Overview - Infectious diseases Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They're normally harmless or even helpful, but under certain conditions, some organisms may cause disease. Some infectious diseases can be passed from person to person. Signs and symptoms vary depending on the organism causing the infection, but often include fever and fatigue. Many infectious diseases, such as measles and chickenpox, can be prevented by vaccines.

A migraine headache is a primary headache disorder that effects approximately 12% of the population. It is a headache that tends to recur in an individual and is moderate to severe if left untreated. It can be one sided, throbbing and aggravated by routine physical activity. It can be associated with light and sound and even smell sensitivity and many patients will become nauseated with it.. In a minority of patients there can be visual or sensory changes before, during or after the headache, known as auras. Who is affected by migraines? The National Headache Foundation estimates that nearly 30 million Americans suffer from migraines. What causes a migraine? The exact causes of migraines are unknown, although they are related to changes in the brain as well as to genetic causes. For many years, scientists believed that migraines were linked to the expanding (dilation) and constriction (narrowing) of blood vessels on the brain’s surface. Caffeine. Tension Fatigue
Working kidney created in bioengineering lab | Crave There just aren't enough donated organs to fill the need. That's why scientists have been dreaming of growing transplantable organs in labs. Scientists at the Massachusetts General Hospital Center for Regenerative Medicine have made a step forward by creating a functional rat kidney. The process is not quite as futuristic as growing a whole organ from scratch. The next step involves regenerating the organ by inserting viable cells from the recipient rat using a vacuum process. The organ is placed in a chamber that mimics the environment of a body. This isn't the first time researchers have developed bioengineered rat organs. Though the kidney work is promising, it's still early days. Ultimately, the process could turn nonviable organs into working organs that are designed to match each patient. (Via Txchnologist)
Diseases and Organisms in Healthcare Settings | HAI Acinetobacter Acinetobacter [asz−in−ée−toe–back−ter] is a group of bacteria commonly found in soil and water. Outbreaks of Acinetobacter infections typically occur in intensive care units and healthcare settings housing very ill patients. While there are many types or “species” of Acinetobacter and all can cause human disease, Acinetobacter baumannii [asz−in−ée−toe–back−ter bō–maa–nee–ie] accounts for about 80% of reported infections.

MedlinePlus: Headache Almost everyone has had a headache. Headache is the most common form of pain. It's a major reason people miss days at work or school or visit the doctor. The most common type of headache is a tension headache. Other common types of headaches include migraines, cluster headaches, and sinus headaches. Not all headaches require a doctor's attention. NIH: National Institute of Neurological Disorders and Stroke ENY-740/IN722: Emerging Infectious Diseases Infectious diseases are illnesses caused by the presence and activity of one or more pathogenic agents, including viruses, bacteria, fungi, protozoa, multicellular parasites, and abnormal proteins called prions. They are transmitted through a variety of means including direct or indirect contact; ingestion (in water or food); transmission of body fluids; inhalation of airborne particles and droplets; transmission by vectors such as mosquitoes, fleas, and ticks; and others. What Are Emerging Infectious Diseases Emerging infectious diseases (EID) are those that have newly appeared or that have existed in the past but are now rapidly increasing in frequency, geographic range, or both. The US Institute of Medicine defines emerging infections as: "those whose incidence in humans has increased within the past two decades or threatens to increase in the near future. Some Examples of Emerging Infectious Diseases Figure 1. Triatomine bugs can transmit Chagas disease. Credit: S.A. Figure 2. Figure 3.
RSS Feeds Submission Directory › RSS - ReadWriteWeb Free, unencrypted wireless is everywhere, but you shouldn't be checking your bank account on it unless you don’t mind somebody else snooping. The solution? A virtual private network, or VPN. A VPN extends your own private network into public places, so even if you’re using Starbucks' Wi-Fi connection, your Internet browsing stays encrypted and secure. There are plenty of ways to set up a VPN, both with free and paid services, but each solution has its own pros and cons, determined by the way the VPN provider operates and charges and the kinds of VPN options it provides. The easiest and cheapest solution to keep your data safe is to just abstain from public Wi-Fi completely. My Raspberry Pi is about the size of a smartphone, but it runs a fully functional VPN server. This is the part where I’d link you to a handy tutorial on how to set this up. Materials Hardware Raspberry Pi Model B: Plus everything that comes with it—by that, I mean a regular power source and a case to put it in. Software .
Rx for Survival . Deadly Diseases Diarrheal Diseases Over the past 150 years, sanitation engineers have dramatically reduced epidemics of cholera, diarrheal dehydration, amoebic dysentery, and typhoid. Still, nearly 1.1 billion people lack access to clean drinking water. In the 1980s, aggressive medical detective work revealed the causes of HIV/AIDS, debunking several myths about the disease and its victims. Influenza Each year the common flu takes the lives of between 250,000 and 500,000 people worldwide. Malaria This disease, once believed to be caused by mala aria, or "bad air," is actually spread by the female Anopheles mosquito, a dangerous parasite-carrying agent. Malnutrition This disease is typically misunderstood as a lack of food. Measles The world's most contagious disease can be prevented by a vaccine that costs a mere 26 cents per dose. Plague Memorialized in the writings of John Donne and children's songs like "Ring Around the Rosy," the plague seems like a disease of a distant century. Pneumonia Polio Smallpox
