Discussion adolescent tibia vara (Blount’s disease), results from disordered growth of proximal medial physis & metaphysis; localized varus deformity, often accompanied by medial tibial torsion; caused by osteochondrosis resulting from mechanical stress converting physiologic bowlegs to tibia vara; risk factors: common in blacks & obese children; adolescent Blount’s is less severe and predominately unilateral; Treatment … Read more
– indicated for PSVT; – if arrhythmias are not due to reentry involving the AV node or sinus node (eg, atrial flutter, atrial fibrillation, atrial or ventricular tachycardias), adenosine will not terminate the arrhythmia but may produce transient AV or ventriculoatrial block that may clarify dx; – Dose: – half-life of adenosine is less than … Read more
