Insights

Turkey

Area of Science:

  • Medical Genetics
  • Public Health
  • Pediatrics

Background:

  • Phenylketonuria (PKU) screening is a national child health program in Turkey.
  • The program, established in 1986, has expanded to cover all major cities.
  • Collaboration exists between the Ministry of Health and university hospitals.

Purpose of the Study:

  • To report on the outcomes of phenylketonuria screening in Turkey.
  • To identify challenges in the screening and management of PKU cases.
  • To recommend improvements for the national screening program.

Main Methods:

  • Guthrie test used for screening.
  • Screening conducted at the Hacettepe Screening Center in Ankara.
  • Data analyzed from 1,605,582 screened newborns.

Main Results:

  • 383 cases of persistent hyperphenylalaninemia detected (1:4,172 incidence).
  • Classified cases: 216 classical PKU, 102 mild-moderate PKU, 58 mild hyperphenylalaninemia.
  • Identified issues: sample collection, early discharge, case follow-up, and dietary compliance.

Conclusions:

  • The national PKU screening program has identified a significant number of cases.
  • Challenges in sample collection, follow-up, and treatment adherence require addressing.
  • An intersectoral approach is needed to enhance newborn screening and management, potentially including hypothyroidism.

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
