Phoniatric, Audiological, Orodental and Speech Problems in a Boy with Cardio-Facio-Cutaneous Syndrome Type 3 (CFC 3) Due to a Pathogenic Variant in - Case Study.

Cardio-facio-cutaneous syndrome 3 (CFC3) due to variants in is a rare genetic disorder manifested mainly by short stature, facial dysmorphism, abnormalities of the cardiovascular system, skin changes, and intellectual disability. The aim of the study is the evaluation of the occurrence of pathological changes in the upper respiratory tract, orthodontic disorders, as well as voice, speech and hearing abnormalities in an 11-year-old boy with CFC3 syndrome. The lack of detailed diagnostics of speech, voice and hearing disorders, as well as the degree of their severity was an inspiration to undertake research in this field.

Verbal communication disorders in psychogenic dysphonia.

Psychogenic dysphonia is defined as disturbances in voice and speech quality with emotional background with lack of organic changes in the larynx. Mental condition has significant impact on the process of producing voice, functioning of respiratoryphonatory- articulation mechanism and speech prosody. The aim of the study was visual, acoustic, perceptual assessment as well as self-assessment of voice and speech quality using subjective and objective methods in patients with psychogenic dysphonia.

Analysis of voice quality parameters in patients with vestibular voice.

Vestibular voice includes participation of larynx structures which are absent in physiological process. Vestibular phonation may be desired when vocal folds are damaged as in paralytic dysphonia, or undesired in marginal hyperfunction. Vestibular voice may result from psychogenic dysphonia - phononeurosis.

Subjective and objective assessment of voice quality in pregnancy.

During pregnancy, voice quality disorders may occur in form of: edema, dryness, nervousness. The aim of the study is subjective and objective evaluation of voice quality in pregnant women. The study included 20 women in the third trimester of pregnancy, age of 20-31 diagnosed at the Department of Clinical Phonoaudiology and Logopedics, Medical University of Bialystok.

Psychogenic voice disorders.

Introduction: Voice express the psyche and personality of a person. Psychogenic dysphonia is called Phononeurosis. Neurosis, depression or family, occupational and social conflicts are the cause of voice disturbances.

Usefulness of high-speed digital imaging (HSDI) in the diagnosis of oedematous - hypertrophic changes of the larynx in people using voice occupationally.

Introduction: The aim of the study is the evaluation of the usefulness of High-Speed Digital Imaging (HSDI) in the diagnosis of organic dysphonia in a form of oedematous-hypertrophic changes of vocal fold mucosa, morphologically confirmed by Transmission Electron Microscopy (TEM) method in patients working with voice occupationally.

Material And Methods: The group consisted of 30 patients working with voice occupationally with oedematous-hypertrophic changes of vocal fold mucosa. Parameters of vocal folds vibrations were evaluated using HSDI technique with a digital HS camera, HRES Endocam Richard Wolf GmbH.

[Effects of electrostimulation therapy in selected cases of vocal fold paralysis].

Unlabelled: Paralytic dysphonia is the most serious neurogenic pathology of voice quality. An important issue is to identify methods which support routine treatment.

Aim: The aim of the study is to assess voice quality after electrostimulation (ES) therapy in patients with paralytic dysphonia.

[Rehabilitation of phonosurgically treated patients with edematous-hypertrophic changes of larynx].

Unlabelled: Advanced change of organic dysphonia are an indication for phonosurgery. Edematous-hypertrophic changes are cause of serious disturbances of voice. High-speed digital imaging (HSDI) technique is the unique method, allowing for assessment the effects of therapy and rehabilitation.

Influence of Melatonin on the Rate of Rana pipiens Tadpole Metamorphosis In Vivo and Regression of Thyroxine-Treated Tail Tips In Vitro: (tadpole/metamorphosis/thyroxine/melatonin/tissue culture).

Metamorphosis of Rana pipiens tadpoles may be retarded when the light phase of the light/dark (LD) cycle is shortened or when thyroxine (T ) is given in the dark because melatonin peaks during the dark. Injection of premetamorphic tadpoles in spontaneous metamorphosis with melatonin (15 μg) retarded tail growth and hindlimb development on 18L:6D but had no significant effect on 6L:18D. During induced metamorphosis (30 μg/liter T ), melatonin injections retarded tail resorption on 18L:6D and accelerated it on 6L:18D, but did not affect the hindlimb.
