Duplications of the alimentary tract are unusual congenital anomalies that frequently present a diagnostic as well as therapeutic challenge to the surgeon. Because these lesions occur so infrequently, they are often not suspected until encountered intraoperatively. Due to the complicated anatomy and common blood supply shared between the duplication and(More)
One hundred eighty-eight consecutive children with serious blunt abdominal or multisystem trauma were evaluated between August 1981 and July 1985. Of the 188 patients, 53 (28%) were found to have hepatic parenchymal injuries and are the basis of this report. Four of the 53 (8%) underwent emergency laparotomy for exsanguinating hemorrhage; two patients died,(More)
Since ulcerative colitis is a mucosal disease, it would appear possible to remove the diseased rectal mucosa and preserve all anorectal musculature. When performed in conjunction with total colectomy, the terminal ileum could then be placed inside the retained muscular wall of the rectum and anastomosed to the anus. This would remove all of the disease and(More)
Atherosclerosis involves angiogenesis and inflammation with the ability of endothelial cells and monocytes to respond to chemokines. We addressed here by in vitro and in vivo approaches, the role of the chemokine Regulated on Activation, Normal T Cell Expressed and Secreted (RANTES)/CCL5 on angiogenesis through its receptors CCR1, CCR5, syndecan-1 (SDC-1),(More)
Melatonin, a neurohormone secreted by the pineal gland, can stimulate three subtypes of receptors, namely: mt(1), MT(2) and MT(3). We examined the ability of melatonin and the selective MT(3) receptor agonist, 5-methoxycarbonylamino-N-acetyltryptamine (5-MCA-NAT), to modify intraocular pressure in rabbits. Both compounds significantly reduced intraocular(More)
To investigate the prevalence of myocardial contusion associated with blunt chest trauma in the pediatric age group, all patients admitted to our institution during a 6-month period with blunt thoracic trauma severe enough to produce a pulmonary contusion or rib fracture were prospectively evaluated. Cardiac evaluation was undertaken, including a(More)
Conventional 85% pancreatectomy with splenectomy performed for management of hypoglycemia of neonatal nesidioblastosis has been followed by a dismal prognosis characterized by post-splenectomy sepsis, recurrent hypoglycemia, permanent brain damage, and a high mortality. For our last eight infants we have found it possible to remove at least 95% of the(More)
Thirteen patients with total colonic aganglionosis are reported. Nine were treated with an operation to preserve and utilize the descending colon. Because of the encouraging results with this group, the operation for the four most recent infants consisted of a side-to-side anastomosis of the entire aganglionic colon to the ganglionated small bowel.
