Extra-laryngeal head and neck tuberculosis

Clinical periodontal diagnosis

Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior to periodontal therapy, following active therapy, and during long-term supportive care. In addition, patient-reported outcomes such as increased tooth mobility, migration, and tilting should also be considered. More important to the patient, however, is the fact that assessment of signs of periodontal diseases must be followed by an appropriate treatment plan. Furthermore, it should be realized that clinical and radiographic periodontal diagnosis is based on signs which may not reflect the presence of active disease but rather represent the sequelae of a previous bacterial challenge. Hence, the aim of the present review is to provide a summary of clinical and radiographic diagnostic criteria required to classify patients with periodontal health or disease.

Aural tuberculosis at the start of the 21st century. Literature review according to SWiM guidelines. Part 2: Treatment

OBJECTIVES

Systematic review of the scientific literature dedicated to treatment modalities and results for aural tuberculosis published since the start of the 21^st century.

MATERIAL AND METHODS

Search of the Medline, Cochrane and Embase databases for the period 2000 - 2020. Selection of articles in English, French and Spanish devoted to clinical cases and series documenting treatment of auricular tuberculosis. Extraction of data on pre-established files documenting treatment modalities and results. Reading of articles by two authors. Analysis performed according to SWiM guidelines, evaluating cure, tuberculosis-related death, treatment-related complications, improvement in facial palsy, and hearing sequelae rates.

RESULTS

One hundred and twenty eight articles: 118 case reports (159 patients) and 10 cohorts (177 patients) from 42 countries were analyzed. Female/male sex ratio was 1.2 with ages ranging from 1 month to 87 years. Medical treatment consisted in 5 to 24 months' antitubercular antibiotic treatment using 2 to 8 antibiotics. Mastoidectomy, tympanoplasty and facial nerve decompression were associated to medical treatment in 64.7%, 17.4% and 6.2% of cases, respectively. Overall rates of cure, death, treatment-related complications, facial sequelae and hearing sequelae were 96.8%, 2%, 9.5%, 35.8% and 75.5%. In case reports, BCG vaccination did not appear to protect against facial palsy and severe intracranial complications (P>0.6). There was no significant correlation (P>0.3) between death and the clinical variables tested, and facial nerve decompression did not appear to influence outcome for facial function (P=0.4).

CONCLUSION

Medical treatment is very effective but not without risk of death, complications and sequelae. It is the same as for pulmonary tuberculosis. Indications for and benefit of major auricular surgery during medical treatment deserve further studies.

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.

Viral, bacterial, and fungal infections of the oral mucosa: Types, incidence, predisposing factors, diagnostic algorithms, and management

For millions of years, microbiota residing within us, including those in the oral cavity, coexisted in a harmonious symbiotic fashion that provided a quintessential foundation for human health. It is now clear that disruption of such a healthy relationship leading to microbial dysbiosis causes a wide array of infections, ranging from localized, mild, superficial infections to deep, disseminated life-threatening diseases. With recent advances in research, diagnostics, and improved surveillance we are witnessing an array of emerging and re-emerging oral infections and orofacial manifestations of systemic infections. Orofacial infections may cause significant discomfort to the patients and unnecessary economic burden. Thus, the early recognition of such infections is paramount for holistic patient management, and oral clinicians have a critical role in recognizing, diagnosing, managing, and preventing either new or old orofacial infections. This paper aims to provide an update on current understanding of well-established and emerging viral, bacterial, and fungal infections manifesting in the human oral cavity.

Tuberculosis of the Oral Cavity Misdiagnosed as Precancerous Lesion

Introduction

The aim of this case report was to discuss an extremely rare oral lesion as a result of primary pulmonary tuberculosis.

Case report

In this case report, the patient with refractory painless ulceration at ventral surface of the tongue was described. Detailed medical history was taken followed by clinical examination of the oral mucosa and palpation of regional lymph nodes. Clinical examination revealed ulceration on the patient’s ventro-lateral surface of the tongue, approximately two centimeters in diameter. Palpation of regional lymph nodes has not revealed enlargement. The toluidine blue test of the suspected lesion was performed at each control examination. Biopsy samples for histopathologic diagnosis were taken three times. The analysis of the first biopsy sample for histopathology revealed a non-specific inflammation, the second biopsy revealed a caseous necrosis without positive Ziehl-Neelsen staining and the third biopsy revealed a granulomatous inflammation which was highly suspicious of sarcoidosis. During hospitalization, the patient underwent a complete physical examination, and laboratory and radiological diagnostics. Physical chest examination revealed bilaterally coarse crepitations and laboratory findings of his complete blood count revealed normocytic anemia of chronic disease. Radiographic examination of lungs showed multiple small nodules bilaterally and positive direct sputum smear.

Conclusion

Although oral tuberculosis is a rare condition, it must be taken into account in differential diagnosis of refractory painless oral ulcers.

Upper Respiratory Tract Tuberculosis

Upper respiratory tract involvement in cases of tuberculosis (TB) of the head and neck continues to be described in the most recent reports from several different regions, including some from developed countries. Laryngeal TB is the most common of all forms of upper respiratory tract TB (URT-TB). Pulmonary lesions in URT-TB are present in about 20% of adults and about 50 to 60% of children. Systemic manifestations are uncommon. URT-TB is especially seen in patients with a variety of risk factors, such as the presence of human immunodeficiency virus (HIV) infection, diabetes, smoking, alcoholism, drug abuse, malignancies, and use of immunosuppressive drugs. Nodules or ulcerative lesions are seen on morphological examination. Endoscopic examination is required for mucosal lesions. Diagnosis of TB is suspected on an epidemiological basis in high-prevalence countries or from the failure of a patient to respond to routine treatment. Smear and/or histopathological examinations help in establishing the final etiological diagnosis. Treatment includes standard anti-TB chemotherapy for at least 6 months with four primary drugs during the initial intensive phase of 2 months and two or three primary drugs during the remaining maintenance phase of 4 months. Treatment is modified on the basis of culture and sensitivity reports in cases of suspected drug resistance. Surgical intervention may be required for some patients with abscess formation and progressive disease unresponsive to medical therapy. Airway obstruction, although rare, even in fulminant cases may require tracheostomy for relief.

A rare case of chronic otitis externa due to Mycobacterium tuberculosis

Chronic otitis externa due to Mycobacterium tuberculosis complex is extremely rare and very few cases have been presented in the medical literature. We report here the case of an immunocompetent 68-year-old male with chronic auricular drainage, otalgia, hearing loss, external ear canal and tympanic membrane thickening for 3 years who was ultimately diagnosed with tuberculous chronic otitis externa on biopsy of external auditory canal granulation tissue using molecular diagnostic techniques. Later, sputum cultures were positive for Mycobacterium tuberculosis complex indicating disseminated tuberculosis. However, two plausible explanations could be pulmonary TB that disseminated to the ear canal with evidence of middle and outer otitis, or upper airway/nasopharyngeal involvement with direct extension into the middle and outer ear canals. Although extremely rare, extrapulmonary laryngeal head and neck tuberculosis should be considered in immunocompetent patients who present with chronic otitis without prior known exposure to tuberculosis when they fail standard therapy and in whom no other microbiologic cause can be identified.

[The clinical manifestations and diagnostics of otitis media caused by tuberculosis]

The objective of the present study was to clarify the characteristic pathognomonic features of middle ear lesions associated with tuberculosis and the approaches to their diagnostics under the present-day conditions. The study included 11 cases (18 ears) of tuberculosis otitis media and the related lesions of the mastoid process diagnosed with the use of clinical, roentgenological, cytological, bacteriological, pathomorphological, and molecular-genetic methods (including PCR diagnostics). The primary localization of tuberculosis in the middle ear was documented in 6 patients; in 5 patients, it was associated with pulmonary involvement. Five patients presented with smoldering exudative otitis media and the remaining six ones with suppurative perforating otitis media. The tuberculous process was diagnosed with the use of various methods including clinical examination, bacteriological (9%), cytological (27.3%), pathomorphological (18%) studies, and PCR diagnostics (55%). Diagnosis was made within a period from 1 month to 1.5 years after the application of the patients for medical assistance which suggests the difficulty of verification of tuberculous etiology of the disease of the middle ear. It is concluded that the high index of suspicion in the case of smoldering middle ear pathology facilitates its early diagnostics and successful treatment.

Oral Manifestations of Tuberculosis: Step towards Early Diagnosis

Tuberculosis, as known universally, is a chronic infectious disease that can affect any part of the body including mouth. It usually affects the lungs, TB bacilli can spread hematogenously to other parts of the body and this also includes mandible or maxilla. It can occur in the mouth involving the tongue with very unusual features and forms. So oral lesions, although rare, are very important for early diagnosis and interception of primary tuberculosis.

Tuberculosis of the middle ear and nasal passage: A case report

The following report highlights the case of a 55-year-old female with nasal and middle ear tuberculosis. The diagnosis was confirmed using imagery, histopathological biopsy reports, and Polymerase chain reaction (TB-PCR). The patient was treated with rifampicin (10mg/kg), isoniazid (5mg/kg) and pyrazinamide (25mg/kg) for 9months. No recurrence was observed after one year of follow-up examination. Both nasal tuberculosis and tuberculous otitis media are currently considered rare diseases, yet if they are evaluated rapidly, there will be a good response to therapy without the need for surgery.

[Head and neck tuberculosis - still current problem in ENT practice]

INTRODUCTION

It is estimated that between XVI and XIX century one fourth of European population died of tuberculosis. Nowadays tuberculosis is still one of the most important infectious diseases. In 2009 estimately 9 million new cases were registered worldwide, mortality due tuberculosis reached 1.5 million. In Poland extrapulmonary tuberculosis is rare (7% of overall morbidity) and most commonly affects pleura, lymph nodes, bones, joints and genitourinary system. Head and neck tuberculosis is rare and causes many diagnostics problems.

METHODS

Retrospective analysis of case histories of patients admitted to ENT Department of Silesian Medical University in Katowice.

RESULTS

Between 1993 and 2010 four cases of head and neck tuberculosis were diagnosed in our Clinic. Two of patients were admitted to the hospital with symptoms of laryngeal tumor such as difficulty in swallowing. During direct laryngoscopy tissue specimens were taken. Examination of the third patient showed tumor located below left angle of mandibule. During superficial parotidectomy tumor was removed. In the fourth registered case tuberculosis manifested as tumor of nasopharynx. In every case which is mentioned above pathology reports revealed epithelioid cell granulomas with caseous necrosis typical for tuberculosis. Patients underwent tuberculostatic treatment.

CONCLUSION

Rare occurrence and lack of characteristic symptoms of head and neck tuberculosis often lead to misdiagnosis. Histopathological examination is the most important diagnostic procedure. Microbiological examination is difficult in extrapulmonary tuberculosis, because of low concentration of pathogens in specimens. Tuberculostatic therapy is the leading method of treatment in every case of tuberculosis.

Tuberculosis of the oral cavity affecting alveolus: a case report

We report a first case of tuberculosis of oral cavity affecting the left alveolus from Nepal in a 63-year-old male who came to otorhinolaryngology outpatient department with a complaint of an ulcer in the oral cavity and pain in bilateral ear and throat. An ulcer measuring 1.8 cm in diameter with irregular friable margin and bleeding on touch was found in the left upper alveolar region of the oral cavity. Biopsy from the ulcer margin revealed histological features of necrotizing granulomatous lesion. Stain for acid fast bacilli was positive.

Coinfections associated with human immunodeficiency virus infection: workshop 1A

The importance of opportunistic pathogens in HIV disease has been demonstrated from the onset of the epidemic. This workshop aimed to review the evidence for the role of oral microorganisms in HIV-related periodontal disease and HIV transmission and the effect of HIV therapy on periodontal disease. Despite being a common copathogen, tuberculosis seems to have limited oral presentation. The oral manifestations seem to have little impact on the individual and, once diagnosed, are responsive to chemotherapy. The participants debated the available evidence on the role of microorganisms and whether further research was warranted and justified. Although the effects of lipodystrophy on facial aesthetics may be profound and may markedly affect quality of life, there is no evidence to suggest a direct effect on the oral cavity. Though of interest to oral health care workers, lipodystrophy and associated metabolic syndromes were thought to be further investigated by other, more appropriate groups.

Roles of an anti-tuberculosis medication and surgery in patients with tuberculous otitis media

CONCLUSION

The standard treatment for tuberculous otitis media (TOM) without complications consists of anti-tuberculosis (anti-TB) medication, with which we experienced good treatment outcomes. However, surgery is required for recovery of anatomy and hearing function.

OBJECTIVE

To determine the clinical characteristics of TOM that might optimize diagnosis and to evaluate the differences in clinical courses between patients treated with and without surgery.

METHODS

We analyzed 14 patients (16 ears) who had been diagnosed and treated for TOM. Radiologic findings, laboratory data, and audiometry results were also evaluated. Patients were divided into a chemotherapy group and a surgery group according to treatment modality.

RESULTS

Temporal bone CT (TBCT) showed total occupation of the tympanic cavity by soft tissue and little evidence of ossicular erosion. In the chemotherapy group, dry ears were obtained in all but one patient (14 ears) after treatment. Normalized tympanic membrane (TM) was found in 50% in the chemotherapy group and in 75% in the surgery group. The air-bone gap (ABG) changed from 40.3 +/- 2.5 dB to 47.0 +/- 19.2 dB in the chemotherapy group and from 35.2 +/- 7.6 dB to 30.2 +/- 11.4 dB in the surgery group. After treatment, ABG improved by > 10 dB in one ear in the chemotherapy group and in four ears in the surgery group.

[Tuberculous otitis media]

Tuberculous otitis media is a rare disease. Its diagnosis is often made late. We report the case of a 13-year-old girl presenting with a right chronic otitis media and a massive and painful cervical adenitis. High resolution CT-scan revealed cervical and mediastinal adenitis associated with extensive lesions involving the middle ear, mastoid air cells, and sphenoidal bone. The diagnosis of tuberculous otitis media was made on a positive tuberculin skin test and on the identification of Mycobacterium tuberculosis in gastric juices. The young girl progressed well after 9 months of antituberculous chemotherapy.

À propos d'un cas d'otite tuberculeuse primitive compliquée de méningoencéphalite au complexe pédiatrique de Bangui (République centrafricaine)

The authors report a case of fatal tuberculous meningoencephalitis following chronic bilateral otitis media in a child. Mycobacterium tuberculosis was identified in the CSF and in the otitis secretions. There were no pulmonary tuberculosis signs, thus the tuberculous otitis was considered as primary. In high tuberculosis endemic areas like Central African Republic it is important to consider tuberculosis, in chronic otitis media resistant to non specific therapy, and to reinforce the immunization programs for children.

Tuberculous otitis media: a significant diagnostic challenge

OBJECTIVE

This study was undertaken to revise the diagnostic characteristics of tuberculous otitis media (TOM), a disorder that is often diagnosed late, leading to delay in specific treatment.

STUDY DESIGN AND SETTING

Retrospective study of a longitudinal series of 10 TOM patients over a 7-year period at an institutional referral center.

RESULTS

Most patients showed intractable otorrhea, moderately severe hearing loss, and necrotic eardrums with granulation tissue and single perforations. Multiple perforations, facial palsy, and cervical adenopathies were rare (<10% of patients). CT generally showed soft tissue involvement of the middle ear without bone erosion. The most effective laboratory test microbiological culture of exudate (diagnostic efficacy 71%). Specific antibiotic treatment was effective in all cases.

CONCLUSION

The diagnosis of TOM remains a significant challenge for otorhinolaryngologists.

SIGNIFICANCE

If there are strong clinical grounds for suspicion, standard laboratory tests for tuberculosis should be repeated even if initially negative.

Labial tuberculosis: a unique cause of lip swelling complicating HIV infection

BACKGROUND

HIV disease has many oral manifestations including tuberculosis, which most commonly presents as irregular ulceration of the tongue or the palate. We detail an HIV-infected patient found to have tuberculosis of the lip.

CONCLUSIONS

To our knowledge tuberculosis of the lips has never been reported in conjunction with HIV infection, and in this case establishing the oral diagnosis resulted in the diagnosis of disseminated disease.
