The age of cochlear implantation (CI) is often considered an important predictor of language skills of children with CI, but little is known about the benefits of early CI on speech intelligibility development in these children. This study aimed to compare language skills as well as intelligibility of speech in prelingual deaf patients who received CI before the age of six years and those who received CI after the age of six years with an 8-year follow-up.\u0000Materials and Methods: This 8-year longitudinal, retrospective case–control study was conducted in 2021 at a cochlear implant center in Tehran, Iran. Thirty-one patients were included in two groups: late cochlear implant (n = 15), and early cochlear implant (n =16). The Test of Language Development- Primary (TOLD-P3) was used to assess the participants 'language skills. The intelligibility of the participants' speech was assessed through the Persian version of the Intelligibility Context Scale (ICS) and the speech intelligibility rating (SIR).\u0000Results: These two groups did not show a significantly difference in terms of the language scores (P>0.05) but had a significantly difference in terms of the SIR and the ICS scores (P<0.05). Speech intelligibility had a significantly negative correlation with the age of CI (P<0.001), and had a significant positive correlation with language skills (P<0.001).\u0000Conclusion: The long-term outcomes of early and late CI were similar in terms of the development of language skills but too different in terms of the intelligibility of speech.

Materials and Methods: This cross sectional study was concocted on two groups of 8-12 years old children exposed (n=100) and non-exposed to passive smoking (n=100) in of Semnan (Iran). The sampling method was two-stage cluster sampling design. The data collection tool a standard checklist consisted of demographic, laboratory and dental characteristics. Examination was performed by a dentist on a dental unit and the dental indicators were measured for two groups. Also, salivary cotinine was measured and recorded using ELISA method by special cotinine kit (De salimetrics medi tec, USA). Univariate and Multivariable Logistic Regression model and area under the ROC curve were used to data analysis by STATA 14 software. Results: Univariate logistic regression model showed a statistically significant difference between the exposed and unexposed groups with passive smoking in term of the salivary cotinine level, age , sex , decayed, missing, and filled teeth (dmft) index, decayed, and filled teeth (dft) index and missing teeth (mt) (P-Value ≤0.20). However, multiple logistic regression model showed a statistically significant relationship between the decayed, missing, and filled teeth (dmft) index and passive smoking (OR=1.28; 95% CI: 1.05 – 1.38). Conclusion: This study showed that the risk of decay of deciduous teeth is higher in children exposed to passive smoking, therefore, passive smoking should be considered in the implementation of programs to prevent tooth decay in children.","PeriodicalId":51591,"journal":{"name":"International Journal of Pediatrics","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2021-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42407460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the view of controversies in current clinical studies for efficiency of CGA in CS patients, we performed a systematic review of the literature to clarify the debate. Methods: A comprehensive literature search was performed to identify studies assessing CGA outcome in CS patients, in following databases and search engines: Ovid MEDLINE, PubMed, Scopus, Cochrane Central Register of Controlled Trials (CCTR), EMBASE, Google Scholar, and Web of Science. Two authors screened the search results and selected the studies by the supervision of senior authors.Results: In 19 studies, enrolling 363 patients, age at surgery was 58.76 months ranging from 4 to 216 months. Anterior and posterior hemiepiphysiodesis was the most common approach. Eight studies added instrumentation to CGA. Follow-up mean was 64.57 months. Nine studies reported true epiphysiodesis effect (postoperative and final follow-up CCA difference): of 162 patients, 69 improved, 59 stabilized, and 34 progressed. Other studies reported preoperative and final follow-up CCA difference: of 88 patients, 49 improved, 32 stabilized, and 7 progressed. Preoperative curve magnitude, sagittal plane deformities, age <5 years, and type of spinal anomalies did not affect CGA outcome.
