Opis:
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. The most frequent type of dysphonia is hyperfunctional dysphonia, rarer – hypofunctional type. Aim: The aim of this study is an analysis of voice quality and diagnosis of clinical type of psychogenic dysphonia. Material and methods: The analyzed group consisted of 50 patients with voice disorders treated in 2017 and the control group – 30 people with physiological voice. In the diagnosed group 60% of patients were treated for neurosis, 12% due to depression, the others reported conflict situations. In the diagnosis of clinical type of psychogenic dysphonia GRBAS scale was used, maximum phonation time (MPT) and type of breathing were assessed. The visualisation of the larynx was performed using High Speed Digital Imaging (HSDI) technique. The parametric acoustic evaluation of voice was conducted. Results: The most often clinical type of psychogenic dysphonia was hyperfunctional dysphonia, rarer hypofunctional type and vestibular voice. Dysphonia occurred the most often in women during the highest professional activity period. In the diagnosis of clinical type HSDI technique was especially useful allowing to visualization of the real vocal fold vibration and objective differentiation of hyper- and hypofunctional dysphonia. The acoustic analysis of the voice objectively confirmed the presence non-harmonic components – noise generated in the glottis in hypofunctional dysphonia. Disturbances in the way and breathing type caused irregularities in respiratory-phonic and articulation coordination.

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. The image of vocal folds was recorded with a rate of 4000 frames per second. Postoperative material of the larynx was prepared in a routine way and observed in transmission electron microscope OPTON 900–PC. Results. HSDI technique allows to assess the real vibrations of vocal folds and determine many parameters. The results of TEM in the postoperative material showed destruction of epithelial cells with severe vacuolar degeneration, the enlargement of intercellular spaces and a large number of blood vessels in the stroma, which indicates the presence of oedematous-hypertrophic changes of the larynx. Discussion. The ultrastructural assessment confirm the particular usefulness of HSDI method in the diagnosis of organic dysphonia in a form of oedematous-hypertrophic changes. Key words: High-Speed Digital Imaging, oedematous-hypertrophic changes, vocal fold mucosa, larynx

Opis:
Various aspects of merging the chosen presentation methods (choropleth and diagram) on one map are discussed in the article. Attention is focused on the graphic match of both methods, on the character and reference of data presented in this manner. Examples of such matches are shown, from the simplest application to complicated anamorphic presentations.

Opis:
Examples of unusual and unconventional graphic solutions which we can often find in the times of fast developing computer technology are discussed in the article. Many of them are suggested by various GIS programs, few of them may be found in the press or on the Internet. This means that their users are people who are not associated with cartography and who are not familiar with the framework of cartographic methods.

Opis:
Objectives: The assessment of the neurotoxic effect of arsenic (As) and its inorganic compounds is still the subject of interest due to a growing As application in a large array of technologies and the need to constantly verify the principles of prevention and technological parameters. The aim of this study was to determine the status of the nervous system (NS) in workers exposed to As at concentrations exceeding hygiene standards (Threshold Limit Values (TLV) – 10 μg/m³, Biological Exposure Index (BEI) – 35 μg/l) and to analyze the relationship between the NS functional state, species of As in urine and As levels in the workplace air. Material and Methods: The study group comprised 21 men (mean age: 47.43±7.59) employed in a copper smelting factory (mean duration of employment: 22.29±11.09). The control group comprised 16 men, matched by age and work shifts. Arsenic levels in the workplace air (As-A) ranged from 0.7 to 92.3 μg/m³; (M = 25.18±28.83). The concentration of total arsenic in urine (Astot-U) ranged from 17.35 to 434.68 μg/l (M = 86.82±86.6). Results: Syndrome of peripheral nervous system (PNS) was manifested by extremity fatigue (28.6%), extremity pain (33.3%) and paresthesia in the lower extremities (33.3%), as well as by neuropathy-type mini-symptoms (23.8%). Electroneurographic (ENeG) tests of peroneal nerves showed significantly decreased response amplitude with normal values of motor conduction velocity (MCV). Stimulation of sural nerves revealed a significantly slowed sensory conduction velocity (SCV) and decreased sensory potential amplitude. Neurophysiological parameters and the results of biological and environmental monitoring showed a relationship between $\text{As}^\text{tot}$, $\text{As}^\text{III}$ (trivalent arsenic), the sum of iAs ($\text{As}^\text{III}+\text{As}^\text{V}$ (pentavalent arsenic))+MMA (monomethylarsonic acid) concentration in urine and As levels in the air. Conclusions: The results of the study demonstrate that occupational exposure to inorganic arsenic levels exceeding hygiene standards (TLV, BEI) generates disorders typical of peripheral neuropathy.
