INTRODUCTIONMajor workplace related accidents pose a significant healthcare resource challenge in Singapore.

MATERIALS AND METHODSOur study looks at the epidemiology of patients who were admitted for workplace related accidents, in a single institution, with an Injury Severity Score of >9.

RESULTSThere were 196 cases of major workplace related accidents admitted between January 2006 and December 2007. The median age of patients admitted was 37 years with a large percentage being males (95.4%) and non-residents (57.1%). The most common ethnic group was Chinese (53.1%) followed by Indians (23.5%). The most common mechanism of injury was fall from height (66.3%) followed by injuries as a result of falling objects at work (21.9%). The percentage of patients who required surgical intervention was 69.9%. Patients admitted for major workplace related accidents had a median length of stay of 5 days in the hospital, a median length of 24 days of medical leave (ML), certifying them unfit for duty and the average cost of stay for each patient was S$11,000.

CONCLUSIONSWe have a better understanding of the epidemiology and socio-economic impact of workplace related accidents through this study. Workplace related accidents result in significant number of man-days lost from work and monetary cost to employers, medical insurance and the hospital. With an improved understanding, we propose methods to prevent and reduce such accidents in future. A direct consequence of which will be the possible reduction of hospitalisation costs and better allocation of healthcare resources in the future.

INTRODUCTIONSingapore is the first Asian country to establish a nationwide breast screening programme, but our breast cancer screening uptake lags behind the Western countries. This survey focused on the subject of screening mammography, to assess the reasons for non-attendance and explore ways to improve our screening uptake.

MATERIALS AND METHODSFemales ≥21 years old were approached at primary healthcare clinics to participate in this survey, which questioned their knowledge, perception and expectations of breast screening.

RESULTSThere were 1011 respondents. Of the 740 respondents ≥40 years old, 332 respondents (45.5%) went for regular mammogram screening. Women who had lower household incomes [<$2000 (OR 0.49; 95% CI, 0.28 to 0.85); $2000 to $3999 (OR 0.59; 95% CI, 0.36 to 0.97)], did not know anyone with breast cancer (OR 0.62; 95% CI, 0.42 to 0.92), did not perform breast self-examination (OR 0.42; 95% CI, 0.28 to 0.62), had lower knowledge scores (OR 0.34; 95% CI 0.22 to 0.51), did not attend other health screening (OR 0.14; 95% CI, 0.05 to 0.41), and perceived mammography as embarrassing (OR 0.55; 95% CI, 0.31 to 0.96), were less likely to attend mammographic screening. Many did not know that screening is for the asymptomatic (51.2%), or the age to start screening (46.3%). Most respondents preferred to have their mammograms in the polyclinics (62.2%) and their screening reminders to be through short messaging service (SMS) (46.0%).

CONCLUSIONOur results show the current influences on Singapore women's screening practices, and also revealed that their understanding of mammogram screening is limited despite a high level of breast cancer awareness.

Retrospective cohort study.

This study aims to analyze the relationship between body mass index (BMI) subjective patient-reported outcomes (PRO) after 1- and 2-level anterior cervical discectomy and fusion (ACDF).

The prevalence of cervical spondylosis and ACDF in expected to continue rising among the aging population of Asia. Moreover, the prevalence of obesity is also increasing. However, limited information is available about the mechanism by which BMI affects PRO after ACDF.

Total 878 patients underwent ACDF between 2000 and 2015. After excluding patients with previous cervical instrumentation, >2 levels fused, missing BMI measurement, or neoplastic/trauma indication for surgery, 535 patients were included. The PRO measures of the Neck Disability Index, Numerical Pain Rating Scale (NPRS) for Neck Pain, NPRS for Limb Pain, American Academy of Orthopaedic Surgeons–Neurogenic Symptom Score, and Japanese Orthopaedic Association myelopathy score were used. Patients were grouped based on their preoperative BMI, as per the World Health Organization guidelines for Asian populations. PRO scores were collected preoperatively, at 6 months postoperatively, and 2 years postoperatively. A generalized linear model was used to analyze the relationship of BMI category with the individual score, accounting for several factors that are likely to affect the outcomes.

Total 19 (3.4%) were underweight, 155 (28.0%) were normal weight, 112 (20.3%) were overweight, and 267 (48.3%) were obese. Patients across all BMI categories experienced significant and similar improvements in their postoperative PRO scores. There were no significant differences in the preoperative, 6-month postoperative, and 2-year postoperative PRO scores of the groups. Rate of reoperation was highest in patients with grade II obesity at 8.07%; however, the difference was not statistically significant.

Irrespective of the BMI, all patients exhibited similar satisfactory outcomes following ACDF. The results support surgery in all subgroups of patients with symptomatic nerve compression in the cervical spine.

INTRODUCTION: The COVID-19 pandemic has affected the world for more than a year, with multiple waves of infections resulting in morbidity, mortality and disruption to the economy and society. Response measures employed to control it have generally been effective but are unlikely to be sustainable over the long term. METHODS: We examined the evidence for a vaccine-driven COVID-19 exit strategy including academic papers, governmental reports and epidemiological data, and discuss the shift from the current pandemic footing to an endemic approach similar to influenza and other respiratory infectious diseases. RESULTS: A desired endemic state is characterised by a baseline prevalence of infections with a generally mild disease profile that can be sustainably managed by the healthcare system, together with the resumption of near normalcy in human activities. Such an endemic state is attainable for COVID-19 given the promising data around vaccine efficacy, although uncertainty remains around vaccine immunity escape in emergent variants of concern. Maintenance of non-pharmaceutical interventions remains crucial until high vaccination coverage is attained to avoid runaway outbreaks. It may also be worthwhile to de-escalate measures in phases, before standing down most measures for an endemic state. If a variant that substantially evades immunity emerges, it will need to be managed akin to a new disease threat, with pandemic preparedness and response plans. CONCLUSION An endemic state for COVID-19, characterised by sustainable disease control measures, is likely attainable through vaccination.

INTRODUCTIONThis study aimed to characterise interpersonal violence victims admitted to a major trauma centre.

MATERIALS AND METHODSA retrospective cohort study of interpersonal violence victims who were admitted to our centre from 1 January 2001 to 31 December 2010 was conducted. Data were obtained from our trauma registry.

RESULTSInterpersonal violence victims constituted 444 (90.1% males and 9.9% females) out of a total of 8561 trauma admissions in the same time period. The average age was 36.6 years (range, 14 to 83 years). Majority were Chinese (53.4%) and Singaporeans (77.3%). The number of cases increased from 10 per year to 96 per year in the first 8 years, then decreased in the last 2 years (55 in year 2010). Time of injury was predominantly 0000 to 0559 hours (72.3%). Interpersonal violence mostly occurred in public spaces for both genders (88.7%). However, the number of females who were injured at home was significantly higher than males (P = 0.000). Blunt trauma (58.3%) was more common than penetrating trauma (41.7%). The average injury severity score (ISS) was 13.5 (range, 1 to 75); 34.9% of patients had major trauma (ISS >15). The average Glasgow coma scale (GCS) score was 13.5 (range, 3 to 15); 16.4% of patients had moderate-to-severe brain injury (GCS 3-8). Blunt trauma was significantly more likely to cause major trauma than penetrating trauma (P = 0.003). The sole case of firearm assault caused most morbi-mortality. Overall mortality was 4.5%. Major trauma (OR: 25.856; P = 0.002) and moderate-to-severe brain injury (OR: 7.495; P = 0.000) were independent risk factors of mortality.

CONCLUSIONThere has been no prior published data on interpersonal violence locally. This study is thus useful as preliminary data for future population-based studies. It also provides data for authorities to formulate preventive and intervention strategies.

Most cases of intussusception in adults present with chronic and nonspecific symptoms, and can sometimes be challenging to diagnose. We herein report on a patient with the rare symptom of colonic intussusceptions presenting with rectal prolapse and review the existing literature of similar case reports to discuss how to reach an accurate diagnosis. A 75-year-old woman with dementia presented with per rectal bleeding, rectal prolapse and lower abdominal pain. An operation was scheduled and a large sigmoid intussusception with a polyp as a leading point was found intraoperatively. She subsequently recovered well and was discharged. As large sigmoid intussusceptions may present as rectal prolapse, intussusception should be considered as a differential diagnosis for immobile patients, especially when the leading point is a lesion.

INTRODUCTIONTraumatic diaphragmatic injuries (TDIs) are clinically challenging. We aimed to review TDIs treated at a tertiary trauma centre over a 12-year period.

METHODSThis was a single-centre retrospective review of adult patients with TDIs treated between 1 January 2003 and 31 December 2014. Primary outcomes were mortality rates and Injury Severity Scores (ISS) associated with each TDI subtype. Secondary outcomes included proportions of TDIs diagnosed radiologically, operatively or during autopsy. We compared the TDI subtypes with respect to mechanism of injury, mortality rates and median ISS. Data was analysed using descriptive statistics.

RESULTSAmong 46 patients studied, the TDI subtypes noted were acute diaphragmatic herniation (n = 14, 30.4%), tears (n = 22, 47.8%) and contusions (n = 10, 21.7%). Patients with these TDI subtypes had a mortality rate of 35.7%-100%, while the ISS ranges for survivors and deaths were 22.0-34.0 (interquartile range [IQR] 6.5-23.0) and 53.5-66.0 (IQR 16.0-28.5), respectively. TDIs were identified via chest radiography (n = 2/33, 6.1%) and computed tomography (n = 6/13, 46.2%). All survivors (n = 21) and deaths (n = 25) underwent open surgery or autopsy, respectively, which confirmed TDIs. Blunt traumas and penetrating traumas were more frequently associated with acute herniation/contusions and tears, respectively. There were statistically significant differences among the TDI subtypes in their mechanism of injury, mortality rate and median ISS of survivors.

CONCLUSIONTDIs showed varying injury patterns with blunt versus penetrating mechanisms of injury, and were associated with significant mortality rates. Preoperative imaging had limited diagnostic use.
