The effect of MemoVigor 2 on recent-onset idiopathic tinnitus: a randomized double-blind placebo-controlled clinical trial.

Background: Tinnitus is a common symptom associated with the conscious perception of sound in the absence of a corresponding external or internal sound source, which can severely impact quality of life. Because of the current limited understanding of the precise pathophysiological mechanism of idiopathic tinnitus, no curable treatment has been attained yet. A food supplement trading as MemoVigor 2, which contains a combination of therapeutic ingredients with mainly antioxidant activity, has been used in the treatment of tinnitus. The objective of our study was to evaluate the effectiveness of MemoVigor 2 in the treatment of recent-onset idiopathic tinnitus. Methods: In a prospective single-centre randomized, double-blind, placebo-controlled clinical trial we studied 204 patients with idiopathic tinnitus divided into two groups: 104 patients who received MemoVigor 2 and 100 patients treated with placebo. To evaluate changes in tinnitus we used (1) audiometry/tympanometry; (2) specific measures of tinnitus perception, including tinnitus pitch, loudness at tinnitus pitch, loudness at 1 kHz, minimum masking level, and residual inhibition; (3) questionnaires of tinnitus handicap inventory, mini tinnitus questionnaire and patients' global impression of change. All patients underwent this test battery at the beginning of the study and in a repeat post-3-month session. Results: All tinnitus measures, including pitch, loudness, minimum masking level and residual inhibition improved significantly in the intervention group. Most of these measures improved in the placebo group too, but in a lesser degree. All questionnaire scores diminished significantly in both groups, but the degree of decrease was greater in the intervention group. The participants' tinnitus outcome reported after treatment using the patients' global impression of change score differed significantly between the two groups, with greater improvement observed in the intervention group. Conclusion: We found that the use of MemoVigor 2 improved recent-onset tinnitus, as proved by a set of tests performed for its evaluation, including audiometric measures, specific measures of tinnitus perception and tinnitus questionnaires. Tinnitus in the placebo group improved too, but to a lesser degree. Clinical Trial Registration: isrctn.com, Identifier ISRCTN16025480.

The Clinical Significance of Pollen and Fungi Concentrations for Allergic Rhinitis: A Three-Year Study.

INTRODUCTION: The relationship between disease severity and exposure to allergens in allergic rhinitis (AR) patients is not fully clarified presently. We aimed to detect the correlation between airborne pollen and fungi concentrations in a Mediterranean region with symptom scores. METHODS: A total of 98 patients suffering from AR rated their symptoms at the time of exacerbation using the Total 5 Symptoms Score (T5SS) and the Visual Analogue Scale (VAS). Patients' quality of life (QoL) was estimated by using either disease-specific (Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) and mini-RQLQ) or generic (Short-Form 36 (SF-36) and Beck Depression Inventory (BDI)) questionnaires. All patients' responses were correlated with aerobiological data. Skin prick tests (SPTs) were used to detect sensitivities to the most common registered pollen and fungi species. RESULTS: A significant positive correlation between total pollen and fungi counts and disease-specific questionnaires was found only for the RQLQ. Accordingly, a significant positive correlation was found between total pollen and fungi counts and T5SS (r = 0.655, p = 0.021), with breathing (r = 0.620, p = 0.032) and sneezing (r = 0.660, p = 0.020) being strongly affected. Moreover, a tendency toward a higher VAS score was found as total pollen and fungi counts increased (r = 0.523, p = 0.081). CONCLUSION: We found a significant correlation between patients' symptoms and pollen and fungal air concentrations. Our results emphasize the clinical significance of pollen and fungi maps in everyday clinical practice.

Three-year pollen and fungi calendar in a Mediterranean region of the Northeast Greece.

INTRODUCTION AND OBJECTIVES: Pollen calendars have been proved clinically important in allergic disease management, as differences in airborne allergens exist not only between different countries but also between regions of the same country as well. This study aims to provide new data regarding the atmospheric pollen and fungi content of a Mediterranean region (Western Thrace/North-East Greece) and discuss seasonal trends, differences in pollen grains and fungi spores' circulation over the years, and correlations with climate parameters. MATERIAL AND METHODS: A 7-day continuously running volumetric trap was used to collect circulating pollen grains and fungi spores. Pollen taxa and fungi were characterized by standard protocols and counted as grains /m3 and average total grains and spores. The primary allergenic pollen season was discovered, and their 10-day averages were measured over time. Correlations with temperature, rain, and humidity were assessed by single linear regression analysis. RESULTS: Pollen grains from nine pollen families were identified, including five arboreal, two nonarboreal taxa, and spores from two fungi species. The three most prevalent taxa were Oleaceae, Poaceae, Pinaceae, and Cladosporium in the fungi. Peak pollen concentrations were detected during April and May, with daily averages exceeding 170 grains/m3. Poaceae presented the longest pollen season of 342 days and Oleaceae the shortest, extending to only 110 days, during the 3years. Cladosporium was the fungus with the highest spore concentration (180,129.9 spores) compared with Alternaria (28,026.1 spores). Correlations with meteorological parameters showed variable associations among different taxa, with rainfall and relative humidity being the most significant determinants. CONCLUSION: In this study, the pollenic and fungal spectrum of a Mediterranean region and information that can be proved clinically significant for the appropriate diagnostic and therapeutic approach of allergic patients was presented.

Validation of the Greek Version of Tinnitus Handicap Inventory.

PURPOSE: The purpose of this study was to validate the Greek version of the Tinnitus Handicap Inventory. METHOD: Eighty-six adult patients with chronic tinnitus participated in the study. Sociodemographic data and medical history were recorded during the interview. The patients underwent audiological examination and they were asked to fill in three questionnaires: the Greek version of the THI (THI-GR), the Greek version of the State-Trait Anxiety Inventory (STAI) and the brief Tinnitus Severity Scale Questionnaire (TSSQ). RESULTS: The THI-GR showed good internal consistency, comparable to the original version. Cronbach's alpha was equal to 0.92, which suggests a robust reliability. All THI-GR subscales along with total score were significantly and positively correlated with the TSSQ grade and the audiogram results indicating the existence of convergent validity. Furthermore, THI-GR's subscales were significantly correlated with both State and Trait subscales, which indicates a correlation between tinnitus and stress. CONCLUSIONS: This study highlighted the high reliability and validity of the THI-GR as a self-report measure for the evaluation of tinnitus-related annoyance and psychological distress in clinical practice.

Benign Paroxysmal Positional Vertigo Secondary to Mild Head Trauma.

OBJECTIVES: We studied the clinical characteristics, nystagmographic findings, and treatment outcome of a group of patients with benign paroxysmal positional vertigo (BPPV) secondary to mild head trauma and compared them with a group of patients with idiopathic BPPV. METHODS: The medical records of 33 patients with BPPV associated with mild head trauma were reviewed. Data of a complete otolaryngological, audiological, neurotologic, and imaging evaluation were available for all patients. Three hundred and twenty patients with idiopathic BPPV were used as a control group. RESULTS: The patients with BPPV secondary to mild head trauma presented the following features, in which they differed from the patients with idiopathic BPPV: (1) lower mean age, with more intense symptoms; (2) increased rate of horizontal and anterior semicircular canal involvement and frequent multiple canal and bilateral involvement; (3) greater incidence of canal paresis and presence of spontaneous nystagmus; (4) poorer treatment results, attributed mainly to coexisting canal paresis in many patients, and higher rate of recurrence. CONCLUSIONS: Benign paroxysmal positional vertigo associated with mild head trauma differs from idiopathic BPPV in terms of several epidemiological and clinical features; it responds less effectively to treatment and is prone to recurrence.

Ocular vestibular-evoked myogenic potentials using air-conducted sound: test parameters and normative data in healthy children; effect of body position on threshold.

In the present prospective study, we both investigated positioning techniques for the enhancement of oVEMP procedures and the viability of oVEMP testing in a healthy children population. A total of 41 healthy children were enrolled in this study. 21 were boys and 20 were girls, with their ages ranging from 4 to 16 years. All children underwent audiometry and tympanometry prior to oVEMP test in upright and supine position. All subjects had normal hearing. The procedure was well tolerated by all children. Typical biphasic oVEMPs presented in 97.56 % in upright position and 90.25 % in the supine position. No statistically significant difference could be found concerning which position elicits the best or worst responses. However, a trend towards the supine position was noticed. It may be concluded that oVEMP test proved to be a well-tolerated examination of the vestibular system in children aged above 4 years old. Our results did not show a statistical difference on the oVEMP thresholds between the two body positions. However, further larger studies are needed to confirm these findings.

Predictors of quality of life improvement in allergic rhinitis patients after sublingual immunotherapy.

OBJECTIVES: Sublingual immunotherapy (SLIT) has been described as a significant intervention in the treatment of allergic rhinitis (AR). However, factors that may predict treatment outcomes with respect to quality of life (QoL) results and mainly the role of olfactory function are still being underestimated. In this study, we investigated determinants that best predict treatment outcomes for QoL, exploring mainly the role of olfaction. METHODS: One hundred forty-five patients following SLIT, 45 placebo-controls, and 48 healthy subjects were studied. Olfactory function was objectively evaluated using "Sniffin' Sticks" test pre- and post-cessation of SLIT. Three categories of validated QoL questionnaires were filled out by all subjects: questionnaire specific for olfaction (Questionnaire of Olfactory Deficits), questionnaires for assessing psychology (Beck Depression Inventory, Zung Depression Scale, State & Trait Anxiety Inventory), general Short Form-36 health survey. RESULTS: Statistically significant improvement of olfactory function by 11.1% and of all QoL questionnaires results (all P<.001) was observed on final evaluation. Anosmia, asthma history, and the severity of symptoms-expressed by the Total Symptoms Score-were proven independent determinants of clinically significant improvement in patients' QoL. CONCLUSIONS: Several factors were found that may predict QoL outcomes in AR patients following SLIT.

Demographic correlates of anxiety and depression symptoms in chronic sinonasal diseases.

OBJECTIVES: To explore mental health of patients with olfactory loss due to chronic sinonasal diseases and investigate the effects of age-, gender-, and socio-economic variables on anxiety and depression symptoms. METHODOLOGY: One hundred and eight patients (62 males; mean age: 39.78 ± 16.11 years), suffering from olfactory impairment due to chronic rhinosinusitis and allergic rhinitis and 30 healthy subjects (16 males; mean age, 37.03 ± 13.09 years) were studied. Olfactory function was evaluated using "Sniffin' Sticks" test. All patients completed four validated questionnaires specific for assessing anxiety and depression (Zung Anxiety Scale, State-Trait Anxiety Inventory-STAI, Zung Depression Scale, and Beck Depression Inventory-BDI). RESULTS: We found significantly more severe anxiety and depression symptoms in anosmic (all p < 0.001) and hyposmic patients compared to healthy controls. No significant differences were observed between normosmic patients and controls. Scores in all psychological measures were significantly higher in elderly and female patients as well as in low, compared to high, socio-economic status patients. No significant differences were found between low and medium socio-economic level. CONCLUSIONS: Olfactory loss in chronic sinonasal diseases was found to be associated with anxiety and depression symptoms. Moreover, anxiety was correlated with depression. With regard to patients' demographics, female gender and low socioeconomic status proved to be independently correlated with anxiety and depression levels.

Benign paroxysmal positional vertigo secondary to vestibular neuritis.

The aim of this study was to present the demographic, pathogenetic and clinical features of benign paroxysmal positional vertigo (BPPV) secondary to vestibular neuritis (VN). The medical records of 22 patients, who presented with BPPV within 12 weeks after the onset of VN, were reviewed. Data of a complete otolaryngological, audiological, neurotologic and imaging evaluation were available for all patients. Two hundred and eighty-four patients with idiopathic BPPV were used as a control group. The patients with BPPV secondary to VN presented the following features, in which they differed from the patients with idiopathic BPPV: (1) a lower mean age; (2) involvement of the posterior semicircular canal; (3) presence of canal weakness; (4) more therapeutic sessions needed for cure and a higher rate of recurrence. It may be, thus, concluded that BPPV associated with VN differs from idiopathic BPPV in regard to several epidemiological and clinical features, it responds less effectively to treatment and may follow a protracted course, having a tendency for recurrence.

Predictors of quality of life outcomes in chronic rhinosinusitis after sinus surgery.

The predictive value of olfaction for quality of life (QoL) recovery after endoscopic sinus surgery (ESS) in chronic rhinosinusitis (CRS) is still underestimated. The aim of this study was to explore the proportion of patients suffering from CRS who experience clinically significant QoL improvement after ESS and identify pre-operative clinical phenotypes that best predict surgical outcomes for QoL, focusing mainly on the role of patients' olfaction. One hundred eleven patients following ESS for CRS and 48 healthy subjects were studied. Olfactory function was expressed by the combined "Threshold Discrimination Identification" score using "Sniffin' sticks" test pre-treatment and 12 months after treatment. All subjects completed validated, widely used QoL questionnaires, specific for olfaction (Questionnaire of Olfactory Deficits: QOD), for assessing psychology (Beck Depression Inventory: BDI) and for general health (Short Form-36: SF-36). Statistically significant improvement of olfactory function by 41.8% and of all QoL questionnaires scores (all p < 0.001) was observed on the 12-month follow-up examination. Clinically significant improvement for QoL was measured in a proportion of 56.8% of patients on QOD, 64.9% on SF-36 and 49.5% on BDI scales results. Although olfactory dysfunction, nasal polyps, female gender, high socio-economic status and non-smoking habits were significantly associated with better QoL results, multivariate logistic regression analysis revealed that only olfactory dysfunction and nasal polyps were independent predictors significantly associated with higher likelihood of clinically significant improvement in all QoL questionnaire results. Olfactory dysfunction and nasal polyps were independent pre-operative predictors for surgical outcomes with regard to QoL results.

A longitudinal study of changes in distortion-product otoacoustic emissions and pure-tone thresholds in an industrial setting.

In a longitudinal study of 76 noise-exposed industrial workers, 34 (68 ears) of them were available for final evaluation after 9 years of observation. Distortion-product otoacoustic emissions (DP) at 65/55 dB SPL and pure-tone audiometry were used to detect noise-induced inner ear changes. Repeated measures analyses of variance were made on the subjects and in a control group, whereas significant threshold shifts (STS) and significant emission shifts (SES) were calculated. Both hearing thresholds and DP showed a high-frequency deterioration, but there was absence of statistical correlation between elevation of hearing thresholds and decrease of DP. There was no clear pattern between individual changes in audiometric thresholds and DP, and all combinations were present: ears with only STS, ears with only SES, ears with both STS and SES and ears with absence of STS and SES. Audiometric changes were maximal at 4 and 6 kHz and DP changes at 2 and 3 kHz. Since significant individual emission changes do not necessarily follow the same pattern as the group-averaged results, the use of DP for monitoring of individual subjects is not advised. However, its use in conjunction with audiometry in hearing conservation programs is highly recommended.

Subcutaneous emphysema and pneumomediastinum after tonsillectomy.

Cervicofacial subcutaneous emphysema is a rare complication of tonsillectomy that often resolves spontaneously but may progress to obstruct upper airways or spread to the thorax causing pneumomediastinum or pneumothorax. The mechanisms by which subcutaneous emphysema and pneumomediastinum may develop after tonsillectomy are poorly understood. A case of a 21-year-old female undergoing routine adenotonsillectomy, who developed cervicofacial emphysema and pneumomediastinum, is presented. Possible pathogenetic mechanisms and treatment options are discussed.

Influence of cochlear implantation on the vestibular function.

The aim of the present study was to examine the influence of cochlear implantation on vestibular function. The function of the horizontal semicircular canal, the saccular function, and the incidence of vestibular symptoms were assessed before and after cochlear implantation. Twenty unilaterally cochlear implant patients were evaluated preoperatively, 1 and 6 months postoperatively, with caloric testing with electronystagmography (ENG) recordings and vestibular evoked myogenic potentials (VEMP) testing. A medical history was taken from every subject, noting the presence or absence of vertigo before and after the operation. A possible correlation between the appearance of postoperative vertigo and age, sex, implant side, preoperative caloric results and VEMP status, and postoperatively recorded changes in caloric and VEMP testing was also investigated. A statistically significant difference was found in the percentages of canal paresis (p = 0.01) and the percentages of VEMP waveform absence (p = 0.002) between the repeated measurements in the implanted side, whereas in the non-implanted side no difference was (p > 0.05) found. Four patients complained of postoperative vestibular symptoms. In three of them the symptoms lasted less than 6 months postoperatively, but the fourth patient was still dizzy 6 months after cochlear implantation. No correlation was found between the above-mentioned factors and the occurrence of postoperative vertigo. In conclusion, although changes of the peripheral vestibular function of the implanted side were recorded in our patients, permanent vertigo was rare. Predictive factors for the occurrence of postoperative vestibular symptoms could not be identified.

Cochlear dysfunction in patients with acute hypothyroidism.

The effect of acute hypothyroidism on the cochlear function was studied prospectively, in a group of 52 patients with thyroid carcinoma who underwent total thyroidectomy. All patients were examined before surgery and 6-8 weeks postoperatively. During this period there was no replacement with levothyroxine and the magnitude of thyroxin depletion was monitored by serum thyroid-stimulating hormone levels. Pure-tone audiometry, tympanometry and transiently evoked otoacoustic emissions were performed. A group of healthy volunteers of similar age and sex were used as controls. Tympanograms were normal, either on initial or on repeat testing. Audiometry showed elevation of all postoperative hearing thresholds, whereas the thresholds varied significantly across frequency. Transiently evoked otoacoustic emission testing showed response signal-to-noise ratios lower in the postoperative session (hypothyroid state) than in the preoperative session on all measured frequencies. Emission levels varied significantly across frequency, with maximum response observed at 2 kHz. Comparison of significant pure-tone and otoacoustic emission shifts for individual ears showed more ears affected in otoacoustic emission testing, indicating subclinical involvement. Comparing hearing thresholds and otoacoustic emission levels between patients and controls showed significant differences on postoperative testing. It may be thus concluded that acute hypothyroidism causes elevation of hearing thresholds in humans and to a greater degree subclinical damage of the cochlear function.

Benign paroxysmal positional vertigo associated with Meniere's disease: epidemiological, pathophysiologic, clinical, and therapeutic aspects.

OBJECTIVES: We studied the demographic, pathogenetic, and clinical features of benign paroxysmal positional vertigo (BPPV) associated with Meniere's disease. METHODS: The medical records of patients with BPPV associated with Meniere's disease were reviewed. In all patients, results of a complete otolaryngological, audiological, and neurotologic evaluation, including nystagmography, were available. Patients with idiopathic BPPV were used as a control group. RESULTS: Twenty-nine patients with both disorders were found and were compared with 233 patients with idiopathic BPPV. The patients with BPPV associated with Meniere's disease presented the following features, in which they differed from the patients with idiopathic BPPV: 1) a higher percentage of female patients; 2) a longer duration of symptoms; 3) common involvement of the horizontal semicircular canal; 4) a greater incidence of canal paresis; and 5) more therapeutic sessions needed for cure and a higher rate of recurrence. CONCLUSIONS: The BPPV associated with Meniere's disease differs from idiopathic BPPV in regard to several epidemiological and clinical features, may follow a different course, and responds less effectively to treatment.

Benign paroxysmal positional vertigo with multiple canal involvement.

PURPOSE: The aims of this study were to describe the frequency and clinical features of benign paroxysmal positional vertigo (BPPV) with multiple canal involvement and to evaluate the results of treatment by appropriate canalith repositioning procedures. MATERIALS AND METHODS: A total of 345 patients were referred for BPPV between 2006 and 2010. Thirty-two of them (9.3%) who had BPPV of multiple canals were studied. Thirteen were men (mean age, 60.4 years) and 19 were women (mean age, 56.8 years). Dix-Hallpike and supine roll tests were performed for diagnosis. Canalith repositioning procedures for treatment included modified Epley, barbecue, Gufoni, and anterior BPPV-specific maneuvers. RESULTS: Twenty-one patients had bilateral posterior canal BPPV, and 11 had mixed canal BPPV either on the same side (7 patients) or on both sides (4 patients). Thirty-one patients were cured with an average of 2.9 therapeutic sessions per patient. Recurrences occurred in 5 patients (15.6%). CONCLUSIONS: Benign paroxysmal positional vertigo of multiple canals is not rare and presents a clinical challenge. However, accurate diagnosis results in successful treatment comparable with BPPV of 1 canal.

Bilateral sudden sensorineural hearing loss caused by alcohol abuse and heroin sniffing.

Objective. Acute or chronic heroin abuse has been associated with various central neurologic pathologies and, occasionally, with peripheral nervous system damage. The effect of heroin on hearing has not been adequately documented, although several cases with sudden hearing loss owed to heroin abuse have been reported. We present a young male with bilateral sudden sensorineural hearing loss, following heroin sniffing and alcohol consumption. Methods. Our patient underwent a detailed clinical and audiological evaluation, including auditory brainstem responses and otoacoustic emission. Routine laboratory blood tests and imaging studies were performed. Results. The patient was treated with corticosteroids and magnesium, resulting in complete restoration of hearing after one month. Conclusion. Sudden hearing loss owed to heroin abuse is usually curable, following adequate treatment.

Subjective benign paroxysmal positional vertigo.

OBJECTIVE: To study the demographic, clinical, pathogenetic, and nystagmographic features and treatment outcomes of subjective benign paroxysmal positional vertigo (BPPV). STUDY DESIGN: Prospective clinical trial. SETTING: Tertiary referral center. SUBJECTS AND METHODS: Sixty-three patients were studied (mean [SD] age 55.4 [9.4] years), 27 men and 36 women, who presented with a positive history for BPPV and Dix-Hallpike or supine roll tests positive for vertigo but negative for nystagmus. A comprehensive history was obtained, followed by clinical examination of the ears, nose, and throat and a complete audiologic and neurotologic examination, including videonystagmography. All patients were treated with the appropriate canalith repositioning procedure, depending on the type of provoking positioning test. A group of 204 patients with typical BPPV were used for comparison. RESULTS: Forty-five patients with subjective BPPV were successfully treated. Eighteen patients, in most of whom vertigo of other causes was identified, did not respond to treatment. Comparison between patients with subjective and typical BPPV showed similar epidemiological and clinical features. Treatment failed in 13.5% of patients with subjective disease, after excluding patients with different causes of positional vertigo, as compared with 7.8% of patients with typical BPPV (odds ratio = 1.8; 95% confidence interval, 0.7-4.7; P = .32). CONCLUSION: Subjective BPPV is quite common, accounting for more than one-fourth of patients with typical BPPV and sharing common features with it, with the exception of nystagmus. No statistical difference in treatment outcomes between patients with subjective and typical BPPV was found, but study of a larger sample is needed.

Study of allergic rhinitis in childhood.

Allergic rhinitis is common among children and quite often represents a stage of the atopic march. Although sensitization to food and airborne allergens may appear in infancy and early childhood, symptoms of the disease are usually present after age 3. The aim of this study was to determine the most frequent food and indoor and outdoor respiratory allergens involved in allergic rhinitis in children in the region of Piraeus. The study was performed in the outpatient clinic of otolaryngologic allergy of a general hospital. Fifty children (ranged 6-14 ) with symptoms of allergic rhinitis and positive radioallergosorbent test (RAST) for IgE antibodies or skin prick tests were included in the study. Thirty six (72%) of the subjects of the study had intermittent allergic rhinitis. The most common aeroallergens determined were grass pollens and Parietaria, whereas egg and milk were the food allergens identified. The detection of indoor and outdoor allergens in the region of Piraeus, based on skin prick tests and RAST tests, showed high incidence of grasses and food allergens, which is similar to other Mediterranean countries.
