Development and Modification of an Outcome Measure to Follow Symptoms of Children with Sinusitis.

Objective: To develop a parent-reported Pediatric Rhinosinusitis Symptom Scale (PRSS) that could be used to monitor symptoms of young children with acute sinusitis in response to therapy.

Study Design: We developed an 8-item symptom severity scale and evaluated its internal reliability, construct validity, and responsiveness in children 2-12 years of age with acute sinusitis. Parents of 258 children with acute sinusitis completed the PRSS at the time of diagnosis, as a diary at home, and at the follow-up visit at days 10-12.

Predicting response to antimicrobial therapy in children with acute sinusitis.

Objective: To determine prognostic factors that independently predict response to antimicrobial therapy in children with acute sinusitis.

Study Design: A total of 206 children meeting a priori clinical criteria for acute sinusitis who were prescribed antimicrobial therapy by their primary care provider were included. The severity of symptoms in the 8-12 days after treatment was initiated was followed with the use of a validated scale.

Are nasopharyngeal cultures useful in diagnosis of acute bacterial sinusitis in children?

The diagnosis of acute bacterial sinusitis can be challenging because symptoms of acute sinusitis and an upper respiratory tract infection (URI) overlap. A rapid test, if accurate in differentiating sinusitis from URI, could be helpful in the diagnostic process. We examined the utility of nasopharyngeal cultures in identifying the subgroup of children with a clinical diagnosis of acute sinusitis who are least likely to benefit from antimicrobial therapy (those with completely normal sinus radiographs).

Signs and symptoms that differentiate acute sinusitis from viral upper respiratory tract infection.

Objective: Differentiating acute bacterial sinusitis from viral upper respiratory tract infection (URI) is challenging; 20% to 40% of children diagnosed with acute sinusitis based on clinical criteria likely have an uncomplicated URI. The objective of this study was to determine which signs and symptoms could be used to identify the subgroup of children who meet current clinical criteria for sinusitis but who nevertheless have a viral URI.

Methods: We obtained sinus radiographs in consecutive children meeting a priori clinical criteria for acute sinusitis.

Orbicularis oris muscle defects as an expanded phenotypic feature in nonsyndromic cleft lip with or without cleft palate.

Nonsyndromic cleft lip+/-cleft palate is a complex disease with a wide phenotypic spectrum; occult defects of the superior orbicularis oris muscle may represent the mildest subclinical form of the lip portion of the phenotype. This study used high-resolution ultrasonography to compare the frequency of discontinuities in the OO muscle in 525 unaffected relatives of individuals with nonsyndromic cleft lip+/-cleft palate versus 257 unaffected controls. OO muscle discontinuities were observed in 54 (10.

A pilot study of heel ultrasound to screen for low bone mass in children with leukemia.

The optimal method to assess pediatric bone mass remains controversial. Dual x-ray absorptiometry (DXA) is commonly used but quantitative ultrasound is less expensive, free of ionizing radiation, and predicts fractures as well as DXA does, in adults. Broadband ultrasound attenuation (BUA) was determined using a portable calcaneal ultrasonometer and, compared with DXA derived areal bone mineral density (BMD) values in 42 young patients (ages 4.

Altered bone mass in children at diagnosis of Crohn disease: a pilot study.

Objectives: Recent studies have indicated that bone mineral density is reduced in children with inflammatory bowel disease. The exact cause of this reduction is unclear, but it is often attributed to corticosteroid use. This study examined the prevalence of reduced bone mass in otherwise healthy children newly diagnosed with Crohn disease without previous corticosteroid exposure.

Hemodynamic disturbances in premature infants born after chorioamnionitis: association with cord blood cytokine concentrations.

Chorioamnionitis and elevated cord blood inflammatory cytokine concentrations are associated with detectable disturbances of systemic and cerebral hemodynamics in premature newborns. Fifty-five infants (25-31 wk gestation) were enrolled. Chorioamnionitis was defined by placental histology.

Ultrasound diagnosis of craniosynostosis.

Objective: To retrospectively study prenatal ultrasound images of patients with craniosynostosis to determine the extent to which prenatal diagnosis is possible.

Method: Prenatal ultrasound images of 19 patients with postnatally diagnosed metopic or coronal suture craniosynostosis were retrospectively reviewed. The 26 ultrasound examinations obtained were compared with normal images and tables of gestation.
