Assessing the impact of the 2018 tetanus guidelines on knowledge and practices of emergency physicians in trauma patients: a national survey study.

Background: Tetanus remains a significant public health issue in China, with the approach of anti-tetanus prophylaxis in the emergency department resulting in both overuse, particularly of human tetanus immune globulin (TIG), and underuse with the tetanus vaccine. This is largely due to the absence of updated guidelines on tetanus prophylaxis before 2018. Our study aimed to evaluate the effects of the 2018 Chinese tetanus guidelines on the knowledge and practices of emergency physicians about tetanus prevention in trauma patients. Methods: From November 2019 to April 2020, we conducted a web-based survey involving 499 emergency physicians. The survey included a questionnaire covering knowledge, attitudes, and practices related to tetanus. We assessed the influence of the 2018 tetanus guidelines on the knowledge and practices of emergency physicians related to tetanus prevention for patients with trauma using multiple regression analysis. Results: The survey results showed that only 45.3% of the participants had received formal training on tetanus immunization, despite 53.3% reporting the availability of tetanus vaccines at their institutions. Physicians typically prescribed tetanus antitoxin or human TIG instead of tetanus toxoid (TT) to treat injuries, regardless of the patient's TT vaccination history. Among the respondents, those who were aware of the 2018 tetanus guidelines had higher mean scores on the general knowledge, risk knowledge, and treatment knowledge scales, with increases of 6%, 13%, and 9%, respectively, compared to those who were unaware of the guidelines. Awareness of the 2018 tetanus guidelines was associated with a high level of knowledge, as indicated by the general knowledge score, recommendation knowledge score, and total knowledge score, after adjusting for the effects of all variables on the knowledge, attitudes, and practices of the participants. A high level of education was also associated with a high level of knowledge indicated by the recommendation knowledge score and total knowledge score. Conclusions: Our study highlights a substantial gap in the attitudes, knowledge, and practices of emergency physicians in China regarding tetanus immunization. The results suggest an urgent need to promote the Chinese Expert Consensus Guidelines on tetanus to improve emergency physicians' knowledge and competence in tetanus prophylaxis. The findings underscore the importance of enhancing physicians' awareness of the latest guidelines to ensure appropriate and effective treatment for patients with tetanus-prone injuries.

Caprylate/chromatography process to produce highly purified tetanus immune globulin from human plasma.

While tetanus toxoid vaccination has reduced the incidence of tetanus in the developed world, this disease remains a substantial health problem in developing nations. Tetanus immune globulin (TIG) is used along with vaccination for prevention of infection after major or contaminated wounds if vaccination status cannot be verified or for active tetanus infection. These studies describe the characterisation of a TIG produced by a caprylate/chromatography process. The TIG potency and presence of plasma protein impurities were analysed at early/late steps in the manufacturing process by chromatography, immunoassay, coagulation and potency tests. The caprylate/chromatography process has been previously shown to effectively eliminate or inactivate potentially transmissible agents from plasma-derived products. In this study, the caprylate/chromatography process was shown to effectively concentrate TIG activity and efficiently remove pro-coagulation factors, naturally present in plasma. This TIG drug product builds on the long-term evidence of the safety and efficacy of TIG by providing a product with higher purity and low pro-coagulant protein impurities.

Return of the old guard: a case of tetanus in an unvaccinated patient.

A 78-year-old woman with no known medical history presented with severe neck pain that began 4 days prior to admission located in the paraspinal cervical region radiating to the shoulders, legs and back. She had associated stiffness of her neck and progression of pain to her jaw and throat with progression to generalised body spasms with lower extremity stiffness and weakness that limited her ability to walk. She quickly developed dysphagia and odynophagia with subsequent generalised spasms and profound hypoxic respiratory failure requiring nasotracheal intubation. The presumptive diagnosis of tetanus was made and she was given tetanus toxoid immune globulin and Tdap vaccine. She was managed in the intensive care unit and after a week of admission, required a tracheostomy and gastrostomy tube placement. She required a prolonged hospitalisation stay of 21 days before being transferred to a long-term vent facility.

A Pilot Study to Assess Safety and Feasibility of Intrathecal Immunoglobulin for the Treatment of Adults with Tetanus.

Tetanus remains a significant burden in many low- and middle-income countries. The tetanus toxin acts within the central nervous system and intrathecal antitoxin administration may be beneficial, but there are safety concerns, especially in resource-limited settings. We performed a pilot study to assess the safety and feasibility of intrathecal human tetanus immunoglobulin in five adults with tetanus before the conduct of a large randomized controlled trial. Intrathecal injection via lumbar puncture was given to all patients within a median 140 (range 100-165) minutes of intensive care unit (ICU) admission. There were no serious adverse effects associated with the procedure although three patients had probably related minor adverse events which resolved spontaneously. Median ICU length of stay was 14 (range 5-17) days. Two patients required mechanical ventilation and one developed a deep vein thrombosis. Within 240 days of hospital discharge, no patients died and all patients returned to work.

[Tetanus, an almost forgotten but serious disease]. / Tetanus ­ nästan bortglömd men allvarlig sjukdom - Äldre kvinnor är en riskgrupp, diagnosen kan vara en utmaning.

Tetanus, an almost forgotten but serious disease Tetanus is the systemic consequence of a local infection with Clostridium tetani, that produces toxin which spreads in the systemic circulation. In developed countries, it is extremely rare. Women born before 1950 are a group at risk due to lower prevalence of immunisation. This report describes a case of tetanus. The patient is a previously healthy 82-year-old woman. She presented to primary care with a complaint of stiffness in the neck and jaw. A physical exam and basic laboratory tests were normal apart from a slightly increased blood pressure. Later the same day she was admitted to the intensive care unit for suspected tetanus. During the night she deteriorated with marked stiffness in her thorax and, as a result of this, severe respiratory distress. After induction of anesthesia she was ventilated and intubated without problem. The treatment for tetanus, an antibody, was given 5 hours later after urgent delivery from the national supply. The patient was successfully weaned from the ventilator after 37 days. During intensive care she had fluctuating stiffness and autonomic instability, both commonly described in patients with tetanus.

Maternal and neonatal tetanus.

Maternal and neonatal tetanus is still a substantial but preventable cause of mortality in many developing countries. Case fatality from these diseases remains high and treatment is limited by scarcity of resources and effective drug treatments. The Maternal and Neonatal Tetanus Elimination Initiative, launched by WHO and its partners, has made substantial progress in eliminating maternal and neonatal tetanus. Sustained emphasis on improvement of vaccination coverage, birth hygiene, and surveillance, with specific approaches in high-risk areas, has meant that the incidence of the disease continues to fall. Despite this progress, an estimated 58,000 neonates and an unknown number of mothers die every year from tetanus. As of June, 2014, 24 countries are still to eliminate the disease. Maintenance of elimination needs ongoing vaccination programmes and improved public health infrastructure.

Plasma como muestra alternativa para cuantificar antitoxina tetánica / Plasma as alternatively sample to quantify tetanus antitoxin

En los bancos de sangre de Cuba se cuantifica antitoxina tetánica, a partir del suero de donantes inmunizados, para producir una gammaglobulina humana específica. Se emplea un ensayo inmunoenzimático heterogéneo de tipo indirecto, que utiliza el suero como muestra analítica. En este trabajo se evalúo el posible empleo del plasma obtenido de la plasmaféresis como muestra alternativa, para minimizar el volumen de sangre total extraído a los donantes. Se seleccionó por muestreo aleatorio simple, 100 donantes de plasma que acudieron a donar entre octubre y noviembre del 2013. Para la obtención de suero se realizó una extracción de 5 mL de sangre por punción venosa, depositada en tubo de ensayo de cristal seco. La muestra de 1,5 mL de plasma se obtuvo al final de la donación, colectada en un tubo plástico con tapa. Se realizó la comparación de la diferencia de medias de ambos grupos, utilizando el programa estadístico informático SPSS para Windows. Los valores de antitoxina tetánica en suero fueron mayores que los del plasma. La media de las diferencias entre ambos grupos resultó estadísticamente significativa (p=0,00). No se recomienda usar el plasma que se obtiene de la plasmaféresis como muestra analítica para este ensayo(AU)

Tetanus antitoxin is quantified in Cuba at blood banks, from the serum of immunized donors, to produce a specific human gamma globulin. A heterogeneous indirect immunoenzymatic assay is used, using the serum as analytical sample. The possible use of plasma obtained from plasmapheresis as alternative sample was evaluated in this research, to minimize the volume of total blood extracted to the donors. One hundred plasma donors who came to donate between October and November 2013 were selected by simple random sampling. Serum sample was obtained for extraction of 5 mL of blood, deposited in dry glass tube. While the other sample took 1.5 mL of plasma in a plastic tube with cover, at the end of the donation directly of the unit of plasma collected. Comparison of the difference between the means of both groups was done using SPSS for Windows. It was found that the values obtained in serum were bigger than those obtained in plasma. Difference between the means of both groups was statistically significant (p 0.00). It is not advisable to use the obtained plasma of the plasmapheresis as analytic sample in this assay(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.

Fatal tetanus complicating an untreated mild open head injury: a case-illustrated review of cephalic tetanus.

BACKGROUND: Tetanus is now a rare disease in the Western world, but not so in developing countries. Cephalic tetanus, unlike some other local forms of the disease, is likely to be fatal. METHODS: We describe the clinical presentation of a case of fatal cephalic tetanus complicating an unattended open non-severe head injury with a review of the literature on the disease. RESULTS: Few cases of cephalic tetanus complicating head injury are found in the world literature, and many were diagnosed late. Cephalic tetanus from open or compound depressed skull fracture is even more rare. Our patient was a young male with an uncertain tetanus immunization history who sustained mild head injury (scalp laceration) and an unattended open depressed skull fracture in a motorcycle crash. He developed cephalic tetanus seven days later, presented late to our service, and died while being prepared for surgical debridement of his cranial wounds. At the immediate post-trauma medical contact, in an across-the-street "clinic," he had received suboptimal care for his head wound and inadequate tetanus prophylaxis. CONCLUSION: Cephalic tetanus is a rare form of the disease. Although it is preventable easily by well-established medical and surgical treatment paradigms, it continues to catch many clinicians disastrously unaware.

A report of two pediatric tetanus cases.

Tetanus is still a difficult-to-treat disease with high morbidity and mortality. Although it most commonly occurs in non-immunized children, it can also be seen in partially immunized or immunized children. We report herein two pediatric cases of generalized tetanus. Case 1 presented with signs of acute abdomen, while Case 2 presented with the typical clinical findings of tetanus. In this report, we highlight the importance of obtaining a history of the vaccination status of pediatric patients as an essential part of the evaluation. Furthermore, the differential diagnosis of non-immunized children with abdominal rigidity should include generalized tetanus.

Generalised tetanus in a 2-week-old foal: use of physiotherapy to aid recovery.

A 2-week-old Estonian Draft foal presented with signs of severe generalised tetanus, recumbency and inability to drink. The suspected source of infection was the umbilicus. Medical treatment was administered, including tetanus antitoxin, antimicrobial therapy and phenobarbital to control tetanic spasms. In addition, an intensive physiotherapy program was carried out during the recovery period. Techniques designed for syndromes involving upper motor neuron spasticity in humans were applied. Exercises aimed at weight-bearing and mobility were executed with the help of a walking-frame. The foal made a complete recovery. To our knowledge, this is the first report of the use of physiotherapy in the treatment of tetanus in horses.

Intrathecal anti-tetanus human immunoglobulin in the treatment of neonatal tetanus.

OBJECTIVE: To determine the outcome of tetanus in neonates treated with intrathecal tetanus immunoglobulin in terms of mortality and hospital stay. STUDY DESIGN: Experimental study. PLACE AND DURATION OF STUDY: Paediatric Unit I, Bahawal Victoria Hospital, Bahawalpur, from April 2004 to December 2007. METHODOLOGY: Seventy neonates with diagnosis of neonatal tetanus were included in the study. The neonates with fits due to causes other than tetanus were excluded. Thirty five patients received intrathecal immunoglobulin in addition to standard treatment (group A) while, the other 35 patients received only standard treatment (group B). The mortality and duration of hospital stay in 2 groups were recorded. RESULTS: In group A, mean duration of hospital stay was 10 days while, in group B it was 13 days (p < 0.001). One patient from group A and 8 patients from group B expired (p = 0.026). The occurrence of refractory fits, repeated apnoeic episodes and high grade fever did not show any statistically significant difference in the 2 groups. CONCLUSION: Intrathecal anti-tetanus immunoglobulin in addition to the standard improved the outcome of neonatal tetanus in terms of mortality and hospital stay.
