Communication in Daily Life of Children With Developmental Language Disorder: Parents' and Teachers' Perspectives.

Purpose: This study explores limitations in communication in daily life of children with developmental language disorder (DLD) from their parents' perspective as well as communicative abilities and social functioning in the classroom from their teacher's perspective. Furthermore, differences between children with mixed receptive-expressive disorder and children with expressive-only disorder in communication in daily life and social functioning are studied.

Method: Data were collected through questionnaires completed by parents and teachers of children (5-6 years old) who attended schools for special education for DLD.

Language gains in 4-6-year-old children with developmental language disorder and the relation with language profile, severity, multilingualism and non-verbal cognition.

Background: Early and effective treatment for children with developmental language disorder (DLD) is important. Although a growing body of research shows the effects of interventions at the group level, clinicians observe large individual differences in language growth, and differences in outcomes across language domains. A systematic understanding of how child characteristics contribute to changes in language skills is still lacking.

Focused Stimulation Intervention in 4- and 5-Year-Old Children With Developmental Language Disorder: Exploring Implementation in Clinical Practice.

Purpose Applying evidence-based grammar intervention can be challenging for speech and language therapists (SLTs). Language in Interaction Therapy (LIT) is a focused stimulation intervention for children with weak morphosyntactic skills, which was developed to support SLTs in incorporating results from effect studies in daily practice. The aims of this Clinical Focus are (a) to explain the principles and elements of LIT and stimulate use in daily SLT practice and (b) to describe the effects of LIT on morphosyntactic skills of 4- to 5-year-olds in special education, compared to usual care.

Influence of day and night wear on surface properties of silicone hydrogel contact lenses and bacterial adhesion.

Purpose: The aim of this study was to determine the effect of continuous wear on physicochemical surface properties of silicone hydrogel (S-H) lenses and their susceptibility to bacterial adhesion.

Methods: In this study, volunteers wore 2 pairs of either "lotrafilcon A" or "balafilcon A" S-H contact lenses. The first pair was worn continuously for a week and the second pair for 4 weeks.

Resistance to a polyquaternium-1 lens care solution and isoelectric points of Pseudomonas aeruginosa strains.

Objectives: The aim of this study was to correlate the cell surface hydrophobicity and charge of various strains of Pseudomonas aeruginosa with their resistance to a polyquaternium-1 lens care solution.

Methods: The 11 P. aeruginosa strains included were isolated from eyes, contact lenses, lens cases and lens care solutions.

Hydrophobicity of peritoneal tissues in the rat.

In this study, an inventory of the hydrophobicity of peritoneal tissues in the living rat was made. Peritoneal tissues were divided into mesentery (i.e.

Bacterial transmission from contact lenses to porcine corneas: an ex vivo study.

Purpose: To quantify the transmission to ex vivo porcine eyes of Staphylococcus aureus 835 and Pseudomonas aeruginosa 3 from three types of contact lenses-one daily wear and two extended wear-differing in hydrophobicity and roughness.

Methods: One daily wear lens (etafilcon) and two extended-wear lenses (one lotrafilcon A and one balafilcon A) were inoculated in a bacterial suspension for 30 minutes and then placed on ex vivo porcine eyes. After 16 hours of contact between lens and eye, confocal laser scanning microscopy was used to determine the number of bacteria on the lens and cornea for the calculation of transmission percentages.

Physicochemical factors influencing bacterial transfer from contact lenses to surfaces with different roughness and wettability.

The aim of this study was to determine the transfer of Pseudomonas aeruginosa No. 3 and Staphylococcus aureus 835 from contact lenses to surfaces with different hydrophobicity and roughness. Bacteria were allowed to adhere to contact lenses (Surevue, PureVision, or Focus Night & Day) by incubating the lenses in a bacterial suspension for 30 min.

Influence of wear and overwear on surface properties of etafilcon A contact lenses and adhesion of Pseudomonas aeruginosa.

Purpose: To determine changes in physicochemical surface properties of contact lenses (CLs) during daily wear and effects of lens wear on adhesion of a Pseudomonas aeruginosa strain from a patient with CL-related keratitis.

Methods: Ten new CL wearers used ionic, etafilcon A lenses with 58% water on both eyes for approximately 10 hours each day during 10 and 50 days. All lenses were treated daily with an appropriate lens care solution.
