Parent relationships and compliance in cystic fibrosis

BACKGROUND: Olfactory dysfunction is one of the major complaints in patients suffering from allergic rhinitis. Little is known about the onset of hyposmia in seasonal allergy. METHODS: We performed two prospective studies to examine olfactory function in allergic rhinitis using an established (modified CCCRC) test for olfactory threshold, identification and discrimination. RESULTS: In a pilot study the time-course of olfactory function in 14 patients with allergic rhinitis to grass pollen was examined at the beginning of the season. Olfactory function was evaluated birhinal on day 3, 7, 14, and 21 of the season. Preseasonally, all patients were normosmic. There was a significant decrease in threshold and identification between the third and fourteenth day of the season, resulting in a moderate hyposmia in the mean. Hyposmia was not correlated to subjective symptom of nasal blockage. Therefore, a follow-up study was performed on 17 patients and a control group with a similar study design including measurements of nasal volume flow (rhinomanometry) and an inflammatory cell activation marker (ECP) in nasal secretions. The time-course of the olfactory changes was much better correlated to the inflammatory measure than to nasal volume flow. CONCLUSIONS: Patients with allergic rhinitis develop a significant olfactory dysfunction under allergen exposition. Inflammatory dysfunction of the olfactory epithelium seems to be more important than respiratory dysfunction in the pathomechanism of allergic hyposmia.     

In vitro fertilization and the family: Quality of parenting, family functioning, and child psychosocial adjustment.

This study examined associations between homologous in vitro fertilization (IVF) and quality of parenting, family functioning, and emotional and behavioral adjustment of 3–7-year-old children. A cross-sectional survey was conducted in Taiwan with 54 IVF mother–child pairs and 59 mother–child pairs with children conceived naturally. IVF mothers reported a greater level of protectiveness toward their children than control mothers. Teachers, blind to condition, rated IVF mothers as displaying greater warmth but not overprotective or intrusive parenting behaviors toward their children. Teachers scored children of IVF as having fewer behavioral problems than control children. In contrast, IVF mothers reported less satisfaction with aspects of family functioning. Family composition moderated parenting stress: IVF mothers with only 1 child perceived less parenting stress than did those in the control group.

Colonic strictures in children with cystic fibrosis

PURPOSE: To determine the radiographic, clinical, surgical, and histologic findings in children with cystic fibrosis who develop strictures of the colon. MATERIALS AND METHODS: Ten children (five boys, five girls; age range, 2.5-9.0 years; mean age, 5.5 years), who were treated at the practices of the authors, were retrospectively identified and their medical records reviewed. RESULTS: Radiographic manifestations of the colonic disease included mucosal irregularity and spiculation with nodular thickening of the colonic wall and loss of normal colonic haustration. Luminal narrowing involved long segments of the colon. Longitudinal shortening of the colon was also a prominent feature. The decrease in caliber of the bowel ranged from mild narrowing to complete occlusion of the lumen. Histologic examination revealed severe submucosal fibrosis and fatty infiltration with transmural extension of the fibrosis to involve the serosa in some cases. Unlike in Crohn disease, however, acute inflammatory changes were minimal or absent. CONCLUSION: Colonic stricture in children with cystic fibrosis is due to irreversible and frequently progressive narrowing of the colonic lumen.     

Psychosocial functioning of young adults with cystic fibrosis and their families

BACKGROUND: The psychosocial functioning of adolescents and young adults with cystic fibrosis still living in the parental home was investigated. With its proven genetic aetiology cystic fibrosis is an ideal model with which to assess the impact of a chronic and life threatening disorder on family and individual psychological and social functioning. METHODS: Twenty nine patients with cystic fibrosis and their families were compared with those of 27 patients with anorexia nervosa and 31 well controls. Assessments were made using self reporting, interview, and observational methods. RESULTS: Most patients with cystic fibrosis were in robust psychological health and only differed from their healthy peers in that they were much less likely to be in employment. Mothers of patients with cystic fibrosis or anorexia nervosa were more likely than the mothers of the well group to be emotionally distressed, although this was not so for fathers. Young people in both illness groups were more likely to have parents with high levels of expressed emotion. Most families of patients with cystic fibrosis had good problem solving abilities. CONCLUSIONS: In spite of the burden of illness in cystic fibrosis psychological functioning in many respects matches that of well young people.     

Fibrosing colonopathy in children with cystic fibrosis

PURPOSE: Fibrosing colonopathy is a newly described entity seen in children with cystic fibrosis. The radiological hallmarks are foreshortening of the right colon with varying degrees of stricture formation. High-dose enzyme therapy has been implicated as the cause of this process. The purpose of this study is to review the author's experience with evaluation and treatment of these patients. METHODS: There are currently 380 patients being treated at our CF center. Fifty-five of these patients have been treated with high-dose enzyme therapy (> 5,000 units of lipase/kg). The medical records of these patients, who are at risk for developing fibrosing colonopathy, were reviewed for the presence of recurrent abdominal complaints, and the work-up and treatment of these symptoms. RESULTS: Chronic complaints of abdominal pain, distension, change in bowel habits, or failure to thrive were present in 24 of the 55 patients treated with high-dose enzymes. So far, 18 of these 24 patients have been evaluated by contrast enema. Thirteen of eighteen have been found to have fibrosing colonopathy characterized by foreshortening and strictures of the colon. Additional findings included focal strictures of the right colon (7 of 13), long segment strictures (5 of 13), and total colonic involvement (1 of 13). Nine patients with the most severe symptoms have undergone colon resection, including five segmental right colectomies, three extended colectomies (ileo-sigmoid anastomosis), and one subtotal colectomy with end-ileostomy. Pathological evaluation has shown submucosal fibrosis, destruction of the muscularis mucosa, and eosinophilia. No postoperative complications or deaths occurred. All nine postoperative patients have noted marked symptomatic improvement. Contrast enema follow-up results are available for six patients, and have documented no recurrent strictures to date. Three of four nonoperative patients have less severe symptoms and are currently being treated conservatively. The other family has refused surgery and the patient is being treated symptomatically. CONCLUSION: High-dose lipase replacement has been implicated as the etiology for FC and was present in all of our patients. Our cystic fibrosis center now routinely limits lipase to 2,500 U/kg per dose. We recommend the use of the contrast enemas to evaluate at-risk patients who have chronic abdominal complaints or who present with recurrent bowel obstruction. Colon resection should be performed in those with clinically and radiographically significant strictures with the expectation of a good outcome.     

The psychosocial functioning and family environment of depressed adolescents

OBJECTIVE: This study examined measures of functional impairment and family relations in a sample of 62 adolescents with major depressive disorder (MDD) and 38 normal controls with no history of psychiatric illness. METHOD: Ratings of the following domains were obtained: mother-child relations, father-child relations, spousal relations, sibling relations, peer relations, and school performance. Ratings of each domain for the 3-month period preceding the assessment were derived from information obtained using a semistructured interview administered independently to the adolescents and one of their parents. RESULTS: Adolescents with MDD were found to have severe difficulties in all areas. Ninety percent of the depressed adolescents had scores greater than 2 SD above the mean of the normal controls on one or more of the domain ratings. In addition, adolescents with difficulties in parent-child relations were more likely than those adolescents without problems in family relations to have difficulties in peer relations and school performance. CONCLUSIONS: The authors discuss the importance of systematically examining psychosocial variables in future studies of the etiology, course, and treatment of MDD in adolescents.     

Lung disease in mice with cystic fibrosis

The leading cause of mortality and morbidity in humans with cystic fibrosis is lung disease. Advances in our understanding of the pathogenesis of the lung disease of cystic fibrosis, as well as development of innovative therapeutic interventions, have been compromised by the lack of a natural animal model. The utility of the CFTR-knockout mouse in studying the pathogenesis of cystic fibrosis has been limited because of their failure, despite the presence of severe intestinal disease, to develop lung disease. Herein, we describe the phenotype of an inbred congenic strain of CFTR-knockout mouse that develops spontaneous and progressive lung disease of early onset. The major features of the lung disease include failure of effective mucociliary transport, postbronchiolar over inflation of alveoli and parenchymal interstitial thickening, with evidence of fibrosis and inflammatory cell recruitment. We speculate that the basis for development of lung disease in the congenic CFTR-knockout mice is their observed lack of a non-CFTR chloride channel normally found in CFTR-knockout mice of mixed genetic background.     

Degree of burn, location of burn, and length of hospital stay as predictors of psychosocial status and physical functioning

Bronchogenic carcinoma is the most frequent carcinoma of men and affect more often old patients. Medical oncologists and pneumologists don't treat or treat with less intensive therapies patients older than 70 or 75 years compared with younger patients. That behaviour is not based on scientific criterias. The majority of the published studies are in fact retrospective with a lot of biases (especially selection of patients). It doesn't seem that nephrotoxicity is greater in older patients with cisplatinum but the neurological, digestive and medullary toxicities are more important in older than in younger patients.     

Correlates of alcohol use and misuse in fourth-grade children: psychosocial, peer, parental, and family factors

To determine level of alcohol use/misuse and to examine correlates of these behaviors, 1,314 fourth-grade students were surveyed. The questionnaire included 55 items concerning tolerance of deviance, deviant self-image, self-efficacy, susceptibility to peer pressure, personal and peer approval of alcohol use, peer adjustment, parent nurturance and monitoring, family adjustment, parental permissiveness, peer use of alcohol, and exposure to alcohol. The items were factor analyzed and indices constructed. The indices generally had acceptable alpha coefficients (alpha = .61-.91); two exceptions were peer adjustment (alpha = .51) and parental permissiveness (alpha = .42). Tolerance of deviance, deviant self-image, susceptibility to peer pressure, personal and peer approval, peer use and exposure by peers, and parental permissiveness were positively correlated with alcohol use/misuse. Self-efficacy, child-parent interactions, family adjustment, and peer adjustment were negatively correlated with alcohol use/misuse. Implications for the design of family-based alcohol use/misuse prevention programs are discussed.     

Modeling longitudinal change in the language abilities of children with autism: Parent behaviors and child characteristics as predictors of change.

The objective of the current study was to evaluate the patterns of longitudinal change in the language abilities of 28 children with autism during early and middle childhood. Results from fitting a series of multilevel models showed that children's rate of language growth was independently predicted by (a) children's responsiveness to others' bids for joint attention and (b) parents' responsiveness to their children's attention and activity during play. Both predictive relations could not be explained by initial variation in global developmental characteristics, such as IQ, mental age, or language abilities. These findings support a social?pragmatic view on language acquisition, which emphasizes the collaborative process through which children and their parents negotiate shared meaning.

A genetically informed study of associations between family functioning and child psychosocial adjustment.

Research has documented associations between family functioning and offspring psychosocial adjustment, but questions remain regarding whether these associations are partly due to confounding genetic factors and other environmental factors. The current study used a genetically informed approach, the Children of Twins design, to explore the associations between family functioning (family conflict, marital quality, and agreement about parenting) and offspring psychopathology. Participants were 867 twin pairs (388 monozygotic; 479 dizygotic) from the Twin and Offspring Study in Sweden, their spouses, and children (51.7% female; M = 15.75 years). The results suggested associations between exposure to family conflict (assessed by the mother, father, and child) and child adjustment were independent of genetic factors and other environmental factors. However, when family conflict was assessed using only children's reports, the results indicated that genetic factors also influenced these associations. In addition, the analyses indicated that exposure to low marital quality and agreement about parenting was associated with children's internalizing and externalizing problems and that genetic factors also contributed to the associations of marital quality and agreement about parenting with offspring externalizing problems.

Comprehensive analysis of risk factors for acquisition of Pseudomonas aeruginosa in young children with cystic fibrosis

Racial differences in insulin secretion and insulin sensitivity in healthy children were studied by administering a 2-hour hyperglycemic clamp (225 mg/dL) to 14 black and 16 white healthy adolescents (Tanner II-V), and 12 black and 11 white prepubertal children, matched for age, body mass index, and Tanner I pubertal development. In prepubertal children, fasting and first-phase insulin concentrations were higher in blacks compared with whites (14.7+/-1.3 vs 10.4+/-1.2, P=0.02, and 76.9+/-6.8 vs 52.1+/-6.4 microu/mL, P=0.016). There were no differences in second-phase insulin levels and insulin sensitivity index. In pubertal adolescents, first-phase and second-phase insulin concentrations were higher in blacks compared with whites (first-phase: 157.3+/-18.3 vs 77.0+/-8.7 microu/mL, P=0.0003; second-phase: 175.0+/-24.3 vs 108.7+/-8.8 microu/mL, P=0.012). Insulin sensitivity index was 35% lower in black adolescents compared with whites (P=0.02). These findings indicate that significant differences in insulin secretion and sensitivity are detectable early in childhood in healthy African-American vs American whites. However, genetic (race) vs environmental factors (physical activity/fitness, energy balance) should be carefully scrutinized as potential factors responsible for such differences.     

Current and past depression as predictors of family functioning: A comparison of men and women in a community sample.

The association between family functioning and parental depression has primarily been studied in samples of women. In particular, very little research exists that examines how parent gender and past diagnoses of depression are related to family functioning. The family relationships of 469 couples from a community sample were examined using self- and partner report measures of the marital relationship and youth report and interviewer-rated measures of the parent-youth relationship. Both currently and formerly depressed men and women were shown to have poorer family functioning than nondepressed and never depressed individuals, respectively. Interactions of gender and depression status indicated that depression and poorer marital functioning were more strongly related for women than for men, but there were few gender differences in the parent-youth relationship. The results highlight the need for further research on men's family functioning and suggest that targeting current depressive symptoms in treatment may not be sufficient to resolve marital and parent-youth difficulties that endure after depressive episodes remit.

Electrodermal nonresponding, premorbid adjustment, and symptomatology as predictors of long-term social functioning in schizophrenics.

The hypothesis that electrodermal nonresponsiveness to orienting stimuli delineates a core group of "Kraepelinian" type schizophrenics was tested by following up social functioning outcome over a 2-year period in 37 schizophrenics. Good social functioning outcome required both some self-supporting ability in the job market and a minimal social life. The prior assessments included monitoring of electrodermal responses to a series of moderately intense tones, ratings of reported and observed symptoms during an interview, and ratings of premorbid adjustment on the basis of an interview with a close relative. Electrodermal nonresponding, poor premorbid adjustment, and negative symptomatology predicted poor social functioning during the second follow-up year, but the relationship to nonresponding pertained exclusively to a group of 15 first-episode patients. Discriminant analysis showed that electrodermal nonresponding and symptoms were the only independent predictors of outcome. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Family status, family constellation, and home environmental variables as predictors of cognitive performance of Mexican American children.

Examined the relative contributions of several family status variables (child and parental language, parental schooling attainment and location, and SES), a family constellation variable (family size), and the Henderson Environmental Learning Process Scale (HELPS) to the prediction of cognitive performance among 140 Mexican-American preschool children (aged 38–71 mo) from low-income backgrounds. Ss were administered the McCarthy Scales of Childrens' Abilities (MSCA). A factor analysis of the family status and constellation variables produced 3 factors. The General Cognitive Index (GCI) of the MSCA was predicted by multiple regression procedures. The 3 status/constellation factors and HELPS served as independent variables. As hypothesized, the best predictor of GCI was HELPS. A Language/Schooling factor made an additional significant contribution to the explained variance. The theoretical and practical implications of including proximal as well as distal background variables in future research on relations between family characteristics and intellectual performance are discussed.

Contemporary psychosocial issues in cystic fibrosis: treatment adherence and quality of life

This review focuses on the two major psychosocial areas currently topical in cystic fibrosis research: treatment adherence and quality of life. First, the paper discusses the importance of evaluating adherence to treatments and medical advice, its measurement, predictors of adherence and non-adherence and whether the data should be used to inform clinical practice and policy decisions. Second, the purpose of evaluating quality of life in cystic fibrosis and an overview of the data are discussed. Both areas have suffered from problems with terminology and definition, inappropriate methodologies and hence difficulties with data interpretation. Future directions for research are advocated.     

Psychological, family, and peer predictors of academic outcomes in first- through fifth-grade children.

This study tested a model that posited that 3 diverse sets of academic outcomes (memory, verbal, and nonverbal aptitudes [N?=?521]; passing proficiency tests in reading and mathematics [N?=?122]; and end-of-year ratings of verbal and mathematical skills by teachers [N?=?159]) for 1st- through 5th-grade children were uniquely determined by psychological (verbal and visual-motor "school readiness" skills at kindergarten, cognitive self-control, and academic self-competence), family (behavioral involvement of an adult family member in the child's schooling), and peer (the average academic performance of members of one's peer group) factors. Verbal readiness skills were uniquely linked to 5 of the 7 academic outcomes. An outcome-specific view of what sets of factors are linked to academic performance was favored in that, of the 5 predictors, only school readiness accounted for unique portions of the variance in aptitudes; only school readiness and cognitive self-control accounted for unique portions of the variance in whether proficiency tests were passed; and only school readiness, cognitive self-control, and the academic performance of one's peer group accounted for unique portions of the variance in end-of-year ratings.
