Tuberculosis pulmonar y laríngea: una forma poco frecuente de presentación en la edad pediátrica / Pulmonary and laryngeal tuberculosis: a rare presentation in pediatrics / Tuberculose pulmonar e laríngica: uma apresentação pouco frequente na idade pediátrica

Introducción: la tuberculosis (TB) es una enfermedad infectocontagiosa granulomatosa crónica, producida por Mycobacterium tuberculosis. En Uruguay se ha notificado un aumento en el número de casos, con una incidencia reportada en 2017 de 28,6/100.000 habitantes, siendo de 6,67/100.000 en menores de 15 años. La tuberculosis laríngea es una forma poco frecuente y evolucionada de tuberculosis, que suele manifestarse con disfonía crónica. Su diagnóstico requiere un alto índice de sospecha. Objetivo: describir un caso clínico de presentación poco frecuente en la edad pediátrica. Caso clínico: adolescente de 13 años, sana, vacunas vigentes, con antecedentes de conductas sexuales activas y papilomatosis laríngea diagnosticada por laringoscopía directa como causa de disfonía crónica. Consulta en emergencia por dolor abdominal, constatándose al examen clínico adelgazamiento asociado a síntomas respiratorios y síndrome tóxico bacilar asociado a disfonía crónica de cuatro meses de evolución, por lo cual se plantea tuberculosis laríngea e ingresa para estudio. Niega contacto de tuberculosis. En la radiografía de tórax se constata lesión cavernosa en vértice pulmonar izquierdo. Las baciloscopías de esputo fueron positivas (directo y cultivo) confirmando el planteo de TB pulmonar y laríngea. Se realizó tratamiento antituberculoso supervisado con excelente evolución posterior. Conclusiones: la tuberculosis es una enfermedad reemergente en nuestro país, que requiere un alto índice de sospecha. Su diagnóstico sigue siendo un desafío para los pediatras ya que la confirmación diagnóstica no siempre es posible. En este caso clínico la sospecha clínica frente a una disfonía crónica asociada a síntomas respiratorios fue fundamental para establecer el diagnóstico, a pesar de no contar con nexo epidemiológico.

Introduction: tuberculosis (TB) is an infectious, chronic granulomatous disease caused by Mycobacterium tuberculosis. An increase in the number of cases has been reported in Uruguay, with an incidence reported in 2017 of 28.6/100,000 inhabitants, being 6.67/100,000 in children under 15 years of age. Laryngeal tuberculosis is a rare and evolved form of tuberculosis, which usually shows chronic dysphonia, which requires high levels of suspicion. Objective: to describe a clinical case with a rare presentation in pediatric age. Clinical case: 13-year-old female adolescent, healthy, fully vaccinated, with a history of active sexual behaviors and laryngeal papillomatosis diagnosed by direct laryngoscopy as a cause of chronic dysphonia. The emergency consultation was caused by abdominal pain, confirming the clinical examination weight loss associated with respiratory symptoms and bacillary toxic syndrome associated with chronic dysphonia of four months of evolution, for which laryngeal tuberculosis was considered and she was admitted for screening. She denies having been in contact with tuberculosis. The chest X-ray revealed a cavernous lesion in the left pulmonary apex and sputum smears were positive (direct and culture), confirming the suggestion of pulmonary and laryngeal TB. Supervised anti-tuberculosis treatment was performed with excellent subsequent evolution. Conclusions: tuberculosis is a re-emerging disease in our country, which requires a high level of suspicion. Its diagnosis remains a challenge for pediatricians since diagnostic confirmation is not always possible. In this clinical case, clinical suspicion of chronic dysphonia associated with respiratory symptoms were key factors to establish the diagnosis, despite not having a clear epidemiological link.

Introdução: a tuberculose (TB) é uma doença infecciosa granulomatosa crônica causada pelo Mycobacterium tuberculosis. No Uruguai, houve aumento do número de casos notificados, com uma incidência notificada em 2017 de 28,6/100.000 habitantes, sendo 6,67/100.000 casos de menores de 15 anos. A tuberculose laríngea é uma forma rara e evoluída de tuberculose, que geralmente se manifesta com disfonia crônica, exigindo alto índice de suspeita. Objetivo: descrever um caso clínico de apresentação pouco frequente em idade pediátrica. Caso clínico: menina adolescente de 13 anos, saudável, totalmente vacinada, com história de comportamentos sexuais ativos e papilomatose laríngea diagnosticada por laringoscopia direta como causa de disfonia crônica. Consulta de urgência por dor abdominal, comprovando emagrecimento associado a sintomas respiratórios e síndrome bacilar tóxica associada a disfonia crônica de quatro meses de evolução, para a qual foi considerada tuberculose laríngea e a paciente foi internada para estudo. Ele nega contato com tuberculose. A radiografia de tórax revelou lesão cavernosa em ápice pulmonar esquerdo e as baciloscopias de escarro foram positivas (direta e cultura) confirmando a sugestão de TB pulmonar e laríngea. O tratamento antituberculose supervisionado foi realizado com excelente evolução subsequente. Conclusões: a tuberculose é uma doença reemergente em Uruguai e requer alto índice de suspeita. Seu diagnóstico permanece um desafio para o pediatra, pois a confirmação diagnóstica nem sempre é possível. Neste caso clínico, a suspeita clínica de disfonia crônica associada a sintomas respiratórios foi fundamental para o estabelecimento do diagnóstico, apesar de não ter vínculo epidemiológico.

Tuberculosis laríngea secundaria a foco pulmonar primario inadvertido: caso clínico / Laryngeal tuberculosis secondary to an inadvertent primary pulmonary focus: clinical case

Introducción: La tuberculosis laríngea es una entidad sumamente rara en países del primer mundo, sin embargo, en nuestro medio no es extraño, como país latinoamericano, sospechar esta patología como una de las causas de disfonía y lesiones granulomatosas en la actualidad. La tuberculosis laríngea debe considerarse dentro de las patologías en pacientes con disfonía de larga evolución que no responden al tratamiento común, esta entidad puede ser confundida con neoplasias. Reporte de caso: Se presenta el caso de una mujer en la cuarta década de la vida con disfonía crónica de 6 meses de evolución, que fue remitida para laringoscopia. Se localizaron neoformaciones granulomatosas acompañadas de edema en ambas cuerdas vocales, sometidas a biopsia, con resultados con la tinción de hematoxilina-eosina de células gigantes multinucleadas de Langhans y la tinción Zielh-Nielsen fue positiva para bacilo alcohol ácido resistente. La radiografía de tórax mostró lesiones reticulonodulares sugestivas de tuberculosis pulmonar. Conclusión: Un alto nivel de sospecha y un diagnóstico temprano pueden limitar las complicaciones y facilitar un manejo oportuno de estos casos. Es necesario sospechar de tuberculosis laríngea en pacientes que presentan disfonía crónica, especialmente cuando se asocia con síntomas constitucionales, aunque no siempre los presentan, por otro lado, en algunos casos, no existe asociación con inmunodeficiencia.

Introduction: Laryngeal tuberculosis is an extremely rare entity in first world countries, however, it is not strange in our environment as a Latin American country to suspect this pathology as one of the causes of dysphonia and granulomatous lesions today. Laryngeal tuberculosis should be considered within the pathologies in patients with long-standing dysphonia that do not respond to common treatment, this entity can be confused with neoplasms. Case report: We present the case of a female in the fourth decade of life with chronic dysphonia of six months of evolution, who was referred for laryngoscopy, granulomatous neoformations accompanied by edema in both vocal cords were located, subjected to biopsy with results with hematoxylin staining. Langhans multinucleated giant cell eosin and Zielh-Nielsen staining were positive for acid-fast bacillus. Chest X-ray showed reticule-nodular lesions suggestive of pulmonary tuberculosis. Conclusion: A high level of suspicion and an early diagnosis can limit complications and facilitate timely management of these cases. It is necessary to suspect laryngeal tuberculosis in patients with chronic dysphonia, especially when associated with constitutional symptoms, although they do not always present them; on the other hand, in some cases, there is no association with immunodeficiency

TBC laríngea: una localización poco común de la tuberculosis / Laryngeal tuberculosis: an unusual location for tuberculosis

Según datos de la OMS, la tuberculosis es una de las diez primeras causas de muerte en el mundo y es la primera causa de muerte por un agente infeccioso único. La incidencia de la tuberculosis ha disminuido por término medio un 1,5% anual desde el año 2000 sin embargo el impacto de la pandemia por el SARS-CoV-2 pudiera retardar el diagnóstico y tratamiento de nuevos casos de TB. Se presenta el caso de un paciente masculino de 26 años de edad quien consulta por presentar fiebre de predominio vespertino, pérdida de peso y disfonía de 6 meses de evolución. Los BK y cultivos de esputo seriados resultaron negativos. Es referido al Servicio de Otorrinolaringología y Cirugía Facial del Hospital Universitario Dr. Luis Gómez López donde se realiza una nasofibrolaringoscopía evidenciándose epiglotis con superficie de aspecto irregular que se extiende hasta aritenoides y zona interaritenoidea y bandas ventriculares edematizadas que no permiten visualizar repliegues vocales. Se realiza microcirugía laríngea para toma de biopsia reportando el estudio histopatológico proliferación de vasos neoformados, espacios intervasculares ocupados por macrófagos y linfocitos, presencia de múltiples lesiones nodulares formadas por macrófagos epiteloides rodeados por un halo de linfocitos y numerosas células gigantes de Langerhans. Se realiza el diagnóstico de tuberculosis laríngea y se inicia tratamiento antituberculoso(AU)

According to the WHO, tuberculosis represents one of the top ten causes of death worldwide and is the number one cause of death from a single infectious agent. The incidence of tuberculosis has decreased an average of 1.5% annually since the year 2000, however the impact of the SARS-CoV-2 pandemic could delay the diagnosis and treatment of new cases of TB. We report the case of a 26-year-old male who consulted for fever, weight loss and dysphonia with a duration of 6 months. BK and sputum cultures were negative for M. tuberculosis. The patient is referred to the Otorhinolaryngology and Facial Surgery Clinic of the Dr. Luis Gomez Lopez University Hospital where a nasofibrolaryngoscopy is performed showing an epiglottis with an irregular surface that extends to the arytenoids and interarytenoid zone and edematous ventricular bands that do not allow visualization of vocal folds. Laryngeal microsurgery is performed to obtain a biopsy sample. Histopathology reveals proliferation of newly formed vessels, intervascular spaces occupied by macrophages and lymphocytes, presence of multiple nodular lesions formed by epithelloid macrophages surrounded by a halo of lymphocytes and numerous giant Langerhans cells. Diagnosis of laryngeal tuberculosis is made and antituberculous treatment is initiated(AU)

Tuberculous Laryngitis mimicking as Fungal Laryngitis: A case report

@#Tuberculous laryngitis was considered common during pre-antibiotic area but after the effective antitubercular medication, the incidence of laryngeal tuberculosis had decreased to less than one percent2. Clinical presentation is mostly unclear but usually presents with odynophagia, cough, hoarseness of voice and frequently confused with other diseases, more importantly fungal laryngitis. This is a case of a diagnostic dilemma of an immunocompetent 55-year-old male presenting with odynophagia, dysphagia and hoarseness of voice that was initially managed as a case of fungal laryngitis due to history of prolonged use of dexamethasone and findings of leukoplakia in laryngoscopy. Despite adequate time for treatment, no significant improvement was noted. Acid fast bacilli microscopy tested negative. A previous history of pulmonary tuberculosis treatment and chest radiographs revealing fibrosis on both upper lungs puts tuberculous laryngitis as one of the differentials. Sputum GeneXpert/RIF taken and tested positive, hence lead to the diagnosis of tuberculous laryngitis. Guideline-based quadruple anti-tubercular therapy started and had showed a positive response. Laryngeal tuberculosis (LTB) requires a high index of suspicion since it mimics various laryngeal diseases such as fungal laryngitis or malignancy. Clinicians should always be aware of the atypical clinical features of laryngeal tuberculosis and the possibility of primary laryngeal tuberculosis, for early diagnosis and prompt treatment, thus preventing morbid complications. A positive mycobacterial culture along with a typical histopathological appearance remain the cornerstone of diagnosis, but sputum AFB in microscopy and GeneXpert/RIF must not be ignored as these can be cost-effective diagnostic alternatives.

Tuberculosis laríngea en una gestante en un centro de salud / Laryngeal tuberculosis in a pregnant in a health center

La tuberculosis (TBC) es la enfermedad con mortalidad global más alta producida por un único agente infeccioso. La TBC durante la gestación es crítica incluso con tratamiento, que pueden tener reactivaciones y efectos adversos en el feto. Se describe un caso de TBC laríngea de un apaciente con embarazo gemelar a quien se le dio tratamiento según esquema del programa del Ministerio de Salud dando un excelente resultado materno-perinatal. (AU)

Tuberculosis (TB) is the disease with the highest overall mortality caused by a single infectious agent. TB during pregnancy is critical even with treatment, which can have reactivations and adverse effects on the fetus. A case of laryngeal TB is described from a patient with a twin pregnancy who was treated according to the scheme of the Ministry of Health program giving an excellent maternal-perinatal result. (AU)

Relato de Caso: paralisia unilateral de prega vocal por tuberculose mediastinal / Case report: unilateral vocal fold paralysis by mediastinal tuberculosis

Introdução: A tuberculose (TB) acomete especialmente os pulmões, no entanto, também se tem conhecimento das formas extrapulmonares. Dentre essas, buscamos relatar um caso raro de TB mediastinal localizada em trajeto de nervo laríngeo recorrente (NLR), a qual se manifestou com paralisia de prega vocal (PPV). Relato de Caso: Paciente masculino, 58 anos, apresentando quadro de disfonia. Histórico de exérese de testículo esquerdo e anatomopatológico evidenciando orquiepididimite crônica granulomatosa sugestiva de etiologia tuberculosa. Ex-tabagista e ex-etilista. Realizou, há 15 anos, um tratamento por 6 meses para TB pulmonar. Contactante de paciente bacilífero há três anos. A videolaringoscopia identificou PPV esquerda paramediana. A tomografia computadorizada (TC) de pescoço evidenciou linfonodos calcificados no mediastino superior, fossas supraclaviculares e espessamento de corda vocal à direita. A TC de Tórax apresentou conglomerados sequelares linfonodais calcificados no mediastino e sequela de processo granulomatoso crônico tipo TB em ápices pulmonares. Sorologia de HIV não reagente. Baciloscopia negativa, com amostra insuficiente. Cultura de escarro negativa. Discussão: A PPV esquerda encontrada na videolaringoscopia e TC de pescoço e os achados de TB mediastinal indicaram acometimento do NLR esquerdo pelo processo granulomatoso em seu trajeto, sendo esse, uma reativação de TB ganglionar mediastinal. Fora realizado esquema básico de tratamento para TB, com posterior resolução do quadro de disfonia. Embora a TB torácica seja uma condição comum, a rouquidão devido à PPV é uma complicação raramente associada. Conclusão: Salientamos a importância de estender a investigação ao mediastino na vigência de PPV unilateral, uma vez que a disfunção do NLR pode justificar o quadro.

Introduction: tuberculosis (TB) affects most commonly the lungs; nevertheless, extrapulmonary forms are also known. With that in mind, we intend to report a rare case of mediastinal TB located on the path of the recurrent laryngeal nerve (RLN), manifesting itself with vocal fold paralysis (VFP). Case report: male patient, 58 years old, presenting dysphonia. History of exeresis of the left testicle and anatomopathological showing chronic granulomatous orchiepididimitis, suggestive of tuberculous etiology. Former smoker, ex-alcoholic. Previous treatment for six months due to pulmonary TB, 15 years ago. Bacilli patient contactant for three years. Videolaryngoscopy identified paramedian left VFP. Computed tomography (CT) of the neck showed calcified lymph nodes in the upper mediastinum, supraclavicular fossa, and thickening on the right vocal cord. Chest CT showed calcified lymph node sequels in the mediastinal and Chronic Granulomatous TB-type sequel in pulmonary apices. Non-reactive HIV serology. Negative baciloscopy, insufficient sample. Negative sputum culture. Discussion: the finding of left VFP in videolaryngoscopy and neck CT, associated with the findings of mediastinal TB, indicated that the left RLN's involvement occurred due to the granulomatous process in its path, meaning a reactivation of mediastinal ganglionic TB. A simple treatment schedule for TB had been conducted, with subsequent resolution of the dysphonia. Even though thoracic TB is a common condition, hoarseness due to VFP is a rarely associated complication. Conclusion: we stress the importance of extending the investigation to the mediastinum in case of unilateral VFP since a dysfunction of the RLN is a possible justification of the case.

Tuberculosis en otorrinolaringología. Reporte de 3 casos / Tuberculosis in otolaryngology. Report of 3 cases / Tuberculose em otorrinolaringología. Relatório de 3 casos

La tuberculosis extrapulmonar suele ser una presentación poco frecuente. Aunque la vía respiratoria alta es la vía de entrada del Mycobacterium tuberculosis, su afectación es rara (menos del 2%), siendo la localización ótica, laríngea y nasofaríngea de carácter excepcional, pudiéndose presentar tanto de forma primaria como secundaria a una lesión pulmonar. Se describen tres formas de presentación de tuberculosis extrapulmonar, resaltando la importancia de su sospecha clínica; fundamental para el diagnóstico. Se reporta un caso de tuberculosis laríngea como presentación primaria; un caso de tuberculosis faríngea como presentación secundaria y un caso de presentación ótica en un paciente inmunocomprometido. Debido al aumento en los últimos años de esta enfermedad es necesario tenerla presente como diagnóstico diferencial. Se destacan las dificultades en su detección, ya que no existen características exclusivas de la tuberculosis. La importancia del diagnóstico precoz radica en que es una enfermedad con buena evolución si es tratada oportunamente.

Extrapulmonary tuberculosis is usually an uncommon presentation. Although the upper respiratory tract is the entry route of the Mycobacterium tuberculosis, its involvement is rare (less than 2%), being the otic, laryngeal and nasopharyngeal localization exceptional, being able to present both primary and secondary to a lung injury. Three forms of presentation of extrapulmonary tuberculosis are described highlighting the importance of their clinical suspicion; fundamental for the diagnosis. A case of laryngeal tuberculosis is reported as primary presentation; a case of pharyngeal tuberculosis as a secondary presentation and a case of otic presentation in an immunocompromised patient. Due to the increase in recent years of this disease it is necessary to keep it in mind as a differential diagnosis. The difficulties in its detection are highlighted, since there are no exclusive characteristics of tuberculosis. The importance of early diagnosis lies in the fact that it is a disease with good evolution if it is treated opportunely.

A tuberculose extrapulmonar é geralmente uma apresentação incomum. Embora a via aérea superior é o Mycobacterium tuberculosis porta de entrada, o seu envolvimento é rara (menos do que 2%), a localização ótica, da laringe e da nasofaringe excepcional, sendo possível que tanto na forma primária como secundária à lesão do pulmão. Três formas de apresentação da tuberculose extrapulmonar são descritas, destacando a importância de sua suspeita clínica; fundamental para o diagnóstico. Um caso de tuberculose laríngea é relatado como apresentação primária; um caso de tuberculose faríngea como apresentação secundária e um caso de apresentação ótica em paciente imunocomprometido. Devido ao aumento nos últimos anos desta doença é necessário ter isto em mente como um diagnóstico diferencial. As dificuldades em sua detecção são destacadas, uma vez que não existem características exclusivas da tuberculose. A importância do diagnóstico precoce reside no fato de ser uma doença com boa evolução se tratada oportunamente.

Tuberculosis primaria de laringe simulando un carcinoma laríngeo. Reporte de caso / Primary tuberculosis of larynx simulating a laryngeal carcinoma. Report of case

Fundamento: La tuberculosis laríngea es una enfermedad infrecuente, sobre todo cuando se presenta de forma localizada. Objetivo: Exponer la localización laríngea primaria de la tuberculosis que simuló un carcinoma laríngeo. Caso clínico: Paciente de 40 años de edad, fumador de dos cajetillas de cigarro diarias por más de veinte años. Consultó por disfonía persistente de aumento gradual, odinofagia, tos pertinaz y pérdida de 10 Kg de peso en dos meses. El examen físico general fue normal. Se visualizó la cuerda vocal derecha hemiparética de aspecto tumoral en los dos tercios anteriores. En el estudio analítico se encontraron exámenes patológicos como la prueba de la tuberculina, Velocidad de sedimentación globular (VSG) de 95 mm/1ra hora y lactato deshidrogenasa (LDH) de 860 UI/L, fueron totalmente negativos los exámenes imaginológicos. Resultados: El estudio histológico luego de tomar biopsia, confirmó la existencia de tuberculosis laríngea primaria; no existía evidencia clínica ni imaginológica de afectación de otros órganos. Conclusiones: Se presentó un paciente con síntomas laríngeos y constitucionales. La tuberculosis primaria de laringe es una enfermedad rara, infrecuente de la que existen escasos reportes en la literatura médica internacional; teniendo en cuenta además que la tuberculosis inicialmente afecta el pulmón y luego se disemina.

Background: The laryngeal tuberculosis is an uncommon illness, mainly when it is presented in a located way. Objective: To expose the primary laryngeal localization of the tuberculosis that simulated a laryngeal carcinoma. Clinical case: Patient of 40 years old, smoker of two daily cigarette packs for more than twenty years. He was consulted for persistent dysphonia of gradual increase, odynophagia, tenacious cough and loss of 10 Kg of weight in two months. The general physical exam was normal. The right hemiparetic vocal cord of tumor aspect was visualized in the two previous thirds. In the analytic study, pathological exams were found as the tuberculin test, Speed of globular sedimentation (VSG) of 95 mm/1st hour and lactate dehydrogenase (LDH) of 860 UI/L, the x- ray exams were completely negative. Results: The histological study after taking biopsy, confirmed the existence of primary laryngeal tuberculosis; there was no clinical or imagiologic evidence of involvement of other organs. Conclusions: A patient was presented with laryngeal and constitutional symptoms. The primary tuberculosis of larynx is a strange illness, uncommon of which there are scarce reports in the international medical literature; also keeping in mind that the tuberculosis initially affects the lung and then it is disseminated.

Diagnóstico patológico y molecular de un caso de tuberculosis laríngea primaria en un médico / Pathological and molecular diagnosis in a case of primary laryngeal tuberculosis in a physician

La tuberculosis laríngea primaria es una enfermedad rara con una amplia gama de manifestaciones clínicas. Se reporta el caso de un médico otorrinolaringólogo con diabetes de tipo II y con diagnóstico de tuberculosis laríngea primaria. El diagnóstico de cáncer de cuerda vocal se había considerado en otra institución, y al ingreso el paciente sólo presentaba disfonía de seis meses de evolución. En el estudio histopatológico se encontraron granulomas, células gigantes multinucleadas, fibrosis y necrosis, y en la tinción de Ziehl-Neelsen, bacilos ácido-alcohol resistentes. El cultivo del tejido de cuerda vocal para micobacterias y la PCR-IS6110 fueron positivos. La cepa de Mycobacterium tuberculosis demostró sensibilidad a todos los medicamentos de primera línea. Se inició tratamiento según la estrategia DOTS ( Directly Observed Treatment, Short -course ). Se discute la presentación clínica, los diagnósticos diferenciales, el abordaje diagnóstico y los factores de riesgo asociados y se hace una breve revisión de la literatura.

Primary laryngeal tuberculosis is a rare disease with a wide variety of clinical manifestations. We report the case of an ear-nose and throat diabetic physician with primary laryngeal tuberculosis. The diagnosis of laryngeal cancer had been considered before in another institution, and at the patient´s admission, he only presented dysphonia with a six-month evolution. The vocal cord histological examination showed granulomas, giant cells, fibrosis and necrosis, and the Ziehl-Neelsen staining showed acid-alcohol resistant bacilli. The culture from vocal cord tissue was positive for mycobacteria, and IS 6110 -PCR was positive too. The Mycobacterium tuberculosis strain was sensitive to first line drugs. Treatment using directly observed therapy short-course (DOTS) was initiated. Clinical presentation, differential diagnosis, diagnostic workup, associated risk factors and a brief literature revision are discussed in this article.

Tuberculosis pulmonar, esofágica y laríngea / Pulmonary, esophageal and laryngeal tuberculosis

Resumen La tuberculosis es una de las enfermedades que más ha impactado en la sociedad a nivel mundial siendo influenciada por la pandemia del VIH, los patrones migratorios y el uso de la medicación antituberculosa. La forma extrapulmonar es rara siendo más característica en los pacientes inmunocomprometidos, cuyas manifestaciones clínicas son inespecíficas, por lo que constituye un reto diagnósticopara los clínicos, en la mayoría de los casos retardando su detección y tratamiento. Se presenta el caso clínico de un paciente aparentemente inmunocompetente que consulta por cuadro de seis años de evolución de disfagia progresiva, pérdida de peso inexplicada, en quien se encontró compromiso por tuberculosis a nivel esofágico y laríngeo que explicaban los síntomas de ingreso, así como compromiso pulmonar sin clara sintomatología. Cuadro llamativo y de relevancia por su forma de presentación de alto riesgo de diseminación de la infección en un paciente sin inmunocompromiso. (Acta Med Colomb 2014; 39: 85-89).

Abstract Tuberculosis is one of the diseases that has more impacted the global society, being influenced by the HIV pandemic, migration patterns and the use of anti-TB drugs. Extrapulmonary tuberculosis is rare, being more characteristic in immunocompromised patients, whose clinical manifestations are nonspecific, thus constituting a diagnostic challenge for clinicians and in most cases delaying its detection and treatment. The case of a patient apparently immunocompetent consulting for a six years history of progressive dysphagia and unexplained weight loss, in whom involvement of esophagus and larynx by tuberculosis was found explaining the symptoms of admission, as well as the pulmonary involvement with no clear symptoms, is presented. It is a striking and relevant clinical picture by its presentation with high risk of dissemination of the infection in a patient without immunocompromise. (Acta Med Colomb 2014; 39: 85-89).

Intervenção fonoaudiológica precoce nos distúrbios vocais em pacientes com tuberculose laríngea / Early intervention speech therapy in in voice disorders in patients with laryngeal tuberculosis

INTRODUÇÃO: Embora possa ser tratada clinicamente com sucesso, a tuberculose laríngea (TBL) pode causar mudanças irreversíveis na qualidade da voz. Raros estudos relatam intervenções fonoaudiológicas para tratar a disfonia na TBL. OBJETIVO: Avaliar a qualidade vocal dos pacientes com TBL em atividade e os efeitos da intervenção fonoaudiológica precoce na reabilitação das funções vocais alteradas nesses indivíduos. MÉTODO: Esta dissertação é composta por dois artigos desenvolvidos com dados de pacientes com TBL atendidos no Instituto de Pesquisa Clínica Evandro Chagas, Fundação Oswaldo Cruz, no período de 2010 a 2013. No primeiro foram relatadas as alterações anatômicas e vocais de três pacientes com TBL ativa antes de iniciar o tratamento. No segundo artigo foi realizado um estudo longitudinal para avaliar o impacto da terapia fonoaudiológica na recuperação das alterações vocais diagnosticadas ao início do tratamento da TBL em 11 pacientes. As avaliações fonoaudiológicas iniciais e finais foram comparadas através dos testes de McNemar, T de Student, sinal de Wilcoxon, Friedman e do Chi quadrado, considerando-se significativos os valores de p<0,05. RESULTADOS: No primeiro artigo, entre os indivíduos avaliados, observou-se que os principais sítios afetados foram as pregas vocais, pregas ariepiglóticas, aritenóides e epiglote e os principais sintomas foram disfonia, disfagia e odinofagia. No segundo artigo, foram avaliados 11 pacientes com uma média de idade 56,55 anos (±18,31), 2 eram do sexo feminino e 9 do sexo masculino, 4 pacientes eram tabagistas e 7 etilistas. A TBL e tuberculose pulmonar estavam associadas em 9 indivíduos. Nestes, encontrou-se inicialmente 100 por cento de disfonia, 54,5 por cento de disfagia e 45,5 por cento de odinofagia...

INTRODUCTION: Although it can be treated medically with success, laryngeal tuberculosis (LT) can cause irreversible changes in voice quality. Few studies report speech therapy interventions to treat dysphonia in LT. OBJECTIVE: To evaluate the vocal quality of patients with LT in activity and the effects of early languageintervention in the rehabilitation of vocal functions altered in these individuals. METHOD: This dissertation consists of two papers developed with data from patients with TBL that were treated at Clinical Research Institute Evandro Chagas, Oswaldo Cruz Foundation, in the period 2010-2013. In the first anatomical changes andvocals from three patients with active LT were reported before starting treatment. In the second article, a longitudinal study was conducted to evaluate the impact of speech therapy in the recovery of vocal disorders diagnosed at initiation of treatmentof LT in 11 patients. The initial and final speech evaluations were compared using the McNemar test , Student t, Wilcoxon sign , Friedman and Chi square and p values < 5 percent were considered significant. RESULTS: In the first article the main sites affected were the vocal folds, aryepiglottic folds, arytenoids and epiglottis and the main symptoms were dysphonia, dysphagia and odynophagia. In the second article we evaluated 11 patients with a mean age of 56.55 years (± 18.31), 2 females and 9 males, 4 patients were smokers and drinkers 7. The LT were associated with pulmonary tuberculosis and 9. These patients initially find 100 percent of dysphonia, dysphagia 54.5 percent and 45.5 percent of odynophagia. The most affected sites were the larynx: vocal folds in 81.8 percent, 63.6 percent in vestibular folds, epiglottis in 36.4 percent, 27.3 percent arytenoids, aryepiglottic folds in 36.4 percent, and interarytenoid space 9.1 percent...

Primary mucosal tuberculosis of head and neck region: a clinicopathologic analysis of 47 cases / 中华病理学杂志

<p><b>OBJECTIVE</b>To study the clinicopathologic features, histologic diagnosis and differential diagnosis of primary mucosal tuberculosis (TB) in the head and neck region.</p><p><b>METHODS</b>Forty-seven cases of primary mucosal TB of the head and neck region were studied by hematoxylin-eosin and Ziehl-Neelsen stains. The clinical and pathologic features were analyzed with review of the literature.</p><p><b>RESULTS</b>The patients included 26 male and 21 female, with mean age 47.1 years (range 14-84 years). There were three sinonasal TB, 19 nasopharyngeal TB, two oropharyngeal TB, 18 laryngeal TB, four middle ear TB, one salivary gland TB and one laryngeal TB complicating laryngeal cancer. The initial symptoms were nasal obstruction, mucopurulent rhinorrhea, epistaxis, snoring, hoarseness, dysphagia, odynophagia, serous otitis, hearing loss, tinnitus, and otalgia. Physical examination result was variable, from an apparently normal mucosa, to an evident mass, or a mucosa with an adenotic or swollen appearance, ulcers, leukoplakic areas, and various combinations thereof. CT and MRI findings included diffuse thickening, a soft-tissue mass, calcification within the mass and bone destruction resembling malignancy. Histologic examination showed granulomas with a central necrotic focus surrounded by epithelioid histiocytes and multinucleated Langhan's giant cells. Acid-fast bacilli were difficult to demonstrate but found in 13/45 cases. Follow-up data were available in 42 patients.</p><p><b>CONCLUSIONS</b>Primary TB arising in the head and neck mucosa is rare. It may mimic or co-exist with other conditions. The characteristic histopathology is a granuloma with central caseous necrosis and Langhans'giant cells. Identification of acid-fast bacilli and bacteriologic culture confirm the diagnosis of mycobacterial disease.</p>

Perfil epidemiológico dos pacientes portadores de tuberculose extrapulmonar atendidos em hospital da rede pública no estado do Maranhão / Epidemiological profile of patients with extrapulmonary tuberculosis in a public hospital in state of Maranhão

JUSTIFICATIVA E OBJETIVOS: Embora conhecida desde a antiguidade, a tuberculose (TB) continua preocupando as autoridades sanitárias até os dias de hoje. O presente estudo teve como objetivo descrever o perfil clínico e epidemiológico dos pacientes diagnosticados com tuberculose extrapulmonar (TBEP) atendidos em hospital da rede pública de saúde no estado do Maranhão. MÉTODO: Trata-se de uma análise descritiva, com abordagem quantitativa. Foram analisados 133 prontuários de pacientes portadores de TBEP que receberam atendimento na unidade hospitalar referida no período de abril de 2007 a abril de 2009. RESULTADOS: Verificou-se predomínio do sexo masculino (61,4%), adultos jovens (51,8%) e com relação aos aspectos clínicos, apenas 14,3% dos pacientes apresentaram TBEP. A baciloscopia foi realizada em 86% dos pacientes; e destes apenas 9% apresentaram resultado positivo. A cultura foi empregada em 8,3%. Quanto à evolução 58,6% obtiveram cura, três foram a óbito (2,2%) e houve apenas três casos de abandono (2,2%) do Programa de Controle de Tuberculose (PCT) do Município. CONCLUSÃO: Este estudo possibilitou conhecer características da TBEP na população estudada, além de avaliar, indiretamente,o serviço de saúde dirigido ao controle da doença.

This study describes the clinical and epidemiological profile of extrapulmonary tuberculosis(ETB) cases assisted in a TB specialty public hospitallocated in São Luís, MA. METHOD: A descriptive analysis with a quantitative approach was made in order to support this study; 133 medical reports were analyzed and data from individual tuberculosis Investigation files and tuberculosis case registries were compiled, within the time span between April/2007 and April/2009. RESULTS: Disease occurred predominantly in males (61.4%),and in young adults (51.8%). As for the clinical presentation,only 14.3% of the total patients were diagnosed with extrapulmonary tuberculosis. Bacilloscopy was performed in 86% of these patients, within which only 9% had a positive result. Culture was performed in only 8.3% of patients. Among the patients treated by the Municipal Tuberculosis Control Program (PCT),58.6% were cured; 2.2% died and 2.2% (3 cases) abandoned treatment. CONCLUSION: This investigation permits an improved understanding of extrapulmonary tuberculosis characteristics in this particular setting and enables an indirect evaluation of the public healthcare system treatment of this disease.

Tuberculose laríngea: proposta de intervenção fonoaudiológica nas sequelas de voz após o tratamento farmacológico / Laryngeal tuberculosis: proposal of Speech-Language Pathology intervention in voice disorders following pharmacological treatment

A tuberculose é uma doença que esteve presente durante toda história. No século XIX o bacilo causador da doença foi descoberto e denominado bacilo de Koch. A tuberculose laríngea é uma das complicações da tuberculose pulmonar, e o sintoma mais comum é a rouquidão, decorrente ao processo cicatricial das lesões laríngeas. Sendo assim, o objetivo deste estudo foi verificar a efetividade da fonoterapia em um caso de disfonia pós-tratamento medicamentoso da tuberculose laríngea. A metodologia utilizada foi o estudo de caso do paciente J.O.B.S, 39 anos, gênero masculino, recepcionista de hotel, com jornada de oito diárias e ex-fumante, que trouxe como queixas principais rouquidão, cansaço e falta de ar durante a fala. Após as avaliações fonoaudiológica e otorrinolaringológica iniciaram-se as sessões de fonoterapia, com objetivo de diminuir a tensão à fonação, induzir o afastamento de pregas vestibulares, favorecer a mobilidade das pregas vocais, instaurar a respiração com apoio abdominal e melhorar a coordenação pneumofonoarticulatória. Após as 12 sessões previstas na metodologia desse estudo, diversos parâmetros vocais apresentaram melhoras, dentre eles a diminuição da tensão à fonação, respiração com apoio abdominal, melhoria da coordenação pneumofonoarticulatória, aumento da loudness e diminuição do ataque vocal brusco, que refletiram em uma emissão com menor esforço e mais aceita socialmente. A terapia fonoaudiológica, apesar das limitações decorrentes aos processos cicatriciais das lesões, mostrou-se importante no caso apresentado e o paciente ficou satisfeito com os resultados obtidos, os quais refletiram de forma positiva na comunicação oral e no convívio social do paciente.

Tuberculosis is a disease that has been present throughout history. In the XIX century the agent that causes the disease was discovered and named mycobacterium tuberculosis. Laryngeal tuberculosis is one of the possible complications from pulmonary tuberculosis, and the most common symptom is hoarseness, as a result of the healing process of ulcerative laryngeal lesions. The purpose of this study was to verify the effectiveness of speech-language therapy in a case of voice disorder following anti-tuberculosis drug treatment. The methodology used was the case study of the patient J.O.B.S, 39 years old, male, hotel receptionist with an eight-hour workday, former smoker, who had hoarseness, tiredness and dyspnea during speech as main complaints. Speech-language therapy sessions started after Speech-Language Pathology and otolaryngological evaluations, with the aims to reduce the laryngeal tension during phonation, induce supraglottic vocal fold separation, help the smooth movement of the vocal folds, install abdominal breathing, and improve pneumophonic coordination. After 12 sessions, several vocal parameters improved, including decrease of vocal tension during speech, use of abdominal breathing, improvement of pneumophonic coordination, loudness increase, and reduction of the abrupt vocal attack, which reflected in vocal emissions with less effort and more socially accepted. In spite of the limitations caused by the healing of the ulcerative lesions, speech-language therapy was important in this case study, and the patient was satisfied with the results obtained, which had positive influences on his oral communication and social life.

Secondary laryngeal tuberculosis at high altitudes of Tibet / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To improve the diagnostic and therapeutic efficiency for secondary laryngeal tuberculosis through an analysis on the clinical features of patients with this disease.@*METHOD@#A retrospective study was made among 49 cases with laryngeal tuberculosis treated in Tibetan General Hospital of Chinese PLA, and the clinical data were carefully analyzed to summarize the clinical experience of this disease.@*RESULT@#Of 49 patients, 24 cases had 1 year history, 11 cases had 1 to 3 years, 9 cases had 3 to 5 years, 5 cases had 5 years or more. Thirty-eight patients had the history of tuberculosis and 11 had none. Thirty-four patients had taken anti-tuberculosis drugs but none had standard therapy as demanded. All cases had mild general symptoms (mild fever, night sweats, weight loss, et al) and atypical local symptoms (hoarseness, sore throat). Therefore, 42 cases were misdiagnosed as non-specific chronic laryngitis, of which 15 cases got worse after oral administration or inhaling of steroid hormones. Seven persons were misdiagnosed as laryngeal cancer. All patients were confirmed pulmonary tuberculosis by X ray exam or CT scanning. Twelve cases had strong positive PPD tests and 2 cases were detected positive by sputum smear. All patients was treated by standard systematic and local chemical therapy against tuberculosis (inhaling of antituberculosis drugs for 1 to 2 months). All were cured but one died in a road accident, and none had recurrence after 1- to 9- year follow-up.@*CONCLUSION@#All of those the patients with long period hoarseness and sore throat should take chest CT scan or X-ray exam for the highest incidence of pulmonary tuberculosis at high altitudes. CT scanning is the prefer for its high resolution. Pathological biopsy and diagnostic therapy should be taken to make accurate diagnosis. Usually steroid hormones should not be recommended.

Tuberculosis en faringe y laringe: presentación de un caso / Tuberculosis in pharyn and larynx: case presentation

La tuberculosis, infección bacteriana crónica causada por el Mycobacterium tuberculosis, declarada por la OMS (1993) como emergencia epidemiológica, afecta mayoritariamente los pulmones, pero puede afectar a otros órganos (Tb. Extrapulmonar), entre estos a la laringe, constituyendo la más frecuente enfermedad granulomatosa a este nivel y considerada una localización rara (menos de 1 por ciento); por ello nuestro interés de presentar un caso de Tuberculosis en faringe y laringe, con el objetivo de resaltar lo infrecuente de esta ubicación, los problemas diagnósticos y la importancia del estudio histopatológico. Paciente de 49 años, femenina, consulta por Odinofagia, se encuentra tumor en faringe, se realiza biopsia y el diagnóstico fue: Sarcoidosis faríngea, no regresó a consulta. Meses después asiste por disfonía, se visualiza tumor en laringe, se realiza biopsia y el informe fue carcinoma de laringe; se negó a tratarse. Cuatro meses más tarde, ingresa en el Hospital Neumológico, por disnea, tos y disfonía, el diagnóstico fue tuberculosis pulmonar (Cod 9). Interconsultan con Otorrinolaringología el tratamiento del cáncer laríngeo. Decidimos nueva revisión de las biopsias, y se arribó a las conclusiones siguientes: "Tuberculosis miliar acorde con su cuadro clínico y hallazgos anatomo-patológicos: (faringitis y laringitis granulomatosa); no se corresponde ni con Sarcoidosis ni con carcinoma Epidermoide previamente reportado.".

Tuberculosis is a chronic bacterial disease caused by Mycobacterium tuberculosis, declared by WHO in 1993 as epidemilogical emergency warning, affecting mostly the lungs but it can also damage others organs (Extra lung Tb) such as the larynxbeing the most frequent granulomatous disease as this level and it considered as a rare location (less than 1 percent), that is why we are so interested in presenting this case report of larynx and pharynx disease, with the aspiration to highlight how few are the cases with this location, the diagnostic problems and the importance of a histopathologic analysis. 49 years, female patient came to the consultation because of odenaphagia. A pharyngeal tumour was diagnosed and a biopsy was undergone which revealed pharyngeal Sarcoidosis. The patient did not come back to the consultation until several months later due to diphonia. A tumour in the larynx is visualized and a biopsy is undergone again which shoved to the positive for laryngeal cancer; the patient refuses to be treated. Four months later the patient is admitted to the hospital in the Neumology hospital with a clinical picture of dyspnea, cough and dysphonic. The diagnosis was pulmonary tuberculosis. A consult is carried out which the otorrhynolaringologyst and a new consideration came out, concluding by pathological anatomy as tuberculosis. Taking into account the clinical picture and the anatomopathological firdings that do not corresponded inther with Sarcoidosis or Epidermoide carcinoma previously reported. The characteristics of this case led to this presentation

Avaliação da qualidade vocal de pacientes tratados de tuberculose laríngea antes e após terapia fonoaudiológica / Vocal quality evaluation of treated laringeal tuberculosis patients, before and after voice therapy

A Tuberculose Laríngea (TL) é a mais freqüente doença granulomatosa de laringe, podendo invadir vias aéreas e digestivas superiores, causando lesões mucosas. O envolvimento dos tecidos da laringe podem alterar a flexibilidade da túnica mucosa das pregas vocais e conseqüentemente alterar a qualidade vocal dos pacientes. Como conseqüência, a disfonia é o principal sintoma da TL, estando presente em 96 dos casos diagnosticados. Apesar da grande incidência, poucos estudos foram realizados, principalmente no tocante ao tratamento e evolução das seqüelas pós-infecção. O objetivo deste trabalho é avaliar a incidência da disfonia pós-tratamento de tuberculose laríngea (TL) e o efeito da fonoterapia na qualidade vocal destes pacientes. Num total de 23 pacientes com diagnóstico confirmado de TB tratados no IPEC-FIOCRUZ, sete foram submetidos à terapia fonoaudiológica por até 6 meses, sendo avaliados por videolaringoscopia e análise acústica vocal computadorizada antes, durante e após o fim da terapiaidade dos pacientes variou de 25 a 83 anos com média de 41,3 + 13,9 anos , sendo 5 mulheres e 18 homens. A disfonia esteve presente em 91,3 porcento dos pacientes com TL, sendo o primeiro sintoma em 82,6 porcento destes, só melhorando completamente após tratamento antituberculínico em 15,8 porcento. O envolvimento das pregas vocais ocorreu em 78,5 porcento, aritenóides em 65,2 porcento, epiglote em 65,2 porcento, pregas ariepiglóticas em 52,2 porcento, e pregas vestibulares em 43,5 porcento. Após fonoterapia, obtive-se melhoras estatisticamente significativas nos parâmetros Jitter, Shimmer, variabilidade de freqüência fundamental, tempo máximo de fonação e relação fricativas surda e sonora (S/Z). A incidência da disfonia após tratamento da TL é alta e a fonoterapia melhorou significativamente a qualidade vocal destes pacientes...

Laryngeal Tuberculosis (LT) is the most frequent granulomatous larynx desease.It can invade upper respiratory and digestive tracts provoking lesions on mucosa.Attacked larynx tissues can reduce the vocal folds mucosa flexibility. Therefore, thedysphony is the main symptom of LT, appearing in 96 percent of cases. Despite highincidence, studies about treatment and sequels evolution are few. The objective ofthis work is evaluate the dysphonia after LT treatment and voice therapy effect overvocal quality of patients. From 23 patients with LT confirmed diagnosis, treated atIPEC-FIOCRUZ, 7 of them were submitted to voice therapy along of 6 months. Theywere evaluated by telelaryngoscopy and vocal acoustic analysis on microcomputerbefore, along, and after therapy. The patients age rage was 25 to 83 years (avg. 41.3+ 13.9 years), being 5 women and 18 men. The dysphonia appeared in 91.3 percent of LTcases, being 82.6 percent of these cases the first symptom, and disappeared after LTtreatment only in 15.8 percent. The infection on vocal folds occurred in 78.5 percent , arytenoids in65.2 percent , epiglottis in 65.2 percent , aryepiglottis in 52.2 percent , and false vocal folds in 43.5 percent .After voice therapy, the patients had better vocal quality based on statistic analysis ofJitter, Shimmer, fundamental frequency variability, maximum phonation time,voiceless and voice fricative sounds S / Z parameters. There is high incidence ofdysphonia after LT treatment. The speech therapy greatly improved the vocal qualityfor these patients...

Clinical analysis of the diagnosis of laryngeal tuberculosis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the clinical characteristic and diagnosis of modern laryngeal tuberculosis.@*METHOD@#A retrospective research among 33 patients of laryngeal tuberculosis, with definitive pathological result, had been done in the laryngeal-endoscope room in our department.@*RESULT@#The main symptoms of laryngeal tuberculosis are hoarseness and sore throat. Most of the patients did not accompany with pulmonary tuberculosis (TB) (63.6%). Few of them accompany with low-grade fever, night sweat and malnutrition (24.2%). There are three types in the laryngeal-endoscope vision: edema type, hyperplasia type and ulcer exudation type. The positive rates of PPD and phlegm bacteria examination are respectively 87.9% and 68.4%. There can be seen in the pathological slides the interstitial phagocytes and giant cell reaction. Granuloma consisting of epithelioid cell and Langhans' cells is coexistent with necrotic tissue. Cheese necrosis is the typical characteristic of the disease.@*CONCLUSION@#Severe local symptoms of laryngeal with slightly general symptoms are the clinical characteristics of modern laryngeal tuberculosis. The diagnosis of it depends mainly on the process of the disease, laryngeal-endoscope examination and PPD examination combined with phlegm bacteria examination. And the final diagnosis is based on the pathological biopsy and tubercular bacillus culturing.

Flow-volume loops: clinical correlation

Flow volume loops are an essential part of spirometry testing. Their appearance can give information that can be helpful in the differential diagnosis of a patient's clinical condition. We present two clinical scenarios in which careful evaluation of the flow-volume loop gives an insight into the cause of the disease process.
