Comparative performance of the protocol of plasma rich in growth factors - universal 1 (PRGF-U1) for obtaining platelet rich plasma

Objective: to compare the platelet concentration obtained after application of the protocol of plasma rich in growth factors - universal 1 (PRGF-U1) and the protocol of Anitua and Andia (PRP-A) for obtaining platelet rich plasma. Material and Method: A descriptive, cross-sectional and comparative study was carried out with a simple random probabilistic sample consisting of 16 patients who attended the Periodontics service of the Unit of Second Specialization in Stomatology of the National University of Trujillo. Five blood samples were obtained from each patient, after applying a health questionnaire to rule out any disease or drug consumption, in order to obtain the baseline platelet concentration and that obtained after PRGF-U1 and PRP-A. To compare the platelet concentrations of the two protocols, Student’s t-test was used considering a significance level of p<0.05. RESULTS: The baseline platelet concentration was 371,250 +/- 68,203 platelets/ μL, for PRGF-U1 it was 747,875 +/- 121,645 platelets/μL and for PRP-A it was 595,000 +/- 129,202 platelets/ML. A statistically significant difference (p<0.001) was found between both protocols. Conclusion: The PRGF-U1 protocol yielded a higher platelet concentration compared to the Anitua and Andia protocol.

Estudio retrospectivo de la evolución de las fracturas de meseta tibial tratadas en el Hospital del Lídice / I study retrospective of the evolution of the fractures of tibial plateau tried in the Hospital de Lídice

Se realizó una revisión de 26 pacientes, que fueron tratados en el Hospital General Dr. Jesús Yerena, entre enero de 1997 y diciembre de 2001, por presentar fracturas de mesetas tibiales, quienes fueron resultados ortopédicamente o quirúrgicamente luego de una estancia prolongada de hospitalización, debido a problemas socioeconómicos, y se estudió cual fue la evolución posterior de estos al tratamiento definitivo aplicado. Se obtuvieron resultados que revelaron la importancia de resolver estos casos a la brevedad posible, para reducir el número de aplicaciones inherentes a esta patología altamente incapacitante.
