Given the importance of sexual health in intellectually disabled adolescents, the present study was conducted to explore the sexual health challenges in intellectually disabled adolescent girls.\u0000Materials and Methods: The present qualitative study with content analysis approach was conducted on 48 participants including parents, teachers, healthcare providers and managers who were selected through purposeful sampling method in Isfahan, Iran. Data were gathered using semi-structured in-depth interviews, focus group discussions and field notes. Data were analyzed using conventional content analysis.\u0000Results: After data analysis, four sub-categories of “adolescent’s disability in understanding sexual matters and respecting social rules”, “the coexistence of psychiatric disorders and intellectual disability”, cultural taboos on sexual issues” and “teachers’ inability to deal with issues related to adolescent’s sexual health” were extracted. These sub-categories together formed the main category of “sexual health challenges”.\u0000Conclusion: Based on the results, designing comprehensive programs of sex education for intellectually disabled adolescent girls seems necessary. Also, empowering teachers to teach sexual health to these girls and their parents is of particular importance. Furthermore, the interaction between parents and school to maintain the sexual health of intellectually disabled adolescent girls could have an effective role in decreasing the rate of sexual abuse/harassment and their involvement in sexual relationships.","PeriodicalId":51591,"journal":{"name":"International Journal of Pediatrics","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2021-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47160845","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 step one, the patients were initially examined by a pediatric cardiologist, and then in step two,; they were randomly divided into two groups (A and B) and were blindly re-examined by a 2nd-year pediatric resident. In Group A (Statoscope group), heart auscultation was performed using only a conventional Statoscope whereas, in Group B (Statoscope + DPM), heart sounds were detected and analyzed using a stethoscope and Doppler Phonolyser Machine. In the third step, the diagnostic results made by the pediatric cardiologist, the pediatric residents in groups A and B were compared with the final diagnostic echocardiography made by a pediatric cardiologist. \u0000Results: Heart murmurs as one of the most common reasons for cardiologist referrals consist of about 65% of referrals to pediatric cardiologists. There was only a moderate correlation between a Stethoscope stethoscope and echocardiography to identify cardiac abnormality based on heart murmurs (56%), whilste there was a significant correlation between the diagnoses made by Doppler Phonolyser accompanied with the conventional statoscope when compared with the echocardiography results. \u0000Conclusion: Doppler Phonolyser is an innovative smart machine that could efficiently detect and analyze abnormal heart sounds and might play a role in more accurate and earlier diagnosis of congenital and structural heart defects by general physicians and non-cardiologist specialists, and may potentially reduce the mortality, morbidity, and cost of treatment as well as anxiety of the patient's family.","PeriodicalId":51591,"journal":{"name":"International Journal of Pediatrics","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2021-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44790389","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}

Acute epiglottitis is relatively rare but can quickly lead to life-threatening airway obstruction. Diagnosis of epiglottitis is clinical, but radiography and direct vision of the epiglottis can also help with the diagnosis. Clinical manifestations of epiglottitis include fever, sore throat, and in the event of imminent airway obstruction, also may present with muffled sound, falls, tripod position, and stridor. Epiglottitis can be caused by some bacterial agents or viruses such as adenovirus and measles.COVID-19 was first detected in December 2019 in a group of patients with severe respiratory symptoms in Hubei Province, China. Common symptoms include fever, cough, fatigue, difficulty breathing, and loss of smell and taste. Although COVID-19 disease has a variety of manifestations, only one case of epiglottitis following COVID-19 disease has been reported in adults. \u0000\u0000Case presentation: The patient, a 4-year-old boy, came to our center and the patient's family complained of shortness of breath and progressive lethargy of the child 10 days ago.

On physical examination, respiratory distress, tachypnea, subcostal retraction, tail stridor, and crackle was heard in both lungs. Diagnosed with suspected bronchoscopy epiglottitis, a large, swollen, and cherry-red epiglottis was observed. Based on the patient's history of respiratory symptoms and the prevalence of COVID-19, a reverse pharyngeal polymerase (RT-PCR) transcript test was requested for COVID-19 and the COVID-19 infection was positive. \u0000\u0000Conclusion: In this article, we reported an 4-year-old child with epiglottitis in the context of COVID19.","PeriodicalId":51591,"journal":{"name":"International Journal of Pediatrics","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2021-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48923621","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}
