Insights
Apparent life-threatening events (ALTEs) in infants pose diagnostic challenges. This review highlights the need for better risk identification and investigation strategies to avoid missing serious conditions in well-appearing infants.
Area of Science:
- Pediatrics
- Neonatology
- Emergency Medicine
Background:
- Apparent life-threatening events (ALTEs) are common in infants and pose diagnostic challenges.
- These events can mask serious underlying conditions and strain medical resources.
- Evaluating well-appearing infants with ALTEs requires careful consideration of severe diagnoses.
Purpose of the Study:
- To review the assessment of well-appearing infants presenting with ALTEs.
- To focus on identifying serious potential diagnoses including infections, seizures, abuse, metabolic disorders, and severe apnea.
- To highlight challenges in evaluating the youngest infants (under 2 months).
Main Methods:
- Literature review focusing on the evaluation of infants with ALTEs.
- Analysis of diagnostic challenges and the need for risk stratification.
- Examination of serious differential diagnoses for well-appearing infants.
Main Results:
- Physicians face significant difficulties in evaluating infants with ALTEs, particularly those under 2 months.
- Less severe forms of metabolic disorders, seizure disorders, and child abuse may only be diagnosed upon recurrent events.
- There is a need for prospective studies to identify risk factors and guide investigations.
Conclusions:
- Accurate diagnosis of serious conditions in infants with ALTEs remains a challenge.
- Prospective studies are crucial for developing evidence-based guidelines for infant ALTE evaluation.
- Improved diagnostic strategies are needed to prevent missed diagnoses and ensure appropriate infant care.
Abstract:
Apparent life-threatening events (ALTEs), because of their prevalence as well as their potential to hide serious diseases and consume significant medical resources, remain a challenge for physicians caring for infants. In this review, we focused on the assessment of the well-appearing infant for the most serious diagnoses, namely serious bacterial infections, seizure disorders, child abuse, metabolic disorders and severe apnoea with hypoxemia. Our extensive review of the literature has highlighted the difficulties physicians are facing in this evaluation, especially for the youngest infants (aged less than 2 months). Large-scale prospective studies are needed to identify risk factors and to guide physicians as to who should be investigated and the minimal investigation needed to avoid missing such conditions as serious bacterial infection, abusive head injury or repeated severe cardiorespiratory events. While infants with severe forms of metabolic disorders typically present with evident signs and symptoms, less severe forms of metabolic disorders, seizure disorders, and some forms of child abuse will often be diagnosed only when recurrent events are investigated.
