Pregnancy results in physiologic and anatomic changes that allow the mother to adapt to the greater metabolic requirements of pregnancy. These changes include the enlarging uterus, which results in compression of surrounding structures, and increased hormonal production, which exerts its effects on maternal physiology. Cardiac output increases to maintain higher uterine blood flow, and minute ventilation increases, which results in a chronic respiratory alkalosis. Plasma volume increases, which results in physiologic anemia of pregnancy and may contribute to gestational thrombocytopenia. An understanding of these and other changes that occur in pregnancy is important for the anesthesiologist because they have important implications for management of the parturient undergoing an anesthetic procedure. The goal of this chapter is to highlight some of the most salient features of physiologic changes that occur during pregnancy and to begin to offer some basic anesthetic management strategies. This review contains 6 tables, and 36 references. Key Words: airway changes during labor, cardiovascular changes during pregnancy, gastroesophageal reflux disease, gestational thrombocytopenia, hydronephrosis during pregnancy, left uterine displacement, physiologic anemia, ventilatory mechanics

Acute renal failure (ARF) has been defined as a syndrome in which an abrupt decrease in renal function produces retention of nitrogenous waste products. Translating this abstract description into a clinically useful, accurate, and widely accepted definition has been challenging, in large part because of the focus on serum creatinine concentration, which is easily obtained but has the inherent limitation of poor detection of rapid or subtle, but clinically important, changes in the glomerular filtration rate (GFR). In recent years, therefore, the term acute kidney injury (AKI) has replaced ARF because AKI denotes the entire clinical spectrum from mild increases in serum creatinine to overt renal failure. AKI is defined by the Risk-Injury-Failure-Loss-ESRD (RIFLE) criteria, based on serum creatinine concentration and urine flow rate. The Acute Kidney Injury Network (AKIN) subsequently modified the definition further and divided AKI into three stages. This part of the AKI review specifically discusses special situations: rhabdomyolysis, aristolochic acid nephropathy, acute urate nephropathy, acute phosphate nephropathy, AKI in multiple myeloma, ehytlene glycol poisoning, contrast-induced nephropathy, AKI in sepsis, hepatorenal syndrome, and AKI in pregnancy.

Elder mistreatment affects a considerable proportion of individuals older than 60 to 65 years of age and may include intentional abuse (physical, sexual, emotional, or financial) and neglect. As the proportion of the population that is older than 65 years of age increases, elder mistreatment will become an increasingly common issue. Only a minority of cases of elder abuse are reported; thus, an interview with the patient should be conducted in private if elder mistreatment is suspected. Patient risk factors for elder mistreatment include cognitive or behavioral impairment, poor physical health, and poor social supports. This review examines the approach to the patient, as well as definitive treatment, disposition, and outcomes for victims of elder abuse. The figure shows an algorithm for elder abuse assessment and intervention. Tables list types of elder abuse, factors predisposing to elder mistreatment, indicators of abuse, and the Elder Abuse Suspicion Index. This review contains 1 highly rendered figure, 4 tables, and 42 references.

Patients with coronary artery disease (CAD) present clinically when their disease enters an unstable phase known as an acute coronary syndrome (ACS), in which the cap of a previously stable atheromatous coronary plaque ruptures or erodes, which in turn activates a thrombotic cascade that may lead to coronary artery occlusion, myocardial infarction (MI), cardiogenic shock, and patient death.

So rapidly has the field of health care ethics continued to grow that, when recently “googled,” the term produced 28.2 million hits. The challenge is to address the ethical and social issues in medicine in this very limited article space. It remains an impossible task to present more than a superficial discussion of these complex issues and the complicated cases in which they are to be found. Like good medicine, good ethics cannot be practiced by algorithm. The authors have opted to provide an operational guide to help clinicians sort through the ethical and social quandaries they must face on a daily basis. To that end, the authors have chosen to divide this chapter into the following sections: 1. A brief description of the biopsychosocial nature of ethics and how it differs from personal morality 2. A method for identifying and dealing with ethical issues 3. A discussion of the role of bioethicists and ethics committees 4. The professional fiduciary role of clinicians 5. Listings of some of the common key bioethical and legal terms (online access only) 6. A very brief discussion of the terms cited in the above listings (online access only) This reviews contains 4 tables, 8 references, 1 appendix, and 20 additional readings.

Acne vulgaris is the most common disorder seen in general dermatology practice, accounting for approximately 10% of visits each year. Both sexes and all ethnicities are affected, usually in the late preteenage or early teenage years. Both inflammatory and comedonal lesions of acne vulgaris characteristically involve the face, but truncal involvement is also relatively common. Multiple clinical presentations may be observed, with severity often progressing over time during adolescence. Severe forms of acne vulgaris can be especially disfiguring and debilitating, and are more likely to lead to permanent scarring. Therapeutic options are chosen primarily on the basis of clinical severity, with adjustments in treatment made on the basis of response or disease progression. Rosacea begins in adulthood, usually in the third decade of life or later. The disorder predominantly affects the central face in fair-skinned people, mostly those of northern European ancestry, although individuals of any race may be affected. Rosacea may present as one or more of a variety of clinical phenotypes (subtypes); it is a chronic disorder characterized by periods of exacerbation and remission. Fortunately, rosacea is not associated with scarring, although a subset of patients may develop localized proliferations of sebaceous and fibrous tissue called a phyma. Like acne vulgaris, rosacea may also adversely impact quality of life. Figures in this chapter illustrate acne vulgaris and inflammatory papules. Tables detail laboratory evaluation for women with acne vulgaris and hyperandrogenism, surgical/physical modality options for specific acne lesions and acne scars, major topical therapies for acne vulgaris, and commonly prescribed systemic therapies for acne. This chapter contains 50 references.

Knowledge of the common nonarticular regional rheumatic disorders is important because of their high prevalence in primary care practice, the dependence on clinical findings for diagnosis, and the high cost that can result from unnecessary laboratory evaluations. The ability to recognize important patterns of pain and associated physical signs is essential to making a correct diagnosis; in most cases, radiographic and laboratory studies are not needed. This review covers the common causes of pain in the neck, back, shoulder, chest wall, elbow, hand and wrist, hip girdle, knee and lower leg, and ankle and foot.

Recent research has generated an enormous fund of knowledge about the neurobiology of sleep and wakefulness. Sleeping and waking brain circuits can now be studied by sophisticated neuroimaging techniques that map different areas of the brain during different sleep states and stages. Although the exact biologic functions of sleep are not known, sleep is essential, and sleep deprivation leads to impaired attention and decreased performance. Sleep is also believed to have restorative, conservative, adaptive, thermoregulatory, and consolidative functions. This review discusses the physiology of sleep, including its two independent states, rapid eye movement (REM) and non–rapid eye movement (NREM) sleep, as well as functional neuroanatomy, physiologic changes during sleep, and circadian rhythms. The classification and diagnosis of sleep disorders are discussed generally. The diagnosis and treatment of the following disorders are described: obstructive sleep apnea syndrome, narcolepsy-cataplexy sydrome, idiopathic hypersomnia, restless legs syndrome (RLS) and periodic limb movements in sleep, circadian rhythm sleep disorders, insomnias, nocturnal frontal lobe epilepsy, and parasomnias. Sleep-related movement disorders and the relationship between sleep and psychiatric disorders are also discussed. Tables describe behavioral and physiologic characteristics of states of awareness, the international classification of sleep disorders, common sleep complaints, comorbid insomnia disorders, causes of excessive daytime somnolence, laboratory tests to assess sleep disorders, essential diagnostic criteria for RLS and Willis-Ekbom disease, and drug therapy for insomnia. Figures include polysomnographic recording showing wakefulness in an adult; stage 1, 2, and 3 NREM sleep in an adult; REM sleep in an adult; a patient with sleep apnea syndrome; a patient with Cheyne-Stokes breathing; a patient with RLS; and a patient with dream-enacting behavior; schematic sagittal section of the brainstem of the cat; schematic diagram of the McCarley-Hobson model of REM sleep mechanism; the Lu-Saper “flip-flop” model; the Luppi model to explain REM sleep mechanism; and a wrist actigraph from a man with bipolar disorder.

There has been a marked increase in the number and complexity of airway procedures performed both in the operating room and procedural areas. The anesthesiologist is challenged with establishing a patent shared airway and maintaining adequate gas exchange in patients with compromised airways and/or respiratory function. This review presents a general approach to the patient presenting for an airway procedure and highlights the commonly occurring complications. Airway fire, bleeding, and airway disruption or obstruction may occur. Some of the newer interventional bronchoscopic procedures are introduced, with emphasis on anesthetic implications. A more detailed discussion surrounds the anesthetic management of central airway obstruction and airway stenting. This review contains 8 figures, 5 tables, 30 references. Key Words: anesthesia for flexible bronchoscopy, anesthesia for rigid bronchoscopy, airway stenting, bronchoscopy, central airway obstruction, interventional pulmonology, total intravenous anesthesia, ventilation
