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.

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.

Acute epiglottitis is relatively rare but can quickly lead to life-threatening airway obstruction.
