Genomic characterization of hepatitis C virus isolates from Argentina.

Thirty-three Argentinian patients infected with hepatitis C virus (HCV) were studied for viral genotyping. The patients included 10 hemophiliac and 4 polytransfused children and 19 adults: 3 polytransfused, 7 dialyzed and 9 sporadic cases. Core-based genotyping permitted the classification of 31 samples. Genotypes II, I and V were the most frequent: 21 (63.6%), 16 (48.4%) and 10 (30.3%) of the 33 patients, respectively. Only one polytransfused patient carried genotype IV. Genotype II was detected in 7 out of 9 sporadic cases. Thirteen patients (39.3%) were coinfected with two genotypes, and 2 others were coinfected with three genotypes. The remaining 2 samples which could not be typed were characterized following the restriction fragment length polymorphism (RFLP) method, and were classified as type 1. One of these had two consecutive transitional mutations in the 5' untranslated region (5' UTR).

Parents' speech and children's stuttering: a critique of the literature.

The role of parents in relation to their children's stuttering has been of great interest to speech-language pathologists for more than 50 years. As part of treatment, speech-language pathologists frequently advise parents to modify their speech behaviors when talking with their children. For example, parents are often told to speak more slowly and to refrain from interrupting or questioning the child excessively. Given the commonness of this advice, it is important to examine the research upon which it is based. This article contains a critical review of the literature concerning the role of parents' speech behaviors (e.g., rate, interruptions, question-asking) in relation to their children's stuttering. Published studies are reported and analyzed in order to determine the extent to which parents may affect their children's stuttering through their own speech behaviors. The review indicates that there is little convincing evidence to support the view that parents of children who stutter differ from parents of children who do not stutter in the way they talk with their children. Similarly, there is little objective support for the argument that parents' speech behaviors contribute to children's stuttering or that modifying parents' speech behaviors facilitates children's fluency. Implications for treatment and for future research are discussed.

Familiarity and transparency in idiom explanation: a developmental study of children and adolescents.

Idioms differ widely in their degree of difficulty for children and adolescents. Two factors that might account for these differences, familiarity and transparency, were examined. Children and adolescents ages 11, 14, and 17 years (N = 150) were asked to explain in writing the meanings of 24 different idiomatic expressions, each presented in a brief story context. Results showed that performance on the task gradually improved as subject age increased and that high-familiarity idioms were generally easier to explain than moderate- or low-familiarity expressions. Easier idioms also tended to be more transparent. The results are consistent with the "language experience" view of figurative development and question the hypothesis that idioms are learned as giant lexical units.
