62 - Kussmaul’s sign is jugular vein distension during inspiration (reversal of normal pattern of decreasing jugular venous pressure during inspiration); classically seen in constrictive pericarditis because of normal increase in venous return with increased abdominal pressure from diaphragmatic contraction leading to increase in right atrial pressure from non-complaint right ventricle - though most common contemporary cause is severe right-sided heart failure (JAMA 1996: 275:632); generally negative in cardiac tamponade.
63 - Nijmegen breakage syndrome is primary immunodeficiency autosomal recessive disorder that presents as microcephaly - a distinctive “bird-like” facies - growth retardation - recurrent pulmonary infections - chromosomal instability - radiation hypersensitivity - and increased incidence of malignancies - especially lymphomas from mutation in nibrin protein - a protein involved in DNA repair; cellular defect similar to ataxia-telangiectasia.

68 - Möbius syndrome is congenital facial paralysis with or without limb defects associated with maternal misoprostol use.
69 - Landolfi’s sign is in aortic regurgitation - systolic contraction and diastolic dilation of the pupil.
70 - Rasmussen’s encephalitis is progressive childhood disease characterized by severe epilepsy - hemiplegia - dementia - and inflammation of the brain potentially from autoantibodies to GluR3 antigen.
