Most popular medical Questions
When should myocarditis be suspected?The presenting symptoms of myocarditis can be variable, ranging from subclinical to rapidly progressive CHF. It should be considered in any patient who experiences unexplained heart failure. Clinical signs include tachycardia out of proportion to fever, tachypnea, a quiet precordium, muffled heart tones, gallop rhythm without murmur, and hepatomegaly.
When should steroids be given to a child with myocarditis?
The use of steroids in patients with myocarditis is controversial. Some authorities feel that the use of steroids may inhibit interferon synthesis and increase viral replication. If the inflammatory process is secondary to rheumatic fever, however, then steroids may be indicated.
A child visiting from Mexico presents symptoms including unilateral eye swelling and new-onset acute CHF. What is a likely diagnosis?
Acute myocarditis as a result of Chagas' disease (American trypanosomiasis) is likely. Seen in 25-50% of patients in endemic areas with early Chagas' disease, Romana sign is unilateral, painless, violaceous, palpebral edema often accompanied by conjunctivitis. The swelling occurs near the bite site of the parasitic vector: the reduviid or Triatominae bug. Chagas' disease, a protozoan infection, is the most common cause of acute and chronic myocarditis in Mexico and in Central and South America.
What is Kawasaki disease?
A multisystem disease characterized by a vasculitis of small and medium-sized blood vessels. If untreated, this can lead to coronary artery aneurysms and myocardial infarction.
Is aspirin therapy of benefit for children with Kawasaki disease?
By itself, high-dose aspirin (80-100 mg/kg/day divided into doses taken every 6 hours) is effective for decreasing the degree of fever and discomfort in patients during the acute stages of illness. It is unclear if high-dose aspirin has an additive effect for decreasing the incidence of coronary artery abnormalities when used in conjunction with gamma globulin. Aspirin may be beneficial when administered in low doses after the resolution of fever due to its effects on platelet aggregation and prevention of the thrombotic complications seen in children with Kawasaki disease. Therefore, aspirin in low doses (3-5 mg/kg/day) is advised for about 6-8 weeks. If a follow-up echocardiogram at that time reveals no coronary abnormalities, therapy is usually discontinued. If abnormalities are present, therapy is continued indefinitely.
How valuable are digoxin levels?
Digoxin levels are only useful as a guide to digoxin therapy. Digoxin levels may not be as helpful in infants and younger children because of the presence of endogenous digoxin-like immunoreactive substances, which cross-react with immunoassay antibodies to digoxin. Digoxin levels may be helpful, however, in older children and adolescents (especially in the presence of dysrhythmias).
How long before oral digoxin begins to work?
Oral digoxin reaches peak plasma levels 1-2 hours after administration, but a peak hemodynamic effect is not evident until 6 hours after administration (versus 2-3 hours for intravenous digoxin).
A child with WPW syndrome and SVT is given digoxin, and the attending cardiologist is dismayed. Why?
Digoxin can enhance conduction through a bypass tract while slowing down conduction through the AV node. Ventricular fibrillation has been reported in patients with WPW treated with digoxin. This effect is believed to be due to enhanced conduction down the bypass tract. For this reason, propranolol has replaced digoxin as the drug of choice for the treatment of children with SVT and WPW.
