Laser terapia en el manejo de aftas mayores: reporte de un caso / Laser therapy in the management of major afthas: case report

Las lesiones ulcerativas, como las Aftas pueden originarse por múltiples factores y afectar la masticación, nutrición, deglución, fonación y la estética. Dentro de los tratamientos se sugiere el uso de fármacos antibióticos, antivirales, anestésicos tópicos y medidas locales paliativas. Se presenta caso de un paciente masculino de 34 años, sin antecedentes médicos relevantes, con diagnostico de estomatitis aftosa recurrente desde los 8 años; inicialmente aftas menores, después las lesiones aumentaron en tamaño. Con antecedentes de tratamientos antivirales, antibióticos, antimicóticos, sin evolución satisfactoria. Al examen estomatológico se observan múltiples ulceras en carrillos, piso de boca, dorso y superficie ventral de lengua. Se decide tratamiento con Láser de alta y baja potencia para terapia de barrido en zonas intraorales y sobre puntos de acupuntura; obteniendo cicatrización de las lesiones y disminución de la sintomatología. El uso de la terapia láser es una propuesta innovadora, indolora y satisfactoria mediante la cual se pueden combinar los beneficios del laser de alta y baja potencia para generar efectos analgésicos y cicatrizantes

Ulcerative lesions, such as canker can be caused by many factors and affect chewing, nutrition, swallowing, speech and aesthetics. Within treatments suggest the use of antibiotic drugs, antivirals, local anesthetics and local palliative measures. A case report of a male patient of 34 years, with no relevant medical history, with a diagnosis of recurrent aphthous stomatitis from 8 years, initially under thrush after injuries increased in size. With a history of antiviral treatments, antibiotics, antifungals, with no satisfactory outcome. Stomatological examination were multiple ulcers in cheek, floor of mouth, back and ventral surface of tongue laser treatment is decided high-and low-power scanning therapy in intraoral areas and acupuncture points, achieved healing in wounds and reducing pain. The use of laser therapy is an innovative, painless and successful through which you can combine the benefits of high and low laser power to generate analgesic and healing

Vaccination with SPf66, a chemically synthesised vaccine, against Plasmodium falciparum malaria in Colombia.

Preclinical and clinical studies have established the safety and immunogenicity of the chemically synthesised SPf66 malaria vaccine. The present study is a phase III randomised, double-blind, placebo-controlled, efficacy trial completed in La Tola, Colombia. 1548 volunteers over one year of age received three doses of either the vaccine (n = 738) or placebo (n = 810). Active and passive case detection methods were used to document clinical episodes of malaria among the study population. The follow-up period began one month after the third dose and lasted for one year. 168 and 297 episodes of Plasmodium falciparum malaria were documented in the SPf66 group and the placebo group, respectively; this corresponds to a crude protective efficacy of 38.8%. Incidence rates for first or only P falciparum malarial episodes were 22.3% per annum among the vaccinee group and 33.5% among the placebo group (RR = 1.5; 95% Cl 1.23, 1.84). Therefore, the protective efficacy of SPf66 against first or only episodes was 33.6% (95% Cl 18.8, 45.7), being highest in children aged 1-4 years (77%) and adults older than 45 years (67%). The estimated protective efficacy against second episodes was 50.5% (95% Cl 12.9-71.9). Our study shows that the chemically synthesised SPf66 malaria vaccine is safe, immunogenic, and protective against P falciparum malaria in semi-immune populations subject to natural challenge.
