Implementing healthcare professionals' training during COVID-19: a pre and post-test design for simulation training.

BACKGROUND: Coronavirus disease-19 (COVID-19) has imposed a new reality that presents several challenges for healthcare professionals. The main challenge has been the lack of proper training in relation to an unknown disease. OBJECTIVE: To investigate healthcare professionals' acquisition of knowledge of a new airway management protocol for COVID-19 through their participation in simulation training. DESIGN AND SETTING: Pre and post-test study with purpose sampling, carried out in a tertiary-level hospital in the city of Campinas, state of São Paulo, Brazil. METHODS: This was a cross-sectional pre and post-test intervention among healthcare professionals working in the intensive care unit and emergency department of a large hospital. The training was carried out using an in situ simulation scenario and the participants answered pre and post-tests consisting of a 20-item questionnaire about the new protocol. RESULTS: The paired-sample t test demonstrated that there was a significant increase in test score (t = -19.06; P < 0.001), from before the training (M = 8.62; standard deviation, SD = 3.53) to after the simulation training (M = 17.02; SD = 1.76). CONCLUSIONS: The simulated training had a positive impact on the healthcare professionals' acquisition of the COVID-19 protocol. We also demonstrated that in situ simulation training was an efficient tool for implementing new protocols, thus bringing benefits to healthcare systems, professionals and patients.

Volumetric capnography as a noninvasive diagnostic procedure in acute pulmonary thromboembolism.

Pulmonary thromboembolism is a common condition. Its diagnosis usually requires pulmonary scintigraphy, computed angiotomography, pulmonary arteriography and, in order to rule out other diagnoses, the measurement of D-dimer levels. Due to the fact that these diagnostic methods are not available in most Brazilian hospitals, the validation of other diagnostic techniques is of fundamental importance. We describe a case of a woman with chronic pulmonary hypertension who experienced a pulmonary thromboembolism event. Pulmonary scintigraphy, computed angiotomography and pulmonary arteriography were used in the diagnosis. The D-dimer test result was positive. Volumetric capnography was performed at admission and after treatment. The values obtained were compared with the imaging test results.

Capnografia volumétrica como auxílio diagnóstico não-invasivo no tromboembolismo pulmonar agudo / Volumetric capnography as a noninvasive diagnostic procedure in acute pulmonary thromboembolism

O tromboembolismo pulmonar é uma situação freqüente que pode ser diagnosticada pela cintilografia pulmonar, angiotomografia computadorizada, arteriografia pulmonar e, como método de exclusão, dosagem do dímero-D. Como estes exames nem sempre estão disponíveis, a validação de outros métodos diagnósticos é fundamental. Relata-se o caso de uma paciente com hipertensão pulmonar crônica, agudizada por tromboembolismo pulmonar. Confirmou-se o diagnóstico por cintilografia, angiotomografia computadorizada, arteriografia pulmonar; a dosagem do dímero-D resultou positiva. A capnografia volumétrica associada à gasometria arterial foi realizada na admissão e após o tratamento. As variáveis obtidas foram comparadas com os resultados dos exames de imagem.

Insuficiência respiratória aguda como manifestação da síndrome de eosinofilia-mialgia associada à ingestão de L-triptofano / Acute respiratory failure as a manifestation of eosinophilia-myalgia syndrome associated with L-tryptophan intake

A síndrome da eosinofilia-mialgia foi descrita em 1989 em pacientes que apresentavam mialgia progressiva e incapacitante e eosinofilia sérica, nos líquidos e secreções. A maioria dos pacientes relatava uso prévio de L-triptofano. Sintomas respiratórios são relatados em até 80 por cento dos casos, eventualmente como manifestação única. O tratamento inclui suspensão da droga e corticoterapia. Relatamos o caso de uma mulher de 61 anos com insuficiência respiratória aguda após uso de L-triptofano, hidroxitriptofano e outras drogas. A paciente apresentava eosinofilia no sangue, lavado broncoalveolar e derrame pleural. Após a suspensão da medicação e corticoterapia, houve melhora clínica e radiológica em poucos dias.

Eosinophilia-myalgia syndrome was described in 1989 in patients who presented progressive and incapacitating myalgia and eosinophilia in blood, fluids and secretions. Most patients report previous L-tryptophan intake. Respiratory manifestations are found in up to 80 percent of the cases, occasionally as the only manifestation. Treatment includes drug discontinuation and administration of corticosteroids. Here, we describe the case of a 61-year-old female admitted with acute respiratory failure after using L-tryptophan, hydroxytryptophan and other drugs. The patient presented eosinophilia, together with elevated eosinophil counts in the bronchoalveolar lavage and pleural effusion. After discontinuation of the drugs previously used, corticosteroids were administered, resulting in clinical and radiological improvement within just a few days.

Association between paracoccidioidomycosis and tuberculosis: reality and misdiagnosis.

OBJECTIVE: To evaluate the frequency of the real association between paracoccidioidomycosis (PCM) and tuberculosis (TB) as well as the rate of previous TB misdiagnosis in individuals with PCM among the patients treated in the Pulmonology Division of the State University of Campinas Hospital das Clínicas, Campinas, Brazil. METHODS: A retrospective study of 227 adult patients with PCM (chronic form) treated between 1980 and 2005. RESULTS: Of the 227 patients studied, 36 (15.8%) had been previously treated for TB. However, only 18 (7.9%) presented positive sputum smear microscopy results. The remaining 18 (7.9%) neither presented positive sputum smear microscopy nor showed improvement after receiving specific anti-TB treatment. CONCLUSION: Although the existence of an association between PCM and TB has been documented in the literature, misdiagnosis is common due to the superimposition of and the similarity between their clinical and radiographic presentations, thereby warranting the need for bacteriological diagnosis before initiating specific treatment.

Associação entre paracoccidioidomicose e tuberculose: realidade e erro diagnóstico / Association between paracoccidioidomycosis and tuberculosis: reality and misdiagnosis

OBJETIVO: Avaliar a freqüência da real associação entre paracoccidioidomicose (PCM) e tuberculose (TB) e a freqüência do diagnóstico errôneo prévio de TB em doentes com PCM entre os pacientes atendidos na Disciplina de Pneumologia do Hospital das Clínicas da Universidade Estadual de Campinas, Campinas (SP). MÉTODOS: Estudo retrospectivo de 227 pacientes adultos com diagnóstico confirmado de PCM (forma crônica) entre 1980 e 2005. RESULTADOS: Dos 227 casos, 36 (15,8 por cento) haviam sido tratados anteriormente para TB. Porém, apenas 18 (7,9 por cento) apresentaram baciloscopia positiva. Os outros 18 (7,9 por cento) nunca tiveram o diagnóstico confirmado pela baciloscopia nem responderam ao tratamento específico para TB. CONCLUSÃO: Apesar de a associação entre PCM e TB existir e estar documentada na literatura, o erro diagnóstico é bastante comum, haja vista a sobreposição e similaridade das apresentações clínicas e radiológicas dessas duas doenças, havendo, portanto, a necessidade do diagnóstico bacteriológico antes de se iniciar o tratamento específico.

[Use of corticosteroids after esophageal dilations on patients with corrosive stenosis: prospective, randomized and double-blind study]. / O uso de corticoesteróides após dilata o esofágica em pacientes portadores de estenose por substâncias corrosivas: estudo prospectivo, randomizado e duplo-cego.

OBJECTIVE: To determine triancinolone intralesional injections effects in association with esophageal dilations in corrosive stenosis cases, by means of a double-blind and randomized study. METHOD: Fourteen adults patients (6 men and 8 women) with severe esophageal corrosive stenosis were randomized in two groups: Group A: treated by esophageal dilations and posterior triancinolone 10 mg/ml intralesional injection; Group B: treated by esophageal injections and posterior saline solution 0,9% injection (placebo). New applications were made based on the patient symptomatology. It had been analysed dilation frequency, obtained diameters and dysphagia before and after the research, for 12 months. RESULTS: Eleven patients had ingested sodium hydroxide, two had ingested ammoniac and one had taken muriatic acid. There was no statistic difference (p > 0.05) in dilation frequency and dysphagia between the groups. However, an improvement in obtained diameter was observed in the corticosteroids group in comparison with control group (p < 0.05). By comparing groups before and after steroids, the final results were very favorable in group A CONCLUSION: Multiple intralesional injections of triancinolone hexacetonide 10 mg/ml in association with esophageal dilations increase obtained diameters in succeeding sessions.

O uso de corticoesteróides após dilataçäo esofágica em pacientes portadores de estenose por substâncias corrosivas: estudo prospectivo, randomizado e duplo-cego / Use of corticosteroids after esophageal dilations on patients with corrosive stenosis: prospective, randomized and double-blind study

OBJETIVOS: Determinar, através de um estudo randomizado e duplo-cego, o efeito de injeções intralesionais de triancinolona associadas à dilataçäo esofágica nos casos de estenose corrosiva. MÉTODOS: Quatorze pacientes adultos (seis homens e oito mulheres) portadores de graves estenoses corrosivas do esôfago foram randomizados em dois grupos: Grupo A: tratados com dilataçäo esofágica e posterior injeçäo intralesional de triancinolona 10 mg/ml; Grupo B: tratados com dilataçäo esofágica e posterior injeçäo de soluçäo fisiológica 0,9 por cento (placebo). Aplicações subseqüentes foram feitas baseadas na sintomatologia do paciente. Foram analisados: a freqüência de dilatações, diâmetros obtidos e disfagia antes e após a pesquisa, durante 12 meses. RESULTADOS: Em nosso estudo, onze pacientes ingeriram soda cáustica, dois ingeriram amoníaco e um tomou ácido muriático. Näo houve diferença estatisticamente significativa (p > 0,05) em relaçäo à freqüência de dilatações e à disfagia entre os grupos estudados. Entretanto, foi observada melhora no diâmetro obtido no grupo que recebeu corticoesteróides, em relaçäo ao grupo controle (p < 0,05). Comparando-se antes e depois do uso de corticoesteróides, o resultado foi muito favorável (p < 0,01) no grupo A. CONCLUSÕES: O uso de múltiplas injeções intralesionais de hexacetonido de triancinolona 10 mg/ml associado à dilatações esofágicas é eficaz no aumento do diâmetro obtido nas sessöes subseqüentes
