IgE bound to mast cells are stimulated by pollen and dust, causing the release of inflammatory mediators such as histamine. [18] Histamine dilates blood vessels in the nose that increases vascular permeability to fluid and cause fluid leakage leading to rhinorrhea [19]. In the nasal cavities, these inflammatory mediators cause inflammation and ...
Hemoglobinuria is a condition in which the oxygen transport protein hemoglobin is found in abnormally high concentrations in the urine. [1] The condition is caused by excessive intravascular hemolysis, in which large numbers of red blood cells (RBCs) are destroyed, thereby releasing free hemoglobin into the plasma. [2]
In highly concentrated urine they may shrivel and develop a spiky shape, which is termed crenation, while in dilute urine they can swell and lose their hemoglobin, creating a faint outline known as a ghost cell. A small quantity of red blood cells in the urine is considered normal. [93] [97] An increased level of RBCs is termed hematuria.

For instance, cloudy or milky urine usually accompanied by bad smell possibly indicates urinary tract infection, [1] excessive discharge of crystals, fat, white blood cells, red blood cells, or mucus.

“The only two places that blood can go when you have a nosebleed are from the front of the nose or down the back of the nose and into the throat,” says Dr. Edwards.
Hematuria can be classified according to visibility, anatomical origin, and timing of blood during urination. [1] [6]In terms of visibility, hematuria can be visible to the naked eye (termed "gross hematuria") and may appear red or brown (sometimes referred to as tea-colored), or it can be microscopic (i.e. not visible but detected with a microscope or laboratory test).
