Atypical presentation of oral and laryngeal tuberculosis in an adolescent.

Extrapulmonary manifestation of tuberculosis (TB) in the adolescent population in the head and neck region may be atypical in the site of involvement, symptomatology and clinical presentation. We report a case of the management of oral and laryngeal TB in an early adolescent female who presented with ulceration over the palate and tonsillar region with uvula destruction and laryngeal symptoms and aim to highlight the atypical extrapulmonary manifestations of TB in the head and neck region in adolescent age group.

Laryngeal tuberculosis, the great deceiver: A series of 10 cases.

BACKGROUND: Laryngeal involvement is rare in tuberculosis, representing around 1% of all cases of this infection worldwide. Given the larynx' location in the airway, this form of tuberculosis is of particular importance because it is highly contagious. With our hospital being in a high tuberculosis burden area, we propose to characterize the clinical presentation, evolution, and laryngoscopy findings of a series of laryngeal tuberculosis cases in order to reduce misdiagnosis. METHODS: Epidemiological and clinical data from 10 patients diagnosed with laryngeal tuberculosis in the Otorhinolaryngology department of (Blinded for manuscript) between January 2011 and December 2021 were retrieved and analyzed. RESULTS: There were eight males and two females. Seven patients had a history of smoking and alcohol abuse and four had silicosis. Hoarseness was the most reported symptom (n = 9). The most frequent site of involvement were the true vocal cords (n = 6). All patients but one had concomitant active pulmonary tuberculosis. Patients had full resolution of laryngeal symptoms between 4 and 16 weeks after initiating antituberculosis treatment. CONCLUSION: Laryngeal tuberculosis is indeed a great deceiver. On one hand it can look like a simple polypoid lesion or simulate laryngopharyngeal reflux; but on the other hand its risk factors, symptoms and appearance simulate laryngeal carcinoma like no other. Since most patients present with concomitant pulmonary tuberculosis, all suspect laryngeal lesions should perform a chest radiograph prior to rigid laryngoscopy. Antituberculosis treatment is effective in both alleviating symptoms and reducing the risk of transmission.

Laryngeal tuberculosis in the early 21st century. Literature review of clinical, diagnostic and therapeutic data, according to SWiM guidelines.

OBJECTIVES: Review of the scientific medical literature dedicated to clinical data, diagnosis and treatment for laryngeal tuberculosis published since the turn of the 21st century. MATERIAL AND METHODS: Search of the Medline, Cochrane and Embase databases for the period 2000-2022. Selection of cohorts and case reports documenting clinical data, diagnosis and treatment for laryngeal tuberculosis. RESULTS: In total, 119 articles were analyzed. Immunodepression, HIV infection, history of lung tuberculosis, general symptoms suggesting tuberculosis, smoking and associated laryngeal cancer were noted in 18%, 3%, 20% and 41% of cases, respectively. No pathognomonic symptoms or signs emerged. Voice impairment, of various types and severity, isolated and/or associated with other signs, was the most frequent laryngeal symptom, in 86% of cases. All laryngeal sites were involved, with numerous and various associations. Impaired laryngeal motion and tracheotomy were noted in 6% and 1% of cases, respectively. Time to diagnosis varied from less than 1month to 36months, for a median 3months, in case reports. Laryngeal tuberculosis was diagnosed bacteriologically with certainty in 28% of cases while diagnosis was based on indirect criteria and/or involvement of another site in the other 72%, with lung involvement in 54%. Treatment duration ranged from 6 to 24months (median, 6months), using 3 to 5 (median: 4) antitubercular antibiotics, with 4 used in 80% of cohorts and 77% of case reports. Overall rates of cure, death, treatment resistance, adverse events, and laryngeal sequelae were 99%, 0.5%, 0.5%, 6% and 5%, respectively. CONCLUSION: The clinical presentation and diagnostic difficulty in laryngeal tuberculosis did not change since the end of the 20th century. Quadritherapy is highly effective, with a low resistance rate and few adverse effects or laryngeal sequelae.

Clinical characteristics and prognosis of laryngeal tuberculosis combined with respiratory tuberculosis.

PURPOSE: To investigate the clinical characteristics, diagnosis and prognosis of patients with laryngeal tuberculosis (LTB) combined with respiratory tuberculosis. MATERIALS AND METHODS: A retrospective analysis was conducted on 134 patients who underwent endoscopy and were eventually diagnosed with LTB. The patients' demographic characteristics, clinical manifestations, endoscopic features, auxiliary examination, imaging examination and prognostic characteristics were analyzed. RESULTS: LTB patients had a median age of 45.5 years (range from 12 to 87 years) and a median course of 3.0 months (range from 0.1 to 72 months). The patients' symptoms mainly presented as hoarseness (97.0 %), abnormal sensation of pharyngeal (49.3 %), cough and sputum (41.0 %), pharyngalgia (39.6 %), dysphagia (10.4 %) and dyspnea (8.2 %). The positive rate of tuberculous symptoms was 25.4 %. Endoscopic features showed that the lesions mainly involved the glottis (87.3 %), presenting as unilateral lesions (66.7 %), near-full-length involvement (88.0 %), with mucosal waves significantly reduced (86.3 %), followed by supraglottis (43.3 %), subglottis (24.6 %) and the pharynx (15.7 %). The lesions may present as granulomatous proliferation (66.4 %), ulceration (65.7 %) or swelling and exudation (51.5 %). A total of 75 patients (56.0 %) were finally diagnosed with combined pulmonary tuberculosis (PTB), with a positive chest X-ray rate of 25.6 % and a positive chest CT rate of 71.2 %. A total of 42 patients who received anti-tuberculosis treatment were followed up, and 73.8 % of patients had significant improvement in symptoms. The morphology of the pharyngeal and laryngeal mucosa returned to basically normal (59.4 %) or scar-like (34.4 %). CONCLUSIONS: LTB is usually found in middle-aged men, and patients' symptoms are mainly hoarseness, abnormal sensation of pharyngeal, pharyngalgia, cough and sputum, and can be combined with tuberculous symptoms. These lesions mainly involve multiple subregions, mainly in the glottis, and can be combined with pharyngeal involvement. There were various types of lesions. Half of the patients were complicated with PTB, and chest CT was superior to X-ray in the detection of pulmonary lesions. After regular anti-tuberculosis treatment, the symptoms and morphology of the pharyngeal and laryngeal mucosa of most patients were significantly improved.

Laryngeal tuberculosis: about 04 cases.

The purpose of this study is to present epidemiological, clinical, radiological, histological characteristics and treatment of laryngeal tuberculosis. It is also aimed at making the point about diagnosis difficulties. This retrospective study was conducted over three years; it concerned 4 cases, 3 males and one female. The average age was 35 years. Three of the 4 cases have had a cervical CT scan. All patients have had a laryngoscopy with biopsy and anatomopathological study. The onset modes of the disease have been progressive for all the patients. Topographical study has shown two epiglottic locations, one at the vocal cords and the other one at the posterior commissure. The diagnosis was orientated in the 3 cases by the CT scan and confirmed by anatomopathological exam in all cases. All patients have received anti-TB drugs with good evolution. The laryngeal location of tuberculosis is unusual. The clinical picture is nonspecific, raising the issue of differential diagnosis with tumor pathology. Sectional imaging and CT scan can guide the diagnosis and a positive diagnosis is often discovered on the occasion of a tumor biopsy of a pseudo-tumor lesion. Treatment is based on anti-TB drugs.

[Isolated laryngeal tuberculosis as an uncommon manifestation of extrapulmonary tuberculosis in adults: a case report]. / Tuberculose laryngée isolée de l'adulte: localisation extra pulmonaire exceptionnelle (à propos d'un cas).

Isolated laryngeal tuberculosis is rare and sometimes difficult to diagnose. It is the most common cause of laryngeal granuloma. We here report the case of a 58-year-old man, with no particular past medical history, hospitalized due to paroxysmal laryngeal dyspnea, dysphagia to solid foods and dysphonia evolving for 6 months without other associated signs. Laryngoscopic examination showed polyploid formation masking the glottic floor. Histological examination revealed epithelioid and gigantocellular granuloma, without caseous necrosis. Direct microscopic examination and culture were negative. The diagnosis of isolated laryngeal tuberculosis was made based on the endemicity in our country and the absence of other arguments in favor of another type of granulomatosis. Anti-tuberculosis therapy, combined with oral corticosteroids, was indicated based on the presence of severe upper airway edema and symptoms were resolved after 40 days of treatment.

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.

Laryngeal tuberculosis: a neglected diagnosis.

A 24-year-old woman visited the Ear Nose Throat (ENT) outpatient department with complaints of hoarseness for 2 months not responding to conservative management. Laryngoscopic examination revealed a whitish ulceroproliferative lesion in the anterior commissure and anterior two-thirds of bilateral true vocal cords with surrounding necrosis. In view of the above findings, the patient was planned for biopsy under general anaesthesia. Intraoperative findings showed multiple whitish necrotic friable tissue involving anterior two-thirds of bilateral false vocal cords, ventricle, bilateral true vocal cords, both aryepiglottic folds and laryngeal surface of epiglottis. Postoperative histopathology was consistent with tuberculosis. A pulmonology consultation was taken, and the patient was started on anti-tuberculosis chemotherapy. One month post therapy, the voice was symptomatically better. A flexible fibreoptic laryngoscopic examination was done, which revealed almost complete resolution of the lesion with minimal ulceration at the anterior one-third of right true vocal cord.

Primary tonsillar tuberculosis in a pediatric patient: Case report and literature review.

RATIONALE: Tuberculosis is an entity that usually affects the lungs, although extrapulmonary sites can also be involved. Tonsils are rarely affected, especially in the absence of pulmonary disease, primary tonsillar tuberculosis being a diagnostic challenge for the clinician. PATIENT CONCERNS: We present the case of a 14-year-old female teenager, presented to our Pediatric Service with a 14-day history of dysphagia, odynophagia and left reflex otalgia associated with a 5 kg weight loss. Clinical examination revealed mild pharyngeal erythema, marked enlargement of the left tonsil infiltrating the lateral pharyngeal wall and the uvula and painful, mobile, nonadherent to deep bilateral latero-cervical adenopathy. DIAGNOSIS: Positive interferon-gamma release assay (QuantiFERON-TB gold). Mantoux test reading was 16 mm. INTERVENTIONS: During hospitalization, the patient received Clindamycin and Gentamicin for 3 days i.v., with discrete relief of symptoms and inflammatory markers. On the 4th day of hospitalization, treatment with Imipenem/Cilastin is started for 7 days in micro-perfusion, with tonsil hypertrophy decrease in size and favorable clinical evolution. OUTCOME: Tonsil hypertrophy decreased in size and patient had a favorable clinical evolution. At discharge, the patient was given a 6-month course of anti-tuberculous drug. LESSONS: The particularity of this case is represented by the rarity of primary tuberculosis of tonsils in children, with unilateral involvement, displaying at the same time a common issue encountered in the current practice: the limitations and the difficult course of setting the diagnosis due to the involvement of relatives in the medical act.

[The history of tuberculosis of the larynx]. / Zur Geschichte der Kehlkopftuberkulose.

The tuberculosis of the larynx was an incurable deadly infectious disease until the introduction of antituberculous drugs in therapy. Since the 18th century medical specialists investigated this kind of tuberculosis. Progresses of laryngeal diagnostic made possible a local treatment with drugs, operations and experiments with X-rays. After the development of antituberculous drugs, tuberculosis of the larynx became a curable disease.

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)

Laryngeal tuberculosis in renal transplant recipients: A case report and review of the literature.

Renal allograft recipients are at greater risk of developing tuberculosis than the general population. A woman with a kidney transplant was admitted to our emergency department with high temperature, dysphonia, odynophagia, and asthenia. The final diagnosis was laryngeal tuberculosis. Multidisciplinary collaboration enabled accurate diagnosis and successful treatment. Laryngeal tuberculosis should be considered in renal allograft recipients with hoarseness. A more rapid diagnosis of tuberculosis in renal transplant recipients is desirable when the site involved, such as the larynx, exhibits specific manifestations and the patient exhibits specific symptoms. In these cases, prognosis is excellent, and with adequate treatment a complete recovery is often achieved.

Head and neck tuberculosis: Literature review and meta-analysis.

BACKGROUND: Head and neck tuberculosis (HNTB), including cervical lymphadenopathy, is the most common extrapulmonary manifestation of TB. The proposed study investigated the epidemiologic and clinical characteristics of HNTB. MATERIALS AND METHODS: A literature search was conducted via PubMed, Embase, Cochrane Library and Wanfang for keywords (tuberculosis, head and neck, laryngeal, pharyngeal, tongue, oropharyngeal, nasopharyngeal, and oral cavity). Scientific articles published from January 1990 through July 2017 were selected and reviewed to assess the epidemiology, presentation, diagnosis and treatment of HNTB disease. RESULTS: Results from the included 57 studies revealed that the majority of HNTB cases were age<40 years and female. The most common HNTB sites were cervical lymph nodes (87.9%), followed by larynx (8.7%). Involvement of other HN-regions was rare (3.4%). Multidrug resistant TB was not common among the majority of studies. Given the paucibacillary nature of HNTB, sputum tests did not have a good performance on HNTB diagnosis. Most of HNTB cases were diagnosed by fine-needle aspiration, cytology and excision biopsies in combination with clinical presentations. CONCLUSION: HNTB disease is an important manifestation in the diagnostic process in an otolaryngologist practice. The developments of rapid, ultrasensitive, simple and cost-effective high-throughput methods for early diagnosis of HNTB are urgently needed.

Primary Laryngeal Tuberculosis: Our Experiences at a Tertiary Care Teaching Hospital in Eastern India.

INTRODUCTION: Primary laryngeal tuberculosis is a chronic bacterial infection of the larynx by Mycobacterium tuberculosis without affecting the lungs. It is a rare type of extrapulmonary tuberculosis seen in clinical practice. OBJECTIVES: This study aimed to evaluate the clinical presentation, diagnosis, and treatment of primary laryngeal tuberculosis at a tertiary care teaching hospital in eastern India. MATERIALS AND METHODS: This is a retrospective study of 11 cases of primary laryngeal tuberculosis managed between December 2013 and January 2018. The detailed clinical presentations, investigations, and treatment of primary laryngeal tuberculosis of the patients were studied. RESULTS: Primary laryngeal tuberculosis is common in men with mean age of 38.63 years. Hoarseness of the voice is the most common symptom, and the most common site for primary laryngeal tuberculosis is the vocal fold with ulcerative lesion. Endoscopic examinations of the larynx in laryngeal tuberculosis are nonspecific and are to be confused with laryngeal cancer. Histopathological and bacteriological examinations are confirmatory tests for the diagnosis. After confirmation of the diagnosis, all patients had taken antitubercular therapy for 6 months, which gave excellent outcome. CONCLUSIONS: Delayed diagnosis or untreatable laryngeal tuberculosis will lead to high morbidity and mortality of the patient. Although primary laryngeal tuberculosis has nonspecific clinical presentations, it is very important to have a high index of suspiciousness to rule out tubercular lesion in the larynx as this disease is curable.

Primary Laryngeal Tuberculosis: A Series of 15 Cases.

Tuberculosis usually involves the lungs, but can also involve various other organs. Extra pulmonary tuberculosis is very rarely confined to the larynx in the absence of an associated pulmonary lesion. In this retrospective study, clinicopathological characteristics of patients with final diagnosis of laryngeal tuberculosis (LTB) were reviewed. The diagnosis of LTB was based on: (1) the existence of chronic granulomatous inflammation with caseous necrosis in the histopathology of laryngeal lesions or (2) the presence of laryngeal lesions with atypical histopathology (chronic granulomatous inflammation) which had a complete response to anti-tuberculosis therapy. Fifteen cases with a diagnosis of LTB were collected. The patients' age ranged between 24 and 75 years with a mean of 49 years. On laryngoscopy, 66.6% of cases (10/15) had an ulceroproliferative lesion while the remaining 33.3% of cases (5/15) had an exophytic growth. The pathology of laryngeal lesions revealed chronic granulomatous inflammation with caseous necrosis in nine cases and chronic granulomatous inflammation without necrosis in six cases. Nine out of 15 cases (60%) showed presence of acid-fast bacilli on Ziehl-Neelsen stain. Any evidence of pulmonary tuberculosis was ruled out by chest X-ray findings. The response to anti-tuberculosis therapy was desirable in all patients. Since the introduction of anti-tuberculous therapy, the incidence of LTB has declined. However, with the incidence of TB increasing, the overall incidence of laryngeal involvement may be on the rise. This study highlights the importance to consider the rare possibility of LTB in the presence of non-specific clinical and laryngoscopic signs and to confirm this by histological examination.

[The clinical and bacteriological study of the effectiveness of the application of silver nanoparticle for the treatment of tuberculosis]. / Kliniko-bakteriologicheskoe issledovanie éffektivnosti ispol'zovaniia nanochastits serebra dlia lecheniia tuberkuleza verkhnikh dykhatel'nykh putei.

The objective of the present study was to evaluate the expediency of the application of nano-scale silver preparations, argovit-C and vitargol, differing in concentration for the treatment of tuberculosis of the upper respiratory tract. The study was carried out based at the Karachaevo-Cherkessian TB dispensary. It has been demonstrated that the 3.3% solution of argovit-C possessed of the 100% bactericidal activity with respect to the medically-resistant mycobacteria at both maximum and minimal concentrations of isoniazid. Based on these findings, this preparation was chosen for the clinical study. It was shown to exhibit a higher therapeutic effectiveness in comparison with the standard anti-tuberculosis treatment. The authors conclude that the inhalation of the 3.3% argovit-C solution twice daily for 10 minutes during 2 months can be recommended for the local treatment of laryngeal tuberculosis.
