Does classroom amplification aid comprehension?

Many classrooms are noisy and this interferes with listening and teaching. FM soundfield (FM) amplification systems have been developed which provide a uniform soundfield throughout the classroom and increase the speech-signal:noise ratio. The effect on comprehension of such a system was investigated. Forty-nine pupils (comprising the two top classes of a mainstream primary school) participated in this study, with a mean age of 9.92 years (range 8.58-11.42 years). The Neale Analysis of Reading Ability (Neale, 1988a, b) was modified and administered as a spoken comprehension test. Tests of nonverbal intelligence, auditory memory and a questionnaire were given. The passages spoken though the FM amplification system were understood better than the comparable unamplified passages. Auditory memory, sex and non-verbal intelligence had no effect on improved comprehension. FM amplification significantly improved comprehension and could be considered for use in other schools.

Autosomal dominant "Opitz" GBBB syndrome due to a 22q11.2 deletion.

We report on a family with autosomal dominant paternally inherited "Opitz" GBBB syndrome and an additional case with findings which have been reported in that syndrome. In each case the propositus presented with a vascular ring. Since a vascular ring may be a sign of a 22q11.2 deletion [Zacki et al., 1995], FISH (fluorescence in situ hybridization) studies were performed. These studies demonstrated a 22q11.2 deletion in the 3 affected individuals. Review of Opitz GBBB syndrome and the 22q11.2 microdeletion syndrome demonstrates significant overlap of manifestations including both facial characteristics and structural anomalies. Based on the phenotypic overlap and the presence of a 22q11.2 deletion in our patients with Opitz GBBB syndrome and the presence of a deletion in a patient with lung hypoplasia, absent pulmonary artery, and long segment tracheomalacia, we propose that, in some cases, the Opitz GBBB syndrome may be due to a 22q11.2 deletion. This enlarges the list of "syndromes" associated with the 22q11.2 deletion, which presently includes most patients with DiGeorge, velocardiofacial, and conotruncal anomaly face syndrome.

Parents' attitudes and patients' behavior: a prospective study.

The authors studied the behavior of 67 psychiatric inpatients and the attitudes of their parents toward their hospitalization. They found that certain parental concerns at admission correlated with particular aspects of patient behavior and ability to engage in treatment during the first 6 weeks of hospitalization. These findings have implications for the management of inpatient treatment.
