Pediatric Pathology, Disorders and Illnesses Flashcards
• What is the definition of Microcephaly?
• >2 standard deviations below the mean for the age/sex
• What can cause Microcephaly?
• Can occur d/t chromosomal abnormalities, infections, metabolic disorders and or neurologic insult
• How do you diagnose Microcephaly?
• CT/MRI may aid in dx
• What is the treatment of Microcephaly?
• Treatment is supportive and or aimed at underlying etiology
o Macrocephaly:
• Head circumference>2 standard deviations above the mean for age/sex
• What is the cause of Macrocephaly?
- Rapid head growth suggest increased ICP (mist likely caused by ICP, extra axial fluid collection or neoplasms)
- Normal growth rate a/w Microcephaly can be d/t familial Macrocephaly or true megalocephaly (nerurofibromatosis)
- Preterm infants can have Microcephaly d/t “catch up growth”
• How do you dx Microcephaly?
• CT/MRI study of choice to t/o structural causes.
• What is Plagiocephaly?
• Asymmetry of the cranial vaults
• What is Brachycephaly?
• Asymmetry of the cranial vaults
• What is the most common cuase of Brachycephaly?
- Supine sleeping position
- May also occur d/t pathology including trticollis or lack of stimulation
- May occur d/t Craniosynostosis
• Dx and Treatment of Brachycephaly
• Rarely requires skill film or consult
• What has led to earlier detection of hearing defects?
• Universal screening
• Hearing loss in children can significantly impair what?
• A Childs ability to communicate and will delay academic, social and emotional development.
• Pts with + hearing screen should what?
- Be referred for further audiologic evaluation
* Early intervention is critical
• What is the most common cause of hearing loss in children?
• Conductive hearing loss
• What pathology would suggest the need for assessment of conductive hearing loss?
• Recurrent otitis media or middle ear effusion lasting > 3 mo should have hearing and language skills assessment
• Treatment of conductive hearing loss?
• Middle ear fluid can be treated with placement of Tympanostomy tubes
• Causes of sensorineural hearing loss?
- May be congenital or acquired
- Risk factors for neonatal hearing loss include positive family hx, low birth weight, low apgar scores, craniofacial abnormalities, hypoxia, in-utero infections, hyperbilirubinemia requiring exchange transfusion, mechanical ventilation >5 dayls
• How is sensorineural hearing loss treated?
• With amplification
o Cochlear implantation may be option for pts with severe defects
o Foreign Body in the Ear Canal
• How do dx a FB?
• Visualization
how do you remove a FB in the ear?
- Most Fb can safely be removed by PCP utilizing techniques including irrigation of instrumentation under direct visualization
- If concern regarding removal refer to ENT
• What FB od the ear MUST be refereed to ENT?
- Button Batteries
- Penetrating FB
- Fb associated with injury/ trauma
• How will a FB in the nasal cavity present?
• Often asymptomatic but may be a/w mucopurulent nasal draining, foul odor, epistaxis, nasal obstruction, mouth breathing
• How do you Dx a fb in nasal cavity?
- Typically based on visual inspection
* If unable to visualize may require fiber optic endoscopy
