TREATMENT OPTIONS There is NO cure for sickle cell disease‚ although new stem cell research is promising. Bone marrow transplant is a potential cure‚ however finding a matched sibling donor is difficult. Therefore treatment is primarily focused on management of symptoms and prevention of pain episodes. Hydroxyurea (a chemotherapeutic medication) is the only recognized treatment option for the prevention of vaso-occlusive crisis in SCD. It is a prescribed drug for adult patients

INTEGUMENTARY SYSTEM Skin and its derivatives and appendages form the integumentary system. In humans‚ skin derivatives include nails‚ hair‚ and several types of sweat and sebaceous glands. Skin‚ orintegument‚consists of two distinct regions‚ the superficial epidermis and a deep dermis. The superficialepidermis is nonvascular and lined by keratinized stratified squamous epithelium with distinct cell types and cell layers. Inferior to the epidermis is the vascular dermis‚ which is characterized by
