The anterior cruciate ligament has been and is of great interest to scientists and orthopaedic surgeons worldwide. Anterior cruciate ligament reconstruction was initially performed using an open approach. When the approach changed from open to arthroscopic reconstruction, a 2- and, later, 1-incision technique was applied. With time, researchers found that traditional arthroscopic single-bundle reconstruction did not fully restore rotational stability of the knee joint and a more anatomic approach to reconstruct the anterior cruciate ligament has been proposed. Anatomic anterior cruciate ligament reconstruction intends to replicate normal anatomy, restore normal kinematics, and protect long-term knee health. Although double-bundle anterior cruciate ligament reconstruction has been shown to result in better rotational stability in both biomechanical and clinical studies, it is vital to differentiate between anatomic and double-bundle anterior cruciate ligament reconstruction. The latter is merely a step closer to reproducing the native anatomy of the anterior cruciate ligament; however, it can still be done nonanatomically. To evaluate the potential benefits of reconstructing the anterior cruciate ligament in an anatomic fashion, accurate, precise, and reliable outcome measures are needed. These include, for example, T2 magnetic resonance imaging mapping of cartilage and quantification of graft healing on magnetic resonance imaging. Furthermore, there is a need for a consensus on which patient-reported outcome measures should be used to facilitate homogeneous reporting of outcomes.
Colombian patients with New World cutaneous leishmaniasis were treated with a combination of a topical formulation (15% paromomycin sulfate/5% methylbenzethonium chloride, twice a day) and parenteral meglumine antimonate (20 mg of antimony [Sb]/kg.d]). Cohort 1 received topical therapy for 10 days and Sb for 7 days; 18 (90%) of the 20 patients were cured (follow-up, 12 months). Other clinical data suggested that neither the topical formulation alone nor the 7-day regimen of Sb alone would have cured many patients. In a subsequent cohort, which received topical therapy for 10 days and Sb for 3 days, the cure rate was 42% (eight of 19 patients). In Colombian cohorts (historical controls) treated with Sb alone for 10-15 days, the cure rate was 31%-36%. Side effects in cohort 1 patients consisted of local reactions to the topical formulation: burning and pruritus in 25% of patients and vesicle formation in 15% of patients. This is the first report that a regimen partially composed of topical antimicrobial agents can be highly effective for treatment of New World cutaneous leishmaniasis.
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.
