UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: Offene Rhinophonien können aufgrund einer velopharyngealen Insuffizienz entstehen. Die neuromuskuläre Elektrostimulation (NMES) wird seit einiger Zeit als Therapieform zur Muskelkräftigung angewendet. Ziel dieser Studie war es, an gesunden Proband_innen zu untersuchen, ob NMES das velopharygeale Verschlussmuster während der Phonation verändern und die Muskelkraft erhöhen kann.
UNASSIGNED: In die Studie wurden 11 gesunde Proband_innen eingeschlossen (21–57 Jahre). Mit der Hochauflösungsmanometrie wurden Druckprofile unter verschiedenen Bedingungen aufgezeichnet: die isolierte Phonation des Lautes /a/ über 5 s (Protokoll 1), die isolierte, motorisch überschwellig applizierte NMES auf das Velum (Protokoll 2) sowie die Phonation und die NMES in Kombination (Protokoll 3). Verglichen wurden der durchschnittliche Druck während der Aktivierung (MeanAct), die durchschnittlichen Maximaldrücke (Max), die durchschnittlichen Integrale unter der Druckkurve (Area under curve (AUC)) und die Art der Velumreaktion. Der Vergleich der Durchschnittswerte von Protokoll 1 und 3 wurden mithilfe des Wilcoxon-Vorzeichen-Rang-Tests durchgeführt. Ordinär skalierte Parameter wurden über eine Kreuztabelle analysiert.
UNASSIGNED: MeanAct Mittelwerte lagen bei 17,15±20,69 mmHg (Protokoll 1), 34,59±25,75 mmHg (Protokoll 3), Max bei 37,86±49,17 mmHg (Protokoll 1), 87,24±59,53 mmHg (Protokoll 3) und AUC bei 17,06±20,70 mmHg.s (Protokoll 1), 33.76±23.81 mmHg.s (Protokoll 3). Im Protokoll 2 zeigten sich 32 Velumreaktionen mit durchschnittlichen MeanAct-Werten von 13,58±12,40 mmHg, Maximalwerten von 56,14±53,14 mmHg und Mean-AUC-Werten von 13,84±12,78 mmHg.s. Der Vergleich der Protokolle 1 und 3 ergab mehr positive Ränge für die Kombination aus Phonation und NMES und für die Parameter MeanAct, Max und AUC. Dieser Unterschied zeigte mit p=0.026 statistische Signifikanz in Bezug auf den Parameter Max.
UNASSIGNED: NMES in Kombination mit Phonation führt bei Gesunden zu einer Veränderung des velopharyngealen Verschlussmusters mit einer Druckerhöhung von etwa 200%. Dies könnte für Patient_innen mit velopharyngealer Insuffizienz von therapeutischem Nutzen sein.

UNASSIGNED: GERD is a common disorder and is characterized by the presence of typical or atypical symptoms. In GERD patients, the presence of mucosal alterations in endoscopy is detected in up to 30% of individuals. The clinical presentation of GERD patients may be complex and their management is challenging, due to the heterogeneous clinical presentation. The present review has been performed searching all relevant articles in this field, over the past years, using PubMed database.
UNASSIGNED: The diagnosis and management of GERD have been significantly improved in the last years due to the increasing availability of reflux monitoring techniques and the implementation of new procedures in the therapeutic armamentarium. Beside traditional impedance-pH variables, new metrics have been developed, increasing the diagnostic yield of reflux monitoring and better predicting the treatment response. Traditional pharmacological treatments include acid-suppressive-therapy and/or anti-acid. On the other hand, surgical treatment and, more recently, endoscopic procedures represent a promising field in the therapeutic approach.
UNASSIGNED: Diagnosis and treatment of GERD still represent a challenging area. However, we believe that an accurate upfront evaluation is, nowadays, necessary in addressing patients with GERD to a more accurate diagnosis as well as to the best treatment options.

UNASSIGNED: Achalasia is an uncommon esophageal motility disorder and is characterized by alterations of the motility of the esophageal body in conjunction with altered lower esophageal sphincter (LES) relaxation. The clinical presentation of patients with achalasia may be complex; however, the most frequent symptom is dysphagia. The management of patients with achalasia is often challenging, due to the heterogeneous clinical presentation.
UNASSIGNED: The diagnosis and management of achalasia has significantly improved in the last years due to the growing availability of high-resolution manometry (HRM) and the implementation in the therapeutic armamentarium of new therapeutic endoscopic procedures. Traditional therapeutic strategies include botulinum toxin injected to the LES and pneumatic balloon dilation. On the other hand, surgical treatments contemplate laparoscopic Heller myotomy and, less frequently, esophagectomy. Furthermore, in the last few years, per oral endoscopic myotomy (POEM) has been proposed as the main endoscopic therapeutic alternative to the laparoscopic Heller myotomy.
UNASSIGNED: Diagnosis and treatment of achalasia still represent a challenging area. However, we believe that an accurate up-front evaluation is, nowadays, necessary in addressing patients with achalasia for a more accurate diagnosis as well as for the best treatment options.

Achalasia is a rare neurodegenerative disorder causing dysphagia and is characterized by abnormal esophageal motor function as well as the loss of lower esophageal sphincter (LES) relaxation. The assessment and management of achalasia has significantly progressed in recent years due to the advances in high-resolution manometry (HRM) technology along with the improvements and innovations of therapeutic endoscopy procedures. The recent evolution of HRM technology with the inclusion of an adjunctive test, fluoroscopy, and EndoFLIP has enabled more precise diagnoses of achalasia to be made and the subgrouping into therapeutically meaningful subtypes. Current management possibilities include endoscopic treatments such as Botulinum toxin injected to the LES and pneumatic balloon dilation. Surgical treatment includes laparoscopic Heller myotomy and esophagectomy. Furthermore, in recent years, per oral endoscopic myotomy (POEM) has established itself as a principal endoscopic therapeutic alternative to the traditional laparoscopic Heller myotomy. The latest randomized trials report that POEM, pneumatic balloon dilatation, and laparoscopic Heller\'s myotomy have comparable effectiveness and complications rates. The aim of the current review is to provide a practical clinical approach to dysphagia and to shed light on the most recent improvements in diagnostics and treatment of achalasia over the last two years.
