The many similarities between the metabolic syndrome and Cushing's syndrome led to the hypothesis that excess glucocorticoids (GC) are part of the pathogenesis linking their features. We review recent work that confirms the initial similarities (obesity, glucose intolerance, hypertension, and hyperlipidemia) and extends them to associated features of both syndromes (osteopenia, hypogonadism, leukocytosis, depression, and muscle weakness). Recent studies report that these features also occur in subclinical Cushing's syndrome, hypercortisolemic depression, and the transgenic overexpression of 11beta-hydoxysteroid dehydrogenase type 1 (11beta-HSD1) in mouse models of excess GC in adipose tissue. Reducing excess GC--in the clinical syndromes and in the mouse model-reverses many of these features. Because local tissue excess GC may have a central role in the pathogenesis of the metabolic syndrome, selective 11beta-HSD1 inhibitors are under active development by several pharmaceutical companies.

Hypothyroidism is a common disease that is often undiagnosed or misdiagnosed because the signs and symptoms are often confused with other conditions. These conditions include hyperlipidemia, depression, various gynecologic conditions, and even the normal aging process. While overt hypothyroidism is usually easily recognized, individuals with mild thyroid failure often present a greater diagnostic and therapeutic challenge.

This article discusses the use of integrated care models, in particular, collaborative care, in the treatment of bipolar disorder. Dr. Williams first discusses how care delivered via a collaboration between primary care and psychiatric providers has the potential to improve both mental health and general medical outcomes for patients with bipolar disorder. He describes promising findings from studies of the use of collaborative care in the treatment of depression, an area where this model has received the most study. Dr. Williams then discusses how such collaborative care models might best be implemented in the treatment of bipolar disorder. In the second half of the article, Dr. Manning focuses on five key issues that are an especially appropriate focus for collaborative care for bipolar disorder and for which the STAndards for BipoLar Excellence (STABLE) Project developed quality improvement performance measures: assessment for risk of suicide, assessment for substance use/abuse, monitoring for extrapyramidal symptoms, monitoring of metabolic parameters (e.g., monitoring for weight gain, hyperglycemia, hyperlipidemia), and provision of bipolar-specific psychoeducation.

Nationally representative data on the quality of care for obese patients in US-ambulatory care settings are limited. We conducted a cross-sectional analysis of the 2005 and 2006 National Ambulatory Medical Care Survey (NAMCS). We examined obesity screening, diagnosis, and counseling during adult visits and associations with patient and provider characteristics. We also assessed performance on 15 previously published ambulatory quality indicators for obese vs. normal/overweight patients. Nearly 50% (95% confidence interval (CI): 46-54%) of visits lacked complete height and weight data needed to screen for obesity using BMI. Of visits by patients with clinical obesity (BMI >or=30.0 kg/m(2)), 70% (66-74%) were not diagnosed and 63% (59-68%) received no counseling for diet, exercise, or weight reduction. The percentage of visits not being screened (48%), diagnosed (66%), or counseled (54%) for obesity was also notably higher than expected even for patients with known obesity comorbidities. Performance (defined as the percentage of applicable visits receiving appropriate care) on the quality indicators was suboptimal overall. In particular, performance was no better than 50% for eight quality indicators, which are all related to the prevention and treatment of obesity comorbidities, e.g., coronary artery disease, hypertension, hyperlipidemia, asthma, and depression. Performance did not differ by weight status for any of the 15 quality indicators; however, poorer performance was consistently associated with lack of height and weight measurements. In conclusion, many opportunities are missed for obesity screening and diagnosis, as well as for the prevention and treatment of obesity comorbidities, in office-based practices across the United States, regardless of patient and provider characteristics.

Attention to the role of n-3 long-chain fatty acids in human health and disease has been continuously increased during recent decades. Many clinical and epidemiologic studies have shown positive roles for n-3 fatty acids in infant development; cancer; cardiovascular diseases; and more recently, in various mental illnesses, including depression, attention-deficit hyperactivity disorder, and dementia. These fatty acids are known to have pleiotropic effects, including effects against inflammation, platelet aggregation, hypertension, and hyperlipidemia. These beneficial effects may be mediated through several distinct mechanisms, including alterations in cell membrane composition and function, gene expression, or eicosanoid production. A number of authorities have recently recommended increases in intakes of n-3 fatty acids by the general population. To comply with this recommendation a variety of food products, most notably eggs, yogurt, milk, and spreads have been enriched with these fatty acids. Ongoing research will further determine the tissue distribution, biological effects, cost-effectiveness, and consumer acceptability of such enriched products. Furthermore, additional controlled clinical trials are needed to document whether long-term consumption or supplementation with eicosapentaenoic acid/docosahexaenoic acid or the plant-derived counterpart (alpha-linolenic acid) results in better quality of life.

Cardiovascular disease (eg, myocardial infarction, ischemic stroke) is the leading cause of death in patients who have metabolic syndrome and diabetes mellitus. By effectively treating the whole patient, however, the risk of death from cardiovascular disease can be reduced or prevented. The author describes clinical approaches for achieving this goal. He reviews information that is useful to know about patients regarding modifiable and potentially modifiable risk factors for cardiovascular disease, including hypertension, hyperlipidemia, smoking, activity levels, dietary habits, obesity, carotid artery stenosis, and atrial fibrillation. He also notes the importance of evaluating patients for relevant psychosocial factors such as depression. Finally, the author analyzes treatment options for patients, including effective medications, dietary modification, and exercise-emphasizing the use of pedometers-as well as participation by patients in weight-control support groups.

Migraine, especially migraine with aura (MA), is an established risk factor for ischemic lesions of the brain. Recent evidence has also linked migraine to a broader range of ischemic vascular disorders including angina, myocardial infarction, coronary revascularization, claudication, and cardiovascular mortality. The mechanisms which link migraine to ischemic vascular disease remain uncertain and are likely to be complex. Cortical spreading depression, the presumed substrate of aura, may directly predispose to brain lesions and that would explain why MA is consistently demonstrated as a risk factor for cerebral ischemia, while for migraine without aura (MO), the evidence is less consistent. Additionally, individuals with migraine have a higher prevalence of risk factors known to be associated with cardiovascular disease (CVD), including hypertension, diabetes, and hyperlipidemia. The increased prevalence of CVD risk factors is also higher for MA than for MO. Since the evidence linking migraine and CVD is getting robust, neurologists should be aware of this association. Individuals with MO seem to be at little increased risk of CVD. MA is associated with an increased risk of ischemic stroke and likely also for other ischemic CVD events. Accordingly, heightened vigilance is recommended for modifiable cardiovascular risk factors in migraineurs, especially with MA. Ultimately, it will be important to determine whether MA is a modifiable risk factor for CVD and if preventive medications for migraine or antiplatelet therapy might reduce the risk of CVD in patients with MA.

Family physicians have an essential role in assessing, identifying, treating, and preventing or delaying vision loss in the aging population. Approximately one in 28 U.S. adults older than 40 years is visually impaired. Vision loss is associated with depression, social isolation, falls, and medication errors, and it can cause disturbing hallucinations. Adults older than 65 years should be screened for vision problems every one to two years, with attention to specific disorders, such as diabetic retinopathy, refractive error, cataracts, glaucoma, and age-related macular degeneration. Vision-related adverse effects of commonly used medications, such as amiodarone or phosphodiesterase inhibitors, should be considered when evaluating vision problems. Prompt recognition and management of sudden vision loss can be vision saving, as can treatment of diabetic retinopathy, refractive error, cataracts, glaucoma, and age-related macular degeneration. Aggressive medical management of diabetes, hypertension, and hyperlipidemia; encouraging smoking cessation; reducing ultraviolet light exposure; and appropriate response to medication adverse effects can preserve and protect vision in many older persons. Antioxidant and mineral supplements do not prevent age-related macular degeneration, but may play a role in slowing progression in those with advanced disease.

Psoriasis is a chronic inflammatory skin disease. Associated comorbidities or risks may include psoriatic arthritis, obesity, depression, smoking, diabetes, hyperlipidemia, an increased risk of cardiovascular disease with myocardial infarction, or an increased risk of lymphoma. The clinical presentation of psoriasis can range from the more common red scaling elevated plaques on the elbows, knees, or scalp to the less common superficial pustules scattered on the palms or soles, or in rare cases wide-spread pustules on the body. More specifically, the clinical spectrum of psoriasis includes the plaque, guttate, small plaque, inverse, erythrodermic, and pustular variants. The determinants of the clinical severity of psoriasis, the risk of comorbidities, and the quality of life of a psoriatic patient are influenced by multiple factors. At the minimum, these include variations in the quality and type of psoriasis, the quantity of skin involved, and the distribution of skin lesions (including special areas such as the scalp, nails, face, intertriginous regions, and palmoplantar surfaces). Objective measures used to quantify the severity of psoriasis, including the body surface area involved, Physician's Global Assessment, Psoriasis Area and Severity Index, and quality of life measures, are all assessments that can be useful in guiding approaches to management and therapeutics. In this paper, we review the clinical spectrum of psoriasis, the differential diagnoses, measures and determinants of severity, and the recommendations on when to refer a patient to a specialist in psoriasis. We also briefly review the comorbidities, and note the importance of referring the psoriatic patient to the internist/general practitioner for evaluation and management for these comorbidities.

Obesity continues to be a serious cause of morbidity and mortality globally and particularly in North America. Primary manifestations of obesity include obstructive sleep apnea (OSA) and depression associated with a decrease in immune defense mechanisms, possibly related to increased cytokine levels. Secondary manisfestations of obesity possibly result from a cascade of events and include insulin resistance/ hyperglycemia, hyperlipidemia, and hypertension-all of which comprise metabolic syndrome. This paper reviews sleep disturbances in general and OSA in psychiatric patients, particularly those who are obese.
