[Calcifying tendinosis of the pectoralis major muscle with intraosseous migration]. / Tendinosis calcificante del pectoral mayor con migración intraósea.

Calcifying tendinosis is characterized by macroscopic deposits of hydroxyapatite within the tendon. Most cases involve the tendons of the rotator cuff, fundamentally the supraspinous tendon, and less frequently other tendons in practically any location. Cortical erosion with intraosseous migration of calcium deposits is rare. An atypical location combined with bone involvement can often lead to confusion with other processes like an infection or malignant tumor resulting in unnecessary biopsies or interventions. We present the case of a man who presented with pain and loss of function of the shoulder. Plain-film X-rays showed an erosion of the anteromedial cortex of the proximal diaphysis of the humerus with extra- and intra-osseous calcifications that made us suspect an infectious or malignant process. The findings at computed tomography, together with the clinical and radiological course, were key in enabling us to recognize this atypical presentation of calcifying tendinosis of the pectoralis major muscle.

Efficacy and safety of Yttrium-90 radioembolization in the treatment of neuroendocrine liver metastases. Long-term monitoring and impact on survival. / Eficacia y seguridad de la radioembolización con 90Y en el tratamiento de metástasis hepáticas de tumores neuroendocrinos. Seguimiento a largo plazo y repercusión en la supervivencia.

INTRODUCTION AND OBJECTIVE: Neuroendocrine tumors (NETs) debut in 75% of cases with liver metastases (LMNETs), whose therapeutic approach includes surgical resection and liver transplantation, while liver radioembolization with 90 Y-microspheres (TARE) is reserved for non-operable patients usually due to high tumor burden. We present the accumulated experience of 10 years in TARE treatment of LMNETs in order to describe the safety and the effectiveness of the oncological response in terms of survival, as well as to detect the prognostic factors involved. MATERIAL AND METHODS: Of 136 TARE procedures, performed between January 2006 and December 2016, 30 LMNETs (11.1%) were retrospectively analyzed. The study variables were: Tumor response, time to liver progression, survival at 3 and 5 years, overall mortality and mortality associated with TARE. The radiological response assessment was assessed using RECIST 1.1 and mRECIST criteria. RESULTS: An average activity of 2.4 ± 1.3 GBq of 90 Y was administered. No patient presented postembolization syndrome or carcinoid syndrome. There were also no vascular complications associated with the procedure. According to RECIST 1.1 criteria at 6 months, 78.6% presented partial response and 21.4% stable disease, there was no progression or complete response (1 by mRECIST). Survival at 3 and 5 years was 73% in both cases. CONCLUSION: TARE treatment with 90 Y-microspheres in LMNETs, applied within a multidisciplinary approach, is a safe procedure, with low morbidity, capable of achieving a high rate of radiological response and achieving lasting tumor responses.

Radioembolization in liver tumours. / Radioembolización en tumores hepáticos.

The detection of malignant liver tumours is recently increasing. These lesions have frequently arterial vascularization which differs from healthy parenchyma with main portal flow making them especially susceptible to transarterial therapies. Transarterial Radioembolization (TARE) is an emerging treatment for the management of different liver tumours. Significant improvements in the procedure have been made so it is considered a safe and effective treatment. A multidisciplinary approach is necessary because of the complexity of the procedure. An optimal selection of the patients and good planning arteriography are essential to obtain benefit and reduce complication rate. Although TARE has been used mostly in hepatocellular carcinoma and liver metastases, indications are currently in expansion as the only treatment or in combination.

Outcomes of pelvic arterial embolization in the management of postpartum haemorrhage: a case series study and systematic review.

BACKGROUND: Postpartum haemorrhage (PPH) is an unpredictable obstetric emergency that requires a multidisciplinary approach. Pelvic arterial embolization (PAE) is considered as a second-line treatment, although the published results have not been reviewed systematically since 2007. OBJECTIVES: To evaluate success and complication rates of PAE to treat PPH in the study hospital between 2009 and 2015, and to perform a systematic review of the literature on the reported efficacy and safety of PAE for the management of PPH. SEARCH STRATEGY: A systematic review of articles on PAE in English or Spanish was conducted using Medline and the Cochrane Library. SELECTION CRITERIA: All published articles assessing success and complication rates of PAE in cases of PPH. The search was restricted to articles published in English or Spanish between 2000 and 2015, with at least 25 cases. DATA COLLECTION AND ANALYSIS: Obstetric variables, maternal haemodynamic state, pre-/postembolization management, technique-related variables, post-PAE evolution and complications were recorded in the case series study. Study characteristics, success rates and PAE-related complication rates were recorded in the systematic review. MAIN RESULTS: The case series included 29 patients. The majority of these patients were primiparous, with singleton term pregnancies and spontaneous labour. Caesarean section was performed in 62.1% of patients undergoing PAE for PPH. PAE was successful in 89.6% [95% confidence interval (CI) 78.3-100] of cases. Twenty studies were included in the systematic review, providing data from 1739 patients. PAE was successful in 89.4% (95% CI 87.9-90.9) of cases. The mortality rate was 0.9%, and other major complications were uncommon (1.8%). CONCLUSIONS: PAE was found to be a minimally invasive, highly successful and safe technique for the management of PPH. It should be considered in PPH refractory to initial treatment.

Radioembolización en tumores hepáticos / Radioembolization in liver tumours

La enfermedad hepática tumoral es cada vez más frecuente. Su peculiar forma de irrigación, predominantemente arterial, a diferencia del resto del hígado con flujo fundamentalmente por vía portal, hace a los tumores susceptibles de terapias intraarteriales. La TARE o «transarterial radioembolization» ha irrumpido con fuerza como tratamiento de tumores hepáticos de diferentes tipos. Significativas mejoras en el procedimiento a lo largo del tiempo han hecho de la TARE un procedimiento cada vez más seguro y eficaz. Además, su naturaleza multidisciplinar y la complejidad en su ejecución hacen de esta técnica un reto para todos los especialistas implicados. Una adecuada selección de los pacientes y una correcta planificación del tratamiento son necesarios para conseguir un beneficio óptimo, reduciendo además las complicaciones. Utilizada hasta ahora en el carcinoma hepatocelular y en las metástasis hepáticas del cáncer colorrectal, sus indicaciones están actualmente en proceso de expansión como tratamiento único o combinado con otros tratamientos

Tendinosis calcificante del pectoral mayor con migración intraósea / Calcifying tendinosis of the pectoralis major muscle with intraosseous migration

La tendinosis calcificante es una entidad caracterizada por el depósito macroscópico intratendinoso de hidroxiapatita. La mayoría de los casos afectan a los tendones del manguito rotador, fundamentalmente al supraespinoso, y con menor frecuencia a otros tendones prácticamente en cualquier localización. La erosión cortical con migración intraósea de los depósitos cálcicos es infrecuente. La localización atípica combinada con la afectación ósea hace que con frecuencia se confunda con otros procesos como una infección o un tumor maligno, lo que conduce a biopsias e intervenciones innecesarias. Presentamos el caso de un varón que consultó por dolor e impotencia funcional en el hombro. En la radiografía se observó una erosión de la cortical anteromedial de la diáfisis proximal del húmero con calcificaciones extra- e intraóseas que hicieron sospechar proceso infeccioso o maligno. Los hallazgos en la tomografía computarizada (TC), junto con la evolución clínico-radiológica, fueron claves para reconocer esta presentación atípica de tendinosis calcificante del pectoral mayor (AU)
