Seizures are among the most common neurologic conditionsencountered in the primary care setting. However, they havereceived scant attention in standard textbooks and in themedical literature generally-perhaps because the topic cutsacross so many specialties. Here, an international team ofexperts fills this void with a comprehensive discussion of thecauses and management of seizures associated with a widevariety of medical problems-including organ failure,organ transplantation, electrolyte imbalance, endocrine disorders,cardiorespiratory disorders, cancer, fever and systemicinfection, medication, alcohol, illicit drug use, andenvironmental toxins. Chapters cover the various types ofseizures and their pathophysiology, how to distinguishseizure from syncope, seizures in the ICU, and the use ofanticonvulsants.

Abstract: Although cystic fibrosis (CF) is typically diagnosed during infancy or childhood, it may escape detection until adulthood. Diagnostic accuracy can be sharpened by maintaining a high index of suspicion for CF in an adult who is pancreatic-sufficient but has unexplained recurrent respiratory infections, bronchiectasis, or nutritional deficiencies. The workup begins with the quantitative pilocarpine iontophoresis sweat test. If necessary, additional tests include mutation analysis, full-gene sequencing of CF transmembrane conductance regulator protein, and measurement of nasal transepithelial potential difference. Multidisciplinary care is essential and includes nutritional support, chest physiotherapy, exercise, appropriate antibiotics, and other pulmonary interventions. Dornase alpha, inhaled tobramycin, and azithromycin have been associated with improved outcomes and are considered to be the standard of care for patients with moderate lung involvement.
