Tailoring of recommendations to reduce serious cutaneous adverse drug reactions: a pharmacogenomics approach.

The Health Sciences Authority launched a pharmacogenetics initiative in 2008 to facilitate evaluation of pharmacogenetics associations pertinent for Chinese, Malays and Indians in Singapore. The aim was to reduce the incidence and unpredictability of serious adverse drug reactions, with a focus on serious skin adverse drug reactions. This paper describes the gathering of evidence and weighing of factors that led to different genotyping recommendations for HLA-B*15:02 with carbamazepine and HLA-B*58:01 with allopurinol, despite both having strong genetic associations.

A review of perioperative anaphylaxis at a Singapore tertiary hospital.

Introduction: Perioperative anaphylaxis is an anaesthetic emergency, but its incidence is not well described in the local literature. This retrospective study aims to look at a group of patients who had perioperative anaphylaxis in our institution.

Methods: We conducted a retrospective review of electronic databases and clinical case sheets, and identified 34 patients who had possible perioperative anaphylaxis during anaesthesia in our institution between 1 January 2007 and 30 April 2012.

Disease patterns of rheumatology outpatients seen in a tertiary hospital serving a multi-ethnic, urban Asian population in Singapore.

Aims: To describe the spectrum of diseases seen in an outpatient setting in the Singapore General Hospital, the largest tertiary referral centre in Singapore.

Methods: In this cross-sectional study, medical records of patients scheduled for an appointment at the rheumatology specialist outpatient clinics over a 4-month period (10 August 2010-31 December 2010) were reviewed. Primary diagnoses documented by the attending physician at the latest visit were recorded.

Clinical aspects and management of fibromyalgia syndrome.

Fibromyalgia syndrome (FMS) is a chronic and debilitating musculoskeletal pain disorder of unknown aetiology with usual accompanying features of fatigue, sleep disturbances and stiffness. Its place in medical textbooks was controversial with rheumatologists holding the helm of its management for many years. Over the last decade, abnormalities have been identified at multiple levels in the peripheral, central, and sympathetic nervous systems as well as the hypothalomo-pituitary-adrenal axis stress response system.

The value of joint aspirations in the diagnosis and management of arthritis in a hospital-based rheumatology service.

Introduction: Although joint aspiration with synovial fluid analysis is useful in the diagnosis of crystal or septic arthritis, the frequency with which it provides a diagnosis or aids subsequent management of patients with arthritis has not been well quantified. We therefore evaluated the usefulness of joint aspiration in the diagnosis and management of patients with arthritis in a hospital-based rheumatology service.

Materials And Methods: We reviewed records of all patients with joint aspiration performed by an inpatient rheumatology service in a tertiary referral hospital from November 2003 to December 2004.
