Answers to questions on p 10.

1  Chronic hepatitis B or C infection and liver cirrhosis.

2  Ill-defined upper abdominal pain, weight loss and non-specific malaise. There may be features of underlying cirrhosis.

3  Liver function tests, haemoglobin. Alpha-foetoprotein is helpful if markedly elevated. Ultrasound examination. Imaging by CT or MRI for diagnosis and for staging the tumour. Histological confirmation of all tumours is controversial.

4  Surgical resection or transplantation are the two main options but are suitable for less than 20% of patients with these tumours.

5  Transcatheter arterial chemoembolisation is increasingly used in clinical practice. Other options include intra-arterial or systemic chemotherapy, percutaneous ethanol injection, cryotherapy, thermotherapy, proton or hormonal therapy, or a wide range of their combinations. The current lack of definitive data, however, limits the use of the treatments.

Answers to the questions on p 15

1  Probably women of young and middle age, reflecting the frequency of specific causes such as pregnancy, puerpurium and oral contraceptive use. 2  The extensive presence of collateral circulation explaining some of the pathophysiological differences between venous and arterial stroke. 3  Hereditary prothrombotic disorders together with or without the use of oral contraceptives. 4  Headache, papilloedema, focal deficits, seizures and impaired level of consciousness occur in one-third to three-quarters of patients. 5  MRI combined with MR venogram because it is not only very sensitive but also non-invasive. 6  Patients should receive intravenous heparin guided by close monitoring of the PTT, provided there are no general contraindications to its use. 7  There is no clear correlation between clinical presentation and outcome though rapid onset with coma and focal deficit indicate a poorer prognosis.
