Recurrent intussusception in infants.

Aim: Clinical features to identify infants at increased risk of recurrence after a primary episode of intussusception (IS) are poorly defined.

Methods: Prospective study of the clinical presentation, treatment and outcome in infants <2 years presenting with acute IS to the National Hospital of Pediatrics, Hanoi, over a 14-month period (1 November 2002 to 31 December 2003). A retrospective review of medical records was performed to verify complete patient ascertainment.

Accuracy of ultrasonography for the diagnosis of intussusception in infants in Vietnam.

Background: Intussusception (IS) is the most common cause of acute bowel obstruction in infants and young children. Ultrasonography is being increasingly used as the primary investigation for the diagnosis of IS and to guide air or hydrostatic enema reduction. However the accuracy of ultrasonography outside tertiary care settings in developed countries has not been assessed, particularly in Asia where the incidence of IS based on sonographic diagnosis has been reported as the highest in the world.

Risk factors for intussusception in infants in Vietnam and Australia: adenovirus implicated, but not rotavirus.

Objective: This study aimed to investigate risk factors for the development of intussusception in infants in a developing country with a suspected high incidence and in a developed country with a low incidence.

Study Design: A prospective case-control study of infants <2 years of age with idiopathic intussusception confirmed by air enema or surgery was conducted at the National Hospital of Paediatrics (NHP), Vietnam (n = 533) and the Royal Children's Hospital (RCH), Australia (n = 51). Diagnosis was validated in a subset (84% NHP; 67% RCH) by an independent blinded radiologist.

Intussusception: trends in clinical presentation and management.

Background: The association of a rotavirus vaccine and intussusception has renewed interest in understanding the incidence, clinical presentation and outcome of intussusception.

Methods: A retrospective chart review of all patients diagnosed with intussusception at Royal Children's Hospital, Melbourne over a 6.5-year period (1 January 1995-30 June 2001) was conducted using patients identified by a medical record database (ICD-9-CM code 560.
