Klebsiella, a Clever Survivor Presenting As Pyogenic Liver Abscess Years After Travel.

Klebsiella pneumoniae is a known cause of pyogenic liver abscess and has an increased prevalence in Southeast Asia. We present two cases of individuals with remote travel history to southeast Asia presenting with fevers, chills, and abdominal pain secondary to pyogenic liver abscess. Neither individual had a comorbid medical condition or history of prior hepato-biliary pathology that would predispose them to bacterial translocation and abscess formation. These patients were both successfully treated with percutaneous drainage and antibiotics. We present these cases to add to the growing body of literature surrounding hyper-mucoid strains of Klebsiella pneumonia causing a pyogenic liver abscess.

A survivor woman after three years of a cardiac tamponade.

Primary pericardial mesothelioma is an extremely rare tumor, of unclear etiology, nonspecific presentation, with a delay in diagnosis, and a poor prognosis. We present the case of a woman with pericardial mesothelioma, whose main manifestation was cardiac tamponade, currently alive three years after diagnosis and undergoing chemotherapy treatment. .

Intraoperative radiotherapy in early breast cancer: observational comparison with whole breast radiotherapy. / Radioterapia intraoperatoria en cáncer de mama precoz: análisis observacional frente a radioterapia externa.

INTRODUCTION: In early breast cancer (EBC), a single dose of intraoperative radiotherapy (IORT) might be an option to standard whole breast radiotherapy (WBRT). However, there is no consensus about its use and clinical results. AIM: to analyse the morbidity and oncological outcomes of IORT as monotherapy in EBC. METHODS: A single centre observational analytic study was performed. A prospective IORT cohort (2015-17) and a retrospective WBRT cohort (2012-17) were selected following the same criteria: ≥ 45 y.o., invasive ductal carcinoma or variants, radiological tumour size ≤ 3 cm, positive oestrogenic receptors, negative HER2, cN0; exclusion criteria: lymphovascular invasion, multicentricity/multifocality, BRCA mutation and neoadjuvant therapy. Clinical, histological, surgical, oncological characteristics and complications were collected. RESULTS: A total of 425 cases were selected: 217 in IORT cohort and 208 in WBRT cohort. Average age in IORT and WBRT groups was 67±9.5 and 64.8 ± 9.9 y.o. respectively (p = 0.01). ASA 3 risk score patients were 17.7% in IORT and 24 cases in WBRT (p = 0.027). There were no differences in histological results or tumoral stage. Average follow up was 24.4 ± 8 months in IORT and 50.5 ± 18 months in WBRT (p < 0.001). No differences were detected in local recurrence, metastases or mortality. Complications that required reintervention or hospitalization were similar in both groups. A total of 3 and 14 cases developed early severe dermatitis in IORT and WBRT groups respectively (p = 0.01). CONCLUSION: IORT as monotherapy in selected patients with EBC stands for an alternative option versus WBRT. It seems especially useful in advanced-age patients with severe comorbidities. IORT associates lesser early severe dermatitis.

Fatal brain hemorrhage after Bothrops asper bite in the Catatumbo region of Colombia / [Hemorragia cerebral fatal después de una mordedura de serpiente Bothrops asper en la región del Catatumbo, Colombia].

Snake bites are a public health problem in tropical and subtropical regions of the world. They occur especially in rural workers and are an important source of disability and mortality. We present the case of a 59-year-old farmer from the Catatumbo region of Colombia who was bitten by a B. asper snake and suffered a fatal brain hemorrhage after the event. We draw attention to the severe bleeding disorder in contrast with the slight changes at the site of the bite, as well as on the importance of the early treatment of poisoning with antivenom even in the absence of significant skin manifestations.

Las mordeduras de serpientes son un problema de salud pública en regiones tropicales y subtropicales del mundo. Ocurren, especialmente, en trabajadores rurales, y son una importante fuente de discapacidad y mortalidad. Se presenta el caso de un hombre de 59 años, agricultor de la región del Catatumbo (Colombia), quien sufrió la mordedura de una serpiente Bothrops asper, la cual le produjo una hemorragia cerebral fatal. Se llama la atención sobre el grave trastorno hemorrágico en contraste con los leves cambios en el sitio de la mordedura, así como sobre la necesidad del tratamiento temprano de la intoxicación con el suero antiofídico, incluso, en ausencia de manifestaciones cutáneas significativas.

Radioterapia intraoperatoria en cáncer de mama precoz: análisis observacional frente a radioterapia externa / Intraoperative radiotherapy in early breast cancer: observational comparison with whole breast radiotherapy

INTRODUCCIÓN: Una única dosis de radioterapia intraoperatoria (IORT) en cáncer de mama precoz (EBC) puede ser una opción frente a la radioterapia externa estándar (WBRT). Sin embargo, no existe consenso sobre su uso y resultados. OBJETIVO: Analizar la morbilidad y resultados oncológicos de la IORT como monoterapia en el tratamiento del EBC. MÉTODOS: Se realiza un estudio analítico observacional unicéntrico, comparando una cohorte prospectiva IORT (2015-17) con una cohorte retrospectiva WBRT (2012-17). Los criterios de selección aplicados son: ≥ 45 años de edad, carcinoma ductal infiltrante o variantes, tamaño tumoral radiológico ≤ 3 cm, receptores estrogénicos positivos, HER2 negativo, cN0; criterios de exclusión: invasión linfovascular, multicentricidad/multifocalidad, mutaciones BRCA y tratamiento neoadyuvante. Se valoran características clínicas, tumorales, quirúrgicas, oncológicas y complicaciones. RESULTADOS: Se estudiaron 425 casos: 217 tratados con IORT y 208 con WBRT. La edad media en IORT y WBRT fue 67 ± 9,5 y 64,8 ± 9,9 años, respectivamente (p = 0,01). El riesgo ASA 3 en IORT fue 17,7%, frente a 24 casos de WBRT (p = 0,027). No hubo diferencias en resultados anatomopatológicos o estadificación. El seguimiento medio de IORT fue 24,4 ± 8 meses, frente a 50,5 ± 18 meses de WBRT (p < 0,001). No se hallaron diferencias significativas en recidiva local, metástasis o mortalidad. Las complicaciones que precisaron reintervención u hospitalización resultaron equiparables. La radiodermitis precoz grave se presentó en tres casos IORT frente a 14 casos WBRT (p = 0,01). CONCLUSIONES: La IORT como monoterapia en pacientes seleccionadas con EBC representa una opción alternativa frente a WBRT, especialmente en aquellas con edad avanzada y comorbilidades. Se asocia, además, con menos radiodermitis precoz grave
