RESUMO
ABSTRACT: Liver-directed percutaneous and endovascular therapies are effective methods to diagnose and treat various hepatic disorders and malignancies. Because of the close anatomic proximity of the liver to the right hemidiaphragm, pleura, and lung bases, complications can arise involving these structures. Although they are rare, awareness of intrathoracic complications associated with liver-directed therapies and their imaging features will ensure timely detection and management. We aim to review the clinical and imaging features of thoracic complications related to liver-directed therapy and interventions.

Resumen Objetivo: Analizar el efecto y la percepción de una intervención digital, basada en atención plena para disminuir el estrés y ansiedad generalizada entre los trabajadores de la Universidad Veracruzana (UV). Materiales y Métodos: Un ensayo clínico aleatorizado se llevó a cabo con 102 participantes, divididos en un grupo experimental y un grupo control para evaluar el efecto de una intervención a través de WhatsApp, en la reducción del estrés y la ansiedad. El grupo experimental recibió un programa de meditación con el fin de capacitarlos y enseñarles a practicar la atención plena. Se utilizaron las escalas de estrés percibido PSS-10 y del trastorno de la ansiedad generalizada GAD-7 para evaluar el efecto de la intervención. Los participantes expresaron su opinión sobre la intervención mediante entrevistas focalizadas con preguntas estandarizadas. Resultados: Se encuentra una disminución en las medianas del nivel de estrés percibido y ansiedad generalizada del grupo experimental entre el momento pre-intervención y post-intervención, con una diferencia estadísticamente significativa, p=0.012 y p=0.013, respectivamente. En el grupo control se visualiza un ligero aumento en dichos niveles y no se identifican diferencias significativas entre la medición basal y final, tanto en estrés como en ansiedad. En el análisis del espectro del discurso, se examinó la categoría de "Usabilidad" y se identificaron diferentes aspectos relacionados con la percepción, participación y recomendación de la intervención. Conclusiones: Se encontró una mejoría estadísticamente significativa en los niveles de estrés y ansiedad generalizada. Se demuestra que, realizar intervenciones en salud pública que involucren la tecnología, es cada vez más adaptable y contribuye al avance del conocimiento dentro del autocuidado de la salud mental entre los trabajadores de la Universidad Veracruzana.
Abstract Objective: To analyze the effect and perception of a digital intervention, based on mindfulness to reduce stress and generalized anxiety among workers at the Universidad Veracruzana (UV). Materials and Methods: A randomized clinical trial was carried out with 102 participants, divided into an experimental group and a control group to evaluate the effect of an intervention through WhatsApp in reducing stress and anxiety. The experimental group received a meditation program in order to train and teach them to practice mindfulness. The PSS-10 Perceived Stress and GAD-7 Generalized Anxiety Disorder scales were used to assess the effect of the intervention. Participants expressed their opinion about the intervention through focused interviews with standardized questions. Results: There is a decrease in the median level of perceived stress and generalized anxiety of the experimental group between the pre-intervention and post-intervention moments, with a statistically significant difference, p=0.012 and p=0.013, respectively. In the control group, a slight increase in said levels was observed and no significant differences were identified between the baseline and final measurement, both in stress and anxiety. In the discourse spectrum analysis, the "Usability" category was examined and different aspects related to the perception, participation and recommendation of the intervention were identified. Conclusions: A statistically significant improvement was found in the levels of stress and generalized anxiety. It is shown that carrying out public health interventions that involve technology is increasingly adaptable and contributes to the advancement of knowledge within mental health self-care among workers at the Universidad Veracruzana.
RESUMO
Cystic mediastinal masses have traditionally represented a diagnostic dilemma with differentiation of malignant masses a particular area of concern. Each imaging modality has strengths and weaknesses in mediastinal imaging-computed tomography (CT) offers increased spatial resolution at the cost of poorer soft tissue differentiation and requiring ionizing radiation, while magnetic resonance imaging (MRI) offers superior soft tissue contrast/characterization at significantly greater cost. Ultrasound offers real-time visualization but is operator and tissue dependent. [18F]fluoro-D-glucose (F-18 FDG) positron emission tomography (F-18 FDG PET) CT provides functional information, but poorer spatial resolution. Recent advances have focused upon the use of magnetic resonance imaging to aid in characterization of cystic mediastinal lesions, particularly in the context of indeterminate CT findings. The mediastinum may be divided into three anatomic compartments: prevascular, visceral, and paravertebral. All three compartments extend superiorly from the thoracic inlet and inferiorly to the diaphragm. These compartments provide a useful framework for categorizing normal and pathologic mediastinal processes. In this article, we will review the imaging characteristics of mediastinal cystic lesions via a case-based review divided by anatomical mediastinal compartments. Characteristic imaging features and troubleshooting are particular areas of focus. Normal variants that may mimic cystic pathology are discussed. The roles of CT and MRI will be emphasized. Cases from our institution are presented as illustrative examples.
RESUMO
Resumen Objetivos: en Colombia se ha venido implementando la sedación por médicos no anestesiólogos para procedimientos endoscópicos fuera del quirófano. Se describió la experiencia en la unidad de gastroenterología de una clínica de alto nivel de atención en Cali, Colombia. Materiales y métodos: estudio observacional, de tipo cohorte analítica para describir la frecuencia y el tipo de eventos adversos asociados a los procedimientos de sedación por médicos generales, y evaluar los factores asociados a su ocurrencia en pacientes que acudieron a la unidad de endoscopia de la Fundación Valle del Lili para la realización de estudios endoscópicos bajo sedación intravenosa que, por ser de bajo riesgo, fue aplicada por un médico no anestesiólogo entre noviembre de 2018 y junio de 2019. Se realizó análisis descriptivo, se calcularon mediana y rango intercuartílico para las variables numéricas, y frecuencias para las variables cualitativas. Resultados: se incluyeron 1506 participantes, 59,4 % ASA I y 40,6 % ASA II. En promedio, la dosis inicial de propofol fue de 60 mg y la dosis total, de 140 mg. Se registraron eventos adversos no serios en 46 pacientes (3,05 %) y el más común fue la desaturación transitoria (80,4 %). Ningún paciente presentó eventos adversos serios. El puntaje inicial promedio de la escala de Aldrete fue 8, mientras que al alta el puntaje promedio fue de 10. Conclusiones: la sedación para procedimientos endoscópicos dada por médicos no anestesiólogos es segura, siempre y cuando sea realizado por personal entrenado que realice una adecuada valoración de los antecedentes (cardiovasculares, gastrointestinales y neurológicos) y factores de riesgo del paciente dentro del marco de los lineamientos institucionales vigentes.
Abstract Objectives: in Colombia, sedation by non-anesthesiologists for endoscopic procedures outside the operating room has been implemented. A description of an experience in the gastroenterology unit of a tertiary referral hospital in Cali, Colombia, was conducted. Materials and methods: an analytical cohort observational study to describe the frequency and type of adverse events associated with sedation procedures performed by general practitioners and evaluate the factors related to their occurrence in patients who attended the endoscopy unit of Fundación Valle del Lili for endoscopic studies under intravenous sedation. Between November 2018 and June 2019, non-anesthesiologist physicians performed this procedure due to the minimal risk implied. A descriptive analysis was completed, and the median and interquartile range were calculated for numerical variables and frequencies for qualitative variables. Results: There were 1506 participants, 59.4% ASA I and 40.6% ASA II in this study. On average, the starting dose of propofol was 60 mg, and the total dose was 140 mg. Forty-six patients (3.05%) reported non-severe adverse events; the most common occurrence was transient desaturation (80.4%). No patients experienced severe adverse events. The average initial Aldrete scale score was 8, while at discharge, the average score was 10. Conclusions: sedation for endoscopic procedures performed by non-anesthesiologists is safe provided that it is performed by trained personnel conducting a correct assessment of the patient's (cardiovascular, gastrointestinal, and neurological) history and risk factors within the framework of the current institutional guidelines.
RESUMO
INTRODUCTION: Young women under 30 years with breast cancer (BC) are an emerging challenge. The purpose is to identify prognostic factors for survival in young women under 30 years of age with BC. MATERIAL AND METHODS: A retrospective cohort study was conducted among women younger than or equal to 40 years with BC and who were treated at the State Cancer Center during the period 2012-2017. Overall survival was assessed using the Kaplan-Meier method and the log-rank test. Univariate and multivariate analysis assessed survival predictors using Cox proportional hazards regression model. RESULTS: 282 young women were included. The >30-year-old subgroup showed a significant association with excess weight (P = .002) compared to the <30-year-old group. The <30-year-old subgroup showed a poor overall survival (56.7%), as well as highly significant values in advanced clinical stages, metastatic nodules, metastasis, and neoadjuvant therapy (P < .001). In Model 3 of the multivariate analysis, age <30 years (HR = 3.0; 95% CI 1.1 to 8.6), triple negative subtype (HR = 2.6; 95% CI 1.1 to 6.0), tumor size >5 cm HR = 2.3; 95% CI 1.03 to 5.1), and advanced clinical stages (HR = 6.6 95% CI 1.3 to 35.5) persisted as predictors. CONCLUSIONS: Being very young (<30 years) is a predictor for limited survival compared to the age of 30-40 years, as well as the tumor covariates for a worse prognosis: triple negative subtype, advanced stages, positive lymph nodes, and distant metastases in liver.

OBJECTIVE: This paper aims to assess diet and lifestyle by designing a healthy behavior index (HBI) related to the educational level and time of breast cancer (BC) diagnosis. METHODS: 241 female breast cancer survivors treated at Centro Estatal de Cancerología (State Cancer Center) in Mexico were assessed based on dietary pattern, physical activity, smoking, alcohol consumption, body size and shape, sleep disorders with increasing scores that represent less healthy characteristics. The odds ratios (OR) and quartiles of the healthy behavior index and the time of diagnosis were estimated. The regression model was used to assess the association between HBI and the BC covariates. RESULTS: The healthy behavior index for the two first quartiles was that of p < 0.001. The graphic behavior of correspondence with the covariates (age, schooling and moderate physical activity) showed a different three-dimensional effect on healthy behaviors. According to diagnosis time ≤ three years, the following covariates were significant: socioeconomic status, (OR: 4.34 CI 95% 1.2-9.5), sleep disturbances (p = 020) and protective intake of fruits and vegetables (p = 0.001). In the multivariate analysis, survivors with a high level of education are significantly more likely to show a healthy behavior (OR: 0.3 95% CI 0.12 - 0.8); as well as the early clinical stages (OR: 0.4 95% CI 0.2-0.9). CONCLUSION: In breast cancer survivors, both the high level of education and early clinical stages were important healthy behavior modifiers. PRACTICE IMPLICATIONS: Since diets are potentially modifiable, the findings may have further implications to promote a careful dietary pattern to prevent breast cancer. These variables should be assessed as a strategy in cancer survivor preventive programs.

BACKGROUND: Detection and management of neglected tropical diseases such as cutaneous leishmaniasis present unmet challenges stemming from their prevalence in remote, rural, resource constrained areas having limited access to health services. These challenges are frequently compounded by armed conflict or illicit extractive industries. The use of mobile health technologies has shown promise in such settings, yet data on outcomes in the field remain scarce. METHODS: We adapted a validated prediction rule for the presumptive diagnosis of CL to create a mobile application for use by community health volunteers. We used human-centered design practices and agile development for app iteration. We tested the application in three rural areas where cutaneous leishmaniasis is endemic and an urban setting where patients seek medical attention in the municipality of Tumaco, Colombia. The application was assessed for usability, sensitivity and inter-rater reliability (kappa) when used by community health volunteers (CHV), health workers and a general practitioner, study physician. RESULTS: The application was readily used and understood. Among 122 screened cases with cutaneous ulcers, sensitivity to detect parasitologically proven CL was >95%. The proportion of participants with parasitologically confirmed CL was high (88%), precluding evaluation of specificity, and driving a high level of crude agreement between the app and parasitological diagnosis. The chance-adjusted agreement (kappa) varied across the components of the risk score. Time to diagnosis was reduced significantly, from 8 to 4 weeks on average when CHV conducted active case detection using the application, compared to passive case detection by health facility-based personnel. CONCLUSIONS: Translating a validated prediction rule to a mHealth technology has shown the potential to improve the capacity of community health workers and healthcare personnel to provide opportune care, and access to health services for underserved populations. These findings support the use of mHealth tools for NTD research and healthcare.

BACKGROUND/OBJECTIVE: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) may involve the kidney, respiratory tract, skin, or central and peripheral nervous system. Reports of interstitial lung disease (ILD) in AAV (AAV-ILD) have been increasing. METHODS: We reviewed the medical records of all patients with AAV-ILD between January 1, 2007, and December 31, 2017, and compared their pulmonary involvement to patients with idiopathic pulmonary fibrosis (IPF). RESULTS: We identified 24 patients with AAV-ILD: 14 with microscopic polyangiitis, 8 with granulomatosis with polyangiitis, and 2 with eosinophilic granulomatosis with polyangiitis. Perinuclear or myeloperoxidase ANCA was present in 16 cases (66.7%), whereas cytoplasmic or proteinase 3 ANCA was positive in 8 (33.3%). Usual interstitial pneumonia (UIP) was seen in 11 (45.8%), probable UIP in 1 (4.2%), indeterminate UIP in 2 (8.3%), and an alternate diagnosis in 10 (41.7%), and was further characterized as chronic hypersensitivity pneumonitis-like pattern seen in 6 (25%), nonspecific interstitial pneumonia-like pattern in 3 (12.5%), and cryptogenic organizing pneumonia-like pattern in 1 (4.2%). Forced vital capacity and diffusing capacity declined over time in patients with AAV-ILD. When compared with the IPF cohort, patients with AAV-ILD had intermediate survival and speed of lung function decline (3-year survival in AAV-ILD group was 94% vs 69% in IPF). CONCLUSIONS: Antineutrophil cytoplasmic antibody-associated vasculitis ILD is a progressive and potentially fatal condition. Although most cases in the literature are associated with p-ANCA and positive myeloperoxidase, we found that a third of patients had c-ANCA or granulomatosis with polyangiitis. Our cohort adds experience in this rare manifestation of AAV.

Smooth muscle conditions of the chest have diverse clinical and imaging manifestations and may involve nearly every thoracic structure. Differentiation among these conditions requires the integration of clinical, radiologic, and histopathologic data. Histologic examination in conjunction with immunohistochemistry is essential for differentiation from other spindle cell neoplastic mimics. Familiarity with these entities will ensure the inclusion of smooth muscle conditions in the differential diagnosis of thoracic soft tissue lesions and potentially guide the clinician in appropriate management. We review the clinical, imaging, and histopathologic features of thoracic smooth muscle-related conditions organized by the anatomic structures affected.

BACKGROUND: Cardiac myxomas are common and account for 50% of primary intracardiac tumors. Atypical locations of cardiac myxoma increase the risk of intraoperative iatrogenic injuries. Herein, we report a case of using three-dimensional printing (3D) to facilitate the removal of an atypical cardiac myxoma in a 63-year-old woman. METHODS AND RESULTS: Mass in the high posterior atrial septum was confirmed through imaging. Due to the potential involvement of the mass to surrounding vital structures, 3D printing of the cardiac mass was performed. The tumor was completely resected via median sternotomy and the resulting defect was repaired with the bovine pericardium. The patient had an uncomplicated postoperative course except for the development of sick sinus syndrome. One-year follow-up showed no tumor recurrent. CONCLUSION: 3D printing technology in patients with atypical cardiac tumors enhances our understanding of the extent of the tumor invasion and facilitates planning the operation to avoid intraoperative complications.

Resumen Introducción: en América Latina, la enfermedad inflamatoria intestinal (EII) es poco frecuente y la información, limitada. Se describieron características de los pacientes con EII en una unidad de gastroenterología de una clínica de alto nivel de atención en Cali, Colombia. Materiales y métodos: estudio descriptivo de pacientes que consultaron con diagnóstico de enfermedad de Crohn (EC) o colitis ulcerativa (CU) a la Clínica Fundación Valle del Lili entre enero de 2011 y diciembre de 2015. Se realizó un análisis con Statistical Package for the Social Sciences de IBM (SPSS) versión 19, se calcularon la mediana y el rango intercuartílico para las variables numéricas, y frecuencias para las variables cualitativas. Resultados: se incluyeron 416 participantes, 115 con EC y 301 con CU. El 41 % se clasificó como enfermedad leve, 23,5 % moderada y 35,3 % grave. Se realizó cirugía a 24 pacientes (9,0 %) con CU y 53 (46,1 %) con EC. En esta última, el manejo más frecuente fue los medicamentos biológicos (32,2 %), seguidos de inmunomoduladores (27,8 %), esteroides (20 %) y ácido 5-aminosalicílico (5-ASA) (11,3 %). El tratamiento más frecuente de CU fue 5-ASA (84,8 %), seguido de esteroides (32,19 %), azatioprina (24,6 %) y biológicos (15,9 %). Conclusiones: el diagnóstico precoz sigue siendo un reto. La gravedad de la CU en los pacientes estudiados fue menor a la reportada en el mundo, lo cual no ocurrió con los pacientes con EC y podría estar en relación con el retraso diagnóstico. El uso de medicamentos biológicos se acercó a lo reportado en el primer mundo. Es difícil determinar si las menores tasas de cirugía se deben a una mejor respuesta clínica o a un difícil acceso a estas intervenciones.
Abstract Objectives: In Latin America, inflammatory bowel disease (IBD) is rare, and information about it is limited. This article describes characteristics of IBD patients in a gastroenterology unit at a high-level clinic in Cali, Colombia. Materials and methods: This is a descriptive study of patients diagnosed with Crohn's disease (CD) or ulcerative colitis (UC) at the Clínica Fundación Valle de Lili between January 2011 and December 2015. Statistical analysis was performed with SPSS version 19. Medians and interquartile ranges were calculated for numerical variables. Frequencies were calculated for qualitative variables. Results: The 416 participants included 115 with CD and 301 with UC. Of the total cases, 41% were classified as mild, 23.5% as moderate and 35.3% as severe. Surgery was performed in 24 patients (9.0%) with UC and 53 (46.1%) with CD. CD was most frequently managed with biologicals (32.2%), followed by immunomodulators (27.8%), steroids (20%) and 5-ASA (11.3%). The most frequent treatment for UC was 5-ASA (84.8%), but 32.19% received steroids, 24.6% received azathioprine and 15.9% received biologicals. Conclusions: Early diagnosis remains a challenge. The severity of UC but not CD in the patients studied was less than that reported elsewhere in the world. The difference could be related to diagnostic delay. The use of biologicals was close to that reported in the first world. It is difficult to determine if lower surgery rates are due to better clinical response or to difficult access to these interventions.

BACKGROUND: The body mass index (BMI) is the most commonly used anthropometric indicator. However, it does not discern among the different body components. The body fat content, expressed as fat mass index (FMI), is an accurate way to estimate adiposity. Since most metabolic diseases are associated with excess fat tissue, our aims were to comparatively analyze the frequency of associated metabolic abnormalities in patients with different obesity degrees based on BMI and FMI and to determine the best cut-off value of both indicators to predict metabolic abnormalities. METHODS: From a cohort of 2007 patients, BMI and FMI were calculated using DXA. Individuals were classified into the different obesity degrees according to the reference ranges from the World Health Organization (WHO) and the National Health and Nutrition Examination Survey (NHANES). A comparative analysis between BMI, FMI, and their correlation to the presence of metabolic alterations was performed. RESULTS: BMI underestimated the degree of obesity when compared with FMI. Spearman's rank-order correlation for both indexes resulted in very high coefficients (rho Spearman's = 0.857; p = 0.0001). The prevalence of metabolic alterations increased as BMI and FMI also increased. Despite the high positive statistical correlation between BMI and FMI, it was seen that some comorbidities were more specifically related to one particular index. CONCLUSIONS: There were no significant differences between the BMI and the FMI for predicting the degree of obesity. Likewise, there were no significant differences between them for the prediction of metabolic alterations.

Abstract Aim: To assess the risk of tuberculosis (infection and disease) in children less than 15 years' old who are household contacts of pulmonary tuberculosis patients in three Colombian cities (Medellín, Cali, and Popayán). Methods: A cohort of 1,040 children household contacts of 380 adults with smear-positive pulmonary tuberculosis was followed up for 24 months. Study period 2005-2009. Results: Tuberculin skin test was positive (≥10 mm) in 43.7% (95% CI: 39.2-48.2). Tuberculin skin test positivity was associated with age 10-14 years (Prevalence Ratio -PR= 1.43, 95% CI: 1.1-1.9), having a BCG vaccine scar (PR= 1.52, 95% CI: 1.1-2.1), underweight, closer proximity to the index case and exposure time >3 months. The annual risk of infection (tuberculin skin test induration increase of 6 mm or more per year) was 17% (95% CI: 11.8-22.2) and was associated with a bacillary load of the adult index case (Relative Risk -RR= 2.12, 95% CI: 1.0-4.3). The incidence rate of active tuberculosis was 12.4 cases per 1,000 persons-year. Children <5 years without BCG vaccine scar had a greater risk of developing active disease (Hazard Ratio -HR= 6.00, 95% CI: 1.3-28.3) than those with scar (HR= 1.33, 95% CI: 0.5-3.4). The risk of developing active tuberculosis augmented along with the increase from initial tuberculin skin test (tuberculin skin test 5-9 mm HR= 8.55, 95% CI: 2.5-29.2; tuberculin skin test ≥10 mm HR= 8.16, 95% CI: 2.0-32.9). Conclusions: There is a need for prompt interruption of adult-to-children tuberculosis transmission within households. Conducting proper contact investigation and offering chemoprophylaxis to infected children could reduce tuberculosis transmission.
Resumen Objetivo: Evaluar el riesgo de tuberculosis (infección y enfermedad) en niños menores de 15 años de edad convivientes de pacientes con tuberculosis pulmonar en tres ciudades colombianas (Medellín, Cali y Popayán). Métodos: Se siguió durante 24 meses una cohorte de 1,040 niños convivientes de 380 adultos con tuberculosis pulmonar bacilífera. Periodo de estudio 2005-2009. Resultados: La prueba de tuberculina fue positiva (≥10 mm) en el 43.7% (IC 95%: 39.2-48.2), y estuvo asociada con la edad de 10-14 años (Razón de Prevalencia-RP= 1.43, IC 95%: 1.1-1.9), tener cicatriz de la vacuna BCG (RP= 1.52, IC 95%: 1.1-2.1). El riesgo anual de infección (aumento de la induración en la prueba de tuberculina de 6 mm o más al año) fue 17% (IC 95%: 11.8-22.2), y estuvo asociado con mayor carga bacilar en el adulto con tuberculosis pulmonar (Riesgo Relativo-RR= 2.12, IC 95%: 1.0-4.3). La tasa de incidencia de tuberculosis activa fue de 12.4 casos por 1,000 años-persona de seguimiento. Los niños menores de 5 años sin cicatriz de vacuna BCG tuvieron un mayor riesgo de desarrollar tuberculosis activa (Razón de Peligro -HR= 6.00, IC 95%: 1.3-28.3), que quienes tenían cicatriz (HR= 1.33, IC 95%: 0.5-3.4). El riesgo de desarrollar tuberculosis activa aumentó conforme el aumento de la prueba de tuberculina inicial (prueba de tuberculina 5-9 mm HR= 8.55, IC 95%: 2.5-29.2; prueba de tuberculina ≥10 mm HR= 8.16, IC 95%: 2.0-32.9). Conclusión: Es necesario interrumpir rápidamente la transmisión de tuberculosis de adultos a niños en los hogares. Realizar investigaciones de contacto apropiadas y ofrecer quimioprofilaxis a los niños infectados podría reducir la transmisión de la tuberculosis.

Organizing pneumonia is a recognized complication after external beam radiotherapy of breast and lung cancer but has not been described after radioembolization. A 67-year-old female who underwent ablative trans-arterial radioembolization for the treatment of hepatic metastatic renal cell carcinoma adjacent to the diaphragm presented with computed tomography findings of asymptomatic organizing pneumonia in the lower lobes. A follow-up computed tomography 8 months after conservative management demonstrated near-total resolution of the previous pulmonary parenchymal disease. The patient continues to remain asymptomatic and shows no evidence of residual tumor 10 months after radioembolization.
RESUMO
Resumen Introducción: en Colombia, la infección por el virus de la hepatitis C (VHC) representa alta morbilidad y elevados costos. Con la llegada de nuevos tratamientos más efectivos, se hace necesario conocer las características propias de esta población para su adecuado uso. Objetivos: describir las características epidemiológicas y clínicas de los pacientes con VHC manejados en un centro de referencia en enfermedades hepáticas. Materiales y métodos: se realizó un estudio descriptivo de corte transversal en una población de adultos con diagnóstico serológico de VHC entre el 2011 y el 2016. Resultados: se evaluaron 214 historias clínicas de pacientes con diagnóstico serológico confirmado de VHC. La mediana de edad fue de 59 años y el 62 % fue de sexo femenino. El genotipo se reportó en 114 pacientes, el 75 % presentó genotipo 1B. El 36,9 % de los pacientes había recibido algún hemoderivado y el 5 % tenía tatuajes. La prevalencia de cirrosis fue del 29,4 % y de hepatocarcinoma fue del 3,3 %. El 1,8 % y el 5,1 % de los pacientes presentó coinfección con el virus de la hepatitis B (VHB) y virus de la inmunodeficiencia humana (VIH), respectivamente. Conclusión: los factores determinantes de la infección por el VHC en Cali presentan un comportamiento clínico similar al que reporta la literatura científica a nivel mundial, lo que obliga a enfatizar en la prevención de la población en riesgo. El genotipo 1B continúa siendo el más frecuente en nuestro medio, lo que hace a esta población susceptible a los nuevos tratamientos.
Abstract Introduction: In Colombia, Hepatitis C virus infections have high rates of morbidity and high costs. The advent of new more effective treatments has produced a need for better knowledge of this population's characteristics to allow their proper use. Objectives: The objective of this study is to describe the epidemiological and clinical characteristics of patients with hepatitis C at a referral center for liver diseases. Materials and methods: We conducted a cross-sectional descriptive study of a population of adults with serological diagnoses of hepatitis C between 2011 and 2016. Results: We evaluated 214 clinical records of patients with confirmed serological diagnoses of hepatitis C. Their median age was 59 years, and 62 % were women. The HCV genotypes of 114 patients were reported: 75 % had genotype 1B. Transfusions of one or another type of blood product had been administered to 36.9 % of the patients, and 5% had tattoos. The prevalence of cirrhosis was 29.4 % while that of hepatocellular carcinoma was 3.3 %. Hepatitis B virus coinfections were found in 1.8 % of these patients, and 5.1 % of the patients had human immunodeficiency virus coinfections. Conclusion: The determinants of hepatitis C virus infection in Cali are similar to those reported in scientific literature worldwide and requires emphasis on prevention in the at-risk population. Genotype 1b continues to be the most frequent in our environment which makes this population susceptible to new treatments.

Introducción. El dengue, transmitido principalmente por Aedes aegypti, es una enfermedad viral de gran importancia en salud pública. Colombia es un país endemoepidémico para el dengue y, en ciudades como Medellín, hay barrios con alta y baja incidencia. Las diferencias en cuanto a los conocimientos, las prácticas y los aspectos entomológicos podrían estar determinando la dinámica de la enfermedad en los barrios. Objetivo. Determinar los conocimientos y prácticas en torno al dengue de los habitantes de barrios con alta y baja incidencia y explorar los aspectos entomológicos relacionados con la presencia del vector. Materiales y métodos. Se hizo un estudio transversal y se compararon dos barrios con alta incidencia y dos con baja incidencia durante el trienio de 2013 a 2015. Se seleccionó una muestra aleatoria de 100 viviendas por barrio para evaluar los conocimientos, las prácticas y los aspectos entomológicos. Se hicieron el análisis descriptivo, el bivariado y el multivariado (regresión logística). Resultados. En los barrios con alta incidencia, los participantes se caracterizaron por no haber realizado estudios o haber cursado únicamente primaria (odds ratio, OR=1,69; IC95%=1,09-2,63), así como por pertenecer al régimen subsidiado del sistema de seguridad social en salud o no estar afiliado (OR=2,16; IC95% 1,41-3,32) y, además, presentaron un mayor conocimiento del vector (OR=1,53; IC95% 1,00-2,35). En cuanto a las prácticas, la posibilidad de encontrar viviendas en donde se almacenaba el agua fue mayor (OR=1,69; IC95% 1,11-2,57) y, en lo relacionado con los aspectos entomológicos, se encontraron más viviendas con mosquitos adultos (OR=2,13; IC95% 1,29-3,50). Conclusiones. En este estudio se encontraron diferencias importantes entre los barrios en cuanto a los conocimientos, las prácticas y la presencia de estados adultos del vector, lo cual contribuye a explicar la epidemiología del dengue en estos lugares.
Introduction: Dengue, mainly transmitted by Aedes aegypti, is a very important viral disease in terms of public health. Colombia is an endemoepidemic country for dengue and, in cities like Medellín, there are neighborhoods with high and low incidence. The disease dynamics in the neighborhoods might be determined by differences in the knowledge, practices and entomological aspects of the vector among the communities. Objective: To identify the knowledge and practices of residents of neighborhoods with high and low incidence of dengue, and to explore the entomological aspects related to the presence of the vector. Materials and methods: We conducted a cross-sectional study comparing two neighborhoods with high incidence and two with low incidence during the triennium of 2013-2015. A random sample of 100 houses per neighborhood was selected in order to evaluate the knowledge, practices and entomological aspects related to dengue. In addition, descriptive, bivariate and multivariate analyses (logistic regression) were performed. Results: In neighborhoods with high incidence, participants had not attended school or had only a primary school level of education (OR=1.69; 95% CI: 1.09-2.63). Additionally, they did not have health coverage or belonged to the subsidized regime (OR=2.16; 95% CI: 1.41-3.32). In contrast, they had a greater knowledge of the vector (OR=1.53; 95% CI: 1.00-2.35). In terms of practices, there was a greater chance of finding houses where water was stored (OR=1.69; 95% CI: 1.11-2.57) and regarding the entomological aspects, more houses with adult mosquitoes were found (OR=2.13 95% CI: 1.29-3.50). Conclusions: We found important differences among the neighborhoods regarding knowledge, practices, and the presence of adult stages of the vector, which helps to explain the epidemiology of dengue in these sites.

Adipositas cordis is a rare cardiomyopathy characterized by diffuse fatty infiltration of the ventricular myocardium or interventricular septum. This occurs without myocardial cell destruction, unlike arrhythmogenic right ventricular cardiomyopathy. A 40-year-old obese woman was found to have a II/VI systolic murmur that worsened with standing. A transthoracic echocardiogram showed interventricular septal hypertrophy with a preserved left ventricular ejection fraction. Cardiac magnetic resonance imaging revealed a fatty mass in the interventricular septum. An endomyocardial biopsy revealed structurally normal myocytes with diffuse adipose cell infiltration and no evidence of malignant cells. Left and right cardiac catheterizations and stress echocardiography showed no abnormalities. This case shows the importance of considering a broad differential when approaching rare diseases. It also demonstrates the utility of noninvasive imaging and its impact on clinical decision making.
