Venous malformation differential diagnosis with an odontogenic abscess on a pediatric patient. Case report and review of the literature.

Venous malformations (VMs) are aberrant venous vessel angiogenesis present at birth. However, they can become apparent later in life, debuting in early childhood. This poses a clinical quest for surgeons, dentists, and pediatricians, as they might appear as a compressible mass in the head and neck region, not uncommonly mistaking them for odontogenic abscesses or other soft tissue tumors. The differential diagnosis can be challenging and imaging techniques are often needed. Ultrasounds are extremely useful initially as other diagnostic tools can be potentially harmful in the context of a VM. MRI is key as it provides accurate extension and location information, and allows to plan invasive treatment alternatives if the patient requires it. In this article, we present the case of a 6-year-old girl who was treated by mistake for an infection upon the diagnosis of an incipient odontogenic abscess instead of a venous malformation, and a literature review on VMs. Key words:Venous malformation, odontogenic abscess, differential diagnosis.

Anesthetic Management of a Patient with Madelung's Disease Presenting with a Giant Cervical Lipoma: A Case Report.

Madelung's disease is characterized by the presence of multiple symmetric and nonencapsulated facial, neck, and upper trunk lipomas. Depending on the location and size of lipomas, there may be concerns for difficult airway management and cardiovascular collapse. We present the anesthetic management case of a patient with cervical and mediastinal lipomas who underwent elective cervical lipoma resection.

Tuberculosis oral. Revisión de la literatura. A propósito de un caso / Oral tuberculosis. Review of the literature. A case report

La tuberculosis (TB) es una enfermedad granulomatosa crónica que afecta de forma primordial a los pulmones. La afectación de la cavidad oral es rara, lo que hace que sea infradiagnosticada e infratratada. Dicha afectación puede ser primaria o secundaria, siendo más común la afectación secundaria. Exponemos el caso de un varón fumador de 39 años que presenta una lesión ulcerada en mucosa yugal izquierda de 3 semanas de evolución. Se tomó biopsia con resultado de mucosa escamosa con ulceración e intensa inflamación crónica granulomatosa no necrotizante. Además, presentaba una lesión cavitada a nivel pulmonar. Escribimos este artículo con el fin de determinar la importancia de realizar un buen diagnóstico diferencial de las lesiones ulcerativas de la cavidad oral y recalcar el manejo multidisciplinar de esta patología.

Tuberculosis (TB) is a chronic granulomatous disease which affects the lungs in majority of the cases. Tuberculosis of the oral cavity may be overlooked in the differential diagnosis of oral lesions and can be misdiagnosed and managed incorrectly. Oral manifestations of TB are seen both in primary and secondary stages of the disease but are most commonly associated with secondary TB. A 39-year-old smoker man with an ulcerative oral lesion came to the emergency room. A partial incisional biopsy was performed, with the result of squamous mucosa with ulceration and intense chronic non-necrotizing granulomatous inflammation. In addition, he had a cavitated lesion in the lung. We write this article in order to determine the importance of making a good differential diagnosis of ulcerative lesions of the oral cavity and emphasize the multidisciplinary management of this pathology.

Traqueotomías en pacientes críticos durante la pandemia por COVID-19. Estudio preliminar de nuestra experiencia en el Hospital Universitario La Paz de Madrid / Tracheotomies in critical patients during the COVID-19 pandemia. Preliminary study of our experiences at La Paz University Hospital of Madrid

El brote epidémico causado por el virus SARS-CoV-2 se encuentra plenamente activo en España. Alrededor del 10-15 % de los pacientes ingresados precisan cuidados en unidades de críticos, siendo intubados de forma prolongada y precisando la realización de traqueotomías. Se realiza un estudio observacional de las traqueotomías realizadas por nuestro Servicio de Cirugía Oral y Maxilofacial a pacientes COVID-19 de unidades de cuidados intensivos realizadas entre el 17 de marzo y el 17 de abril de 2020. El estudio analiza aspectos epidemiológicos y clínicos de los pacientes, el tipo de técnica quirúrgica empleada, el tiempo quirúrgico, el tipo de cánula empleada, las complicaciones postquirúrgicas y el seguimiento clínico de los pacientes. Un total de 22 pacientes fueron sometidos a traquetomía reglada abierta. Fueron dieciocho hombres y cuatro mujeres de edades entre 40 y 77 años (64,9 años de media). En todos los casos la realización de traqueotomía fue como consecuencia del proceso pulmonar por la neumonia bilateral COVID-19. Dos pacientes presentaron un neumotórax en el postoperatorio inmediato como complicación, un paciente falleció durante la realización del procedimiento y otro tras su llegada a la Unidad de Cuidados Intensivos tras la realización de la traqueotomía. A pesar de que la traqueotomía es una técnica quirúrgica reglada, las características especiales de los pacientes COVID-19 hacen de este procedimiento una situación crítica por la inestabilidad pulmonar y la rápida desaturación del paciente. Todo ello obliga a la realización del procedimiento por facultativos con experiencia para disminuir el tiempo quirúrgico y poder enfrentarse a cualquier eventualidad

The outbreak caused by the SARS-CoV-2 virus is currently very active in Spain. Many infected people still require to be hospitalized. Around 10-15 % of hospitalized patients require intensive care, where they are intubated for a prolonged period, needing tracheotomies some weeks after the intubation. We will be conducting an observational study of the tracheotomies performed by our oral and maxillofacial Department to COVID-19 patients on intensive care units between March 17th and April 17th, 2020. This study will be analyzing the patients' epidemiological and clinical aspects, surgical technique employed, surgical time, type of cannula used, postoperative complications and the patients' clinical monitoring. A total of 22 patients underwent open elective tracheotomy. There were twenty-two males and three females aged between 40 and 77 (mean: 64,9 years-old). In all cases tracheotomy was carried out due to pulmonary process caused by COVID-19 bilateral pneumonia. Two patients presented pneumothorax in the immediate postoperatory care as a complication, one perished during the procedure and another did so after arriving to the Intensive Care Unit after the tracheotomy surgery. Even though tracheotomy is a ruled surgical technique, the special characteristics of COVID-19 patients make of this procedure a critical situation, mainly due to lung instability and quick desaturation of the patients. This requires the surgery to be carried out by experienced physicians in order to reduce operative time and to be able to react to any eventualities that may arise
