Typical UVB Narrowband Cabinet

We’ve seen a few reports out of New Zealand with respect to the use of ultraviolet light. Here’s one I added to our blog in July: < click here > 

Recently (12 October) another article was posted about the use of UVB and kids. The study involed  116 children. Here’s the essence of the article.

Background:  Phototherapy is effective for many dermatoses in adults, but there is a paucity of data for its use in children. 

Objectives:  To review the efficacy and tolerability of narrowband UVB phototherapy in children at a tertiary centre in New Zealand, and determine if there were any factors that differentiated responders from non-responders. 

Methods:  A prospective analysis of children (<16 years old) who had undergone phototherapy over a 15-year period. 

Results:  116 children received phototherapy with a total of 144 courses. Mean age was 11.0 years with the majority being European and having skin phototype II. Atopic dermatitis was the most common indication for treatment followed by psoriasis, pityriasis lichenoides, nodular prurigo, morphea, vitiligo, urticaria pigmentosa and erythropoietic porphyria. Treatment was effective in the majority of children (72%). Most received only one course. For responders, the mean number of treatments was 32.4. The mean dose per treatment to achieve clearance was 886 mJ/cm2 and the mean maximum treatment dose per treatment was 1328 mJ/cm2. All children tolerated treatment well with 36% developing brief, minimally symptomatic, erythema. Only two children experienced exacerbations of their underlying dermatoses. 

Conclusions:  This study shows that phototherapy is an effective and well-tolerated treatment modality in children. 

UVB Narrowband products for home and clicical use can be found at www.homephototherapy.com

The new Dermalume 2X uses the National Biological Corp CPT or Controlled Prescription Timer to help the doctor and the patient work together for optimal treatment.

It’s interesting to see the sales of our Dermalight 80 drop slightly as our sales of the Dermalume ramp up.

The Dermalume 2X arrives ready for use in a handy briefcase type case allowing the user to easily pack it away between treatments and carry it with them while traveling.

The unit allows the user to treat only affected areas – and use comb to maintain consistent distance from skin or separate hairs for scalp psoriasis treatment.

The clever hinge allows multiple wand positions can be held where you want while the two lamps with the large output window allow for faster treatment. The DermaLume is shipped fully assembled with an optional comb attachment (includes) , goggles, and carrying case.

You can learn more about the Dermalume 2X at our website. Please visit http://www.homephototherapy.com/dermalume2X.htm for more information.

Since the publishing of the article on May 7th by the British Medical Journal on the effectiveness of UVB Treatment in the home, the Internet has been buzzing with articles written by a host of reviewers on the subject. Most are simply referring to the original article but many are commenting. Most if not all of the postings I’ve seen on various blogs and publications show strong support for the use of UVB Narrowband Therapy in the home.

This of course is like music to my ears. Many of you know that I run a business offering UV Phototherapy Products for use in the home. See www.HomePhotoTherapy.com. So of course I’m a little biased.

The actual heading of the article is “Home versus outpatient ultraviolet B phototherapy for mild to severe psoriasis: pragmatic multicentre randomised controlled non-inferiority trial (PLUTO study)”

The finding by the researchers who followed 196 patients was “Ultraviolet B phototherapy administered at home is equally safe and equally effective, both clinically and for quality of life, as ultraviolet B phototherapy administered in an outpatient setting. Furthermore, ultraviolet B phototherapy at home resulted in a lower burden of treatment and led to greater patients’ satisfaction. “

This statement flies in the face of many dermatologists that say that they believe that treatment at home is the wrong approach because they believe that patients will not be compliant at home. It’s interesting to note that many of the derms who make such ridiculous statements have phototherapy systems in their offices or clinic and they draw some of their income for the sale of time in their own phototherapy systems. I guess it shows that even doctors like to make a dollar.

Treatment at home is ultimately much less expensive to the patient and the insurance company than in-clinic treatment. Typical home equipment can range from $600.00 to $7000.00 with most folks spending perhaps $2500.00 on a home system. In clinic rates can vary from a low of $25.00 to a high of $90.00 PER TREATMENT. I we take an average of let’s say $40.00/treatment with three treatments a week then that’s $120.00/week and in 20 weeks ($2400.00), the typical home system would be paid for. That does not include the costs of parking, car mileage, time of work.

Visit www.HomePhotoTherapy.com to see some home systems. Remember most folks over a lifetime require treatment sometimes several times a year, perhaps for a lifetime.

The absolute best way to have UV Treatment is in the home.

OK, so what’s a dosimeter you ask? UV Phototherapy systems in clinicasl use (in a clinic, hospital or doctor’s office) absolutely require some form of dosimetry. A dosimeter is a device that measures the power of the UV light output from the lamps and determines the treatment time required for that particular treatment session based on the input from the clinician.

In home use, a dosimeter can add significant cost to a phototherapy system and offer no advantage to the home user. In a clinical environment, lamps age, patients might not be using the same phototherapy booth or panel or might go to a different clinic. For these reasons it is important that the treatment dosage, usually measured in Joules or Milli-Joules is known and recorded. Then, if the patient returns to a unit where bulbs have been replaced or perhaps a different booth the last treatment energy in Joules or Milli-Joules is known and can be used to set the dosage for the next treatment.

In the home, the user uses the same machine every day and unless new lamps are installed the power output from the lamps will be essentially the same as the output two days earlier during the prior treatment and the treatment time will usually be the same. Please see my posting on treatment times for the home user <CLICK HERE> 

A Joule is a measurement of ENERGY which is POWER delivered over time. OK so now it’s getting more complicated and for that I apologize. I have created a page called “Joules,

The spectrum of light is broken up into several pieces such as UV (ultraviolet), IR (infrared) and of course visible light. UV and IR are not visible to the naked eye but each affects our skin and in the case of IR can be felt as heat on the human skin. UV light is not seen or felt but it can have profound and lasting effects on the skin in beneficial and sometimes harmful ways.

Looking at the image above, one should notice that

1) The red line is our skin’s sensitivity to UV light
2) The blue line is what we call UVB Broad Band
3) The green line is UVB Narrow Band
