Abstract

Schistosomiasis haemalobium is a major endemic parasitic disease in many tropical regions including Egypt. Typical infection results in haematuria, dysuria, anaemia, genital as well as urinary tract lesions, with prospect of kidney damage in complicated cases. In addition, deposited eggs in the tissue, eventually leads to squamous cell carcinoma of urinary bladder in chronically infected individuals. Microscopic detection of excreted ova in urine samples remains the gold standard diagnostic method, in spite of its inherited low sensitivity, inconsistent egg excretion and unreliable results in chronic phase of the disease. Moreover due to pre-requisite for skilled personals and pricey equipment, PCR-based technologies are of limited use especially in low-income endemic countries. So emergence of loop-mediated isothermal DNA amplification (LAMP) seemed a promising technique. Our study evaluated application of LAMP technique in detection of S. haematobium DNA in 69 urine samples of suspected patients for urogenital schistosomiasis, versus conventional urine filtration followed by microscopy ova detection method. Specificity of LAMP was tested using other parasites DNA samples that showed no cross reactivity. Furthermore our result...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
