Stomatitis • Viral • Herpangina • Hand foot and mouth • HSV
Pharyngitis • Superficial vs. deep • Sore throat, fever, HA, cough • Bacterial vs. Viral • EBV common presentation/ rash with abx
Bacterial Pharyngitis • GABHS usu. 5-15 yo accounts for 15-30% of pharyngits Tx. Amoxicillin 250mg BID or 500mg BID
Dental trauma • Most common in toddlers • Up to 75% of abused children have oral trauma • Subluxation: loosening • Luxation: displacement with ligament damage • Extrusion: displaced form socket
Dental trauma • Do not replace primary teeth • Do replace permanent teeth • 85-97% success rate if replaced in the first 5 min, near 0 if after 1 hour.
Mouth • Close internal lacerations with absorbable suture • “Baby bottle” 24-28% of children ages 2-5yrs • ANUG; teens to early 20’s, usu. Prevotella intermedia. Can lead toLudwigs angina. Tx. Pain control and oral abx. Rinse or oral abx. (pcn)
Neck masses • Cervical lympadenopahty • @ 55% of healthy children will have cervical nodes • <3mm are normal • < 1cm are normal in children >12 yrs The ex utero intrapartum therapy (EXIT)
lympadenitis • Most are reactive and require no tx. • Suppurative cases can be tx. Empirically, cover for staph and strep. • Amoxil or Augmentin 30-40mg/kg div BID • Clinda 30mg/kg div TID/BID for 10-14d

Specifics • Toxoplasmosis • T. gondii, protozoan in cat feces • Usu. Asymptomatic in healthy children • Up to 22.5 % U.S. infection rate.
Neck masses • Congenital • Thyroglossal duct cysts • Midline @ 70% of masses • Moves with swalloing • Branchial apparatus cysts • Anterior to SCM • Dermoid cyst/teratomas • Usu. Superhyoid/ can be mistaken for thyroglossal • Lymphatic malformations • Obstructed lymph flow, 75% in neck
Neck masses • Benign • Fibromatosis • Hemangioma • Neurofibroma • Goiter
Neck masses • Malignant • Lymphoma • 50% Hodgkins • Usu. Large firm anterior triangle or supraclavicular • Rhabdosarcoma • 2nd most common, orbit, middle ear or neck • Neuroblastoma • Arise from sympathetic chain • Rarely present as asymptomatic mass
Stridor and drooling • High pitched harsh sound produced by turbulent airflow. • 1mm of edema can reduce the cross-sectional area by 50% in children. • In the presence of stridor, suspect FB until proven otherwise.
<6mo • If long standing than probably congenital. • Laryngomalacia • Tracheomalacia • Vocal cord paralysis • Subglottic stenosis • Airway hemangiomas
>6 month • Croup • Most common cause of stridor outside neonatal period. • Most severe 3rd and 4th days • Clinical diagnosis • Treatment • Mild = steroids • Moderate = steroids +/- nebulized epi • Severe= steroids+epi • Pt’s with persistent stridor at rest or who require 2 epi tx should be admitted
Epiglottitis • Bacterial infxn of epiglottis. • Can result in life threatening swelling • Hib vaccine has greatly reduced incidence • Clinical features • Abrupt onset fever, drooling and sore throat • Treatment • Oxygen, raciemic, intubation as needed, ceftriaxone/vanc.
Foreign body • Most common in 1-3 year olds • Suspect in all young children with respiratory symptoms • Presentation may be delayed • >75% of foreign bodies can be seen on x-ray.
Retropharyngeal abscess • Usu due to fall with object in mouth • Slow onset due to bacterial overgrowth • Dx. When the retro space @ C2 is 2x the diameter of the vertebral body, or greater than ½ the width of C4.
Peritonsiller abscess • Same as adult
Bronchiolitis • Most common lower resp. infxn in <2yr • MCC RSV • Inflammation of LRT with edema • Peaks November-March • Last 7-14 days usu. Worse on day3-5
Dx/Tx • Dx • Clinical • RSV swab • Tx • Oxygen Sa02 >90 • Bi-level/ bi pap • Intubation • Hypertonic saline • Beta agonist/ steroids are controversial
Asthma • Inflammation • Bronchospasm • Airway obstruction
Presentation • More than 95% of children age 2-18 with asthma will present to the ED • Normal PaCO2 should be around 37 • PaCO2 40-42 may be sign of impending failure • Be aware of “silent chest” as an ominous sign
DX • Is there an asthma hx? • What is the severity of the airway obstruction? • Is there a reversible cause of the exacerbation?
CXR? • Rales or dullness that persists after SABA • Temp greater than 102.2 • Respiratory distress out of proportion for physical exam.
Treatment • Oxygen • SABA • Anticholinergics • Corticosteroids • Magnesium • Ketamine • Heliox • Methylxanthines
Near fatal asthma • 33% of fatalities occur in patients that previously had only mild asthma. • BiPap settings should begin at 12/6
