Hemorrhoids (HEM-uh-roids), also called piles, are swollen veins in your anus and lower rectum, similar to varicose veins. Hemorrhoids have a number of causes, although often the cause is unknown. They may result from straining during bowel movements or from the increased pressure on these veins during pregnancy.

Over one million Americans have the sexually transmitted virus, HIV, which can lead to the deadly disease known as AIDS.
HIV can be transmitted in the sexual fluids, blood or breast milk of an infected person. HIV prevention therefore involves a wide range of activities including prevention of mother-to-child transmission, needle exchanges and harm reduction for injecting drug users, and precautions for health care workers.
systemic inflammatory response syndrome (SIRS). This is most likely secondary to sepsis from an infection of the patient's Hickman catheter given the associated skin findings, although culture results are needed to confirm this diagnosis. The patient's low blood pressure is likely secondary to developing septic shock, and he has already appropriately been treated with intravenous fluids. Catheter removal is indicated given his hemodynamic instability. Catheter removal is also indicated in patients with severe sepsis with organ hypoperfusion, endocarditis, suppurative thrombophlebitis, or persistent bacteremia after 72 hours of appropriate antibiotic therapy. Long term catheters should also be removed if culture results are positive for S. aureus, P. aeruginosa, fungi, or mycobacteria.
Shaken baby syndrome — also known as abusive head trauma, shaken impact syndrome, inflicted head injury or whiplash shake syndrome — is a serious brain injury resulting from forcefully shaking an infant or toddler. Shaken baby syndrome destroys a child's brain cells and prevents his or her brain from getting enough oxygen. Shaken baby syndrome is a form of child abuse that can result in permanent brain damage or death. Shaken baby syndrome is preventable. Help is available for parents who are at risk of harming a child. Parents also can educate other caregivers about the dangers of shaken baby syndrome.

Schistosomiasis is a parasitic disease caused by flukes (trematodes) of the genus Schistosoma. After malaria and intestinal helminthiasis, schistosomiasis is the third most devastating tropical disease in the world, being a major source of morbidity and mortality for developing countries in Africa, South America, the Caribbean, the Middle East, and Asia. (See Epidemiology and Prognosis.) [1] More than 207 million people, 85% of who live in Africa, are infected with schistosomiasis, [1] and an estimated 700 million people are at risk of infection in 76 countries where the disease is considered endemic, as their agricultural work, domestic chores, and recreational activities expose them to infested water. [1, 2] Globally, 200,000 deaths are attributed to schistosomiasis annually. [3] Transmission is interrupted in some countries. [2] (See Etiology and Epidemiology.)
James Burke Fine DMD by James Burke Fine DMD Periodontal disease is a gum condition caused by the buildup of bacteria along and below the teeth's gumline. Acute forms are usually associated with pain from oral tissue gone bad – also known as necrotizing gingivitis or trench mouth – whereas chronic forms are painless but have a more long-term impact on your overall, systemic health. The most common chronic form is gingivitis, whose bleeding, puffiness and redness comes from an organized mass of bacteria called plaque. You may know it can advance into a form called periodontitis. If these conditions are left untreated, however, it can also lead to infections within other parts of the body, such as the lungs.
