A fetus with an immature umbilical cord teratoma associated with exomphalos: case report and review of the literature.

Objective: To describe the antenatal and pathological features of an immature umbilical cord teratoma associated with exomphalos, and to review the literature on this subject.

Case Presentation: An abdominal wall defect, suspected to be an exomphalos, was identified during routine ultrasound examination performed at 13 weeks of gestation. The pregnancy was terminated.

Low doses of ionizing radiation activate endothelial cells and induce angiogenesis in peritumoral tissues.

Purpose: During radiotherapy the peritumoral tissues are daily exposed to subtherapeutic doses of ionizing radiation. Herein, the biological and molecular effects of doses lower than 0.8 Gy per fraction (LDIR), previously described as angiogenesis inducers, were assessed in human peritumoral tissues.

Signet Ring Cell Carcinoma, Ileal Crohn Disease or Both? - A Case of Diagnostic Challenge.

Signet ring cell carcinoma is a rare form of adenocarcinoma that predominantly affects the stomach. Signet ring cell carcinoma originated from the ileum is extremely rare and the prognosis is poor. We present a case of small bowel obstruction with features suggesting Crohn disease of the ileum.

A case of post-radiotherapy gastritis: radiation does not explain everything.

Hemorrhagic gastritis is a possible late toxicity outcome after radical radiotherapy but it is nowadays a very rare condition and most likely depends on other clinical factors. We report the case of a 77-year-old woman with a symptomatic solitary extramedullary intra-abdominal plasmacytoma and multiple gastric comorbidities, treated with external beam radiotherapy. Despite the good response to radiotherapy, the patient experienced multiple gastric bleeding a few months later, with the need of multiple treatments for its control.

Lipomatous hypertrophy of the interatrial septum: report of two cases where histological examination and surgical intervention were unavoidable.

Lipomatous hypertrophy of the interatrial septum (LHIS) is an increasingly recognized heart condition characterized by fatty deposits in the interatrial septum with sparing of the fossa ovalis. Its distinctive characteristic features by imaging techniques, benign nature, and the fact that most patients remain asymptomatic, has limited the need for histological confirmation and operative intervention in most cases. In this report, we describe two cases of LHIS where cardiac surgical intervention was indispensable: in the first patient, due to the presence of an additional left atrial tumour found out as mixoma and in the second, to relief a superior vena cava obstruction together with bypass grafts for severe coronary artery disease.

C4d-the witness of humoral rejection.

Objective: Acute antibody-mediated (humoral) rejection is a major cause of morbidity, graft loss, and mortality among heart transplant patients. Herein we have presented our experience using C4d to characterize humoral rejection.

Materials And Methods: All nonformalin-fixed cardiac graft biopsies (protocol or emergency) received between May 2007 and May 2008 were examined by immunofluorescence for C4d.

Pediatric minor head trauma: indications for computed tomographic scanning revisited.

Background: Although the use of computed tomographic (CT) scanning in severe head trauma is an accepted practice, the indications for its use in minor injury remain ill defined and subjective. We sought to define the incidence and identify risk factors for intracranial injury (ICI) after minor head trauma in children who did not have suspicious neurologic symptoms in the field or on presentation.

Methods: From January 1, 1992, until April 1, 2000, 569 blunt trauma patients (age < 16 years) with a Glasgow Coma Scale score of 14 or 15 triaged by American College of Surgeons Pediatric Mechanism Criteria at a Level I trauma center received head CT scan.
