Campbell 2012: Skin cancer education among MTs (#27/31)

I can't really say much about the article itself until I get to the University later this week, and can get behind the paywall, but the abstract certainly served its purpose--it alerted me that this is a potentially interesting and very useful article, and that I should go to the effort to get the entire article and read it.

Campbell SM, Louie-Gao Q, Hession ML, Bailey E, Geller AC, Cummins D. Skin Cancer Education among Massage Therapists: A Survey at the 2010 Meeting of the American Massage Therapy Association. J Cancer Educ. 2012 Aug 23. [Epub ahead of print] PMID: 22915212

Massage therapists encounter skin on a daily basis and have a unique opportunity to recognize potential skin cancers. The purpose of this study was to describe the skin cancer education provided to massage therapists and to assess their comfort regarding identification and communication of suspicious lesions. An observational retrospective survey study was conducted at the 2010 American Massage Therapy Association Meeting. Sixty percent reported receiving skin cancer education during and 25% reported receiving skin cancer education after training. Massage therapists who examine their own skin are more likely to be comfortable with recognizing a suspicious lesion and are more likely to examine their client's skin. Greater number of clients treated per year and greater frequency of client skin examinations were predictors of increased comfort level with recognizing a suspicious lesion. Massage therapists are more comfortable discussing than identifying a potential skin cancer. Massage therapists may be able to serve an important role in the early detection of skin cancer.

 

Once again, we have an invitation to up our game, to commit to the shared body of knowledge of the client-centered healthcare team, and to contribute in a specific way to that team and to the client's well-being.

What are some concrete steps we could take--individually, through our organizations, both ways, or some other way--that would demonstrate that we are serious about wanting massage to become a healthcare profession, and to take steps toward accepting that invitation?

Is this something that we really want to do? What are the risks and benefits of doing so?

The images above show the 3 classic types of skin cancer. Reading from left to right, what are the names of the skin cancers in the photographs?

Reading from left to right, do the types of cancer you see in the images get more common or less common in occurrence in the general larger population?

Reading from left to right, do the types of cancer you see in the images get more deadly or less deadly?

If you saw a skin lesion on a client during a session, and the lesion looked exactly like one of the types of cancer you see in the images, what words would you choose to talk to the client about what you saw?

 

 

Another MT saves a client's life: Davies 2003-- Syphilis referred from complementary medicine therapy (#20/31)

We're all clear (I hope) on the principle that MTs--at least in the US--do not diagnose or prescribe. It would be a massive overreach to do so, and we'd deserve the smackdown that would result if we got caught doing it.

It would never be right for us to inform someone that they have a particular disease, nor to prescribe to them what they should do about any condition they have.

But we do observe during a session, and as a result, we sometimes see things that need to have prompt action taken, in order to protect the client from harm.

So we need to be skillful about reporting what we observe to the client--we may need to balance the urgency of making it clear to the client how serious it is to follow up, versus not diagnosis, prescribing, or unnecessarily frightening them.

There are many anecdotal cases of MTs telling clients that they should get a suspicious skin lesion checked out. When the diagnosis turns out to be melanoma, which--if it remained undetected--would very likely disfigure and then kill them, then the MT rightly gets the credit for saving the client's life.

Melanoma accounts for only 4% of all skin cancers; however, it causes the greatest number of skin cancer–related deaths worldwide. Early detection of thin cutaneous melanoma is the best means of reducing mortality.--Medscape, "Cutaneous Melanoma" accessed 20 August 2012

 

Sometimes, that early detection that is the best means of reducing mortality (the death rate) comes from an MT who observes something, and tells the client "I think you ought to get that checked out with your primary healthcare provider.".

This case report is similar, yet the lesion the MT observed and recommended follow-up for to the client came from a very different condition.

 

 

 

 


Syphilis is a horrible way to die.

The man in this picture was born with ("congenital") syphilis, and you can see, even in a painting, how disfigured his face is from the disease.

The bacteria that cause syphilis, Trepomena pallidum, are spirochetes--spiral-shaped--as you can see in this electron micrograph from Wikipedia, and are spread mainly by direct sexual contact, and also from mother to child at birth:

Source: http://upload.wikimedia.org/wikipedia/commons/2/29/Treponema_pallidum.jpg accessed 20 August 2012

 

Although syphilis is referred to as "protean" (versatile, flexible, changeable) in the article we're about to review, because it can take so many forms, there is a typical presentation that's considered classic of the disease:

  • Stage I--Primary syphilis: A chancre (painless sore). Usually occurs about 3 weeks after initial exposure to infection.
  • Stage II--Secondary syphilis: Widespread rash, often involving hands and feet, possibly including other symptoms of infection such as fever, headache, weight loss. Usually occurs about 4-10 weeks after Stage I.
  • Stage III--Latent syphilis: Asymptomatic. Usually occurs around a year after initial infection.
  • Stage IV--Tertiary syphilis: Ulcerated lesions, neurological symptoms (loss of balance, apathy, seizures, dementia), cardiac symptoms (inflammation of aorta, aneurysms). Usually occurs anywhere from 3 to 45 years after initial infection.

 

The disease has been recorded in art and literature in Europe since about the 1500s. That fact, and the discovery of thousand-year-old tombs in Peru, where mummies and bones showed signs of the disease, reinforce the hypothesis that the disease originated in the New World, and was brought back to Europe by the crews of explorers and conquerors.

Syphilis goes back in recorded history for centuries--most of that time without effective treatment--and devastated people of all classes and walks of life. Those facts, along with the intimate linkage of the disease with love and sex, means that it figures largely in literature and art of the 18th and 19th centuries.

Keats' poem, "La Belle Dame Sans Merci (The Beautiful Lady Without Pity)" is often interpreted to represent the disease as a beautiful lover, who coldly strikes down kings, princes, and knights with no regard for their suffering:

I met a lady in the meads,
  Full beautiful—a faery’s child,
Her hair was long, her foot was light,
  And her eyes were wild.

...

I made a garland for her head,
  And bracelets too, and fragrant zone;
She look’d at me as she did love,
  And made sweet moan.

...

She found me roots of relish sweet,
  And honey wild, and manna dew,
And sure in language strange she said—
  “I love thee true.”

She took me to her elfin grot,
  And there she wept, and sigh’d fill sore,
And there I shut her wild wild eyes
  With kisses four.

...

I saw pale kings and princes too,
  Pale warriors, death-pale were they all;
They cried—“La Belle Dame sans Merci
  Hath thee in thrall!”

--John Keats, "La Belle Dame Sans Merci (The Beautiful Lady Without Pity)", 1884 accessed 21 August 2012


 

Twentieth-century medicine--specifically, the discovery of the antibiotic penicillin--made enormous inroads into the suffering caused by syphilis, and in the developed world, the disease is much more under control than it used to be. (It's a different story in the developing world, and that's a big enough topic to deserve its own post later on.)

But cases still occur, and although it's unlikely that you'll ever have a client suffering from untreated syphilis, it's not totally impossible, either.

Here's a case report of an MT who observed something suspicious, acted upon that suspicion, and probably saved the client's life, sparing him a great deal of suffering from the later stages of the disease, as well.

 

 


Case report:

Davies S, O'Farrell N. Syphilis referred from complementary medicine therapy. Int J STD AIDS. 2003 Sep;14(9):640-1. PMID: 14511505

 

 

Introduction

Syphilis is a disease with protean manifestations that often goes undetected in its early stages. Recently an upsurge in syphilis has been reported amongst gay men in various parts of the UK despite changes in sexual behaviour towards safer sex as a consequence of the HIV epidemic. We report a case of syphilis in which transmission occurred despite safer sex in which the diagnosis was flagged up by the observations of a complementary therapist.

 

Important take-home points:

  • Syphilis is "protean"--changeable, variable, flexible. It can take many forms.
  • Because it can be so changeable, its early stages--where it's most treatable--can go undetected. If the disease is missed in the early stages, that lays the groundwork for the devastating later stages that can include neurosyphilis and cardiac involvement.
  • The HIV epidemic has led to safer sex practices, which is turn had led to a decrease in syphilis rates, BUT recently (2003, as of this article) syphilis rates have surged higher--why this is the case, they do not say.
  • The MT was the one who observed the symptoms of syphilis in this client and referred him for diagnosis and treatment of what turned out to be a very serious disease.

 

Case report

A 50-year-old HIV-positive gay man attended a complementary therapist on the infectious diseases ward for a massage in July 2001.

 

Here's an example of where massage is incorporated into a hospital ward in a National Health Service (NHS) hospital in England.

We know the client is HIV-positive, so opportunistic infections--ones that take the opportunity of establishing themselves, with the immune system weakened by HIV--are always something to keep in mind as a risk for this client.

 

The masseuse noticed a rash on the patient’s feet that was not present on previous visits and referred him directly to the HIV clinic the same day.

 

Important take-home points:

  • Although the rash on the feet is part of the classic symptomatic presentation in Stage II syphilis, there are many other things it could be as well, and we never diagnose.
  • The MT referred the client directly to the HIV clinic (where there are primary healthcare providers to diagnose and treat), where he was seen the same day.

 

Without diagnosing, and without panicking the client, what might you say to get the client to follow up with their primary healthcare provider in a case like this?

If you think about what you might say, and rehearse it, then--if you ever need it--you won't be struggling to come up with words on the spot.

 

Six weeks previously he had noticed an infection around the nail on his left middle finger which had responded only partially to antibiotics from his general practitioner. He was otherwise well with an undetectable viral load, CD4 count of 640 cells/mL and was taking trizivir and efavirenz as antiretroviral therapy.

 

Again, we don't diagnose, and would never say so to the client--but it's pretty clear that that was the classic Stage I chancre (painless sore) presentation of syphilis.

It is interesting that it responded only partially to antibiotics from the GP. Did the GP miss anything? Would we comment on that to the client?

 

Figure 1. "Paronychia of middle finger—site of primary chancre" accessed 20 August 2012

 

He had a long-term male partner with whom he practised oral sex only. Six weeks previously he had contact with a casual male partner in a sauna in London where he had practised active digital rectal penetration but did not have penile penetrative anal sex.

 

Would we ever ask for this information in an intake or history?

Might this information ever come to us in a different way? If so, in what ways?

What would we do with this information?

If we have a problem with this behavior, would we tell the client?

What is the ethical way for a healthcare provider to deal with aspects of a client's sexual history that might make us uncomfortable?

 

On examination, he had a maculopapular rash over his trunk and the soles of his feet. A soft tissue swelling was apparent around the nail of his left middle finger, which was not ulcerated and resembled a paronychia (Figure 1). General examination was otherwise unremarkable.

 

Although the article did not include a picture of the client's rash, this is an example from Wikipedia of what a secondary syphilitic rash can look like:

Source: http://upload.wikimedia.org/wikipedia/commons/e/eb/2ndsyphil2.jpg accessed 21 August 2012

 

 

He underwent a sexual health screen, including urethral, pharyngeal and rectal swabs and syphilis serology. All results were negative except syphilis serology which showed: rapid plasma reagin test: positive 1:64, Treponema pallidum particle agglutination assay: positive, > 1280, syphilis IgM enzyme-linked immunosorbent assay (ELISA) positive, Syphilis IgG ELISA Positive.

 

Important take-home points:

  • His bloodwork tested negative for everything else, and positive for syphilis.

 

He was reviewed five days later with the results of these tests. The rash over his trunk had increased and he had developed painful papules over the palms of his hands. The apparent paronychia on his left middle finger remained. A diagnosis of secondary syphilis was made and he received an uneventful 14-day course of procaine penicillin 600,000 U by intramuscular injection. His regular partner received a full sexual health screen that was negative. The casual sexual contact was untraceable.

Discussion

The case is of interest for a number of aspects. It is probable that this patient’s primary chancre was the lesion noted on his left middle finger. Syphilitic chancres involving the hand with a paronychia have been reported but are uncommon[1,2]. Since the decline of syphilis in the 1980s there are no reports of syphilitic paronychias. This man developed syphilis despite practising 'safer sex'. Recently there has been an increase in syphilis in gay men in the UK. Most cases appear to be acquired from casual sexual contacts in meeting places where anonymity is a feature.

 

This is the sentence that stands out the most for me in this article, as it shows what real and important value our observations can provide to the client:

The abnormal rash was identified initially by a complementary practitioner who advised that a medical opinion be sought without delay.

 

The rest of the article is a summation of the situation at the time the article was written:

The Public Health Laboratory Service reports that the number of cases of syphilis in the UK has increased over the last 2 years[3]. In 2000 there were 321 cases of syphilis in England and Wales, and between 1998-2000 an increase of 191% was observed in males. A greater proportion of syphilis infections are transmitted amongst men who have sex with men than any other sexually transmitted infection. The risk of HIV transmission in gay men is also increased when a syphilis infection is present. Since 1997, there have been a number of outbreaks of syphilis in major cities, including Manchester and Brighton. In Manchester nearly half the cases diagnosed were in HIV-positive gay men[4].

Oral sex is quoted as an important factor in the transmission of syphilis in these outbreaks, although our case report highlights another potentially high-risk sexual practice. Whilst the risk of transmission of syphilis can be minimized by using a condom for oral and anal sex, other sexual practices perceived as low risk may still carry a risk of infection.

 

And, once again, the MT's role in observing something unusual and referring the client to a primary healthcare provider is re-emphasized:

The case also reinforces the need for all staff working within the field of HIV/genitourinary medicine and indeed, other health care professionals, to be vigilant for clinical signs in patients who otherwise appear asymptomatic. In this case it was the masseuse not the clinicians who identified the abnormal rash of secondary syphilis.

 

The importance of the MT's action should not be underestimated. We've seen what effects undetected and untreated syphilis can have over the course of decades.

By getting the client diagnosed and treated, the MT took action that probably saved the client years of suffering, followed by a dismal death.

Experiential hands-on learning: Ocean in a Jar (h/t Gwyn Jones) (#17/31)

Field trip! We're going to Padilla Bay tomorrow for a shore walk. /happydance!

One of the things that's so interesting about Padilla Bay is that it is an estuarine environment--it's where fresh river water joins the salt water of Puget Sound, so it's a transition zone between freshwater and saltwater.

Life at that intersection reflects aspects of both the sources that make up that environment.

I'll post pictures of any interesting littoral plants and animals that we come across on our shore walk.

Gwyneth Jones, an oceanography instructor at Bellevue College, has lots of fun and educational links and resources on her science division webpage.

"Ocean in a Jar (for fun): creating scented bath salts that resemble the sea" is printed on the bottom half of that PDF page.

It's a fun opportunity to create gifts for your friends, family, and clients, as well as products you can use in a spa-oriented practice--and learn a little ocean science at the same time!

And it's especially topical ( ☺! ) since we MTs are so closely involved with the skin and effects of topical products such as oils and lotions. Last year in Journal Club, we looked at the life-and-death importance of oil massage for infants in the developing world to help their skin protect them against infections and body heat loss.

Earth sciences, biology, and social science, among others, meet in this exploration of making topical products for the skin.

 

UPDATE, 19 August 5:33 PM PDT: I've gotten feedback that the link to her page does not work for everyone. I tested it, and because it works from my machine, I am not sure what I can do to fix it. I wonder if the fact that it's a PDF document is breaking it somehow?

I've reproduced the relevant section from her page here, as well, so that if the document doesn't work for you, you don't miss out on her recipe.

Ocean in a Jar (for fun)

I enjoy making bath salts, scented oils, lotions, etc for my friends, family, and self. I realized recently that the base recipe I use for bath salts creates "seawater"! (Lower salinity, unless you use a vat of the stuff, but most of the key elements/ions are in there.) Martha Stewart showed viewers a very similar recipe when she was on Oprah recently (though let's not get into how I know that, ahem, and she didn't draw parallels with oceanography for some reason...). My concoction, below, is a combination of recipes from "Natural Beauty at Home", by Janice Cox, plus some trial and error. You can play around with the proportions to suit your preferences.

Epsom salts, 1 cup - magnesium sulfate (MgSO4 ·7H2O) - available (cheap) in drugstore aches-and-pains aisle

Kosher salt or coarse sea salt*, 1/4 cup - sodium chloride (NaCl)

* You can substitute baking soda (sodium bicarbonate, NaHCO3) and/or cornstarch (organic stuff), for some or all of the kosher/sea salt.

Optional:

Vegetable oil, about 1/8 cup - almond, coconut, avocado, walnut, olive... - If only oil spills were vege oils!

Food coloring, a few drops - the kind you can get in the grocery store baking aisle in little bottles

Essential oil, a few drops (I use the pure, natural ones) - lemon, rosemary, lavender, rose, mint, pine...

Mix the ingredients together well, by shaking in a jar with lid or in a Ziploc-type bag. It will take a couple minutes of shaking to distribute the oils and color well. I like using a bag so I can work out some of the colored lumps with my fingers.

To use, add about 1/4 cup to running bathwater. It will keep a month or so in a closed container. Not edible, so keep away from youngsters, pets, etc. With vegetable oil added, you can also use it as an exfoliating, moisturizing salt rub (my sister-in-law the kickboxer loves it this way): Add a little water to a handful of the salts and then rub on damp body skin in the shower; rinse with warm water. Don't use it as a rub if your skin is broken out or sensitive, and don't use it on your face (too irritating).

Enjoy! ☺ Gwyn

 

 


VERY IMPORTANT:

Remember, Epsom salts and essential oils are not edible, so keep this mixture stored in a safe place where children and animals can't accidentally poison themselves by eating it.

 

 


Reading the recipe is pretty straightforward. There are a couple of technical terms I'll note, but we don't need to wait until we get around to discussing the chemistry in order to use the recipe.

Salinity is the measurement of how salty a liquid is. The Earth's oceans are not equally salty everywhere; here's a map of how much they can vary from one region to another.

Source: http://upload.wikimedia.org/wikipedia/commons/f/f7/WOA05_sea-surf_SAL_AYool.png accessed 17 August 2012

 

By "elements/ions" she means the chemicals in different kinds of salt--there's the table salt (sodium chloride) that we're all familiar with, but there are many other kinds of salts as well.

Not all salts are edible, which is why there's a warning on the Epsom salts (magnesium sulfate).

We'll discuss the chemistry more later, but here at least, it looks like tomorrow will be a perfect day for going ahead with this activity in the meantime.

So I'm inviting you to take a little time to make some bath salts, following Jones' "Ocean in a Jar" recipe, and improvising with different oils that you like.

Have fun! If you hit on any combination you especially like, you're invited to share it with us in the comments.

Creating new massage knowledge: A hypothesis about reducing surgical infection risk by promoting skin integrity with massage oil

Can we take the knowledge from last month's Journal Club and put it together with different research in a different specialty with a different population of clients/patients to produce a new and testable hypothesis about how massage oil (with or without massage, as appropriate) can provide benefit to those clients/patients?

Information that will be relevant to us is summed up in these comments from Journal Club:

 

Let's combine what we know from Journal Club with the following information:

Heal and her team tested a single application of a strong antibiotic, chloramphenicol, in the prevention of infection in minor dermatological surgery.

Heal CF, Buettner PG, Cruickshank R, Graham D, Browning S, Pendergast J, Drobetz H, Gluer R, Lisec C. Does single application of topical chloramphenicol to high risk sutured wounds reduce incidence of wound infection after minor surgery? Prospective randomised placebo controlled double blind trial. BMJ. 2009 Jan 15;338:a2812. doi: 10.1136/bmj.a2812.
 
Abstract: OBJECTIVE: To determine the effectiveness of a single application of topical chloramphenicol ointment in preventing wound infection after minor dermatological surgery. DESIGN: Prospective randomised placebo controlled double blind multicentre trial. SETTING: Primary care in a regional centre in Queensland, Australia. PARTICIPANTS: 972 minor surgery patients. INTERVENTIONS: A single topical dose of chloramphenicol (n=488) or paraffin ointment (n=484; placebo). MAIN OUTCOME MEASURE: Incidence of infection. RESULTS: The incidence of infection in the chloramphenicol group (6.6%; 95% confidence interval 4.9 to 8.8) was significantly lower than that in the control group (11.0%; 7.9 to 15.1) (P=0.010). The absolute reduction in infection rate was 4.4%, the relative reduction was 40%, and the relative risk of wound infection in the control group was 1.7 (95% confidence interval 1.1 to 2.5) times higher than in the intervention group. The number needed to treat was 22.8. CONCLUSION: Application of a single dose of topical chloramphenicol to high risk sutured wounds after minor surgery produces a moderate absolute reduction in infection rate that is statistically but not clinically significant. Trial registration Current Controlled Trials ISRCTN73223053. [1]
 
So the chloramphenicol worked, but the improvement was not clinically significant (meaning, it was not relevant on a practical basis for a clinician trying to decide whether it makes sense to use it).
 
In a response to the article, Grey, Healy, and Harding argue that:
In clean minor surgery meticulous preoperative preparation and aseptic technique by appropriately trained practitioners with access to appropriate facilities will prevent most surgical site infections without antibiotic prophylaxis [preventive treatment]. [2]
 
Weatherhead and Lawrence point out that:
Heal and collegaues report a reduced risk of wound infection with topical antibiotics after minor skin surgery. However, the control group had a high risk of infection and the influence of pre-existing carriage of skin pathogens, as shown by the appearance of the lesion's surface, was not considered.
 
Our prospective study shows that patients whose lesion preoperatively had a crusted or ulcerated skin surface were significantly more likely to develop clinical wound infections than patients whose lesion had a normal or scaly surface.
 
...
 
The risk of infection was significantly increased (P<0.05) for crusted and ulcerated skin surfaces compared with intact skin surfaces, and for ulcerated surfaces compared with scaly surfaces. It was not affected by perioperative topical antibiotics, site of the lesion, closure technique, or surgeon experience. Staphylococcus aureus was the causative organism in 18 out of 20 infections. Patient age was a significant risk factor, and older patients were more likely to have lesions with a broken surface. [3]
 
 
Taking all of this information together, can we come up with a testable hypothesis that might--if validated by research--help this group of clients/patients avoid infection after minor surgery in a safe, effective, and cost-effective way?
 
What is the first question that you would ask--what do you want to know in order to start thinking about whether massage or massage oil would be appropriate for these clients/patients?
 

Experiential hands-on learning: Ocean in a Jar (h/t Gwyn Jones)

Now that the weather's turning cooler here in the Seattle area, I'm looking forward to autumn walks on the beach. Under a gray sky, it's a very different experience from summer outings to Puget Sound, but I think I might just enjoy autumn on the beach even better.

Foundational concepts: Testing for allergic or irritant contact dermatitis with a patch test

This is good advice all year around, but with Halloween approaching, and people wearing costumes and makeup that they don't normally use, it's especially timely right about now.

(UPDATE, 8:34 PM PT--I wanted to pass on this memorable Halloween story from Laura Allen, but wanted to make sure I had her permission to quote her, since where she wrote it was not in a public forum:

A word to the wise: a couple of years ago I got my costume and it included a pair of those crazy big false eyelashes. I put them on just before we left the house. We didn't get two miles down the road before my head started swelling, my eyes closed, and I thought I'd croak. I've never been allergic to anything but I had a reaction to the eyelash glue. Beware of that stuff! I missed the party altogether!

 

Reading that story this morning reminded me that I wanted to write about carrying out a patch test to look for allergy or irritation from using oils or other substances.

Contact dermatitis (Greek "δέρμα" ["derma"], skin + Latin "-itis", inflammation) is a rash, irritation, or other skin reaction that occurs when the skin comes into contact with an allergen (allergy-creating substance) or an irritant substance.

 

Source: http://upload.wikimedia.org/wikipedia/commons/a/a8/Contact_dermatitis_around_wound.jpg accessed 5 October 2011

 

The Wikipedia entry on contact dermatitis contains a good introductory explanation, as well as an explanation of what to do in the way of self-care if you experience contact with an irritant or allergen.

As massage therapists, we use a number of topical products (products applied to the skin), such as massage oils, as well as aromatherapy and other inhalants.

In the References section that follows, I've put some references from PubMed about allergic/irritant contact dermatitis with products that an MT might come into contact with [1-11]. This was by no means a systematic evaluation of what's out there; I just took 11 examples from the first page of 572 results returned by PubMed; there's much more out there if I had taken the time to go through them systematically.

If you have any reason at all to suspect that you or a client may be allergic to a product, it is wise to conduct a limited patch test before you use it.

Remember that allergies can develop after repeated exposure to a substance, even if you have not been allergic to that substance in the past.

The wikiHow article on How to Patch Test Skin is a good overview; however, I recommend an extra couple of steps for safety.

For yourself:

If you are patch-testing on your own elbow or wrist to see whether you yourself are allergic to a product, make sure that you don't do it when you are totally alone.

Patch testing typically causes either nothing to happen (if you're not allergic to or irritated by the substance), or else, a skin rash or some other form of lesion (blisters, itching) (if you are allergic to the substance).

Very, very rarely does it ever lead to potentially fatal respiratory distress, because it doesn't involve injecting the substance into the skin or bloodstream with needles. But the possibility of respiratory distress happening due to anaphylactic shock is not exactly zero, either. It is extremely rare, but it does happen--cases of anaphylactic shock from latex gloves, for example, in medical personnel who developed an allergy have been reported just from topical exposure.

Because of that extremely tiny yet non-zero possibility, I recommend that you never conduct a patch test when you are going to be entirely alone for an extended period of time. You should have someone available nearby whom you could alert if you are having breathing problems, so you can get prompt lifesaving medical care if necessary.

 

For your client:

If you are patch-testing on a client's elbow or wrist to see whether they are allergic to a product, make sure to recommend to them that they not do the test if they are going to be totally alone for the next few hours (for the same reasons just described).

Also, if possible, have them wait in your waiting area for about 15 minutes after the test before you send them on their way, just to make sure that no severe symptoms come up immediately--or, if they do, that you can take appropriate first aid responder action.

 

And speaking of safety:

Also, never use peanut oil on children, and never recommend to parents that they massage their child with peanut oil.

Don't do it!

Life-threatening peanut allergies are relatively rare, but--when they do happen--the consequences are so bad--up to and including death by anaphylactic shock--that it is not worth taking the chance. There are plenty of other oils that do not carry the same risks for children with allergies.

Ok, with those safety notes laid out, here's the procedure for conducting a patch test on the elbow or wrist to test to see whether a substance provokes a skin reaction:

  1. Apply the substance to a 1-inch-long by 1-inch-wide area of skin that you can easily observe--most of the time, the wrist or the inside of the elbow is used.

  2. Leave the area undisturbed and unwashed for 24-48 hours, to give the skin the time to show any reaction which may develop.
     
  3. Watch for signs of a reaction: redness, itchiness, blistering, rash, or other symptoms.

  4. VERY IMPORTANT: If you experience nausea or difficulty breathing, seek medical help right away.
     
  5. If there is no reaction, then the product is probably safe for you to use. Remember, though, that if a product is safe at one time, you can still develop an allergy to it at some future point.
