RESUMO
OBJECTIVE: Cytomegalovirus infection (CMV) is the most common congenital infection in developed countries. The aim of our study was to describe the features of the children that have congenital CMV infection at our hospital for the last 6 years. METHODS: A retrospective descriptive study was designed that included all the children with CMV congenital infection that were diagnosed at tertiary hospital of Madrid Community between 2017 and 2023. RESULTS: Twenty-two children were included. 54.5% have a prenatal diagnosis, 50% of them were in the third trimester, 25% at first trimester and 25% at the second. 22.7% were preterm. CMV was isolated in all the samples with CV more than 1000 copies/ml. When CMV was made in blood, 11/22 (50%) had a high CV. Only one newborn had a high CV at CRL. 44% have affectation at transfontanellar ultrasound evidenced by vasculopathy (62%), intraventricular hemorrhage (IVH) or periventricular calcifications (20%). 68% were asymptomatic, al though 20% had a retarded intrauterine growth (RIG) at birth or clinical features or analytical were objectified (neutropenia, thrombocytopenia, cholestasis). 33% got treatment with val ganciclovir and 33% had sequelae (hearing loss). CONCLUSIONS: CMV congenital infection is still a severe public health issue in developed countries. Most of the cases are mild or asymptomatic even though we should have high clinical suspicion with compatible symptoms and consistent maternal history in order to make an early diagnosis and treatment to prevent or reduce sequelae.

OBJECTIVES: This clinical, analytical, retro-prospective, auto-controlled, not randomized, and not blinded study, aimed to investigate the association of changes in the serum glucose levels with the pre-and-post changes in the size tumor in mm3 in the Non-Functional pituitary adenomas. METHODS: Pre-and post-surgical MRI, as well as the measurements in the serum glucose levels and immunohistochemical techniques were performed in all the patients in the study, with a mean followed-up until 208.57 days. A comparison was made between the reductions in tumor size of hormonally active pituitary adenomas (HSPAs) vs NFPAs. RESULTS: Seventy-four patients were included in this study, of whom, 46 were NFPAs. The decrease in the NFPAs tumor size after surgery was statistically significant (P ≤ 0.0001). The Mean of the differences of both type of tumors in mm3 were -9552 ± 10287. Pre-surgery, the mean of the HSPAs were 8.923 ± 2.078; and the NFPAs were 14.161 ± 1.912. The differences in the tumor size were statistically significant (p = 0.039). Post-surgical, the mean of the HSPAs were 2.079 ± 971, with a (p = 0.14): and the NFPAs were 4.609 ± 1.205. After surgery of the NFPAs, most of the patients-maintained serum levels ≤ 100 mg/dL, with a statistical significance (P ≤ 0.0003). CONCLUSION: This study demonstrates for the first time the correlation between the presence of pre-and post- surgical changes in the NFPAs, with modifications in the levels of serum glucose, and the comparison, pre- and post-surgical between the tumor size of HSPAs and NFPAs.
RESUMO
Maize tortilla is the best-recognized food product of Mexican gastronomy. Artisanal maize tortillas (AMT) are prepared with native maize varieties and a traditional process. The aims of this study were to identify sensory attributes, texture, and color in AMT that allow them to be differentiated from commercial tortillas, and to determine the chemical and mineral composition of both types of tortillas. Six landraces related to four Mexican maize races were used. Two commercial tortillas were included as references (tortillería and supermarket). Tortillas were subjected to sensory analysis by the modified Flash technique, texture and color were measured objectively and chemical and mineral analysis of all tortillas were evaluated. Lime taste and lime smell attributes were relevant to differentiate AMT from commercial tortillas; aftertaste and fracturability attributes were highly associated to supermarket tortillas. The fracturability attribute of tortillas is consider undesirable for taco preparation. Five of the six AMT were characterized by the presence of a layer, a characteristic that is associated with traditional tortilla made by Mexican consumer. Regarding chemical composition, supermarket tortillas exhibited the highest dietary fiber content (17.09%), but showed 30% more Na than AMT, with the exception of tortillas from Purepecha native variety. Besides, supermarket tortilla had 48.9% less Ca than AMT. The sensory attributes relevant to differentiate native maize tortillas from the commercial maize tortilla references were appearance, smell, and taste, while textural and color attributes played a lesser role.
RESUMO
INTRODUCTION: Chronic inguinal pain or inguinodynia following hernioplasty is a relatively common complication that can be very incapacitating. Surgical treatment by triple neurectomy is a therapeutic option when previous treatments (oral/local therapy or neuromodulation) have failed. OBJECTIVE: Retrospective description of the surgical technique and results of laparoscopic and robot-assisted triple neurectomy for chronic inguinodynia. MATERIAL AND METHODS: We describe the inclusion/exclusion criteria as well as the surgical technique applied in 7 patients operated on at the University Health Care Complex of León (Urology Department) after failure of other treatment options. RESULTS: The patients presented chronic groin pain, reporting a preoperative pain VAS of 7.43 out of 10. After surgery, this score was reduced to 3.71 on the first postoperative day and to 4.2 points one year after surgery. Hospital discharge occurred 24 h after surgery with no relevant complications being reported. CONCLUSIONS: Laparoscopic or robot-assisted triple neurectomy is a safe, reproducible, and effective technique for the treatment of chronic groin pain refractory to other treatments.

BACKGROUND: Pituitary adenomas are benign tumors located in the anterior hypophysis. Its appearance is associated with the development of parameters related to metabolic syndrome; therefore, surgical treatment could reduce associated morbimortality. METHODS: Pre- and post-surgical MRI, using the Hardy-Wilson and Knosp classification, and clinical data according to the American Association of Clinical Endocrinology (AACE) criteria for metabolic syndrome: all the patients were followed-up until 208.57 days were reviewed on 217 consecutive patients with pituitary surgery. RESULTS: Seventy-four patients were included in this study. There was a significant reduction in tumor size in mm3 [average pre- and post-surgery respectively: 12,362 mm3 (±12,397); 3,910 mm3 (±7,160)], (p < 0.0001). This was confirmed by the Hardy-Wilson and Knosp classification, where most patients went from grade IV C (33.7%) to grade 0 (12.1%), IA (20.2%), IIB (21.36%), and IIC (16.2%); as well as from grade 4 (24.3%) to grade 0 (45.9%), respectively. After surgery, there were statistically significant reductions in total serum levels of glucose [average pre- and post-surgery, respectively: 116 mg/dL (±26.9); 90 mg/dL (±10.2)], (p < 0.001), triglycerides [average pre- and post-surgery, 240 mg/dL (±102); 171 mg/dL (±60.5)], (p = 0.001); and HDL-c [average pre- and post-surgery, respectively: 39 mg/dL (±11.8); 44.6 mg/dL (±8.4)], (p = 0.029). The other parameters remained unchanged. CONCLUSION: This is the first study to demonstrate the relationship between the presence of pituitary adenoma and significative changes in serum glucose, triglycerides and c-HDL related to metabolic syndrome.
RESUMO
BACKGROUND AND PURPOSE: Automated volumetric analysis of structural MR imaging allows quantitative assessment of brain atrophy in neurodegenerative disorders. We compared the brain segmentation performance of the AI-Rad Companion brain MR imaging software against an in-house FreeSurfer 7.1.1/Individual Longitudinal Participant pipeline. MATERIALS AND METHODS: T1-weighted images of 45 participants with de novo memory symptoms were selected from the OASIS-4 database and analyzed through the AI-Rad Companion brain MR imaging tool and the FreeSurfer 7.1.1/Individual Longitudinal Participant pipeline. Correlation, agreement, and consistency between the 2 tools were compared among the absolute, normalized, and standardized volumes. Final reports generated by each tool were used to compare the rates of detection of abnormality and the compatibility of radiologic impressions made using each tool, compared with the clinical diagnoses. RESULTS: We observed strong correlation, moderate consistency, and poor agreement between absolute volumes of the main cortical lobes and subcortical structures measured by the AI-Rad Companion brain MR imaging tool compared with FreeSurfer. The strength of the correlations increased after normalizing the measurements to the total intracranial volume. Standardized measurements differed significantly between the 2 tools, likely owing to differences in the normative data sets used to calibrate each tool. When considering the FreeSurfer 7.1.1/Individual Longitudinal Participant pipeline as a reference standard, the AI-Rad Companion brain MR imaging tool had a specificity of 90.6%-100% and a sensitivity of 64.3%-100% in detecting volumetric abnormalities. There was no difference between the rate of compatibility of radiologic and clinical impressions when using the 2 tools. CONCLUSIONS: The AI-Rad Companion brain MR imaging tool reliably detects atrophy in cortical and subcortical regions implicated in the differential diagnosis of dementia.

AIMS: (1) to design a training programme for newly hired nursing personnel and (2) to determine self-perception and perceived stress before and after the theoretical and practical parts of the programme with high fidelity simulation activities. METHODS: A pilot quasi-experimental pretest-posttest study without control group conducted in a Paediatric Intensive Care Unit from October 2018 to April 2019 was conducted. A newly hired nursing personnel training programme was first designed and delivered. Later, the participants' self-perception was assessed, as well as their perceived stress and grade of satisfaction using two different Likert scales. RESULTS: A total of 20 newly hired nurses participated in the study, 90% (n = 18) were female with a median age of 25.5 ± 4.53 years. Higher scores were obtained in participants' self-perception before and after the theoretical training. Lower significant median scores of the participants' stress perception were found (6.9 ± 1.57 versus 5.6 ± 1.794). In the practical part of the programme, we obtained higher scores in all items, as well as lower median scores in stress perception (6.4 ± 1.73 versus 5.6 ± 1.93). CONCLUSIONS: A theoretical and practical programme for newly hired nursing personnel in a Paediatric Intensive Care Unit improved participants' self-perception and reduced their perceived median scores in stress levels.

In semiarid agricultural regions, aquifers have watered widespread economic development. Falling water tables, however, drive up energy costs and can make the water toxic for human consumption. The study area is located in central Mexico, where arsenic and fluoride are widely present at toxic concentrations in well water. We simulated the holistic outcomes from three pumping scenarios over 100 years (2020-2120); (S1) pumping rates increase at a similar rate to the past 40 years, (S2) remain constant, or (S3) decrease. Under scenario S1, by 2120, the depth to water table increased to 426 m and energy consumption for irrigation increased to 4 × 109 kWh/yr. Arsenic and fluoride concentrations increased from 14 to 46 µg/L and 1.0 to 3.6 mg/L, respectively. The combined estimated IQ point decrements from drinking untreated well water lowered expected incomes in 2120 by 27% compared to what they would be with negligible exposure levels. We calculated the 100-year Net Present Value (NPV) of each scenario assuming the 2020 average crop value to water footprint ratio of 0.12 USD/m3. Without drinking water mitigation, S1 and S3 yielded relative NPVs of -5.96 × 109 and 1.51 × 109 USD, respectively, compared to the base case (S2). The relative NPV of providing blanket reverse osmosis treatment, while keeping pumping constant (S2), was 11.55 × 109 USD and this gain increased when combined with decreased pumping (S3). If a high value, low water footprint crop was substituted (broccoli, 1.51 USD/m3), the net gains from increasing pumping were similar in size to those of implementing blanket drinking water treatment.
RESUMO
Resumen Introducción: La cirugía ha sido tradicionalmente considerada una especialidad masculina. Se desconoce si el aumento en el número de médicas en las últimas décadas ha producido un aumento significativo en el número de cirujanas. Objetivo: Analizar y visibilizar la participación actual e histórica de las mujeres en Medicina y en Cirugía General en Chile. Materiales y Método: Estudio retrospectivo de la cohorte de médicas/os y cirujanas/os egresados de escuelas de medicina chilenas desde el año 1970, complementado con estudio de corte transversal para conocer la información actual de las cirujanas y residentes. Las fuentes de datos fueron los Registros de la Superintendencia de Salud, CONACEM y el Catastro de la Asociación de Cirujanas. Resultados: Ha existido un aumento sostenido de médicas egresadas sobrepasando a sus pares masculinos a partir de 2018. Las cirujanas representan el 15% del total de cirujanas y cirujanos, y este número se ha duplicado por década a partir de los años 70. Actualmente, 33% de los residentes en formación son de género femenino. Las áreas más comunes de desarrollo son cirugía general (35%), y dentro de las subespecialidades: mama, plástica y cabeza y cuello. Conclusión: Las mujeres siguen siendo minoría en cirugía; sin embargo, se ha producido un aumento progresivo y se espera siga la misma tendencia. Es necesario visibilizar la importancia de las cirujanas para que sirvan como modelo a nuevas generaciones de estudiantes y así poder aumentar la representación femenina en la especialidad.
Introduction: Surgery traditionally has been considered a male discipline. It is unknown if the increase in the number of female doctors in the last decades has increased the number of female surgeons. Aim: Is to analyze and make visible the historical and current participation of women in Medicine and Surgery in Chile. Materials and Method: Retrospective cohort study of all medical doctors and surgeons graduated from chilean Universities since 1970 to date, and cross-sectional study to know current information of female surgeons and residents. Source of data were the Registries of Health Superintendence, CONACEM and the Registry of the Female Surgeon Association. Results: There has been a steady increase in the number of graduated female doctors in Chile, surpassing male doctors since 2018. Female surgeons are 15% of all surgeons, and the number has duplicated every decade since 1970s. Currently, 33% of the residents are female. Main area of developing is general surgery (35%), and within subspecialties: Breast, Plastics, and Head and Neck. Conclusions: Women are still underrepresented in Surgery: however, there has been a steady increase and that trend is expected to continue. It is necessary to make visible the importance of female surgeons to be able to increase female representation.

Resumen En el año 2020 las cirujanas chilenas se reunieron en torno a la necesidad de trabajar para solucionar varios problemas que aquejan a la labor quirúrgica de la mujer en nuestro país, desde la formación de pregrado en adelante. Algunos de estos problemas son la poca visibilidad de la mujer en cirugía y la falta de reconocimiento de las cirujanas líderes y referentes del pasado y actuales. El objetivo de esta investigación fue indagar quienes habían sido las primeras cirujanas de Chile. La búsqueda fue difícil, ya que la información en la internet es escasa, por lo que se recurrió a entrevistas a discípulos y a algunas de las primeras cirujanas tanto en su especialidad o región del país. La cronología muestra lo reciente que ha sido la llegada de cirujanas a algunas regiones o la escasa representatividad de cirujanas en algunas subespecialidades. Esto se puede entender por barreras legales y culturales que han tenido que enfrentar las mujeres desde el ingreso a la carrera de medicina hasta el poder desarrollar la especialidad en cirugía a lo largo de la historia de este país.
In 2020, Chilean women surgeons gathered to discuss different problems affecting the development of a career in surgery. Through the history of the medicine and surgery in Chile, there have been several legal and cultural barriers that have kept women out of this specialty. One of this problem is the lack of knowledge of who were the first female surgeons and the lack of awareness of that there are women that can be leaders as well as male surgeons. So, generations of medical students and residents continue thinking that surgery might be a man's job. The purpose of this investigation is to reveal who went and are the first women surgeon in this country, not only in their time but also in their specialty, so we all know that there were and there still are pioneers among us.

BACKGROUND AND PURPOSE: Accurate and reliable detection of white matter hyperintensities and their volume quantification can provide valuable clinical information to assess neurologic disease progression. In this work, a stacked generalization ensemble of orthogonal 3D convolutional neural networks, StackGen-Net, is explored for improving automated detection of white matter hyperintensities in 3D T2-FLAIR images. MATERIALS AND METHODS: Individual convolutional neural networks in StackGen-Net were trained on 2.5D patches from orthogonal reformatting of 3D-FLAIR (n = 21) to yield white matter hyperintensity posteriors. A meta convolutional neural network was trained to learn the functional mapping from orthogonal white matter hyperintensity posteriors to the final white matter hyperintensity prediction. The impact of training data and architecture choices on white matter hyperintensity segmentation performance was systematically evaluated on a test cohort (n = 9). The segmentation performance of StackGen-Net was compared with state-of-the-art convolutional neural network techniques on an independent test cohort from the Alzheimer's Disease Neuroimaging Initiative-3 (n = 20). RESULTS: StackGen-Net outperformed individual convolutional neural networks in the ensemble and their combination using averaging or majority voting. In a comparison with state-of-the-art white matter hyperintensity segmentation techniques, StackGen-Net achieved a significantly higher Dice score (0.76 [SD, 0.08], F1-lesion (0.74 [SD, 0.13]), and area under precision-recall curve (0.84 [SD, 0.09]), and the lowest absolute volume difference (13.3% [SD, 9.1%]). StackGen-Net performance in Dice scores (median = 0.74) did not significantly differ (P = .22) from interobserver (median = 0.73) variability between 2 experienced neuroradiologists. We found no significant difference (P = .15) in white matter hyperintensity lesion volumes from StackGen-Net predictions and ground truth annotations. CONCLUSIONS: A stacked generalization of convolutional neural networks, utilizing multiplanar lesion information using 2.5D spatial context, greatly improved the segmentation performance of StackGen-Net compared with traditional ensemble techniques and some state-of-the-art deep learning models for 3D-FLAIR.

Resumen Introducción: Es importante mantener programas de vigilancia bacteriana para disminuir resistencia y definir esquemas farmacológicos adecuados. Los pacientes con abdomen agudo representan un grupo microbiológico especial. Objetivos: Hacer una revisión de agentes patógenos en pacientes adultos operados en nuestro Servicio de Urgencia por patología abdominal con líquido libre y analizar los resultados obtenidos de cultivos respecto a las cepas y la susceptibilidad a los antibióticos. Materiales y Método: Estudio de cohorte prospectiva con estadística descriptiva. Se incluyen pacientes consecutivos, mayores de 18 años, operados por abdomen agudo que presentan líquido libre intraperitoneal entre noviembre de 2017 y abril de 2018. Se excluyen casos con terapia antimicrobiana, hospitalización y/o cirugía en los 3 meses previos. Se registran los cultivos positivos, cepas aisladas, susceptibilidad antimicrobiana, datos demográficos y evolución clínica. Resultados: De 63 pacientes 55% fueron hombres, edad promedio 52,2 años. Las patologías más frecuentes fueron de origen apendicular (62%) y de causa entérica (30%). En un 44% el cultivo fue positivo y en 36% con más de un germen. Escherichia coli fue el patógeno más frecuente (64,2%) seguidos de Enterococcus faecium y Streptococcus anginosus (7,1%). De los otros patógenos cultivados sólo se observó resistencia múltiple en un caso aislado de Morganella Morganii. Conclusiones: Estos datos constituyen la realidad microbiológica local en abdomen agudo. La Escherichia Coli sigue siendo el germen más frecuente, debe enfrentarse con profilaxis y tratamiento antibiótico adecuado. Es necesario mantener vigilancia microbiología local para un manejo acorde.
Introduction: It is important to maintain bacterial surveillance programs to decrease resistance and define adequate pharmacological schemes. Patients with abdomen represent a special microbiological group. Objetives: Make a review of pathogens in adult patients operated in our Emergency Service for abdominal pathology with free fluid and analyze the results obtained from cultures with respect to the strains and susceptibility to antibiotics. Materials and Method: Prospective cohort study with descriptive statistics. We include consecutive patients, older than 18 years old, operated on by abdomen who present free intraperitoneal fluid between November 2017 and April 2018. Cases with antimicrobial therapy, hospitalization and/or surgery 3 months prior are excluded. Positive cultures, isolated strains, antimicrobial susceptibility, demographic data and clinical evolution are recorded. Results: Of 63 patients, 55% were men and the average age was 52.2 years. The most frequent pathologies were of appendicular origin (62%) and of enteric origin (30%). In 44% the crop was positive and in 36% with more than one germ. Escherichia coli was the most frequent pathogen (64.2%) followed by Enterococcus faecium and Streptococcus anginosus (7.1%). Of the others, cultivated pathogens have only observed multiple resistance in an isolated case of Morganella Morganii. Conclusions: These data include the local microbiological reality in acute abdomen. Escherichia coli is still the most frequent germ that must be faced with the profile and the appropriate treatment. It is necessary to maintain local microbiology surveillance for a proper management.

Resumen Introducción: Una complicación importante de la cirugía colorrectal es la dehiscencia de anastomosis (DA). El estado nutricional es uno de los factores importantes en la DA. Una forma objetiva para evaluar nutricionalmente a los pacientes es medir la sarcopenia, definida como disminución de masa muscular esquelética, que puede ser objetivada por análisis de Unidades Hounsfield (UH) y área muscular (AM) por medio de Tomografía Computarizada de Abdomen y Pelvis (TCAP). Objetivo: Evaluar si existe relación entre la DA y la presencia de sarcopenia detectada por medición de UH y AM en TCAP en pacientes sometidos a colectomía por cáncer. Materiales y Método: Estudio de casos y controles con estadística analítica. Se eligen de manera aleatoria 21 pacientes con DA y 40 sin DA. Se incluyen > 18 años, con colectomía por cáncer y anastomosis primaria. Fueron excluidos pacientes ostomizados, que no tuvieran TCAP preoperatoria o que éste no permitiera medir UH y AM. La evaluación imagenológica fue realizada por radiólogo experto. Resultados: La comparación entre grupos evidencia que son homogéneos con respecto al sexo (predomino hombres), edad (promedio 60 años) y localización. Se evidencia signos imagenológicos sugerentes de sarcopenia en el grupo de DA, puesto que existe disminución en UH con valores estadísticamente significativos y tendencia a presentar valores menores en el AM. Conclusiones: La presencia de sarcopenia evaluada por alteración de UH en estudio radiológico se correlaciona con DA, pudiendo ser un predictor de riesgo. La importancia de este hallazgo es que es un factor de riesgo potencialmente corregible.
Introduction: An important complication of colorectal surgery is anastomotic dehiscence (AD). Nutritional status is one of the important factors in AD. An objective way to evaluate the patients' nutritional status is to measure sarcopenia, which is the reduction of skeletal muscle mass. It is possible to standardize Sarcopenia using the analysis of the Hounsfield Units (HU) and the muscular area (MA) which consider Computed Tomography of Abdomen and Pelvis (CTAP). Aim: To evaluate whether there is a relationship between AD and the presence of sarcopenia detected by the measurement of HU and MA using CTAP. The situation considers patients undergoing colectomy for cancer. Materials and Method: Cases and controls were studied with analytical statistics. 21 patients with AD and 40 without AD were chosen randomly. They include > 18 years, with colectomy for cancer and primary anastomosis. Ostomized patients, who previous the surgery do not have CTAP or if it was not available to measure HU and MA, were excluded. The imaging evaluation was performed by an expert radiologist. Results: The comparison between groups shows that they are homogeneous with respect the sex (predominant men), age (average 60 years) and location. There are signs of imaging which suggest the presence of sarcopenia in the AD group. This is explained because there is an important statistical decrease in the HU values and a tendency to present lower MA values. Conclusions: The presence of sarcopenia due to alteration of HU in a radiological study is correlated with AD, and could be a predictor of risk. The importance of this finding is that this risk factor is potentially correctable.

To further the use of local parasitoids to control the spotted wing drosophila suzukii (Matsumura) in Mexico, three treatments were implemented by sextuplicate in commercial berry fields of Colima and Jalisco from June 2017 to May 2018: single release of Trichopria drosophilae Perkins (pupal parasitoid), combined release of T. drosophilae + Leptopilina boulardi Barbotin, Carton & Kelner-Pillault (larval parasitoid), and a no release control. Compared with the no release sites, parasitism by T. drosophilae increased 4 and 4.1-fold at the single and combined release sites, respectively, and parasitism of L. boulardi increased 2.8-fold at the sites where it was evaluated. Additionally, it was registered a 50 and 55% reduction of D. suzukii at the sites with single and combined releases, respectively; in other words, supplementing T. drosophilae with L. boulardi provided little benefit compared with the release of T. drosophilae alone. These results indicate that single release of local T. drosophilae is a more cost-effective option to reduce D. suzukii populations, and that such activity can contribute significantly to the phytosanitary management of this invasive pest.

Resumen Introducción: La resección abdominoperineal (RAP) era el tratamiento estándar del cáncer de recto medio o bajo quedando el paciente sin ano y con una ostomía permanente. En los últimos 20 años el desarrollo de nuevas técnicas quirúrgicas, con adecuados resultados quirúrgicos y oncológicos, han permitido ofrecer al paciente la preservación del aparato esfinteriano, sin embargo, éstas pueden presentar problemas de tipo funcional lo que podría derivar en una alteración de la calidad de vida del paciente. Objetivo: Comparar la alteración en la calidad de vida en pacientes sometidos a RAP versus técnicas con preservación de esfínter anal en pacientes operados por cáncer de recto. Materiales y Método: Estudio de cohorte transversal con pacientes operados por cáncer de recto medio-bajo en nuestro hospital entre los años 2009 a 2015. Se utiliza el instrumento EuroQuol-5D2,3 validado en español chileno. Resultados: Se incluyen 39 pacientes, 11 corresponden a colostomía definitiva y 28 a preservación de esfínter. En el análisis por dominios se observaron diferencias significativas en el grupo con ostomía definitiva en el ítem de actividades habituales y a favor de la preservación de esfínter en el ítem sexualidad. Conclusiones: La técnica quirúrgica utilizada en pacientes con cáncer rectal medio-bajo altera la calidad de vida, razón por la cual debe ser adecuadamente seleccionada y además advertir al paciente de las consecuencias que dicha cirugía puede ocasionar.
Introduction: The abdominoperineal resection (APR) was the standard treatment of middle-low rectal cancer, in the last 20 years the development of sparing techniques with sphincter preservation with adequate surgical and oncological results has allowed to offer the patient the sphincter apparatus preservation, avoiding the definitive colostomy, however, these techniques may present secondary incontinence to the loss of the rectum. Both surgical options can affect the quality of life of the patient and this element should be considered. Objective: To compare the change in quality of life of patients undergoing APR vs sphincter preserving techniques in patients operated for rectal cancer. Materials and Method: Cross-sectional cohort study with medium-low rectal cancer patients, operated in our hospital from 2009 to 2015. The instrument EuroQuol-5D2, validated in chilean spanish is used. Results: 39 patients were included (11 definitive colostomy and 28 sphincter preservation). In the analysis by domains, significant differences were observed favor to definitive colostomy in the Item of "Habitual Activities" and favor to sphincter preservation in the Item "Sexuality". Conclusions: In patients with middle-low rectal cancer, the choice of surgical technique have a measurable impact on the patient's quality of life.

INTRODUCTION: It is essential that orthopaedic resident physicians be highly proficient in all aspects, considering the balance between supply, demand, need and context. Fundamental to identify the capacity and quality installed for their training in Mexico. MATERIAL AND METHODS: Observational Study, transverse, non-probabilistic sampling-conglomerates, in two phases. The instrument has 8 domains, 57 variables and 4,867 items. 60 graduate professors of 20 states, 50 hospital sites, 22 university programs. RESULTS: 1,038 years of experience (collective intelligence), 17 years of experience/teacher (01 to 50 years). Identified: acute pathology 30 (2 to 90%), chronic pathology 30 (5 to 96%), patients 15 years, 10 (3 to 30%), patients between 15 and 65 years, 47 (2 to 78%), patients 65 years, 20 (2 to 60%), number of beds/seat 20 (2 to 510), number of clinics 3 (1 to 48), number of surgical procedures/headquarters per year at the national level, was 960 (50 to 24,650). The national average per resident doctor is 362 surgeries/year with 1,450 surgical times/year. CONCLUSIONS: The needs and resources for the training of physicians specializing in orthopedics/traumatology are highly heterogeneous, so it should be adapted to the epidemiological needs of the region of influence, in an area of epidemiological transition. 62.2% expressed not having or have bad academic and scientific infrastructure at its headquarters, more than 50% without rotation overseas and 90% without regular scientific production.
INTRODUCCIÓN: Es fundamental que los médicos residentes de ortopedia (traumatología) sean altamente competentes en todos los aspectos, considerando el equilibrio entre la oferta, demanda, necesidad y contexto. Es primordial identificar la capacidad y calidad instalada para su formación en México. MATERIAL Y MÉTODOS: Estudio observacional, transversal, muestreo no probabilístico-conglomerados, en dos fases. El instrumento tiene ocho dominios, 57 variables y 4,867 ítems. Sesenta profesores de postgrado de 20 estados, 50 sedes hospitalarias, 22 programas universitarios. RESULTADOS: 1,038 años de experiencia (inteligencia colectiva), 17 años de experiencia/profesor (01 a 50 años). Se identificó: patología aguda 30 (2 a 90%), patología crónica 30 (5 a 96%), pacientes 15 años, 10 (3 a 30%), pacientes entre 15 y 65 años, 47 (2 a 78%), pacientes 65 años, 20 (2 a 60%), número de camas/sede 20 (2 a 510), número de consultorios 3 (1 a 48), el número de procedimientos quirúrgicos/sede al año a nivel nacional fue de 960 (50 a 24,650). La media nacional por médico residente es de 362 cirugías/año con 1,450 momentos quirúrgicos/año. CONCLUSIONES: Las necesidades y recursos para la formación de médicos especialistas en ortopedia/traumatología son en alto grado heterogéneos, por lo cual se debería adaptar a las necesidades epidemiológicas de la región de influencia, en un ámbito de transición epidemiológica. Sesenta y dos punto dos por ciento expresó no tener o tener deficiente infraestructura académica y científica en su sede, más de 50% sin rotación al extranjero y 90% sin producción científica regular.

Resumen Tras múltiples intentos para lograr resultados apropiados en una resección quirúrgica por cáncer de recto, Sir William Ernest Miles desarrolla la técnica que posteriormente llevará su nombre, y que se conoce actualmente, sin muchas modificaciones, como resección abdominoperineal. Esta técnica, considerada el gold standard para tumores de recto por muchos años, fue progresivamente reemplazada por las técnicas de preservación de esfínter. La resección anterior baja permitió preservar el esfínter a paciente con tumores de recto a más de 5 cm del margen anal. El desarrollo técnico (suturas grapadas), mejor entendimiento de principios oncológicos (resección total del mesorrecto) y la introducción de la neoadyuvancia con quimioradioterapia, permitió bajar el margen de sección distal considerado adecuado y realizar anastomosis colorrectales ultrabajas y coloanales. La resección ultrabaja interesfintérica reseca el esfínter anal interno (en forma total, subtotal o parcial) logrando evitar la colostomía permanente en un grupo de pacientes. Esta técnica, ha sido ampliamente estudiada con resultados oncológicos publicados que resultan mejores o similares que los de la resección abdominoperineal. Actualmente la evaluación de respuesta a neoadyuvancia, ha llevado a algunos grupos de trabajo a plantear la preservación del órgano; ya sea mediante el seguimiento estricto tras respuesta clínica completa, como técnicas de resección local en respuesta incompleta.
After multiple attempts to achieve appropriate results in the surgical resection for rectal cancer, Sir William Ernest Miles develops the technique that would carry his name, and is, without modifications, currently referred as abdominoperineal resection. This technique, considered gold standard for rectal tumors for many years, has been gradually replaced by sphincter preserving surgery. Low anterior resection allowed sphincter-preservation in patients with low rectal tumors within 5 cm from the anal verge. Technical developments (double stapling technique), better understanding of oncological principles (total mesorectal excision) and the introduction of neoadyuvant treatment with chemoradiotherapy, allowed further lowering of the adequate distal resection margin and to carry out ultralow colorectal and coloanal anastomoses. Ultralow intersphincteric resection removes the internal anal sphincter (partial, subtotal or total resection) avoiding permanent colostomy in a subset of patients. This technique has been broadly studied with published oncological outcomes that are better or similar to those of abdominoperineal resection. Currently, evaluation of response after neoadyuvant therapy has led some working groups to propose organ preservation; either by strict follow up for complete clinical response, or by local excision techniques for incomplete clinical response.

Penile carcinoma is a rare disease that has a wide range of pathology and morbidity. Occurs commonly in the 6th and 7th decades of life. Squamous cell carcinoma (SCC) is the predominant histological type. We present a case of a penile lesion of exophytic papillary morphology accompanied by multiple bilateral mobile inguinal lymph nodes.
