Keloids and hypertrophic scars are abnormalities in the normal wound healing characterized by greater and more sustained extracellular matrix deposition that develops after any insult in the dermis.
It can affect the patient's quality of life, both physically and psychologically.
Hypertrophic scars are raised fibrous tissue scars that remains within the boundaries of the wound. Hypertrophic scars that resulted from surgery or trauma are called linear hypertrophic scars while those from burn injuries or extensive tissue trauma and/or infections are called widespread hypertrophic scars.
Keloids are elevated fibrous scars that extend beyond the borders of the original wound. Major keloids resulted from minor trauma while for those from genetic predisposition with autosomal-predominant features are called minor keloids.

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.
Spending too much time sitting cannot be good for the body, and rising to one's feet breaks up such a behaviour and yields small, but meaningful, reductions in certain cardiovascular disease (CVD) risk factors, according to the results of a meta-analysis.
