Autosomal Dominant Inheritance of Centrotemporal Sharp Waves in Rolandic Epilepsy Families

EPILEPSIA, Issue 12 2007
Bhavna Bali
Summary Purpose: Centrotemporal sharp (CTS) waves, the electroencephalogram (EEG) hallmark of rolandic epilepsy, are found in approximately 4% of the childhood population. The inheritance of CTS is presumed autosomal dominant but this is controversial. Previous studies have varied considerably in methodology, especially in the control of bias and confounding. We aimed to test the hypothesis of autosomal dominant inheritance of CTS in a well-designed family segregation analysis study. Methods: Probands with rolandic epilepsy were collected through unambiguous single ascertainment. Siblings in the age range 4,16 years underwent sleep-deprived EEG; observations from those who remained awake were omitted. CTS were rated as present or absent by two independent observers blinded to the study hypothesis and subject identities. We computed the segregation ratio of CTS, corrected for ascertainment. We tested the segregation ratio estimate for consistency with dominant and recessive modes of inheritance, and compared the observed sex ratio of those affected with CTS for consistency with sex linkage. Results: Thirty siblings from 23 families underwent EEG examination. Twenty-three showed evidence of sleep in their EEG recordings. Eleven of 23 recordings demonstrated CTS, yielding a corrected segregation ratio of 0.48 (95% CI: 0.27,0.69). The male to female ratio of CTS affectedness was approximately equal. Conclusions: The segregation ratio of CTS in rolandic epilepsy families is consistent with a highly penetrant autosomal dominant inheritance, with equal sex ratio. Autosomal recessive and X-linked inheritance are rejected. The CTS locus might act in combination with one or more loci to produce the phenotype of rolandic epilepsy. [source]


Reliability and comparability of a Spanish-language form of the preschool and kindergarten behavior scales

Amy G. Carney
Comparability of a Spanish language translation of the Preschool and Kindergarten Behavior Scales was examined in relation to the English language version. Children ages 3,6 enrolled in preschool, kindergarten, or Head Start programs were rated concurrently by respondents on English and Spanish versions of the PKBS. Results showed virtually identical internal consistency of scores on both forms on Social Skills (.93) and Problem Behavior (.96) Scales. Correlations between forms for Social Skills and Problem Behavior scores were .93 and .94, respectively. Implications of these findings, directions for future research and the importance of continued work toward development/translation of other Spanish language assessment instruments for the early childhood population are discussed. © 2002 Wiley Periodicals, Inc.

Regional variation in celiac disease risk within Sweden revealed by the nationwide prospective incidence register

ACTA PAEDIATRICA, Issue 2 2009
Cecilia Olsson
Abstract Aim: To determine if there is any regional celiac disease (CD) risk variation in the Swedish childhood population. Methods: Prospective nationwide Swedish incidence register of CD in children 0,15 years of age, with the present analysis covering the period from 1998 to 2003. ESPGHAN diagnostic criteria for CD were used. Regions were classified according to the Nomenclature of Territorial Units for Statistics. The incidence rate for each region, gender, age group and year of diagnosis was calculated. Results: A regional variation in CD risk was demonstrated. The childhood populations in ,West Sweden' and ,Småland and the islands', situated in the southern part of the country, had a significantly higher incidence rate compared to in ,North Middle Sweden' and ,Stockholm', situated in the central part. This regional variation was not explained by variations in risk by gender, age at diagnosis or year of diagnosis. Conclusion: The Swedish regional variation in CD risk supports multifactorial disease aetiology. Continued efforts are warranted to define factors, besides gluten exposure, that modulate CD risk.

Language preference and its relationship with reading skills in English and Spanish

PSYCHOLOGY IN THE SCHOOLS, Issue 2 2007
Michele H. Brenneman
A dearth of research has investigated the language preference of bilingual childhood populations and its subsequent relationship to reading skills. The current study evaluated how a sequential bilingual student's choice of language, in a particular environmental context, predicted reading ability in English and Spanish. The participants were Latino children ranging in age from 7 years, 5 months, to 11 years, 6 months, with 43% born in the United States. Results showed a relationship between a child's higher English language preference for media and for communication with others outside the family and better reading skills in English. Language preference differences predicted reading abilities better for English than for Spanish. Results suggested that sequential bilingual children's language preference may be a useful marker of English language (second language [L2]) facility and use that is related to their reading proficiency or influences the development of English reading skills in such bilingual children in the United States. © 2007 Wiley Periodicals, Inc.
