Osteonecrosis of the jaws (ONJ) is a condition characterized by necrotic exposed bone in the jaws of patients receiving intravenous or oral bisphosphonate therapy. A review of the medical and dental literature reveals that the pathoetiology of ONJ remains unknown and there is no established link that bisphosphonates are the primary cause of this bone pathology. However, there is clinical evidence that Actinomyces may play a critical role in the pathogenesis of bisphosphonate-associated ONJ. Identification

late, or some other stimulus occurs Haemophilus Influenzae springs into effect and performs the task that it arrived for. Other treatments once the disease is active include antibiotics and remain away from the workplace, so as not to spread the bacteria around a workplace or school. It’s especially important that someone with Haemophilus Influenzae remain away from anyone with a weak immune system such as those who are already ill, infants, and older people as they are especially susceptible.

Bacteria |I | |INTRODUCTION | Bacteria, one-celled organisms visible only through a microscope. Bacteria live all around us and within us. The air is filled with bacteria, and they have even entered outer space in spacecraft. Bacteria live in the deepest parts of the ocean and deep within Earth. They are in the soil, in our food, and on plants and animals. Even our bodies are home to many different kinds of bacteria. Our lives are closely intertwined with theirs, and the health

Epidemiology: Chickenpox The Varicella-Zoster virus causes a very infectious disease called Chickenpox. Chickenpox is usually acquired through the inhalation of airborne respiratory droplets from an infected host.

Pathophysiology of cellulitis in adults. Cellulitis, a bacterial infection of the skin and underlying tissue, is a common presentation to Emergency Departments (ED). The clinical spectrum of presentation can vary from local inflammation to diffuse inflammation involving a whole limb, to more severe, even life threatening presentations of necrotizing fascitis and associated sepsis. The rationale for choosing this condition is to enable me to efficiently differentiate between those cases that
