Long-term outcome following pediatric liver transplantation for metabolic disorders. Pediatr Transplant 2010:14:268,275. © 2009 John Wiley & Sons, A/S. Abstract:, In order to determine long-term outcome, including survival, growth and development, following liver transplantation in children with metabolic disorders, we retrospectively reviewed charts of 54 children with metabolic disorders evaluated from 1989,2005 for presenting symptoms, transplantation timing and indications, survival, metabolic parameters, growth, and development. Thirty-three patients underwent liver transplantation (12 received combined liver,kidney transplants) at a median age of 21 months. At a median follow-up of 3.6 yr, patient survival was 100%, and liver and kidney allograft survival was 92%, and 100%, respectively. For the group as a whole, weight Z scores improved and body mass index at follow-up was in the normal range. Two yr post-transplantation, psychomotor development improved significantly (p < 0.01), but mental skills did not; however, both indices were in the low-normal range of development. When compared to patients with biliary atresia, children with metabolic disorders showed significantly lower mental developmental scores at one and two yr post-transplantation (p < 0.05), but psychomotor developmental scores were not significantly different. We conclude that, in patients with metabolic disorders meeting indications for transplantation, liver transplantation or combined liver,kidney transplantation (for those with accompanying renal failure) is associated with excellent long-term survival, improved growth, and improved psychomotor development. [source] Growth curves of pediatric patients with biliary atresia following living donor liver transplantation: Factors that influence post-transplantation growthPEDIATRIC TRANSPLANTATION, Issue 7 2007Takeshi Saito Abstract:, We evaluated the growth curves of children with BA after LDLT, and identified factors influencing growth velocity one-yr after LDLT (,Z). The clinical data of 51 children with BA, who had an LDLT at our center from 2001 to 2005, were retrospectively reviewed. The Z scores for height and weight, and ,Z were studied. The correlation between ,Z and various clinical factors was evaluated statistically. Multivariate stepwise analyses were performed for ,Z. The average height and weight Z scores at the time of LDLT were ,1.34 ± 1.36 (±s.d.) and ,0.78 ± 1.15, respectively. Among 30 BA recipients with stable liver function after transplant, weight returned to normal one-yr post-transplantation. However, height did not return to normal even by the third post-transplantation year. On multivariate analyses, 73% of the variance in height ,Z could be accounted for by factors such as standardized height at the time of LDLT (proportion of variance: 38%), number of steroid pulse treatments (17%), donor age (10%), and the presence of HVS (9%). Fifty-four percentage of the variance in weight ,Z could be accounted for by factors such as standardized weight at the time of LDLT (37%) and the total steroid dose given (17%). Height and weight status at the time of LDLT likely have the strongest impact on ,Z. Additional factors include steroid exposure, age of the living donor, and presence of HVS, all of which should be considered to improve post-transplantation growth. [source] Growth of children on the ketogenic dietDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 12 2002Eileen P G Vining MD This is a prospective cohort study of 237 children (130 males, 107 females) placed on the ketogenic diet for control of intractable epilepsy (mean age at starting diet 3 years 8 months; age range 2 months to 9 years 10 months); average length of follow-up was 308 days. There were 133 children on the diet at 1 year and 76 at 2 years. Height and weight measurements were converted into age- and sex-appropriate z scores. There was a rapid drop in weight z scores in the first 3 months. After this initial period, the weight z score remained constant in children who started the diet below the median weight for their age and sex, although z scores continued to decrease in children starting above the median. There was a small decrease in height z scores in the first 6 months (<0.5); however, there were larger changes by 2 years. There was no difference based on sex for either height or weight. The ketogenic diet generally provides sufficient nutrition to maintain growth within normal parameters over a defined period. Very young children grow poorly on the diet and should be followed-up carefully over long periods of use. [source] Working conditions and health status of child workers: Cross-sectional study of the students at an apprenticeship school in KocaeliPEDIATRICS INTERNATIONAL, Issue 1 2010Cigdem Caglayan Abstract Background:, Child labor remains a widespread phenomenon in today's world. The purpose of the present study was to describe the working conditions and health status of child workers in Kocaeli. Methods:, A cross-sectional research study has been carried out on 365 working children at the Kocaeli Occupational Training Center. Data were collected on working conditions, smoking habits, work accidents, perceived health status and psychological status using General Health Questionnaire-12. In order to evaluate the physical growth of children, their height and weight were measured. Results:, Most working children usually have a low level of education, low income and extended families. The mean age for children to start working was 14.8 ± 1.5 years and their daily working periods were 11.3 ± 1.3 h on average. Girls were found to have more psychopathology compared to boys on the GHQ-12 and the results were statistically significant. The height z score was less than ,2 SD at 6.9% while the weight z score was less than ,2 SD at 1.9%. According to body mass index (BMI) percentiles range, 3% of children were found to be underweight. A statistically significant and negative directional correlation was detected between body mass index z scores with age and daily working periods. Statistically significant but weak correlations were detected between height for age z scores and the starting age of work and also between weight for age z scores and chronological age. Conclusions:, Both the mental and the physical health of children were found to be negatively affected, by having to work at an early age, and by long working hours. For this reason, immediate and direct intervention should be taken to eradicate child labor, and protect children from unsafe and exploitative working conditions.
