Athlete's foot in the context of "Trichophyton"

Sandals are an open type of footwear consisting of a sole held to the wearer's foot by straps that go over the instep and around the ankle. Sandals may also feature a heel of varying heights. While the distinction between sandals and other types of footwear can sometimes be unclear (as with huaraches—the woven leather footwear from Mexico—and peep-toe pumps), sandals are generally understood to leave most of the foot exposed.

People choose to wear sandals for several reasons, including comfort in warm weather, economic benefits (sandals typically require less material than closed shoes and are easier to manufacture), and as a fashion statement. Sandals are commonly worn in warmer climates or during warmer seasons to keep feet cool and dry. The open design reduces the risk of developing athlete's foot compared to enclosed shoes, and wearing sandals may be part of the treatment regimen for such infections.

An antifungal medication, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others. Such drugs are usually obtained by a doctor's prescription, but a few are available over the counter (OTC). The evolution of antifungal resistance is a growing threat to health globally.

A medical classification is used to transform descriptions of medical diagnoses or procedures into standardized statistical code in a process known as clinical coding. Diagnosis classifications list diagnosis codes, which are used to track diseases and other health conditions, inclusive of chronic diseases such as diabetes mellitus and heart disease, and infectious diseases such as norovirus, the flu, and athlete's foot. Procedure classifications list procedure codes, which are used to capture interventional data. These diagnosis and procedure codes are used by health care providers, government health programs, private health insurance companies, workers' compensation carriers, software developers, and others for a variety of applications in medicine, public health and medical informatics, including:

• statistical analysis of diseases and therapeutic actions
• reimbursement (e.g., to process claims in medical billing based on diagnosis-related groups)
• knowledge-based and decision support systems
• direct surveillance of epidemic or pandemic outbreaks
• In forensic science and judiciary settings

There are country specific standards and international classification systems.

Onychomycosis, also known as tinea unguium, is a fungal infection of the nail. Symptoms may include white or yellow nail discoloration, thickening of the nail, and separation of the nail from the nail bed. Fingernails may be affected, but it is more common for toenails. Complications may include cellulitis of the lower leg.A number of different types of fungus can cause onychomycosis, including dermatophytes and Fusarium. Risk factors include athlete's foot, other nail diseases, exposure to someone with the condition, peripheral vascular disease, and poor immune function. The diagnosis is generally suspected based on the appearance and confirmed by laboratory testing.

Onychomycosis does not necessarily require treatment. The antifungal medication terbinafine taken by mouth appears to be the most effective but is associated with liver problems. Trimming the affected nails when on treatment also appears useful.

Tinea manuum is a fungal infection of the hand, mostly a type of dermatophytosis, often part of two feet-one hand syndrome. There is diffuse scaling on the palms or back of usually one hand and the palmar creases appear more prominent. When both hands are affected, the rash looks different on each hand, with palmar creases appearing whitish if the infection has been present for a long time. It can be itchy and look slightly raised. Nails may also be affected.

The most common cause is Trichophyton rubrum. The infection can result from touching another area of the body with a fungal infection such as athlete's foot or fungal infection of the groin, contact with an infected person or animal, or contact with soil or contaminated towels. Risk factors include diabetes, high blood pressure, weak immune system, humid surroundings, excessive sweating, recurrent hand trauma and cracks in the feet. Pet owners and farmworkers are also at higher risk. Machine operators, mechanics, gas and electricity workers, and people who work with chemicals have also been reported to be at greater risk.
