Microhematuria, also called microscopic hematuria (both usually abbreviated as MH), is a medical condition in which urine contains small amounts of blood; the blood quantity is too low to change the color of the urine (otherwise, it is known as gross hematuria).
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).
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes R80-R82 within Chapter XVIII: Symptoms, signs and abnormal clinical and laboratory findings should be included in this category.
The signs and symptoms of this disorder can vary from asymptomatic microhematuria to severe, recurrent flank pain associated with kidney stone formation and infections. Patients may also present with a fever, nausea, vomiting, dysuria and polyuria. [6] If untreated, the chronic infections can progress causing renal damage.
IgA nephropathy (IgAN), also known as Berger's disease (/ b ɛər ˈ ʒ eɪ /) (and variations), or synpharyngitic glomerulonephritis, is a disease of the kidney (or nephropathy) and the immune system; specifically it is a form of glomerulonephritis or an inflammation of the glomeruli of the kidney.
There was microhematuria and, on rare occasions, hematuria. Even in the most severe cases, significant improvements and even recovery within 1-2 weeks was feasible. Heart paralysis, uncontrollable hemorrhages, suffocation, pneumonia with pulmonary abscesses, and gangrene all contributed to death. [2]
Microhematuria was observed in 51% of the patients. Neurotoxic symptoms (ptosis, ophthalmoplegia, bulbar paralysis, and peripheral muscular weakness) developed in 85%. Endotracheal intubation was required in 42% and mechanical ventilation by 37%.
EA-3834 is a potent anticholinergic deliriant drug with a fairly long duration of action, related to the chemical warfare agent 3-quinuclidinyl benzilate (QNB). It was developed under contract to Edgewood Arsenal during the 1960s as part of the US military chemical weapons program, during research to improve upon the properties of earlier agents such as QNB.
