RESUMO
The main event of osteoporosis is fragility fractures. Vertebral compression fractures are the most commonly fragility fracture related to osteoporosis. Our goal is to review the available literature to confirm or deny concepts learned about spinal cementation and adapt our clinical practice according to scientific evidence. In the complex world of spine surgery, constant innovations seek to improve the quality of life of patients. Among these, vertebral augmentation has emerged as an increasingly popular technique, but often shrouded in myths and misunderstandings. In this systematic review, we will thoroughly explore the truths behind vertebral augmentation, unravelling common myths and providing a clear insight into this technique. As specialists in the field, it is crucial to understand the reality surrounding these interventions to offer our patients the best possible information and make informed decisions.
RESUMO
New astronomical observations point to a nucleosynthesis picture that goes beyond what was accepted until recently. The intermediate "i" process was proposed as a plausible scenario to explain some of the unusual abundance patterns observed in metal-poor stars. The most important nuclear physics properties entering i-process calculations are the neutron-capture cross sections and they are almost exclusively not known experimentally. Here we provide the first experimental constraints on the ^{139}Ba(n,γ)^{140}Ba reaction rate, which is the dominant source of uncertainty for the production of lanthanum, a key indicator of i-process conditions. This is an important step towards identifying the exact astrophysical site of stars carrying the i-process signature.
RESUMO
BACKGROUND: Studies on switching to tenofovir alafenamide (TAF)-based regimens raise concerns about a worse metabolic profile in people with HIV, even though most received tenofovir disoproxil fumarate (TDF) in their previous regimen. This study aims to evaluate changes in lipid fractions, glucose, and serum markers for hepatic steatosis (HS) after switching from a TDF- or TAF-sparing regimen to bictegravir/emtricitabine/TAF (B/F/TAF). METHODS: We performed a retrospective cohort study of people with HIV who switched to B/F/TAF from TDF- or TAF-sparing regimens between January 2019 and May 2022 with at least 6 months of follow-up. The primary endpoint was the absolute change in lipid fractions at 6 months. Secondary outcomes were changes in lipid fractions at 12 months and changes in other metabolic parameters (glucose, creatinine, and HS based on the triglyceride-to-glucose [TyG] ratio at 6 and 12 months). Changes were analysed using mixed linear regression models with random intercept and time as a fixed effect. RESULTS: The study included 259 people with HIV (median age 55 [interquartile range (IQR) 47-60] years; 80% male; 88% Caucasian; CD4+ T-cell count 675 [IQR 450-880] cells/mm3; 84.3% HIV-RNA <50 copies/mL). In total, 63 patients (30%) had hypertension, 93 (44%) dyslipidaemia, 30 (14%) diabetes, and 45% obesity/overweight. Most (60%) switched from integrase inhibitor-based regimens, and 21% switched from a boosted regimen. At 6 months, significant reductions were observed in total cholesterol (-7.64 mg/dL [95% confidence interval (CI) -13.52 to -1.76; p = 0.002]), triglycerides (-23.4 [95% CI -42.07 to -4.65]; p = 0.003), and TyG ratio (-0.14 [95% CI -0.23 to -0.05]; p < 0.001). CONCLUSION: In our real-life cohort, the effect of switching TDF-/TAF-sparing regimens to triple therapy with B/F/TAF improved total cholesterol, triglycerides, and serum markers of HS at 6 months and was neutral for the remaining metabolic parameters at 12 months.
RESUMO
Spatial navigation through novel spaces and to known goal locations recruits multiple integrated structures in the mammalian brain. Within this extended network, the hippocampus enables formation and retrieval of cognitive spatial maps and contributes to decision making at choice points. Exploration and navigation to known goal locations produce synchronous activity of hippocampal neurons resulting in rhythmic oscillation events in local networks. Power of specific oscillatory frequencies and numbers of these events recorded in local field potentials correlate with distinct cognitive aspects of spatial navigation. Typically, oscillatory power in brain circuits is analyzed with Fourier transforms or short-time Fourier methods, which involve assumptions about the signal that are likely not true and fail to succinctly capture potentially informative features. To avoid such assumptions, we applied a method that combines manifold discovery techniques with dynamical systems theory, namely diffusion maps and Takens' time-delay embedding theory, that avoids limitations seen in traditional methods. This method, called diffusion mapped delay coordinates (DMDC), when applied to hippocampal signals recorded from juvenile rats freely navigating a Y-maze, replicates some outcomes seen with standard approaches and identifies age differences in dynamic states that traditional analyses are unable to detect. Thus, DMDC may serve as a suitable complement to more traditional analyses of LFPs recorded from behaving subjects that may enhance information yield.

RESUMO
INTRODUCTION AND OBJECTIVES: Carbohydrate antigen 125 (CA125), a biomarker associated with fluid overload, has proven useful in managing diuretic therapy in heart failure. We aimed to evaluate the impact of diuretic optimization guided by CA125 before transcatheter aortic valve implantation (TAVI) on outcomes. METHODS: This prospective interventional study enrolled patients scheduled for TAVI, in whom baseline CA125 was measured 2 weeks before TAVI. Patients with CA125 ≥ 20 U/mL underwent diuretic up-titration before TAVI. Three groups were included: group I) baseline CA125 <20 U/mL; IIa) CA125 ≥ 20 U/mL that decreased after treatment, and IIb) CA125 ≥ 20 U/mL that did not decrease. The primary outcome was changes in the Kansas City Cardiomyopathy Questionnaire at 3 and 12 months. The secondary endpoint was clinical events. RESULTS: The study included 184 patients (115 group I, 46 IIa, and 23 IIb). Groups I and IIa exhibited early and sustained improvements in the Kansas City Cardiomyopathy Questionnaire (group I: 18.9 points [95%CI, 15.7-22.1; P <.001] at 90 days, and 18.1 [95%CI, 14.9-21.4, P <.001] at 1 year; group IIa: 21.1 points [95%CI, 15.4-26.7; P <.001] and 19.5 [95%CI, 13.9-25.1; P <.001] respectively). In contrast, in group IIb there was no significant improvement at 90 days (P=.12), with improvement being significant only at 1 year (17.8 points, 95%CI, 5.9-29.6; P=.003). Over a median follow-up of 20.7 months, there were 63 (27.83%) deaths or heart failure admissions. Multivariate analysis showed a lower risk of events in group I vs IIb (HR, 0.28; 95%CI, 0.14-0.58; P <.001), and IIa vs IIb (HR, 0.24; 95%CI, 0.11-0.55; P <.001). CONCLUSIONS: Patients with persistently high CA125 despite diuretic therapy pre-TAVI showed slower functional recovery and poorer clinical outcomes after TAVI.
RESUMO
RESUMEN Los Niveles de Referencia para Diagnóstico (NRD) son una herramienta dinámica que gana cada vez una mayor importancia para la optimización de las exposiciones médicas. La disponibilidad de información científica es esencial en este proceso de optimización para Medicina Nuclear (MN) y Radiología Diagnóstica (RD). Este trabajo presenta un estudio de la disponibilidad de información sobre los NRD para MN y RD en la base PubMed, en los últimos 20 años, empleando diferentes palabras clave. Se analizó de forma crítica la información disponible, buscando los cambios principales que se han producido como tendencia en diferentes aspectos del establecimiento de los NRD. Se verificó un desbalance significativo en la disponibilidad de literatura científica en estas dos áreas, aunque se ha incrementado la información para equipos híbridos y de forma general para todas las tecnologías. Este desbalance se hace mayor para estudios de medicina nuclear en pediatría. Se observaron avances en la forma de recolectar datos, la manera de organizar la información y analizarla, en especial con la disponibilidad de sistemas de monitoreo de dosis. Se encontró que, en los estudios TC e intervencionismo, las agrupaciones por localización anatómica están siendo acotadas o restringidas, por indicaciones clínicas que tienen similitudes en los requisitos de calidad de imagen para el diagnóstico adecuado. Similarmente en MN se vislumbra la incorporación de la actividad por peso como NRD en las tecnologías híbridas y estudios pediátricos. Este estudio demuestra que, en general, la literatura científica disponible sobre los NRD es mucho más amplia para pacientes adultos. Se requiere más estudios pediátricos, especialmente en el área de MN
ABSTRACT Diagnostic Reference Levels (DRLs) are a dynamic tool that is gaining more and more importance for the optimization of medical exposures. The availability of scientific information is essential in this optimization process for Nuclear Medicine (NM) and Diagnostic Radiology (DR). This work presents a revision of the information's availability about DRL in the PubMed database, in the last 20 years, using different search combinations. The available information was critically analyzed, looking for the main changes that have occurred as a trend in different aspects of the establishment of the NRD. A significant disparity in the amount of information between the two areas on the subject was verified, although there has been an increase of available scientific papers for hybrid equipment, and in general for all technologies. The disparity becomes greater for NM studies in pediatrics population. The way to collect data, the mode to organize the information and analyze it, has also undergone changes, mainly with radiation dose management systems. In CT and interventional studies, the grouping by anatomical locations is being constrained or modulated by clinical indications with analogous image quality requirements for proper diagnosis. Something similar happens in MN, where the incorporation of activity/patient's weight is envisioned as NRD for hybrid technologies and pediatric studies. In general, the study showed that, the scientific paper's availability about DRL for adult population are much wider. More pediatric studies on these subjects are needed, especially in NM

En este estudio formulamos las siguientes preguntas de investigación: ¿cuál es la tasa de supervivencia y falla?, ¿cuáles son los factores de riesgo asociado a falla? y ¿cuáles son los resultados funcionales posterior a la cirugía de reparación meniscal? Material y métodos: estudio ambispectivo desde el 2001 al 2021 de pacientes con lesión meniscal reparable con dispositivos meniscales de sutura todo adentro. La razón de supervivencia y falla se obtuvo con el test de Kaplan-Meier, los factores de riesgo asociado con falla de la sutura meniscal se valoraron con el test de regresión logística y los resultados funcionales pre y postquirúrgicos fueron estimados con la prueba t-Student. Resultados: en 20 años de seguimiento de 316 menisco reparados con suturas meniscal todo adentro se obtuvo que la razón de supervivencia de 95.9%. La ausencia de lesión del cuerno anterior del menisco se mostró como un factor protector [OR = 0.12], junto a la no práctica de deportes de impacto [OR = 0.2]. Se mostraron resultados del IKDC y Tegner-Lysholm posterior a la cirugía de muy buenos a excelentes (p < 0.0001). Conclusión: los dispositivos de sutura de meniscal todo adentro son y seguirán siendo armas de primera línea en la reparación de las roturas meniscales. En 20 años de seguimiento se evidenció una menor tasa de falla, asociados con excelentes resultados funcionales.
Abstract: Introduction: all-in meniscal suture devices have evolved and simplified meniscal repair. In this study we will formulate the following research questions: what is the rate of survival and failure? What are the risk factors associated with failure? And what are the functional results after meniscal repair surgery? Material and methods: ambispective study from 2001 to 2021 of patients with repairable meniscal injury with all-in meniscal suture devices. The survival and failure ratio were obtained with the Kaplan-Meier test, the risk factors associated with meniscal suture failure were assessed with the logistic regression test, and the pre- and post-surgical functional results were estimated with the test. t-Student. Results: in 20 years of follow-up of 316 menisci repaired with all-in meniscal sutures, a survival rate of 95.9% was obtained. The absence of injury to the anterior horn of the meniscus was shown to be a protective factor [OR = 0.12], together with not practicing impact sports [OR = 0.2]. Post-surgery IKDC and Tegner-Lysholm results were shown to be very good to excellent (p < 0.0001). Conclusion: all-in meniscal suture devices are and will continue to be front-line weapons in the repair of meniscal tears. In 20 years of follow-up, a lower failure rate was evidenced, associated with excellent functional results.
RESUMO
El monóxido de carbono es un gas altamente tóxico que se origina principalmente por la combustión incompleta de combustibles fósiles. La intoxicación presenta síntomas inespecíficos que solapan otras patologías y por lo tanto es indispensable la confirmación mediante la medición de la carboxihemoglobina en sangre. El laboratorio incorporó la determinación en el informe del estado ácido base a partir de octubre del 2018, debido a que previamente el médico debía solicitarla frente a la sospecha de una intoxicación. El objetivo del trabajo fue evaluar si esta medida implementada por el laboratorio contribuyó a mejorar el diagnóstico de intoxicación por CO, analizar las características de los pacientes con COHb mayor o igual a 5% y definir un valor de reporte inmediato para la COHb. El 46% de los casos con COHb mayor o igual a 5% no se relacionaban con una intoxicación y/o exposición a CO. De los casos de intoxicación se encontró que el 77% fueron diagnosticados a partir de la sospecha médica y un 23% por hallazgo del laboratorio. Se concluyó que es de mucha utilidad el rol del laboratorio en detectar aquellos casos que no fueron evidentes clínicamente. Existen ciertas patologías como las oncológicas o la enfermedad de Wilson donde se vieron valores elevados de COHb sin presentar intoxicación y se definió finalmente, como valor de reporte inmediato 7% para la COHb. (AU)
Carbon monoxide is a highly toxic gas that originates mainly from incomplete combustion of fossil fuels. Intoxication causes nonspecific symptoms that overlap with other conditions and, therefore, confirmation by measuring blood carboxyhemoglobin is essential. The laboratory incorporated the measurement in the acid-base status report as of October 2018, as it was previously required to be requested by the physician in case of suspected intoxication. The aim of this study was to evaluate whether this measure implemented by the laboratory contributed to the improvement of the diagnosis of CO intoxication, to analyze the characteristics of patients with COHb greater than or equal to 5% and to define an immediate reporting value for COHb. Overall, 46% of the cases with COHb greater than or equal to 5% were not related to CO poisoning and/or exposure. Of the cases of intoxication, 77% were diagnosed based on medical suspicion and 23% on laboratory findings. It was concluded that the laboratory has a useful role in detecting cases that were not clinically evident. There are certain diseases including different types of cancer or Wilson's disease where elevated COHb values were seen without intoxication and finally, 7% for COHb was defined as the immediate reporting value (AU)

La Organización Mundial de la Salud (OMS) informa que ocurren 1.1 millones de casos de tuberculosis (TBC) en niños <15 años. En Chile se observa un aumento de casos en el tiempo. La pandemia por SARS-Cov2 ha implicado una disminución de la pesquisa y un retardo de la atención y diagnóstico de TBC. Se presenta dos casos clínicos de tuberculosis en adolescentes. El primero corresponde a un adolescente con una tuberculosis pulmonar de difícil y tardío diagnóstico, habiéndose descartado inicialmente TBC por estudio molecular y PPD no reactivo. El segundo caso corresponde a un adolescente con una tuberculosis pulmonar y extrapulmonar de diagnóstico tardío, de 8 meses de evolución, posterior a un cuadro leve de Covid.
The World Health Organization (WHO) reports that 1.1 million cases of tuberculosis (TB) occur in children <15 years of age. In Chile, an increase in cases is observed over time. The SARS-Cov2 pandemic has led to a decrease in screening and a delay in care and diagnosis of TB. Two clinical cases of tuberculosis in adolescents are presented. The first corresponds to an adolescent with TB of difficult and late diagnosis, having initially ruled out TB by molecular study and non-reactive PPD. The second case corresponds to an adolescent with pulmonary and extrapulmonary tuberculosis of late diagnosis, of 8 months of evolution, after a mild respiratory infection of Covid.

The outbreak of COVID-19 disease has recently spread from its original place in Wuhan, Hubei province, China, to the entire world, and has been declared to be a pandemic by the World Health Organization in March 2020. All countries in America, in particular Chile, show an important increase in COVID-19 cases and deaths. The clinical manifestations of COVID-19 are a broad spectrum, from asymptomatic mild disease, to severe respiratory failure, shock, multiorgan dysfunction and death. Thus, high clinical suspicion and appropriate structure risk stratification are needed. Health care teams in endoscopy units, are at an increased risk of infection by COVID-19 from inhalation of droplets, mucosae contact, probably contamination due to contact with stools. Endoscopic aerosolized associated infections have also been reported. Different societies' recommendations, have recently placed digestive endoscopy (especially upper) among the high risk aerosol generating procedures (AGPs). In addition, live virus has been found in patient stools. On top of this, the infected health professionals may transmit the infection to their patients. Health care infection prevention and control (HCIPC), has been shown to be effective in assuring the safety of both health care personnel and patients. This is not limited to the correct use of personal protective equipment (PPE), but is based on a clear, detailed and well communicated HCIPC strategy, risk stratification, use of PPE, and careful interventions in patients with moderate and high risk of COVID-19. A conscientious approach regarding limited resources is important, as the simultaneous outbreak in all countries heavily affects the availability of health supplies. The Chilean Gastroenterology Society (SChGE) and Digestive Endoscopy Association of Chile (ACHED) are joining to provide continued updated guidance in order to assure the highest level of protection against COVID-19, for both patients and health care workers. This guideline will be updated online as needed.
El brote de la enfermedad denominada COVID-19, se ha extendido desde su origen en Wuhan, provincia de Hubei, China, a todo el mundo. La Organización Mundial de la Salud lo declaró pandemia en marzo de 2020. Todos los países de América, en especial Chile, presentan incremento de casos y fallecidos. Las manifestaciones clínicas de COVID-19 van desde una enfermedad leve, hasta insuficiencia respiratoria severa, shock, disfunción orgánica y muerte. Se necesita una alta sospecha clínica y una adecuada estratificación del riesgo. El equipo de salud en las unidades de endoscopia, tiene un mayor riesgo de COVID-19 que otras unidades clínicas y de apoyo diagnóstico, dada la mayor exposición a inhalación de gotas, contacto posible con mucosas y contaminación por contacto con deposiciones. Recomendaciones de diferentes sociedades colocan la endoscopia digestiva (especialmente la esofagogastroscopia o endoscopia digestiva alta, EDA) entre los procedimientos generadores de aerosoles (PGA) de alto riesgo. Además, se han encontrado virus viables en las deposiciones de los pacientes. Potencialmente, los profesionales de la salud infectados podrían contagiar a los pacientes. Se ha demostrado que la prevención y control de infecciones asociadas a la atención de salud (IAAS), son efectivos para garantizar la seguridad tanto del personal de salud, como de los pacientes. Esto no es solamente el correcto uso del equipo de protección personal (EPP), sino que se basa en una clara estrategia de IAAS, bien comunicada, con estratificación de riesgo, uso de EPP e intervenciones correctas en pacientes con riesgo moderado y alto. Es relevante un enfoque sobre los limitados recursos, dado la simultaneidad del brote en todos los países, que afecta la disponibilidad de insumos. La Sociedad Chilena de Gastroenterología (SChGE) y la Asociación Chilena de Endoscopia Digestiva (ACHED) publican esta guía actualizada para apoyar las buenas prácticas contra COVID-19, tanto para pacientes como para el equipo de salud. Esta guía podrá tener actualizaciones según avance la información disponible.

A rare case of left-sided gallbladder (sinistraposition) is reported with review of the literature. Left-sided gallbladder is very unusual, with a frequency of 0.3% of the cases, being generally associated to situs inversus. The aim of this invesigation was to establish the association between left-sided gallbladder and right-sided round ligaments. Left-sided gallbladder is a rare anomaly and has been classified into two situations: 1) gallbladder migration to the left side, and 2) development of a second gallbladder with atrophy of the original one. Left-sided gallbladder were reported to be associated with right-sided round ligaments.

Introducción: El 80% de los niños con condiciones médicas crónicas complejas presentan alteración de la conducta alimentaria. Dada la heterogeneidad de los diagnósticos y la complejidad en el manejo de la disfagia pediátrica, es muy importante la intervención de equipos especializados. Objetivo: Evaluación de la evolución de los niños con trastornos de la deglución y/o conducta alimentaria atendidos durante el año 2017 por el equipo interdisciplinario de deglución y conducta alimentaria, del Hospital de Pediatría Juan P. Garrahan. Material y métodos: Estudio analítico, prospectivo y longitudinal con la intervención de un equipo interdisciplinario. Se incluyeron todos los pacientes evaluados durante el año 2017. Se realizó evaluación clínica de la deglución que permitió detectar dificultades durante el momento de la alimentación. Se dieron pautas de estimulación y modificación de consistencias y se derivó a tratamiento oportuno. Se midió porcentaje de destete de soporte nutricional (SN) y/o aumento del aporte por vía oral. Resultados: evaluamos 153 pacientes, 39% mujeres, 90% menores de 3 años de edad y el 75% en apoyo nutricional. El 72% presentó trastorno de la deglución exclusivamente o asociado a trastorno de la conducta alimentaria. El 68% fue seguido en más de una oportunidad. El 36% de los pacientes que ingresaron con requerimiento de SN lograron el destete (sin diferencia significativa entre los que tenían o no trastorno deglutorio p=0.85 y los que tenían o no traqueostomía p=0,88) y 40% aumentó el aporte por vía oral dentro del grupo que no logró el destete. Se observó una diferencia estadísticamente significativa en el destete de los pacientes que concurrieron al espacio de la clínica con respecto a los que no(p=0,016) y mayor tiempo de intervención entre quienes lograron el destete y quienes no, 5,2 ± 3,1 vs 3,45 ± 3,1 meses (p=0,0099). Conclusión: Es esencial el trabajo interdisciplinario y especializado en niños con trastornos de la deglución. La intervención del fonoaudiólogo como parte del equipo es fundamental para una detección precoz y correcto abordaje de la disfagia (AU)
Of all children with chronic complex medical conditions, 80% have eating behavior disorders. Given the heterogeneity of the diagnoses and the complexity of the management of dysphagia in children, intervention of a specialized medical team is essential. Objective: Evaluation of the outcome in children with swallowing and/or eating behavior disorders seen during 2017 by the interdisciplinary group of swallowing and eating behavior disorders at Hospital de Pediatría Juan P. Garrahan. Material and methods: An analytical, prospective and longitudinal study with intervention by an interdisciplinary team. All patients evaluated during 2017 were included. Swallowing was clinically assessed to identify eating disorders. Indications were given for stimulation and food consistency and patients were referred for adequate treatment. The rates of weaning from nutritional support (NS) and/or increase of oral food intake were measured. Results: 153 patients were evaluated, 39% were female, 90% younger than 3 years of age, and 75% AN. Overall, 72% had swallowing difficulties only or associated with an eating behavior disorder; 68% was followed on more than one occasion. Thirty-six percent of the patients who were admitted with NS requirement could be weaned (without a significant difference between those who had a swallowing disorder and those who did not p=0.85 and those that did and did not have a tracheostomy p=0.88) and oral food intake increased in 40% of the patients in the group that could not be weaned. A statistically significant difference was found in the weaning of patients who attended the clinic and those who did not (p=0.016) and longer intervention time between those who could be weaned and those who could not, 5.2 ± 3.1 vs 3.45 ± 3.1 months (p=0.0099). Conclusion: Interdisciplinary and specialized care is necessary for children with swallowing disorders. Intervention of a speech therapist as part of the team is fundamental for the early detection and adequate management of dysphagia (AU)

Resumen OBJETIVO Determinar el perfil clínico y epidemiológico de pacientes con bajas concentraciones de vitamina D atendidas en la consulta externa de endocrinología ginecológica de una institución privada de Medellín, Colombia. MATERIALES Y MÉTODOS Estudio transversal, descriptivo y retrospectivo basado en la revisión de historias clínicas (2013-2014). La información se recolectó en un formulario diseñado ex profeso, se almacenó y analizó en SPSS v.21. Para las variables cuantitativas con distribución normal se calculó el promedio y desviación estándar; para la distribución no normal se estimaron medianas y rangos intercuartílicos; a las variables cualitativas se les estimaron frecuencias absolutas y relativas. RESULTADOS Se analizaron 63 pacientes con mediana de edad de 50 años; 77.8% económicamente activas y 71.4% de estratos socioeconómicos altos. El 50.8% tuvo deficiencia de vitamina D (menos de 20 ng/mL) y 49.2% insuficiencia (20-29.9 ng/mL). El 23.8% de las pacientes recibió suplementos de vitamina D; 7.9% reportó exposición solar significativa y 68.3% usaba bloqueador solar diario. El hipotiroidismo (41.3%), la fatiga crónica (30.2%), la dislipidemia (28.6%) y la osteoporosis (19%) fueron las principales comorbilidades encontradas. CONCLUSIÓN La hipovitaminosis D es relativamente frecuente entre las pacientes que consultan en el servicio de endocrinología ginecológica, lo que supone un aumento en el riesgo de padecer ciertas enfermedades; la prevalencia fue mayor que la reportada para la población general.
Abstract OBJECTIVE To determine the clinical and epidemiological profile of patients with low levels of vitamin D that attended the gynecologic endocrinology consultation of a private institution of Medellin. MATERIALS AND METHODS Cross-sectional, retrospective and descriptive study based on the review of medical records of women older than 18 years who attended the gynecologic endocrinology consultation with low levels of vitamin D. The information was collected by filling out a form designed by the researchers, it was stored and analyzed in SPSS vr.21. Quantitative variables with normal distribution, are expressed as mean with standard deviation; those with non-normal distribution, as median with interquartile range, and qualitative variables as absolute and relative frequencies. This study had the support of the Ethics Committee of the institution. RESULTS 63 women were analyzed, their average age was 50 years, 77.8% were economically active and 71.4% were of the highest socioeconomic status. 50.8% had vitamin D deficiency (<20 ng/mL), while 49.2% had insufficiency (20-29.9 ng/mL). 23.8% of patients were being treated with vitamin D, only 7.9% reported significant sun exposure and 68.3% used sunscreen daily. The main comorbidities were hypothyroidism 41.3%, chronic fatigue 30.2%, dyslipidemia 28.6% and osteoporosis 19%. CONCLUSION Vitamin D deficiency is relatively common among patients who attend the gynecologic endocrinology services, representing an increase in the risk of certain diseases, which shows a higher prevalence than that reported for the general population.
RESUMO
Gestante de 34 semanas de gestación, diagnosticada de preeclampsia con restricción del crecimiento fetal intrauterino. La paciente presentaba alteración en las cifras tensionales con proteinuria positiva en muestra aislada y un índice de proteínas/creatinina en orina de 3.07 mg/mg. Por estos motivos, previa maduración pulmonar, y una vez establecido el tratamiento hipotensor adecuado, se le realizó una cesárea con buena recuperación posterior y normalidad en las cifras tensionales por lo que la paciente fue dada de alta sin precisar tratamiento hipotensor de control. Una semana después del alta, la paciente acude de nuevo al centro hospitalario refiriendo cefalea holocraneal con pérdida de la sensibilidad en el miembro superior derecho. Tras los estudios pertinentes la paciente fue diagnosticada de trombosis del seno sagital superior, iniciándose tratamiento anticoagulante con buena tolerancia al mismo y una recuperación completa del cuadro sin secuelas.
Pregnant 34 weeks gestation diagnosed with preeclampsia with fetal intrauterine growth restriction. The patient had alteration blood presure with positive test of sample isolated proteinuria and an index of protein / creatinine ratio 3.07 mg / mg. For these reasons, previous lung maturation and the antihypertensive treatment was established, a cesárea was realized with good later recovery and normal blood presure. The patient went home without antihypertensive therapy. The patient came to the hospital again a week later, with intense holocraneal headache with loss of sensation in the right arm. After the relevant studies, the patient was diagnosed with thrombosis of the superior sagittal sinus starting anticoagulant therapy with good tolerance to it and a full recovery without sequelae. Pregnancy and specifically puerperium involves stages of risk for development of vascular disease in the brain especially in pathological processes such as preeclampsia. It is important to identify these patients to treat them, also to establish prevention protocols for future pregnancies to help reduce both maternal and fetal morbidity.

BACKGROUND: The use of endoscopic ultrasound with fine needle aspiration (EUS-FNA) has improved the characterization and staging of pancreatic solid masses. The primary strategy for improving the ability to diagnose malignant masses is the use of rapid on site evaluation (ROSE) by a cytopathologist. OBJECTIVE: To evaluate the diagnostic yield of EUS-FNA after the implementation of ROSE in an academic center. MATERIAL AND METHODS: Prospective enrollment and follow-up of EUS-FNA with ROSE during 2015 and 2016, was compared to EUS-FNA without ROSE in previous years (2011-2014) in Hospital Clínico UCChristus. Clinical and endosonographic features, cytopathological and histological diagnosis and number of passes per procedure were evaluated. All EUS-FNA included cytology and cellular block for definitive diagnosis. RESULTS: 59 pancreatic solid masses were included in the analysis. 44 EUS-FNA were performed with ROSE, compared with 15 EUS-FNA without ROSE. The mean age of patients included was 62.8 years, 54.2% male gender, and most masses studied were in the head of pancreas (77.6%). In EUS 86.5% were hypoechoic and 56.9% had poor defined margins. No differences in baseline characteristics were observed between groups. EUS-FNA led to diagnosis in 86.2% of the overall sample. The diagnostic rate was superior in the group of EUS-FNA with ROSE, compared to EUS-FNA without ROSE (97.7% vs 50%, p < 0.0001). The mean number of passes was inferior in EUS-FNA ROSE (+) (2.71 vs 5.78, p < 0.0001). No differences in rate of complications were observed between groups. CONCLUSION: The use of ROSE associated to EUS-FNA improves the diagnostic yield in the evaluation of pancreatic solid masses. Our findings are consistent with those described in the literature, recommending the use of ROSE in EUS-FNA in centers where the diagnostic yield is less than 90% without the use of ROSE
INTRODUCCIÓN: La adquisición de tejido mediante el uso de endosonografía, con punción con aguja fina, (EUS-FNA) ha mejorado el diagnóstico de lesiones pancreáticas sólidas. La principal medida para aumentar el rendimiento diagnóstico de la EUS-FNA es la evaluación por citopatólogo próximo al lugar de punción (in situ) (técnica conocida en inglés como ROSE "rapid on-site evaluation"). OBJETIVO: Evaluar el rendimiento diagnóstico de EUS-FNA en lesiones pancreáticas sólidas posterior a la implementación de ROSE en un centro universitario. MATERIAL Y MÉTODOS: Registro prospectivo de EUS-FNA realizadas con ROSE durante el período 2015-2016, comparado con EUS-FNA con evaluación histopatológica diferida realizada entre los años 2011-2014, en Hospital Clínico UC-Christus. Se evaluaron características clínicas, endosonográficas, diagnóstico histopatológico y número de pases por procedimiento. Todas las EUS-FNA incluyeron citología y block celular para diagnóstico definitivo. RESULTADOS: Se incluyeron en el análisis 59 lesiones pancreáticas sólidas evaluadas con EUS-FNA. Seguimiento prospectivo de 44 EUS-FNA con ROSE, que fueron comparadas con 15 EUS-FNA sin evaluación in situ (retrospectivo). La muestra total incluyó individuos con un promedio de 62,8 años de edad, 54,2% hombres, donde 77,6% de las lesiones se ubicaba en la cabeza pancreática. Endosonográficamente 86,5% de las lesiones eran hipoecoicas y 56,9% tenían márgenes poco definidos. La EUS-FNA fue diagnóstica en 86,2% del total de la muestra. Las EUS-FNA realizadas con ROSE presentaron un mayor rendimiento diagnóstico respecto a las efectuadas sin evaluación in situ (97,7% vs 50%, p < 0,0001). El número de pases por procedimiento fue menor (2,7% vs 5,8%, p < 0,0001) en el grupo con ROSE. No hubo diferencias en complicaciones en ambos grupos. CONCLUSIÓN: La evaluación por citopatólogo in situ de la muestra obtenida por EUS-FNA mejora el rendimiento diagnóstico de las lesiones pancreáticas sólidas. Nuestros hallazgos apoyan el uso de ROSE asociado a EUS-FNA, siendo concordantes con las recomendaciones actuales de utilizar evaluación histopatológica in situ en EUS-FNA, especialmente en centros donde el rendimiento diagnóstico sin uso de ROSE es menor a 90%.
