How do parents of 4‐ to 5‐year‐old children perceive the weight of their children?

Introduction: A heavier weight in adults is becoming the norm rather than an abnormal weight. Whether the same trend is happening in children is unknown. Objective: To assess the perception of the weight of 4‐ to 5‐year‐old children and the recognition of overweight by both parents. Design: Population‐based survey. Participants: A questionnaire was sent to parents of 1155 4‐ to 5‐year‐old children. Results: In total, 439 questionnaires (35%) were returned. Of all, 90% of the children had a normal weight, 9.3% were overweight and 4.1% were obese. For all weight classes, the parents depicted the child as lighter on both the verbal and visual scale. Of all, 75% of mothers of overweight children stated that the child had a normal weight. In obese children, 50% of the mothers believed that the child had a normal weight. Conclusion: Children with a weight in the normal range were considered by their parents as a little too light or too light. Overweight was considered as normal weight, and obesity as normal or a little too heavy. The perception of a normal weight in children at 4–5 years is distorted.     

Early assessment and neurodevelopmental outcome in very low-birth-weight infants: implications for pediatric practice

To determine which assessments are useful, at what age, in order to identify handicaps in very Iow-birth-weight infants, neonatal cerebral ultrasound findings, neurological examinations and the mental scale of the Bayley Infant Scales of Development at 1 and 2 years of age were examined in relation to neurodevelopmental outcome at 3.6 years of age in a cohort of 79 high-risk very low-birth-weight infants. At 3.6 years of age, a minor handicap was found in 9 (11%) and a major handicap in 4 (5%) children. Cerebral palsy was found in 9 (11%) children at 3.6 years of age and could only be diagnosed reliably at 2 years of age. For short-term follow-up, as feedback to the neonatalogist, the positive predictive value of intraparenchymal damage, as detected by neonatal cerebral ultrasound, was greater than the positive predictive value of a definitely abnormal neurological examination at 1 year of age. Visual handicaps ( n = 4, 5%) and severe hearing deficits ( n = 1, 1 %) were all detected in the first year of life. A mental handicap was found in 7 (9%) children. It was impossible to predict mental handicaps for the individual child. Only 35% of the children with a mental delay at 2 years of age had a mental handicap at 3.6 years of age, whereas 35% had a normal cognitive outcome. Pediatricians therefore should be cautious in the interpretation of developmental tcst results in infancy. Long-term follow-up is essential for the child and its parents.     

Substrate utilization during the first weeks of life

It is assumed that substrate utilization changes markedly around birth, from mainly glucose utilization before, to glucose/fat utilization after birth. We studied substrate oxidation and turnover in preterm infants on the first day and during the first weeks of life. We found that only part of the glucose that is infused on the first day of life is oxidized, while glucose is also converted into fat at the same time. Almost half of the energy expenditure is provided by fat oxidation on day 7 and 28 of life. Fat oxidation is dependent on the type of fat oxidized; the rate of oxidation of medium chain triglycerides (MCT) is higher than that of long chain fatty acids. MCT can replace glucose as an energy source. Proteins contribute only to a small extent (approximately 7%) to the energy expenditure at all ages.     

COX-2 inhibition improves immunotherapy and is associated with decreased numbers of myeloid-derived suppressor cells in mesothelioma. Celecoxib influences MDSC function

Background  

Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of immature cells that accumulates in tumour-bearing hosts. These cells are induced by tumour-derived factors (e.g. prostaglandins) and have a critical role in immune suppression. MDSC suppress T and NK cell function via increased expression of arginase I and production of reactive oxygen species (ROS) and nitric oxide (NO). Immune suppression by MDSC was found to be one of the main factors for immunotherapy insufficiency. Here we investigate if the in vivo immunoregulatory function of MDSC can be reversed by inhibiting prostaglandin synthesis by specific COX-2 inhibition focussing on ROS production by MDSC subtypes. In addition, we determined if dietary celecoxib treatment leads to refinement of immunotherapeutic strategies.     

Fibrin glue obliteration is safe,effective and minimally invasive as first line treatment for pilonidal sinus disease in children

Background / PurposeSacrococcygeal pilonidal sinus disease (PSD) has an incidence of 1.2–2.5/1000 in children. Onset is around puberty. Symptoms of recurrent abscess and chronic suppuration may interfere with education and social integration. Treatments should cause minimal disruption while having good cure and recurrence rates. Curettage and Fibrin glue obliteration (FGO) show promising results in adults. We present our experience of its use in children.MethodsReview of all pediatric patients receiving FGO of pilonidal sinus performed by a single surgeon from September 2014 to February 2018.ResultsEighteen patients were identified. Median age was 16 (range 15–17), 55.6% were male. All procedures were completed as day cases. Median operative duration was 14 .1 (6–29) min. Twelve patients required only 1 procedure, 4 required 2 procedures, 1 required 5 procedures and 1 elected for formal excision after 2 FGO treatments. Median return to normal activities was 3 days, with 1 day school absence. Two patients developed minor surgical site infections. Median follow-up was 52 weeks (17–102), during which time there was 1 recurrence (5.6%).ConclusionThis study demonstrates FGO is a safe, effective procedure for pediatric PNS, with results comparable to off-midline flap techniques and without the need for extensive tissue excision and the associated morbidity.Level of evidenceIV
