Pre-eclampsia : What it is, whose at risk for it, causes,symptoms, when to go to MD, complications and prevention!

The Box below shows the organs Pre-eclampsia can effect:

What is Preeclampsia?

Preeclampsia is a condition that occurs only during pregnancy. Some symptoms may include high blood pressure and protein in the urine, occurring after week 20 of pregnancy. Preeclampsia is often precluded by gestational hypertension. While high blood pressure during pregnancy does not necessarily indicate preeclampsia, it may be a sign of another problem. The condition affects at least 5-8% of pregnancies.

Preeclampsia, formerly called toxemia, is when a pregnant woman has high blood pressure, protein in her urine, and swelling in her legs, feet, and hands. It can range from mild to severe. It usually happens late in pregnancy, though it can come earlier or just after delivery.

Preeclampsia can lead to eclampsia, a serious condition that can have health risks for mom and baby and, in rare cases, cause death. Women with preeclampsia who have seizures have eclampsia.

If you have a mild case and your baby has not reached full development, your doctor will probably recommend you do the following:

  • Rest, lying on your left side to take the weight of the baby off your major blood vessels.
  • Increase prenatal checkups.
  • Consume less salt
  • Drink at least 8 glasses of water a day
  • Change your diet to include more protein

If you have a severe case, your doctor may try to treat you with blood pressure medication until you are far enough along to deliver safely, along with possibly bed rest, dietary changes, and supplements.

The only cure for preeclampsia is to give birth. Even after delivery, symptoms of preeclampsia can last 1 to 6 weeks or more.

You can help protect yourself by learning the symptoms of preeclampsia and by seeing your doctor for regular prenatal care. Catching preeclampsia early may lower the chances of long-term problems for both mom and baby.

For many years preeclampsia has been considered to be a two-stage disease. The first stage comprises poor placentation. The second stage is the clinical expression of the disease namely new hypertension and new proteinuria in the patient.

Who is at risk for preeclampsia?

  • A first-time mom
  • Previous experience with gestational hypertension or preeclampsia
  • Women whose sisters and mothers who had preeclampsia (family history)
  • Women carrying multiple babies
  • Women younger than 20 years and older than age 35
  • Women who had high blood pressure or kidney disease prior to pregnancy
  • Women who are obese or have a BMI of 30 or greater
  • Complications in previous pregnancy.

Preeclampsia Causes

Many experts think preeclampsia and eclampsia happen when a woman’s placenta doesn’t work the way it should, but they don’t know exactly why. Some think poor nutrition or high body fat might contribute. A lack of blood flow to the uterus could play a role. Genes are also a factor.

How do I know if I have preeclampsia?

At each prenatal checkup, your healthcare provider will check your blood pressure, urine levels, and may order blood tests which may show if you have preeclampsia. Your physician may also perform other tests that include: checking kidney and blood-clotting functions; ultrasound scan to check your baby’s growth; and Doppler scan to measure the efficiency of blood flow to the placenta.

Symptoms:

Preeclampsia sometimes develops without any symptoms. High blood pressure may develop slowly, or it may have a sudden onset. Monitoring your blood pressure is an important part of prenatal care because the first sign of preeclampsia is commonly a rise in blood pressure. Blood pressure that exceeds 140/90 millimeters of mercury (mm Hg) or greater — documented on two occasions, at least four hours apart — is abnormal.

Other signs and symptoms of preeclampsia may include:

  • Excess protein in your urine (proteinuria) or additional signs of kidney problems
  • Severe headaches
  • Changes in vision, including temporary loss of vision, blurred vision or light sensitivity
  • Upper abdominal pain, usually under your ribs on the right side
  • Nausea or vomiting
  • Decreased urine output
  • Decreased levels of platelets in your blood (thrombocytopenia)
  • Impaired liver function
  • Shortness of breath, caused by fluid in your lungs

When to go to the doctor:

Make sure you attend your prenatal visits so that your health care provider can monitor your blood pressure. Contact your provider immediately or go to an emergency room if you have severe headaches, blurred vision or other visual disturbances, severe belly pain, or severe shortness of breath.

Because headaches, nausea, and aches and pains are common pregnancy complaints, it’s difficult to know when new symptoms are simply part of being pregnant and when they may indicate a serious problem — especially if it’s your first pregnancy. If you’re concerned about your symptoms, contact your doctor.

Complications may include:

  • Fetal growth restriction. Preeclampsia affects the arteries carrying blood to the placenta. If the placenta doesn’t get enough blood, the baby may receive inadequate blood and oxygen and fewer nutrients. This can lead to slow growth known as fetal growth restriction.
  • Preterm birth. Preeclampsia may lead to an unplanned preterm birth — delivery before 37 weeks. Also, planned preterm birth is a primary treatment for preeclampsia. A baby born prematurely has increased risk of breathing and feeding difficulties, vision or hearing problems, developmental delays, and cerebral palsy. Treatments before preterm delivery may decrease some risks.
  • Placental abruption. Preeclampsia increases your risk of placental abruption. With this condition, the placenta separates from the inner wall of the uterus before delivery. Severe abruption can cause heavy bleeding, which can be life-threatening for both the mother and baby.
  • hemolysis elevated liver enzymes and low platelet count (HELLP) syndrome. HELLP stands for hemolysis (the destruction of red blood cells), elevated liver enzymes and low platelet count. This severe form of preeclampsia affects several organ systems. HELLP syndrome is life-threatening to the mother and baby, and it may cause lifelong health problems for the mother.Signs and symptoms include nausea and vomiting, headache, upper right belly pain, and a general feeling of illness or being unwell. Sometimes, it develops suddenly, even before high blood pressure is detected. It also may develop without any symptoms.
  • Eclampsia. Eclampsia is the onset of seizures or coma with signs or symptoms of preeclampsia. It is very difficult to predict whether a patient with preeclampsia will develop eclampsia. Eclampsia can happen without any previously observed signs or symptoms of preeclampsia.Signs and symptoms that may appear before seizures include severe headaches, vision problems, mental confusion or altered behaviors. But, there are often no symptoms or warning signs. Eclampsia may occur before, during or after delivery.
  • Other organ damage. Preeclampsia may result in damage to the kidneys, liver, lung, heart, or eyes, and may cause a stroke or other brain injury. The amount of injury to other organs depends on how severe the preeclampsia is.
  • Cardiovascular disease. Having preeclampsia may increase your risk of future heart and blood vessel (cardiovascular) disease. The risk is even greater if you’ve had preeclampsia more than once or you’ve had a preterm delivery.

Prevention of preeclampsia:

Medication

The best clinical evidence for prevention of preeclampsia is the use of low-dose aspirin. Your primary care provider may recommend taking an 81-milligram aspirin tablet daily after 12 weeks of pregnancy if you have one high-risk factor for preeclampsia or more than one moderate-risk factor.

It’s important that you talk with your provider before taking any medications, vitamins or supplements to make sure it’s safe for you.

Lifestyle and healthy choices

Before you become pregnant, especially if you’ve had preeclampsia before, it’s a good idea to be as healthy as you can be. Talk to your provider about managing any conditions that increase the risk of preeclampsia.

 

 

QUOTE FOR THE WEEKEND:

July is recognized as Cord Blood Awareness Month. This month aims to educate people about cord blood donation and storage benefits. Cord blood is the blood that remains in the umbilical cord and placenta after a baby is born.

Public cord blood banking is free and will provide life-saving benefits to a family in need. Once you donate your cord blood, however, you no longer have rights to those stem cells. If your child or family member is in need of cord blood stem cells, there is no guarantee that you or children can use their own cells. With private cord blood banking, there are fees but you own the cells. Your full rights to use it are preserved, and it is always immediately available to you.”

New England Cord Blood Bank – NECBB (https://www.cordbloodbank.com/july-cord-blood-awareness-month/)

Cord Blood Awareness Month

July is National Cord Blood Awareness Month, and it’s the perfect time to learn more about cord blood—a biological product regulated by the Food and Drug Administration. Found in the blood vessels of the placenta and the umbilical cord, cord blood is collected after a baby is born and after the umbilical cord is cut—an important point.

“Because cord blood is typically collected after the baby is delivered and the cord is cut, the procedure is generally safe for the mother and baby,” explains Keith Wonnacott, Ph.D., Chief of the Cellular Therapies Branch in FDA’s Office of Cellular, Tissue, and Gene Therapies.

Approved Uses By the Food and Drug Administration states the following:

Cord blood is approved only for use in “hematopoietic stem cell transplantation” procedures, which are done in patients with disorders affecting the hematopoietic (blood forming) system. Cord blood contains blood-forming stem cells that can be used in the treatment of patients with blood cancers such as leukemias and lymphomas, as well as certain disorders of the blood and immune systems, such as sickle cell disease and Wiskott-Aldrich syndrome.

“Cord blood is useful because it is a source of stem cells that form into blood cells. Cord blood can be used for transplantation in people who need regeneration, that is, ‘regrowth,’ of these blood-forming cells,” Wonnacott says.

For instance, in many cancer patients, the disease is found in the blood cells. Chemotherapy treatment of these patients kills both cancer cells and the healthy blood-forming stem cells. Transplanted stem cells from cord blood can help regrow the healthy blood cells after the chemotherapy.

However, cord blood is not a cure-all.

“Because cord blood contains stem cells, there have been stem cell fraud cases related to cord blood,” says Wonnacott. “Consumers may think that stem cells can cure any disease, but science doesn’t show this to be the case. Patients should be skeptical if cord blood is being promoted for uses other than blood stem cell regeneration.”

About Cord Blood Banking

After cord blood is collected, it is frozen and can be safely stored for many years. “The method of freezing, called ‘cryopreservation,’ is very important to maintain the integrity of the cells,” Wonnacott says. “Cord blood needs to be stored carefully.”

You may choose to store your baby’s cord blood in a private bank so it can be available if needed in the future by your child or first- or second-degree relatives. Private cord banks typically charge fees for blood collection and storage.

Or you may donate the cord blood to a public bank so that doctors can use for a patient who needs a hematopoietic stem cell transplant.

FDA regulates cord blood in different ways, depending on the source, level of processing and intended use.

Cord blood stored for personal use, for use in first- or second-degree relatives, and that also meets other criteria in FDA’s regulations, does not require the agency’s approval before use. Private cord banks must still comply with other FDA requirements, including establishment registration and listing, current good tissue practice regulations, and donor screening and testing for infectious diseases (except when cord blood is used for the original donor). These FDA requirements ensure safety of these products by minimizing the risk of contamination and transmission of infectious diseases.

Cord blood stored for use by a patient unrelated to the donor meets the legal definitions of both a “drug” and a “biological product.” Cord blood in this category must meet additional requirements and be licensed under a biologics license application, or be the subject of an investigational new drug application before use. The FDA requirements help to ensure that these products are safe and effective for their intended use.

Not every cord blood unit will meet requirements for public banking, adds Safa Karandish, M.T., an FDA consumer safety officer. If that happens, some of this donated cord blood may be used for non-clinical research.

QUOTE FOR FRIDAY:

“With warmer weather finally arriving, the Wyoming Department of Health (WDH) wants residents to enjoy favorite activities while also avoiding certain illnesses often linked with summer fun.

“If not done safely, many warm weather activities can sometimes cause unpleasant stomach-related symptoms and occasionally serious illness,” says Courtney Tillman, epidemiologist with WDH.

Diseases such as cryptosporidiosis, giardiasis and shigellosis are diarrheal illnesses caused by swallowing water from pools or outdoor sources contaminated with animal or human feces. These illnesses, along with salmonellosis, campylobacteriosis and E. coli-related illnesses, can also result from direct contact with animals or their feces during animal-related activities such as brandings or petting zoos.

Matt Peterson, another WDH epidemiologist, said, “Every spring in Wyoming, we begin seeing new cases of salmonellosis linked to backyard poultry.” Most of these cases are children under 5 who have touched or held baby poultry in ranch supply stores or whose family have recently acquired baby poultry. Young children are more likely to get sick with Salmonella because their immune systems are still developing and they are more likely to put their fingers or other items with germs into their mouths.

“Do not let young children touch live poultry (including chicks and ducklings) or touch anything in the area where the birds live and roam,” Peterson cautions. “Backyard poultry can have Salmonella germs in their poop and on their bodies even when they look healthy and clean. The germs spread easily to their cages, coops, hay, plants and soil in the areas they live and roam.”

Tillman added, “You should always wash your hands after coming into contact with animals or their habitats. It’s best to clean hands with running water and soap. If you can’t immediately access running water and soap, use hand sanitizer until you’re able to wash your hands.”

“Water sources and animals may look clean, but can still be contaminated,” Tillman said.

Simple things we can do to help protect ourselves and others include:
• DO stay out of the water if sick with diarrhea.
• DO shower before getting in the water. When chlorine mixes with dirt, sweat, pee and poop, there is less chlorine available to kill germs.
• DO take kids on bathroom breaks or check diapers every hour. Change diapers away from the water to keep germs from getting in.
• DO dry ears thoroughly with a towel after getting out of the water.
• DO boil or use a filter or solution designed to remove germs from streams, rivers and lakes before drinking.
• DO wash hands thoroughly after coming into contact with animals and their habitats, before preparing food and before eating and drinking.

Actions to avoid include:
• DON’T swallow swimming water and avoid getting water in the mouth.
• DON’T poop or pee in swimming water.
• DON’T sit or stand on jets at splash pads. Sitting or standing on jets can rinse poop off butts.
• DON’T let children kiss animals or put objects in their mouths after touching animals.
• DON’T touch wild animals or their carcasses. If concerned about a wild animal or animal carcass, contact your local animal control office.

Summer Ailments!

 

We normally associate illness with winter, mainly because it’s the time of year we tend to get colds and flu.

However, there is no shortage of ailments and conditions that make life unpleasant and spoil our fun during the summer months.

The following are examples of health issues associated with summer:

1. Food poisoning

According to the CDC (Center for Disease Prevention and Control), every year around 3,000 Americans die from foodborne diseases.

Warm weather encourages bacteria to multiply, and who doesn’t enjoy barbeques and picnics during summer? Food that is prepared in advance and allowed to stand in the heat creates the perfect conditions for contamination and food poisoning.

Pre-prepared food should be handled hygienically, stored safely and kept cool if possible. It’s also better to choose foods that don’t spoil as easily or can be freshly prepared at your destination.

NHS Choices explains that most cases of food poisoning can be treated at home and do not require medical advice, and that most people will feel better in a matter of days. It is however important to replace fluids lost through vomiting and diarrhea.

If symptoms are severe, you may need to be admitted to hospital for a few days and given intravenous hydration.

2. Heat rash

Heat rash is a red or pink rash usually found on areas of the body that are covered with clothing. It happens during hot humid conditions and is most common in children. Heat rash develops when sweat ducts become blocked and swell up, looking like dots or tiny pimples on the skin. It often causes discomfort and itching.

Heat rash usually heals on its own in a matter of days and doesn’t require medical attention. In some cases the rash gets infected with symptoms like pain, swelling and pus. If this happens, be sure to see your doctor.

3. Water-borne conditions

We all like to spend time in the water during summer, and Dennis Maki, a professor of infectious diseases at the University of Wisconsin School of Medicine and Public Health, warns of the risk of bacterial infections and other water-borne illnesses as a result of taking part in recreational water activities.

Germs that turn up in swimming pool water include bacteria like E. coli, Salmonella, Camplobacter, noroviruses, and parasites. While treatment with chlorine can kill germs in swimming pools, it takes time for the chlorine to do its job.

Crypto is the most common cause of diarrhea outbreaks linked with swimming pools or water parks because it can survive up to 10 days in chlorinated water. … Infections can cause watery diarrhea, stomach cramps, nausea or vomiting, and can lead to dehydration.  CDC states “Crypto is highly resistant to chlorine, which makes it hard to kill once it’s in the water.  Swallowing just a mouthful of water with crypto in it can make otherwise healthy kids and adults sick for weeks with watery diarrhea, stomach cramps , nausea, and vomiting,” says Michele Hlavsa, chief of the CDC’s Healthy Swimming Program.  Every year, at least 15 to 20 outbreaks of diseases, like stomach bugs and diarrhea, are linked to swimming in public pools, according to the CDC.”

“Here are some tips from CDC in helping to protect you and your kids when the temperatures rise and the public pool is the only thing that will cool the heatwave:

  • Don’t swim or let your kids swim if sick with diarrhea.
  • Check the pool, hot tub, and water playground inspection scores.
  • Use test strips to check the water’s pH and chlorine levels. You can get free test kits from the website of the Water Quality & Health Council.
  • Try not to swallow the water.
  • Take small children on frequent bathroom breaks.
  • Shower before getting into a pool.
  • Listen for the sound of a working pool pump.
  • Change diapers in a diaper-changing area and away from the water.”

Apart from natural bodies of water like rivers and lakes, pools and hot tubs can also be sources of gastrointestinal problems; skin, ear and eye infections; and respiratory, neurological and viral problems. The safest places to swim are pools that are regularly checked for their chlorine levels.

4. Summer colds (summer or winter cold the symptoms are the same).

There is a kind of virus that produces cold-like symptoms, which tends to rear its ugly head during the summer months. It is called enterovirus and can cause more complicated symptoms than the typical winter cold.

Something summery may be lingering even as the season fades—the summer cold.

Colds in summertime can last for weeks, at times seemingly going away and then suddenly storming back with a vengeance, infectious-disease experts say. A winter cold, by contrast, is typically gone in a few days.

The reason for the difference: Summer colds are caused by different viruses from the ones that bring on sniffling and sneezing in the colder months. And some of the things people commonly do in the summer can prolong the illness, like being physically active and going in and out of air-conditioned buildings.

“A winter cold is nasty, brutish and short,” says Bruce Hirsch, infectious-disease specialist at North Shore University Hospital in Manhasset, N.Y. “But summer colds tend to linger. They can go on for weeks and reoccur.”

Summer colds, which can hit between June and October, occur only about 25% as often as the winter variety. But summer colds can have more severe, flu-like symptoms, in addition to sneezing and coughing. Many people also mistake a summer cold for allergies, because it just doesn’t seem to leave.

According to Merck Manual, symptoms of a summer cold caused by enterovirus include fever, headache, and sore throat, and sometimes mouth sores or a rash. Treatment is basically aimed at relieving symptoms.

5. Headache

An unfortunate result of summer activities that involve spending a lot of time in the hot sun can be a spitting headache. A survey by the National Headache Foundation indicates that headache sufferers consider summer to be the worst time of year for headaches.

As the temperature goes up, so does your risk for getting a headache. One theory is that the heat makes blood vessels in your head expand, causing them to press against nerve endings. Dehydration and strenuous exercise in hot weather can also lead to headaches.

An over-the-counter painkiller will usually alleviate headaches caused by heat exposure and exercise, and drinking enough water should take care of a dehydration headache.

6. Heat stroke

Heat stroke or hyperthermia results from prolonged exposure to high temperatures. It can happen for example when children are left in hot cars during summer.

Emedicinehealth defines heat stroke as a condition where the body’s cooling mechanisms are overcome by heat, resulting in a core heat of over 40°C. Heat stroke is preceded by signs of heat exhaustion like headaches, dizziness and weakness, and results in unconsciousness, organ failure and eventually death.

Hyperthermia is primarily treated by outside cooling of the body with the help of water, cold air or ice packs. Internal cooling by flushing the stomach or rectum with cold may also be used. Persons with hyperthermia need to be hospitalised in order to be tested for complications like muscle breakdown, which can damage the kidneys.

7. Sunburn

With summer comes the danger of sunburn, which can be extremely serious. Sunburn is caused by ultraviolet (UV) rays from the sun that damage your skin cells. The risk of damage depends on things like the time of day, the amount of time spent in the sun and if you use sun protection or not.

Sunburn can lead to long-term skin damage and even skin cancer. MedicineNet.com explains that there are three major kinds of skin cancer:

  • Basal cell carcinoma (most common type)
  • Squamous cell carcinoma (second most common)
  • Melanoma (less common but considerably more dangerous)

The best and simplest way to avoid sunburn is to stay out of the sun. Other ways to be sun-safe is to stay out of the midday sun, stay in the shade, use a good sunscreen and wear a hat and protective clothing.

 

QUOTE FOR WEDNESDAY:

“The start of summer is the perfect time to gather with family and friends for good food and fun times. This year, celebrate the adoption of the Declaration of Independence safely. Our July 4th safety tips cover a few key summer safety topics to help keep you and your family safe this Independence Day.

Fireworks cause over 19,000 fires every year. Take the proper precautions when operating fireworks.

  • Never disassemble or try to make your own fireworks.
  • Don’t point sparklers, or fireworks at yourself or others, especially when lighting them.
  • Only light fireworks on the ground and in areas that are dry and fire-resistant.
  • Don’t attempt to ignite fireworks at the same time.
  • Never allow young children to handle fireworks or sparklers to prevent firework-related injuries.
  • Always keep a portable fire extinguisher close by. Also, keep a water hose or buckets of water nearby to put out fires.
  • If fireworks malfunction, don’t relight them! Douse and soak malfunctioning fireworks with water then throw them away.
  • Resist the urge to bring your dog to a fireworks display. The safest place for them is at home where it’s familiar, quiet and not crowded.

Never allow young children to handle fireworks or sparklers to prevent firework-related injuries. Sparklers are hot enough to cause severe burns if mishandled.”

ADT (https://www.adt.com/resources/4th-of-july-safety-tips)

Being safe in general the 4th of July this week and even if extends into the weekend!

This 4th of July there is safety in general whether at home or going out.

Regarding in the water:

As July is one of the hottest months of the year, many families turn to water activities to beat the heat. However, even fun water activities have serious risks if the proper precautions aren’t taken.

  • Review safe boating practices.
  • Never consume alcohol while driving a boat.
  • Before boating, always check that there are enough life preservers on hand for every passenger.
  • Set water safety rules for your family, especially if there’s a young child.
  • Keep a first aid kit near the pool.
  • Pool Security-Many people don’t consider the security of their hot tub or pool, but to keep your guests and family members safe, you need more than just constant supervision. This is why an outdoor home camera system is one great way to ensure that everyone keeps having fun and stays safe but better than that is always an adult taking the safeguard job watching the children.  The parents or responsible adult can take alternate doing this job and without question be able to swim and preferably BCLS certified or someone at the gathering BCLS certified or even a doctor or nurse at the party is helpful.The CDC states that about 10 people per day die from unintentional drowning in the United States. Having cameras specifically for your outdoor pool area can help to provide a much safer space against the common causes of pool accidents. Since you are able to access your cameras from any smart phone, you will always be in the loop. While no amount of home security cameras can compensate for parental supervision when it comes to your young ones going for a swim, it is a great addition to help provide additional security.

July is one of the peak months for grilling fires. Enjoy grilling your favorite meals this summer while also keeping your family safe.

Regarding Grilling, this weekend and everytime you grill for safety always:

  • Check gas grill hoses for cracks, holes and leaks.  To do this take soapy water and put it over the connection tube to the tank & if bubbles, Your Leaking.
  • Keep children away from grills. Gas leaks, blocked tubes, and propane tanks can be a cause of grill fires and explosions.
  • Never grill indoors, in the garage, in any enclosed area or on a surface that might catch fire.  Grill always outdoors.
  • Keep the grill at least two feet away from decks, siding, branches and any outdoor equipment that can catch fire quickly.

More than 50,000 fires are caused by fireworks every year but now the news is saying we will have potential for the highest amount of people on the road to get where they want to celebrate the 4th of July this year due to lock up last year; so many will be going out to celebrate but know these tips if going out or even staying home.

Regarding proper precautions when operating fireworks:

  • Never disassemble or try to make your own fireworks.

  • Don’t point sparklers, or fireworks at yourself or others, especially while they’re being lit.

  • Only light fireworks on the ground and in areas that are dry and fire-resistant.

  • Don’t attempt to ignite fireworks at the same time.

  • Never allow young children to handle fireworks or sparklers to prevent firework-related injuries.

  • Always keep a portable fire extinguisher close by. Also, keep a water hose or buckets of water nearby to put out fires.

  • If fireworks malfunction, don’t relight them! Douse and soak malfunctioning fireworks with water then throw them away.

Regarding your Pets:

  • Resist the urge to bring your dog to a fireworks display. The safest place for them is at home where it’s familiar, quiet and not crowded.

QUOTE FOR TUESDAY:

“The strength of the sun’s UV rays reaching the ground depends on a number of factors, such as:

  • Time of day: UV rays are strongest in the middle of the day, between 10 am and 4 pm.
  • Season of the year: UV rays are stronger during spring and summer months. This is less of a factor near the equator.
  • Distance from the equator (latitude): UV exposure goes down as you get further from the equator.
  • Altitude: More UV rays reach the ground at higher elevations.
  • Cloud cover: The effect of clouds can vary, but it’s important to know that UV rays can get through to the ground, even on a cloudy day.
  • Reflection off surfaces: UV rays can bounce off surfaces like water, sand, snow, or pavement, leading to an increase in UV exposure.”

Part II July UV Safety Month. Prevent Sunburn and Types of Photosensitivity!

The three types of Ultra Violet radiation are classified according to their wavelength.

They differ in their biological activity and the extent to which they can penetrate the skin. The shorter the wavelength, the more harmful the UV radiation. However, shorter wavelength UV radiation is less able to penetrate the skin.

The Ultra Violet region covers the wavelength range 100-400 nm and is divided into three bands:

  • UVA (315-400 nm)
  • UVB (280-315 nm)
  • UVC (100-280 nm).

Short-wavelength UVC is the most damaging type of UV radiation. However, it is completely filtered by the atmosphere and does not reach the earth’s surface.

Medium-wavelength UVB is very biologically active but cannot penetrate beyond the superficial skin layers. It is responsible for delayed tanning and burning; in addition to these short-term effects it enhances skin ageing and significantly promotes the development of skin cancer. Most solar UVB is filtered by the atmosphere.

The relatively long-wavelength UVA accounts for approximately 95 per cent of the UV radiation reaching the Earth’s surface. It can penetrate into the deeper layers of the skin and is responsible for the immediate tanning effect. Furthermore, it also contributes to skin ageing and wrinkling. For a long time it was thought that UVA could not cause any lasting damage. Recent studies strongly suggest that it may also enhance the development of skin cancers.

Treatment: One is prevention and avoid sun light when it is out the strongest in ultra-violet rays 12pm to 3pm and always use sunscreen.

Polymorphic light eruption (PLE) is the most common form of immunologically mediated photosensitivity dermatoses. Exposure to sunlight in spring or summer results in an irritable rash that resolves within a few days, providing further exposure is avoided.

The following treatments may reduce the severity of PLE:

  • Topical corticosteroid creams to relieve symptoms
  • Short course of oral steroids, eg to cover a summer holiday
  • Hydroxychloroquine
  • Phototherapy: UVB narrowband UVB, or PUVA for several weeks in early spring.

Are there any other health issues related to UV radiation?

In addition to cancer, exposure to UV rays can cause other health problems. UV rays, either from the sun or from artificial sources like tanning beds, can cause sunburn. In some people, exposure to UV rays can cause a rash or a type of allergic reaction. Exposure to UV rays can also cause premature aging of the skin and signs of sun damage such as liver spots, actinic keratosis, and solar elastosis.

UV rays can also cause eye problems. They can cause the cornea (on the front of the eye) to become inflamed or burned. They can also lead to the formation of cataracts (clouding of the lens of the eye) and pterygium (tissue growth on the surface of the eye), both of which can impair vision.

Exposure to UV rays can also weaken the immune system, so that the body has a harder time fending off infections. This can lead to problems such as reactivation of herpes triggered by exposure to the sun or other sources of UV rays. It can also cause vaccines to be less effective.

Some medications can make you more sensitive to UV radiation, making you more likely to get sunburned. Certain medical conditions can be made worse by UV radiation.

About UV rays and vitamin D

Doctors are learning that vitamin D has many health benefits. It might even help lower the risk for some cancers. Your skin makes vitamin D naturally when it is exposed to UV rays from the sun. How much vitamin D you make depends on many things, including how old you are, how dark your skin is, and how strong the sunlight is where you live.

At this time, doctors aren’t sure what the optimal level of vitamin D is. A lot of research is being done in this area. Whenever possible, it’s better to get vitamin D from your diet or vitamin supplements rather than from exposure to UV rays because dietary sources and vitamin supplements do not increase skin cancer risk, and are typically more reliable ways to get the amount you need.

Remember tips about UV rays for men and women:

Men, especially those with lighter skin, are more likely than anybody else to get skin cancer, including melanoma—the deadliest kind of skin cancer.

When you think about sun protection, you might think about a day at the beach. But over your lifetime, you get sun exposure doing everyday things like biking, working, running, or even mowing the lawn. Sun exposure is the main source of ultraviolet (UV) rays, which can cause skin cancer. And UV exposure adds up over time, increasing your risk of developing skin cancer.

Men tend to get more sun exposure than women. Men spend more time outside over their lifetimes than women, and they’re more likely to work outdoors than women. Women’s personal care products, like moisturizer and makeup, often contain sunscreen, while many products for men don’t.

About one-third of U.S. adults get sunburned each year. Sunburn, which can increase your risk of getting skin cancer, is common among white men, young adults, and men who tan indoors. When outside on a sunny day for more than an hour, only about 14% of men use sunscreen on both their face and other exposed skin.

Seek shade, especially during midday hours. This includes 10 am to 4 pm, March through October, and 9 am to 3 pm, November through February. Umbrellas, trees, or other shelters can provide relief from the sun.

Wear a long-sleeved shirt and pants or a long skirt for additional protection when possible. If that’s not practical, try wearing a T-shirt or a beach cover-up.
