Introduction: Ischaemic stroke is a severe complication of dermal filler injections that remains poorly described and understood. This study aims to characterise the clinical features and outcomes of patients who experience strokes following facial dermal filler injections.

Method: A systematic review and retrospective analysis of ischaemic strokes caused by dermal filler injections and reported over the past 3 decades, were conducted. Cases involving autologous fat were also compared against those that did not.

Results: Fifty-five cases from 45 studies were analysed. Their median age was 32 years (18-61), and most were women (49/55, 89%). Injections frequently occurred at the glabella (17/53, 32%) and temples (12/53, 23%), and autologous fat was most often used (33/55, 60%). Half (29/55, 53%) had ocular symptoms at presentation. Hemiparesis/hemiplegia (30/55, 55%) and confusion/ reduced consciousness/alertness (26/55, 47%) were the predominant stroke symptoms. Most infarcts were unilateral (45/54, 83%) and large (32/48, 67%). Treatment primarily involved corticosteroids (12/41, 29%) and antiplatelet agents (11/41, 27%), while hyaluronidase injections (3/41, 7%) and hyperbaric oxygen therapy (2/41, 5%) were rarely used. Less than half (22/55, 40%) experienced good functional recovery. Those injected with autologous fat were likelier to be symptomatic from their strokes (100% versus [vs] 68%, P=0.0012), develop larger strokes (93% vs 24%, P<0.0001) and experience non-ambulatory outcomes (44% vs 73%, =0.0381).

Conclusion: Strokes are rare complications of dermal fillers. Injections using autologous fat risk larger strokes and worse ambulatory outcomes. An hour of post-procedural observation appears reasonable, and those with ocular complications should undergo brain imaging even in the absence of stroke symptoms.

Introduction: Obstructive sleep apnoea (OSA) is common in Singapore, with moderate to severe OSA affecting around 30% of residents. These consensus statements aim to provide scientifically grounded recommendations for the management of OSA, standar-dise the management of OSA in Singapore and promote multidisciplinary collaboration.

Method: An expert panel, which was convened in 2024, identified several areas of OSA management that require guidance. The expert panel reviewed the current literature and developed consensus statements, which were later independently voted on using a 3-point Likert scale (agree, neutral or disagree). Consensus (total ratings of agree and neutral) was set a priori at ≥80% agreement. Any statement not reaching consensus was excluded.

Results: The final consensus included 49 statements that provide guidance on the screening, diagnosis and management of adults with OSA. Additionally, 23 statements on the screening, diagnosis and management of paediatric OSA achieved consensus. These 72 consensus statements considered not only the latest clinical evidence but also the benefits and harms, resource implications, feasibility, acceptability and equity impact of the recommendations.

Conclusion: The statements presented in this paper aim to guide clinicians based on the most updated evidence and collective expert opinion from sleep specialists in Singapore. These recommendations should augment clinical judgement rather than replace it. Management decisions should be individualised, taking into account the patient's clinical characteristics, as well as patient and caregiver concerns and preferences.

Introduction: Endometriosis (EMS) is a common gynaecological disorder linked to metabolic disturbances. However, evidence on the associations between lipid accumulation product (LAP) and visceral adiposity index (VAI) with the risk of EMS remains limited. This study aimed to explore the potential associations between LAP, VAI and EMS.

Method: Data were obtained from the 1999-2006 National Health and Nutrition Examination Survey (NHANES), including a total of 2046 samples. Weighted multivariable logistic regression models and smoothed curve fitting were used to assess the associations between LAP, VAI and EMS. Additionally, subgroup analyses and interaction tests were conducted to evaluate intergroup differences in the associations between LAP, VAI and EMS.

Results: In the fully adjusted model, higher Log2 LAP (odds ratio [OR] 1.256, 95% confidence interval [CI] 1.102-1.431, P=0.0014) and Log2 VAI (OR 1.287, 95% CI 1.105-1.498, P=0.0022) were significantly associated with increased EMS risk. Participants in the highest quartile of Log2 LAP (OR 1.983, P=0.0029) and Log2 VAI (OR 1.690, P=0.0486) had a higher risk of EMS. Subgroup analysis showed stronger associations among women with diabetes (Log2 LAP OR 3.681, P=0.009; Log2 VAI OR 4.849, P=0.041).

Conclusion: Elevated LAP and VAI were independently associated with an increased risk of EMS. LAP and VAI may serve as potential indicators for assessing EMS-related risk, suggesting that visceral obesity and lipid metabolic disturbances might play roles in the pathophysiological process of EMS. These findings underscore the potential of LAP and VAI as non-invasive markers for EMS risk, warranting further validation in clinical settings.
