INTRODUCTION We aimed to critically evaluate elective preterm delivery and immediate abdominal wall closure and other techniques for the management of gastroschisis, hypothesizing that the advantages of an elective preterm delivery outweigh possible complications related to prematurity at birth. PATIENTS AND METHODS 13 gastroschisis patients were enrolled(More)
Hirschsprung disease (HSCR) is transmitted in a complex pattern of inheritance and is mostly associated with variants in the RET proto-oncogene. However, RET mutations are only identified in 15-20% of sporadic HSCR cases and solely in 50% of the familial cases. Since genomic rearrangements in particularly sensitive areas of the RET proto-oncogene and/or(More)
The addition of chondroitin sulphate (CS) to bone cements with calcium phosphate has lead to an enhancement of bone remodeling and an increase in new bone formation in small animals. The goal of this study was to verify the effect of CS in bone cements in a large animal model simulating a clinically relevant situation of a segmental cortical defect of a(More)
Transforaminal lumbar interbody fusion (TLIF) is a relatively new technique of lumbar arthrodesis via posterior transforaminal approach to the disc, indicated mainly in cases of degenerative disc disease, low grade spondylolisthesis and reoperation for disc herniation, specially when there is indication for interbody fusion and posterior decompression. The(More)

Disorders of sex development (DSD) affect the development of chromosomal, gonadal and/or anatomical sex. We analyzed a patient with ambiguous genitalia aiming to correlate the genetic findings with the phenotype. Blood and tissue samples from a male patient with penoscrotal hypospadias were analyzed by immunohistochemistry, karyotyping and FISH. DNA was(More)
Dr. Nicandro Figueiredo – Avenida das Flores 941 / 1 floor / Instituto Neurológico e da Coluna Vertebral 78043-172 Cuiaba MT Brasil. E-mail: Abnormalities of the craniovertebral junction are of great interest not only to anatomists but also to clinicians, because many of these malformations can produce neurological symptoms and death.(More)
Central congenital hypoventilation syndrome (CCHS) is an autonomous control disease producing hypoventilation, high PaCO(2), and low PaO(2) during quiet sleep. The main gene variants detected in CCHS are mutations in the PHOX2b gene in up to 97% of isolated cases. However, CCHS is sometimes associated with autonomic diseases such as Hirschsprung disease(More)
BACKGROUND Infantile hypertrophic pyloric stenosis (IHPS) is a common childhood pathology affecting 1 to 5:1000 newborns, with a genetic background suggested by familial occurrence. Neuronal nitric oxide synthase (NOS1) is a candidate gene owing to its role in the relaxation of smooth musculature and the association of the -84g>a variant of NOS1 with IHPS.(More)
