RESUMO

ABSTRACT Objectives: To estimate the risk of post-vasectomy infections in various settings and across various surgical techniques and sanitization practices. Patients and Methods: Retrospective review of the records of 133,044 vasectomized patients from four large practices/network of practices using the no-scalpel vasectomy (NSV) technique in Canada (2011-2021), Colombia (2015-2020), New Zealand (2018-2021), and the United Kingdom (2006-2019). We defined infection as any mention in medical records of any antibiotics prescribed for a genital or urinary condition following vasectomy. Results: Post-vasectomy infection risks were 0.8% (219 infections/26,809 procedures), 2.1% (390/18,490), 1.0% (100/10,506), and 1.3% (1,007/77,239) in Canada, Colombia, New Zealand, and the UK, respectively. Audit period comparison suggests a limited effect on the risk of infection of excising a short vas segment, applying topical antibiotic on scrotal opening, wearing a surgical mask in Canada, type of skin disinfectant, and use of non-sterile gloves in New Zealand. Risk of infection was lower in Colombia when mucosal cautery and fascial interposition [FI] were used for vas occlusion compared to ligation, excision, and FI (0.9% vs. 2.1%, p<0.00001). Low level of infection certainty in 56% to 60% of patients who received antibiotics indicates that the true risk might be overestimated. Lack of information in medical records and patients not consulting their vasectomy providers might have led to underestimation of the risk. Conclusion: Risk of infection after vasectomy is low, about 1%, among international high-volume vasectomy practices performing NSV and various occlusion techniques. Apart from vasectomy occlusion technique, no other factor modified the risk of post-vasectomy infection.

RESUMO

Los hemangiomas capilares son lesiones tumorales benignas comunes en diferentes localizaciones. Sin embargo la afección del sistema central es extremadamente inusual. En la literatura tan solo han sido reportados 7 casos de hemangiomas capilares de localización exclusiva intramedular y poco más de 20 casos con compromiso extramedular adicional. Reportamos un paciente adolescente alteración motora y sensitiva progresivo del miembro superior izquierdo asociado a cervicalgia y espasmos musculares cervicales. La resonancia magnética reveló la presencia de una lesión medular cervical sugestiva de neoplasia con un importante componente vascular. Durante la resección no se observó compromiso extra-medular. Los exámenes histopatológico e inmunohistoquímico confirmaron el diagnostico de hemangioma capilar. Si bien, se han publicado muy pocos casos de hemangiomas capilares intramedulares, se cree que puede existir un importante subregistro. En general constituyen una patología benigna de buen pronóstico y que no requiere de manejos adyuvantes como quimio o radioterapia, pero si de un seguimiento neurológico.

RESUMO

Objetivo: determinar la concordancia entre observadores para medir la función de sensibilidad al contraste empleando el test CSV 1000E en un grupo de infantes entre los siete a diez años. Metodología: fueron evaluados cincuenta niños (cien ojos) visualmente sanos empleando el CSV 1000E. Cada infante fue evaluado por dos evaluadores el mismo día con una diferencia de 30 minutos entre evaluaciones. Resultados: la curva de sensibilidad al contraste promedio fue normal, aunque superior hacia las frecuencias espaciales altas, al ser comparada con un estudio similar (López, 2003). La concordancia obtenida fue muy pobre –coeficiente de correlación concordancia de Lin (pc<0.90)– para todas las frecuencias espaciales, debido a la falta de precisión del test; los límites de acuerdo fueron más amplios a los publicados en otra investigación (Pomerance & Evans, 1994). Conclusiones: los resultados encontrados muestran que el test tiene una baja concordancia, lo que indicaría una pobre validez para medir la función de sensibilidad al contraste en niños.


The purpose of this trial was determinate the test retest reliability between evaluators to measurement contrast sensitivity function using the CSV 1000E test in children between 7-10 years. Methods: fifty visually-healthy children were tested using the CSV1000E. Each children was seen by 2 evaluators the same day, thirty minutes apart from each evaluations. Results: the contrast sensitivity curve function was normal, although it was higher for high spatial frequencies when compared to that was it found in another trial (López, 2003). test retest reliability was poor (pc<0.90) for all spatial frequencies because the CSV 1000 precision was low, 95 por ciento limits of agreement were wider than found in another research project (Pomerance y Evans, 1994). Conclusions: the results have shown that CSV 1000 had low agreement, means this test has poor reliability to assess contrast sensitivity function in children.
