This article summarizes the features of posttraumatic stress disorder (PTSD) that may affect treatment outcome and discusses the areas in which treatment outcome can be productively evaluated. PTSD is a complex psychiatric condition that tends to run a chronic course. Measurement of treatment outcome in PTSD is confounded by multiple factors, including a high prevalence of comorbid disorders, reactivation of the syndrome by ongoing environmental stressors, spontaneous recovery of the early disorder, and a fluctuating course of the chronic disorder. Four principal domains of treatment outcome may be evaluated in PTSD: core symptom severity, comorbid conditions (particularly depression), adverse practices (e.g., violence or alcohol consumption), and social/vocational disability. To gain an accurate assessment of these domains, a comprehensive assessment battery is needed. The relevant instruments and their yield in studies of PTSD are reviewed.

There seems to be a lack of understanding between practitioners and patients on the topic of insomnia. One adult out of four complains of insomnia; however only one insomniac out of four has ever complained about it to their practitioner during a visit made for another problem and only one out of twenty has come to discuss specifically the problem of his or her insomnia. Only a few patients with insomnia take a treatment for it. This gap between the patient's feeling and the practitioner's answer has to be better understood if we want to know why insomnia seems to be so prevalent and what impact it has on society. One aspect may be a question of definition. Insomnia may be considered an ordinary complaint (after one poor night) or as a chronic disease. Practitioners have poor knowledge about sleep disorders and may be embarrassed about coping with an impairment they never specifically learned to manage. The second aspect concerns the impact of insomnia on daytime alertness and performance. While patients usually complain of an impaired daytime functioning with a feeling of fatigue, sleepiness, and risk of mistakes, many studies of insomniacs do not reveal any increased sleepiness or decrease of performance (measured by objective tests) the day following a poor night. Practitioners may therefore find it difficult to understand the real impact of insomnia on daytime functioning. The third aspect is related to the large co-morbidity between insomnia and psychiatric diseases, especially depression and anxiety. It does make it harder for practitioners to define whether the sleep impairment suffered by their patient is the cause for other symptoms or the consequence of an underlying disease. Thus, it makes it all the more difficult for the practitioner to determine which treatment is the most appropriate. These aspects have to be clarified if one wants to estimate the real impact of insomnia on society. It could be useful to both practitioners and patients to have a better understanding on the relationship between poor sleep and daily lives.

In December 1997, public health units in Ontario received revised mandatory program guidelines from the Ministry of Health in advance of the downloading of public health to municipalities. Public health units face difficult decisions in allocating municipal resources to meet the Province's mandated programs. To set priorities for resource allocation, it is critical to assess need across program areas and to use a common unit in doing so. This paper applies the Healthy Life Years (HeaLYs) method in assessing health need related to the mandatory programs for the population of Wellington and Dufferin counties in Ontario. The HeaLYs method incorporates duration and severity of ill-health, incidence and mortality in calculating years of healthy life lost (YHLL). For Wellington-Dufferin, the leading causes of YHLL were concentrated in the program areas of chronic disease, injury, and substance abuse and included four areas not addressed in the MPG (suicide, depression, dementia, and osteoarthritis).

Multiple sclerosis (MS) is a chronic disease of the central nervous system without a known cure. Thus the role of complementary and alternative therapies (CATs) for the management of symptoms lies in palliative care and this is borne out by the popularity of these treatments amongst MS sufferers. This review is aimed at determining whether this use is supported by evidence of effectiveness from rigorous clinical trials. Database literature searches were performed and papers were extracted in a pre-defined manner. Twelve randomized controlled trials were located that investigated a CAT for MS: nutritional therapy (4), massage (1), Feldenkrais bodywork (1), reflexology (1), magnetic field therapy (2), neural therapy (1) and psychological counselling (2). The evidence is not compelling for any of these therapies, with many trials suffering from significant methodological flaws. There is evidence to suggest some benefit of nutritional therapy for the physical symptoms of MS. Magnetic field therapy and neural therapy appear to have a short-term beneficial effect on the physical symptoms of MS. Massage/bodywork and psychological counselling seem to improve depression, anxiety and self-esteem. The effectiveness for other CATs is unproven at this time. In all the CATs examined further investigations are needed in the form of rigorous large-scale trials.

Recognition of depressive and anxiety disorders in adolescents reduces morbidity, mortality, and lifetime risk for psychiatric illness and maladaptive behaviors. Effective treatments for these disorders are available and are associated with minimal severe side effects. Because adolescents tend to underreport their psychologic distress, screening for these disorders in the primary care setting is incumbent on the clinician. Depression or anxiety may be a primary or a secondary condition--with each other and with other medical illness. Substance abuse, including cigarettes, should not be overlooked as an accompanying risk factor for poor health care habits and as an indicator of degree of family (lack of) support. Adolescents at risk should be screened and their symptoms taken seriously. This brief overview does not focus on the need for primary care clinicians to seek assistance and support of psychiatrists in the diagnosis and development of treatment algorithms. All clinicians should be reminded that judgments about peoples' internal mental states and function are difficult to assess objectively and with compassion. Initial assessment in the primary care setting should include a telephone consultation with a reliable psychiatric colleague and referral for more in-depth evaluation in the event of more complicated course. These disorders need to be treated comprehensively because of the lifelong implications that having a chronic disease bear on the individual and his or her physiology. Primary care clinicians are pivotal instruments in engaging adolescents to embrace appropriate therapeutic measures for their current and future health.

Is the patient going to die of cancer or with cancer? Is the patient going to suffer pain and disability due to cancer? Is the patient able to tolerate aggressive life-prolonging treatment? This paper tries to reply to the fundamentals of these questions by introducing the multidimensional assessment that evaluates areas where age-related changes are more likely. Chronologic age cannot be used to predict the degree of comorbidity and of functional deterioration of the single individual up to age 85 at least. Assessment of aging includes health, functional status, nutrition, cognition, socio-economic and emotion evaluations. This multidisciplinary assessment is referred to as comprehensive geriatric assessment (CGA). The risk of comorbid conditions increases with age and may result in underdiagnosis: in older patients, new symptoms may not be clearly recognized by the patient and may be dismissed by practitioners as manifestations of preexisting conditions. A meaningful assessment of comorbidity may be obtained with a comorbidity index. The Charlson scale and the Chronic Illness Rating Scale - Geriatric (CIRS-G), have enjoyed the widest acceptance. The Instrumental Activities of Daily Living (IADL) and the Activities of Daily Living (ADL) are the most sensitive assessment of function in older individuals. IADLs include shopping, managing finances, housekeeping, laundry, meal preparation, ability to use transportation and telephone and ability to take medications: in simple words, the IADLs are those skills a person needs to live independently. ADLs include feeding, grooming, transferring, toileting and are the skills necessary for basic living. Though a correlation exists among comorbidity, performance status, ADL and IADL, this correlation is not strong enough to be reflected in a single parameter. The Folstein Mini Mental Status (MMS), is the instrument of most frequent use to screen older individuals for dementia. The main problem with the MMS is lack of sensitivity to early stages of dementia. The Geriatric Depression Scale (GDS), a simple tool that can be completed by most patients at home, doubles the rate of detection of depression. The Mini Nutritional assessment is very sensitive to screen older persons for malnutrition. The risk of polypharmacy increases with age and partly results from the fact that older patients visit different practitioners. A CGA should also include evaluation of the so called Geriatric Syndromes like delirium, incontinence, osteoporosis, all of which represent a hallmark of frailty. The CGA may help the management of older individuals with cancer in at least three areas: detection of frailty, treatment of unsuspected conditions, removal of social barrier to treatment.

Depression is a very costly chronic disease. An important cost driver is treatment failure caused by patient noncompliance due, in part, to the adverse effects of medications. Additionally, inadequate duration of therapy and inappropriate medication switching contribute to the high cost of treatment. With the epidemiological data for depression demonstrating a rise in both incidence and prevalence over the last 20 years, and the fact that many of the newer antidepressants will see patent expiry in the near future, previous antidepressant cost-effectiveness scenarios are likely to change. As economic models play an increasingly important role in therapeutic decision-making, clinicians are encouraged to understand the strategies and methods involved in modelling antidepressant therapy. The aim of this review of the literature and synthesis of the various techniques important to the modelling of antidepressant therapies is for the practitioner to gain an increased understanding of the modelling methods previously utilised and be in a position to better evaluate future health economic models for the treatment of depression.

The relationship between characteristics of benzodiazepine exposure and health-status was examined in order to investigate risk profiles of benzodiazepine users. In the only pharmacy of a Dutch community of 13,500 inhabitants, all current benzodiazepine users that presented with a benzodiazepine prescription in November 1994 were invited to participate. On the basis of the RAND-36 questionnaire, summary scores for both physical and mental health were calculated, the Physical Component Summary (PCS) and the Mental Component Summary (MCS). After dichotomization with a cut-off point indicating seriously impaired health and after the combination of the PCS and MCS, four different categories of health status could be identified. We used logistic regression to study the relation between these four different groups with respect to benzodiazepine exposure. In total a group of 360 current benzodiazepine users was studied. Results showed that almost one-third of the participants had no significant impaired health; this group was further classified as reference group. We classified three other groups: one with physical problems (31%), one with mental problems (18%), and one with a combination of the two (22%). Multivariate analysis showed differences in risk factors for an impaired health status. The group with impaired physical health was associated with self-reported indication for muscle relaxation, hypnotic use, and a high CDS (Chronic Disease Score). The group with impaired mental health was associated with more frequent consulting of a mental health care specialist and with a low sense of self-efficacy. The group with both impaired physical as well as mental health was associated with a higher incidence of widowhood, a lower sense of self-efficacy, a high CDS, using benzodiazepines more than prescribed, and reporting depression as reason for their benzodiazepine use. In particular, two groups need critical examination: a group of apparently healthy users with long-term benzodiazepine use; and a frail group with impaired physical and mental health and using a higher dose than prescribed. Patient counseling and management of these four groups can be tailored to the specific needs of each group.

Asthma is the most common chronic disease in adolescents. Despite advances in the understanding of this disease and the availability of more specific treatment, the prevalence of asthma and its morbidity and mortality are increasing. This trend is especially prominent and worrisome in the age group that includes adolescents and young adults. Possible factors contributing to this significant problem in adolescents include a lack of knowledge about the disease, delays in seeking medical attention due to denial of symptoms or overuse of acute relief medication that mask the progression of the inflammation, and various psychological problems such as low self-esteem or depression. These factors, in addition to the typical developmental behaviors recognized in adolescence, contribute to the complexity of asthma management in this age group. This article comprehensively reviews the pathophysiology and precipitating factors of asthma as well as all aspects of medical care of affected individuals, including monitoring and self-care.

The prognostic value of physical health for changes in anxiety symptoms in older people was investigated in a prospective longitudinal study design with data from the Longitudinal Aging Study Amsterdam (LASA). In a sample of 2165 older (> 55 yrs.) respondents anxiety symptoms were measured twice over a three year interval with the anxiety subscale of the Hospital Anxiety and Depression Scale (HADS-A). Utilizing a cut-off value of 4 on the HADS-A, subjects were considered as anxious or as non-anxious. Based on the first assessment two groups were formed: subjects with and subjects without anxiety symptoms. In the non-anxious cohort the effect of physical health on the development of anxiety symptoms was studied; in the anxious cohort the same factors were evaluated on their predictive value for chronicity of anxiety. Indices of physical health included the presence of chronic diseases, functional limitations, and self-perceived health at the first assessment and changes on these variables over time. Results revealed that poor self-perceived health was predictive of incidence (OR = 1.5; 95% CI = 1.3-1.8) and chronicity of anxiety (OR = 1.2; CI = 1.0-1.5). Regarding chronic diseases, the results showed that suffering from more than one chronic disease predicted becoming anxious and chronicity of anxiety (OR = 1.7; CI = 1.2-2.5 and OR = 2.2; CI = 1.3-3.6, respectively). Specific chronic diseases were not strongly related to a change in anxiety levels. Thus, somatic diseases not only lead to depression, a finding reported in numerous studies, but also increase the likelihood of anxiety symptoms at a later point in time.
