Follow-up evaluation. •• reevaluate patient if symptoms persist beyond 5 days or worsen at any time. •• if recurrent infections or chronic sinusitis develop, refer to a specialist. Outcome evaluation antibiotics relieve symptoms of streptococcal pharyngitis within 3 to 5 days, and patients can return to work or school if improved after the first 24 hours of therapy. Lack of improvement or worsening after 72 hours of therapy requires reevaluation. Follow-up throat cultures are not recommended unless symptoms persist or recur. Recurrent symptoms following an appropriate treatment course should prompt reevaluation for possible retreatment.

Pathologic murmurs tend to appear at characteristic ages. Semilunar valve stenosis (systolic ejection murmurs) and atrioventricular valvular insufficiency (systolic regurgitant murmurs) tend to be noted very shortly after birth, on the first day of life.

This may be quite valuable to the team of physicians caring for mother and baby, guiding plans for prenatal care, site and timing of delivery, as well as immediate perinatal care of the infant. The recommended timing for fetal echocardiography is 18 to 20 weeks' gestation, although reasonable images can be obtained as early as 16 weeks, and transvaginal ultrasonography may be used for diagnostic purposes in fetuses in the first trimester. Indications for fetal echocardiography are summarized in table 41.4.
