during a period of four years between june, is, 1988 to june, is, 1992 one hundred and fourteen patients with congestive heart failure (chf) were admitted to the pediatric department of taleghani general hospital. during the above period, 192 patients with heart disease were hospitalized at this department and chf was the cause of admission in 59.4% of them. congenital heart disease (cho) was t...

Aortic tears commonly occur in multiply injured patients. Recognizing this injury is important. A chest X-ray is helpful and a CT-angiogram or aortogram confirmatory. After attending to life-threatening injuries, the aortic tear should be repaired immediately. Using the left heart bypass technique has the lowest risk of operative neurologic injury. We review our experience over the last 2 years...

In this paper, a mathematical model for the description of cerebral hemodynamics is developed. This model is able to simulate the regulation mechanisms working on the small cerebral arteries and arterioles, and thus to adapt dynamically the blood flow in brain. Special interest is laid on the release of catecholamines and their effect on heart frequency, cardiac output and blood pressure. There...

Right atrial laceration is described as a complication of external cardiac massage in two patients. In each there was a pre-existent cause of weakness of the atrial wall. There was pronounced right atrial dilation with attenuation of the wall in one case, and in the other there was a granulomatous myocarditis involving the atrial wall. The significance of atrial laceration as a complication of ...

Mr. Maingot has collected together the contributions from the pen of 29 front ranking British surgeons and each has written on his own specialty. The subjects include the most recent advances in the surgical fields such as congenital heart disease, vagal resection, retropubic prostatectomy, nerve suture, hypospadias, Parkinson's disease, etc., as well as those not so recent such as intestinal o...

Heart valve injuries due to non-penetrating blunt thoracic trauma are rare. Isolated tricuspid incompetence due to detachment of a leaflet from the annulus after blunt trauma is uncommon. Young patients may tolerate chronic tricuspid regurgitation (TR), and can be undiagnosed for years until the right ventricular failure occurs. We report the case of a young adult male who sustained blunt chest...

post-traumatic stress disorder (ptsd) is a chronic and progressive disorder that occurs after some traumas and accident. injuries and harm to health caused by motor vehicle accidents (mvas) have become an issue of global concern, as mvas are expected to be the third largest contributor to the worldwide burden of disease by the year 2020. chronic ptsd is a common consequence of mva and that it m...

Introduction: Wheelchairs are the prime mobility aid of persons with spinal cord injuries. Manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. The main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during whe...

Background: Statins are hydroxymethylglutaryl coenzyme A reductase inhibitors that reduce intracellular cholesterol synthesis by competitively inhibiting endogenous cholesterol synthesis rate limiting enzymes. Currently they are most used in the prevention of coronary heart disease. Aside on their cholesterol-lowering effect, statins are also anti-inflammatory in terms of their effects. Recent ...

Background Heart valve injuries due to non-penetrating blunt thoracic trauma are rare with aortic valve being the most vulnerable. Tricuspid valve injury resulting in severe regurgitation is unusual after blunt chest trauma. Two major issues for the management of traumatic tricuspid regurgitation are timing and type of the operation. Valve repair is naturally the first choice but valve replacem...
