MicroRNA (miRNA) are small, noncoding RNA molecules that play pivotal roles in gene expression, various biological processes, and development of disease. MiRNAs exhibit distinct expression patterns depending on time points and tissues, indicating their relevance to the development, differentiation, and somatic growth of organisms. MiRNAs are also involved in puberty onset and fertility. Although puberty is a universal stage in the life cycles of most organisms, the precise mechanisms initiating this process remain elusive. Genetic, hormonal, nutritional, environmental, and epigenetic factors are presumed contributors. The intricate regulation of puberty during growth also suggests that miRNAs are involved. This study aims to provide insight into the understanding of miRNAs roles in the initiation of puberty by reviewing the existing research.

MicroRNAs (miRNAs) are highly conserved noncoding RNAs that regulate gene expression by silencing or degrading messenger RNAs. Many of the approximately 2,500 miRNAs discovered in humans are known to regulate vital biological processes, including cell differentiation, proliferation, apoptosis, and embryonic tissue development. Aberrant miRNA expression may have pathological and malignant consequences. Therefore, miRNAs have emerged as novel diagnostic markers and potential therapeutic targets for various diseases. Children undergo various stages of growth, development, and maturation between birth and adulthood. It is important to study the role of miRNA expression in normal growth and disease development during these developmental stages. In this mini-review, we discuss the role of miRNAs as diagnostic and prognostic biomarkers in various pediatric diseases.

Neonatal hyperinsulinism, whether permanent or transient, results in prolonged hypoglycemia, which increases the risk of hypoglycemic brain injury. Therefore, prompt diagnosis and management of hyperinsulinemic hypoglycemia is important. Drawing a “critical sample” at the time of hypoglycemia is useful for diagnosis. Genetic testing for defective insulin-regulating genes in pancreatic beta-cells might also be helpful in cases of prolonged hypoglycemia. High-calorie feeding or glucose infusion is necessary to maintain normoglycemia. Diazoxide is the treatment of choice for hyperinsulinism and should be continued until the hypoglycemia resolves. We describe a case of transient neonatal hyperinsulinemia hypoglycemia in a small-for-gestational-age preterm infant who underwent diazoxide treatment and achieved a favorable outcome.
