BACKGROUND A study was undertaken to investigate the relationship between birth anthropometric measures and the subsequent development of asthma, airway hyperresponsiveness, and atopy in later childhood. METHODS A longitudinal study was performed on 734 subjects (71%) from a cohort of children born in Dunedin, New Zealand in 1972-73. The birth(More)
In 2008, propranolol was serendipitously observed to cause accelerated involution of infantile haemangioma. However, the mechanism by which it causes this dramatic effect is unknown, the dosage empirical and the optimal duration of treatment unexplored. This study determines the minimal dosage and duration of propranolol treatment to achieve accelerated(More)
AIMS Propranolol, now the preferred treatment for problematic proliferating infantile haemangioma (IH), at an empirical cardiovascular dosage of 2-3 mg/kg/day is associated with variable complication rates. A meta-analysis shows complications in 31% of patients at a mean dosage of 2.12 mg/kg/day. This study reports on the minimal dosage and duration of(More)
We report here the case of an infant with multiple hepatic and cutaneous infantile hemangiomas (IHs) associated with deranged liver function who was treated successfully with low-dose propranolol. We also discuss our recent data that show that IH is a developmental anomaly of hemogenic endothelium derived from primitive mesoderm with a neural crest-cell(More)
BACKGROUND Recent studies have reported that a large head circumference at birth is associated with an increased risk of raised serum IgE in adult life, and asthma during childhood. OBJECTIVE To examine the relationship between head circumference and other anthropometric measurements at birth and asthma and indices of atopy in childhood. METHODS The(More)
The authors present a case of PHACE(S) (posterior fossa malformations, hemangioma, arterial anomalies, cardiac defects, eye anomalies, and sternal cleft or supraumbilical raphe) syndrome with a right-sided segmental infantile hemangioma, and describe in detail, the associated absent ipsilateral intracranial internal carotid artery and anomalous Circle of(More)
OBJECTIVE To describe the epidemiology of severe rotavirus gastroenteritis and to estimate the hospitalisation rates of this illness in New Zealand children under 3 years of age. METHODS Children under 3 years of age with acute diarrhoea admitted to 1 of 8 study hospitals between 1 May 1998 and 30 April 2000 were surveyed. Their socio-demographic,(More)
AIM To evaluate the effectiveness and the safety of systemic and intralesional steroid therapy for problematic proliferating haemangioma. METHOD 233 patients with haemangioma were identified from our vascular anomalies database 1996-2007. 46 (36%) out of 129 patients with proliferating haemangioma required intervention. 24 of these patients received(More)
BACKGROUND The aetiological factors underlying the worldwide increase in the prevalence of asthma and the international patterns of the prevalence of asthma are not well understood. This has led to consideration of factors such as fetomaternal health which may programme the initial susceptibility to allergic sensitisation, or contribute to the development(More)
AIMS The embryonic-like stem cell origin of infantile hemangioma (IH) and the observed elevated serum levels of alpha-fetoprotein (AFP) in patients with hepatic IH led us to investigate if this tumor was the source of AFP. MATERIALS AND METHODS We measured serial serum levels of AFP in patients with problematic proliferating IH treated with surgical(More)
