Modified inspiratory muscle training (m-IMT) as promising treatment for gastro-oesophageal reflux disease (GERD).

BACKGROUND: Gastro-oesophageal reflux disease (GERD) is one of the most common diseases, but is still a challenge to cure. Different medical treatments are used, first of all Proton pump inhibitors (PPIs), however these are sometimes ineffective and long-term intake can lead to underestimated complications. Recently, some studies investigated the role of inspiratory muscle training (IMT) in the medical treatment of GERD. It seems that IMT is able to increase the pressure generated by the lower oesophageal sphincter (LES), reduce spontaneous releases of LES, acid exposure, use of PPIs, and improve symptoms and quality of life for GERD patients. OBJECTIVE: The aim of this study was to evaluate the effectiveness of IMT in association with myofunctional therapy exercises of swallowing set by Daniel Garliner (m-IMT) on the symptoms of patients with non-erosive gastro-oesophageal reflux disease (NERD). METHODS: Twenty-one adult patients with NERD were enrolled from May to December 2017 and performed m-IMT over a period of 4 weeks. Before and after treatment, all the patients completed the following questionnaires: GERD oesophageal symptomatology (GERDQ), extra-oesophageal GERD symptomatology (RSI), quality of life (GERD-Health Related Quality of Life Questionnaire (GERD-HRQL), and underwent laryngeal endoscopy. RESULTS: Nineteen patients completed m-IMT. GERDQ (from 8.36±3.94 to 1.7±3.41; p<.05), RSI (from to 21.68±10.26 to 6.93±8.37; p<.05) and GERDHRQL (from 25.68±16.03 to 8.4±11.06; p<.05) the questionnaire scores significantly reduced after treatment. In addition, the laryngeal endoscopy score greatly improved (from 14.24±4.15 to 7.4±1.77; p<.05). CONCLUSIONS: m-IMT is a low cost therapy without side effects. It could be useful in association with PPI or alone for selected GERD cases and for mild NERD forms, in association with diet. Further studies are required to prove the effects of m-IMT on GERD symptoms and decide the best treatment schedule.

Hypoglossal nerve stimulation long-term clinical outcomes: a systematic review and meta-analysis.

OBJECTIVE: To perform a systematic review and meta-analysis for studies evaluating hypoglossal nerve stimulation (HNS) clinical outcomes in the treatment of moderate to severe obstructive sleep apnea (OSA). METHODS: Two authors conducted a literature search to identify prospective studies in PubMed/MEDLINE, Google Scholar, and Cochrane Library databases. The last search was performed on November 17, 2018. RESULTS: A total of 350 patients (median age 54.3 (IQR 53-56.25) years, BMI 29.8 (IQR 28.8-31.6) kg/m2) from 12 studies were included. The procedure has obtained a surgical success rate of 72.4% (Inspire), 76.9% (ImThera), 55% (Apnex) at 12 months, and 75% (Inspire) at 60-month follow-up. At 12 months, the apnea-hypopnea index (AHI) mean differences was - 17.50 (Inspire; 95% CI: - 20.01 to - 14.98, P < 0.001), - 24.20 (ImThera; 95% CI: - 37.39 to 11.01, P < 0.001), and - 20.10 (Apnex; 95% CI: - 29.62 to - 10.58, P < 0.001). The AHI mean reduction after 5 years was - 18.00 (Inspire, - 22.38 to - 13.62, P < 0.001). The Epworth sleepiness scale (ESS) mean reduction was - 5.27 (Inspire), - 2.90 (ImThera), and - 4.20 (Apnex) at 12 months and - 4.40 (Inspire) at 60 months, respectively. Only 6% of patients reported serious device-related adverse events after 1- and 5-year follow-up. CONCLUSION: HNS has obtained a high surgical success rate with reasonable long-term complication rate related to the device implanted. The procedure represents an effective and safe surgical treatment for moderate-severe OSA in selected adult patients who had difficulty accepting or adhering to CPAP treatment.

Saline nasal irrigations for chronic rhinosinusitis: From everyday practice to evidence-based medicine. An update.

Saline nasal irrigations (SNIs) are often recommended as an additional non-pharmacological treatment for adults with chronic rhinosinusitis (CRS), for which it could even be considered a first-line treatment. However, there is a wide range of different SNI protocols. The aim of this article is to review the published literature regarding all of the potential therapeutic effects of SNIs in adult CRS patients who had not undergone sinus surgery and clarify the role of the various saline nasal solutions and protocols (particularly the volume, frequency and duration of treatment), and describe the nasal devices used. A search was made of the PubMed, Google Scholar and Ovid databases using the key words 'saline nasal irrigation' and 'chronic rhinosinusitis', or medical subject headings. The search identified 11 studies involving 663 patients. There was no consensus about but substantial agreement concerning the frequency and duration of treatment, the type of device, and the amount of solution to be used when managing CRS. A hypertonic solution with the addition of the natural minerals and oligo-elements found in seawater and some thermal waters may be associated with greater clinical benefit in terms of endoscopic scores and mucociliary clearance than isotonic solutions. Further studies are required to compare the different forms of SNI and define SNI protocols and nasal devices, while considering patient compliance.

Cervical spine disorders and its association with tinnitus: The "triple" hypothesis.

Subjective tinnitus and cervical spine disorders (CSD) are among the most common complaints encountered by physicians. Although the relationship between tinnitus and CSD has attracted great interest during the past several years, the pathogenesis of tinnitus induced by CSD remains unclear. Conceivably, CSD could trigger a somatosensory pathway-induced disinhibition of dorsal cochlear nucleus (DCN) activity in the auditory pathway; furthermore, CSD can cause inner ear blood impairment induced by vertebral arteries hemodynamic alterations and trigeminal irritation. In genetically -predisposed CSD patients with reduced serotoninergic tone, signals from chronically stimulated DCNs could activate specific cortical neuronal networks and plastic neural changes resulting in tinnitus. Therefore, an early specific tailored CSD treatments and/or boosting serotoninergic activity may be required to prevent the creation of 'tinnitus memory circuits' in CSD patients.
