RESUMO

INTRODUCTION: The extensor digitorum brevis manus (EDBM) is an accessory muscle of the dorsum of the hand that may appear as a painful mass. It is treated surgically, usually by excision of the muscle. CASE REPORT: 14-year-old male with bilateral painful masses on the dorsal aspect of his hands. Ultrasound confirmed the diagnosis of EDBM. Due to the associated symptoms, decision was made to conduct surgical treatment with resection of both muscle masses. DISCUSSION: EDBM is an infrequent cause of wrist pain, especially in children and adolescents. Surgical treatment has proven to have a significant impact on the improvement of the symptoms suffered by these patients.

RESUMO

BACKGROUND: The aims are to evaluate the morphometry of the sellar region and propose a safety window on the floor of the sella turcica for the transsphenoidal approach in a Hispanic population. MATERIALS AND METHODS: We retrospectively analysed 150 computed tomographic angiography sellar region images from asymptomatic patients. The images were evaluated intraobservatory by an expert radiologist. We measured: intercarotid distance of cavernous segment; depth of sella turcica; skull base angle; anterior distance, the distance between anterior spinal nasal and floor of the sella turcica; posterior distance, the distance between anterior spinal nasal and posterior wall of the sella turcica; anterior surgical angle, formed between the floor of the nostril and superior limit of the anterior wall of the sella turcica; and posterior angle, formed between the floor of the nostril and the inferior limit of the posterior wall of the sella turcica. RESULTS: Safety window was based on two measures: the intercarotid distance and depth. The mean of the safety window is 151.13 mm² and 147.60 mm² for men and women, respectively. The intercarotid distance was 17.83 mm. The depth of the sella turcica was 8.46 mm. The skull base angle was 112.13 grades. The anterior distance was 76.34 mm. The posterior distance was 87.59 mm. The anterior surgical angle was 32.76 grades. The posterior surgical angle was 87.59 grades. CONCLUSIONS: The surgical approach space is smaller in females. It could significate a more complicated surgery in this population. Anatomical understanding could reduce complications in hospitals without a neuronavigation system.

RESUMO

BACKGROUND: The study of the tentorial notch can improve the understanding of brain injury mechanisms. Tentorial morphology has been analysed primarily in cadaveric studies. However, the postmortem effect can cause variability in the measurements. The objective was to evaluate the morphometry of the tentorial notch and the third cranial nerve on living subjects using magnetic resonance imaging (MRI). MATERIALS AND METHODS: A retrospective cross-sectional study was performed. Using consecutive cases, 60 MRI scans were analysed for tentorial notch morphology. Maximum notch width (MNW), notch length (NL), interpedunculoclival (IC) distance, apicotectal (AT) distance, third cranial nerve (CN-III) distance, and inter- CN-III angle, were obtained. For the classification of the tentorial notch quartile distribution technique for MNW, NL, AT distance, and IC distance were used. RESULTS: According to the quartile of the MNW, patients were stratified into narrow, midrange, and wide groups. Using the NL quartile groups, they were also classified as short, midrange, and long. With these, the tentorial notch could be classified into eight types. Statistical differences between genders in the MNW and inter-CN-III angle were found, as well as a strong positive correlation between NL and AT distance, and between right and left CN-III distances. CONCLUSIONS: There were differences between the cadaveric samples and living subjects in the CN-III distances. This difference could be explained by the dehydration of brain volume in the postmortem process which may cause nerve elongation. Morphometry of the tentorial notch and its neurovascular relations allows a better understanding of the mechanisms of brain herniation.

RESUMO

OBJECTIVES: The treatment of keloid scars is based on multiple lines of therapy, with varying levels of efficacy(1), and there is currently no single treatment that guarantees cure and prevents recurrence. In the pediatric population, the treatments used are not standardized, and there is insufficient evidence to support efficacy and complications. The objective of this study was to analyze the patients who required brachytherapy as an adjuvant to surgical resection in recurrent keloid scars. MATERIALS AND METHODS: A retrospective analysis of patients diagnosed with keloids and undergoing adjuvant brachytherapy in our institution was carried out, while assessing efficacy and implementation in our treatment protocol for keloid scarring. RESULTS: After various therapeutic lines, 4 patients aged 9-17 years old with recurrent keloid scars around the ear and eligible for adjuvant brachytherapy - administered after surgical resection, in two sessions - were studied and followed up for up to 18-21 months. CONCLUSIONS: Despite our limited experience in the use of adjuvant brachytherapy, the results obtained to date support its efficacy, as reported in the literature. We therefore consider its inclusion in the treatment of keloid scars that have recurred after other treatments to be appropriate.


OBJETIVOS: El tratamiento de las cicatrices queloideas se basa en múltiples líneas terapéuticas, con diferentes niveles de eficacia(1), sin existir actualmente un tratamiento que garantice su curación y prevenga su recurrencia. En la población pediátrica los tratamientos empleados no están estandarizados y no hay evidencia suficiente que avale su eficacia y sus complicaciones. Este trabajo tiene como objetivo analizar los pacientes que han precisado braquiterapia coadyuvante a la resección quirúrgica en cicatrices queloideas recidivantes. MATERIAL Y METODOS: Análisis retrospectivo de los pacientes diagnosticados en nuestro centro de cicatriz queloidea, en los que se realizó braquiterapia coadyuvante, valorando su eficacia y su implementación en nuestro protocolo de tratamiento de la cicatriz queloidea. RESULTADOS: Se estudiaron 4 pacientes entre 9-17 años con cicatrices queloideas a nivel auricular, recidivantes a varias líneas terapéuticas, que fueron candidatos para el uso de braquiterapia coadyuvante, administrada posterior a la resección quirúrgica, en dos sesiones, se realizó seguimiento hasta 18-21 meses. CONCLUSIONES: A pesar de nuestra limitada experiencia en el uso de la braquiterapia coadyuvante, los resultados obtenidos hasta la fecha avalan su eficacia, de acuerdo con lo publicado en la literatura. Consideramos adecuada su inclusión en el tratamiento de cicatrices queloideas recidivantes a otros tratamientos.

RESUMO

INTRODUCTION: Acute appendicitis is the most frequent cause of acute abdomen in children. The objective of this study was to analyze the causes, approach, and results of complications requiring surgery following appendectomy. MATERIAL AND METHODS: A retrospective study of the appendectomies conducted in three third-level institutions from 2015 to 2019 was carried out. Complications, causes, and number of re-interventions, time from one surgery to another, surgical technique used, operative findings at baseline appendectomy according to the American Association for the Surgery of Trauma (AAST) classification, and hospital stay were collected. RESULTS: 3,698 appendicitis cases underwent surgery, 76.7% of which laparoscopically, with 37.2% being advanced (grades II-V of the AAST classification). Mean operating time was 50.4 minutes (49.8 ± 20.1 for laparoscopy vs. 49.9 ± 20.1 for open surgery, p > 0.05), and longer in patients requiring re-intervention (68.6 ± 27.2 vs. 49.1 ± 19.3, p < 0.001). 76 re-interventions (2.05%) were carried out. The causes included postoperative infection (n = 46), intestinal obstruction (n = 20), dehiscence (n = 4), and others (n = 6). Re-intervention risk was not impacted by the baseline approach used (open surgery or laparoscopy, OR: 1.044, 95% CI: 0.57-1.9), but it was by appendicitis progression (7.8% advanced vs. 0.7% incipient, OR: 12.52, 95% CI: 6.18-25.3). There was a tendency to use the same approach both at baseline appendectomy and re-intervention. This occurred in 72.2% of laparoscopic appendectomies, and in 67.7% of open appendectomies. The minimally invasive approach (50/76) was more frequent than the open one (27 laparoscopies and 23 ultrasound-guided drainages vs. 26 open surgeries) (p < 0.05). 55% of obstruction patients underwent re-intervention through open surgery (p > 0.05). CONCLUSION: Re-intervention rate was higher in advanced appendicitis cases. In this series, the minimally invasive approach (laparoscopic or ultrasound-guided drainage) was the technique of choice for re-interventions.


INTRODUCCION: La apendicitis aguda es la causa más frecuente de abdomen agudo en niños. El objetivo de este trabajo es estudiar las causas, abordaje y resultados de las complicaciones que requieren intervención quirúrgica después de la apendicectomía. MATERIAL Y METODOS: Estudio retrospectivo de las apendicectomías realizadas en 3 centros de tercer nivel entre 2015-2019. Se recogieron las complicaciones, causas y número de reintervenciones, intervalo entre ambas cirugías, técnica empleada, hallazgos operatorios según la Clasificación de la American Association for the Surgery of Trauma (AAST) en la apendicectomía inicial y tiempo de ingreso. RESULTADOS: Se intervinieron 3.698 apendicitis, un 76,7% por vía laparoscópica, encontrando un 37,2% evolucionadas (grado II-V de la clasificación AAST). El tiempo medio quirúrgico fue de 50,4 minutos (laparoscopia 49,8 ± 20,1 vs. laparotomía 49,9 ± 20,1, p > 0,05), superior en aquellos pacientes que requirieron reintervención (68,6 ± 27,2 vs. 49,1 ± 19,3, p < 0,001). Se realizaron 76 reintervenciones (2,05%). Las causas fueron: infección postoperatoria (n = 46), obstrucción intestinal (n = 20), dehiscencia (n = 4) y otras (n = 6). El abordaje inicial no influyó en el riesgo de reintervención (laparotomía o laparoscopia, OR 1,044, IC 95% 0,57-1,9), pero sí el grado de evolución de la apendicitis (7,8% evolucionadas vs. 0,7% incipientes, OR 12,52, IC 95% 6,18-25,3). Hubo una tendencia a reintervenir por el mismo abordaje que la apendicectomía, esto ocurrió en un 72,2% de las apendicectomías laparoscópicas y en un 67,7% de las apendicectomías abiertas. El abordaje mínimamente invasivo (50/76) fue más frecuente que la laparotomía (27 laparoscopias y 23 drenajes ecoguiados frente a 26 laparotomías) (p < 0,05). El 55% de los pacientes obstruidos se reintervinieron por vía abierta (p > 0,05). CONCLUSION: El índice de reintervención fue superior en las apendicitis evolucionadas. En esta serie, el abordaje mínimamente invasivo (laparoscópico o drenaje ecoguiado) fue la técnica de elección en las reintervenciones.

RESUMO

Objetivos: Caracterizar la situación de la asistencia sociosanitaria y de dependencia en la comunidad autónoma de Cantabria y analizar la aplicación de cuidados por parte del personal de enfermería tanto del centro de salud como de los propios de los centros sociosanitarios y de dependencia. Metodología:Estudio descriptivo transversal y multicéntrico en el cual se diseñó una encuesta ad-hoc anónima enviada a todos los centros sociosanitarios de la comunidad autónoma de Cantabria para su cumplimentación. Resultados: Se obtuvieron 54 de las 60 encuestas enviadas, el total de residentes en centros sociosanitarios de Cantabria es de 5.335 personas con una media del 86,4% de pacientes dependientes y un total de 169 profesionales de enfermería que trabajan en estos centros. La ratio enfermera/paciente es de 32 pacientes por enfermera y la media de estos profesionales es de 4,12. La enfermera del centro de salud acude a los centros sociosanitarios 51,66 min/semana. Conclusiones: La situación actual es deficitaria en enfermeras por centro y en ratio por residente, cifras que no posibilitan la atención de enfermería adecuada. La ausencia de profesionales de enfermería no garantiza la continuidad de cuidados, la prevención ni el seguimiento de patologías crónicas. La presencia de enfermeras propias supone una mayor implicación, mejoras en la calidad de vida, calidad asistencial, mayor satisfacción general, minimización de errores y un descenso del intrusismo profesional (AU)


Objectives: Characterize the situation of the socio-sanitary assistance and dependency situation in the autonomous community (region) of Cantabria and to analyze the application of care by the nurses of the health center and the nurses of the sociosanitary and dependency centers. Methodology: Cross-sectional and multicenter descriptive study in which an anonymous ad-hoc survey was designed and sent to all the socio-sanitary centers of the autonomous community of Cantabria to be filled out. Results: A total of 54 of the 60 surveys sent were returned; the total number of residents in socio-sanitary centers in Cantabria is 5,335 people, with an average of 86.4% of dependent patients and a total of 169 nursing professionals who work in these centers. The nurse/patient ratio is 32 patients per nurse and the average of these professionals is 4.12. The health center nurse goes to the socio-sanitary centers 51.66 min/week. Conclusions: The current situation is deficient in nurses per center and in ratio per resident, figures that do not allow for adequate nursing care. The absence of nursing professionals does not guarantee the continuous care, prevention or monitoring of chronic pathologies. The presence of own nurses implies greater involvement, improvements in quality of life, quality of care, greater general satisfaction, minimization of errors and a decrease in professional intrusion (AU)

RESUMO

Objetivos: El uso del inhibidor mTOR sirolimus ha supuesto unavance en el tratamiento de pacientes con anomalías vasculares complicadas. El objetivo de este estudio es presentar nuestra serie de pacientespediátricos con anomalías vasculares tratados con sirolimus oral y haceruna revisión de la literatura al respecto. Material y métodos: Se realizó un análisis retrospectivo de lospacientes con anomalías vasculares complicadas tratados con sirolimusoral en nuestro centro desde el año 2016. La dosis inicial utilizada fuede 0,8 mg/m2 cada 12 horas y el rango terapéutico de 5-15 ng/ml. Todos los pacientes recibieron profilaxis con trimetoprim-sulfametoxazol. Resultados: Se incluyeron seis niños, tres varones y tres mujeres, con una edad media al inicio del tratamiento de 9,5 años. Trespresentaban una malformación linfática en cabeza y cuello, dos unamalformación venosa en miembro inferior y la última una malformación combinada linfática-venosa a nivel toracoabdominal. Todos habíanrecibido múltiples tratamientos previos sin mejoría. Tras el inicio desirolimus, cinco pacientes mejoraron clínicamente (tiempo medio 3,6meses) y cuatro radiológicamente (tiempo medio 6,6 meses). Se registraron efectos adversos leves y transitorios en tres casos. Actualmente,cinco pacientes continúan con el tratamiento. Conclusiones: El sirolimus oral es un tratamiento eficaz y seguroen pacientes con anomalías vasculares complicadas. Nuestros resultadosapoyan su uso en malformaciones linfáticas y venosas en las que hanfracasado otros tratamientos, presentando buenas respuestas sintomáticasy, en menor medida, radiológicas.(AU)


Objective: Sirolimus mTOR inhibitor represents a major advancein the treatment of patients with complicated vascular abnormalities.The objective of this study was to present our series of pediatric patientswith vascular abnormalities treated with oral sirolimus, and to conducta review of the relevant literature. Materials and methods: A retrospective analysis of patients withcomplicated vascular abnormalities treated with oral sirolimus in ourhealthcare facility from 2016 was carried out. Initial dosage was 0.8 mg/m 2 every 12 hours, and therapeutic range was 5-15 ng/ml. All patientsreceived trimethoprim-sulfamethoxazole prophylaxis. Results: 6 children –3 boys and 3 girls– with a mean age of 9.5years at treatment initiation were included. 3 of them had head and necklymphatic malformation, 2 had lower limb venous malformation, and 1had combined lymphatic-venous malformation at the thoracoabdominal level. They all had received multiple previous treatments withoutimprovement. Following sirolimus initiation, 5 patients had clinicalimprovement (mean time: 3.6 months) and 4 had radiological improvement (mean time: 6.6 months). Mild and transitory adverse effects werenoted in the 3 cases. Today, 5 patients remain under treatment. Conclusions: Oral sirolimus is an effective and safe treatment inpatients with complicated vascular abnormalities. Our results supportsirolimus use in lymphatic and venous malformations in which previoustreatments have failed, with a good symptomatic and, to a lesser extent,radiological response.(AU)

RESUMO

OBJECTIVES: Laparoscopic learning curves are slow, and there are no uniform surgical skill acquisition models. Therefore, our objective was to assess a laparoscopic skill learning program in individuals without any surgical experience, analyzing the learning curve by means of a certified custom-made simulator, and evaluating whether previous surgical experience had an impact on the learning curve. MATERIAL AND METHODS: A certified custom-made simulator and laparoscopic instruments were used to assess 20 university students who performed 10 repetitions of 3 exercises of growing difficulty (eye-hand coordination, hand-hand coordination, and cutting). Three parameters were analyzed: total time with each hand, total mistakes with each hand, and three items of the OSATS technical skill scale. The two first exercises were compared with a group of 14 experienced surgeons. Statistical analysis using repeated-measures Anova and Student's t-test was carried out (p < 0.05). RESULTS: Significant time improvement with each repetition was demonstrated in the three exercises. Curve stabilization was faster in surgeons (2-4 repetitions) than in students (8-9). Time reduction was noted in the first and second exercises in both groups, with 44.08% and 33.1% shorter times, respectively. CONCLUSIONS: Individuals without surgical experience acquired basic laparoscopic skills using a custom-made simulator, which allows simple surgical techniques to be carried out in an inexpensive, accessible fashion. Previous surgical experience was associated with a shorter learning curve. The custom-made simulator allowed individuals with and without surgical experience to be distinguished from each other.

OBJECTIVES: Laparoscopic learning curves are slow, and there are no uniform surgical skill acquisition models. Therefore, our objective was to assess a laparoscopic skill learning program in individuals without any surgical experience, analyzing the learning curve by means of a certified custom-made simulator, and evaluating whether previous surgical experience had an impact on the learning curve. MATERIALS AND METHODS: A certified custom-made simulator and laparoscopic instruments were used to assess 20 university students who performed 10 repetitions of 3 exercises of growing difficulty (eye-hand coordination, hand-hand coordination, and cutting). Three parameters were analyzed: total time with each hand, total mistakes with each hand, and three items of the OSATS technical skill scale. The two first exercises were compared with a group of 14 experienced surgeons. Statistical analysis using repeated-measures Anova and Student's t-test was carried out (p < 0.05). RESULTS: Significant time improvement with each repetition was demonstrated in the three exercises. Curve stabilization was faster in surgeons (2-4 repetitions) than in students (8-9). Time reduction was noted in the first and second exercises in both groups, with 44.08% and 33.1% shorter times, respectively. CONCLUSIONS: Individuals without surgical experience acquired basic laparoscopic skills using a custom-made simulator, which allows simple surgical techniques to be carried out in an inexpensive, accessible fashion. Previous surgical experience was associated with a shorter learning curve. The custom-made simulator allowed individuals with and without surgical experience to be distinguished from each other

RESUMO

OBJECTIVE: Sirolimus mTOR inhibitor represents a major advance in the treatment of patients with complicated vascular abnormalities. The objective of this study was to present our series of pediatric patients with vascular abnormalities treated with oral sirolimus, and to conduct a review of the relevant literature. MATERIAL AND METHODS: A retrospective analysis of patients with complicated vascular abnormalities treated with oral sirolimus in our healthcare facility from 2016 was carried out. Initial dosage was 0.8 mg/m2 every 12 hours, and therapeutic range was 5-15 ng/ml. All patients received trimethoprim-sulfamethoxazole prophylaxis. RESULTS: 6 children -3 boys and 3 girls- with a mean age of 9.5 years at treatment initiation were included. 3 of them had head and neck lymphatic malformation, 2 had lower limb venous malformation, and 1 had combined lymphatic-venous malformation at the thoracoabdominal level. They all had received multiple previous treatments without improvement. Following sirolimus initiation, 5 patients had clinical improvement (mean time: 3.6 months) and 4 had radiological improvement (mean time: 6.6 months). Mild and transitory adverse effects were noted in the 3 cases. Today, 5 patients remain under treatment. CONCLUSIONS: Oral sirolimus is an effective and safe treatment in patients with complicated vascular abnormalities. Our results support sirolimus use in lymphatic and venous malformations in which previous treatments have failed, with a good symptomatic and, to a lesser extent, radiological response.


OBJETIVOS: El uso del inhibidor mTOR sirolimus ha supuesto un avance en el tratamiento de pacientes con anomalías vasculares complicadas. El objetivo de este estudio es presentar nuestra serie de pacientes pediátricos con anomalías vasculares tratados con sirolimus oral y hacer una revisión de la literatura al respecto. MATERIAL Y METODOS: Se realizó un análisis retrospectivo de los pacientes con anomalías vasculares complicadas tratados con sirolimus oral en nuestro centro desde el año 2016. La dosis inicial utilizada fue de 0,8 mg/m2 cada 12 horas y el rango terapéutico de 5-15 ng/ml. Todos los pacientes recibieron profilaxis con trimetoprim-sulfametoxazol. RESULTADOS: Se incluyeron seis niños, tres varones y tres mujeres, con una edad media al inicio del tratamiento de 9,5 años. Tres presentaban una malformación linfática en cabeza y cuello, dos una malformación venosa en miembro inferior y la última una malformación combinada linfática-venosa a nivel toracoabdominal. Todos habían recibido múltiples tratamientos previos sin mejoría. Tras el inicio de sirolimus, cinco pacientes mejoraron clínicamente (tiempo medio 3,6 meses) y cuatro radiológicamente (tiempo medio 6,6 meses). Se registraron efectos adversos leves y transitorios en tres casos. Actualmente, cinco pacientes continúan con el tratamiento. CONCLUSIONES: El sirolimus oral es un tratamiento eficaz y seguro en pacientes con anomalías vasculares complicadas. Nuestros resultados apoyan su uso en malformaciones linfáticas y venosas en las que han fracasado otros tratamientos, presentando buenas respuestas sintomáticas y, en menor medida, radiológicas.

RESUMO

INTRODUCCIÓN: La invaginación intestinal representa la causa más frecuente de obstrucción intestinal entre los 6 meses y los 3 años, siendo secundaria en el 0,3-20% de los casos. El divertículo de Meckel es una causa común de invaginación secundaria y su tratamiento es fundamentalmente quirúrgico. MATERIAL Y MÉTODOS: Se revisaron retrospectivamente los casos codificados como invaginación intestinal en el Servicio de Urgencias Pediátricas del Hospital 12 de Octubre de Madrid entre 2013 y 2018. Se incluyeron 130 pacientes. RESULTADOS: En 10 de los 130 pacientes se identificó una causa subyacente: 5 linfomas intestinales, 4 divertículos de Meckel y 1 quiste de duplicación intestinal. Los casos secundarios fueron más frecuentes en varones (4:1), niños mayores de 3 años (60%) e invaginación ileocólica (90%). La invaginación por divertículo de Meckel afectó a 4 niños, 3 varones y 1 mujer, de entre 1 y 4 años. La ecografía diagnosticó la invaginación en los cuatro casos, pero sólo en uno sugirió divertículo de Meckel. En todos los casos, el tratamiento quirúrgico requerido incluyó reducción manual de la invaginación, seguida de diverticulectomía o resección intestinal más anastomosis. CONCLUSIONES: Las invaginaciones secundarias son más frecuentes en niños mayores de 3 años y en quienes fracasa el tratamiento conservador. El divertículo de Meckel es una de las causas más comunes de invaginación secundaria, sus manifestaciones clínicas son inespecíficas y su diagnóstico preoperatorio sigue suponiendo un reto en la actualidad. La utilidad del abordaje laparoscópico/laparoasistido en el tratamiento de las invaginaciones aún es limitada


INTRODUCTION: Intussusception is the most common cause of intestinal obstruction between 6 months and 3 years, having a pathological lead point in 0,3-20% of cases. Meckel's diverticulum is a frequent cause of secondary intussusception, which treatment is mostly surgical. METHODS: This work is a retrospective review of 130 patients diagnosed as intussusceptions. The samples were taken between 2013 and 2018, at the Department of Pediatric Emergency from the Hospital 12 de Octubre (Madrid). RESULTS: Pathological lead point was identified in ten cases (out of 130 patients): 5 intestinal lymphomas, 4 Meckel's diverticulums and 1 intestinal duplication cyst. Secondary intussusception was more common in males (4:1); children older than 3 years (60%); and patients with ileocolic intussusception (90%). Meckel's diverticulum affected 4 children between 1 to 4 years old, 3 males and 1 female. All were diagnosed for the intestinal invagination by ultrasound, but only in one case it suggested Meckel's diverticulum. Required surgical treatment always included manual reduction of intussusceptions, followed of diverticulectomy or intestinal resection plus anastomosis. CONCLUSIONS: Secondary intussusception is more common in children older than 3 years where conservative treatment fails. Meckel's diverticulum is one of the most common causes of secondary invagination, its clinical manifestations are not specific and, at present, its preoperative diagnosis is challenging. Currently, the use of the laparoscopic/laparoassisted approach is limited for the treatment of invaginations

RESUMO

Schistosomiasis is one of the most prevalent Neglected Tropical Disease, affecting approximately 250 million people worldwide. Schistosoma mansoni is the most important species causing human intestinal schistosomiasis. Despite significant efforts in recent decades, the global disease burden of schistosomiasis remains extremely high. This could partly be attributed to the absence of accurate diagnostic tools, primarily in endemic areas. Loop-mediated isothermal amplification (LAMP) is increasingly used in molecular diagnostics as a field-friendly alternative to many other complex molecular methods and it has been proposed as an ideal candidate for revolutionizing point-of-care molecular diagnostics. In a previous work, a LAMP-based method to detect S. mansoni DNA (SmMIT-LAMP) was developed by our research group for early diagnosis of active schistosomiasis in an experimental infection murine model. The SmMIT-LAMP has been further successfully evaluated in both human stool and snail samples and, recently, in human urine samples. In this study, we developed an important improvement for SmMIT-LAMP molecular assay, transforming it into a cold maintenance dry format suitable for potentially manufacturing as kit for ready-to-use for schistosomiasis diagnosis. This procedure could be applied to create dry LAMP kits for a laboratory setting and for diagnostic applications for other neglected tropical diseases.

RESUMO

Epigallo-catechin-3-gallate (EGCG), found in the leaves of Camellia sinensis (green tea), has antioxidant- and scavenger-functions and acts neuroprotectively. It has been publicized as anti-aging remedy but data on potential cellular mechanisms are scarce. Recent studies claimed that EGCG specifically promotes neural precursor cell proliferation in the dentate gyrus of C57Bl/6 mice, without changes at the level of immature and mature new neurons. We here analyzed the effects of EGCG on adult hippocampal neurogenesis in male Balb/C mice and saw a different pattern. Two weeks of treatment with EGCG (0, 0.625, 1.25, 2.5, 5 and 10mg/kg) showed a dose-response curve that peaked at 2.5mg/kg of EGCG with significantly increased cell survival without affecting cell proliferation but decreasing apoptotic cells. Also, EGCG increased the population of doublecortin-(DCX)-expressing cells that comprises the late intermediate progenitor cells (type-2b and -3) as well as immature neurons. After EGCG treatment, the young DCX-positive neurons showed more elaborated dendritic trees. EGCG also significantly increased net neurogenesis in the adult hippocampus and increased the hippocampal levels of phospho-Akt. Ex vivo, EGCG exerted a direct effect on survival and neuronal differentiation of adult hippocampal precursor cells, which was absent, when PI3K, a protein upstream of Akt, was blocked. Our results thus support a pro-survival and a pro-neurogenic role of EGCG. In the context of the conflicting published results, however, potential genetic modifiers must be assumed. These might help to explain the overall variability of study results with EGCG. Our data do indicate, however, that natural compounds such as EGCG can in principle modulate brain plasticity.
