OBJECTIVES This study was conducted to assess the diagnostic role of Doppler echocardiography in constrictive pericarditis. BACKGROUND It has been observed that patients with constrictive pericarditis have a characteristic Doppler pattern of respiratory variation in ventricular filling and central venous flow velocities. However, the observation was based on a small number of patients with kn...

Background—Constrictive pericarditis represents a serious hemodynamic syndrome that may lead to heart failure. Studies of its pathophysiological mechanisms have been impeded by the lack of an animal model. Methods and Results—Cardiac myosin–induced experimental autoimmune myocarditis in interferon (IFN)– knockout (KO) mice results in increased cardiac inflammation and development of severe gros...

SIXTY-EIGHT patients with constrictive pericarditis were studied by this laboratory in a 30-year period. During this time 14 patients were encountered whose findings suggested constrictive pericarditis but who showed an abnormal myocardium at operation or autopsy. Two of these patients had both constrictive pericarditis and myocardial fibrosis, each of the other 12 had a no: mal pericardium. Th...

amenorrhea, an absence of menses is a symptom that generally brings teenagers for evaluation. this study was undertaken to determine the etiology of primary amenorrhea with especial concern to non classic congential adrenal hyperplasia (nc-cah)-due 21 hydroxylase deficiency among female adolescents refered to clinics of pediatric endocrinology of tehran and iran university of medical sciences a...

INTRODUCTION Constrictive pericarditis is a heterogeneous disease with many causes. Traumatic hemopericardium is an uncommon initiating cause. We report the case of a man developing constrictive pericarditis after blunt chest trauma, in order to highlight an approach to diagnosing the condition and to raise awareness of the possibility of this condition developing after blunt trauma. CASE PRE...

Twenty-five syndactylous Angus cattle, characterized pathologically, were reported from 16 herds in 10 states from 1979 to 1994. Twenty-one (84%) had all 4 legs syndactylous, 3 (12%) had 3 legs syndactylous, and 1 (4%) had 2 legs syndactylous. All syndactylous cattle walked with considerable difficulty. Hooves of aged animals became curled and bent laterally or medially. Affected hooves had the...

THE ASSOCIATION of rheumatoid states with pericarditis is known."2 Coincidence of rheumatoid arthritis and chronic constrictive pericarditis is uncommon and represents a fascinating study in the pathogenesis of pericardial constriction. Repeated episodes of acute pericarditis associated with migratory polyarthritis and gradual development of constrictive pericarditis can seldom be documented. A...

Constrictive pericardial disease developing after open heart surgery is not a well-recognized complication of this procedure. It has been reported only a few times and usually not with good hemodynamic data before and after the subsequent pericardiectomy. We presently report a patient who developed constrictive pericardial disease five years after mitral valve replacement. This was documented w...

BACKGROUND In 1992, the concept of female athlete triad was introduced to describe the interrelated problems of amenorrhea, eating disorders and osteoporosis seen in female athletes. To gain a clearer picture of amenorrhea/oligomenorrhea in Iran, one of the main components of the female athlete triad, we therefore established this study on the prevalence of amenorrhea/oligomenorrhea in elite Ir...

OBJECTIVE Amenorrhea is a DSM-IV criterion for the diagnosis of anorexia nervosa (AN). Several studies have reported few differences between patients who meet the full DSM-IV criteria for AN and those who meet all but the amenorrhea criterion. Although this suggests that the absence of menses does not provide critical diagnostic information, many of these studies are limited by small sample siz...
