Phenotype of two Consanguineous Autosomic Recessive Retinitis Pigmentosa Families Caused by PDE6A and PDE6B Mutations

Purpose: To assess the clinical phenotype in two consanguineous Tunisian families with non syndromic autosomic recessive retinitis Pigmentosa (RP) caused by a PDE6A and PDE6B mutations.Methods: All accessible familiy members were included. Affected members from each family underwent full ophthalmic examination with best corrected Snellen visual acuity, fundus photography, optical coherence tomography and full field electroretinography. Haplotype analyses were used to test linkage in the family to 20 arRP loci, including ABCA4, LRAT, USH2A, RP29, CERKL, CNGA1, CNGB1, CRB1, EYS, RP28, MERTK, NR2E3, PDE6A, PDE6B, RGR, RHO, RLBP1, TULP1. All exons and intron-exon junctions of candidate genes not excluded by haplotype analysis were PCR amplified and directly sequenced.Results: Two family members were clinically affected with arRP in each pedigree. Age range at baseline was 43 to 54 years (mean age at baseline was 48 years). For all affected members, night blindness appeared since early childhood (at 4-5 years old) without nystagmus but with a severe progression and mild to severe loss of central vision at the second decade. Visual acuity at baseline ranged from 20/500 to 20/63. Kinetic visual field was severely constricted for one patient and unrealizable for the others. Funduscopic examination revealed bone spicule-shaped pigment deposits in the mid periphery along with atrophy of the retina, narrowing of the vessels and waxy optic discs. Tomograms showed macular atrophy in both cases of family A, and macular edema in the patients of family B. ERG showed a loss of both rod and cone responses. Haplotype analysis revealed homozygosity for microsatellites markers flanking PDE6A and PDE6B in family A and B, respectively. Sequencing of PDE6A in family A showed a homozygous R102S mutation. In family B, sequencing identified a D600N homozygous mutation. Both mutations cosegregated within each respective pedigree.Conclusions: For these families, affected members developed a severe form of non syndromic arRP. The two reported mutations have already been described. Our data further contribute to our understanding of genotype-phenotype correlations.

Devenir parent : divergences et convergences interindividuelles dans une transition de vie

RésuméLa naissance du premier enfant est un événement normatif à l'origine de nombreux changements dans le parcours de vie des hommes et des femmes. La présente recherche s'intéresse à la transition à la parentalité en tant que moment à l'origine d'un processus de stratification sociale. Trois dimensions dépendantes sont étudiées du point de vue de leur changement: l'insertion professionnelle, le travail domestique et la qualité de la relation conjugale. Les concepts de divergence et de convergence interindividuelle, élaborés à partir de l'hypothèse des dés/avantages cumulatifs et de l'hypothèse alternative des effets compensatoires, sont utilisés pour opérationnaliser le changement qui se produit dans ces trois dimensions lors de la naissance du premier enfant.Les résultats montrent, dans un premier moment, la présence de divergences entre les hommes et les femmes dans chacune de ces trois dimensions. Ces divergences inter-sexe sont associées à des convergences entre les individus de même sexe. Les analyses se focalisent dans un deuxième moment, sur les divergences et convergences ultérieures qui se produisent entre individus du même sexe en fonction des ressources sociales, culturelles et économiques initiales. Quelles sont ainsi, par exemple, les mères qui ne diminuent pas leur taux d'occupation initial? Quels sont les pères qui réduisent moins que les autres leur investissement dans le travail domestique? Quels sont les parents qui connaissent une moindre diminution de la qualité de leur relation conjugale? Les réponses données à ces questions montrent comment le processus de stratification sociale au sein d'une cohorte doit être expliqué en relation avec le changement qui se produit lors d'une transition spécifique et non seulement en tant que résultat du simple passage du temps.AbstractThe birth of the first child is a normative event creating important changes in the life course of men and women. This research analyzes the transition to parenthood as a moment creating social stratification. Three dependent dimensions are studied in their change: the occupational career, the domestic labour and the conjugal relationship's quality. The concepts of interindividual divergences and convergence, conceived from the cumulative dis/advantage hypothesis and the alternative hypothesis of compensatory effects, are used to operationalize the change in these three dimensions after the birth of the first child.Results show that, firstly, divergences take place between men and women becoming parents in the three dependent dimensions. Inter-sex divergences are associated to convergence between same-sex individuals. Secondly, the analyses focus on further di/convergences taking place between same-sex individuals, in relation with the initial social, cultural and economical resources. Who are the mothers who will not reduce their initial occupational rates? Who are the fathers who will reduce less than the others their involvement in the domestic tasks? Who are the parents who will experience a less important reduction in their conjugal relationship's quality? The answers to these questions show how the process of social stratification within a cohort has to be explained in relation with the change taking place during a specific transition and not only as a result of the simple passage of time.

Molecular testing for fragile X: analysis of 5062 tests from 1105 fragile X families--performed in 12 clinical laboratories in Spain.

Fragile X syndrome is the most common inherited form of intellectual disability. Here we report on a study based on a collaborative registry, involving 12 Spanish centres, of molecular diagnostic tests in 1105 fragile X families comprising 5062 individuals, of whom, 1655 carried a full mutation or were mosaic, three cases had deletions, 1840 had a premutation, and 102 had intermediate alleles. Two patients with the full mutation also had Klinefelter syndrome. We have used this registry to assess the risk of expansion from parents to children. From mothers with premutation, the overall rate of allele expansion to full mutation is 52.5%, and we found that this rate is higher for male than female offspring (63.6% versus 45.6%; P < 0.001). Furthermore, in mothers with intermediate alleles (45-54 repeats), there were 10 cases of expansion to a premutation allele, and for the smallest premutation alleles (55-59 repeats), there was a 6.4% risk of expansion to a full mutation, with 56 repeats being the smallest allele that expanded to a full mutation allele in a single meiosis. Hence, in our series the risk for alleles of <59 repeats is somewhat higher than in other published series. These findings are important for genetic counselling.

Effectiveness of a pediatric palliative home care team as experienced by parents and health care professionals.

OBJECTIVES: Little data are available on palliative home care for children. The objective of this study was to evaluate the effectiveness of a specialized pediatric palliative home care team (PPHCT) as experienced by parents and health care professionals (HCPs). METHODS: Parents and HCPs involved in the care of terminally ill children who died and whom the PPHCT was in charge of were surveyed with questionnaires focusing on satisfaction with the PPHCT, satisfaction with the course of the dying phase, and the development of anxiety, depression, and prolonged grief disorder. RESULTS: Forty-three parent dyads participated (return rate, 88%). Satisfaction with the PPHCT scored a median of 10 (numeric rating scale, 0-10). The child's death was predominantly experienced as very peaceful (median, 9); 71% died at home. According to parents, involvement of the PPHCT led to highly significant (p<0.001) improvements in the children's symptoms and quality of life, as well as in aspects of communication and administrative barrier reduction. Anxiety was detected in 25% of parents, depression in 19%, and prolonged grief disorder in 13%. HCPs (return rate, 83%) evaluated all investigated care domains (particularly cooperation/communication/family support) as being significantly improved (p<0.001). Thirty-five percent of HCPs felt uncertain concerning pediatric palliative care; 79% would welcome specific training opportunities. CONCLUSIONS: Involvement of a PPHCT is experienced as a substantial improvement of care by parents and HCPs. Coordination of palliative care during the last phase of life appears to be an important quality factor for the home care of dying children and their families.

High heritability of ambulatory blood pressure in families of East African descent.

We estimated the heritability of ambulatory systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure (PP) in east African families with at least 2 hypertensive siblings and living in the Seychelles islands (Indian Ocean). The sample consisted of 314 individuals (147 men and 167 women), both normotensive and hypertensive, from 76 pedigrees (mean+/-SD of 4.1+/-2.8 persons per pedigree). After a 2-week off-treatment period, daytime and nighttime ambulatory blood pressure (BP) was monitored. Office BP was measured with a standard mercury sphygmomanometer. We estimated by maximum likelihood the age- and sex-adjusted heritabilities from the additive polygenic component of the variance of the traits allowing for the presence of other familial correlations. We also adjusted for ascertainment (ie, for the fact that 2 siblings had to be hypertensive) and examined the effect of adjusting for body mass index, 24-hour urinary excretion of sodium and potassium, plasma renin activity, and plasma aldosterone concentration. Heritability estimates (+/-SE) for ambulatory SBP, DBP, and PP were, respectively, 0.37+/-0.12/0.24+/-0.12/0.54+/-0.12 for daytime and 0.34+/-0.13/ 0.37+/-0.15/0.47+/-0.12 for nighttime measurements (P<0.05 for all estimates). Heritability estimates for office SBP, DBP, and PP were, respectively, 0.20+/-0.11, 0.05+/-0.09, and 0.37+/-0.12. Heritability estimates for SBP varied markedly according to whether participants were treated for hypertension at baseline. The present data show that ambulatory BP and PP have a high heritability in families of African descent. They also demonstrate that antihypertensive treatment and the number of BP measurements have a major influence on the heritability estimates.

Serving Iowa Youth and Families with a Youth Development Approach : JJDP Act Formula Grant Application and Three-Year Comprehensive Plan

This report is Iowa’s Three-Year Plan, which serves as the application for federal Juvenile Justice and Delinquency Prevention Act formula grant funding (JJDP Act). The Division of Criminal and Juvenile Justice Planning (CJJP) wrote Iowa’s Three-Year Plan. CJJP is the state agency responsible for administering the JJDP Act in Iowa. Federal officials refer to state administering agencies as the state planning agency (SPA). The Plan was developed and approved by Iowa’s Juvenile Justice Advisory Council. That Council assists with administration of the JJDP Act, and also provides guidance and direction to the SPA, the Governor and the legislature regarding juvenile justice issues in Iowa. Federal officials refer to such state level groups as state advisory groups (SAG’s). The acronyms SPA and SAG are used through this report.

PCR-based isolation of multigene families: lessons from the avian MHC class IIB.

The amount of sequence data available today highly facilitates the access to genes from many gene families. Primers amplifying the desired genes over a range of species are readily obtained by aligning conserved gene regions, and laborious gene isolation procedures can often be replaced by quicker PCR-based approaches. However, in the case of multigene families, PCR-based approaches bear the often ignored risk of incomplete isolation of family members. This problem is most prominent in gene families with highly variable and thus unpredictable number of gene copies among species, such as in the major histocompatibility complex (MHC). In this study, we (i) report new primers for the isolation of the MHC class IIB (MHCIIB) gene family in birds and (ii) share our experience with isolating MHCIIB genes from an unprecedented number of avian species from all over the avian phylogeny. We report important and usually underappreciated problems encountered during PCR-based multigene family isolation and provide a collection of measures to help significantly improving the chance of successfully isolating complete multigene families using PCR-based approaches.

Perinatal assessment of infant, parents, and parent-infant relationship: prematurity as an example.

This article reviews the stresses for parents, infants, and other caregivers during the period surrounding the birth of the premature infant. Principles of assessment of infant discomfort, parental stress, the parent-infant relationship, and the match of the medical caregiving environment to the individual infant's needs are discussed. Relevant tools to aide in these aspects of assessment are reviewed. The role of early assessment as preventive intervention and the indication for subsequent intervention in complicated cases of premature infants and their parents are further discussed. The article offers detailed clinical examples to illustrate these and other points throughout.

Consultation d'urgence/crise pour couples et families: motifs d'urgence et évaluation du traitement [Couples and families emergency/crisis consultation: emergency patterns and treatment assessment]

Since the opening in 2003 of the Couple & Family Consultation Unit (UCCF) at Prangins Hospital, we have met urgent demands and observed that the suffering systems (i.e., couples and families) couldn't face any waiting period. So in 2007 an Emergency/Crisis Facility was created, based on the hypothesis that there is no contra-indication to systemic emergency care, if one understands and structures both crisis and treatment. We studied the suffering population in demand and the emergency/crisis issues and assessed therapy efficiency. Then we observed that treating suffering systems in emergency does produce therapeutic gain in terms of crisis resolution and patients' satisfaction. Those treatments refer to public health issues, as considered the human, social and financial cost of couples/families dysfunctions.
