Article Synopsis
  • The management of blunt splenic trauma differs between children and adults, influenced by guidelines from organizations like the APSA and WTA, particularly regarding treatment methods like splenectomy and angioembolization.* -
  • A comparison of the 2023 guidelines revealed that while initial resuscitation is standard, the management strategies diverge: adults' care is guided by both CT findings and hemodynamic status, while children's care relies solely on hemodynamics.* -
  • Differences in ICU admission, follow-up protocols, and thromoprophylaxis use highlight the distinct approaches for each age group, suggesting a need for unified guidelines that cater to the specific needs of both children and adults.*

Introduction: Keeping children nil by mouth until return of bowel function after intestinal anastomosis surgery is said to reduce complications. Fasting may extend up to five days, risking malnourishment and usage of parenteral nutrition. This study aims to establish the efficacy and safety of early enteral nutrition in children undergoing intestinal stoma closure.

This review describes the sonographic appearances of the neonatal bowel in Necrotising enterocolitis. It compares these findings to those seen in midgut-Volvulus, obstructive intestinal conditions such as milk-curd obstruction, and slow gut motility in preterm infants on continuous positive airway pressure (CPAP)-CPAP belly syndrome. Point-of-care bowel ultrasound is also helpful in ruling out severe and active intestinal conditions, reassuring clinicians when the diagnosis is unclear in a non-specific clinical presentation where NEC cannot be excluded.

Background: Abdominal compartment syndrome (ACS) is a pathological increase of the intra-abdominal pressure (IAP) with dysfunction of one or more organs. There is lack of clarity in neonates regarding what intravesical pressure (IVP) value, a surrogate marker for IAP, indicates the need for intervention for ACS.

Methods: The medical records at a Children's Hospital NICU were reviewed to identify all neonates that had IVP/s monitored over a 10-year period (2008-2017).

Hirschsprung's disease is characterized by the absence of ganglia in the distal colon, resulting in a functional obstruction. It is managed by excision of the aganglionic segment and anastomosis of the ganglionated bowel just above the dentate line. The level of aganglionosis is determined by performing multiple seromuscular biopsies and/or full thickness biopsy on the antimesenteric border of the bowel to determine the level of pullthrough.

Trauma and injury continue to be common in children and remain an important cause of mortality and morbidity. Legislation mandating the use of helmets for all cyclists appears to have been effective in reducing the incidence and severity of head and facial injuries, with no clear evidence of a reduction in cycling usage or activity. Straddle injuries, whilst uncommon and generally minor, require careful clinical assessment as they may be associated with urethral trauma.

Oesophageal atresia and tracheo-oesophageal fistula are congenital anomalies of the oesophagus requiring surgical repair in infancy, either by open or thoracoscopic approach. Although mortality rates associated with this procedure are low, children may go on to have complications throughout childhood and into adulthood, most commonly related to ongoing gastrointestinal and respiratory symptoms. This review outlines the early, mid and long-term outcomes for these children in terms of quality of life and incidence of symptoms.
