Pacing experience with the atrial screw-in leads at the Singapore General Hospital.
This is a retrospective study of atrial screw-in leads implanted at the Singapore General Hospital from January 1988 to August 1990. There were 21 (13 female and 8 male) consecutive patients, with age ranging from 17 to 79 years (mean 55 years). Thirteen patients had sick sinus syndrome and the remaining eight patients had high grade AV block. ⋯ On follow-up ranging from one month to two years, two patients had inadequate sensing in the atrium and one patient had high pacing threshold. There were no lead dislodgement. In conclusion, these screw-in leads can be safely used in the atrium with acceptable pacing characteristics.

Intraoperative anaesthetic management of the liver transplant patient.
Orthotopic liver transplantation has become an established method of treating end-stage liver disease. Anaesthesia for patients undergoing this procedure can be complicated because end-stage liver disease is often associated with dysfunction of other physiological systems. ⋯ The increased understanding of the pathophysiology of the procedure and the use of dedicated rapid infusion systems and intraoperative blood salvage have helped to improve the intraoperative management of the liver transplant patient. Co-operation and communication between the blood bank, haematology, biochemistry, surgical and anaesthesia services are vital.

Randomized Controlled Trial Clinical TrialCetirizine vs placebo in chronic idiopathic urticaria--a double blind randomised cross-over study.
The efficacy of cetirizine dihydrochloride, a new H1-antagonist claimed to have minimal sedative property was evaluated in 28 patients with chronic idiopathic urticaria. Cetirizine 10 mg and placebo were compared in a double-blind cross-over trial. Response was measured by patients with daily charts on itch and wheals. ⋯ Five of the 28 (17.9%) patients reported mild drowsiness while taking cetirizine. Two patients reported drowsiness while on placebo. Tolerance was reported as good in 85%, moderate in 10% and bad in 5% according to patients' assessment, while tolerance was excellent and good in 80%, moderate in 15% of patients according to investigator's assessment.

Episodic headaches associated with ocular symptoms is a frequent complaint in clinical practice. In the medical and medical related field of neurology, one of the most often considered diagnosis is that of classical migraine, whilst in ophthalmology, the condition of intermittent primary angle closure glaucoma must be entertained. This paper reports three cases in which the two conditions were confused, and follows with a discussion on the essential differentiating features that can help in the diagnosis.

Hypertext-based enhancement of medical and dental undergraduate learning.
The use of the microcomputer in medical education began about 1977. Since then man computer-assisted learning packages have been developed for preclinical and clinical subjects. ⋯ Elementary levels of animation can also be achieved. In this way it illustrates how a study of Anatomy, for example, can be made using the computer to "dissect" the human body.
