Tétanos: una enfermedad inmunoprevenible / Tetanus: an immunopreventable disease

Resumen El tétanos es causado por el Clostridium tetani, una bacteria ubicua que frente a condiciones de anaerobio sis puede sintetizar y liberar sus toxinas, responsables del cuadro clínico. Dado que es una bacteria que se encuentra en el suelo y en el tracto gastrointestinal de muchas especies, se trata de una enfermedad no erra dicable pero si controlable a través de la inmunización para la prevención. Las tasas de inmunización han disminuido en los últimos años, evento que se ha acentuado durante la COVID-19. Se presentan a continuación dos casos clínicos in gresados durante el año 2022. El primero es un hombre de 39 años cuya puerta de entrada fue una herida de arma de fuego conevolución favorable y el segundo caso se trata de una mujer de 83 años sin puerta de entrada clara quien falleció durante su internación en terapia intensiva. La importancia de esta presentación es mos trar la gravedad de la enfermedad, cuyavaloración es principalmente clínica y no debe escapar al algoritmo de diagnósticos diferenciales, acentuando que se debe instaurar el tratamiento de forma precoz o frente a la duda consultar con un centro especializado. Asímismo, es importante revisar las tasas de inmuni zación en nuestro país y los cambios que se presentaron durante la pandemia, teniendo en cuenta, como se ha expuesto previamente, se trata de una enfermedad in munoprevenible.

Abstract Tetanus is an infectious disease caused by a ubiqui tous bacterium Clostridium tetani, that synthesizes and releasesa potent neurotoxin under anaerobic conditions, which is responsible for the clinical manifestations. As it is found in soil contaminated with animal and human excreta, it is difficult to eradicate but it may be prevented by immunization. Immunization rate has decreased in the last years, especially during the COVID-19 pandemic. We report two cases of tetanus, attended during 2022. A 39-year-old man whose entry route was a gunshot wound and he was discharged from the intensive care unit (ICU) and a second case of an 83-year-old woman with unknown entry point, who died during her ICU stay. The cases reported highlight that it is a life-threatening disease, its diagnosis is mainly clinical and it should be in the algorithm of differential diagnoses. We emphasize about the prompt treatment administration or consulta tion to a specialized healthcare center. The importance of this presentation is to show the severity of the dis ease, whose assessment is mainly clinical and should not escape the algorithm of differential diagnoses, em phasizing that treatment should be instituted early or when in doubt consult a specialized center. In addition to this, it is important to check theimmunization rate in our country, especially during thepandemic, becauseit is a vaccine-pre ventable disease.

Neonatal Tetanus: demographics, clinical management and outcomes of A Study of 7 Cases in Afghanistan

This study aims to study the demographics, treatment and outcome of neonatal tetanus patients managed at Nangarhar Regional Hospital Afghanistan from June 2019-January 2021. Seventeen neonates were studied. All presented with fever, poor sucking and limb stiffness, with a history of unsterile delivery and uncertain maternal tetanus immunity status. Low-resource settings continue to report high mortality from neonatal tetanus, due to lack of sophisticated management modalities like neuromuscular blockade and invasive ventilation [20-23].The age group of mothers 21-25 of admitted neonates shows high frequency i.e 42.85%. Education of mother of admitted neonates was Primary education i.e 57.14%. 71.42 % (5) mothers not vaccinated. The vaccination awareness should be implemented in community by organising various awareness camp town wise. Government should implement the education mandatory and free for below poverty class and females.

Tétanos generalizado: Una amenaza persistente, reporte de tres casos y revisión de la literatura / Generalized tetanus: A persistent threat, review of the literature and report of three cases

RESUMEN INTRODUCCIÓN: El tétanos es una enfermedad inmunoprevenible, ocasionada por la bacteria Clostridium tetani, desencadenando una enfermedad caracterizada por espasmos musculares, insuficiencia respiratoria y disautonomías, potencialmente mortal. MATERIALES Y MÉTODOS: Presentamos una serie de tres pacientes que consultaron al servicio de urgencias por presentar trismus, rigidez muscular generalizada y dificultad respiratoria, requiriendo manejo en la unidad de cuidados intensivos, con relajación muscular y administración intramuscular e intratecal de inmunoglobulina antitetánica, con evolución satisfactoria en todos los casos. DISCUSIÓN: Su tratamiento está divido en dos grandes secciones; la primera parte, el control de la infección y eliminación del agente causal, con lavado y desbridamiento de heridas, administración de antibióticos y neutralización de la neurotoxina. La segunda parte del tratamiento está en el soporte vital en la unidad de cuidados intensivos, con la administración de sedación, relajación muscular, control de disautonomías y manejo de complicaciones. CONCLUSIONES: El tétanos a pesar de los avances en vacunación aún es una enfermedad presente, cuyo diagnóstico y tratamiento rápido y adecuado, permite sobrevivir a los pacientes, como en los casos aquí reportados.

ABSTRACT INTRODUCTION: Tetanus is an immuno-preventable disease, produced by the bacterium Clostridium tetani, that causes a disease characterized by muscle spasms, respiratory insufficiency and life-threatening dysautonomia. MATERIALS AND METHODS: We present a series of three patients who consulted for trismus, muscle stiffness and respiratory failure, which required intensive care management, muscle relaxation, intramuscular and intrathecal administration of tetanus immu-noglobulin, with satisfactory outcomes in all the cases. DISCUSSION: Its treatment is divided into two main sections; the first part, the control of infection and elimination of the causative agent, with washing and debridement of wounds, administration of antibiotics and neutralization of the neurotoxin. The second part is life support in the intensive care unit, with the administration of sedation, muscular relaxation and control of dysautonomia and the management of complications. CONCLUSIONS: Despite the advances in vaccination, tetanus is still a present disease, whose diagnosis and rapid and adequate treatment allows patients to survive, as in the cases reported here.

Tétanos generalizado en adulto. Reporte de caso / Adult generalized tetanus. Case report

RESUMEN Fundamento: El tétanos es una enfermedad infecciosa causada por las esporas de la bacteria Clostridium tetani que afecta el sistema nervioso. La inmunización contra esta enfermedad ha permitido reducir la morbilidad y la mortalidad en Cuba por esa causa. Los pocos casos reportados son pacientes sin previa vacunación contra el tétanos, por lo que constituye de interés para la comunidad científica el reporte de aquellos que desarrollan esa enfermedad después de haber sido vacunados. Objetivo: Describir el caso de un paciente con diagnóstico de tétanos generalizado a pesar de que ya había sido vacunado contra esa enfermedad. Presentación del caso: Paciente de 33 años, con el antecedente de haber sido vacunado contra el tétanos, al cual le diagnosticaron tétanos generalizado, por lo se decidió su ingresó en la unidad de cuidados intensivos. Clínicamente se manifestó por contracciones musculares generalizadas y rigidez, los síntomas y signos neurológicos tuvieron una duración de 4 semanas. A pesar de las complicaciones el paciente egresó con adecuada calidad de vida. Conclusiones: La presentación de este caso busca concientizar en la comunidad científica la importancia de considerar el diagnóstico de tétanos en pacientes ya vacunados, lo cual es poco frecuente y obliga a actuar con prontitud.

ABSTRACT Background: Tetanus is an infectious disease caused by the bacterium Clostridium tetani spores which affects the nervous system. In Cuba, immunization against this disease has made it possible to reduce morbidity and mortality from this cause. The few cases reported are patients without prior vaccination against tetanus, so is the interest to the scientific community the reporting of those who develop this disease after having been vaccinated. Objective: To describe a patient´s case with a generalized tetanus diagnosis despite has already been vaccinated against this disease. Case report: A 33-year-old patient, with a history of has been vaccinated against tetanus, and diagnosed with generalized tetanus, so it was decided he to be admitted to the intensive care unit. Clinically manifested by generalized muscle contractions and stiffness, the neurological symptoms and signs lasted 4 weeks. Despite the complications, the patient discharged from hospital with an adequate life quality. Conclusions: This case presentation searches for raising awareness in the scientific community about the importance of considering the diagnosis of tetanus in previous vaccinated patients, which is rare and requires quickness of action.

Tetanus in horses: an overview of 70 cases / Tétano em equinos: um panorama de 70 casos

Tetanus is characterized by high case fatality rates in horses. Comprehensive case series studies involving equine tetanus from different geographic areas enable the evaluation of prognosis, efficacy of treatment, and control measures. We retrospectively investigated some selected epidemiological data (breed, age, gender, use of the horses, history of vaccination, seasonality, presence of wound/history of surgical procedures, clinical outcomes) and main clinical aspects (clinical signs, incubation period, length of hospitalization, and period between onset signs and hospitalization) in 70 cases of equine tetanus over 1990-2015, with emphasis in the association between these data and the clinical outcomes. High mortality rate (72.9%) was observed in this study. Forty (57.1%) horses presented history of wounds or surgical procedures related with tetanus, represented mainly by lesions in the hind limbs (42.5%), front limbs (15.0%), umbilical infections (7.1%), castration (4.3%), and face wounds (4.3%). Hyperesthesia, limb spasticity, cervical stiffness, tetanic spasms, and restriction of jaw movement were the main consistent clinical signs. Besides no statistical association, all the horses with umbilical infections, wounds in face, prolonged recumbency, sweating, dysphagia/aphagia died, and together with delay between onset of first clinical signs and prompt veterinary assistance (< 5 days) were considered indicative of poor prognosis; whereas there was a significant association (p=0.001) between survival and length of hospitalization > 7 days, seemed as an evidence of good prognosis. The high mortality rate of tetanus, even in horses under specific treatment, highlight the need for early diagnosis, prompt veterinary assistance, and establishment of prophylatic measures in equine farms.(AU)

Tétano é caracterizado por elevada mortalidade em equinos. Estudos envolvendo séries de casos da doença provenientes de diferentes áreas geográficas possibilitam avaliar o prognóstico, eficácia do tratamento e ações de controle. Foram avaliados, retrospectivamente, os principais achados epidemiológicos (raça, idade, sexo, uso dos equinos, história de vacinação, sazonalidade, presença de lesões/histórico de procedimentos cirúrgicos e evolução dos casos) e aspectos clínicos (sinais clínicos, período de incubação, tempo de hospitalização e período entre início dos sinais e hospitalização) em 70 casos de tétano em equinos atendidos entre 1990 e 2015, com ênfase na associação entre os dados clínico-epidemiológicos e a evolução dos casos (mortalidade). Foi observada alta mortalidade (72,9%) nos equinos. Do total de equinos, 57,1% apresentavam lesões ou histórico de procedimentos cirúrgicos relacionados com tétano, representados principalmente por lesões em membros posteriores (42,5%), membros anteriores (15,0%), infecções umbilicais (7,1%), castração (4,3%) e lesões de face (4,3%). Hiperestesia, espasticidade dos membros, rigidez de pescoço, espasmos tetânicos e restrição aos movimentos de mandíbula foram os principais sinais clínicos observados. Apesar da ausência de significância estatística, todos os animais com presença de infecções umbilicais, lesões na face, decúbito prolongado, sudorese e disfagia/afagia evoluíram para óbito e, associado ao início dos sinais clínicos e a demora no atendimento (< 5 dias), foram considerados indicativos de prognóstico reservado. Em contraste, foi observada associação significante (p=0,001) entre a sobrevivência dos animais e o tempo de hospitalização maior que 7 dias, considerado uma indicação de bom prognóstico. A elevada mortalidade do tétano, mesmo em equinos tratados, enfatiza a necessidade do diagnóstico precoce, do rápido atendimento veterinário e adoção de medidas profiláticas nos criatórios.(AU)

Tétano canino ­ Relato de caso / Tetanus in dogs ­ Case report / Tétano canino ­ Relato de caso

O tétano refere-se a uma condição infecciosa ocasionada por toxinas do Clostridium tetani, bacilo Gram positivo e anaeróbico, o qual ao sofrer lise e morte nos tecidos do hospedeiro libera toxinas capazes de bloquear a liberação do neurotransmissor inibidor de glicina e a liberação do ácido gama-amino butírico, levando a um quadro de tetania. Os sinais clínicos da enfermidade são o trismo e opistótono, entre outros. O diagnóstico se dá por meio de histórico e sinais clínicos e o tratamento é sintomático. O presente artigo tem o objetivo de relatar um caso clínico de tétano em um macho canino da raça Pitbull, de um ano de idade. O cão foi, atendido no Hospital Veterinário da Universidade Paranaense, Umuarama, PR, com sinais clínicos neurológicos como rigidez muscular e opistótono, iniciados após ferimento no coxim plantar. Pelo histórico e sinais clínicos firmou-se o diagnóstico de tétano. Foi instituído tratamento, mas o animal teve óbito, sendo que a doença tem alta mortalidade na espécie.(AU)

Tetanus is an infectious condition caused by Clostridium tetani toxins, a Gram-positive, anaerobic bacillus, which, when undergoing lysis and death in the host tissues, releases toxins capable of blocking the release of the glycine inhibitory neurotransmitter and the release of gamma-amino butyric acid, leading to a tetanic state. The clinical signs of the disease are trismus and opisthotonus, among others. The diagnosis is made by means of history and clinical signs, with symptomatic treatment. This article aims to report a clinical case of tetanus in a one-year-old Pitbull male canine. The dog was attended at the Veterinary Hospital at Universidade Paranaense, in the city of Umuarama, Paraná, presenting neurological clinical signs such as muscular and opisthotonous rigidity, initiated after injury to the plantar cushion. The diagnosis of tetanus was confirmed by the history and clinical signs. Treatment was instituted but the animal died, since the disease present a high mortality rate in the species.(AU)

Tétanos generalizado: caso clínico y revisión del tema / Generalized tetanus: clinical case report and review of the literature

Tetanus is a severe and potentially mortal disease, which affects the Nervous System, caused by the bacteria Clostridium tetani. It's endemic in developing countries, presenting in Chile with a rate of 0,02 cases per 100.000 habitants, but the antitetanic vaccine has reduced its incidence in developed countries. We present here a case report of a patient with generalized tetanus from our hospital. The clinical presentation was characterized by generalized increased muscle tone and trismus, and the patient was hospitalized in the Intensive Care Unit. The neurologic manifestations were important for a period of 3 weeks, but then they started decreasing until the patient was discharged, without complications and being able to sit and walk with assistance. In relation to this case, we will review the actualizations in the subject of Tetanus. The recommended treatment includes support therapy, prevention of complications, antibiotics, muscle relaxants and anti-tetanospasmin immunoglobulin; all therapies that our patient received partially. The disease has a mortality that reaches the 50 percent in some series, but the ones who survive have a good prognosis and full recovery. This is why the presentation of this case is important, being an infrequent disease that must be diagnosed timely and be treated adequately.

Introducción: El tétanos es una enfermedad grave y potencialmente mortal, que afecta al sistema nervioso y causada por la bacteria Clostridium tetani. Es endémica en países en desarrollo, teniendo en Chile el año 2007 una tasa de 0,02 casos por cien mil habitantes. La vacuna con el toxoide antitetánico ha disminuido ostensiblemente su incidencia en países desarrollados. Caso clínico: Se presenta el caso clínico de un paciente de 18 años con tétanos generalizado ingresado a nuestro hospital. Clínicamente se manifestó con un aumento del tono muscular generalizado y trismo. Se hospitalizó en la Unidad de Cuidados Intensivos. Los síntomas y signos neurológicos tuvieron una máxima intensidad de aproximadamente cuatro semanas; posteriormente fueron disminuyendo sin presentar complicaciones severas. Al alta el enfermo lograba sentarse y caminar con ayuda. Discusión: A propósito de este caso se hace una revisión de la literatura y actualización de esta grave enfermedad. El tratamiento recomendado incluye terapia de soporte, prevención de complicaciones, antibioterapia, relajantes musculares e inmunoglobulina antitetánica; terapias que este paciente recibió. Si bien esta enfermedad tiene una letalidad promedio de un 50 por ciento, los pacientes que sobreviven tienen buen pronóstico y recuperación completa. Por ello, la presentación de este caso clínico es importante, sobre todo siendo una condición poco frecuente, que debe diagnosticarse con prontitud y, así, recibir el tratamiento adecuado.

Infecção por Clostridium tetani no recém-nascido: revisão sobre o tétano neonatorum / Clostridium tetani infections in newborn infants: a tetanus neonatorum review

A despeito de ser uma doença imunoprevenível, o tétano permanece ceifando vidas em diferentes regiões do planeta. Se para a doença de origem acidental a ocorrência de novos casos reflete a insuficiente imunização da população, no caso do tétano neonatorum o problema tem dupla natureza: a precária cobertura vacinal dos adultos e as dificuldades de acesso ao pré-natal de qualidade, situação agudizada pela extrema gravidade da moléstia nesta faixa etária, cuja letalidade pode chegar a 80 por cento. Deste modo, ainda que seja importante o reconhecimento precoce do tétano no recém-nato para seu pronto e adequado tratamento, o aspecto de maior relevância é, indubitavelmente, a implementação de adequadas medidas de profilaxia e controle. Com base nestas premissas, propõe-se, neste artigo, uma atualização sobre o tétano neonatorum, enfatizando-se, com mais vigor, o tratamento e a prevenção da moléstia.

Although tetanus is a preventable disease by vaccination, it continues to claim lives around the world. Whereas cases of accidental origin reflect insufficient population immunization, tetanus neonatorum reveals a double-nature fault-poor vaccination coverage of adults coupled with difficulties accessing appropriate prenatal care; this situation is aggravated by the extreme severity of tetanus in this age group in which the mortality rate can reach up to 80 percent. The early detection of tetanus in neonates is essential for immediately initiating the proper therapy. Therefore, although reaching an early diagnosis of tetanus is important, the most relevant aspect is related to the appropriate management and prophylaxis of this disease. Consequently, the aim of this article is to review neonatorum tetanus with an emphasis on its therapy and prevention.

Tétanos Infantil: Reporte de un Caso / Tetanus Child: a Case Report

El tétanos, enfermedad infecciosa aguda causada por el bacilo Clostridium Tetani, actualmente constituye una patología infrecuente en Bolivia gracias al Programa Nacional de Inmunización. Representa un problema de salud pública por su elevada tasa de letalidad que alcanza el 50%. Por lo que se considero muy útil la descripción de esta patología rara pero vigente mediante el análisis de este caso clínico presentado en el Hospital del Niño "Manuel Ascencio Villarroel". Presentamos el caso clínico, de un niño de dos años de edad con antecedente de caída a un pozo, con esquema de vacunación completo, se hospitalizo y se valoro como síndrome de casi ahogamiento y encefalopatía hipóxica - hipoxémica. En el 6° día de internación presento sintomatología compatible y se hace el diagnostico de tétanos generalizado. Se dio tratamiento con: Inmunoglobulina antitetánica, sedación, Vitamina K, Penicilina Sódica y Metronidazol.

Tetanus, acute infectious disease caused by bacillus Clostridium Tetani, is now a rare pathology in Bolivia through the National Immunization Program. It represents a public health problem because of its high fatal¡ty rate reaches 50%. As I find very useful description of this rare condition, but existing by analysis of this case report presented at the Children's Hospital "Manuel Ascencio Villarroel". We report the case of child a two year old with a history of falling into a pit, with complete vaccination, was hospitalized and is valued as a syndrome of near drowning, and hypoxic encephalopathy - hypoxemic. In the 6th day of hospitalization presented symptoms suggestive and the diagnosis of generalized tetanus. Treatment was given: tetanus immunoglobulin, sedation, vitamin K, Sodium Penicillin and Metronidazole.

Tétano em bovinos no sul do Rio Grande do Sul: estudo de 24 surtos / Tetanus in cattle in southern Brazil: study of 24 outbreaks

São descritos vinte e quatro surtos de tétano ocorridos no ano 2009 em bovinos de corte em propriedades situadas na região de influência do Laboratório Regional de Diagnóstico (LRD), sul do Rio Grande de Sul. Todos os rebanhos foram submetidos a procedimentos de vacinação e/ou aplicação de anti-helmíntico entre 8 e 25 dias antes do aparecimento dos primeiros sinais clínicos. O tempo de evolução variou de 12 horas até quatro dias. Os sinais clínicos observados foram: prolapso da terceira pálpebra, andar rígido, dificuldade de flexão dos membros e permanência em decúbito lateral com os membros estendidos e afastados do solo (paralisia espástica), pálpebras muito abertas, sialorréia, hiperexcitabilidade, orelhas eretas, trismo mandibular, acúmulo de alimento na cavidade oral e presença de espuma na boca e narinas em alguns casos. Alguns bovinos apresentavam área de necrose e edema hemorrágico circundada por exsudato purulento nos músculos onde havia sido aplicado algum medicamento. O soro sanguíneo e fragmentos de músculo com lesão de animais afetados foram coletados para posterior inoculação em camundongos. No exame histopatológico não foram evidenciadas alterações. O quadro clínico associado aos dados epidemiológicos e a ausência de lesões histológicas permitiram o diagnóstico de tétano. A infecção, provavelmente ocorreu durante o procedimento de vacinação, através injeções intramusculares utilizando agulhas contaminadas. Apesar do tétano não ser uma clostridiose importante na região fica evidenciado que surtos podem ocorrer em função de condições epidemiológicas adequadas e cuidados devem ser tomados para evitar perdas econômicas importantes como as que ocorreram no ano 2009 na região.

Twenty-four outbreaks of tetanus occurred in 2009 in beef cattle on farms located in the region of influence of the Regional Diagnostic Laboratory (LRD), southern Rio Grande de Sul, are described. All herds were submitted to vaccination and/or application of anthelmintics between 8 and 25 days before the onset of clinical signs of tetanus. Those were prolapse of the third eyelid, stiff gait, recumbency with limbs extended and off the ground (spastic paralysis), very open eyelids, salivation, hyperexcitability, erect ears, mandibular trismus, food accumulation in the oral cavity, and presence of foam in mouth and nostrils in some cases. At postmortem some animals had necrosis, edema and hemorrhage surrounded by purulent exudate in the muscles where some medicine had been applied. Blood serum and muscle fragments of affected animals were collected for subsequent inoculation into mice. No changes were evident in histological examination. The clinical and epidemiological data associated with the absence of histological lesions allowed the diagnosis of tetanus. The infection probably occurred during the vaccination procedure, by intramuscular injections using contaminated needles. Although tetanus is not an important disease in the region, outbreaks could occur depending on epidemiological conditions. Appropriate care should be taken to avoid major economic losses as those that occurred in 2009 in the region.

Tetanus epidemiology in Santa Catarina, Brazil from 1998 to 2008 / Epidemiología del tétanos en Santa Catarina, Brasil, entre 1998 y 2008

Objetive: This work describes demographic and clinical characteristics of individuals with accidental tetanus in Santa Catarina, Brazil. Materials and Methods: 291 cases of accidental tetanus reported from 1998 to 2008 were analyzed retrospectively through a cross-sectional, descriptive andcorrelated study based on percentage and numeric frequency as well as on number and incidence rate (i.r.) found in compulsory notification forms. Results: Most cases (73,54%) occurred among men residing in Vale do Itajaí (30,24%). The age group with the highest incidence was within the 35 to 49 range(32,30%). Complete immunization history was reported in seven cases (2,40%), the perforating injury being the most observed and the lower limbs the most affected ones. Among the reported cases, 87,62% were confirmed; 114 (39,17%) patients died.Conclusions: Accidental tetanus in SantaCatarina affects the population in asignificant way despite the fact that it is an immune preventable disease. The authorities and administrators must plan strategies to address changes in public policies related to immunization coverage of the susceptible population, mainly adults. Above all, it is important to warn society that the success of immunization programs depends on theapplication of three doses at set intervals, application of booster doses and compliance with the vaccination schedule.

Con base en el porcentajey frecuencia numérica, así como enla tasa de incidencia registrada según los formularios de notificación obligatoria. Resultados: La mayoría de los casos (73,54%) ocurrieron en los hombres que residen en Vale do Itajaí (30,24%). El grupo con mayor incidencia fue en el rango de edad de 35 a 49 años (32,30%). La historia completa de inmunización se informó ensiete casos (2,40%), la lesión erforantefue la más observada, las extremidadesinferiores fueron las más afectadas. Entre los casos reportados 87(62%) fueron confirmados; 114 (39,17%) pacientes murieron. Conclusiones: el tétanos accidental en Santa Catarina afecta a la población de manerasignificativa a pesar del hecho de que esuna enfermedad prevenible. Las autoridades y los administradores deben planear estrategias para generar cambios en las políticas públicas relacionadas con la cobertura deinmunización de la población susceptible, sobre todo los adultos. Es importante advertir a la sociedad que el éxito de los programas de inmunización depende de la aplicación de tres dosis a intervalos establecidos, la aplicación de las dosis de refuerzo y el cumplimiento del calendario de vacunación.

Tétano: quando a imunoprevenção falha / Tetanus: when vaccine prevention fails

O tétano é doença adquirida do sistema nervoso central pela contaminação de feridaspelo bacilo Gram positivo Clostridium tetani, presente em fezes de animais, solo, poeirae objetos enferrujados. O tétano, apesar de passível de imunoprevenção, ainda persistenos países em desenvolvimento, devido à cobertura vacinal incompleta e ao tratamentoinadequado de lesões traumáticas. Este trabalho descreve a evolução de pacienteatendido no Hospital Risoleta Tolentino Neves, com manifestações clínicas de tétano,caso em que a adequada abordagem terapêutica garantiu a cura. Alerta para a persistênciado tétano como doença grave e para a importância da observação do esquemavacinal e da correta abordagem de feridas.

Tetanus is a central nervous system disease, acquired by contamination of wounds by Clostridium tetani, a Gram positive bacillus present in animal feces, soil, dust and rusty objects. Although vaccine-preventable, the disease persists in developing countries, due to incomplete vaccine-coverage and inadequate treatment of traumatic injuries. This paper describes a case of a patient treated at Hospital Risoleta Tolentino Neves, with typi-cal clinical manifestations of tetanus, in whom the institution of an appropriate treatment contributed effectively to his healing. This case report highlights the persistence of tetanus in Brazilian context and aims to draw attention to the importance of observation of the immunization schedule and the correct approach to wound treatment.

Tétanos: Todavía un problema de salud pública / Tetanus: still a public health problem

El tétanos es una enfermedad inmunoprevenible que todavía causa estragos en las naciones que no han logrado coberturas protectoras de vacunación. Su tasa de letalidad alcanza el 50 por ciento. Es necesario que nuestro personal de salud esté familiarizado con su prevención, diagnóstico, tratamiento y rehabilitación. Esta revisión tiene como objetivo presentar una actualización de conocimientos sobre esta importante enfermedad, haciendo énfasis en el diagnóstico y el tratamiento.El tétanos es una enfermedad aguda de distribución mundial y presentación esporádica, infrecuente en países industrializados. Por su elevada tasa de letalidad aún representa un problema de salud pública, en especial en regiones con programas preventivos deficientes.

Tetanus is an immune-preventable disease which still causes ravages in nations without protective vaccination coverage. Its lethality rate is almost 50%. It is necessary that healthpersonnel are familiarized with its prevention, diagnosis, treatment and rehabilitation. Tetanus is an acute illness of worldwide distribution, sporadic occurrence and low frequency inindustrialized countries. Due to its high lethality rate it still is a public health problem, especially in regions with deficient preventive programs. This review presents up to date knowledge on different aspects of this important disease, with emphasis on its diagnosis and treatment.

Detección inmunoenzimática de la toxina de la bacteria Clostridium tetani: una alternativa a las pruebas biológicas con ratones / Immunoenzimatic detection of the Clostridium tetani bacterial toxin: an alternative to mice bioassays

Cell-free extracts from 20 strains of Clostridium tetani isolated from soil samples, were tested for tetanus toxin production using an enzyme immunoassay. All the extracts were classified as positive for the toxin presence, and eight of them showed absorbance values corresponding to tetanus toxin concentrations between 3.2 and 88 ng/ml; thus, they fell within the linear absorbance range (0.135-0.317). All dilutions of toxin used to obtain the calibration curve (0.0071 to 1.1 ng) were lethal for mice.

A Case of Maternal Tetanus in Korea

Tetanus is uncommon in Korea due to the introduction of vaccination programs and advances in public health. A case of maternal tetanus occurred on the 9 day postpartum in a 29-yr-old woman, who had not received a 10-yr-booster of tetanusdiphtheria toxoid after receiving the primary series of tetanus-toxoid-containing vaccine. There has hitherto been no reports on maternal tetanus in Korea. This case illustrates that tetanus remains a medical problem, principally among nonand underimmunized adults. The only way to fully prevent this disease is to ensure adequate immunization in all adults.

Un caso de tétanos infantil posiblemente asociado a una aguja contaminanda / Infantile case of tetanus possibly associated to contaminated needle

Clostridium tetani es el agente etiológico del tétanos. Esta bacteria es un bacilo esporulado anaerobio, habitante normal del suelo. Antes de 1970 se presentaban de 300 a 200 muertes anuales por esta causa. Luego fue prácticamente controlada y actualmente se presentan menos de 3 casos anuales y no hay tétanos neonatorum. El último caso de tétanos infantil presentado en Costa Rica, ocurrió en 1989, y debido las características relevantes que rodearon la historia de ese caso, cuyo desenlace fue fatal es que lo informamos, como un ejemplo de hechos que no debieron ocurrir. Se trató de un niño de 50 días de edad, hospitalizado por una diarrea con vómitos y manifestaciones espasmóticas, que murió 24 horas más tarde con el diagnóstico de tétanos. Su historia clínica reveló que cuando se inició la diarrea un médico particular le recetó antibióticos intramusculares. Los antibióticos fueron inyectados en su casa por el abuelo del niño. Presuminos que la puerta de entrada para las esporas de C. tetani fue la lesión de la aguja intramuscular. Este caso representa una lección sobre el manejo de agujas. También, es necesario que siempre pensemos en tétanos porque su agente etiológico es un habitante normal de nuestros suelos y la vacunación no elimina de nuestro ambiente.

Clostridium tetani is the etiological agent of tetanus. This bacterium is a spore forming anaerobic rod, that inhabit the soil. Before 1970 it causes 200 to 300 deaths per year in Costa Rica. Afterwards the disease was practically controlled and nowadays there are less than 3 cases by year and no cases in infants were observed. The last case in an infant tetanus that occurred in Costa Rica was in 1989; some relevance characteristics of its clinical story, which end was fatal, aimed this report, this is an example of facts that never would occur. He was a 50 day old child that had diarrhea and vomiting 3 days before admission, his grandfather gave him antibiotic injection at home. The child was admitted to hospital with muscular spasms and dead 24 hours later. We presume an infected needle was the entrance door for the Clostridium tetani spores. This case represents a lesson for the antiseptic management of needles. We should always keep tetanus in mind because its agent is a normal inhabitant in our soils and vaccination does not eliminate it from the environment.

Trial with clostridium tetani toxoid in the inhibition of malaria relapse

The effect of injection of one cc. Clostridium tetani toxoid, one week after a clinical cure of malaria, and repeated after three weeks, was tried on patients who had contracted malaria elsewhere in the Philippines, but who had settled in Manila ( non-endemic area.)
