Infected ovarian endometrioma: Case series and management outcomes
Illustration by LadyFingers Co.
Dear Editor,
Infected endometrioma, which is the superimposed infection and abscess formation of ovarian endometrioma, is increasingly understood to be a distinct clinical entity from tubo-ovarian abscess (TOA). The pathophysiology of infected endometriosis has been postulated to be a result of endometriotic fluid acting as a culture...

Towards a unified approach: Standardising radiological diagnosis and grading of vertebral compression fractures
Vertebral compression fractures (VCFs) are frequently missed on frontal and lateral chest radiographs.1 Even with abdominal computed tomography, where sagittal imaging is readily available, up to 84% of grades 2–3 compression fractures can be unreported.2 In patients with acute hip fractures, vertebral fractures were found to be unreported in...

Group B Streptococcus screening with antenatal culture and intrapartum polymerase chain reaction: A prospective cohort study
Dear Editor,
Group B Streptococcus (GBS) is a common genital and gastrointestinal tract commensal in healthy women. Vertical transmission of GBS may cause neonatal early-onset GBS disease (EoGBS), and this is prevented by intrapartum antibiotic prophylaxis (IAP) GBS colonisation,1 coupled with long turnaround time of GBS culture, challenges the accuracy...
