(17) A report is given on a small-for-date male infant showing the following symptoms: bilateral aplasia of humerus, radius, and ulna, shortened femora, bilateral cleft lip and cleft palate, stigmata of dysmorphism, and notably; simple helix formation of the ear, simian crease, clinodactylia, bilateral clubfoot deformity, hypospadia, thrombocytopenia, micrognathia, and contractures in the knee joints.
(18) Ouabain produced only contracture without positive inotropy.
(19) Fetal malformations in this group were limited from modest to moderate contractures of the front limbs, which resolved by 8-10 weeks post partum.
(20) In vitro contracture tests used currently for malignant hyperthermia (MH) do not possess absolute specificity.

(5) In patients with spastic paraplegia presenting with recurrent dislocation of the hip, operative treatment combining a soft tissue repair and a bone block to augment the acetabulum is recommended.
(6) These initial reflex responses were exaggerated in the spastics as compared with the normals.
(7) The authors elaborated differentiated complexes of rehabilitative treatment for patients with spastic hemiparesis, normal or decreased tone, as well as for patients with transient disorders of cerebral circulation in conditions of a cardiological sanatorium.
