Paracoccidioidomicosis crónica multifocal con compromiso perioral y laríngeo en un paciente inmunocompetente: reporte de un caso / Chronic multifocal paracoccidioidomycosis with perioral and laryngeal involvement in an immunocompetent patient: case report

Introducción: la paracoccidioidomicosis es una micosis endémica en áreas tropicales de Suramérica y Centroamérica. 50 % de los pacientes tiene afectación de las membranas mucosas, y la mucosa laríngea se afecta en 22 %-43 % de los casos. Caso clínico: se presenta un caso ilustrativo de un paciente con paracoccidioidomicosis y afectación de la mucosa oral y laríngea con curso clínico sugestivo de tuberculosis diseminada. Discusión: el compromiso mucoso se presenta en 50 % pacientes con paracoccidioidomicosis, mientras que la afectación laríngea se da en 22 %-43 % de los pacientes. En la mayoría de los casos, las lesiones laríngeas se observan como masas granulomatosas con una superficie hemorrágica y se asocian con disfonía, por lo que son difíciles de diferenciar de una tuberculosis laríngea. Conclusión: la afectación laríngea en pacientes con paracoccidioidomicosis es frecuente y tiene curso clínico similar al de la tuberculosis, e implica un reto diagnóstico.

Introduction: Paracoccidioidomycosis is a mycosis endemic in tropical areas of South America and Central America. 50% of patients have mucous membrane in-volvement and the laryngeal mucosa is affected in 22-43% of cases. Case report: We present an illustrative case of a patient with Paracoccidioidomycosis with in-volvement of the oral and laryngeal mucosa with a clinical course suggestive of disseminated tuberculosis. Discussion: Mucosal involvement occurs in half of the patients with Paracoccidioidomycosis, while laryngeal involvement occurs in 22-43% of patients. In most cases, laryngeal lesions are observed as granulomatous masses with a hemorrhagic surface and are associated with dysphonia, making them difficult to differentiate from laryngeal tuberculosis. Conclusion: Laryngeal invol-vement in patients with Paracoccidioidomycosis is frequent and has a clinical course similar to that of tuberculosis, implying a diagnostic challenge.

Método JaPer. Una nueva estrategia para mejorar la capacidad inspiratoria. Ensayo Clínico Aleatorizado / JaPer Method. A new strategy to improve inspiratory capacity. Randomized clinical trial

Introducción: las enfermedades pulmonares pueden generar hospitalizaciones, estancias prolongadas, complicaciones e inclusive la muerte. Estas enfermedades repercuten negativamente en la capacidad inspiratoria y en la calidad de vida. Por lo tanto, el presente artículo pretende analizar los efectos del Método JaPer sobre la capacidad inspiratoria de los pacientes hospitalizados. Material y métodos: ensayo clínico aleatorizado inicialmente con 653 pacientes hospitalizados que pasó a 587 distribuidos en 2 grupos (Grupo experimental-GE: Método JaPer vs Grupo control-GC: uso convencional de inspirómetro volumétrico). Se determinó la capacidad inspiratoria máxima, caminata de los 6 minutos, antropometría y un cuestionario creado por los autores. Se aplicó un programa de entrenamiento de 2 semanas de 3 sesiones por día. Al GE se le aplicó el Método Japer con protocolo estandarizado para hacer ejercicios entre el 50 y el 80 % de la capacidad inspiratoria máxima del paciente y a los pacientes del GC se les realizó incentivo inspiratorio a inspiración máxima. Resultados: 587 pacientes (F:300 vs M:287) con edad promedio de 53.61±14.24 años, entre los cuales el 9.88 % tenía bajo peso, 17.89 % peso normal y el 27.26 % y 44.97 % sobrepeso y obesidad, respectivamente. Todos los participantes realizaron una caminata de 6 minutos para determinar los metros recorridos (GE: 387.70±47.59 vs GC: 371.30±49.10), velocidad (GE: 64.62±7.93 vs GC: 61.88±8.18) y el Vo2 estimado (GE: 9.96±0.79 vs GC: 9.69±0.82). Todas las variables y la capacidad inspiratoria máxima (GE: 1708.54±707.84 vs GC: 1448.83±692.79) determinaron pre y post entrenamiento. Conclusiones: el Método JaPer obtuvó mejores resultados en todas las variables evaluadas con diferencia significativa (p= <0.05) frente al grupo control, resaltando que la capacidad inspiratoria máxima aumentó en ambos grupos (GE:44 % vs GC:28 %; p= <0.05).

Introduction: Pulmonary diseases can generate hospitalizations, prolonged stays, complications and even death. These diseases have a negative impact on inspiratory capacity and quality of life. Therefore, this paper tries to analyze the effects of the JaPer method on the inspiratory capacity of hospitalized patients. Materials and methods: Randomized clinical trial initially with 653 patients, which went on to 587 hospitalized patients distributed in 2 groups (Experimental group: JaPer Method vs. Control group: Conventional use of volumetric inspirometer). Maximum inspiratory capacity, 6-minute walk, anthropometry, and a questionnaire created by the authors were determined. A 2-week training program of 3 sessions per day was applied. The GE applied the Japer Method with a standardized protocol to exercise between 50 and 80% of the patient's maximum inspiratory capacity, and the CG underwent inspiratory incentive at maximum inspiration. Results: 587 patients (F:300 vs M:287) with a mean age of 53.61±14.24 years and 9.88% of the population were underweight, 17.89% normal weight and 27.26% and 44.97% overweight and obese, respectively. All participants performed a 6-minute walk to determine meters traveled (GE: 387.70±47.59 vs CG: 371.30±49.10), speed (GE: 64.62±7.93 vs CG: 61.88±8.18) and estimated VO2 (GE: 9.96 ±0.79 vs CG: 9.69±0.82). All variables and maximal inspiratory capacity (GE: 1708.54±707.84 vs CG: 1448.83±692.79) were determined before and after training. Conclusions: The JaPer method obtained better results in all the variables evaluated with a significant difference (p=<0.05) compared to the control group. Highlighting that the maximum inspiratory capacity increased in both groups (GE:44% vs CG:28%; p=<0.05).

Long-Term Visual Outcomes in Exudative Age-Related Macular Degeneration Patients With Unanticipated Gaps in Therapy.

BACKGROUND AND OBJECTIVES: This study's objective was to describe long-term visual outcomes of patients with age-related macular degeneration (AMD) treated with intravitreal anti-vascular endothelial growth factor injections who were lost to follow-up and then resumed treatment with anti-vascular endothelial growth factor injections. MATERIALS AND METHODS: This was a retrospective cohort study of eyes with at least 7 years of follow-up following the initiation of treatment for wet AMD with and without gaps in therapy. RESULTS: The baseline mean logMAR visual acuity was 0.65 ± 0.5 (Snellen acuity 20/89) in eyes with gaps in therapy and 0.53 ± 0.3 (20/68) in eyes without gaps. In the initial 7-year follow-up period, the eyes with gaps in therapy had significantly worse visual acuity (P < .001) and this remained significant when accounting for baseline visual acuity (P < .001). CONCLUSIONS: Gaps in intravitreal injection therapy for exudative AMD were negatively associated with visual acuity. Adherence to therapy is important to address in the care of patients with exudative AMD. [Ophthalmic Surg Lasers Imaging Retina 2022;53:481-489.].

Conclusiones: El ejercicio aeróbico demostró ser un componente que mejoró resultados en la capacidad aeróbica, evidenciados en la distancia y metros recorridos post caminata de 6 minutos, así como en la calidad de vida, consumo máximo de oxígeno, fuerza y resistencia, mas no en variables ventilatorias e intercambio gaseoso.

Abstract Introduction: Comprehensive treatment for patients with interstitial lung diseases includes physical training, given the physiological effects that are generated. The objective of this study is to analyze the impact of aerobic exercise in the treatment for patients with interstitial lung diseases. Methods: Clinical trials (January 2015- June 2020) were searched in indexed databases such as Ebsco, Scopus, Medline, Medscape, PubMed Central, EMBASE, Redalyc, DOAJ and OVID. PICO, Cochrane and PEDro scale were used in each selected study. Results: Eleven clinical trials were included for this review and the quality of the studies was medium to high. All studies included the training component of aerobic exercise combined with other strategies such as strength development, endurance, flexibility. Significant changes were demonstrated in over 50% of the studies for the aerobic capacity component, maximum oxygen consumption, cardiovascular function and quality of life. Other studies, however, did not demonstrate significant differences in lung function tests, changes in ventilatory, gas exchange or cardiovascular variables as indicated by some authors in the studies conducted. Conclusions: Aerobic exercise proved to be a component that improved results in aerobic capacity evidenced in distance and meters traveled after a 6-minute walk, as well as in quality of life, maximum oxygen consumption, strength and resistance, but not in ventilatory variables and exchange gaseous.

ABSTRACT Introduction: Lymphedema is the most common sign to appear in cancer treatment, especially breast cancer. This situation mainly affects the upper limbs, blocking the lymph nodes, generating fluid retention, affecting the quality of life. One of the alternatives to treat it is physical exercise. Materials and methods: A systematic review was carried out using databases such as EMBASE, PubMed, Medscape, MEDLINE and Google Scholar, including randomized controlled trials type studies that evaluated the effects of physical exercise on lymphedema in publications from January 2013 to June 2013, 2020. The recommendations of the Cochrane collaboration for the selection of studies for systematic reviews were taken into account, as well as the criteria of the PRISMA Declaration and the PEDro scale. Results: A total of 36 articles were included, and it was observed that in 28 studies the application of physical exercise in its different modalities generated a decrease in the circumference of lymphedema, in some cases up to 61% of the initial measurement (p <0.01) while in the remaining 8 articles it was maintained, but improving the functionality of the affected limb and adaptation to it (p <0.01). Conclusions: The application of physical exercise is an alternative to treat lymphedema which obtains positive results, improving the circumference of the affected limb, functionality, strength, sensitivity and quality of life.

Need for Additional Glaucoma Surgery and Complications Following Glaucoma Drainage Device Surgery.

PRCIS: In this longitudinal study of patients with open-angle (OAG), pseudoexfoliative (PXE), or neovascular glaucoma (NVG) receiving glaucoma drainage devices (GDD), posttube cumulative rates of reoperation, corneal graft, and visually threatening complications (VT-complications) increased beyond 5 years and were not significantly affected by glaucoma type. PURPOSE: To study the need for additional glaucoma surgery and development of complications after first GDD surgery in eyes with primary OAG, PXE, or NVG glaucoma. PATIENTS AND METHODS: There were 306 eyes with OAG (n=185), PXE (n=60), or NVG (n=61) glaucoma who received a first GDD between 1996 and 2017. Outcomes including glaucoma reoperation, corneal graft procedure, and VT-complications after GDD were measured. Kaplan-Meier analysis was used to compare cumulative rate of reaching outcomes over time after GDD placement among the 3 glaucoma groups. RESULTS: When comparing the OAG, PXE, and NVG groups, there were no significant differences in post-GDD cumulative rates of reoperation (P=0.33), corneal graft (P=0.26), or VT-complications (P=0.65) over time. For all eyes, the overall cumulative rates for each outcome measure increased beyond 5 years, and specific Kaplan-Meier rates (5-y, 10-y) included: reoperation (16%, 25%), corneal graft (6%, 12%), VT-complications (9%, 14%). When comparing specific GDDs, the Ahmed FP7 had a higher cumulative reoperation rate over time compared with the Baerveldt 350 (P=0.019). CONCLUSION: Glaucoma type did not significantly affect post-GDD cumulative rates of reoperation, corneal graft, and VT-complication among the OAG, PXE, and NVG groups. For all eyes, cumulative rates of reoperation, corneal graft, and VT-complications increased beyond 5 years. The Ahmed FP7 had a significantly higher cumulative reoperation rate compared with the Baerveldt 350 over time.

Rare presentation of growing teratoma syndrome in patient with remote history of testicular cancer resection.

Growing teratoma syndrome (GTS) is documented in literature to be a rare complication of non-seminomatous germ cell tumors that arises following chemotherapeutic treatment. Though represented through multiple case reports, the condition is rare that it evades observation and diagnosis, leading to complications secondary to metastasis and unchecked growth. GTS is identified via incidental finding on imaging (e.g. CT) or due to complications involving mass obstruction. Due to the potential severity of undiagnosed malignancy, it is important to effectively diagnose GTS in those presenting with non-specific symptoms and a history of testicular/ovarian cancer. It is also necessary to develop a method on how to monitor those considered to be at increased risk for developing such a condition. Here, we present a case of a middle-aged male who presented with complaints of a left lower quadrant abdominal mass and incidental finding of right retroperitoneal lesion, consistent with GTS.

Rate of Corneal Grafting Post-Glaucoma Drainage Device Use in Pediatric and Adult Patients.

PRCIS: Kaplan-Meier analysis was used to compare the rate of corneal grafting after glaucoma drainage device (GDD) placement in pediatric and adult patients. Adults were at an increased risk of receiving a corneal graft after device placement. PURPOSE: The goal of this study was to compare the rate of corneal graft implantation after GDD placement in pediatric and adult patients. PATIENTS: Patients receiving a GDD between January 1, 1985 and December 31, 2017 were selected from the medical records. Patients receiving their first device while <18 years of age were considered children for the extent of the study. METHODS: We compared the rate of receiving a corneal graft after GDD implantation using Kaplan-Meier analysis. Baseline patient characteristics and surgical characteristics were compared using a generalized estimating equation. RESULTS: Corneal grafting occurred in 8.6% of adults and 4.7% of children from the original cohort. The rate of receiving a corneal graft at 5, 10, and 15 years was 9.4%, 16.8%, 39.4% and 1.6%, 1.6%, 12.5% for adults and children, respectively. However, certain characteristics were different between the 2 groups. CONCLUSION: Adult patients were more likely to receive a corneal graft after GDD placement. However, pediatric and adult patients differed in the prevalence of preexisting corneal disease, glaucoma type, GDD type used, and types of previous surgeries. Elucidation of the impact of these factors on corneal graft rate requires a larger cohort size.

Long-Term Follow-up of Patients with Exudative Age-Related Macular Degeneration Treated with Intravitreal Anti-Vascular Endothelial Growth Factor Injections.

PURPOSE: To determine the long-term visual outcomes and intravitreal injection burden of patients with exudative age-related macular degeneration (AMD) treated with intravitreal anti-vascular endothelial growth factor (VEGF) injections. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients with exudative AMD treated with intravitreal anti-VEGF injections with annual office visits for at least 7 years. METHODS: Snellen visual acuity was measured at baseline and then annually until the last year of follow-up. The number of injections was recorded on an annual basis during each year of follow-up. MAIN OUTCOME MEASURES: The change in the frequency of injections over time along with the change in visual acuity each year from the baseline visit through 7 years. RESULTS: During this period, 533 eyes of 429 patients were treated for exudative AMD. Of these, 391 eyes (73%) met the inclusion criteria of annual office visits and received a mean of 5.8 ± 2.5 intravitreal injections per year. The baseline mean visual acuity was 0.6 ± 0.5 logarithm of the minimum angle of resolution (logMAR; Snellen equivalent, 20/80), and the 7-year visual acuity was 0.8 ± 0.6 logMAR (Snellen equivalent, 20/126; P < 0.0001). When compared with the 142 eyes that did not undergo an office visit for a continuous 12-month period, eyes with annual office visits showed similar baseline mean visual acuity (0.7 logMAR vs. 0.6 logMAR; P = 0.2102), but more injections per year (P < 0.0001). Of the 533 total eyes, 124 eyes (23%) maintained better than 20/40 visual acuity at 7 years. These eyes received more injections overall per year (6.5 vs. 5.5 injections per year; P = 0.0007). CONCLUSIONS: In a real-world setting, eyes that maintained consistent, long-term follow-up received significantly more intravitreal injections per year than eyes with inconsistent follow-up. Eyes with 20/40 or better vision at study conclusion received more injections per year than eyes with worse than 20/40 vision.

High-performance athletes’ attitude towards doping: Validation of the Spanish version of the Performance Enhancement Attitude Scale for Colombia / Actitud frente al dopaje de deportistas de alto rendimiento: Validación de la versión española de la Performance Enhancement Attitude Scale para Colombia

BACKGROUND: Doping is the use of substances to achieve a better performance in sports. This practice is considered to be growing worldwide. Despite regulations by the World Anti-Doping Agency, 14-39% of high-performance athletes have consumed prohibited substances at least once in their sports career. The attitudes towards this type of consumption are used as predictors of the intent of usage of prohibited substances to improve physical performance. OBJECTIVE: This study aimed to validate the Spanish Version of the Performance Enhancement Attitude Scale of high-performance athletes in the Colombian context. METHODOLOGY: A cross-sectional study was performed with a convenience sampling of 112 athletes aged 15 and older, registered in a State Sports Institute in Medellín, Colombia in 2016. The participants self-completed Petróczi and Aidman instrument, Performance Enhancement Attitude Scale, adapted into Spanish by Morente-Sánchez, et al. in 2014. The reliability of the scale was assessed using Cronbach's Internal Consistency Coefficient and an exploratory and confirmatory factor analysis (CFA) was conducted to evaluate the scale's structure. RESULTS: The scale had a reliability of 0.87 and the factor analysis confirmed the unidimensionality. Of all the athletes participating in the research, the Performance Enhancement Attitude Scale average was 35.8 of 102 points, indicating a low tendency of attitudes towards doping. CONCLUSION: The psychometric properties of the 17 items of the Performance Enhancement Attitude Scale are adequate and could be used when assessing attitudes towards doping of high-performance athletes in similar contexts. This information could be used for the purposes of developing educational strategies for doping prevention in our athletes

INTRODUCCIÓN: El dopaje es el uso de sustancias para lograr un mejor desempeño en los deportes. Esta práctica parece estar creciendo en todo el mundo. A pesar de las regulaciones de la World Anti-Doping Agency, 14-39% de los deportistas de alto rendimiento han consumido sustancias prohibidas al menos una vez durante su carrera deportiva. las actitudes hacia este tipo de consumo se emplean como predictores de la intención de uso de sustancias prohibidas para mejorar el rendimiento físico. OBJETIVO: El objetivo del estudio fue validar en deportistas de alto rendimiento en el contexto colombiano la versión española de la escala de Actitudes frente al mejoramiento del rendimiento. DISEÑO: Se realizó un estudio de corte transversal en 2016 con una muestra por conveniencia de 112 deportistas de 15 y más años inscritos en un instituto deportivo estatal en Medellín (Colombia). METODOLOGÍA: Los participantes autodiligenciaron el instrumento de Petróczi y Aidman Performance Enhancement Attitude Scale (PEAS), adaptado al español por Morente-Sánchez et al. Se evaluó la confiabilidad de la escala con el coeficiente de consistencia internal de Cronbach y se hicieron análisis factorial exploratorio y confirmatorio para evaluar la estructura de la escala. RESULTADOS: Los resultados indicaron que la escala tenía una confiabilidad de 0,87 y el análisis factorial confirmó la unidimensionalidad. En los deportistas participantes en la investigación el promedio de la PEAS fue de 35,8 de 102 puntos posibles, indicando baja tendencia de actitudes hacia el dopaje. CONCLUSIÓN: Las propiedades psicométricas de los 17 ítems de la PEAS son adecuadas, y podría ser utilizada en la evaluación de actitudes hacia el dopaje en deportistas de alto rendimiento en contextos similares. Esta información podría ser utilizada para el desarrollo de estrategias educativas para la prevención del dopaje en nuestros deportistas

TEN-YEAR FOLLOW-UP OF PATIENTS WITH EXUDATIVE AGE-RELATED MACULAR DEGENERATION TREATED WITH INTRAVITREAL ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR INJECTIONS.

PURPOSE: To identify the visual acuity outcomes of patients with age-related macular degeneration treated with intravitreal anti-vascular endothelial growth factor injections over a 10-year period. METHODS: This was a retrospective, cohort study of eyes with exudative age-related macular degeneration that received ≥2 intravitreal anti-vascular endothelial growth factor injections and had at least 10 years of follow-up after the initiation of treatment. Snellen visual acuity was recorded at baseline and then annually until the last year of follow-up. Optical coherence tomography data were collected at the time of treatment initiation and at the last examination visit. A subanalysis was performed on patients who continued to receive anti-vascular endothelial growth factor therapy using a modified treat and extend protocol versus those who discontinued treatment for longer than 1 year. RESULTS: One hundred thirty eyes of 115 patients met the inclusion criteria. The mean follow-up after treatment initiation was 11.1 ± 0.7 years. Eyes received an average of 45.1 ± 32.3 intravitreal injections in total and a mean of 5 to 7 injections per year. The baseline mean logMAR visual acuity was 0.61 ± 0.5 (Snellen acuity 20/81), and the final mean logMAR visual acuity was 0.88 ± 0.7 (20/152, P value = <0.0001). There were 40 eyes that received at least one injection every year. These eyes did not have a significant change in visual acuity between the baseline and final examinations 0.47 ± 0.4 (20/59 vs. 0.58 ± 0.5 [20/76, P = 0.28]), whereas the eyes that did not receive at least one injection every year saw a significant decline in visual acuity 0.67 ± 0.5 (20/94 vs. 1.01 ± 0.7 [20/205, P < 0.0001]). CONCLUSION: Eyes with exudative age-related macular degeneration that received intravitreal injections every year had stable visual acuity over a 10-year period. Continuous intravitreal anti-vascular endothelial growth factor therapy may stabilize visual acuity for 10 years and potentially longer.

Role of Doppler echocardiography for assessing right ventricular cardiac output in patients with atrial septal defect.

BACKGROUND: Although Doppler echocardiography is routinely used to assess left ventricle cardiac output, there are limited data about the feasibility of Doppler echocardiography for right ventricular (RV) cardiac output assessment in patients with left-to-right shunt. The purpose of the study was to determine the correlation between Doppler-derived and Fick-derived RV cardiac index (CI), and the interobserver correlation in Doppler-derived RV CI assessment. METHODS: Retrospective study of patients (age ≥18 years) with unrepaired atrial septal defect who underwent cardiac catheterization and echocardiography (within 3 days), 2004-2017. RV CI was calculated using the hydraulic orifice formula: [.785 × (right ventricle outflow tract diameter)2  × right ventricular outflow tract (RVOT) time velocity integral × heart rate]/body surface area. RESULTS: A total of 128 patients (age 52 ± 17 years; female 88 [69%]) met the inclusion criteria. There was a modest correlation between Doppler-derived and Fick-derived RV CI (r = .57, P < .001), and the mean difference between Doppler-derived and Fick-derived RV CI was -.3 (95% confidence interval of agreement, -.8 to +.9) L/min/m2 . There was also a modest correlation between Doppler-derived RV CI from observer #1 and observer #2 (r = .62, P < .001), and the mean difference between Doppler-derived RV CI from observer #1 and observer #2 was -.2 (95% confidence interval of agreement, -.9 to +.6). CONCLUSIONS: The current study demonstrated a modest correlation between Doppler-derived and Fick-derived RV cardiac output, and a modest interobserver correlation in Doppler-derived RV cardiac output assessment. Further studies are required to validate these results and to explore other potential applications such as in patients with chronic pulmonary regurgitation.

Simple renal cysts and bovine aortic arch: markers for aortic disease.

Objective: This study aimed to assess the prevalence of thoracic aortic disease (TAD) and abdominal aortic aneurysms (AAA) among patients with simple renal cyst (SRC) and bovine aortic arch (BAA). Methods: Through a retrospective search for patients who underwent both chest and abdominal CT imaging at our institution from 2012 to 2016, we identified patients with SRC and BAA and propensity score matched them to those without these features by age, gender and presence of hypertension, hyperlipidaemia, diabetes and chronic kidney disease. Results: Of a total of 35 498 patients, 6366 were found to have SRC. Compared with the matched population without SRC, individuals with SRC were significantly more likely to have TAD (10.1% vs 3.9%), ascending aortic aneurysm (8.0% vs 3.2%), descending aortic aneurysm (3.3% vs 0.9%), type A aortic dissection (0.6% vs 0.2%), type B aortic dissection (1.1% vs 0.3%) and AAA (7.9% vs 3.3%). The 920 patients identified with BAA were significantly more likely to have TAD (21.8% vs 4.5%), ascending aortic aneurysm (18.4% vs 3.2%), descending aortic aneurysm (6.5% vs 2.0%), type A aortic dissection (1.4% vs 0.4%) and type B aortic dissection (2.4% vs 0.7%) than the matched population without BAA. SRC and BAA were found to be significantly associated with the presence of TAD (OR=2.57 and 7.69, respectively) and AAA (OR=2.81 and 2.56, respectively) on multivariable analysis. Conclusions: This study establishes a substantial increased prevalence of aortic disease among patients with SRC and BAA. SRC and BAA should be considered markers for aortic aneurysm development.

Perfil clínico y epidemiológico de pacientes con enfermedad pulmonar obstructiva crónica hospitalizados en un centro de alta complejidad de la ciudad de medellín, colombia, durante el año 2015

Introducción. La enfermedad pulmonar obstructiva crónica (EPOC) es una condición que cursa con limitación del flujo aéreo espiratorio e inflamación crónica de las vías aéreas, y que representa un problema de salud pública a nivel mundial. Objetivo. Determinar el perfil clínico y epidemiológico de pacientes con EPOC en una institución hospitalaria de la ciudad de Medellín, Colombia. Metodología. Se realizó un estudio transversal, con una muestra de 50 pacientes, con diagnóstico clínico o espirométrico de enfermedad pulmonar obstructiva crónica, atendidos de forma intrahospitalaria en una institución privada en Medellín durante el año 2015. A las variables cuantitativas se les calculó el promedio, desviación estándar y valores mínimo y máximo. A las cualitativas, medidas de nivel nominal y ordinal y se les estimaron proporciones. Resultados. La edad promedio fue de 73,5±9,3 años, el 52% fueron mujeres. El promedio de tiempo de diagnóstico fue de 7,8±1,3 años. Las características clínicas más frecuentes fueron las siguientes: el 36% tenía como clasificación estadio D para la enfermedad, el 34% tenía VEF1 <30%, el 88% tenían antecedente de tabaquismo y el 52% utilizaba oxígeno en casa. Conclusiones. La mayoría de nuestra población fue clasificada como GOLD categoría D, con una limitación grave del flujo aéreo espiratorio (VEF1 < 30%) y requerimiento de uso de oxígeno domiciliario. Lo anterior indica un inadecuado control de la enfermedad, debido, probablemente, al contexto intrahospitalario de los pacientes incluidos en el estudio.

Introduction. Chronic Obstructive Pulmonary Disease (COPD) is a condition that limits the air flow and produce chronic inflammation of the airways, which represents a public health problem worldwide. Objective. To determine the clinical and epidemiological profile of patients with COPD in a hospital of the city of Medellin, Colombia. Methodology. A cross-sectional study was carried out, with a sample of 50 subjects, who had a clinical or spirometric diagnosis of Chronic Obstructive Pulmonary Disease, receiving Inpatient care in a private institution in Medellin in 2015. It was calculated on quantitative variables, the average, standard deviation and minimum and maximum values. It was estimated on qualitative variables, measures of nominal and ordinal level and proportions. Results. The average age was 73.5 ) 9,3 years, 52% were women. The average of Diagnostic time was 7.8 ) 1,3 years. The most common clinical characteristics were the following: 36% had a stage D classification for the disease, 34% had FEV1 <30%, 88% had a smoking history and 52% used oxygen at home. Conclusions. The majority of our population was classified as GOLD category D, with a severe limitation to breath (FEV1 <30%) and had to use oxygen at home. The foregoing indicates that there is an inadequate control of the disease, due to the inpatient environment of the subjects involved in the study.

Introduction: myeloproliferative disorders such as Polycythemia vera (PV) belonging to the classic Philadelphian negative group, are an area of internal medicine and hematology that requires a closer look, in order to offer a clinical, diagnostic and therapeutic approach of a broad, pertinent and updated nature. Thus it would be feasibleto offer alternatives to individuals who do not respond or do not have an indication to apply a conventional treatment. Objective: to collect the characteristic or most important clinical elements of the Polycythemia Vera and to contextualize the existing or available therapeutic options and the new alternatives in development, from different basic medical disciplines such as molecular biology and the area of immunology. Materials and methods: an exhaustive review of existing bibliographic material on Polycythemia Vera, its physiopathology, current therapeutic approach and the new medical alternatives available for its treatment, was carried out during the second semester of 2017 and the first quarter of 2018. This was made under the license of Universidad Pontificia Bolivarina database, using search engines such as PubMed, Clinical Key, SciELO and Science Direct. Conclusion: the study and understanding of the pathophysiology of Polycythemia Vera is of vital importance to reach the establishment of new therapeutic alternatives for patients who suffer it and do not respond to traditional therapies, as there is still no cure for this hematological condition and currently, its therapeutic approach is mainly focused on controlling, mitigating and preventing complications associated with it..(AU)
