UNLABELLED Congenital giant ranula causing life-threatening upper airway obstruction is a rare condition. A well-planned ex utero intrapartum treatment (EXIT) procedure for aspiration and decompression of the cystic lesion is simple, efficacious and effective in securing a patent airway before the fetus is completely delivered, and may prevent lifelong(More)
BACKGROUND Childhood obstructive sleep apnoea (OSA) is suggested to be associated with cardiac structural abnormalities and dysfunction but existing evidence is limited and the treatment effect on echocardiographic outcome remains controversial. OBJECTIVE To examine the presence of subclinical cardiac abnormalities in childhood OSA and the effects of(More)
OBJECTIVE To determine the prevalence and risk factors of obstructive sleep apnoea syndrome (OSAS) in Chinese children using a two-phase community-based study design. METHODS Children from 13 primary schools were randomly recruited. A validated OSAS screening questionnaire was completed by their parents. Children at high risk of OSAS and a randomly chosen(More)

This paper explores the mechanism(s) whereby liposomes accumulate in chronically ischaemic myocardium and intestine. Plasma prepared from venous blood obtained at sites of myocardial and intestinal infarction does not promote the lysis of positively and negatively charged liposomes in vitro. Albumin-bound lysophosphatidylcholine (greater than or equal to 2(More)
