Developmental trajectories of early communication skills.

2012

Purpose This study focused on developmental trajectories of prelinguistic communication skills and their connections to later parent-reported language difficulties. Method The participants represent a subset of a community-based sample of 508 children. Data include parent reports of prelinguistic communication skills at 12, 15, 18, and 21 months and language difficulties at age 4;7 (years;months). The authors used latent profile analysis to identify groups of children with differing developmental trajectories of prelinguistic communication skills ( n = 271). The relations among these groups and follow-up data of parent-reported concerns of language development ( n = 187), as well as the ro…

Continuity From Prelinguistic Communication to Later Language Ability: A Follow-Up Study From Infancy to Early School Age.

2016

Purpose This longitudinal study examined the development of prelinguistic skills and the continuity of communication and language from the prelinguistic stage to school age. Method Prelinguistic communication of 427 Finnish children was followed repeatedly from 6 to 18 months of age ( n = 203–322 at ages 6, 9, 12, 15, and 18 months), and its associations with language ability at ages 2;0 ( n = 104), 3;0 ( n = 112), 4;7 ( n = 253), 5;3 ( n = 102), and 7;9 ( n = 236) were examined using latent growth curve modeling. Results Prelinguistic development across several skills emerged as a rather stable intraindividual characteristic during the first 2 years of life. Continuity from prelinguistic …

Orthodontic treatment stability predictors: A retrospective longitudinal study

2016

ABSTRACTObjective: To examine medium- to long-term orthodontic treatment stability and its possible association with certain variables.Materials and Methods: In a retrospective longitudinal study of 70 postretention patients, the Peer Assessment Rating (PAR) index was measured at the start (T1) and end (T2) of treatment and between 4 and 10 years afterwards (T3). The stability was considered absolute when the T2 and T3 values were identical and relative when the difference was within the ±5 range.Results: Among the 70 patients, 65.8% were female and 34.2% were male. Their mean age was 14.5 years. The mean treatment length was 2.4 years. The mean retention phase was 3.3 years. The mean pre- …

Difference in physical fitness in children with initially high and low gross motor competence: A ten-year follow-up study

2018

Abstract The aim of the study was to investigate the difference in relative physical fitness between children with initially high and low gross motor competence in a ten-year prospective study. A sample of 49 children from a local primary school was tested on gross motor competence and physical fitness in 1st grade (5/6 years old). The children were tested again in 2nd (motor competence only), 7th, and 10th grade (15/16 years old). The sample was divided into two groups; initially high and low gross motor competence, according to score (median-split) on the Korperkoordinationstest fur Kinder-test battery in 1st grade. Results suggested that the initially high gross motor competence-group pe…

Healing of intrabony defects following treatment with a bovine-derived xenograft and collagen membrane

2003

Objectif: L'objectif de cette etude etait de comparer cliniquement le traitement de lesions intra-osseuses profondes avec xenogreffe d'origine bovine (BDX) associe a une membrane collagene bioresorbable pour acceder a la chirurgie a lambeau. Methode: Vingt-huit malades souffrant de parodontite chronique, chacun montrant une lesion intra-osseuse ont ete traites au hasard au BDX+membrane collagene (essai) ou avec chirurgie a lambeau (controle). Les mesures des tissus mous ont ete prises au depart et 1 an apres la therapie. Resultats: Aucune difference dans aucun des parametres etudies n'a ete observee au depart entre les deux groupes. La cicatrisation a ete sans incident pour tous les malades…

Widespread pain among 11-year-old Finnish twin pairs

2001

Objective To examine the prevalence of widespread musculoskeletal pain (WSP) symptoms in 11-year-old Finnish twins and to determine the relative role of genetic and environmental factors in the etiology of WSP. Methods Data on current pain items were collected from 1995 to 1998 from a national sample of Finnish families with 11-year-old twins born between 1984 and 1987. The presence of WSP was determined using a validated questionnaire method. Pairwise similarity was computed for 583 monozygotic (MZ) pairs, 588 same-sex dizygotic (DZ) pairs, and 618 opposite-sex DZ twin pairs. Variance components for genetic and environmental factors were estimated using biometric structural equation modeli…

Associations of Physical Activity and Sedentary Behavior with Academic Skills – A Follow-Up Study among Primary School Children

2014

Background There are no prospective studies that would have compared the relationships of different types of physical activity (PA) and sedentary behavior (SB) with academic skills among children. We therefore investigated the associations of different types of PA and SB with reading and arithmetic skills in a follow-up study among children. Methods The participants were 186 children (107 boys, 79 girls, 6–8 yr) who were followed-up in Grades 1–3. PA and SB were assessed using a questionnaire in Grade 1. Reading fluency, reading comprehension and arithmetic skills were assessed using standardized tests at the end of Grades 1–3. Results Among all children more recess PA and more time spent i…

Externalizing Problem Behaviors and Headache: A Follow-up Study of Adolescent Finnish Twins

2004

Objective.To examine the association of teacher- and parent-rated behavior with headache in a prospective follow-up study of adolescent Finnish twins.Methods.Questionnaire data were collected during 1995–2001 from a nationwide sample of Finnish families of 11-year-old twins who were born 1983–1987 (n = 5393) and again at age of 14. Psychological factors were measured by using parents’ and teachers’ ratings of a 37-item multidimensional rating instrument at the ages of 11 and 14.Results.At age 11, headache frequency (5 categories) was associated with total scales of externalizing and internalizing problem behaviors and adaptive behaviors, assessed by parents, but only with externalizing prob…

The face lift SMAS plication flap for reconstruction of large temporofrontal defects: reconstructive surgery meets cosmetic surgery.

2011

Background: Reconstruction of large defects in the temporal region can be performed with skin grafts or pedicled or free flaps. Results are often not optimal because of the patch of a skin graft, lack of availability of local flaps, and distant skin from free flaps. A technique for reconstruction of these defects with local tissue is presented in this article that uses superficial musculoaponeurotic system (SMAS) plication to allow wide advancement of a cervicofacial flap. Methods: Once the defect is outlined, a face-lift–like skin incision is used to raise the flap. The SMAS is plicated with two purse-string sutures that relieve tension on the flap and allow maximal advancement. Thirteen f…
