We encountered six female infants with a specific pattern of developmental abnormalities of the urogenital and lower intestinal tracts. The anomalies included ambiguous genitalia, lack of perineal openings, and müllerian and urinary tract anomalies. Each patient had normal female chromosomes and normal adrenal gland function. We believe that this(More)
We present the findings of 13 additional cases of the urorectal septum malformation (URSM) sequence, and review the literature. The URSM sequence consists of ambiguous genitalia concurrent with absence of perineal and anal openings. The sex ratio of the 13 new cases was 7 males to 6 females and from the literature 21 males and 28 females. In addition, 11 of(More)
The Antley-Bixler syndrome (ABS) is characterized by craniosynostosis, radiohumeral synostosis, and femoral bowing. Other findings include a trapezoid-shaped head, deformed ears, severe midface hypoplasia, choanal atresia or stenosis, and long bone fractures. Most ABS cases have died in the first months of life from respiratory complications. The poor(More)
Wiedemann-Beckwith syndrome (WBS) has attracted a great deal of attention because of its genetic complexity. Individuals with WBS can be identified objectively by anthropometric analysis. Craniofacial anthropometry in conjunction with multivariate statistical analysis can be used to define patterns of variability that appear to relate to specific modes of(More)
We report our preliminary observations in six fetal lambs that were surgically manipulated in utero to impede the blood flow of the carotid arteries and their branches, including the laryngeal artery, the anastomotic branch between the vertebral artery and the occipital artery, the auricularis and the transverse facial arteries. Between 115 and 117 days of(More)
BACKGROUND Atrial fibrillation (AF) is a common complication after coronary artery bypass grafting (CABG). Since its prevention with prophylactic drug therapy has limited success, alternative approaches are desirable. This study examined the efficacy of atrial or biatrial pacing, compared with no pacing, on the incidence of AF after isolated CABG. METHODS(More)
The prenatal diagnosis of bone dysplasias presents difficult challenges for the clinician involved in monitoring pregnancies. Such diagnoses highlight delicate ethical issues and may require difficult decision-making when the differential diagnosis includes a lethal bone dysplasia. Despite the rapid technological advances in ultrasonography, the ability to(More)
We present here a set of 24 standardized linear measurements that describe the growth of different craniofacial structures in the normal fetus from 16 to 36 weeks of gestation. These measurements were taken from 89 pregnant women, who had from 1 to 3 ultrasonographic evaluations during the pregnancy (16, 26, and 36 weeks of gestation). All the values(More)
The study of fetal growth and development by ultrasound has been greatly facilitated in the past few years by the availability of anthropometric standards for the fetal body. Thus, the obstetrician is able to discern between normal and grossly abnormal, and even to quantitate certain fine fetal structures such as the face. This paper presents results(More)
