A child’s esophagus can
become damaged through physical trauma or ingestion of toxic chemicals or
foreign objects — such as oven and drain cleaners, lye, laundry and dishwasher
detergents and batteries. Depending on the substance and the amount ingested,
children can develop esophageal strictures (scar tissue that narrows the esophagus) or esophageal perforations (holes in the
esophagus). These problems can also be complications of surgery for esophageal atresia, in which a baby is born without part of the esophagus.
Children with esophageal perforations have traditionally been treated with long courses of antibiotics and not eating by mouth. More recently, perforations have been treated with stents, and strictures with a combination of dilation and stenting. But stenting, while it can be effective, requires up to eight weeks of therapy and can have complications such as pain, retching and local pressure necrosis, a type of ulcer that may worsen perforation. Such concerns have led researchers to investigate alternative treatments for perforation and strictures.
Almost 10 percent of pediatric deaths occur suddenly and without explanation. In this terrible situation, the first question many parents have is “Why?” For most, answers never come.
Childhood deaths that cannot be explained by traditional autopsy and death-scene investigation are referred to as sudden unexplained deaths in pediatrics (SUDP). In children, these deaths are more common than those from either cardiac disease or cancer and typically occur in infancy or early childhood.
An estimated 8 million children worldwide live in institutions where they experience neglect and deprivation. Last fall, a study of children reared in Romanian orphanages reported high levels of mental health problems when they reached adolescence. In particular, they had more difficult behaviors such as rule-breaking, excessive arguing with authority figures, stealing or assaulting peers. But if they were placed early with carefully vetted foster families through the Bucharest Early Intervention Project (BEIP) , these problems were reduced.
A new BEIP study, published yesterday in the Proceedings of the National Academy of Sciences, examined cognitive functioning. It found that institutionalized children, at ages 8 and 16, also have impaired memory and executive functioning compared with peers placed early in foster homes. …
But Stegmaier is also interested in epigenetic regulators — proteins that help control the regulation of genes and contribute to many pediatric cancers. They’re a hot subject of research: Child cancers tend to arise in developing tissues, and epigenetic regulators are active during early development. Clinical trials are starting to test drugs that inhibit epigenetic cancer-promoting factors.
There’s a problem, though: Cancers often become resistant to targeted inhibitors, including epigenetic inhibitors. So, again using genome-wide approaches, Stegmaier set out to find ways to overcome this resistance. …
Every year, nearly 400,000 children worldwide develop hydrocephalus, in which excess fluid accumulates in the brain. Many of these children have shunts placed to allow this fluid to drain. Antibiotic-impregnated shunts are widely championed as the best choice for treatment, but a new study calls their necessity into question. …
The FDA requires clinical studies of new drugs in pediatric populations, since many drugs developed for use in adults are also used in children. These studies are often “post-marketing” trials after the drug is approved in adults. But an audit by researchers at Boston Children’s Hospital found that only about a third of these mandatory trials were completed within an average of seven years. As a result, most new drug labels continue to lack child-specific information, and most FDA-approved drugs remain untested in children. …
Ed. note: This is an update of a post that originally appeared in 2014.
The neural tube is supposed to close during the first month of prenatal development, forming the spinal cord and the brain. In children with spina bifida, it doesn’t close completely, leaving the nerves of the spinal cord exposed and subject to damage. The most common and serious form of spina bifida, myelomeningocele, sets a child up for lifelong disability, causing complications such as hydrocephalus, leg paralysis, and loss of bladder and bowel control.
A growing body of research from Boston Children’s Hospital, though still in animal models, suggests that spina bifida could be repaired at least partially early in pregnancy, through intrauterine injections of a baby’s own cells. …
A new study adds to growing concerns about a class of drugs frequently prescribed to suppress stomach acid in patients with gastroesophageal reflux disease (GERD). Previous research has linked the use of proton pump inhibitors (PPIs) to an increased risk of various pulmonary and gastrointestinal infections in both adults and children. Patients treated with PPIs are also at higher risk for upper respiratory infections, pneumonia and sepsis.
The idea of genomic sequencing for every newborn has many in the scientific community buzzing with excitement, while leaving others wary of the ethical and social implications. But what do the parents think? The BabySeq Project has been exploring parental motivations and concerns while assessing their willingness to participate in a pilot newborn sequencing study. …
