Infections due to nontuberculous mycobacteria in kidney, heart and liver transplant recipients. Nontuberculous mycobacteria (NTM) are an emerging cause of infections, including chronic lymphadenitis in children. Experts believe prevalence is increasing [2]; however, population-based data to substantiate these reports are lacking because in most jurisdictions, neither laboratory isolation of, nor disease due to, NTM is reportable to public health authorities. As the mycobacteria grow and deplete the oxygen present, the indicator fluoresces when subjected to ultraviolet light. In: Anderson WAD, Kissane JM, eds. 2020 Jul 9;9(7):553. doi: 10.3390/pathogens9070553. The disease is usually unilateral, occurring in the submandibular or preauricular area.

Surgical excision of NTM-infected lymph nodes is an effective diagnostic and therapeutic approach. Over 150 species have been described and the number continues to increase with improved isolation and identification techniques 1. Tuberculin skin test produced an induration in 81.0% of cases (diameter, 4-17 mm). Its frequency has increased over the past few decades. The diagnostic criteria were either culture of the organism from the affected lymph node (n=68), or, when culture was negative, a positive skin test with non-tuberculous mycobacterial antigens and negative skin test responses to tuberculin purified protein derivative … Experience from a tertiary care paediatric centre on non-tuberculous mycobacterial infections. Complications were few and included scar in three children and one case of transient facial nerve palsy. Most frequently children and young adults are affected (11-30 years of age) and there … Usually, they are opportunistic pathogens with variable degrees of virulence. When total surgical excision is not feasible, a combination of partial excision with a clarithromycin-including drug regimen appears safe, effective and causes milder and fewer complications than surgery alone.

NLM Despite modern diagnostic techniques for NTM infections their prompt and accurate diagnosis is still difficult. Nontuberculous mycobacteria (NTM) are a common cause of chronic cervicofacial lymphadenitis in children, especially those aged 1–5 years [1]. NTM can be isolated from a variety of environmental sources including water, food products, domestic animals, and soil; human exposure is typically from soil to the oral cavity and respiratory tract. Nontuberculous mycobacterial lymphadenitides.  |  1999 Jan;28(1):123-9. doi: 10.1086/515091. All 22 patients underwent surgical excision of affected nodes. Lymphadenitides caused by nontuberculous mycobacteria. Non-tuberculosis mycobacteria disease, simulating TB infection, can sometimes present with constitutional symptoms. It affects children aged 1–5 years and is rare after age 10 years, unlike tuberculous lymphadenitis. To identify risk factors for NTM lymphadenitis, particularly complicated disease, we collected epidemiologic, clinical, and microbiological data on 138 cases of NTM lymphadenitis in children across 13 centers in Germany and Austria. Asensi V, Palacios JJ, Rivas-Carmenado M, Suárez-Zarracina T, Garcia-Carus E, Fernández LM, Torres HE, Fierer J, Carton JA. Clinical and pathologic features with Mycobacterium fortuitum infections. Non‐tuberculous mycobacteria (NTM) is known to cause four clinical syndromes in humans: progressive pulmonary disease, superficial lymphadenitis, disseminated disease, and skin/soft tissue infection. NTM are also referred to as atypical mycobacteria, mycobacteria other than tuberculosis (MOTT), or environmental mycobacteria. Nontuberculous mycobacteria (NTM) are organisms commonly found in soil and water in many parts of the world. The aims of this study were to estimate the incidence of lymphadenitis due to NTM in children in Cyprus and to describe the characteristics, diagnostic approach, management and outcome of such infections. Conclusion: Nontuberculous mycobacteria (NTM) are mycobacteria other than M. tuberculosis (the cause of tuberculosis) and M. leprae (the cause of leprosy). Background: Non-tuberculous mycobacteria (NTM) constitute an important cause of cervical lymphadenitis in immunocompetent children. Pathology, vol. 2.
