Applying the fully integrated relationship between financial stocks and flows allows for a more refined analysis of the deterministic components that make up the 'stock-flow' residual. Using partial measures of these stock-flow(More)
Breakthrough pain (BKP) is a transitory flare of pain that occurs on a background of relatively well controlled baseline pain. Previous surveys have found that BKP is highly prevalent among patients with cancer pain and predicts more severe pain, pain-related distress and functional impairment, and relatively poor quality of life.

This study aimed to determine the prevalence of alexithymic characteristics in patients with systemic lupus erythematosus (SLE), comparing them with a population of healthy subjects. Fifty-three SLE patients [American College of Rheumatology (ACR) criteria] and 31 healthy volunteer subjects were administered validated scales for alexithymia (Toronto(More)
BACKGROUND CD4+CD25+ regulatory T cells play an essential role in maintaining immune homeostasis and preventing autoimmunity. Therefore, defects in Treg development, maintenance or function have been associated with several human autoimmune diseases including Systemic Lupus Erythematosus (SLE), a systemic autoimmune disease characterized by loss of(More)
Myxomas are the most common type of benign cardiac tumor. The most frequent clinical presentations are symptoms resulting from atrioventricular valve obstruction or systemic embolization.

A useful but little known feature of the IMF's Government Finance Statistics Yearbook (GFSY) is the information on the structure of governments. Institutional tables, included in the GFSY, provide detail on the central, state, and local levels of governments, social security, and extrabudgetary units.

Constrictive pericarditis is a clinical condition characterized by the appearance of signs and symptoms of right heart failure due to loss of pericardial compliance. Cardiac surgery is now one of the most frequent causes in developed countries, while tuberculosis remains the most prevalent cause in developing countries. Malignancy is a rare cause but(More)
Calcification of the mitral annulus is a common echocardiographic finding during routine evaluation of patients. Caseous calcification of the mitral annulus (CCMA) on the other hand is a rare variant, occurring in about 0.06-0.07% of echocardiographic studies. The authors present the case of a 73-year-old woman admitted to hospital with an anterior wall(More)
