Anthrax in animals rarely occurs in the United States because of that human anthrax is rare in the US.Anthrax infection can occur in three forms: cutaneous (skin)‚ inhalation‚ and gastrointestinal. Spores of the bacterium B. anthracis can live in the soil for many years‚ and livestock can become infected by grazing on contaminated pasture. Humans can become infected with anthrax by handling infected

necrolysis- A case report. Introduction: Toxic epidermal necrolysis‚ also known as Lyell’s syndrome as it was described by Alan Lyell in 1956 who was a Scottish dermatologist. (1) Even though it is a rare but also a serious type of cutaneous adverse drug reaction. It is often characterized by widespread erythema‚ necrosis‚ and bullous detachment of the epidermis and mucous membranes. That results in exfoliation of Epidermis which leaves an exposed and inflamed dermis and therefore there

The living world is divided into the five kingdoms of Planta‚ Animalia‚ Fungi‚ Protista and Monera. It is important to recognize that the fungi are not related to bacteria (Monera). To define the exact limits of the groups in a few words is virtually impossible‚ however generally speaking fungi are eukaryotica‚ heterotrophicb‚ unicellular to filamentous‚ rigid

Neuroblastoma is one of the most common childhood malignancies. Patients diagnosed under 1 years of age [40%] have a much better prognosis than those diagnosed in later childhood. Neuroblastoma originates from neural crest cells of the adrenal medulla or sympathetic ganglia. Neuroblastomas commonly present as an asymptomatic mass in a child. The treatment of neuroblastoma depends on the stage‚ and it includes surgical excision‚ multiagent chemotherapy‚ and bone marrow transplantation. Key words :
