Clinicians should be aware of the development of tachyphylaxis to superpotent topical steroids, which can occur as early as treatment selleckbio day 4. Recovery occurs after several days of rest, which has led to alternating courses of therapy such as 3 days on, 4 days off, or 1 week on, 1 week off. Topical steroid treatment should be continued until resolution of the acute phase of illness. Our practice is to prescribe betamethasone valerate 0.1% cream every 12 hours to the vulva externally and betamethasone valerate 0.1% ointment every 12 hours to the internal vaginal mucosa via a Milex dilator (discussed below). Regular application of antifungal creams can be used as well, as even short courses of intravaginal steroids can predispose to moniliasis.

Although nearly half of the overall mortality from TEN is attributed to infection, it is unlikely that systemic absorption of topical steroids increases the risk of sepsis in these patients. 2 As such, the initiation of steroid therapy should occur at the time of diagnosis, and an effort must be made to familiarize medical staff with the importance of early intervention. Alternatively, intravaginal tacrolimus 0.1%, a calcineurin-inhibitor, has been reported to be successful in preventing vaginal stenosis in erosive lichen planus.24 The use of tacrolimus in SJS and TEN has not been studied, however. Oral therapy with corticosteroids and other immunosuppressive agents such as cyclosporine, azathioprine, mycophenolate mofetil, and etanercept has been reserved for progressive disease.

24 Vaginal Molds to Disrupt Adhesion Formation In addition to topical steroids, a soft vaginal mold should be placed prophylactically as early as possible during the acute phase of illness and used regularly until complete healing of ulcerative lesions has occurred. Our group recommends Milex vaginal dilators (Milex Products Inc., Chicago, IL). These dilators are made of latexfree, hypoallergenic silicone and come in various lengths and widths. They are available for purchase from online distributors (CooperSurgical, Trumbull, CT). If such dilators are not immediately available, a condom filled with foam rubber or an inflatable vaginal dilator could be used for this purpose. Another option is the intermittent use of a hard vaginal dilator such as a Syracuse Medical dilator (Syracuse, NY).

Regular and early use of dilator therapy is important to maintain a functional vaginal caliber and length. The mold can be coated with topical steroids and used until clinical resolution. GSK-3 Patients can be instructed to wear the molds for 24 hours per day, removing them only for cleansing, medication application, and toileting. For a more minimalist approach, daily insertion and removal is an option for those who find leaving the dilator in place overnight unacceptable. Early intercourse after wound epithelialization may also help reduce the incidence of stenosis.
