Social outcomes of young adults with cerebral palsy.

BACKGROUND: Functional abilities and social outcomes of young adults with cerebral palsy (CP) are relatively under-researched. Improvements in paediatric care have extended the expectation of achieving adulthood to 90%. METHOD: Young adults aged 20-30 years with CP (n = 335) were compared to a population-based control group (n = 2,152) of the same age. Motor function, self-care abilities, educational level, and social outcomes were determined by questionnaire. RESULTS: Half the study group walked independently, but only 35.5% were independent in self-care. In comparison to their peers without disability, the study group's highest educational level was lower (p < .0001), as were rates of employment (36.3% compared with 80%), they were more likely to be living with parents (80% compared with 21%), to be single, and to have limited financial resources. CONCLUSION: Young adults with CP are functionally and socially disadvantaged in contrast with their peers without disability. Self-care dependence, intellectual disability, and communication impairments contribute to these outcomes but are not solely responsible.

Magnetic resonance imaging findings in a population-based cohort of children with cerebral palsy.

The purpose of this study was to investigate the frequency and spectrum of magnetic resonance imaging (MRI) abnormalities in a population of children with cerebral palsy (CP) who were born in the years 2000 and 2001 in Victoria, Australia. In 2000 and 2001, 221 children (126 males, 95 females; mean age 6y [SD 7mo], range 5-7y) with CP, excluding those with CP due to postneonatal causes (6% of all cases), were identified through the Victorian Cerebral Palsy Register. All medical records were systematically reviewed and all available brain imaging was comprehensively evaluated by a single senior MRI radiologist. MRI was available for 154 (70%) individuals and abnormalities were identified in 129 (84%). The study group comprised 88% with a spastic motor type CP; the distribution was hemiplegia in 33.5%, diplegia in 28.5%, and quadriplegia in 37.6% of children. Overall, pathological findings were most likely to be identified in children with spastic hemiplegia (92%) and spastic quadriplegia (84%). Abnormalities were less likely to be identified in non-spastic motor types (72%) and spastic diplegia (52%). The most common abnormalities identified on MRI were periventricular white matter injury (31%), focal ischaemic/haemorrhagic lesions (16%), diffuse encephalopathy (14%), and brain malformations (12%). Dual findings were seen in 3% of patients. This is the first study to document comprehensively the neuroimaging findings of all children identified with CP born over a consecutive 24-month period in a large geographical area.

Post-neonatally acquired cerebral palsy in Victoria, Australia, 1970-1999.

AIM: To use the information from a population-based cerebral palsy register to describe post-neonatally acquired cerebral palsy, to determine trends over time and relate any aetiological trends to community preventative measures. METHODS: Data on cases of post-neonatally acquired cerebral palsy, between the birth years 1970 and 1999, were generated from the Victorian Cerebral Palsy Register. Distributions, rates and trends over time were calculated for the entire cohort and for subgroups according to gender, age at acquisition, aetiology, gestation at delivery, birthweight, maternal age at delivery and parity. RESULTS: 339 cases were found with post-neonatally acquired cerebral palsy, accounting for 10.7% of all cerebral palsy and giving an overall rate of 1.98/10 000 live births. There was a statistically significant fall in the overall rate of post-neonatally acquired cerebral palsy (P = 0.001) over the study period. Significant falls were seen in post-neonatal cerebral palsy due to infection, traumatic head injury and hypoxia and other acute encephalopathies, but not cerebrovascular accidents. CONCLUSION: A large proportion of post-neonatally acquired cerebral palsy is preventable. While the reported decline in cases in Victoria is encouraging, it will be important to monitor these trends over time, and continue public health measures to further reduce preventable causes.

Hip displacement in cerebral palsy.

BACKGROUND: Hip displacement is considered to be common in children with cerebral palsy but the reported incidence and the proposed risk factors vary widely. Knowledge regarding its overall incidence and associated risk factors can facilitate treatment of these children. METHODS: An inception cohort was generated from the Victorian Cerebral Palsy Register for the birth years 1990 through 1992, inclusive, and multiple data sources pertaining to the cohort were reviewed during 2004. Gross motor function was assessed for each child and was graded according to the Gross Motor Function Classification System (GMFCS), which is a valid, reliable, five-level ordinal grading system. Hip displacement, defined as a migration percentage of >30%, was measured on an anteroposterior radiograph of the pelvis with use of a reliable technique. RESULTS: A full data set was obtained for 323 (86%) of 374 children in the Register for the birth years 1990 through 1992. The mean duration of follow-up was eleven years and eight months. The incidence of hip displacement for the entire birth cohort was 35%, and it showed a linear relationship with the level of gross motor function. The incidence of hip displacement was 0% for children with GMFCS level I and 90% for those with GMFCS level V. Compared with children with GMFCS level II, those with levels III, IV, and V had significantly higher relative risks of hip displacement (2.7, 4.6, and 5.9, respectively). CONCLUSIONS: Hip displacement is common in children with cerebral palsy, with an overall incidence of 35% found in this study. The risk of hip displacement is directly related to gross motor function as graded with the Gross Motor Function Classification System. This information may be important when assessing the risk of hip displacement for an individual child who has cerebral palsy, for counseling parents, and in the design of screening programs and resource allocation.

Cerebral palsy in Victoria: motor types, topography and gross motor function.

OBJECTIVES: To study the relationships between motor type, topographical distribution and gross motor function in a large, population-based cohort of children with cerebral palsy (CP), from the State of Victoria, and compare this cohort to similar cohorts from other countries. METHODS: An inception cohort was generated from the Victorian Cerebral Palsy Register (VCPR) for the birth years 1990-1992. Demographic information, motor types and topographical distribution were obtained from the register and supplemented by grading gross motor function according to the Gross Motor Function Classification System (GMFCS). RESULTS: Complete data were obtained on 323 (86%) of 374 children in the cohort. Gross motor function varied from GMFCS level I (35%) to GMFCS level V (18%) and was similar in distribution to a contemporaneous Swedish cohort. There was a fairly even distribution across the topographical distributions of hemiplegia (35%), diplegia (28%) and quadriplegia (37%) with a large majority of young people having the spastic motor type (86%). CONCLUSIONS: The VCPR is ideal for population-based studies of gross motor function in children with CP. Gross motor function is similar in populations of children with CP in developed countries but the comparison of motor types and topographical distribution is difficult because of lack of consensus with classification systems. Use of the GMFCS provides a valid and reproducible method for clinicians to describe gross motor function in children with CP using a universal language.

Impact of disease severity on quality of life in adults with asthma.

Health-related quality of life is increasingly used as an outcome measure in asthma. The aim of this study was to define the relationship between asthma symptoms, lung function and health related quality of life in a community based sample of people with asthma ranging from no recent asthma to severe persistent asthma. We recruited subjects at the age of 42 years from a well-described community cohort, the Melbourne Epidemiological Study of Childhood Asthma, to define this association. 161 subjects completed a respiratory symptom survey, the Asthma Quality of Life Questionnaire and had lung function testing. According to the previous surveys and when applicable in agreement with GINA, subjects were classified into 4 groups: no recent asthma, sporadic asthma, intermittent asthma and persistent asthma, with the persistent asthma group further categorised by wheezing frequency and lung function. 55 had no recent asthma, 31 had sporadic asthma, 39 had intermittent asthma and 36 had persistent asthma. There was clear evidence of lower total scores with increased asthma severity, with median scores of 6.8 for the sporadic asthma group, 6.4 for the intermittent and 5.5 for the persistent asthma group compared to 6.9 in those with no recent asthma. All domain scores within the intermittent and persistent asthma groups were lower than scores for the no recent asthma group (p < 0.01). Those with persistent asthma and low FEV1% had the lowest quality of life scores (4.6). Analysis of this population cohort highlights that health related quality of life in patients with asthma strongly depends on symptom frequency and lung function and underlines the necessity of adequate treatment.
