Association between voice symptoms and college professors' home working conditions during online classes in times of COVID-19 pandemic / Asociación entre síntomas vocales y condiciones de trabajo en casa durante las clases online en tiempos de COVID-19 de docentes universitarios

Introduction. Due to the COVID-19 pandemic, teaching conditions changed around the world from in-person classes to online classes, which also determined changes on teachers' working conditions. Method: Exploratory cross-sectional study with the aim of determining the association between two voice symptoms (vocal fatigue and throat pain) with home working conditions during online classes in times of COVID-19 pandemic. Professors answered an online survey including 27 questions about four components: sociodemographic factors, characteristics of home working, quarantine characteristics, and health conditions (including voice functioning). Results: 177 college professors from Argentina, Colombia, and Chile participated in this study. First, incidence of vocal fatigue, during online classes in times of COVID-19 pandemic, represented around 50%. Although throat pain had a smaller incidence, it was also important (35%). Second, days in quarantine, number of classes per week, people living with during quarantine, and history of vocal fatigue before quarantine were important associated factors of vocal fatigue. Third, important associated factors of throat pain were number of classes per week, level of stress, years of experience, and history of throat pain before quarantine. Conclusion: Similar to pre-COVID-19, vocal fatigue and throat pain were frequently reported voice symptoms among college professors. Associated factors of these symptoms included years of experience, number of classes per week, stress, people living with during quarantine due to COVID-19, and history of voice symptoms. Workplace Health Promotion programs should include activities that facilitate a healthy occupational voice use during and post-COVID-19 pandemic, considering the implications of online teaching on teachers' health and safety

Introducción: Debido a la pandemia del COVID-19, las condiciones de ense-ñanza-aprendizaje cambiaron alrededor del mundo, pasando de clases presen-ciales a clases virtuales, lo que también determinó cambios en las condiciones de trabajo docente. Métodos: Estudio transversal exploratorio que tuvo como propósito determinar la asociación entre dos síntomas de voz (fatiga vocal y dolor de garganta) con las con-diciones de trabajo docente durante las clases virtuales en tiempos de COVID-19. Los profesores diligenciaron una encuesta virtual que incluyó 27 preguntas sobre los siguientes cuatro componentes: factores sociodemográficos, características del tra-bajo en casa, características de la cuarentena, y condiciones de salud (incluyendo funcionamiento vocal). Resultados: 177 profesores universitarios de Argentina, Colombia y Chile parti-ciparon en este estudio. Primero, la incidencia de la fatiga vocal durante las clases virtuales en tiempos de COVID-19 representó alrededor del 50%. Aunque el dolor de garganta tuvo una menor incidencia, también fue importante (35%). Segundo, los días en cuarentena, número de clases por semana, personas con las que vivió durante la cuarentena, y los antecedentes de fatiga vocal antes de la cuarentena estuvieron estadísticamente asociados a la fatiga vocal. Tercero, los factores asociados al dolor de garganta fueron el número de clases semanales, los niveles de estrés, los años de experiencia y los antecedentes de dolor de garganta antes de la cuarentena.Conclusión: Similar a hallazgos previos al COVID-19, la fatiga vocal y el dolor de garganta son síntomas vocales frecuentemente reportados en docentes universitarios. Factores asociados de estos síntomas incluyen años de experiencia, número de clases semanales, estrés, personas con las que vivió durante la cuarentena y antecedentes de estos síntomas vocales antes del trabajo en casa. Los Programas de Promoción de la Salud en los Lugares de Trabajo deben incluir actividades que faciliten el uso ocupacional saludable de la voz durante y después del COVID-19, considerando las implicaciones de la enseñanza virtual en la salud y seguridad de los profesores.

Síndrome de Miller Fisher: relato de caso / Miller Fisher syndrome: case report

A síndrome de Miller Fisher é uma desmielinização dos nervos cranianos e periféricos, gerando graves consequências para o paciente, como, por exemplo, redução ou ausência dos reflexos, paralisia do III, IV e VI nervos cranianos e ataxia. Este relato descreveu o caso de uma mulher de 51 anos, natural e procedente de Penápolis (SP), admitida em um hospital de Araçatuba (SP) com quadro de arreflexia, ataxia e oftalmoplegia. No contexto clínico, foi suspeitada a hipótese de síndrome de Miller Fisher e, assim, começou o processo de investigação, com base nos critérios diagnósticos. O caso foi diagnosticado como síndrome de Miller Fisher, e o tratamento teve início.

Miller Fisher Syndrome is a demyelinating disease affecting cranial and peripheral nerves, leading to severe problems to the patient, such as reduced or absent reflexes, III, IV and VI cranial nerves palsy, and ataxia. This report describes the case of a 51-year-old woman from the city of Penápolis, in the state of São Paulo, who was admitted to the hospital in the city of Araçatuba, in the same state, with ataxia, areflexia and ophthalmoplegia. In the clinical context, the suspicion of Miller Fisher Syndrome was raised, and then investigation ensued for the disease, based on the diagnostic criteria. After evaluation, Miller Fisher Syndrome was confirmed and treatment was started.

Síndrome de Lemierre: relato de caso / Lemierre syndrome: case report

síndrome de Lemierre caracteriza-se pela tromboflebite séptica da veia jugular interna, após uma orofaringite, com embolização séptica para o pulmão ou outros órgãos. Neste relato de caso, apresentamos uma paciente feminina, 37 anos de idade, com história de edema e dor em hemiface direita há três dias, associada a fadiga e dispneia progressiva há um dia. História de extração dentária do elemento 48 há três dias. No exame físico admissional, apresentava-se taquipneica, saturando 60% (em ar ambiente), com edema em ângulo da mandíbula direita, redução difusa do murmúrio vesicular e panturrilhas sem empastamento. Angiotomografia de tórax e exames laboratoriais foram compatíveis com quadro de embolia séptica, e tomografia computadorizada da cervical corroborou o diagnóstico de tromboflebite séptica da veia jugular interna. Foi tratada com antibióticos e sintomáticos. A síndrome de Lemierre afeta mais homens jovens e tem embolização para o pulmão em até 97% dos casos. Extrações dentárias raramente podem ser a etiologia dessa síndrome. A tomografia computadorizada é o método de imagem mais utilizado no diagnóstico, e o tratamento é, essencialmente, com antibióticos; portanto, a abordagem cirúrgica é raramente necessária

Lemierre syndrome is characterized by septic thrombophlebitis of the internal jugular vein, after an oropharyngeal infection, with septic embolization to the lungs or other organs. This case report describes a 37-year-old female patient who presented with edema and pain in the right hemiface with onset 3 days previously and progressive fatigue and dyspnea since the previous day. She had had tooth 48 extracted 3 days previously. Physical examination at admission found tachypnea, with 60% saturation (in room air), edema at the angle of the right mandible, diffuse reduction of vesicular murmur, and calves free from clubbing. Angiotomography of the chest and laboratory tests were compatible with septic emboli, and cervical computed tomography confirmed a diagnosis of septic thrombophlebitis of the internal jugular vein. She was managed with antibiotics and given treatment for her symptoms. Lemierre syndrome most often occurs in young men and there is embolization to the lungs in up to 97% of cases. Rarely, the etiology of this syndrome may be tooth extraction. Computed tomography is the imaging method most often used for diagnosis and treatment is basically antibiotic. Surgery is thus rarely necessary

Impacto do uso da prova rápida para estreptococo beta-hemolítico do grupo A no diagnóstico e tratamento da faringotonsilite aguda em pronto-socorro de Pediatria / Impact of the rapid antigen detection test in diagnosis and treatment of acute pharyngotonsillitis in a Pediatric emergency room / Impacto del uso de la prueba rápida para estreptococos beta-hemolíticos del grupo A en el diagnóstico y tratamiento de la faringotonsilitis en emergencia de Pediatría

OBJETIVO: Avaliar o impacto da realização rotineira da prova rápida para pesquisa de estreptococo do grupo A no diagnóstico e tratamento da faringotonsilite aguda em crianças. MÉTODOS: Estudo prospectivo e observacional que contou com a utilização de protocolo de pesquisa estabelecido na Unidade de Emergência do Hospital Universitário da Universidade de São Paulo para o atendimento de crianças e adolescentes com faringotonsilite aguda. RESULTADOS: Com base na avaliação clínica, dos 650 pacientes estudados, antimicrobianos seriam prescritos para 389 indivíduos (59,8%) e, com o uso da pesquisa de estreptococo do grupo A, foram prescritos em 286 pacientes (44,0%). Das 261 crianças que não receberiam antibiótico pelo quadro clínico, 111 (42,5%) tiveram pesquisa de estreptococo do grupo A positiva. O diagnóstico baseado no quadro clínico apresentou sensibilidade de 61,1%, especificidade de 47,7%, valor preditivo positivo de 44,9% e valor preditivo negativo de 57,5%. CONCLUSÕES: O diagnóstico clínico da faringotonsilite estreptocócica mostrou baixa sensibilidade e especificidade. O uso rotineiro da prova rápida para pesquisa de estreptococo permitiu a redução do uso de antibióticos e a identificação de um grupo de risco para as complicações da infecção estreptocócica, pois 42,5% dos pacientes com prova rápida positiva não receberiam antibióticos, se levado em consideração apenas o diagnóstico clínico.

OBJECTIVE: To evaluate the impact of the routine use of rapid antigen detection test in the diagnosis and treatment of acute pharyngotonsillitis in children. METHODS: This is a prospective and observational study, with a protocol compliance design established at the Emergency Unit of the University Hospital of Universidade de São Paulo for the care of children and adolescents diagnosed with acute pharyngitis. RESULTS: 650 children and adolescents were enrolled. Based on clinical findings, antibiotics would be prescribed for 389 patients (59.8%); using the rapid antigen detection test, they were prescribed for 286 patients (44.0%). Among the 261 children who would not have received antibiotics based on the clinical evaluation, 111 (42.5%) had positive rapid antigen detection test. The diagnosis based only on clinical evaluation showed 61.1% sensitivity, 47.7% specificity, 44.9% positive predictive value, and 57.5% negative predictive value. CONCLUSIONS: The clinical diagnosis of streptococcal pharyngotonsillitis had low sensitivity and specificity. The routine use of rapid antigen detection test led to the reduction of antibiotic use and the identification of a risk group for complications of streptococcal infection, since 42.5% positive rapid antigen detection test patients would not have received antibiotics based only on clinical diagnosis.

OBJETIVO: Evaluar el impacto de la realización de rutina de la prueba rápida para investigación de estreptococos del grupo A en el diagnóstico y tratamiento de la faringotonsilitis aguda en niños.

RESULTADOS: Con base en la evaluación crítica, de los 650 pacientes estudiados, antimicrobianos serían prescritos a 389 individuos (59,8%) y, con el uso de la investigación de estreptococos del grupo A se los prescribieron a 286 pacientes (44,0%). De los 261 niños que no recibirían antibióticos por el cuadro clínico, 111 (42,5%) tuvieron investigación de estreptococos del grupo A positiva. El diagnóstico basado en el cuadro clínico presentó sensibilidad del 61,1%, especificidad del 47,7%, valor predictivo positivo del 44,9% y valor predictivo negativo del 57,5%, CONCLUSIONES: En este estudio, el diagnóstico clínico de la faringotonsilitis estreptocócica mostró baja sensibilidad y especificidad. El uso de rutina de la prueba rápida para investigación de estreptococos permitió la reducción del uso de antibióticos y la identificación de un grupo de riesgo para las complicaciones de la infección estreptocócica, pues el 42,5% de los pacientes con prueba rápida positiva no recibirían antibióticos si se llevara en consideración solamente el diagnóstico clínico.

Variabilidad e idoneidad en el tratamiento antimicrobiano de las faringoamigdalitis agudas pediátricas en Asturias, España / Variability of antibiotic treatment in paediatric acute pharyngotonsillitis in Asturias, Spain

Introducción. Las faringoamigdalitis agudas suponen un importante porcentaje de las consultas pediátricas y una de las principales causas de prescripción antibiótica. Nuestro objetivo fue analizar los hábitos de prescripción antimicrobiana en niños diagnosticados con faringoamigdalitis aguda en servicios de urgencias hospitalarios y consultas pediátricas de atención primaria en Asturias (España). Métodos. Estudio descriptivo multicéntrico que evalúa pacientes pediátricos diagnosticados con faringoamigdalitis aguda en los servicios de urgencias de 5 hospitales y en 80 consultas pediátricas de atención primaria. La idoneidad de las prescripciones se estableció por comparación con estándares de referencia. Resultados. Se incluyeron 563 niños con faringoamigdalitis agudas, 49,7% en atención primaria (IC 95% 45,6-53,8%), a los largo de 30 días no consecutivos (6,8% de las consultas pediátricas). Se prescribieron antibióticos en el 75,5% de las faringoamigdalitis (IC 95% 71,9-79,0%) [(78,3% en los menores de 3 años (IC 95% 71,8-84,8%)]. El antibiótico más indicado fue la amoxicilina [39,1% de los casos que recibieron antibioterapia (IC 95% 34,4-43,7%)]. Se encontraron diferencias signifcativas en el porcentaje de prescripción antibiótica entre atención primaria y urgencias hospitalarias (70,0% contra 80,9%, p= 0,003). El tratamiento prescrito se consideró de primera elección en el 43,3% de los tratados (IC 95% 38,6-48,0%) e inadecuado en el 56,0% (IC 95% 51,3-60,7%). Conclusiones. Pese a que la mayoría de las faringomigdalitis agudas pediátricas son de probable etiología vírica, tres cuartas partes de ellas reciben tratamiento antibiótico en nuestro medio, siendo la elección inapropiada en más de la mitad de los casos.

Introduction. Acute pharyngotonsillitis accounts for a large portion of antibiotic prescriptions in pediatric offces. Our aim was to analyze the antimicrobial prescription habits for acute pharyngotonsillitis in children from hospital emergency departments and primary care pediatric clinics in Asturias (Spain). Methods. Multicenter descriptive study evaluating pediatric patients with a diagnosis of acute pharyngotonsillitis in 5 hospital emergency departments and 80 pediatric primary care clinics. Appropriateness of prescription was established by comparing with reference standards. Results. Five hundred sixty-three children with acute pharyngotonsillitis [49.7% in primary care CI 95% 45.6-53.8%)] were included along 30 nonconsecutive days. Antibiotics were prescribed in 75.5% of cases (95% CI 71.9-79.0%) [78.3% in children under 3 years of age (95% CI 71.8-84.8%)]. Amoxicillin was the antibiotic most frequently prescribed [39.1% (95% CI 34.4-43.7%)]. Signifcant differences in the frequency or antibiotic prescription were found between primary care and hospital emergency departments (70% vs. 80.9%, p= 0.003). The treatment prescribed was considered frst choice in 43.3% (95% CI 38.6-48.0%) and inappropriate in 56.0% (95% CI 51.3-60.7%). Conclusions. Although in most cases pediatric acute pharyngotonsillitis is viral in origin, three out of four are treated with antibiotics. Treatment was inappropriate in more than half of the cases in our study.

Group A Sstreptococcus virulence factors genes in north India & their association with emm type in pharyngitis.

Background & objectives: Group A streptococcal (GAS) pharyngitis, especially among children, leads to high prevalence of rheumatic fever (RF)/rheumatic heart disease (RHD) in India, as compared to the western world where invasive diseases are common. GAS encodes numerous virulence factors that cause diseases by exhibiting extraordinary biological diversity. Hence, we studied the virulence factors genes of GAS isolated from the throat of children with pharyngitis and also asymptomatic carriers. Methods: Fifty GAS isolates cultured from throats of north Indian children aged 5-15 yr with mild pharyngitis (20), severe pharyngitis (24) and asymptomatic pharyngeal carriers (6), during 2000-2003 along with reference M1 strain were emm typed and characterized for virulence factors genes by PCR. The presence of virulence factors was also checked for their association with emm type in pharyngitis. Results: Twenty emm types, six sequence types, and one non-typeable strain were found circulating in north India. The five most prevalent types were emm 74 (12%), 11 & StI129 (8% each) and emm 68 and NS292 (6% each). The spe B gene was found to be significantly higher (P=0.0007) in opacity factor (OF) negative isolates. emm 3, 11, 77, 86, 87, 109 and StI129 showed maximum virulence factors genes. Interpretation & conclusions: GAS isolates collected from throats of children from north India possess highly virulent antigens. This study also supports concept of isolate-associated virulence rather than type relatedness.

Embolia pulmonar séptica secundária à tromboflebite jugular: um caso de síndrome de Lemierre / Septic pulmonary embolism secondary to jugular thrombophlebitis: a case of Lemierre's syndrome

A síndrome de Lemierre é caracterizada pela infecção aguda da orofaringe, complicada por trombose venosa jugular interna secundária à tromboflebite séptica, e por infecções metastáticas a vários órgãos distantes-mais freqüentemente os pulmões. Relatamos um caso de síndrome de Lemierre em uma mulher de 56 anos que se apresentou com massa cervical à direita e febre. Trombose venosa jugular interna foi demonstrada na ecografia. A tomografia computadorizada de tórax revelou múltiplas opacidades em ambos os pulmões. Uma biópsia pulmonar cirúrgica foi realizada por suspeita de metástases pulmonares. O exame anatomopatológico revelou êmbolos sépticos em parênquima pulmonar. Retrospectivamente, a paciente relatou história de faringite duas semanas antes da hospitalização. Após o diagnóstico, foi tratada com antibióticos de amplo espectro (cefuroxima por 7 dias e azitromicina por 5 dias e, posteriormente, devido à persistência de febre, cefepime por 7 dias). A tomografia computadorizada de tórax, realizada um mês após, mostrou resolução das opacidades.

Lemierre's syndrome is characterized by acute oropharyngeal infection, complicated by internal jugular venous thrombosis secondary to septic thrombophlebitis, and by metastatic infections in various distant organs-most commonly in the lungs. We report a case of Lemierre's syndrome in a 56-year-old female who presented with right-sided neck mass and fever. Right internal jugular venous thrombosis was demonstrated on an ultrasound. A computed tomography scan of the chest revealed multiple opacities throughout both lungs. An open surgical biopsy was performed due to suspicion of pulmonary metastases. Anatomopathological examination revealed septic emboli in lung parenchyma. Retrospectively, the patient reported a history of pharyngitis two weeks prior to hospitalization. After the diagnosis had been made, the patient was treated with broad-spectrum antibiotics (cefuroxime for 7 days and azithromycin for 5 days; subsequently, because fever persisted, cefepime for 7 days). One month later, a computed tomography scan of the chest revealed resolution of the opacities.

Lemierre Syndrome: A Case of Postanginal Sepsis

Lemierre syndrome is a rare disease that's characterized by internal jugular vein thrombosis and septic emboli. These symptoms typically develop after acute oropharyngeal infection by Fusobacterium necrophorum1). Although this syndrome is less frequently seen in modern times due to the availability of antibiotics, physicians must be aware of the syndrome in order to initiate prompt antibiotics therapy, including coverage of the anerobic organisms. We discuss here the case of an 18-year-old female with Lemierre syndrome and we review the relevant literature on this syndrome.

Microbiological diagnosis of streptococcal pharyngitis: lacunae and their implications.

Post-streptococcal sequelae, especially acute rheumatic fever/rheumatic heart disease continue to occur in significant proportions in many parts of the world. Despite several attempts with various intervention strategies, little success has been achieved in the control of acute rheumatic fever/rheumatic heart disease in India. The success of the control programmes depends upon timely primary prophylaxis with benzathine penicillin for which a microbiological confirmation of group A streptococcal pharyngitis is essential. Isolation of beta hemolytic streptococci from throat cultures and their identification as GAS in the laboratory, clinches the microbiological diagnosis while demonstration of a 'significant rise' in antibody titers such as Anti-streptolysin O and Anti-deoxyribonuclease B differentiates it from a group A streptococcal carrier state or pharyngitis of a viral etiology. Despite the easiness with which these can be achieved, many laboratories in India are not equipped to do so. Enhancing bacteriological and serological facilities in laboratories across the country will drastically improve the clinician's ability to diagnose bona fide GAS pharyngitis and help to institute penicillin prophylaxis at the appropriate time. This will go a long way in enhancing the compliance to penicillin prophylaxis which is the cornerstone of any RF/RHD control program.

Aumento en la prevalencia de estreptococos beta hemoliticos en hisopados faringeos en Buenos Aires / High prevalence of beta hemolytic streptococci isolated from throat swabs in Buenos Aires

El estreptococo beta hemolítico grupo A (EBHGA) es el agente bacteriano más frecuentemente aislado en casos de faringoamigdalitis. Otros estreptococos beta hemolíticos no A también pueden producir esta enfermedad. Ante el elevado número de aislamientos obtenidos en el año 2004 decidimosrealizar un estúdio con el objeto de evaluar la prevalência de estos microorganismos durante um períodod de 5 años. Se incluyeron todos los cultivos de hisopados faríngeos que se realizaron con idéntica metodologia. Se considero ninõs a los comprendidos entre 6 meses y 18 años de edad, y adultos a los mayores de 18 años. Los aislamientos fueron identificados según la metodologia habitual. La determinación de grupo se realizo mediante la aglutinación con partículas de látex. La recuperación de EBHGA fue significativamente mayor enniños en relación a los adultos. En el año 2004 se obtuvo una recuperación significamente mayor de EBHGA, EBHGC y EBHGG en niños y de EBHGA y EBHGG en adultos respecto respecto de los años anteriores. El aislamiento de EBHGG fue mayor en adultos. El 18.9% y el 55.8% de los estreptococos beta hemolíticos aislados en niños y adultos espectivamente no pertenecieron al grupo A. El incremento en la prevalência de estreptococos betahemolíticos refuerza la buena práctica de realizar cultivos en adultos y niños así como la correcta búsqueda en el laboratório de bacteriología de los estreptococos beta hemolíticos no pertenecientes al grupo A.

Identification of serogroups of beta hemolytic streptococci in children with tonsillo-pharyngitis.

Rheumatic fever and post streptococcal glomerulonephritis are common sequelae of beta hemolytic streptococci among Bangladeshi children. The occurrence of these serious complications of beta hemolytic streptococcal throat infections are related to the epidemiology of group A beta hemolytic streptococci. Little is known about the epidemiology of beta hemolytic streptococci in Bangladesh. We have studied 6890 school boys and girls of Narayangonj to find out the prevalence of beta hemolytic streptococcal infections of throat. From them we selected 2175 children, who were suffering from tonsillo-pharyngitis. This cross sectional study was conducted during March-December 1999. All statistical analysis was done by using statistical package SPSS windows version 8. The mean (SD) age of the children was 11.1 (3.3) years. Four hundred and twenty eight isolates of beta hemolytic streptococci were recovered from tonsillo-pharyngeal swab cultures obtained from 428 children. Among the isolated beta hemolytic streptococci, 92 (21.5%) belonged to group A, 5 (1.2%) to group B, 14 (3.3%) to group C and 317 (74.0%) to group G. These findings demonstrated the predominance of group G followed by A infection among school children. Therefore special attention should be paid not only to group A but also to group G. Further studies to determine prevalence of M serotypes are necessary.
