Efectividad del lisado plaquetario en la cicatrización de las fisuras anales / Effectiveness of platelet lysate in anal fissures cicatrization

Introducción: las fisuras anales son un problema de salud importante en la población cubana, incluso con la supresión de los factores desencadenantes, muchas de ellas tienden a la cronicidad; su evolución es tórpida, y es elevado el riesgo de complicación de las mismas. Objetivo: evaluar la cicatrización de las fisuras anales mediante lisado plaquetario en el Hospital General Docente Comandante Pinares de San Cristóbal. Método: se realizó un estudio cuasi experimental en el servicio de cirugía general del Hospital General Docente Comandante Pinares desde enero 2015 hasta junio 2017. Se incluyeron en el estudio todos los pacientes adultos, de ambos sexos, atendidos por el diagnóstico de fisura anal con inadecuada respuesta al tratamiento convencional y sin otras enfermedades de base que impidieran el uso de la terapia regenerativa. A todos los pacientes se les solicitó el consentimiento informado previa explicación de las características del estudio. Resultados: la hemorroidectomía fue el proceder más frecuente asociado a las fisuras anales. El dolor fue el síntoma predominante antes del tratamiento. La reducción del área de la fisura fue evidente en los tratados con lisado. El efecto final en los pacientes tratados con el método fue positivo. Conclusiones: se comprobó que el lisado plaquetario usado para la cicatrización de la fisura anal crónica fue efectivo con un resultado de satisfacción por parte de los pacientes, con un mínimo de reacciones adversas. Puede representar un futuro promisorio en el tratamiento de esta enfermedad(AU)

Introduction: Anal fissures are an important health problem in the Cuban population, even with the suppression of the triggering factors, many of them tend to chronicity; its evolution is torpid, and their risk for complication is high. Objective: To evaluate the healing of anal fissures by platelet lysate in Comandante Pinares General Teaching Hospital in San Cristóbal. Method: A quasi-experimental study was performed in the general surgery service of Comandante Pinares General Teaching Hospital, from January 2015 to June 2017. All adult patients, of both sexes, were attended upon diagnosis of anal fissure and were included in the study. with inadequate response to conventional treatment and without other underlying diseases that could prevent the use of regenerative therapy. All patients were asked for their informed consent prior explanation of the study characteristics. Results: Hemorrhoidectomy was the most frequent procedure associated with anal fissures. Pain was the predominant symptom before treatment. The reduction in the area of ​​the fissure was evident in those patients treated with the lysate. The final effect in patients treated with the method was positive. Conclusions: The usage of the platelet lysate for the healing of chronic anal fissure proved effective, with a result of patient satisfaction, with a minimum of adverse reactions. It may represent a promising future in the treatment of this disease(AU)

Impact of autologous whole blood administration upon experimental mouse models of acute Trypanosoma cruzi infection

Background: Autologous whole blood (AWB) administration is described as alternative/complementary medical practice widely employed in medical and veterinary therapy against infections, chronic pathologies and neoplasias. Our aim is to investigate in vivo biological effect of AWB using healthy murine models under the course of Trypanosoma cruzi acute infection. Methods: The first set of studies consisted of injecting different volumes of AWB and saline (SAL) into the posterior region of quadriceps muscle of healthy male Swiss mice under distinct therapeutic schemes evaluating: animal behavior, body and organ weight, hemogram, plasmatic biochemical markers for tissue damage and inflammatory cytokine levels and profile. To assess the impact on the experimental T. cruzi infection, different schemes (prior and post infection) and periods of AWB administration (from one up to 10 days) were conducted, also employing heterologous whole blood (HWB) and evaluating plasma cytokine profile. Results: No major adverse events were observed in healthy AWB-treated mice, except gait impairment in animals that received three doses of 20 L AWB in the same hind limb. AWB and SAL triggered an immediate polymorphonuclear response followed by mononuclear infiltrate. Although SAL triggered an inflammatory response, the kinetics and intensity of the histological profile and humoral mediator levels were different from AWB, the latter occurring earlier and more intensely with concomitant elevation of plasma IL-6. Inflammatory peak response of SAL, mainly composed of mononuclear cells with IL-10, was increased at 24 h. According to the mouse model of acute T. cruzi infection, only minor decreases ( 30%) in the parasitemia levels were produced by AWB and HWB given before and after infection, without protecting against mortality. Rises in IFN-gamma, TNF-alpha and...

Rotura prematura de membranas ovulares: tratamiento con parche hemático transvaginal endocervical autólogo: presentación de un caso / Premature rupture of membranes: treatment with autologous endocervical transvaginal blood patch: case report

Se trata de una primigesta de 34 años de edad, quien presentó rotura prematura de membranas ovulares espontánea a las 24 semanas de gestación. Luego de realizar el diagnóstico clínico, microscópico y ecográfico de la entidad y descartando la presencia de infección, se decide la colocación de un parche hemático transvaginal endocervical autólogo como tratamiento de la presentó rotura prematura de membranas ovulares espontánea. La paciente evoluciona afebril con recuperación del líquido amniótico al sexto día del procedimiento. Inicia a las 35 semanas contracciones uterinas espontáneas dolorosas y al verificar en el monitoreo fetal intraparto un patrón compatible con desaceleración variable se decide la realización de una cesárea segmentaria obteniendo así un recién nacido pretérmino de 1550 g y 52 cm con evolución satisfactoria. El parche hemático transvaginal endocervical autólogo ofrece una alternativa como tratamiento de la presentó rotura prematura de membranas ovulares espontánea

This is the case of a 34-year-old primigravida who introduced spontaneous preterm premature rupture of membranes to 24 weeks of gestation. Then after clinical, microscopic, ultrasound diagnosis and discarding infection, we selected of a transvaginal endocervical autologous blood patch as the spontaneous preterm premature rupture of membranes treatment. The patient evolves without fever with the amniotic fluid recovery to the sixth day of the procedure. Start 35 weeks painful spontaneous uterine contractions and by verifying fetal monitoring intrapartum support Variable Deceleration Pattern is decided segment caesarean section giving a new born preterm 1550 g and 52 cm with satisfactory evolution. The transvaginal endocervical autologous blood patch offers an alternative to the spontaneous preterm premature rupture of membranes treatment
