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.

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.

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.

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.

Vitamin D deficiency is common and may contribute to osteopenia, osteoporosis and falls risk in the elderly. Screening for vitamin D deficiency is important in high-risk patients, especially for patients who suffered minimal trauma fractures. Vitamin D deficiency should be treated according to the severity of the deficiency. In high-risk adults, follow-up serum 25-hydroxyvitamin D concentration should be measured 3-4 months after initiating maintenance therapy to confirm that the target level has been achieved. All patients should maintain a calcium intake of at least 1,000 mg for women aged ≤ 50 years and men ≤ 70 years, and 1,300 mg for women > 50 years and men > 70 years.

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.

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.
