Lymphomas: Types, causes, and more - Medical News Today

Image
Lymphoma is a type of cancer that begins in the lymphatic system, a network of organs, tissues, and vessels that produce, store, and carry white blood cells. These white blood cells are responsible for fighting infection and disease. Lymphomas occur due to changes to the DNA of white blood cells called lymphocytes. Many health experts categorize lymphoma into two major types : non-Hodgkin lymphoma and Hodgkin lymphoma. However, other specialists suggest there are three types, which include small lymphocytic lymphoma (SLL). However, some doctors consider SLL to be a subtype of non-Hodgkin lymphoma. This article describes what the lymphatic system is and how cancers can develop in this part of the body. It also outlines the types of lymphoma, including associated symptoms, treatments, and outlook. The lymphatic system plays an instrumental role in the body's ability to fight infections and other diseases. It comprises organs and tissues that produce, carry, and store white blood cel

Retinal problems: Types, symptoms, and treatments - Medical News Today

Image
The retina is the innermost layer of the eye, and it features many light-sensitive photoreceptor cells. These cells detect light and convert it into electrical signals, which travel through the optic nerve to the brain, resulting in sight. Retinal disorders affect the retina and typically result in visual problems. The human eye is a specialized organ that reacts to light and allows people to see. The eye has many structures that enable vision, including the retina. Retinal disorders are conditions that affect any part of the retina. Some can mildly affect a person's vision, while others may lead to blindness. However, it may be possible to prevent most retinal disorders if an eye doctor identifies the condition early and provides appropriate treatment. If a person is experiencing problems with their retina, they may need to see an ophthalmologist. This is a medical professional who specializes in ophthalmology, or eye care. In particular, a person may need to visit an eye doctor w

What Do Color-Blind People See? - Verywell Health

Image
Color blindness, also known as color vision deficiency, is a condition where someone cannot see colors normally in both eyes. It represents a group of conditions that affect color perception, including red-green color blindness, blue-yellow color blindness, and blue cone monochromacy. Red-green color vision defects, the most common form of color vision deficiency, occurs in about one in 12 males and one in 200 females among people of Northern European ancestry.   Roman Donar / Getty Images Definition The retina in your eye is in charge of detecting color.   The retina is made up of two photoreceptor cells known as rods and cones. While rods detect brightness and darkness, cones detect color. There are three types of color cone cells: red, green, and blue. The brain uses input from these cone cells to determine our color perception. Color blindness occurs when one or more of the color cone cells are absent, not

As pink eye cases expected to rise this winter, experts say it’s not a common symptom of COVID - masslive.com

As winter approaches, conjunctivitis, a common, irritating eye ailment, will become more common. "Conjunctivitis is an unpleasant eye condition that is a very common health issue among both kids and adults," Dr. Vincent Meoli, regional medical director of American Family Care said in a press release. "Pink eye is inflammation of the conjunctiva, which is the tissue that lines the eyelid and covers the white part of the eye. The condition is commonly caused by viruses, bacteria and allergens, but other irritants can cause pink eye as well." A common symptom of the ailment, where it also got its name, is red or pink color in the white part of one or both eyes. Other symptoms include itching, irritation, discharge of pus or mucus, crusting of eyelids or eyelashes, watery eyes and a feeling like something is in the eye, according to the release. Pink eye is not often serious, but vision can be affected if it's not treated promptly. "Some of the viruses and bact

How to Get Rid of a Male Yeast Infection Fast - Verywell Health

Image
Yeast infections, though commonly associated with women, can happen in men too. Most male yeast infections occur on the penis, but they can also extend to the groin. The most common cause of yeast infection in a male is the fungus Candida. There are over 150 species of Candida , with Candida albicans being the most common cause of infections. Both men and women have small amounts of Candida naturally present on their bodies. Problems occur when the yeast multiply and overgrow in certain parts of the body.  Having condomless sex with a partner who has a yeast infection, poor personal hygiene, excess moisture in the groin, and medical problems like diabetes can contribute to an overgrowth of  Candida  in men, causing redness and itchiness on the penis. When the inflammation and infection are on the head of the penis, it is called balanitis. Thankfully, most male yeast infections can be treated with over-the-counter antifun

What to consider with severe or persistent diaper rash - Contemporary Pediatrics

Image
Moderate to severe diaper dermatitis affects nearly 9% of infants in the first year of their life. 1 Commonly known as diaper rash, these reactions are typically caused by some type of contact irritant, but there are a number of differential diagnoses that could also increase the severity of these rashes. 2 Bernard A. Cohen, MD, a professor of pediatric dermatology at the Johns Hopkins School of Medicine and director of the Johns Hopkins University Pediatric Dermatology and Cutaneous Laser Center, in Baltimore, Maryland, said contact dermatitis is the most common cause of diaper rash. Infants spend almost every minute of their day in diapers, and near-constant exposure to urine, stool, and general moisture can irritate the delicate skin in the perianal and genital areas. Although many cases of diaper rash can be treated simply with strict hygiene and over-the-counter barrier creams, there are some red flags that pediatricians should consider that may signal a more severe problem.

Brain implant restores 'sight' in blind person - Medical News Today

Image
Share on Pinterest An exciting new study has allowed a blind person to 'see' letters. Erik Von Weber/Getty Images A group of researchers recently attempted to use a microelectrode array to help a blind person perceive letters and shapes. The implant, which is about the size of a penny, bypasses the optic nerve and instead provides stimulation to the brain's visual cortex. By the end of the study, the participant could identify several letters. According to the Centers for Disease Control and Prevention (CDC), approximately 1 million people in the United States over the age of 40 years are blind. Although there is currently no cure for blindness, a new implantable device may one day become a useful way to increase the independence of blind people. The implant uses an electrode to provide artificial vision. Although the device is in the early stages of clinical development, the first experiment in a human participant was successful. The results now appear in The Journal of C

Goosebumps on the skin: Causes and symptoms - Medical News Today

Image
Share on Pinterest Chills and cold temperatures are among the causes of goosebumps on the skin. Goosebumps appear when the arrector pili muscles contract, pulling the hairs into an upright position. On areas of the body that do not have much hair or that only have light hair, a person might notice only the erect hair follicle and not the hair itself. Erect hair follicles look swollen and slightly bigger than usual. This enables them to hold the hair upright, and it also causes goosebumps. A number of specific factors can give rise to goosebumps. These include: Chills and cold Goosebumps play an essential role in the body's ability to regulate its temperature. Other mammals, including humans' primate ancestors, have thick hair that keeps them warm. When the hair stands up, it offers more insulation. Many people notice goosebumps when they are cold. They may also appear when someone thinks about being cold, such as when they witness a cold scene in a movie. Some people also get g

7 Causes of Tunnel Vision: Plus Symptoms, Treatment & More - Healthline

Image
Whether you're driving a car or walking into a room, your peripheral vision helps you move around safely. It lets you see things without moving your head. But some conditions can interfere with peripheral vision and lead to tunnel vision, also called tubular vision. This type of peripheral vision loss affects your 360-degree visual field. There are several possible causes of tunnel vision. Some conditions only affect the eyes, while others involve the entire body. Read on to learn why tunnel vision happens, common symptoms to watch out for, and treatment options to explore. Peripheral sight, or side vision, is what you see on the outer edges of your visual field when looking straight ahead. Tunnel vision occurs when this peripheral sight is lost. If this happens, you'll only be able to see something if you're directly looking at it. This type of vision loss is primarily caused by issues with the rods and cones — two types of photoreceptors, or light-sensing cells — in the r

Impetigo is a highly contagious bacterial skin infection that causes sores and a honey-colored crust or blister-like bumps. It can be itchy and painful, and it occurs when skin—especially already irritated or broken skin—comes in contact with a common type of staph or the bacteria responsible for strep throat. Impetigo on a child's arm. Matthew Roberge / Getty Images Types and Symptoms of Impetigo Impetigo can happen to anyone, but it typically affects infants and children and is most common in those ages 2 to 5.   Those diagnosed with impetigo are usually treated with topical antibiotics or oral antibiotics to avoid complications and prevent its spread. There are three types of impetigo that are classified based on the appearance of the infected skin and how deep the infection goes into skin layers. Though there are some common areas where impetigo begins, untreated infections can quickly spread to other areas on the child's b
