Health What Is a Posterior Nosebleed? Medically reviewed by  Debra Sullivan, Ph.D., MSN, R.N., CNE, COI  —  Written by  Tim Jewell   Causes Treatment Do’s and don’ts When to see your doctor What is a posterior nosebleed? When the tissue at the back of your nose in your nasal cavity is damaged and bleeds, it’s called a posterior nosebleed. Blood may come out of your nostrils, but blood can also leak into your throat. This type of nosebleed can be serious. It may be caused by injuries to your nose, but may also be caused by high blood pressure or other conditions. You likely have a posterior nosebleed if blood comes out of your nose for more than 20 minutes or the nosebleed happens after you’ve gotten a head, nose, or face injury. Posterior nosebleeds are also more common in children between 2 and 10 years old and adults between 50 and 80 years old. A nosebleed, also known as epistaxis, can happen for a number of reasons. They’re most common when the blood vessels in the tissue of the in

Health Endometriosis By : Vishnu /15.5.21 Symptoms Treatment Causes Stages Diagnosis Complications Risk factors Outlook What is endometriosis? Endometriosis is a disorder in which tissue similar to the tissue that forms the lining of your uterus grows outside of your uterine cavity. The lining of your uterus is called the endometrium. Endometriosis occurs when endometrial tissue grows on your ovaries, bowel, and tissues lining your pelvis. It’s unusual for endometrial tissue to spread beyond your pelvic region, but it’s not impossible. Endometrial tissue growing outside of your uterus is known as an endometrial implant. The hormonal changes of your menstrual cycle affect the misplaced endometrial tissue, causing the area to become inflamed and painful. This means the tissue will grow, thicken, and break down. Over time, the tissue that has broken down has nowhere to go and becomes trapped in your pelvis. This tissue trapped in your pelvis can cause: irritation scar formation adhesions

Health Male hormones regulate stomach inflammation in mice Glucocorticoids and androgens promote a healthy stomach pit by inhibiting inflammation, left, while their absence promotes inflammation and SPEM seen in a diseased pit, right. SPEM glands are also much larger than healthy stomach glands. Jonathan Busada, Ph.D./NIEHS Scientists at the National Institutes of Health determined that stomach inflammation is regulated differently in male and female mice after finding that androgens, or male sex hormones, play a critical role in preventing inflammation in the stomach. The finding suggests that physicians could consider treating male patients with stomach inflammation differently than female patients with the same condition. The study was published in Gastroenterology. Researchers at NIH’s National Institute of Environmental Health Sciences (NIEHS) made the discovery after removing adrenal glands from mice of both sexes. Adrenal glands produce glucocorticoids, hormones

Health Mucormycosis What is mucormycosis? Mucormycosis (sometimes called zygomycosis) is a serious but rare fungal infection caused by a group of molds called mucormycetes.  These fungi live throughout the environment, particularly in soil and in decaying organic matter, such as leaves, compost piles, or rotten wood.   1 People get mucormycosis by coming in contact with the fungal spores in the environment. For example, the lung or sinus forms of the infection can occur after someone breathes in spores. These forms of mucormycosis usually occur in people who have health problems or take medicines that lower the body’s ability to fight germs and sickness.   3 , 6  Mucormycosis can also develop on the skin after the fungus enters the skin through a cut, scrape, burn, or other type of skin trauma. Types of mucormycosis Rhinocerebral (sinus and brain) mucormycosis  is an infection in the sinuses that can spread to the brain. This form of mucormycosis is most common in people with uncontrol

Health Fungal diseases  About fungal diseases . Fungi are everywhere. Sometimes, they are too small to see with the naked eye. Fungi live: Outdoors, for example, in soil and on plants Indoors, on surfaces and in the air On people’s skin and inside the body There are millions of fungal species, but only a few hundred of them can make people sick. Molds, yeasts, and mushrooms are all types of fungi. Fungi can cause many different types of illnesses, including: Asthma or allergies.  Learn more about mold and how it can affect your health.
