In the present study, screening results at 1 month of age resembled the final diagnosis obtained at 6 months of age; out of 31 REFER cases, 26 cases were diagnosed with hearing loss. In contrast, in the multiple institutional study, both unilateral and bilateral REFER rates were much higher than the rates of final hearing loss. Concerning the final diagnoses of bilateral hearing loss, the authors' results (0.10%) and the multiple institutional studies' results (0.05% in low-risk and 2.19% in high-risk neonates) were comparable to the results reported in the USA. To expand the newborn hearing screening program, it is crucial that authority and institutions concerned promote the development of a national or prefecture-based early hearing loss identification and intervention network.
Objective: To investigate the effect of urinary trypsin inhibitor (UTI) in patients at risk for premature labor with bulging membrane. Methods: Patients who had developed a bulging membrane from 22 to 27 weeks and 6 days of gestation were studied. These cases were divided into two types based on the severity: those with a moderately developed bulging membrane like a ‘dome’ (dome type), and those with a membrane prolapsed into the vagina, resulting in an ‘hourglass’ shape (hourglass type). We compared the outcomes of treatment with or without UTI (UTI group versus non-UTI group) in each type. Gestational age at delivery, birth weight, prolongation time from admission to delivery, and neonatal mortality rate were examined in each group. Results: A total of 43 patients with a bulging membrane were analyzed. In 21 patients with the dome type, gestational age at delivery (the UTI group versus the non-UTI group; 30.4 ± 5.0 versus 26.4 ± 1.9 weeks, p < 0.05), birth weight (1,436.8 ± 708.3 versus 882.8 ± 261.6 g, p < 0.05) and neonatal mortality rate (0/13 versus 3/8, p < 0.05) were all significantly improved by the use of UTI. On the other hand, in 22 patients with the hourglass type, there was no significant difference between the UTI group and the non-UTI group. The overall prevalence of histological chorioamnionitis was 60%. Conclusion: These results suggest that UTI therapy is very effective in patients at risk for premature labor with a moderately developed bulging membrane during the second trimester.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
