Celulitis necrosante estéril en las extremidades de migrantes marinos tras travesías prolongadas / Sterile necrotizing cellulitis in boat immigrants’ limbs after long journeys across the ocean

Fundamento Las Islas Canarias reciben migrantes de origen subsahariano que llegan a la costa tras largas travesías marinas en condiciones adversas. El «pie de patera» es una entidad previamente descrita consistente en un cuadro clínico desarrollado a partir de heridas en los pies que se infectan por estar en contacto con aguas fecales estancadas en el fondo de estas embarcaciones. Describimos un nuevo cuadro clínico, hasta ahora no publicado, consistente en un edema masivo de las extremidades que asocia necrosis de la piel y del tejido celular subcutáneo, respeta el músculo y su etiología no es de origen infeccioso. Material y métodos Diseñamos un estudio descriptivo observacional entre los meses de septiembre del año 2020 y enero del año 2022, ambos incluidos, en el ámbito del hospital de tercer nivel situado en Gran Canaria. Se incluyeron un total de 86 pacientes en una base de datos donde se analizaron 39 variables cualitativas y cuantitativas. Resultados Un total de 16 pacientes desarrollaron el cuadro consistente en una celulitis necrosante estéril. Su fisiopatogenia difiere de la del pie de patera, ya que en todos los casos los cultivos resultan estériles. Conclusiones Como mecanismo responsable, postulamos una teoría inflamatoria derivada del efecto osmótico de la ingesta de agua de mar y/o la reposición agresiva de fluidos a su llegada a los centros hospitalarios donde ingresan con deshidrataciones hipernatrémicas graves. El tratamiento quirúrgico precoz consiste en evacuar el edema mediante incisiones tipo escarotomías, el cual alivia la sintomatología y previene la progresión del cuadro (AU)

Background In the past few years, the Canary Islands received immigrants from sub-Saharan countries that arrive to the coast after long boat trips in extreme adverse conditions. The named «trench foot» is a previously described infectious entity developed after feet wounds that get infected by being in contact with water, urine and excrements in these small and crowded boats. We describe a new clinical entity, not published yet, that consists in massive edema in the extremities associating necrosis of the skin and subcutaneous tissue that characteristically respects the muscle and with a non-infectious etiology. Material and methods A database including 86 patients arrived by boat («patera») from sub-Saharan countries from September 2020 to January 2022 was made and 39 qualitative and quantitative items were analyzed. The Research Unit performed an observational prospective statistical analysis. Results A total of 16 patients developed the entity described as necrotizing cellulitis. Its physiopathology completely differs from the one described in the trench foot, since all the cultures resulted sterile. Conclusions We postulate an inflammatory theory due to the osmotic effect from ingesting sea water and/or the aggressive fluid reposition when they arrive to the emergency room with severe dehydration and hypernatremia. Early surgical evacuation of the edema with escharotomies incisions alleviate the symptoms and prevents progression of the disorder (AU)

BACKGROUND: In the past few years, the Canary Islands received immigrants from sub-Saharan countries that arrive to the coast after long boat trips in extreme adverse conditions. The named «trench foot¼ is a previously described infectious entity developed after feet wounds that get infected by being in contact with water, urine and excrements in these small and crowded boats. We describe a new clinical entity, not published yet, that consists in massive edema in the extremities associating necrosis of the skin and subcutaneous tissue that characteristically respects the muscle and with a non-infectious etiology. MATERIAL AND METHODS: A database including 86 patients arrived by boat («patera¼) from sub-Saharan countries from September 2020 to January 2022 was made and 39 qualitative and quantitative items were analyzed. The Research Unit performed an observational prospective statistical analysis. RESULTS: A total of 16 patients developed the entity described as necrotizing cellulitis. Its physiopathology completely differs from the one described in the trench foot, since all the cultures resulted sterile. CONCLUSIONS: We postulate an inflammatory theory due to the osmotic effect from ingesting sea water and/or the aggressive fluid reposition when they arrive to the emergency room with severe dehydration and hypernatremia. Early surgical evacuation of the edema with escharotomies incisions alleviate the symptoms and prevents progression of the disorder.

Síndrome coronario agudo como primera manifestación de trombocitemia esencial: un reto para los cardiólogos / Acute coronary syndrome as the first manifestation of essential thrombocythaemia: A challenge for cardiologists

Presentamos el caso de un síndrome coronario agudo en un paciente de 30 años con trombocitemia esencial. Los síndromes coronarios agudos ocurren en el 9% de los casos en estos pacientes, y su manejo constituye todo un reto para el cardiólogo, en concreto, en cuanto a la elección del tratamiento antiagregante más adecuado y su duración, considerando que estos pacientes tienen por una parte un elevado riesgo trombótico y, además, un riesgo hemorrágico no despreciable

We present the case is presented of an acute coronary syndrome in a 30-year-old patient with essential thrombocythaemia. Acute coronary syndromes occur in 9% of cases in these patients, and their management constitutes a challenge for the cardiologist, specifically in terms of choosing the most appropriate antiplatelet therapy and its duration, taking into account that these patients have a high thrombotic risk, as well as a considerable haemorrhagic risk

Optical Coherence Tomography in Children With Microtropia.

PURPOSE: To assess whether optical coherence tomography (OCT) could be useful for detecting and documenting fixation in patients with microtropia. METHODS: Retinal fixation observation was performed using spectral-domain OCT on amblyopic children with microtropia. The position between the retinal fixation point and the anatomical fovea was measured, in microns, using the system software tools. Only patients with a high level of cooperation, OCT scan quality signal of 7 or better, and visual acuity of 0.70 logarithm of the minimum angle of resolution (logMAR) or worse in the amblyopic eye were included. RESULTS: A total of 25 patients were included: 15 with microtropia (study group) and 10 without tropia and with foveal fixation and stereopsis (control group). In the study group, microtropia was previously diagnosed in 67% of cases through the cover test, and was predominantly in the left eye (73%). The average visual acuity of the sound eye was 0.03 decimal and 0.18 logMAR in the amblyopic eye. The microtropia was 3.73 ± 3.34 prism diopters and eccentric fixation (387 ± 199 µm) with OCT was observed in all cases except one. Eccentricity was predominantly in the superonasal quadrant (57%). Both eyes in the control group and the contralateral eyes of the study group showed foveal fixation. CONCLUSIONS: OCT can play an important role in the diagnosis and measurement of eccentric fixation in eyes with microtropia, providing high sensitivity.
