Spondyloarthritis refers to a group of inflammatory diseases characterized by spinal & joint oligoarthritis, enthesitis, and sometimes mucocutaneous, ocular and/or cardiac manifestations.
Ankylosing spondylitis is a prototype of spondyloarthritis, particularly of the axial form.
Diagnosis of ankylosing spondylitis is definite if any of the radiological criterion (grade≥2 bilateral sacroiliitis or grade ≥3 unilateral sacroiliitis) is associated with at least one of the clinical criterion (low back pain & stiffness for >3 months that improves with exercise but not relieved by rest, limitation of motion of the lumbar spine in the sagittal and frontal planes, limitation of chest expansion relative to normal values correlated for age and gender.

Antimicrobial resistance has become increasingly dire as the rapid emergence of drug resistance, especially gram-negative pathogens, has outpaced the development of new antibiotics. At a recent virtual symposium, Dr Hsu Li Yang, Vice Dean (Global Health) and Programme Leader (Infectious Diseases), NUS Saw Swee Hock School of Public Health, presented epidemiological data on multidrug-resistant (MDR) gram-negative bacteria (GNB) in Asia, while Dr Tan Thuan Tong, Head and Senior Consultant, Department of Infectious Diseases, Singapore General Hospital (SGH), focused on the role of ceftazidime-avibactam in MDR GNB infections. Dr Andrea Kwa, Assistant Director of Research, Department of Pharmacy, SGH, joined the panel in an interactive fireside chat, to discuss challenges, practical considerations, and solutions in MDR gram-negative infections. This Pfizer-sponsored symposium was chaired by Dr Ng Shin Yi, Head and Senior Consultant of Surgical Intensive Care, SGH.
