Altered gene expression occurs in the brain after global ischemia. We have developed a model to examine the effects of cardiopulmonary bypass and hypothermic circulatory arrest (HCA) on the induction of the immediate-early gene c-fos in the brains of neonatal lambs. We then tested the effects of the noncompetitive N-methyl-D-aspartate antagonist, aptiganel hydrochloride (Cerestat), on c-fos expression and neuronal injury. ⋯ These experiments indicate that the transcriptional processes of immediate-early genes remain intact, whereas translational processes are impaired after prolonged HCA. The inability to synthesize Fos proteins after 120 minutes of HCA was associated with neuronal degeneration. Aptiganel preserved translational processes and caused a significant improvement in the neurologic outcome.

The development of new screening techniques for the early detection of Marfan's syndrome has prompted evaluation of the results of cardiac operations in children with this syndrome. The purpose of this study was to determine the surgical indications, operative results, and need for reoperation in children with Marfan's syndrome. ⋯ We conclude that (1) aortic root dilatation is the most common surgical indication in children with Marfan's syndrome, (2) mitral regurgitation is the second most common indication, (3) aortic dissection is unusual in children with Marfan's syndrome, and (4) careful follow-up is necessary, particularly in younger children, because more than half of all children with Marfan's syndrome require repeated cardiac operations within 10 years.

Bronchopeural fistula after pneumonectomy, with associated empyema, has no standard therapy. The transsternal, transpericardial approach was used in all patients presenting with a large fistula. ⋯ Long-term results of transsternal closure are good, but hospital mortality is high. The present treatment of patients with large postpneumonectomy bronchopleural fistula includes early open thoracostomy, improvement of nutritional status, transsternal closure using resorbable sutures, and closure of the pleural space 3 weeks later.

Biography Historical Article
Cemil Topuzlu Pacha and his arterial suture technique.
Cemil Topuzlu Pacha (1868-1958) is known to be one of the most famous surgeons in Turkey through the early decades of the twentieth century. Being a talented and courageous surgeon, he performed many of the avoided operations of that time. He presented his vascular suture techniques at the International Medical Congress in Moscow in August 1897 and at the annual Congress of the Societe de Chirurgie de Paris in July 1904. ⋯ He also reported the removal of a pen cover from the right main bronchus of a 7-year-old girl through a tracheotomy in 1903. He worked for 3 years with the famous French surgeon Jules Pean and became a preferred surgeon of the Ottoman Imperial family in Istanbul. He was admired for his scientific studies in international congresses and was one of the first Turkish surgeons who became a member of important European surgical associations.

Review Case Reports
Coronary artery bypass grafting in immune thrombocytopenic purpura.
Reports of patients with idiopathic thrombocytopenic purpura undergoing cardiac operations are scarce and no recommendations exist regarding their management. We report 3 patients with idiopathic thrombocytopenic purpura and severe coronary artery disease who underwent uncomplicated coronary bypass grafting. ⋯ Coronary artery bypass grafting can be safely performed in patients with idiopathic thrombocytopenic purpura using conventional conduits after pretreating with immunoglobulin G and avoiding splenectomy.
