Abstract
Africa's HIV/AIDS situation remains cause for concern. The impact of HIV is considerable and threatens the survival and development of African societies. Although much has been attempted, the results still leave much to be desired. AIDS is an epidemic that needs to be addressed with much creativity and spirit of initiative. It is against this background that the 3rd African conference on the social aspects of HIV/AIDS brought innovations in the way international conferences are designed, activities implemented and results obtained. The innovations concerned the approach to international conferences and take into account reconceptualising HIV/AIDS so as to encourage holistic approaches and better visibility of vulnerable groups. The activities of the conference were organised in such a way as to get people living with HIV/AIDS (PLWHA), grassroots communities and marginalised groups to play a focal role. The conference offered an opportunity for developing cultural activities that would translate the African cultural concepts that had been identified as important in the HIV situation and response analysis. Interaction at the conference created an opportunity to analyse the various dimensions of the political, cultural and economic determinants. The conference offered food for thought around response construction while singling out the themes of urgency and acceleration of response, synergy construction, and coordination and conception of political responses.

Abstract
BACKGROUND This article is part of a project to determine the cost-effectiveness of averting the burden of disease. We used population data to investigate the costs and benefits of allocating resources to optimal treatment for asthma in adults, using a burden of disease framework. METHODS We calculated the population burden of asthma in the absence of any treatment as years lived with disability (YLD), ignoring the years of life lost. We then estimated the proportion of burden averted with current interventions, the proportion that could be averted with optimally implemented current evidence-based guidelines and the direct treatment cost-effectiveness ratio in dollarA per YLD averted for both current and optimal treatment. RESULTS The direct treatment cost of current treatment of adult asthma in Australia was dollar A452 million and averted 25% of the burden with a cost-effectiveness ratio of dollar A14 000/YLD averted. Optimal treatment and optimal compliance would cost dollar A627 million and avert 69% of the burden with a cost-effectiveness ratio of dollar A7000/YLD averted. CONCLUSION Implementation of optimal treatment for asthma is affordable, will be more cost-effective and will significantly decrease disability.

Abstract
The devolution of care into nontraditional community-based settings has led to a proliferation of sites for health and social care. Despite recent (re)formulations of 'evidence-based' approaches that stress the importance of optimizing interventions to best practice by taking into account the uniqueness of place, there is relatively little guidance in the literature and few attempts to systematically 'unpack' key dimensions of settings most relevant to policy, practice and research. In this paper, we explore how place matters for health and social care. In effect, we propose making place the lens through which to view practice, and not simply an interesting sideline focus. We focus specifically on (a) the emplacement of power relations in health and social care in and across settings; and (b) the pervasive (and often unrecognised) influence of technology on and in place (both 'mundane' and more visible 'high' technologies) as arguably among the most significant and pervasive (and often overlooked) dimensions of place pertinent to health and social care in both traditional (institutional) and nontraditional (community) settings. Drawing on diverse disciplinary literatures, we seek to make visible certain issues and bodies of work that health professionals may not be aware of, and which often remain inaccessible to practitioners and applied researchers on account of their density, complexity, and specialised terminology. In particular, drawing on the rich tradition of cultural studies, we advance the culture of place as a rubric for understanding the complex interrelationship between power, technology, culture, and place. Several fruitful avenues for place-sensitive research of health and social care practice (and its effects) are suggested.

Abstract
BACKGROUND There have been few large-scale epidemiological studies which have examined the prevalence of bipolar disorder. The authors report 12-month prevalence data for DSM-IV bipolar disorder from the Australian National Survey of Mental Health and Well-Being. METHOD The broad methodology of the Australian National Survey has been described previously. Ten thousand, six hundred and forty-one people participated. The 12-month prevalence of euphoric bipolar disorder (I and II)--similar to the euphoric-grandiose syndrome of Kessler and co-workers--was determined. Those so identified were compared with subjects with major depressive disorder and the rest of the sample, on rates of co-morbidity with anxiety and substance use disorders as well as demographic features and measures of disability and service utilization. Polychotomous logistic regression was used to study the relationship between the three samples and these dependent variables. RESULTS There was a 12-month prevalence of 0-5 % for bipolar disorder. Compared with subjects with major depressive disorder, those with bipolar disorder were distinguished by a more equal gender ratio; a greater likelihood of being widowed, separated or divorced; higher rates of drug abuse or dependence; greater disability as measured by days out of role; increased rates of treatment with medicines; and higher lifetime rates of suicide attempts. CONCLUSIONS This large national survey highlights the marked functional impairment caused by bipolar disorder, even when compared with major depressive disorder.

Abstract
OBJECTIVE Treatment attrition represents a considerable problem for efficient delivery of care for mental disorders. The present study examined rates and predictors of pretreatment attrition and dropout from outpatient treatment for anxiety disorders. METHOD The influence of clinical, demographic, clinician and system variables on pretreatment attrition (treatment refusal or non-attendance) and dropout were analysed in a consecutive sample of 731 clients treated at an anxiety disorders clinic in Sydney. RESULTS Pretreatment attrition was common (30.4%) but dropout once clients had commenced treatment was rare (10.3%). Milder pretreatment symptoms were associated with treatment dropout and comorbid depression or depressive symptoms were associated with higher probability of both pretreatment attrition and dropout. Demographic, clinician and system influences were present but less important. CONCLUSION Targeting of individuals with comorbid anxiety and depression may reduce treatment attrition rates among individuals with anxiety disorders presenting for treatment.

Abstract
Lesions of the glenoid labrum and ligamentous structures commonly occur secondary to shoulder trauma and are a frequent cause of shoulder joint instability. Numerous eponyms, acronyms and subclassifications are used to describe the often confusing array of bony and labro-ligamentous abnormalities of the shoulder. This aim of this review is to illustrate the relevant features of these lesions and to provide a systematic and practical approach to imaging of the shoulder using MR arthrography.

Abstract
BACKGROUND The present paper describes a component of a large population cost-effectiveness study that aimed to identify the averted burden and economic efficiency of current and optimal treatment for the major mental disorders. This paper reports on the findings for the anxiety disorders (panic disorder/agoraphobia, social phobia, generalized anxiety disorder, post-traumatic stress disorder and obsessive compulsive disorder). METHOD Outcome was calculated as averted 'years lived with disability' (YLD), a population summary measure of disability burden. Costs were the direct health care costs in 1997-8 Australian dollars. The cost per YLD averted (efficiency) was calculated for those already in contact with the health system for a mental health problem (current care) and for a hypothetical optimal care package of evidence-based treatment for this same group. Data sources included the Australian National Survey of Mental Health and Well-being and published treatment effects and unit costs. RESULTS Current coverage was around 40% for most disorders with the exception of social phobia at 21%. Receipt of interventions consistent with evidence-based care ranged from 32% of those in contact with services for social phobia to 64% for post-traumatic stress disorder. The cost of this care was estimated at dollar 400 million, resulting in a cost per YLD averted ranging from dollar 7761 for generalized anxiety disorder to dollar 34 389 for panic/agoraphobia. Under optimal care, costs remained similar but health gains were increased substantially, reducing the cost per YLD to < dollar 20 000 for all disorders. CONCLUSIONS Evidence-based care for anxiety disorders would produce greater population health gain at a similar cost to that of current care, resulting in a substantial increase in the cost-effectiveness of treatment.

Abstract
BACKGROUND Previous research has yielded conflicting evidence regarding the long-term cognitive outcome of depression. Some studies have found evidence for a higher incidence of subsequent cognitive impairment or dementia, while others have refuted this. METHOD Depression, neuropsychological performance, functional ability and clinical variables were assessed in a sample of patients who had been hospitalized for depression 25 years previously. RESULTS Data were available on 71 depressed patients (10 of whom were deceased) and 50 surgical controls. No significant differences were found between depressed subjects and controls on any neuropsychological measure. Ten depressed patients but no controls were found to have dementia at follow-up (continuity corrected chi2 = 5.93, P < 0.01). Presence of dementia was predicted by older age at baseline. Vascular dementia was the most common type. CONCLUSIONS We conclude that this study did not find evidence that early onset depression is a risk factor for Alzheimer's disease, but that for a small subgroup there appears to be a link with vascular dementia. Several plausible explanations for this link, such as lifestyle factors, require further investigation.

Abstract
BACKGROUND This article reports data on social phobia from the first large scale Australian epidemiological study. Prevalence rates, demographic correlates and co-morbidity in the sample that met criteria for social phobia are reported and gender differences examined. METHOD Data were obtained from a stratified sample of 10641 participants as part of the Australian National Survey of Mental Health and Well-Being (NSMHWB). A modified version of the Composite International Diagnostic Interview (CIDI) was used to determine the presence of social phobia, as well as other DSM-IV anxiety, affective and substance use disorders. The interview also screened for the presence of nine ICD-10 personality disorders, including anxious personality disorder, the equivalent of DSM-IV avoidant personality disorder (APD). RESULTS The estimated 12 month prevalence of social phobia was 2.3%, lower than rates reported in several recent nationally representative epidemiological surveys and closer to those reported in the Epidemiological Catchment Area study (ECA) and other DSM-III studies. Considerable co-morbidity was identified. Data indicated that the co-morbidity with depression and alcohol abuse and dependence were generally subsequent to onset of social phobia and that the additional diagnosis of APD was associated with a greater burden of affective disorder. Social phobia most often preceded major depression, alcohol abuse and generalized anxiety disorder. CONCLUSIONS Social phobia is a highly prevalent, highly co-morbid disorder in the Australian community. Individuals with social phobia who also screen positively for APD appear to be at greater risk of co-morbidity with all surveyed disorders except alcohol abuse or dependence.

Abstract
Anxiety disorders are prevalent and disabling and despite the fact that effective interventions are available, many people do not access effective treatment. Clinician decisions are fundamental determinants of access to this treatment. Despite this, treatment decisions have never been examined specifically in this group and are rarely examined in outpatient settings. The present study assessed 550 consecutive referrals to an anxiety disorders clinic in Sydney, Australia. Logistic regression was used to examine the predictors of decisions about treatment. Clinical patient variables (diagnosis and disability) were the strongest predictors of an offer of treatment but demographics and resource availability were also significant. Some of the same factors have been shown to influence the decision to seek treatment for anxiety. Both help-seeking behavior and treatment decision making are important determinants of access to care and both should be examined in future studies.

Abstract
BACKGROUND Two new screening scales for psychological distress, the K6 and K10, have been developed but their relative efficiency has not been evaluated in comparison with existing scales. METHOD The Australian National Survey of Mental Health and Well-Being, a nationally representative household survey, administered the WHO Composite International Diagnostic Interview (CIDI) to assess 30-day DSM-IV disorders. The K6 and K10 were also administered along with the General Health Questionnaire (GHQ-12), the current de facto standard of mental health screening. Performance of the three screening scales in detecting CIDI/DSM-IV mood and anxiety disorders was assessed by calculating the areas under receiver operating characteristic curves (AUCs). Stratum-Specific Likelihood Ratios (SSLRs) were computed to help produce individual-level predicted probabilities of being a case from screening scale scores in other samples. RESULTS The K10 was marginally better than the K6 in screening for CIDI/DSM-IV mood and anxiety disorders (K10 AUC: 0.90, 95%CI: 0.89-0.91 versus K6 AUC: 0.89, 95%CI: 0.88-0.90), while both were significantly better than the GHQ-12 (AUC: 0.80, 95%CI: 0.78-0.82). The SSLRs of the K10 and K6 were more informative in ruling in or out the target disorders than those of the GHQ-12 at both ends of the population spectrum. The K6 was more robust than the K10 to subsample variation. CONCLUSIONS While the K10 might outperform the K6 in screening for severe disorders, the K6 is preferred in screening for any DSM-IV mood or anxiety disorder because of its brevity and consistency across subsamples. Precision of individual-level prediction is greatly improved by using polychotomous rather than dichotomous classification.

Abstract
BACKGROUND A 10-question screening scale of psychological distress and a six-question short-form scale embedded within the 10-question scale were developed for the redesigned US National Health Interview Survey (NHIS). METHODS Initial pilot questions were administered in a US national mail survey (N = 1401). A reduced set of questions was subsequently administered in a US national telephone survey (N = 1574). The 10-question and six-question scales, which we refer to as the K10 and K6, were constructed from the reduced set of questions based on Item Response Theory models. The scales were subsequently validated in a two-stage clinical reappraisal survey (N = 1000 telephone screening interviews in the first stage followed by N = 153 face-to-face clinical interviews in the second stage that oversampled first-stage respondents who screened positive for emotional problems) in a local convenience sample. The second-stage sample was administered the screening scales along with the Structured Clinical Interview for DSM-IV (SCID). The K6 was subsequently included in the 1997 (N = 36116) and 1998 (N = 32440) US National Health Interview Survey, while the K10 was included in the 1997 (N = 10641) Australian National Survey of Mental Health and Well-Being. RESULTS Both the K10 and K6 have good precision in the 90th-99th percentile range of the population distribution (standard errors of standardized scores in the range 0.20-0.25) as well as consistent psychometric properties across major sociodemographic subsamples. The scales strongly discriminate between community cases and non-cases of DSM-IV/SCID disorders, with areas under the Receiver Operating Characteristic (ROC) curve of 0.87-0.88 for disorders having Global Assessment of Functioning (GAF) scores of 0-70 and 0.95-0.96 for disorders having GAF scores of 0-50. CONCLUSIONS The brevity, strong psychometric properties, and ability to discriminate DSM-IV cases from non-cases make the K10 and K6 attractive for use in general-purpose health surveys. The scales are already being used in annual government health surveys in the US and Canada as well as in the WHO World Mental Health Surveys. Routine inclusion of either the K10 or K6 in clinical studies would create an important, and heretofore missing, crosswalk between community and clinical epidemiology.

Abstract
The Australian Longitudinal Study of Ageing (ALSA) aims to identify factors that contribute to & predict the health & social well-being of older Australians. Analyses were performed to determine the predictive value of anthropometric measurements in older Australians for four-year mortality. Weight, height, skinfolds (triceps, abdominal, supra-spinale, sub-scapular, medial calf, and front thigh) & girth (arm, waist, hip, calf) measurements were performed on a randomly selected community-living sample of 772 men & 624 women aged>70 years. Waist: Hip, % weight loss, corrected-arm-muscle area (CAMA) & BMI were calculated. These measures were categorised into quartiles & also according to commonly adopted definitions of nutritional status. Cox regression analysis was undertaken to assess the predictive value of the independent anthropometric variables for four-year mortality, adjusting for potential confounders (age, gender, marital status, smoking, alcohol status, self-rated health, basic activities of daily living & co-morbidity). Risk of four-year mortality increased with weight loss >10% over two years (HR=2.53, CI=1.37-4.67) & CAMA <21.4cm2(M) & <21.6cm2(F) (HR=1.93, CI=1.03-3.60) independent of confounding variables. These results confirm that selected anthropometric indices (weight loss, CAMA) independently increase the risk of four-year mortality & highlights their potential use in the nutrition screening and assessment of community-living older adults.

Abstract
BACKGROUND This paper reports population data on DSM-IV generalized anxiety disorder from the Australian National Survey of Mental Health and Well-Being. METHODS The data were obtained from a nationwide household survey of adults using a stratified multi-stage sampling process. A response rate of 78.1% resulted in 10,641 persons being interviewed. Diagnoses were made using the Composite International Diagnostic Interview. The interview was computerized and conducted by trained lay interviewers. RESULTS Prevalence in the total sample was 2.8% for 1-month GAD and 36% for 12-month GAD. Persons over 55 years of age were less likely to have GAD than those in the younger age groups. Logistic regression analysis also showed that a diagnosis of GAD was significantly associated with being of younger to middle age, being separated divorced or widowed, not having tertiary qualifications or being unemployed. Co-morbidity with another affective, anxiety, substance use or personality disorders was common, affecting 68% of the sample with 1-month DSM-IV GAD. GAD was associated with significant disablement, and 57% of the sample with DSM-IV GAD had consulted a health professional for a mental health problem in the prior 12 months. CONCLUSIONS The survey provides population data on DSM-IV GAD and its correlates. GAD is a common disorder that is accompanied by significant morbidity and high rates of co-morbidity with affective and anxiety disorders, and is associated with marital status, education, employment status, but not sex. Changes to DSM-IV diagnostic criteria did not appear to affect the prevalence rate compared to previous population surveys.

Abstract
BACKGROUND In evidence-based medicine, stratum-specific likelihood ratios (SSLRs) are now being increasingly recognized as a more convenient and generalizable method to interpret diagnostic information than an optimal cut-off and its associated sensitivity and specificity. We previously examined the SSLRs of the General Health Questionnaire (GHQ) in primary care settings. The present paper aims to examine if these SSLRs are generalizable to the community settings. METHODS The Composite International Diagnostic Interview (CIDI) and the GHQ were administered on a representative sample of the Australian population in the Australian National Survey of Mental Health and Well-Being. We first compared the SSLRs of GHQ in urban Australia with the estimates that we had previously obtained from the developed urban centres in the WHO Psychological Problems in General Health Care study. If the SSLRs in the community were found to differ significantly from those in the primary care, we sought for explanatory variables. RESULTS The SSLRs in urban Australia and in the urban centres in the WHO study were significantly different for three out of the six strata. When we limited the sample to those with physical problems who visited a health professional, however, the SSLRs in the Australian study were strikingly close to those observed for primary care settings. CONCLUSIONS Different sets of SSLRs apply to primary care and general population samples. For general population surveys in developed countries, the results of the Australian National Survey represent the currently available best estimates. For developing countries or rural areas, the results are less definitive and an investigator may wish to conduct a pilot study.

Abstract
BACKGROUND AND AIMS Falls are major contributors to disability, morbidity and death for older people. Frequently, falls-related data for each of these areas is viewed in isolation. The aim of this study was to establish trends in incidence of falls-related events including: community reporting of falls and falls-related injuries, hospitalizations as a result of accidental falls, and mortality related to accidental falls for older people in two states of Australia (Victoria and South Australia). METHODS We analysed data sets for falls hospitalizations and mortality rates for the period 1988 to 1997, and from two longitudinal population-based proportional samples during the same time period. RESULTS Age-standardised falls mortality rates have steadily declined in Victoria, and remained unchanged between 1988 and 1997 in South Australia. In both states, age-standardised falls hospitalization rates have increased significantly (in Victoria, RR=1.32, 95% CI: 1.30-1.34; and South Australia, RR=1.05, 95% CI: 1.03-1.06). In both states, there was a clear age-related effect, with those in the 85-year and older age group having a falls-related mortality rate approximately 40 times that of those aged 65-69 years, and a hospitalization rate 9 times that of those in the 65-69 age group. The community studies indicated that falls rates remain high among older Australians, and that injurious falls occurred in 10% in the first wave of data collection in each of these studies. CONCLUSIONS The results highlight that various indicators related to falls trends taken in isolation may yield differing conclusions. For a true reflection of the effectiveness of falls prevention programs, falls-related mortality, hospitalization and community data need to be integrated. Increased focus on falls prevention activity in Australia during the 1990's has not reduced the magnitude of this major public health problem.

Abstract
Intraperitoneal (i.p.) bleeding causes intense inflammatory reactions and extensive adhesions. The relationship between i.p. bleeding and adhesions is well documented in both animal and human studies. Over an 8-year period, we performed 362 permanent peritoneal dialysis (PD) catheter placements in 317 patients, using the laparoscopic technique. In the first 203 procedures (group I), we observed intra-operative bleeding in 12 patients (intra-operative i.p. bleeding seen laparoscopically, and significant blood-tinged dialysate irrigation). Patients were left dry for 3-5 days before dialysate instillation during the break-in period. During the break-in period, 7 of the 12 patients (58%) developed primary catheter failure requiring catheter removal (p = 0.03). All 7 patients underwent repeat laparoscopy for placement of a new catheter. In all 7 patients, laparoscopy showed significant adhesions. In the subsequent 159 procedures (group II), we observed intra-operative bleeding in 10 patients. We irrigated the peritoneal cavity repeatedly, until clear dialysate was obtained, then instilled 500-1000 mL 1.5% Dianeal solution (Baxter Healthcare Corporation, Deerfield, IL, U.S.A.) and capped the catheter. These patients were then placed on low-volume continuous cycling peritoneal dialysis [(CCPD) 700-1200 mL, based on the patient's size, every 2 hours, until the effluent became clear]. Following this, patients underwent daily irrigation and PD fluid cell count, and were left with 700-1200 mL dialysate to dwell. The process was continued until PD fluid drainage showed no red blood cells or until the patient was started on routine peritoneal dialysis. None of these patients were drained dry. Compared with group I, no patient among the 10 in group II developed catheter failure (p = 0.001), and mean catheter survival was 31 +/- 7 months. Of the 10 patients, 2 developed exist-site leaks, both after clearance of red blood cells from the drained dialysate. None developed peritonitis. We conclude that intra-operative i.p. bleeding associated with significant blood-tinged dialysate irrigation may lead to local adhesions if the peritoneum is drained dry. The result may be loss of the PD catheter in about 60% of cases. Continuous irrigation, combined with a moderate amount of Dianeal solution left to dwell, or early initiation of low-volume PD, or both, prevents this complication.

Abstract
Studies in the uremic rat indicate that insulin resistance and glucose intolerance leading to dyslipidemia are associated with a hyperparathyroid-induced increase in cytosolic calcium ([Ca++i]). These alterations are reversed with verapamil, but recur after discontinuation of the drug, suggesting that increased [Ca++i] is responsible for the metabolic derangement. To our knowledge, no similar studies have been conducted in humans. We retrospectively examined, over 12-year period, the effects of factors that lower [Ca++i] on total serum cholesterol and triglycerides in 176 peritoneal dialysis (PD) patients. Because the study was retrospective, detailed lipid profiles were not available. We therefore relied on the morbidity and mortality outcome related to atherosclerotic vascular disease. Diabetic patients were excluded from the study, because their dyslipidemia and vascular disease are mediated via a different mechanism. The patients were classified into four groups. Group I [high parathyroid hormone (PTH) in the absence of calcium channel blockers (CCBs), n = 56] represented the highest [Ca++i]. Group II (high PTH in the presence of CCBs, n = 43) and group III (lower PTH in the absence of CCBs, n = 37) represented intermediate [Ca++i]. Group IV (lower PTH in the presence of CCBs, n = 40) represented the lowest [Ca++i]. High PTH was defined as > or = 3.0 times normal; lower PTH, as < 3.0 times normal. Lower [Ca++i] was achieved through the use of CCBs, or through lower PTH, or both. Lower PTH was achieved by parathyroidectomy or calcitriol administration. The four groups showed no differences in age, sex, race, weight, dialysis duration, or primary disease. Group I showed a mean serum cholesterol of 358 +/- 27 mg/dL and serum triglycerides of 469 +/- 41 mg/dL. Group II showed mean serum cholesterol of 198 +/- 21 mg/dL and serum triglycerides of 147 +/- 17 mg/dL. Group III showed a mean serum cholesterol of 205 +/- 20 mg/dL and serum triglycerides of 174 +/- 16 mg/dL. Group IV showed mean serum cholesterol of 184 +/- 10 mg/dL (p = 0.008) and serum triglycerides of 103 +/- 8 mg/dL (p = 0.005). The cardiovascular morbidity and mortality incidences were: group I, 64%; group II, 27%; group III, 31%; and group IV, 20% (p = 0.002). We conclude that, in non diabetic PD patients, dyslipidemia is related to a hyperparathyroid-induced increase in cytosolic calcium [Ca++i]. Lowering [Ca++i] by decreasing the parathormone level (via parathyroidectomy or calcitriol administration), or by blocking calcium entry into cells (via CCBs), or both, is associated with less dyslipidemia and improved long-term morbidity and mortality related to atherosclerotic vascular disease.

Abstract
OBJECTIVE To provide normative data on the Kessler Psychological Distress Scale (K10), a scale that is being increasingly used for clinical and epidemiological purposes. METHOD The National Survey of Mental Health And Well-Being was used to provide normative comparative data on symptoms, disability, service utilisation and diagnosis for the range of possible K10 scores. RESULTS The K10 is related in predictable ways to these other measures. IMPLICATIONS The K10 is suitable to assess morbidity in the population, and may be appropriate for use in clinical practice.

Abstract
We compared serum concentrations of zinc, chromium, and iron in dogs with cancer to those of normal dogs. Dogs with lymphoma (n = 50) and osteosarcoma (n = 52) were evaluated. Dogs with lymphoma had significantly lower (P = .0028) mean serum zinc concentrations (mean +/- SD; 1.0 +/- 0.3 mg/L) when compared to normal dogs (1.2 +/- 0.4 mg/L). Dogs with osteosarcoma also had lower mean serum zinc concentrations (1.1 +/- 0.4 mg/L), but this difference was not significant (P = .075). Serum chromium concentrations were significantly lower in dogs with lymphoma (2.6 +/- 2.6 microg/L, P = .0007) and osteosarcoma (2.4 +/- 3.1 microg/L, P = .0001) compared to normal dogs (4.7 +/- 2.8 microg/L). Serum iron concentrations and total iron-binding capacity were significantly lower in dogs with lymphoma (110.8 +/- 56.7 microg/dL, P < .0001, and 236.6 +/- 45.6 microg/dL, P < .0001, respectively) and osteosarcoma (99.6 +/- 49.3 microg/dL, P < .0001, and 245.0 +/- 43.8 microg/dL, P = .0011, respectively) when compared to normal dogs (175.1 +/- 56.7 microg/dL and 277.1 +/- 47.4 microg/dL). Mean ferritin concentration was significantly higher in dogs with lymphoma (1291.7 +/- 63.0 microg/L) than in normal dogs (805.8 +/- 291.1 microg/L, P < .0001) and dogs with osteosarcoma (826.5 +/- 309.2 microg/L, P < .0001). Further investigation is needed to explore the clinical significance of these mineral abnormalities in dogs with cancer.

Abstract
BACKGROUND Treatment coverage for mental disorders is poor in most developed countries. AIMS To explore some reasons for the poor treatment coverage for mental disorders in developed countries. METHOD Data were taken from Australian national surveys and from the World Health Report. RESULTS Only one-third of people with a mental disorder consulted. Probability of consulting varied by diagnosis: 90% for schizophrenia, which is accounted for by external factors; 60% for depression; and 15% for substance use and personality disorders. The probability of consulting varied by gender, age, marital status and disability, from 73% among women aged 25-54 years, disabled and once married to 9% among males without these risk factors. Those who did not consult but were disabled or comorbid said that they "preferred to manage themselves". Data from five countries showed no evidence that overall health expenditure, out-of-pocket cost or responsiveness of the health system affected the overall consulting rates. CONCLUSIONS Societal, attitudinal and diagnostic variables account for the variation. Funding does not. Public education about the recognition and treatment of mental disorders and the provision of effective treatment by providers might remedy the shortfall.

Abstract
BACKGROUND There is still a relative paucity of information about the long-term course of depression. METHODS Consecutive patients admitted to a teaching hospital psychiatry unit with symptoms of depression, previously assessed at 6 months and 2, 5 and 15 years after index admission, were reviewed at 25 years (N = 49, including eight informants of deceased probands, of an original 145 with major depression (DEPs)). Prospective psychiatric (N = 22) and retrospective surgical (N = 50) control groups assessed after 25 years were used for comparison. RESULTS A further decade of follow-up confirmed the chronicity of depression. Of depressed patients (DEPs) followed for the full 25-year-period only 12% of the 49 original DEPs recovered and remained continuously well, 84% experienced recurrences, 2% experienced an unremitting course and another 2% died by suicide. Note that in the first 15-year-period 6% (9/145 DEPs) committed suicide, a further 38 died and 32 were lost to follow-up. They experienced an average of three episodes of depression over the 25 years. In the decade since the 15-year follow-up, 27% improved in clinical outcome (including four of five previously chronically depressed patients), 55% remained unchanged and 18% worsened; and the number of episodes per year declined. Patients initially diagnosed with neurotic or endogenous depression had similar long-term outcomes. The criteria for a current DSM-III-R disorder were met by 37% of DEPs, including 11% with depression or dysthymia. On the global assessment of functioning scale 78% of the DEPs had some impairment compared to 62% of psychiatric controls and 40% of surgical controls. CONCLUSION Even after 25 years, severe depressive disorders appear to have poor long-term outcomes. Patients with chronic outcomes over 15 years can improve when followed over longer periods.

Abstract
OBJECTIVE The Global Burden of Disease study found mental disorders to be the world's leading cause of disability. Few studies have examined the validity of the novel approach used to estimate disability, the person trade-off preference method. This paper describes, and examines the validity of, the burden of disease person trade-off protocol. METHOD The person trade-off provides preferences for health states (how good or bad you think it is in relation to perfect health). General practitioners (n = 20) with training in mental health provided preferences for 19 mental disorders using the person trade-off method. Descriptions for the mental disorders were derived from the average symptom severity and disability observed in the Australian National Survey of Mental Health and Wellbeing. Validity was investigated by comparison with two other methods (rating scale and rank order). RESULTS The general practitioners found the person trade-off complex and affronting. Only a moderate concordance was observed with two validity comparisons; however, validity was significantly increased following the opportunity for group discussion among the clinicians. The disability weights were higher than those used in the global study, a possible consequence of differences in disorder descriptions. CONCLUSIONS The present study is limited by small subject numbers and by using only one type of key informant (clinicians). While this study provided some evidence for the validity of the person trade-off, it also echoes concerns from recent commentaries about the feasibility of this method. These concerns are particularly relevant for mental disorder burden, which relies heavily on the magnitude of the disability weights. Further work is required to ensure that disability burden is validly estimated, and thus can appropriately be used to inform mental health policy.

Abstract
OBJECTIVE To determine from self-report how often people with anxiety and depressive disorders consult GPs and what treatment they receive. DESIGN The study was derived from the 1997 Australian National Survey of Mental Health and Wellbeing. A probability sample of adults was interviewed to determine how many had which mental disorders, how disabled they were by those disorders, and what treatment they had received. PARTICIPANTS 10641 adults, a 78% response rate. MAIN OUTCOME MEASURES Prevalence of anxiety and depressive disorders and related disability; frequency of consultations for a mental problem; treatment received. RESULTS 13.6% of the population both met criteria for an anxiety or depressive disorder in the 12 months before the survey and, when they suffered from more than one disorder, nominated this as their principal complaint. They reported some disability in 7 of the previous 28 days, and consulted a GP or other health professional 1.4 times in that period. Over half did not seek a consultation for a mental health problem at any time during the year, many because they thought they had no need. CONCLUSION Many people who could benefit from treatment for anxiety and depressive disorders are not being reached. If people were registered with a general practice it would be possible for GPs to take a proactive stance that could result in greater benefit to patients at a lower cost to the health system.

Abstract
General measures of disablement are powerful tools in clinical settings as they provide a link between clinic and community populations and allow cross-disorder comparisons. Because of their generic nature, they allow the transmittal of comprehensible health planning information to decision makers. We located no studies of such general disability measures in the anxiety disorders and decided to examine the properties of three brief generic measures in an anxiety disorders clinic. Consecutive attenders (N=168) were administered the Medical Outcomes Study Short Form-12 item (SF-12), the Brief Disability Questionnaire (BDQ), and a measure of the number of disability days due to health over the past 4 weeks. These measures were compared on their ability to discriminate within the clinic and in comparison to a representative community group. The mental health scale of the SF-12 was the most sensitive of the generic measures to differences in functioning, and is recommended as a measure of such for people with anxiety disorders. Attenders at this anxiety clinic reported high levels of disablement, and normative data on the general measures are provided.

Abstract
BACKGROUND Cardiac complications occur commonly in vascular surgery patients. Diagnosis of cardiac complications is difficult because of the inaccuracies associated with traditional cardiac enzyme measurements. CTi, a highly sensitive and specific marker of myocardial injury, may be able to detect cardiac complications with greater ease and accuracy. METHODS The study prospectively examined 100 consecutive patients who underwent major vascular surgery between 6/7/98 and 31/12/98 at the Royal Brisbane Hospital. Daily measurements of cTi, creatine kinase (CK), creatine kinase MB (CKMB), CKMB index, renal function and haemoglobin were taken for three postoperative days. One postoperative electrocardiograph (ECG) was taken. An extensive cardiac history was taken. Intraoperative and postoperative events were recorded. FINDINGS There were 100 patients. 18 patients (18%) had a cTi elevation. On the basis of classical diagnostic criteria, 15 patients (15%) suffered one or more cardiac complication (either myocardial infarction, congestive cardiac failure, unstable angina or atrial fibrillation). One patient (1%) who had a cTi elevation died. CTi elevation occurred in five patients (5%) who were not diagnosed with cardiac complications based on traditional criteria. Despite not meeting specific diagnostic criteria for cardiac complications, all patients showed signs and symptoms that could be attributed to myocardial ischaemia. Every patient who developed congestive cardiac failure or atrial fibrillation had a cTi elevation. A Chi-square analysis revealed a significant association between cTi elevation and postoperative cardiac complications. Four variables contributed small but significant amounts of unique variance to the prediction of peak cTi on linear regression analysis. These were peak CKMB index, postoperative congestive cardiac failure, postoperative chest pain and postoperative cardiac complications. CONCLUSIONS Routine cTi monitoring of postoperative vascular patients would be an effective and inexpensive way to detect patients with cardiac complications. The relationship between postoperative cTi elevation and significant coronary artery disease remains to be shown.

Abstract
A randomised controlled trial was planned to compare two different treatment strategies--structured problem solving and selective serotonin reuptake inhibitor (SSRI) medication--for patients with mild to moderate major depression. The trial was to be conducted in the primary care setting with all treatment given by general practitioners. When no patients had been recruited into the study after six months, we performed an audit of all patients with depressive symptoms attending the doctors' practices over three weeks. Exclusion criteria were changed to ease entry into the trial, but still no patients were recruited over the following six months. What went wrong?

Abstract
BACKGROUND Health planning should be based on data about prevalence, disability and services used. AIMS To determine the prevalence of ICD-10 disorders and associated comorbidity, disability and service utilisation. METHOD We surveyed a national probability sample of Australian households using the Composite International Diagnostic Interview and other measures. RESULTS The sample size was 10 641 adults, response rate 78%. Close to 23% reported at least one disorder in the past 12 months and 14% a current disorder. Comorbidity was associated with disability and service use. Only 35% of people with a mental disorder in the 12 months prior to the survey had consulted for a mental problem during that year, and most had seen a general practitioner. Only half of those who were disabled or had multiple comorbidity had consulted and of those who had not, more than half said they did not need treatment. CONCLUSIONS The high rate of not consulting among those with disability and comorbidity is an important public health problem. As Australia has a universal health insurance scheme, the barriers to effective care must be patient knowledge and physician competence.

Abstract
Compared with countries worldwide, the United States currently has one of the lowest peritoneal dialysis (PD) populations as compared with its hemodialysis (HD) population. Approximately 12% of the total dialysis population in the United State is on PD. This figure correlates with the take-on rate [percentage of end-stage renal disease (ESRD) patients enrolling in PD programs] of about 12%-15% in the United States. Over a two-year period, we prospectively examined the role that developing a comprehensive infrastructure and support system had on expanding our PD program. The changes made included these: nephrologists placing PD catheters using the laparoscopic method; active identification of, and training for, family members and personnel in nursing homes and daycare centers to perform PD; improvements in home conditions through support by social workers; early ESRD patient education; and provision of in-center intermittent PD (IPD) for selected patients. We then compared the results from the two years after commencement of the changes against the two years before the changes were made. Training of personnel in nursing homes increased enrollment from 3 to 11 patients (p = 0.01); training of personnel in daycare centers increased enrollment from 0 to 5 patients (p = 0.05); training family members and providing family support increased enrollment from 4 to 15 patients (p = 0.03); early patient and family education increased enrollment from 4 to 24 patients (p = 0.008); improving home conditions increased enrollment from 1 to 14 patients (p = 0.01); and providing an IPD program for selected patients added 6 patients (p = 0.05). Introducing a program for nephrologists to place PD catheters by the laparoscopic technique decreased catheter mechanical failure (and subsequent transfer to HD), from 22 to 3 patients (p = 0.005). Our PD take-on rate (percentage of ESRD patients choosing PD modality) increased from 19% to 76% (p = 0.002). The total number of patients in the PD program over the two years after initiation of the changes increased from 33 to 93 (p = 0.01), while the number of HD patients decreased from 168 to 142 (p = 0.05). Developing a comprehensive infrastructure and support system for PD programs permits enrollment of patients who otherwise would have been excluded as PD candidates and eliminates loss of PD patients to HD. Implementation of such programs can contribute considerably to enhancing the PD population growth rate.

Abstract
BACKGROUND It is commonly assumed that diagnoses according to DSM-IV and ICD-10 are equivalent. Recent discussions on generalized anxiety disorder (GAD) have suggested that ICD-10 criteria may be identifying a milder form of the disorder than DSM-IV. This report examines prevalence and associated disability of DSM-IV and ICD-10 GAD. METHODS The Composite International Diagnostic Interview was administered to a community sample of 10,641 people, and the diagnostic criteria that contributed to discrepancies between DSM-IV and ICD-10 GAD were identified. A multiple linear regression analysis was carried out to determine the strength of the relationship between disability, as measured by the SF-12, and discrepant diagnoses of GAD. RESULTS The concordance between DSM-IV and ICD-10 GAD was fair (kappa = 0.39). The two sources of discrepancy when DSM-IV was positive and ICD-10 was negative resulted from the requirement in ICD-10 that the respondent endorse symptoms of autonomic arousal (ICD-10 criterion B) and the requirement that ICD-10 GAD does not co-occur with panic/agoraphobia, social phobia or obsessive-compulsive disorder (ICD-10 criterion C). The two major sources of discrepancy when ICD-10 was positive and DSM-IV was negative resulted from the requirement in DSM-IV that the worry be excessive (DSM-IV criterion A) and that it causes clinically significant distress or impairment (DSM-IV criterion E). DSM-only GAD cases had significantly higher levels of disability than ICD-only cases of GAD after controlling for demographic variables and the presence of comorbid psychiatric disorders. CONCLUSIONS While the prevalence rates for DSM-IV and ICD-10 GAD are almost identical, these classification systems are diagnosing different groups of people.

OBJECTIVE To outline the utility of the Composite International Diagnostic Interview (CIDI) in the diagnosis of psychosis. METHOD Report current situation. RESULTS The CIDI was designed as a fully structured interview to be used by lay interviewers. It generates false positive diagnoses in community surveys and false negative diagnoses in psychiatric settings. A new psychosis module has been developed to reduce these problems. CONCLUSIONS The diagnosis of psychosis by fully structured diagnostic interviews is difficult.

Abstract
BACKGROUND Anxiety disorders are common and disabling. Yet they often go unnoticed: sufferers do not always complain of symptoms, and when they do they often present with primarily somatic concerns. Also, they are sometimes dismissed as being 'just anxious', 'very shy', or 'worriers' rather than being recognized as suffering from very treatable disorders. OBJECTIVE To briefly describe the assessment, diagnosis, differential diagnosis, and management of the major anxiety disorders. DISCUSSION Anxiety disorders are common and treatable. Cognitive behavioural therapy and medications are the two main treatment modalities. Ways of increasing skills with psychological techniques are also discussed.

OBJECTIVES The objectives of this study were to estimate the 1-month and 1-year prevalence of mental disorders in the Australian adult population; to determine the amount of disablement associated with this; and to determine the use of health and other services by persons with common mental disorders. METHOD For the Adult Survey, a household sample of 10600 persons aged 18 years and over were interviewed across Australia by experienced field staff of the Australian Bureau of Statistics. This was 78% of the target sample. The interview consisted of the composite international diagnostic interview in its automated presentation (CIDI-A) and other components to determine disablement, use of services and satisfaction with services received. The diagnostic classifications used in the analyses were both ICD-10 and DSM-IV. Only the results from ICD-10 are reported here. RESULTS A total of 17.7% of the sample had one or more common mental disorders, anxiety, depression, alcohol or substance abuse and neurasthenia. This morbidity was associated with considerable disablement in daily life: 3 days of impaired social role performance in the previous 4 weeks, compared with 1 day for the general population. Of all cases, 64.6% had had no contact with health services in the previous year; 29.4% had seen GPs and 7.5% had seen psychiatrists. CONCLUSION Australia now has its own national estimates of psychiatric morbidity. The morbidity is associated with considerable disablement, but most of it is untreated. General practitioners encounter by far the largest proportion of those reaching services.

Abstract
The past decade has seen major advances in contraceptive technology. These have resulted in the launch of several new highly effective methods of contraception and also significant improvements in existing methods. The main purpose of this article is to review how the contraceptive field has changed over the past 10 years, explain the new methods that have become available, e.g. hormone-releasing intrauterine systems, hormone implants and female condoms, re-examine existing methods, and mention new research and how this has affected clinical practice over the past decade. When discussing contraception, clients should be given up-to-date and accurate information on currently available methods: their efficacy, advantages, disadvantages and how the method works. As with any other specialty in medicine, nurses offering contraceptive advice should ensure they regularly update their knowledge and are aware of new developments and research in order to facilitate their clients in making an informed choice. New research and developments affect the choices and potentially the health of a large part of the population.

Abstract
The study objective was to identify a set of personality disorder (PD) criteria from the DSM PD diagnostic sets that can be used to detect subjects with an increased likelihood of having a PD diagnosis. In a series of outpatients evaluated systematically in two waves for every criteria item for 12 DSM-III-R PDs, stepwise logistic regression identified 45 criteria as discriminative for their specific PDs, which are selected for further analysis to assess their ability to discriminate for any PD. Receiver operating characteristic (ROC) analysis is used to evaluate their discriminative power in an independent conjoined sample (N = 1,342) from six centers that assessed every PD criteria item by structured instrument (Structured Clinical Interview for DSM-III-R PDs [SCID-II, Personality Disorder Examination [PDE], and Structured Interview for DSM-III-R PDs [SIDP-R]). The cutoff that maximizes information gain is used to determine the diagnostic threshold (DT). Initially, 15 of 45 criteria are identified. At the 0.43 PD prevalence, a DT of 2 or more of the 15 PD criteria across samples is optimal. The maximum information gain (MIG) is .42 bits, and the AUR is 0.94+/-.007. Other performance indices at this cutoff are .90 sensitivity, .84 specificity, .81 positive predictive power (PPP), .91 negative predictive power (NPP), and .86 hit rate (HR). Taken collectively, the 15 PD criteria selected by the data reduction techniques suggest a narrowed set to be assessed in screening for the presence or absence of any PD with comparable or better psychometric properties than other tests routinely used for diagnosing medical and psychiatric disorders. If specific PD categorization is needed, a second-step comprehensive assessment should follow.

Abstract
Why does the burden of mental disorders persist in established market economies? There are four possibilities: the burden estimates are wrong; there are no effective treatments; people do not receive treatment; or people do not receive effective treatments. Data from the Australian National Survey of Mental Health and Wellbeing about the two commonest mental disorders, generalized anxiety disorder and depression, have been used in examining these issues. The burden of mental disorders in Australia is third in importance after heart disease and cancer, and anxiety and depressive disorders account for more than half of that burden. The efficacy of treatments for both disorders has been established. However, of those surveyed, 40% with current disorders did not seek treatment in the previous year and only 45% were offered a treatment that could have been beneficial. Treatment was not predictive of disorders that remitted during the year. The burden therefore persists for two reasons: too many people do not seek treatment and, when they do, efficacious treatments are not always used effectively.

Abstract
BACKGROUND Lifetime rates of depression reported in epidemiological surveys are generally only twice the 12 month rates. Either people forget the symptoms of depression or many people who have a depressive episode remain depressed for many years. Both may be true. There is a need to examine the long-term clinical validity of interviews that are used to make lifetime diagnoses. METHODS Forty-five patients who were part of a long-term follow-up study of depression were interviewed 25 years after the index episode. The diagnoses from the original, fully structured interviews were compared with the responses people made for that period when interviewed using the CIDI 25 years later. RESULTS Twenty-seven patients met CIDI DSM-III-R criteria for depression at index episode. At the 25 year follow-up, 19 of the 27 reported the essential symptoms of 'depression or loss of interest' being present at the index time, and in 14 of the 27 the depressive symptoms recalled met criteria for DSM-III-R major depressive episode at that time. CONCLUSIONS Seventy per cent of people who were hospitalized for a major depressive episode can recall being depressed but only half can recall sufficient detail to satisfy the diagnostic criteria when interviewed 25 years later. As depressive episodes, especially those severe enough to warrant admission, are recalled better than many other diagnoses, one must be cautious about the lifetime rates for mental disorders reported in retrospective epidemiological surveys.

Abstract
OBJECTIVE The aim of this paper is to review the status of treatments in psychiatry. METHOD The criteria for good treatment are defined and then treatments in psychiatry are examined for efficacy, effectiveness and efficiency. RESULTS A large number of treatments were listed by Nathan and Gorman as having satisfied the criteria for efficacy: that is, they had been shown to be superior to placebo in randomised controlled trials. The problem of effectiveness (does the treatment still work when used by the average clinician with the average patient?) is a general one in medicine, but the evidence in psychiatry is not outstanding. The problem of efficiency (what level of resources are required to produce benefit?) is being addressed in a piecemeal fashion, and again this is no different to the situation in general medicine. CONCLUSIONS A considerable number of treatments have been shown to satisfy the criteria for efficacy. Effectiveness requires that psychiatrists apply such proven treatments and demonstrate benefit through the use of outcome measurement. A system that separated the health budget into segments for prevention, cure and care might ensure that these three goals were pursued equitably and efficiently.

Abstract
The assumption that participants receiving an ICD10 diagnosis of posttraumatic stress disorder (PTSD) will also receive a DSM-IV diagnosis of PTSD was tested. Data were gathered for 1,364 participants using the Composite International Diagnostic Interview (CIDI). The 12-month prevalence of PTSD was 3% for DSM-IV and 7% for ICD10 Diagnostic Criteria for Research (ICD10-DCR). The agreement between the two systems was fair (kappa = .50). Forty eight percent of the discrepancies between the systems were accounted for by the additional criterion requiring clinically significant distress or impairment included in DSM-IV. The inclusion of symptoms of general numbing of responsiveness accounted for 18% of the discrepancies. It is concluded that ICD10-DCR PTSD cannot be assumed to be identical to DSM-IV PTSD.
