Anzac and Empire is the remarkable story of George Foster Pearce – a carpenter who became one Australia's most influential politicians, and the man central to how Australia planned for, and fought in, World War I. The nation's longest-serving defence minister – holding the portfolio before, during and after the Great War – Pearce saw no contradiction in being both a fierce Australian nationalist, and also a loyal subject of the British Empire.Anzac and Empire is the first full-length biography of this extraordinary Australian. Written by one of Australia's leading military historians, this book shows that to understand Australia in the Great War, you must understand the man behind it.

Vitamin D in Australia : issues and recommendations

BACKGROUND A significant number of Australians and people from specific groups within the community are suffering from vitamin D deficiency. It is no longer acceptable to assume that all people in Australia receive adequate vitamin D from casual exposure to sunlight.

OBJECTIVE This article provides information on causes, consequences, treatment and prevention of vitamin D deficiency in Australia.

DISCUSSION People at high risk of vitamin D deficiency include the elderly, those with skin conditions where avoidance of sunlight is required, dark skinned people (particularly women during pregnancy or if veiled) and patients with malabsorption, eg. coeliac disease. For most people, deficiency can be prevented by 5–15 minutes exposure of face and upper limbs to sunlight 4–6 times per week. If this is not possible then a vitamin D supplement of at least 400 IU* per day is recommended. In cases of established vitamin D deficiency, supplementation with 3000-5000 IU per day for at least 1 month is required to replete body stores. Increased availability of larger dose preparations of cholecalciferol would be a useful therapy in the case of severe deficiencies. * 40 IU (international units) = 1 µg

Training general practitioners in flexible sigmoidoscopy to screen for colorectal cancer

Background: A screening programme to detect polyps or early carcinoma would significantly reduce the mortality and morbidity of colorectal cancer (CRC). The aims of the present study were to evaluate: (i) the feasibility of training general practitioners in flexible sigmoidoscopy (FS) for CRC screening; (ii) the acceptability of screening by faecal occult blood testing (FOBT) and FS in asymptomatic standard risk Australians aged over 50 years; and (iii) the yield of such screening. Methods: Subjects were recruited by general practitioner (GP) referral, newspaper advertisement or by a direct approach to retirement villages. Participants were mailed a FOBT kit and a prescreening questionnaire. Flexible sigmoidoscopy was performed by a GP supervised by an experienced endoscopist. Subjects then completed a second questionnaire. General practitioners were assessed after 50 unassisted procedures. Results: A total of 264 individuals contacted the study coordinator; 169 were screened. Screening was accepted well by the participants. Fifteen per cent of subjects had polyps and 4% had a positive FOBT. Training in FS was adversely affected by the availability of resources. Three GPs completed 50 unassisted procedures over a 15-month period, but none were able to reliably assess the distal bowel. Conclusions: Although the three trainees and their supervisors did not consider that the GPs were adequately trained after 50 unassisted procedures, training was adversely affected by limited resources within the Victorian public hospital system. Screening by FOBT and FS was considered to be acceptable by the patients undergoing these procedures. Existing facilities are not adequate if GPs are to be trained in FS as part of a national CRC screening program.

Australian consumers expectations for expanded nursing roles in general practice - choice not gatekeeping

While research has focussed on the current and potential role of the practice nurse (PN) in Australia, the acceptability of this role by consumers has not been investigated. In 2002, two independent studies were carried out into consumer perceptions of PNs. A discussion between the two groups of researchers at the inaugural National Practice Nurse Conference in 2003, identified significant similarities in the findings of these studies. This article reports the combined findings as they relate to consumers' desire for access to the health practitioner of their choice, and their concern that PNs may assume a gatekeeping role. These perceptions may have significant impact on the acceptance of PNs across Australia.

Mandatory fortification with folic acid: what would hippocrates say?

In October 2006, the Australian and New Zealand Food Regulation Ministerial Council asked for a review of the proposed food standard permitting mandatory fortification of bread with folic acid. This article contributes to the policy debate associated with the standard’s review by discussing the potential benefits and risks to the target population and the wider Australian population with emphasis on recent (2006) literature.

Association between the family environment and television viewing in Australian children

Aim: To describe the time children spend watching television (TV) and to assess associations between TV viewing time, the family environment and weight status.

Methods: Parents reported the amount of time children watched TV/video both for ‘the previous school day’ and ‘usually’ and described aspects of the family environment influencing TV access as part of a large cross-sectional study in the Barwon South-western region of Victoria, Australia. Child weight status was  based on measured height and weight. All data were collected in 2003/2004.

Results: A total of 1926 children aged 4–12 years participated. Parent-reported mean ± SE TV time for the previous school day was 83 ± 1.5 min. Children who lived in a family with tight rules governing TV viewing time (22%), or who never watched TV during dinner (33%), or had only one TV in the household (23%) or had no TV in their bedroom (81%) had significantly less TV time than their  counterparts. Overweight or obese children had more TV time than healthy weight children 88 ± 2.9 versus 82 ± 1.7 min per day (P = 0.04). They were also more likely to live in a household where children had a TV in their bedroom than healthy weight children (25% vs. 17%, P < 0.001).

Conclusion: Strategies to reduce TV time should be included as part of broader strategies to prevent childhood obesity. They should include messages to parents about not having a TV in children’s bedrooms, encouraging family rules restricting TV viewing, and not having the TV on during dinner.

Corticosteroid induced osteoporosis : guidelines for treatment

BACKGROUND: Last year, Australian Family Physician published Guidelines for Management of Postmenopausal Osteoporosis'. which were developed by Osteoporosis Australia. Recently, significant advances in our understanding of the treatment of corticosteroid osteoporosis have occurred.

OBJECTIVE: The following guidelines also developed by Osteoporosis Australia, and supported by the National Asthma Campaign, are to help general practitioners identify those patients at risk of this problem and to provide information about current treatment strategies.

DISCUSSION: Corticosteroids are widely used and effective agents for the control of many inflammatory diseases. Corticosteroid osteoporosis is a common problem associated with the long term high dose use of these medications.

Men and osteoporosis

BACKGROUND: While strict criteria have been developed for defining osteoporosis in women (bone mineral density measurements more than 2.5 standard deviations below the mean for young adult normal women, i.e. t-score value < -2.5), there still remains a controversy regarding the definition in men. Spinal fractures occur in 5% and hip fractures in 6% of men older than 50 years. There are significant differences between men and women with respect to the pathogenesis of osteoporosis, underlying medical conditions and postfracture sequelae.

OBJECTIVE: To provide an overview of the pathogenesis, diagnosis and prevention of osteoporosis in men.

DISCUSSION: Osteoporosis is increasingly recognised. Data from the Dubbo Osteoporosis Epidemiology Study suggests that 30% of men in Australia aged over 60 years will suffer from an osteoporotic fracture. It is estimated that 30-60% of men presenting with spinal fractures will have another illness contributing to their bone loss. Osteoporotic fractures in men are associated with higher morbidity and mortality than in women. Lifestyle changes together with daily calcium supplementation should be implemented and vitamin D3 should be considered in men with osteopenia.

Knowledge, attitudes and experience associated with testing for prostate cancer: a comparison between male doctors and men in the community

Background: Debate about testing for prostate cancer using prostate-specific antigen (PSA) and digital rectal examination (DRE) continues. The evidence of benefit from screening for prostate cancer using PSA tests is inconclusive, and it is unclear how PSA can be used most effectively in the detection of prostate cancer. Given the lack of consensus, it is important that consumers understand the issues in a way that will permit them to decide whether or not to have a test and, if symptomatic, how their condition is managed.

Aims: To compare prostate cancer knowledge, attitudes and testing experiences reported by male doctors and men in the community, despite the lack of evidence of a benefit.

Methods : The primary method for ascertaining the attitudes of male doctors (MD) was a telephone survey, with some doctors electing to complete a written survey. Each MD was selected, at random, from a register of male practitioners aged ≥ 49 years of age. A total of 266 MD participated in the survey. The community sample (CS) was accessed using a telephone survey. Five hundred male Victorian residents aged ≥ 49 years of age participated in the study.

Results:
Knowledge − Overall, 55% of the CS indicated ­correctly that prostate disease is sometimes cancer, compared to 83% of MD.

Attitudes − Fifty-five per cent of MD believed men should be tested for prostate disease at least every 2 years, compared to 68% of men in the CS.

Testing experience − Forty-five per cent of MD had been tested for prostate cancer in the past, and 92% of those tests were reported as negative. In the CS, 56% had been tested for prostate cancer in the past, and 78% of the results were reported as negative. The ­significant independent predictors of having had a prostate test among MD were: (i) age (≥ 60 years; odds ratio (OR): 1.59; 95% confidence intervals (CI): 1.30−1.88) and (ii) positive attitudes towards regular testing for prostate cancer (OR: 2.27; 95% CI: 1.98−2.56). The significant independent predictors for the CS were: (i) age (≥ 60 years; OR: 1.65; 95% CI: 1.40−1.89), (ii) being married (OR: 1.30; 95% CI: 1.00−1.60), (iii) knowledge that prostate disease was sometimes cancer (OR: 1.46; 95% CI: 1.26−1.66) and (iv) positive attitudes towards regular testing for prostate cancer (OR: 2.12; 95% CI: 1.90−2.34).

Conclusions: The results highlight that testing for prostate cancer is widespread in the community and in the medical profession. Further research should be undertaken to identify how to help men make fully informed decisions about prostate cancer testing.

Painful nipples in nursing mothers: fungal or staphylococcal?

Painful nipples, or ‘breast thrush’, in nursing mothers is a well recognised condition. It is a clinical diagnosis characterised by intense nipple pain often radiating into the breast, especially during breastfeeding. Between feeds it may cause a burning sensation and tenderness; breastfeeding may be abandoned because of it.

Cognitive behavioural strategies for general practice

Cognitive behavioural strategies (CBS) are circumscribed psychologial skills that can be incorporated into general practice, and need to be distinguished from cognitive behavioural therapy (CBT), a comprehensive therapeutic approach which require more intensive training.  The CBS outlined in this article can be integrated with other behavioural and structured problem solving approaches.

Australian gp's preferences for education about depression and related disorders

OBJECTIVE: To Investigate Australian general practitioners' experiences of accessing education about depression and their preferences for future education on depression and related disorders.
METHOD: Six hundred and eight anonymous surveys were distributed to GPs through 52 rural and urban divisions of general practice; 420 were retumed.
RESULTS: Educational formats involving direct contact with people having mental health expertise were highly valued. Distance education and web based technologies were least used. In the previous year, women and older GPs had spent more time on education about depression. Most intended to undertake more such education in the future and said that education in psychosocial strategies would be very useful. General practitioners' attitudes to further education about depression were influenced by their gender, practice location, and their previous mental health training.
DISCUSSION: More face-to-face training may be desirable to take advantage of GPs' willingness to spend more time on education about depression and related disorders.

Guidelines for the management of postmenopausal osteoporosis for GPs

BACKGROUND : Since the last series of guidelines on the management of osteoporosis from Osteoporosis Australia was published in Australian Family Physician (October 2002), there have been further advances in our understanding of the treatment involved in both the prevention of bone loss and the management of established osteoporosis.

OBJECTIVE : This article provides updated guidelines for the management of postmenopausal osteoporosis to assist general practitioners identify those women at risk, and reviews current treatment strategies.

DISCUSSION : Osteoporosis and its associated problems are major health concerns in Australia, especially with an aging population. While important principles of management are still considered to be maximising peak bone mass and preventing postmenopausal bone loss, new clinical trial data about drugs such as the bisphosphonatesr raloxifene and oestrogen have recently become available and the relative role of various agents is gradually becoming clearer. The use of long term hormone therapy has mixed risks and benefits that requires individual patient counselling.

Can Australain general practitioners tackle chidhood overweight/obesity? Methods and processes from the LEAP (live, eat, and play) randomized controlled trial

Background: General practitioners (GPs) could make an important contribution to management of childhood overweight. However, there are no efficacy data to support this, and the feasibility of this approach is unknown.

Objectives: To determine if GPs and families can be recruited to a randomized controlled trial (RCT), and if GPs can successfully deliver an intervention to families with overweight/obese 5- to 9-year-old children.

Methods: A convenience sample of 34 GPs from 29 family medical practices attended training sessions on management of childhood overweight. Practice staff trained in child anthropometry conducted a cross-sectional body mass index (BMI) survey of 5- to 9-year-old children attending these practices. The intervention focused on achievable goals in nutrition, physical activity and sedentary behaviour, and was delivered in four solution-focused behaviour change consultations over 12 weeks.

Results: General practitioners were recruited from across the sociodemographic spectrum. All attended at least two of the three education sessions and were retained throughout the trial. Practice staff weighed and measured 2112 children in the BMI survey, of whom 28% were overweight/obese (17.5% overweight, 10.5% obese), with children drawn from all sociodemographic quintiles. Of the eligible overweight/obese children, 163 (40%) were recruited and retained in the LEAP RCT; 96% of intervention families attended at least their first consultation.

Conclusions: Many families are willing to tackle childhood overweight with their GP. In addition, GPs and families can participate successfully in the careful trials that are needed to determine whether an individualized, family-based primary care approach is beneficial, harmful or ineffective.

Climate change and human health: what can GPs do?

In recent months articles in the most respected peer reviewed medical journals in Australia, the USA and Britain have called for urgent action to reduce climate change.1–4 The chief scientist of the United Kingdom has described climate change as ‘the most severe problem that we are facing today – more serious even than the threat of terrorism’.5 Yet, many of you will wonder if this is really such an urgent issue, and – even if it is – what on earth has it got to do with general practice?
