Severe acute respiratory syndrome (SARS) is an emerging infectious disease. After the appearance of an index patient in Hong Kong in February 2003, SARS outbreaks occurred rapidly in hospitals and spread to the community. The aim of this retrospective study is to evaluate the effectiveness of a triage policy and risk-stratified infection control measures in(More)
Paediatric brain tumours commonly arise in the posterior cranial fossa. Early diagnosis is often challenging due to initial non-specific clinical symptoms, especially in very young children. The typical MR features of tumours in this region including medulloblastoma, ependymoma, juvenile pilocytic subtype of cerebellar astrocytoma, brain stem glioma and(More)
Primitive neuroectodermal tumours (PNETs) constitute a family of neoplasms of presumed neuroectodermal origin that predominantly present as bone or soft-tissue masses in adolescents and young adults. PNET arising in the kidney is rare. To describe the radiological features in three patients with primary renal PNET. The radiological features of primary renal(More)
OBJECTIVE To evaluate the initial presenting symptoms and management of osteosarcoma in Hong Kong Chinese children, in relation to any possible impact on disease outcomes. DESIGN Retrospective study. SETTING A tertiary referral centre of bone cancer in a university teaching hospital in Hong Kong. PATIENTS All children aged younger than 18 years with a(More)
The objective of this work is to describe the imaging findings, clinical profile and treatment response in four Chinese adolescent patients presenting with ectopic germinoma arising from basal ganglia. The clinical presentation, treatment regimens and the imaging findings at presentation and after treatment were described upon retrospective review of four(More)
Here we report a familial cluster of 3 cases of coxsackievirus B3 infection: a recent history of illness in a woman's 3-year-old son with a coxsackievirus B3-positive stool culture indicated that he probably infected his mother at home during her last week of pregnancy. Consequently, she delivered an infected neonate who developed severe hepatitis,(More)
The clinical, laboratory, and radiological features at presentation of 16 children (<12 years) with severe acute respiratory syndrome (SARS) and pneumonia were compared with 32 age matched patients with community acquired pneumonia for determination of predictive factors that could allow early differentiation of the two conditions. A definitive contact(More)
BACKGROUND The progression to disseminated intravascular coagulation (DIC) in infected very low birth weight (VLBW; <1500 g) infants is difficult to predict with precision at the onset of sepsis. We investigated the immunologic profiles of preterm infants with sepsis, using chemokine and cytokine measurements to predict the development of sepsis-induced DIC(More)
Neoplastic abdominal tumours, particularly those originating from embryonal tissue (such as hepatoblastoma and nephroblastoma) and neural crest cells (such as neuroblastoma), are well-documented in young children. Neoplasms of adulthood, most commonly carcinoma of different visceral organs, are also well-documented. Abdominal tumours in adolescence(More)
The Severe Acute Respiratory Syndrome (SARS) is a newly discovered infectious disease caused by a novel coronavirus, which can readily spread in the healthcare setting. A recent community outbreak in Hong Kong infected a significant number of pregnant women who subsequently required emergency caesarean section for deteriorating maternal condition and(More)
