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.

3.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.

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

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.

6.Recurrent abdominal pain in childhood.

Singapore medical journal 2013;54(4):195-quiz 200
Recurrent abdominal pain in childhood is common, and continues to be a diagnostic and therapeutic challenge. It is usually attributed to a functional gastrointestinal disorder rather than an organic disease. In most cases, a comprehensive history and physical examination should enable one to make a positive diagnosis of functional disorder. The presence of alarm symptoms and signs, such as weight loss, gastrointestinal bleeding and chronic severe diarrhoea, warrants further investigations and referral to a paediatric gastrointestinal specialist. The mainstay of therapy in functional abdominal pain is education, reassurance and avoidance of triggering factors. While symptom-based pharmacological therapy may be helpful in patients who do not respond to simple management, it is best used on a time-limited basis due to the lack of good evidence of its efficacy. The primary goal of therapy is a return to normal daily activities rather than complete elimination of pain. In recalcitrant cases, psychological interventions such as cognitive behaviour therapy and relaxation training have proven to be efficacious.

7.Menopause: an important milestone in women's health.
Singapore medical journal 2013;54(2):60-63
Menopause, a natural process in a woman's life, is defined as the cessation of menstrual period for 12 consecutive months. In Singapore, the average age of natural menopause is 49 years of age. We discuss the challenges faced by menopausal women and provide an example of a holistic approach to the management of women during this important stage of their lives.

8.PILL series. The solitary pulmonary nodule.

The solitary pulmonary nodule on chest X-ray (CXR) is a common problem in pulmonary medicine. Its presence raises the question of lung cancer. As five-year survival after resection of a solitary bronchogenic carcinoma can be as high as 80%, prompt evaluation is crucial. This should begin with a cancer risk assessment based on clinical and radiographic factors. The risk and benefits of surgery should next be assessed, and together with the patient's preferences, a management plan can be decided upon. Surgery is recommended for patients at high risk of malignancy with a low surgical risk, while careful observation is adopted for patients at low risk of malignancy coupled with a high surgical risk. Further diagnostic tests may be warranted to aid in this decision process. Although CXR is not useful for lung cancer screening, low-dose computed tomography imaging is increasingly recommended for individuals at high risk for lung cancer.

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.

10.Recurrent wheeze and cough in young children: is it asthma?
Mark Chung Wai NG ; Choon How HOW
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.
