The estimated birth prevalence for anophthalmia is approximately 3 per 100000 live births, and for microphthalmia, it is around 14 per 100000 live births.

Anophthalmia and microphthalmia (A/M) are part of a phenotypic spectrum alongside ocular coloboma, hypothesized to share a common genetic basis.

There is limited data on pediatric ATDIH, and much of the management practices are extrapolated from adult experiences. This article provides a comprehensive overview of the incidence, risk factors, clinical presentation, and management strategies for ATDIH in children. Pyrazinamide, isoniazid, and rifampicin are the most hepatotoxic first-line antituberculosis therapy (ATT). Though pyrazinamide has the highest potential for ATDIH, isoniazid is most frequently implicated. Hepatotoxicity typically manifests within the first 2-8 weeks of treatment, particularly during the intensive phase. Risk factors include younger age, female gender, malnutrition, hypoalbuminemia, and baseline liver dysfunction. Extra-pulmonary TB, particularly tuberculous meningitis, and concomitant hepatotoxic medications such as antiretro viral therapy or antiepileptic drugs further increase susceptibility. Genetic predisposition, including N-acetyltransferase 2 and cytochrome P4502E1 polymorphisms and specific HLA alleles also contribute to the increased risk. Clinically, ATDIH ranges from asymptomatic transaminase elevation to severe acute liver failure (ALF), necessitating prompt recognition and intervention. Diagnosis relies on the temporal association of liver injury with ATT initiation, supported by liver function tests, improvement upon ATT cessation, and recurrence upon reintroduction. Management involves discontinuing hepatotoxic drugs, initiating non-hepatotoxic regimens, and sequential reintroduction of ATT under close monitoring. For children with ALF, care in a tertiary center with liver transplantation expertise is essential. While pediatric ATDIH generally has favorable outcomes with timely intervention, delays can result in significant morbidity and mortality. Improved understanding of risk factors, vigilant monitoring protocols, and standardized pediatric management strategies are critical for optimizing outcomes in pediatric ATDIH.</p>","PeriodicalId":75338,"journal":{"name":"World journal of clinical pediatrics","volume":"14 2","pages":"101875"},"PeriodicalIF":0.0,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11947884/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144259597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is the temptation to enjoy too much food that is advertised as delicious and to eat too little healthier food. An increasingly sedentary lifestyle makes physical activity voluntary, no longer based on the daily need for physical activity in rural production. This is a serious medical problem, as today's young people are threatened tomorrow (and sometimes, already today) by cardiovascular disease and type 2 diabetes mellitus, later by further challenges including arthritis, stroke, and more. But this is a challenge far beyond medicine. Young people need to be empowered to distinguish between good and bad lifestyles and be strengthened in their willingness to make an effort for future health. It may not seem very sexy to eat mostly fruits and high-fiber traditional foods instead of hamburgers, snacks, sweets, or to eat in posh restaurants. Everyone needs a certain resistance to advertising today, whether they grow up in Nigeria, Europe or anywhere else.
