Skin Conditions and Infections

Jogger's or Runner's Nipples

Jogger's nipples or runner's nipples is a condition caused by the constant friction between a runner's nipples and shirt, which causes chafing of the nipples and areola. Jogger's nipples is probably the term most often used, since the condition is more prevalent in long distance runners. It is also called fissure of the nipple. It is similar to the nipple irritation sometimes experienced by breastfeeding mothers. Surfers who do not wear rash guards may also have this problem. It is more of a problem during hot, humid days and can also happen to bike riders.

Jock Itch (Tinea Cruris): Symptoms, Causes, and Treatment

Jock itch is a tinea infection of the groin area including the upper medial thighs, perineum, perianal region, and the buttocks. It usually does not affect the scrotum or penis, nor does it often spread beyond the groin area. It is also called tinea cruris, the word cruris coming from the Latin word for leg.

The name jock itch comes from its association with the male athletic supporter (jock strap), which not only can produce friction and moisture, two predisposing factors for a fungal infection, but which often go unwashed for long periods and therefore can harbor fungal organisms. However, wearing a supporter is not necessary in order to be affected by jock itch, a predominantly male condition.

Impetigo in Athletes: Symptoms, Causes, and Treatment

Impetigo is a contagious bacterial skin infection that is prevalent in children. Characterized by the eruption of yellowish-red (honey colored) pustules, it also affects athletes who are in frequent close contact with each other. It is common in wrestlers, boxers, swimmers, and gymnasts. Rugby players and football players may also be at high risk. The infection is commonly caused by Staphylococcus aureus bacteria, but also sometimes Staphylococcus pyogenes. The pustules may itch and burn and when they erupt, more pustules will be created. The areas most affected are the ones subject to high friction.

Pitted and Smelly Feet: Pitted Keratolysis

What Causes Little Holes in Feet?

Pitted Keratolysis is an infection of the skin of the feet caused by a bacterial infection. Excessive sweating and tight, unventilated shoes can predispose you to this condition. The primary symptoms of this foot infection are bad foot odor and shallow pits on the bottom weight-bearing (plantar) surface of the feet. Most people describe this as "little holes on the bottom of my feet." However, it is their smelly feet that leads most people to seek treatment since there are rarely any other symptoms. Redness, soreness, and itching of the feet are also possible. This infection rarely occurs on the palms of the hands.

Sports Induced Acne From Helmets, Pads, and Other Gear

Acne caused by sports activities is often a type of acne called acne mechanica. This acne is caused by the combination of pressure, friction, heat, humidity, and occlusion. Any repeated and prolonged mechanical irritation to the skin, such as rubbing, pressure, friction, pinching or pulling can produce these inflammatory papules and pustules.1 Severe cases may progress to nodules and cysts. Rather than being a primary acne, it is an exacerbation of an underlying acne, where the inflammatory lesions become much worse.

Athlete's Foot

Athlete's Foot is a fungal infection of the foot also known medically as tinea pedis. These infections are caused by various dermatophytes, the most common of which are Trichophyton rubrum, T. metagrophytes, and Epidermophyton floccosum. These fungal organisms invade the outer layers of the skin, causing itching, burning, scaling, cracking and redness. Sometimes, oozing, crusty blisters can form. There can also be infection with no symptoms. The infection thrives in warm moist areas, hence the association with athlete's, whose feet are kept moist and warm for long periods of time from sweat and exertion in shoes. This infection is certainly not limited to athletes. Anyone can get it.

Can Shingles Cause Pain in the Shoulder Blades?

The term "shingles" refers to a condition caused by the varicella zoster virus, the same virus that causes chicken pox disease. After a person has had the chicken pox, the virus remains dormant, residing in nerve cells. Later on, as a result of many different factors, the virus may reactivate and leave the nerve cell and this is what causes herpes zoster, or shingles.

Diet and Acne: What is the Evidence?

Acne sufferers have been reporting an association between specific food intake and acne outbreaks for many years. For instance, many many people have claimed that chocolate consumption either exacerbated or caused acne outbreaks. In fact, that chocolate causes acne was once accepted as fact by the lay public. Fatty foods are also frequently implicated. Milk and dairy products have been long associated with acne as well. However most studies have failed to find a correlation between diet and acne and it was long concluded that genetic predisposition and hormonal factors played the largest role.
