Abstract
Background The epidemiology of nontuberculous mycobacteria (NTM) infections in the pediatric population is not well described. We estimated the incidence of NTM infection in Wisconsin children and adolescents, and the frequency and type of infection caused by different NTM pathogens. Associations between NTM infection and race/ethnicity and social disadvantage, respectively, were also investigated. Methods This retrospective cohort study evaluated reports of NTM infection in Wisconsin residents under 18 years of age submitted to a state-wide database between 2011 and 2018. Demographics of the cohort, including a social disadvantage score (Area Deprivation Index (ADI)), are described. Specimen type and NTM species are enumerated for reported isolates. Results There were 224 NTM isolates from 212 children and adolescents. Median age of participants was 3 years; 55 % were female. Cumulative incidence did not vary significantly between the larger racial groups or for the various ADI score groups. Compared to white participants (157), there was a significantly lower cumulative incidence of NTM infection in multiracial individuals (2). Mycobacterium avium complex (MAC) was the most frequently isolated organism (69 %). The majority of isolates (52 %) were from skin and soft tissue, which included lymph node specimens. Annual incidence did not vary significantly over the study period. Conclusions The epidemiology of pediatric NTM infections in this cohort is consistent with previous pediatric reports of higher rate of infection in females and predominance of skin and soft tissue infections. Disparities in disease burden across racial/ethnic and socio-economic groups were not demonstrated, but these factors should be further explored in larger pediatric studies of diverse U.S. populations.

Abstract
OBJECTIVES This study aims to determine the overall incidence of medical and surgical admissions related to non-tuberculous mycobacterial cervicofacial lymphadenitis (NTMCL) and determine if rates vary by geographic region in the US. It also aims to assess if the relative frequency of varying treatment modalities for NTMCL differ among geographic regions. STUDY DESIGN Population-based inpatient registry analysis. SETTING Academic medical center. METHODS The Kids' Inpatient Database (2016 and 2019) was used to determine NTMCL-related admissions and common head and neck procedures performed during these admissions were identified. Analysis was performed on regional differences in demographic factors and procedures performed during NTMCL-related admissions. RESULTS There were 159 weighted admissions (1.31 per 100,000) for NTMCL in 2016 and 2019 in the US, with the Midwest having the highest proportion of NTML-related admissions (1.59:100,000). NTMCL-related admissions were 2.21 times as likely to be elective rather than non-elective in the Midwest when compared to all other geographic regions (p = 0.038). The Midwest was 2.83 times as likely to treat with surgery (p = 0.011), while the Northeast was negatively associated with performing procedures (OR 0.38; p = 0.026). In the Midwest, significantly more excisional surgeries were preformed when compared to other regions, with an OR of 2.98 (p = 0.003). CONCLUSION The Midwest had the highest incidence of pediatric NTMCL-related admissions and was more likely to perform excisional surgery as primary NTMCL treatment. Regions that rarely see pediatric NTMCL have a more inconsistent approach to management.

Int J Pediatr Otorhinolaryngol 2024; 182:112019. [PMID: 38944979 DOI: 10.1016/j.ijporl.2024.112019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 06/16/2024] [Accepted: 06/19/2024] [Indexed: 07/02/2024]
Abstract
OBJECTIVE Cervicofacial lymphadenitis caused by non-tubercular mycobacterial (NTM) infections has the highest infection rate in children. Our objective was to assess patient demographics, treatment methods, and the impact of weather and geography on the incidence of disease in patients with NTM cervicofacial lymphadenitis. METHODS The Pediatric Health Information System (PHIS) database was queried for data on all patients diagnosed with concurrent cervicofacial lymphadenopathy and NTM infection from 2004 to 2022. We assessed the association between weather patterns and NTM cervicofacial lymphadenitis by collecting monthly weather data from the NOAA National Center for Environmental Information. Incidence rates were calculated by dividing the number of cases by the total hospital discharges during the study period. RESULTS Among 47 PHIS hospitals, there were 992 diagnoses of NTM cervicofacial lymphadenitis. The average age at diagnosis was 2 [IQR, 2-4], with 59 % female. Drainage of skin abscesses or lesions was performed for 93 (9.4 %) patients, while 15 (1.5 %) had an excisional procedure of the CPT codes assessed. The most common antibiotics utilized were cephalosporins (28 %), macrolides (27 %), and rifampin (12 %). The most common treatment method was surgery with antibiotics (37 %) followed by no treatment at all (35 %), surgery alone (17 %), and antibiotics alone (10 %). Of the 28 states included in the analysis, Washington (IR: 3.5) and Nebraska (IR: 3.3) had the highest incidence rates (IR) of NTM cervical lymphadenitis. The cases were relatively equally distributed across the different weather seasons within each U.S. geographic region. However, the overall average wind speed was weakly associated with increasing the risk of diagnosis when utilizing a mixed effect zero-inflated negative binomial model (Incidence Ratio: 1.07, 95 % CI: (1.01-1.14), p = 0.035). CONCLUSIONS Our results indicate that the most common treatment method utilized in patients within our cohort with NTM cervicofacial lymphadenitis was the concurrent use of surgery and antibiotics. Our results also indicate there may be variation in the incidence rate among different states, but additional studies are needed as our cohort only included approximately 50 % of states within the U.S.

Abstract
Background The prevalence of nontuberculous mycobacterial (NTM) disease in children is increasing worldwide. The clinical manifestations of pediatric NTM patients are significantly different from those of adult patients, but the knowledge of the disease is generally poor. Methods English databases (PubMed, Web of Science, Embase, BIOSIS) and Chinese databases (CNKI, Wanfan, VIP) were searched on October 15th, 2022. All the articles of cross-sectional and cohort studies reporting the species composition and lesion site of the NTM disease in children using well-recognized NTM species identification methods were taken into account. Using a random effects model, we assessed the disease lesion sites and the prevalence of different NTM species in pediatric NTM disease. Sources of heterogeneity were analyzed using Cochran's Q and the I2 statistic. All analyses were performed using CMA V3.0. Results The prevalence rates of NTM disease in children ranged between 0.6 and 5.36/100,000 in different countries, and Europe reported the highest prevalence rate. The most common clinical lesion site was lymph node, accounting for 71.1 % (55.0 %-83.2 %), followed by lung (19.3 %, 9.8%-34.4 %)and then skin and soft tissue (16.6 %,13.5%-20.3 %). Mycobacterium avium complex (MAC) was the most isolated NTM pathogen in children, accounting for 54.9 % (39.4%-69.6 %). Inconsistent with adult patients, Mycobacterium avium accounted for a dominant proportion in MAC than Mycobacterium intracellulare. Conclusions The lymph node was the most affected organ in pediatric NTM disease, while Mycobacterium avium was the most isolated pathogenic species in children.

Abstract
BACKGROUND Nontuberculous mycobacterial cervicofacial lymphadenitis (NTMCL) is an uncommon condition detected in young immunocompetent children who typically present with a nontender neck mass. Various tests have been proposed to assist in the work-up of suspected NTMCL, with varying diagnostic utility. This systematic review investigates the sensitivity of the various diagnostic methods used in the work-up of pediatric NTMCL. METHODS A systematic review in accordance with PRISMA guidelines was performed using the Pubmed, EMBASE, and Web of Science databases. Searches were filtered for English language studies published prior to 05/10/22. Studies meeting criteria included studies featuring 15+ pediatric patients with confirmed or suspected NTMCL. Studies with any reported diagnostic methodology used in the workup of NTMCL were included. RESULTS Of 836 abstracts/articles reviewed, 21 studies met inclusion criteria. Diagnostic methods included culture(n = 11 studies), PPD-Tb(Tuberculin)(n = 12), PPD-Scrofulaceum, -Avium, or -Kansasii(n = 6), staining techniques(n = 4), IGRA(n = 3), and ultrasound(n = 2). All studies had an overall low risk of bias. Among patients confirmed to have NTMCL based on PCR and/or culture, the most sensitive tests were PPD-A(0.94, 95 % CI 0.91 to 0.97; n = 210 patients) and PPD-S(0.75, 95 % CI 0.68 to 0.81; n = 171). Auramine and Ziehl-Neelsen staining techniques had moderately high sensitivity(0.85 and 0.60 respectively), though were limited by low patient numbers(n = 20). PPD-Tb(0.45, 95 % CI 0.39 to 0.50; n = 300) and IGRA(0.02; 95 % CI 0 to 0.06; n = 48) demonstrated poor sensitivity. Among patients suspected to have NTM lymphadenitis based on global assessment, the most sensitive tests included combined PPD-S + A + K(0.92, 95 % CI 0.86 to 0.98; n = 85), PCR(0.82, 95 % CI 0.75 to 0.88; n = 136), and PPD-A(0.72, 95 % CI 0.62 to 0.81; n = 84). Culture showed a sensitivity of 0.54(95 % CI 0.50 to 0.58; n = 494). PPD-K, PPD-S, IGRA, and staining techniques demonstrated lower sensitivity. CONCLUSIONS This systematic review is the largest study investigating the sensitivity of the various diagnostic methods used in the work-up of pediatric NTMCL. Patients with clinical suspicion for NTMCL and a positive PPD-Tb should first have tuberculous lymphadenitis ruled out with IGRA. Patients with a positive PPD-Tb and negative IGRA and high clinical suspicion for NTMCL can undergo presumptive surgical intervention. Patients with a negative PPD-Tb can undergo NTM antigen skin testing if available, or if high clinical suspicion exists, surgical intervention to reduce tissue burden and elicit additional tissue data.

Abstract
PURPOSE OF REVIEW The purpose of this review is to analyze and consolidate recently published literature to provide updated guidelines on the diagnosis and management of nontuberculous mycobacterial lymphadenitis (NTM LAD) in the pediatric population and to suggest areas of further research. RECENT FINDINGS Diagnosis of NTM LAD relies on a detailed clinical history, physical examination, laboratory tests, and imaging techniques. Treatment strategies vary widely, with a shift towards complete surgical excision being observed due to its higher cure rate, improved aesthetic outcomes, and lower recurrence rates. However, patient-specific factors must be considered. The role of genetic factors, such as Mendelian susceptibility to mycobacterial disease (MSMD), is being increasingly recognized and could lead to targeted therapies. SUMMARY Despite strides in the understanding and management of NTM LAD, substantial gaps remain in key areas such as the role of diagnostic imaging, optimal treatment parameters, postoperative care, and surveillance strategies. In this article, we explain our approach to NTM using the most relevant evidence-based medicine while offering directions for future work.

Abstract
The diseases caused by Non-tuberculous mycobacteria (NTM) has increased steadily in the last two decades. Increase in incidence of NTM infections are being reported in elderly people as they are more susceptible and often experiencing high morbidity. There is prediction that NTM infections will further rise because of expected increase in elderly population by 2050. Given the importance of NTM infection in the elderly, the interest in studying NTM characteristics in the aged population is increasing. In this review, we summarize the characteristics of NTM infection among elderly patients. We focus on epidemiology, clinical presentation, and treatment options of NTM in this age group. We highlight the differences in the diagnosis and treatment between rapid and slow growing mycobacterial infections. The current recommendations for treatment of NTM have been discussed. Finally, we have reviewed the prognosis of NTM disease in elderly patients.

Abstract
The spread of opportunistic pathogens via building water supply and plumbing is of public health concern. This study was conducted to better understand microbial water quality changes in a LEED-certified school building during low water use (Summer) and normal water use (Autumn). The copper plumbed building contained water saving devices, a hot water recirculation system, and received chloraminated drinking water from a public water system. Three separate sampling events were conducted during the summer break inside the building and another three sampling events were conducted after the school returned to session. Using quantitative PCR, Legionella spp. were detected in all water samples, followed by Mycobacterium spp. (99%). Mycobacterium avium (75%) and Acanthamoeba spp. (17.5%) throughout the building water system. Legionella pneumophila and Naegleria fowleri were not detected in any of the samples. The mean concentrations of Legionella spp., Mycobacterium spp., Mycobacterium avium, and Acanthamoeba spp. detected in water samples were 3.9, 5.7, 4.7, and 2.8 log10 gene copies per 100 ml, respectively. There was a statistically significantly difference in the mean concentrations of Legionella spp., Mycobacterium spp. and M. avium gene markers in water samples between school breaks and when school was in session. Cultivable Legionella were also detected in water samples collected during periods of low water use. This study highlights the need for routine proactive water quality testing in school buildings to determine the extent of drinking water quality problems associated with plumbing and direct action to remediate microbial colonization.

Abstract
OBJECTIVE Non-tuberculous mycobacteria (NTM) represents an important etiology of cervicofacial lymphadenitis (CFL) and skin/soft tissue infections in children. It can also affect the salivary glands, including the parotid gland, which is unique due to the presence of intra-salivary lymph nodes. There are no established guidelines for treatment of NTM CFL. NTM lymphadenitis was historically surgically treated; recently the literature supports initial medical treatment. Treatment decisions have been dependent on the extent of disease, preference of providers, and risk of surgical complications. The goal is to report our experience in surgical outcomes of NTM CFL with involvement of the parotid gland after pre-operative medical management. METHODS A retrospective case series of patients with NTM affecting the parotid gland at a tertiary care pediatric hospital between 2004 and 2020. RESULTS Seventy-two patients were referred for surgical evaluation of possible parotid NTM. Thirty-three patients underwent surgical excision. Fifteen patients were identified with presumed NTM infection involving the parotid gland. There were twelve females and three males with a mean age of 2.0 years (SD 1.55; range 1-6 days) at the time of surgery. All underwent surgical excision with parotidectomy. The most common pre-operative antimycobacterial therapy used was a combination of clarithromycin and rifampin. All 15 patients had pathological findings consistent with NTM infection (granulomatous lymphadenitis). Forty percent (n = 6) of patients had positive stains with acid-fast bacilli (AFB), with Mycobacterium avium as the most common species (n = 5). The majority of patients, 86.67% (n = 13), had complete resolution of infection after surgery. Clarithromycin and rifampin were the most common post-operative antimycobacterial treatment (mean 81.5 days, SD 110.14, range 2-411 days). The most common complication experienced was acute (<3 months) lower facial nerve paresis (40%, n = 6), but no patient had permanent facial paralysis. CONCLUSION AND RELEVANCE Parotidectomy is a safe and efficacious treatment in patients with NTM CFL affecting the parotid gland after incomplete resolution with antimycobacterial therapy. Further investigation to optimize duration of antimycobacterial treatment is necessary. We highlight the experience of a high-volume tertiary care pediatric hospital with surgical management of this disease.

J Oral Maxillofac Surg 2021; 80:537-544. [PMID: 34758350 DOI: 10.1016/j.joms.2021.09.029] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 09/24/2021] [Accepted: 09/27/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE Information on long-term treatment outcome for nontuberculous mycobacterial (NTM) cervicofacial lymphadenitis in children is scarce. The purpose of this study is to evaluate long-term outcome for surgical treatment, which is the mainstay treatment modality. METHODS This case series describes recurrence rates of surgically treated NTM cervicofacial lymphadenitis patients with a follow-up of at least 10 years. The current study data were partially collected from a randomized, prospective, multicenter, multidisciplinary trial (CHIMED study), which was conducted between 2000 and 2006 to determine the optimal treatment for NTM cervicofacial lymphadenitis in children. After the CHIMED trial inclusion ended, our institute continued to serve as a referral center. This enabled us to enlarge the surgical CHIMED cohort by adding patients who were treated during 2007 to 2010 in our center and collect the rest of the current study data. RESULTS About 427 children with chronic cervicofacial lymphadenopathy were analyzed. Among these, 290 had microbiologically confirmed cervicofacial mycobacterial infections (n = 3 Mycobacterium tuberculosis, n = 1 Mycobacterium bovis, n = 286 NTM). Of these 286 children with NTM cervicofacial lymphadenitis, 189 were treated surgically (median age: 41 months, range: 9-144, 46.0% males). The affected lymph nodes were excised in 151 children (79.9%), and curettage was performed in 38 children (20.1%). One patient (0.07%) experienced a reactivation/recurrence 2 years after surgical excision and required another surgical excision. Three children (7.9%) experienced infection reactivation/recurrences after curettage, confirmed by redness or a draining fistula, within the first year after healing. Two of these 3 patients were treated with additional surgical excisions. CONCLUSION The long-term outcome of surgical excision for NTM cervicofacial lymphadenitis is favorable with a low recurrence rate. Curettage or a conservative wait-and-see approach can be considered an alternative in advanced and surgically challenging cases. However, healing will take longer, and late recurrences are possible.

Abstract
Lymphadenopathy is an irregularity in the size and texture of the lymph nodes, which is quite common in childhood. When the enlargement of lymph nodes is caused by inflammatory and infectious processes, it is called lymphadenitis. The main objective of this manuscript is to summarize the common infectious etiologies and presentations of lymphadenitis in children providing a management guide for clinical practice. PubMed was used to search for all of the studies published up to April 2021 using keywords such as "lymphadenitis" and "children". Literature analysis showed that the differential diagnosis for lymphadenitis in pediatrics is broad. Although lymph node enlargement in children is usually benign and self-limited, it is important to exclude malignant etiology. In most cases, history and physical examination allow to identify the correct diagnosis and start a proper treatment with a prompt resolution of the lymphadenopathy. However, particularly in the case of persistent lymphadenitis, determining the cause of lymph node enlargement may be difficult, and the exact etiology may not be identified despite extensive investigations. Further studies should develop and validate an algorithm to assist pediatricians in the diagnosis and timely treatment of lymphadenitis, suggesting situations in which a watchful waiting may be considered a safe approach, those in which empiric antibiotic therapy should be administered, and those requiring a timely diagnostic work-up.

Abstract
OBJECTIVES To assess the performance of interferon-gamma release assays (IGRAs) in the differential diagnosis between Mycobacterium avium complex (MAC) and tuberculosis (TB) in children affected with subacute/chronic submandibular/cervical lymphadenitis. STUDY DESIGN Multicenter observational study comparing children with microbiologically confirmed MAC lymphadenitis from the European NontuberculouS MycoBacterial Lymphadenitis in childrEn study with children with TB lymphadenitis from the Spanish Network for the Study of Pediatric TB database. RESULTS Overall, 78 patients with MAC and 34 with TB lymphadenitis were included. Among MAC cases, 44 out of 74 (59.5%) had positive tuberculin skin test (TST) results at the 5-mm cut-off, compared with 32 out of 33 (97%) TB cases (P < .001); at the 10-mm cut-off TST results were positive in 23 out of 74 (31.1%) vs 26 out of 31 (83.9%), respectively (P < .001). IGRA results were positive in only 1 out of 32 (3.1%) patients with MAC who had undergone IGRA testing, compared with 21 out of 23 (91.3%) TB cases (P < .001). Agreement between TST and IGRA results was poor in MAC (23.3%; κ = 0.017), but good in TB cases (95.6%; κ = 0.646). IGRAs had a specificity of 96.9% (95% CI 84.3%-99.8%), positive predictive value of 95.4% (95% CI 78.2%-99.8%), and negative predictive value of 93.9% (95% CI 80.4%-98.9%) for TB lymphadenitis. CONCLUSIONS In contrast to TST, IGRAs have high specificity, negative predictive value, and positive predictive value for TB lymphadenitis in children with subacute/chronic lymphadenopathy, and consequently can help to discriminate between TB and MAC disease. Therefore, IGRAs are useful tools in the diagnostic work-up of children with lymphadenopathy, particularly when culture and polymerase chain reaction results are negative.

Abstract
Nontuberculous mycobacteria (NTM) are an emerging cause of infections, including chronic lymphadenitis in children. 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. We assessed lifestyle factors but did not identify specific risk behaviors. We noted that more cases of NTM lymphadenitis occurred during cold months than during warm months. Moreover, we noted female sex and age <5.5 years as potential risk factors. Complete extirpation of the affected lymph node appeared to be the best therapeutic measure. We integrated the study data to develop a simple risk score to predict unfavorable clinical outcomes for NTM lymphadenitis.

Abstract
OBJECTIVE Chronic cervicofacial lymphadenitis in children is often caused by nontuberculous mycobacteria (NTM). Children with NTM infection who were not surgically treated were evaluated for long-term outcome with a follow-up of at least 10 years. RESULTS Among the 117 nonsurgically treated children, the median age was 46 months (range, 9-155 months), 56 were male (47.9%), and 61 were female (52.1%). Of the overall group, 75 received antibiotic therapy consisting of clarithromycin and rifabutin (64.1%), and for 54, observation (a wait-and-see approach) was chosen (46.2%). In 100 patients, treatment was considered successful (85%), with a median resolution of 24 (range, 11-134) weeks in the antibiotic group compared to 44.5 (range, 18-130) weeks in the wait-and-see group (P < .05). After 6 months, 58 patients in the antibiotic group were successfully treated (77%), whereas 42 patients of the wait-and-see group demonstrated complete resolution after a median observation time of 44.5 weeks (100%). In 10 patients who experienced complete resolution of the lymphadenitis, infection recurrence developed years later (10%). CONCLUSION Nonsurgical treatment of NTM infection can be considered an alternative in advanced and surgically challenging cases. However, healing will take months to years, and late recurrences are possible.

Abstract
AIM Comparision of the incidence of cervical lymphadenitis caused by nontuberculous mycobacteria in two equal time periods before and after the ending of widespread calmetization (tuberculosis vaccination). Backgroung. From 2011 to 2018, 89 children were registered in the Tuberculosis Register with cervical lymphadenitis caused by nontuberculous mycobacteria, as confirmed by cultivation. In the majority of cases, the infection was caused by a mycobacterium belonging to the Mycobacterium avium complex. Only 7 cases of cervical lymphadenitis of the same etiology were registered during the same time interval between 2003 and 2010. The authors consider the ending of widespread calmetization (tuberculosis vaccination) in 2010 to be the main cause of the growing incidence. METHOD A comparison of data for the period 2003-2018 about cases of the illness caused by atypical mycobacteria as reported in the Tuberculosis Register. RESULTS The average incidence per year in the first interval was 0.04/100 000 children and in the second interval 0.53/100 000 children. During the second time interval, there was an increase from 0.14/100 000 children in 2011 to 1.40/100 000 children in 2018. While the incidence during the first time interval did not show any time trend (P=0.885), the year 2010 marks a significant turning point, with growth during the second interval being highly statistically significant (P<0.001).

Abstract
Cold abscess is an abscess without local pain and warmth and it usually accompanies Tuberculosis. The site varied depending upon the organ affected and cervical region is the commonly affected one. Cyto-morphology of cold abscess usually showed caseation type of necrosis, lymphocytes and granuloma with degenerated epithelioid cells. Here we presented an inguinal cold abscess in 9 years old girl with unique cyto-morphology of plenty of neutrophils, foam cells and lymphocytes in fine needle aspiration smear without caseation necrosis and epithelioid cells. Presence of Mycobacterium in the aspirated pus was proved by Ziehl-Neelsen as well as Auramine fluorescent staining. This characteristic cyto-morphology of mycobacterium infection mimicking pyogenic abscess emphasizes the importance of Ziehl-Neelsen staining in all abscess for early specific diagnosis and effective treatment.

Abstract
Background The prevalence of infections due to nontuberculous mycobacteria (NTM) is increasing worldwide, yet little is known about the epidemiology and pathophysiology of these ubiquitous environmental organisms. Pulmonary disease due to Mycobacterium avium complex is most prevalent, but many other NTM species can cause disease in virtually any organ system. As NTM becomes an increasingly common cause of morbidity and mortality, more information is needed about the epidemiology of NTM disease. Methods We conducted a retrospective chart review of all patients with cultures that grew NTM at a Midwestern tertiary hospital from 1996 to 2017. Information on demographics, medical history, clinical findings, treatment, and outcome was obtained from medical records of all NTM isolates. American Thoracic Society/Infectious Diseases Society of America criteria were used to define pulmonary NTM infections. Results We identified 1064 NTM isolates, 365 of which met criteria for NTM infection. Pulmonary cases predominated (185 of 365; 50.7%), followed by skin/soft tissue (56 of 365; 15.3%), disseminated (40 of 365; 11%), and lymphatic (28 of 365; 7.7%) disease. Mycobacterium avium complex was the most common species (184 of 365; 50.4%). Individuals aged >50 years were most affected (207 of 365; 56.7%). Common comorbidities included structural lung disease (116 of 365; 31.8%), use of immunosuppressive medications (78 of 365; 21.4%), malignancy (59 of 365; 16.2%), and human immunodeficiency virus (42 of 365; 11.5%). Conclusions This large cohort provides information on the demographics, risk factors, and disease course of patients with pulmonary and extrapulmonary NTM infections. Most patients had medical comorbidities that resulted in anatomic, genetic, or immunologic risk factors for NTM infection. Further population-based studies and increased disease surveillance are warranted to further characterize NTM infection prevalence and trends.

Cervicofacial non-tuberculous mycobacterial lymphadenitis: clinical determinants of incomplete surgical removal. Int J Oral Maxillofac Surg 2020; 49:1392-1396. [PMID: 32371179 DOI: 10.1016/j.ijom.2020.03.019] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Revised: 02/10/2020] [Accepted: 03/31/2020] [Indexed: 10/24/2022]
Abstract
In patients with non-tuberculous mycobacterial cervicofacial lymphadenitis, incomplete surgical removal of infected lymph nodes leads to delayed healing and a higher recurrence rate, with eventual spontaneous drainage through the skin. However, complete surgical removal is not always achievable due to the extent of the infected tissue and proximity to vulnerable structures, such as the facial or accessory nerve. The aim of this study was to identify the clinical determinants of the (in)ability to perform complete surgical removal. The electronic health records of patients aged 0-15 years with bacteriologically proven non-tuberculous mycobacterial cervicofacial lymphadenitis, who underwent surgical treatment and preoperative sonographic imaging, were analysed. This was a case-control study. A total of 103 patients met the inclusion criteria. Most of the infections were unilateral, submandibular, and caused by Mycobacterium avium. Multiple logistic regression analysis revealed that higher age (odds ratio 1.24, 95% confidence interval 1.04-1.47) and fistulization (odds ratio 3.15, 95% confidence interval 1.13-8.75) were significantly associated with a limited ability to surgically remove all infected tissue. However, a larger sonographic lymph node size was not significantly associated. These findings could aid clinicians when informing the parent(s)/guardian(s) of the patient preoperatively and in properly estimating the intraoperative and postoperative course.

Abstract
The aim of this study was to describe the frequency of nontuberculous mycobacteria (NTM) isolation and their related outcomes among pediatric patients of a Brazilian university hospital from 2012 to 2019. NTM were identified in different clinical samples by microbiological culture and molecular-based methods. NTM were isolated from 14 patients, out of whom four (27%) were infected and were treated accordingly. Two were infected with Mycobacterium avium complex (MAC), two with M. abscessus complex (MABSC) and one with M. intracellulare. Two patients had cystic fibrosis-related lung disease and improved after successful NTM eradication. One patient was HIV-positive and died. One patient had severe combined immunodeficiency (SCID)-related pneumonia and is currently being followed-up. We conclude that NTM frequency in our center was low among pediatric patients. Whether this is inherent to Brazilian patients, due to the broad coverage of the Bacille Calmette-Guérin (BCG) vaccine in Brazil, or a result of underdiagnosis remains to be elucidated.

Abstract
Background Epidemiological data on childhood nontuberculous mycobacterial (NTM) disease is scarce and the protective effect of bacille Calmette-Guérin (BCG) vaccination remains debated. In 2006, the BCG policy in Finland changed from universal to selective. We aimed to study the effect of the BCG coverage decrease on the incidence of childhood NTM infections in Finland. Methods We conducted a nationwide, population-based, retrospective study of NTM notifications recorded to the National Infectious Diseases Register between 1995 and 2016 and identified native-born children aged 0-4 years infected with NTM. Poisson log-linear model was used to estimate the change in the incidence rate of cohorts born during universal or selective BCG policy between 1995 and 2015. Results We identified 97 native-born children aged <5 years infected with NTM (median age, 27 months; female-to-male ratio, 2:1). The most common species was Mycobacterium avium (n = 69 [71%]). The estimated incidence rates of NTM in universal-BCG and selective-BCG cohorts were 0.2 and 3.9 per 100000 person-years, respectively. The incidence rate ratio of selective-BCG cohorts compared to universal-BCG cohorts was 19.03 (95% confidence interval, 8.82-41.07; P < .001). Conclusions After infant BCG coverage in Finland decreased, childhood NTM infections increased drastically. As there is no other apparent cause for the increase, this indicates that BCG offers protection against childhood NTM disease. This observation adds to the understanding of childhood NTM epidemiology and might explain why the disease is emerging in some countries.

Abstract
Nontuberculous mycobacteria (NTM) infect children with increasing frequency worldwide. Using blood and lymph node tissue from children with NTM lymphadenitis, and uninfected lymph node tissue from community controls, we evaluated helper T (TH) cells in functional assays of TH1/TH17 differentiation and measured the concentration of their associated cytokines at the site of infection. Circulating TH cells from infected children were attenuated in their TH1/TH17 differentiation capacity and expressed less interferon γ and interleukin 17 after polyclonal stimulation. Similar differences were observed at the site of infection, where most cytokine concentrations were unchanged relative to controls. Our data are consistent with a model wherein TH1/TH17 differentiation is attenuated in NTM-infected children.

Abstract
Non-tuberculous mycobacteria (NTM) are ubiquitous environmental bacteria that can induce pulmonary and non-pulmonary diseases in susceptible persons. It is reported that the prevalence of NTM diseases is increasing in developed countries, but this differs by regions and countries. NTM species distribution and the rate of diseases caused by NTM vary widely in the historical territories of Moravia and Silesia (Czech Republic). This epidemiologic study of NTM diseases covers the period 2012–2018, reviews isolates obtained from patients with clinical disease and investigates correlations with related socio-economic and environmental factors. Individual NTM patients were included only once during the studied period and results were presented as incidence rate per year. The most frequently isolated NTM meeting the microbiological and clinical criteria in the study were the Mycobacterium avium-intracellulare complex, followed by Mycobacterium kansasii and Mycobacteriumxenopi. A previously described endemic incidence of M.kansasii in the Karviná district and M.xenopi in the Ostrava district was also observed in this study. The incidence of NTM patients in the whole studied territory was 1.10/100,000 inhabitants (1.33/100,000 in men and 0.88/100,000 in women). The annual incidence of lymphadenitis in children (≤5 years of age) was 2.35/100,000 of the population of children during the 7 year period but increased in the year 2018 to 5.95/100,000. The rate of human tuberculosis in the studied area was 1.97/100,000 inhabitants. The incidence of NTM pulmonary diseases correlated with a lower socio-economic status (r = 0.63) and a higher concentration of benzo[a]pyrene pollution in the air (r = 0.64).

Abstract
Background The incidence of nontuberculous mycobacterial (NTM) infections is increasing worldwide, particularly NTM lymphadenitis and skin infections (Buruli ulcer). This review summarizes the evidence for the protective effectiveness of BCG vaccination against NTM disease. Methods A systematic search using PRISMA guidelines was done for controlled studies investigating the protective effectiveness of BCG vaccination against NTM disease in immunocompetent individuals. This revealed 10 studies, including almost 12 million participants. Results Three cohort studies in industrialized countries suggest that the incidence of NTM lymphadenitis is greatly reduced among BCG-vaccinated children compared with BCG-unvaccinated children, with a risk ratio (RR) of 0.04 (95% confidence interval [CI], .01-.21). In two randomized trials in low-income countries, BCG protected against Buruli ulcer for the first 12 months following vaccination (RR, 0.50 [95% CI, .37-.69]). Four case-control studies had conflicting results. One cohort study found that individuals with Buruli ulcer are less likely to develop osteomyelitis if they have a BCG scar (RR, 0.36 [95% CI, .22-.58]). No studies have compared different BCG vaccine strains or the effect of revaccination in this setting. Conclusions The protective effect of BCG vaccination against NTM should be taken into consideration when deciding on recommendations for discontinuation of universal BCG vaccination programs and in assessing new vaccines designed to replace BCG.

Abstract
BACKGROUND Non-tuberculous mycobacteria (NTM) causing pulmonary and extra-pulmonary diseases are increasing worldwide. A large paucity of data related to pediatric NTM diseases exists globally and particularly in Saudi Arabia. METHODS The first nationwide exploratory study on existence of NTM diseases among Saudi Arabian children (0-14 years old) has been carried out during 2016-2017. Suspected NTM isolates with clinical and demographical data were enrolled from regional reference laboratories. Species level identification of isolates was carried out by commercial line probe assays and gene sequencing. RESULTS In 12 months, 52 culture positive cases with 44(84.6%) confirmed disease incidences were identified. Demographically, Saudi nationals (86.5%) were dominated and 77.3% cases have different comorbid conditions. Lymphadenitis (40.4%) followed by 26.9% of pulmonary cases with 42.8% of confirmed clinical relevance were mainly reported. Species identification showed Mycobacterium simiae (31.8%), M. abscessus (23.1%) and nine other species including rarely encountering M. riyadhense. Ascites caused by M. monacense, pulmonary disease caused by M. riyadhense and M. monacense were rarest clinical events and reported for the first time globally in a pediatric cohort. CONCLUSIONS Diverse NTM diseases even in immunocompetent children are an upcoming challenge in Saudi Arabia. Lack of awareness on NTM disease must be addressed with immediate development of management plans.

Abstract
Nontuberculous mycobacteria (NTM) diseases mainly manifest as pulmonary illnesses, but 20 -30% of NTM isolates originate from extrapulmonary diseases. These diseases cause a variety of clinical syndromes, including skin and soft-tissue infections, musculoskeletal infections, lymphadenitis, and disseminated disease. In skin and soft-tissue infections, musculoskeletal infections, prolonged treatment with combinations of antibiotics is effective in the treatment of NTM diseases, with surgery as an important complementary tool. The recommended duration of therapy for skin and soft-tissue infection is usually 2 – 4 months for mild disease and 6 months for severe disease, while treatment of musculoskeletal NTM disease usually requires at least 6 - 12 months. Management options of NTM lymphadenitis include surgical intervention, medical therapy, or observation. Treatment of disseminated NTM disease generally requires 6 to 12 months after immune restoration. However, despite a considerable increase in knowledge about NTM diseases, determining optimal treatment approaches remains a complex and challenging task.

Abstract
X-linked dominant incontinentia pigmenti (IP) and X-linked recessive anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID) are caused by loss-of-function and hypomorphic IKBKG (also known as NEMO) mutations, respectively. We describe a European mother with mild IP and a Japanese mother without IP, whose 3 boys with EDA-ID died from ID. We identify the same private variant in an intron of IKBKG, IVS4+866 C>T, which was inherited from and occurred de novo in the European mother and Japanese mother, respectively. This mutation creates a new splicing donor site, giving rise to a 44-nucleotide pseudoexon (PE) generating a frameshift. Its leakiness accounts for NF-κB activation being impaired but not abolished in the boys' cells. However, aberrant splicing rates differ between cell types, with WT NEMO mRNA and protein levels ranging from barely detectable in leukocytes to residual amounts in induced pluripotent stem cell-derived (iPSC-derived) macrophages, and higher levels in fibroblasts and iPSC-derived neuronal precursor cells. Finally, SRSF6 binds to the PE, facilitating its inclusion. Moreover, SRSF6 knockdown or CLK inhibition restores WT NEMO expression and function in mutant cells. A recurrent deep intronic splicing mutation in IKBKG underlies a purely quantitative NEMO defect in males that is most severe in leukocytes and can be rescued by the inhibition of SRSF6 or CLK.

Abstract
BACKGROUND Non-tuberculous mycobacteria (NTM) constitute an important cause of cervical lymphadenitis in immunocompetent children. 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. METHODS Children aged 1-5 years old, evaluated at Archbishop Makarios III Hospital, Nicosia, Cyprus, from 1 January 2007 to 31 December 2016 for lymphadenopathy, were included in the study. All children had positive lymph node culture for NTM. RESULTS A total of 22 cases of culture-positive lymphadenitis caused by NTM were reviewed. Patient age ranged from 16 to 55 months. Tuberculin skin test produced an induration in 81.0% of cases (diameter, 4-17 mm). Mycobacterium avium was isolated in 17 cases (77.3%), M. intracellulare in three (13.6%), M. paraffinicum in one (4.5%) and M. kansasii in one case (4.5%). All 22 patients underwent surgical excision of affected nodes. Additional anti-mycobacterial treatment was given when complete excision was not achieved or for post-surgical recurrence. Complications were few and included scar in three children and one case of transient facial nerve palsy. CONCLUSION Surgical excision of NTM-infected lymph nodes is an effective diagnostic and therapeutic approach. 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.

Int J Pediatr Otorhinolaryngol 2018; 112:48-54. [PMID: 30055739 DOI: 10.1016/j.ijporl.2018.06.034] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Revised: 06/14/2018] [Accepted: 06/15/2018] [Indexed: 10/28/2022]
Abstract
OBJECTIVES Widespread controversy exists regarding correct diagnosing nontuberculous mycobacterial cervicofacial (NTM) lymphadenitis. This study intends to gather the available evidence with respect to diagnosing NTM cervicofacial lymphadenitis. METHODS A review protocol was developed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)-statement (www.prisma-statement.org). A comprehensive search was performed in the bibliographic databases PubMed, Embase.com and Wiley/Cochrane Library. 10 Articles fulfilled the inclusion criteria and were included in the review. Assessing risk of bias of the articles was done using the revised Quality Assessment of Diagnostic Accuracy (QUADAS-2) tool. RESULTS This systematic review shows that diagnostic studies of high methodological quality are scarce. Diagnostic accuracy of polymerase chain reaction (PCR), culture, skin testing, auramine staining, Ziehl-Neelsen staining, and immunodiagnostic assays was studied. Culture sensitivity proved to be 41,8%, while polymerase chain reaction has a sensitivity of 71,6%. Both methods showed a specificity of 100%. Sensitivity of Immunodiagnostic assays ranged between 87,5% and 100% and specificity between 81% and 100%. Overall sensitivity of skin tests containing purified protein derivative (PPD-S) was 70% (95% CI [62%-78%]) with an overall specificity of 94% (95% CI [88%-100%]). CONCLUSIONS In patients with a high clinical suspicion for NTM cervicofacial lymphadenitis, a positive PPD-S skin is indicative for the diagnosis of NTM cervicofacial lymphadenitis. Either PCR or culture is necessary to confirm the diagnosis. Interferon-γ release assays with purified protein derivative stimulation appear to provide good sensitivity and specificity as a non-invasive pre-operative test, but the evidence is weak. More studies of high methodological quality are needed to validate the results of this systematic review.

Abstract
Salivary gland tumors and tumor-like lesions in the pediatric population are uncommon. They comprise a heterogeneous group of infectious/inflammatory and neoplastic conditions. Pediatric salivary neoplasms include benign tumors of mesenchymal or epithelial origin as well as malignancies of epithelial (carcinomas), mesenchymal (sarcoma) or hematolymphoid (lymphoma) derivation. Infectious/inflammatory conditions and hematolymphoid malignancies may represent either genuine parenchymal pathology or conditions involving intraglandular lymph nodes of the parotid glands (intraglandular lymphadenopathy and intraglandular nodal lymphomas). Pediatric sialadenitis may be of diverse etiologies including viral (mumps, CMV, HIV, etc.), bacterial, autoimmune (juvenile Sjögren syndrome) or idiopathic (chronic recurrent juvenile sialectatic sialadenitis). Angiomatous lesions (juvenile capillary hemangioma, lymphangioma and vascular malformation) and pleomorphic adenomas represent the most common pediatric benign mesenchymal and benign epithelial tumors, respectively. The vast majority of salivary gland carcinomas in children and adolescents represent low-grade mucoepidermoid carcinomas followed by acinic cell and adenoid cystic carcinomas (together >80% of carcinomas). Other malignant neoplasms include (rhabdomyo-) sarcomas, malignant lymphomas and very rarely sialoblastomas. This long differential diagnosis list of etiologically and biologically highly heterogeneous entities, their shared clinical presentation as "salivary gland enlargement" and the significant differences in their therapeutic strategies and prognosis underline the need for careful assessment to identify the correct diagnosis. Diagnosis is mainly based on a set of typical clinical and imaging features, serological/microbiological findings and, in selected cases, histomorphological characteristics in biopsy specimens.

Abstract
There is limited literature on Mycobacterium abscessus infections in children and limited data about its diagnosis and management. The incidence of infections due to M abscessus appears to be increasing in certain populations and can be a significant cause of morbidity and mortality.Management of these infections is challenging and relies on combination antimicrobial therapy and debridement of diseased tissue, depending on the site and extent of disease. Treatment regimens often are difficult to tolerate, and the antimicrobials used can cause significant adverse effects, particularly given the long duration of therapy needed.This review summarizes the literature and includes information from our own institution's experience on pediatric M abscessus infections including the epidemiology, transmission, clinical manifestations, and the management of these infections. Adult data have been used where there are limited pediatric data. Further studies regarding epidemiology and risk factors, clinical presentation, optimal treatment, and outcomes in children are necessary.

Abstract
Recent studies suggest that the incidence of nontuberculous mycobacterial infections in children may be increasing. Nontuberculous mycobacterial lymphadenitis, skin and soft tissue infection, and pulmonary disease each present unique challenges in relation to diagnosis and treatment. In this update, we critically review the recent literature on the epidemiology, clinical features, diagnostic approaches and treatment of nontuberculous mycobacterial disease in children. In addition, we outline key areas warranting further research.

Abstract
A quantitative microbial risk assessment (QMRA) of opportunistic pathogens Legionella pneumophila (LP) and Mycobacterium avium complex (MAC) was undertaken for various uses of roof-harvested rainwater (RHRW) reported in Queensland, Australia to identify appropriate usages and guide risk management practices. Risks from inhalation of aerosols due to showering, swimming in pools topped up with RHRW, use of a garden hose, car washing, and toilet flushing with RHRW were considered for LP while both ingestion (drinking, produce consumption, and accidental ingestion from various activities) and inhalation risks were considered for MAC. The drinking water route of exposure presented the greatest risks due to cervical lymphadenitis and disseminated infection health endpoints for children and immune-compromised populations, respectively. It is therefore not recommended that these populations consume untreated rainwater. LP risks were up to 6 orders of magnitude higher than MAC risks for the inhalation route of exposure for all scenarios. Both inhalation and ingestion QMRA simulations support that while drinking, showering, and garden hosing with RHRW may present the highest risks, car washing and clothes washing could constitute appropriate uses of RHRW for all populations, and toilet flushing and consumption of lettuce irrigation with RHRW would be appropriate for non- immune-compromised populations.

Abstract
Disease caused by nontuberculous mycobacteria (NTM) is reported to increase due to an ageing population and a rise in the proportion of immunosuppressed patients. We did a retrospective cohort study of NTM-disease in the Danish population through a quarter-century to determine the disease burden and trends in annual incidence rates. 524,119 clinical specimens were cultured for mycobacteria from 1991 through 2015 at the International Reference Laboratory of Mycobacteriology in Denmark. Among these, 8,227 NTM strains were identified from 3,462 patients and distributed according to microbiological disease criteria. We observed no increase in NTM disease incidence or proportion of patients with positive NTM cultures during the study period (Quasi-Poisson regression, p = 0.275 and 0.352 respectively). Annual incidence rates were 1.20/105 for definite NTM disease, 0.49/105 for possible NTM disease and 0.88/105 for NTM colonization. The incidence rate of NTM disease was highest in children aged 0-4 years (5.36/105/year), predominantly with cervical Mycobacterium avium complex (MAC) adenitis. Surprisingly, based on more than half a million clinical specimens cultured for mycobacteria in Denmark through 25 years, the NTM disease burden and trend in incidence in the Danish population has not increased opposed to numerous internationals reports.

Abstract
Despite the ubiqitous nature of Mycobacterium avium complex (MAC) organisms in the environment, relatively few of those who are infected develop disease. Thus, some degree of susceptibility due to either underlying lung disease or immunosuppression is required. The frequency of pulmonary MAC disease is increasing in many areas, and the exact reasons are unknown. Isolation of MAC from a respiratory specimen does not necessarily mean that treatment is required, as the decision to treatment requires the synthesis of clinical, radiographic, and microbiologic information as well as a weighing of the risks and benefits for the individual patient. Successful treatment requires a multipronged approach that includes antibiotics, aggressive pulmonary hygiene, and sometimes resection of the diseased lung. A combination of azithromycin, rifampin, and ethambutol administered three times weekly is recommend for nodular bronchiectatic disease, whereas the same regimen may be used for cavitary disease but administered daily and often with inclusion of a parenteral aminoglycoside. Disseminated MAC (DMAC) is almost exclusively seen in patients with late-stage AIDS and can be treated with a macrolide in combination with ethambutol, with or without rifabutin: the most important intervention in this setting is to gain HIV control with the use of potent antiretroviral therapy. Treatment outcomes for many patients with MAC disease remain suboptimal, so new drugs and treatment regimens are greatly needed. Given the high rate of reinfection after cure, one of the greatest needs is a better understanding of where infection occurs and how this can be prevented.

Abstract
Mycobacterium avium hominissuis is the most important causative agent of chronic nontuberculous lymphadenitis in children. Despite a ubiquitous occurrence of the bacteria in the environment, the disease is a rare entity, and so far no source of infection has been formally identified. The current state of knowledge regarding possible sources of M. avium hominissuis, especially where children are concerned, is summarized here. An analysis of the seasonal variation of M. avium lymphadenitis in children leads to a new hypothesis regarding the probable source of infection of M. avium hominissuis, where global trade of alimentary products might be involved.

Abstract
PURPOSE Nontuberculous mycobacteria are uncommon cause of chronic cervicofacial lymphadenitis in healthy children. We describe clinical features and management strategies of cervicofacial nontuberculous mycobacterium lymphadenitis in a tertiary pediatric hospital. METHODS Retrospective analysis of medical records of children discharged from 1992 to 2014 with a diagnosis of cervicofacial nontuberculous mycobacterium was made. Diagnosis certainty was based on microhistological investigations. Clinical stage was evaluated according to lymph node size and presence of fistulas. Successful therapy was defined by the regression of the lymph node enlargement (>75%) or complete surgical excision without relapse. RESULTS Cervicofacial nontuberculous mycobacterium was diagnosed in 33 patients. Complete excision was performed in 73% of cases primarily observed in our hospital, while 83% of those referred from other hospitals required further surgical treatment. No case of relapse was observed after one year of follow-up. CONCLUSIONS We recommend surgical approach as the first therapeutic option in the management of cervicofacial nontuberculous mycobacterium lymphadenitis. LEVELS OF EVIDENCE Prognosis and Retrospective Study - Level II.

Abstract
BACKGROUND Nontuberculous mycobacteria (NTM) are ubiquitous organisms with variable disease-causing potential. Bloodstream infections caused by NTM in children are poorly described. METHODS We describe a retrospective case series of children with culture-confirmed mycobacterial disease managed at the Children's Hospital at Westmead between July 2005 and June 2015. RESULTS Sixty-five patients had 149 positive NTM cultures; 55 (83.0%) episodes in 54 patients were considered clinically significant. Of the 54 children who met criteria for NTM disease, 25 (46.3%) had lymphadenitis, 13 (24.1%) lung disease, 8 (14.8%) had soft tissue infection or osteomyelitis and 8 (14.8%) had bacteremia. All children with bacteremia had a central venous catheter; those with pulmonary infection had underlying lung disease and all children with soft tissue infection or osteomyelitis had a history of recent penetrating injury. Disease caused by Mycobacterium avium-intracellulare complex was most common, accounting for 19 (76.0%) and 7 (53.8%) lymph node and lung infections, respectively. The most frequently isolated rapid growing mycobacteria were Mycobacterium fortuitum (8; 15%) and Mycobacterium abscessus (6; 11%), with M. fortuitum accounting for the majority (6; 75%) of bloodstream infections. Six (75%) patients with bacteremia had their intravenous catheter removed and all had a favorable outcome. A single disease relapse was reported in 1 of 2 patients with a retained catheter. CONCLUSION Lymphadenitis was the most common NTM disease manifestation and not associated with comorbidity. NTM bacteremia was always associated with a central line and catheter removal with cure. We were unable to assess the added value of various antibiotic regimens.

Abstract
Tropical skin diseases are infectious conditions influenced by factors such as nutrition, housing, and the environment. Migration patterns have caused these conditions to be seen all around the world, not only in developing countries. Many of these diseases have a different presentation in childhood, which changes the diagnostic approach and management options. In this article, we review some of the most common tropical mycobacterial, protozoan, parasitic, and viral dermatologic conditions in children, including their epidemiologic, clinical, diagnostic, and therapeutic aspects.

Abstract
OBJECTIVE To study the epidemiology, clinical features, diagnosis, therapeutic management, and outcome of non-tuberculous mycobacterial lymphadenitis in a paediatric population of Aragón (Spain). MATERIAL AND METHODS A retrospective study was conducted on patients under 15 years-old diagnosed with non-tuberculous mycobacterial lymphadenitis between the years 2000 and 2015. INCLUSION CRITERIA patients with lymphadenitis and positive culture. Quantitative values are shown as mean, rank, and standard deviation, and qualitative data as frequencies. RESULTS Twenty-seven cases were registered, with a mean age of presentation of 39.9 months (range 10 months-8 years). The mean time between the symptoms onset and first consultation was 1.7±1.1 months. The most frequent location was sub-maxilar in 17/27 cases (63%), on the right side in 59.3%, and size 2.96±1.26cm. Fistulae were observed in 16/27 cases. Tuberculin test was greater than 10mm in 7/24 (29.1%). Microbiological cultures were positive for Mycobacterium avium in 14/27 (51.9%), Mycobacterium intracellulare 3/27 (11.1%), and Mycobacterium lentiflavum 3/27 (11.1%). Combined treatment of antibiotics and surgery was given in 16/27 cases (59.8%), medical treatment only in7/27 (25.9%), and surgical exeresis alone in 4/27 (14.8%). Two patients required a new surgery, and one showed severe neutropenia secondary to rifabutin. Only one case (3.7%) suffered from temporary facial palsy as sequel. CONCLUSIONS The most frequent treatment was the combination of antibiotics and surgery. Delay in diagnosis seemed to be responsible for the limited number of exeresis as first option, only one for every seven patients.

Abstract
BACKGROUND Nontuberculous mycobacteria rarely cause facial skin lesions in immunocompetent children. AIM I describe the clinical features and treatment of nontuberculous mycobacteria facial lesions. MATERIALS AND METHODS The diagnosis of a facial nontuberculous mycobacteria infection was established using polymerase chain reaction. RESULTS Of 286 children with confirmed nontuberculous mycobacteria infection, 14 (4.9%; median age 50 mos, range 9-156 mos; 5 [36%] male, 9 [64%] female) had nontuberculous mycobacteria facial skin lesions. Six (43%) had lesions on the cheek and five (36%) in the medial eye corner. Polymerase chain reaction results confirmed the presence of Mycobacterium haemophilum in eight patients (57%) and Mycobacterium avium in six patients (43%). The facial lesions were treated using a combination of clarithromycin and rifabutin for 12 weeks, with a median healing time of 4 months. CONCLUSION Nontuberculous mycobacteria facial lesions are rare in immunocompetent children. The diagnosis requires a high index of suspicion. Nonsurgical treatment is preferable, because surgical excision of the cutaneous lesions might lead to undesirable visible facial scars.

Abstract
Background There are limited data on the epidemiology, diagnosis and optimal management of nontuberculous mycobacterial (NTM) disease in children. Methods Retrospective cohort study of NTM cases over a 10-year-period at a tertiary referral hospital in Australia. Results A total of 140 children with NTM disease, including 107 with lymphadenitis and 25 with skin and soft tissue infections (SSTIs), were identified. The estimated incidence of NTM disease was 0.6–1.6 cases / 100,000 children / year; no increasing trend was observed over the study period. Temporal analyses revealed a seasonal incidence cycle around 12 months, with peaks in late winter/spring and troughs in autumn. Mycobacterium-avium-complex accounted for most cases (77.8%), followed by Mycobacterium ulcerans (14.4%) and Mycobacterium marinum (3.3%). Polymerase chain reaction testing had higher sensitivity than culture and microscopy for acid-fast bacilli (92.0%, 67.2% and 35.7%, respectively). The majority of lymphadenitis cases underwent surgical excision (97.2%); multiple recurrences in this group were less common in cases treated with clarithromycin and rifampicin compared with clarithromycin alone or no anti-mycobacterial drugs (0% versus 7.1%; OR:0.73). SSTI recurrences were also less common in cases treated with two anti-mycobacterial drugs compared with one or none (10.5% versus 33.3%; OR:0.23). Conclusions There was seasonal variation in the incidence of NTM disease, analogous to recently published observations in tuberculosis, which have been linked to seasonal variation in vitamin D. Our finding that anti-mycobacterial combination therapy was associated with a reduced risk of recurrences in patients with NTM lymphadenitis or SSTI requires further confirmation in prospective trials.
