Hypothalamus and Pituitary
Hypothalamus and Pituitary samer kareem 4,508 Views • 2 years ago

The pituitary gland is often portrayed as the "master gland" of the body. Such praise is justified in the sense that the anterior and posterior pituitary secrete a battery of hormones that collectively influence all cells and affect virtually all physiologic processes. The pituitary gland may be king, but the power behind the throne is clearly the hypothalamus. As alluded to in the last section, some of the neurons within the hypothalamus - neurosecretory neurons - secrete hormones that strictly control secretion of hormones from the anterior pituitary. The hypothalamic hormones are referred to as releasing hormones and inhibiting hormones, reflecting their influence on anterior pituitary hormones.

Thrombotic thrombocytopenic purpura (TTP) is a rare blood disorder characterized by clotting in small blood vessels of the body (thromboses), resulting in a low platelet count. In its full-blown form, the disease consists of the pentad of microangiopathic hemolytic anemia, thrombocytopenic purpura, neurologic abnormalities, fever, and renal disease

Constrictive pericarditis versus restrictive cardiomyopathy
Constrictive pericarditis versus restrictive cardiomyopathy samer kareem 6,805 Views • 2 years ago

Constrictive pericarditis is the result of scarring and consequent loss of the normal elasticity of the pericardial sac. This leads to impairment of ventricular filling in mid and late diastole. As a result, the majority of ventricular filling occurs rapidly in early diastole and the ventricular volume does not increase after the end of the early filling period. Restrictive cardiomyopathy is characterized by a nondilated rigid ventricle, resulting in severe diastolic dysfunction and restrictive filling that produces hemodynamic changes similar to those in constrictive pericarditis. Constrictive pericarditis and restrictive cardiomyopathy both lead to diastolic heart failure with normal (or near normal) systolic function, and characteristically abnormal ventricular filling that results in similar clinical and hemodynamic features. However, because of their markedly different treatments, differentiating between the two conditions is critical. In some patients, the correct diagnosis may be readily suggested from the history or routine diagnostic testing. In others, however, this differentiation cannot be diagnosed before biopsy or even surgical exploration.

ReLEx SMILE: Minimally invasive laser eye surgery Mohamed Ibrahim 91 Views • 2 years ago

This video shows Prof Dan Reinstein, MD MA(Cantab) FRCSC DABO FRCOphth FEBO performing a ReLEx SMILE keyhole LASIK procedure using the latest surgical instrument that he helped to develop (Malosa MMSU1297 - Reinstein Lenticule Separator: http://www.malosa.com/en/reinstein-le...). This instrument enables the procedure to be performed with one instrument, through one 2mm incision, using only one sweep per plane, and taking about 30 seconds to separate and withdraw the lenticule, improving day 1 uncorrected vision over other lenticule extraction techniques that require more corneal manipulation.
