Facial palsy was observed in all cases. Regarding the preoperative facial nerve function, severe facial palsy (House-Brackmann grades V and VI) was present in 70% of cases for hemangiomas and for no case of schwannoma (P = .01), although hemangiomas were significantly smaller tumors (P = .01). Hearing loss was observed in 4 cases (23.5%) and was related to tumor volume (P < .0001). A complete excision was achieved in all cases, and a facial nerve graft was performed immediately after interruption in 16 patients (94%). Postoperative facial nerve function was improved or stabilized in 94% of cases. A preoperative House-Brackman grade VI was shown as a negative factor for postoperative facial nerve function.Conclusions: Differences in clinical presentations could help in establishing the good therapeutic option depending on the tumor type. Surgery, when indicated, is safe and effective, and postoperative outcomes are not related to tumor type.

International audience; Surgical management of cholesteatoma limited to the attic and/or mesotympanum remains controversial. The aim of this study is to evaluate the anatomical and the functional results of trans-canal atticotomy in this pathological condition. The records of 27 adult patients treated from 2008 to 2014 who underwent trans-canal atticotomy for primary cholesteatoma surgery were reviewed. Pre-operative physical examination, audiometry, and CT-scan have been analyzed. Intraoperative findings have been described as well as the surgical technique. Anatomical and functional results have been evaluated with a mean follow-up of 24 ± 12.2 months, and the results of a CT-scan performed 1 year after surgery were examined to assess the presence of residual disease. Surgeries were uneventful. During the follow-up, 1 patient (4 %) experienced a retraction of the attical reconstruction; all the other patients had a well-healed tympanic drum with stable attical reconstruction. The mean air-bone gap was 19 ± 12.2 and 10 ± 7.3 dB pre-operatively and post-operatively, respectively (mean ± SD, p = 0.001, paired t test). Twenty-two patients (81 %) had no opacity suggesting residual cholesteatoma in CT-scan. Four patients (15 %) presenting an opacity at CT-scan underwent MRI study that was negative for residual cholesteatoma. One patient (4 %) had displacement of the ossicular prosthesis. In conclusion, cholesteatomas restricted to the attic and/or mesotympanum can be removed in a one-stage technique with no visible residual at 1 year, and with closure of the air-bone gap by 50 %.

The role of the immune system in mediating cochleovestibular pathologies has received increasing attention in recent years. Autoimmune vertigo may be an invalidating condition and may worsen the quality of life of affected patients, especially in the cases of delayed diagnosis. Since the etiopathogenesis is still not clear, also the treatment is not yet completely delineated. According to the clinical presentation, autoimmune vertigo can present as an isolated disorder or in association with systemic autoimmune diseases. The main feature in autoimmune vertigo is the presence of an abnormal immune response, in either absence or presence of systemic autoimmune disease, directed against delicate components of the inner ear. This may determine a functional or anatomical alteration, with an inflammatory reaction often devastating for hearing and balance. Being the exact pathogenesis unknown, the diagnosis of autoimmune vertigo is based either on clinical criteria or on a positive response to steroids. The earlier the diagnosis is made, the sooner the therapy can be installed, giving a chance to the recovery of inner ear damages. Corticosteroids represent the most effective and universally accepted treatment, even if other immunomodulatory drugs are now having a more extensive use. HIGHLIGHTS: Vertigo is relatively frequent in autoimmune diseases; however, it is often misdiagnosed or attributed to central nervous system alterations rather to specific inner ear involvement. Vertigo and other audiovestibular symptoms may be the first manifestation of an autoimmune disease and if correctly addressed could significantly contribute to early diagnosis of the underlying autoimmune disease. Early diagnosis of immune-related vertigo can lead to prompt initiation of targeted therapy with elevate chances of preventing irreversible damages to the inner ear. The presence of alternating phases of well-being and disabling symptoms in patients with vertigo should always been considered, as they could suggest an underlying autoimmune condition.

Many symptoms of multiple sclerosis may affect the ear, nose and throat. The most common otolaryngologic symptoms of multiple sclerosis are speech disorders, followed by sleep disorders, vertigo and disequilibrium, dysphagia, smell alterations, and hearing loss. Less common symptoms include sialorrhea, facial palsy, taste alterations, trigeminal neuralgia and tinnitus. The origin of otolaryngologic symptoms in multiple sclerosis is mainly central, although increasing evidence also suggests a peripheral involvement. Otolaryngologic symptoms in multiple sclerosis may have different clinical presentations; they can appear in different stages of the pathology, in some cases they can be the presenting symptoms and their worsening may be correlated with reactivation of the disease. Many of these symptoms significantly affect the quality of life or patients and lead to increased morbidity and mortality. Otolaryngologic symptoms are common in multiple sclerosis; however, they are often overlooked. In many cases, they follow the relapsing-remitting phases of the disease, and may spontaneously disappear, leading to a delay in multiple sclerosis diagnosis. Clinicians should be aware of otolaryngologic symptoms of multiple sclerosis, especially when they are associated to neurologic symptoms, as they may be early signs of a still undiagnosed multiple sclerosis or could help monitor disease progression in already diagnosed patients.

The present study aims to obtain a probability model allowing prediction of auditory recovery in patients affected by sudden sensorineural hearing loss treated exclusively with intratympanic steroids. A monocentric retrospective chart review of 381 patients has been performed. A Probit model was used to investigate the correlation between the success of treatment (marked or total recovery according to Furuashi's criteria) and the delay between onset of disease and beginning of therapy. The age of patients and audiometric curve shapes were included in the analysis. The results show that delay is negatively correlated with variable success. Considering the entire sample, each day of delay decreases the probability of success by 3%. The prediction model shows that for each day that passes from the onset of the disease the probability of success declines in absence of the medical treatment, hence we conclude that early treatment is strongly recommended.Previsione delle possibilità di recupero uditivo nell’ipoacusia improvvisa trattata con steroidi intratimpanici.Il presente studio ha lo scopo di ottenere un modello di probabilità che consenta di prevedere il recupero uditivo nei pazienti affetti da ipoacusia improvvisa neurosensoriale trattati esclusivamente con steroidi intratimpanici. È stata realizzata una revisione retrospettica dei dati di 381 pazienti. Un modello Probit è stato utilizzato per studiare la correlazione tra il successo del trattamento (“marked” or “total recovery” secondo i criteri di Furuashi) e il ritardo (Delay) tra l’insorgenza della malattia e l’inizio della terapia. Sono stati inclusi nell’analisi i dati relativi all’età dei pazienti e alle curve audiometriche. Dallo studio è emerso che la variabile Delay è negativamente correlata con la variabile successo. Considerando l’intero campione, ogni giorno di ritardo diminuisce del 3% la probabilità di successo. Il modello di previsione mostra che per ogni giorno che passa dal momento della comparsa della malattia, la probabilità di successo declina in assenza dell’intervento; possiamo quindi concludere che il trattamento precoce è fortemente raccomandato.

OBJECTIVES/HYPOTHESIS To evaluate the influence of the diameter of stapes prosthesis on functional outcomes in stapes surgery. STUDY DESIGN Prospective cohort study. METHODS Fifty consecutive small fenestra stapedotomies performed using a 0.4-mm-diameter prosthesis were compared with 50 consecutive small fenestra stapedotomies carried out using a 0.6-mm-diameter piston. Audiological assessment following the recommendations of the Committee on Hearing and Equilibrium was performed 1 month after surgery. Postoperative complications between the two groups were noted. RESULTS There were no statistically significant differences in demographic data between the two groups, and no differences in preoperative bone-conduction (BC) or air-conduction (AC) hearing thresholds for all frequencies (analysis of variance [ANOVA] and χ2 tests). No differences were found in the mean preoperative BC and AC pure-tone average and air-bone gap (ABG). In the postoperative evaluation, a statistically significant difference was found for the mean AC gain (20 ± 8.7 vs. 24 ± 11.5, P = .042, ANOVA) as well as for the postoperative AC threshold at 0.125 and 0.25 kHz and the postoperative BC threshold at 0.25 kHz (P < .01, ANOVA). A postoperative ABG ≤10 dB was obtained in 90% and 94% of patients in the 0.4-mm- and 0.6-mm-diameter piston groups, respectively (difference not significant, χ2 test). No postoperative dead ear and/or sensorineural hearing loss was noted in either group. CONCLUSIONS The 0.6-mm piston allowed a statistically significant higher AC gain compared with the 0.4-mm diameter piston. A larger diameter piston may be preferable if there are no anatomical or technical reasons that would favor a smaller prosthesis. LEVEL OF EVIDENCE 2b Laryngoscope, 1922-1926, 2018.

International audience; Cochlear implant insertion should be as least traumatic as possible in order to reduce trauma to the cochlear sensory structures. The force applied to the cochlea during array insertion should be controlled to limit insertion-related damage. The relationship between insertion force and histological traumatism remains to be demonstrated. Twelve freshly frozen cadaveric temporal bones were implanted with a long straight electrodes array through an anterior extended round window insertion using a motorized insertion tool with real-time measurement of the insertion force. Anatomical parameters, measured on a pre-implantation cone beam CT scan, position of the array and force metrics were correlated with post-implantation scanning electron microscopy images and histological damage assessment. An atraumatic insertion occurred in six cochleae, a translocation in five cochleae and a basilar membrane rupture in one cochlea. The translocation always occurred in the 150-to 180-degree region. In the case of traumatic insertion, different force profiles were observed with a more irregular curve arising from the presence of an early peak force (30 ± 18.2 mN). This corresponded approximately to the first point of contact of the array with the lateral wall of the cochlea. Atraumatic and traumatic insertions had significantly different force values at the same depth of insertion (p < 0.001, two-way ANOVA), and significantly different regression lines (y ¼ 1.34x þ 0.7 for atraumatic and y ¼ 3.37x þ 0.84 for traumatic insertion, p < 0.001, ANCOVA). In the present study, the insertion force was correlated with the intracochlear trauma. The 150-to 180-degree region represented the area at risk for scalar translocation for this straight electrodes array. Insertion force curves with different sets of values were identified for traumatic and atraumatic insertions; these values should be considered during motorized insertion of an implant so as to be able to modify the insertion parameters (e.g axis of insertion) and facilitate preservation of endocochlear structures.

OBJECTIVES The aim of the study was to evaluate the sleep architecture and its possible alterations in chronic tinnitus patients, and investigate any possible correlation between sleep architecture modifications and tinnitus perception, adaptation, and the degree of discomfort in these patients. DESIGN In a prospective, case-control, nonrandomized study, 18 patients affected by chronic tinnitus were compared with a homogeneous control group consisting of 15 healthy subjects. The experimental group was enrolled at the Tinnitus ambulatory at Policlinico Umberto I Department of Sensory Organs, and the control group was composed of voluntary subjects. A full overnight polysomnography was performed on both groups. Tinnitus patients answered two questionnaires: the tinnitus handicap inventory (THI) and a questionnaire concerning their subjective sleep quality, tinnitus intensity before bedtime, tinnitus intensity at remembered nocturnal wake-up periods, and tinnitus intensity at morning wake-up. Controls completed only the sleep quality questionnaire. RESULTS All tinnitus patients had a statistically significant alteration in sleep stages. Average percentage of stage 1 + stage 2 was 85.4% ± 6.3, whereas, in the control group, the average percentage of stage 1 + stage 2 was 54.9 ± 11.2 (p < 0.001). Stages 3 and 4 and rapid eye movement (REM) sleep was lacking in all tinnitus patients with an average percentage of 6.4 ± 4.9 of REM sleep, and 6.4 ± 4.9 of stages 3 + 4. The control group showed an average percentage of 21.5 ± 3.6 of REM sleep and 21.5 ± 3.6 of stages 3 + 4 (p < 0.001). No correlation was found between the decrease of REM and the increase of the THI score in the tinnitus group (r = 0.04). However, a mild correlation was found between the increase of light sleep (stage 1 + stage 2) and the THI score reported by the tinnitus group. Therefore, patients with light sleep report a higher THI score (r = 0.4). CONCLUSIONS The significant alteration of sleep parameters assessed in tinnitus patients underlines the necessity to consider an adequate therapy that could improve patients' sleep quality and also opens avenues for further investigations.

Objectives/Hypothesis: To investigate the efficacy of an intratympanic steroid as a first-line therapy in patients affected by moderate idiopathic sudden sensorineural hearing loss (ISSNHL). Study Design: Prospective, randomized, triple-blind, placebo-controlled trial. Methods: Fifty patients presenting with moderate idiopathic sudden sensorineural hearing loss involving all frequencies from 250 Hz to 8,000 Hz (a flat audiogram) were enrolled. Patients were randomized into two groups of 25 each. The first group (intratympanic steroid) underwent a daily intratympanic administration of prednisolone for 3 consecutive days. Subjects in the second group (control) received a daily intratympanic injection of a saline solution for 3 consecutive days. Audiometric tests were performed at day 7 after the beginning of therapy (T1), and then 10 and 30 days after T1. The patients in both groups who did not show a complete recovery at T1 were treated with oral prednisone at a tapering dose. Results: In the intratympanic steroid group, 19 out of 25 patients presented at T1 complete recovery (76%), whereas in the control group the number patients who recovered completely at T1 was five out of 25 (20%). The mean pure-tone average (PTA) recorded at T1 shows a statistically significant improvement in the hearing threshold of the first group compared to the control group (P < .01). Conclusions: The mean PTA recorded after the first-line approach (T1) demonstrated a significant therapeutic action of the short-duration intratympanic steroid therapy on moderate ISSNHL, with a flat audiogram shape, compared to the natural course of the disease and the placebo effect at that time point.

International audience; Cholesterol granulomas represent 40% of benign lesions developed within the petrous apex.Most of them areasymptomatic and do not require any treatment.When they involve adjacent structures such as the inner ear, the inter nal auditory meatus, the cranial nerves, or when they are painful, surgical management is required although this is challenging because of the position of the lesion and the high rate of recurrence.

International audience; Single-sided deafness (SSD) represents one of the most difficult audiological conditions to rehabilitate. The aim of this prospective study was to evaluate the audiological benefits and quality of life of patients affected by SSD who had previously been users of the Alpha 1® when upgrading them to the Sophono Alpha 2® external processor (Boulder, Colo., USA). Nine patients were included in the study. They underwent physical examination, free-field speech audiometry at 40 and 60 dB, a hearing-in-noise test (Hirsch's test and the squelch test), the Glasgow Benefit Inventory (GBI) questionnaire, and a specific questionnaire on patient satisfaction with Alpha 1. Afterwards, the Alpha 2 external processor was delivered to all patients, and the above-mentioned protocol was repeated after 1 month with the Alpha 2. A statistically significant improvement was found in the speech discrimination score at 40 dB and in the squelch test when using the Alpha 2 external processor compared to the Alpha 1. Alpha 2 had a good clinical tolerance and gave similar results in the specific questionnaire and the GBI to Alpha 1. In conclusion, the new Alpha 2 external processor represents a safe and effective device for the rehabilitation of SSD, and there is an audiological benefit to upgrading to the Alpha 2 external processor for patients who had previously been users of the Alpha 1. The improvement in quality of life is similar to that with other bone-anchored hearing devices.

Objective. To evaluate the cutaneous and the inner ear tolerance of bioactive glass S53P4 when used in the mastoid and epitympanic obliteration for chronic otitis surgery.Material and Methods. Forty-one cases have been included in this prospective study. Cutaneous tolerance was clinically evaluated 1 week, 1 month, and 3 months after surgery with a physical examination of the retroauricular and external auditory canal (EAC) skin and the presence of otalgia; the inner ear tolerance was assessed by bone-conduction hearing threshold 1 day after surgery and by the presence of vertigo or imbalance.Results. All surgeries but 1 were uneventful: all patients maintained the preoperative bone-conduction hearing threshold except for one case in which the round window membrane was opened during the dissection of the cholesteatoma in the hypotympanum and this led to a dead ear. No dizziness or vertigo was reported. Three months after surgery, healing was achieved in all cases with a healthy painless skin. No cases of revision surgery for removal of the granules occurred in this study.Conclusion. The bioactive glass S53P4 is a well-tolerated biomaterial for primary or revision chronic otitis surgery, as shown by the local skin reaction which lasted less than 3 months and by the absence of labyrinthine complications.

International audience; Facial nerve schwannoma is the most common facial nerve tumor, but its therapeutic strategy remains debated. The aim of this study is to analyze the facial nerve function and the hearing outcomes after surgery or wait-and-scan policy in a facial nerve schwannoma series. A monocentric retrospective review of medical charts of patients followed for an intratemporal facial nerve schwannoma between 1988 and 2013 was performed. Twenty-two patients were included. Data were extracted pertaining to the following variables: patient demographics, tumor localization, clinical and imaging features, facial nerve function and hearing levels, and details of surgical intervention. The majority of tumors were located at the geniculate ganglion. Initial symptoms were mainly facial palsy and hearing loss. The average follow-up was 4.8 ± 4.5 years. Nineteen patients underwent surgery, and three patients were observed. After surgery, 11 patients had a stable or improved facial nerve function (57.9 %), and 8 patients had a worsened facial nerve function (42.1 %). Facial nerve function was in the majority of cases a HB grade III, depending on surgical strategy. No patient presented a postoperative HB grade V or VI. Regarding the hearing, it remained stable after surgery in 52.6 % of cases, and improved in 10.5 % of cases. Among monitored patients, facial nerve function and hearing remained stable. Surgery for facial nerve schwannoma is a safe and effective option in the treatment of these tumors.

The present study was designed to verify the correlation between tinnitus and temporomandibular joint dysfunction.86 consecutive patients were enrolled in the study, all affected by subjective tinnitus without hearing impairment, from both genders, age between 18 and 60 years old. The final number of patients included in the study was 55. All patients received a temporo-mandibular joint examination. All the patients were asked to rate the severity of their symptoms before and after treatment using a VAS scale and the Tinnitus Handicap Inventory (THI) and they followed a standardized protocol for the investigation of tinnitus. All the subjects were monitored by the same researcher and they underwent the same splint treatment. The comparison between pre- and posttreatment phase scores showed in patients with predisposition of TMD and with TMD a statistically significant decrease of THI and VAS values. The characteristics of tinnitus and the degree of response to treatment confirmed the relationship between tinnitus and TMD. The authors believe that, when the most common causes of tinnitus, such as otologic disorders and neurological diseases are excluded, it is correct to evaluate the functionality of the temporo-mandibular joint and eventually treat its pathology to obtain tinnitus improvement or even resolution.

Objectives: To assess the therapeutic effectiveness of an intratympanic (IT) steroid protocol compared to a systemic steroid protocol. Methods: A total of 265 consecutive patients presenting unilateral idiopathic sudden sensorineural hearing loss were divided into 2 groups. One group comprised 131 patients enrolled between May 2009 and May 2010, and the other consisted of 134 patients enrolled between June 2010 and June 2011; a total of 48 patients were excluded among the 2 groups. The first group received oral prednisone for 8 days in tapering doses; the second group had IT prednisolone at a dose of 62.5 mg/ml once a day for 3 consecutive days. Audiological examinations were performed at study entry and 30 days after the beginning of therapy. Mean pure tone audiometry (PTA) of both groups and hearing outcomes following the criteria of Furuhashi et al. [Clin Otolaryngol 2002;27:458-463] and Siegel [Otolaryngol Clin North Am 1975;8:467-473] were investigated. Results: The strong efficacy of steroid therapy was evident in both groups, observing both PTA and hearing threshold improvement. The evaluation of the hearing outcomes shows a significantly better result for the short-term IT protocol; this result is ascribable to two types of audiometric curves: down- and up-sloping. Conclusion: The results show a significant efficacy of both steroid therapeutic approaches. There was no significant difference in PTA improvement between the 2 study groups; the short-term IT protocol led to better results in the evaluation of the hearing outcomes (following the criteria of Siegel and Furuhashi et al.) for up- and down-sloping audiometric curves.

In Italy, a West Nile virus (WNV) surveillance plan was firstly implemented in 2008 and 2009 in two affected regions and, since 2010, according to a national plan, a WNV neuroinvasive disease (WNND) surveillance has to be carried out each year during the period 15 June–30 November, in those regions where WNV circulation has been demonstrated among humans, animals or vectors. Moreover, since WNV can be transmitted to humans even by blood transfusions and organ transplants obtained from infected donors, the national surveillance integrates the blood transfusions and organs transplant surveillances too. The paper describes the results of this integrated human surveillance in Italy in 2012. Overall, in 2012, 28 autochthonous confirmed cases of WNND were reported, 14 blood donations were found WNV positive by Nucleic Acid Amplification Test and no solid organ donors tested positive for WNV. Moreover, 17 cases of WNV fever were confirmed in Veneto region. When comparing the number of WNND cases reported to the surveillance system in previous 4 years (43 cases during the period 2008–2011), with those reported in 2012 an important increase was observed in 2012. The geographic distribution of human cases was consistent with the WNV circulation among animals and vectors. Moreover, the implementation of preventive measures for WNV transmission through blood components allowed the detection of blood donors positive for WNV, avoiding the further spread of the disease. Since surveillance strategies and preventive measures are based on the integration among human, animal and vector control activities, the Italian experience could be considered a good example of collaboration among different sectors of public health in a “one health” perspective.

Rhinophyma, the advanced stage of rosacea, is a lesion characterized by progressive hypertrophy and hyperplasia of sebaceous glandular tissue, connective tissue, and blood vessels. Rhinophyma can lead to a significant facial disfigurement and severe emotional distress, but it is not only an aesthetic problem, since rare cases of simultaneous presence of malignant tissue are described in the literature. The case of an 84-year-old farmer affected by basal cell carcinoma (BCC) and diagnosed in the context of rhinophyma is presented. The anatomical distortion produced by the chronic inflammation and fibrous scarring makes the BCC diagnosis difficult and uncertain. The histological examination of the entire mass and its margins is fundamental. A partial biopsy can lead to a false negative result, and the histological examination must be repeated intra- or postoperatively.

The results demonstrate the stability of the efficacy over time of the intratympanic prednisolone protocol and they suggest that the spontaneous recovery does not significantly influence the long-term evaluation of intratympanic therapy. A 10-day follow-up after 3 days of intratympanic prednisolone administration can be considered a sufficient period to evaluate the effectiveness of the undertaken therapy.To assess the stability of the efficacy over time of intratympanic steroid therapy for patients with idiopathic sudden sensorineural hearing loss.A total of 122 patients received an intratympanic steroid injection of prednisolone daily for 3 days. Audiograms were performed before therapy and at 10 days and 1 year after therapy. Successful recovery was defined as complete and partial recovery using Siegel's criteria and complete and marked recovery following Furuhashi's criteria.The comparison of audiometric data at study entry, at 10 days, and at 1 year after the treatment showed a statistically significant improvement of the mean pure tone audiometry. The evaluation of the hearing outcomes demonstrated a statistically significant improvement, with similar success rates when evaluated 10 days and 1 year after the treatment. Comparing the hearing outcomes at 1 year with the results at 10 days, no significant difference was detected between these two time points.

The excellent tolerability of intratympanic (IT) steroid offers the possibility to use a high dose, which would appear to be more effective than intravenous (IV) steroid treatment, when both are associated with hyperbaric oxygen (HBO) therapy.The purpose of the study was to assess for the first time the efficacy of the association of IT steroid and HBO therapy in patients presenting idiopathic sudden sensorineural hearing loss (ISSNHL), comparing this protocol with another consisting of IV steroid administration and HBO therapy.A total of 48 patients presenting ISSNHL were recruited. Patients were divided into two categories: the severe ISSNHL group with a pure-tone average (PTA) between 70 and 90 dB, and the profound ISSNHL group with a PTA90 dB. The first protocol consisted of 10 days of HBO therapy together with IV methylprednisolone 1 mg/kg body weight for 7 days; the second protocol consisted of HBO therapy for 10 days, associated with an IT injection of prednisolone at a dose of 62.5 mg/ml, once a day for 3 consecutive days, performed 2 h before the HBO therapy.The overall success rate was superior in the group submitted to IT steroid and HBO therapy. Nevertheless, these clinical results were not statistically significant.

The amount of copies of HCV-RNA and count of CD8(+) lymphocytes was retrospectively evaluated in 326 patients: sampling was performed in basal condition, during treatment with alpha-IFN (n=232) and post-treatment follow-up, and at the same time points in untreated patients (n=94). In the treated group the difference between CD8(+) lymphocytes in the patients successfully treated (n=65) and those with an unfavourable outcome (n=176) is statistically significant (898+/-172 vs., 440+/-176 CD8(+) lymphocytes per mm(3) P0.005 ANOVA). Also, in the untreated patients the average count of CD8(+) cells is statistically higher in patients with a favourable outcome (P0.01 ANOVA). The present data show that the count of CD8(+) lymphocyte is of clinical value in order to predict the outcome of HCV infection and may be used together with the viral load and genotype, already established predictors.
