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.
The first step is to see if you have pigmentation issues -not really classed as acne scars, but this is controversial, or if you have contour changes. The best thing to do is to examine under tangential or angled lighting, as this will reveal all. Once this is done, scars can be subtyped and mapped, with high resolution photos. The second aspect, which is equally as important is to examine scars upon animanation, namely when you speak, smile and move your face. This will give me an idea of the amount of tethering and anchored acne scars. Time and time again I get request for ‘what is the treatment’ with static photos, an impossible task to answer correctly. Acne scar assessment has to be done live- with the patient in front of you, and lighting from all angles. Photos do not map scars as well a real time examination under magnification and lighting.
Sepsis occurs when chemicals released in the bloodstream to fight an infection trigger inflammation throughout the body. This can cause a cascade of changes that damage multiple organ systems, leading them to fail, sometimes even resulting in death. Symptoms include fever, difficulty breathing, low blood pressure, fast heart rate, and mental confusion. Treatment includes antibiotics and intravenous fluids.
A decade ago we thought that Chikungunya was a tropical disease restricted to the rain forests. However, after the 2007 epidemic in Italy and later in the Reunion islands, this dreaded condition has now spread to the Carribean and the Americas. Its an arthropod borne alpha virus which causes fever, polyarthralgia and arthritis. There could be serious complications in the adult such as meningoencephalitis or GBS as well as in neonates. This presentation discusses in detail the clinical features, diagnosis and management of Chikungunya fever. A detailed discussion of its complications is also included. Check out our other videos

Dr. Ankur Gupta of the Virginia Eye Institute discusses LASIK eye surgery as a method of correcting refractive errors. LASIK was first performed in Virginia on an FDA-approved laser by a VEI surgeon in 1996. Today, Virginia Eye Institute offers both conventional LASIK and custom LASIK with the bladeless IntraLase laser to precisely sculpt your cornea to correct refractive errors.

Observation of both jugular veins can provide a reliable indication of the volume and pressure in the right side of the heart since internal jugular veins pulsate in response to phasic changes in right atrial pressure. Proper positioning of the patient to increase the effects of gravity enhances distention of the jugular veins and, therefore, increases the ability to observe venous pulsations.
