Use of Ultrasound to Verify the Impact of Telemedicine Myofunctional Therapy on Sleep Apnea Syndrome: Study Protocol Proposal.

The anatomy of the upper airways influences the risk of obstructive sleep apnea (OSA). The size of soft tissue structures, such as the tongue, soft palate, and lateral walls of the pharynx, contributes to the pathogenesis of OSA. New lines of treatment for sleep apnea, such as myofunctional therapy (MT), aim to strengthen the oropharyngeal musculature to improve the defining parameters of apnea. The present protocol uses ultrasound imaging to measure the size of the lingual musculature non-invasively and cost-effectively and evaluates the changes in its morphology. Eligible patients include those with OSA who have undergone submental cervical ultrasound and drug-induced sleep endoscopy before starting MT with the AirwayGym app. Follow-up evaluations are conducted at 3 months after beginning treatment. Patients diagnosed with OSA via questionnaires and polysomnography or respiratory polygraphy are evaluated anatomically and functionally using the Iowa Oral Performance Instrument, a tongue digital spoon, somnoscopy, and submental cervical ultrasound to assess their responses to the AirwayGym app. The lingual thickness (mm) and volume (cm3) and the distance between both lingual arteries (mm) are measured. The AirwayGym app helps users and therapists monitor the patient performance of MT. Incorporating submental ultrasound can be a useful non-invasive tool to evaluate OSA and MT.

Improving Adherence to Myofunctional Therapy in the Treatment of Sleep-Disordered Breathing.

Myofunctional therapy (MT) is used to treat sleep-disordered breathing. However, MT has low adherence-only ~10% in most studies. We describe our experiences with MT delivered through a mobile health app named Airway Gym®, which is used by patients who have rejected continuous positive airway pressure and other therapies. We compared ear, nose, and throat examination findings, Friedman stage, tongue-tie presence, tongue strength measured using the Iowa oral performance instrument (IOPI), and full polysomnography before and after the 3 months of therapy. Participants were taught how to perform the exercises using the app at the start. Telemedicine allowed physicians to record adherence to and accuracy of the exercise performance. Fifty-four patients were enrolled; 35 (64.8%) were adherent and performed exercises for 15 min/day on five days/week. We found significant changes (p < 0.05) in the apnoea-hypopnoea index (AHI; 32.97 ± 1.8 to 21.9 ± 14.5 events/h); IOPI score (44.4 ± 11.08 to 49.66 ± 10.2); and minimum O2 saturation (80.91% ± 6.1% to 85.09% ± 5.3%). IOPI scores correlated significantly with AHI after the therapy (Pearson r = 0.4; p = 0.01). The 19 patients who did not adhere to the protocol showed no changes. MT based on telemedicine had good adherence, and its effect on AHI correlated with IOPI and improvement in tongue-tie.

Myofunctional Therapy App for Severe Apnea-Hypopnea Sleep Obstructive Syndrome: Pilot Randomized Controlled Trial.

BACKGROUND: Myofunctional therapy has demonstrated efficacy in treating sleep-disordered breathing. We assessed the clinical use of a new mobile health (mHealth) app that uses a smartphone to teach patients with severe obstructive sleep apnea-hypopnea syndrome (OSAHS) to perform oropharyngeal exercises. OBJECTIVE: We conducted a pilot randomized trial to evaluate the effects of the app in patients with severe OSAHS. METHODS: Forty patients with severe OSAHS (apnea-hypoxia index [AHI]>30) were enrolled prospectively and randomized into an intervention group that used the app for 90 sessions or a control group. Anthropometric measures, Epworth Sleepiness Scale (0-24), Pittsburgh Sleep Quality Index (0-21), Iowa Oral Performance Instrument (IOPI) scores, and oxygen desaturation index were measured before and after the intervention. RESULTS: After the intervention, 28 patients remained. No significant changes were observed in the control group; however, the intervention group showed significant improvements in most metrics. AHI decreased by 53.4% from 44.7 (range 33.8-55.6) to 20.88 (14.02-27.7) events/hour (P<.001). The oxygen desaturation index decreased by 46.5% from 36.31 (27.19-43.43) to 19.4 (12.9-25.98) events/hour (P=.003). The IOPI maximum tongue score increased from 39.83 (35.32-45.2) to 59.06 (54.74-64.00) kPa (P<.001), and the IOPI maximum lip score increased from 27.89 (24.16-32.47) to 44.11 (39.5-48.8) kPa (P<.001). The AHI correlated significantly with IOPI tongue and lip improvements (Pearson correlation coefficient -0.56 and -0.46, respectively; both P<.001). The Epworth Sleepiness Scale score decreased from 10.33 (8.71-12.24) to 5.37 (3.45-7.28) in the app group (P<.001), but the Pittsburgh Sleep Quality Index did not change significantly. CONCLUSIONS: Orofacial exercises performed using an mHealth app reduced OSAHS severity and symptoms, and represent a promising treatment for OSAHS.

Tongue peak pressure: a tool to aid in the identification of obstruction sites in patients with obstructive sleep apnea/hypopnea syndrome.

Purpose of this study was to evaluate whether tongue peak pressure measured using the Iowa Oral Performance Instrument is correlated with the topographic site of obstruction in patients with obstructive sleep apnea/hypopnea syndrome observed during drug-induced sleep endoscopy. Thirty-five consecutive adult patients (29 men, 6 women) were prospectively enrolled after having been diagnosed with severe obstructive sleep apnea/hypopnea syndrome by polysomnography. An apnea-hypopnea index > 30 was confirmed, and age, gender, and body mass index were recorded by Epworth Sleepiness Scale questionnaire, and a thorough evaluation of the upper airway by video-flexible endoscopy. Twenty healthy controls according to age and sex were chosen for IOPI measurements. After drug-induced sleep endoscopy, a topographic diagnosis was done using the VOTE classification. Tongue and lip peak pressures were both measured using the Iowa Oral Performance Instrument in all patients and in 20 healthy controls. Main outcomes and measures: the correlations between office findings, Iowa Oral Performance Instrument measures, and the VOTE tongue classification during drug-induced sleep endoscopy (T0, T1, T2) were then investigated. RESULTS: The average Iowa Oral Performance Instrument tongue and lip pressure were 44.02 ± 12.29 and 15.03 ± 3.71 kPa, respectively. The Iowa Oral Performance Instrument scores were both significantly lower than values in healthy controls (P < 0.001). The VOTE classification referring to the tongue position was T0 in 13 cases (37.1%), T1 in 12 cases (34.3%), and T2 in 10 cases (28.6%). A significant correlation was found between the Iowa Oral Performance Instrument tongue pressure and the T size during drug-induced sleep endoscopy (Kruskal-Wallis χ2 25.82; P ≤ 0.001). CONCLUSIONS: In our experience, the Iowa Oral Performance Instrument is a useful tool for evaluating tongue collapse for the topographic diagnosis of patients with obstructive sleep apnea/hypopnea syndrome.

[Influence of asthma inhalers on a breath alcohol test]. / Influencia del uso de inhaladores en la estimación del grado de alcoholemia mediante determinación de etanol en aire espirado.

BACKGROUND: People and authorities are worried about interferences in breath alcohol measurements. The influence of different inhalers on breath alcohol tests is analysed in this paper. PATIENTS AND METHOD: We included 60 patients treated with different inhalers. They underwent a breath alcohol test before treatment and 1, 2, 3, 5 and 10 min after it. RESULTS: Every medication led to positive readings within the first minutes of its administration. However, all values reached zero at 10 min. Patients administered higher doses and those who did not use a spacer device were found to have higher reading values. CONCLUSIONS: Asthma inhalers, including those without alcohol contents, lead to positive readings of breath alcohol measuring devices within the first minutes. However, these interferences are no longer detected at 10 min.
