ABSTRACT

Neurosyphilis is an infection of the central nervous system caused by Treponema pallidum and may be symptomatic or asymptomatic in children with congenital syphilis. This study aims to describe the cortical activation pattern of a four-month-old infant with neurosyphilis using functional near-infrared spectroscopy (fNIRS). Born at term weighing 3,475 kg, she presented a Venereal Disease Research Laboratory (VDRL) test of 1:32 and changes in the cerebrospinal fluid test. She underwent treatment with crystalline penicillin for 10 days before discharge from the hospital. In the audiological evaluation, she presented normal tympanometry, otoacoustic emissions evoked by transient stimulus, brainstem auditory evoked potential with click stimulus at 80 and 30 dB nHL bilaterally. The Bayley III Scale was applied to assess language, cognition and motor development, showing delays in expressive language and broad motor skills. In the fNIRS acquisition, data were collected through 20 channels divided between the cerebral hemispheres. The /ba/ and /da/ stimuli were presented at 40 dB HL with the Psychopy software through a headphone. Data analysis used the MNE and MNE-NIRS toolboxes in the Spyder environment. The average by channel, ROI, and condition was exported for analysis. A similar theta coefficient was observed between the conditions and channels evaluated in both cerebral hemispheres, with a greater amplitude of oxyhemoglobin (HbO) being observed in the anterior position when compared to the posterior region of the temporal lobe. Therefore, this case report highlights the need to monitor the child development of babies with neurosyphilis.


A neurossífilis é uma infecção do sistema nervoso central causada pelo Treponema pallidum, podendo ser sintomática ou assintomática nas crianças com sífilis congênita. Este estudo visa descrever o padrão de ativação cortical de uma lactente de quatro meses com neurossífilis utilizando o funcional near-infrared spectroscopy (fNIRS). Nascida a termo com 3.475 Kg, apresentou teste Venereal Disease Research Laboratory (VDRL) de 1:32 e alteração no exame de líquor cefalorraquidiano. Realizou tratamento com penicilina cristalina por 10 dias antes da alta hospitalar. Na avaliação audiológica apresentou normalidade na timpanometria, emissões otoacústicas evocadas por estímulo transiente, potencial evocado auditivo de tronco encefálico com estímulo clique a 80 e 30 dB nNA bilateralmente. Foi aplicada a Escala Bayley III para a avaliação do desenvolvimento de linguagem, cognição e motor, apresentando atrasos na linguagem expressiva e no motor amplo. Na aquisição do fNIRS os dados foram coletados por 20 canais divididos entre os hemisférios cerebrais. Os estímulos /ba/ e /da/ foram apresentados a 40 dB NA com o auxílio do programa Psychopy por um fone de ouvido. A análise dos dados utilizou as toolboxes MNE e MNE-NIRS no ambiente Spyder. A média por canal, ROI e condição foi exportada para análise. Observou-se um coeficiente theta similar entre as condições e canais avaliados de ambos os hemisférios cerebrais, sendo observado maior amplitude da oxihemoglobina (HbO) na posição anterior quando comparados a região posterior do lobo temporal. Desta forma, este relato de caso evidencia a necessidade de monitoramento do desenvolvimento infantil de lactentes com neurossífilis.

ABSTRACT

Objective: To study the prevalence of risk for hearing impairment in neonates with congenital syphilis in a newborn hearing screening program. Study design: The study design is retrospective, documentary, and is cross-sectional. The sample consisted of newborns who were born between January 2019 and December 2021 and who underwent neonatal hearing screening in a public maternity hospital. Demographic data and the presence and specification of risk indicators for hearing impairment (RIHL) were collected. In retest cases, the results and the final score were also collected. For data analysis, the Kruskal-Wallis and Conover-Iman post-hoc tests were used, comparing the groups that passed and failed the hearing screening that had RIHL, using a significance level of p of <0.5. Results: Among the RIHL observed in the sample, prematurity was more frequent in newborns who passed the screening (55.26%) than in those who failed the test (45.67%). Congenital syphilis was the ninth most frequent RIHL (8.04%) among the newborns who passed the test and the 15th factor (3.03%), with the highest occurrence in those who failed the hearing screening. When comparing the two groups (pass and fail), we found significant differences (p < 0.05) between them. Conclusion: Congenital syphilis was the ninth risk indicator for the most common hearing impairment and, in isolation, did not present a risk for failure in neonatal hearing screening. Notably, congenital syphilis can cause late hearing loss during child development. Thus, there is an indication of audiological monitoring of these neonates.

ABSTRACT

PURPOSE: To determine the coverage of newborn hearing screening (NHS) and its association with the availability of speech therapists in the National Health System (SUS) and equipment in the states of Brazil in 2012 and 2018. METHODS: This is a descriptive ecological time series study with the Brazilian states and live births as units of analysis. An exploratory analysis of newborn hearing screening coverage and descriptive data analysis were performed. Spearman's correlation coefficient was used to measure the strength and direction of the association between two ranked variables. RESULTS: Coverage in Brazil increased from 24.1% to 67.6%. Better coverage was observed in the South and Southeast regions in 2012, and in the former and Mato Grosso state (MS) in 2018. The average number of speech therapists was 4.79 and 8.9 / 100,000 inhabitants in 2012 and 2018, respectively. The index of "transient evoked otoacoustic emission" equipment was below 1 / 100,000 inhabitants in the two years in all the states of the country. CONCLUSION: Screening coverage increased in Brazil, albeit below the recommended level, and is related to rising number of speech therapists in the SUS. Spatial distribution is heterogeneous throughout the country.


OBJETIVO: Verificar a cobertura da triagem auditiva neonatal e sua associação com a quantidade de Fonoaudiólogos no SUS e de equipamentos disponíveis nas unidades federativas do Brasil nos anos de 2012 e 2018. MÉTODO: O estudo é do tipo ecológico descritivo de séries temporais tendo como unidade de análise as Unidades de Federação do Brasil e os nascidos-vivos. Foi realizada a análise exploratória da cobertura da triagem auditiva neonatal e análise descritiva dos dados. O coeficiente de correlação do ranking de Spearman foi usado para medir a força e direção de associação entre duas variáveis ranqueadas. RESULTADOS: A COB no Brasil apresentou evolução de 24,1% para 67,6%. Observaram-se melhores coberturas estão nas Regiões Sul e Sudeste em 2012 e no ano de 2018 destacando-se a Região Sul e o estado do MS. A média do índice de fonoaudiólogos foi de 4,79 e 8,9/100.000 habitantes, respectivamente para os anos de 2012 e 2018. O índice da oferta de equipamentos de "Emissões Otoacústicas Evocadas Transientes" se manteve abaixo de 1/100.000 habitantes nos dois anos e em todas as unidades federativas do país. CONCLUSÃO: A cobertura da triagem apresentou um aumento no Brasil, porém ainda abaixo do recomendado e está relacionada com o aumento da inserção de fonoaudiólogos no SUS. A distribuição espacial se apresenta heterogênea em todo seu território.
