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.
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.
Tissue expanders — small balloons that can be filled with saline solution or other fluids to grow skin — have long been used in plastic surgery, most commonly breast reconstruction. They’re based on the simple idea that the surrounding skin will stretch as the device expands over time. That extra skin can then help repair injuries or congenital anomalies or accommodate implants.
Midaortic syndrome occurs when the middle section of the aorta is narrowed and typically affects children and young adults. It can cause severe hypertension and can be life-threatening if left untreated. The surgical approach to this condition would be to replace the damaged portion of the aorta with nearby healthy blood vessels. However, this usually isn’t possible because these vessels tend to be too short to adequately fill in. …
By the time he arrived at Boston Children’s Hospital, the 6-month-old boy was near death from midaortic syndrome — a rare but life-threatening condition marked by narrowing of the middle section of the aorta, the largest artery in the body. It had left him with severe hypertension, acute kidney injury and heart failure. As cardiologists worked to stabilize him, the surgical team weighed the options.
With diminished blood flow to the chest, abdomen and lower limbs, a significant number of people with untreated midaortic syndrome die from complications by age 40. The condition can be treated surgically, traditionally with a prosthetic graft made from synthetic material to perform an aortic bypass. But synthetic grafts can pose a number of challenges in children.
“Synthetic grafts don’t grow with the patient, which means that multiple surgeries may be necessary through the years to ensure appropriate graft size,” explains nephrologist Michael Ferguson, MD, who was a member of this patient’s care team. “Artificial grafts also carry a higher risk of thrombosis and infection.” …
Head shaved, a little boy rests on the operating table, deep under anesthesia. His parents have brought him to Boston Children’s Hospital in hopes of determining the cause of his seizures. Now, neurosurgeons Scellig Stone, MD, PhD, Joseph Madsen, MD, and their colleagues in the Epilepsy Center are performing a procedure designed to monitor seizure activity in the 3-year-old’s brain.
But as the team members crowd around the table, they’re not alone. With the push of a button, a large robotic arm rotates and lowers right next to the boy’s head, helping the physicians pinpoint the precise location to drill. “This is a real game-changer,” murmurs one of the clinicians observing the surgery. “It’s going to transform the way we practice.” …
Could an exciting potential treatment for inflammatory bowel disease (IBD) be found in the gastrointestinal tract itself? That’s the theory behind a pair of new studies by Stacy A. Kahn, MD, which will investigate the potential role of fecal microbial transplant (FMT) in the treatment of Crohn’s disease and ulcerative colitis in children.
In IBD, the immune system attacks healthy cells in the digestive tract, triggering symptoms such as abdominal pain, fatigue, poor growth and bloody diarrhea. Children with IBD can also experience problems elsewhere in the body, including joint pain, liver disorders and eye inflammation.
Known colloquially as the “poop pill,” or “stool transplant,” FMT harnesses growing knowledge about the gut microbiota, the collection of bacteria and other microbes that populate our GI tract. …
