Abstract
Frailty, which is a geriatric syndrome that affects 5% to 17% of older adults, is a state of increased vulnerability across multiple health domains that leads to adverse health outcomes. Frail older adults are at increased risk of falls, disability, hospitalizations, and death. Frailty may initially be overlooked or incorrectly identified as part of the normal aging process because of the variable nature of the presentation and diagnosis. Symptoms include generalized weakness, exhaustion, slow gait, poor balance, decreased physical activity, cognitive impairment, and weight loss. There is no current recommendation for routine screening. A comprehensive geriatric assessment can identify risk factors and symptoms that suggest frailty. Several validated frailty assessment tools can evaluate a patient for frailty. Patients are diagnosed as not-frail, prefrail, or frail. Patients with a larger number of frail attributes are at higher risk of poor outcomes. The management of frail patients must be individualized and tailored to each patient's goals of care and life expectancy. Physical activity and balance exercises may be suitable for patients who are less frail. Palliative care and symptom control may be appropriate for those who are more frail.

Abstract
Background In 2010, Qatar adopted the target of reducing hepatitis B prevalence to < 1% in children by 2015. The World Health Organization Region for the Eastern Mediterranean is identified with intermediate hepatitis B virus (HBV) endemicity, ranging from 2% to 7%. It is estimated that 4.3 million individuals are living with HBV infection in the Region. Aims This study was conducted to assess hepatitis B seroprevalence in children, hepatitis B vaccination coverage, potential exposure to risk factors, and knowledge among parents/guardians about hepatitis B infection. Methods We carried out this cross-sectional study in Qatar during the academic year 2015/16. Multistage cluster sampling was used to select a nationally representative sample of 2735 grade 1 school students aged ≥ 5 years. Blood was collected by finger prick and tested using the point-of-care test/rapid test. A self-administered, precoded questionnaire was used to assess parent/guardian knowledge about HBV and collect information on the child's HBV vaccination coverage. Results All blood samples were HBsAg negative. Qataris had a vaccination card and were totally vaccinated but 17.7% of non-Qataris did not hold a vaccination card and most parents/guardians were not aware of the vaccination status of their children. Children were exposed to various hepatitis B risk practices. Knowledge about hepatitis B among parents/ guardians was low. Conclusions Qatar has averted the hepatitis B threat and maintained high vaccination coverage for children.

Abstract
We report the unique case of a 14-year-old male with axillary artery pseudo-aneurysm associated with brachial plexus compression after a simple shoulder dislocation. Following shoulder reduction under anaesthetic, the child was discharged on chemical deep vein thrombosis (DVT) prophylaxis. However, progressive shoulder swelling and upper limb neurological symptoms developed. A multi-disciplinary approach was taken to diagnose and treat this complication. After stopping the anti-coagulants, a combination of endovascular stent-graft and open surgical decompression of the brachial plexus was employed. Paediatric guidelines on DVT prophylaxis are scarce but DVT has never been reported in children following upper limb trauma.

Abstract
Hair loss is often distressing and can have a significant effect on the patient's quality of life. Patients may present to their family physician first with diffuse or patchy hair loss. Scarring alopecia is best evaluated by a dermatologist. Nonscarring alopecias can be readily diagnosed and treated in the family physician's office. Androgenetic alopecia can be diagnosed clinically and treated with minoxidil. Alopecia areata is diagnosed by typical patches of hair loss and is self-limited. Tinea capitis causes patches of alopecia that may be erythematous and scaly and must be treated systemically. Telogen effluvium is a nonscarring, noninflammatory alopecia of relatively sudden onset caused by physiologic or emotional stress. Once the precipitating cause is removed, the hair typically will regrow. Trichotillomania is an impulse-control disorder; treatment is aimed at controlling the underlying psychiatric condition. Trichorrhexis nodosa occurs when hairs break secondary to trauma and is often a result of hair styling or overuse of hair products. Anagen effluvium is the abnormal diffuse loss of hair during the growth phase caused by an event that impairs the mitotic activity of the hair follicle, most commonly chemotherapy. Physician support is especially important for patients in this situation.

Abstract
BACKGROUND Chlamydia trachomatis (chlamydia) is the most commonly diagnosed sexually transmitted infection (STI) in England; approximately 70% of diagnoses are in sexually active young adults aged under 25. To facilitate opportunistic chlamydia screening in general practice, a complex intervention, based on a previously successful Chlamydia Intervention Randomised Trial (CIRT), was piloted in England. The modified intervention (3Cs and HIV) aimed to encourage general practice staff to routinely offer chlamydia testing to all 15-24 year olds regardless of the type of consultation. However, when the 3Cs (chlamydia screening, signposting to contraceptive services, free condoms) and HIV was offered to a large number of general practitioner (GP) surgeries across England, chlamydia screening was not significantly increased. This qualitative evaluation addresses the following aims: a) Explore why the modified intervention did not increase screening across all general practices. b) Suggest recommendations for future intervention implementation. METHODS Phone interviews were carried out with 26 practice staff, at least 5 months after their initial educational workshop, exploring their opinions on the workshop and intervention implementation in the real world setting. Interview transcripts were thematically analysed and further examined using the fidelity of implementation model. RESULTS Participants who attended had a positive attitude towards the workshops, but attendee numbers were low. Often, the intervention content, as detailed in the educational workshops, was not adhered to: practice staff were unaware of any on-going trainer support; computer prompts were only added to the female contraception template; patients were not encouraged to complete the test immediately; complete chlamydia kits were not always readily available to the clinicians; and videos and posters were not utilised. Staff reported that financial incentives, themselves, were not a motivator; competing priorities and time were identified as major barriers. CONCLUSION Not adhering to the exact intervention model may explain the lack of significant increases in chlamydia screening. To increase fidelity of implementation outside of Randomised Controlled Trial (RCT) conditions, and consequently, improve likelihood of increased screening, future public health interventions in general practices need to have: more specific action planning within the educational workshop; computer prompts added to systems and used; all staff attending the workshop; and on-going practice staff support with feedback of progress on screening and diagnosis rates fed back to all staff.

Abstract
BACKGROUND Thyroid cancer incidence has been increasing worldwide. Some suggest greater ascertainment of indolent tumours is the only driver, but others suggest there has been a true increase. Increases in Australia appear to have been among the largest in the world, so we investigated incidence trends in the Australian state of Queensland to help understand reasons for the rise. METHODS Thyroid cancers diagnoses in Queensland 1982-2008 were ascertained from the Queensland Cancer Registry. We calculated age-standardized incidence rates (ASR) and used Poisson regression to estimate annual percentage change (APC) in thyroid cancer incidence by socio-demographic and tumour-related factors. RESULTS Thyroid cancer ASR in Queensland increased from 2·2 to 10·6/100 000 between 1982 and 2008 equating to an APC of 5·5% [95% confidence interval (CI) 4·7-6·4] in men and 6·1% (95% CI 5·5-6·6) in women. The rise was evident, and did not significantly differ, across socio-economic and remoteness-of-residence categories. The largest increase seen was in the papillary subtype in women (APC 7·9%, 95% CI 7·3-8·5). Incidence of localized and more advanced-stage cancers rose over time although the increase was greater for early-stage cancers. CONCLUSION There has been a marked increase in thyroid cancer incidence in Queensland. The increase is evident in men and women across all adult age groups, socio-economic strata and remoteness-of-residence categories as well as in localized and more advanced-stage cancers. Our results suggest 'overdiagnosis' may not entirely explain rising incidence. Contemporary aetiological data and individual-level information about diagnostic circumstances are required to further understand reasons for rising thyroid cancer incidence.

Abstract
We investigated the dynamics of accommodative and pupillary responses to random-dot stereograms presented in crossed and uncrossed disparity in six visually normal young adult subjects (mean age=25.8±3.1 years). Accommodation and pupil measures were monitored monocularly with a custom built photorefraction system while subjects fixated at the center of a random-dot stereogram. On each trial, the stereogram initially depicted a flat plane and then changed to depict a sinusoidal corrugation in depth while fixation remained constant. Increase in disparity specified depth resulted in pupil constriction during both crossed and uncrossed disparity presentations. The change in pupil size between crossed and uncrossed disparity conditions was not significantly different (p>0.05). The change in pupil size was also accompanied by a small concomitant increase in accommodation. In addition, the dynamic properties of pupil responses varied as a function of their initial (starting) diameter. The finding that accommodation and pupil responses increased with disparity regardless of the sign of retinal disparity suggests that these responses were driven by apparent depth rather than shifts in mean simulated distance of the stimulus. Presumably the need for the increased depth of focus when viewing stimuli extended in depth results in pupil constriction which also results in a concomitant change in accommodation. Starting position effects in pupil response confirm the non-linearity in the operating range of the pupil.

There has been a tremendous amount of progress toward polio eradication in the World Health Organization South-East Asia Region particularly over the past 4 years. In 1988, there were >25,000 reported cases of wild poliovirus infection in the South-East Asia Region, and because of substantial underreporting the estimated polio burden was probably 10-fold higher. Following the initiation of mass polio immunization campaigns in the mid-1990s and years of intense effort, the 11 countries of the South-East Asia Region reported no cases of wild poliovirus infection in 2012. With India reporting the last wild poliovirus case in the region, on 13 January 2011, and its subsequent removal from the list of polio-endemic countries, in February 2012, the South-East Asia Region is firmly on track for polio-free certification in early 2014.

Abstract
The Carotid Disease and Cardiac Surgery Consensus Meeting was convened as a multidisciplinary gathering to consider the management of patients undergoing cardiac surgery who are found to have asymptomatic carotid artery disease. There are no randomized trials concerning whether carotid interventions are of value in this situation and the natural history is unclear. Bilateral carotid artery disease (≥70% stenosis) should be regarded clinically relevant when considering hemodynamic and short-term surgical stroke risk. However, this may be because the presence of significant carotid disease is also a marker for aortic arch and intracerebral disease. A natural history study is urgently needed to determine the incidence, predictive factors, and natural history of asymptomatic carotid disease in patients undergoing contemporary cardiac surgical interventions to inform the design of any future randomized trial.

Abstract
BACKGROUND This paper describes the interdisciplinary management of a 62-year-old man who presented with a cervical chordoma of C2/3. This is a rare neoplasm of the axial skeleton which is usually treated surgically. This is technically challenging due to the surrounding anatomy and requirement for wide exposure. A number of surgical approaches have been described to access the clivus and upper cervical spine. METHODS This case involved both the Orthopaedic and Otolaryngology Head and Neck Surgery departments. Trotter's surgical technique was used to gain access for excision of the cervical chordoma and there was collaboration with an Orthopaedic Biotechnology Company in which a bio-model of the spine was created and a corpectomy cage specific to the patient developed. RESULTS This approach allowed excellent visualisation of the tumour and the unique cage and plate achieved immediate stability and long term fusion. CONCLUSION An interdisciplinary approach should be used in the management of upper cervical chordomas to facilitate tumour resection and reduce the potential for recurrence.
