ABSTRACT BACKGROUND: Attention deficit hyperactivity disorder (ADHD) has a prevalence of 5.3% among children and adolescents. It is characterized by attention deficit, hyperactivity, and impulsivity. OBJECTIVE: We aimed to conduct a survey involving pediatric neurologists in the management of ADHD and compare the results with the current literature and guidelines. DESIGN AND SETTING: Descriptive analytical study of a virtual environment, was used Test of equality of proportions for comparison between two groups of pediatric neurologists (working as specialists for > 6 versus ≤ 6 years), with a significance level of P = 0.05. METHODS: This cross-sectional study used a virtual questionnaire covering the steps in the diagnosis and treatment of children with ADHD. The inclusion criteria were professionals who had completed their residency/specialization in pediatric neurology and clinical neurologists working in pediatric neurology. RESULTS: Among the 548 electronic invitations sent, 128 were considered valid. For all participants, the diagnosis was clinically based on the disease classification manuals. Combination treatment promotes improvement of symptoms (96.9%). Among psychostimulants, short-acting methylphenidate was the most commonly prescribed medication (85.2%). Headache was the most common side effect (77.3%). Altogether, 73.4% of the participants requested laboratory tests, 71.1% requested an electrocardiogram, and 42.2% requested an electroencephalogram. Pediatric neurologists working as specialists for ≤ 6 years had more frequent referrals to psycho-pedagogists for diagnosis (P = 0.03). CONCLUSIONS: The participants complied with clinical guidelines, emphasizing the relevance of diagnostic manuals and treatment guidelines for an eminently clinical situation and enabling uniformity in quality treatment.

CONTEXTO E OBJETIVO: A subnutrição é uma das causas das alterações no metabolismo celular. A orelha interna possui poucas reservas energéticas e alto metabolismo. O objetivo deste estudo foi de analisar se a subnutrição em idade precoce está relacionada a prejuízos em habilidades do processamento auditivo e a alterações auditivas.TIPO DE ESTUDO E LOCAL: Estudo de coorte retrospectivo conduzido em hospital público terciário.MÉTODOS: Participaram 45 crianças divididas em: G1, crianças que tiveram o diagnóstico de subnutrição nos dois primeiros anos de vida; G2, crianças sem histórico de subnutrição, mas com dificuldades de aprendizagem; G3, crianças sem histórico de subnutrição e sem dificuldades escolares. Realizou-se a timpanometria, audiometria tonal limiar e o teste de SSW [Staggered Spondaic Word] (processamento auditivo). Para a inferência estatística, usou-se o Kruskal-Wallis (α = 5%) e o teste igualdade de proporções entre duas amostras (α = 1,7%).RESULTADOS: Nenhuma das 45 crianças participantes neste estudo apresentou deficiência auditiva, porém em seis das oito frequências avaliadas, as crianças do G1 apresentaram limiares auditivos rebaixados quando comparadas às de outros grupos. No teste que avaliou o processamento auditivo, constatou-se que 100% das crianças do G1 possuem alteração do processamento auditivo, e que G1 e G2 possuem proporção semelhante de presença de alterações (valor de P: G1/G2 = 0,1; G1/G3 = > 0,001; G2/G3 = 0,008).CONCLUSÕES: A subnutrição em idade precoce causou rebaixamento nos níveis de audição, apesar de este prejuízo auditivo não ser considerado como deficiência auditiva. Todas as crianças deste grupo possuem alterações em habilidades do processamento auditivo.

CONTEXT AND OBJECTIVE: Malnutrition is one of the causes of changes in cell metabolism. The inner ear has few energy reserves and high metabolism. The aim of this study was to analyze whether malnutrition at an early age is related to impairment of auditory processing abilities and hearing abnormalities.DESIGN AND SETTING: Retrospective cohort study conducted in a tertiary public hospital.METHODS: 45 children participated, divided as follows: G1, children diagnosed with malnutrition in their first two years of life; G2, children without history of malnutrition but with learning difficulties; G3, children without history of malnutrition and without learning difficulties. Tympanometry, pure-tone audiometry and the Staggered Spondaic Word (SSW) test (auditory processing) were performed. Statistical inferences were made using the Kruskal-Wallis test (α = 5%) and the test of equality of proportions between two samples (α = 1.7%).RESULTS: None of the 45 children participating in this study presented hearing deficiencies. However, at six of the eight frequencies analyzed, the children in G1 presented hearing thresholds lower than those of the other groups. In the auditory processing evaluation test, it was observed that 100% of the children in G1 presented abnormal auditory processing and that G1 and G2 had similar proportions of abnormalities (P-values: G1/G2 = 0.1; G1/G3 > 0.001; G2/G3 = 0.008).CONCLUSIONS: Malnutrition at an early age caused lowering of the hearing levels, although this impairment could not be considered to be a hearing deficiency. Every child in this group presented abnormalities in auditory processing abilities.
