    OBJECTIVES: The aim of this case-control study was to evaluate the nasopharyngeal pH (NasopH) in children with normal or abnormal pH-metry in two groups of patients: 1) children presenting gastroenterological symptoms; and 2) children with chronic respiratory symptoms. METHODS: From February 2004 to January 2005, all consecutive patients referred for 24-hour pH-metry and in whom gastroesophageal reflux disease was suspected were enrolled in a prospective study. They were assigned to four groups: gastroenterological symptoms with normal (A) or abnormal (B) pH-metries (GG), and chronic respiratory symptoms with normal (C) or abnormal (D) pH-metries (RG). NasopH was measured for 5 minutes, before the 24-hour test was performed. RESULTS: Thirty-eight pH-metry tests were included (20 in the RG and 18 in the GG). Abnormal pH-metry results were observed in 11 patients in the GG and in 12 in the RG. NasopH means were 6.3273 and 5.6917, respectively (p < 0.0001). Average nasopharyngeal pH was 5.6917 among the 12 RG patients with abnormal pH-metry results and 6.5000 among the remaining eight patients with normal test results (p = 0.0006). Analysis of the RG with a receiver operating characteristic (ROC) curve showed pH of 5.8 as cutoff point (sensitivity of 91.7% and specificity of 87.5%). The area below the ROC curve was 0.870. CONCLUSIONS: Nasopharyngeal pH is significantly lower among patients in the RG presenting abnormal pH-metry results. A 5.8 NasopH has good sensitivity and specificity and can be used as a screening test in patients with chronic respiratory diseases to select those for whom conventional 24-hour pH-metry is indicated.

    The role of radiographic measurements in the evaluation of congenital clubfoot surgical results
    (Springer, 2007-02-01) Fridman, Marcos William; Sodre, Henrique [UNIFESP]; Sao Lucas Hosp; Universidade Federal de São Paulo (UNIFESP)
    A series of 50 patients with 71 clubfeet treated surgically was evaluated after exclusion of individuals with associated malformations, syndromes, neurological disorders, previous surgery and age over 30 months at the time of the surgical procedure. They underwent soft-tissue releases that addressed all the components of the deformity, including, when necessary, the calcaneocuboid joint. the age of the patients at the time of the surgery ranged from 6 to 26 months and the mean follow-up period was 77.03 months. the scores resulting from the application of the functional rating system designed by Laaveg and Ponseti were compared with several radiological parameters described in the medical literature to verify the degree of statistical association between these variables. the talo-first metatarsal angle, the calcaneal-second and fifth metatarsal angles were the only radiological measurements that correlated well with the functional score.
