How fatigue is related to other somatic symptoms.

AIMS: To assess the relation between fatigue and somatic symptoms in healthy adolescents and adolescents with chronic fatigue syndrome/myalgic encephalopathy (CFS/ME). METHODS: Seventy two adolescents with CFS were compared within a cross-sectional study design with 167 healthy controls. Fatigue and somatic complaints were measured using self-report questionnaires, respectively the subscale subjective fatigue of the Checklist Individual Strength (CIS-20) and the Children's Somatization Inventory. RESULTS: Healthy adolescents reported the same somatic symptoms as adolescents with CFS/ME, but with a lower score of severity. The top 10 somatic complaints were the same: low energy, headache, heaviness in arms/legs, dizziness, sore muscles, hot/cold spells, weakness in body parts, pain in joints, nausea/upset stomach, back pain. There was a clear positive relation between log somatic symptoms and fatigue (linear regression coefficient: 0.041 points log somatic complaints per score point fatigue, 95% CI 0.033 to 0.049) which did not depend on disease status. CONCLUSIONS: Results suggest a continuum with a gradual transition from fatigue with associated symptoms in healthy adolescents to the symptom complex of CFS/ME.

Recent developments in clinimetric instruments.

Assessment of impairment and function is essential in order to monitor joint status and evaluate therapeutic interventions in patients with haemophilia. The improvements in the treatment of haemophilia have required the development of more sensitive tools to detect the more minor dysfunctions that may now be apparent. This paper outlines some of the recent developments in this field. The Haemophilia Joint Health Score (HJHS) provides a systematic and robust measure of joint impairment. The MRI Scoring System has been designed to provide a comprehensive scoring system combining both progressive and additive scales. The Functional Independence Score for Haemophilia (FISH) has been developed to assess performance of functional activities and can be used in conjunction with the Haemophilia Activities List (HAL) which provides a self report measure of function. It is recommended that both measures are evaluated as these tools measure different constructs. Further refinement and testing of the psychometric properties of all of these tools is in progress. More widespread use of these tools will enable the sharing of data across the world so promoting best practice and ultimately enhancing patient care.

Physical fitness, functional ability and quality of life in children with severe haemophilia: a pilot study.

In the Netherlands comparable levels of sports-participation between persons with haemophilia and healthy controls have been reported. This raises the question if children with haemophilia under the currently available prophylaxis do reach comparable levels of physical fitness and health-related quality of life (HRQoL) as their healthy peers. The aim of this study was to investigate the level of physical fitness, functional ability and quality of life and to determine the feasibility to safely test the exercise capacity of boys with severe haemophilia A. Thirteen subjects participated in this study. Physical fitness was determined using the measurement of maximal oxygen uptake (VO2peak) attained during a graded maximal exercise test to volitional exhaustion. Joint health, physical activity levels and health-related quality of life (Haemo-Qol) were also measured. Mean VO2peak was 1.86+/-0.77 L min-1 (Z-score: -0.39+/-1.61) which was not significantly different from reference values. Relative VO2peak was 47.42+/-8.29 mL min-1 kg-1 (Z-score: -0.52+/-1.43), which did not differ significantly from reference values either. One boy suffered a joint bleeding one day after the test. Haemo-Qol scores in parents and children ranged from 3.2% to 36.7% (100% reflects poor outcome). Relationship between the child or parent reports of Haemo-QoL and both absolute and relative VO2peak ranged from R=0.00 and R=0.4. Exercise testing in children with severe haemophilia A was a safe procedure. Patients with severe haemophilia A with good joint health and no limitations of activities have comparable physical fitness and physical active lifestyle with healthy peers and good HRQoL.

Chronic fatigue syndrome and health control in adolescents and parents.

AIMS: To explore the locus of health control in adolescents with chronic fatigue syndrome (CFS) and their parents in comparison with healthy adolescents and their parents. METHODS: In this cross-sectional study 32 adolescents with CFS were compared with 167 healthy controls and their respective parents. The Multidimensional Health Locus of Control (MHLC) questionnaire was applied to all participants. RESULTS: There was significantly less internal health control in adolescents with CFS than in healthy controls. An increase of internal health control of one standard deviation was associated with a 61% reduced risk for CFS (OR = 0.39, 95% CI 0.25 to 0.61). Internal health control of the parents was also protective (OR fathers: 0.57 (95% CI 0.38 to 0.87); OR mothers: 0.74 (95% CI 0.50 to 1.09)). The external loci of health control were higher in adolescents with CFS and in their parents. Increased levels of fatigue (56%) were found in the mothers of the adolescents with CFS, in contrast with the fathers who reported a normal percentage of 13. CONCLUSIONS: In comparison with healthy adolescents, adolescents with CFS and their parents show less internal health control. They attribute their health more to external factors, such as chance and physicians. This outcome is of relevance for treatment strategies such as cognitive behaviour therapy, for which health behaviour is the main focus.

[Systematic review of the effects of therapy in infants with the KISS-syndrome (kinetic imbalance due to suboccipital strain)].

OBJECTIVE: To establish the effects of manual therapy, chiropractic, or osteopathic treatment of the KISS-syndrome (kinetic imbalance due to suboccipital strain) in infants with positional preference, plagiocephaly, and colic. DESIGN: Systematic review of the literature. METHOD: PubMed, Embase and the Cochrane Library were searched for articles on the effects of manual therapy, chiropractic and osteopathy on the KISS-syndrome. Experts in the field of manual medicine and osteopathy were asked to provide relevant articles. The bibliography in a textbook of manual therapy for children was hand-searched for additional references to the KISS-syndrome. RESULTS: No clinical trials were found that evaluated the effects of manual therapy or osteopathy on either the KISS-syndrome or its symptoms. Pooled analysis of two randomised clinical trials on the effects of chiropractic in infantile colic showed no statistically significant difference between active and control treatments. In addition, we found that 22% of infants showed short episodes of apnoea during manual therapy of the spine, and that one case has been described in which such apnoea resulted in death. CONCLUSION: Given the absence of evidence of beneficial effects of spinal manipulation in infants and in view of its potential risks, manual therapy, chiropractic and osteopathy should not be used in infants with the KISS-syndrome, except within the context of randomised double-blind controlled trials.

Thoracic excursion measurement in children with cystic fibrosis.

BACKGROUND: Measurement of thoracic excursion (TEM) during maximal ventilation is part of the physiotherapy assessment in children with cystic fibrosis (CF). OBJECTIVES: The purpose of our study was to examine the reliability of TEM and its relation with pulmonary function. METHODS: Thoracic excursions were measured using a measuring tape. Thirty children participated in an intra-observer and inter-observer reliability study. Reliability was determined by calculating the typical error in repeated measurement, limits of agreement and correlation coefficients. Cross-sectional data from the annual check-ups were used to measure the relation between TEM and pulmonary function. RESULTS: In the intra-observer reliability study the typical error was 0.31 cm, the limits of agreement were +/-0.86 cm. Pearson's r and ICC were 0.96 and 0.95, respectively. In the inter-observer reliability study these values were 0.56 cm, +/-1.55 cm, 0.85 and 0.85, respectively. TEM correlated significantly with height (0.31, P<0.001), FVC (0.44, P<0.001), FEV1 (0.41, P<0.001) and TLC (0.19, P<0.05), and there was a significant inverse correlation with RV%TLC (-0.45, P<0.001). CONCLUSIONS: TEM is a reliable assessment tool. Thoracic excursion is significantly, although moderately correlated with pulmonary function.

The relationship between generalized joint hypermobility and motor development.

PURPOSE: The aim of this study was to investigate the relationship between the presence and localization of joint hypermobility and delay in motor development. METHODS: A retrospective chart review was performed. All children younger than 2.5 years of age and between four and 12 years of age with generalized joint hypermobility were included. Generalized joint hypermobility was assessed using the criteria of Bulbena. In children between one and 2.5 years of age, motor development was measured using the Bayley Scales of Infant Development. In children four to 12 years of age, the Movement Assessment Battery for Children was used. RESULTS: Data from 72 children were available for analysis. In nine of 16 children younger than 2.5 years of age, a delay in motor development was found without a significant association between the delay in motor development (yes/no) and the Bulbena score (odds ratio: 0.4; 95% confidence interval: 0.07-2.1). In children between four and 12 years of age, a severe delay in motor development was present in 14 of 56 children (25%), while 12 of 56 children (21%) were at risk and 30 of 56 (54%) were age appropriate. No significant association between delay in motor development and the Bulbena score was found (odds ratio: 1.3; 95% confidence interval: 0.8-2.1). The age of independent walking was not significantly associated with the number of hypermobile joints (Bulbena score) (linear regression coefficient: 0.3; 95% confidence interval: -1.5 - 2.1). CONCLUSIONS: Although severe delays in motor development may be observed in approximately one third of children with generalized joint hypermobility, there is no association between the amount of generalized joint hypermobility and delay in motor development.

Is chronic fatigue syndrome a connective tissue disorder? A cross-sectional study in adolescents.

OBJECTIVES: To investigate whether constitutional laxity of the connective tissues is more frequently present in adolescents with chronic fatigue syndrome (CFS) than in healthy controls. Increased joint hypermobility in patients with CFS has been previously described, as has lower blood pressure in fatigued individuals, which raises the question of whether constitutional laxity is a possible biological predisposing factor for CFS. DESIGN: Cross-sectional study. PARTICIPANTS: Thirty-two adolescents with CFS (according to the criteria of the Centers for Disease Control and Prevention) referred to a tertiary hospital and 167 healthy controls. METHODS: The 32 adolescents with CFS were examined extensively regarding collagen-related parameters: joint mobility, blood pressure, arterial stiffness and arterial wall thickness, skin extensibility, and degradation products of collagen metabolism. Possible confounding factors (age, gender, height, weight, physical activity, muscle strength, diet, alcohol consumption, and cigarette smoking) were also measured. The results were compared with findings in 167 healthy adolescents who underwent the same examinations. RESULTS: Joint mobility, Beighton score, and collagen biochemistry, all indicators of connective tissue abnormality, were equal for both groups. Systolic blood pressure, however, was remarkably lower in patients with CFS (117.3 vs. 129.7 mm Hg; adjusted difference: -13.5 mm Hg; 95% confidence interval [CI]: -19.1, -7.0). Skin extensibility was higher in adolescents with CFS (mean z score: 0.5 vs. 0.1 SD; adjusted difference: 0.3 SD; 95% CI: 0.1, 0.5). Arterial stiffness, expressed as common carotid distension, was lower in adolescents with CFS, indicating stiffer arteries (670 vs 820 mum; adjusted difference: -110 mum; 95% CI: -220, -10). All analyses were adjusted for age, gender, body mass index, and physical activity. Additionally, arterial stiffness was adjusted for lumen diameter and pulse pressure. CONCLUSIONS: These findings do not consistently point in the same direction of an abnormality in connective tissue. Patients with CFS did have lower blood pressure and more extensible skin but lacked the most important parameter indicating constitutional laxity, ie, joint hypermobility. Moreover, the collagen metabolism measured by crosslinks and hydroxyproline in urine, mainly reflecting bone resorption, was not different. The unexpected finding of stiffer arteries in patients with CFS warrants additional investigation.

Osteogenesis imperfecta in childhood: effects of spondylodesis on functional ability, ambulation and perceived competence.

We studied the effects of spondylodesis on spinal curvature, functional outcome, level of ambulation and perceived competence in 11 children with osteogenesis imperfecta (OI). Mean age at surgical intervention was 13.1 years (SD 2.5 years) and follow-up amounted to 3.4 years (SD 2.3 years). Spinal curvature was measured according to Cobb. The level of ambulation was scored according to the modified criteria of Bleck. Functional abilities and the amount of parental assistance were scored using the Dutch version of the Pediatric Evaluation of Disability Inventory (PEDI). Perceived competence was measured using the Harter Self-Perception Profile for Children. The amount of fatigue, spinal pain and presence of subjective dyspnea were scored with a visual analog scale. The median progression per year before spondylodesis was 6.1 degrees (interquartile range 2.9 degrees -12.9 degrees ) and after the spondylodesis it was 5.0 degrees (interquartile range 1.6 degrees -11.0 degrees ). No significant progression or regression in the level of ambulation was found. Perceived competence improved slightly. In the total score of the perceived competence, a borderline significant increase was found ( P-value 0.068). We concluded that spinal fusion in children with OI does not materially influence functional ability and level of ambulation. Self-perceived competence seemed to improve after surgery. The amount of pain, fatigue and subjective dyspnea seemed to diminish after spinal surgery. Progression of scoliosis proceeded, as did development of spinal curvature at the junction of the spondylodesis. Therefore, oral or intravenous bisphosphonates before and after spinal surgery should be considered.

The interaction between Sillence type and BMD in osteogenesis imperfecta.

Clinical studies with bisphosphonates in children with osteogenesis imperfecta (OI) show an increase in BMD and a decrease in fracture rate. Bone strength in children with OI is not only influenced by changes in BMD but also by changes in collagen I structure of the organic bone matrix. Therefore, we studied the interaction between these two factors in a cross-sectional, single center study including 54 children. We assumed that vertebral deformities in OI represent an unbalance between load and bone strength. Body weight was considered to be a well quantifiable load on vertebral bodies. BMD served as a marker, representing the amount of bone tissue available for vertebral load bearing, and the Sillence classification, either type I or III/IV, as a marker representing the quality of the organic bone matrix. Independent associations were observed between the prevalence of vertebral deformities and (1) Sillence type (OR: 5.7, 95%Cl:1.2-26.8), (2) BMD (OR: 0.003, 95%Cl: 0-0.25) and (3) body weight (OR: 1.15, 95%Cl: 1.05-1.25). Regarding the anthropometrical differences among the different types of OI, the BMD/body weight ratio was introduced to evaluate the BMD in relation to body size. Prevalent vertebral deformities were associated with low BMD/body weight ratios (OR: 0.04, 95%Cl: 0.008-0.2) in OI type I, but no association was found in type III/IV. It was concluded that BMD and Sillence type have independent relationships with vertebral deformities. The BMD/body weight ratio correlates with vertebral deformities in children with OI type I. Its meaning in types III/IV needs further research with larger samples because of the relatively high prevalence of vertebral deformities in this group.

Osteogenesis imperfecta in childhood: MR imaging of basilar impression.

OBJECTIVE: To determine on radiographs the presence of Basilar Impression (BI) in children with Osteogenesis Imperfecta (OI). To confirm this sign and altered geometrical relationships of the craniocervical junction in course of time with magnetic resonance imaging (MRI). METHODS AND PATIENTS: In a cohort study of 130 patients with OI (OI type I: 85; OI type III: 21; OI type IV: 24) lateral radiographs of the skull and cervical spine were made in a standardised way. MRI scans were performed when BI was suspected based upon protrusion of the odontoid above Chamberlain's line. Intracranial abnormalities as well as the basal angle were described. Neurological examination was performed in patients with conclusive BI at MRI-scan. RESULTS AND DISCUSSION: In eight patients BI could be confirmed by MRI-scan. None of the children had or developed in time neurological symptoms or signs. Follow up of BI by MRI scans was done in seven patients (mean: 5 years; range: 2-6 years). No alteration of intracranial findings were seen at subsequent investigation, although in one child Chamberlain's line increased from 8 (first MRI) to 15 mm (last MRI). BI can be diagnosed by radiographs but in the extreme osteoporotic bone and altered anatomy of the craniocervical junction of children with OI MRI is preferable. As intracranial pathology can be demonstrated by MRI, also a relation can be laid to possible neurological symptoms and signs at clinical examination. CONCLUSION: In our cohort study no alteration of the intracranial contents was seen at subsequent MRI scans. Although anatomic deformations exist in BI, no neurological symptoms or signs were present in our study and no operative reconstruction had to be performed. Periodical MRI-scan has not been of influence on the clinical decision making process. At the moment we perform a MRI-scan if BI is suspected at lateral skull radiographs. The MRI images serve as reference findings to anticipate on possible future symptoms and signs of neurological deficit.

Torticollis and plagiocephaly in infancy: therapeutic strategies.

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.
