Clinical Practice: Vocal nodules in dysphonic children

Common among children, vocal symptoms are a cause of concern for parents who seek elucidation of their diagnosis and treatment. Vocal nodules are the major cause of dysphonias in children and are related to vocal abuse. We conducted a literature review considering clinical, physiopathological, epidemiological, and histological aspects of vocal nodules, as well as diagnostic methods, highlighting the main studies addressing this issue. The controversial points of treatments were also discussed.

Perceptual and acoustic parameters of vocal nodules in children

Vocal nodules constitute the major cause of dysphonia during childhood. Auditory-perceptual and acoustic vocal analyses have been used to differentiate vocal nodules from normal voice in children.Purpose: To study the value of auditory-perceptual and acoustic vocal analyses in assessments of children with nodules.Design: Diagnostic test study.Patients and interventions: A comparative study was carried out including 100 children with videolaryngoscopic diagnosis of vocal nodules (nodule group-NG); and 100 children without vocal symptoms and with normal videolaryngoscopic exams (control group-CG). The age range of both groups was between 4 and 11 years. All children underwent auditory-perceptual vocal analyses (GRBASI scale); maximum phonation time and s/z ratio were calculated, and acoustic vocal analysis (MDVP software) were carried out.Results: There was no difference in the values of maximum phonation time and s/z ratio between groups. Auditory-perceptual analysis indicated greater compromising of voice parameters for NG, compared to CG: G (79 versus 24), R (53 versus 3), B (67 versus 23) and S (35 versus 1). The values of acoustic parameters jitter, PPQ shimmer, APQ, NHR and SPI were higher for NG for CG. The parameter f0 did not differ between groups.Conclusion: Compromising of auditory-perceptual (G, R, B and S) and acoustic vocal parameters (jitter, PPQ shimmer, APQ, NHR and SPI) was greater for children with nodules than for those of the control group, which makes them important methods for assessing child dysphonia.

Qualidade de frutos de tomate ‘giuliana’ tratados com produtos de efeitos fisiológicos

The present work evaluated the effect of strobilurins, boscalid, plant growth regulators and vegetal extracts on the physico-chemical quality of tomato fruits (Solanum lycopersicum L.), hybrid Giuliana. The fruits from each treatment were selected and separated in 4 repetitions: control, pyraclostrobin, boscalid, pyraclostrobin + boscalid, IBA + GA(3) + kinetin, GA(4+7) + benzylaminopurine and vegetal extract. The first application was carried out at 30 days after transplant and the following at every 15 days. The evaluations were: weight loss, titratable acidity (TA), soluble solids (SS), SS/TA relation, pH, ascorbic acid content, texture, total soluble sugars (TSS), activity of pectin methyl esterase (PME) and polygalacturonase (PG). The SS content, responsible for fruit flavor, varied accordingly to the treatment, being highest for GA(4+7) + benzylaminopurine and lowest for the control. The same occurred regarding the SS/AT relation. The fruits were kept on the shelf for 9 days, at room temperature, being that at the end of this period several treatments still presented fruit in optimal consumption conditions, notably the boscalid treatment, which presented lowest weight loss, followed by pyraclostrobin. Therefore, it can be concluded that the application of the treatments did not modify the values for pH, AT and AST of the fruits. The highest PME activity was observed for the treatments with boscalid and the mixture of boscalid and pyraclostrobin, while the lowest PG activity occurred in the control and the pyraclostrobin treatment, indicating that some products accelerated the process of demethylation of pectins by PME, facilitating the action of PG.

Diabetic peripheral neuropathy in ankles and feet: muscle strength and plantar pressure

This study aims to evaluate and correlate the vascular, sensory and motor components related to the plantar surface in individuals with diabetic peripheral neuropathy. 68 patients were categorized into two groups: 28 in the neuropathic group and 40 in the control group. In each patient, we assessed: circulation and peripheral perfusion of the lower limbs; somatosensory sensitivity; ankle muscle strength; and pressure on the plantar surface in static, dynamic and gait states. We used the Mann-Whitney test and analysis of variance (ANOVA and MANOVA) for comparison between groups, and performed Pearson and Spearman linear correlations amongst the variables (P < 0.05). The somatosensory sensitivity, peripheral circulation and ankle muscle strength were reduced in the neuropathic group. In full peak plantar pressures, no differences were seen between groups, but differences did appear when the foot surface was divided into regions (forefoot, midfoot and hindfoot). In the static condition, the plantar surface area was greater in the neuropathic group. In the dynamic state, peak pressures in the neuropathic group, were higher in the forefoot and lower in the hindfoot, as well as lower in the hindfoot during gait. There were positive or negative correlations between the sensitivity deficit, dorsal ankle flexor strength, plantar surface area, and peak pressure by plantar region. The sensitivity deficit contributed to the increased plantar surface area.
