Each of us perceives risk differently, and so do our patients. This perception of risk gets even more complex when multiple individuals and interactions are involved: the doctor, the patient-pregnant mother, the spouse-father and the foetus-unborn child. In this review, we address the relationship between different levels of information gathering, from clinical data to experiential knowledge - data, information, knowledge, perception, attitude, wisdom - and how these would impact the perception of risk and informed consent. We discuss how patients might interpret the risks of the same event differently based upon past experiences, and suggest how risk data could be presented more meaningfully for patients and family to assimilate for informed decision making. Finally, we demonstrate how patients' expectations and risk management can impact scientific research and clinical progress by way of the most topical subject of risk screening in pregnancy - non-invasive prenatal testing using cell-free DNA in maternal plasma.

INTRODUCTIONThe physiological changes that occur in menopause alter sexual function and affect well-being. Hormonal changes contribute significantly to reduced sexual function in older women and sexual dysfunction may well be amenable to treatment with exogenous hormones or other agents.
MATERIALS AND METHODSRelevant clinical studies were identified by a computerised literature search. The collated data were presented to fellow gynaecologists for review, analysis of results and discussion in a series of meetings dedicated to finding the best evidence in menopause management. The evidence was assessed and used to prepare guidelines around the management of women who are affected by sexual dysfunction in menopause.
RESULTSHormone therapy benefits many women who have dyspareunia related to vaginal atrophy, reduced libido and decreased satisfaction, particularly if these symptoms adversely affect their quality of life. Alternative agents such as tibolone and sildenafil citrate can be useful adjuncts.
CONCLUSIONSIt is increasingly important to recognise postmenopausal sexual dysfunction. Treatment of this syndrome must be individualised to the specific complaints of each woman. Hormones and other agents are relevant treatment options for properly-selected women.

INTRODUCTIONCardiovascular disease is the leading cause of death and morbidity among postmenopausal women, and oestrogen deficiency may be an important factor in its development. The role of oestrogen replacement in preventing cardiovascular disease is controversial. The aim of this descriptive review is to analyse the available data and to recommend evidence-based practice guidelines pertaining to hormone therapy in the context of cardiovascular and cerebrovascular health.
MATERIALS AND METHODSRelevant clinical trials were identified by computerised literature search. The collated data were presented to fellow gynaecologists for review, analysis of results and discussion in a series of meetings dedicated to finding the best evidence in menopause management. The evidence was used to formulate clinical practice guidelines for the management of women with significant cardiovascular risk factors.
RESULTSEvidence from animal studies and observational trials supported a cardio-protective effect of postmenopausal hormone therapy. More recent randomised clinical trial data have shown no significant reduction of coronary heart disease, and have confirmed a higher incidence of stroke and venous thromboembolism.
CONCLUSIONSThe evidence is widely divergent regarding postmenopausal hormone therapy and cardiovascular risk. More consistent data are available reporting an increased risk in the incidence of venous thromboembolism and stroke. It is important to be clear about the indications of hormone use and to utilise alternative modalities to promote cardiovascular health in the postmenopausal population.

INTRODUCTIONThe risk of malignancy index (RMI) is a scoring system used to triage benign from malignant ovarian masses. We compared the specificity and sensitivity of the four indices (RMI 1, RMI 2, RMI 3 and RMI 4) to discriminate a benign ovarian mass from a malignant one in a Southeast Asian population.
METHODSThis was a five-year retrospective study of women who were admitted for surgery due to ovarian masses. RMI scores were calculated based on standardised preoperative cancer antigen (CA)-125 levels, ultrasonography findings, menopausal status and tumour size based on ultrasonography. Postoperative histopathologic diagnosis was regarded as the definite outcome. Data were analysed using the Statistical Package for the Social Sciences, and Mann-Whitney U test was used to compare the individual RMI scores between the benign and malignant cases.
RESULTSOut of the 480 patients reviewed, 228 women aged 10-65 years were included in the study. Of these, 17 (7.5%) had malignant disease and 211 (92.5%) had benign pathology. There was no statistical difference in the RMI 1, 2, 3 and 4 scores between the benign and malignant cases. Individual variables that were analysed showed significant differences in median CA-125 level and tumour size (p = 0.044 and p < 0.0005, respectively) between the benign and malignant cases.
CONCLUSIONOur study shows that RMI is not a valuable triage tool for our Southeast Asian population. Further prospective validation, with regard to standardising results in different patient populations and centres, is required.

health concerns, triggering an escalated burden to healthsystems worldwide. The pandemic has altered people’sliving norms, yet coherently escalating countries’ socio-economic instability. This real-time consensus review aimsto describe the epidemiological trends of COVID-19pandemic across six South-East Asian nations, and country-specific experiences on pandemic preparedness, responsesand interventions.Methods: Consensus-driven approach between authorsfrom the six selected countries was applied. Countryspecific policy documents, official government mediastatements, mainstream news portals, global statisticsdatabases and latest published literature available betweenJanuary-October 2020 were utilised for information retrieval.Situational and epidemiological trend analyses wereconducted. Country-specific interventions and challengeswere described. Based on evidence appraised, a descriptiveframework was considered through a consensus. Theauthors subsequently outlined the lessons learned,challenges ahead and interventions that needs to be in placeto control the pandemic. Results: The total number of people infected with COVID-19between 1 January and 16 November 2020 had reached48,520 in Malaysia, 58,124 in Singapore, 3,875 in Thailand,470,648 in Indonesia, 409,574 in Philippines and 70,161 inMyanmar. The total number of people infected with COVID-19 in the six countries from January to 31 October 2020 were936,866 cases and the mortality rate was 2.42%. Indonesiahad 410,088 cases with a mortality rate of 3.38%, Philippineshad 380,729 cases with a mortality rate of 1.90%, Myanmarhad 52,706 cases with a mortality rate of 2.34%, Thailand had3,780 cases with a mortality rate of 1.56%, Malaysia had31,548 cases with a mortality rate of 0.79%, and Singaporehad 58,015 cases with a mortality rate of 0.05% over the 10-month period. Each country response varied depending onits real-time situations based on the number of active casesand economic situation of the country. Conclusion: The number of COVID-19 cases in thesecountries waxed and waned over the 10-month period, thenumber of cases may be coming down in one country, andvice versa in another. Each country, if acting alone, will notbe able to control this pandemic. Sharing of information andresources across nations is the key to successful control ofthe pandemic. There is a need to reflect on how thepandemic affects individuals, families and the community asa whole. There are many people who cannot afford to beisolated from their families and daily wage workers whocannot afford to miss work. Are we as a medical community,only empathising with our patients or are we doing ourutmost to uphold them during this time of crisis? Are thereany other avenues which can curb the epidemic whilereducing its impact on the health and socio-economiccondition of the individual, community and the nation?
