Exome sequencing unravels complex genetic diagnoses in growth disorders

In an article published in the Journal of Pediatrics, researchers based in Brazil describe the case of a nine-year-old boy admitted to hospital with multiple symptoms and overlapping conditions that made diagnosis difficult, such as short stature, thin tooth enamel (dental enamel hypoplasia), moderate mental deficiency, speech delay, asthma, mildly altered blood sugar, and a history of recurring infections in infancy.

Added calcium and phosphate in fluoride varnishes no silver bullet for fighting kids' tooth decay, study finds

The study explores the effectiveness of sodium fluoride varnishes with added calcium and phosphate versus conventional varnishes in reducing harmful bacteria in preschool children's mouths. Results indicate no significant difference between the two types of varnishes in controlling bacterial growth, calling for more research on effective ways to combat early childhood caries.
