At the San Roman Clinic we carefully assess any alteration at the level of the nails, as well as the foot as a whole. The skin infections that mainly affect the feet are:
1.Paronychia (also known as nail tag): an infection that surrounds the nails and causes inflammation (pain, swelling and redness of the skin and even pus) and destruction of the cuticle. It can be of acute origin, generally bacterial (S. Aureus and Streptococcus), or chronic, caused by fungi (mainly Candida) and sometimes by mixed infections. It is often the result of an ingrown toenail. Treatment is broad and, depending on the origin, may consist of drainage of the pus, antibiotic or antifungal treatment, as well as other conservative measures. Sometimes surgical exesis (removal) of the nail may be necessary.
Onychomycosis: the most frequent infection of all. It consists of an infection of the nail by fungi (molds, dermatophytes or Candida). The appearance of the nail in this case is different, with changes in color, thickening and flaking, as well as brittleness.
Dermatophyte infection: cutaneous fungi can affect any part of the body, and the most frequent sites are the feet (ringworm of the foot known as “athlete’s foot”) and the nails (nail ringworm). Athlete’s foot presents with maceration, fissures and interdigital (i.e. between the toes) desquamation.
Who suffers from them and how do they contract?
Fungal infections are very common and their incidence is on the rise due to factors such as advanced age, diabetes, peripheral vascular disease (poor circulation in the legs) and other diseases that condition a state of immunosuppression, but especially is due to everyday factors such as exposure to humid and warm environments such as swimming pools, showers and changing rooms in sports and leisure facilities, where these infectious agents tend to grow.. The route of infection can come from humans, animals and soil. Onychomycosis is more frequent in men and is also related to the use of non-breathable footwear due to the humidity that can be generated.
