Meningitis por Streptococcus agalactiae en el anciano / Streptococcus agalactiae meningitis in the elderly

La meningitis bacteriana continúa siendo una enfermedad con una alta mortalidad en ancianos, a pesar de la moderna antibioterapia. En los últimos años, la meningitis bacteriana ha cambiado y es frecuente en adultos, especialmente en ancianos. El déficit de la función inmunológica relacionada con el envejecimiento y la mayor propensión a padecer enfermedades agudas o crónicas comórbidas pueden predisponer a la infección por estreptococos del grupo B en el anciano. Las manifestaciones clínicas pueden ser atípicas en la población geriátrica. La fiebre, la cefalea y la rigidez de nuca pueden estar ausentes. Presentamos un caso de meningitis por Streptococcus agalactiae en una mujer anciana sin factores comórbidos. Debemos tener presente esta enfermedad como posible diagnóstico ante un paciente anciano con confusión o bajo nivel de conciencia. (AU)

[Language comprehension by children with profound congenital deafness after cochlear implant]. / Compréhension du langage par les enfants sourds profonds congénitaux au moyen de l'implant cochléaire.

The consequences of profound deafness on oral language development in children are drastic and well-known. Modern multichannel cochlear implant (CI) has been proven to enhance speech production skills in prelingually deaf children. Speech production skills, however, are known not to be a reliable reflection of oral language competence as a whole. Language is an acquired common code in a specific group, enabling exchange of ideas, feelings and knowledge. In humans, speech is one of the channels conveying language. Assessing language development in CI children is more difficult than simply assessing speech production skills. Many factors may contribute to a poor or an excellent outcome, making it difficult to compare groups of children wearing or not wearing CI. The present study compared receptive language levels in paired matched children from CI and non-CI groups. The main conclusion of this study is that language comprehension scores grow significantly higher over time post-surgery in CI than in paired-matched non-CI children, despite better initial pure tone audiometric thresholds of the latter.

Comprehension of language in congenitally deaf children with and without cochlear implants.

The consequences of profound early deafness on oral language in children are drastic. The modern cochlear implant (CI) has been shown to enhance speech production skills in prelingually deaf children. Many factors may contribute to a poor or an excellent outcome, making it difficult to compare groups of children wearing or not wearing cochlear implants. The present study compared receptive language levels in matched pairs of children from CI group and non-CI groups. The pre-op receptive language development curve suggest a possible growth over time with the maturation and the speech therapy. Comparison showed that the slope for post-op CI children to be greater than for non-CI children, and that this difference is statistically significant, and that the slope for CI children to be greater post- than pre-operatively. The main conclusion is that receptive language scores grow significantly higher over time after surgery in CI than in pair-matched non-CI children, despite better initial pure tone audiometric thresholds of the latter.
