A febrile seizure is a seizure occurring in a child six months to five years of age that is accompanied by a fever (100.4°F or greater) without central nervous system infection. Febrile seizures are ...classified as simple or complex. A complex seizure lasts 15 minutes or more, is associated with focal neurologic findings, or recurs within 24 hours. The cause of febrile seizures is likely multifactorial. Viral illnesses, certain vaccinations, and genetic predisposition are common risk factors that may affect a vulnerable, developing nervous system under the stress of a fever. Children who have a simple febrile seizure and are well-appearing do not require routine diagnostic testing (laboratory tests, neuroimaging, or electroencephalography), except as indicated to discern the cause of the fever. For children with complex seizures, the neurologic examination should guide further evaluation. For seizures lasting more than five minutes, a benzodiazepine should be administered. Febrile seizures are not associated with increased long-term mortality or negative effects on future academic progress, intellect, or behavior. Children with febrile seizures are more likely to have recurrent febrile seizures. However, given the benign nature of febrile seizures, the routine use of antiepileptics is not indicated because of adverse effects of these medications. The use of antipyretics does not decrease the risk of febrile seizures, although rectal acetaminophen reduced the risk of short-term recurrence following a febrile seizure. Parents should be educated on the excellent prognosis of children with febrile seizures and provided with practical guidance on home management of seizures.
Bronchiolitis is a common lower respiratory tract infection in infants and young children, and respiratory syncytial virus (RSV) is the most common cause of this infection. RSV is transmitted through ...contact with respiratory droplets either directly from an infected person or self-inoculation by contaminated secretions on surfaces. Patients with RSV bronchiolitis usually present with two to four days of upper respiratory tract symptoms such as fever, rhinorrhea, and congestion, followed by lower respiratory tract symptoms such as increasing cough, wheezing, and increased respiratory effort. In 2014, the American Academy of Pediatrics updated its clinical practice guideline for diagnosis and management of RSV bronchiolitis to minimize unnecessary diagnostic testing and interventions. Bronchiolitis remains a clinical diagnosis, and diagnostic testing is not routinely recommended. Treatment of RSV infection is mainly supportive, and modalities such as bronchodilators, epinephrine, corticosteroids, hypertonic saline, and antibiotics are generally not useful. Evidence supports using supplemental oxygen to maintain adequate oxygen saturation; however, continuous pulse oximetry is no longer required. The other mainstay of therapy is intravenous or nasogastric administration of fluids for infants who cannot maintain their hydration status with oral fluid intake. Educating parents on reducing the risk of infection is one of the most important things a physician can do to help prevent RSV infection, especially early in life. Children at risk of severe lower respiratory tract infection should receive immunoprophylaxis with palivizumab, a humanized monoclonal antibody, in up to five monthly doses. Prophylaxis guidelines are restricted to infants born before 29 weeks' gestation, infants with chronic lung disease of prematurity, and infants and children with hemodynamically significant heart disease.
Acute kidney injury is a clinical syndrome characterized by a rapid decline in glomerular filtration rate and resultant accumulation of metabolic waste products. Acute kidney injury is associated ...with an increased risk of mortality, cardiovascular events, and progression to chronic kidney disease. Severity of acute kidney injury is classified according to urine output and elevations in creatinine level. Etiologies of acute kidney injury are categorized as prerenal, intrinsic renal, and postrenal. Accurate diagnosis of the underlying cause is key to successful management and includes a focused history and physical examination, serum and urine electrolyte measurements, and renal ultrasonography when risk factors for a postrenal cause are present (e.g., older male with prostatic hypertrophy). General management principles for acute kidney injury include determination of volume status, fluid resuscitation with isotonic crystalloid, treatment of volume overload with diuretics, discontinuation of nephrotoxic medications, and adjustment of prescribed drugs according to renal function. Additional supportive care measures may include optimizing nutritional status and glycemic control. Pharmacist-led quality-improvement programs reduce nephrotoxic exposures and rates of acute kidney injury in the hospital setting. Acute kidney injury care bundles are associated with improved in-hospital mortality rates and reduced risk of progression. Nephrology consultation should be considered when there is inadequate response to supportive treatment and for acute kidney injury without a clear cause, stage 3 or higher acute kidney injury, preexisting stage 4 or higher chronic kidney disease, renal replacement therapy, and other situations requiring subspecialist expertise.
The authors of this Cochrane review evaluated studies of walking compared with no physical activity to lower blood pressure.1 This review included 73 randomized controlled trials and 5,763 ...participants. The primary outcome was change in systolic blood pressure; secondary outcomes included changes in diastolic blood pressure and heart rate. The findings of this review suggest that a walking regimen—three to five times a week at a moderate intensity for 20 to 40 minutes per session, with at least 150 total minutes per week for approximately three months—can lower systolic blood pressure, diastolic blood pressure, and heart rate in adult men and women with or without hypertension.
In the United States, pneumonia is the most common cause of hospitalization in children. Even in hospitalized children, community-acquired pneumonia is most likely of viral etiology, with respiratory ...syncytial virus being the most common pathogen, especially in children younger than two years. Typical presenting signs and symptoms include tachypnea, cough, fever, and anorexia. Findings most strongly associated with an infiltrate on chest radiography in children with clinically suspected pneumonia are grunting, history of fever, retractions, crackles, tachypnea, and the overall clinical impression. Chest radiography should be ordered if the diagnosis is uncertain, if patients have hypoxemia or significant respiratory distress, or if patients fail to show clinical improvement within 48 to 72 hours after initiation of antibiotic therapy. Outpatient management of community-acquired pneumonia is appropriate in patients without respiratory distress who can tolerate oral antibiotics. Amoxicillin is the first-line antibiotic with coverage for Streptococcus pneumoniae for school-aged children, and treatment should not exceed seven days. Patients requiring hospitalization and empiric parenteral therapy should be transitioned to oral antibiotics once they are clinically improving and able to tolerate oral intake. Childhood and maternal immunizations against S. pneumoniae, Haemophilus influenzae type b, Bordetella pertussis, and influenza virus are the key to prevention.
Four dietary plans can reduce A1C levels but may differ in long-term outcomes. Intensive lifestyle interventions may even make remission possible.

More than 70% of adults treated for primary hypertension will eventually require at least two antihypertensive agents, either initially as combination therapy or as add-on therapy if monotherapy and ...lifestyle modifications do not achieve adequate blood pressure control. Four main classes of medications are used in combination therapy for the treatment of hypertension: thiazide diuretics, calcium channel blockers, angiotensin-converting enzyme inhibitors (ACEIs), and angiotensin receptor blockers (ARBs). ACEIs and ARBs should not be used simultaneously. In black patients, at least one agent should be a thiazide diuretic or a calcium channel blocker. Patients with heart failure with reduced ejection fraction should be treated initially with a beta blocker and an ACEI or ARB (or an angiotensin receptor-neprilysin inhibitor), followed by add-on therapy with a mineralocorticoid receptor antagonist and a diuretic based on volume status. Treatment for patients with chronic kidney disease and proteinuria should include an ACEI or ARB plus a thiazide diuretic or a calcium channel blocker. Patients with diabetes mellitus should be treated similarly to those without diabetes unless proteinuria is present, in which case combination therapy should include an ACEI or ARB.
Patient age, baseline cardiovascular disease risk, bleeding risk, and personal preference regarding aspirin use are key to decision making. A clinical decision tool can help.
