RESUMO
BACKGROUND: The availability of intravenous tissue plasminogen activator (IV-tPA) remains limited worldwide, especially in low-income countries, where the burden of disability due to ischemic stroke is the highest. AIMS: To evaluate outcomes and safety of IV-tPA at the only Peruvian reference institute for neurologic diseases. METHODS: We conducted a prospective, observational study of stroke patients who received IV-tPA between 2009 and 2016. We assessed characteristics associated with good outcome (modified Rankine scale 0-2) at 3 months using a multivariate regression model; and factors correlated with clinical improvement (delta National Institute of Health Stroke Scale (NIHSS)) using linear regression. RESULTS: Only 1.98% (39/1,1962) of patients presenting with ischemic stroke received IV-tPA. Nearly half (41%) were younger than 60 years, 56.4 % were men, and most strokes were cardioembolic (46.2%). The majority (64.1%) were treated within 3-4.5 hours. The median NIHSS on admission and discharge was 9 and 4, respectively; 42.1% of patients had an mRS of 0-1 at 3 months. Three patients (7.7%) developed hemorrhagic conversion, and 1 patient died (2.6%). Patients with good outcomes had lower pretreatment systolic blood pressure (138.9 versus 158.1 mm Hg, P < .007), fewer complications during hospitalization (5 versus 9 events, P < .001), shorter hospital stay (14 versus 21 days, P < .03) and, paradoxically, longer last known well -to-door times (148.3 versus 105 minutes, P < .0022). Clinical improvement was associated with shorter door-to-tPA times and obesity. CONCLUSIONS: Our findings indicate that IV-tPA has similar safety and outcomes compared to developed countries. All internal metrics (door-to-tPA, door-to-CT, and CT-to-tPA time) improved over time, highlighting areas for future implementation science studies to further expedite the administration of IV-tPA.

Reversible cerebral vasoconstriction syndrome (RCVS) is an underdiagnosed cause of convexal subarachnoid hemorrhage, characterized by thunderclap headache associated with focal and segmental intracranial vasoconstriction. It can appear complications such as intracerebral hemorrhage, seizures, posterior reversible leukoencephalopathy, or ischemic stroke. Our objective is to present the case of a 51-year-old woman with an RCVS diagnosis, who had a normal digital subtraction angiography at the illness onset. We highlight the high diagnostic value of thunderclap headache and convexal subarachnoid hemorrhage. We also highlight the importance of repeating the angiographic studies in the second week when there is strong diagnostic suspicion.
RESUMO
INTRODUCTION: Educational interventions can raise awareness and understanding in population groups and may help to achieve changes in behavior. OBJECTIVE: To determine if the educational handwashing program applied to high-school students reduces the colonization of infectious bacteria on the hands. METHODS: A non-randomized quasi-experimental study was carried out using consecutive sampling of the students of the last year of high-school who were divided into an intervention group and a control group. Data were obtained before and after the implementation of the educational program. Samples were taken from the dominant hand for bacterial culture, and a questionnaire was applied that assessed knowledge of hand hygiene before and after the program. The program was aimed at improving the level of understanding and attitudes of students regarding hand hygiene. RESULTS: Of 208 samples obtained, the most frequent agents before and after the educational program were Staphylococcus epidermidis (39% versus 23%) and Staphylococcus aureus (21% versus 15%). The average number of colonies was 236 and 183 respectively (p = 0.35). CONCLUSION: The educational program managed to improve the level of understanding about hand hygiene; however, it was not enough to reduce bacterial colonization, so other behaviors such as direct supervision should be considered.
INTRODUCCIÓN: La intervención en poblaciones por medio de programas educativos logra aumentar el conocimiento en un determinado grupo y además, en algunos casos, se logra un cambio de conducta. OBJETIVO: Determinar si el programa educativo de lavado de manos aplicado a los estudiantes de educación secundaria reduce la colonización de bacterias infecciosas en las manos. METODOLOGÍA: Se realizó un estudio cuasi experimental no aleatorizado mediante muestreo consecutivo a los alumnos del último año de secundaria, quienes fueron divididos en dos grupos de intervención y control, analizados en dos etapas antes y después de la aplicación del programa educativo. Se tomaron las muestras de la mano dominante para el cultivo bacteriano. Además, se aplicó un cuestionario que evaluó los conocimientos sobre higiene de manos antes y después de la aplicación del programa, que estuvo dirigido a mejorar el nivel de conocimiento y de las actitudes de los estudiantes en relación a la higiene de manos. RESULTADOS: De 208 muestras obtenidas los agentes más frecuentes antes y después de la aplicación del programa educativo fueron Staphylococcus epidermidis (39% versus 23%) y Staphylococcus aureus (21%versus15%); el promedio del número de colonias fue 236 y 183 respectivamente (p = 0,35). CONCLUSIÓN: La aplicación del programa educativo logró mejorar el nivel de conocimiento sobre la higiene de manos. Sin embargo, no fue suficiente para reducir la colonización bacteriana, por lo que debería agregarse otras conductas como la supervisión directa.

Se presentan los 9 primeros casos de cáncer avanzado de esófago tratados mediante la combinación de interferón alfa leucocitario más radioterapia; 8 de los pacientes presentaron carcinoma epidermoide del esófago y 1 adenocarcinoma recidivante. Este tratamiento logró la regresión de la disfagia y obtuvo mejoría clínica y radiológica en todos los pacientes. De los 9 pacientes, 3 fallecieron hasta el 30 de octubre, 1 de los cuales fue en el transcurso del tratamiento con radioterapia, por una trombosis pulmonar diseminada con muy mal estado general, que se diagnosticó en la necropsia. Los resultados preliminares hacen plantear que ante estos casos avanzados, esta modalidad terapéutica puede constituir un arma más en el tratamiento de dicha afección. El estudio planteado con un mayor número de casos permitirá conclusiones más valederas a largo plazo
