Preterm birth (PTB) is birth that occurs before 37 weeks’ gestation, and it is a leading cause of perinatal morbidity and mortality.1 Babies born before 34 weeks’ gestation are particularly associated with high rates of morbidity and mortality.2 They are also at risk of long-term medical and social sequelae.3 It is therefore important to institute preventative measures that can help mitigate the occurrence of PTB in pregnant women.

Bleeding disorders in children can be divided into acquired and congenital conditions, with the acquired being far more common than the congenital. Clinical bleeding manifestations can vary in severity. Identifying the root cause early is crucial to control and halt bleeding as well as to prevent the risk of future bleeding in a vulnerable age group. This can be achieved by a thorough and salient history, physical evaluation, and appropriate investigations. This review will describe the common causes of bleeding disorders in children and will suggest an approach to the workup and diagnosis of such disorders.
Thrombocytopenia, defined as a platelet count of less than 150,000/microL, is clinically suspected when there is a history of increased bruising or bleeding, or when there is petechiae noted which is often referred to as a “rash”. Thrombocytopenia is usually asymptomatic until platelet counts fall below 50,000/microL, and may also be detected incidentally in a full blood count (FBC) during routine evaluation of an asymptomatic patient or during investigations performed for other reasons.1
Chronic hepatitis B virus (HBV) infection is a global problem. Chronic
HBV infection is probably the most common maternal infection encountered
in Hong Kong, China, and Southeast Asia. In Hong Kong, which is one of
the endemic areas, immunisation against HBV was first provided in 1983
to infants born to mothers who were screened positive for hepatitis B
surface antigen (HBsAg). Immunisation became widespread since November
1988, but HBsAg-positive mothers are still encountered frequently.1
