ABSTRACT

Background: During articulation the velopharynx needs to be opened and closed rapidly and a tight closure is needed. Based on the hypothesis that patients with cleft lip and palate (CLP) produce lower pressures in the velopharynx than healthy individuals, this study compared pressure profiles of the velopharyngeal closure during articulation of different sounds between healthy participants and patients with surgically closed unilateral CLP (UCLP) using high resolution manometry (HRM). Materials and methods: Ten healthy adult volunteers (group 1: 20-25.5 years) and ten patients with a non-syndromic surgically reconstructed UCLP (group 2: 19.1-26.9 years) were included in this study. Pressure profiles during the articulation of four sounds (/i:/, /s/, /ʃ/ and /n/) were measured by HRM. Maximum, minimum and average pressures, time intervals as well as detection of a previously described 3-phase-model were compared. Results: Both groups presented with similar pressure curves for each phoneme with regards to the phases described and pressure peaks, but differed in total pressures. An exception was noted for the sound /i:/, where a 3-phase-model could not be seen for most patients with UCLP. Differences in velopharynx pressures of 50% and more were found between the two groups. Maximum and average pressures in the production of the alveolar fricative reached statistical significance. Conclusions: It can be concluded that velopharyngeal pressures of patients with UCLP are not sufficient to eliminate nasal resonance or turbulence during articulation, especially for more complex sounds. These results support a general understanding of hypernasality during speech implying a (relative) velopharyngeal insufficiency.

ABSTRACT

Introduction: Rhinophonia aperta may result from velopharyngeal insufficiency. Neuromuscular electrical stimulation (NMES) has been discussed in the context of muscle strengthening. The aim of this study was to evaluate in healthy subjects whether NMES can change the velopharyngeal closure pattern during phonation and increase muscle strength. Method: Eleven healthy adult volunteers (21-57 years) were included. Pressure profiles were measured by high resolution manometry (HRM): isolated sustained articulation of /a/ over 5 s (protocol 1), isolated NMES applied to soft palate above motor threshold (protocol 2) and combined articulation with NMES (protocol 3). Mean activation pressures (MeanAct), maximum pressures (Max), Area under curve (AUC) and type of velum reactions were compared. A statistical comparison of mean values of protocol 1 versus protocol 3 was carried out using the Wilcoxon signed rank test. Ordinally scaled parameters were analyzed by cross table. Results: MeanAct values measured: 17.15±20.69 mmHg (protocol 1), 34.59±25.75 mmHg (protocol 3) on average, Max: 37.86±49.17 mmHg (protocol 1), 87.24±59.53 mmHg (protocol 3) and AUC: 17.06±20.70 mmHg.s (protocol 1), 33.76±23.81 mmHg.s (protocol 3). Protocol 2 produced velum reactions on 32 occasions. These presented with MeanAct values of 13.58±12.40 mmHg, Max values of 56.14±53.14 mmHg and AUC values of 13.84±12.78 mmHg.s on average. Statistical analysis comparing protocol 1 and 3 showed more positive ranks for MeanAct, Max and AUC. This difference reached statistical significance (p=0.026) for maximum pressure values. Conclusions: NMES in combination with articulation results in a change of the velopharyngeal closure pattern with a pressure increase of around 200% in healthy individuals. This might be of therapeutic benefit for patients with velopharyngeal insufficiency.

ABSTRACT

BACKGROUND: The process of aging involves numerous changes in the body, influencing physical, mental, and emotional well-being. Age-related changes and degradation can impact various functions of the swallowing process and lead to delayed word retrieval. Individuals with limited linguistic stimulation may experience a more rapid decline in cognitive performance. Thus, this project explores a preventive training program targeting swallowing and linguistic-communicative skills, aimed at preserving the social participation of older individuals residing in nursing homes. METHODS: A preventive intervention program, combining orofaciopharyngeal and linguistic-communicative components, will be offered twice weekly over 12 weeks in long-term care facilities in the greater Hanover area. The program will aim at: (a) activating sensitive and motor skills in the orofaciopharyngeal area to counter age-related swallowing disorders, and (b) enhancing communicative abilities through semantic-lexical activation. A cluster randomized controlled trial will be conducted to investigate whether the intervention program improves swallowing skills in older adults. Additionally, a secondary analysis will explore the impact on language skills and social participation, as well as program acceptance. DISCUSSION: The results will provide valuable insight into the effectiveness of preventive measures addressing swallowing and speech issues in older individuals. TRIAL REGISTRATION: The trial was registered with DRKS (German register for clinical trials) in June 2023 (study ID: DRKS00031594) and the WHO International Clinical Trail Registry Platform (secondary register).

ABSTRACT

BACKGROUND: The flexible endoscopic evaluation of swallowing (FEES) is an established low-risk examination method to assess the risk of penetration or aspiration in patients with dysphagia. FEES might be more difficult or of higher-risk when a nasogastric tube is in place. OBJECTIVE: This study aims to identify whether the prevalence of mucosal lesions is higher when the endoscopy is carried out with a nasogastric tube in place. Pre-existing mucosal lesions were also documented. METHODS: In a retrospective, monocentric study, a total of 918 FEES procedures routinely performed in hospitalized patients of a university hospital from January 2014 to March 2019 were evaluated. Mucosal lesions were identified and characterized for descriptive statistics. RESULTS: In the video material analysed here, no endoscopy-related injuries were identified. However, pre-existing mucosal lesions, which often occurred as multiple lesions, were detected in 48.6% of the endoscopies. Further analysis showed that these pre-existing lesions were not worsened by the endoscopy performed. CONCLUSION: The results demonstrate that transnasal flexible endoscopy is a safe, low-risk examination method, even in patients with a nasogastric tube. A very high number of pre-existing mucosal lesions were found, which is probably related to the previous insertion of the nasogastric tube. Due to the high number of pre-existing lesions, strategies should be developed to minimize injuries when placing nasogastric tubes.

ABSTRACT

The recognition of Auditory Processing Disorder (APD) as a distinct clinical condition that impacts hearing capacity and mental health has gained attention. Although pure tone audiometry is the gold standard for assessing hearing, it inadequately reflects everyday hearing abilities, especially in challenging acoustic environments. Deficits in speech perception in noise, a key aspect of APD, have been linked to an increased risk of dementia. The World Health Organization emphasizes the need for evaluating central auditory function in cases of mild hearing loss and normal audiometry results. Specific questionnaires play a crucial role in documenting and quantifying the difficulties faced by individuals with APD. Validated questionnaires such as the Children's Auditory Processing Performance Scale, the Fisher's Auditory Problems Checklist, and the Auditory Processing Domains Questionnaire are available for children, while questionnaires for adults include items related to auditory functions associated with APD. This systematic review and meta-analysis identified six questionnaires used for screening and evaluating APD with a total of 783 participants across 12 studies. The questionnaires exhibited differences in domains evaluated, scoring methods, and evaluation of listening in quiet and noise. Meta-analysis results demonstrated that individuals with APD consistently exhibited worse scores compared to healthy controls across all questionnaires. Additionally, comparisons with clinical control groups showed varying results. The study highlights (i) the importance of standardized questionnaires in identifying and assessing APD, aiding in its diagnosis and management, and (ii) the need to use sub-scores as well as overall scores of questionnaires to elaborate on specific hearing and listening situations. There is a need to develop more APD specific questionnaires for the adult population as well as for more focused research on APD diagnosed individuals to further establish the validity and reliability of these questionnaires.

ABSTRACT

INTRODUCTION: The upper esophageal sphincter (UES) has been reported to show activity during phonation. As it is still unknown whether the phonation-induced UES contraction represents a reflex or a simultaneous activation phenomenon, i.e. co-innervation, this study aims to investigate and characterize the phonation-induced contraction of the UES in healthy individuals by analyzing the influence of various phonation tasks on pressure parameters of the UES. METHODS: Twenty-five healthy volunteers produced the German neutral vowel [ə] in five different phonation tasks (modal voice, whispering, voiceless speech, creaky voice, and whispery voice). Simultaneously, they underwent high resolution manometry and electroglottography for measurement of pressure parameters in the region of the UES and latencies between larynx and UES activation. RESULTS: During all types of phonation, the maximum pressures of the UES increased significantly (maximum pressure increases of 72%-132%). With regard to mean pressures this was valid for modal voice and whispering (mean pressure increases of 20%-25%). Differences concerning total pressure changes reached statistical significance when comparing whispering and voiceless speech as well as whispery voice. However, differences concerning the total pressure change between modal voices on the one hand and voiceless speech and whispery voice on the other hand turned out to be small. The averaged time delay between larynx and UES activation ranged from approximately -15 ms (whispery voice) to +15 ms (whispering). CONCLUSION: A phonation induced pressure increase of the UES was confirmed in this study and did exist for different types of phonation. The extent of total pressure changes in the UES increases in relation with laryngeal muscle activity necessary for the phonation type. Next to varying effects of different types of phonation on UES activation, very short latencies indicate that a phonation induced contraction of the UES exists most likely due to co-innervation of UES and laryngeal muscles by the vagus nerve.

ABSTRACT

Background: Neuromuscular electrical stimulation (NMES) has been used as a treatment option in the therapy of dysphagia for several years. In a previous review of the literature, it was concluded that NMES might be a valuable adjunct in patients with dysphagia and in patients with vocal fold paresis. However, due to different stimulation protocols, electrode positioning and various underlying pathological conditions, it was difficult to compare the studies which were identified and it was concluded that more empirical data is needed to fully understand the benefits provided by NMES. The purpose of this systematic review is, therefore, to evaluate recent studies regarding a potential effectiveness of transcutaneous NMES applied to the anterior neck as a treatment for dysphagia considering these different aspects. Method: For this systematic review, a selective literature research in PubMed has been carried out on 5th May 2021 using the terms electrical stimulation AND dysphagia and screened for inclusion criteria by two reviewers in Rayyan. The search resulted in 62 hits. Results: Studies were excluded due to their publication language; because they did not meet inclusion criteria; because the topical focus was a different one; or because they did not qualify as level 2 studies. Eighteen studies were identified with varying patient groups, stimulation protocols, electrode placement and therapy settings. However, 16 studies have reported of beneficial outcomes in relation with NMES. Discussion: The purpose of this systematic review was to evaluate the most recent studies regarding a potential effectiveness of NMES as a treatment for oropharyngeal dysphagia considering different aspects. It could generally be concluded that there is a considerable amount of level 2 studies which suggest that NMES is an effective treatment option, especially when combined with TDT for patients with dysphagia after stroke and patients with Parkinson's disease, or with different kinds of brain injuries. Further research is still necessary in order to clarify which stimulation protocols, parameters and therapy settings are most beneficial for certain patient groups and degrees of impairment.

ABSTRACT

OBJECTIVES/HYPOTHESIS: The laryngeal adductor reflex (LAR) is an important protective mechanism of the airways. Its physiology is still not completely understood. The available methods for LAR evaluation offer limited reproducibility and/or rely on subjective interpretation. A new approach, termed Microdroplet Impulse Testing of the LAR (MIT-LAR), was recently introduced. Here, the LAR is elicited by a droplet and a laryngoscopic high-speed recording is acquired simultaneously. In the present work, image-processing algorithms for autonomous MIT-LAR sequence analysis were developed. This allowed the automated approximation of kinematic LAR parameters in humans. STUDY DESIGN: Development and testing of computational methods. METHODS: Computational image processing enabled the autonomous estimation of the glottal area, the glottal angle, and the vocal fold edge distance in MIT-LAR sequences. A suitable analytical representation of these glottal parameters allowed the extraction of seven relevant LAR parameters. The obtained values were compared to the literature. RESULTS: A generalized logistic function showed the highest average goodness of fit among four different analytical approaches for each of the glottal parameters. Autonomous sequence analysis yielded bilateral LAR response latencies of (229 ± 116) ms and (182 ± 60) ms for cases of complete and incomplete glottal closure, respectively. The initial/average/maximum angular vocal fold adduction velocity was estimated at (157 ± 115) °s-1 /(891 ± 516) °s-1 /(929 ± 583) °s-1 and (88 ± 53) °s-1 /(421 ± 221) °s-1 /(520 ± 238) °s-1 for complete and incomplete glottal closure, respectively. CONCLUSION: The automated extraction of LAR parameters from laryngoscopic high-speed sequences can potentially increase the objectiveness of optical LAR characterization and reduce the associated workload. The proposed methods may thus be helpful for future research on this vital reflex. LEVEL OF EVIDENCE: NA Laryngoscope, 132:2412-2419, 2022.

ABSTRACT

Background: Previous results of clinical studies suggest that neuromuscular electrostimulation (NMES) therapy, especially in combination with traditional dysphagia therapy, may be helpful in patients with neurogenic swallowing disorders. In these studies, repetitive application of a rectangular current impulse was used to increase muscle strength of the anterior neck. However, according to sports physiological findings, an increase of muscle strength can be better achieved by using different NMES stimulation protocols, e.g. KOTS. The aim of the translational investigator-initiated, non-commercial pilot study presented here was to provide data and insights for the planning of subsequent phase II and III studies on the effectiveness of such stimulation protocols in dysphagia therapy. Methods: 30 post-stroke patients with oropharyngeal dysphagia were included in this prospective pilot study and randomly allocated to either neuromuscular electrostimulation (NMES) or sham stimulation in combination with traditional dysphagia therapy (TDT), a pre- and post-therapeutic fiberoptic-endoscopic evaluation of swallowing (FEES) with the Dysphagia Outcome and Severity Scale (DOSS) (primary outcome measure), Secretion Scale by Murray, Penetration and Aspiration Scale (PAS) and throat clearance (TC) abilities. Recruitment rate, interrater comparison and number of relevant adverse events were recorded as metadata. Results: Despite a recruiting time of over 24 months, only twelve patients could be included. Moreover, clinical data indicated a significant variance of clinical pictures. Significant differences in verum versus sham therapy were not observed. DOSS values in both study groups showed general improvements at the end of the trial. Interrater reliability was low. No adverse events were reported. Discussion: When planning further dysphagia therapy studies, it must be taken into account that it can be problematic to recruit sufficiently large study collectives within an appropriate study period. This is especially important since a possible additional benefit of NMES to TDT is probably rather small or may only occur in certain deficit constellations. The low interrater reliability observed here must be improved by appropriate training measures. Fortunately, no relevant undesirable side effects occurred. This could have a positive effect on the acceptance of volunteers to participate in the study.

ABSTRACT

Introduction: Speech dysfluency, often referred to as stuttering, is a frequent speech disorder encountered in about 5% of children. Although in the majority of people affected, symptoms improve in adulthood, in some patients, stuttering persists and significantly impairs everyday functioning and quality of life. Treatment for stuttering includes speech therapy, cognitive behavioral therapy, and relaxation techniques. However, a substantial number of patients do not benefit sufficiently from these treatment strategies or are even treatment resistant. Methods: We present the case of a 20-year-old male with treatment-resistant stuttering, who markedly improved after treatment with medicinal cannabis. Results: Besides improved speech fluency as assessed by several phoniatric tests, we observed remission of (social) anxiety, improved mood, and reduced stress, resulting in an overall improvement of quality of life after cannabis therapy. The patient, in addition, reported improved attention, concentration, and sleep, increased self-confidence, and better social life. No side effects occurred. Over a time period of more than a year, treatment was equally effective. In an interview, the patient describes his personal view and the influence of cannabis-based treatment on his life. Conclusions: Medicinal cannabis could be effective in treatment of refractory stuttering, but these preliminary data have to be confirmed in controlled studies.

ABSTRACT

Mechanisms of the upper esophageal sphincter (UES) when exposed to acid are still incompletely understood. The presented work investigated the reaction of the UES to acid exposure during swallowing. Ten healthy individuals swallowed ten 2 ml neutral water boli of pH 7, followed by 10 swallows each of different levels of acidity (pH 1.8, pH 3 and pH 5). Effects were analyzed by high-resolution manometry (HRM) for the primary parameter Restitution Time, as well as Resting Pressures, maximal, minimal pressures and time intervals. Restitution Times measured mean values of 12.67 s (SD ± 7.03 s) for pH 1.8, pH 7 = 8.69 s (SD ± 2.72 s), pH 3 = 7.56 s (SD ± 2.23 s) and pH 5 = 7.29 s (SD ± 2.55 s), showing prolonged Restitution Times in the UES when exposed to strong bolus acidity. This difference was significant towards the neutral bolus, but also to less acidic boli (pH 5: p = 0.006, pH 3: p = 0.009, pH 7: p = 0.038). Considerable differences of mean values were found for Post-Swallow Maximum and Period of Sphincter Activity. Also, Pre-Swallow Maximum values were found to be highest with the strongest acid. Relaxation Times showed a slight trend of prolongation for the highest bolus acidity. Prolonged Restitution Times may represent a reflexive protective mechanism triggered by receptors in the pharyngeal mucosa or the UES preventing regurgitation of acid into the pharynx and larynx, besides representing ongoing attempts of acid clearance. Exposure to high levels of acidity by a swallowed bolus does influence UES functions during swallowing.

ABSTRACT

OBJECTIVE: The laryngeal adductor reflex (LAR) is an important mechanism to secure the airways from potential foreign body aspiration. An involvement of the upper esophageal sphincter (UES) in terms of a laryngo-UES contractile reflex has been identified after laryngeal mucosa stimulation. However, the LAR-UES relationship has not yet been fully explained. This study aimed to determine the magnitude, latency, and occurrence rate of the UES pressure response when the LAR is triggered in order to elucidate the functional relationship between the larynx and the UES. METHODS: This prospective study included seven healthy volunteers (5 female, 2 male, age 22-34 years). Laryngeal penetration was simulated by eliciting the LAR 20 times in each individual by applying water-based microdroplets onto the laryngeal mucosa. UES pressures were measured simultaneously using high-resolution manometry. RESULTS: Two distinct pressure phases (P1, P2) associated with the LAR were identified. P1 corresponded with a short-term UES pressure decrease in two subjects and a pressure increase in five subjects occurring 200 to 500 ms after the stimulus. In P2, all subjects experienced an increase in UES pressure with a latency time of approximately 800 to 1700 ms and an average of 40 to 90 mmHg above the UES resting tone. CONCLUSION: Foreign bodies penetrating the laryngeal inlet lead to a reflex contraction of the UES. Phase P1 could be a result of vocal fold activity caused by the LAR, leading to pressure changes in the UES. The constriction during P2 could strengthen the barrier function of the UES in preparation to a subsequent cough that may be triggered to clear the airways.

ABSTRACT

PURPOSE: This study aims to attain metric data of the velopharyngeal dimensions of healthy subjects as well as patients with velopharyngeal insufficiency using the example of cleft and lip palate (CLP) in order to determine possible differences in the volumes of both groups. METHODS: Volumes and distances of velopharyngeal areas were analyzed retrospectively using cone beam computed tomography data sets (n = 60). Group 1 included healthy patients receiving dental implants (n = 31). Group 2 was represented by patients with surgically closed cleft lip and palate (n = 29). RESULTS: Biggest differences among mean values of both groups were found for: minimum axial area (p = 0.000), airway area caudal (p = 0.000), distance between posterior nasal spine and posterior pharyngeal wall (PPW) (p = 0.014), mean distance between velum and PPW (p = 0.000), length of PPW (p = 0.000) and length of anterior pharyngeal wall (p = 0.000). CONCLUSION: Differences in the shape and geometry of the velopharyngeal area in subjects with a regular velopharyngeal structure and function and patients with cleft palate do exist. The significant differences found here can be categorized into two groups: one reflects distances between the anterior and posterior pharynx, presenting longer distances for patients with CLP. The second significant difference regards values of length in cranio-caudal direction, which is longer in healthy subjects. With regards to these values, one could conclude, that even though total volumes of both groups did not differ in size, group 1 shows three-dimensional velopharyngeal shapes that are longer and narrower, whereas shapes of patients of group 2 tend to be wider and shorter in general.

ABSTRACT

OBJECTIVE: To evaluate pharyngeal pressure profiles during swallowing in patients with unilateral cleft lip and palate (UCLP) and identify compensation mechanisms. DESIGN: Prospective experimental study. SETTING: University Hospital and Medical School. PARTICIPANTS: Ten volunteers and 10 patients with nonsyndromic repaired UCLP with hypernasality (age: 19-27 years, 5 females and 5 males per group) were included. INTERVENTIONS: All participants swallowed 2 and 10 mL of water and underwent high-resolution manometry (HRM). MAIN OUTCOME MEASURES: Pharyngeal and upper esophageal sphincter (UES) parameters were measured using HRM. Student t test was used for statistical intergroup comparisons. Additionally, the Sydney Swallowing Questionnaire (SSQ) was used as a subjective measure. RESULTS: Patients exhibited reduced velopharyngeal closing pressure and velopharyngeal and tongue base (TB) region contraction times, compared to volunteers (P < .05). The UES opening and closing functions did not change. The SSQ revealed nasal regurgitation in some patients. CONCLUSIONS: In patients with UCLP, velopharyngeal region alterations are caused by impaired muscle force and function. The reduced TB contraction time may be a compensation mechanism allowing bolus transportation without nasal regurgitation. However, deglutition is not completely altered since UES function remains normal. Future studies will need to reveal at which point a decrease in velopharyngeal closing pressure will result in velopharyngeal insufficiency.

ABSTRACT

PURPOSE: This study aims to determine Euclidean distances between landmark structures in the larynx and pharynx to optimize endoscope shaft designs with regard to gentle and patient-oriented handling. METHODS: Four Euclidean distances between landmarks in the larynx and pharynx were analyzed based on CT data of 66 patients. Distance (1): labium inferius oris-posterior pharyngeal wall at the cervical vertebra C1 (atlas), anterior edge of the tuberculum anterius atlantis. Distance (2): posterior pharyngeal wall adjacent to C1-entrance of pyriform sinus. Distance (3): inferior edge of the uvula-superior edge of the epiglottis. Distance (4): base of the vallecula-posterior pharyngeal wall. The minimum angular field of view α required to observe the glottis with a rigid transoral laryngoscope was derived trigonometrically from distances (2) and (4). RESULTS: Average Euclidean distances measured: Distance (1): 90.7 mm ± 6.9 mm in men and 86.9 mm ± 5.9 mm in women. (2): 73.7 mm ± 13.4 mm and 56.2 mm ± 7.6 mm. (3): 25.2 mm ± 8.6 mm and 18.5 mm ± 6.8 mm. (4): 20.8 mm ± 4.6 mm and 16.5 mm ± 3.4 mm. α: 16.0° ± 3.9° and 16.6 ± 4.3°. CONCLUSIONS: As expected, statistically significant sex-related differences could be observed for distances (1)-(4). The results indicate that the length of transoral laryngoscopes should not be below 110 mm and that a minimum angular field of view of α = 17° is required to fully observe the laryngeal inlet.

ABSTRACT

The opinion article "An Evidence-based Perspective on Misconceptions Regarding Pediatric Auditory Processing Disorder" by Neijenhuis et al. (1) presents a distorted view of the evidence-based approach used in medicine. The authors focus on the amorphous non-diagnostic entity "listening difficulties" not auditory processing disorder (APD) and create confusion that could jeopardize clinical services to individuals with APD. In our perspective article, we rebut Neijenhuis et al. (1), and more importantly, we present a rationale for evidence-based practice founded on the premise that research on APD is only clinically applicable when conducted on clinical populations diagnosed with APD.

ABSTRACT

BACKGROUND: Impairments of sound discrimination, speech comprehension in background noise, memory, etc. can be assessed within the diagnosis of an auditory processing and perception disorder (AVWS) in a structured manner using the questionnaire (DGPP-AVWS-FB) provided by the German Society for Phoniatrics and Pedaudiology. The aim is to report on experiences with the use of this questionnaire in a pedaudiology practice. In particular, it was to be determined whether information on the auditory behaviour provided by parents is similar or different to information provided by kindergarten teachers (KGK) or teachers at school (LK). METHODS: During a nine-month period, all parents who presented their children to be examined for a possible AVWS were handed the DGPP-AVWS-FB to be completed by them and by KGK/LK. In order to compare the agreement of the judgements, two questionnaires on attention and concentration or on executive functions (DISYPS II, BRIEF or BRIEF-P) were also given. Data from children with peripheral hearing impairment or cognitive developmental disorder were not used. The correlation coefficient was then calculated for the respective items, scales and indices. RESULTS: Completed questionnaires were available at the end of the study period for a total of 20 primary school children and 7 kindergarten children. In kindergarten children, only KGK but not parents, in school children however, 1x only parents, 16x only LK and in the remaining 3 others both parents and LK suspected an impaired auditory processing. The evaluation of the DGPP-AVWS-FB ultimately reflected this different assessment of the symptoms: with the exception of children in whom both parents and LK suspected an AVWS, the information provided by the parents showed only little agreement with the information provided by the KGK/LK. In comparison, the responses to the other two questionnaires were also different, but the data on attention and hyperactivity in kindergarten children tended to be more similar. DISCUSSION: The data presented could be explained by a different behavior of the children at home or in kindergarten/school. It could also be that the same behavior is evaluated differently. Low correlations are already known for questionnaires on attention deficit/hyperactivity disorder and executive functions.For the clinical routine it is recommended to document the reported symptoms standardized with the DGPP-AVWS-FB and in particular to determine whether an abnormal auditory behavior is noticeable in only one or two or more environments.

ABSTRACT

BACKGROUND: Chronic rhinosinusitis (CRS) is one of the most common chronic diseases in Germany and is often accompanied by years of chronic rhinosinusitis. According to the current German guideline "Rhinosinusitis", the nasal application of salt solutions, topical corticosteroids and in individual cases also systemic corticosteroids appear useful for a symptomatic therapy of CRS. The evidence for other therapeutic procedures such as acupuncture, homeopathy and phytotherapeutics is seen as insufficient. The aim of the present study was to investigate whether anti-inflammatory effects of electrostimulation therapy can also be demonstrated in CRS. METHODOLOGY: randomized, prospective single center study, primary setting; 16 patients with moderate chronic rhinosinusitis with polyps (cRScNP), corresponding to a Lund / Mackay score of 6-12; home based electrostimulation therapy (EST) with amplitude modulated current (base frequency of 4000 Hz, frequency band of 100-250 Hz) over 2 weeks adjuvant to a concurrent sinusitis therapy with topical corticosteroids; measurement of nasal nitric oxide concentration and self-assessment of complaints with the questionnaire instrument SNOT-20 GAV; survey points t0 before EST, t1 after EST, t2 6 weeks after t1. RESULTS: Home based EST was performed by 16 patients. The results indicate that the positive effects of electrostimulation therapy in inflammatory processes also exist in CRS. DISCUSSION: Adjuvant transsinuidal electrostimulation could thus enrich the conservative therapy of CRS. Further studies with larger collectives are desirable.
