RESUMO
OBJECTIVE: The burden of extra-pulmonary tuberculosis (EPTB) is not well quantified in TB endemic countries such as those in sub-Saharan Africa. This study aimed to quantify that burden via a systematic review of the prevalence of EPTB in African countries. METHODS: Studies were retrieved by searching five databases; 105 studies published between 1990 and 2023 were included. The studies described the prevalence of EPTB among the general population (4 studies), TB patients (68) and patients with other conditions, including HIV (15), meningitis (3), renal failure (3) and other comorbidities, some of which are cancer (12). Due to the low number of studies reporting EPTB in patients with conditions other than TB, the meta-analysis was performed on studies reporting on EPTB among TB patients (68 studies). Meta-analysis was performed on the 68 studies (271,073 participants) using a random-effects model to estimate the pooled prevalence of EPTB. Meta-regression was used to explore possible explanations for heterogeneity according to regions and time periods. RESULTS: The pooled prevalence of EPTB among TB patients was 26% (95% CI 23-29%). There was substantial heterogeneity of prevalence for the five African regions. The Eastern region had the highest prevalence of 32% (95% CI 28-37%) and the lowest in Western Africa, 16% (95% CI 10-24%). There was no significant difference in the prevalence of EPTB between the 3 eleven-year time periods. CONCLUSIONS: Our systematic review and meta-analysis give insight into the burden of EPTB in Africa. This review could inform clinical and programmatic practices-a higher suspicion index for clinicians and more effort for better services. This could contribute to efforts aiming to end TB, which have historically been focused on PTB.Coordinated efforts that target both EPTB and PTB are needed.

AIM: As herpes simplex virus (HSV) in infancy is not a mandatory notifiable condition in Australia, completeness of ascertainment by the Australian Paediatric Surveillance Unit (APSU) has been difficult to evaluate to date. We evaluated case capture in Queensland (QLD) and Western Australia (WA) using statewide laboratory and clinical data and complementary surveillance data collected via the APSU. METHODS: HSV polymerase chain reaction positive results in infants (0-3 months) from 2007 to 2017 were obtained from statewide public pathology providers in QLD and WA. Clinical data were extracted from patient records and compared to APSU reported cases. RESULTS: A total of 94 cases of HSV disease in infancy (70 QLD; 24 WA) were identified from laboratory data sets, compared to 36 cases (26 QLD; 10 WA) reported to the APSU. In total there was 102 unique cases identified; 28 cases were common to both data sets (seven skin eye mouth (SEM) disease, 13 central nervous system (CNS) disease and eight disseminated disease). Active surveillance captured 35% (36/102) of cases overall including 74% (14/19) of CNS, 71% (10/14) of disseminated and 17% (12/69) of SEM disease cases, respectively. Surveillance reported cases had a higher case-fatality rate compared to those not reported (14% vs. 3%, P = 0.038). Neurological sequelae at discharge were comparable between the groups. CONCLUSION: Active surveillance captures one third of hospitalised HSV cases in QLD and WA, including the majority with severe disease. However, morbidity and mortality remain high. Future studies on HSV will rely on observational studies. Enhanced case ascertainment through combined laboratory and surveillance data is essential for better understanding and improving outcomes.
RESUMO
BACKGROUND: Australia, like many high-income countries, is experiencing a resurgence of infectious syphilis in pregnancy and congenital syphilis. Evaluations of public health notifications and clinical records suggest that healthcare systems may not be providing optimal care to women and their neonates. This study aims to explore the barriers to optimal management of syphilis in pregnancy and congenital syphilis to identify key areas for improvement. METHODS: Between 2021 and 2022, 34 healthcare workers (HCW) practicing in south-east Queensland (SEQ) Australia were recruited to complete semi-structured interviews regarding their perceptions towards management of syphilis in pregnancy and congenital syphilis. Interviews were analysed thematically. RESULTS: Thematic analysis identified four themes related to the management of syphilis in pregnancy. These included poor communication between disciplines, services, and teams from delivery through to management and post-delivery, lack of formal internal and external referral pathways, unclear and often complex maternal and congenital syphilis management procedures, and limited HCW knowledge of infectious syphilis in pregnancy and congenital syphilis. CONCLUSION: As congenital syphilis numbers continue to rise in SEQ, it is imperative that healthcare systems and HCWs identify and address gaps in the provision of health care.

BACKGROUND: Increasing rates of syphilis in pregnancy (SiP) in Australia and other high-income countries, has led to the resurgence of congenital syphilis. Suboptimal syphilis screening during pregnancy has been identified as a key contributing factor. METHODS: This study aimed to explore, from the perspective of multidisciplinary healthcare providers (HCPs), the barriers to optimal screening during the antenatal care (ANC) pathway. Semi-structured interviews conducted with 34 HCPs across multiple disciplines practising in south-east Queensland (SEQ) were analysed through a process of reflexive thematic analysis. RESULTS: Barriers were found to occur at the system level of ANC, through difficulties in patient engagement in care, limitations in the current model of health care delivery and limitations in the communication pathways across health care disciplines; and at the individual HCP level, through HCP knowledge and awareness of epidemiological changes in syphilis in SEQ, and adequately assessing patient risk. CONCLUSION: It is imperative that the healthcare systems and HCPs involved in ANC address these barriers to improve screening in order to optimise management of women and prevent congenital syphilis cases in SEQ.

BACKGROUND: Staphylococcus aureus is a common cause of bacteremia, yet the epidemiology and predictors of poor outcome remain inadequately defined in childhood. METHODS: ISAIAH (Invasive Staphylococcus aureus Infections and Hospitalizations in children) is a prospective, cross-sectional study of S. aureus bacteremia (SAB) in children hospitalized in Australia and New Zealand over 24 months (2017-2018). RESULTS: Overall, 552 SABs were identified (incidence 4.4/100 000/year). Indigenous children, those from lower socioeconomic areas and neonates were overrepresented. Although 90-day mortality was infrequent, one-third experienced the composite of: length of stay >30 days (26%), intensive care unit admission (20%), relapse (4%), or death (3%). Predictors of mortality included prematurity (adjusted odds ratio [aOR],16.8; 95% confidence interval [CI], 1.6-296.9), multifocal infection (aOR, 22.6; CI, 1.4-498.5), necrotizing pneumonia (aOR, 38.9; CI, 1.7-1754.6), multiorgan dysfunction (aOR, 26.5; CI, 4.1-268.8), and empiric vancomycin (aOR, 15.7; CI, 1.6-434.4); while infectious diseases (ID) consultation (aOR, 0.07; CI .004-.9) was protective. Neither MRSA nor vancomycin trough targets impacted survival; however, empiric vancomycin was associated with nephrotoxicity (OR, 3.1; 95% CI 1.3-8.1). CONCLUSIONS: High SAB incidence was demonstrated and for the first time in a pediatric setting, necrotizing pneumonia and multifocal infection were predictors of mortality, while ID consultation was protective. The need to reevaluate pediatric vancomycin trough targets and limit unnecessary empiric vancomycin exposure to reduce poor outcomes and nephrotoxicity is highlighted. One in 3 children experienced considerable SAB morbidity; therefore, pediatric inclusion in future SAB comparator trials is paramount to improve outcomes.

PURPOSE OF REVIEW: In light of alarming increases in the incidence of congenital syphilis in many middle and higher income countries across the globe, this review summarizes recent changes in the epidemiology of syphilis, highlights recommended changes to testing in pregnancy and provides an update for the management of syphilis infection in pregnancy (SIP) and of the infant born to a mother with SIP. RECENT FINDINGS: The re-emergence of congenital syphilis is a result of increasing infectious syphilis in women of childbearing age, which is in turn a result of increasing syphilis in the general population particularly in Indigenous and marginalized populations. Potential reasons for the increase include changing sexual practices and increased travel and migration, as well as factors that limit healthcare access, particularly access to antenatal care and limited awareness and education amongst mothers and maternity services. A single antenatal test for syphilis is insufficient; more frequent testing in pregnancy is necessary even for women deemed to be low risk. The management of SIP and of the newborn is complex and guidelines should be readily available with clear recommendations. SUMMARY: Congenital syphilis is preventable. The current crisis calls for a global and national multipronged, co-ordinated approach involving public health and hospital systems which includes education of individuals and healthcare workers, availability of updated guidelines for prevention and treatment, prioritization of antenatal testing, assurance of accessible and prompt treatment and appropriate assessment and follow-up of infants.

AIM: Herpes simplex CNS infection is a rare but important cause of neurological disability. Long term outcomes after HSV CNS infection in Australia have not yet been fully described. We sought to provide a comprehensive review of HSV CNS infection in children using a retrospective 13-year evaluation of statewide laboratory and clinical records and a parent survey conducted at least one year after the initial infection. METHODS: All positive PCR HSV 1 and 2 results from cerebrospinal fluid (CSF) or brain tissue were obtained from Queensland pathology providers for children aged 0-16 years between 1 January 2005 and 31 December 2017. Clinical data were obtained from patient records and longer-term outcomes via parent survey at least 1 year after initial infection. RESULTS: Forty-three children were identified over the 13-year period, 17 (39.5%) neonates and 26 (60.4%) non-neonates. The annual incidence for HSV CNS infection in Queensland children aged ≤16 years was 0.3/100 000 (95% confidence intervals (CIs): 0.2-0.4) with neonates at highest risk (incidence 2.5/100 000 live births, 95% CI: 1.5-3.9). HSV 1 was the predominant serotype in both neonates and non-neonates (9/17, 52.9% neonates and 19/26, 73.1% non-neonates). Seven (16.3%) children died, five (5/17, 29.4% neonates), directly attributable to HSV CNS infection (all neonates). Twenty-five (58.1%) had neurological morbidity at discharge (9/17 neonates (52.9%) vs. 16/26 (61.5%) non-neonates) and 20/27 (74.1%) reported long-term neurological morbidity at follow-up (5/9 neonates (55.6%) vs. 15/18 non-neonates (83.3%)). Seven children (two neonates and four non-neonates) with long-term neurological sequelae had no neurological morbidity identified at discharge. CONCLUSION: Significant long-term neurologic sequelae were seen in children with HSV CNS infection even in children with no neurological disability identified at discharge from hospital. Careful neurodevelopmental follow-up of all children is recommended.

BACKGROUND: Syphilis in pregnancy and congenital syphilis (CS) are increasing in Australia. Prevention of adverse outcomes requires adherence to management guidelines. AIMS: The aim is to evaluate the management of syphilis in pregnant women and their newborns. MATERIALS AND METHODS: A retrospective study of public health notifications, clinical records and testing results of women with positive syphilis serology in pregnancy requiring treatment from 2016 to 2018 inclusive across South-East Queensland was conducted. Management was described and compared with contemporary guidelines from the Australasian Society of Infectious Diseases, the Communicable Diseases Network Australia and the United States Centers for Disease Control and Prevention. RESULTS: Of 30 women identified, 22 (73%) had management consistent with the guidelines (stage-appropriate penicillin regimen, appropriate dosing interval and treatment completed greater than 30 days before delivery). Only 14 (47%) women had documentation of partner testing and/or treatment. Of 26 mother-infant pairs with complete data, 16 (62%) had investigations at delivery consistent with recommendations (parallel maternal-infant rapid plasma reagin, infant syphilis immunoglobulin M, placental histopathology +/- syphilis polymerase chain reaction and infant clinical examination). One infant met the criteria for confirmed CS. Five infants received penicillin therapy. Only seven (27%) infants had serological monitoring after discharge. CONCLUSIONS: Management can be optimised with timely maternal testing and treatment, comprehensive partner screening and treatment, strict adherence to seven-day penicillin dosing for late latent syphilis and thorough maternal and infant testing after treatment and delivery. If maternal treatment was inadequate in pregnancy, consideration needs to be given to close evaluation and empiric treatment of the infant.

AIM: The rat lungworm, Angiostrongylus cantonensis, is well established in eastern Australia, where it is the almost exclusive cause of human eosinophilic meningoencephalitis (EME). While neuroangiostrongyliasis can result in severe morbidity or death, its diagnosis requires a high index of clinical suspicion among medical practitioners. Prevention requires a high level of public awareness. METHODS: We report two cases of EME in children from Queensland and summarise all reported Australian cases from the literature. We discuss the pathogenesis of neuroangiostrongyliasis, with particular reference to the timing of prophylaxis and treatment. RESULTS: A 5-year-old girl developed severe headache, eosinophilic meningitis and abnormal neuroimaging following a holiday to Bali. A 10-year-old boy with Rubinstein-Taybi syndrome, marked developmental delay and pica developed EME following ingestion of a snail, resulting in long-term morbidity. From 1971 to 2018, 28 Australian cases have been reported, with acquisition restricted to Southeast Queensland and New South Wales. Ages ranged from 10 months to 45 years; most were male and most likely acquired infection from consuming unwashed lettuce or vegetables. The mortality rate was 18%; most fatalities occurred in children <1 year old. Long-term neurological deficit was reported in 14% of cases and a full recovery in 57% of cases. CONCLUSIONS: Heightened medical and public awareness of the parasite is required to prevent infection and subsequent disease. A better understanding of the efficacy of prophylactic anthelmintic following ingestion or handling of molluscs and further studies of epidemiology of this parasite will inform and facilitate public health recommendations.

AIM: Q fever is a zoonotic disease caused by the bacterium Coxiella burnetii and is associated with significant morbidity and mortality in both adults and children. Australia is the only country that has produced and registered a Q fever vaccine for human use, but this vaccine is licenced only for people aged over 15 years as data and experience in children are limited. This review describes the experience of Q fever vaccination of known paediatric cases in Australia to date. METHODS: Patients aged younger than 15 years who received the Q fever vaccination had data abstracted from medical records after consent was obtained from the relevant guardians. Data on risk factors for Q fever, skin testing procedure, dose of vaccination, adverse effects and follow-up assessment were obtained. RESULTS: Twelve children were identified as having received the Q fever vaccination. Vaccination was feasible, with empirical weight-based dose adjustment performed for younger children. There were no significant adverse effects. CONCLUSIONS: Q fever vaccine may be safe in children and should be considered in children who are at significant risk of Q fever infection. Safe vaccine protocols with proven efficacy will allow children of all ages to be protected. Prospective studies of vaccination in children are indicated. Expanding available Q fever registries to include children would allow outcomes to be systematically followed.

AIM: Targeted screening by a salivary cytomegalovirus (CMV) polymerase chain reaction (PCR) of infants who 'refer' on their newborn hearing screen has been suggested as an easy, reliable and cost-effective approach to identify and treat babies with congenital CMV (cCMV) to improve hearing outcomes. This study aimed to investigate the feasibility and cost-effectiveness of introducing targeted salivary cCMV testing into a newborn hearing screening programme. METHODS: The study included three tertiary maternity hospitals in Queensland, Australia between August 2014 and April 2016. Infants who 'referred' on the newborn hearing screen were offered a salivary swab for CMV PCR at the point of referral to audiology. Swabs were routinely processed and tested for CMV DNA by real-time quantitative PCR. Parents of babies with a positive CMV PCR were notified, and the babies were medically assessed and, where appropriate, were offered treatment (oral valganciclovir). RESULTS: Of eligible infants, the parents of 83.0% (234/283) consented to the cCMV screen. Of these, 96.6% returned a negative result (226/234), and 3.4% (8/234) returned a positive result (three true positive; five false positive). The prevalence of cCMV for infants with confirmed hearing loss was 3.64% (P = 2/55; confidence interval = 0.44-12.53%). The cost comparison suggests the cost implementation of cCMV screening (and subsequent potential treatment benefits and management over time), compared to non-screening (and subsequent management), to be negligible. CONCLUSION: Incorporating cCMV testing into Universal Newborn Hearing Screening within Queensland is realistic and achievable, both practically and financially.

AIM: Haemophilus influenzae continues to cause invasive disease in children despite widespread Hib immunisation. The significance of non-B serotypes continues to be investigated, with evidence of increased invasive non-typeable H. influenzae (NTHi) world-wide. The aim of this study was to examine the current epidemiological and clinical features of invasive H. influenzae disease in children in Queensland, Australia. METHODS: A retrospective review was performed of all cases of invasive H. influenzae disease in children <18 years of age in Queensland between January 2002 and December 2011. Cases were identified from pathology records and data requested from treating hospitals. RESULTS: Laboratory data were obtained for 144 cases and clinical/demographic data for 123 cases. The majority (72%) of cases were children <5 years of age. Annual incidence rate for all children <5 years was 7.4/100 000, and for Aboriginal and Torres Strait Islander children <5 years was 10.2/100 000. Serotype was reported for 132 isolates, 69 NTHi and 63 encapsulated strains. The most common clinical diagnoses were pneumonia, meningitis and bacteraemia without clinical focus. Of the patients, 5 patients died, and 12 had significant morbidity at hospital discharge. CONCLUSIONS: While rates of invasive H. influenzae disease have decreased dramatically following the introduction of Hib vaccination, H. influenzae remains a cause of significant morbidity and mortality, and Aboriginal and Torres Strait Islander children remain particularly vulnerable.

OBJECTIVES: Viral respiratory infection is commonly considered a relative contraindication to elective cardiac surgery. We aimed to determine the frequency and outcomes of symptomatic viral respiratory infection in pediatric cardiac surgical patients. DESIGN: Retrospective cohort study of children undergoing cardiac surgery. Symptomatic children were tested using a multiplex Polymerase Chain Reaction (respiratory virus polymerase chain reaction) panel capturing nine respiratory viruses. Tests performed between 72 prior to and 48 hours after PICU admission were included. Mortality, length of stay in PICU, and intubation duration were investigated as outcomes. SETTING: Tertiary PICU providing state-wide pediatric cardiac services. PATIENTS: Children less than 18 years admitted January 1, 2008 to November 29, 2014 for cardiac surgery. MEASUREMENTS AND MAIN RESULTS: Respiratory virus polymerase chain reaction was positive in 73 (4.2%) of 1,737 pediatric cardiac surgical admissions, including 13 children with multiple viruses detected. Commonly detected viruses included rhino/enterovirus (48%), adenovirus (32%), parainfluenza virus 3 (10%), and respiratory syncytial virus (3%). Pediatric Index of Mortality 2, Aristotle scores, and cardiopulmonary bypass times were similar between virus positive and negative/untested cohorts. Respiratory virus polymerase chain reaction positive patients had a median 2.0 days greater PICU length of stay (p < 0.001) and longer intubation duration (p < 0.001). Multivariate analysis adjusting for age, Aristotle score, cardiopulmonary bypass duration, and need for preoperative PICU admission confirmed that virus positive patients had significantly greater intubation duration and PICU length of stay (p < 0.001). Virus positive patients were more likely to require PICU admission greater than 4 days (odds ratio, 3.5; 95% CI, 1.9-6.2) and more likely to require intubation greater than 48 hours (odds ratio, 2.5; 95% CI, 1.4-4.7). There was no difference in mortality. No association was found between coinfection and outcomes. CONCLUSIONS: Pediatric cardiac surgical patients with a respiratory virus detected at PICU admission had prolonged postoperative recovery with increased length of stay and duration of intubation. Our results suggest that postponing cardiac surgery in children with symptomatic viral respiratory infection is appropriate, unless the benefits of early surgery outweigh the risk of prolonged ventilation and PICU stay.

Non-typhoidal Salmonellae are a major cause of infectious diarrhoea worldwide and can cause invasive diseases, including bacteraemia, meningitis and osteomyelitis. Young or immunocompromised children and those with underlying conditions such as sickle cell disease are particularly vulnerable to invasive disease. There has been an increase in the rate of resistant non-typhoidal Salmonella, which is associated with invasive disease and hospitalisation. The intracellular nature of non-typhoidal Salmonella protects against extracellular antibiotics and can facilitate disease relapse, particularly meningitis. Effective antimicrobial agents with good intracellular penetration include azithromycin, fluoroquinolones and third-generation cephalosporins. Antibiotic treatment of non-typhoidal Salmonella gastroenteritis is only indicated if there are risk factors for invasive disease as it can prolong excretion and does not shorten the duration of gastrointestinal symptoms. Optimal choice and length of therapy for gastroenteritis and invasive disease in children is not clear. Here, we provide a review of the literature and treatment recommendations.

AIM: To investigate the proportion of children with moderate to profound hearing loss who have congenital cytomegalovirus (cCMV) infection. METHOD: Retrospective analysis of CMV dried blood spot (DBS) polymerase chain reaction (PCR) in children with moderate to profound hearing impairment referred to tertiary referral centres in Queensland. Participants were under 18 years old with no readily identified cause of hearing impairment, between 2008 and 2011. The primary outcome measure was DBS CMV PCR. Other outcome measures for cases referred to the Childhood Hearing Clinic (CHC) at the Mater Children's Hospital were level of hearing impairment and the neonatal hearing screen result. RESULTS: Of DBS CMV PCR testing for 106 children at the CHC for 2008 to 2011 inclusive, nine (8.5%) were positive (five with bilateral hearing impairment, four with unilateral hearing impairment). The prevalence of cCMV infection in children with moderate to profound hearing impairment was 8.4%, consistent with the statewide rate of 9.4% for 2008 to mid-2011. CONCLUSION: cCMV is a significant cause of hearing impairment in Queensland children. Investigation for cCMV by retrospective DBS CMV PCR should be part of the routine investigation of all babies and young children with hearing impairment. However early diagnosis is preferable and could be achieved by routine early screening of all newborns with hearing impairment for CMV before 3 weeks of age. The healthy hearing screening programme is a routine part of neonatal care. Enhancing the integration of screening for cCMV may reduce the current delays in diagnosis and should be evaluated.
RESUMO
Australian bat lyssavirus (ABLV) infection in humans is rare but fatal, with no proven effective therapy. ABLV infection can be prevented by administration of a post-exposure prophylaxis regimen of human rabies immunoglobulin and rabies vaccine. All Australian bats (flying foxes and microbats) should be considered to be carrying ABLV unless proven otherwise. Any bat-related injury (bite, scratch or mucosal exposure to bat saliva or neural tissue) should be notified immediately to the relevant public health unit - no matter how small the injury or how long ago it occurred. Human-to-human transmission of ABLV has not been reported but is theoretically possible. Standard infection control precautions should be employed when managing patients with suspected or confirmed ABLV infection.

OBJECTIVES: To describe antimicrobial use in hospitalised Australian children and to analyse the appropriateness of this antimicrobial use. DESIGN: Multicentre single-day hospital-wide point prevalence survey, conducted in conjunction with the Antimicrobial Resistance and Prescribing in European Children study. SETTING: Eight children's hospitals across five Australian states, surveyed during late spring and early summer 2012. PATIENTS: Children and adolescents who were inpatients at 8 am on the day of the survey. MAIN OUTCOME MEASURES: Quantity and quality of antimicrobial prescribing. RESULTS: Of 1373 patients, 631 (46%) were prescribed at least one antimicrobial agent, 198 (31%) of whom were < 1 year old. The highest antimicrobial prescribing rates were in haematology and oncology wards (76% [95/125]) and paediatric intensive care units (55% [44/80]). Of 1174 antimicrobial prescriptions, 550 (47%) were for community-acquired infections, 175 (15%) were for hospital-acquired infections and 437 (37%) were for prophylaxis. Empirical treatment accounted for 72% of antimicrobial prescriptions for community-acquired infections and 58% for hospital-acquired infections (395 and 102 prescriptions, respectively). A total of 915 prescriptions (78%) were for antibacterials; antifungals and antivirals were predominantly used for prophylaxis. The most commonly prescribed antibacterials were narrow-spectrum penicillins (18% [164 prescriptions]), ß-lactam-ß-lactamase inhibitor combinations (15% [136]) and aminoglycosides (14% [128]). Overall, 957 prescriptions (82%) were deemed appropriate, but this varied between hospitals (range, 66% [74/112]) to 95% [165/174]) and specialties (range, 65% [122/187] to 94% [204/217]). Among surgical patients, 65 of 187 antimicrobial prescriptions (35%) were deemed inappropriate, and a common reason for this was excessive prophylaxis duration. CONCLUSION: A point prevalence survey is a useful cross-sectional method for quantifying antimicrobial use in paediatric populations. The value is significantly augmented by adding assessment of prescribing quality.

BACKGROUND: Postoperative spinal implant infection following pediatric spinal surgery often presents a management dilemma. We aimed to characterize our experience in this cohort of patients, hoping to provide further insight when approaching these challenging cases. METHODS: A retrospective, observational study was performed of all children who underwent spinal surgery from January 2015 to June 2021 in a tertiary pediatric spinal surgery referral center in Queensland, Australia. Records were reviewed to identify cases of postoperative surgical site infection, with particular focus on children with infection directly involving implants. Preoperative prophylaxis, microbiology, clinical course and outcomes were analyzed. RESULTS: A total of 580 children underwent 933 procedures during the study period. The most common pathology requiring surgery was idiopathic scoliosis in 257 children (44.3%) followed by neuromuscular scoliosis in 192 children (33.1%). There were 35 cases of surgical site infection (6.03%), and 9 were implant-associated (1.55%). Infection rate among children with neuromuscular spinal deformity was almost 3-fold higher (11.5%) than idiopathic (3.89%). Methicillin-sensitive Staphylococcus aureus was the most commonly isolated organism (n = 15). Four implant-associated infections were successfully managed with retention of implant; all were diagnosed within 32 days (median = 20 days) and cultured either Staphylococcus aureus or Pseudomonas aeruginosa . Conversely, infections that necessitated implant removal had a more indolent onset (median = 175 days), and more often cultured Cutibacterium acnes and coagulase-negative Staphylococci . CONCLUSIONS: Postoperative spinal implant infection can be treated successfully with hardware retention in select cases. Earlier presentation and recognition appear to be associated with better rates of retention and are linked to certain organisms. Further exploration of specific preventative strategies may be key in preventing devastating late-onset infections.
