1.Novel oral anticoagulants for atrial fibrillation.
Singapore medical journal 2015;56(12):657-quiz 659
Anticoagulation therapy is effective in preventing primary and secondary thromboembolic events due to atrial fibrillation. Warfarin, which was approved by the United States in 1954, was the only long-term oral anticoagulation therapy till the approval of dabigatran in 2010, and of rivaroxaban and other direct factor Xa inhibitors from 2011, forming a group known as novel oral anticoagulants (NOAC). NOAC have fewer food and drug interactions compared to warfarin; hence, the patient will require fewer clinic visits. However, the short half-life of NOAC means that twice-a-day dosing is needed and there is higher risk of a prothrombotic state when doses are missed. Other disadvantages are the lack of long-term data on NOAC, their high cost and the current lack of locally available antidotes.

4.Doctor, my dentist wants your opinion.
Singapore medical journal 2013;54(1):11-quiz p.14
Dental surgery is very common, and it is important for our dental colleagues to understand the medical history and chronic medications of our co-managed patients. Antibiotic prophylaxis is currently recommended only for patients at high risk for infective endocarditis when undergoing high-risk dental procedures. Good dental hygiene can prevent more infective endocarditis than prophylactic antibiotic therapy, as transient bacteraemia is common in daily activities such as the brushing and flossing of teeth. Most dental surgeries can generally be performed on patients taking a daily dose of aspirin, but the dentist must be able to assess the risk-benefit ratio of employing local measures of haemostasis versus stopping the antiplatelet therapy. Patients on antiplatelet with recent coronary artery stenting should be referred to their primary cardiologist regarding the cessation of these agents before any surgery.

5.PILL series. What is my ideal diabetes target?

Singapore medical journal 2012;53(12):778-quiz p. 781
Diabetes mellitus is common in our increasingly affluent and ageing population. Although it is an old friend of practising family physicians, there is a need to be familiar with and up to date about the disease. As patients become more informed and receptive to current medical information, family physicians also need to stay current. This article highlights the evidences that have shaped our current treatment targets for type 2 diabetes mellitus.

INTRODUCTIONType 2 diabetes mellitus is of increasing healthcare concern worldwide, with incidence rising, complications leading to significant morbidity and mortality, posing strain on public healthcare funding. Health-related quality of life of diabetic patients is increasingly being recognised as "the ultimate goal of all health interventions". The aim of our study was to identify the quality of life predictors of diabetic patients in primary care. This study was conducted in 8 public primary care polyclinics from SingHealth Polyclinics.
MATERIALS AND METHODSWe carried out a cross-sectional, questionnaire-based survey on 699 diabetic patients, administered by medical students on a systematic sample of patients during their routine visit. Multiple regression analysis was used to investigate the socio-demographic and clinical characteristics as predictors of quality of life, measured by the Short Form 36 Health Survey (SF-36) and the EQ-5D self-report questionnaire.
RESULTSHigher quality of life in diabetic patients is associated with younger age, male gender, employed status, higher educational level and exercise. Lower quality of life is associated with comorbidities and diabetic complications. Short-term glycaemic control as measured by HbA1c did not correlate with quality of life. Most interestingly, confidence in doctor and satisfaction in clinic were related to better quality of life.
CONCLUSIONHealth-related quality of life is adversely associated with symptomatic complications of diabetes mellitus, but not with short-term diabetic control. This suggests that the diabetic patient may not appreciate the impact of good diabetic control immediately on his or her health-related quality of life. More effort should be invested into patient education of the importance of glycaemic control to prevent these long-term complications.

7.Doctor, do I really need treatment for my current blood pressure?

Hypertension is the most common chronic condition seen in primary care. It is a potentially modifiable risk factor for cardiovascular and renal complications. The latest Joint National Committee recommendations in 2014 address common clinical questions from the best available science with regard to managing patients with hypertension. We review some of these recommendations and discuss how they may be applied in our practice.

8.Recurrent wheeze and cough in young children: is it asthma?

Singapore medical journal 2014;55(5):236-241
A clinical diagnosis of asthma is often considered when a child presents with recurrent cough, wheeze and breathlessness. However, there are many other causes of wheeze in a young child. These range from recurrent viral infections to chronic suppurative lung disease, gastro-oesophageal reflux disease and rare structural abnormalities. Arriving at a diagnosis includes taking into consideration the symptomatology, triggers, atopic features, family history, absence of red flags and therapeutic trial, where indicated.

10.When babies turn yellow.

Neonatal jaundice is a common condition seen in the primary care setting. Most afflicted babies have physiological jaundice and their prognosis is good. However, others have pathological jaundice, which must be detected early. High levels of serum bilirubin can also result in bilirubin encephalopathy. This article describes consultation tasks in the primary care setting with the aim of providing a guide for the safe management of neonatal jaundice. They include clinical assessment of the baby's well-being; looking out for features that suggest pathological jaundice; assessment for the presence of high-risk features; utilising appropriate laboratory tests for monitoring; assessing the degree of jaundice to decide if the child can be safely followed up in primary care; and providing advice on primary prevention measures and allaying parental concerns. The importance of stool colour examination and its role in early detection of cholestatic jaundice is emphasised.
