The speech and language status of 662 children between the ages of 30 months and 5 years was determined through the use of parent report information. Twelve of these children were reported by their parents to have been diagnosed as having a speech-language disorder, and 50 of these children were found to be at or below the 10th percentile in language development for children of their age. Information about family background and birth history obtained when these children were born was evaluated with respect to its power to predict speech-language status in these preschool children. A set of risk criteria was found to accurately predict 55% of those children with poor communication skills and 76% of those with normal communication development. This prediction was improved by the addition of data about the child’s birth order. These results suggest that programs of preschool identification should consider the inclusion of a registry of children who are at risk for a communication disorder.
Peak intraoral air pressures were recorded during speech acts of ten children and ten adults by use of a polyethylene tube positioned in the oral-pharyngeal cavity. These pressures were measured during selected consonants spoken under a variety of conditions. Air pressures for voiceless consonants were found to be significantly higher than for voiced consonants, and higher peak intraoral air pressures were associated with stop consonants than with continuant consonants. For adults, successively higher magnitudes of peak intraoral air pressures were found at progressively higher levels of speech intensity. For the children, higher pressures were associated with consonants in the intervocalic context than in pre- and postvocalic contexts.
Summary
Equine axillary wounds are common in horses. Severe and potentially life‐threatening complications that can result from axillary wounds include subcutaneous emphysema, pneumomediastinum and pneumothorax. This report describes the occurrence of these complications and appropriate treatment. Case records of 7 horses after sustaining an axillary wound are reviewed. Of these cases, all 7 developed subcutaneous emphysema, 5 developed a pneumomediastinum and 4 developed a pneumothorax. The time between the wound occurrence and the development of subcutaneous emphysema was able to be determined in 5 of the 7 cases. The mean ± s.d. time for the development of subcutaneous emphysema following initial injury was 3.2 ± 0.84 days (range 2–4 days). Resolution of subcutaneous emphysema was not achieved until the treatment included packing the wound to stop it from acting as a one‐way valve. Horses with a pneumothorax in respiratory distress were managed with thoracocentesis or placement of thoracic drains. Horses with a pneumothorax but without respiratory distress were treated with conservative management. All horses survived to discharge.
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.
