In late 1998, a novel paramyxovirus named Nipah virus, emerged in Malaysia, causing fatal disease in domestic pigs and humans with substantial economic loss to the local pig industry. Pteropid fruitbats have since been identified as a natural reservoir host. Over the last two decades, the forest habitat of these bats in Southeast Asia has been substantially reduced by deforestation for pulpwood and industrial plantation. In 1997/1998, slash-and-burn deforestation resulted in the formation of a severe haze that blanketed much of Southeast Asia in the months directly preceding the Nipah virus disease outbreak. This was exacerbated by a drought driven by the severe 1997-1998 El Ni?o Southern Oscillation (ENSO) event. We present data suggesting that this series of events led to a reduction in the availability of flowering and fruiting forest trees for foraging by fruitbats and culminated in unprecedented encroachment of fruitbats into cultivated fruit orchards in 1997/1998. These anthropogenic events, coupled with the location of piggeries in orchards and the design of pigsties allowed transmission of a novel paramyxovirus from its reservoir host to the domestic pig and ultimately to the human population.

INTRODUCTIONBariatric surgery is increasingly recognised as an effective treatment for type 2 diabetes that significantly improves glycaemic control, even achieving remission. This study examined perceptions and concerns of diabetic patients towards bariatric surgery as a treatment option for diabetes.
MATERIALS AND METHODSA total of 150 patients were recruited from a specialised diabetic outpatient clinic and completed a questionnaire (items were rated on a Likert scale from slightly important [lowest score of 1] to extremely important [maximum score of 5]). Logistic regression was performed to identify factors influencing decision for surgery.
RESULTSThe 74 males and 76 females had mean age of 50 (range 20 to 78) and body mass index (BMI) of 29.6 kg/m(range 18.1 to 51); 61% considered surgery favourably. Predictive factors for interest in surgery: higher educational levels (OR = 2.3; 95% CI, 1.2 to 4.4), duration of diabetes (OR = 0.4; 95% CI, 0.2 to 1.0) and use of insulin (OR = 2.1; 95% CI, 1.1 to 4.1). Reasons for surgery: desire for remission (Likert scale 4.7 ± 0.7), to prevent complications (Likert scale 4.5 ± 0.9) and to reduce medications (Likert scale 4.3 ± 1.1). For those not keen on surgery, main reasons were fear of surgery (Likert scale 4 ± 1.5) and satisfaction with current therapy (Likert scale 3.7 ± 1.6).
CONCLUSIONMany diabetic patients would consider surgery as an option to improve their metabolic disorder (greater interest in patients with higher educational levels, currently using insulin and with shorter duration of diabetes). Surgical complications, length of recovery and duration of benefits were the main concerns.

INTRODUCTION:
Cigarette smoking is a leading cause of morbidity and mortality, and has a deleterious effect on dermatological conditions, such as skin cancers, hidradenitis suppurativa and psoriasis. The study aimed to evaluate the efficacy of a pharmacist-led smoking cessation clinic in reducing cigarette smoking at a tertiary referral dermatology centre. We described the impact of this clinic to provide guidance on how such a model could be further improved and implemented more widely.
METHODS:
In this single-centre, retrospective study, 74 currently smoking patients who received counselling at a structured smoking cessation clinic between January 2010 and March 2013 were identified. Information on baseline demographic characteristics and detailed past medical history, including smoking history, was collected. Follow-up was conducted at two weeks and three months.
RESULTS:
At the first follow-up at two weeks, which was attended by 57 patients, 9 (15.8%) had stopped smoking and 26 (45.6%) showed reduction in the number of cigarette sticks smoked per day, with an average reduction of 4.1 cigarette sticks per day. However, a few patients also reported no change or increased number of cigarette sticks smoked per day following counselling.
CONCLUSION
A structured pharmacist-led smoking cessation clinic is effective and can be made a part of the holistic management of dermatological conditions.
