OBJECTIVE Investigate the prevalence of hearing impairment in newborns hospitalized at the Intensive and Intermediate Care Unit at the Women's Comprehensive Health Center Neonatology Service (UNICAMP) and associated risk factors. METHODS 979 newborn babies were assessed between January 2000 and January 2003, through automated auditory brainstem response (AABR) (ALGO 2e color screener). The re...

Concrete is responsible for a significant share of global GHG emissions, which can be mainly ascribed to the production clinker. Alkali-activated concretes have been investigated in literature as possible alternative, but sustainability still appears reduced by high embodied energy chemicals typically used activation step. This paper investigates concrete belonging strength classes 35, 50 and 7...

INTRODUCTION This study aims to review the results of hearing screens in newborns with cleft deformities. MATERIALS AND METHODS A retrospective audit of 123 newborns with cleft deformities, born between 1 April 2002 and 1 December 2008, was conducted. Data on the results of universal newborn hearing screens (UNHS) and high-risk hearing screens, age at diagnosis, severity/type of hearing loss ...

The feasibility of universal newborn hearing screening (UNHS) using automated auditory brainstem response (AABR) devices in the neonatal intensive care unit (NICU) is already well demonstrated. The aim of this study was to find out whether the postconceptional age (PCA) of the babies at the time of the AABR measurement has an influence on the measuring results and to determine the earliest time...

Purpose: To compare the testing time of two Automated Auditory Brainstem Response (AABR) procedures using different repetition rates and detection modes. Methods: A hearing screening using AABR was performed in 30 newborns with mean age of 21 days. Each newborn was submitted to two hearing screening procedures using different AABR equipments (Procedure 1 and Procedure 2). Procedure 1 used a rep...

OBJECTIVE The objective of this study was to evaluate the accuracy and cost effectiveness of three different methods of hearing screening in newborns. DESIGN A prospective, randomized cohort design was used. One hundred and five newborns were tested in this preliminary study. SETTING The study was conducted in a tertiary care hospital setting in both the well baby and special care nurseries...

BACKGROUND In 2009, the Chinese Ministry of Health recommended scale-up of routine neonatal hearing screening - previously performed primarily only in select urban hospitals - throughout the entire country. METHODS A decision analytical model for a simulated population of all live births in china was developed to compare the costs and health effects of five mutually exclusive interventions: 1...

Congenital Permanent Childhood Hearing Impairment (PCHI) is known to have a negative effect on language acquisition, cognitive development and social integration. Since 2000 our department has implemented a UNHS program in the West of Ireland. We describe our experience and detail our results to date. All neonates born from October 2000 to November 2007 were screened using a 2-stage protocol. T...

BACKGROUND To screen the newborn by Transient evoked Otoacoustic emission and to assess the incidence of hearing damage and associated risk factors. METHOD This longitudinal prospective observational study was conducted at a tertiary care hospital in India. A total of 415 babies were included in the study. All the newborns were evaluated with Transient evoked Otoacoustic emission (TEOAE) whic...
