Re: Nail and foot fungus
The definitive answer is; Fungicide.
Then again, it depends. As with all things pathological, each case has to evaluated and treatment plans formulated according to the patients individual needs and medical history. Expected recurrance of infection has to be addressed. Personally, I encourage pts to maintain control of chronic tinea, you`ll never completely eradicate it. -
Re: Nail and foot fungus
clients have become a bit warey re the oral anti fungal agents, just wondering what the milage is in Tea Tree oil and laser therapy??

Hello Rachel
Why have patients become a bit wary re: oral anti-fungal agents? I have not experienced this.
All the best

Because GP's seem to be very keen in explaining that they will cause liver failure.
It may be quicker to do that than arrange microscopy, follow up and prescription.
For reference, pathways (that I know of) for oral terbinafine require positive microscopy before prescription. I've seen quite a few blatantly obvious OM nails that have come back negative (nail samples not taken by us though??) and nothing prescribed.
To be fair though, it's not a life threatening condition is it. Should the NHS be funding what could be described as, in most cases, a cosmetic problem. -

Hi Steve
I do know of several GP's in my area that refuse to send patients clippings for analysis . They usually send them for otc preperations or Rx Loceryl.
Oral terbinafine has been identified to cause liver damage in some cases so I try and strike a balance between the risks and the severity of the condition in deciding a course of action.
Cheers Fella

I`d like to see the `evidence` that oral terbinafine causes liver damage. This is postulated by some, not all, GP`s. I contest that any medicament, particulary when administered orally or IV, has `an effect` on the liver as all medication has to be metabolised by the liver!
The RCT which GP`s like to refer to is the one where a 48 year old woman developed hepatoxicity (and subsequently required a liver transplantation as she already had severe cirrhosis) after taking terbinafine. However, they often fail to mention that she was also taking dosulepin and propranolol, anti-depressants which oddly enough have `an effect` on the liver:rolleyes:
See here;http://bestpractice.bmj.com/best-practice/evidence/intervention/1715/0/sr-1715-i3.html
A quote from the above;
RCTs involving terbinafine frequently measured levels of liver enzymes and found that increases were asymptomatic, and reversed once the drug was stopped. Adverse events unique to terbinafine include sensory loss such as taste, smell, or hearing disturbance ( see option on oral griseofulvin and option on oral itraconazole).
Oral terbinafine has been declared safe after many trials, such as these;

http://www.ncbi.nlm.nih.gov/pubmed/16730616
I agree with Wellsieboy, it is not merely a cosmetic problem, it is an infection which poses a substantial risk to undermine the integrity of the epidermis and subsequent bacterial infection. There have been a number of studies which identify a correlation between cellulitis and tinea infection.

Taken from the official FDA information site
That was my understanding of the side effects , hence my comment to make a balance made on hard medical evidence before suggesting systemic Tx.
Are we as podiatrists qualified or have the knowledge to assess which of our patients have / have not got liver disease at whatever stage ???

Exactly. I`m not disagreeing with you, Del. Of course balance, or evaluation, should always be taken before recommending any treatment.
Hence, if the pt has any chance of liver dysfunction/impairment the same site (which contains information approved by the FDA ;)) which you quoted from advises;
Your doctor should do a blood test to check you for liver problems before you take Terbinafine HCl.
Maybe tinea in itself is not `life-threatening`, but it does increase risk of further complications with co-morbidities. I can also understand the reluctance of GPs to spend NHS money on obtaining and culturing nail and skin samples. That is why I offer to take the samples myself and send them directly to the path lab for a microbiology and culture report. It does cost the pt £35, but many are willing to pay this if it provides a definitive diagnosis, which a GP requires, to be prescribed the appropriate medication.
Remember, terbinafine is not the only anti-fungal, griseofulvin (the only oral anti-fungal approved for children) and any of `azole` family are also effective.
Cheers,

Whatever

For interest purposes: When in the UK I was told that Wicks Vapour Rub works very well on fungal nails - tried and proved to be successful although fairly slow. Now in Oz have suggested this to several patients and proving to be very successful, especially if the toenail is chauxic and painful. - also something cheap and which most households readily have available. Having checked with a specialist first he was happy that I give this advice, although some GPs suggest that it should not be used if client is on Warfarin (so I advise those clients on the standard topical treatments) - specialist unaware of any reason why the GPs believe this. I have suggested this over the two years here and have some very happy customers. :D

Thanks for that.

I am VERY grateful to Bel for her post of 11th October and in particular a paper she highlighted:
Dermatology for the practicing allergist: Tinea pedis and its complications (Hasan, Fitzgerald, Saoudian and Krishnaswamy)
Also her comment:
QUOTE: I agree with Wellsieboy, it is not merely a cosmetic problem, it is an infection which poses a substantial risk to undermine the integrity of the epidermis and subsequent bacterial infection. There have been a number of studies which identify a correlation between cellulitis and tinea infection.
As this paper cleared up a conundrum I was struggling with.... that of GPs (repeated) non-detection of fungal infiltration (of typical presentation of interdigital 4th/5th Tinea Pedis) in a patient who (because of a missed diagnosis) went on to have protracted ill-health rising from cellulitis then osteomyelitis and eventually, Atrial Fib (in a clinically ‘well’ pt.!) (Interestingly this was my 1st patient in PP after graduating, and its resolution, gave a real boost to my confidence!)
Basically: Pt. presented with 12 mths ‘rash’ treated with topical antibiotics, steroid cream (pt. self-prescribing!) oral antiBs x 4 and eventually a stay in hospital with intravenous antiBs!
To my (unpractised) eye it was Tinea Pedis... no mistake! (although it had progressed to dorsum/plantar) I asked whether she had had a test for fungal infection to which she replied .... 3 times ALL NEGATIVE!!
I said despite negative results I felt it always prudent to treat the simplest cause first.... so she was started on Lamisil x 2 daily and I saw her again in 2 weeks. (I told her to avoid using the steroid and other creams)
[What MUST be mentioned here was her shoes..... plastic court shoes with such a growth of fungus in it was impossible to miss!!!! I urged her to throw them away!!! ... and use Daktarin in any future shoes BEFORE wear.
Next visit. All itching had stopped ‘rash’ was drying out – practically gone. Patient was angry!!! Actually not at me! She could NOT believe GP hadn’t spotted this and treated her!!!! She was STILL wearing fungus-shoes!!!
Next visit: 2 weeks. ALL GONE! (including shoes!!!) Told pt. to use Lamisil as and when any signs of itching as TP very likely to recur, also continue spraying shoes... (she HAD been tested for DM incidentally)
The vital message here is in the paper above that Bel highlighted (above)....and I quote below its take-home message:-
“In some patients gram-negative infection may complicate tinea pedis. Gram-positive bacteria usually dominate the interdigital spaces of the feet and upon infection with dermatophytes, bacterial products similar to penicillin may inhibit their growth. This may result in a predominant growth of gram-negative bacteria like pseudomonas, proteus and klebsiella, leading to gram-negative cellulitis. In such situations, demonstration of fungal elements may become difficult as excessive gram-negative bacterial presence may inhibit fungal growth and make it harder to detect fungal hyphae on KOH preparations. Antifungal agents released from the gram-negative bacteria may also contribute to decreased presence of fungus. Hence, cultures of skin scraping may demonstrate gram-negative bacteria but no fungal pathogens(!!!) Aggressive treatment of the underlying fungal as well as the gram-negative bacterial infection can, however, lead to amelioration of cellulitis in these patients.”
Brilliant learning example (for me) and one of the main reasons I frequent PA (rather TOO much LOL!) and the answer to WHY Tinea Pedis wasn’t treated at the start and the unfortunate sequelae (above) avoided!! Thanks Bel you ARE the Dermatology Queen!! -
Hi,
Here in Canada I am using Formula 3 for nail fungus - a topical with much better results and compliance than Penlac. Not sure if it is available elsewhere. -
http://www.everyclick.com/feet-first-worldwide/ct17193
......reveals the actve ingredient for F3 is Tolnaftate; a fungistatic (prevents spore reproduction). Penlac is also a fungistatic anti-fungal, with Ciclopirox being the active ingredient.
Not sure if Amorolfine 5% is licensed for podiatric use where you are, but it`s prescribed here as a`new chemical class`, reportedly fungicidal in action, albeit in vitro studies only;

Hope that helps!

Hi BLinda
Lots of interesting and informative reading there, thanks very much. Can you please tell me what lab you send your nail clippings to for analysis. -
I send tissue samples to the path lab of my local hospital;
http://www.hampshirehospitals.nhs.u...sts/royal-hampshire-county-hospital_rbe6ciui/
I have a good professional relationship with the path lab as I made contact with them and asked if I could spend an observational day with them (watching the microscopy and culture of samples) with a view to sending them samples, shortly after I graduated. I would thoroughly recommend it.
Chin, chin
Bel
BTW, I don`t EVER send `nail clippings`, you need to harvest subungual tissue (and plenty of it) from the active (most proximal) part of the infection for an accurate dx.
