Malignant phaeochromocytoma is defined as the presence of tumour deposits at sites that are normally devoid of chromaffin cells. We report on a 63-year-old man who had a giant malignant phaeochromocytoma of the right adrenal gland that encased the inferior vena cava. The urinary excretion rates of catecholamines and their metabolites were normal, except for normetanephrine, which was excreted at a higher rate than normal. The tumour was surgically unresectable by laparotomy. Postoperatively, the patient was given a 4-month trial of subcutaneous octreotide and intravenous meta-iodobenzylguanidine I 131. Occult lung secondary tumours were first detected by meta-iodobenzylguanidine scintigraphy after 2 years, and the patient died of bone and lung metastases 1 year later. Because phaeochromocytoma is rare, local experience in managing this disease is limited. This report alerts physicians of the methods of diagnosing and managing surgically unresectable malignant phaeochromocytoma.

Long and pointed foreign objects in the stomach are difficult to remove by endoscopy, and they can cause complications such as perforation and impaction. The endoscopic removal of long and pointed objects involves the following principles: (1) presenting the blunt end cephalad to prevent perforation or impaction during extraction; (2) orienting the long axis of the object in the line of extraction; and (3) applying traction to the foreign body without losing grip. Currently practised methods of extraction, which use a protector hood or an overtube, do not address these three principles. We report on a case in which an ingested metal dinner fork was removed from the stomach by using a double wire-loop snare technique. This method uses two snares to hold the object and allows the endoscopist to change the presentation, orient the axis, and maintain traction to allow the safe removal of long and pointed objects.

Fungal infection of bone by Penicillium marneffei is rare. We report on a case of Penicillium marneffei infection in a Filipino woman, which involved multiple soft-tissue abscesses and infection of the axial skeleton. Early diagnosis and treatment of this potentially reversible disease is emphasised. Such an approach is essential to prevent bony destruction from becoming too advanced and, more importantly, to prevent any damage to the spinal cord from occurring.

We report on a case of facial nerve palsy associated with Kawasaki disease in a 2-year-old boy. Facial nerve palsy is one of the rare neurological manifestations of Kawasaki disease. Twenty-seven other cases that have been reported in the literature are reviewed. There is a high incidence of coronary artery aneurysm (52%) and a female predilection in patients with Kawasaki disease. The facial palsy associated with the disease is self-limiting. Recovery is spontaneous in surviving patients, although the use of intravenous immunoglobulin may be able to hasten the recovery.

We report on a 12-year-old boy with herpes simplex encephalitis, in whom a severe localised skin reaction developed following the infusion of intravenous acyclovir. Oral valaciclovir was given as continuation therapy to complete the 3-week course of antiviral treatment and resulted in complete recovery without side effects. This report illustrates the advantage of using the polymerase chain reaction to diagnose herpes simplex encephalitis and the potential use of newer antiviral agents, such as valaciclovir, as continuation therapy in the management of the infection. The higher oral bioavailability of newer antiviral agents allows part of the extended treatment period of patients with herpes simplex encephalitis to be carried out as an ambulatory oral regimen.
