Necrotizing fasciitis is a serious infectious condition that may compromise the patient's life. In the present case study, a 42-year-old male patient was reported. The condition manifested as the presence of subjective fever, general malaise, myalgia, non-productive cough, dysphagia and neck pain ~1 week prior to hospital admission. Vascular dissection was considered as the initial diagnostic suspicion, and thus, angiotomography of neck vessels was performed, ruling out aortic and neck vessel dissection. Radiology indicated negativity for aortic syndrome and cervical vascular disease, but the presence of cervical-mediastinal edema, lamellar fluid between muscular and fatty planes and posterior pulmonary atelectasis, absence of pleural fluid or consolidations, and tonsillar hypertrophy without abscesses. Due to the rapid evolution of the condition, the presence of dyspnea with the need for supplemental oxygen, and the disproportion between the intensity of the pain described by the patient and the external findings observed, the presence of necrotizing fasciitis was considered. Point-of-care ultrasonography was performed, indicating a cobblestone pattern of the subcutaneous cellular tissue, with diffuse thickening of the anterior cervical fascia and increased echogenicity with soft tissue edema posterior to the fascia. Magnetic resonance imaging confirmed the inflammatory findings in the fascia and other cervical soft tissues, without exhibiting any signs of necrosis, but with the presence of abscesses in the visceral and carotid space.

Kounis syndrome (KS) is defined as an acute coronary syndrome triggered by the release of inflammatory mediators after an allergic attack. It usually occurs secondary to allergic injuries from foods, medications, and insect bites. However, there are no known reports of KS secondary to the intake of laxatives. This article reports the case of a 43-year-old woman who, after ingesting a dose of sodium phosphate monobasic/sodium phosphate dibasic, presented a maculopapular rash on the trunk and extremities. The electrocardiogram showed ST depression in V4-V5-V6 and signs of prolonged QTc; troponin I uptake was positive. Due to presumed myocardial injury and high suspicion of coronary disease, coronary angiography was requested, which showed epicardial coronary arteries, without angiographically significant stenosis, thus confirming the presence of KS secondary to the ingestion of a laxative.

La sobreocupación de los servicios de urgencias es un problema global que cada vez afecta más las instituciones de salud que atienden pacientes de mediana y alta complejidad, haciendo que estos permanezcan más tiempo en una sala de espera con la consiguiente demora en los tiempos de atención, bajo nivel de satisfacción de los usuarios, retraso en la toma de ayudas diagnósticas, retrasos al definir altas del servicio y favorecimiento de complicaciones médicas, entre otros. Para mejorar esta situación se han desarrollado estrategias como la creación de unidades de observación, unidades fast track o asignación de citas prioritarias para los pacientes que no requieren una atención urgente, de modo adicional el triaje, los exámenes point of care y la vinculación de especialistas en medicina de urgencias. Todo esto con el fin de mejorar la calidad de la atención de los pacientes, evitar que se presenten eventos adversos durante su proceso y disminuir la sobreocupación del servicio.

This article reports the case of a woman with tracheal perforation due to closed neck trauma and the presence of SARS-CoV-2. The physical examination revealed subcutaneous emphysema in zone II of the neck. The tomography revealed an anterior and proximal tracheal lesion, a 2-mm solution of continuity of the anterior infraglottic airway in the proximal third with subcutaneous emphysema and a decrease in the diameter of the airway at the level of the glottis. The PCR result for SARS-CoV-2 was positive. The medical procedure consisted of orotracheal intubation to guarantee the safety of the airway, in addition to close surveillance in the intensive care unit and constant monitoring of vital signs. In tracheal perforation due to closed neck trauma, it is recommended to evaluate the clinical parameters periodically, including the stability of respiration and subcutaneous emphysema.

The electrocardiogram (ECG) changes in patients with intraparenchymal hemorrhage (IPH) have remained largely elusive and no case reports are currently available in the scientific literature. The medical management of a patient with ST-segment elevation associated with IPH was described in the present study. The case report describes a 78-year-old male patient who presented with ST-segment elevation in V1, V2, V3 and V4 on ECG. Initially, the case was managed therapeutically as an acute myocardial infarction. Later, the patient was transferred to a higher-level hospital, where a new ECG confirmed ST-segment elevation. Simple skull tomography was also performed, which revealed a spontaneous right basal ganglion in the context of an acute cerebrovascular accident of hypertensive origin. A transthoracic ECG was ordered, which revealed an ejection fraction of 65% with type I diastolic dysfunction due to relaxation disorders and without any signs of ischemia, intracavitary masses or thrombi. In addition to the presence of nonspecific ECG findings, clinicians should consider immediate brain computed tomography to confirm intracranial hemorrhage.

Introducción. El sangrado en contexto de anticoagulación es uno de los riesgos que tienen ciertos pacientes durante determinados tratamientos, y es potencialmente mortal. Es importante conocer la farmacocinética de estas moléculas para predecir cuál será su comportamiento. Además se requiere juicio clínico en todos los casos de sangrado para determinar el manejo de acuerdo a la severidad. El objetivo de esta revisión es presentar un enfoque del paciente anticoagulado con sangrado en el servicio de urgencias. Temas tratados. Farmacocinética y farmacodinámica, generalidades, sangrado mayor y no mayor, opciones de reversión y tratamiento. Conclusión. En presencia de anticoagulantes orales directos (DOACS) se debe evaluar la gravedad del sangrado y el grado de anticoagulación, pues las estrategias de manejo se orientan dependiendo de si se trata de un sangrado mayor o menor.

Vertebral artery dissection is a common cause of stroke in young adults without predisposing risk factors for cerebrovascular disease. We describe the case of a 28-year-old patient who presented with an ischemic stroke secondary to a stab wound to the neck that affected the vertebral artery. A physical examination revealed neurological deterioration (Glasgow 8/15), a sutured neck wound, no palpable hematoma, no thrills, and no active bleeding. A computed tomography angiography revealed a left vertebral artery arteriovenous fistula with a component of a pseudoaneurysm, for which a neurointerventional consultation was carried out. Due to neurological compromise, the airway was secured, and because the case involved a posterior fossa infarction with compression of the fourth ventricle and obstructive secondary hydrocephalus, an external ventricular shunt was inserted by neurosurgery. A fistula occlusion was performed with five Axium coils and a vial of Squid 12; the vertebral artery was catheterized, and a craniotomy was performed to manage hydrocephalus with a 12-mm H2O collecting system. The patient was discharged on the tenth day after admission with sequelae of left hemiparesis (predominantly brachial) and no other deficits. There was no hemorrhagic transformation on the control computed tomography scans and no further complications.
