Pharyngeal fibrovascular polyp in a child.

Fibrovascular polyp of the upper aerodigestive tract is an uncommon tumor that may present in pediatric patients with symptoms ranging from dysphagia to asphyxiation and death. We present a unique case of a pediatric patient with an asymptomatic fibrovascular polyp noted as an incidental finding on a cervical ultrasound evaluation. This lesion extended from the posterior tonsillar pillar and prolapsed freely into the nasopharynx and esophagus.

Globoid cell leukodystrophy: comparison of neuropathology with magnetic resonance imaging.

Previous imaging studies in infants with globoid cell leukodystrophy (GLD) using computed tomography have demonstrated a reduction in cerebral white matter and increased density symmetrically in the regions of the thalami, periventricular white matter, and the internal capsules. Correlation of these findings with morphologic studies at necropsy has not been made. In particular, deposition of calcium has not been described.

Radiographic changes associated with tracheal isolation of Ureaplasma urealyticum from neonates.

Recent studies show an association between the presence of Ureaplasma urealyticum in tracheal aspirates and bronchopulmonary dysplasia. We hypothesized that among infants with birth weights < or = 1,250 g and respiratory disease, those with U. urealyticum in their tracheal aspirates would have radiographic evidence of more-severe pulmonary disease more often than would those without this organism.

Subacute sinusitis: are antimicrobials necessary?

Background: The need for antimicrobials in the treatment of subacute sinusitis was evaluated in 96 afebrile children who were prescribed antimicrobial (amoxicillin, amoxicillin clavulanate potassium, or trimethoprim-sulfamethoxazole) or no antimicrobial medication in addition to a decongestant and saline nasal spray for 3 weeks.

Methods: Response was determined by complete clearing of the initial radiologic abnormalities or in the case of mucosal thickening, by a significant decrease in thickness to < 6 mm within the maxillary sinuses associated with improvement of the clinical signs and symptoms of sinusitis. If there was evidence of partial clearing by radiograph, the same therapy was continued for another 3 weeks.
