Is joint hypermobility associated with vesico-ureteral reflux? An assessment of 50 patients (Article)

2011-08-29T00:00:00Z

Study Type - Aetiology (individual cohort) Level of Evidence2b What's known on the subject? and What does the study add? Recent studies have already shown associations between generalized joint hypermobility (GJH) and voiding and defecation dysfunction and/or slow transit constipation. Changes in extracellular matrix composition in vesico-ureteric junction of vesico-ureteral reflux (VUR) patients were also observed previously. This study is the first to assess joint mobility as a parameter for connective tissue composition in vesico-ureteral reflux. We convincingly demonstrate that VUR patients have significantly more hypermobile joints compared to controls and this provides a new angle to the intriguing subjects of development of VUR and susceptibility to VUR. Objective: To assess whether there is an increased prevalence of joint hypermobility in patients with vesico-ureteric reflux (VUR). Materials And Methods: We studied 50 patients with primary VUR and matched controls drawn from a reference population. Joint mobility was assessed using the Bulbena hypermobility score. RESULTS: We identified significantly more patients with VUR with generalized joint hypermobility than controls (24% vs 6.7%, P= 0.007). Conclusion: Our findings confirm our clinical observation of an increased rate of joint hypermobility in patients with VUR. We speculate that an altered composition of the connective tissue may contribute to the severity of the (pre-existing) VUR phenotype. © 2011 THE AUTHORS. BJU INTERNATIONAL

Six-minute walking test in children with ESRD: Discrimination validity and construct validity (Article)

2009-07-27T00:00:00Z

The six-minute walking test (6MWT) may be a practical test for the evaluation functional exercise capacity in children with end-stage renal disease (ESRD). The aim of this study was to investigate the 6MWT performance in children with ESRD compared to reference values obtained in healthy children and, secondly, to study the relationship between 6MWT performance with anthropometric variables, clinical parameters, aerobic capacity and muscle strength. Twenty patients (13 boys and seven girls; mean age 14.1 ± 3.4 years) on dialysis participated in this study. Anthropometrics were taken in a standardized manner. The 6MWT was performed in a 20-m-long track in a straight hallway. Aerobic fitness was measured using a cycle ergometer test to determine peak oxygen uptake (V̇O2peak), peak rate (Wpeak) and ventilatory threshold (VT). Muscle strength was measured using hand-held myometry. Children with ESRD showed a reduced 6MWT performance (83% of predicted, p < 0.0001), irrespective of the reference values used. The strongest predictors of 6MWT performance were haematocrit and height. Regression models explained 59% (haematocrit and height) to 60% (haematocrit) of the variance in 6MWT performance. 6MWT performance was not associated with V̇O2peak, strength, or other anthropometric variables, but it was significantly associated with haematocrit and height. Children with ESRD scored lower on the 6MWT than healthy children. Based on these results, the 6MWT may be a useful instrument for monitoring clinical status in children with ESRD, however it cannot substitute for other fitness tests, such as a progressive exercise test to measure V̇O2peak or muscle strength tests.

Physical fitness in children with haemophilia and the effect of overweight (Article)

2009-04-03T00:00:00Z

Although children with haemophilia are advised to participate in physical activities, their physical fitness has not been studied in a large group. In addition, children with haemophilia may be at increased risk for becoming overweight as a result of inactivity because of joint bleedings or because of overprotection. This study aimed to assess physical fitness (aerobic capacity), joint status, muscle strength, quality of life (QoL), self-reported motor competence and also prevalence of overweight and its association with physical parameters. Weight and height were measured. Skin folds were measured unilaterally at biceps, triceps, subscapular and supra-iliac sites. Aerobic capacity was determined on a cycle ergometer or with a 6-min walk test (6MWT). Muscle strength and active range of motion of elbows, knees and ankle joints were measured. Self-reported motor competence was measured with the 'Competentie BelevingsSchaal voor Kinderen'. Joint pain was scored on a Visual Analogue Scale. The Haemo-QoL Index was used to measure QoL. In 158 Dutch boys with haemophilia, with a mean age of 12.7 years (SD 2.9), normal aerobic capacity and muscle strength were found. Joint pain was reported by 16% of the participants. The prevalence of overweight (16%) was slightly increased when compared with healthy Dutch boys (13.5%). Being overweight had a negative association with the 6 MWT and QoL. Dutch children with haemophilia have normal aerobic exercise capacity and muscle strength. The majority also has normal joint mobility. Prevalence of overweight is slightly increased.

Exercise training in pediatric patients with end-stage renal disease (Article)

2009-01-01T00:00:00Z

The objective of this study was to determine the feasibility and efficacy of an exercise training program to improve exercise capacity and fatigue level in pediatric patients with end-stage renal disease (ESRD). Twenty children on dialysis intended to perform a 12-week graded community-based exercise program. Exercise capacity and fatigue level were studied; muscle force and health-related quality of life were secondary outcomes. All outcomes were measured at baseline (T = 0) and after intervention (T = 1). Fourteen of the 20 patients (70%) either did not start the program or did not complete the program. Of these patients, seven did not complete or even start the exercise program because of a combination of lack of time and motivational problems. Six patients were not able to continue the program or were unable to do the follow-up measurements because of medical problems. Exercise capacity and muscle strength was higher after the exercise program in the children who completed the training. In conclusion, exercise training is difficult to perform in children with ESRD and is not always feasible in real-life situations for many children with ESRD.

Torticollis and plagiocephaly in infancy: Therapeutic strategies (Article)

2006-01-01T00:00:00Z

Background. Asymmetry in infancy is a diagnosis with a large spectrum of features, expressing an abnormal shape of parts of the body or unequal postures and movements, which might be structural and/or functional, with localized or generalized expression. Purpose: The purpose of the present study is to highlight different therapeutic aspects of the most occurring asymmetries in infancy: congenital muscular torticollis, positional torticollis and plagiocephaly, based on best evidence in current literature. Results: A flow chart is presented showing different pathways in therapeutic strategies, such as physical therapy, orthotic devices (helmet treatment and Dynamic Orthotic Cranioplasty) and surgery. Conclusion: It is concluded that there are different views towards management on torticollis and plagiocephaly. A systematic therapeutic management to evaluate these asymmetries is indicated. The presented therapeutic flow chart might serve as a basis in order to achieve uniformity in therapeutic thinking and performance.
