Further remarks on convergence of decomposition method.

The decomposition method solves a wide class of nonlinear functional equations. This method uses a series solution with rapid convergence. This paper is intended as a useful review and clarification of related issues.

Verapamil induced ventricular hypertrophy in conscious dogs.

Verapamil is used clinically in the treatment of various cardiac diseases including hypertrophic cardiomyopathy. Its long term effects on ventricular mass are not well known. In 11 conscious dogs heart rate, aortic and left ventricular pressures, cardiac output, a methoxamine induced stress ventricular function test and left ventriculography were performed.

Achondrogenesis type I: delineation of further heterogeneity and identification of two distinct subgroups.

Achondrogenesis has traditionally been divided into type I (Parenti-Fraccaro) and type II (Langer-Saldino). We studied the clinical, radiologic, and morphologic features of 17 cases previously diagnosed as achondrogenesis type I to define whether there is even further heterogeneity. On radiographic analysis, two distinct groups of patients were defined based on the presence or absence of rib fractures and ossification of the vertebral pedicles, ischium, and fibula.

Dyssegmental dysplasias: clinical, radiographic, and morphologic evidence of heterogeneity.

The dyssegmental dysplasias are lethal forms of neonatal short-limbed dwarfism in which vertebral segmentation defects and short, thick, bowed long bones are the prominent radiographic features. Clinically, unusual facies, short neck, narrow thorax, cleft palate, and reduced joint mobility are commonly seen. To date, 18 cases of dyssegmental dysplasia have been reported.

Prenatal diagnosis of osteogenesis imperfecta type III.

Ultrasonographic and radiographic evaluation of a fetus at risk for osteogenesis imperfecta (O.I) type III was performed. Real-time ultrasound measurements at 15 weeks gestation were interpreted as normal, but at 20 and 22 weeks of gestation revealed marked shortening of the long bones and deformity of the femurs.
