Aim:To assess the incidence of different head and neck cancers in pediatric age group in a referral hospital.Methods:In this prospective study, children below the age of 12 years underwent a thorough clinical, ENT examination and the diagnosis was conformed histologically in all the cases.Results:Fifty-three were diagnosed to be suffering from different head and neck neoplasms among 21,216 children (0.25%). Male-to-female sex distribution was 1.78:1. The lymphomas were the most common (43.39%) followed by the rhabdomyosarcoma (20.75%) and the nasopharyngeal carcinoma (15.09%). Of the lymphomas, the non-Hodgkin's lymphoma was predominant (26.41%). Other lesions were thyroid carcinomas and mucoepidermoid carcinoma of parotid.Conclusions:Malignancy should always be considered in the differential diagnosis of masses in the head and neck region in children.
Our aim was to find out the association between nasal smear eosinophil count and allergic rhinitis (AR) and to determine a cutoff value that is significant for a diagnosis of AR. We also wanted to determine whether this count is related to the predominant symptoms, duration, or type and severity of AR, or to the presence of coexisting asthma. We selected 100 patients with a clinical diagnosis of allergic rhinitis across all age groups and an equal number of age-and sex-matched controls for the study. Their nasal smear eosinophil counts were recorded in terms of the number of eosinophils per high-power field (HPF). All patients were then clinically assessed for asthma and underwent spirometry. The data were recorded and appropriate statistical analysis done. The difference in the mean eosinophil counts of patients with AR and controls was found to be statistically significant (p = 0.000). A nasal smear eosinophil count of >0.3 per HPF had a 100% specificity and a 100% positive predictive value for AR. Asthma was associated with allergic rhinitis in 40% of patients; an association was not found between nasal smear eosinophil count and the symptoms, duration, type, and severity of allergic rhinitis or coexistent asthma. We conclude that an eosinophil count of >0.3 per HPF in nasal smears is a highly specific criterion for the diagnosis of AR. However, nasal smear eosinophil counts are poor indicators of the degree, duration, or type of upper or associated lower airway inflammation due to allergy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
