Is it possible to diagnose Posterior Semicircular Canal BPPV from the sitting position? The role of the Head Pitch Test and the upright tests along the RALP and LARP planes. Am J Otolaryngol 2022; 43:103474. [PMID: 35561430 DOI: 10.1016/j.amjoto.2022.103474] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 04/25/2022] [Accepted: 05/01/2022] [Indexed: 01/04/2023]
Abstract
PURPOSE The diagnosis of benign paroxysmal positional vertigo (BPPV) involving the posterior semicircular canal (PSC) is traditionally entrusted to positioning tests where patients are rapidly brought in the supine position. This prospective study aims to define the role of a diagnostic protocol for PSC-BPPV including only upright tests. MATERIALS AND METHODS 109 patients with PSC-BPPV were enrolled. The Head Pitch Test (HPT) was carried out first. If uneventful, the patient's head was turned 45° to each side and bent back-and-forth along the plane aligning either with the right anterior-left posterior (RALP) or left anterior-right posterior (LARP) canals, thus performing the upright RALP / upright LARP (uRALP/uLARP) test. Nystagmus observed was used to predict the diagnosis, which was therefore confirmed by Dix-Hallpike tests. RESULTS PSC-BPPV could be correctly diagnosed in 75.2% of cases with the sole HPT and in 87.2% of cases by adding the uRALP/uLARP test (Upright Protocol). The time elapsed from symptoms onset was closely related to the protocol sensitivity, as it reached 100% (64/64) in acute patients while decreased to 68.9% (31/45) in cases evaluated after 7 days (p < 0.001). CONCLUSIONS Upright maneuvers could correctly diagnose PSC-BPPV in most cases. uRALP/uLARP test demonstrated to improve the sensitivity of the HPT, mainly in recent-onset BPPV.

Abstract
Good fundamentals of posture and balance are essential for the efficient performance of both simple daily tasks and more complex movement patterns. In particular, postural balance is the ability to keep the body in equilibrium and to regain balance after the shift of body segments: postural control mechanisms of integration of the visual, vestibular and foot afferential channels contribute to this. This document provides recommendations based on scientific evidence, clinical practice, and consensus between experts concerning the prevention, diagnosis, and treatment of postural dysfunction at the three stages of life as the developmental age, adult age, and old age > 65 years and follows the "National Guidelines on Classification and Measuring of Posture and its Dysfunctions" per the Italian Ministry of Health (December 2017). The paper answers four main questions: i) "Which measures can be adopted to prevent postural dysfunctions?" ii) "What can we do in order to make a correct diagnosis of postural dysfunction?" iii) "What are the correct treatment programs for postural dysfunctions?" iv) Which professional competencies and experiences are useful for preventing, diagnosing and treating postural dysfunctions? By the Consensus of the Experts and the scientific evidence, emerge that the approach to postural dysfunctions requires a multidisciplinary and interdisciplinary team. Furthermore, rehabilitation treatment interventions must be specific to the age groups that have been indicated, to consider the integration of the main systems and subsystems of postural control that change with age.

Abstract
PURPOSE Sudden sensorineural hearing loss (SSNHL) has similarities to conditions with vascular etiologies such as myocardial infarction and cerebral stroke. Thus, it could be considered as an early sign of a vascular disease and not only a specific local condition. Chronic hypoperfusion in the brain districts leads to a chronic ischemic damage, called cerebral small vessel disease (CSVD), detectable with brain magnetic resonance imaging (MRI). METHODS The authors used CSVD to establish the presence of vascular risk factors in individuals with SSNHL and used the Fazekas score scale to classify them. RESULTS Our study showed that individuals with SSNHL aged between 48 and 60 years have 26% more probability to have a Fazekas score higher than 1 compared to the general population. Individuals younger than 28 years showed a statistically significant negative correlation to have a Fazekas score higher than 0. The higher is the Fazekas score, the less is the probability of hearing recovery. The medium hearing-recovery probability is 46%. This decreases by 16% for every increase of score in the Fazekas scale. In the present study, the recovery probability decreased from 80% in individuals younger than 48 years with a score of 0 to 14% in individuals with a Fazekas scores of 3 and 4. CONCLUSIONS The authors assessed a higher prevalence of CSVD compared to the general population in patients aged between 48 and 60 years with SSNHL. Moreover, they assessed that the presence of CSVD is related to a decreased probability of recovery, as it has already been demonstrated for stroke.

Approach to residual dizziness after successfully treated benign paroxysmal positional vertigo: effect of a polyphenol compound supplementation. Clin Pharmacol 2019; 11:117-125. [PMID: 31534374 PMCID: PMC6681902 DOI: 10.2147/cpaa.s210763] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Accepted: 06/25/2019] [Indexed: 11/23/2022] Open
Abstract
Purpose To assess if a polyphenol compound supplementation (Vertigoval®) could improve residual dizziness earlier after benign paroxysmal positional vertigo (BPPV) and relieve patients from this disabling symptomatology. Methods In this prospective, multicentric study, 127 patients were randomized in the treatment group (TG), who received a 60-day supplementation, while 131 patients were randomized in the control group (CG), who did not receive any medication. The dizziness handicap inventory (DHI) score, static posturography, and the visual analog scale (VAS) for both dizziness (D-VAS) and nausea/vomit (N/V-VAS) were used as measures of outcome at baseline and after 30 and 60 days. Patients were asked about efficacy and tolerance to the treatment. Side effects were examined. Results A statistically significant greater decrease was established in the TG for DHI, D-VAS, and N/V-VAS compared to the CG. On the other hand, static posturography did not show statistical differences between the two groups, though a better clinical improvement after 60-day supplementation was shown in the TG in comparison to the CG. We counted mild side effects in only 2 patients. Most patients reported an excellent or good efficacy and tolerance to the treatment. Conclusion Residual dizziness is a frequent condition of unknown origin that manifests as persistent disabling imbalance after successful repositioning maneuvers for BPPV. The decreasing postural control can affect the quality of life, contributing to falling and psychological problems. The supplementation with the polyphenol compound used in our study is safe, manageable, and appeared to be able to reduce subjective symptoms and improve instability earlier, decreasing the risk of potential complications.

Abstract
Intravestibular intralabyrinthine schwannomas (ILSs) are uncommon benign tumors that arise from the saccular, utricular, and lateral and superior ampullary nerves. According to the literature, there is an average delay of 8 years between the onset of symptoms and diagnosis. The diagnosis is based on an audiovestibular examination and magnetic resonance imaging (MRI). We describe a case of intravestibular ILS in which we included the ocular vestibular evoked myogenic potentials (oVEMPs) test in the diagnostic workup. The oVEMPs test is a relatively new neurophysiologic diagnostic modality that evaluates the superior vestibular pathway and the ascending contralateral pathway through the vestibulo-ocular reflex. In our case, a 65-year-old man presented with progressive right-sided sensorineural hearing loss, dizziness, and tinnitus and fullness in his right ear. Audiovestibular examination and MRI detected an intravestibular ILS on the right. We found that oVEMPs were absent on the contralateral side, which contributed to the diagnostic process. The detection of oVEMPs can provide detailed information on the functionality of the macula of the utricle and the lateral and superior ampullary nerves, with a precise identification of the affected area. Based on our findings, we discuss the role of oVEMPs in the diagnosis of an intravestibular ILS.

Abstract
The chronic ear survey (CES) is a sensitive and disease specific quality of life (QoL) measurement tool in patients with chronic suppurative otitis media (CSOM). It is a 13-item survey that evaluates the frequency, duration and severity of problems associated with this disease. It is composed of three subscales that describe activity restrictions, symptoms and medical resource utilisation. Based on patient's answers, it is possible to obtain a score resulting in a scale ranging from 0 to 100; the highest indicates the best health, while the lowest denotes poor health. The questionnaire was originally created in English. The aim of this study is to validate the CES questionnaire in Italian (CES-I). Translation was made following international guidelines. The application follows the stages of translation from English to Italian and linguistic adaptation, and grammatical and idiomatic equivalence review. The CES-I and the Short Form Health Survey 36 (SF-36) questionnaires were administered to 54 patients with CSOM. A cross-sectional design was used to examine the internal consistency (Cronbach's alpha) and concurrent validity (Pearson's product moment correlation). To confirm the external validity of CES-I, Pearson correlation coefficient, considering the total score and single subscales of CES and the 8 scales of the SF-36, was calculated. Cronbach's alpha coefficient for internal consistency was 0.737. The intraclass correlation coefficient, measured through mixed effects, was 0.737 (95% CI: 0.600–0.835, p < 0.001) for average measures and 0.412 (95%CI: 0.273–0.559, p < 0.001) for individual measures. According to our results, CES-I is a reliable tool for evaluation of QoL in patients with CSOM among the Italian-speaking population.

Abstract
Objective The aim of this study is to evaluate the sensitivity parameters of the percentage of time the pH is <4 and >7, as well as the total number of laryngopharyngeal reflux episodes in 24 hours, in patients with suspected laryngopharyngeal reflux disease. Study Design Retrospective controlled study. Setting University hospital. Subjects and Methods The study was conducted on 46 patients with laryngopharyngeal reflux disease and 58 healthy controls. Patients and controls underwent 24 hours of dual-probe pH monitoring of the distal and cervical esophagus. Patients completed a Reflux Symptom Index questionnaire and underwent esophageal manometry. Data concerning the percentage of time the pH was <4 and >7 and the number of reflux episodes registered at the cervical esophagus were collected and evaluated. Results The percentage of time the pH is <4 and the number of laryngopharyngeal reflux episodes seem to be a reliable diagnostic laryngopharyngeal reflux criterion reaching satisfactory sensitivity (81% and 83%, respectively). Although the pH >7 parameter appeared statistically different between the 2 groups ( P < .001), the sensitivity of the test appeared to be poor (55%). Conclusion Our study demonstrates the importance of the absolute number of laryngopharyngeal reflux episodes in 24 hours in the diagnosis of patients with suspected laryngopharyngeal reflux, proposing it as a new diagnostic criterion.

Abstract
CONCLUSIONS Stapedotomy is, in our opinion, the technique of choice in stapes surgery. The precision of this technique allows clinicians to perform the surgical procedure in day surgery under local anesthesia. OBJECTIVES There is a strong emphasis on increasing the number of elective day surgery cases, especially in the patients' best interest, as it decreases the likelihood of late cancellation and hospital-acquired morbidity. A prospective study was performed to determine whether stapes surgery for otosclerosis could be performed safely in an outpatient setting. METHODS We present a series of stapes surgery cases for otosclerosis performed on a day-case basis. We performed a classic stapedotomy in 9 patients, a reverse classic step stapedotomy in 2 patients, a partial reverse classic step stapedotomy in 11 patients, and a hemi-stapedectomy in two patients. RESULTS Three of 24 patients (12.5%) treated with classic stapedotomy, 1 patient with partial reverse classic step stapedotomy, and 1 patient with hemi-stapedectomy were formally admitted to the hospital after surgery (length of stay, 23 h). The indications were vertigo (two patients) and asthenia (one patient). These patients were treated under general anesthesia. Two of these patients resided more than 250 km away from the hospital.

Abstract
OBJECTIVE The aim of this study was to investigate the possible correlation between otitis media with effusion, bad sucking habits and atypical swallowing in children affected by otitis media with effusion. METHODS 65 children, aged from 7 to 12 years, observed in the ENT Department of the "La Sapienza" University of Rome, were enrolled in the study group (group A). All children were affected by otitis media with effusion for more than 3 months. As control group, 60 healthy children, aged from 7 to 12 years were identified (group B). All the children underwent medical history, with evaluation of the sucking habits, ENT examination, tympanometry, orthodontic examination and evaluation of swallowing. In the orthodontic examination the variables analyzed were: maximum mouth opening, right and left mandibular lateral movements and mandibular protrusion. Atypical swallowing was considered to occur when lip activity produced strong tension in the perioral musculature, and/or the tip of the tongue was placed or pushed against the anterior teeth during swallowing. RESULTS In the group A, atypical swallowing was found in 33/65 subjects out of the 65 children (50.7%). In the control group (group B) 16/60 children (26.6%) showed atypical swallowing. Compared with group B, deleterious sucking habits were significantly higher (p<0.05) in the study group (28/65 vs. 12/60). In both the study and control group, deleterious sucking habits were present in almost all children with atypical swallowing (28/33 in group A and 12/16 in group B). CONCLUSIONS Our data suggest a correlation between otitis media with effusion, deleterious sucking habits and prevalence of atypical swallowing.

Abstract
OBJECTIVES To ascertain the prognostic role of endoglin (CD105)-assessed microvessel density (MVD) in patients older than 65 years with laryngeal squamous cell carcinoma (LSCC), and whether this MVD differed in the elderly patients from younger adult controls. DESIGN Retrospective clinicopathologic investigation. SETTING Academic tertiary referral center. PATIENTS Fifty-seven consecutive elderly patients with LSCC and 19 younger adult controls. MAIN OUTCOME MEASURE Image analysis of immunohistochemical reactions. RESULTS In LSCCs in elderly patients, N+ stage correlated with a shorter disease-free survival (DFS) (P < .001). A higher CD105-assessed MVD was associated with disease recurrence (P = .006). The DFS was shorter in elderly patients whose CD105 expression was greater than 9.6% than in patients whose CD105 expression was 9.6% or less (P = .001). Among the elderly patients with tumors staged as N0, a higher CD105-assessed MVD correlated with disease recurrence (P = .006) and a shorter DFS (P = .001). CD105-assessed MVD in LSCC occurring in elderly patients did not differ from the situation observed in younger adult controls (P = .74). CONCLUSIONS In LSCC occurring in elderly patients, CD105-assessed MVD may be a useful N-stage independent, angiogenic prognostic marker for pinpointing: (1) patients at higher risk of disease recurrence; and (2) patients with N0 tumors at higher risk of early recurrence, who may benefit from more aggressive therapy.

Abstract
Vertigo and dizziness are common conditions in the adult population that can be rarely seen during childhood; only a few articles describing vertigo in children can be found in literature. Although many causes of vertigo in adulthood occur also in childhood, their frequency may be different. A typical example is benign paroxysmal positional vertigo, the most common peripheral vestibular disorder in adults, which occurs quite uncommonly in children. Furthermore, many common diseases causing vertigo in children may be unique for this population, such as benign paroxysmal vertigo (BPV) of childhood. At present, BPV is defined as a migraine's equivalent, a precursor of migraine or a periodic syndrome of childhood. The International Headache Society also studied this form of vertigo and included the Benign Paroxysmal Vertigo in section 1.3.3. of the International Classification of Headaches (ICHD-2). The present review analyzes recent patho-physiological and clinical evidences regarding idiopathic BPV in children.

Abstract
CONCLUSIONS The absence of audiologic side effects highlights the reduced trauma of the piezoelectric cut, demonstrates the superiority of the Piezosurgery device in terms of safety and protection of anatomical structures and confirms its applicability in all the otologic techniques tested. OBJECTIVES The aim of the present study was to estimate the effect of Piezosurgery on the cochlea and in particular on the cochlear outer hair cells. PATIENTS AND METHODS We selected 60 patients with a history of otologic surgery with Piezosurgery. Before and 6 months after surgery, all the patients underwent the following instrumental examinations: pure-tone audiometry, tympanometry, transient evoked otoacoustic emissions (TEOAEs), distortion product otoacoustic emissions (DPOAEs) and auditory brainstem response (ABR). RESULTS Piezosurgery showed its safety on the inner ear and in particular on the cochlear outer hair cells: for each instrumental examination (pure-tone audiometry, tympanometry, TEOAE, DPOAEs and ABR), no patients presented postoperative worsening.

Abstract
The main objective of this study was to determine reliability, validity, and reproducibility of the Italian version of the Tinnitus Handicap Inventory (THI) self-administered questionnaire aimed at evaluating the impact of tinnitus on the quality of life of subjects affected by this symptom. The questionnaire was presented to a sample of 443 subjects (285 men and 158 women; ages 19-86; mean age, 53) who were referred to our Tinnitus Centre in Rome and came from the entire national territory. All subjects reported as their main problem a tinnitus that had persisted for at least 6 months. Statistical analysis carried out on THI questionnaire results showed high internal consistency and reliability for the total scale (Cronbach's alpha = .94). Despite the poor number of items, the THI proved useful for the functional scale (0.86), the emotional scale (0.89), and the catastrophic scale (0.75).

Abstract
PURPOSE Rhinoscleroma is a rare, chronic, granulomatous disorder of the upper airways. This disease presents some etiopathogenetic aspects that are not yet clear. Infection by Klebsiella rhinoscleromatis is fundamental for the onset of the disease, but it is impossible to reproduce rhinoscleroma experimentally only via infection with the bacteria both in man and in animals. Furthermore, this disease mainly affects blood-related people and occurs in certain geographic areas. In this context, we present a study that brings to light some of the quantitative abnormalities of the lymphocyte subsets. MATERIALS AND METHODS The study group consisted of 5 patients with rhinoscleroma. The following parameters were studied for each patient: clinical manifestations, histologic examinations, number of leukocytes, lymphocytes, and lymphocyte subsets. RESULTS In all patients, we noted the following: There was a relative reduction of the CD4+ cells, an absolute increase of the CD8+ cells, and an inversion of the CD4+/CD8+ ratio. There was an absolute increase of the CD56+ cells and cytotoxic cells that coexpress CD8+CD56+ antigens. There was a relative reduction of the CD3+ cells, and the CD19+ cells tended to show an ambiguous behavioral pattern. CONCLUSION We believe that K. rhinoscleromatis does not play a major role in the etiopathogenesis of rhinoscleroma. However, we do believe that the anomalous behavior of the immune system can favor rhinoscleroma.

Abstract
The aim of this study was to compare the efficacy and the safety of a short oral ribosomal immunotherapy (Immucytal) in the prevention of chronic otitis media in children. Seventy-two patients were enrolled in this study, 41 males and 31 females, aged between 6 and 14 years, with an history of recurrent otitis media. Patients were randomised to receive Immucytal (group A) or placebo (group B) according to the following protocol: one tablet daily in the morning 8 days per month for three consecutive months. Immucytal and placebo were identical in shape and size, in order to maintain double-blind conditions. The efficacy parameters were (evaluated before, at the end and 6 months after the beginning of the therapy): clinical score; changes in immunological parameters; patient's parents assessment of symptoms on a scale from 0 (much worse) to 4 (much improved) and hearing tests. Patients of group A, had an improvement of clinical items measured, serum concentrations of immunoglobulins, subjective patient's parents assessment of symptoms and hearing tests. For all evaluations, a significant difference between treatment groups was found. Using this dosage and posology (shorter than others) the beneficial effects of Immucytal were maintained until the end of the 6-month study period.

Abstract
For over a century, surgical management of lower turbinate hypertrophy has given rise to much discussion. Aim of the present investigation was to establish, by means of the analysis of a large patient population, the efficacy and reproducibility of high frequency surgery in the treatment of this condition. A total of 1689 non-allergic patients with nasal obstruction, presenting hypertrophy of the lower turbinates, were submitted, under local anaesthesia, to turbinates decongestion using a high frequency instrumental unit with a bipolar terminal electrode. Efficacy of the procedure was evaluated on the basis of objective examination, results of questionnaires, active anterior rhinomanometry and mucociliar transport time. Results revealed a reduction of hypertrophy, an improvement in symptoms, a reduction in nasal resistances and an improvement of mucociliar transport time. The large patient population, low post-operative complication rate and the good patient compliance, due also to the fact that no haemostatic procedure is necessary, would suggest that this method is particularly valid, effective and safe for the treatment of hypertrophy of the lower turbinates.

Abstract
Malignant schwannoma is an aggressive tumor that carries a poor prognosis despite wide excision, chemotherapy, and radiotherapy. Malignant schwannoma of the parapharyngeal space is an uncommon finding; to our knowledge, only four cases have been described in the literature during the past 30 years, and only one of them involved a patient who had clinical evidence of neurofibromatosis type 1. In this article, we describe a new case of malignant schwannoma of the parapharyngeal space in a patient who had clinical evidence of neurofibromatosis type 1. Following resection of the tumor and a total parotidectomy, the diagnosis was made on the basis of histology and immunohistochemistry. The patient underwent postoperative chemotherapy with carboplatin and UP16. However, 5 months following surgery, the tumor recurred and metastasized. The patient was then placed on a different polychemotherapeutic regimen, which was made up of 3 g/m2 of ifosfamide, 1.5 mg/m2 of vincristine, and 1.5 mg/m2 of doxorubicin (IVA2 protocol). The IVA2 regimen slowed tumor growth, but 13 months after the initiation of therapy, the patient died of neoplastic cachexia. Although chemotherapy is generally ineffective in most cases of malignant schwannoma, we did experience some positive results with the IVA2 protocol. Therefore, we recommend that this combination be considered as a first-line adjuvant therapy following surgery or as a first-line therapy for patients with inoperable tumors.

Abstract
BACKGROUND Gas-containing brain abscesses are very rare. Two mechanisms may be responsible for the presence of intracavitary gas: bacterial fermentation or penetration through an abnormal communication between the exterior and the intracranium. The need to search for this potential communication is considered an indication for open surgery. We report the case of a surgically treated gas-containing brain abscess originating from an undiagnosed chronic otitis media. CASE DESCRIPTION A 54-year-old man developed acute neurologic deterioration, becoming comatose within 24 hours. A contrast-enhanced computed tomography (CT) scan disclosed a gas-containing cystic mass in the right temporal lobe. Urgent surgical decompression revealed the presence of an abscess, which was excised. During the same surgery, we performed a radical mastoidectomy, removing a previously undiagnosed attic cholesteatoma. Neither procedure revealed a discontinuity of the floor of the middle cranial fossa. Cultures grew a mixed flora. Antibiotics were administered for 6 weeks. The patient made a complete neurologic recovery. CONCLUSION This report demonstrates that otogenic brain abscesses may contain gas due to fermentation of nonclostridial bacteria.

Abstract
Distortion product otoacoustic emissions (DPOAEs) are an objective, non-invasive measure for evaluating outer hair cell (OHC) activity. In this study DPOAEs were measured in 70 patients affected by Meniere's disease (MD). In addition 58 out of 70 patients performed both an audiometric threshold evaluation pre- and postglycerol administration (i.e. glycerol test) and DPOAEs pre- and post-osmotic drug assumption. The purpose of this combined form of testing was to explore the effects of glycerol on the active non-linear mechanisms of the cochlea. More than 60% of the ears with MD emitted DPOAEs despite the presence of an average hearing threshold level above 40 dB (HTL). Changes in the DPOAE baseline measures were observed in 32.4% of cases after glycerol administration. Patients were divided in four groups according to the different pattern of DPOAEs shown after the glycerol test. In particular, three-quarters of cases showed a significant increase in DPOAE amplitude, one-quarter of patients, who initially did not express DPOAEs, eventually did after intake of the osmotic agent, while no decreased DPOAEs were observed in these series. The different expressions of DPOAEs should be associated with the evolutive phases of MD. In addiction, elucidation of the relationship between DPOAEs and the stages of MD was an outcome of this test.

Abstract
Distortion Product Otoacoustic Emissions (DPOAEs) shows a vulnerability to acoustic overstimulation that is easily detectable by changes in amplitude, frequency distribution and time course. The frequency-specific changes in DPOAE provide more information than the more general changes in click evoked otoacoustic emissions. In this work five anesthetized guinea pigs were examined for changes DPOAE after exposure to pure tones. The noise was a 110 dB SPL pure tones for 45 minutes and the fatiguing tone centered on the geometric mean (GM) of primaries or 2/3 of GM. The most measurable effects were obtained in the latter conditions. The main DP level reduction lasts about one hour after exposure, but the complete recovery is observable only after 24 hours. The frequency distribution of fatiguing effects on the DP- audiogram shows a remarkable fine tuning and a pattern like a low-pass filter. After four hours, in one guinea pig, it is observable an enhancement of the DP amplitude, compared to the pre-exposure level; in another guinea pig, a second overstimulation produced a more extensive and time-lasting effects than the first exposure.

Abstract
Contralateral ear pathologies are frequently found in patients suffering from acquired cholesteatoma. A retrospective study was performed on 85 pediatric patients and 105 adults surgically treated for acquired middle ear cholesteatoma. All the patients were checked and the otomicroscopic picture photographed and compared in an attempt to gain insight into the pathogenesis and clinical indications by comparing two samplings from different age groups. In both groups the frequency of pathological contralateral ear manifestations was higher than found in the normal population. Similar results were obtained in the two groups and indicate that the same mechanisms come into play in both ears, starting at infancy. The finding of a particularly common association between cholesteatoma and contralateral retraction pockets with sinus cholesteatoma or pars tensa in the pediatric group appears to confirm that tubal dysfunction plays a pathogenic role in the genesis of cholesteatoma. From the practical point of view, systematic preventative measurement of the contralateral ear can lead to a reduction in major surgery and can affect the choice between open or closed tympanoplasty. Moreover, it may also condition the precision and length of the follow-up.

Abstract
There is indication that middle ear pathologies can affect otoacoustic emissions (OAE) to varying degrees. In fact, since acoustic emissions are recorded in the outer ear duct, the energy transfer mechanisms both up and downstream of the middle ear must be intact. OAE distortion products (DP) enable one to analyze cochlear response by frequency and to verify the retrograde response as a function of frequency. In the present work this method was used to test otosclerosis patients. A group of 45 patients with otosclerosis was tested to determine whether the OAE-DP could be identified and measured. Subsequently the characteristics of these DPs were analyzed in a group of 18 subjects who had previously undergone stapedectomy. All the results obtained were compared with those from a control group of normal hearing subjects with normal emissions and free of any E.N.T. pathology. In approximately half of the cases (53%) in the otosclerosis patient group it was possible to detect clearly evident DPs. Obviously, the DP-Gram differed greatly and average amplitude was lower than those found in normal subjects. Indeed, there was no signal at all at the lower and middle frequencies reflecting a hearing loss typical of cases of otosclerosis. Most (58%) of the otosclerosis patients who had successfully undergone stapedectomy recorded valid DPs. The DP-Gram frequency range was much broader (750-4000 Hz) than in those who had not undergone surgery. Moreover the lower and mid frequency amplitudes were significantly better. The data obtained are quite encouraging and suggest that DP should be studied in depth in patients with otosclerosis.

Abstract
Menière's disease appears with the classic triad of symptoms in about 1/3 of cases so that, on the whole, diagnosis is delayed until full symptomatology develops. Spontaneous reversibility and effective control, if any, of the disease mechanism are limited to the beginning phases and thus it seems appropriate focus attention on the earliest symptoms. Unfortunately, the pre-diagnosis period is poorly known and, for this reason, we decided to investigate it in our series. The purposes of this research were: 1) to estimate the prevalence of isolated symptoms in subjects successively found to be menieric; 2) to make a clinical outline of the pre-diagnosis period; 3) to investigate the relationship between the pre-diagnosis period and the post-diagnosis disease course. From a group of 216 Menière's patients (diagnosed according to the 1985 AAOO criteria), 170 were selected on the basis of availability of audiometric and clinical data pertaining to the pre- and post-diagnosis disease course. Isolated symptoms in the pre-diagnosis period were found in 107/170 subjects (63%). The nature of the symptoms was cochlear (71.9%), vestibular (22.4%) and mixed (5.6%). In the largest group of patients (41 cases), the pre-diagnosis period lasted from 2 to 5 years. This period was shorter in the cases with mixed symptoms in comparison with patients suffering from either cochlear or vestibular symptoms. Between the 2nd and 5th year following diagnosis, hearing was seen to deteriorate more significantly in patients with a history of isolated cochlear symptoms. Furthermore, patients whose first disturbances were of cochlear origin suffer significantly shorter vertigo attacks.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Distortion Product Otoacoustic Emissions (DPOAEs) are elicited by simultaneous application of two tones to the ear canal. These emissions are a result of nonlinear mechanical characteristics of the cochlea at a specific point and have a precise mathematical relation with the frequencies of the two eliciting primary tones f1 and f2. This frequency-selective property of DPOAEs suggests that they should be regarded as useful monitor of localized cochlear function at any predetermined frequency. The present study was designed to investigate DPOAEs in patients with Menière's disease. DPOAEs were recorded before and after glycerol administration to verify if the fluctuation of the hearing threshold induced by this hyperosmotic agent causes selective changes in the activity of the outer hair cells. DPOAEs were present in patients in which the mean duration of the disease was shorter compared to those patients without measurable DPOAEs. An improvement of DPOAEs after glycerol intatte was observed in a half of our cases. The improvement of DPOAEs does not appear to be brought about by modifications of the auditory threshold induced by glycerol.

Abstract
When vertigo attacks and balance disorders stop, menieric patients are generally considered recovered although they complain of more or less severe sensorineural hearing loss. As far as a true clinical recovery is concerned, the Authors think that it should correspond not only to absence of vertiginous spells but even to a long lasting normal and stable hearing level. On the basics of this presumption, they select the files of 7/207 patients showing complete recovery since not less than 8 years. Age at the onset of the disease, associated disease, isolated symptoms before the appearance of the classic triade, age at the first attack, total number of crises, length of active period of the disease, maximum hearing loss, shape of audiometric tracing are all analyzed. Healed patients are characterized by a smooth evolution, which reverses in the very first phases of the disease, as well as by the following: 1) absence of head injury and viral labyrinthitis in clinical history; 2) onset of disease with complete symptomatology; 3) slight hearing loss and up-sloping audiometric configuration; 4) few attacks of vertigo (less than 30) lasting no longer than 12 hours; 5) active period of disease not exceeding 18 months. Recovery from Ménière's disease seems possible as long as labyrinth lesions are not stabilized.

Abstract
Numerous epidemiologic investigations have been conducted regarding the incidence of Menière's disease, but the values obtained for different countries vary greatly. This can be attributed to the fact that different criteria have been applied in defining Menière's disease. The objective of this study was to evaluate the incidence and prevalence of Menière's disease in Italy following the American Academy of Ophthalmology and Otolaryngology guidelines. A total of 111 cases with Menière's disease were diagnosed in a district of southeastern Latium over a 13-year period, with an incidence of 82 per 10(6). A figure 3.4 times greater was found in hospital personnel, thus showing that a greater availability of medical facilities increases the number of diagnoses. Sex was found not to be a determining factor. The authors suggest that the incidence reported in this paper is an underestimate and that the actual one remains undetermined, but probably higher than generally believed.

Abstract
The effect of acetazolamide was assessed in 25 patients with Menière's disease. During the test session hearing threshold and plasmatic osmolality were monitored along with fluctuations in hearing loss, fullness, tinnitus and balance. A single, 250 mg dose of acetazolamide was administered to all patients via os early in the morning on an empty stomach. Hearing was tested prior to administration and every hour for five hours thereafter. Plasmatic osmolality was also assessed during the same session. In 52% of this group an improvement in the threshold was seen. The greatest shift was observed two hours after administration of acetazolamide at 250 Hz, whereas the smallest threshold shift corresponded to 2000 Hz. In all cases, plasmatic osmolality remained constant throughout. Of the patients 44% presented an improvement of all or one of the symptoms: hearing loss, tinnitus, fullness, balance. The data were compared with data obtained for a control group (9 patients) which received a placebo while following the same testing criteria. The results of this study suggest that acetazolamide can have a positive effect on endolymphatic hydrops. It should be stressed, therefore, that acetazolamide could be introduced in the diagnostic and therapeutic strategies applied in Menière's disease.

Abstract
The object of the present paper was to investigate the presence of other diseases in patients suffering from Menière's disease and to identify any common etiopathogenetic factors. In a group of 100 patients there was a high incidence of three pathological associations: 1) anxiety and depression; 2) dyspepsia; and 3) vasomotor headache. The percentages were then compared with the data found in the literature and with the non menieric population. The association of dyspepsia proved statistically significant. The relationship between anxiety and vasomotor headache remains suspect while awaiting more precise definition of these diseases and findings more comparable with the total population.

Abstract
The purpose of this study was to evaluate the incidence and the prognosis of patients with recurrences of Bell's palsy. Yanagihara's classification of recurrent palsies was used, and all palsies were separated into five different types. A total of 304 patients with Bell's palsy were examined. The recurrent ipsilateral attacks (i.e., the unilateral recurrent palsies) showed a worse prognosis when compared with the non-recurrent palsies. In contrast, the recurrent attacks involving the contralateral facial nerve (bilateral alternating palsies) presented a better facial recovery. In reviewing the recurrent cases, the stapedial reflex demonstrated no prognostic value. Our results suggest that in presenting data of Bell's palsy it is advisable to differentiate the recurrences from the common (non-recurrent) palsies.

Abstract
The object of this paper was to study the brain stem evoked response in 20 patients suffering from chronic renal failure and having haemodialysis, and to evaluate the effects of this treatment. A further 5 successful renal transplant patients were investigated to analyse the evolution of the brain stem conduction when the metabolic abnormality is removed. In the first group, the responses were minimally abnormal in 30% of cases before the dialysis. The dialysis session showed an improvement of the brain stem conduction. This variation was temporary and, 24 hours following the dialysis treatment, the patients showed the pathological values observed before the dialysis. The results of the successful transplanted patients were consistent with the data obtained in the dialysis group. Before transplantation the nerve impulse conduction was found to be abnormal in 3 subjects. These abnormalities disappeared completely after successful transplantation. These results support the view of those who favour the use of evoked potentials to follow the status of the central nervous system in uraemic patients.

Abstract
In Bell's palsy the stapedial reflex may be affected or not. The object of this paper was to study the evolution of the stapedial reflex and its latency pattern during the first weeks of paralysis and to correlate these parameters with the evolution of the disease. One hundred and thirty-three patients with Bell's palsy were evaluated, and the patients could be divided into 3 groups. Group 1 was composed of subjects in whom the stapedial reflex was present in the first week of paralysis and complete recovery of facial function occurred in 30-60 days. In group 2 the stapedial reflex reappeared between the eighth and thirty-fifth days post-onset and facial function recovered within 150 days. In group 3, the stapedial reflex reappeared between the thirty-sixth and seventieth day and some paralysis was still present after 1 year. These results suggest that the reflex is important for prognostic purposes.

Abstract
The authors give an account of the outcome of research done in the Allergo-Immunological Centre of the IInd ENT Division of Rome University, carried out among 210 children who were affected by nasal atopy. Particular stress was placed on the involvement of the nasopharyngo-tubal system. The age of the children ranged from 2-12 years and they underwent: 1) ENT visit; 2) allergy tests; 3) anterior rhinorheomanometry; 4) tubal function tests; 5) mucociliary clearance time; 6) X-ray examination of paranasal sinuses. The results revealed that the most frequent symptom in these children is rhinitis, whatever the allergic sensitization was. The forms of atopy which manifested themselves by chronical allergic patients (D.Pt. and P.O.) were the cause of: 1. asthmatic-type syndromes; 2. early onset of atopic symptoms around 4-7 years of age (9-10 years in the seasonal forms); 3. greater degree of extrinsic rhinitis with edema of the turbinates - the first step towards a polypoid degeneration of such subjects; 4. tubal functional deficit (60% of subjects allergic to P.O. and 50% allergic to D.Pt whereas only 27% are found in the seasonal forms); 5. mucociliary clearance linked directly with the length of disease; involvement of the paranasal sinuses (53/61 patients allergic to D.Pt., 9/28 allergic to P.O., 9/56 allergic to Graminacee). Furthermore the nasal patency was more insufficient in patients affected by the chronical forms of the atopy. In the light of these results the authors advocate focus attention on the significance of an early diagnosis of nasal atopy in children and the need for interdisciplinary collaboration among specialists.
