Development and Evaluation of the Italian Version of the Dichotic Digit Test: Insights from 39 Normal-Hearing Children Aged 11 to 13 years.

BACKGROUND The dichotic digit test (DDT) is one of the tests for the behavioral assessment of central auditory processing. Dichotic listening tests are sensitive ways of assessing cortical structures, the corpus callossum, and binaural integration mechanisms, showing strong correlations with learning difficulties. The DDT is presently available in a number of languages, each appropriate for the subject's native language.

AudBility: an online program for central auditory processing screening in school-aged children from 6 to 8 years old.

Purpose: To analyze the performance of students aged between in an auditory skills screening software program, considering the influence of biological determinants and the correlation of auditory tasks with the behavioral assessment tests of central auditory processing (PAC), as well as to present the cutoff points of the battery.

Methods: In the first stage, the sample consisted of 96 students with typical development, who underwent hearing screening at school. A self-perception questionnaire and the auditory tasks of sound localization (SL), temporal resolution (TR), temporal ordering of frequency (OT-F) and duration (OT-D), auditory closure (AC), dichotic digit- binaural integration (DD) and figure-ground (FG) were applied.

AudBility: test-retest reliability in typically developing children aged 6 to 7 years.

Purpose: to investigate the test-retest reliability of the AudBility program in typically developing children aged six-seven years.

Methods: 29 children, male and female, right-handed, native Portuguese speakers and adequate school performance for the age group studied, underwent previous meatoscopy, immittance measurements and the AudBility program was applied, composed of a self-perception questionnaire and auditory tasks, being analyzed the abilities of sound localization, auditory closure, figure-ground, dichotic digits test, temporal resolution, and temporal ordering of frequency and duration. The program was designed and reapplied with an interval of one week under the same conditions.

AudBility: Effectiveness of an online central auditory processing screening program.

Objective: To contribute to the validation of AudBility, an online central auditory processing screening program, considering the tasks for age between 6 and 8 years-old, from the investigation of sensitivity and specificity, as well as to suggest a minimum central auditory processing (CAP) screening protocol in this age group.

Method: In the first stage of the study, 154 schoolchildren were screened. Children were aged between 6 and 8 years old, native speakers of Brazilian Portuguese.

Masking Level Difference: Performance of School Children Aged 7-12 Years.

Background And Objectives: In masking level difference (MLD), the masked detection threshold for a signal is determined as a function of the relative interaural differences between the signal and the masker. Study 1 analyzed the results of school-aged children with good school performance in the MLD test, and study 2 compared their results with those of a group of children with poor academic performance.

Subjects And Methods: Study 1 was conducted with 47 school-aged children with good academic performance (GI) and study 2 was carried out with 32 school-aged children with poor academic performance (GII).

Orofacial Trauma on the Anterior Zone of a Trumpet's Player Maxilla: Concept of the Oral Rehabilitation-A Case Report.

Background: The occurrence of an orofacial trauma can originate health, social, economic and professional problems. A 13-year boy suffered the avulsion of tooth 11 and 21, lost at the scenario.

Methods: Three intraoral appliances were manufactured: A Hawley appliance with a central expansion screw and two central incisors (1), trumpet edentulous anterior tooth appliance (2) and a customized splint (3) were designed as part of the rehabilitation procedure.

Computer-based central auditory processing screening for school-age children (audBility): an initial investigation.

Purpose: To study an initial version of a new computer-based program for auditory processing screening of school-age children: "audBility." Specifically, the study aimed to analyze performance in individual tasks, level of difficulty per age group, administration time and data management and propose adjustments for a final version to be validated in future research, based on the administration of "audBility" on children with good school performance.

Methods: Forty-three school-age children with good school performance were selected.

Procedures for central auditory processing screening in schoolchildren.

Introduction: Central auditory processing screening in schoolchildren has led to debates in literature, both regarding the protocol to be used and the importance of actions aimed at prevention and promotion of auditory health. Defining effective screening procedures for central auditory processing is a challenge in Audiology.

Objective: This study aimed to analyze the scientific research on central auditory processing screening and discuss the effectiveness of the procedures utilized.

Evaluation of speech in noise abilities in school children.

This study aimed to analyze the perception of speech in noise in children with poor school performance and to compare them with children with good school performance, considering gender, age and ear side as variables. The intelligibility of speech was evaluated in school children utilizing the Brazilian Hearing in Noise Test (HINT) in the situations of quiet (Q), Left ear competitive noise (NL), Right Ear Competitive Noise (NR), as well as the global average of other hearing situations, denominated Noise Composite (NC). Ninety seven school children between the ages of 8 and 10 were recruited in five schools of São Paulo-Brazil; the control group (CG) consisted of 54 students (23 male/ 31 female) without language and/or speech difficulties and good school performance, and the study group (SG) consisted of 43 students (28 male/ 15 female) identified by their teachers as having poor school performance.

Hearing in Noise Test, HINT-Brazil, in normal-hearing children.

Introduction: The auditory processing is related to certain skills such as speech recognition in noise. The HINT-Brazil test allows the measurement of the Speech/Noise ratio however there are no studies in the national literature that establish parameters for the child population.

Objective: To analyze the performance of normal-hearing subjects aged 8-10 years old in tasks for speech recognition in noise using HINT test.

[Collection of tracheal aspirate: safety and microbiological concordance between two techniques].

Objective: To evaluate the safety of the performance of the traditional and protected collection techniques of tracheal aspirate and to identify qualitative and quantitative agreement of the results of microbiological cultures between the techniques.

Method: Clinical, prospective, comparative, single-blind research. The sample was composed of 54 patients of >18 years of age, undergoing invasive mechanical ventilation for a period of ≥ 48 hours and with suspected Ventilator Associated Pneumonia.

Metallo-β-lactamase and genetic diversity of Pseudomonas aeruginosa in intensive care units in Campo Grande, MS, Brazil.

Infection by Pseudomonas aeruginosa has spread worldwide, with limited options for treatment. The purpose of this study was to investigate metallo-β-lactamase-producing P. aeruginosa strains and compare their genetic profile using samples collected from patients in intensive care units.

Activities of 2,4-dihydroxy-6-n-pentylbenzoic acid derivatives.

Esters of 2-hydroxy-4-methoxy-6-n-pentylbenzoic acid (2-8) (methyl, ethyl, butyl, pentyl, isopropyl, sec-butyl and benzyl), olivetol (9), methyl, ethyl, butyl perlatolates (10-12), 2,4-dihydroxy-6-n-pentylbenzoic acid (15), and methyl and ethyl esters of (15) were prepared through structural modifications of perlatolic acid (1) with the aim to detect new antifungal and antibacterial substances and also to evaluate the toxicity by the brine shrimp lethality assay against Artemia salina. The antifungal assays were carried out against the fungus Cladosporium sphaerospermum through the bioautography method, and methyl 2,4-dihydroxy-6-n-pentylbenzoate (13) showed the highest antifungal activity (2.5 yg).
