Global public health security is both a collective aspiration and a mutual responsibility that demands cooperative action at all levels. The expansion of the current H5N1 avian influenza enzootic and its incursion into human health presents a real and significant threat of an influenza pandemic. The world has for the first time an unprecedented opportunity for pandemic preparation. Current global efforts to tackle the H5N1 pandemic threat are centred around the framework of the International Health Regulations (2005) that requires countries to openly share disease intelligence including clinical samples, viruses and epidemiological information. Present international initiatives also seek to establish more equitable allocation and sharing mechanisms for developing countries, of therapeutic resources, public health interventions and other broad-based support in the event of a pandemic. To be sustainable, country preparatory efforts need to be integrated within wider national emergency preparedness frameworks and emphasise the strengthening of basic capacities in disease surveillance, outbreak response and health systems that can respond to a range of public health emergencies. Such capacity building represents permanent investments in health that will have enduring benefits beyond a pandemic. Preparations must also go beyond the health sector; greater promotion of intersectoral cooperation and an adoption of a whole-of-society approach to preparation is recommended. Broad collaboration is vital in addressing the complex challenge posed by influenza to our collective security.

INTRODUCTIONScalp soft tissue defects are common and result from a variety of causes. Reconstructive methods should maximise cosmetic outcomes by maintaining hair-bearing tissue and aesthetic hairlines. This article outlines an algorithm based on a diverse clinical case series to optimise scalp soft tissue coverage.

MATERIALS AND METHODSA retrospective analysis of scalp soft tissue reconstruction cases performed at the Singapore General Hospital between January 2004 and December 2013 was conducted.

RESULTSForty-one patients were included in this study. The majority of defects <100 cm² were reconstructed with local flaps and were subdivided by location. Methods included rotation, transposition and free flaps. The most common type of reconstruction performed for defects ≥100 cm² was free flap reconstruction. Multistage reconstruction using tissue expanders aided in optimising cosmetic outcomes. There were no major complications or flap failures.

CONCLUSIONBy analysing our experience with scalp soft tissue reconstruction, we have developed an algorithm based on defect size and location, achieving excellent closure and aesthetic outcome while minimising complications and repeat procedures.

INTRODUCTIONThis study objectively evaluates the effectiveness of a 6-week Preparatory Training Phase (PTP) programme prior to Basic Military Training (BMT) for less physically conditioned conscripts in the Singapore Armed Forces.

MATERIALS AND METHODSWe compared exercise test results of a group of less fi t recruits who underwent a 16-week modified-BMT (mBMT) programme (consisting of a 6-week PTP and 10-week BMT phase) with their 'fitter' counterparts enlisted in the traditional 10-week direct-intake BMT (dBMT) programme in this prospective cohort study consisting of 36 subjects. The main outcome measures included cardiopulmonary responses parameters (VO(2)max and V(O2AT)) with clinical exercise testing and distance run timings.

RESULTSAlthough starting off at a lower baseline in terms of physical fitness [VO(2)max 1.73 +/- 0.27 L/min (mBMT group) vs 1.97 +/- 0.43 L/min (dBMT), P = 0.032; V(O2AT) 1.02 +/- 0.19 vs 1.14 +/- 0.32 L/min respectively, P = 0.147], the mBMT group had greater improvement in cardiopulmonary indices and physical performance profiles than the dBMT cohort as determined by cardiopulmonary exercise testing [VO(2)max 2.34 +/- 0.24 (mBMT) vs 2.36 +/- 0.36 L/min (dBMT), P = 0.085; V(O2AT) 1.22 +/- 0.17 vs 1.21 +/- 0.24 L/min respectively, P = 0.303] and 2.4 kilometres timed-run [mBMT group 816.1 sec (pre-BMT) vs 611.1 sec (post-BMT), dBMT group 703.8 sec vs 577.7 sec, respectively; overall P value 0.613] at the end of the training period. Initial mean difference in fitness between mBMT and dBMT groups on enlistment was negated upon graduation from BMT.

CONCLUSIONPre-enlistment fitness stratification with training modification in a progressive albeit longer BMT programme for less-conditioned conscripts appears efficacious when measured by resultant physical fitness.

Introduction: Schwannomas are benign biochemically non-secretory neoplasms that originate from the myelin sheaths of nerves. Functioning schwannomas, especially that of the head and neck, are exceedingly rare with only a few published in the literature. This case aims to report the uncommon presentation of a patient with a neck schwannoma in an adult female with elevated urine metanephrines Case: A 33-year-old Filipino female, non-hypertensive, was admitted for a two-year history of progressively enlarging non-tender pulsatile right lateral neck mass, without any symptoms. The patient underwent aspiration biopsy revealing no malignant cells. Contrast-enhanced CT Scan demonstrated well-defined heterogeneously enhancing soft tissue mass in the right paracervical area, with an initial impression of paraganglioma or nerve sheath tumor. To discriminate further, urine metanephrine was ordered and demonstrated high results (3.997 mg, 5.018 mg; Reference: 0-1.00 mg/24hr) on two occasions. Gadolinium-enhanced MRI showed the 6.3x3.9x4 cm mass as isointense on T1WI and hyperintense on T2WI. Despite normotension, terazosin was administered for pre-operative alpha blockade. She underwent excision of the tumor without post-operative complications. On follow-up, the histopathology and immunohistomorphologic features confirmed the mass as a Schwannoma. Four weeks later, the patient remained normotensive and repeat urine metanephrines yielded normal results (0.670 mg, 0.192 mg) Conclusion Surgery, which remains to be the cornerstone of treatment, heralded the biochemical remission of the urine metanephrines in the patient. Although there were no identified neuroendocrine elements in the histopathology, the decrease in urine metanephrines after tumor removal likely points to a secretory schwannoma

INTRODUCTIONDengue is a major public health problem in Singapore. Age-specific dengue morbidity rates are highest in the young adult population, unlike in many other Southeast Asian countries where dengue is mainly a paediatric disease. Hence, the World Health Organization (WHO) guidelines on dengue diagnosis and management which were developed using the paediatric experiences, may not be suitable for the management of adult dengue infections.

MATERIALS AND METHODSThe Early DENgue (EDEN) infection and outcome study is a collaborative longitudinal study to investigate epidemiological, clinical, viral and host-specific features of early dengue-infected adults, in an effort to identify new early markers for prognostication. Patients presenting with early undifferentiated fever were included in the study. We carried out an interim analysis to look for early indicators of severe disease.

RESULTSDuring the period of this interim study analysis, 455 febrile patients were recruited. Of these, 133 were confirmed as acute dengue cases based on dengue-specific polymerase chain reaction (PCR) results. There were significant clinical and epidemiological differences between dengue and febrile non-dengue cases. Nine per cent of the dengue cases experienced persistent tiredness, drowsiness and loss of appetite beyond 3 weeks of illness. Quantitation of viral loads using the crossover (Ct) value of real-time RT-PCR correlated with the duration of symptoms. More than half of both primary and secondary dengue cases were hospitalised. There was no dengue-related mortality in this study.

CONCLUSIONThe duration of illness and prolonged symptom duration in 9% of the subjects indicate that the burden of dengue illness is substantially different from other non-dengue febrile illness in our study cohort. Our study also highlights the paucity of early prognostic markers for dengue fever in adults.

Objective: This study aims to explore the fishing methods and occupational safety practices of fisherfolk in a coastal municipality in Central Luzon.

Methods: Key informant interviews were conducted with leaders of fishing organizations and the Municipal Agricultural Officer using a semi-structured interview guide.

Results: Fisherfolk in the selected municipality adopted a variety of fishing practices, equipment, and methods suitable for each individual or group of fisherfolk. Safety practices were either self-learned from observation of elders and family members or arose from a trial-and-error basis, with an emphasis on precautionary measures to avoid injury.

Conclusion: Fishing practices highly varies, the most prominent of which is using numerous equipment for catching fish and other marine products by hand. Occupational safety practices are mainly focused on the avoidance of hazards.
