Ethambutol-induced toxic epidermal necrolysis.

Toxic epidermal necrolysis (TEN) is a severe cutaneous reaction that most commonly is related to drug exposure and that clinically can be confused with other bullous dermatoses, particularly staphylococcal scalded skin syndrome (SSSS) and erythema multiforme major (the Stevens-Johnson syndrome). We report the first case, to our knowledge, of TEN associated with ethambutol hydrochloride administration. Toxic epidermal necrolysis can be partially differentiated from other bullous dermatoses by history and clinical presentation.

Two outbreaks of sternal wound infection due to organisms of the Mycobacterium fortuitum complex.

Two outbreaks of postoperative wound infections due to organisms of the Mycobacterium fortuitum complex (Mycobacterium chelonei and M. fortuitum) occurred among patients who underwent open-heart surgery. In one hospital, 19 of 80 patients who underwent cardiac surgery within a 10-week period developed sternal infection with M.

Mycobacterium fortuitum epidemics after open-heart surgery.

We present the clinical and epidemiological features of Mycobacterium fortuitum epidemics involving 19 patients who underwent open-heart surgery. The source of the infection could not be identified. However, bone wax and homografts utilized at that time have been suspected.
