Presentations and Challenges in Tuberculosis of Head and Neck Region

ENT manifestation CCs in tuberculosis: a descriptive study

Background

An attempt was made to study ENT manifestations in tuberculosis.

Material and methods

A descriptive study was carried out among 200 patients with ENT manifestations of tuberculosis attending various departments at a government medical college hospital. Patients will be evaluated and followed up according to protocol. All patients diagnosed with tuberculosis were treated, according to the recent RNTCP guidelines using the CBNAAT testing.

Results

In the present study, 66% of patients with tuberculosis of the ear, nose, and throat region were females. Seventy-five percent of patients with tuberculosis of ENT and neck region were between the age group of 11 and 40 years. Cases of tubercular lymphadenitis (89.5%), tubercular laryngitis (4.5%), tubercular otitis media (3%), TB of the oral cavity (2%), and TB of the nose (1%) were seen. Painless lymph node enlargement was found in 91.62% of cases. Lymph node enlargement, hoarseness of voice, painless profuse otorrhoea, hearing loss, nasal obstruction, rhinorrhea, odynophagia, ulcers in the oral cavity, and tonsil enlargement were seen in patients of respective ENT tuberculosis. Concomitant pulmonary TB was found in 8.37% of cases of cervical TB, 100% of cases of laryngeal TB, 50% of cases of TB otitis media, 75% of cases of oral TB, and 50% of cases of nasal TB. Biopsy and CBNAAT have a promising role in tuberculosis management.

Conclusion

Early diagnosis of tuberculosis in ENT requires a high index of suspicion for patients non-responding to routine treatment

Diagnostic dilemma in a patient with nasopharyngeal tuberculosis: A case report and literature review

Tuberculosis remains a major cause of morbidity and mortality globally, with a global total of about 10 million people falling ill with it in 2020. Until the coronavirus (COVID-19) pandemic, tuberculosis was the leading cause of death from a single infectious agent. Nasopharyngeal tuberculosis is a rare type of extrapulmonary tuberculosis that may be either primary or secondary to pulmonary tuberculosis. Nasopharyngeal tuberculosis may be mistaken for nasopharyngeal carcinoma as both conditions may present with a nasopharyngeal mass and cervical lymph node enlargement. We present a case of nasopharyngeal tuberculosis secondary to pulmonary tuberculosis who presented without any nasal or respiratory symptoms. The patient presented with a cervical lymph node enlargement and a nasopharyngeal mass was detected on nasal endoscopy. Fine needle cytology from the cervical node and the initial biopsy report from the nasopharyngeal mass were not confirmatory, causing a diagnostic dilemma. A repeat biopsy from the nasopharyngeal mass with the demonstration of caseating granuloma and acid-fast bacilli in the specimen pointed to the diagnosis of nasopharyngeal tuberculosis. The patient responded well to the standard 6-month anti-tubercular regimen. Nasopharyngeal tuberculosis may mimic nasopharyngeal carcinoma and a repeat biopsy may be necessary to confirm the diagnosis.

Validity of Method for MTBC and NTM Detection in FNAB Specimens from Tuberculous Lymphadenitis Using Microscopy, XPERT MTB / RIF and Culture Method

Mycobacterium tuberculosis and Nontuberculous Mycobacteria usually cause infection in tuberculous lymphadenitis. To improve accuracy of the detection MTB and NTM bacteria it is necessary to select valid methods. This study aims to compare validity of diagnostic methods from FNAB specimens for determining tuberculous lymphadenitis patients. a descriptive observational laboratory study involved 35 samples were obtained from tuberculous lymphadenitis patients in Dr. Soetomo Hospital Surabaya East Java. All specimens examined Ziehl-Neelsen staining microscopy, Xpert MTB/RIF , culture method Middlebrook7H10 solid media and  MGIT as Gold standard. Identification of MTB dan NTM with SD Bioline TB Ag MPT64 and niacin paper strip BD . Used diagnostic test 2x2 to analyze sensitivity, specificity, negative predictive value and positive predictive value. Ziehl-Neelsen staining microscopy Sensitivity 83,33 %  and Specificity 95,65% of  , PPV  90,91%and NPV 91,67%, Diagnostic Accuracy 91,43 % . Xpert MTB/RIF Sensitivity 75% and Specificity 95,65% , PPV  90 % and NPV 88 %, Diagnostic Accuracy 88,57 % with 95% CI (Confidence Interval ) . Characteristics female dominated 23/35 (65.7%) while Male numbered 12/35 (34.3%), age range distribution of TB lymphadenitis patients is highest in young adults 17 years to 25 years as many as 15/35 (42.9%) the second highest is the age group of 36 years to 45 years by 8/35 (22.9%), Clinicial presentation are mostly lymph node enlargement in cervical  37% patients other locations supraclavicular ,mamae. Clinical symptoms mostly lymphadenopathy 31,5% and other lymphadenopathy with fever. Microscopy method still have the good validity shoul be conjunction with the  molecular rapid tests and culture as gold standard in determining the diagnosis of TB lymphadenitis.

An eight-year epidemiologic study of head and neck tuberculosis in Texas, USA

BACKGROUND

Head and neck tuberculosis (HNTB) especially cervical lymphadenopathy are the most common extrapulmonary indications of TB, but remain a diagnostic challenge. In this study, we describe and analyze the epidemiologic characteristics of HNTB on a population-level.

MATERIALS AND METHODS

We retrospectively assessed 547 HNTB cases reported to the Centers for Disease Control and Prevention's TB Genotyping Information Management System in Texas from 2009 to 2016 and compare and contrast differences between diagnosed exclusively HNTB and HNTB with concurrent pulmonary tuberculosis (PTB).

RESULTS

The majority of patients with HNTB were diagnosed with cervical lymphadenopathy (96.9%), age 25-44 (47.3%) and female (52.7%). Co-infection with human immunodeficiency virus, being homeless, excessive alcohol use within the past 12 months and drug use were more frequently seen for HNTB with concurrent pulmonary involvement compared to reported patients with exclusively HNTB. The highest prevalence of Mycobacterium tuberculosis lineage in exclusively HNTB was Euro-American L4 (52.3%), followed by Indo-Oceanic L1 (21.5%) and East-Asian L2 (13.1%). One multidrug resistant TB case was identified. Seven deaths were reported during treatment.

CONCLUSION

Our findings provide a better understanding of the epidemiology of HNTB and characteristics associated with the disease at the population-level, which is important in managing HNTB patients.

Clinical study of tuberculosis in the head and neck region-11 years' experience and a review of the literature

Tuberculosis (TB) is an infectious disease and major health concern. Head and neck tuberculosis (HNTB) is relatively rare, but can arise in many regions, including the lymph nodes, larynx, oral cavity and pharynx. We retrospectively reviewed the clinical records of 60 patients diagnosed with HNTB in our department between March 2005 and January 2016. A review and summary of previous HNTB articles published in PubMed since 1885 was also performed. The subjects consisted of 17 males and 43 females, and the average age of patients was 45 ± 14.67 years. The major clinical presentation was a lump or swelling, followed by an oral ulcer and skin fistula. The most common site of tuberculosis was in the cervical lymph node. Three patients also suffered from a malignant tumor in the head and neck region. A total of 980 papers involving 5881 patients were included in our literature review. The included subjects ranged in age from 15 months to 100 years with a male-to-female ratio of 1.5:1. The larynx (38.92%), cervical lymph nodes (38.28%) and oral cavity (9.92%) were the three most common development sites. 465 patients were positive according to a HIV test, and 40 patients had comorbidities with different types of tumors. Head and neck tuberculosis should always be considered during a differential diagnosis for lesions in the head and neck region. Early diagnosis and treatment can greatly enhance the therapeutic effect and patients’ quality of life.

Clinical and pathologic analyses of tuberculosis in the oral cavity: report of 11 cases

OBJECTIVE

The aim of this study was to analyze tuberculosis (TB) in the oral cavity according to clinical appearance, clinical differential diagnosis, treatment, and outcome.

STUDY DESIGN

We enrolled 11 patients with TB in the oral cavity between November 2012 and November 2016. Glossal lymphoid TB was excluded. Clinical symptoms, auxiliary examinations, treatments, and outcomes were recorded and analyzed.

RESULTS

The study population comprised 6 men and 5 women, with a mean age of 59 years. Five patients presented with ulcer, 5 with a mass, and 1 with osteomyelitis. Excisional biopsy was performed in 3 patients, mass resection in 7, and curettage of mandibular lesion in 1. After pathologic diagnosis of TB in the oral cavity in 8 patients; 6 of them underwent purified protein derivative examination, and 4 of them had positive results and received drug therapy. The mean follow-up period was 24.9 months, and there was no recurrence.

CONCLUSIONS

TB in the oral cavity is rare and has no specific clinical features. Pathology, acid-fast staining, polymerase chain reaction, and DNA testing for Mycobacterium tuberculosis are useful for final diagnosis. Surgery is recommended as the treatment of choice to achieve good clinical outcomes.
