Detection of small pulmonary nodules has markedly increased as computed tomography (CT) technology has advanced and interpretation evolved from viewing small CT images on film to magnified images on large, high-resolution computer monitors. Despite these advances, determining the etiology of a lung nodule short of major surgery remains problematic. Initial nodule size is a major criterion in evaluating the risk for malignancy, and the majority of CT detected nodules are <10 mm in diameter. ⋯ Nodule-growth assessment based on 2-dimensional approaches is limited; therefore, software has been developed for the 3-dimensional assessment of growth. Different approaches for such growth assessment have been developed, either using automated computer segmentation techniques or hybrid methods that allow the radiologist to adjust such segmentation. There are, however, inherent reasons for variability in such measurements that need to be carefully considered, and this, together with continued technologic advances and integration of the relevant clinical information, will allow for individualization of the algorithms for the workup of small pulmonary nodules.

Anaphylaxis is a life-threatening allergic condition. The 3 most common triggers for anaphylaxis are food, medications, and insects. All of these triggers are the sources of considerable morbidity and mortality, but of the 3, only insect allergy is treatable through means other than trigger avoidance. ⋯ The proper and primary means of treating acute anaphylaxis is immediate epinephrine-and studies suggest that it is underutilized in the acute setting. However, it is venom immunotherapy, a disease-modifying therapy, that provides the affected individual with the most effective protection against future sting reactions. Long-term management of insect allergy and anaphylaxis includes appropriate referral to an allergist familiar with insect allergy and, if indicated, venom immunotherapy.

Atopic dermatitis, commonly known as eczema, is a common chronic, relapsing skin disease characterized by pruritus, disrupted epidermal barrier function, and immunoglobulin E-mediated sensitization to food and environmental allergens. Atopic dermatitis is a complex disease that arises from interactions between genes and the environment. Loci on several chromosomes have been identified, including a family of epithelium-related genes called the epidermal differentiation complex on chromosome 1q21. ⋯ Conventional therapy includes avoidance of irritants and potential allergens, as well as continued hydration of the skin with thick emollients. Topical corticosteroids and topical immunomodulators are often used primarily. Other therapies including phototherapy, antimicrobials, antihistamines, and systemic immunosuppressives are also options in certain situations.

Palliative care is a medical specialty that aims to improve the quality of life for patients with chronic and advanced serious illness and their families. It is appropriate throughout all stages of the trajectory of illness, which distinguishes it from hospice care. Hospice care is limited to patients with terminal prognoses. ⋯ Palliative care has been associated with improved outcomes for patients and families and has experienced a rapid expansion in available services. Despite this, palliative care consultation continues to be underutilized. As the number of patients living with complex and serious illness burden continues to increase, palliative care specialists will play an important role in providing timely access to critical supportive services and the provision of high-quality care.

Delirium is a common neuropsychiatric syndrome in the elderly that can occur in several different settings caused by several different processes. It is common and causes increased morbidity and mortality to those affected. ⋯ Diagnosis of delirium, specifically with the use of objective instruments, is discussed, as is the evidence for pharmacological and nonpharmacological treatment strategies. Discussion of the neurobiology and genetic markers for delirium may elucidate further areas for future research.
