Skin Issues
Dermatological issues are some of the most common medical conditions faced by a football team physician. Skin infections in particular can pose a significant challenge both diagnostically as well as from a clearance-to-play perspective, given the potential for infections to affect other participants, such as other members of the team. Skin infection rates vary by sport and age group, with one study reporting 28.56 infections per 100,000 athletic exposures in high school wrestlers, which was more than 10 times that of football.14 Still, football players are at a higher risk of skin infections given the contact nature of the sport and close person-to-person proximity. A precise diagnosis may be difficult early in the course of a skin eruption, and with differing guidelines from various professional societies, it may be best suited for medical personnel familiar with these conditions, such as a sports medicine physician or dermatologist, to manage these athletes. A thorough and systematic evaluation is recommended, as athletes are often treated with unnecessary antibiotics, which contributes to antibiotic resistance. Previous antibiotic use may also be a risk factor for developing community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA).15
Two terms sports medicine clinicians must be familiar with are “adequately protected” and “properly covered.” The National Collegiate Athletic Association (NCAA) defines a wound or skin condition as adequately protected when the condition is considered noninfectious, adequately treated by a healthcare provider, and is able to be properly covered. A skin infection is considered properly covered when the lesion is covered by a securely attached bandage or dressing that will contain all drainage and remain intact throughout the sport activity.16
Impetigo
Impetigo is often caused by Staphylococcus and Streptococcus subspecies. The classic presentation is a dry, honey-crusted lesion with an erythematous base. Culture or gram stain may be helpful, but treatment may be initiated on a clinical basis without these studies. Topical antibiotics may be used, but in the setting of multiple lesions or an outbreak, systemic (eg, oral) antibiotics are preferred. Oral antibiotics may also shorten the time to return to play. If not responsive to the initial treatment, MRSA should be considered. No new lesions for 48 hours and a minimum of 72 hours of therapy with no moist, exudative, or draining lesions are required prior to return to play. These lesions cannot be covered as the sole means of return to play.
Methicillin-Resistant Staphylococcus aureus
MRSA is one of the most challenging skin infections for the sports medicine clinician to manage. Several outbreaks have been reported in the high school, college, and professional settings.17-20 Standardized precautions and a proactive approach are key in preventing MRSA outbreaks. It appears that different activities within a given sport may contribute to MRSA risk. One study reported football linemen had the highest attack rate, while another study reported cornerbacks and wide receivers to have the highest rate of MRSA infections.17,20 The elbow area was the most common site infected in both studies.
Abscesses are best initially managed by incision and drainage as well as obtaining wound cultures (Figure 5).
In the absence of systemic symptoms or cellulitis, oral antibiotics may not be necessary. However, should antibiotics be considered, depending on local resistance patterns, antibiotic choices include sulfamethoxazole-trimethoprim, doxycycline, or clindamycin.Preventative measures are thought to be useful, especially in the management of teams. The Centers for Disease Control and Prevention has published guidelines for both clinicians and patients. Precautions including hand washing; encouraging good overall hygiene; avoiding whirlpools; discouraging the sharing of towels, razors, and athletic gear; maintaining clean equipment/facilities; and encouraging early reporting of skin lesions.14,17,21,22 Isolated cases of MRSA do not need to be reported, but if more than one athlete is infected, one should notify the athletic training and team coaching staff. In the setting of an outbreak, the physician may need to notify local or state health agencies. No new lesions for 48 hours and a minimum of 72 hours of therapy with no moist, exudative, or draining lesions are required prior to returning to play. These lesions cannot be covered as the sole means of return to play.
Tinea Pedis
Tinea pedis is a common dermatophyte infection involving the feet and is most commonly caused by Trichophyton rubrum. Its distribution is usually interdigital or along the plantar surface of the foot. Topical antifungals with either allylamines or azoles are usually sufficient. Terbinafine has been shown to have a shorter duration of treatment. Athletes with tinea pedis are not restricted from sports participation during treatment, as long as the lesions are properly covered.
