Encuesta de satisfacción de padres de pacientes y equipo médico sobre el consentimiento informado en un hospital pediátrico de la Ciudad de Buenos Aires / Satisfaction survey of parents and medical staff regarding informed consent in a pediatric hospital in the city of Buenos Aires

El consentimiento informado es un proceso en el que un paciente libre y bien informado o sus representantes autorizan o no un procedimiento médico. Objetivos: El objetivo del estudio fue explorar el grado de satisfacción de padres de pacientes y profesionales con respecto al CI implementado en diferentes áreas del hospital. Métodos: Estudio observacional y descriptivo mediante encuesta anónima, a médicos y padres de pacientes atendidos en el hospital entre enero y julio de 2018. Resultados: Se obtuvieron 158 respuestas de profesionales y 139 de padres. Para el 50% de los padres el CI es un proceso para mejorar la calidad. El 81% de ellos consideró que recibió la información, la comprendieron y pudieron aclarar dudas. El 89% recibió la información del médico y el 59% en el lugar adecuado. De los profesionales, 57% consideró al CI como un proceso de información para mejorar la calidad. El 3% estimó que los padres comprenden la información siempre, el 66% consideró que el CI contiene la información suficiente y 13% le entregó una copia a la familia. Conclusiones: El grado de satisfacción de los padres en relación al CI es alto mientras que el de los profesionales es moderado. Hay que continuar trabajando en el proceso de comunicación entre ambos grupos (AU)

Informed consent is a process based on which a free and wellinformed patient or his/her representatives decide whether or not to authorize a medical procedure. Objectives: The aim of the study was to explore the degree of satisfaction of parents of patients and professionals regarding the IC implemented in different areas of the hospital. Methods: Observational and descriptive study using an anonymous survey of physicians and parents of patients treated at the hospital between January and July 2018. Results: the survey was responded by 158 physicians and 139 parents. Overall, 50% of the parents considered that the IC is part of a quality improvement process; 81% of them found they received adequate information, understood it, and were able to clarify doubts. Eighty-nine percent received the information from the physician and 59% in the appropriate area. Of the professionals, 57% considered the IC to be an information process to improve quality; 3% felt that parents always understand the information; 66% felt that the IC contains sufficient information; and 13% gave the family a copy. Conclusions: A degree of satisfaction with the IC was found in parents while it was moderate among physicians. It is necessary to continue working on the communication process between both groups (AU)

Eventos adversos supuestamente atribuibles a la vacunación e inmunización asociados a la vacuna anti-COVID-19 Sputnik V en el personbal del hospital Juan P. Garrahan / Adverse events allegedly attributable to vaccination and immunization with the anti-COVID-19 Sputnik V vaccine in the staff of the Hospital Juan P. Garrahan

Introducción: Debido a la emergencia provocada por la pandemia por el virus SARS-CoV-2 se ha producido una crisis sanitaria global. Una vez disponibles las vacunas, se espera que jueguen un rol decisivo para el control de la enfermedad. Dichas vacunas fueron desarrolladas en tiempo récord por lo que es esencial monitorear su seguridad. Durante la Campaña de Vacunación contra COVID-19, todos los Eventos supuestamente atribuibles a vacunación e inmunización (ESAVI) debieron ser notificados al Ministerio de Salud de la Nación a través del Sistema Integrado de Información Sanitaria de Argentina (SIISA). Materiales y métodos: Se realizó un estudio observacional prospectivo desde el 04/01/2021 al 05/05/2021 en el personal del Hospital Garrahan. Se utilizaron dos métodos de vigilancia de ESAVI. La vigilancia pasiva incluyó las notificaciones voluntarias recibidas de forma telefónica y a través de un cuestionario publicado en intranet. La vigilancia activa se realizó sobre los primeros 947 trabajadores inmunizados, enviando el mismo cuestionario por WhatsApp. Resultados: Hasta el día 05/05/2021 fueron inmunizados 5056 agentes, 4865 con las dos dosis. Se notificaron 473 ESAVI. De ellos, 304 correspondían a la primera dosis y 169 a la segunda. La cantidad de notificaciones según su origen fue de 136 para la vigilancia pasiva, y 333 para la vigilancia activa. Se registraron 5 ESAVI graves; tres anafilaxias, un escotoma secundario a la hipertermia generada por la vacuna y una reacción alérgica grave. Los síntomas locales más frecuentes fueron: dolor, enrojecimiento, hinchazón e induración. Los síntomas sistémicos más frecuentes fueron: fiebre, febrícula, astenia, cefalea, mialgia, artralgia y síntomas gastrointestinales. Como tratamiento en la mayoría de los casos se utilizó paracetamol. Discusión: El presente trabajo logró recolectar un número significativo de notificaciones, brindando información útil al tratarse de una vacuna recientemente aprobada en nuestro país y el mundo. (AU)

Introduction: Due to the SARS-CoV-2 pandemic emergency, a global health crisis has occurred. Once vaccines become available, they are expected to play a decisive role in controlling the disease. These vaccines were developed in record time, and therefore it is essential to monitor their safety. During the COVID-19 Vaccination Campaign, all Events Suspected to be Attributable to Vaccination and Immunization (ESAVI) had to be notified to the National Ministry of Health through the Integrated Health Information System of Argentina (SIISA). Material and methods: A prospective observational study was conducted from 04/01/2021 to 05/05/2021 in the staff of Garrahan Hospital. Two methods of ESAVI surveillance were used. Passive surveillance included voluntary notifications received by telephone and through a questionnaire posted on intranet. Active surveillance was conducted on the first 947 immunized workers, sending the same questionnaire by WhatsApp. Results: Up to 05/05/2021, 5056 workers were immunized, of whom 4865 with two doses. A total of 473 ESAVI were reported. Of these, 304 corresponded to the first dose and 169 to the second. The number of notifications was 136 for passive surveillance and 333 for active surveillance. Five severe ESAVIs were recorded; three anaphylaxis, one scotoma secondary to vaccine-generated hyperthermia, and one severe allergic reaction. The most frequent local symptoms were: pain, redness, swelling, and induration. The most frequent systemic symptoms were: mild fever or fever, asthenia, headache, myalgia, arthralgia, and gastrointestinal symptoms. Paracetamol was used as treatment in most cases. Discussion: In the present study a significant number of notifications was collected, providing useful information on a vaccine recently approved in our country and in the world (AU)

Elective, Non-urgent Procedures and Aesthetic Surgery in the Wake of SARS-COVID-19: Considerations Regarding Safety, Feasibility and Impact on Clinical Management.

BACKGROUND: The worldwide spread of a novel coronavirus disease (COVID-19) has led to a near total stop of non-urgent, elective surgeries across all specialties in most affected countries. In the field of aesthetic surgery, the self-imposed moratorium for all aesthetic surgery procedures recommended by most international scientific societies has been adopted by many surgeons worldwide and resulted in a huge socioeconomic impact for most private practices and clinics. An important question still unanswered in most countries is when and how should elective/aesthetic procedures be scheduled again and what kind of organizational changes are necessary to protect patients and healthcare workers when clinics and practices reopen. Defining manageable, evidence-based protocols for testing, surgical/procedural risk mitigation and clinical flow management/contamination management will be paramount for the safety of non-urgent surgical procedures. METHODS: We conducted a MEDLINE/PubMed research for all available publications on COVID-19 and surgery and COVID-19 and anesthesia. Articles and referenced literature describing possible procedural impact factors leading to exacerbation of the clinical evolution of COVID-19-positive patients were identified to perform risk stratification for elective surgery. Based on these impact factors, considerations for patient selection, choice of procedural complexity, duration of procedure, type of anesthesia, etc., are discussed in this article and translated into algorithms for surgical/anesthesia risk management and clinical management. Current recommendations and published protocols on contamination control, avoidance of cross-contamination and procedural patient flow are reviewed. A COVID-19 testing guideline protocol for patients planning to undergo elective aesthetic surgery is presented and recommendations are made regarding adaptation of current patient information/informed consent forms and patient health questionnaires. CONCLUSION: The COVID-19 crisis has led to unprecedented challenges in the acute management of the crisis, and the wave only recently seems to flatten out in some countries. The adaptation of surgical and procedural steps for a risk-minimizing management of potential COVID-19-positive patients seeking to undergo elective aesthetic procedures in the wake of that wave will present the next big challenge for the aesthetic surgery community. We propose a clinical algorithm to enhance patient safety in elective surgery in the context of COVID-19 and to minimize cross-contamination between healthcare workers and patients. New evidence-based guidelines regarding surgical risk stratification, testing, and clinical flow management/contamination management are proposed. We believe that only the continuous development and broad implementation of guidelines like the ones proposed in this paper will allow an early reintegration of all aesthetic procedures into the scope of surgical care currently performed and to prepare the elective surgical specialties better for a possible second wave of the pandemic.

The Impact of Culturing the Organ Preservation Fluid on Solid Organ Transplantation: A Prospective Multicenter Cohort Study.

BACKGROUND: We analyzed the prevalence, etiology, and risk factors of culture-positive preservation fluid and their impact on the management of solid organ transplant recipients. METHODS: From July 2015 to March 2017, 622 episodes of adult solid organ transplants at 7 university hospitals in Spain were prospectively included in the study. RESULTS: The prevalence of culture-positive preservation fluid was 62.5% (389/622). Nevertheless, in only 25.2% (98/389) of the cases were the isolates considered "high risk" for pathogenicity. After applying a multivariate regression analysis, advanced donor age was the main associated factor for having culture-positive preservation fluid for high-risk microorganisms. Preemptive antibiotic therapy was given to 19.8% (77/389) of the cases. The incidence rate of preservation fluid-related infection was 1.3% (5 recipients); none of these patients had received preemptive therapy. Solid organ transplant (SOT) recipients with high-risk culture-positive preservation fluid receiving preemptive antibiotic therapy presented both a lower cumulative incidence of infection and a lower rate of acute rejection and graft loss compared with those who did not have high-risk culture-positive preservation fluid. After adjusting for age, sex, type of transplant, and prior graft rejection, preemptive antibiotic therapy remained a significant protective factor for 90-day infection. CONCLUSIONS: The routine culture of preservation fluid may be considered a tool that provides information about the contamination of the transplanted organ. Preemptive therapy for SOT recipients with high-risk culture-positive preservation fluid may be useful to avoid preservation fluid-related infections and improve the outcomes of infection, graft loss, and graft rejection in transplant patients.

Aerosolized Lipid Amphotericin B for Complementary Therapy and/or Secondary Prophylaxis in Patients with Invasive Pulmonary Aspergillosis: A Single-Center Experience.

BACKGROUND: Experience with aerosolized lipid amphotericin B (aeLAB) as therapy or secondary prophylaxis in patients with invasive pulmonary aspergillosis (IPA) is anecdotal. METHODS: We performed a single-center retrospective cohort study to evaluate the efficacy of systemic antifungal therapy with and without aeLAB in patients with proven or probable IPA. Complete or partial response at 3 months was the primary end-point. Clinical response and mortality at 12 months, occurrence of adverse drug reactions and respiratory fungal colonization were secondary end-point. RESULTS: Eleven patients (39%) received aeLAB in addition to systemic antifungal therapy (group A), and 22 (61%) received systemic antifungal therapy only (group B). The use of aeLAB was not standardized. Amphotericin B lipid complex was used in all patients but one, who received liposomal amphotericin B. Five patients received aeLAB as antifungal complementary therapy and 6 received it as secondary prophylaxis. Except for the requirement of inhaled corticosteroids and home oxygen therapy, more frequent in group A, both groups were similar in baseline conditions. A better (nonsignificant) clinical outcome was observed at 3 months in patients receiving aeLAB. Only uncontrolled baseline condition was associated with one-year mortality in univariate analysis (p = 0.002). A multivariate Cox regression analysis suggests that aeLAB, corrected for uncontrolled underlying disease, reduces mortality at 12 months (HR 0.258; 95% CI 0.072-0.922; p = 0.037). CONCLUSION: Although no significant difference was observed in the main variable (3-month clinical response) and in spite of methodological limitations of the study, the possible survival benefit of aeLAB, adjusted for the control of the underlying disease, could justify the performance of well-controlled studies with a greater number of patients.

Use of MRI as a predictive tool for physicochemical and rheologycal features during cured ham manufacturing.

Magnetic resonance imaging (MRI) was used to study the structural changes during dry-cured ham manufacturing. T1, T2 and apparent diffusion coefficient (ADC) were determined. Dry cured hams were analysed at different steps of the manufacturing process (raw, salted, post salted, half-cured and cured). Structural changes were linked with the rheological behaviour, estimated by texture profile analysis (TPA) performed in three different muscles of hams (semimembranosus, semitendinosus and biceps femoris). A decrease for T1, T2 and ADC parameters during the curing process was observed, connected to the dehydration kinetics and salt diffusion. Curing process increased hardness and chewiness and reduced elasticity and cohesiveness. Mathematical models were defined to obtain useful equations to monitor ripening. Multiple and simple linear regression models were performed to predict water and salt content and rheological features evolution through MRI parameters. Best settings were achieved with water and salt content for the three studied muscles (R2 around 0.90). T1, T2 and ADC showed a negative correlation with hardness and a positive relation with springiness and cohesiveness.

Low intensity sonosynthesis of iron carbide@iron oxide core-shell nanoparticles.

Here we demonstrate a simple method for the organic sonosynthesis of stable Iron Carbide@Iron Oxide core-shell nanoparticles (ICIONPs) stabilized by oleic acid surface modification. This robust synthesis route is based on the sonochemistry reaction of organometallic precursor like Fe(CO)5 in octanol using low intensity ultrasonic bath. As obtained, nanoparticles diameter sizes were measured around 6.38 nm ±â€¯1.34 with a hydrodynamic diameter around 25 nm and an estimated polydispersity of 0.27. Core-Shell structure of nanoparticles was confirmed using HR-TEM and XPS characterization tools in which a core made up of iron carbide (Fe3C) and a shell of magnetite (γ-Fe2O3) was found. The overall nanoparticle presented ferromagnetic behavior at 4 K by SQUID. With these characteristics, the ICIONPs can be potentially used in various applications such as theranostic agent due to their properties obtained from the iron oxides and iron carbide phases.

Abstract: OBJECTIVE: To determine the reference values of Homeostasis Model Assessment Insulin Resistance, (HOMA-IR) and Quantitative Insulin Sensitivity Check Index (QUICKI) to define insulin resistance (IR) in women without pregnancy (WP) and each trimester of pregnancy among Mexican women. METHODS: Cross-sectional study, women without pregnancy and pregnant women age >18 years, without pathologies, pre-pregnancy body mass index (BMI) between 18.5-24.9 kg/m2 were included. All participants underwent CTOG 75gr-2h to rule out diabetes. We excluded women with gestational diabetes or any pre-pregnancy pathology, pre-pregnancy BMI <18.5 or ≥25 kg/m2 and multiple pregnancy. Percentiles 5 and 95 were calculated as reference values to define RI by HOMA-IR and QUICKI in women without pregnancy and each trimester of pregnancy. RESULTS: A total of 400 women were included, which were grouped as follows: Group of women without pregnancy (SE): n = 42, quarter Group (T) 1: n = 82, T2 Group: n = 159 and T3 group: n = 117. The reference values of HOMA-IR for the 5th and 95th percentile were: 0.33-2.6, 0.35-1.6, 0.40-2.9 and 0.38-2.6 and QUICKI: (0.33 to 0.46, 0.35 to 0.46, 0.32 to 0.45 and 0.33- 0.45, for groups SE, T1, T2 and T3, respectively. CONCLUSION: The reference value of HOMA-IR to define RI in Mexican women should be ≥2.6 and the T1 ≥1.6, T2 pregnancy: ≥2.9 and T3 ≥2.6 and QUICKI in women <0.33, T1 <0.35, T2 <0.32 and T3 <0.33.

Factores predictivos de recidiva de estenosis uretral tras uretrotomía endoscópica / Predictors of urethral stricture recurrence after endoscopic urethrotomy

Objetivo: El objetivo del trabajo fue analizar las variables clínico-demográficas de la serie y los factores predictores de recidiva de estenosis uretral tras uretrotomía endoscópica. Material y métodos: Se analizó retrospectivamente a 67 pacientes tratados mediante uretrotomía endoscópica tipo Sachse entre junio de 2006 y septiembre de 2014. Se excluyó a los intervenidos previamente de uretrotomía endoscópica o uretroplastia y se incluyó al resto de los pacientes que presentaban estenosis uretral. Se analizó edad, peso, hábito tabáquico, factores de riesgo cardiovascular, número, localización, longitud y etiología de la estenosis, uretrotomía previa, tiempo de sonda vesical y dilataciones posquirúrgicas. Se realizó un análisis univariado y multivariado mediante el test de chi-cuadrado o de Fisher y regresión logística para identificar las variables relacionadas con la recidiva. Resultados: El 37% recidivaron. La mayoría eran > 60 años (56,7%), obesos (74,6%), no fumadores (88%) y sin factores cardiovasculares (56,7%). La mayoría de las estenosis fueron únicas (94%), < 1 cm (82%), de uretra bulbar (64,2%), iatrogénicas (67,2%) y sin uretrotomía previa (89,6%). La mayoría llevaron sonda vesical durante < 15 días (85,1%) y no realizaron dilataciones posquirúrgicas (65,7%). Solamente la longitud de la estenosis resultó factor de riesgo independiente de recidiva (p = 0,025) con un riesgo relativo de 5,7 para un IC 95% (1,21-26,41). Conclusiones: En el tratamiento de la estenosis uretral mediante uretrotomía endoscópica, la longitud de la estenosis > 1 cm es el único factor que predice un incremento del riesgo de recidiva. No se encontró factores clínicos ni demográficos que condicionaran un incremento en la incidencia de recidiva. Del mismo modo, factores técnicos como incrementar el tiempo de sondaje vesical o las dilataciones uretrales no alteran el curso de la enfermedad, por lo que su uso rutinario es innecesario

Objective: The aim of the study was to analyse the clinical-demographic variables of the series and the predictors of urethral stricture recurrence after endoscopic urethrotomy. Material and methods: We retrospectively analysed 67 patients who underwent Sachse endoscopic urethrotomy between June 2006 and September 2014. Those patients who had previously undergone endoscopic urethrotomy or urethroplasty were excluded. The other patients who presented urethral stricture were included. We analysed age, weight, smoking habit, and cardiovascular risk factors, as well as the number, location, length and aetiology of the strictures, previous urethrotomies, vesical catheter duration and postsurgical dilatations. A univariate and multivariate analysis was conducted using the chi-squared test or Fisher's test and logistic regression to identify the variables related to recurrence. Results: Thirty-seven percent of the patients had a relapse. The majority of the patients were older than 60 years (56.7%), obese (74.6%), nonsmokers (88%) and had no cardiovascular factors (56.7%). The majority of the strictures were single (94%), < 1 cm (82%), bulbar urethral (64.2%), iatrogenic (67.2%) and with no prior urethrotomy (89.6%). The majority of the patients carried a vesical catheter for < 15 days (85.1%) and did not undergo postsurgical dilatation (65.7%). Only the length of the stricture was an independent risk factor for recurrence (P = .025; relative risk, 5.7; 95% CI 1.21-26.41). Conclusions: In the treatment of urethral strictures through endoscopic urethrotomy, a stricture length > 1 cm is the only factor that predicts an increase in the risk of recurrence. We found no clinical or demographic factors that caused an increase in the incidence of recurrence. Similarly, technical factors such as increasing the bladder catheterisation time and urethral dilatations did not change the course of the disease. Their routine use is therefore unnecessary

Cavernoplastia con injerto de mucosa oral para el tratamiento quirúrgico de la enfermedad de La Peyronie / Cavernoplasty with oral mucosa graft for the surgical treatment of Peyronie's disease

Introducción: La enfermedad de La Peyronie es un trastorno de la albugínea que condiciona incurvación peneana, y que precisa corrección quirúrgica cuando la deformidad dificulta la penetración. Material y métodos: Análisis retrospectivo de los resultados a corto plazo (longitud del pene, ángulo de incurvación y función eréctil) del tratamiento de la enfermedad de La Peyronie en 10 pacientes mediante cavernoplastia con injerto de mucosa oral. En esencia, el tratamiento incluyó la incisión de la placa fibrótica con bisturí eléctrico y el posterior recubrimiento del defecto cavernoso mediante un parche de mucosa oral. Al sexto mes medimos la longitud e incurvación peneanas, y recogimos la función eréctil mediante el cuestionario IIEF-5. Finalmente, se planteó a los pacientes la pregunta «¿volvería a repetir la misma intervención?». Resultados: La edad media fue de 53,4 años. El seguimiento promedio fue de 22,7 meses y la mediana de 24. La incurvación media preoperatoria fue de 68,5° (50-90°); la longitud media del pene de 11,2 cm (9-15) y el IIEF-5 medio de 16,1 (8-25). La longitud peneana media postoperatoria fue de 10,7 cm y el IIEF-5 medio de 18,9. Las diferencias entre los registros pre- y postoperatorios no alcanzaron significación estadística (p = ns). Un paciente desarrolló disfunción eréctil. En todos los casos la incurvación residual fue < 20°. Nueve pacientes (90%) aseguraron que repetirían la misma intervención. Conclusiones: Los resultados a corto plazo señalan que la cavernoplastia con injerto de mucosa oral puede ser una alternativa a los injertos tradicionales para la corrección quirúrgica de la enfermedad de La Peyronie

Background: Peyronie's disease is a disorder of the tunica albuginea and causes penile curvature, requiring surgical correction when the deformity impedes penetration. Material and methods: Retrospective analysis of the short-term results (penile length, angle of curvature and erectile function) of treating Peyronie's disease in 10 patients through cavernoplasty with oral mucosa graft. Essentially, the treatment included the incision of the fibrotic plaque with electrical scalpel and the subsequent coating of the cavernous defect using a patch of oral mucosa. At month 6, we measured the penile length and curvature and recorded the erectile function using the International Index of Erectile Function-5 (IIEF-5) questionnaire. Finally, the patients were asked 'Would you undergo the same operation again?'. Results: The mean age was 53.4 years. The average and median follow-up was 22.7 months and 24 months, respectively. The mean preoperative curvature was 68.5° (50°-90°), the mean penile length was 11.2 cm (9-15) and the mean IIEF-5 score was 16.1 (8-25). The mean postoperative penile length was 10.7 cm, and the mean IIEF-5 score was 18.9. The differences between the preoperative and postoperative values were not statistically significant (P=ns). One patient developed erectile dysfunction. In all cases, the residual curvature was <20°. Nine patients (90%) stated that they would undergo the same operation. Conclusions: The short-term results suggest that cavernoplasty with oral mucosa graft can be an alternative to traditional grafts for surgically correcting Peyronie's disease

Predicción de recidiva bioquímica tras prostatectomía radical. Nueva herramienta para la selección de candidatos a radioterapia adyuvante / Prediction of biochemical recurrence after radical prostatectomy. New tool for selecting candidates for adjuvant radiation therapy

Objetivo: Diseñar un sumatorio de riesgo para la selección de pacientes para radioterapia adyuvante después de prostatectomía. Material y método: Estudio retrospectivo de 629 pacientes con cáncer de próstata localizado y pN0-pNx tratados con prostatectomía y con un PSA a los 2-3 meses < 0,2 ng/ml. Recidiva bioquímica si PSA > 0,4 ng/ml. Análisis multivariante mediante regresión de Cox. Asignación de puntuación (0-2) en función del HR de las variables significativas. El sumatorio de las puntuaciones definió el sumatorio de riesgo. Resultados: El 19,7% pT3, 24,2% Gleason ≥ 8 y el 26,3% de márgenes quirúrgicos positivos. Mediana de seguimiento de 82 meses. Recidiva bioquímica el 26,6%. El Gleason = 7 (4 + 3) (HR = 2,01, p = 0,008), el Gleason ≥ 8 (HR = 3,07, p < 0,001), el estadio pT3b (HR = 1,93, p = 0,008) y el margen quirúrgico positivo (HR = 2,20, p < 0,001) se identificaron como variables pronosticas independientes de recidiva bioquímica. Se asignó 0 puntos a los pacientes sin variables pronósticas de riesgo, un punto a los pacientes con Gleason = 7 (4 + 3), pT3b o márgenes quirúrgicos positivos y 2 puntos si Gleason ≥ 8. Los pacientes con un sumatorio de riesgo ≤ 2 tuvieron una supervivencia libre de recidiva bioquímica a los 5 y 8 años superior al 50%, en cambio, los pacientes con un sumatorio de riesgo ≥ 3 tuvieron una supervivencia libre de recidiva bioquímica inferior al 44%. Conclusión: Los pacientes con un sumatorio de riesgo ≤ 2 no se beneficiarían de radioterapia adyuvante, mientras que los pacientes con un sumatorio de riesgo ≥ 3 pudieran beneficiarse de radioterapia adyuvante

Objective: To design a risk summation to select patients for adjuvant radiation therapy after prostatectomy. Materials and method: A retrospective study was conducted on 629 patients with localised prostate cancer (pN0–pNx) who were treated with prostatectomy and with a prostate-specific antigen (PSA) value < 0.2 ng/mL at 2–3 months. Biochemical recurrence was defined as a PSA > 0.4 ng/mL. A multivariate Cox regression analysis was performed. A score (0–2) was assigned according to the hazard ratio of the significant variables. The score summation defined the risk summation. Results: A total of 19.7% of the patients were pT3, 24.2% had a Gleason score ≥8, and 26.3% had positive surgical margins. The median follow-up was 82 months. Some 26.6% of the patients experienced biochemical recurrence. The identified prognostic variables independent of biochemical recurrence were a Gleason score = 7 (4 + 3) (HR, 2.01; P = .008), a Gleason score ≥ 8 (HR, 3.07; P < .001), a pT3b stage (HR, 1.93; p = .008) and a positive surgical margin (HR, 2.20; P < .001). We assigned 0 points to patients without risk prognosis variables; 1 point to patients with Gleason scores = 7 (4 + 3), pT3b or positive surgical margins; and 2 points to patients with Gleason scores ≥ 8. The patients with a risk summation ≤ 2 had > 50% survival free of biochemical recurrence at 5 and 8 years. In contrast, the patients with a risk summation ≥ 3 had <44% survival free of biochemical recurrence. Conclusion: The patients with a risk summation ≤ 2 did not benefit from adjuvant radiation therapy, while the patients with a risk summation ≥ 3 might benefit from adjuvant radiation therapy

BACKGROUND: Peyronie's disease is a disorder of the tunica albuginea and causes penile curvature, requiring surgical correction when the deformity impedes penetration. MATERIAL AND METHODS: Retrospective analysis of the short-term results (penile length, angle of curvature and erectile function) of treating Peyronie's disease in 10 patients through cavernoplasty with oral mucosa graft. Essentially, the treatment included the incision of the fibrotic plaque with electrical scalpel and the subsequent coating of the cavernous defect using a patch of oral mucosa. At month 6, we measured the penile length and curvature and recorded the erectile function using the International Index of Erectile Function-5 (IIEF-5) questionnaire. Finally, the patients were asked "Would you undergo the same operation again?". RESULTS: The mean age was 53.4 years. The average and median follow-up was 22.7 months and 24 months, respectively. The mean preoperative curvature was 68.5° (50°-90°), the mean penile length was 11.2cm (9-15) and the mean IIEF-5 score was 16.1 (8-25). The mean postoperative penile length was 10.7cm, and the mean IIEF-5 score was 18.9. The differences between the preoperative and postoperative values were not statistically significant (P=ns). One patient developed erectile dysfunction. In all cases, the residual curvature was <20°. Nine patients (90%) stated that they would undergo the same operation. CONCLUSIONS: The short-term results suggest that cavernoplasty with oral mucosa graft can be an alternative to traditional grafts for surgically correcting Peyronie's disease.

Francisella species in ticks and animals, Iberian Peninsula.

The presence of Francisella species in 2134 ticks, 93 lagomorphs and 280 small mammals from the Iberian Peninsula was studied. Overall, 19 ticks and 6 lagomorphs were positive for Francisella tularensis subsp. holarctica, suggesting, as described for other regions, that lagomorphs may have an important role in the maintenance of F. tularensis in nature. Of the 6 positive lagomorphs, 4 were identified as the European rabbit, Oryctogalus cuniculus. Additionally, 353 ticks and 3 small mammals were PCR positive for Francisella-like endosymbionts (FLEs) and one small mammal was also positive for Francisella hispaniensis-like DNA sequences. Among FLE positive specimens, a variety of sequence types were detected: ticks were associated with 5 lpnA sequence types, with only one type identified per tick, in contrast to 2 lpnA sequence types detected in a single wood mouse (Apodemus sylvaticus). To our knowledge, this is the first report of FLEs in free-living small mammals as well as the first detection of F. hispaniensis-like sequences in a natural setting.

Prediction of biochemical recurrence after radical prostatectomy. New tool for selecting candidates for adjuvant radiation therapy.

OBJECTIVE: To design a risk summation to select patients for adjuvant radiation therapy after prostatectomy. MATERIALS AND METHOD: A retrospective study was conducted on 629 patients with localised prostate cancer (pN0-pNx) who were treated with prostatectomy and with a prostate-specific antigen (PSA) value <0.2ng/mL at 2-3 months. Biochemical recurrence was defined as a PSA >0.4ng/mL. A multivariate Cox regression analysis was performed. A score (0-2) was assigned according to the hazard ratio of the significant variables. The score summation defined the risk summation. RESULTS: A total of 19.7% of the patients were pT3, 24.2% had a Gleason score ≥ 8, and 26.3% had positive surgical margins. The median follow-up was 82 months. Some 26.6% of the patients experienced biochemical recurrence. The identified prognostic variables independent of biochemical recurrence were a Gleason score =7 (4+3) (HR, 2.01; P=.008), a Gleason score ≥ 8 (HR, 3.07; P <.001), a pT3b stage (HR, 1.93; p=.008) and a positive surgical margin (HR, 2.20; P<.001). We assigned 0 points to patients without risk prognosis variables; 1 point to patients with Gleason scores =7 (4+3), pT3b or positive surgical margins; and 2 points to patients with Gleason scores ≥ 8. The patients with a risk summation ≤ 2 had >50% survival free of biochemical recurrence at 5 and 8 years. In contrast, the patients with a risk summation ≥ 3 had <44% survival free of biochemical recurrence. CONCLUSION: The patients with a risk summation ≤ 2 did not benefit from adjuvant radiation therapy, while the patients with a risk summation ≥ 3 might benefit from adjuvant radiation therapy.

[Onychomycosis by yeast not common in diabetics of a health center]. / Onicomicosis por levaduras no comunes en diabéticos de un centro de salud.

BACKGROUND: Mexican diabetic population frequently presents mycosis under foot hyperkeratosis; however, in another type of onychomycosis as the ones that is assumed Candida albicans is the causal agent, it is unknown the frequency, the prevalence and if another Candida species or other yeasts are found. OBJECTIVE: Evaluate the frequency of yeasts causing onychomycosis in diabetic patients looked after in public institutions of health of the State of Hidalgo, Mexico, and its association with clinical epidemiological variables. MATERIALS AND METHODS: An observational, descriptive and transversal study was made on 261 patients, from which one nail sample of each one was obtained, used to isolate and identify dermatophytes and yeasts; the results were statistically correlated with 24 epidemiological parameters. The clinical study was done through interrogation and by medical exploration in order to evaluate Tinea pedis and onychomycosis. RESULTS: Onychomycosis were caused by Candida guilliermondii, Candida parapsilosis, Candida glabrata, Candida krusei, Candida spp., Kodamaea ohmeri, Prototheca wickerhamii and unidentified yeasts. The prevalence for general onychomycosis, by dermatophytes, mixed onychomycosis and by yeasts were: 24.1, 19.5, 2.3 and 14.6%, respectively. Patients with significant probability to be diagnosed as having onychomycosis by yeasts are those wearing open shoes (2.59%); technicians and professionals (10.49%) and alcohol drinkers (3.72%). CONCLUSION: The fact that Candida albicans is not present in this study as causal agent of onychomycosis, and emerging and non-common yeasts were indeed isolated, creates new challenges. It is remarked the clinical criterion that when onychomycosis is suspected in diabetics, the diagnosis for culturing dermatophytes and yeasts should be included.

Exoftalmos unilateral de corta evolución. Una forma de debut de un neuroblastoma / Unilateral exophthalmos with short evolution. One way to debut a neuroblastoma

El neuroblastoma (NB) es el tumor extracraneal sólido más frecuente en la infancia. Representa el 7% de los cánceres pediátricos. Se origina de la cresta neural, y puede aparecer en cualquiera de los sitios anatómicos a lo largo de la cadena ganglionar simpática, así como en la glándula suprarrenal. El 90% ocurre en menores de 5 años. Presenta un amplio espectro de comportamiento clínico. Los estudios muestran metástasis orbitarias en el 10-20% de los casos. La proptosis y equimosis periorbitaria son consideradas dos de los signos clásicos del neuroblastoma en niños. Presentamos el caso de una paciente de 4 años de edad con un neuroblastoma metastásico que se manifestó como una proptosis de corta evolución al diagnóstico, sin otro tipo de sintomatología ni hallazgos en la exploración física. Tras las pruebas complementarias, se la diagnosticó de neuroblastoma estadio IV de la INSS (The International Neuroblastoma Staying System). No se localizó el tumor primario. Se realizó tratamiento con quimioterapia de inducción, terapia de acondicionamiento y trasplante autólogo de progenitores hematopoyéticos, entrando en remisión completa. Posteriormente inmunoterapia, manteniendo enfermedad residual negativa. Queremos destacar la importancia de un diagnóstico precoz en esta patología de cara a la supervivencia del paciente, y que siempre debe considerarse el diagnóstico de NB ante un exoftalmos en un paciente previamente sano. El tratamiento de los pacientes con neuroblastoma de alto riesgo es multimodal, habiendo mejorado el pronóstico el uso combinado de inmunoterapia, ácido 13 cis-retinoico y trasplante autólogo de médula ósea

Neuroblastoma (NB) is an extracranial solid brain tumor found most frequently during childhood. It represents 7% of the pediatric cancers. It originates in the neural crest and can appear in any part of the anatomy along the ganglionic sympathetic chain, as well as in the adrenal gland. 90% of cases occur en children under the age of 5. It presents a broad spectrum of behavior. Studies have shown orbital metastases in 10-20% of cases. Proptosis and ecchymosis periorbitary are considered two classic signs of neuroblastoma in children. We are presenting a case of a 4 year old female patient with metastatic neuroblastoma that manifested like a proptosis of short evolution to its diagnosis, without any other type of symtomatololgy or findings in the physical exploration. After complementary tests she was diagnosed with stage IV neuroblastoma in the INSS (The International Neuroblastoma Staying System). The primary tumor was not located. Complete remission was obtained using induction chemotherapy, conditioning therapy and autologous hematopoietic progenitors transplant. After immunotherapy negative residual disease was maintained. We would like to highlight the importance of early diagnosis in this pathology facing the patient’s survival and must always consider the NB diagnosis when an exophthalmos presents in a previously healthy patient. Treatment in patients with high risk neuroblastoma is multimodal, having improved the prognosis by using a combination of immunotherapy, 13-cis-retinoic acid and the autologous bone marrow transplant

Patterns of tick infestation and their Borrelia burgdorferi s.l. infection in wild birds in Portugal.

Wild birds may act as reservoirs for zoonotic pathogens and may be mechanical carriers of pathogen infected vector ticks through long distances during migration. The aim of this study was to assess tick infestation patterns in birds in Portugal and the prevalence of tick infection by Borrelia burgdorferi s.l. using PCR techniques. Seven tick species were collected from birds including Haemaphysalis punctata, Hyalomma spp., Ixodes acuminatus, Ixodes arboricola, Ixodes frontalis, Ixodes ricinus and Ixodes ventalloi. We found that I. frontalis and Hyalomma spp. were the most common ticks infesting birds of several species and that they were widespread in Portugal. Turdus merula was the bird species that presented the highest diversity of infesting ticks and had one of the highest infestation intensities. B. burgdorferi s.l. was detected in 7.3% (37/505) of Ixodidae ticks derived from birds. The most common genospecies was Borrelia turdi (6.9%), detected in ticks collected from Parus major, T. merula and Turdus philomelos, but Borrelia valaisiana (0.2%) and one Borrelia sp. (0.2%) similar to Borrelia bissettii (96% of similarity of the flaB gene in Blastn) were also detected. This study contributed to a better knowledge of the Ixodidae tick fauna parasitizing birds in Western Europe and to the assessment of the prevalence of B. burgdorferi s.l. associated with birds and their ticks.

Utilization of secondary-treated wastewater for the production of freshwater microalgae.

In this work, we studied the potential use of secondary-treated wastewater as nutrient source in the production of freshwater microalgae strains. Experiments were performed indoors in a semicontinuous mode, at 0.3 day(-1), simulating outdoor conditions. We demonstrated that all the tested strains can be produced by using only secondary-treated wastewater as the nutrient source. The utilization of secondary-treated wastewater imposes nutrient-limiting conditions, with maximal biomass productivity dropping to 0.5 g l(-1) day(-1) and modifies the biochemical composition of the biomass by increasing the amount of lipids and carbohydrates while reducing the biomass protein content. We measured fatty acid content and productivity of up to 25 %d.wt. and 110 mg l(-1) day(-1), respectively. We demonstrated that all the tested strains were capable of completely removing the nitrogen and phosphorus contained in the secondary-treated wastewater, and while the use of this effluent reduced the cells' photosynthetic efficiency, the nitrogen and phosphorus coefficient yield increased. Muriellopsis sp. and S. subpicatus were selected as the most promising strains for outdoor production using secondary-treated wastewater as the culture medium; this was not only because of their high productivity but also their photosynthetic efficiency, of up to 2.5 %, along with nutrient coefficient yields of up to 96 gbiomass gN (-1) and 166 gbiomass gP (-1). Coupling microalgae production processes to tertiary treatment in wastewater treatment plants make it possible to recover nutrients contained in the water and to produce valuable biomass, especially where nutrient removal is required prior to wastewater discharge.
