RESUMO
BACKGROUND: MicroRNAs are involved in gene regulation in several common liver diseases and may play an essential role in activating hepatic stellate cells. The role of these post-transcriptional regulators in schistosomiasis needs to be further studied in populations from endemic areas for a better understanding of the disease, the development of new therapeutic approaches, and the use of biomarkers for the prognosis of schistosomiasis. AREAS COVERED: We performed a systematic review to describe the main human microRNAs identified in non-experimental studies associated with aggravation of the disease in people infected with Schistosoma mansoni (S. mansoni) and Schistosoma japonicum (S. japonicum). Structured searches were carried out in PubMed, Medline, Science Direct, Directory of Open Access Journals, Scielo, Medcarib, and Global Index Medicus databases without time and language restrictions. This is a systematic review following the guidelines of the PRISMA platform. EXPERT OPINION: The miR-146a-5p, miR-150-5p, let-7a-5p, let-7d-5p, miR-92a- 3p, and miR-532-5p are associated with liver fibrosis in schistosomiasis caused by S. japonicum, revealing that these miRNAs that have been shown to be associated with liver fibrosis are good targets for new studies that evaluate their potential as a biomarker or even treating liver fibrosis in schistosomiasis.

Abstract Introduction: goldenhar syndrome is a rare congenital syndrome that affects the craniofacial morphogenesis. It is a complex syndrome, with heterogeneous presentation which the diagnosis can still be performed in the intrauterine through morphological ultrasound. Description: a case report of a 4-year-old male patient diagnosed with Goldenhar syndrome, along with its clinical presentation, diagnostic investigation and follow-up. Discussion: the follow-up on these patients remains a challenge, since it can affect different systems and with different presentations. The earlier the diagnosis is performed, the greater the patient's chances of having a favorable prognosis with multidisciplinary stimulation. The objective of this article is to contribute to the medical literature, in order to assist in the diagnosis and management of future cases.
Resumo Introdução: a síndrome de Goldenhar é uma síndrome congênita rara que afeta a morfogênese craniofacial. Trata-se de uma síndrome complexa, de apresentação heterogênea, cujo diagnóstico pode ser realizado ainda intra-útero através do ultrassom morfológico. Descrição: relato de caso de um paciente do sexo masculino de quatro anos, com diagnóstico de síndrome de Goldenhar, sua apresentação clínica, a investigação diagnóstica e seguimento. Discussão: o acompanhamento desses pacientes continua sendo um desafio, já que pode acometer diversos sistemas e com apresentação diversa. O diagnóstico e a estimulação multiprofissional precoce, podem levar a maiores chances de um prognóstico favorável. O objetivo deste trabalho é contribuir para a literatura médica, de forma a auxiliar no diagnóstico e conduta perante futuros casos.
