Giant Blackheads Removal
Giant Blackheads Removal Scott 36,694 Views • 2 years ago

What are blackheads? Blackheads are small bumps that appear on your skin due to clogged hair follicles. These bumps are called blackheads because the surface looks dark or black. Blackheads are a mild type of acne that usually form on the face, but they can also appear on the following body parts: back chest neck arms shoulders Acne affects nearly 50 million Americans and is the most common skin disorder in the United States, according to the American Academy of Dermatology. What do blackheads look like? What causes blackheads? Blackheads form when a clog or plug develops in the opening of hair follicles in your skin. Each follicle contains one hair and a sebaceous gland that produces oil. This oil, called sebum, helps keep your skin soft. Dead skin cells and oils collect in the opening to the skin follicle, producing a bump called a comedo. If the skin over the bump stays closed, the bump is called a whitehead. When the skin over the bump opens, exposure to the air causes it to look black and a blackhead forms. Some factors can increase your chances of developing acne and blackheads, including: producing too much body oil the buildup of the Propionibacterium acnes bacteria on the skin irritation of the hair follicles when dead skins cells don’t shed on a regular basis undergoing hormonal changes that cause an increase in oil production during the teen years, during menstruation, or while taking birth control pills taking certain drugs, such as corticosteroids, lithium, or androgens Some people believe that what you eat or drink can affect acne. Dairy products and foods that increase blood sugar levels, such as carbohydrates, may play a part in triggering acne, but researchers aren’t convinced that there’s a strong connection. ADVERTISING What are symptoms of blackheads? Because of their dark color, blackheads are easy to spot on the skin. They’re slightly raised, although they aren’t painful because they aren’t inflamed like pimples. Pimples form when bacteria invade the blockage in the hair follicle, causing redness and inflammation. How are blackheads treated? Over-the-counter (OTC) treatments Many acne medications are available at drug and grocery stores and online without a prescription. These medications are available in cream, gel, and pad form and are put directly on your skin. The drugs contain ingredients such as salicylic acid, benzoyl peroxide, and resorcinol. They work by killing bacteria, drying excess oil, and forcing the skin to shed dead skin cells. Prescription medications If OTC treatment doesn’t improve your acne, your doctor may suggest that you use stronger prescription medications. Medications that contain vitamin A keep plugs from forming in the hair follicles and promote more rapid turnover of skin cells. These medications are applied directly to your skin and can include tretinoin, tazarotene, or adapalene. Your doctor may also prescribe another type of topical medication that contains benzoyl peroxide and antibiotics. If you have pimples or acne cysts in addition to your blackheads, this type of medication may be particularly helpful. Manual removal Dermatologists or specially trained skin care professionals use a special instrument called a round loop extractor to remove the plug causing the blackhead. After a small opening is made in the plug, the doctor applies pressure with the extractor to remove the clog. Microdermabrasion During microdermabrasion, a doctor or skin care professional uses a special instrument that contains a rough surface to sand the top layers of your skin. Sanding the skin removes clogs that cause blackheads. Chemical peels Chemical peels also remove clogs and get rid of the dead skins cells that contribute to blackheads. During a peel, a strong chemical solution is applied to the skin. Over time, the top layers of the skin peel off, revealing smoother skin underneath. Mild peels are available over the counter, while stronger peels are performed by dermatologists or other skincare professionals. Laser and light therapy Laser and light therapies use tiny beams of intense light to decrease oil production or kill bacteria. Both lasers and light beams reach below the surface of the skin to treat blackheads and acne without damaging the top layers of the skin. How can blackheads be prevented? You can prevent blackheads without spending a lot of money by trying a few of the following ideas: Wash regularly Wash your face when you wake up and before you go to bed to remove oil buildup. Washing more than twice each day can irritate your skin and make your acne worse. Use a gentle cleanser that doesn’t make your skin red or irritated. Some acne cleansing products have antibacterial ingredients that kill P. acnes bacteria. Consider washing your hair every day, too, particularly if it’s oily. Hair oils can contribute to clogged pores. It’s also important to wash your face after you eat oily foods such as pizza, because oil from these foods can clog pores. Use oil-free products Any product that contains oil can contribute to new blackheads. Choose oil-free or noncomedogenic makeup, lotions, and sunscreens to avoid making your problem worse. Try an exfoliating product Exfoliating scrubs and masks remove dead skin cells from your face and can help reduce blackheads. Look for products that don’t irritate your skin.

This video: Multiple myeloma is a cancer that forms in a type of white blood cell called a plasma cell. Plasma cells help you fight infections by making antibodies that recognize and attack germs. Multiple myeloma causes cancer cells to accumulate in the bone marrow, where they crowd out healthy blood cells. Rather than produce helpful antibodies, the cancer cells produce abnormal proteins that can cause kidney problems. Treatment for multiple myeloma isn't always necessary. If you're not experiencing signs and symptoms, you may not require treatment. If signs and symptoms develop, a number of treatments can help control your multiple myeloma.

Keratoderma Blennorrhagicum is a manifestation on the skin that appears in patients diagnosed with reactive arthritis (this condition was previously known as Reiter syndrome). The condition manifests itself by lesions that appear on the skin, initially on the palm of the hands and soles of the feet. The lesions have the tendency to spread, affecting other parts of the body, such as the scrotum, scalp or trunk. Because of their appearance, the lesions might be easily confused with the ones from psoriasis. Keratoderma blennorrhagicum is one of the symptoms that can be used for the clinical diagnosis of reactive arthritis.

Neurotransmission
Neurotransmission samer kareem 1,485 Views • 2 years ago

Ca2+ binds with the membrane of the synaptic vesicles, which causes the vesicles to break and release the neurotransmitter into the synaptic cleft. After the neurotransmitters are released, they diffuse across the synaptic cleft and interact with receptors on the postsynaptic membrane. When the action potential reaches the presynaptic terminal, it provokes the release of a small quantity of neurotransmitter molecules, which bind to chemical receptor molecules located in the membrane of another neuron, the postsynaptic neuron, on the opposite side of the synaptic cleft.

Aneurysm in the Brain and Clipping
Aneurysm in the Brain and Clipping samer kareem 6,497 Views • 2 years ago

A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. When a brain aneurysm ruptures, the result is called a subarachnoid hemorrhage. Depending on the severity of the hemorrhage, brain damage or death may result. The most common location for brain aneurysms is in the network of blood vessels at the base of the brain called the circle of Willis. What causes a brain aneurysm? A person may inherit the tendency to form aneurysms, or aneurysms may develop because of hardening of the arteries (atherosclerosis) and aging. Some risk factors that can lead to brain aneurysms can be controlled, and others can't. The following risk factors may increase your risk for an aneurysm or, if you already have an aneurysm, may increase your risk of it rupturing: Family history. People who have a family history of brain aneurysms are more likely to have an aneurysm than those who don't. Previous aneurysm. People who have had a brain aneurysm are more likely to have another. Gender. Women are more likely to develop a brain aneurysm or to suffer a subarachnoid hemorrhage. Race. African Americans are more likely than whites to have a subarachnoid hemorrhage. High blood pressure. The risk of subarachnoid hemorrhage is greater in people who have a history of high blood pressure. Smoking. In addition to being a cause of high blood pressure, the use of cigarettes may greatly increase the chances of a brain aneurysm rupturing.

Patent ductus arteriosus (PDA)
Patent ductus arteriosus (PDA) samer kareem 1,861 Views • 2 years ago

Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby's circulatory system before birth that usually closes shortly after birth. If it remains open, however, it's called a patent ductus arteriosus. A small patent ductus arteriosus often doesn't cause problems and might never need treatment. However, a large patent ductus arteriosus left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure and other complications. Treatment options for a patent ductus arteriosus include monitoring, medications and closure by cardiac catheterization or surgery.
