The Zika virus can induce a disruptive sequence in the fetal brain and is manifested mainly by microcephaly. Knowledge gaps still exist as to whether the virus can cause minor disorders that are perceived later on during the first years of life in children who are exposed but are asymptomatic at birth. In this case series, we describe the outcomes related to neurodevelopment through the neurological assessment of 26 non-microcephalic children who had intrauterine exposure to Zika virus. Children were submitted for neurological examinations and Bayley Scales-III (cognition, language, and motor performance). The majority (65.4%) obtained satisfactory performance in neurodevelopment. The most impaired domain was language, with 30.7% impairment. Severe neurological disorders occurred in five children (19.2%) and these were spastic hemiparesis, epilepsy associated with congenital macrocephaly (Zika and human immunodeficiency virus), two cases of autism (one exposed to Zika and Toxoplasma gondii) and progressive sensorineural hearing loss (GJB2 mutation). We concluded that non-microcephalic children with intrauterine exposure to Zika virus, in their majority, had achieved satisfactory performance in all neurodevelopmental domains. One third of the cases had some impairment, but the predominant group had mild alterations, with low occurrence of moderate to severe disorders, similar to other studies in Brazil.
Infections with Flavivirus in pregnant women are not associated with vertical transmission. However, in 2015, severe cases of congenital infection were reported during the Zika virus outbreak in Brazil. More subtle infections in children born to mothers with ZIKV still remain uncertain and the spectrum of this new congenital syndrome is still under construction. This study describes outcomes regarding neurodevelopment and neurological examination in the first years of life, of a cohort of 77 children born to pregnant women with ZIKV infection in Manaus, Brazil, from 2017 to 2020. In the group of normocephalic children (92.2%), most showed satisfactory performance in neuropsychomotor development, with a delay in 29.6% and changes in neurological examination in 27.1%, with two children showing muscle-strength deficits. All microcephalic children (5.2%) evolved with severe neuropsychomotor-development delay, spastic tetraparesis, and alterations in the imaging exam. In this cohort, 10.5% of the children had macrocephaly at birth, but only 2.6% remained in this classification. Although microcephaly has been considered as the main marker of congenital-Zika-virus syndrome in previous studies, its absence does not exclude the possibility of the syndrome. This highlights the importance of clinical follow-up, regardless of the classification of head circumference at birth.
Resumo: Demonstra-se um caso de paquidermatoglifia adquirida em paciente do sexo masculino, de 67 anos, associada a carcinoma gástrico avançado. Trata-se de síndrome paraneoplásica com manifestações cutâneas que podem ser comparadas à superfície rugosa do estô-mago bovino. Palavras-chave: Ceratodermia palmar e plantar; Neoplasias gástricas; Síndromes paraneoplásicas Paquidermatoglifia adquirida (PA) é ceratodermia palmoplantar não familiar, manifestação cutânea rara caracterizada por espessamento aveludado, acompanhado de aumento pronunciado das linhas e sulcos das superfícies palmar e plantar.
1,2Pertence ao espectro das síndromes paraneoplásicas papuloescamosas e está associada usualmente à neoplasia de órgãos internos, podendo eventualmente ocorrer como manifestação clínica independente.1,3 A erupção pode regredir ou eventualmente desaparecer com o tratamento da neoplasia e reaparecer com a recorrência da malignidade. 1 Tripe, em inglês, é iguaria preparada a partir do estômago bovino. A região palmar dos pacientes acometidos possui aspecto rugoso que pode ser comparado à superfície aveludada do estô-mago bovino. 1 A patogenia da condição ainda não está definitivamente estabelecida. Sabe-se que pode estar relacionada a produtos liberados por células cancerosas, sendo o fator de crescimento alfa (TGF-α) e o fator de crescimento epidérmico os mais prováveis.
