The morphometry of the laryngeal phonatory system - base of the anatomical study of the voice aptitudes.

Speaking is one of the characteristics of the human race and the main factor that has marked our progress over time. The singing voice is the crowning of the speech act and the main component of the lyrical manifestation of personality. Doctors in various fields, but especially anatomists have been concerned about discovering how the voice and the substrate of its variability are formed, but these aspects have not yet been fully deciphered. This study is the starting point in our research on the phonation system, organized on three levels: laryngeal, oral, palatinal, pharyngeal, epiglottal and nasal. We performed the dissection of seven embalmed anatomical parts, on which, we made measurements of the anatomical elements involved in the phonation. We performed the same measurements on a batch of seven adults investigated by magnetic resonance imaging (MRI). The results were entered into the statistical calculation formulas and compared with each other and with the literature. The results of the study show that certain values resulting from the calculation formulas remain constant and others vary greatly from each individuals and gender.

[Voice exploratory methods into professional vocal singers]. / Metode de explorare a vocii la solistii profesionisti.

The aims of this study was to evaluated methods of voice explored to professional vocal singers. The modern methods microlaryngoscopy, stroboscopy, electroglottography are presented and comparatively evaluated with classic explorations, as direct and indirect laryngoscopy.

[Biofeedback in young singer vocal training]. / Biofeedback-ul in antrenamentul vocal al tinerilor cântareti.

UNLABELLED: Biofeedback therapy is a learning process that is based on "operant conditioning" techniques. AIM: To estimate the significance of biofeedback to an accurate and faster control of singing voice emission. RESULTS: Significantly, it was discovered that professional singers active in performing of both classical and music theatre repertoire with regard to the visual-kinesthetic effect of melodic contour in musical notation as it affect vocal timbre. The results of the study also indicate that the development of new technology for youth singer vocal training, may be useful to these singers.

[The gastro-esophageal reflux disease and its psycho-somatic component]. / Boala de reflux gastroesofagian si componenta psihosomatica.

Different factors may be involved in the occurrence of gastro-esophageal reflux disease (GERD) symptoms. This review presents the importance of psychic factors in GERD symptom genesis, especially in patients with no esophagitis. In addition, these factors could be involved in the pharmacological therapy, with educational and behavioral implications increasing the cost-efficacy of the therapy.

[Gastroesophageal reflux involvement in ENT disorders]. / Implicarea bolii de reflux gastroesofagian in patologia orl.

It is admitted that gastroesophageal reflux patients may presents ear, nose, and throat (ENT) symptoms and signs, condition known as laryngo-pharyngeal reflux. It is estimated that as many as 10% of patients presenting to an ENT specialist have a clinical condition that might be attributed to gastroesophageal reflux. The diagnosis is challenging since no laryngeal signs are pathognomonic. A combination of ENT and esophageal symptoms and signs may suggest the necessity of further investigations. Adapted 24h pH study or better an esophageal impedance study may reveal the involvement of gastroesophageal reflux. Alternatively, a short trial with omeprazole or another proton pump inhibitor may be the simplest way for diagnosis. The standard treatment for gastroesophageal reflux is the valid treatment for these patients.

[Significance of auditory and kinesthetic feedback in vocal training of young professional singers (students)]. / Importanta feedback-ului auditiv si a celui kinestezic în antrenamentul vocal al tinerilor artisti lirici.

The study was to estimate the significance of auditory and kinesthetic feedback to an accurate control of fundamental frequency (F0) in 18 students beginning a professional singing education. The students sing an ascending and descending triad pattern covering their entire pitch range with and without making noise in legato and staccato and in a slow and fast tempo. F0 was measured by a computer program. The interval sizes between adjacent tones were determined and their departures from equally tempered tuning were calculated, the deviation from this tuning were used as a measure of the accuracy of intonation. Intonation accuracy was reduced by masking noise, by staccato as opposed to legato singing, and by fast as opposed to slow performance. The contribution of the auditory feedback to pitch control was not significantly improved after education, whereas the kinesthetic feedback circuit was improved in slow legato and slow staccato tasks. The results support the assumption that the kinesthetic feedback contributes substantially to intonation accuracy.
