Terapia antirretroviral em crianças e adolescentes infectados pelo HIV: o que sabemos após 30 anos de epidemia

Auditory-perceptual and acoustic analysis of voices of HIV-infected children

PURPOSE

To compare vocal and acoustic parameters of HIV-infected children and non-HIV-infected children.

METHODS

Vocal samples were submitted to auditory-perceptual and acoustic analysis. Samples of the sustained vowel /ε/ and continuous speech of 74 children between 6 and incomplete 12 years old were analyzed, divided into two groups: 37 HIV-infected children (GHIV) and 37 non-HIV-infected children, the control group (CG), age and gender-matched and without previous vocal evaluation; they were all prepubescent by the Tanner Stages (MS, 2014). The children had their voices recorded and analyzed by VoxMetria 5.1, in the period between 2014 and 2015. The auditory-perceptual analysis assessed the overall degree of the vocal quality and was performed using a 100-point visual analogue scale, transformed into a 4 point numerical scale (0 = no vocal deviation and 4 = severe vocal deviation). The acoustic evaluation was based on the analysis of the vocal sample distribution in the Phonatory Deviation Diagram (PDD). The research was approved by the Ethics Committee under the number 122.746.

RESULTS

In the auditory-perceptual analysis, most children of both groups were evaluated as with no vocal deviation. No difference between the groups was found in the acoustic analysis using the PDD; most voice samples were within the normality area, in the quadrant 1, with a spread density distribution and a vertical shape.

CONCLUSION

HIV-infected children presented similar vocal quality to children without the illness, both for the perceptual-auditory and acoustic evaluation.

Evaluation of the quality of primary health care for children and adolescents with HIV: PCATool-Brasil

OBJECTIVE

Assess the overall score of the Primary Health Care in municipalities where children and adolescents living with HIV reside, according to the PCATool-Brazil instrument, professional version.

METHODS

Quantitative study with 527 professionals in 25 municipalities where children and adolescents living with HIV reside. Data collection took place between March and August 2014, by applying PCATool-Brazil instrument, professional version. In the data analysis, we used Pearson's chi-square test, the Mann Whitney test and Poisson regression. All ethical aspects were respected.

RESULTS

The overall assessment of the Basic Health Unit (BHU) and the Family Health Strategy's (FHS) service quality was satisfactory (6.80). When BHU and FHS were compared, only the latter showed a high score (7.06).

CONCLUSIONS

Despite the satisfactory overall score, the need to expand the FSH coverage, and encourage the promotion of competitive public service examinations and the qualification of these professionals.
