Analysis of physical activity in psoriatic arthritis: relationship with clinical and analytical parameters and comorbidity-description of the sedentary patient.

Objective: This study aimed to relate physical activity and a sedentary lifestyle to clinical, biological, functional, and comorbid parameters in a cohort of patients with psoriatic arthritis (PsA). Methods: A cross-sectional study was conducted with 232 PsA patients. Physical activity and sedentary lifestyle were obtained using the International Physical Activity Questionnaire (IPAQ) questionnaire. The demographic, clinical, and biological variables measured were age, time since PsA diagnosis, smoking, type of treatment used, clinical form, presence of enthesitis, dactylitis (present or past), fatigue, tumor necrosis factor (TNF)-alpha, and interleukin 6 (IL-6). Activity and functionality were measured using the Disease Activity Index for Psoriatic Arthritis (DAPSA) and Health Assessment Questionnaire (HAQ) in peripheral forms, while the Ankylosing Spondylitis Disease Activity Score (ASDAS-PCR) and Bath Ankylosing Spondylitis Functional Index (BASFI) were measured in axial forms. Disease impact was assessed using the Psoriatic Arthritis Impact of Disease (PsAID) questionnaire. Alongside comorbidities, obesity, anxiety, depression [Hospital Anxiety and Depression Scale (HADS)], and sleep quality [Insomnia Severity Index (ISI)] were assessed. Results: The mean age was 54.6 (SD: 11.4) years, with 54.3% being male. A total of 25.6% of patients were sedentary. Physical activity and sedentary lifestyle were inversely correlated with fatigue, activity, functionality, and disease impact. Within comorbidities, they correlated with anxiety, depression, and insomnia. In addition, physical activity was inversely correlated with obesity. In linear regression analysis, physical activity was found to be related to body mass index (BMI) with a ß coefficient of -0.1 (p < 0.04; 95%CI: -194.1--4.5), and an R2 value of 0.11. In logistic regression analysis, a sedentary lifestyle was found to be related to pain, with an odds ratio (OR) of 1.5 (p < 0.001; 95%CI:1.1-1.8) and an R2 Nagelkerke value of 0.36. Conclusion: A quarter of the patients were sedentary. Lack of physical activity correlated with worse parameters of clinical activity, functionality, disease impact, and the presence of comorbidities.

Laparoscopic Approach for Ectopic Pregnancy in a Rudimentary Horn: Stepwise Demonstration of Surgical Technique.

OBJECTIVE: To provide a comprehensive, step-by-step presentation of the laparoscopic resolution of ectopic pregnancy within a rudimentary uterine horn. DESIGN: A detailed demonstration of the laparoscopic technique presented through narrated video footage. SETTING: Pregnancy occurring in the rudimentary horn of a unicornuate uterus represents a rare form of ectopic pregnancy [1]. This condition is associated with a high risk of uterine rupture. Early detection is crucial for effective management and prevention of potential complications [2,3]. In this manuscript, we present a case study of a patient diagnosed with ectopic pregnancy in a rudimentary horn, who underwent successful laparoscopic resection. INTERVENTIONS: Ten main steps were identified and described in detail during the laparoscopic resection: Step 1: identification of the anatomy; Step 2: uterine mobilization; Step 3: Open retroperitoneum; Step 4: Coagulation and section of left round ligament; Step 5: Bladder dissection; Step 6: Identification of vessels; Step 7: Coagulation and section of left utero-ovarian vessels; Step 8: Coagulation and section of uterine vessels; Step 9: Section of uterine septum; Step 10: Specimen removed. CONCLUSION: This publication offers a detailed and instructive account of the laparoscopic resection of ectopic pregnancy within a rudimentary uterine horn. The stepwise approach demonstrated in the accompanying video contributes to a deeper understanding of this complex surgical technique. VIDEO ABSTRACT.

Influence of comorbidities not associated with fibromyalgia on neuropathic pain in patients with psoriatic arthritis: relationship with clinical parameters.

Objective: Neuropathic pain (NP) may influence disease activity assessment in patients with psoriatic arthritis, this relationship being traditionally based on the presence of concomitant fibromyalgia. We analyzed the influence of other comorbidities on NP and the relationship between pain and various clinical parameters. Methods: A cross-sectional study was conducted in patients diagnosed with psoriatic arthritis, excluding patients with a previous diagnosis of fibromyalgia, depression, anxiety, diabetes and/or dyslipidemia under treatment. NP was identified using the painDETECT questionnaire (score > 18). Obesity and related clinical parameters, anxious and depressive symptoms, sleep quality and fatigue were assessed as comorbidities. Disease activity was measured using the clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) in peripheral involvement, the ASDAS-PCR in axial involvement, functioning and disease impact were measured using the Health Assessment Questionnaire-Disability Index and 12-item Psoriatic Arthritis Impact of Disease questionnaire, respectively. Results: Overall, 246 patients were included (136 men; 55%). The mean age was 53.4 ± 11.0 years. Forty-two patients had NP (17.1%). Patients with NP had higher leptin levels (OR: 1.03, 95% CI: 1.007-1.056; p < 0.01) and poor sleep quality (OR: 1.20, 95% CI: 1.09-1.297; p < 0.001). Patients with NP also had greater fatigue NRS (6.2 ± 2.2 vs. 2.4 ± 0.19, p < 0.001). Patients with NP had higher cDAPSA score (17.3 ± 5.4 vs. 8.9 ± 6.5, p < 0.001), poorer functioning (1.1 ± 0.5 vs. 0.4 ± 0.5, p < 0.001) and greater disease impact (6.1 ± 1.7 vs. 2.6 ± 1.9, p < 0.001). Conclusion: NP was correlated with sleep quality and serum leptin and may be associated with worse disease activity, functioning and disease impact.

SLEEP quality in patients with psoriatic arthritis and its relationship with disease activity and comorbidities: a cross-sectional study.

The assessment of psoriatic arthritis is complex and multidimensional. It is increasingly common to include the patient perspective using patient-reported outcomes. Although some research has explored sleep quality in patients with psoriatic arthritis, most studies have had small sample sizes, failed to assess sleep quality considering the inflammatory process together with the psychological well-being of patients, and have not described any use of sleep medication. Further, research to date has not provided data on the relationship of sleep quality with axial forms. In this context, the objective of this study was to assess sleep quality in patients with psoriatic arthritis and its relationship with clinical characteristics, disease activity, functioning, disease impact, fatigue and psychological status. A cross-sectional study was conducted including 247 consecutive patients with PsA recruited during 2021. Sleep quality was measured using the Pittsburgh Sleep Quality Index. We assessed correlations of Pittsburgh Sleep Quality Index score with peripheral disease activity (Disease Activity Index for PSoriatic Arthritis), axial disease activity (Ankylosing Spondylitis Disease Activity Score-C-reactive protein and Bath Ankylosing Spondylitis Disease Activity Index), functioning (Bath Ankylosing Spondylitis Functional Index and Health Assessment Questionnaire), impact (Psoriatic Arthritis Impact of Disease questionnaire), anxiety, depression (Hospital Anxiety and Depression Scale) and fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue) scores. A multiple linear regression model was constructed with PSQI as the dependent variable and as independent variables those that could influence sleep quality. Nearly two-thirds (63.15%) of patients had poor sleep quality. Poorer sleep quality was associated with being female, higher joint counts, greater peripheral and axial disease activity, fatigue, anxiety and depression, functioning and disease impact (p < 0.001). Multiple linear regression analysis found that pain (ß: 0.3; p < 0.007) and fatigue ß: - 0.1; p < 0.001 contributed 40% to the sleep quality model. Poor sleep quality was common among patients with psoriatic arthritis. Emotional factors (fatigue, anxiety) seemed more important than inflammatory factors in sleep quality.

Short-course radiotherapy for rectal cancer: real-world evidence in Argentina.

Background: Short-course radiotherapy (SCRT) of 25 Gy in five daily fractions is a recommended strategy in the neoadjuvant setting for resectable locally advanced rectal cancer (LARC), as well as in cases of metastatic disease for local control. There is scarce information regarding the use of SCRT for patients who have received nonoperative management. Objectives: To describe the characteristics of patients who received treatment with SCRT for LARC and metastatic rectal cancer, toxicity, and the approach after radiation treatment. Methods: This is a retrospective analysis of all patients who underwent SCRT for rectal cancer at the Alexander Fleming Institute from March 2014 to June 2022. Results: In total, 44 patients were treated with SCRT. The majority were male (29, 66%), with a median age of 59 years (interquartile range 46-73). Most patients had stage IV disease (26, 59.1%), followed by LARC (18, 40.9%). Most lesions were located in the middle rectum (30, 68%). The majority of LARC patients underwent SCRT followed by consolidation chemotherapy (ChT) (16/18, 89%), while most patients with metastatic disease underwent SCRT followed by consolidation ChT (14/26, 53.8%). A clinical complete response (cCR) was documented in 8/44, 18.2% of patients. Most patients with LARC and cCR were managed by a watch and wait approach (5/18, 27.7%). Local recurrence was observed in LARC cases (2/18, 11.1%). Patients who underwent SCRT following consolidation ChT were more likely to have adverse events (AEs) than those undergoing induction ChT following SCRT (11/30, 36.7% versus 3/12, 25%, p = 0.02). Conclusion: In a subgroup of patients diagnosed with LARC and treated with SCRT followed by ChT, surgical treatment could be omitted after they achieved a cCR. Local recurrence was similar to that reported in a previous study. SCRT is a reasonable option for local disease control in stage IV disease, yielding low toxicity rates. Therefore, decisions must be made by a multidisciplinary team. Prospective studies are necessary to reach further conclusions.

Characterization of Ovarian Granulosa Cell Tumors using Magnetic Resonance Imaging.

Purpose: To identify the MRI features that aid in the characterization of ovarian granulosa cell tumors. Materials and methods: 11 MR pelvis of an adult woman with pathology-proven ovarian granulosa cell tumors with surgical pathology.We evaluated the patient's age, Ca-125, size, laterality, and with MRI features such as indirect signs (i.e., thickened endometrium > 0.9 cm), morphology (cystic, solid-cystic, or solid), subacute hemorrhage, T2 signal (low or intermediate-to-high), restricted diffusion (B values: 0, 50, 1000 sec/mm3/ADC), and dynamic enhancement (intense or similar to myometrium). Also, the presence of ascites, peritoneal implants, or adenopathy. Results: The final cohort included 11 women with a surgical-pathological diagnosis of granulosa cell tumors. The median age was 52.4 years (range, 17-80). The Ca-125 level was with a median within normal limits. The median size was 9.4 cm. Most cases were unilateral (81.8%) and more frequent on the left (54.5%). MRI Analysis: 36.4% had endometrial thickening. Ovarian granulosa cell tumors were polymorphous: cystic (54.6%), mixed solid-cystic (9.1%), and solid (36.3%). Most GC had intermediate to high signal on T2 (90.9%), restricted diffusion (81.8%), intense enhancement (81.8%), and 36.4% had intraparenchymal bleeding. 9.1% had associated implants/adenopathy/ascites at diagnosis. Conclusion: The MRI features characteristic of ovarian granulosa cell tumors were the polymorphous morphology, an intense enhancement to the myometrium, restricted diffusion, and the presence of intraparenchymal hemorrhage.

Determinantes de la calidad de vida relacionada con la salud oral en adultos mayores de un centro diurno costarricense: Resultados de un estudio piloto / Oral Health-Related Quality of Life Determinants in the Elderly from a Costa Rican Day Center: Findings of a Pilot Study

Resumen: El cambio de la distribución demográfica en Costa Rica establece a las personas adultas mayores (PAM) como una prioridad de salud pública. La salud oral es un indicador multidimensional, que incluye dimensiones biológicas, sociales y psicológicas. En este campo de investigación, además de utilizar las medidas de morbi-mortalidad, se ha dado una importancia a distintos indicadores que pretenden aproximar otras dimensiones subjetivas. Dentro de estas, la calidad de vida toma cada vez más importancia. Este estudio pretende identificar los principales determinantes de la Calidad de Vida Relacionada con la Salud Oral (CVRSO) en PAM de un centro diurno del cantón de Desamparados en San José, Costa Rica. Se trata de un estudio descriptivo transversal de tipo observacional realizado entre 2018 y 2019. La CVRSO, se midió a través del instrumento GOHAI (General/Geriatric Oral Health Assesment Index). Como variables independientes se incluyeron las sociodemográficas, socioeconómicas, de morbilidad, comportamientos de salud y consumo de medicamentos. Se realizaron análisis bivariados con las pruebas no paramétricas de Wilcoxon, Kruskall-Wallis y Spearman, utilizando el paquete estadístico STATA 14. Este estudio revela que existen diferencias de promedio al comparar la CVRSO y los determinantes demográficos, socioeconómicos, de morbilidad, toma de medicamentos y comportamientos de salud. Los mayores de 80 años, las mujeres, aquellos con niveles superiores de escolaridad, de ingresos altos, sin edentulismo, con niveles bajos de xerostomía, sin enfermedades, que no toman medicamentos, que no fuman, hacen deporte, que no meriendan y que consumen moderadamente azúcares, son aquellos que reportan una mejor CVRSO comparados a sus contrapartes.

Abstract: The change in the demographic distribution of Costa Rica establishes the elderly as a public health priority. Oral health is a multidimensional indicator, which includes biological, social, and psychological dimensions. Besides using measures of morbidity and mortality, different indicators seek to approximate other subjective dimensions. There is an increasing interest in analyzing the role of quality of life on health. This study aims to identify the main determinants of Oral Health-Related Quality of Life (OHRQL) in the elderly attending a day center in the city of Desamparados (San José, Costa Rica). This is a descriptive cross-sectional study ran between 2018 and 2019. OHRQL was measured via the General / Geriatric Oral Health Assessment Index (GOHAI). As independent variables, sociodemographic, socioeconomic, morbidity, health behaviors, and drug consumption were included. Bivariate analyzes were performed using the Wilcoxon, Kruskall-Wallis, and Spearman non-parametric tests, using STATA 14. This study revealed differences in GOHAI scores according to demographic, socioeconomic, morbidity, medication, and health behaviors. Those over 80 years old, women, with higher levels of education, high income, without edentulism, with low levels of xerostomia, people without diseases, who do not take medication, who do not smoke, play sports, do not snack and who consume moderately sugars, are those that report a better OHRQL compared to their counterparts.

Extra-uterine endometrial stromal sarcoma arising from deep infiltrating endometriosis.

We present a compelling case of a 45-year-old female with a history of endometriosis and leiomyomas, who presented to her gynecologist with chronic pelvic pain complaints. Both a transvaginal ultrasound (US) and an MRI (magnetic resonance imaging) were ordered. The US demonstrated multiple uterine lesions, likely fibroids, and an endometrioma within the right ovary. The MRI of the pelvis with and without gadolinium identified a mass within the right ovary with homogenous intermediate T2-signal, restricted diffusion, and delayed enhancement relative to the myometrium. Several irregular-shaped lesions were also noted within the external myometrium, anterior pelvic wall, and the peritoneum, which were intermediate signal on T2-weighted images, restricted diffusion, and an enhancement pattern similar to the myometrium. The patient underwent a right adnexectomy. The histopathology findings were consistent with a low-grade endometrial stromal sarcoma (low grade-ESS) arising from the endometrial stroma of the right ovary. A debulking surgery confirmed the involvement of external myometrium, anterior pelvic wall, and the peritoneum secondary to a low-grade ESS without the endometrial cavity's involvement. The underlying hypothesis is that the endometriosis stroma from extra-uterine structures such as the right ovary, pelvic and anterior peritoneum, and external myometrium may have subsequently resulted in a low-grade ESS. Low-grade extra-uterine ESS without endometrial involvement is a rare entity. Based on our literature search, this is one of the few reports covering the radiological features of low-grade extra-uterine ESS arising outside the uterus with a concomitant deep infiltrating endometriosis, but without the involvement of the endometrial cavity.

Placental site trophoblastic disease.

A case study of a 38-year-old woman with a diagnosis of placental site trophoblastic tumor is presented. The patient had a 22-month history of amenorrhea since her last pregnancy, and a dilation and curettage procedure was performed after a 3.1×2.4×2.8 cm endometrial echogenic lesion was visualized on a pelvic ultrasound. When the diagnosis of placental site trophoblastic tumor was made by histopathologic and immunohistochemical analysis, complementary examinations including including pelvic magnetic resonance imaging (MRI) and a chest computed tomography (CT) were done. There was no evidence of disease outside the uterus, and a laparoscopic hysterectomy with bilateral salpingectomy was performed. After a surveillance period of 12 months, no disease recurrence was identified. Best imaging studies, treatment options, and proper surveillance for these type of tumors are discussed alongside the case study.

Alertas de cardiotoxicidad en el tratamiento con trastuzumab en cáncer de mama, 4 años de seguimiento / Cardiotoxicity Alerts during Treatment with Trastuzumab in Breast Cancer at Four-year Follow-up

RESUMEN Introducción: El tratamiento adyuvante de cáncer de mama Her2+ incluye adriamicina y trastuzumab, un anticuerpo monoclonal con efecto cardiotóxico del que no se conoce el verdadero impacto epidemiológico de toxicidad cardíaca en poblaciones no seleccionadas en la Argentina. Objetivos: Conocer el impacto cardiotóxico del tratamiento con trastuzumab en adyuvancia en cáncer de mama en una población no seleccionada a más de 12 meses después de finalizado su tratamiento. Material y métodos: Sobre 888 pacientes prospectivos con cáncer de mama, 231 pacientes (38%) presentaban cáncer de mama Her2+, en tratamiento adyuvante con adriamicina + trastuzumab. Las pacientes fueron evaluadas mediante fracción de eyección ventricular izquierda, en pretratamiento, fin de adriamicina y cada 3 meses en el seguimiento. Se definió cardiotoxicidad a la caída de la fracción de eyección ventricular izquierda > 10% según el American College of Cardiology, se subanalizó con algoritmos del estudio B-31 y MD ANDERSON. Resultados: Presentaron caída de la fracción de eyección ventricular izquierda > 10%: 150/231 pacientes (65%) respecto del basal con un seguimiento medio de 48 ± 12 meses. En el análisis por grupo, las pacientes incluidas en el B-31 vs. MD Anderson vs. el American College of Cardiology presentaron mayor pérdida porcentual de la fracción de eyección ventricular izquierda durante el tratamiento: 20% vs. 20% vs. 16% con p < 0,04, finalizaron el seguimiento con fracción de eyección ventricular izquierda < 50%: 42% vs.41% vs. 33% con p = 0,01, respectivamente. Conclusiones: En la población con trastuzumab bajo control cardioncológico, se observó luego de un seguimiento medio de 48 ± 12 meses: 1 - Caída significativa de la fracción de eyección ventricular izquierda en más del 60% de la población. 2 - Las distintas guías muestran diferentes riesgos cardiotóxicos lo que requiere un monitoreo continuo cardioncológico.

ABSTRACT Background: Adjuvant treatment of HER2+ breast cancer includes adriamycin and trastuzumab, a monoclonal antibody that produces cardiotoxicity. The actual epidemiologic impact of trastuzumab-related cardiotoxicity in unselected populations in Argentina remains unknown. Objectives: The aim of this study was to evaluate the impact of trastuzumab-related cardiotoxicity during adjuvant treatment for breast cancer in an unselected population after >12 months of completing therapy. Methods: Among 888 patients prospectively evaluated for breast cancer, 231 (38%) were HER2+ and received adjuvant therapy with adriamycin and trastuzumab. Left ventricular ejection fraction was evaluated before treatment, after completing adriamycin and then every 3 months during follow-up. Cardiotoxicity was defined as a decline in left ventricular ejection fraction >10%, according to the definition of the American College of Cardiology and was compared with the definitions of the B-31 trial and the MD Anderson Cancer Center. Results: A decline in left ventricular ejection fraction >10% from baseline values occurred in 65% (n=150) of the patients during a mean follow-up of 48±12 months. In the per group analysis, patients included in the B-31and MD Anderson Cancer Center vs. the American College of Cardiology definitions presented greater percent fall in left ventricular ejection fraction during treatment: 20% vs. 20% vs. 16%, respectively (p<0.04) and ended treatment with left ventricular ejection fraction <50% in 42% vs. 41% vs. 33% of cases, respectively (p=0.01). Conclusions: In the population treated with trastuzumab under cardio-oncology surveillance during 48±12 months: 1 - Left ventricular ejection fraction was significantly decreased in more than 60% of patients. 2 - Different guidelines show different cardiotoxicity risks which demands continuous cardio-oncological monitoring.

Síndrome de Cushing iatrogénico por corticoides inhalados en paciente VIH / Cushing syndrome in a HIV patient using inhaled steroids: report of one case

We report a 41-year-old man with HIV and a chronic obstructive pulmonary disease, treated for seven months with Fluticasone/Salmeterol and antiretroviral therapy (Lamivudine, Tenofovir, Atazanavir and Ritonavir). While using these medications, the patients developed a Cushing syndrome in a period of five months. After performing laboratory and imaging tests, it was concluded that the most probable cause of the syndrome was the interaction of inhaled steroids with Ritonavir. After discontinuing these medications the syndrome reverted in a period of 8 months.

Evaluation of growth in diesel fuel and surfactants production ability by bacteria isolated from fuels in Costa Rica / Evaluación de crecimiento en combustible diesel y capacidad de producción de surfactantes en bacterias aisladas de combustibles en Costa Rica

A total of 149 bacterial strains previously isolated from fuels stored in Costa Rica were selected in terms of their ability to grow aerobically in diesel and produce bioemulsifier active compounds. The diesel growth was evaluated by a redox-indicator based test, and surfactant production was estimated indirectly by both the emulsification index determination (E24) and hemolytic activity. Twenty-six strains (16.8%) were considered as capable of growing in diesel, while surfactant production was detected in 22 (14.8%), estimated according to E24. Seven strains showed high production of biosurfactants (E24 ≥ 50%), headed by Pseudomonas aeruginosa 148D-O, P. aeruginosa 87R-B and Bacillus pumilus 133S-B. No significant correlation was observed between hemolytic patterns and growth outcomes in diesel or E24. Surfactant producing strains should be studied further to assess its potential applications.

Un total de 149 cepas bacterianas previamente aisladas de combustibles almacenados en Costa Rica fueron seleccionadas en términos de sus habilidades para crecer aeróbicamente en diesel y producir compuestos con actividad bioemulsificante. El crecimiento en diesel fue evaluado por medio de un test basado en un indicador redox, y la producción de surfactantes fue estimada indirectamente con las determinaciones del índice de emulsificación (E24) y la actividad hemolítica. Veintiseis cepas (16,8%) fueron consideradas como capaces de crecer en diesel, mientras que la producción de surfactantes fue detectada en 22 (14,8%), estimado de acuerdo con el E24. Siete cepas mostraron alta producción de biosurfactantes (E24 ≥ 50%), encabezadas por Pseudomonas aeruginosa 148D-O, P. aeruginosa 87R-B y Bacillus pumilus 133S-B. No se observó correlación significativa entre los patrones de hemólisis y los resultados de crecimiento en diesel o E24. Las cepas productoras de surfactantes deben ser estudiadas más a fondo para evaluar sus potenciales aplicaciones.

Avances en el diagnóstico precoz y tratamiento del cáncer de ano / Advances in the early diagnosis and treatment of anal cancer

El cáncer de ano es una neoplasia poco frecuente en la población general, pero, en poblaciones de riesgo, su incidencia sobrepasa al cáncer de cérvix en la era pre-Papanicolaou. El virus del HPV está directamente relacionado con su desarrollo, sumado a factores predisponentes, como infección por HIV, costumbres sexuales, hábito de fumar, inmunosupresión e infección genital por el primer virus. La detección precoz sólo está indicada a determinados grupos, con las muestras de citología anal y anoscopía de alta resolución como principales herramientas para diagnosticar y tratar las lesiones preneoplásicas. Un correcto diagnóstico histológico e imagenológico es indispensable para un tratamiento óptimo cuando estas lesiones progresan a cáncer, con nuevas técnicas radio-quimioterápicas, reservando cirugías de rescate con reconstrucciones perineales en caso de recaídas locales, que se diagnostican con un seguimiento adecuado.

Anal cancer is an unusual neoplasia in the general population, but, in at-risk populations, its incidence surpasses the cervical cancer in the pre-Papanicolaou test era. The HPV virus is directly related to its development, in addition to other predisposing factors such as infection caused by HIV, sexual behavior, smoking habit, immunosuppression and genital infection caused by the first virus. The early detection is only indicated to certain groups, with the anal cytology samples and the high resolution anoscopy being the main tools to diagnose and treat preneoplastic lesions. When these lesions develop into cancer, a proper histological and imaging diagnosis is essential to carry out an ideal treatment with new radiation therapy techniques, reserving salvage surgeries with perineal reconstructions for the cases of local reIapse, which are diagnosed with an appropriate monitoring.

Efecto de las drogas antracíclicas sobre la función ventricular izquierda en pacientes con cáncer de mama / Effect of antracíclicas drugs on the left ventricular function in patients with breast cancer

Objetivo: analizar la fracción de eyección ventricular izquierda (FEVI) en pacientes (ptes.) mujeres tratadas por cáncer de mama (Ca.ma) con drogas antracíclicas y con criterio de curación bajo seguimiento clínico oncológico y comparar la FEVI con un grupo de ptes. testigo con diagnóstico de Ca.ma que no hayan comenzado su tratamiento quimioterápico con antraciclinas. Materiales y métodos: sobre un total de 160 ptes. mujeres con Ca.ma se evaluó la FEVI por método de Simpson´s por ecocardiografia (utilizando un ecógrafó digital GE vivid five), de las cuales 92 ptes. presentaron criterio de curación y tratamiento previo con antraciclinas denominado grupo tratamiento (grupo T-1). Se comparó su función ventricular por el mismo método con mujeres con diagnóstico de Ca.ma antes del tratamiento adyuvante con antraciclinas como grupo contro denominado grupo tratamiento (grupo T-2). Los resultados fueron expresados en medias y medianas según correspondan y el análisis estadístico para medias de Kruskal-Wallis y Chi-cuadrado. Resultados: número de ptes.: grupo T-1 92p, grupo T-2 68p. No se encontraron diferencias significativas en la edad entre los grupos T-1: 50± 10,7 años, T-2: 53±10 años ni en la cantidad de factores de riesgo coronarios mayores grupo T-1: 2,3% y grupo T-2: 2,1%. El tiempo de exposición a la droga en el seguimiento antes de ser evaluadas las ptes. en el grupo T-1 fue de 37 (±31) meses. La FEVI presentó una diferencia significativa entre ambos grupo T-1: 57,8% (±9,1) y grupo T-2: 65,6% (±6,7) con valor de p<0,00005. La dosis media acumulada de antraciclinas en el grupo T-1 fue de 449,6 (±108) mg/m2. Conclusiones: el tratamiento con drogas antracíclicas en esta población de bajo riesgo de enfermedad cardiovascular demostró predisponer al deterioro de la FEVI la cual demuestra que la función ventriclar debe ser evaluada en forma rutinaria en todo pte. expuesto a este tipo de droga con beneficio demostrado en mayor tasa de curación del...
