Growth of severely impaired children: neurological versus nutritional factors

The Effects of Swallowing Disorders and Oral Malformations on Nutritional Status in Children with Cerebral Palsy

Nutrition plays an important role both from a nutrition and a socio-psychological point of view; this part seems to be even more crucial in cerebral palsy where undernutrition is responsible for an increase in morbidity and mortality. The objective of this study was to evaluate the effects of swallowing disorders and oral malformations on the nutritional status of children with cerebral palsy. We evaluated 65 patients aged 2 to 17 years using a cross-sectional, descriptive and observational approach. All patients had a definite diagnosis of cerebral palsy. The measurement of anthropometric variables (weight, height, Body Mass Index (BMI) and circumferences) was performed according to recognized techniques and measurements. The Z-score was also calculated using the World Health Organization (WHO) references. The 5-level Gross Motor Function Classification System was used, providing a standardized classification of motor disability patterns for children with cerebral palsy. The population had a median age of 9.25 (4.50−16.00) and was about 53% female. Furthermore, 75% of the patients had a height inferior to 158 cm. The results of our study show that 42 (64.6%) had false routes, 17 (26.2%) had oral-facial malformations and 51 (78.5%) did not have lip prehensions during meals. The results also show that growth retardation is closely related to gross motor function with p = 0.01, as well as all nutritional indices (Z-score weight for age, Z-score height for age and Z-score BMI for age) are affected by swallowing disorders and oral malformations, with statistically significant values < 0.05. In conclusion, a preventive and curative management specific to this population of children with cerebral palsy must be implemented with an interdisciplinary concertation.

Glycine receptor subunit-ß -deficiency in a mouse model of spasticity results in attenuated physical performance, growth and muscle strength

Spasticity is the most common neurological disorder associated with increased muscle contraction causing impaired movement and gait. The aim of this study was to characterize the physical performance, skeletal muscle function, and phenotype of mice with a hereditary spastic mutation (B6.Cg-Glrb^spa/J). Motor function, gait, and physical activity of juvenile and adult spastic mice and the morphological, histological, and mechanical characteristics of their soleus and gastrocnemius medialis muscles were compared with those of their wild-type (WT) littermates. Spastic mice showed attenuated growth, impaired motor function, and low physical activity. Gait of spastic mice was characterized by a typical hopping pattern. Spastic mice showed lower muscle forces, which were related to the smaller physiological cross-sectional area of spastic muscles. The muscle-tendon complex length-force relationship of adult gastrocnemius medialis was shifted toward shorter lengths, which was explained by attenuated longitudinal tibia growth. Spastic gastrocnemius medialis was more fatigue resistant than WT gastrocnemius medialis. This was largely explained by a higher mitochondrial content in muscle fibers and relatively higher percentage of slow-type muscle fibers. Muscles of juvenile spastic mice showed similar differences compared with WT juvenile mice, but these were less pronounced than between adult mice. This study shows that in spastic mice, disturbed motor function and gait is likely to be the result of hyperactivity of skeletal muscle and impaired skeletal muscle growth, which progress with age.

Study on the Improvement of Health and Nutrition Status After a 12-week Protein-Rich Supplementation Regimen in Children and Adolescents With Brain Lesions Disorder

Through a survey on dietary intake of children and adolescents with brain lesions, the present study aimed to analyze the current status of nutrient intake and examine the effect of high-protein nutrient drink on their nutritional and muscle statuses. The study participants were 90 juvenile participants aged 8–19 years, with brain lesions. The participants were provided with a protein nutrient drink for 12 weeks and a questionnaire survey on dietary intake was performed to analyze the level of nutrient intake before and after ingestion. The physical measurements were taken to determine the improvements in nutrient and muscle statuses. The results showed that, before the intake of protein nutrient drink as a supplement, the participants exhibited lower height, weight, and body mass index than those of the standard levels of healthy individuals, and the level of nutrient intake through diet was lower than those of the required and recommended levels of nutrient intake for Koreans. Conversely, after the intake of protein nutrient drink for 12 weeks, the level of nutrient intake and physical statuses such as weight showed significant improvements. In addition, the muscle status had undergone approximately 10% of change during the intervention with no significant difference. Thus, to ensure an adequate level of nutrient supply to children and adolescents with brain lesions, there is an urgent need to develop a guideline of nutrient intake. The findings in this study are expected to serve as the basic data for such guidelines.

Percutaneous Endoscopic Gastrostomy and Nutritional Interventions by the Pediatric Nutritional Support Team Improve the Nutritional Status of Neurologically Impaired Children

Aim: To evaluate the long-term effects of nutritional improvement following percutaneous endoscopic gastrostomy (PEG) tube feeding stratified by previous feeding method and to assess the impact of underlying muscle tone on the outcomes of the nutritional intervention. Methods: Neurologically impaired children who underwent PEG tube insertion and nutritional intervention provided by a pediatric nutritional support team were enrolled. We measured anthropometric variables, laboratory parameters, and nutritional intake at baseline, 6 months after PEG insertion, and the last visit. We evaluated the percent ideal body weight (PIBW), body mass index (BMI)-for-age z-score, and percentiles and calculated the ratios of calorie intake compared to required requirement (CIR) and protein intake compared to recommended requirement (PIR). Results: The PIBW and BMI-for-age z-score improved during the first 6 months (p = 0.003 and p = 0.005, respectively). The CIR (p = 0.015) and PIR (p = 0.004) increased during the study period. The baseline BMI and PIBW of the previous nasogastric tube feeding group were better than those of the oral feeding group (p = 0.02 and p = 0.03, respectively). The BMI-for-age z-score, PIBW, CIR, and PIR improved in the hypertonic group (p = 0.03, 0.02, 0.03, and 0.01, respectively). Conclusion: PEG tube feeding and active nutritional intervention improved the nutritional status of neurologically impaired children immediately after PEG insertion. The nutritional requirements might vary by the muscle tonicity.

Development of disorder-specific normative data for growth in children with cerebral palsy

The purpose of this study was to create growth-percentiles for Caucasian children with cerebral palsy (CP). The studied parameters were height and age. In a retrospective analysis, we converted measurements collected in our center to create disorder-specific percentiles of normative data. Patients were stratified due to sex (male and female) and to mobility levels using the gross motor function classification system (GMFCS) (A = walking; GMFCS I-III, B = non walking; GMFCS IV-V) into four groups. In total, 2363 measurements in patients 0-18 years were collected. The mean age for group "Am" was 6.8 years (n = 862), group "Bm" 7.6 years (n = 563), group "Af" 7.7 years (n = 600), and group "Bf" 8.2 years (n = 366). The created percentiles for all groups were below the reference percentiles for healthy Caucasian children (KiGGS). The median curve for children with GMFCS levels I-III is slightly above the 3rd percentile, whereas the 50th percentile for GMFCS levels IV-V is mostly below the 3rd KiGGS centile.Conclusion: In conclusion, children with cerebral palsy are smaller than healthy children. The difference between 50th percentile of CP patients compared to healthy children supports the need for the use of disorder-specific growth charts. Those charts can help clinicians differentiate growth disorders in patients with CP. What is Known: • Children with cerebral palsy are shorter than healthy children and height is influenced by level of ambulation. • Currently, only reference percentiles of American children with mixed ethical backgrounds are available to evaluate growth. What is New: • This paper presents disorder-specific reference percentiles for longitudinal growth of Caucasian children with cerebral palsy depending on motor function. • These percentiles allow to asses longitudinal growth in children with cerebral palsy to detect other additional diseases impairing growth.

Nutrition of Patients with Severe Neurologic Impairment

Background

Commercial enteral formulas are generally recommended for gastrostomy feeding in patients with severe neurologic impairment. However, pureed food diets are still widely used and even gaining popularity among certain groups. We tried to compare the effectiveness of gastrostomy feeding for treatment of severe malnutrition with either enteral formulas or pureed feeds.

Patients and methods

A 6-month nutritional intervention was made with 37 malnourished children, adolescents and young adults (2–26 years old) with severe neurologic impairment (Gross Motor Function Classification system [GMFCS] grade V). The individual needs were calculated. Participants were fed by gastrostomy with either enteral formulas (n = 17) or pureed food (n = 20). Measurements to assess nutritional status were made at the beginning and at the end of intervention.

Results

The Z scores for weight-for-age and for the body-mass index increased more in enteral formula than in pureed food group (2.07 vs. 0.70, p = 0.0012; and 3.75 vs. 0.63, p = 0.0014, respectively). Fat mass index increased more in enteral formula than in pureed food group (1.12 kg/m²vs. 0.38 kg/m²; p = 0.0012). Patients in the enteral formula group showed increase in lean body mass expressed as fat-free mass index (0.70 kg/m²), while those in pureed food group did not (-0.06 kg/m²) (p = 0.0487).

Conclusions

The results suggest that even professionally planned pureed food diet is less effective than commercial enteral formula for nutritional rehabilitation of malnourished patients with severe neurologic impairment. However, larger and if possible randomised clinical studies should be made to confirm our findings.

Quality of Life Issues for Families who Make the Decision to Use a Feeding Tube for Their Child with Disabilities

Qualitative research methods were used to study families who had made or were in the process of making the decision to use a feeding tube to meet the nutrition needs of their child with a disability. Data were gathered over a 2-year period through interviews with eight families. Family decision making in the context of quality of life was examined using a theoretical family systems model. Descriptive themes and issues emerged from the data that led to a greater understanding of what families face in making this decision for their child. The data can help families and professionals work in partnership before a child becomes severely malnourished or medically compromised as a result of inadequate nutrition. The themes and issues are discussed and implications for future interventions and research are presented.

[Anthropometric evaluation of pediatric patients with non-progressive chronic encephalopathy according to different methods of classification]

Objective:

To perform anthropometric assessment of patients with quadriplegic, chronic non-progressive encephalopathy, comparing two distinct references of nutritional classification and to compare the estimated height to the length measured by stadiometer.

Method:

Cross-sectional study including 0-3-year children with quadriplegic chronic non-progressive encephalopathy in secondary public hospital. Length, weight, arm circumference, triceps skinfold and knee height were measured. The arm muscle circumference and estimated height were calculated. The following relations were evaluated: weight-for-age, length-for-age and weight-for-length, using as reference the charts of the World Health Organization (WHO) and those proposed by Krick et al.

Results:

Fourteen children with a mean age of 21 months were evaluated. Assessment of anthropometric indicators showed significant difference between the two classification methods to assess nutritional indicators length/age (p=0.014), weight/age (p=0.014) and weight/length (p=0.001). There was significant correlation between measured length and estimated height (r=0.796, p=0.001). Evaluation of arm circumference and triceps skinfold showed that most patients presented some degree of malnutrition. According to arm muscle circumference, most were eutrophic.

Conclusions:

Specific curves for children with chronic non-progressive encephalopathy appear to underestimate malnutrition when one takes into account indicators involving weight. Curves developed for healthy children can be a good option for clinical practice and weight-for-length indicator and body composition measurements should be considered as complementary tools.

Surgical intervention for feeding and nutrition difficulties in cerebral palsy: a systematic review

AIM

The aim of the study was to systematically review surgical intervention for feeding difficulties in cerebral palsy.

METHOD

We searched databases including MEDLINE from 1980 to July 2012. Two reviewers independently assessed studies and rated the overall quality and strength of the evidence.

RESULTS

Thirteen publications (11 unique studies) met the inclusion criteria and addressed gastrostomy outcomes or treatment of reflux via fundoplication. In nine studies, gastrostomy-fed children gained weight. Relative to typically developing populations, baseline weight z-scores ranged from -3.56 to -0.39 and follow-up z-scores ranged from -2.63 to -0.33. Other growth measures were mixed. Two studies assessed fundoplication: in one, both Nissen fundoplication and vertical gastric plication reduced reflux (by 57% and 43% respectively), while in one case series, reflux recurred within 12 months in 30% of children. The highest rates of adverse events across studies were site infection (59%), granulation tissue (42%), and recurrent reflux (30%). Death rates ranged from 7 to 29%; however, the underlying cause was probably not surgery.

INTERPRETATION

Evidence for the effectiveness of surgical interventions is insufficient to low. Studies of gastrostomy typically demonstrated significant weight gain. Results for other measures were mixed. Many children remained underweight, although, given a lack of appropriate reference standards, these results should be interpreted cautiously.

Gastrostomy feeding versus oral feeding alone for children with cerebral palsy

BACKGROUND

Children with cerebral palsy can be significantly disabled in terms of their ability to suck, chew and swallow. This can lead to significant impairment in feeding and, eventually, to undernutrition. It can also result in aspiration of food into the lungs. Length of feeding time may be considerably increased and, instead of being an enjoyable experience, mealtimes may be distressing for both child and carer. For children unable to maintain a normal nutritional state feeding by mouth, gastrostomy or jejunostomy tubes are increasingly being used to provide the digestive system with nutrients. A gastrostomy tube is a feeding tube inserted surgically through the abdominal wall directly into the stomach. A jejunostomy feeding tube is inserted into the jejunum, part of the small intestine, either directly or via a previous gastrostomy. Although gastrostomy or jejunostomy placement may greatly facilitate the feeding of children with cerebral palsy, many carers find it very emotionally difficult to accept this intervention. Moreover, the intervention is costly and there is the possibility of complications. The effectiveness and safety of the treatment requires further assessment. This review is an update of one previously published in 2004.

OBJECTIVES

To assess the effects of nutritional supplementation given via gastrostomy or jejunostomy to children with feeding difficulties due to cerebral palsy.

SEARCH METHODS

For this update, we searched the following databases in July 2012: CENTRAL, MEDLINE , Embase, CINAHL, Science Citation Index, Conference Proceedings Citation Index, LILACS and Zetoc. We searched for trials in ICTRP and Clinicaltrials.gov, and for theses in WorldCat and Proquest Index to Theses. We also contacted other researchers and experts in this field.

SELECTION CRITERIA

We looked for randomised controlled trials that compared delivery of nutrition via a gastrostomy or jejunostomy tube compared with oral feeding alone for children up to the age of 16 years.

DATA COLLECTION AND ANALYSIS

Screening of search results was undertaken independently by two review authors. No data extraction was possible as there were no included studies.

MAIN RESULTS

No trials were identified that met the inclusion criteria for this review.

AUTHORS' CONCLUSIONS

Considerable uncertainty about the effects of gastrostomy for children with cerebral palsy remains. A well designed and conducted randomised controlled trial should be undertaken to resolve the current uncertainties about medical management for children with cerebral palsy and physical difficulties in eating.

The growing spine: how spinal deformities influence normal spine and thoracic cage growth

PURPOSE

This article aims to provide an overview of how spinal deformities can alter normal spine and thoracic cage growth.

METHODS

Some of the data presented in this article are gathered from studies performed in 1980 and 1990, and their applicability to populations of different ethnicity, geography or developmental stage has not yet been elucidated. In the present article, older concepts have been integrated with newer scientific data available to give the reader the basis for a better understanding of both normal and abnormal spine and thoracic cage growth.

RESULTS

A thorough analysis of different parameters, such as weight, standing and sitting height, body mass index, thoracic perimeter, arm span, T1-S1 spinal segment length, and respiratory function, help the surgeon to choose the best treatment modality. Respiratory problems can develop after a precocious vertebral arthrodesis or as a consequence of pre-existing severe vertebral deformities and can vary in patterns and timing, according to the existing degree of deformity. The varying extent of an experimental arthrodesis also affects differently both growth and thoracopulmonary function.

CONCLUSIONS

Growth is a succession of acceleration and deceleration phases and a perfect knowledge of normal growth parameters is mandatory to understand the pathologic modifications induced on a growing spine by an early onset spinal deformity. The challenges associated with the growing spine for the surgeon include preservation of the thoracic spine, thoracic cage, and lung growth without reducing spinal motion.

Protein levels in enteral feeds: do these meet requirements in children with severe cerebral palsy?

Children with cerebral palsy (CP) have been documented to have feeding difficulties, which increase in line with condition severity and result in lowered growth potential. Much nutrition literature surrounds energy intake and expenditure in these children, with less information available on other parameters such as protein and micronutrients, which are also important for growth and development. We examined differences in protein intake and a variety of protein metabolism indices in children with CP compared with controls. A total of twenty-four children aged 4–12 years with marked CP fed orally (O, n 15) or enterally (E, n 9) were recruited, including age-matched typically developing children (C, n 24). Fasting blood samples were analysed for levels of albumin, creatinine, urea and urate. Parents collected an exact food replica for three consecutive days of their child's actual intake, which were directly analysed for protein content. Significant differences were found in protein intakes between the groups (mean percentage minimum requirements: E = 178 (sd 47); O = 208 (sd 95); C = 311 (sd 119), P = 0·005). Despite all children consuming over recommended levels, children with CP had significantly reduced levels of the protein metabolic indices compared with controls. These include as z-scores: albumin mean C = 0·71 (sd 1·04) and CP = − 0·17 (sd 1·60), P = 0·03; creatinine C = − 2·06 (sd 0·46) and CP = − 3·11 (sd 0·98), P < 0·001; urate C = 0·18 (sd 0·62) and CP = − 0·58 (sd 0·93), P = 0·002. Post hoc analysis, the present data show potentially greater protein metabolism issues in enterally fed children, compared with the other groups. This may also support recent literature that suggests shortfalls in current recommendations.

Low weight, morbidity, and mortality in children with cerebral palsy: new clinical growth charts

OBJECTIVE

To determine the percentiles of weight for age in cerebral palsy according to gender and Gross Motor Function Classification System (GMFCS) level and to identify weights associated with negative health outcomes.

PATIENTS AND METHODS

This study consists of a total of 102 163 measurements of weight from 25 545 children with cerebral palsy who were clients of the California Department of Developmental Services from 1988 through 2002. Percentiles were estimated using generalized additive models for location, scale, and shape. Numbers of comorbidities were compared using t tests. The effect of low weight on mortality was estimated with proportional hazards regression.

RESULTS

Weight-for-age percentiles in children with cerebral palsy varied with gender and GMFCS level. Comorbidities were more common among those with weights below the 20th percentile in GMFCS levels I through IV and level V without feeding tubes (P < .01). For GMFCS levels I and II, weights below the 5th percentile were associated with a hazard ratio of 2.2 (95% confidence interval: 1.3-3.7). For children in GMFCS levels III through V, weights below the 20th percentile were associated with a mortality hazard ratio of 1.5 (95% confidence interval: 1.4-1.7).

CONCLUSIONS

Children with cerebral palsy who have very low weights have more major medical conditions and are at increased risk of death. The weight-for-age charts presented here may assist in the early detection of nutritional issues or other health risks in these children.

The effect of gastrostomy tube feeding on body protein and bone mineralization in children with quadriplegic cerebral palsy

AIM

The aim of this study was to investigate the effect of gastrostomy tube feeding on body protein and bone mineralization in malnourished children with cerebral palsy (CP).

METHOD

Children aged between 4 and 18 years with spastic quadriplegic CP (Gross Motor Function Classification System level V) were recruited from the Children's Hospital at Westmead to participate in this prospective cohort study. The children had measurements of anthropometry (weight, height, and skinfold), bone mineral content (BMC) by dual-energy X-ray absorptiometry, and total body protein (TBP) by neutron activation analysis before and after gastrostomy tube feeding. Comparison data were collected prospectively from age-matched healthy children and extracted from databases for this study.

RESULTS

A total of 21 children (nine females, 12 males) participated in the study (median age 8 y 5 mo; interquartile range [IQR] 6 y 9 mo-11 y 10 mo). The median length of time of gastrostomy feeding was 19.4 months (IQR 7.7-29.9 mo). Significant (p<0.05) improvements were found in the median values for weight (15.4-23.3 kg), weight standard deviation scores (SDS; -4.8 to -3.0), height (105.4-118.3 cm), per cent body fat (10.7-16.3), TBP (2.4-3.4 kg), TBP per cent predicted for height (83.4-99.0), and BMC (469-626 g). No significant increases were found in height SDS, TBP per cent predicted for age, or BMC SDS for age or height.

INTERPRETATION

Malnourished children with quadriplegic CP showed significant increases in body fat and protein with gastrostomy tube feeding. No significant change in bone mineralization predicted for age or height was observed.

The relationship between fractures and DXA measures of BMD in the distal femur of children and adolescents with cerebral palsy or muscular dystrophy

Children with limited or no ability to ambulate frequently sustain fragility fractures. Joint contractures, scoliosis, hip dysplasia, and metallic implants often prevent reliable measures of bone mineral density (BMD) in the proximal femur and lumbar spine, where BMD is commonly measured. Further, the relevance of lumbar spine BMD to fracture risk in this population is questionable. In an effort to obtain bone density measures that are both technically feasible and clinically relevant, a technique was developed involving dual-energy X-ray absorptiometry (DXA) measures of the distal femur projected in the lateral plane. The purpose of this study is to test the hypothesis that these new measures of BMD correlate with fractures in children with limited or no ability to ambulate. The relationship between distal femur BMD Z-scores and fracture history was assessed in a cross-sectional study of 619 children aged 6 to 18 years with muscular dystrophy or moderate to severe cerebral palsy compiled from eight centers. There was a strong correlation between fracture history and BMD Z-scores in the distal femur; 35% to 42% of those with BMD Z-scores less than -5 had fractured compared with 13% to 15% of those with BMD Z-scores greater than -1. Risk ratios were 1.06 to 1.15 (95% confidence interval 1.04-1.22), meaning a 6% to 15% increased risk of fracture with each 1.0 decrease in BMD Z-score. In clinical practice, DXA measure of BMD in the distal femur is the technique of choice for the assessment of children with impaired mobility.

Improved weight attainment of extremely low-gestational-age infants with bronchopulmonary dysplasia

OBJECTIVE

To determine whether changes in neonatal practice and morbidity since 2000 have improved the growth attainment of infants with bronchopulmonary dysplasia (BPD).

STUDY DESIGN

We compared the respective z-scores of the weight, length and head circumference of extremely low-gestational-age infants (aged <28 weeks) with BPD at birth, 40 weeks and 20 months corrected age (CA) during two time periods, namely period I, 1996-1999 (n=117) and period II, 2000-2003 (n=105), and examined the effects of significant changes in neonatal practice, morbidities and neurosensory outcome on 20-month growth outcomes.

RESULT

During the most recent period (2000-2003), there was a significant increase in mean weight z-scores (-1.60 vs -1.22) and decrease in rates of subnormal weight (40 vs 21%), P<0.05 at 20 months CA but not in those of length or head circumference. Significant predictors of the 20-month weight z-score included time period (period I vs II), duration of ventilator dependence and 20-month neurosensory abnormality (all P<0.05).

CONCLUSION

Despite an improvement in weight since 2000, poor growth attainment remains a major problem among infants with BPD.

Crescimento e antropometria em pacientes com paralisia cerebral hemiplégica

OBJETIVO: Analisar o crescimento linear, o perímetro cefálico e as diferenças antropométricas entre o lado envolvido e o não-envolvido de 24 crianças com paralisia cerebral (PC) hemiplégica, comparados à média para a idade. MÉTODOS: Estudo transversal com amostragem consecutiva de crianças com PC, classificadas clinicamente como hemiplegia espástica. As medidas antropométricas incluíram: peso, estatura, perímetro cefálico, comprimento total de membro superior, comprimento da mão, largura da palma da mão, comprimento total do membro inferior, comprimento do pé e a circunferência dos membros (braço, coxa e panturrilha). As diferenças antropométricas entre os dimídios foram calculadas em centímetros e como porcentagem de encurtamento, comparando o lado envolvido com o não-envolvido. Dois referenciais populacionais, tabelas de crescimento e o software ABase®, desenvolvido para sistema PalmOS, foram comparados na classificação das medidas do comprimento da mão e do pé. A análise estatística utilizou o coeficiente de correlação de Spearman para avaliar a associação entre variáveis quantitativas e o teste não-paramétrico de Wilcoxon para comparar as medidas do lado envolvido e não-envolvido. RESULTADOS: As médias de peso, estatura e perímetro cefálico se mostraram dentro dos limites normais para a idade e 21% dos pacientes apresentaram microcefalia. A discrepância entre os dimídios foi evidente em todos os casos, sendo maior na largura e comprimento da mão. Houve correlação da dis observada entre os membros superiores e inferiores no lado envolvido (r=0,48) e a discrepância aumenta com a idade (r=0,44). CONCLUSÕES: O maior comprometimento no crescimento das crianças com paralisia cerebral estudadas ocorreu nos membros envolvidos pela hemiplegia e, em menor proporção, no perímetro cefálico.

Longitudinal change in muscle and fat thickness in children and adolescents with cerebral palsy

AIM

In a prospective, longitudinal study, we investigated the influence of the severity of motor impairment on changes in body characteristics in children with moderate-to-severe cerebral palsy (CP).

METHOD

Twenty-six single children and adolescents (15 females, 11 males; mean age 10y 6mo, SD 3y 3mo) with spastic (quadriplegia, hemiplegia, or diplegia), athetotic, or hypotonic CP at Gross Motor Function Classification System (GMFCS) levels III to V participated. They were categorized into moderate (GMFCS levels III or IV, n=11) and severe (GMFCS level V, n=15) groups. Muscle thickness of the quadriceps femoris (MTQ) and fat thickness of the anterior thigh (FTA) measured using ultrasound images, together with weight and height, were obtained at annual measurements over 3 years.

RESULTS

Significant increases in all variables were found in both groups. The areas under the curve (AUCs: an index of the gain) for weight, MTQ, and FTA were significantly higher in the moderate group. The AUC for weight, adjusted for height, was significantly correlated with the AUC for MTQ in the moderate group, and with the AUC for FTA in the severe group.

INTERPRETATION

Weight gain in children with severe CP does not necessarily reflect muscle growth.

Gastrostomy placement improves height and weight gain in girls with Rett syndrome

BACKGROUND

Growth failure and undernutrition complicate the clinical course of girls with Rett syndrome (RTT). These abnormalities are, in part, the consequence of oral motor dysfunction and inadequate dietary intake.

OBJECTIVE

To determine whether gastrostomy placement for nutritional therapy alters the natural history of growth failure and undernutrition in RTT.

HYPOTHESIS

We hypothesized that gastrostomy placement for nutritional therapy reverses the decline in height, weight, and body mass index (BMI) z scores in RTT.

METHODS

Standard stadiometric and anthropometric measures were obtained to derive height, weight, and BMI z scores and estimates of fat-free mass (FFM) and body fat in a cohort of girls (n = 92) with RTT before and after gastrostomy placement. Methyl-CpG-binding protein 2 (MECP2) mutations and the presence or absence of a fundoplication were recorded.

RESULTS

The differences in height (n = 73), weight (n = 81), and BMI (n = 81) z score slopes before and after gastrostomy placement were 1.31 + 2.06 (P < 0.001), 2.38 +/- 3.18 (P < 0.001), and 3.25 +/- 3.32 (P < 0.001), respectively. FFM and body fat (n = 43) increased after gastrostomy by 41 +/- 27 g/cm height (P < 0.001) and 7.5% +/- 5.7% body weight (P < 0.001), respectively. The differences in height, weight, and BMI z score slopes were similar regardless of the age at which the gastrostomy was placed. The differences in height, weight, and BMI z score slopes, as well as the change in FFM and body fat deposition after gastrostomy placement, did not differ between those who did or did not have a fundoplication and among the classes of MECP2 mutations.

CONCLUSION

Gastrostomy placement for aggressive nutritional therapy favorably altered the natural history of growth failure and undernutrition in RTT, but did not restore height and weight z scores to birth values, regardless of the age at which surgery occurred and in the presence or absence of a fundoplication.

Growth and nutritional status in residential center versus home-living children and adolescents with quadriplegic cerebral palsy

OBJECTIVE

To describe growth and nutrition in nonambulatory youth (<19 years of age) with cerebral palsy (CP) living in residential centers compared with similar youth living at home.

STUDY DESIGN

A multicenter, cross-sectional, single observational assessment of 75 subjects living in a residential care facility compared with 205 subjects living at home. Primary outcome measures included anthropometric measures of height, weight, triceps, and subscapular skinfolds, and mid-upper-arm muscle area. Z scores were calculated from reference values for healthy children. Age, use of a feeding tube, and Gross Motor Functional Classification System (GMFCS) level were included as important confounders.

RESULTS

Use of a feeding tube was associated with higher skinfold Z scores, and a significantly higher percentage of the residential subjects had a feeding tube. Height, weight, and arm-muscle area Z scores all diverged (negatively) from reference values with age, and the residential subjects were on average older than the home-living subjects. After controlling for age, GMFCS level and use of a feeding tube, residential living was associated with significantly greater weight, height, skinfold thicknesses, and mid-arm muscle area Z scores.

CONCLUSION

Poor growth and nutrition in children with CP is a prevalent, important, and complex problem. Although factors intrinsic to the condition of CP likely play a significant role, it is also clear that environmental factors, including the living situation of the child, can have an impact.

Evaluation of physical growth in cerebral palsied children and its possible relationship with gross motor development

The object of this study was to detect any possible relation between the current gross motor function score for cerebral palsy children and their physical growth parameters. We measured 71 children with spastic cerebral palsy (35 diplegic, 25 quadriplegic and 11 hemiplegic) and a control group of 80 normal children. Measures taken for cerebral palsy and normal children included stature, weight, head circumference and mid upper-arm circumference, and, additionally for the cerebral palsied children, duration of the disease, birth weight, presence or absence of orofacial dysfunction, distribution of paralysis and degree of spasticity. Motor abilities were measured using the Gross Motor Function Measure. Results showed a significant decrease in the stature, current weight, head circumference and mid upper-arm circumference of both sexes of the quadriplegic children, and significant decreases in the current weight of the diplegic girls and the head circumference of the hemiplegic girls. There were also significant decreases in all scores of the quadriplegic children compared to the diplegic and hemiplegic children. Diplegic children had significantly decreased standing, walking and running, and total scores, compared to the hemiplegic children. Total score at age of testing was independently predicted by the duration of the disease, distribution of paralysis, presence or absence of orofacial dysfunction, spasticity index and the current body weight. Our findings indicate that in spastic cerebral palsy the physical growth parameters were markedly decreased in the quadriplegic form compared to other forms. Only current body weight, from the growth parameters, in addition to other relevant clinical data, can be considered predictors of the current gross motor abilities of those children.

Feeding difficulties in disabled children leads to malnutrition: experience in an Indian slum

The aim of the present study was to explore the nature, extent and probable causes of nutritional deficiencies among children with disabilities living in Dharavi, a slum in Mumbai, India. A cross-sectional study was conducted to investigate whether the nutritional status of children with disabilities, aged 2–6 years (n141), was worse than that of non-disabled sibling controls (n122) and neighbour controls (n162). Data on food patterns, anthropometry, micronutrient status and feeding difficulties reported by parents were collected. The mean weight for age of the children with disabilities (−2·44 (sd 1·39)Zscores;n120) was significantly lower (P<0·05) compared with the sibling (−1·70 (sd 1·20)Zscores;n109) and neighbour (−1·83 (sd 1·290)Zscores;n162) control groups. The children with disabilities had significantly lower (P<0·05) mean haemoglobin levels (92 (sd 23) g/l;n134) compared with siblings (102 (sd 18) g/l;n103) and neighbours (99 (sd 18) g/l;n153). Relative risk (RR) analysis indicated that the disabled children with feeding difficulties were significantly more likely (P<0·05) to be malnourished, by the indicator of weight for age (RR 1·1; 95 % CI 1·08, 1·20) compared with the disabled children without a feeding difficulty. They were also significantly more likely to be malnourished using the indicators of height for age (RR 1·3; 95 % CI 1·19, 1·43) and weight for height (RR 2·4; 95 % CI 1·78, 3·23) compared with the disabled children without a feeding difficulty. Feeding difficulties were identified as a risk factor for vulnerability to inadequate nutritional status among children with disabilities.

Growth patterns in a population of children and adolescents with cerebral palsy

This study examined growth of children and adolescents with cerebral palsy (CP) who received services from the California Department of Developmental Services from 1987 to 2002. In all, 141 961 measurements of height and weight were taken from 24920 patients with CP (14103 males, 10817 females). Centiles of weight and height were determined by age, sex, and five levels of functional ability ranging from fully ambulatory to unable to walk, crawl, or feed self, and fed via gastrostomy tube. Resulting charts of height and weight centiles were compared with Centers for Disease Control and Prevention weight and height charts for the general population of the US. Centiles of height and weight of patients with CP were close to those of the general population for the highest functioning groups with CP, but lagged substantially for other groups. Presence of a feeding tube was associated with greater height and weight in the lowest functioning groups, with centiles for weight being 2 to 5 kg higher for those with gastrostomy tubes. The charts may assist in early identification of nutritional or metabolic difficulties beyond what might be expected for patients with similar functional disabilities.

Survival in cerebral palsy in the last 20 years: signs of improvement?

This study investigated the possibility of improved survival in cerebral palsy (CP) over a 20-year period. Participants were 47 259 persons with CP receiving services from the State of California between 1983 and 2002. The person-year approach was used. This asks whether the probability of dying in a given calendar year changes over the study period after age and severity of disability are taken into account. An appreciable improvement over time was found in children with severe disabilities and in adults who required gastrostomy feeding. In these groups, mortality rates fell by 3.4% per year. Therefore, life expectancies reported in earlier studies should be increased by approximately 5 years if adjustments to 2002 mortality rates are made. For other persons with CP there was, at most, a small improvement over the 20-year period. The results suggest there have been improvements in the treatment and care of the most medically fragile children. Gastrostomy feeding has become much more widespread over the past two decades, and the improved survival of persons with gastrostomies may reflect better understanding of their requirements.

Nutrition support for neurologically impaired children: a clinical report of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition

Undernutrition, growth failure, overweight, micronutrient deficiencies, and osteopenia are nutritional comorbidities that affect the neurologically impaired child. Monitoring neurologically impaired children for nutritional comorbidities is an integral part of their care. Early involvement by a multidisciplinary team of physicians, nurses, dieticians, occupational and speech therapists, psychologists, and social workers is essential to prevent the adverse outcomes associated with feeding difficulties and poor nutritional status. Careful evaluation and monitoring of severely disabled children for nutritional problems are warranted because of the increased risk of nutrition-related morbidity and mortality.

Reduced body protein in children with spastic quadriplegic cerebral palsy

BACKGROUND

No studies have directly measured body protein or validated skinfold-thickness anthropometry and dual-energy X-ray absorptiometry (DXA) to assess body protein in children with spastic quadriplegic cerebral palsy (SQCP).

OBJECTIVE

We aimed to measure and evaluate body protein and to determine whether skinfold-thickness anthropometry and DXA can predict body protein in children with SQCP.

DESIGN

This was a cross-sectional study of 59 children (22 girls, 37 boys) aged 3.9-19.5 y with SQCP. The children underwent measurements of anthropometric indexes, lean tissue mass by DXA (LTM(DXA)), and total body protein by neutron activation analysis (TBP(NAA)). In addition, TBP was estimated from both skinfold-thickness anthropometry (TBP(SKIN)) and DXA (TBP(DXA)). The agreement of TBP(SKIN) and TBP(DXA) was tested against TBP(NAA) by using Bland and Altman plot analysis.

RESULTS

Height and weight SD scores (x +/- SD: -3.1 +/- 1.6 and -4.8 +/- 5.3, respectively) were significantly lower than reference data in the children with SQCP (P < 0.001). TBP(NAA) for age and height was low in the children with SQCP (P < 0.001): 56.1 +/- 17.3% and 81.5 +/- 15.7%, respectively, of the values predicted from control data. TBP(SKIN) and TBP(DXA) were both highly correlated with TBP(NAA): r = 0.90, P < 0.001, and r = 0.91, P < 0.001, respectively. Despite these significant correlations, agreement analyses showed wide variation of up to 33.3% of the mean for both methods.

CONCLUSIONS

Body protein in children with SQCP is significantly reduced for age and height. Skinfold anthropometry and DXA show wide variation in estimation of body protein compared with NAA in this group of children.

Weight-for-height values and limb anthropometric composition of tube-fed children with quadriplegic cerebral palsy

OBJECTIVE

Research has shown that growth retardation among children with quadriplegic cerebral palsy (CP) is often attributed to feeding dysfunction and malnutrition. The study compared weight-for-height values and limb anthropometric composition of nasogastric and gastrostomy tube-fed children with quadriplegic CP with those of orally fed children with quadriplegic CP and normal children, to examine the plausible effects of tube feeding on weight-for-height, fat, and muscle values for children with quadriplegic CP.

METHODS

Triceps, anterior mid-thigh, and medial calf skinfold thicknesses and the corresponding circumferences of the right or less affected side were measured. The subjects consisted of 119 normal children and 62 orally fed and 48 tube-fed children with quadriplegic CP. Body weight and height were recorded. For children with CP whose height could not be measured, height was estimated from the ulna length. Weight-for-height z scores, limb skinfold thicknesses, fat areas, skinfold-corrected muscle girths, and muscle areas of the children were compared.

RESULTS

Tube-fed children with CP had normal mean weight-for-height z scores. Weight-for-height z scores of the orally fed children with CP were significantly below those of normal children and tube-fed children with CP. For children with CP, whereas triceps skinfold thickness seemed to predict the mid-upper arm fat area correctly, leg skinfold thicknesses seemed to overestimate the corresponding fat areas. Stepwise multiple regression analysis showed that triceps skinfold thicknesses had good correlation (r = 0.86) and the presence of CP had nonsignificant correlation with mid-upper arm fat areas. Multiple regression analysis of fat areas with skinfold thicknesses and the presence of CP, however, showed that CP was correlated negatively (partial correlation of CP: thigh, -0.45; calf, -0.53) with thigh and calf fat areas. Although skinfold-corrected mid-upper arm muscle girths of children with CP were quite similar to those of normal children, leg muscle girths were much reduced for both orally fed and tube-fed children with CP. The apparent thickening of leg skinfold thicknesses among children with CP probably was attributable to disproportional leg muscle wasting, with resulting reduced internal circumference of the subcutaneous fat layer. For tube-fed children with CP, skinfold thicknesses and fat areas were increased significantly, although their leg skinfold-corrected muscle girths and areas remained reduced.

CONCLUSIONS

Skinfold thickness may overestimate the fat area in the affected limb with significant muscle wasting for children with CP. The condition was particularly obvious in the leg, where muscle wasting was prominent. Because leg muscles represent approximately one quarter of the normal body weight, low weight-for-height values among children with CP can be caused by leg muscle wasting attributable to disuse atrophy, which is unlikely to be correctable with tube feeding. Tube feeding may improve body weight mainly through fat deposition.

Skeletal maturation in children with quadriplegic cerebral palsy

Skeletal growth abnormalities, including diminished linear growth and osteoporosis, are well recognized in children with severe cerebral palsy (CP). The purpose of this study was to examine skeletal bone age, another aspect of skeletal growth, in this severely handicapped population. The study consisted of two parts, each assessing skeletal maturation but using different methods on different cohorts of children with CP: 133 hand-wrist radiographs were scored using the Fels method and 241 pelvis radiographs were scored using the Oxford method. The Oxford method has not been validated against contemporary normal children; therefore, 114 recently obtained pelvis radiographs of otherwise normal children being evaluated for trauma were included as controls. On average, there was not a statistically significant difference between the chronological age of the child with CP and the skeletal age based on hand-wrist x-rays. Similarly, average pelvic skeletal maturity scores did not differ between the CP children and age-matched contemporary controls. While averages did not differ, wide individual variation was noted in the CP cohorts, with a high prevalence of both delayed and advanced skeletal maturity. Of note, pelvic maturity scores in the contemporary controls significantly differed from those reported in the original Oxford series from over 50 years ago.

Gastrostomy feeding versus oral feeding alone for children with cerebral palsy

BACKGROUND

Children with cerebral palsy (CP) can be significantly disabled in terms of their ability to suck, chew and swallow. This can lead to significant impairment in feeding ability and, eventually, to under-nutrition. It can also result in aspiration of food into the lungs. Feeding time may be considerably increased and, instead of being an enjoyable experience, mealtimes may be distressing for both the child and carer. Increasingly for children unable to maintain a normal nutritional state feeding by mouth, gastrostomy or jejunostomy tubes are being used to provide the digestive system with nutrients. A gastrostomy tube is a feeding tube inserted surgically through the abdominal wall directly into the stomach. A jejunostomy feeding tube is inserted into the jejunum, part of the small intestine, either directly or via a previous gastrostomy. Although gastrostomy or jejunostomy placement may greatly facilitate feeding of children with CP, many carers find it very difficult to accept this intervention emotionally. The treatment is also relatively costly. For all of these reasons, its effectiveness requires assessment.

OBJECTIVES

To assess the effects of nutritional supplementation given via gastrostomy or jejunostomy in children with feeding difficulties due to cerebral palsy.

SEARCH STRATEGY

We searched the Cochrane Library's register of controlled trials (CENTRAL) up to Issue 4, 2003, MEDLINE 1977 - December 2003, EMBASE 1980 - December 2003, CINAHL 1982 - December 2003, LILACS 1980 - end 2003, ASLIB 1983 - 2003 and Dissertation Abstracts 1980 - 2003.

SELECTION CRITERIA

Only randomised controlled trials which compared delivery of nutrition via a gastrostomy or jejunostomy tube compared with oral feeding alone for children up to the age of 16 were considered for this review.

DATA COLLECTION AND ANALYSIS

Selection of trials, data extraction and assessment of trial quality were undertaken independently by two reviewers.

MAIN RESULTS

No trials were identified that met the inclusion criteria for this review.

REVIEWERS' CONCLUSIONS

On the basis of this systematic review, considerable uncertainty about the effects of gastrostomy for children with cerebral palsy remains. A well designed and conducted randomised controlled trial should be undertaken to resolve the current uncertainties about medical management for children with cerebral palsy and physical difficulties in eating.

Management of cerebral palsy: the neurologist's view

Cerebral palsy is a complex disorder which compromises motor abilities. Other systems are often involved and its effects on the child and their family may be profound. This article examines clinical aspects of cerebral palsy and discusses the approach to comprehensive management, with particular reference to the role of the neurologist.

Bone density and metabolism in children and adolescents with moderate to severe cerebral palsy

OBJECTIVES

Diminished bone density and a propensity to fracture with minimal trauma are common in children and adolescents with moderate to severe cerebral palsy (CP). The purpose of this study was to provide a detailed evaluation of bone mineral density (BMD) and metabolism in this population and to assess the relationship of these measures to multiple other clinical, growth, and nutrition variables.

METHODS

The study group consisted of 117 subjects ages 2 to 19 years (mean: 9.7 years) with moderate to severe CP as defined by the Gross Motor Functional Classification scale. Population-based sampling was used to recruit 62 of the participants, which allows for estimations of prevalence. The remaining 55 subjects were a convenience sampling from both hospital- and school-based sources. The evaluation included measures of BMD, a detailed anthropometric assessment of growth and nutritional status, medical and surgical history, the Child Health Status Questionnaire, and multiple serum analyses. BMD was measured in the distal femur, a site specifically developed for use in this contracted population, and the lumbar spine. BMD measures were converted to age and gender normalized z scores based on our own previously published control series (n > 250).

RESULTS

Osteopenia (BMD z score <-2.0) was found in the femur of 77% of the population-based cohort and in 97% of all study participants who were unable to stand and were older than 9 years. BMD was not as low in the lumbar spine (population-based cohort mean +/- standard error z score: -1.8 +/- 0.1) as in the distal femur (mean z score: -3.1 +/- 0.2). Fractures had occurred in 26% of the children who were older than 10 years. Multiple clinical and nutritional variables correlated with BMD z scores, but interpretation of these findings is complicated by covariance among variables. In stepwise regression analyses, it was found that severity of neurologic impairment as graded by Gross Motor Functional Classification level, increasing difficulty feeding the child, use of anticonvulsants, and lower triceps skinfold z scores (in decreasing order of importance) all independently contribute to lower BMD z scores in the femur.

CONCLUSIONS

Low BMD is prevalent in children with moderate to severe CP and is associated with significant fracture risk. The underlying pathophysiology is complex, with multiple factors contributing to the problem and significant variation between different regions of the skeleton.

Changes in skeletal maturation and mineralization in children with cerebral palsy and evaluation of related factors

Sixty-nine (28 females, 41 males) children with spastic cerebral palsy and 26 (13 females, 13 males) healthy children were included in the study. Total- and partial-body bone mineral content and bone mineral density values of patient and control subjects were measured by dual-energy x-ray absorptiometry. Left hand and wrist radiographs of all patients and right hand and wrist radiographs of 39 randomly selected patients were taken, and the bone ages of all radiographs were determined. In both female and male tetraplegics, bone mineralization values of lower extremities, where the mobility disorder and effects of absence of weight-bearing activity were maximal, were lower than those of controls and hemiplegics (P < .05). In 47 (68%) patients, left-side bone age values were below normal ranges for their ages, and the difference was statistically significant (P < .01). Our results indicate that motor function handicap affects skeletal mineralization adversely, and skeletal maturation is frequently delayed in children with cerebral palsy. We speculated that this delay might be a result of disrupted embryologic skeletal development due to hypoxic attack, which also causes the disease.

Technical aspects of feeding the disabled child

Children with neurological impairment frequently have difficulties in consuming sufficient energy and other nutrients to maintain adequate nutritional status. Under-nutrition is a significant contributory factor to growth failure. Eating may be distressing and time-consuming for the child and carer. Aspiration of feeds is common and may predispose to chronic chest infections. Gastro-oesophageal reflux is also common and may contribute to significant morbidity. This paper discusses some of the issues involved in the nutritional management of neurologically impaired children.

Cerebral Palsy

The neurorehabilitation program for cerebral palsy changes over time. During the first 2 years of life, an infant stimulation program with an emphasis on more than just improving motor deficits is emphasized. The importance of involvement of a knowledgeable therapist cannot be overemphasized. Realistic expectations must be articulated firmly. Rather then cautiously attempting to correct a dysfunction that cannot be corrected, the therapist should help the patient develop compensation techniques; the severity of the disability frequently militates against the development of "normal" motor control. Educating the parents about cerebral palsy, showing how positioning can be an effective way of helping the child be mobile, and encouraging parent-child interaction are aspects of an infant stimulation program. The therapist should serve as a coach to the parents, who implement much of the actual treatment on a daily basis at home. From 2 to 5 years of age, rapid growth occurs, and muscle tone will either develop or worsen--the latter leading not only to the development of contracture but also to a decrease in mobility. In developing a program to control this muscle tone, the most important question to be answered is, Can I improve the patient's function and decrease the patient's disability by altering muscle tone? It is not uncommon for the real problem preventing the patient from performing certain functions to be lack of motor control or lack of sensation and not the abnormal muscle tone. Between 5 and 10 years of age, the child begins to approach adult height. At this time, definitive orthopedic intervention can be considered; as already noted, contracture development occurs as a result of abnormal muscle tone in combination with growth. Finally, as the child approaches the teen years, issues of sitting and hygiene are important considerations, especially in the nonambulatory patient. The problem of pain secondary to spasticity or dystonia must be addressed.

Living with cerebral palsy and tube feeding: A population-based follow-up study

OBJECTIVES

To assess the impact of surgically placed feeding tubes on children with severe cerebral palsy (CP) and their families and to determine the survival of these children after initiation of tube feeding (TF).

METHODS

Virtually all children from Nova Scotia who had gastrostomy or jejunostomy procedures between the years 1980 and 1998 and who had been diagnosed with CP were identified. Caretakers of those children who had TF initiated in the last 8 years were evaluated by using a semi-structured interview. Names of children who had not had recent follow-up visits were submitted to the provincial Vital Statistics office to determine whether they had died. Data from patients who were tube-fed between 1980 and 1989 were then used in combination with data from the more recent cases to create a survival curve.

RESULTS

A total of 61 children were identified; 16 had died. Forty of 45 eligible families were interviewed; 90% were pleased with the effect of TF on their child and family life. Negative reports were associated with increased stress related to feeding. Survival rates after gastrostomy and/or jejunostomy were 83% after 2 years and 75% after 7 years.

CONCLUSIONS

In children with severe CF, initiation of TF improved the quality of life for both the child and family in 90% despite frequent minor complications.

Improvement of children's nutritional status after enteral feeding by PEG: an interim report

BACKGROUND

Enteral feeding by percutaneous endoscopic gastrostomy is indicated as long-term nutritional support for children with neurologic impairment and dysphagia. We report our experience with percutaneous endoscopic gastrostomy and evaluate the age range of children with cerebral palsy who benefit most with weight and height gain.

METHODS

In a prospective study, from August 1996 to August 1997, 20 endoscopic gastrostomies were performed in 20 children diagnosed with cerebral palsy (16), myopathy (2), and brain trauma (2). The mean age was 6.5 years and the mean follow-up 5.9 months. All patients had severe mental impairment and oropharyngeal dysphagia. They were followed up monthly on an outpatient basis by both the gastroenterologist and the dietitian, who assessed gastrostomy complications and performed anthropometric measurements.

RESULTS

All 20 patients benefited from enteral nutrition with a statistically significant gain in weight (p < 0.01), and there was a trend toward improved weight/height ratio in children under 4 years of age according to Z-score and mid-arm muscle area (p < 0.01). Triceps skinfold thickness failed to reach statistical significance. There were no immediate complications related to the procedure. Perforations occurred with three (15%) tubes, and the plugs for introduction of food had to be replaced after 4 months of use. All complications, namely formation of granulation tissue at the stoma (7), stoma infection (4), gastroesophageal reflux pneumonia (3), and pneumoperitoneum (1) were managed clinically.

CONCLUSIONS

Endoscopic gastrostomy is a safe procedure for children. Enteral feeding resulted in a trend toward a normalized weight/height ratio for children with cerebral palsy younger than 4 years and significant weight gain in those older than 12 years.

Linear growth velocity in children with cerebral palsy

Retrospective analysis of an anthropometric database collected prospectively in children with cerebral palsy (CP) was carried out to evaluate linear growth velocity and identify risk factors for poor linear growth. Growth velocity measures were compared with published norms for prepubertal growth velocity and z scores were calculated. Mean growth velocity z score (Gvz) was -0.97+/-1.9. Boys grew more slowly than girls (mean Gvz = -1.5+/-1.9 versus -0.3+/-1.7 P = 0.003). Gvz did not correlate with type of CP or presence/absence of microcephaly. Young age was a risk factor for poor linear growth (mean Gvz = -2.40+/-2.6 for children under 2 years of age versus -0.76+/-1.9 ages 2 to 6 and -0.77+/-1.6 ages 6 to 10, P = 0.04). Children at nutritional risk (triceps skinfold thickness < or =55%) grew poorly (mean Gvz = -1.46+/-1.5 versus -0.30+/-1.8, P = 0.01). For children over 2 years, those with cognitive impairments grew more slowly than those with normal cognition (mean Gvz = -1.25+/-1.9 versus -0.12+/-1.8, P = 0.02) and non-ambulatory children grew more slowly than ambulatory children (mean Gvz = -1.20+/-1.5 versus -0.35+/-1.9, P = 0.03). Prepubertal children with CP grow more slowly than expected compared with age- and sex-based standards. Sex, age, cognitive impairment, ambulatory status, and nutritional state are factors which may contribute to slow growth. These results add to the growing data that children with CP have unique growth patterns. Further study is needed to clarify the factors which contribute to poor linear growth in this population.

Feeding the disabled child

Feeding difficulty and malnutrition are common in disabled children. Intake may be reduced because of anorexia, chewing and swallowing difficulties, or vomiting. Feeding is often time consuming, unpleasant, and may result in aspiration. Malnutrition may result in impaired growth and neurodevelopment, and impaired cardiorespiratory, gastrointestinal, and immune functions. Multidisciplinary assessment is recommended and should include a feeding history, oral-motor examination, and nutritional assessment. The energy requirements of most disabled children are less than those for a normal child of the same age but may be increased by spasticity, athetosis, convulsions, and recurrent infections. Micronutrient deficiencies may occur even in children receiving nutritionally complete feeds if the volume is reduced because of low energy requirements. Oral intake may be improved by a change of posture, special seating, feeding equipment, oral desensitization, mashing or pureeing of lumpy food, thickening of liquids, use of calorie supplements, and treatment of reflux/esophagitis. Non-oral feeding should be considered when oral feeding is unsafe, not enjoyable, inadequate, or very time consuming. Long-term support requires a gastrostomy. This is less obtrusive than a nasogastric tube, less likely to become displaced, less traumatic, and is associated with improved quality of life, but is also associated with significant morbidity. If there is symptomatic reflux a fundoplication may be required, but this is associated with significant mortality and substantial morbidity.

Growth of preterm infants with cystic periventricular leukomalacia

Etiology of the high rates of growth failure in children with cerebral palsy (CP) remains unclear. The purpose of this study was to evaluate the relation between growth failure in preterm infants with cystic periventricular leukomalacia (CPVL) and neonatal health complications. The population consisted of all preterm infants (51) with a gestational age of <33 weeks who were admitted to the Children's Hospital of Buffalo from 1988 to 1993 and who had CPVL. Out of the 41 survivors with CPVL who were followed, 39 developed CP and 18 developed growth failure during infancy. At the time of greatest growth failure, the majority (72%) of infants had signs of undernutrition as defined by the Waterlow (1972) classification. Oral feeding impairment was the sole risk factor for the occurrence of growth failure. Undernutrition appears to be important in the occurrence of growth failure in preterm infants with CPVL and CP.

A comparative longitudinal study of gastrostomy devices in children

Long-term gastrostomy is a predictable intervention to ameliorate the effects of feeding and swallowing difficulties among children with severe spastic cerebral palsy. The evidence evaluating the efficacy and implications of the available gastrostomy devices in common use has focused primarily on the operative phase, ignoring the long-term effects that may be critical from a nurse's or family caregiver's point of view. In this study, the authors describe a sample of children with gastrostomy, comparing skin-level and tube devices on measures of nutritional outcome, complications, and caregiver satisfaction. In contrast to manufacturer's claims about the superiority of skin-level devices, the results presented here reveal few differences between the devices. The authors conclude, therefore, that device selection should be determined by individualized comprehensive assessment of the child and family circumstances.

Caregivers' perceptions following gastrostomy in severely disabled children with feeding problems

Feeding difficulties are common in neurologically impaired children, often leading to great distress and frustration in the child and family. A gastrostomy may be advocated if oral intake is inadequate causing poor weight gain or when there is significant aspiration during feeding, or if feeding is very distressing. To find out if caregivers were happy with the outcome of gastrostomy (with fundoplication, when indicated), a 35-item questionnaire was developed and sent to 38 of them. Twenty-nine replies were received and appeared to be representative of the whole group. Coughing, choking, and vomiting improved in most cases. Weight gain improved in all in whom it had been a problem. In the majority, it became easier to give the children their medications although control of epilepsy was unchanged overall. Time spent feeding the child was reduced and many caregivers had more time to devote to other children and themselves. Only one parent regretted the operation. In children with severe disability and feeding problems, a gastrostomy (with fundoplication if there is significant reflux) can reduce symptoms of vomiting, coughing, and choking, help growth and improve quality of life in the child, when patients are properly selected.
