Evolution of guidelines for pediatric rhinosinusitis

Fifty Years of Chronic Rhinosinusitis in Children: The Accepted, the Unknown, and Thoughts for the Future

Chronic sinusitis is an often-used term in both lay and medical circumstances. In children, it has significant but largely undefined healthcare costs. Chronic rhinosinusitis (CRS) in children has well demarcated time periods and symptoms, although the actual pathway from normal sinus to CRS is not well understood. There is reasonable consensus as to the standards for diagnosis, the selection of a first-round antibiotic, and length of treatment. However, no recent prospective studies of antibiotics are available. Areas of continued speculation include the following: the microbiome of pediatric CRS, the best use of standard imaging, alternative antibiotic selection, ancillary therapy, and treatment of refractory CRS. In addition, older adolescents can present with a more adult-oriented CRS with or without polyps, suggesting a broader spectrum of disease than is commonly recognized. An accounting of the accepted elements of pediatric rhinosinusitis, as well as areas for future research, is emphasized in this review and, where appropriate, suggestions for potential investigations are offered.

May chronic rhinosinusitis in children be diagnosed by clinical symptoms?

OBJECTIVES

Chronic rhinosinusitis (CRS) is a common disease in childhood but is often underdiagnosed because the symptoms are subtle and similar to other nasal pathologies. No clinical symptom is pathognomonic, and consensus documents suggest nasal fibroendoscopy (NF) or imaging criteria (computed tomography, magnetic resonance imaging) as the gold standards for diagnosis of CRS. However, considering the frequent unavailability of such tools to physicians, we designed this study to evaluate whether combinations of symptoms may achieve a clinical diagnosis of CRS in children as confirmed by NF.

METHODS

The study population consisted of 275 children with a clinical diagnosis of CRS, in 228 of whom diagnosis of CRS was confirmed by NF, while in 47 diagnosis was not confirmed by NF and they served as the control group. The symptoms considered were nasal obstruction, nasal discharge, cough, facial pain, and halitosis, using for statistical analysis multivariate logistic regression, Wald tests, and receiver operating characteristic (ROC) curve.

RESULTS

The multivariate logistic regression for CRS symptoms indicated rhinorrea as the strongest predictor of CRS. With three symptoms the probability of CRS was from 60% to 75% without rhinorrea and 77-91% in the presence of this symptom, with four symptoms the probability was over 93%, and with all the five symptoms the probability of having CRS was virtually 100%.

CONCLUSIONS

These findings suggest that an initial symptoms assessment may help to recognize children with a high probability of CRS, thus reducing the need of NF or imaging techniques.
