Summary
This study presents the youngest case of non-syndromic congenital atlantoaxial dislocation in an infant. Management challenges and unique radiological findings in this rare condition are discussed.
Area of Science:
- Pediatric Neurology
- Orthopedic Surgery
- Medical Imaging
Background:
- Congenital atlantoaxial dislocation (CAAD) is a rare spinal malformation.
- Early presentation in infancy poses unique management challenges.
Observation:
- A 9-month-old female infant presented with progressive quadriparesis and respiratory failure.
- This case represents the youngest reported instance of non-syndromic CAAD.
- The infant exhibited a unique combination of lateral, rotatory, and antero-posterior atlantoaxial dislocation.
Findings:
- Atypical clinical presentation in infants.
- Unique radiological findings specific to early-onset CAAD.
- Limited therapeutic options for managing CAAD in very young children.
Implications:
- Highlights the need for early diagnosis and tailored management strategies for CAAD.
- Contributes to understanding the spectrum of congenital spinal disorders.
- Informs clinical decision-making for rare pediatric spinal conditions.

01:24Data Reporting and Recording
5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

An Incident or Occurrence Report in a healthcare setting is a crucial document used to record any unexpected occurrence that may or may not have affected a patient, employee, or visitor. Such reports are critical to improving patient safety and include all details leading up to and including the event.

16.9K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
