Cerebral palsy in Al-Quseir City, Egypt: prevalence, subtypes, and risk factors

Prevalence and Types of Strabismus in Cerebral Palsy: A Global and Historical Perspective Based on a Systematic Review and Meta-Analysis

PURPOSE

Strabismus is more frequent in cerebral palsy (CP) than in the normal population, but reports differ how much it is increased. We here examined the global prevalence and types of strabismus in CP, whether esotropia or exotropia is more frequent, and whether the prevalence differs between ethnicities and/or country income levels, and between generations.

METHODS

We compiled in a systematic review and meta-analysis the results of 147 CP studies that report the prevalence of strabismus or the ratio of esotropia to exotropia, and we conducted subgroup analyses for region (income level) and ethnicity. We performed a pooled analysis for the CP strabismus prevalence, and estimated the global number of CP cases with strabismus.

RESULTS

The pooled prevalence of strabismus in CP is 49.8% in high-income countries and 39.8% in lower-income countries. We estimate the global number of strabismus cases in CP as 12.2 million, with 7.6 million males and 4.6 million females, based on current estimates of 29.6 million global CP cases. Esotropia is more frequent than exotropia in Caucasians, while exotropia is more frequent than esotropia in Hispanic and in some Asian and African populations. The strabismus prevalence in CP increases with increasing country income levels.

CONCLUSION

Generational changes in strabismus prevalence appear to reflect a transition of CP types and an increase in prevalence as countries attain higher income and more effective maternal health care. The distribution of esotropia and exotropia in CP patients largely reflects the horizontal strabismus type that is predominant in the subject's ethnicity.

Estimating the Prevalence of Cerebral Palsy in a Semi-Urban City in Benin: A Door-to-Door Community-Based Study

INTRODUCTION

Cerebral palsy (CP) is the most common cause of pediatric motor disability. While epidemiological data are widespread in high-income countries, corresponding data in low-income countries in sub-Saharan Africa are still rare. This study aimed to estimate the prevalence of CP in Northern Benin, a French-speaking low-income country in sub-Saharan Africa.

METHODS

This study was a community-based door-to-door study involving children younger than 18 years old, in Parakou, a semi-urban city in Benin. We used a two-stage procedure. The first one consisted on children screening to identify potential cases of CP. During the second stage, suspected children were examined by neurologists with high experience with CP.

RESULTS

In total, 2,630 children were screened with 10 confirmed cases of CP, resulting in a crude prevalence (95% confidence interval) of 3.8 (1.4, 6.15) per 1,000 children. Of the 10 confirmed cases, six were younger than 5 years old, and five were male. Eight children over ten were spastic with six bilateral spastic subtype according to the Surveillance of Cerebral Palsy in Europe classification system. Seven children had a Gross Motor Function Classification System level III-V, and six were classified level III to V of the manual ability classification system.

CONCLUSION

CP is highly prevalent in semi-urban area in Northern Benin. Large studies on potential risk factors are needed for the development of effective preventive strategies.

Is the Walking Adaptability Ladder test for Kids (WAL-K) reliable and valid in ambulatory children with Cerebral Palsy?

PURPOSE

Walking adaptability is essential for children to participate in daily life. We studied whether the Walking Adaptability Ladder test for Kids (WAL-K) is reliable and valid for assessing walking adaptability in 6-12 year old ambulatory children with Cerebral Palsy (CP).

MATERIALS AND METHODS

Thirty-six children with CP (26 GMFCS-level I, 10 GMFCS-level II) completed the single and double run of the WAL-K. Intra- and inter-rater reliability were determined by Intraclass Correlation Coefficients (ICCs). Construct validity was determined by comparing WAL-K scores between 122 typically developing (TD) and CP children taking age into account, comparing WAL-K scores between CP children in GMFCS-levels I and II, and correlating WAL-K scores with scores of the 10 times 5 m Sprint Test (10 × 5mST).

RESULTS

ICCs for reliability varied between 0.997 and 1.000. WAL-K scores were significantly higher (i.e., worse) in CP children compared to TD children (p < 0.001), and in children in GMFCS-level II compared to GMFCS-level I (p = 0.001). Significant positive correlations were found between the WAL-K and 10 × 5 mST (single run r = .89, double run r = .84).

CONCLUSIONS

The WAL-K shows to be a promising reliable, valid, and easy-to-use tool for assessing walking adaptability in children with CP. Responsiveness to change has yet to be evaluated.

Prevalence and types of strabismus in cerebral palsy: A global and historical perspective based on a systematic review and meta-analysis

Purpose

Strabismus is more frequent in cerebral palsy (CP) than in the normal population, but reports differ how much it is increased. We here examined the global prevalence and types of strabismus in CP, whether esotropia or exotropia is more frequent, and whether the prevalence differs between ethnicities and/or country income levels, and between generations.

Methods

We compiled in a systematic review and meta-analysis the results of 147 CP studies that report the prevalence of strabismus or the ratio of esotropia to exotropia, and we conducted subgroup analyses for region (income level) and ethnicity. We performed a pooled analysis for the CP strabismus prevalence, and estimated the global number of CP cases with strabismus.

Results

The pooled prevalence of strabismus in CP is 49.8% in high-income countries and 39.8% in lower-income countries. We estimate the global number of strabismus cases in CP as 12.2 million, with 7.6 million males and 4.6 million females, based on current estimates of 29.6 million global CP cases. Esotropia is more frequent than exotropia in Caucasians, while exotropia is more frequent than esotropia in Hispanic and in some Asian and African populations. The strabismus prevalence in CP increases with increasing country income levels.

Conclusion

Generational changes in strabismus prevalence appear to reflect a transition of CP types and an increase in prevalence as countries attain higher income and more effective maternal health care. The distribution of esotropia and exotropia in CP patients largely reflects the horizontal strabismus type that is predominant in the subject's ethnicity.

Risk Factors for Mortality in Patients With Cerebral Palsy: A Systematic Review and Meta-Analysis

Cerebral palsy (CP) is a developmental and physical disorder with different degrees of severity. Since CP manifests itself in early childhood, numerous research studies have concentrated on children with CP. Patients with CP encounter different severity of motor impairments attributed to the damage or disturbance to the fetal or infant developing brain, which begins in early childhood and persists through adulthood. Patients with CP are more prone to mortality compared to the general population. This systematic review and meta-analysis aimed to assess the risk factors that predict and influence mortality in patients with CP. Systematic search for studies assessing the risk factors for mortality in CP patients that were conducted from 2000 to 2023 in Google Scholar, PubMed, and Cochrane Library was performed. R-One Group Proportion was used for statistical analysis and Newcastle-Ottawa Quality Assessment Scale (NOS) for quality appraisal. Of the 1791 total database searches, nine studies were included. Based on the NOS tool for quality appraisal, seven studies were of moderate quality, and two studies were rated as of high quality. The risk factors included pneumonia and other respiratory infections, neurological disorders, circulatory diseases, gastrointestinal infections, and accidents. Pneumonia (OR = 0.40, 95% CI = 0.31 - 0.51), neurological disorders (OR = 0.11, 95% CI = 0.08 - 0.16), respiratory infections (OR = 0.36, 95% CI = 0.31 - 0.51), cardiovascular and circulatory diseases (OR = 0.11, 95% CI = 0.04 - 0.27), gastrointestinal and metabolic causes (OR = 0.12, 95% CI = 0.06 - 0.22), and accidents (OR = 0.05, 95% CI = 0.04 - 0.07) were the risk factors assessed. It was concluded that multiple factors predict the risk of mortality in patients with CP. Pneumonia and other respiratory infections are associated with a high risk of mortality. Cardiovascular and circulatory diseases, gastrointestinal and metabolic disorders, and accidents are strongly linked to mortality in CP patients.

Attitude of Parents of Children with Cerebral Palsy Towards COVID-19 Vaccination

Children with cerebral palsy (CP) are at a greater risk of respiratory complications from coronavirus disease 2019 (COVID-19). Therefore, this study aimed to assess COVID-19 vaccine hesitancy (VH) among parents of CP children in Egypt, using the Arabic version of the Parental Attitude about Childhood Vaccination (PACV) questionnaire. This cross-sectional survey study was conducted at the outpatient clinics of two hospitals in Cairo, Egypt. Parents of children with CP were recruited using a simple random sampling technique. A total of 321 parents were enrolled; more than half of them were mothers of the children (61.37%); and the majority were Egyptians (87.23%) and living in urban areas (84.42%). Nearly 70% of the parents were hesitant to administer the COVID-19 vaccine to their children. A multiple linear regression model revealed that the PACV mean scores were lower among the following categories: (1) parents who could pay back loans, compared to those who could not pay back loans and who reported insufficient income (β = -2.39, p = 0.030); (2) non-Egyptian parents (β = -1.54, p = 0.002); (3) those who were fully vaccinated against COVID-19 themselves or had the intention to receive the complete COVID-19 vaccination (β = -6.28, p < 0.001); (4) those who had the intention to give the COVID-19 vaccination to their children (β = -3.04, p < 0.001); and (5) parents whose children received routine vaccines (β = -2.86, p < 0.045). After adjusting for other covariates, the parental COVID-19 vaccine status (β = -6.28, p < 0.001) and parents who experienced a COVID-19-related death in the family (β = -1.75, p < 0.001) showed significantly lower mean PACV scores. However, higher mean PACV scores were reported among parents who had a COVID-19 infection (β = 2.77, p < 0.001) or who were not sure (β = 2.94, p < 0.001). Our findings suggest the need to increase COVID-19 vaccine acceptance among parents of vulnerable children to reduce the negative consequences of COVID-19.

Characterization of Infants' General Movements Using a Commercial RGB-Depth Sensor and a Deep Neural Network Tracking Processing Tool: An Exploratory Study

Cerebral palsy, the most common childhood neuromotor disorder, is often diagnosed through visual assessment of general movements (GM) in infancy. This skill requires extensive training and is thus difficult to implement on a large scale. Automated analysis of GM performed using low-cost instrumentation in the home may be used to estimate quantitative metrics predictive of movement disorders. This study explored if infants' GM may be successfully evaluated in a familiar environment by processing the 3D trajectories of points of interest (PoI) obtained from recordings of a single commercial RGB-D sensor. The RGB videos were processed using an open-source markerless motion tracking method which allowed the estimation of the 2D trajectories of the selected PoI and a purposely developed method which allowed the reconstruction of their 3D trajectories making use of the data recorded with the depth sensor. Eight infants' GM were recorded in the home at 3, 4, and 5 months of age. Eight GM metrics proposed in the literature in addition to a novel metric were estimated from the PoI trajectories at each timepoint. A pediatric neurologist and physiatrist provided an overall clinical evaluation from infants' video. Subsequently, a comparison between metrics and clinical evaluation was performed. The results demonstrated that GM metrics may be meaningfully estimated and potentially used for early identification of movement disorders.

Epidemiology of Cerebral Palsy among Children and Adolescents in Arabic-Speaking Countries: A Systematic Review and Meta-Analysis

Background: Studies on cerebral palsy among children and adolescents in Arabic-speaking countries are scarce. In this systematic review, we aimed to describe the epidemiology of cerebral palsy among children and adolescents in Arabic-speaking countries in terms of prevalence, risk factors, motor types, and rehabilitation. Methods: Six key bibliographic databases were searched for relevant literature published to 17 July 2021. Titles and abstracts were screened for potential inclusion and two independent reviewers screened the full texts of potential articles following pre-defined inclusion/exclusion criteria. The included studies were evaluated independently by three reviewers. The risk of bias was assessed, and data were extracted and analysed. Results: A total of 32 studies from 7 countries met our inclusion criteria. The prevalence of cerebral palsy in Arabic-speaking countries was 1.8/1000 live births (95% CI: 1.2–2.5). Spastic cerebral palsy was the most common motor type, representing 59.8% (95% CI: 46.2–72.7) of pooled estimates. This included children with spastic quadriplegia, diplegia, and hemiplegia; 25.1% (95% CI: 18.2–32.8), 16.2% (95% CI: 11.4–23.3), and 10.4% (95% CI: 7.3–13.8), respectively. Consanguinity was high and represented 37.7% (95% CI: 29.3–46.6). Only one included study reported the types of rehabilitation received (e.g., physiotherapy and assistance devices). Conclusions: This paper provides a summary of the epidemiology of cerebral palsy in Arabic-speaking countries and highlights areas for future research. There is still a substantial knowledge gap on the epidemiology of cerebral palsy in these regions. Countries in the Arab region should follow examples of countries that have successfully established cerebral palsy registries to generate evidence on epidemiology of cerebral palsy and opportunities for prevention.

Prevalence of the need for adaptive seating systems among children with cerebral palsy in Egypt

BACKGROUND

An adaptive seating system is a basic rehabilitation need for children and youth with cerebral palsy (CP) as it supports the structure and function of the musculoskeletal system and can positively affect their activities and participation. Despite the importance of adaptive seating systems, there is limited access to such systems in low-income countries.

OBJECTIVES

To determine the percentage of children and youth between 4 and 18 years of age with CP in Egypt whose activity level and sitting ability suggest the need for an adaptive seating system.

STUDY DESIGN

Observational cross-sectional study.

METHODS

One hundred ninety-three participants were included after fulfilling the criteria of the Surveillance of Cerebral Palsy of Europe. Their level of activity was assessed by a physical therapist using the Gross Motor Function Classification System (GMFCS), and their sitting ability was evaluated using the Level of Sitting Scale (LSS). Participants were considered to require an adaptive seating system if they scored GMFCS level IV or V and LSS level 1-5 concurrently.

RESULTS

Approximately 44% of the study participants were classified as GMFCS level IV or V and LSS level 1-5, suggesting that they were in need of an adaptive seating system.

CONCLUSIONS

There is a large percentage of children and youth with CP in Egypt who need an adaptive seating system to be integrated into their rehabilitation.

Akwenda intervention programme for children and youth with cerebral palsy in a low-resource setting in sub-Saharan Africa: protocol for a quasi-randomised controlled study

INTRODUCTION

Cerebral palsy (CP) is the most common childhood-onset motor disorder accompanied by associated impairments, placing a heavy burden on families and health systems. Most children with CP live in low/middle-income countries with little access to rehabilitation services. This study will evaluate the Akwenda CP programme, a multidimensional intervention designed for low-resource settings and aiming at improving: (1) participation, motor function and daily activities for children with CP; (2) quality of life, stress and knowledge for caregivers; and (3) knowledge and attitudes towards children with CP in the communities.

METHODS

This quasi-randomised controlled clinical study will recruit children and youth with CP aged 2-23 years in a rural area of Uganda. Children will be allocated to one of two groups with at least 44 children in each group. Groups will be matched for age, sex and motor impairment. The intervention arm will receive a comprehensive, multidimensional programme over a period of 11 months comprising (1) caregiver-led training workshops, (2) therapist-led practical group sessions, (3) provision of technical assistive devices, (4) goal-directed training and (5) community communication and advocacy. The other group will receive usual care. The outcome of the intervention will be assessed before and after the intervention and will be measured at three levels: (1) child, (2) caregiver and (3) community. Standard analysis methods for randomised controlled trial will be used to compare groups. Retention of effects will be examined at 12-month follow-up.

ETHICS AND DISSEMINATION

The study has been approved by the Uganda National Council for Science and Technology (SS 5173) and registered in accordance with WHO and ICMJE standards. Written informed consent will be obtained from caregivers. Results will be disseminated among participants and stakeholders through public engagement events, scientific reports and conference presentations.

Efficacy of oral magnesium therapy in the treatment of chronic constipation in spastic cerebral palsy children: a randomized controlled trial

BACKGROUND

Constipation is a common problem in children with spastic cerebral palsy (sCP) with a prevalence that reaches 75%. We hypothesized that treating constipation in those children will improve their health and shorten time spent in daily care. Our aim was to evaluate the efficacy and safety of oral magnesium sulfate for treating chronic constipation in children with sCP.

METHODS

A prospective, double-blinded randomized control trial was carried out involving 100 children aged 2-12 years with sCP (level III-V of the Gross Motor Functional Classification system) and chronic constipation. They were followed up in the Pediatric neurology clinic, Children's hospital, Ain Shams University, May 2017- January 2019. The intervention group (O-Mg) received oral magnesium sulfate 1 mL/kg/day daily for 1 month compared to the placebo. Outcome measures were constipation improvement and decrease in bowel evacuation time after 1 month.

RESULTS

Initially, weekly bowel movements, constipation scores and stool consistency were comparable in both groups. After 1 month of regular administration of oral magnesium sulfate, the constipation score, stool frequency and consistency improved compared to the placebo group (P < 0.001). Effective safe treatment was achieved in 31 (68%) and 4 (9.5%) patients in the O-Mg and placebo groups, respectively (RR, 2.95; 95% CI 2.0-4.5) (P < 0.001). Painful bowel evacuation attempts spent by mothers decreased from 25 (55.6%) of the cases initially to 10 (22%) cases after one month in the O-Mg group (P = 0.001). In contrast, in the placebo group, the decrease went from 21 (50%) cases initially to 18 (42.9%) after 1 month and was not significant (P = 0.5).

CONCLUSIONS

Oral magnesium sulfate seems effective in alleviating chronic constipation and pain experience in children with sCP. Consequently, saving maternal time spent in daily bowel evacuation attempts.

Prevalence of cerebral palsy with Gross Motor Function Classification System levels IV and V in children in Israel: a cross-cultural comparison

PURPOSE

Cerebral palsy is the most common physical disability in childhood. Our aim was to study the prevalence of wheelchair-dependent cerebral palsy (equivalent to gross motor function classification system level IV/V) among Jewish and Arab children in Israel and to investigate differences between the children of the two population groups.

METHODS

Children diagnosed with cerebral palsy born in the years 2005-2006 were located through the Israel National Insurance Institute database. Demographic and clinical data were retrieved from children's records.

RESULTS

Overall prevalence in Israel was 0.8 (0.7-0.9) per 1000 live births. The prevalence was significantly higher among Arabs (1.2:1000) than Jews (0.6:1000; OR = 1.6, 95% CI 1.2-2.1, p = 0.001) and was highest among Arabs in the South (Bedouins) (2.8:1000). Consanguinity among parents and low socioeconomic status were significantly more common among Arab children with wheelchair- dependent cerebral palsy compared with Jews. Higher rates of children with cerebral palsy following term pregnancy were found in Arabs. Extreme preterm births, very low birth weight, and emergent cesarean section were more common among Jews compared with Arabs.

CONCLUSIONS

This study revealed population group differences of cerebral palsy with Gross Motor Function Classification System levels IV and V. Higher rates of cerebral palsy, especially following term pregnancy in the Arab population, may be attributed to consanguinity and genetic factors. There is a need to tailor services to underserved population based on etiology: preterm births and genetic causes for the Jewish and Arab populations, respectively.

Knowledge of Neonatal Hyperbilirubinemia Among Primary Health Care Physicians: A Single-Center Experience

Background and objectives:

To evaluate the knowledge of the primary health care physicians (PHCP) in Kalubia governorate, Egypt, about the causes, diagnosis, complications, and treatment of neonatal hyperbilirubinemia (NHB).

Methods:

Cross-sectional survey distributed by interview to 500 physicians working in the primary health care (PHC) sector in Kalubia.

Results:

Out of 500 distributed surveys, 419 (84%) PHCP completed the questionnaire. They represent 174 (90%) out of 193 PHC units and centers. About 18% were males and 82% females with mean age of 28.5 ± 5.2 years, and mean duration of work was 3.3 ± 4.4 years. All of the respondents have patients with NHB in their daily practice. The knowledge of the PHCP was good in some aspects about NHB; however, it was poor and may be even hazardous in other aspects.

Conclusions:

Many areas of defects are detected in PHCP knowledge about NHB. Pre-service and continuous training of the PHCP about the diagnosis and management of NHB are essential.

Caries experience and oral health-related quality of life (OHRQoL) of children and adolescents with cerebral palsy in a low-resource setting

Background

Children with complex neurodevelopmental disabilities such as cerebral palsy (CP), have a higher risk of dental disease related at least in part to greater difficulties in performing and maintaining effective oral hygiene and oral care practices. However, to date, there are very few studies that have considered the impact of dental disease on the Oral Health-Related Quality of Life (OHRQoL) of children and adolescents with cerebral palsy. This study aimed to investigate the association between dental caries experience and oral health related quality of life (OHRQoL) among children and adolescents with cerebral palsy in a low-resource setting (Bangladesh).

Methods

A total of 90 children and adolescents with CP, 2–17 years old (median age 10 years; 37.8% female and 62.2% male) were randomly selected from the Bangladesh Cerebral Palsy Register (BCPR) The decayed, missing and filled teeth (dmft/DMFT) index was used to measure caries experience. Child Perceptions Questionnaire (CPQ) and Family Impact Scale (FIS) were used to assess oral health–related quality of life (OHRQoL). Binary logistic regression was used to investigate factors that may contribute to dental caries experience.

Results

Dental caries were observed among 55.6% of the participants. After adjusting for age and gender, binary logistic regression analysis showed that dental caries experience was significantly associated with those who had teeth/mouth pain (rate ratio 7.3; P = 0.02), food caught between teeth (rate ratio: 6.4; P = 0.02), difficulty in eating and drinking (rate ratio 5.9; p = 0.02) and those who felt frequently upset (rate ratio: 54.7; P = 0.02).

Conclusion

In this study, we found that children and adolescents with CP in a low-resource setting had high dental caries experience and that dental caries had a negative impact on OHRQoL amongst these participants and their parents/caregivers. Health care professionals should be aware of the importance of dental health and oral hygiene in this population. These findings highlight the need for oral health promotion programs for children and adolescents with CP in these settings to reduce pain and to improve quality of life.

National Registry Data from Korean Neonatal Network: Two-Year Outcomes of Korean Very Low Birth Weight Infants Born in 2013-2014

BACKGROUND

The aim of this study was to observe long-term outcomes of very low birth weight infants (VLBWIs) born between 2013 and 2014 in Korea, especially focusing on neurodevelopmental outcomes.

METHODS

The data were collected from Korean Neonatal Network (KNN) registry from 43 and 54 participating units in 2013 and 2014, respectively. A standardized electronic case report form containing 30 items related to long-term follow up was used after data validation.

RESULTS

Of 2,660 VLBWI, the mean gestational age and birth weight were 29^1/7 ± 2^6/7 weeks and 1,093 ± 268 g in 2013 and 29^2/7 ± 2^6/7 weeks and 1,125 ± 261 g in 2014, respectively. The post-discharge mortality rate was 1.2%-1.5%. Weight < 50th percentile was 46.5% in 2013 and 66.1% in 2014. The overall prevalence of cerebral palsy among the follow up infants was 6.2% in 2013 and 6.6% in 2014. The Bayley Scales of Infant Developmental Outcomes version II showed 14%-25% of infants had developmental delay and 3%-8% of infants in Bayley version III. For the Korean developmental screening test for infants and children, the area "Further evaluation needed" was 5%-12%. Blindness in both eyes was reported to be 0.2%-0.3%. For hearing impairment, 0.8%-1.9% showed bilateral hearing loss. Almost 50% were readmitted to hospital with respiratory illness as a leading cause.

CONCLUSION

The overall prevalence of long-term outcomes was not largely different among the VLBWI born between 2013 and 2014. This study is the first large national data study of long-term outcomes.

Cerebral palsy in Moldova: subtypes, severity and associated impairments

BACKGROUND

Moldova is ranked as one of the countries in Europe with the lowest income per capita and with a relatively high infant and maternal mortality rate. Information on neurodisabilities in general is limited, and regarding cerebral palsy (CP) in particular, it is completely lacking. The aim of this study was therefore to make a crude estimate of the prevalence of CP and to describe subtypes and the severity of motor impairments and associated problems in this country.

METHODS

Children with CP born 2009-2010, attending the National Hospital Institute of Mother and Child, the reference hospital for ~ 75% of children in Moldova with neurological disabilities, were identified from medical records.

RESULTS

Among 207 children with CP (estimated prevalence 3.4 per 1000 live births), 185 (mean age 7.3 years; 36% girls) had detailed information. Thirty seven (20%) children had spastic unilateral, 113 (61%) spastic bilateral, 22 (12%) dyskinetic and 9 (5%) children had ataxic CP. The subtype was unclassified in four children. Among all children, 93 (51%) had epilepsy, 109 (59%) intellectual disability, 42 (23%) severe vision and 10 (5%) hearing impairments while 84 (45%) children had severe speech impairments. Fifty-two (28%) children were born prematurely, and 46 (25%) had Apgar scores below 7 at five minutes.

CONCLUSION

Compared to other European studies, the distribution of CP subtypes was different in Moldova. Moreover, the estimated prevalence, the proportions with severe motor and associated impairments and of children born at term were higher in Moldova while the proportion with low Apgar did not differ. The findings may suggest different etiological pathways causing CP in Moldova than in other European countries. A national register is warranted for quality assurance and improvement.

Association between socioeconomic status and cerebral palsy

Background

The present study investigated the annual prevalence of cerebral palsy (CP) among children aged <7 years in Taiwan and the association between socioeconomic status and CP prevalence.

Methods

Data from the Taiwan National Health Insurance Research Database for the 2002−2008 period were used in this population-based study. Severe and total CP were defined according to catastrophic illness certificate and medical claim records, respectively. The annual CP prevalence was calculated as the number of children with CP among all children aged <7 years.

Results

From 2002 to 2008, the annual prevalence of total and severe CP ranged from 1.9 to 2.8 and from 1.1 to 1.4 per 1000 children, respectively. Boys were 30% more likely to have CP than girls [adjusted relative risk (RR) and 95% confidence interval (CI) ranged from 1.3 (1.2−1.4) to 1.4 (1.2−1.5)]. Low family income was associated with a higher CP prevalence [adjusted RR (95% CI) ranged from 5.1 (4.2−6.2) to 6.4 (5.4−7.6)]. The prevalence of CP in rural area was higher than that in urban or suburban areas. The mortality rate of severe CP ranged from 12.2−22.7 per 1000 children within the 7 years study period.

Conclusions

The prevalence of CP in Taiwan is similar to that in Western countries. A higher prevalence of CP is associated with male sex, low income, and rural residential location. Our findings provide insights into CP epidemiology among the Chinese population.

Clinical Spectrum of Cerebral Palsy and Associated Disability in South Egypt: A Local Survey Study

BACKGROUND

Cerebral palsy is the most common cause of motor disability in children with a prevalence of 2-10/1,000 live births in the developing areas.

AIM

The epidemiology, clinical picture, and associated comorbidities in CP have been extensively studied in high-resource countries, but in low-resource areas, including Africa, those studies are still lacking.

METHODS

Cerebral palsy cases were prospectively recruited from every physiotherapy centre in Bani-Mazar city, Egypt, in a cross-sectional study from May 2015 to November 2015.

RESULTS

Two hundred cases were enrolled with a prevalence of 1 per 1000 live births. Within the study population, 72.5% were the spastic type, 16% were dyskinetic, 7% were ataxic, and 4.5% were hypotonic. The most common comorbidities were cognitive impairment and epilepsy affecting 77% and 38%, respectively.

CONCLUSION

Cerebral palsy in developing countries has a higher prevalence and different clinical profile regarding severity and associated disability. The perinatal and high-quality neonatal care together with physical therapy and rehabilitation programs is still lacking in developing countries.

An international survey of cerebral palsy registers and surveillance systems

AIM

To describe cerebral palsy (CP) surveillance programmes and identify similarities and differences in governance and funding, aims and scope, definition, inclusion/exclusion criteria, ascertainment and data collection, to enhance the potential for research collaboration.

METHOD

Representatives from 38 CP surveillance programmes were invited to participate in an online survey and submit their data collection forms. Descriptive statistics were used to summarize information submitted.

RESULTS

Twenty-seven surveillance programmes participated (25 functioning registers, two closed owing to lack of funding). Their aims spanned five domains: resource for CP research, surveillance, aetiology/prevention, service planning, and information provision (in descending order of frequency). Published definitions guided decision making for the definition of CP and case eligibility for most programmes. Consent, case identification, and data collection methods varied widely. Ten key data items were collected by all programmes and a further seven by at least 80% of programmes. All programmes reported an interest in research collaboration.

INTERPRETATION

Despite variability in methodologies, similarities exist across programmes in terms of their aims, definitions, and data collected. These findings will facilitate harmonization of data and collaborative research efforts, which are so necessary on account of the heterogeneity and relatively low prevalence of CP.

Safety of Allogeneic Umbilical Cord Blood Stem Cells Therapy in Patients with Severe Cerebral Palsy: A Retrospective Study

This retrospective study aimed to assess the safety of patients with severe cerebral palsy (CP), who received allogeneic umbilical cord blood stem cells (UCBSCs) treatment from August 2009 to December 2012 in Guangdong Provincial Hospital of Chinese Medicine. A total of 47 patients with average age of 5.85 ± 6.12 years were evaluated in this study. There was no significant association with allogeneic UCBSCs treatments found in the data of the laboratory index . No casualties occurred. Some adverse events during treatments were found in 26 (55.3%) patients, including fever (42.6%) and vomiting (21.2%). Intrathecal infusion and the ages at the initiation of treatment (≤10 years old) were risk factors for the occurrence of adverse events by logistic regression analysis. However, all adverse events disappeared after symptomatic treatment. No treatment related serious adverse events were found in follow-up visits within 6 months. In conclusion, allogeneic UCBSCs treatment was relatively safe for severe CP patients.
