Five minute fungus

Following on from our last blog on fungal infections, we are excited to introduce the first fungal nail testing available to Podiatrists, Five Minute Fungus. 

For many years Podiatrists have been able to identify and advise on treatment for fungal nail conditions. Unfortunately, we haven’t been able to confirm diagnosis through testing, until now. Previously we had to ask the patient to obtain a nail clipping kit from their GP, take a sample, ask the patient to return the sample to the GP, who would then send this to a lab to be tested and then wait around 3 weeks for the results! Now we are able to test a sample the nail in clinic and have the results within five minutes. Where do we sign up!

First time for a bit revision. Fungal infections are one of the most common complaints that Podiatrist’s see in clinics around the globe. They are the third most common skin disease in the World. Primarily fungal infections occur on the skin, this condition is known as Tinea Pedis or commonly known as Athletes foot. Once on the skin it can transfer to finger nails and toenails, by a process which is said to take around two years. The nail condition is then known as Onychomycosis. Three percent of the adult population of the UK are said to have a fungal nail infection.

What causes a fungal infection?

Fungi called Dermatophytes live harmlessly on the skin. In a fungal infection these dermatophytes multiply if the conditions for them to thrive are just right, causing a huge increase in the incidence of dermatophytes. In fungal infections of the nail and skin the main dermatophytes involved are Trichophyton Rubrum and Trichophyton Interdigitale. Dermatophytes thrive in warm, dark, moist areas, which is why feet, shoes and socks are the perfect climate for them.

There are many factors that can increase your chances of developing a fungal infection, these include;

·    Being male

·    Increasing age

·    Occlusive footwear

·    Poor personal hygiene

·    Repeated nail trauma

·    Genetic predisposition

·    Health conditions such as Diabetes, poor circulation, HIV infection and immunosuppression

What does a fungal infection look like?

In the nails;

·    Colour can change to brown, yellow, green and even black

·    Texture can change becoming thicker and more brittle

·    Often have a distinct musty smell

·    Stripes and lines can appear 

·    Podiatrists commonly diagnose fungal skin infections by your symptoms and looking at the skin on your feet. 

Nail fungal infections require testing to confirm a diagnosis. 

What is the process of Five Minute Fungus entail?

Five Minute Fungus uses a test with an accuracy of 97% for the most common nail dermatophytes. The Five Minute Fungus test gives us rapid results within 5 minutes. It does not require us to send samples away, we can test the nail in the clinic on the day.

Firstly,we trim the nail to obtain a sample of the affected nail. We then use a testing system similar to that of a pregnancy test, to test for the presence of onychomycosis in the nail. The test confirms if there is the presence of the dermatophytes or if the sample is clear. Once we have our results we tailor a treatment plan to you. Your plan will include treatment for the skin, nails and your socks and shoes. 

We will also send a letter to your GP with your results and an indication of your treatment plan.

Once treatment is complete we can retest the nail to confirm if the presence of the fungus is gone, following the same process.

From a young age I always knew I wanted to do a job that involved helping people. I remember as a child trying to convince family members to play games of Drs and nurses with me. Sticking plasters on imaginary wounds and listening to hearts with my plastic stethoscope. I had grown up in a family where both my parents and grandparents were Podiatrists, so I was used to hearing discussions about people's health and the family business at the dinner table. As a pre-school child I remember visiting a nursing home with my mum as I sat on a big chair being fed biscuits by a line of patients waiting to have their feet treated. My Mum's clinic was annex from our family home, as it still is to this day, so I was used to being in and around a clinical setting. 

As I grew up I was really interested in learning about the sciences, especially human biology. So when it came to make my subject choices in 2nd year of high school it was an easy decision to take three sciences. Unlike a lot of people my age I knew that my future lay in healthcare, but I wasn't sure in exactly what field. 

When I was 17 years old our school encouraged us to do work experience. I knew this was my opportunity to see a bit more about what other health professionals did. I managed to get a placement at The Western General hospital in Edinburgh based at the Neurosurgical department. I spent two incredible weeks shadowing lots of medical professionals from brain surgeons, to Drs, specialist nurses, physiotherapists and occupational therapists. I even managed to chat to patients and their families on the wards. I loved every minute of the experience. One of the most unforgettable experiences was being invited into the operating theatre to observe a brain surgery. The team were so welcoming and made me feel completely at ease in this dramatically different environment. From that minute on, I was hooked! I knew that this was something I needed to do.

I did as most students in Scotland do I filled in my UCAS forms and waited to see what would happen next. I applied to a variety of allied health professions including optometry, podiatry and even medical sciences. I was invited for an interview at the Podiatry department at Queen Margaret University in Edinburgh and was delighted. I remember walking into the department and it just feeling right. After that everything seemed to fall into place! I received an unconditional offer and the rest they say is history! 

I studied Podiatric medicine at QMU for four years, graduating with a 1st class honours degree. I really enjoyed my time at university and met some incredible lecturers and friends along the way. I felt that I had more to prove than others coming from a family of Podiatrists, people assumed I knew the syllabus already, possibly by osmosis. But I worked hard to prove that I was no different from any other student.
