Clin Exp Pediatr. 2000;43(8):1127-1131.   Published online August 15, 2000
Agenesis of corpus callosum occurs sporadically and may be transmitted as sex-linked, or autosomal-dominant or recessive traits. It has been associated with different syndromes. Clinical pictures vary from severe intellectual and neurologic abnormalities to asymptomatic and normaly intelligent cases. Agenesis of corpus callosum may occur alone, but it is more frequently associated with a high incidence of other anomalies. We...

Clin Exp Pediatr. 2000;43(8):1090-1097.   Published online August 15, 2000
Purpose : Ceftriaxone, a parenteral third-generation cephalosporine, is widely used in the treatment of various bacterial infections. It possesses high calcium-binding affinity, forming complexes with calcium in bile salts to develop precipitate that mimics gallstone on ultrasonography. Biliary pseudolithiasis resolves completely with cessation of therapy, but several symptomatic patients have undergone cholesystectomy. We prospectively evaluated the incidence, risk factors and...
