Low-dose high-dose-rate brachytherapy in the treatment of facial lesions of cutaneous T-cell lymphoma
BACKGROUND: The use of many of the standard skin-directed mycosis fungoides (MF) therapies on facial skin may be limited by site-specific increased risks of side effects, excessive inflammation, and ocular toxicity. OBJECTIVE: Our study aimed to describe the levels of erythema, scale, and induration of facial lesions in MF before and after low-dose high-dose-rate surface applicator brachytherapy and to examine the overall clinical response to brachytherapy. METHODS: A total of 23 facial MF lesions in 10 patients were treated with high-dose-rate brachytherapy doses of 4 Gy per session for a total of 2 fractions at our multidisciplinary cutaneous oncology clinic between August 17, 2009, and March 12, 2012. RESULTS: In all 23 lesions, dramatic clinical improvement was observed. Patients were followed up for a median of 6.3 months. No recurrences were reported in the follow-up period. LIMITATIONS: Long-term follow-up is lacking. Reassessment of all included patients at annual intervals for a period of at least 5 years is the authors' goal. CONCLUSION: Low-dose high-dose-rate brachytherapy using custom-made surface molds is a highly efficacious therapy in the treatment of facial lesions in MF
Pediatric Contact Dermatitis Registry Inaugural Case Data
Little is known about the epidemiology of allergic contact dermatitis (ACD) in US children. More widespread diagnostic confirmation through epicutaneous patch testing is needed.
The aim was to quantify patch test results from providers evaluating US children.
The study is a retrospective analysis of deidentified patch test results of children aged 18 years or younger, entered by participating providers in the Pediatric Contact Dermatitis Registry, during the first year of data collection (2015-2016).
One thousand one hundred forty-two cases from 34 US states, entered by 84 providers, were analyzed. Sixty-five percent of cases had one or more positive patch test (PPT), with 48% of cases having 1 or more relevant positive patch test (RPPT). The most common PPT allergens were nickel (22%), fragrance mix I (11%), cobalt (9.1%), balsam of Peru (8.4%), neomycin (7.2%), propylene glycol (6.8%), cocamidopropyl betaine (6.4%), bacitracin (6.2%), formaldehyde (5.7%), and gold (5.7%).
This US database provides multidisciplinary information on pediatric ACD, rates of PPT, and relevant RPPT reactions, validating the high rates of pediatric ACD previously reported in the literature. The registry database is the largest comprehensive collection of US-only pediatric patch test cases on which future research can be built. Continued collaboration between patients, health care providers, manufacturers, and policy makers is needed to decrease the most common allergens in pediatric consumer products
