Abstract
BACKGROUND Systemic autoinflammatory disorders (SAIDs) represent a growing spectrum of diseases characterized by dysregulation of the innate immune system. The most common pediatric autoinflammatory fever syndrome, Periodic Fever, Aphthous Stomatitis, Pharyngitis, Adenitis (PFAPA), has well defined clinical diagnostic criteria, but there is a subset of patients who do not meet these criteria and are classified as undefined autoinflammatory diseases (uAID). This project, endorsed by PRES, supported by the EMERGE fellowship program, aimed to analyze the evolution of symptoms in recurrent fevers without molecular diagnosis in the context of undifferentiated AIDs, focusing on PFAPA and syndrome of undifferentiated recurrent fever (SURF), using data from European AID registries. METHODS Data of patients with PFAPA, SURF and uSAID were collected from 3 registries including detailed epidemiological, demographic and clinical data, results of the genetic testing and additional laboratory investigations with retrospective application of the modified Marshall and PRINTO/Eurofever classification criteria on the cohort of PFAPA patients and preliminary SURF criteria on uSAID/SURF patients. RESULTS Clinical presentation of PFAPA is variable and some patients did not fit the conventional PFAPA criteria and exhibit different symptoms. Some patients did not meet the criteria for either PFAPA or SURF, highlighting the heterogeneity within these groups. The study also explored potential overlaps between PFAPA and SURF/uAID, revealing that some patients exhibited symptoms characteristic of both conditions, emphasizing the need for more precise classification criteria. CONCLUSIONS Patients with recurrent fevers without molecular diagnoses represent a clinically heterogeneous group. Improved classification criteria are needed for both PFAPA and SURF/uAID to accurately identify and manage these patients, ultimately improving clinical outcomes.

Abstract
PURPOSE We aim to compare the different treatment modalities of non-tuberculous cervicofacial lymphadenitis in children, by means of a retrospective study conducted in the University Hospitals of Leuven of patients treated between 2012 and 2022. METHODS For this retrospective cohort study, data were collected and pseudonimised from 52 patients with non-tuberculous cervicofacial lymphadenitis, who were treated in our hospital between January 2012 and December 2022, either conservatively, antibiotically, surgically, or with a combination of these options. We only included patients who were considered immunocompetent. All of the included patients were below 10 years at time of treatment. We collected data regarding time to resolution and adverse effects, i.e., skin discoloration, excessive scar formation, fistula formation, persistence of adenopathies after treatment, need for additional treatment, facial nerve paresis/paralysis, or systemic side-effects due to antibiotic treatment. RESULTS The mean time to resolution (in days) when looking at primary treatments, was shortest in partial excisions (16), followed by complete excisions (19), antibiotic therapy (129), incision and drainage (153), curettage (240), and finally conservative management (280). Taking into account isolated treatments (i.e., both primary and adjuvant), we also observed consistently faster time to resolution in surgical and antibiotic treatments when compared to conservative treatment. Antibiotic therapy (p = 0.003), incision and drainage (p = 0,004) were associated with a significantly higher need for adjuvant treatment. Curettage was associated with a higher incidence of fistula formation (p = 0,006) and higher number of adjuvant treatments (p = 0,002). CONCLUSIONS This study shows a faster resolution of nontuberculous mycobacterial cervicofacial lymphadenitis in children when treated surgically, more specifically when treated with partial or complete lymph node excision. Antibiotic treatment also leads to faster resolution than conservative management. There was a low rate of complications, and no permanent facial nerve damage was reported.

Abstract
BACKGROUND Lymphadenitis is the most common manifestation of non-tuberculous mycobacteria (NTM) infection in children. We describe the epidemiology and clinical characteristics of NTM lymphadenitis, determine diagnostic yield from tissue sampling, and review management and outcomes. METHODS This was a 10-year retrospective review of children aged 0-16 years diagnosed with NTM cervicofacial lymphadenitis who were seen in a pediatric infectious disease clinic in a tertiary public hospital. Data relating to patient demographics, clinical features, surgical and antimicrobial treatment, complications, and outcomes were retrieved from patients' electronic medical records and analyzed. RESULTS There were 48 episodes of NTM cervicofacial lymphadenitis in 45 children (17 males and 28 females). Of these episodes, 43.7% manifested as a unilateral single node, mostly parotid (39.6%) and submandibular (29.2%). All patients underwent diagnostic fine-needle aspiration or surgery. Surgical excision more frequently yielded positive histological findings (P = .016). NTM was identified in 22/48 episodes (45.8%) via culture or molecular sequencing. Mycobacterium abscessus was most commonly found (47.8%). Thirty-eight children (79.2%) received antibiotics. Outcomes in 43 episodes revealed full resolution in 69.8%, while 25.6% had de novo disease and 4.6% experienced recurrence at the same site. Overlying skin changes and multiple or bilateral nodal diseases were significantly associated with de novo disease or recurrence (P = .034 and .084, respectively). Complications occurred in 11/70 (15.7%) procedures. Antibiotic-associated adverse effects occurred in 14/38 (36.8%) episodes. CONCLUSIONS NTM lymphadenitis remains a challenging condition. More aggressive management with surgical excision and antibiotics is recommended for those with overlying skin changes and extensive nodal disease.

Abstract
Background Reports of periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome from developing countries are sparse. Recognizing PFAPA is often challenging in these regions due to a higher incidence of infectious illnesses and significant resource constraints. Herein, we present our experience from North India regarding the diagnosis and management of PFAPA syndrome. Methods We reviewed cases of non-monogenic periodic fever syndrome diagnosed at our center from January 2011 to December 2021. A total of 17 children who fulfilled the Marshall criteria for PFAPA syndrome were included. Data regarding basic clinical features, treatment/outcome, and performance of the recently proposed Eurofever/PRINTO and Takeuchi criteria were analyzed. Results Besides recurrent fever, the triad of oral aphthae, pharyngitis, and adenitis was noted in only 18% of patients. Episodes of exudative pharyngitis/tonsillitis were documented in 24%. These figures were lower than the values reported from developed countries. The Takeuchi and Eurofever/PRINTO criteria were fulfilled in 76% and 71% cases, respectively. In addition to antipyretics and supportive care, intermittent steroid therapy was the main treatment modality used. Additional treatment with colchicine (n = 3) and thalidomide (n = 1) was used successfully in a few patients. Before the diagnosis of PFAPA, all patients had received multiple courses of antimicrobials (without microbiological confirmation). These included multiple courses of antibacterials for fever, pharyngotonsillitis, and/or cervical adenitis in all patients and antivirals for fever and aphthous stomatitis in a patient. Empiric antitubercular therapy had also been administered in two patients. Conclusions A significant proportion of patients with PFAPA seem to remain undiagnosed in the Indian subcontinent. Increased awareness and improvement in basic healthcare facilities are crucial in enhancing the recognition of PFAPA, which would eliminate the unprecedented scale of undesirable antimicrobial use in such children.

Abstract
Objective: To investigate the economic burden of bacillus Calmette-Guérin (BCG) lymphadenitis in Shandong Province. Methods: From May 2011 to December 2019, 304 patients applying for the province-level compensation of BCG lymphadenitis was selected from Shandong Province in this study. The basic situation, vaccination, outpatient (inpatient) records, cost and relevant information of those patients were collected to calculate the direct economic burden (including direct medical costs and direct non-medical costs), indirect economic burden and total economic burden. Comparison of the difference of economic burden of cases with different characteristics was taken. Results: The M(Q1,Q3) of age of BCG lymphadenitis patients was 3 (2, 4) months, among which 239 cases (78.6%) were male, 71 cases (23.4%) had lymphadenopathy, and 227 cases (74.7%) underwent surgery.The number of outpatient only, inpatient only and outpatient then inpatient was 25.7% (78 cases), 7.2% (22 cases) and 67.1% (204 cases), respectively. The M(Q1,Q3) of direct, indirect and total economic burden of single case after discount was 9 910 (5 713, 16 074), 2 081 (1 547, 3 122) and 12 262 (7 694, 18 571) yuan, respectively.The direct medical expenses accounted for 89.4% of the direct economic burden, the direct economic burden accounted for 84.9% of the total economic burden, the total economic burden of 80.0% cases accounted for only about 20.0% of the compensation amount, and the total economic burden of only 2.3% cases accounted for more than 60.0% of the compensation amount.The direct, indirect and total economic burden of patients with inpatient only and outpatient then inpatient was higher than that of patients with outpatient only; the direct, indirect and total economic burden of patients with operation was higher than that of patients with non-operation; the direct and total economic burden of patients with unulcerated lymph node was higher than that of patients with ulcerated lymph node(all P values<0.05). Conclusion: The economic burden of BCG lymphadenitis cases in Shandong Province is influenced by the mode of diagnosis and treatment, with direct medical expenses as the predominant component.

Abstract
BACKGROUND Tuberculosis and human immunodeficiency virus (HIV) are among the major health problems in Ethiopia. This study assessed the proportion of tuberculosis lymphadenitis (TBLN), HIV infection and their co-infection among TBLN presumptive individuals at the selected hospitals in Northwest Ethiopia. METHODS Institution based cross sectional study was carried out. Data on demographic and clinical variables were collected with standardized questionnaire. Microbiological culture was done on specimen obtained by fine needle aspirates. The HIV status was determined by rapid anti-HIV antibody test. Data was entered and scrutinized using SPSS version 20 statistical packages. A stepwise logistic regression model was used. The result was considered as statistically significant at P<0. 05. RESULTS A total of 381 lymphadenitis patients were included in the study. The overall prevalence of TBLN and HIV were at 250(65.6%) and 9(2.4%), respectively and their co-infection was at 6(2.4%). Based on the cytological examination, 301(79.0%) of them were diagnosed as TBLN. The age group, (P=0.01) and residency, (P=0.01) were found significantly associated with TBLN. Similarly, unsafe sex was also statistically significant for HIV infection (P=0.007). CONCLUSION Tuberculosis lymphadenitis is the leading cause of TB and lymphadenitis in the region. However, TBLN-HIV coinfection was promisingly low. High rate of discrepancy was noticed between cytological and culture results. Hence, the TBLN diagnostic criteria shall pursue revision.

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
Caseous lymphadenitis (CLA) or pseudotuberculosis is a chronic zoonotic bacterial disease caused by Corynebacterium pseudotuberculosis, which affects livestock and humans. This study aimed to describe the pathology, bacteriology and confirm the identity of the pathogen by 16S rRNA gene sequencing in Camelus dromedarius. A total of 12 camels with suspected CLA in three regions of Abu Dhabi Emirate (Abu Dhabi, Al Ain and Al Dhafra), United Arab Emirate (UAE) were subjected to clinical and postmortem examinations from January 2015 to December 2020. Clinically, camels were emaciated and showed the presence of external caseous abscesses suggestive of CLA. Postmortem examination showed multiple abscesses of variable sizes with caseous material encapsulated by fibrous tissue in the liver, lungs, muscle, and lymph nodes. Following clinical and postmortem examination, blood, pus and different tissue samples were collected for subsequent analysis. Histopathological examination of all organs stained with Hematoxylin and Eosin (H&E) indicated a central caseo-necrotic core that was admixed with bacterial colonies and infiltration of chronic inflammatory cells, surrounded by a pyogenic membrane, and an outer fibrous connective tissue capsule. Bacterial culture identified the isolates of Corynebacterium pseudotuberculosis biotype ovis strain, and these isolates were shown to be sensitive to all antibiotics tested (penicillin, ampicillin, Co-trimoxazole, enrofloxacin and tetracycline). Moreover, the identity of the isolates was confirmed by partial sequencing of the 16S rRNA gene which showed a 100% identity to Corynebacterium pseudotuberculosis. Phylogenetic analysis based on 16S rRNA gene sequence clearly differentiates Corynebacterium pseudotuberculosis from other species of Corynebacterium. Briefly, this study provided the basic information for infection of Corynebacterium pseudotuberculosis in Camels and will help in controlling of this pathogen in the region.

Abstract
BACKGROUND Neither the incidence of indications for childhood tonsillectomy nor the proportion of tonsillectomies that are evidence-based is known. AIM To determine the incidence of indications for tonsillectomy in UK children, and the proportion of tonsillectomies meeting evidence-based criteria. DESIGN AND SETTING A retrospective cohort study of electronic medical records of children aged 0-15 years registered with 739 UK general practices contributing to a research database. METHOD Children with recorded indications for tonsillectomy were identified from electronic medical records. Evidence-based indications included documented sore throats of sufficient frequency and severity (Paradise criteria); periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis syndrome (PFAPA); or tonsillar tumour. Other indications were considered non-evidence-based. The numbers of children subsequently undergoing tonsillectomy was then identified. The numbers with evidence-based and non-evidence-based indications for surgery among children who had undergone tonsillectomy were determined. RESULTS The authors included 1 630 807 children followed up for 7 200 159 person-years between 2005 and 2016. Incidence of evidence-based indications for tonsillectomy was 4.2 per 1000 person years; 13.6% (2144/15 760) underwent tonsillectomy. Incidence of childhood tonsillectomy was 2.5 per 1000 person years; 11.7% (2144/18 281) had evidence-based indications, almost all with Paradise criteria. The proportion of evidence-based tonsillectomies was unchanged over 12 years. Most childhood tonsillectomies followed non-evidence-based indications: five to six sore throats (12.4%) in 1 year, two to four sore throats (44.6%) in 1 year, sleep disordered breathing (12.3%), or obstructive sleep apnoea (3.9%). CONCLUSION In the UK, few children with evidence-based indications undergo tonsillectomy and seven in eight of those who do (32 500 of 37 000 annually) are unlikely to benefit.

Abstract
OBJECTIVE Introduction: The acute and chronic inflammatory processes prevail in the structure of the dental surgical diseases in children. Notably, various forms of lymphadenitis, adenophlegmon and odontogenous osteomyelitis dominate in the specialized surgical units; however, it is not possible to resolve a number of organizational problems without clear understanding of the statistical situation. The aim: The paper is aimed at the analysis of the incidence rate of major nosological forms of the acute suppurative inflammations of the maxillofacial area in children for the prospective planning of arrangements to provide them with high-quality specialized care. PATIENTS AND METHODS Materials and methods: The paper involves findings of comprehensive examination and treatment of 537children with acute purulent lymphadenitis, adenophlegmon and odontogenous osteomyelitis that was carried out within 6 years. RESULTS Results: The resulting clinical data have shown that three abovementioned nosological forms of the disease accounted for 42% of the overall number of the inpatient dental patients and 11% of the total number of children with acute surgical pathology. Out of 537 patients, 240 patients (44.8%) with acute purulent lymphadenitis, 150 (27,9%) patients with adenophlegmon and 147 (27.3%) patients with acute odontogenous osteomyelitis have been observed (318 (59,2%) boys and 219 (40,8%) girls aged from 2 months to 15 years). The study of the past history of the disease has established that in the majority of patients burdened premorbid history and occurrence of concomitant chronic general somatic diseases was presented prior to the onset of acute inflammation. CONCLUSION Conclusions: The factors, mentioned above, greatly contributed to increase in protective-adaptive properties of child body and create the prerequisites for the formation of pathological symptomocomplex in children, which can be implemented even in the minimal effect of antigen load on the tissues of maxillofacial area. Such situation requires a balanced multidisciplinary approach to the planning of preventive measures in this category of patients at all stages of the observation.

Abstract
Thirteen Corynebacterium pseudotuberculosis biotype ovis strains isolated from clinical cases of caseous lymphadenitis in Hungary were characterised using multilocus sequencing and their phylogenetic comparison was carried out on the basis of four housekeeping genes (groEL1, infB, dnaK, and leuA). The in silico analysis of the 16 frequently studied housekeeping genes showed that C. pseudotuberculosis strains could be readily distinguished from C. diphtheriae and C. ulcerans strains; however, sequences of the same genes in the two biotypes of the C. pseudotuberculosis were highly similar; the heterogeneity values were low. Genes dnaK, infB, groEL1, and leuA showed marked genetic variation within C. pseudotuberculosis, and strains of the two biotypes of C. pseudotuberculosis could be differentiated. Analysis of the individual genes showed a fairly conservative nature of C. pseudotuberculosis biotype ovis strains. The greatest genetic differentiation was seen in the dnaK and infB genes and concatenations of these two genes were very useful in the genetic separation of the studied strains.

Abstract
Importance Human immunodeficiency virus (HIV) infection is associated with a high risk of cardiovascular disease and increased arterial inflammation. In HIV, inflammation is also increased within lymph nodes (LNs), tissues known to harbor the virus even among treated and suppressed individuals. Objective To test the hypothesis that arterial inflammation is linked to HIV disease activity and to inflammation within HIV-infected tissues (LNs). Design, Setting, and Participants For this case-control study, participants were recruited from the SCOPE (Observational Study of the Consequences of the Protease Inhibitor Era) cohort, a clinic-based cohort of individuals receiving care at San Francisco General Hospital and the San Francisco Veteran's Affairs Medical Center. Arterial and LN inflammation were measured using 18F-fluorodeoxyglucose positron emission tomography. Detailed immunophenotyping was performed, along with measurement of viral activity/persistence and of circulating inflammatory biomarkers. Main Outcomes and Measures Arterial and LN inflammation. Results A total of 74 men were studied (45 HIV-infected men with a median age of 53 years [interquartile range, 49-59 years] and 29 uninfected male controls with a median age of 52 years [interquartile range, 46-56 years]). Lymph node inflammation was higher in HIV-infected individuals and correlated with markers of viral disease activity (viral load, CD8+ T cells, and CD4/CD8 ratio) and CD4+ T-cell activation. Uninfected controls had the lowest LN activity (mean [SD] maximum axillary LN standardized uptake value, 1.53 [0.56]), the elite controller and ART-suppressed groups had intermediate levels of LN (mean [SD] maximum axillary LN standardized uptake value, 2.12 [0.87] and 2.32 [1.79], respectively), and the noncontrollers had the highest activity (mean [SD] maximum axillary LN standardized uptake value, 8.82 [3.08]). Arterial inflammation was modestly increased in HIV-infected individuals and was positively correlated with circulating inflammatory biomarkers (high-sensitivity C-reactive protein and IL-6) and activated monocytes (CD14dimCD16+; nonclassical) but not with markers of HIV. While LN and arterial inflammation were increased in HIV, inflammatory activity in these tissues was not related (r = 0.09, P = .56). Conclusions and Relevance While LNs and, to a lesser degree, the arterial wall are inflamed in HIV, inflammation in these tissues is not closely linked. Namely, measures of HIV disease activity are strongly associated with LN inflammation but not with arterial inflammation. These data suggest that LN and arterial inflammation do not share underlying pathways of immune activation and also that therapeutic interventions that reduce viral disease activity may not predictably reduce arterial inflammation in HIV or its downstream consequence (ie, cardiovascular disease).

Abstract
Background Nontuberculous mycobacteria (NTM) are environmental organisms associated with a range of infections. Reports of NTM epidemiology are mainly focused on pulmonary infections and isolations, and extrapulmonary infections are less frequently described. Methods We conducted a retrospective study of NTM infections at the Bordeaux University Hospital, France, between January 2002 and December 2013. We used the microbiologic component of the American Thoracic Society/Infectious Diseases Society of America's pulmonary NTM disease criteria to define cases of pulmonary NTM, and patients with isolates from a normally sterile site were classified as having extrapulmonary disease. Results In our setting, 170 patients were included. Pulmonary cases predominated (54.1%), followed by skin and soft tissue infections (22.9%), disseminated cases (10.6%), lymphadenitis (7.7%), bone and joint infections (2.9%) and the remaining 1.8% catheter-related infections. Overall, 16 NTM species were isolated. Mycobacterium avium (31.8%) and M. intracellulare (20%) were the most common species identified, followed by M. marinum (13.5%), M. kansasii (10.6%), M. xenopi (9.4%), rapidly growing mycobacteria (9.4%) and other slowly growing mycobacteria (5.3%). In general, NTM isolates were largely prevalent in people older than 50 (62.4%); patients aged 1–10 year-old exclusively yielded M. avium from lymph nodes, almost cases having being diagnosed after 2007. Among the 121 patients with complete follow-up, 78 (64.5%), 24 (19.8%), and 19 (15.7%) were cured, experienced relapse, or died, respectively. Conclusion In our study, extrapulmonary NTM infections represented almost half of cases, consisting mainly in skin and soft tissue infections. The increase lymphadenitis cases in children after 2007 could be linked to the cessation of mandatory BCG vaccination in France. We observed similar cure rates (64%) between pulmonary and extrapulmonary infections.

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.

Abstract
BACKGROUND In 2010, an Iberian ibex (Capra pyrenaica hispanica) stock reservoir was established for conservation purposes in north-eastern Spain. Eighteen ibexes were captured in the wild and housed in a 17 hectare enclosure. Once in captivity, a caseous lymphadenitis (CLA) outbreak occurred and ibex handlings were carried out at six-month intervals between 2010 and 2013 to perform health examinations and sampling. Treatment with a bacterin-based autovaccine and penicillin G benzatine was added during the third and subsequent handlings, when infection by Corynebacterium pseudotuberculosis was confirmed. Changes in lesion score, serum anti-C. pseudotuberculosis antibodies and haematological parameters were analyzed to assess captivity effects, disease emergence and treatment efficacy. Serum acute phase proteins (APP) Haptoglobin (Hp), Amyloid A (SAA) and Acid Soluble Glycoprotein (ASG) concentrations were also determined to evaluate their usefulness as indicators of clinical status. Once in captivity, 12 out of 14 ibexes (85.7%) seroconverted, preceding the emergence of clinical signs; moreover, TP, WBC, eosinophil and platelet cell counts increased while monocyte and basophil cell counts decreased. After treatment, casualties and fistulas disappeared and both packed cell volume (PCV) and haemoglobin concentration significantly increased. Hp, SAA and ASG values were under the limit of detection or showed no significant differences. CONCLUSIONS A role for captivity in contagion rate is suggested by the increase in antibody levels against C. pseudotuberculosis and the emergence of clinical signs. Although boosted by captivity, this is the first report of an outbreak of caseous lymphadenitis displaying high morbidity and mortality in wild ungulates. Treatment consisting of both vaccination and antibiotic therapy seemed to prevent mortality and alleviate disease severity, but was not reflected in the humoural response. Haematology and APP were not useful indicators in our study, perhaps due to the sampling frequency. Presumably endemic and irrelevant in the wild, this common disease of domestic small ruminants is complicating conservation efforts for the Iberian ibex in north-eastern Spain.

Abstract
The objective of this study was to evaluate the diagnostic performance of two ELISA tests applied to bulk tank milk (BTM) as the first part of a two-step test scheme for the surveillance of caprine arthritis encephalitis (CAE) and caseous lymphadenitis (CLA) infections in goats. The herd-level BTM tests were assessed by comparing them to the test results of individual serological samples. The potential for refining the cut-off levels for BTM tests used as surveillance tools in a population recently cleared of infection was also investigated. Data was gathered on serum (nCAE =9702 and nCLA=13426) and corresponding BTM (nCAE=78 and nCLA=123) samples from dairy goat herds enrolled in the Norwegian disease control and eradication programme 'Healthier Goats'. The results showed that the sensitivity and specificity of the CAE ELISA BTM test with respect to detecting ≥2 per cent within-herd prevalence were 72.7 per cent and 86.6 per cent, respectively. For the CLA ELISA BTM the sensitivity and specificity were 41.4 per cent and 81.7 per cent, respectively, for the same goal of detection. The results suggest that BTM testing can be applied as a cost-effective first step for early detection of CAE and CLA infection.

Abstract
OBJECTIVES The aims of this study were to describe the clinical features of periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) and identify distinct phenotypes in a large cohort of patients from different countries. METHODS We established a web-based multicentre cohort through an international collaboration within the periodic fevers working party of the Pediatric Rheumatology European Society (PReS). The inclusion criterion was a diagnosis of PFAPA given by an experienced paediatric rheumatologist participating in an international working group on periodic fever syndromes. RESULTS Of the 301 patients included from the 15 centres, 271 had pharyngitis, 236 cervical adenitis, 171 oral aphthosis and 132 with all three clinical features. A total of 228 patients presented with additional symptoms (131 gastrointestinal symptoms, 86 arthralgias and/or myalgias, 36 skin rashes, 8 neurological symptoms). Thirty-one patients had disease onset after 5 years and they reported more additional symptoms. A positive family history for recurrent fever or recurrent tonsillitis was found in 81 patients (26.9%). Genetic testing for monogenic periodic fever syndromes was performed on 111 patients, who reported fewer occurrences of oral aphthosis or additional symptoms. Twenty-four patients reported symptoms (oral aphthosis and malaise) outside the flares. The CRP was >50 mg/l in the majority (131/190) of the patients tested during the fever. CONCLUSION We describe the largest cohort of PFAPA patients presented so far. We confirm that PFAPA may present with varied clinical manifestations and we show the limitations of the commonly used diagnostic criteria. Based on detailed analysis of this cohort, a consensus definition of PFAPA with better-defined criteria should be proposed.

Abstract
In order to determine the frequency of seropositive cases of Bartonella henselae in children with regional adenitis treated in a national hospital in Peru, a cross-sectional study was conducted in 106 children with regional adenitis greater than 1 cm in diameter. The sample was selected from patients aged 5-11 years seen at the National Institute of Child Health for acute onset of regional adentitis, with more than five days of symptoms. B. henselae seropositivity was defined by indirect immunofluorescence test. We found that 86 children (81.1%) were positive for B.henselae. The median age of the patients was 7 years. In the bivariate analysis, the following associated factors were found: aged 5 years, history of fever, lymphadenopathy greater than 4 cm and reported contact with cat. In conclusion, children with regional adenitis treated in this national referral hospital showed a high frequency of positive serology for B. henselae.

Abstract
OBJECTIVE The aim of this study was to investigate the distribution of caseous lymphadenitis (CLA) among small ruminants in Egypt, identify risk factors associated with its occurrence and to analyze the efficacy of the vaccine for control of CLA. MATERIAL AND METHODS A total of 1206 sheep and 351 goats were examined clinically for CLA. The prevalence and the risk factors of CLA in small ruminant flocks were estimated and identified. Efficacy of the commercial vaccine Case-Bac (Colorado Serum Company, USA) was determined in a field study trial conducted on 15 CLA-free lambs. Follow-up of vaccination immune response was carried out using indirect ELISA. RESULTS Prevalence of superficial CLA was 6.7%. Clinically, CLA appeared as abscesses in superficial lymph nodes mostly of the head and neck. On the basis of a multivariate analysis which accounted for clustering at herd level, sheep were at risk of getting superficial CLA 3.5 times more than goats (p < 0.0001). Animals of fixed flocks were at risk of getting the superficial CLA 2 times more than animals in fixed-mobile flocks (p < 0.038). Serological follow-up indicated protective antibody titers for 6 months. In vaccinated animals clinical cases were not observed while they occurred among non-vaccinated sheep. DISCUSSION Prevalence of CLA varied among studied flocks even between those of the same breeding system due to complex and overlapping factors associated with each flock like introduction or culling rate of animals, care of shepherds or owners to deal with opened abscesses in addition to the average age of the animals within each flock. Breeding systems have observable effects on occurrence of CLA: infected sheep can transmit the infection to a large number of animals in a short period under the conditions of close contact and reduced air flow in covered sheds. CONCLUSION AND CLINICAL RELEVANCE Infected small ruminants in fixed flocks represent a risk factor for CLA for healthy ones. The vaccine used in the study provides an effective protection against new infections. So mass vaccination of small ruminants against CLA in Egypt has to be considered to minimize the disease prevalence.

Abstract
OBJECTIVES This paper aims to describe clinical and laboratory features and disease outcome in a single-centre cohort of patients with PFAPA syndrome (Periodic Fever, Aphtous stomatitis, Pharyngitis, and Adenitis) and to test performance of diagnostic and therapeutic algorithms. METHODS Patients fulfilling criteria were selected from the fever clinic population. Prospective follow-up together with recruitment of newly diagnosed patients followed pre-defined guidelines. Diagnostic and therapeutic algorithms and definitions of outcome and therapy response were formulated. Paired blood samples during febrile and afebrile periods were compared. RESULTS Out of 176 patients referred for suspected periodic fever 125 children fulfilled criteria. Their age at onset was 23 months, median episode duration 3.5 days at 4-week intervals. Fever was associated with pharyngitis (91%), cervical adenitis (78%) and aphtae (41%). Among therapeutic options, episodic prednisone proved to be the most common first-line treatment. Administered to 77 patients, it reduced symptoms in 94%. Tonsillectomy led to the full symptom resolution in all 18 patients. Forty-six patients reached disease remission. CONCLUSIONS Distribution of typical symptoms, response to therapies and disease outcome in a large patient cohort were documented. We offer diagnostic and therapeutic algorithms that have proven effective during this prospective trial. Our findings support the general belief of benign nature of this aetiologically unclear condition, despite proportion of patients having persistent disease for years. Maintenance of normal findings in afebrile intervals, striking response to a single dose of prednisone and normal growth and development together with spontaneous tendency towards prolongation of afebrile intervals are important confirmatory features of PFAPA syndrome.

Abstract
The objectives of this study were to determine the main causes of mortality, with a special focus on caseous lymphadenits as a cause of death or wasting in caprine herds from Quebec. Goats (n = 152) from 13 herds were submitted for necropsy; the cause of mortality, and the presence, location, and cause of abscesses (if present) were recorded. Proportional mortalities were distributed as: Clostridium perfringens type D enterotoxemia (17.1%), pneumonia (13.8%), paratuberculosis (10.5%), listeriosis (6.6%), pregnancy toxemia (5.3%), caprine arthritis-encephalitis (4.6%), and caseous lymphadenitis (3.9%). Caseous lymphadenitis was diagnosed in 24.3% of the submitted goats, but was not a major cause of wasting or mortality. Abscesses were localized internally in 54.1% of the cases. Paratuberculosis was diagnosed in 29 goats (16 as cause of death) and was considered a major cause of wasting and/or mortality.

Abstract
INTRODUCTION Nontuberculous mycobacteria are ubiquitous organisms readily isolated from natural waters, drinking water systems and soil. They form a continuous challenge to the human immune system which becomes apparent in patients with impaired immunity. However, most infections occur in seemingly healthy children. The clinical presentation consists of a unilateral, non-tender, persistent, cervical lymphadenopathy without systemic illness. Fistula formation may occur. MATERIAL AND METHODS Patients were included if one or more of the following were positive; 1) mycobacterial culture, 2) acid-fast microscopy, 3) polymerase chain reaction and/or 4) granulomatous inflammation. RESULTS On the basis of operative management, two distinct groups were established. Group 1 had an excision of all pathological tissue performed and Group 2 was treated with incision and drainage. There was a difference between the two groups in regard to the risk of developing a postoperative fistula. In Group 1, 50% developed a fistula compared with 91% in Group 2 (p = 0.06). CONCLUSION Surgical treatment is generally advocated as the treatment of choice. Antibiotic treatment is associated with adverse effects and avoidance of surgery does not justify the inferior results related to antibiotics. A watch-and-wait strategy or antibiotic therapy may be considered when surgical excision carries a high risk of facial nerve injury. Although the lymph nodes may persist for months, spontaneous regression may occur and the children remain systemically well. FUNDING not relevant. TRIAL REGISTRATION not relevant.

Abstract
Lymphadenitis caused by nontuberculous mycobacteriae has been increasingly seen in Finland since the cessation of universal BCG vaccination in 2006. An otherwise healthy child develops a slowly growing unilateral mass in the cervicofacial region. Without treatment, the lymphadenitis suppurates and forms a draining sinus, which dries after some weeks or months, leaving a scar. Surgical excision is curative treatment but cannot always be performed because of risk to the facial nerve or need of extensive surgery. In these cases, observation without antimicrobial treatment is usually recommended. The parents need professional information and support.

Abstract
OBJECTIVE The annual incidence of nontuberculous mycobacterial (NTM) cervicofacial lymphadenitis in otherwise healthy children is unexpectedly high (8 per million). It mostly arises as localized cervicofacial lymphadenitis. Previous research has suggested environmental risk factors for oral exposure to NTM and a temporal association with eruption of teeth. We studied 22 polymorphisms in relevant candidate genes, some related to periodontitis, in children with NTM lymphadenitis. We also tested for the most common mutation in IFNGR1. METHODS We analyzed DNA from 81 Dutch children with NTM from a nationwide surveillance study and 215 community controls for 22 polymorphisms in CD209, IL1B, IL8, IL10, IL12B, IL12RB1, IL18, PTX3, TLR4, TNF, VDR and SLC11A1 by MassArray platform (Sequenom) and CONTING. We screened for 818del4 in IFNGR1 by PCR and VspI restriction enzyme cleavage. RESULTS We found a positive association between NTM lymphadenitis and +3953TT in IL1B (OR 2.9; 95%-CI: 1.2-7.2). Furthermore, our results showed that -592C/A heterozygosity in IL10 is linked to protection from disease (OR 0.54; 95%-CI: 0.3-0.95), but that other polymorphisms were unrelated to localized NTM disease. However, these associations were not robust to Bonferroni's correction for multiple testing. None of the children carried the IFNGR1 818del4 mutation. CONCLUSIONS Dominance of environmental factors over genetic ones and insufficient sample size might explain the fragility of this study's results. Nevertheless, the association between NTM lymphadenitis and 3953C>T, a polymorphism previously linked to periodontitis, supports our hypothesis that oral exposure to mycobacteria during eruption of teeth plays a role in the etiology of cervical NTM lymphadenitis.

Abstract
A descriptive record-based review of adverse events following immunization (AEFI) was carried out in Oman using the national database for the period 1996-2005. A total of 790 adverse event reports were received with an annual rate during the review period of 33.7 per 100 000 population or 10.8 per 100 000 doses administered. There were no reported deaths. The most frequently reported AEFI were BCG adenitis (69.7 per 100 000 doses) and local reactions (3.6 per 100 000 doses respectively). The statistically significant higher rates among males, in children aged > 2 years and in some sparsely populated regions of Oman need further research. AEFI rates in Oman were similar or below the international averages

Abstract
Tularemia is a zoonotic disease caused by Francisella tularensis. The microorganism is transmitted to humans by contact with, or ingestion of, infected animal tissues, by insect bites, consumption of contaminated food or water, or from inhalation of aerolized bacteria. In this report we describe a case of tularemia presenting with multiple cervical lymphadenitis in Asturias (Spain). Final diagnosis was established based on a serological test. The patient was successfully managed with surgery and streptomycin for 2 weeks. The ulceroglandular form of tularemia should be considered in the differential diagnosis of cervical lymphadenitis, particularly in those not responding to penicillin treatment. To our knowledge, this is the first case described in Asturias, a north coast county of Spain.

Abstract
A survey of Caseous Lymphadenitis (CLA), a bacterial infection in sheep and goats was conducted on small ruminant farms in two districts in Perak, namely Kinta and Hilir Perak. The objective of this survey is to determine the status of CLA infection in small ruminants. A total of 8 farms were screened, involving a total of 579 animals. Agar Gel Precipitation Test (AGPT) and Enzyme Linked Immuno Absorbent Assay (ELISA) were conducted on serum samples obtained from the animals. Results show that 8.5% of the animals had a positive reaction for AGPT test. It was found that 36 samples (17%) were found positive using both AGPT and ELISA methods, 9 samples (4%) were found positive only using AGPT method, 14 samples (6%)were found positive only using ELISA and 157 samples (73%) were found negative using both methods. Since there is no available data on the prevalence of the disease in the country, further epidemiological studies as well as reliable diagnostic detection methods need to be assessed for aiding in control and eradication programmes for this disease.

Abstract
OBJECTIVES To determine whether there is an increase in the incidence of nontuberculous mycobacteria (NTM) adenitis at our tertiary care pediatric hospital and to determine whether there is an association between geographic location and prevalence of cases. Also, to investigate the role of nongeographic risk factors such as bacille Calmette-Guérin (BCG) vaccination in the incidence of NTM adenitis. METHOD We conducted a retrospective chart review of 153 pediatric patients with NTM adenitis diagnosed between 1994 and 2004 and a prospective telephone survey of geographic and nongeographic risk factors for 82 patients. RESULTS The annual incidence, calculated with the number of hospitalizations for that year as the denominator, was 25.1 in 100,000 during the 1994-1998 period and 107.4 in 100,000 for 1999-2004. A statistically significant increase in the incidence of NTM adenitis was observed after 1999, with an incidence ratio of 4.28 (95% confidence interval 2.84-6.65; p < .0000). We found a nonsignificant increase in incidence for cases in the suburbs compared with the city. The survey did not reveal any significant risk factors for NTM adenitis in our population. However, none of the affected children had had the BCG vaccination. CONCLUSION There has been a significant increase in the incidence of NTM adenitis at our tertiary care centre, particularly since 1999. No clear risk factors could be identified to account for this increase, even though geographic location and discontinuation of BCG vaccination could be implicated. More studies are needed to confirm those hypotheses.

Abstract
BACKGROUND Sebaceous adenitis (SA) is an uncommon, immune mediated skin disease in dogs. The aim was to retrospectively investigate SA in dogs in Sweden with respect to breed, sex and age distribution. A second aim was to retrospectively compare clinical signs in dogs with generalized SA and to estimate the survival after diagnosis in the English springer spaniel, standard poodle and the akita. METHODS In total 34 Swedish veterinarians contributed with 104 clinically and histologically verified SA cases. Breed, gender and age at diagnosis were registered for each case. The degree of clinical signs at time for diagnosis and at follow-up and information about treatments, concurrent diseases and euthanasia were recorded for the springer spaniels, standard poodles and akitas using a standardized questionnaire. RESULTS A total of 104 cases of SA were included; most cases were recorded for the springer spaniel (n = 25), standard poodle (n = 21) and the akita (n = 10). These three breeds, together with the lhasa apso and the chow-chow, were the most common when national registry data from the Swedish Board of Agriculture and Swedish Kennel Club were considered. The mean age at diagnosis was 4.8 years. The proportion of males was 61%. When the springer spaniels, standard poodles and the akitas with generalized signs were compared (n = 51), the spaniels showed significantly more severe clinical signs than the poodles at diagnosis regarding alopecia, seborrhoea, pyoderma and the overall severity of clinical signs. At follow-up, the degree of clinical signs for otitis externa and pyoderma differed significantly between the breeds. The estimated median survival time was 42 months. In dogs where data regarding survival was available at the end of the study (n = 44), SA was reported to be the reason for euthanasia in 14 dogs, whereof 7 within 24 months after diagnosis. CONCLUSION The result of this study implicates that the English springer spaniel is a breed predisposed to SA and that it has more severe clinical signs than the standard poodle. A large proportion of the dogs (spaniel, poodle and akita) investigated regarding survival were reported to have been euthanized to great extent due to the disease.

Abstract
UNLABELLED There are as yet no clear surgical guidelines for the management of BCG vaccine-induced regional axillary lymphadenopathy. OBJECTIVES The aim of this study was to evaluate the management of the condition and to suggest possible management strategies. METHODS A retrospective study was undertaken of 23 cases of suspected ipsilateral BCG adenitis following neonatal BCG inoculation (2001 - 2004). Diagnosis of a BCG infection was confirmed by culture and/or gastric washout. The age of the patient and mode of presentation, imaging findings, and results of tuberculin skin testing (Mantoux test) were documented. Because of a change in management policy the first group of patients treated by primary surgery were compared with those treated by fine-needle aspiration (FNA). The influence of HIV status on outcome was assessed. Surgical complications and outcome were analysed. RESULTS Twenty-three children under 13 years of age (mean age 8.8 months, male/female ratio 1.9:1) were evaluated. Eighteen patients tested positive for HIV and 5 were HIV-negative. A positive culture for BCG bacillus was identified in 19 cases (83%) - by FNA (N=13, 68%), on pus swab (N=3, 16%), at surgery (N=1, 5%), and by gastric washing (N=2, 11%). Three HIV-negative children had granulomas on histological examination without a positive culture. Forty-five per cent of the 11 patients treated early in the study period by primary surgery (drainage/biopsy) had complications, which included a difficult anaesthetic induction and technical surgical difficulties. The postoperative incidence of wound dehiscence/infection was extremely high in this group and 18.2% developed postoperative cutaneous sinuses. Following a change in management policy, the following 12 patients, with a comparable HIV incidence, treated by initial conservative management, had a much lower incidence of post-procedural complications. CONCLUSION This study confirms a high perioperative complication rate associated with the primary surgical treatment of BCG lymphadenitis in both HIV-positive and negative patients. Primary surgical treatment (incisional drainage or biopsy) is therefore not considered an ideal form of management in BCG lymphadenitis because of the high fistulisation and poor wound healing, especially in the HIV-positive patient. It should be avoided as the initial approach, with needle aspiration being preferred. Surgery should therefore be confined to the unusual event of real doubt about the underlying diagnosis and the treatment of suppurative complications.

Abstract
The aim of the study is to evaluate frequency, treatment and clinical type of adverse reaction (AEFI) after BCG vaccination. Between January 2003 and December 2006, 64 children with AEFI after BCG vaccination were registered in the Pediatric Vaccination Centre in Lódź. Different types of AEFI were distinguished on the basis of Lotte's classification (1977). On the basis of 265 registered cases of adverse events after compulsory vaccination, 41.1% (109/265) of them appeared as a result of BCG vaccination. The AEFI clinical analysis showed that in children aged up to 36 months the most frequent symptoms were auxiliary lymphadenitis 67.2% (43/64) or local subcutaneous abscess. In 43.8% (28/64) of cases after BCG vaccination surgical treatment was needed, including 17.2% (11/64) of children who had lymphadenectomy. The majority of AEFI cases after BCG vaccination were observed in children up to 36 months. The AEFI clinical analysis showed that in children aged up to 36 months the most frequent symptoms were regional lymphadenopathy and local subcutaneous abscess. The second most important strategy in AEFI treatment is the cooperation with surgeons. Higher rates of local reaction may result from incorrect methods of BCG vaccine administration.

Abstract
Caseous lymphadenitis (CLA) of sheep, caused by Corynebacterium pseudotuberculosis, has been a significant disease in the majority of sheep-rearing regions for over a century. Because of the chronic and often sub-clinical nature of the infection, it has proved difficult to control and prevalence is high in many parts of the world, which in turn leads to significant economic losses for farmers. This review describes the important characteristics of C. pseudotuberculosis and examines the pathogenesis and epidemiology of the infection in sheep. The review also discusses the immune response to infection and describes the methods that have been developed to control CLA, with particular emphasis on the use of vaccination and serological testing.

Abstract
AIM To record the incidence and clinical significance of nontuberculous mycobacteria (NTM) infection in New Zealand (NZ) in 2004. METHOD In 2004 each of NZ's mycobacterium reference laboratories collected data on NTM isolates. The clinical significance of isolates was decided by contacting the requesting clinician. American Thoracic Society criteria were used to assign clinical significance to respiratory isolates. RESULTS 368 patients had NTM isolated from various sites. 21% (78/368) were clinically significant [15% (47/316) of respiratory isolates, 100% (17/17) lymph node and 89% (8/9) of soft tissue isolates]. Of the significant isolates, Mycobacterium avium intracellulare complex (MAIC) was the most common, accounting for 83%, 88%, and 44% of respiratory, lymph node, and soft tissue infections respectively. Rapidly growing mycobacteria (RGM) were the second most common cause of significant infection. Of 47 patients with significant respiratory isolates 79% were female and 83% had underlying lung disease. The incidence of disease caused by NTM in NZ in 2004 was 1.92/100,000 population. The specific incidence of pulmonary, lymph node and soft tissue infections was 1.17, 0.39, and 0.24 per 100,000 population respectively. CONCLUSION The incidence of NTM respiratory disease in NZ during 2004 is approximately twice that recorded for Australia in 2000 (0.56/100,000). MAIC is the most common pathogen, followed by RGM. Both organisms most commonly cause respiratory infections in elderly female patients with underlying lung disease.

Abstract
We report the first case of canine lymphoadenomegalia caused by Cryptococcus neoformans in Chile. Physical examination of a Rottweiler dog patient showed a generalized lymphoadenomegalia that affected the submandibular, superficial cervical and popliteus lymphatic nodules. Cryptococcus neoformans was isolated and identified from biopsies of the right submandibular nodule. After antifungal susceptibility, oral ketoconazole treatment was established for a period of six months showing clinical improvement. Two years post-treatment the patient showed no signs of the infection.

Abstract
OBJECTIVE To study the clinical features, epidemiology and outcome of nontuberculous mycobacterial lymphadenitis (NTML). METHODS A retrospective study was performed on 54 patients under 14 years old diagnosed with atypical mycobacterial lymphadenitis between 1987 and 2004. Inclusion criteria were: (i) positive polymerase chain reaction (PCR) test or culture; (ii) positive sensitin skin test 6 mm above Mantoux; (iii) histopathologic features compatible with mycobacterial infection and/or positive direct smear for acid-fast bacilli, Mantoux reaction less than 15 mm, a normal chest radiograph, absence of exposure to an adult with tuberculosis, negative Mantoux test reactions in family members, and exclusion of other causes of granulomatous adenitis. RESULTS Fifty-four patients were included in the study. The number of NTML cases increased notably from 1996, coinciding with a decrease in cases of tuberculous adenitis. The mean age was 35 months (range: 14 months-6 years). Submandibular nodes were involved in 22 of 63 cases of adenitis (34.9%) and cervical nodes were involved in 21 (33.3%). In 8/42 patients (19%) the tuberculin skin test was larger than 10 mm. Cultures were positive in 52.9% of the cases (18/34) and PCR in 53.3% (8/15). The most frequently isolated mycobacteria was Mycobacterium avium (61%). Therapy failed in 8/21 patients receiving antibiotics (38%), in 10/13 patients with drainage alone (77%) and in none of the patients who underwent surgery (8/8). CONCLUSIONS Nontuberculous mycobacterial adenitis has become more frequent in our hospital since 1996. Cultures do not always allow isolation of mycobacteria and the Mantoux test frequently yields false positive results, thus hampering diagnosis. The most effective treatment was surgical excision. Nevertheless, when the surgical approach is difficult or there is postoperative recurrence, pharmacological treatment can be useful.

Abstract
BACKGROUND Nontuberculous mycobacteria (NTM) are a common cause of chronic cervicofacial lymphadenitis in young children. The differential diagnosis includes other infections, lymphoepithelial cysts and malignancies. OBJECTIVE To assess the sonographic findings of NTM cervicofacial lymphadenitis in children. MATERIALS AND METHODS We analysed the sonograms of cervicofacial lymph nodes of 145 children with microbiologically proven NTM lymphadenitis. RESULTS The size of the involved lymph nodes ranged from 1.9 cm to 4.4 cm. Most of the NTM patients (85%) presented in a stage of lymph node fluctuation with violaceous skin discoloration. On sonography, marked decreased echogenicity was seen in all cases. In 133 of the patients (92%) liquefaction with intranodal cystic necrosis, nodal matting and adjacent soft-tissue oedema were present. 66 children received antibiotic treatment, and the other children underwent surgical excision of the involved lymph nodes. In 69% of the patients successfully treated with antibiotics, multiple intranodal calcifications were present on sonography after 1 year. CONCLUSIONS Sonographic findings can provide additional diagnostic clues for NTM lymphadenitis in childhood. A marked decrease of echogenicity in the early stages, with intranodal liquefaction in the advanced stages, are universal features, albeit not entirely specific. Multiple intranodal calcifications are rather characteristic of end-stage mycobacterial infection.

Abstract
OBJECTIVES An estimated 15 million persons suffer from lymphoedema of the leg in filariasis-endemic areas of the world. A major factor in the progression of lymphoedema severity is the incidence of acute dermatolymphangioadenitis (ADLA), which is triggered by bacteria that gain entry through damaged skin, especially in the toe web spaces ('interdigital skin lesions'). Little is known about the epidemiology of these skin lesions or about patients' awareness of them. METHODS We interviewed and examined 119 patients (89% women) with lymphoedema of the leg in Recife, Brazil, an area endemic for bancroftian filariasis. RESULTS We detected 412 interdigital skin lesions in 115 (96.6%) patients (mean, 3.5 lesions per patient, range 0-8). The number of interdigital skin lesions was significantly associated with lymphoedema stage (P<0.001) and frequency of ADLA (P<0.0001). Only 20 (16.8%) patients detected their own interdigital skin lesions or considered them abnormal. Patients reported a mean of 3.6 ADLA episodes during the previous 12 months (range, 0-20); reported ADLA incidence was associated with lymphoedema stage (P<0.0001) and the number of interdigital skin lesions detected by the examining physician (P<0.0001). CONCLUSIONS These data suggest that interdigital skin lesions are a significant risk factor for ADLA and that persons with lymphoedema in filariasis-endemic areas are unaware of their presence or importance. Prevention of ADLA through prompt recognition and treatment of interdigital skin lesions will require that patients be taught to identify lesions, especially between the toes and to recognize them as abnormal.

Abstract
INTRODUCTION BCG vaccination is currently recommended for all newborns in Ireland except where specifically contraindicated. This paper describes a marked increase in the number of referrals of patients with localised complications after vaccination to two Dublin paediatric hospitals. This increase coincided with the introduction of a new strain of BCG vaccine METHODS A population surveillance study was undertaken to determine the frequency and spectrum of complications associated with the new strain of BCG vaccine introduced in Ireland. Patients were identified though review of the infectious disease service case records and microbiology laboratory culture reports for the two year period from August 2002 to July 2004. Prospectively gathered data were supplemented by retrospective chart review. All infants who had inoculation site abscesses, suppurative adenopathy, or non-suppurative adenopathy with nodes > or =2 cm were included. RESULTS Fifty eight patients presented a median of 13 weeks post-inoculation: 32 with suppurative adenitis, 17 with inoculation site abscess, three with both inoculation site abscess and suppurative adenitis, and six with non-suppurative adenopathy. The overall complication rate was estimated at 1/931 vaccinees with 1/1543 developing suppurative adenitis. Twenty six infants required surgery. DISCUSSION This series illustrates the role of hospitals in sentinel surveillance and highlights the importance of having a well functioning and responsive system of adverse event reporting. These events raise a serious question as to the suitability of this vaccine strain for use in a national immunisation programme in a country where the prevalence of tuberculous disease is 10.4/100,000.

Abstract
OBJECTIVE To determine the utility of prophylactic antibiotics in non-risk pediatric patients undergoing adenoidectomy. METHODS We performed a prospective, controlled, randomized, and double-blind study on patients under 14 years of age, scheduled for adenoidectomy who accomplished the following criteria: absence of immunosuppressive and/or cardiovascular risk factors, no antimicrobial therapy for at least 15 days prior to operation, and no fever 1 week before surgery. Venous blood samples for culture were obtained at 30s and 20 min after the curettage of adenoidal tissue. Likewise, immediate and delayed complications were registered in all cases. The usefulness of prophylaxis was analyzed according to three major standpoints: bacteremia, immediate complications, and delayed complications. RESULTS One-hundred one patients fulfilled the inclusion criteria and were included in the study. Fifty-one children received prophylaxis and the remainder did not. In the non-prophylactic group incidence of bacteremia at 30s was significantly higher than in the prophylactic group (32.7% versus 4.0%) (p<0.001). Neither bacteremia at 20 min, nor immediate or delayed complications showed statistical differences between both treatment groups. CONCLUSIONS Preoperative antimicrobial prophylaxis in pediatric adenoidectomy did not offer advantages preventing complications in non-risk patients. Only bacteremia that occurs 30s after the curettage of adenoid tissue is reduced with the employment of prophylactic antibiotics.

Abstract
BACKGROUND Lymphatic filariasis (LF) is a mosquito-borne nematode infection that causes permanent lymphatic dysfunction in virtually all infected individuals and clinical disease in a subset of these. One major sequel of infection is lymphoedema of the limbs. Lymphoedema of the leg affects an estimated 15 million persons in LF-endemic areas worldwide. Acute dermatolymphangioadenitis (ADLA) in people with filarial lymphoedema causes acute morbidity and increasingly severe lymphoedema. Episodes of ADLA are believed to be caused by bacteria, and it has been shown that entry lesions in the skin play a causative role. Clinical observations suggest that interdigital skin lesions of the feet, often assumed to be fungal, may be of particular importance. OBJECTIVES To investigate the epidemiology and aetiology of interdigital lesions (IDL) of the feet in filarial lymphoedema. METHODS The frequency and mycological aetiology of IDL in 73 patients with filarial lymphoedema were compared with 74 individuals without lymphoedema in a region of Guyana highly endemic for Wuchereria bancrofti. RESULTS More than 50% of patients with lymphoedema had one or more IDL (odds ratio 2.69; 95% confidence interval 1.31-5.66; P<0.005 compared with controls). The number of lesions was the strongest predictor of frequency of ADLA. Only 18% of the lesions had positive microscopy or culture for fungi (dermatophytes and Scytalidium). CONCLUSIONS These findings highlight the importance of interdigital entry lesions as risk factors for episodes of ADLA and have implications for the control of morbidity from filarial lymphoedema.

Abstract
Cat-scratch Disease as Cause of Lymphadenitis colli. Cat-scratch disease is a frequent cause of lymphadenitis colli. It mainly affects children and adolescents younger than 21 years. Since the clinical picture is not characteristic, a history of contact to cats or kittens is highly valuable for diagnosing the disease. Major aspects of the disease concerning epidemiology, diagnostic procedures, clinical presentation and therapy are discussed.

Abstract
The aim of the study was to describe the clinical and epidemiological features of children and adolescents with visceral leishmaniasis in Georgia. We performed a retrospective analysis of demographic, clinical and laboratory data from children and adolescents under age of 18 (n=200) with visceral leishmaniasis admitted to the referral center -- Tbilisi S. Virsaladze Institute of Parasitology between 2000 and 2005. Diagnosis was based on detection of amastigotes in the bone marrow punctate. Age ranged from 4 months to 15.9 years, the average age was 2.79+/-0.17 years. There were 84 girls and 116 boys. 190 cases came from Eastern Georgia (123 from the capital), 10 cases -- from Western Georgia. The period between manifestation of first clinical signs of the disease and admission to the referral center varied from 1 week to 1 year (6.8+/-0,6 weeks in average). Main clinical and laboratory presentations were splenomegaly and hepatomagaly, anemia, pancytopenia (84.5%). Among associated diseases, the most frequent were bronchitis and pneumonia (7.0%) and jaundice (3.5%). In all patients glucantime was used for treatment. One patient died. Visceral leishmaniasis can be considered as an important etiological agent of the fever of unknown origin in Georgia, particularly in Eastern Georgia and in children under six. Health care workers should be trained for the early recognition and appropriate management of visceral leishmaniasis and its complications.

Abstract
BACKGROUND AND PURPOSE Lymphadenitis is the most common manifestation of infection due to non-tuberculous mycobacteria (NTM) in otherwise healthy children. This disease is rare in adults and its geographic variations in etiology and clinical manifestations remain unclear. The aim of this study was to describe the etiology, clinical presentation, treatment, and outcome of NTM lymphadenitis. METHODS Medical records of patients with culture-proven NTM lymphadenitis treated at a university hospital in Taiwan from January 1997 through December 2004 were retrospectively reviewed. RESULTS In total, 12 patients with NTM lymphadenitis were identified, including 6 males and 7 adults (> or = 16 years). The majority (83%) of patients presented with an enlarged palpable mass and 9 (75%) had preceding constitutional symptoms. The most common site of lymphadenitis was the cervical area (83%) and 8 patients (75%) had multiple lymph node involvement. Rapidly growing mycobacteria (RGM) accounted for 75% of the etiology of NTM lymphadenitis, followed by Mycobacterium avium complex (MAC) [2 patients]. A high recurrence rate (42%) after primary treatment was noted among those patients who received clarithromycin-containing regimens for a median of 6 months. CONCLUSIONS This study found that both previously healthy children and adults were susceptible to NTM lymphadenitis. RGM was the most common etiology rather than MAC among NTM species causing lymphadenitis. Inadequate surgical excision of the diseased lymph nodes and insufficient coverage of antimycobacterial therapy both contributed to the high recurrence rate.
