Article Synopsis
  • Erythrocyte deformability is essential for tissue perfusion, and this study investigates how Thymoquinone affects this property in rats with lower extremity ischemia-reperfusion injury.
  • Researchers divided Wistar rats into five groups, including a control and various Thymoquinone treatment groups, to examine its effects on erythrocyte deformability and other markers post-injury.
  • Results showed that Thymoquinone significantly improved erythrocyte deformability and morphology while increasing the activity of endothelial nitric oxide synthase compared to the untreated ischemia-reperfusion group.*

N-acetylcysteine (NAC) is an antioxidant which works as a free radical scavenger and antiapoptotic agent. N-acetylcysteine-amide (NACA) is a modified form of NAC containing an amide group instead of a carboxyl group of NAC. Our study aims to investigate the effectiveness of these two substances on erythrocyte deformability and oxidative stress in muscle tissue.

Pediatric supracondylar fractures of the humerus are generally associated with neurovascular complications due to the deformity and sharp nature of bone fragments. When treated inadequately, these injuries may result in catastrophic complications, such as Volkmann's contracture and amputation. To our knowledge, late onset brachial arterial thrombosis and total temporary peripheral neuropathy after surgery of pediatric supracondylar fracture in the setting of normal preoperative vascular examination has not been reported yet.

Background: We aimed to highlight the use of a minimally invasive approach in uncomplicated congenital heart surgery.

Patients And Methods: We investigated retrospectively 32 children below 10 years of age who underwent elective closure of ostium secundum type (n = 27), sinus venosus type (n = 4) and ostium primum type (n = 1) atrial septal defects through a limited skin incision and partial lower sternotomy between August 2001 and December 2008. All patients had cannulation through the same incision for cardiopulmonary bypass.

Background: The aim of this study was to determine a method to decrease the use of homologous blood during openheart surgery using a simple blood-conservation protocol. We removed autologous blood from the patient before bypass and used isovolumetric substitution. We present the results of this protocol on morbidity and mortality of surgery patients from two distinct time periods.

The pathogenesis of in situ thrombosis in cancer patients is not well known. Possible factors include endothelial damage, decreasing levels of anticoagulant factors and increasing levels of pro-coagulants. In the literature, the incidence of arterial thrombosis in cancer patients is reported to be 3.

We present here the fourth patient in the literature, over the age of 50 years old, with an abnormal right coronary artery arising from the pulmonary artery, who was successfully treated with surgery. Pre-operative computerised tomography (CT) angiography revealed an abnormal right coronary artery arising from the pulmonary artery. The right coronary artery was surgically transposed from the pulmonary artery to the ascending aorta with the aid of cardiopulmonary bypass.

Although all beta blockers appear to be effective in the prevention of postoperative atrial fibrillation (AF) following coronary artery bypass surgery (CABG), carvedilol was found to be much more effective than metoprolol in this respect as the current study clearly delineated. We believe that the ongoing COMPACT trial will answer the question of whether or not carvedilol is more superior than metoprolol to prevent postoperative AF in patients undergoing CABG.

The reinsertion rate of intraaortic balloon pumps (IABP) has not been clearly reported. We evaluated the use of left-ventricular ejection fraction (LVEF), fractional shortening (FS), and cardiac index (CI) values to asses cardiac performance as weaning criteria for IABP in a prospective study performed in 100 patients who required IABP. Patients were randomly divided into 2 groups of 50 patients.

Pneumopericardium is a very rare condition, less common than isolated pneumothorax or pneumomediastinum. Since it can occasionally cause pericardial tamponade, prompt recognition and treatment of this condition is lifesaving. Up to now only one case of isolated pneumopericardium after endomyocardial biopsy has been reported in a two-month boy with a dilated cardiomyopathy of unknown origin.

Background: There is little information available about any link between the levels of adiponectin, intercellular adhesion molecule-1 (ICAM-1), tumour necrosis factor-alpha (TNF-alpha) and heart-type fatty acid-binding protein (H-FABP) in coronary atherosclerotic plaque specimens.

Aim: To analyse tissue levels of adiponectin, ICAM-1, TNF-alpha and H-FABP in the plaques obtained from coronary artery bypass grafting (CABG) and to evaluate whether there is any relationship between these variables and other characteristics.

Patients And Methods: Coronary artery specimens from 37 consecutive patients (28 men and nine women) at time of CABG procedure and preprocedural blood samples were obtained.

Background: Angiotensin-converting enzyme inhibitors, calcium channel blockers, and preoperative intravenous heparin use are independent risk factors for vasoplegic syndrome after cardiac surgery. We prospectively studied whether preoperative methylene blue administration would prevent the vasoplegic syndrome in these high-risk patients.

Methods: One hundred patients scheduled for coronary artery bypass graft surgery who were at high risk for vasoplegia because they were preoperatively using angiotensin-converting enzyme inhibitors, calcium channel blockers, and heparin were randomly assigned to either receive preoperative methylene blue (group 1, n = 50) or not receive it (group 2, controls, n = 50).

During mitral valve replacement, total chordae preservation is very important for left ventricular functions. But leaving anterior leaflet and chordae may cause serious complications, such as left ventricular outflow tract obstruction and impairment in prosthetic valve functions. In this article, we present the anterior leaflet preservation technique by excising the central portion of the anterior leaflet.
