The ductus arteriosus is an arterial shunt between the aorta and a pulmonary artery, physiological during fetal development, this period it shunts away part of blood circulation that would go to lungs, which at moment are still afunctional. After birth, there closure duct, its non-occlusion called persistent (PDA), treated surgically. We report clinical case female canine German dwarf spitz bre...

Ecological explanations have been put forward to account for the precocious or delayed development of patency in ducts leading to the vomeronasal organ (VNO) in certain mammals. Perinatal function may be related, in part, to the patency or fusion of the vomeronasal and nasopalatine (NPD) ducts. However, few studies have focused on NPD development in primates, which generally have a prolonged pe...

AIMS This paper describes a simple technique of axillary and breast massage which improves the successful identification of blue sentinel nodes using patent blue dye alone. METHODS Patent blue dye was injected in the subdermal part of the retroaroelar area in 167 patients having surgical treatment for invasive breast cancer. Three stage axillary lymphatic massage was performed prior to making...

Ibuprofen is a well-known agent used to treat patent ductus arteriosus in preterm neonates in the first days of life. In the current case report we illustrate the potential use of ibuprofen in two preterm neonates 60 and 88 days after birth, respectively. To our knowledge, this is the first report on the effects of ibuprofen on patent ductus arteriosus in preterm newborns after months of life. ...

Diagnosis of patent ductus arteriosus is rare in adulthood. Closure of ductus is difficult when diagnosed at an adult age due to the development of pulmonary hypertension and pulmonary arterial disease that generally occurs. Closure of the ductus might be contraindicated, as it may lead to deterioration of the pulmonary arterial perfusion or to a pulmonary hypertensive crisis. In addition, anot...

The remarkable success that has attended surgical ligation of the patent ductus arteriosus has aroused a new interest in a unique structure and has been the means of revealing striking gaps in our knowledge -of a comparatively common form of congenital heart disease. Unexpectedly, ligation of the infected ductus has shed a new light on the most serious of all forms of heart disease-bacterial en...

RATIONAL Patent urachus (PU) is due to an incomplete obliteration of the urachus, whereas patent omphalomesenteric duct (POMD) is due to an incomplete obliteration of the vitelline duct. These anomalies are very rarely associated with one another. We describe a case of a newborn with a PU associated with a POMD, who was diagnosed by an abdominal ultrasound (US) and laparoscopy, and managed with...

The influence of bile acids on adenosine 3',5'-phosphate-induced intestinal secretion was studied in mice. Bile flow was stopped by ligation of the common bile duct, and secretion was induced in ligated loops of the small intestine. The decrease of bile led to inhibition of hypersecretion after challenge with heat-labile enterotoxins from Vibrio cholerae and Escherichia coli, as well as with pr...
