Vestibular migraine (VM) is one of the most frequent causes of episodic vertigo, with a lifetime prevalence of 0.98%. Prophylactic therapy includes calcium channel blockers, beta-blockers, antiepileptic drugs and antidepressants. We studied the association of cinnarizine 20 mg and dimenhydrinate 40 mg (Arlevertan) in a group of 22 patients affected by definite VM. Proposed therapy included one tablet twice a day for 1 month, which was repeated three times with 1 month of interval between drug intake; results were compared with those of a control group of 11 VM patients who asked to observe only lifestyle measures for migraine. The main outcome was the number of vertigo and headache crises in the 6 months before therapy and in the 6 months of follow-up. Subjects performing Arlevertan presented during the 6 months of therapy a decrease of vertigo attacks from 5.3 to 2.1 and of headaches from 4.3 to 1.7 (p < 0.0001); 68% of these subjects reported a decrease of at least 50% of vertigo attacks, while 63% of headaches. Conversely, vertigo attacks decreased from 3.5 to 2.2 and headaches from 2.6 to 2 in patients observing only lifestyle; 18% of these subjects reported a decrease of at least 50% of vertigo crises and 27% of headaches. Our data do not differ from those of previous works assessing efficacy of different prophylactic therapies for VM and reporting consistent reduction of vertigo spells in a rate of patients ranging from 60 and 80%.

Metastases to parapharyngeal or retropharyngeal lymph nodes are rare in well-differentiated thyroid cancers. A review of English literature found only 112 cases reported in the last two decades, with an incidence of parapharyngeal lymph nodes metastases ranging from 0.43 to 2.5%. Surgical resection is the most effective treatment for patients with parapharyngeal lymph node metastasis from thyroid carcinoma. We describe two cases of thyroid cancer parapharyngeal lymph node metastases that were surgically removed using a traditional transcervical approach, with the help of a minimally-invasive video-assisted technique. A video-assisted minimally-invasive transcervical approach is a new technique for excision of sizable benign tumours and selected malignant tumours. The endoscopic technique allows clear identification of critical surgical landmarks that guide the dissection through the correct cleavage plane in a nearly bloodless surgical field, thus decreasing the rate of complications. In both patients postoperative follow-up showed no sequelae and recurrence after 20 and 15 months from surgery.

Obstructive sleep apnea is a well-known clinical manifestation of Prader-Willi syndrome. The aim of our study is to evaluate the efficacy of adenotonsillectomy for the treatment of the disorder as well as the improvement of their post-operative quality of life. Five patients with moderate to severe obstructive sleep apneas and adenotonsillar hypertrophy of grade III-IV underwent adenotonsillectomy. Pre- and postoperative apneas and Quality of Life were assessed respectively with a polysomnography with multi-sleep latency test and with the pediatric Quality of Life questionnaire, performed before and 6 months after surgery. A decrease of apnea/hypopnea index values has been detected between pre- and post-surgery (t=2.64, P=0.005), as well as oxygen desaturation index values (t=5.51, P=0.005), multi-sleep latency test (t=4.54, P=0.01), and of the values of pediatric Quality of Life questionnaire. No correlation has been detected between body mass index and apnea/hypopnea index, oxygen desaturation index and multi-sleep latency test values pre- and post-adenotonsillectomy. A correlation has been found between multi-sleep latency test and oxygen desaturation index values post-surgery (P=0.04). No post-operative complications were observed. Our data underline the efficacy of surgery in Prader-Willi patients with adenotonsillar hypertrophy in order to improve their quality of life.

Background: The aetiopathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) is still unknown. The role of atopy and the concept of united airways in such patients are still a matter of debate. In this pilot study we aimed at evaluating the degree of eosinophilic inflammation and the frequency of atopy in a cohort of CRSwNP patients candidate for Functional Endoscopic Sinus Surgery (FESS) and assessing the association between these factors and relapsing forms of CRSwNP., Methods: 30 patients (18 men, 12 women) with CRSwNP eligible for FESS were evaluated before and after surgery. Preoperative investigation included: history of previous relapse after FESS, clinical and laboratory allergologic assessment, spirometry, methacholine challenge, blood eosinophilia and determination of the fraction of nitric oxide in exhaled air (FeNO). Nasal fibroendoscopy, spirometry and FeNO determination were also assessed prospectively at 3 and 27 months post-FESS., Results: 18/30 subjects were atopic, 6/18 (33 %) were monosensitized, 16/30 (53 %) were asthmatics and 10/30 (33 %) had non steroidalantinflammatory drugs (NSAIDs) hypersensitivity. Twenty-one patients (70 %) were classified as relapsers, 15/18 (83 %) among atopics, 6/12 (50 %) among non atopics (p = 0.05). Among patients with NSAIDs hypersensitivity, 9/10 (90 %) were relapsers. The median IgE concentration was 161.5 UI/mL in relapsers and 79 UI/mL in non-relapsers (ns). The mean FeNO decreased after FESS (43.1-26.6 ppb) in 84 % of patients, but this effect disappeared over time (FeNO = 37.7 ppb at 27 months). Higher levels of FeNO pre-FESS were detected in atopics, and in particular in relapsing ones (median 51.1 ppb vs 22.1, ns). Higher levels of FeNO pre-FESS were detected in asthmatic patients, especially in those who relapsed (median: 67 vs 64.85 ppb in non-relapsed patients, ns). The Tiffeneau Index (FEV1/FVC) was significantly lower in asthmatic relapsers than in non relapsers asthmatics (94.7 ± 11.1 versus 105 ± 5.9-p = 0.04). Patients with asthma and atopy had a major risk of relapse (p = 0.05)., Conclusion: In our pilot study, atopy, severe asthma, bronchial inflammation, NSAIDs hypersensitivity and high level of total IgE are possible useful prognostic factors for the proneness to relapse after FESS. The role of allergy in CRSwNP pathogenesis should consequently be given deeper consideration. Allergen specific immunotherapy, combined with anti-IgE therapy, may have an immunomodulatory effect preventing polyps relapse and need to be investigated.

Cancer of the larynx in the intermediate/advanced stage still presents a major challenge in terms of controlling the disease and preserving the organ. Supratracheal partial laryngectomy (STPL) has been described as a function-sparing surgical procedure for laryngeal cancer with sub-glottic extension. The aim of the present multi-institutional study was to focus on the indications and contraindications, both local and general, for this type of surgery based on the long-term oncological and functional results. We analysed the clinical outcomes of 142 patients with laryngeal cancer staged pT2-pT4a who underwent STPL. Five-year overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS) and loco-regional control (LRC) rates were: glottic pT2 [71.4%, 95.2%, 76.0%, 76.0%], glottic-transglottic pT3 [85.3%, 91.1%, 86.4%, 88.7%], and pT4a [73.2%, 88.1%, 52.7%, 60.7%], respectively. DFS and LRC prevalences at 5 years were greatly affected by pT4a staging. Five-year laryngeal function preservation (LFP) and laryngectomy free survival (LFS) were: glottic pT2 [90.9%, 95.2%], glottic-transglottic pT3 [84.4%, 93.1%], and pT4a [63.7%, 75.5%], respectively, being affected by pT staging and age 65 ≥ years (LFP 54.1%). As a result of Type III open horizontal partial laryngectomies (OPHLs) (supratracheal laryngectomies), the typical subsites of local failure inside the larynx were the mucosa at the passage between the remnant larynx and trachea, the mucosa at the level of the posterior commissure and the contralateral cricoarytenoid unit as well as outside the larynx at the level of the outer surface of the remnant larynx. For patients with glottic or transglottic tumours and with sub-glottic extension, the choice of STPL can be considered to be effective, not only in prognostic terms, but also in terms of functional results.

Background: Narrow band imaging (NBI) endoscopy is a technique that allows for real-time visualization of mucosal and submucosal vascular patterns., Objective: Because granulomatosis with polyangiitis (GPA) (Wegener granulomatosis) is an autoimmune disease defined by vascular inflammation, we examined patients with GPA and with NBI to evaluate whether disease-specific mucosal vascular patterns were present. To the best of our knowledge, the use of NBI endoscopy for assessment of an immune system disease such as GPA has never been previously attempted., Methods: We conducted a prospective observational study by performing an endoscopic evaluation of upper airways with NBI on patients diagnosed with GPA; on patients with symptoms and signs suggestive for GPA, who were scheduled to undergo nasal biopsy to confirm diagnosis; on patients affected by chronic rhinosinusitis with nasal polyps; and on healthy controls., Results: We enrolled 69 patients. NBI vascular patterns in patients with GPA were consistently and recognizably different from healthy mucosal patterns in 53% of our cases. In patients with GPA, biopsy and NBI results were for the most part comparable, except for three cases., Conclusion: Nasal mucosa NBI endoscopy can be considered a promising rapid and noninvasive live imaging technique for nasal mucosa GPA that, based on further study, could become a supplementary diagnostic tool in the complex workup of GPA and vasculitis.

Objectives: Meniere's disease (MD) is an inner ear disorder characterized by episodic vertigo, ear fullness, and hearing loss; usually vertigo attacks cluster in specific period. We studied in MD patients the circulating levels of chromogranin A (CgA) and vasostatin-1 (VS-1), secreted by the neuroendocrine system and involved in the regulation of the endothelial barrier function., Methods: Serum levels were assessed in 37 MD patients and 36 controls. The ratio between VS-1 and CgA was calculated., Results: CgA was increased in patients compared to controls (1.46 versus 0.67 nM, p = 0.01) while no difference was detected for VS-1 (0.41 versus 0.39, resp.). CgA levels in patients positively correlated with the frequency of vertigo spells in the previous four weeks (p = 0.008) and negatively with the time in days from the last vertigo attack (p = 0.018). Furthermore, the VS-1/CgA ratio negatively correlated with the frequency of vertigo spells (p = 0.029) and positively correlated with the time from the last attack (p = 0.003)., Conclusion: The results indicate that variations of CgA levels, but not of VS-1, occur in the blood of patients with active MD, depending on the frequency of vertigo spells and the time from the last crisis.

Previous reports focusing on the high prevalence of voice disorders in teachers have suggested that vocal loading might be the main causal factor. The aim of our study was to assess the prevalence of voice disorders in a sample of primary school teachers and evaluate possible cofactors. Our sample was composed of 157 teachers (155 females, mean age 46 years). Participants were asked to complete two selfadministrated questionnaires: one with clinical data, and the second an Italian validated translation of VHI (voice handicap index). On the same day they also underwent a laryngostroboscopic exam and logopedic evaluation. The results were compared with those of a control group composed of accompanying individuals. Teachers presented a higher rate of abnormalities at laryngostroboscopic examination than the control group (51.6% vs. 16%, respectively). Among these, 7.1% presented nodules. In our sample, vocal fold disorders were not correlated with years of teaching, smoking, coffee consumption, or levels of anxiety. Our findings are in agreement with previous reports on the prevalence of pathologic disorders among teachers; nonetheless, the prevalence of nodules was lower than in previous investigations, and voice loading was not correlated with laryngostroboscopic findings. Current Italian law does not include any guidance regarding voice education and screening in subjects with high vocal loading. Our work stresses the need for such legislation.

Prophylactic therapy of Ménière's disease (MD) includes betahistine and calcium-blockers (the latter also useful for migraine prevention). The aim of our work was to assess the efficacy of combined therapy with cinnarizine and betahistine in MD subjects both with and without migraine and poorly responsive to betahistine alone. Fifty-two MD subjects were included who were poorly responsive to betahistine during 6 months of follow-up; 29 were migraineurs. Combined therapy was administered with betahistine 48 mg/day and cinnarizine 20 mg BID for 1 month, 20 mg/day for 2 weeks and 20 mg every 2 days for 2 more weeks, and then repeated. Results were collected over 6 months of follow-up. MD subjects with and without migraine demonstrated a decrease in both vertigo spells and migrainous attacks during combined therapy (from 9.4 to 3.8 and from 6.8 to 5.9 in 6 months, respectively, for vertigo spells, while migraine decreased from 3.8 to 1 in 6 months, respectively). A correlation was seen between decrease of vertigo spells and headaches in the sample of MD subjects with migraine. Our data support a proactive role for cinnarizine in preventing vertigo spells, especially in MD patients with migraine.

The anterior wall of the maxillary sinus represents a blind spot in maxillary sinus endoscopic surgery because of the absence of proper visualisation and instrumentation to reach it. The aim of this study was to validate a new approach through the oral cavity into the nose with a flexible video endoscope (oro-nasal endoscopic approach; ONEA) to visualise the entire anterior maxillary wall including the anteromedial angle. We started from a dried bone cadaver model, and then dissected fresh-frozen cadavers. The maxillary sinus was explored with a rigid and a flexible endoscope entering from the nose. Next, a flexible endoscope was introduced through the mouth and back up through the choana, it accessed the maxillary middle antrostomy, entering inside the sinus and looking at the anterior wall. A small ruler inserted inside the sinus demonstrated all the angles visualised. The new ONEA technique allows complete visualisation of the anterior wall of the maxillary sinus with inspection of all blind spots. It is therefore possible to detect lesions that would normally not be visible with a normal rigid endoscope. We demonstrate the validity of a novel technique that allows visualisation of the infero-medial angle of the anterior wall of the maxillary sinus.

Purpose: Review of the literature concerning cocaine induced midline destructive lesions (CIMDL)., Methods: We reviewed the English literature regarding CIMDL involving the nose and its surrounding structures. The review is based on a search of the US National Library of Medicine (PubMed) online database from January 1st, 1982 to March 31st, 2013., Results: CIMDL is a pathology that mimics systemic diseases with positive anti-neutrophil cytoplasmic antibodies (ANCA). The prevalence of CIMDL is considered to be about 4.8% among cocaine users. Clinical manifestations include hyposmia, facial pain, crusting, ulcers, nasal septal perforation, palatal perforation, sinus wall destruction, orbital erosion and damage of the anterior skull base. The presence of ANCA directed against human neutrophil elastase (HNE) is the most distinguishing feature of CIMDL. Toxicological tests, indirect immunofluorescence microscopy, antigen specific solid assay testing, histopathological analysis, apoptosis assay and MRI imaging concur in the clinical identification of CIMDL. The pathogenesis of CIMDL is poorly understood and implicates inflammatory, infective, proapoptotic and autoimmune mechanisms., Conclusion: CIMDL must be readily recognized by clinicians to provide appropriate treatment. Immunosuppressive therapy has no role in the treatment of CIMDL. Only abstinence can interrupt the progression of the disease.

Vestibular function is often underdiagnosed in vestibular schwannomas (VS). To evaluate it in a selected group of patients harbouring vestibular schwannomas, 64 patients were included in this study, recruited between March 2008 and June 2011 at our institution. All patients underwent Gd-enhanced MRI and complete neurotological evaluation before gamma knife surgery. Morphological measurements included Koos Classification and quantification of internal acoustic canal filling in length and diameter. Cochlear and vestibular functions were assessed considering pure tone and speech audiometry, bedside examination and caloric test by videonystagmography. A statistical analysis was performed to find possible correlations between morphological and cochleovestibular data. Patients with a higher intracanalicular length (ICL, mean value 8.59 and median 8.8 mm) of the tumour presented a higher value of UW than the subgroup with a lower length (51.9 ± 24.3% and 38.8 ± 18.1% respectively, p = 0.04), while no difference was detected for pure tone audiometry (PTA) values (50.9 ± 22.3 db and 51.1 ± 28.9 db respectively). Patients with a higher ICL also presented a higher rate of positive HIT (88% and 60% respectively, p = 0.006). Patients with a higher value of intracanalicular diameter (ICD, mean value 5.22 and median 5.15 mm) demonstrated higher values of UW (50.2 ± 29.1% and 39.3 ± 21% respectively, p = 0.03), but not different PTA (50.2 ± 29.1 db and 51.9 ± 29.9 db respectively). Finally, patients with a positive head impulse test (HIT) demonstrated significantly higher values of unilateral weakness (UW) (p = 0.001). Vestibular disorders are probably underdiagnosed in patients with VS. ICL and ICD seem to be the main parameters that correlate with vestibular function. Also, in case of small intracanalar T1 VS a slight increase of these variables can result in significant vestibular impairment. The data reported in the present study are not inconsistent with the possibility of proactive treatment of patients with VS.

Schwannomas are rare and slow growing tumours, arising from Schwann cells which provide myelin; less than 1% of them degenerate into a malignant state. Although most studies are based on acoustic schwannomas, the majority of these tumours are non-vestibular and extracranial. Up to 45% of them can be localised in head and neck districts, where they represent a diagnostic challenge because they are in differential diagnosis with lipoma, brachial cyst, paraganglioma and adenopathy. Between February 2002 and September 2012 our experience considers 18 patients affected by schwannomas localised in the neck in 14 cases, in the oral cavity in 2 cases, in the upper lip in 1 case and finally in the nose in 1 case. A painless neck mass was the major symptom referred, as well as dysphonia and oral pain. Ultrasound scan with fine needle aspiration biopsy was done in half of the group and was diagnostic in 30%, whereas magnetic resonance imaging was diagnostic in 77%, confirming its primary role in diagnostic work-up. The surgical approach was mainly by cervical incision and the intraneural extracapsular enucleation was the technique used without nerve injury in 89% of cases. Follow-up period was 6-120 months and no evidence of relapse was registered.

Rhinoplasty is one of the most difficult aesthetic surgery procedures with a high rate of revision. In revision rhinoplasty the surgeon should explore the patient's concerns and then verify the possibility to satisfy expectations after complete internal and external examination of the nose. For the vast majority of complex secondaries, an open approach is the only reasonable method. In fact, in secondary nasal surgery, because of the scarring process following the primary operation, dissection is tedious, and landmarks are lost. One of the main objectives for the surgeon who approaches secondary rhinoplasty is to restore the structural support of the nose and to replace the lost volume of soft tissues. To achieve this purpose, the surgeon must often rely on grafts. An ideal grafting material must be easy to sculpt, resistant to trauma, infection and extrusion, mechanically stable, inert and readily available. For all these reasons, autogenous cartilage grafts harvested from septum, auricular concha and rib represent the first choice in rhinoplasty. In order to obtain a camouflage graft that provides natural contouring to the nose, temporalis fascia can be used. All these carefully trimmed grafts are useful in tip revision surgery, in secondary surgery of the dorsum and to resolve or reduce functional problems.

To assess the possible role of hyperhomocysteinemia (HyHcy) in delaying recovery after acute vestibular neuritis. In our retrospective study, 90 subjects were evaluated within 7 days from the beginning of an acute vertigo. All subjects had high plasma levels of homocysteine (Hcy). 46 patients were treated with homocysteine lowering therapy and betahistine for 1 month, while 44 subjects received only betahistine. Subjective symptoms were evaluated with the Dizziness Handicap Inventory (DHI) questionnaire, administered 7 days after the beginning of vertigo and again after 1 month. Moreover, postural control performed at 1 month' control was studied with static stabilometry in a subgroup of 21 non-treated and 20 treated patients. DHI total score decreased significantly more in the subgroup of subjects treated with homocysteine lowering therapy. Moreover, posturographic data were significantly increased in non-treated compared with treated subjects. Our data support the possibility of a role of HyHcy in preventing recovery after a recent vestibular neuritis. A microvascular disorder or the neurotoxic effect of HyHcy have been considered as possible causal factors. Although not conclusive, our data are not inconsistent with the hypothesis of a poorer adaptation in patients with untreated HyHcy.

To describe a new and useful criterion to identify endoscopically approachable lateral frontal sinus mucoceles. We retrospectively reviewed all patients diagnosed with frontal mucocele with lateral extension who underwent endoscopic sinus surgery (ESS) at the Department of Otorhinolaryngology, San Raffaele Scientific Institute over a 4 year period, from January 2008 to March 2012. We analyzed patient charts, pre- and post-operative imaging, operative reports, postoperative periods, and follow-up records. Our series is composed of seven patients, four males and three females, with a mean age of 56 years. Symptoms at presentation varied depending on the extent of mucocele growth and orbital and intracranial invasion. Mucocele extension medially to a virtual sagittal plane tangential to the medial side of the ocular globe was also evaluated with computed tomography, to determine the appropriateness and feasibility of an ESS procedure. After pre-operative investigations, patients underwent marsupialization of the mucocele with ESS. Postoperative follow-up ranged from 1 to 4 years. At present, all patients remain free of disease, as documented by radiological imaging. In defining endoscopically approachable lesions, it is essential to determine their extension beyond a virtual sagittal plane tangential to the medial side of the ocular globe. The success of the endoscopic procedures described was undoubtedly linked to the localization of the mucocele medial wall. This criterion is more important than the size of the mucocele, and accurate computed tomography evaluation can identify those mucoceles approachable with ESS, even if laterally extended.

Granulomatosis with polyangiitis (Wegener's, GPA) is an uncommon disease of unknown etiology classically involves the ELK triad of the ear, nose, throat (E), lungs (L) and kidneys (K) with necrotizing granulomatous inflammation and vasculitis. Most of the initial symptoms begin in the head and neck region with a wide spectrum of involvement of any site ranging from the nasal septum, paranasal sinuses, oral mucosa, larynx and even the external, middle and internal ear. Diagnosis may be delayed because the onset is heterogeneous and sometimes limited to one organ. The pathologic findings of a characteristic inflammatory reaction pattern, and the serum findings of elevated antineutrophil cytoplasmic antibodies can help to establish the diagnosis. The differentiation from other conditions that mimic GPA such as lymphoma and infections is of critical importance to initiate appropriate treatment. Treatment of the underlying disease is medical with the use of immunosuppressive agents and will not be reviewed here. This review focuses on the otorhinolaryngologic manifestation and complication of GPA as well as their surgical management and specifies the role of the otorhinolaryngologist as an integral member of the multidisciplinary care team for patients with GPA., (Copyright © 2012 Elsevier B.V.

In Europe it is estimated that around 13million of adults (15-64years) have used cocaine at least once in their lifetime. The most frequently used route of administration for the drug is intranasal inhalation, or "snorting", and thus the adverse effects of cocaine on the nasal tract are very common. Habitual nasal insufflations of cocaine may cause mucosal lesions, and if cocaine use becomes chronic and compulsive, progressive damage of the mucosa and perichondrium leads to ischemic necrosis of septal cartilage and perforation of the nasal septum. Occasionally, cocaine-induced lesions cause extensive destruction of the osteocartilaginous structures of nose, sinuses and palate that can mimic other diseases such as tumors, infections, and immunological diseases. Thorough diagnostic workup, including endoscopic, radiologic, histopathologic and serologic testing is imperative to arrive at the proper diagnosis and to initiate appropriate local and systemic treatment. Positive antineutrophil cytoplasmic antibody (ANCA) test results may be found in an unexpectedly large proportion of patients with CIMDL. In several instances their lesions are clinically indistinguishable from granulomatosis with polyangiitis (Wegener's) limited to the upper respiratory tract. CIMDL seem to be the result of a necrotizing inflammatory tissue response triggered by cocaine abuse in a subset of patients predisposed to produce ANCA, particularly those reacting with HNE. The presence of these HNE-ANCA seems to promote or define the disease phenotype. CIMDL do not respond well to immunosuppressive therapy. Only the consistent removal of persistent stimuli of autoantibody production (cocaine, bacterial superinfections) can halt the disease process, prevent the progression of the lesions and promise success of surgical repair procedures., (Copyright © 2012 Elsevier B.V.

Objective: To evaluate the incidence of pharyngocutaneous fistula after pharyngolaryngectomy with and without a Montgomery salivary stent., Design: Retrospective analysis of patients with factors that predispose to the development of pharyngocutaneous fistula (i.e. disease extending to the supraglottic region, base of the tongue or pyriform sinuses, and/or radiochemotherapy)., Subjects: Between 2002 and 2008, 85 pharyngolaryngectomies were performed in our clinic. Of these patients, 31 were at increased risk of fistula development, of whom 45 per cent developed fistulas post-operatively. This subgroup of 31 patients was compared with a second subgroup of 22 patients at high risk of fistula development, treated between 2009 and 2011 with pharyngolaryngectomy and with a Montgomery salivary stent placed in advance during closure of the neopharynx., Results: Statistical analysis showed a significant reduction in the rate of fistula development, from 45 to 9 per cent (p < 0.01), with application of the salivary stent., Conclusion: These data confirm the preventive effect of a salivary stent placed during pharyngolaryngectomy, for patients at high risk of fistula development.

Objective: Current methods of measuring pharyngeal pH are problematic. The aim of the study was to assess the ability of the oropharyngeal pH monitoring (Restech) in predicting the response to proton pump inhibitor (PPI) therapy in patients with gastroesophageal reflux disease-related laryngopharyngeal symptoms., Study Design: The study design is prospective and uncontrolled., Methods: Twenty-two consecutive naive patients with chronic laryngeal symptoms were enrolled. Reflux symptom index, fibrolaryngoscopy, and 24-hour oropharyngeal pH monitoring were performed. Both patients and laryngoscopist were blinded by the results of Restech. All the patients were given a 3-month therapy with pantoprazole of 40mg twice a day and then repeated both the reflux symptom index and fibrolaryngoscopic evaluation. Patients were considered as responders if a five-point decrease in symptom score was recorded., Results: Thirteen of the 22 patients (59.1%) responded to therapy. Laryngoscopic findings did not correlate with the clinical improvement after the 3 months of PPI. Nine patients (40.9%) had a pathologic Restech study, and all resulted responsive to PPI; nine patients (40.9%) with a negative Restech were nonresponsive to PPI, and four patients (18.2%) despite a negative Restech resulted responsive to therapy. Responsive patients showed both a higher oropharyngeal acid exposure in orthostatic position and a higher Ryan score, compared with nonresponders (49.74±58.11 vs 2.12±0.0, P=0.002). Considering responsiveness to medical therapy as the gold standard of laryngopharyngeal reflux (LPR) for the diagnosis of LPR, Restech showed a sensitivity of 69% and a specificity of 100%., Conclusions: The high specificity and reasonable sensitivity of this technique make the Restech an interesting tool before therapy of patients with pharyngoesophageal reflux., (Copyright © 2013 The Voice Foundation.

Objective: To establish a possible causal factor for residual dizziness (RD) after successful repositioning maneuvers in patients with benign paroxysmal positional vertigo (BPPV)., Materials and Method: Ninety consecutive patients with idiopathic BPPV were treated with repositioning maneuvers, and the rate of RD was assessed as well as clinical data. Posturography and assessment of anxiety levels were performed on patients reporting RD. Results were compared with a control group of BPPV patients of the sample after repositioning maneuvers and without RD., Results: Twenty-eight subjects (31.1%) reported RD on the second day after successful repositioning maneuvers. The mean duration of RD was 11.6 ± 3.9 days. Patients with RD presented a higher duration of BPPV (14.1 vs. 10.9 days, p = 0.01). A correlation was demonstrated between the duration of BPPV and duration of RD (p < 0.01). Subjects with RD presented increased body sways, above all in eyes-closed conditions., Conclusion: RD is mainly correlated with duration of vertigo in BPPV patients. Anxiety was demonstrated to play a role in increased body sways., (Copyright © 2013 S. Karger AG, Basel.)

The aim of this work is to assess the clinical and functional outcome of patients who underwent different types of neck dissection, with special regards to the spinal accessory nerve, trapezius muscle and shoulder function. From February 2008 to July 2010, we evaluated 17 cases of neck dissection in patients affected by laryngeal carcinoma clinically staged N0. We performed selective neck dissection (IIA-IIBIII- IV) in 11 cases (group A) and superselective neck dissection in 6 cases (group B). All patients underwent clinical examination before surgery to evaluate shoulder function. They also underwent functional evaluation of the spinal accessory nerve through electromyography (study of muscular activity) and electroneurography (study of motor action potential). Patients were evaluated before surgery (T0), 8 days after surgery (T1) and 21 days after surgery (T2). In all cases, at the end of surgery it was possible to assess the integrity of the spinal accessory nerve. The average value of the MAP was 13.06 in group A and 10.98 in group B at T0. Eight days after surgery (T1) the value of MAP was reduced to 1.35 in group A and 6.15 in group B. Electromyography evaluation showed signs of denervation in 6 cases in group A and in 2 cases in group B. Voluntary activity was not detectable in 6 cases in group A, while it was present, even if reduced, in all cases in group B. At 21 days after surgery (T2), we found a value of MAP of 1.03 in group A and 6.43 in group B. Electromyography showed signs of denervation in 10 patients in group A and in 3 cases in group B. Voluntary activity was not detectable in 10 cases in group A, while it was present in all cases in group B. The arm abduction test was 2.5 in group A and 4.0 in group B. Neck dissection quality of life questionnaire showed a value of 24.17 in group A and a value of 25.5 in group B. Our data thus confirm that surgical manipulation of the nerve may be associated with severe impairment of nerve conduction when sublevel IIB is involved in the dissection.

Radial forearm free flap surgery is a versatile technique that is widely adopted for microvascular reconstruction of the oral, oropharyngeal and hypopharyngeal lining. Nowadays, the technique for harvesting is standardized, while reconstruction of the forearm donor site defect is somewhat controversial. The authors describe a modified closure technique developed to reduce skin tension that provides subsequent improvement of the cosmetic appearance of the forearm donor site. A series of 43 patients undergoing radial forearm free flap (RFFF) reconstruction is presented, carried out by our ENT department between September 2007 and December 2010. The authors used a modification of the standard triangular full-thickness skin graft (FTSG) technique to close the forearm donor site on 23 patients with a new shape similar to a dagger. Using the Stony Brook Evaluation Scale, the authors analyzed the outcomes of 23 cases employing the dagger-shaped FTSG and compared these with a standard (triangular shaped) reconstructive graft used in 20 earlier patients. The new dagger-shaped graft decreases skin tension and reduces the need of multiple slits in the graft with improved aesthetic outcome; it is an effective method for repair of the forearm donor site with low tension and without the need to harvest the skin graft from the thigh. The technique is simple, reliable and requires no more time than a standard procedure.

Object. Aim of our study was to establish some peculiar features of Ménière's Disease (MD) in a group of elderly MD patients, in which the first vertigo spell happened when over 65 years old. Material and Methods. We analyzed a group of 73 younger than 65-years-old and a group of 30 elderly MD patients. All patients underwent a neurotological evaluation, an anamnestic evaluation including a lifetime history of migraine, and blood withdrawal for autoantibody screening. Results. Some differences were found between elderly and younger MD patients. Elderly MD patients presented a higher prevalence of Tumarkin attacks and a lower prevalence of lifetime history of migraine; moreover, they presented a faster develop of hearing loss and vertigo spells than a subgroup of 32 younger patients matched for the duration of illness. Conclusions. Some clinical features of MD in elderly have been pointed out. Particularly, the lower rate of migrainous history and positivity for autoantibodies often associated with MD, in our opinion, support the hypothesis of a vascular disorder acting as a predisposing factor for MD in elderly.

Background: To describe our clinical experience in 218 consecutive patients undergoing endoscopic back-and-forth septoplasty (EBFS), examining surgical indications, technique, and follow-up., Methods: From January 2005 to November 2008, 218 patients underwent EBFS at the Department of Otorhinolaryngology, San Raffaele Hospital, Milan, Italy. The indication for EBFS in this series was nasal airway obstruction (NAO). Patients were studied with nasal rigid endoscopy and in some cases computed tomography (CT) was used to exclude rhinosinusitis. The most common concomitant diagnoses included allergic rhinitis and turbinate hypertrophy. EBFS facilitates the interruption of perichondrial and periosteal bridges, which are more represented in the anterior portion of the septum between the caudal quadrangular cartilage and the vomeropremaxillary crest. Septal splints were positioned. No nasal packing was required., Results: No cases required conversion to a traditional headlight approach, and no intraoperative complications were encountered. Intraoperative mucosal microlacerations occurred in 77.98% of cases; suturing was required in only 8.25% of cases. Of 218 patients, 74.77% experienced resolution of NAO, while 16.06% experienced only improvement; 9.17% noted the persistence of symptoms. Complications included transient dental pain/hypesthesia (6.88%), septal hematoma (5.04%), synechiae formation (2.29%), epistaxis (1.83%), septal perforation (1.83%), cheek swelling (0.45%), and septal abscess (0.45%)., Conclusion: EBFS as a variation of endoscopic septoplasty (ES) represents a viable procedure with good outcomes and a low rate of complications. The technique allows lysis of tissue fibers while preserving the integrity of mucosa at the critical area using less force and reduces the probability of mucosal tears, based on embryologic knowledge of anatomical dissection., (Copyright © 2011 American Rhinologic Society-American Academy of Otolaryngic Allergy, LLC.)

Agoraphobia in panic disorder (PD) has been related to abnormal balance system function. Vision influences balance and behavioural adaptations; peripheral vision influences orienting and fast defensive reactions whereas central vision analyzes details of objects. We have hypothesized that the abnormal balance function in PD could be mainly related to peripheral vision as part of a defensive alarm system in the brain. In 25 patients with PD and agoraphobia and 31 healthy controls we assessed, by posturography, balance system reactivity to video-films projected in peripheral and central visual fields (randomized sequence). Length, velocity and surface of body sway were calculated. Patients increased their body sway during peripheral stimulation, whereas controls did not; the two groups showed a similar increase of body sway during central stimulation. Anxiety levels during peripheral stimulation significantly influenced the postural response in the group of patients. These preliminary results suggest that the higher visual sensitivity to peripheral stimulation in patients with PD and agoraphobia may be linked to a more active "visual alarm system" involving visual, vestibular and limbic areas that might influence the development of agoraphobia in situations where environmental stimuli are uncertain., (Copyright © 2010 Elsevier Ltd.

Even after successful repositioning maneuvers for benign paroxysmal positional vertigo (BPPV), some patients report dizziness lasting for a certain period afterwards. We studied the prevalence and clinical factors associated with residual dizziness in a sample of elderly patients. Sixty outpatients over 65 years of age, affected by idiopathic BPPV were recruited; the exclusion criterion was a history of previous episodes of vertigo, including positional. The patients were asked to describe their self-perceived anxiety for vertigo on a Visual Analogue Scale (VAS) and successively treated with appropriate maneuvers till resolution of nystagmus. Data concerning the demographic and clinical features of BPPV were collected. Patients were followed until complete resolution of subjective dizziness and imbalance without positional nystagmus. Data about residual dizziness were collected from the second day from resolution of BPPV. Clinical and demographic factors related to residual dizziness were analyzed. Twenty-two subjects (37%) reported residual dizziness. In these subjects, the mean duration of residual dizziness was 13.4 ± 7.5 days. No association was observed between residual dizziness and gender, involved canal and the number of repositioning maneuvers before resolution. On the other hand, age older than 72 years, symptom duration greater than 9 days and VAS scale for anxiety greater than 10/100 were associated with an increased risk of residual dizziness. The odds ratio were respectively 6.5 (age-residual dizziness, Confidence Interval 95%), 6.5 (duration of vertigo-residual dizziness, Confidence Interval 95%) and 15.5 (anxiety levels-residual dizziness, Confidence Interval 95%). Longer symptom duration before diagnosis was associated with higher anxiety levels. The results underline the necessity for an early and correct diagnosis of BPPV, especially in the elderly.

Fine-needle aspiration cytology guided by ultrasound imaging is a widely used diagnostic tool to evaluate neoplastic or inflammatory lesions of salivary glands. From February 2002 to February 2008 all the parotid lesions removed surgically in our Unit of Otolaryngology were reviewed. Study focused on sensitivity, specificity, accuracy, predictive values, likelihood ratios, and Kappa statistics for fine-needle aspiration cytology vs histological diagnosis in 176 cases. Fine-needle aspiration cytology sensitivity and specificity were 81% and 99%, respectively. Accuracy for malignancy was 97%, accuracy for benignity was 83%; positive and negative predictive values were 93% and 98%, respectively; likelihood ratio of positive and negative test results were 100.3 and 0.19, respectively ("positive" was used to define "malignant"). The prevalence of malignancy was 0.114. Kappa statistics for the degree of agreement between fine-needle aspiration cytology and histological results were 0.85 (95% CI = 0.71-0.99). Pre-operative fine-needle aspiration cytology diagnosis improves surgical treatment of parotid masses.

Objective/hypothesis: The purpose of the study was to assess the satisfaction and quality of life in laryngectomees after vocal rehabilitation using voice prostheses. We evaluated the impact on quality of life between laryngectomees with voice prostheses, laryngectomees without them and healthy controls., Methods: This was a prospective study on a sample of laryngectomees in an Italian university hospital. Our study population was composed of 42 patients who had previously undergone a total laryngectomy; in 24 of them, voice rehabilitation was obtained with a voice prosthesis device (group A), while 18 of them learned oesophageal voice (group B). The results were compared with a group of 25 healthy controls (group C). In order to investigate the quality of life, we administered the Short Form 36-Item Health Survey (SF-36) to the 3 groups. Moreover, self-satisfaction of the subjects in group A was assessed by single questions regarding their use of the voice prosthesis., Results: A statistical difference in the SF-36 was detected for social functioning (SF) between groups A and B. Role physical, SF and role emotional were significantly better in group C than in group A. Group A stated they were very satisfied with voice quality while there were still some problems regarding prosthesis lifetime and communication at the telephone or in noisy environments., Conclusions: Voice prosthesis implantation in laryngectomees showed positive effects on patients' quality of life; however, there are still some negative aspects. At present, an early diagnosis of larynx cancer with a partial laryngectomy in order to preserve phonatory function is the gold standard., (Copyright © 2011 S. Karger AG, Basel.)

Recent reports have focused on a possible association between migraine and Menière's disease; patients suffering from Menière's disease present a higher rate of migraine. In some cases, the clinical features of migraine-associated vertigo may mimic the presentation of Menière's disease. The present report focuses on two cases of females with recurrent episodes of rotational vertigo, fluctuating hearing loss and tinnitus lasting from a few minutes to several hours; both cases also presented migrainous attacks. As a result of repeated cochleovestibular attacks, both patients presented a permanent low frequency sensorineural hearing loss. Preventive therapies for Menière's disease did not reduce vertigo attacks, while topiramate and acetylsalicylic acid treatment resulted in a significant reduction of both migraine and vertigo. Both the diagnosis of Menière's disease and of migraine-associated vertigo rely on clinical history and both disorders lack a specific diagnostic test. In the early stages, differential diagnosis between Menière's disease and migraine-associated vertigo is often very difficult; previous investigations focused on the possibility that subjects with migraine may experience all symptoms of Menière's disease, including sensorineural fluctuating hearing loss. In conclusion, a trial with prophylactic drug treatment for migraine might be suggested in patients with clear symptoms of migraine and recurrent cochleovestibular disorders.

Objectives: This study sought to establish the prevalence of vestibular disorders, migraine and definite migrainous vertigo in patients with psychiatric disorders who were referred for treatment of dizziness, without a lifetime history of vertigo., Study Design: Retrospective study., Setting: Out-patients in a university hospital., Materials and Methods: Fifty-two dizzy patients with panic disorders and agoraphobia, 30 with panic disorders without agoraphobia, and 20 with depressive disorders underwent otoneurological screening with bithermal caloric stimulation. The prevalence of migraine and migrainous vertigo was assessed. The level of dizziness was evaluated using the Dizziness Handicap Inventory., Results: Dizzy patients with panic disorders and agoraphobia had a significantly p = 0.05 regarding the prevalence of peripheral vestibular abnormalities in the group of subjects with PD and agoraphobia and in those with depressive disorders. Migraine was equally represented in the three groups, but panic disorder patients had a higher prevalence of migrainous vertigo definite migrainous vertigo. Almost all patients with a peripheral vestibular disorder had a final diagnosis of definite migrainous vertigo according to Neuhauser criteria. These patients had higher Dizziness Handicap Inventory scores. The Dizziness Handicap Inventory total score was higher in the subgroup of patients with panic disorders with agoraphobia also presenting unilateral reduced caloric responses or definite migrainous vertigo, compared with the subgroup of remaining subjects with panic disorders with agoraphobia (p < 0.001)., Conclusions: Our data support the hypothesis that, in patients with panic disorders (and especially those with additional agoraphobia), dizziness may be linked to malfunction of the vestibular system. However, the data are not inconsistent with the hypothesis that migrainous vertigo is the most common pathophysiological mechanism for vestibular disorders.

Objective: Endogenous Ouabain (EO) has been demonstrated to modulate the activity of Na+, K+ -ATPase. Our purpose was to measure plasma levels of EO in Ménière's Disease (MD) subjects as a possible predisposing factor to developing and maintaining hydrops., Study Design: Case-control study., Settings: University hospital., Patients: Thirty-nine MD subjects and 29 controls with a lifetime negative history for vertigo and dizziness., Main Outcome Measures: Plasma levels of EO., Results: Plasma EO in MD subjects was in the range between 33 and 504 pmol/L (median, 135.5 pmol/L), whereas in the control group, plasma EO varied between 70 and 724 pmol/L (median, 205 pmol/L). The Mann-Whitney U test detected a statistically significant difference (p = 0.0001)., Conclusion: Low plasma levels of EO have been proposed to augment Na-K pump activity, whereas high EO levels show an inhibitory effect on the pump activity. A proper pump activity may be necessary to keep the right ionic amount and osmolarity in endolymph. Although other possibilities may be considered, we suggest that altered control mechanisms of pump activity may be related to the pathogenesis and maintenance of MD.

Objective: Aim of the present review is to offer a concise but complete discussion about pathologies with pediatric otorhinolaryngological interest recognizing: (i) growth disorders, (ii) chromosomal disorders, and (iii) tumors., Methods: Pathologies characterized by a growth anomaly have been grouped, underlining the characteristics of otorhinolaryngological interest. Numerous syndromes typical of the pediatric age have been reported and classified according to the ailments of the orofacial district. Tumoral pathologies, for which the otorhinolaryngological operation is fundamental, have been descripted. We reviewed recent literature and older papers. We did not find recent literature regarding otorhinolaryngological features related to some of the pathologies described., Results/conclusions: Otorhinolaryngologists should be familiar with pediatric disorders, since many of them have head and neck manifestations. This knowledge allows to treat them with a correct surgical approach, in order to implore children's quality of life., (Copyright 2009 Elsevier Ireland Ltd. All rights reserved.)

Endoscopic dacryocystorhinostomy (DCR) is a well-established alternative to external approaches in the treatment of nasolacrimal canal obstruction. From July 2004 to December 2008, 92 endoscopic DCRs were performed on 88 patients at the Department of Otorhinolaryngology, San Raffaele Hospital, Milan. All patients were affected by chronic dacryocystitis with epiphora. Preoperative work-up included Jones tests, lacrimal pathways irrigation, nasal endoscopy, and imaging evaluation by computed tomography. The technique involved anastomosis of nasal mucosal, lacrimal sac flaps and a large bony ostium. A silicone tube was inserted in all patients that remained for a period of 3 months. The first endoscopic intervention was successful in 91.30% of patients. After a second revision endoscopic DCR, the overall success rate raised to 95.65%. Anastomosis of nasal mucosal between lacrimal sac flaps plays a key role in endoscopic DCR with a high success rate both in primary nasolacrimal obstructions and in revision cases.

Mucous membrane pemphigoid includes chronic autoimmune sub-epithelial blistering diseases that predominantly affect mucous membranes, with varying combinations of oral, ocular, cutaneous, genital, nasopharyngeal, oesophageal and laryngeal lesions. The case is reported of a man with multiple manifestations of mucous membrane pemphigoid. A 53-year-old male presented at our Department with a 4-year clinical history of diagnosed cicatricial pemphigoid. The patient was affected by ocular and urinary symptoms and presented with nasal obstruction and dysphonia. Nasal endoscopy revealed crusting and synechiae with pale and atrophic mucosa. Computed tomography examination showed hypodense-hyperdense material occupying all paranasal sinuses and nasal fossae. Laryngoscopy showed anterior para-commessural and inter-arytenoidal synechiae. The patient underwent functional endoscopic sinus surgery for incision of synechiae and removal of scars and inflammatory material from all sinuses. Nasal splints were then inserted. A wait-and-see policy was adopted for the laryngeal lesion. One year later, the splints were removed; the upper airways were still free and there were no signs of nasal obstruction. An endoscopic approach appears to be efficacious in the surgical treatment of nasal cicatricial pemphigoid, and long-term stenting may be necessary to avoid recurrence. Although surgery has not a curative role in long-term therapeutic strategies, it may, nonetheless, improve the quality of life and ensure good nasal respiration.

Objectives: To assess the efficacy of rehabilitation for dizzy patients after recent acute vestibular disturbance., Methods: Forty patients recently hospitalised for an acute episode of rotational vertigo which lasted days were randomly divided into two groups. The first group (20 patients; group R) underwent active rehabilitation, while the second group (20 patients; group C) were told only to 'perform their daily activities'. Group R subjects underwent a total of 10 sessions of rehabilitation, including exercises on a stabilometric platform, point de mire and a series of five exercises repeated five times daily. All patients performed static stabilometry (posturography), undertook the dynamic gait index test, and completed a dizziness handicap questionnaire and a visual analogue scale for anxiety, at baseline and on completion., Results: At 25 days, the rehabilitated patients obtained better results for all recorded outcomes, compared with the control group. The greatest difference in the rehabilitated subjects, compared with the control group, was for the dynamic gait index test; however, this difference was not statistically significant. The visual analogue scale anxiety score was statistically significantly more reduced in rehabilitated patients compared with control patients. Control patients maintained a higher visual dependence for postural control., Conclusions: These results would appear to support the effectiveness of a supervised exercise programme for patients following acute onset of vestibular disturbance. A correlation was found in both groups between dynamic gait index results and anxiety. In our experience, a rehabilitation programme seems to reduce dependence on visual cues for postural control.

Background: Association between migraine and vertigo has been widely studied during the last years. A central or peripheral vestibular damage may occur in patients with migrainous vertigo. Despite much evidence, at present the International Headache Society classification does not include a specific category for migrainous vertigo., Objectives: To assess the prevalence of central and peripheral vestibular disorders and postural abnormalities in patients diagnosed as affected by definite migrainous vertigo according to Neuhauser., Methods: Thirty patients with migraine and acute vertigo lasting from minutes to hours underwent a full otoneurological screening for spontaneous, positional, and positioning nystagmus with head-shaking and head-thrust (Halmagyi) tests, an audiometric examination, and videonystagmography with bithermal stimulation according to Freyss. Videonystagmographic findings were compared with those of 15 migraineurs without lifetime vertigo (group M). Next day, a static posturography was performed; posturographic results have been compared with those of a second control group of 30 healthy patients matched for age and sex (group C)., Results: In total, 14 subjects with migrainous vertigo showed otovestibular disorders; 6 subjects showed impaired vestibulo-oculomotor reflexes (20%). Five more patients had bilateral increased responses (16.6%). Five patients showed signs of central brainstem or cerebellar disorders for altered pursuit or saccades or positional direction changing nystagmus. Stabilometric results returned higher values of Length and Surface above all when testing was performed in eyes closed conditions compared with the normal control group. The subgroup of 14 subjects with migrainous vertigo and vestibular abnormalities performed poorly in stabilometric exams and seemed to rely more on visual cues in balance control than the subgroup of 16 subjects with migrainous vertigo but without abnormalities., Discussion: Our results indicate that vestibular functional damage may occur in all vestibular pathways; central and peripheral signs are equally represented. Our data are not inconsistent with the hypothesis that a vestibulo-spinal dysfunction is the causal factor for the posturographic results. Moreover, the Visual Romberg Index is significant for increased visual cue dependence in migraineurs.

Objectives: Our randomized, double-blind, placebo-controlled study evaluates the possible benefit of peritonsillar infiltration with 0.75% ropivacaine hydrochloride on the pain level after adenotonsillectomy in 3- to 7-year-old children., Methods: We randomly administered intraoperative peritonsillar infiltration with 0.2 mL/kg ropivacaine 0.75% (group R) or 0.2 mL/kg saline 0.9% (group F) to sixty 3- to 7-year-old children (ASA 1 or 2) who were undergoing adenotonsillectomy. Postoperative pain was assessed 6 and 24 hours after surgery by a 6-face Faces Pain Scale that allowed quantification of pain on a 100-mm horizontal line (0 = no pain). The number of rectal doses of acetaminophen-codeine required during the first postoperative day was recorded., Results: The pain scores did not differ between the groups, either 6 or 24 hours after surgery (group F, 43 +/- 26, versus group R, 29 +/- 23, and group F, 24 +/- 23, versus group R, 30 +/- 28, respectively). Acetaminophen-codeine doses were similarly required in the two groups., Conclusions: Peritonsillar infiltration with 0.75% ropivacaine does not provide any major postoperative analgesic effect in 3- to 7-year-old children after adenotonsillectomy. A possible clinically minor analgesia 6 hours after surgery is suggested.

Objectives: To establish the efficacy of low-level laser therapy for tinnitus., Methods: We performed a prospective, randomized double-blind study on 60 outpatients with tinnitus presenting sensorineural hearing loss in the affected ear. They were randomly divided into two groups, the first performing active laser therapy 20 min a day for 3 months with a 650-nm, 5-mW soft laser (group L), the second using a dummy device which duplicated all aspects of active laser therapy except for the activation of the laser beam (group C). One subject in both groups dropped out due to an increase in tinnitus loudness. Two more patients in each group ceased to comply with the protocol due to familiar problems., Results: The Tinnitus Handicap Inventory (THI) was considered the main outcome measure; no statistical difference was detected between the 2 groups in the THI total score (p = 0.97), and its functional (p = 0.89), emotional (p = 0.89) and catastrophic (p = 0.89) subscales. Moreover, a visual analog scale for self-perceived loudness of the tinnitus showed no difference between the groups (p = 0.69). Regarding psychoacoustic parameters, the minimum masking level showed no difference (p = 0.42), while loudness expressed in sensation level exhibited lower values in group L (p = 0.0127). Group L subjects also presented a decreased rate of hyperacusis (p = 0.02). No changes were detected in the audiometric threshold in both groups., Conclusions: Soft laser therapy demonstrated no efficacy as a therapeutic measure for tinnitus., (2008 S. Karger AG, Basel.)

Objective: To investigate vestibular function in human immunodeficiency virus positive subjects., Methods: We studied vestibular function in 60 human immunodeficiency virus positive subjects reporting dizziness. All three Center for Disease Control and Prevention categories of human immunodeficiency virus infection were represented in the study group (30 patients in class A, 20 in class B and 10 in class C). Subjects had had no previous history of acute vertigo. All subjects underwent: neurotological screening for spontaneous, positional and positioning nystagmus, using head-shaking and head-thrust (Halmagyi) tests; audiometrical examination; and electronystagmography with bithermal stimulation (Freyss' method). The results of the 30 class A subjects were compared with those of 30 human immunodeficiency virus negative patients reporting dizziness., Results: Abnormal otoneurological findings increased progressively from the A to C categories, particularly regarding increased central damage (3.3 per cent of class A, 35 per cent of class B and 100 per cent of class C subjects). In contrast, the incidence of peripheral vestibular disorders remained almost the same, comparing the three categories (33.3 per cent in class A and 50 per cent in classes B and C subjects). Moreover, a higher number of human immunodeficiency virus positive subjects showed abnormal otoneurological findings, compared with the dizzy, human immunodeficiency virus negative subjects., Conclusions: In our opinion, a vestibular disorder may occur in human immunodeficiency virus positive patients as a result of direct viral damage, even in the early phase of infection. Central vestibular damage may be established later on, and may be linked to different causes (e.g. superinfections, vascular causes and drug toxicity).

Herein the case is reported of a synchronous parapharyngeal space pleomorphic adenoma arising from the pharyngeal prolongation of the parotid gland and the contralateral submandibular gland, diagnosed in a young Caucasian female. Case reports and recent literature are presented. Upon physical examination, asymmetry of the lower part of the right side of the face with overlying intact skin, and a submucosal firm swelling, filling the ipsilateral side of the oropharyngeal wall, involving the right tonsillar bed which was medially displaced was immediately recognizable. The patient did not complain of dysphagia. Palpating the left submandibular region, a painless, mobile, rounded mass, 10 mm in diameter, apparently located in the submandibular gland, was detected. Magnetic resonance imaging showed that both lesions were well-defined and encapsulated. The surgical approach is discussed. Cytological diagnosis was that of a typical pleomorphic adenoma. To the best of our knowledge this is the second case report in the English literature of a concomitant pleomorphic adenoma located both in the parapharyngeal space and the submandibular gland.

Objective: Ménière's disease (MD) is an inner ear disorder characterized by recurrent episodic vertigo, hearing loss that is fluctuating in the first stages, aural fullness, and tinnitus. Raised endolymphatic pressure (hydrops) is commonly accepted as a causal condition. Approximately 90% of cases of MD are sporadic, whereas the remaining 10% of cases are linked to genetic factors. The ionic composition of endolymph may also depend on the activity of Na, K-ATPase. Adducin is a heterodimeric cytoskeleton protein consisting of 3 subunits (alpha, beta, and gamma) coded by 3 different genes (ADD1, ADD2, and ADD3). ADD1 Gly460Trp polymorphism is associated with salt-sensitive hypertension and increased Na-K pump activity in transfected cells. This study aims to verify the role of adducin in the development of MD., Methods: We genotyped 28 patients affected by definite MD according to American Academy of Otolaryngology-Head and Neck Surgery Foundation criteria. Results were compared with those from 2 different control populations (normotensive control group from San Raffaele Hospital and general population group)., Results: We have not found any significant difference in the distribution of ADD2 C1797T and ADD3 IVS11+386A/G polymorphism genotypes. On the other hand, the frequency of ADD1 Trp allele is significantly increased in patients with MD compared with controls., Conclusion: We present data supporting the possibility that increased Na, K-ATPase activity may be one of the pathologic mechanisms inducing hyperosmolarity in endolymph which, in turn, may lead to hydrops.

Objective: To assess the efficacy of low-level laser therapy (LLLT) for Ménière's disease (MD)., Materials and Methods: Twenty patients with unilateral MD were included in the study; all presented with uncontrolled vertigo. The patients were randomly divided into two groups: group 1 patients received LLLT 20 min a day with a 5-mW soft laser for 6 mo, while group 2 received betahistine 16 mg twice a day for 6 mo. According to American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guidelines, the main outcome for vertigo control was considered to be the number of spells per month in the 6 mo before treatment compared with the same parameter in the 6 mo of therapy. The duration of spells expressed in minutes was also considered. Moreover, a hearing test was performed before and after therapy and results were reported as the pure tone average of 500-, 1000-, 2000-, and 3000-Hz frequencies. All results were valued at baseline, and after 3 and 6 mo of therapy., Results: Compared to baseline, the number and duration of spells were significantly reduced in both groups; statistical significance was detected for the 3-mo control in both groups (p 0.05 with the multiple pair comparison test). Betahistine seems to have a faster action in spell reduction (p 0.05 comparing the 3-mo results between the two groups). Audiometric examination did not show a statistically significant difference between the two groups., Conclusions: In our experience, LLLT seems to prevent vertigo spells in MD, although results indicate that it has a slower action than betahistine. Dose-dependent therapeutic effects could explain the last result. In our opinion, increased blood flow in the inner ear is the main mechanism leading to the therapeutic results.

Objective: We report a case of a 58-year-old man suffering from stiff-person syndrome and recurrent peripheral vertigo., Method: A case report and a review of the recent literature on stiff-person syndrome are presented., Results: The patient presented with recurrent episodes of vertigo with a pure peripheral pattern and with concomitant episodes of burning muscle pain, muscle twitching, weight gain and fatigue, worsening with tension or stress that also occurred in periods without vertigo. Cochlear examinations only showed presbyacusis-like hearing loss. The diagnosis of stiff-person syndrome was made with electromyographic examination and from findings in the blood and cerebrospinal fluid of high titres of anti-glutamic acid decarboxylase (GAD67) autoantibodies. In a two-year follow-up period, therapy for stiff-person syndrome abolished episodes of both stiffness and vertigo., Conclusion: As far as we know, no other clinical case of acute vestibular damage with a possible correlation with anti-glutamic acid decarboxylase antibodies has been described. Peripheral vertigo possibly related to a lack of gamma aminobutyric acid underlines a possible role of gamma aminobutyric acid as a neurotransmitter in the peripheral vestibular system.

Sildenafil (Viagra) is a selective phosphodiesterase type 5 inhibitor (PDE5-I) approved for treatment of erectile dysfunction. Although relatively well-tolerated, sildenafil is associated with undesired effects including headache, flushing, dyspepsia, nasal congestion, and visual disturbances. In the present study we explored the impact of sildenafil on nasal airway parameters in young potent men. Eleven men (age 26.0 +/- 1.8 years) with normal BMI (25.7 +/- 0.5) and without nasal respiratory disorders were enrolled in a double-blind, crossover study. All men underwent evaluation of systolic (SBP) and diastolic blood pressure (DBP), heart rate (HR), SpO2%, acoustic rhinometry, and nasal endoscopy before and after placebo or sildenafil (50 mg) plus visual sexual stimulation (VSS). Nasal examination was performed using 0 degrees rigid telescopes, 4 mm in diameter. A Student's t test was used for direct comparisons, while the Kruskal-Wallis test (K-W) was utilized for multiple comparisons. After administration of sildenafil plus VSS, the minimum cross sectional area (MCA) was significantly lower that observed with either placebo (P = 0.03) or sildenafil alone (P = 0.003). However, the post-stimulation values did not demonstrate any significant differences among the different treatment arms (P = 0.48; DF = 2; K-W test). In contrast, endonasal volume (VOL) was significantly lower after sildenafil + VSS (P = 0.01), but not after placebo + VSS (P = 0.18). None of the other parameters monitored showed any significant variations. Rhinoscopy showed a characteristic increase of the volume of the inferior turbinates, with subjective differences between placebo and sildenafil. These preliminary results suggest that sildenafil reduces nasal volume, and that sexual stimulation may decrease nasal airflow by itself.

In order to investigate the relationship between chronic dizziness and vestibular function in patients with panic disorder, in the present study neurotologic findings in 15 patients with panic disorder and chronic dizziness were compared with those in 15 patients with chronic dizziness, without panic disorder. All underwent neurotologic screening for spontaneous, positional and positioning nystagmus with head-shaking and head-thrust tests, an audiometric examination and electronystagmography with bithermal stimulation according to Freyss. A significantly higher number of patients with panic disorder and chronic dizziness showed pathological neurotologic findings in comparison to subjects with chronic dizziness only (9 and 2 patients, respectively; p < 0.05). Most patients with panic disorder showed signs of peripheral vestibular disorders. These results suggest that the complaint of dizziness in patients with panic disorder may be linked to a malfunction of the vestibular system and vestibular disorders may play a role in the pathophysiology of panic disorder. Possible mechanisms underlying this finding are discussed. In patients with panic disorder and chronic dizziness between panic attacks, a careful neurotologic examination is warranted.

Background: Pentraxin 3 (PTX3) and complement component C1q are humoral factors of innate immunity, produced at sites of inflammation, and are essential in immune defense against several microbes such as Aspergillus, which is commonly implicated in nasal polyposis., Methods: PTX3 and C1q were measured in nasal polyp tissue, normal nasal mucosa, and serum of patients and healthy subjects. Immunohistochemistry for the two proteins was done on normal nasal mucosa and nasal polyps. In addition, PTX3 and C1q production from mononuclear cells from patients and healthy subjects was assessed., Results: Normal nasal mucosa was found to have 100-fold higher levels of PTX3 compared with serum. No measurable local increase of PTX3 was observed in polyps compared with normal mucosa. Immunohistochemistry revealed PTX3 expression in the lining of blood vessels both within normal mucosa and nasal polyps. PTX3 also was present in mononuclear cells infiltrating nasal polyps. C1q levels were higher in polyps than in normal nasal mucosa., Conclusion: High levels of PTX3 are present in normal nasal mucosa, suggesting a role in the maintenance of tissue homeostasis. Elevated C1q levels in nasal polyps might be indicative of an ongoing inflammatory response in the nasal mucosa in these patients.

Myosin VI is the only myosin that moves toward the minus end of actin filaments, suggesting a unique biological function. Here, we show that myosin VI is present in the nucleus of mammalian cells where it colocalizes with newly transcribed mRNA and with RNA polymerase II (RNAPII) and is detected in the RNAPII complex. The colocalization and interaction of myosin VI with RNAPII require transcriptional activity. Chromatin immunoprecipitation (ChIP) demonstrates that myosin VI is recruited to the promoter and intragenic regions of active genes, encoding urokinase plasminogen activator (uPA), eukaryotic initiation factor 6 (p27/eIF6), and low-density lipoprotein receptor (LDLR), but not to noncoding, nonregulatory intergenic regions. Downregulation of myosin VI reduces steady-state mRNA levels of these genes in vivo, and antibodies to myosin VI reduce transcription in vitro. We suggest that myosin VI modulates RNAPII-dependent transcription of active genes, implicating the possibility of an actin-myosin based mechanism of transcription.

Main purpose of this study was to evaluate vestibular function, focusing attention on percentage of peripheral damage in 30 HIV positive patients (23 male, 7 female), age range 26-68 years, belonging to Categories A-C of CDC classification of infection, underwent electronystagmography with bithermic stimulation according to Freyss (125 cc of water at 30 degrees C and 44 degrees C in 30 sec). The angular velocity of slow phase was considered as the main value of labirinthine functionality. Peripheral vestibular damage has been found in 35.7% of Class A patients; a similar percentage of peripheral signs was found in Classes B and C, where, on the contrary, increased central vestibular signs were observed. In order to evaluate equilibrium in these patients, a Dynamic Gait Index (DGI) test was performed. Scores were >21 points in 85.7% of Class A patients and decreased in Classes B and C.

Background: A threatening occurrence in some cocaine abusers is the progressive destruction of nasal structures (cocaine-induced midline destructive lesions [CIMDL]) that may end in a highly severe disease., Methods: Thirty patients with CIMDL, 10 healthy patients, 10 patients affected by nasal polyposis, and 10 patients affected by Wegener granulomatosis were observed. Biopsy specimens of nasal mucosa were analyzed by immunohistochemistry for caspases-3, -9 and -8 and by the terminal deoxynucleotidyl transferase-mediated dUTP-digoxygenin nick end labeling (TUNEL) method. The time and concentration-dependent effects of cocaine in vitro were studied in HaCat cells by TUNEL and Western blotting., Results: All CIMDL biopsy specimens showed abundant caspase-3 and caspase-9 expression but no caspase-8 positive cells. No obvious expression of any caspases was detected in biopsy specimens from healthy subjects or in patients affected by nasal polyposis or Wegener granulomatosis. In HaCat cells cellular changes were observed, which confirmed induction of massive apoptotic events. The rate of apoptosis in HaCat cells was dependent on the concentration of cocaine. After 1 hour, 2.5, 5, and 10 mM of cocaine induced 16, 45, and 84% of apoptotic figures, respectively, while 6 hours of exposure increased apoptosis to 25, 54, and 94% at the same concentrations. Caspase expression and activation in HaCat cells treated with 100 microM and 1 mM of cocaine for 1 hour were confirmed by Western blotting., Conclusion: Cultured epithelial cells show both time- and dose-dependent increases in apoptosis and cellular damage on cocaine treatment. We suggest that some abusers trigger CIMDL by abnormally boosting apoptosis within nasal epithelial cells. Cocaine abusers with higher apoptotic rates may predict whether they will eventually develop CIMDL.
