Antimicrobial resistance (AMR) results in drug-resistant infections that are harder to treat, subsequently leading to increased morbidity and mortality. In 2008, we reviewed the problem of AMR in Singapore, limiting our discussion to the human healthcare sector. ⋯ The role of antibiotic use and AMR in food animals and the environment - and the link to human health - is better understood today. This issue of AMR encompasses both human health as well as animal/food safety, and efforts to control it will need to continually evolve to maintain or improve on current gains.

Comparative Study
Hip hemiarthroplasty for femoral neck fractures in end-stage renal disease patients on dialysis compared to patients with late-stage chronic kidney disease.
Hip fractures in patients with end-stage renal disease (ESRD) are associated with frequent complications and poorer outcomes. Patients on chronic dialysis are at additional risk of dialysis-related complications such as myocardial infarction and early osteolysis. We analysed the complications and implant survivorship of hemiarthroplasty in patients with femoral neck fractures with late-stage chronic kidney disease with and without pre-existing dialysis. ⋯ Patients with ESRD on chronic dialysis were more likely to develop cardiopulmonary complications and implant loosening after hemiarthroplasty for femoral neck fractures. Hyperparathyroidism should be optimised, as it may prevent loosening. Our study did not show any difference in complications or outcomes for cemented fixation.

Observational Study
High-sensitivity troponin T and long-term adverse cardiac events among patients presenting with suspected acute coronary syndrome in Singapore.
Prognostic thresholds for 30-day major adverse cardiac events (MACE) have been studied for high-sensitivity troponin T (hsTnT) in patients with suspected acute coronary syndrome (ACS), but there is limited data on the prognostic performance of hsTnT for one-year MACE. ⋯ Patients with 0-, 2- or 7-hour hsTnT ≥ 30 ng/L and 0-2 hour delta-hsTnT ≥ 10 ng/L had PPV > 50% for 30-day and one-year MACE, and should be investigated thoroughly.

A 60-year-old man presented with abdominal pain. He was later diagnosed on imaging to have high-grade small bowel obstruction. ⋯ Small bowel obstruction is a common acute surgical condition with multiple causes, including bezoars. We discuss the typical imaging features of bezoars causing small bowel obstruction as well as potential pitfalls that can mimic the appearance of a bezoar.

Pulse oximetry is the standard monitoring technique of functional oxygen saturation (SpO2). As the use of fingernail polish has been described to alter SpO2 readings, its removal is commonly recommended prior to measurement. Gel-based manicures have gained popularity in recent years due to their attractiveness and longevity. However, the removal of gel nail polish requires a specialised procedure. Valuable time and resources can be saved if removal can be avoided. To our knowledge, there are no available studies on the effect of gel-based manicures on pulse oximetry readings. Hence, we evaluated the effect with two oximeters, using different technology and wavelength combinations. ⋯ Gel-based manicures can result in overestimations of actual readings, delaying detection of hypoxaemia. Gel nail polish should be routinely removed or an alternative monitoring technique sought.
