· Congenital cytomegalovirus (CMV) infection is among the most common causes of nongenetic sensorineural hearing loss.
· Congenital CMV is initially treated with intravenous ganciclovir for 2–6 weeks and switched to oral valganciclovir, or with oral valganciclovir for the entire 6-month period.
· Infants with congenital CMV require periodic monitoring of absolute neutrophil count, platelet count, and blood urea nitrogen, creatinine, liver function tests, audiological, ophthalmological, and developmental tests during antiviral medication.

Phenylketonuria, an autosomal recessive disease that results from the inability to metabolize phenylalanine, is currently treated with medical nutrition therapy. New treatment approaches such as tetrahydrobiopterin, glycomacropeptide, large neutral amino acids, pegvaliase, and gene therapy significantly impact disease management and dietary enrichment. This article also reviews animal and human studies that have evaluated the efficacy and safety of these new protein substitutes.

The peripartum period is an important transmission time for human T-cell lymphotropic virus-1 (HTLV-1) infection, mainly via breastfeeding and partly through the placental tissues of carrier mothers. Although most HTLV-1–infected individuals are asymptomatic, fetal and childhood infections often result in several diseases with disappointing treatment outcomes. An estimated HTLV-1 burden in Nigeria among perinatal women must be determined to enable rational planning of a comprehensive health care intervention.

-
· An imbalance of the gut microbiota with a relative increase in Firmicutes versus Bacteroidetes is associated with the pathogenesis of obesity.
· Dysbiosis is associated with microbial genes associated with short-chain fatty acids (SCFA) production and increased colonic SCFA levels. SCFAs have also been shown to regulate appetite and satiety hormones, which can affect food intake and energy balance.
· A dietary high-fat intake is reportedly associated with increased plasma lipopolysaccharide. Altered Toll-like receptor-4 signaling leads to propagating the cascade of further inflammation and promoting insulin resistance.

Breastfeeding and it's tolerance are the positive indicators for preterm babies. Placing the preterm infant in the right lateral or prone position after feed had lesser gastric residual volume compared to placing them in left lateral or supine positions. The post-feed position is a vital element in enhancing feeding tolerance, mechanical functions of the gastrointestinal tract and the overall development of preterm infants.

Gastrointestinal (GI) allergies are divided into immunoglobulin E (IgE)-mediated, non-IgE-mediated, and mixed types. In addition to non-IgE-mediated, overlapping eosinophilic GI disorders (EGIDs) have increased in Japan. EGIDs, a mixed-type allergy category, include eosinophilic esophagitis (EoE) and non-EoE EGIDs. The number of EoE cases has increased in Western countries, followed by Asian countries. Recent GI allergies may also be associated with type 2 inflammation.

· Eosinophilic gastrointestinal disease (EGID) is uncommon, with a prevalence of 1–30/100,000 in the general population; however, it is increasing worldwide.
· The diagnosis of EGID is based on histopathological findings of endoscopic mucosal biopsy in which tissue eosinophils are counted in each gastrointestinal tract segment of patients with chronic or recurrent gastrointestinal symptoms.
· Individualized treatment strategies, including adequate dietary and pharmacological therapy, may help improve outcomes of children with EGID.
