ABSTRACT

Fundamento: En Cuba, durante la pandemia de COVID-19, se puso a prueba la importancia de las escalas clínicas para el tratamiento de pacientes adultos con amigdalitis aguda por no contar con pruebas de detección rápida de antígenos, sin embargo, su uso sigue siendo controversial. Objetivo: Describir los resultados de la aplicación de la escala Centor en la atención a pacientes con amigdalitis aguda durante la COVID-19. Metodología: Se realizó un estudio de serie de casos y se incluyeron los pacientes con amigdalitis aguda diagnosticados en un período de dos años en la consulta externa de Otorrinolaringología del Hospital General Provincial Camilo Cienfuegos, Sancti Spíritus, Cuba. A todos se les aplicó la escala Centor. Resultados: Se incluyeron 114 pacientes. La media de edad fue de 28.9 + 18.7 años, más de la mitad de los pacientes tenían antecedentes de amigdalitis crónica y adenoiditis crónica y eran fumadores activos. Aproximadamente 2 de cada 5 pacientes tuvieron puntuaciones <3 según la escala Centor. Conclusiones: La amigdalitis aguda fue un problema de salud durante la COVID-19 y la escala Centor fue una importante herramienta para la toma de decisiones terapéuticas en pacientes con amigdalitis aguda, aun en condiciones de ausencia de pruebas confirmatorias.


Background: In Cuba, during the COVID-19 pandemic, the clinical scales for adult patients treatment with acute tonsillitis were put under test for not having rapid antigen detection tests, however, its use is still controversial. Objective: To describe the Centor scale application results in the care of patients with acute tonsillitis during COVID-19. Methodology: A case series study was conducted and it included acute tonsillitis patients diagnosed over a two year period in the Otorhinolaryngology external consultation at Camilo Cienfuegos Provincial General Hospital, Sancti Spíritus, Cuba. The Centor scale was applied to all of them. Results: It included 114 patients. The average age was 28.9 + 18.7 years, more than half of the patients had previous history of chronic tonsillitis and chronic adenoiditis and they were active smokers. Approximately 2 out of 5 patients had scores <3 according to the Centor scale. Conclusions: Acute tonsillitis was a health problem during COVID-19 and the Centor scale was an important tool for therapeutic decision in acute tonsillitis patients, even in absence of confirmatory evidence.

ABSTRACT

Resumen INTRODUCCIÓN: Las úlceras de Lipschütz son una causa infrecuente de úlcera genital, de alivio espontáneo y casi siempre benignas, aunque en algunas pacientes pueden dejar cicatrices genitales. Lo común es que aparezcan en mujeres jóvenes, antes del inicio de la vida sexual activa, en coincidencia con un cuadro catarral o pseudogripal. CASO CLÍNICO: Paciente de 18 años con una úlcera vulvar dolorosa, coincidente con un episodio de amigdalitis aguda y fiebre de 38 ºC. La paciente negó haber tenido relaciones sexuales. La úlcera alcanzó 3 a 4 cm, profunda, purulenta, con apertura del labio menor derecho y con importante componente necrótico. Para el control del dolor se le indicaron: corticoides, doxiciclina oral, crema con lidocaína y antiinflamatorios. Los análisis de laboratorio descartaron que se tratara de infección de trasmisión sexual. Al término del esquema terapéutico prescrito la evolución fue favorable, con desaparición de los síntomas, pero con una secuela: apertura del labio mayor derecho. CONCLUSIONES: La úlcera de Lipschütz es una causa infrecuente de úlcera vulvar. Su tratamiento consiste en el control de los síntomas y casi siempre se cura en el transcurso de 4 a 6 semanas, sin dejar lesiones. El diagnóstico solo puede establecerse luego de excluir otras causas más frecuentes de úlcera vulvar.


Abstract INTRODUCTION: Lipschütz ulcers are an infrequent cause of genital ulcer, of spontaneous relief and almost always benign, although in some patients they may leave genital scars. They usually appear in young women, before the onset of active sexual life, coinciding with a catarrhal or flu-like condition. CLINICAL CASE: 18-year-old female patient with a painful vulvar ulcer, coinciding with an episode of acute tonsillitis and fever of 38 ºC. The patient denied having had sexual intercourse. The ulcer was 3 to 4 cm, deep, purulent, with opening of the right labium minora and with a significant necrotic component. For pain control she was prescribed corticosteroids, oral doxycycline, lidocaine cream and anti-inflammatory drugs. Laboratory tests ruled out sexually transmitted infection. At the end of the prescribed therapeutic scheme the evolution was favorable, with disappearance of symptoms, but with a sequel: opening of the right labium majus. CONCLUSIONS: Lipschütz ulcer is a rare cause of vulvar ulcer. Its treatment consists of symptom control and it almost always heals within 4 to 6 weeks, leaving no lesions. The diagnosis can only be established after other more frequent causes of vulvar ulceration have been excluded.

ABSTRACT

La tuberculosis es la primera causa de mortalidad infectocontagiosa a nivel mundial. La tuberculosis pulmonar corresponde a la presentación más frecuente, sin embargo, el 15 % de los casos cursan con infección extrapulmonar, siendo raro el compromiso amigdalino. Este reporte de caso describe a un paciente de 39 años con odinofagia recurrente secundaria a amigdalitis por Mycobacterium tuberculosis, un raro caso de tuberculosis extrapulmonar. La amigdalitis es una infección leve y frecuente de la vía aérea superior, que responde adecuadamente al manejo antibiótico; sin embargo, cuadros recurrentes y prolongados, manifestaciones atípicas o pobre respuesta a la antibioticoterapia son características que obligan a la búsqueda de diagnósticos diferenciales, lo que lleva a considerar la presencia de Mycobacterium tuberculosis como agente etiológico, especialmente en países con alto índice de tuberculosis como Colombia


Tuberculosis is the leading cause of infectious mortality worldwide. The pulmonary one corresponds to the most frequent presentation, however up to 15% of tuberculosis cases present extrapulmonary involvement, tonsillar tuberculosis being rare. The following is a case report of a 39-year-old patient with recurrent odynophagia secondary to Mycobacterium tuberculosis tonsillitis, a rare form of extrapulmonary tuberculosis. Tonsillitis is a benign and extremely common infection of the upper airway. Such patients benefit from systemic antibiotics, although, recurrent episodes, prolonged odynophagia, atypical manifestations, or poor response to antimicrobial therapy forces consideration of diagnostic possibilities other than the obvious, including Mycobacterium tuberculosis as the etiological agent, especially in countries with the highest rates of tuberculosis.

ABSTRACT

Abstract We report an unexpected difficult airway in a patient with unrecognized lingual tonsillar hypertrophy. A 54-year-old hypertensive woman presented for resection of a mediastinal mass under general anesthesia (GA). After induction, mask ventilation was impossible. Laryngeal mask airway (LMA) was used, achieving suboptimal ventilation. Fiberoptic intubation through LMA was attempted but tube advancement was hindered by a protrudingmass. Finally, intubation was achieved using the Frova introducer. After completion of the surgery, the patient was transferred, intubated, to the postanesthesia care unit. Ear, nose, and throat assessment concluded that the mass was a hyper-trophied lingual tonsil. Unexpected lingual tonsillar hypertrophy can complicate GA, making mask ventilation, and even intubation impossible. It is considered a frequent cause of unexpected difficult airway. Diagnosis cannot be made by standard airway physical examination. Once recognized, fiberoptic intubation is mandatory in subsequent surgeries.


Resumen Presentamos el caso de una vía aérea difícil imprevista debido a hipertrofia de la amígdala lingual no conocida. Mujer de 54 años, hipertensa, que ingresa para resección de masa mediastínica bajo anestesia general. Tras la inducción, la ventilación mediante mascarilla facial resultó imposible. Se coloca mascarilla laríngea (ML) y se consigue ventilación de forma subóptima. Se intenta intubación guiada por fibroscopia a su través, pero se objetiva masa protruyente que impide la progresión del tubo. Finalmente se intuba mediante introductor Frova. Tras finalizar la cirugía, la paciente se traslada intubada a la Unidad de Reanimación Postanestésica (URPA). Se realiza evaluación por otorrinolaringología (ORL), que concluye que la masa corresponde a una amígdala lingual hipertrófica. La hipertrofia de la amígdala lingual puede complicar la anestesia, dificultando la ventilación e intubación. Se considera una causa frecuente de vía aérea difícil imprevista. El diagnóstico no puede realizarse mediante exploración anestésica estándar. Una vez conocida, las intubaciones siguientes deben ser guiadas por fibroscopia.

ABSTRACT

Objetivo: Describir el uso irracional de antibióticos en base a criterios de McIsaac (criterios de Centor modificados por McIsaac), en una unidad de salud de primer nivel de atención. Métodos: Se realizó un estudio descriptivo transversal con los registros de pacientes de 3 a 19 años atendidos en el servicio de emergencia (246), con los diagnósticos de faringitis aguda, amigdalitis aguda, e infecciones respiratorias superiores agudas de múltiples sitios y sin especificar. Se estableció como prescripción inadecuada si el facultativo indicó antibióticos con un puntaje menor o igual a 1 sobre 5 puntos o si no prescribió antibióticos con puntaje mayor o 4 sobre 5 puntos. Resultados: Se estimó 24,29% de uso inadecuado de antibióticos de los registros de emergencia. Se prescribió antibióticos en 160 pacientes, de los cuales se encontró que, amoxicilina fue el más utilizado (61,87%); seguido de benzilpenicilina benzatina (28,12%) y en tercer lugar macrólidos (8,12%). Conclusión: En la unidad de primer nivel analizada se encontró que el uso inadecuado de antibióticos es superior a la prevalecía estimada de faringoamigdalitis estreptocócica para el grupo de edad estudiado. Por esto, es imperativo que se tomen las medidas necesarias a nivel institucional y comunitario para lograr su reducción y evitar las complicaciones que se derivan de esta.


Objetivo: Descrever o uso irracional de antibióticos com base nos critérios de McIsaac (critérios de Centor modificados por McIsaac), em uma unidade de saúde de primeiro nível de atenção. Métodos: Foi realizado um estudo descritivo transversal com os prontuários de pacientes de 3 a 19 anos atendidos no serviço de emergência (246), com diagnóstico de faringite aguda, amigdalite aguda, e infecções respiratórias superiores agudas de múltiplos locais e sem especificação. Estabeleceu-se como uma prescrição inadequada se o médico indicou antibióticos com um escore menor ou igual a 1 de 5 pontos ou se ele não prescreveu antibióticos com um escore maior ou igual a 4 de 5 pontos. Resultados: O uso inadequado de antibióticos foi estimado em 24,29% dos prontuários de emergência. Antibióticos foram prescritos em 160 pacientes, dos quais constatou-se que a amoxicilina foi a mais utilizada (61,87%); em segundo, a penicilina benzatina (28,12%); e, em terceiro lugar, os macrolídeos (8,12%). Conclusão: Na unidade de primeiro nível analisada foi encontrado que o uso de antibióticos é superior à prevalência de faringite estreptocócica estimada para a faixa etária estudada. Então, é imperativo que a nível institucional e comunitário sejam tomadas as medidas necessárias para sua redução e evitar as complicações resultantes.


Objective: To describe the irrational use of antibiotics based on McIsaac criteria (Centor criteria modified by McIsaac), in a primary care facility. Methods: A cross-sectional descriptive study was conducted with the medical record of patients from 3 to 19 years old, treated in the emergency department (246), with the diagnoses of acute pharyngitis, acute tonsillitis, and acute upper respiratory infections from multiple sites and not specified. It was established as an inappropriate prescription if the physician indicated antibiotics with a score less than or equal to 1 out of 5 points or if he did not prescribe antibiotics with a score greater than or equal to 4 out of 5 points. Results: Inadequate use of antibiotics was found in 24.29% of emergency records. Antibiotics were prescribed in 160 patients, of which, amoxicillin was the most used (61.87%); followed by benzathine penicillin (28.12%) and in third place macrolides (8.12%). Conclusion: In the first level unit analyzed, it was found that the inappropriate use of antibiotics is superior to the estimated prevalence of streptococcal pharyngitis for the age group studied. Therefore, it is imperative that the necessary measures are taken at the institutional and community level to achieve its reduction and avoid the complications that result from it.

ABSTRACT

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.

ABSTRACT

Fundamento: la adenoamigdalitis crónica en la infancia es una enfermedad frecuente en Cuba y ocupa el tercer lugar en la morbilidad quirúrgica en la especialidad de otorrinolaringología pediátrica. Objetivos: describir el comportamiento clínico-epidemiológico de la adenoamigdalitis crónica infantil. Métodos: se realizó un estudio descriptivo, prospectivo y transversal con un muestreo no probabilístico a 191 niños con adenoamigdalitis crónica, en un universo de 1 050 niños con enfermedades otorrinolaringológicas que asistieron al Hospital Pediátrico Universitario de Centro Habana entre septiembre de 2009 y julio de 2011. Para el procesamiento de datos se realizó una encuesta de factores de riesgo de padecer la enfermedad. Se efectuaron procesamientos estadísticos tales como: media, riesgo relativo porcentual y tablas de frecuencia por medio del software Excel. Resultados: la mayor morbilidad fue en varones de dos a cuatro años. La enfermedad se caracterizó por episodios de amigdalitis recurrente con obstrucción nasal y rinitis. Los factores de riesgo modificables más frecuentes fueron: ausencia o destete precoz, exposición involuntaria al humo del cigarro y la asistencia al círculo infantil. Los antecedentes personales y familiares más frecuentes fueron: alergia respiratoria o asma bronquial. Conclusiones: la enfermedad es de origen multifactorial y disminuye su morbilidad a partir de los seis años de edad.


Background: chronic adenotonsillitis in childhood is a very frequent disease in Cuba, and it occupies the third place in the surgical morbidity in the specialty of Pediatric Otorhinolaryngology. Objective: to describe the clinical-epidemiological behavior of chronic adenotonsillitis in childhood. Methods: a descriptive, prospective and cross-sectional study was conducted with a non-probabilistic sampling to 191 children with chronic adenotonsillitis in a universe of 1 050 children with otorhinolaryngological diseases treated in the Pediatric Hospital of Centro Habana, Cuba, from September 2009 to July 2011. Data processing was carried out using statistic tools such as: mean age, percentage relative risk and frequency tables by means of Excel software. Results: the biggest morbidity was in males from two to four years. The disease was characterized by episodes of recurrent tonsillitis with nasal obstruction and rhinitis. The most frequent modifiable risk factors were: absence or early suspension of maternal nursing, involuntary exposure to smoke cigar and the attendance to kindergarten. The most common personal and family antecedents were: respiratory allergy or bronchial asthma. Conclusions: this disease has a multifactorial origin, and it decreases its morbidity from the six years.

ABSTRACT

Arcanobacterium haemolyticum was isolated from the blood cultures of a previously healthy 37-year-old man who met all the criteria of Lemierre syndrome, including a primary oropharyngeal infection, evidence of thrombophlebitis of the internal jugular vein, and metastatic infections. To the best of our knowledge, this is the first case of Lemierre syndrome caused by A. haemolyticum in Korea and shows that A. haemolyticum alone can cause Lemierre syndrome.

ABSTRACT

OBJETIVOS: A faringoamigdalite aguda é uma das doenças mais freqüentes na prática pediátrica, sendo o estreptococo beta-hemolítico do grupo A (EBHGA) o agente etiológico bacteriano mais comum. O seu diagnóstico e tratamento adequados são importantes principalmente para a prevenção de seqüelas não-supurativas. Testes rápidos de detecção de antígenos do estreptococo do grupo A são uma ferramenta útil no diagnóstico das faringoamigdalites estreptocócicas, pela rapidez dos resultados, acurácia e baixo custo; no entanto, são pouco utilizados em nosso meio e pouco estudados em nosso país. O objetivo deste estudo foi avaliar a acurácia de um kit de teste rápido de detecção de antígeno do EBHGA comparado à cultura de suabe de orofaringe. MÉTODOS: Foram selecionadas crianças de 1 a 18 anos com diagnóstico clínico de faringoamigdalite aguda em serviços públicos de urgência e clínica privada de Belo Horizonte (MG), sendo excluídas as que haviam utilizado antibióticos até 30 dias antes da consulta. A amostra final incluiu 229 pacientes, que foram submetidos a coleta de dois suabes de orofaringe, um para o teste rápido para EBHGA e o outro enviado para cultura. RESULTADOS: Encontrou-se sensibilidade de 90,7 por cento, especificidade de 89,1 por cento, valor preditivo positivo de 72,1 por cento, valor preditivo negativo de 96,9 por cento e razão de verossimilhança positiva de 9,0 para o teste rápido utilizado comparado à cultura. CONCLUSÃO: O teste rápido utilizado apresentou boa correlação com a cultura, sendo, portanto, de grande utilidade na prática clínica para detecção do EBHGA.


OBJECTIVES: Acute pharyngitis is one of the most common diseases in pediatric practice, and the most common bacterial etiology is group A beta-hemolytic streptococcus (GABHS). Correct diagnosis and treatment are primarily of importance to the prevention of non-suppurative sequelae. Rapid tests for detecting the antigen of group A streptococcus are a useful tool for the diagnosis of streptococcal pharyngotonsillitis, due to the speed of results, accuracy and low cost; however, in our country they are little used and have been little studied. The objective of this study was to evaluate the accuracy of a GABHS rapid antigen detection test kit, in comparison with oropharynx swab culture. METHODS: Children aged 1 to 18 years with clinical diagnoses of acute pharyngitis were chosen at public emergency and private clinical services in Belo Horizonte, Minas Gerais, Brazil, with children being excluded if they had taken antibiotics within 30 days of their consultation. The final sample consisted of 229 patients, each of whom had two oropharynx swabs taken, one for rapid GABHS testing and the other to be sent for culture. RESULTS: We observed sensitivity of 90.7 percent, specificity of 89.1 percent, a positive predictive value of 72.1 percent, a negative predictive value of 96.9 percent and a positive likelihood ratio of 9.0 for the rapid test used here, compared with culture. CONCLUSIONS: The rapid test studied exhibited a good correlation with culture and is, therefore, of great use in clinical practice for detection of GABHS.
