Clinical Trial Controlled Clinical TrialHealing rate and bacterial necrotizing vasculitis in venous leg ulcers.
Morbidity associated with venous leg ulcers is important in the elderly. The biological processes involved during attempts at healing are much more complex than in most models of experimental wounds. In addition, there is still controversy on deleterious effects elicited by both microorganisms and antiseptics on cells involved in the healing process. ⋯ These features were less pronounced in ulcers treated with hydrocolloid+PVP-I. In sum, a broad-spectrum antimicrobial such as PVP-I may be beneficial in reducing deleterious bacteria-related inflammation. As a result, the healing rate leg ulcers is enhanced.

To consider whether oral isotretinoin (Roaccutane/Accutane) represents good value compared with typical alternative treatments for moderate or severe acne. ⋯ The costs and benefits of alternative treatments for acne should be assessed over a period of at least 2 years, preferably longer. The higher initial cost of oral isotretinoin should not be a barrier to its use where the drug is clinically indicated.

Acne vulgaris is a common inflammatory dermatosis capable of producing significant psychological and physical scarring. The following work describes the benefit of using a questionnaire as a clinical tool to identify acne patients who have developed psychological sequelae as a result of the disease process. ⋯ A prospective clinical study examines the early use of isotretinoin in acne and demonstrates the beneficial effect of early therapy in minimising acne scarring. In summary, oral isotretinoin (Roaccutane/Accutane) provides a very effective therapy to prevent acne patients being 'scarred for life'!

C1 inhibitor (C1-INH) deficiency results in bouts of mucocutaneous edema and may be inherited (hereditary angioedema) or acquired (acquired angioedema). The syndrome of acquired angioedema, characterized by the adult onset of angioedema and by the lack of evidence of inheritance of the disease, may be associated with lymphoproliferative or other malignant diseases (type I) or with the presence of autoantibodies to C1-INH (type II); this is a rare variant form of C1-INH deficiency with angioedema. We report here a case of acquired C1-INH deficiency with angioedema, hypotension and abdominal discomfort observed in a 71-year-old man in whom complement abnormalities and autoantibodies against C1-INH have been observed and who was classified as having an autoimmune C1-INH deficiency. From the therapeutic point of view after resolution of the acute attacks, high doses of tranexamic acid have been able, at first, to decrease the frequency and the severity of the symptoms, and subsequently to provide a long symptom-free time.
