PURPOSE OF REVIEW We present an update on amenorrhea in adolescent girls and young women. Amenorrhea may herald the onset of estrogen deficiency, which can adversely affect peak bone mass and ultimate risk of osteoporosis. RECENT FINDINGS Adolescence is a critical period for bone accretion. Important modifiable factors that optimize bone accretion during this time are calcium intake, vitamin ...

It is difficult to distinguish between restrictive cardiomyopathy and constrictive pericarditis on the basis of clinical findings and simple investigation. Cardiac catheterisation has been the reference standard for diagnosis but even this does not always permit an accurate distinction. A Summagraphics digitiser and Prime 750 computer system were used to digitise the echocardiograms of 15 patie...

Systolic time intervals in 15 patients with constrictive pericarditis and seven patients with restrictive cardiomyopathy were compared in order to assess their value in the differential diagnosis of the two disorders. Clinical examination had failed to make the distinction. Right heart catheterization was helpful in diagnosing restriction but failed to differentiate patients with constrictive p...

Because of the close anatomic association, the volume or pressure in one ventricle can directly influence the volume and pressure in the other ventricle. Disease states that reduce pericardial compliance should accentuate this coupling between the ventricles. We examined this hypothesis in six dogs. Constrictive pericarditis was induced by injecting an irritant mixture into the pericardial cavi...

Between 1955 and 1972, eight children receiving mediastinal irradiation for intrathoracic malignancy developed constrictive pericarditis. Six of these followed irradiation for Hodgkin's disease and represent 7% of 86 children receiving irradiation for that disease. In patients with Hodgkin's disease, the development of constrictive pericarditis was related to the dose of radiation and the use o...

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)-gamma-knockout (KO) mice results in increased cardiac inflammation and development of seve...

BACKGROUND AND OBJECTIVES Tuberculous (TB) pericarditis is a major cause of constrictive pericarditis requiring pericardiectomy. We sought to determine initial prognostic factors in patients with TB pericarditis. SUBJECTS AND METHODS We evaluated initial presentation and clinical outcomes (mean follow-up 32±27 months) in 60 consecutive patients newly diagnosed with TB pericarditis. RESULTS ...

conclusions cmr with stir sequences, free breathing sequences and late gadolinium imaging can prove extremely useful for diagnosing constrictive pericarditis. case presentation a 77-year-old man from a country with high incidence of tuberculosis presented with severe dyspnea. echocardiography revealed a small left ventricle with normal systolic and mildly impaired diastolic function. left heart...

gestational choriocarcinoma usually occurs following an intrauterine pregnancy. we report a case of metastatic choriocarcinoma to the left kidney and lungs with long term intermittent amenorrhea and vaginal bleeding after a normal vaginal delivery. a 43 year old rural woman presented with three years intermittent amenorrhea and vaginal bleeding following normal vaginal delivery. she also compla...

background: female genital tuberculosis is an important cause of secondary amenorrhea and infertility in developing countries where tuberculosis is endemic. objectives: we present three cases in which endometrial tuberculosis was a cause of secondary amenorrhea and infertility.rnpatients and methods: in a retrospective study from january 2007 to june 2010, we conducted 1010 laparoscopies for in...
