Bowen's disease (BD) is a form of intraepidermal squamous cell carcinoma, which is clinically characterized by gradually enlarging, well-demarcated erythematous plaques with irregular borders and surface crusting or scaling, affecting primarily the elderly. BD often presents with lesions difficult to treat with standard therapy as surgery, cryosurgery, or 5-fluorouracil (5-FU) for the risk of significantly poor cosmetic outcome, failure rate, and adverse events, related mainly to the age of the patients. Topical PDT with methyl aminolevulinate (MAL) represents a valid and approved therapy for BD lesions in many cases, especially for lesions located at poor healing sites or for large patches of disease, due to its high efficacy coupled with good tolerability and tissue-sparing attitude. In this study, we sought to investigate the efficacy, safety, and cosmetic outcome of MAL-PDT in a series of patients with BD lesions which were challenging to treat for clinical, surgical, and patient-related reasons, such as size of the lesion, difficult surgical approach for anatomical sites, or age of patients and request of the best cosmetic result. We also performed a long-term follow-up to assess recurrence rates and eventual late-onset adverse events.
This proof-of-concept study supports the efficacy of 5% ALA thermosetting gel red-light PDT in inflammatory acne of the face with a relevant clinical improvement of inflammatory lesions with a very good tolerability profile. Clinical improvement was maintained in the medium term (Trial Registration Number: ISRCTN66066651).
Cordylobia sp. is a fly belonging to the Calliphoridae family. Three species of Cordylobia are known: C. anthropophaga, C. rodhaini and C. ruandae. The C. rodhaini Gedoelst 1909 lives in Sub-Saharan Africa, especially in rain forest areas. Usual hosts are rodents and antelopes. Humans are accidentally infested. Myiasis caused by C. rodhaini has been very rarely reported in the literature. We present three cases of C. rodhaini myiasis acquired in Ethiopia and Uganda.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
