Medical Problems of the Swimmer

Aquatic sports dermatoses: part 1. In the water: freshwater dermatoses

The first of this three-part series on water-related dermatoses involving the athlete will include sports occurring with the majority of time spent in the water. These sports include swimming, diving, scuba, snorkeling and water polo. Numerous authors have described dermatologic conditions commonly seen in swimmers. This series provides an updated and comprehensive review of these water dermatoses. In order to organize the vast number of skin conditions related to water exposure, we divided the skin conditions into groupings of infectious and organism-related dermatoses, irritant and allergic dermatoses and miscellaneous dermatoses. The vast majority of skin conditions involving the water athlete result from chemicals and microbes inhabiting each environment. When considering the effects of swimming on one's skin, it is also useful to differentiate between exposure to freshwater (lakes, ponds and swimming pools) and exposure to saltwater. This review will serve as a guide for dermatologists, sports medicine physicians and other medical practitioners in recognition and treatment of these conditions.

Ear problems in swimmers

Acute diffuse otitis externa (swimmer's ear), otomycosis, exostoses, traumatic eardrum perforation, middle ear infection, and barotraumas of the inner ear are common problems in swimmers and people engaged in aqua activities. The most common ear problem in swimmers is acute diffuse otitis externa, with Pseudomonas aeruginosa being the most common pathogen. The symptoms are itching, otalgia, otorrhea, and conductive hearing loss. The treatment includes frequent cleansing of the ear canal, pain control, oral or topical medications, acidification of the ear canal, and control of predisposing factors. Swimming in polluted waters and ear-canal cleaning with cotton-tip applicators should be avoided. Exostoses are usually seen in people who swim in cold water and present with symptoms of accumulated debris, otorrhea and conductive hearing loss. The treatment for exostoses is transmeatal surgical removal of the tumors. Traumatic eardrum perforations may occur during water skiing or scuba diving and present with symptoms of hearing loss, otalgia, otorrhea, tinnitus and vertigo. Tympanoplasty might be needed if the perforations do not heal spontaneously. Patients with chronic otitis media with active drainage should avoid swimming, while patients who have undergone mastoidectomy and who have no cavity problems may swim. For children with ventilation tubes, surface swimming is safe in a clean, chlorinated swimming pool. Sudden sensorineural hearing loss and some degree of vertigo may occur after diving because of rupture of the round or oval window membrane.

Dermatologic disorders of the athlete

The most common injuries afflicting the athlete affect the skin. The list of sports-related dermatoses is vast and includes infections, inflammatory conditions, traumatic entities, environmental encounters, and neoplasms. It is critical that the sports physician recognises common and uncommon skin disorders of the athlete. Knowledge of the treatment and prevention of various sports-related dermatoses results in prompt and appropriate care of the athlete. Infections probably cause the most disruption to individual and team activities. Herpes gladiatorum, tinea corporis gladiatorum, impetigo, and furunculosis are sometimes found in epidemic proportions in athletes. Vigilant surveillance and early treatment help teams avoid these epidemics. Fortunately, several recent studies suggest that pharmacotherapeutic prevention may be effective for some of these sports-related infections. Inflammatory cutaneous conditions may be banal or potentially life threatening as in the case of exercise-induced anaphylaxis. Athletes who develop exercise-induced anaphylaxis may prevent outbreaks by avoiding food before exercise and extreme temperatures while they exercise. Almost all sports enthusiasts are at risk of developing traumatic entities such as nail dystrophies, calluses and blisters. Other more unusual traumatic skin conditions, such as talon noire, jogger's nipples and mogul's palm, occur in specific sports. Several techniques and special clothing exist to help prevent traumatic skin conditions in athletes. Almost all athletes, to some degree, interact with the environment. Winter sport athletes may develop frostbite and swimmers in both fresh and saltwater may develop swimmer's itch or seabather's eruption, respectively. Swimmers with fair skin and light hair may also present with unusual green hair that results from the deposition of copper within the hair. Finally, athletes are at risk of developing both benign and malignant neoplasms. Hockey players, surfers, boxers and football players can develop athlete's nodules. Outdoor sports enthusiasts are at greater risk of developing melanoma and non-melanoma skin cancer. Athletes spend a great deal of time outdoors, typically during peak hours of ultraviolet exposure. The frequent use of sunscreens and protective clothing will decrease the athlete's sun exposure. It is critical that the sports physician recognises common and uncommon skin disorders of the athlete. Knowledge of the treatment and prevention of various sports-related dermatoses results in prompt and appropriate care of the athlete.

Swimming injuries and illnesses

Swimming has a distinct profile of injuries and medical conditions. Common problems seen among swimmers include 'swimmer's shoulder,' an overuse injury that causes inflammation of the supraspinatus and/or the biceps tendon; overuse injuries of the elbow, knee, ankle, and back; medical conditions such as asthma, folliculitis, and otitis externa; and problems associated with overtraining. Swimmers are more likely to comply with treatment plans that minimize time spent out of the water. Prevention and treatment of musculoskeletal injuries often focus on proper stroke mechanics.

Grommets, swimming and otorrhoea--a review

Ever since Armstrong reintroduced the concept of grommet insertion parents have been asking 'may my child swim?', yet there is still no consensus as to the correct answer. This paper reviews the work that has been done on this subject in the last 25 years. A review of the rates of otorrhoea following grommet insertion, irrespective of swimming, shows a variation from 12 to 64 per cent. Evidence suggests that pressures of 12-23 cm H2O are needed to push water through a grommet and that it is unlikely that water will enter the middle ear during surface swimming. Only bath water seems to cause significant inflammatory changes to middle ear mucosa. Not a single paper comparing swimmers with non-swimmers shows an increased rate of otorrhoea in those patients who swam; to the contrary, rates of otorrhoea were repeatedly higher in those patients who did not swim. The evidence suggests that swimming without ear protection can be safely permitted for children with grommets.

Evaluation for waterproof ear protectors in swimmers

The middle ear cavity is exposed and vulnerable to waterborne infection in patients with grommets, perforated tympanic membranes and after radical mastoidectomy. Patients suffering from chronic otitis externa and those receiving radiotherapy to the head and neck also have an increased susceptibility to such infections. Many advocate the use of waterproof ear protectors in such patients when swimming. The choice of a suitable ear protector is complicated as many are now available commercially. This study was therefore designed to evaluate the degree of protection afforded by seven different ear protectors in a group of six swimmers. A very sensitive, original method of water detection was devised incorporating a pH indicator strip. The results showed conclusively that cotton wool coated in paraffin jelly BPC was the most effective method of ear protection and was found to be comfortable and easy to use. Other methods, including custom-made silicone rubber plugs, were not adequate in sealing the external auditory canal and are considerably more expensive.
