Point to the Index: The UV Index

The National Weather Service (NWS) and the Environmental Protection Agency (EPA) developed the Ultraviolet (UV) Index in 1994. The UV Index is a useful tool to help the public take steps towards reducing UV radiation exposure, since skin cancer and other skin diseases have increased significantly in the US since 1975.

The UV Index tells us the level of UV exposure expected on a given day. The categories are: low, moderate, high, very high, and extreme with corresponding index numbers 1-2, 3-5, 6-7, 8-10, 11+. The UV Index reminds people to protect themselves when engaging in outdoor activities.

The EPA encourages consumers to practice the following sun protection steps:

  • Check the UV Index for the UV forecast.
  • Limit exposure during midday hours.
  • Seek shade.
  • Wear clothing made from tightly woven fabrics. UV rays can pass through holes and spaces in loosely knit fabric. Long-sleeved shirts and pants are recommended.
  • Wear a hat with a wide brim that protects the eyes, face, and neck.
  • Wear sunglasses that provide 100% UV protection.
  • Use broad spectrum sunscreens with at least Sun Protection Factor (SPF) 15 and reapply regularly. Remember to apply sunscreen on any part of the skin that is exposed to the sun, such as the nose, the back of the neck, and the rims of the ears. Use lip balms or creams containing sunscreen.

Here’s the chart straight from the EPA:

So, you might be wondering how is the Index calculated?

In a nutshell, it begins with forecasting the total ozone amount by using NWS models. Then, the sun angle for that specific day is determined. Next, a radiation model determines different UV radiation wavelengths, which are then weighed into human skin. Lastly, outside factors such as location, sea level and cloud conditions are measured and adjusted to the index.

The UV Index is a great tool to educate yourself on how intense each day’s sun exposure will be. The sun can be extremely harmful, as most of us know, causing anything from wrinkles, to eye damage, to skin cancer. It’s great to have this kind of knowledge in order to prevent these things from happening to you.

Birthmarks – How to Tell Your Twins Apart

twins-birthmarks-dermatology2

Birthmarks are persistent areas of discolored skin that are generally visible from birth. While many birthmarks are permanent, some fade with time.  In general, birthmarks arise from either a concentration (or lack) of pigmentation or from a concentration of blood vessels in or just below the skin.

Strawberry Mark

A Hemangioma is a bright red raised area that can occur anywhere in the skin.   It might be barely noticeable at birth and then grow to an inch or several inches across during a child’s first months.  Because a hemangioma brings a blood supply to the surface of the skin, they may bleed easily if bumped or scratched.

Often when the child is 6 to 12 months old, the redness will fade to gray and the mark will flatten and fade in a process know as involution.  In some cases the skin might break down and erode during involution.   Strawberry marks often disappear by the time the child is 5 years old.  Strawberry marks on the scalp are often hidden by hair and require no treatment.  A hemangioma near an eye or on the face is often treated more aggressively.  Read more about Hemangiomas and Strawberry Marks here.

There are two main types of hemangiomas:

  • Strawberry hemangiomas (strawberry mark, nevus vascularis, capillary hemangioma, hemangioma simplex) may develop several weeks after birth.
  • Cavernous hemangiomas (angioma cavernosum, cavernoma) are similar to strawberry hemangiomas but they are deeper.

Port Wine Stains

A port wine stain is a hemangioma of dilated capilaries, and generally presents as a large red or purplish spot that occurs on the arm, leg or face.   It is sometimes raised and generally persists throughout adulthood.  Some port wine stains are associated with Sturge-Weber syndrome, so check with your pediatrician.    Port Wine stains often respond well to laser treatment which can soften the discoloration and provide cosmetic benefits.

Mongolian Spots

Mongolian spots are flat marks of various sizes that are present at birth and resemble bruises on the lower back or buttocks.  The spots are bluish greay to bluish green.

Cafe au lait spots

Cafe au lait spots are flat, irregularly shaped small tan or brown areas present on the skin at birth.

Capillary Marks

Capillary marks are small pinkish brown or pink spots present at birth that gradually fade away before a child is 18 months old.

Acne – Triggered Suicide

teen suicide due to acne

Acne isn’t “just” a skin problem. In this BBC article, teens can suffer suicidal depression due to low self-esteem. Some of the acne treatments can exacerbate the mood swings resulting in self-destructive behavior.

Depressed about her teenage acne, Melissa Hewett started to self-harm and tried almost monthly to take her own life.

The acne, which covered much of her body, left her feeling worthless and miserable.

She spent time in a mental health clinic getting treatment for her depression.

Now Melissa’s acne has cleared and, at the age of 21, she is starting to live again and is engaged – but she feels acne robbed her of much of her youth.

Self-harming

This summer Melissa is taking part in the British Skin Foundation’s ‘Walk for Skin’ to promote the desperate need for research and funding into acne and its effects.

Indy Rihal, from the foundation, feels the funds are urgently needed.

“Millions of people suffer from skin disease in the UK and more needs to be done to help,” she said.

“The “Walk for Skin” raises money for vital research into all skin diseases, including acne.

“We can make a real difference to those people whose lives are blighted by skin disease and help to fund research into new treatments and eventually cures.”

Melissa is proof of the impact the skin condition can have on young people.

Not only did she struggle to deal with the condition, but her misery was compounded by others simply dismissing it as routine “teenage spots”.

“Having acne was horrible,” said Melissa, an events organiser from Berkshire.

“I developed at a young age, which meant my acne started young at about 11 to 12 years old.

“My back, neck and face were covered in spots. My back was hit worst, so I would always wear a shirt over strappy tops or high-backed tops.”

Melissa was bullied at school and started to cut herself.

“I needed to release pain that was built up, I blamed my skin for causing the problems, so I took it out on my skin,” she said.

“I felt it didn’t matter, as who would ever look at me anyway, except to mock me?”

Taking acne seriously

Melissa tried everything to try to clear her skin, from over-the-counter remedies to prescription drugs, like roaccutane, made by pharmaceutical company Roche.

She was placed on the drug at 13 and she says she feels that combined with anti-depressants, which she was also taking, it triggered her slide from feeling miserable about her acne into a clinical depression.

“I was feeling low because of the acne, but will always think that the anti-depressants and roaccutane triggered me into an actual depression,” she said.

“I felt suicidal, I self-harmed and began not just to feel ugly, but to hate myself.

“I felt worthless, that I wasn’t a good enough human. The treatment did help my skin though.

“But I started to cut myself and attempted suicide every month.

“Once the acne had gone I still found it very difficult to like myself as I had all the scars still from cutting.

“It took a few years and my wonderful fiancé to bring me back up from a very dark place.”

Melissa, who is currently not taking medication, said acne needs to be taken more seriously.

Devastating effects

Dr Alison Layton, consultant dermatologist for the British Skin Foundation, agreed that acne – even quite mild acne – can have devastating affects on self esteem.

Acne facts

  • Acne is the most common inflammatory skin disease in the world
  • It affects between 80-85% of all adolescents. It usually peaks at age 15
  • In 12% of cases acne continues into adulthood – most of these are women

teen suicide due to acne“Although there is a spectrum and you can get very mild and very severe acne, the psychological impact can be quite immense even with quite minimal problems,” she said.

“I think that the reason for that is that it hits young people at a time when they are undergoing the maximum change and wanting to look good.

“People with quite mild acne can get quite depressed by it and yet you can see people with quite severe acne cope quite well.

“The bottom line is that it has the potential to cause problems psychologically.

“The depression can be quite severe, causing suicide, and people can be very clinically depressed.”

Medicines and Healthcare products Regulatory Agency statistics show 27 young people have committed suicide in Britain while taking roaccutane, although there is no proof that the drug is the cause.

A spokesman for Roche said: “Unfortunately, severe acne can cause some sufferers to become depressed and can also affect their mood and self esteem.

“This is why the information provided with roaccutane (isotretinoin) carries a warning that some patients may experience mood changes, including an increase in depression.”

He added that over the past 20 years, more than 13 million people worldwide have been treated for severe acne using roaccutane.

While no causal link had been established between the drug and either depression or suicide, it was constantly monitored.
