Results: In the present study, criteria of clinical practice regarding the stages of newborn screening by pulse oximetry at birth were determined based on the evidence and health conditions and were presented in twenty-eight recommendations and six sections. The final recommendations were presented in the results section.
Conclusion: The finding of the present study showed that physicians, nurses, and midwives can apply the recommendations of this clinical guideline for the early detection and referral of neonates with critical congenital heart disease. |
Methods: In this cross-sectional study (descriptive analytic), the records of 2739 neonates who had been recalled during the CH screening program in the east of Tehran, Iran (health care centers of the Iran University of Medical Sciences), from March 2011 to March 2015, were studied. According to the CH screening program in Iran, the TSH on filter paper>5 is the current cut-off point for recalling the neonates. The data was analyzed with SPSS software, version 21. The ROC curve was used to determine the TSH cut-off point and the sensitivity and specificity of the filter test. The relationship between the filter and serum TSH was also determined. The study was approved by the Ethics Committee of the Iran University of Medical Sciences.
Results: The recall rate was 5.4%. The prevalence of hypothyroidism was 3/1000 neonates (164). The prevalence in males and females was 51.1% and 48.9%, respectively, with no significant difference. The number of recalled neonates diagnosed as patients with congenital hypothyroidism based on the filter TSH level was 5 Conclusion: Based on the findings of the study, considering the kits available in the country and their sensitivity and specificity, the importance of diagnosing infants with congenital hypothyroidism, and the lower cost of filter paper than missing a hypothyroid infant, the current cut-off point is acceptable. However, more studies are needed in different regions of Iran to obtain more accurate results. |
Results: Congenital cytomegalovirus infection was diagnosed in 8 of 63 newborns (12.7%). Hearing loss was seen in 2 infected infants. The mean of head circumferences among infected neonates was significantly lower than that observed in uninfected cases. Infants with CMV related symptoms had statistically more chance to have infection (P=0.02). We also found Guthrie cards as a reliable sample with high sensitivity for CMV detection assays.
Conclusion: The current study showed a high rate of symptomatic congenital CMV infection among neonates attending on NICU sections of hospitals in Tehran, Iran. It is of crucial importance to note that based on evidence, diagnosis of infants with congenital CMV infection at early stages could help to decrease the burden of long-term diseases if associated with prompt interventions and reduce the costs of late-ineffective treatment. Therefore, routine screening of newborns for congenital CMV infection via Guthrie cards is suggested. |
