ABSTRACT
BackgroundTetanus disease is caused by Clostridium tetani, an anaerobe bacteria found in dust and soil. Once reached human body through damaged tissues, C. tetani releases several neurotoxins which block the inhibitory function, leading to an increased muscle tone, ultimately causing respiratory failure. Severe tetanus is a life-threatening disease, especially in low-income-regions.MethodsThis is a retrospective case-series study, undertaken at two hospitals of Vigo (population area 600,000 inhabitants). Tetanus cases were identified through the discharge databases of both hospitals between the years 19952019. Epidemiological and clinical data were obtained from the patient's medical records.ResultsA total of 33 cases were identified; median age was 67 years, and most of patients were women (n=16, 55.2%). Generalized tetanus was the most common clinical course, and neck stiffness was the most frequent symptom. A total of 25 patients (86%) were admitted to the Intensive Care Unit, 21 required invasive ventilation and 2 patients died.DiscussionThe incidence of tetanus was low but most of cases were severe. Mortality was slightly higher than previously reported. Interestingly, the deceased patients were old-women, consistent with previously reported research in high-income-regions, while mortality in low-income-countries concentrates in middle-aged men. (AU)
IntroducciónEl tétanos es causado por Clostridium tetani, bacteria anaerobia, ubicada en el suelo. Este microorganismo penetra a través de heridas y libera neurotoxinas que bloquean la función inhibitoria, produciendo espasticidad y fracaso respiratorio. Es una enfermedad grave, especialmente en regiones empobrecidas.MétodosSerie de casos realizada en dos hospitales vigueses (área 600.000 habitantes). Los casos fueron identificados mediante los sistemas de codificación entre 1995-2019. Los datos asistenciales se obtuvieron de la historia clínica.ResultadosSe identificaron 33 casos, mediana de edad, 67 años, la mayoría mujeres (n = 16, 55,2%). El tétanos generalizado fue la forma clínica predominante, la rigidez cervical el síntoma más común. Un total de 25 pacientes requirieron ingreso en UCI, 21 ventilación mecánica, dos fallecieron.DiscusiónEl número de casos fue bajo, pero la mayoría graves. La mortalidad fue ligeramente superior a la informada previamente. La mortalidad se concentró en mujeres ancianas, concordante con otros países desarrollados, mientras que la mortalidad en regiones no-desarrolladas se agrupa en varones de mediana edad. (AU)

Once reached human body through damaged tissues, C. tetani releases several neurotoxins which block the inhibitory function, leading to an increased muscle tone, ultimately causing respiratory failure. Severe tetanus is a life-threatening disease, especially in low-income-regions. METHODS: This is a retrospective case-series study, undertaken at two hospitals of Vigo (population area 600,000 inhabitants). Tetanus cases were identified through the discharge databases of both hospitals between the years 1995-2019. Epidemiological and clinical data were obtained from the patient's medical records.

Se presenta el caso de una paciente de 34 años de edad, portadora de una neurofibromatosis de Von Recklinghausen tipo 1, con dolor torácico irradiado a abdomen, fiebre y sintomatología respiratoria; en la cual aparecieron como hallazgos imagenológicos, una masa tumoral que ocupaba gran parte del hemitórax derecho con derrame pleural asociado. La histología demostró la etiología neurofibromatosa del tumor con degeneración maligna, así como el desplazamiento e infiltración de estructuras vecinas (AU)

Se realiza un análisis de los pacientes ingresados en el Hospital General de Güines con el diagnóstico de infarto del miocardio en los años comprendidos entre 1972 y 1976. Se estudian distintos aspectos de las historias clínicas revisadas, tales como: total de pacientes egresados vivos y fallecidos; edad; sexo; raza; ocupación laboral; hábito de fumar; antecedentes de diabétes; empleo de anticoagulantes; localizació del infarto; resultado de la transaminasa glutamicoxalacética; enfermedades asociadas; complicaciones; y promedio de estadía. Se comparan los datos obtenidos con estudios realizados en nuestro país y en el extranjero (AU)
