ReviewAn approach to the patient with cognitive impairment: delirium and dementia.
Patients with cognitive impairment can be divided into 2 broad groups: those with chronic cognitive decline (most likely diagnosable with a dementia) and those with acute cognitive changes (most likely experiencing a delirium). However, diagnosis in clinical practice is far more complicated than it is in textbooks. ⋯ Unfortunately, the cognitively impaired patient is most often unable to provide such a history, and in the absence of a reliable family member, friend, or caregiver to fill in the gaps, diagnostic clarity can be difficult to achieve. This article outlines the broad diagnostic spectra of delirium and dementia, reviews current understanding of their pathogenesis, and discusses useful diagnostic and therapeutic techniques.

ReviewAn approach to the patient in crisis: assessments of the risk of suicide and violence.
Suicide is one of the leading causes of death in the United States and is defined as intentional self-harm with the intent of causing death. Various mental disorders may be a cause for increased violence. This article outlines the elements of the risk assessment (for harm to self and/or others) in patients in crisis and addresses which contributing factors may be modifiable. This article also proposes a practical framework for the management of risk regarding suicide and violence.

ReviewAn approach to the patient with dysregulated mood: major depression and bipolar disorder.
Major depressive disorder (MDD) and bipolar disorder are chronic relapsing-remitting illnesses whose effects on mood, behavior, and thinking exact a heavy toll on patients' physical and mental health and on their capacity for satisfying relationships and employment. In the inpatient setting, these affective illnesses and their treatments can complicate the diagnosis, course, therapy, and prognosis of numerous medical conditions. In this article, the authors discuss a general approach for general internists, family practitioners, and other primary care providers to follow in caring for patients with suspected MDD or bipolar disorder.

Obstructive sleep apnea (OSA) may be associated with myriad clinical consequences such as increased risk of systemic hypertension, coronary vascular disease, congestive heart failure, cerebrovascular disease, glucose intolerance, impotence, obesity, pulmonary hypertension, gastroesophageal reflux, and impaired concentration. Nonetheless, OSA remains undiagnosed in 82% of men and 93% of women with the condition. Early identification and treatment of OSA provides significant relief for individuals, prevents complications of OSA, and reduces overall health care costs. Better understanding of the pathogenesis, risk factors, diagnosis, and treatment of OSA has the potential to improve early recognition of OSA and prevention of adverse effects on the individual and society.

Sore throat is a common medical complaint seen by the emergency practitioner, internist, pediatrician, and otolaryngologist. The differential for sore throat is vast. ⋯ By paying particular attention to the associated symptoms and duration of symptoms, common self-limited etiologies like viral pharyngitis and nonstreptococcal tonsillitis can be distinguished from those that require more investigation, such as supraglottitis and tonsillar cancer. A sore throat is most commonly caused by an infectious, inflammatory, or neoplastic etiologic factor.
