Detecting Mycobacterium tuberculosis Infection in Children Migrating to Australia.

In 2015, Australia updated premigration screening for tuberculosis (TB) disease in children 2-10 years of age to include testing for infection with Mycobacterium tuberculosis and enable detection of latent TB infection (LTBI). We analyzed TB screening results in children <15 years of age during November 2015-June 2017. We found 45,060 child applicants were tested with interferon-gamma release assay (IGRA) (57.7% of tests) or tuberculin skin test (TST) (42.3% of tests). A total of 21 cases of TB were diagnosed: 4 without IGRA or TST, 10 with positive IGRA or TST, and 7 with negative results. LTBI was detected in 3.3% (1,473/44,709) of children, for 30 applicants screened per LTBI case detected. LTBI-associated factors included increasing age, TB contact, origin from a higher TB prevalence region, and testing by TST. Detection of TB and LTBI benefit children, but the updated screening program's effect on TB in Australia is likely to be limited.

Etiology, Comorbidities, and Health Service Use in a Clinical Cohort of Children With Hearing Loss.

OBJECTIVE: To examine etiology, comorbidities, and health service use in a cohort of children with permanent hearing loss. Receiving an etiological diagnosis can inform reproductive planning, rehabilitation outcomes, predict additional disabilities, and direct intervention or management decisions. DESIGN: Retrospective audit of 518 deaf/hard-of-hearing children attending a tertiary pediatric outpatient clinic (2016-2019) using descriptive statistics. We used linear regression to investigate the relationship between degree of hearing loss, comorbidities, and health service use. RESULTS: Of the 518 children who attended the clinic, 481 (92.9%) proceeded with testing for etiology. Most children (399/518, 77.0%) were diagnosed with hearing loss by 3 mo of age. Of the children tested, the cause of hearing loss was confirmed in 234/481 (48.6%), suspected in 113/481 (23.5%), and unknown in 134/481 (27.9%); 17/341 (5.0%) had congenital cytomegalovirus (CMV), 17/320 (5.3%) had enlarged vestibular aqueducts, 67/213 (31.5%) of children with bilateral hearing loss had connexin mutation, and 25/72 (34.7%) of children with unilateral loss had hypoplastic/absent cochlear nerve on imaging. The odds of having a definitive/suspected diagnosis were twice as likely for indivduals with profound hearing loss than mild hearing loss (OR 2.1; 95% CI, 1.2-3.9; P = 0.02). The majority (348/518, 67.2%) of children had medical comorbidities, and most children attended otolaryngology (453/518, 87.5%), early intervention (358/518, 69.1%), and genetic (287/518, 55.4%) services. CONCLUSIONS: Children with hearing loss have diverse etiologies, most have comorbidities, and attend multiple services. Most families elected to proceed with diagnostic testing for etiology. Current guidelines and expanded access to genetic testing identified a confirmed/suspected etiological diagnosis in 72.1% of children tested. The number of comorbidities correlated with service use, regardless of hearing loss severity.

Outcomes of Children With Chronic Intestinal Failure: Experience Over 2 Decades at a Tertiary Paediatric Hospital.

BACKGROUND AND AIMS: The aim of the study was to aid decisions on prognosis and transplantation; this study describes the outcome of children with intestinal failure managed by the multidisciplinary intestinal rehabilitation program at the Royal Children's Hospital, Melbourne. METHODS: Retrospective review of children requiring parenteral nutrition (PN) for >3 months who were assessed for home PN between 1991 and 2011. RESULTS: A total of 51 children were included. Forty-two (82%) had short bowel syndrome (SBS), 5 (10%) had chronic intestinal pseudo-obstruction syndrome, and 4 (8%) had congenital enteropathies. Median small bowel length for patients with SBS was 45 cm (interquartile range 30-80) or 23.9% of the expected length for age (interquartile range 17.0%-40.6%). Overall survival rate was 84% (43/51). Mortality in children (n = 7) occurred after a median of 13.2 months (range 6.2-29.2) with intestinal failure-associated liver disease (IFALD) being the only predictor (P = 0.001). Out of 50 children 21 (42%) had IFALD. Children who were premature (P = 0.013), had SBS (P = 0.038), and/or frequent sepsis (P = 0.014) were more likely to develop IFALD. PN weaning occurred in 27 of 35 (77%) SBS survivors, after a median of 10.8 months (up to 8.2 years), with longer residual small bowel (P = 0.025), preservation of the ileocecal valve (P = 0.013) and colon (P = 0.011) being predictors. None of 5 (0%) patients with chronic intestinal pseudo-obstruction syndrome and 2 of 4 (50%) patients with congenital enteropathies weaned off PN. Overall sepsis rate was 7.3 episodes/1000 line days. Frequency of sepsis and longevity of central lines improved with time as patients grew older (both P < 0.001). CONCLUSIONS: Long-term PN with intestinal rehabilitation was effective in treating most children with intestinal failure. Children with severe refractory IFALD may have benefited from intestinal transplantation.

'I think we've had a health screen': New offshore screening, new refugee health guidelines, new Syrian and Iraqi cohorts: Recommendations, reality, results and review.

AIM: To examine refugee health assessments in Syrian and Iraqi children in the context of changes to offshore immigration screening, updated Australian refugee health guidelines and the primary care refugee health model in Victoria. METHODS: This is a retrospective audit of Syrian and Iraqi children aged 0-17 years attending a specialist immigrant health service from January 2015 to September 2017. RESULTS: We saw 128 children (7 months-16 years, 64.8% male). Prior to arrival, 58.9% of children had experienced trauma, and 67.9% had missed at least 1 year of school. Almost all children (93.3%) were linked with a regular general practitioner in Australia, and 23.6% children were linked with a refugee health nurse; offshore health records were infrequently available. Of school-aged children, 25% were not enrolled in school 3 months after arrival. Only 2 of 113 (1.8%) children had completed a recommended refugee health assessment, and 55.1% had commenced appropriate catch-up vaccination in primary care. After screening completion, the most prevalent conditions were low vitamin D (63.6%); growth/nutrition (24.2%), neurological/metabolic (16.4%), learning/behaviour (15.6%) and mental health (12.5%) concerns; latent tuberculosis infection (11.8%); and developmental delay (10.2%). Sixteen children required surgery after arrival, and six children had life-threatening medical conditions on arrival - only one had an offshore critical alert; care for the other five children resulted in 133 unanticipated hospital admission days. CONCLUSIONS: There are substantial challenges with the current primary care screening model in Victoria. Disability, developmental and mental health concerns were prominent in this cohort, and many children had delays in education access, compounding prior disadvantage.

No jab, no record: Catch-up vaccination of children in immigration detention.

International Health and Medical Services (IHMS) are contracted to provide health services, including catch-up vaccination, for individuals in immigration detention. Our audit of catch-up vaccination in asylum seeker children who spent time in held detention demonstrates inadequate and suboptimal vaccine delivery in this setting, and no evidence that IHMS recorded vaccines on the Australian Childhood Immunisation Register at the time. We also found substantial shortfalls in vaccination for these children after they were released from detention. Immunisation in this cohort falls well below Australian community standards, does not demonstrate assurance in IHMS provision of care, and has implications for similar asylum seeker cohorts nationally as well as people in held detention.

The Australasian Society for Infectious Diseases and Refugee Health Network of Australia recommendations for health assessment for people from refugee-like backgrounds: an abridged outline.

INTRODUCTION: In 2009, the Australasian Society of Infectious Diseases published guidelines on the post-arrival health assessment of recently arrived refugees. Since then, the number of refugees and asylum seekers reaching Australia has increased substantially (17 555 refugees in 2015-16) and the countries of origin have changed. These groups are likely to have had poor access to health care pre-arrival and, consequently, are at risk of a range of chronic and infectious diseases. We established an advisory group that included infectious diseases physicians, general practitioners, public health specialists, paediatricians and refugee health nurses to update the 2009 guidelines.Main recommendations: All people from refugee-like backgrounds, including children, should be offered a tailored comprehensive health assessment and management plan, ideally within 1 month of arrival in Australia. This can be offered at any time if initial contact with a GP or clinic is delayed. Recommended screening depends on history, examination and previous investigations, and is tailored based on age, gender, countries of origin and transit and risk profile. The full version of the guidelines is available at http://www.asid.net.au/documents/item/1225.Changes in management as a result of this guideline: These guidelines apply to all people from refugee-like backgrounds, including asylum seekers. They provide more information about non-communicable diseases and consider Asia and the Middle East as regions of origin as well as Africa. Key changes include an emphasis on person-centred care; risk-based rather than universal screening for hepatitis C virus, malaria, schistosomiasis and sexually transmissible infections; updated immunisation guidelines; and new recommendations for other problems, such as nutritional deficiencies, women's health and mental health.

Gaps in smiles and services: a cross-sectional study of dental caries in refugee-background children.

BACKGROUND: Refugees are reported to experience high rates of dental disease, although there are limited data on refugee children. The aim of this study was to report on oral health in refugee-background children in Australia, and to assess their follow-up at dental services. METHODS: Cross-sectional study of opportunistic oral health screening and subsequent dental service use in refugee-background children attending a refugee health clinic in Victoria, Australia, between November 2006-November 2010. RESULTS: 350 patients (0-18 years, mean age 8 years 7 months) had oral health screening; 241 (68.9%) were born overseas, (176 Africa, 65 other countries) and 109 (31.1%) were born in Australia to African-background families. Parents were concerned about oral health in 65/341 (19.1%) children, with specific concern about caries in only 9/341 (2.6%). On assessment, 155/336 (46.1%) had visible caries and 178/345 (51.6%) had caries experience (dmft/DMFT > 0). Where parents were concerned about caries, they were likely to be present (positive predictive value = 100%), however absence of parent concern about caries was not reassuring (negative predictive value = 56.1%).Compared to Australian-born children of African background; African-born children were more likely to be referred for further dental care (adjusted PR 1.33, 95% CI [1.02-1.73]), although there was no statistically significant difference in caries prevalence. African-born children were less likely to have caries compared to other overseas-born children (adjusted PR 0.73, 95% CI [0.58 - 0.93]). Overall 187/344 (54.4%) children were referred for further dental care; 91/124 (73.4%) attended any dental appointment. Attendance rates were 90% with a phone reminder system for appointments, attendance reduced when this system lapsed. CONCLUSIONS: Oral health is an important public health issue in refugee-background children, despite low levels of parent concern and very few parent reported caries. Routine direct oral health assessment is important in refugee-background children and co-ordinated health systems may help improve their attendance at dental services.

Learning difficulties or learning English difficulties? Additional language acquisition: an update for paediatricians.

Australia is a diverse society: 26% of the population were born overseas, a further 20% have at least one parent born overseas and 19% speak a language other than English at home. Paediatricians are frequently involved in the assessment and management of non-English-speaking-background children with developmental delay, disability or learning issues. Despite the diversity of our patient population, information on how children learn additional or later languages is remarkably absent in paediatric training. An understanding of second language acquisition is essential to provide appropriate advice to this patient group. It takes a long time (5 years or more) for any student to develop academic competency in a second language, even a student who has received adequate prior schooling in their first language. Refugee students are doubly disadvantaged as they frequently have limited or interrupted prior schooling, and many are unable to read and write in their first language. We review the evidence on second language acquisition during childhood, describe support for English language learners within the Australian education system, consider refugee-background students as a special risk group and address common misconceptions about how children learn English as an additional language.

Resilience and Positive Wellbeing Experienced by 5-12-Year-Old Children with Refugee Backgrounds in Australia: The Childhood Resilience Study.

Refugee research tends to be deficit based and focused on the risks threatening positive adaptation and wellbeing. High rates of mental (and physical) health issues have been reported for refugee adults and children, including intergenerational trauma. This study uses the new Child Resilience Questionnaire (CRQ), co-designed with refugee background communities, to describe resilience and positive wellbeing experienced by children of refugee-background. The Childhood Resilience Study (CRS) recruited 1132 families with children aged 5-12 years in Victoria and South Australia, Australia. This included the recruitment of 109 families from 4 refugee background communities: Assyrian Chaldean (Iraq, Syria), Hazara (Afghanistan), Karen (Burma, Thailand) and Sierra Leonean families. CRQ-parent/caregiver report (CRQ-P/C) scores were categorised into 'low', 'moderate' and 'high'. The child's emotional and behavioural wellbeing was assessed with the Strengths and Difficulties Questionnaire, with positive wellbeing defined as <17 on the total difficulties score. Tobit regression models adjusted for a child's age. The CRQ-P/C scores were not different for boys and girls of refugee background. Children of refugee-background (n = 109) had higher average CRQ-P/C scores than other CRS children (n = 1023) in the personal, school and community domains, but were lower in the family domain. Most children with 'high' resilience scores had positive wellbeing for both children of refugee-background (94.6%) and other CRS children (96.5%). Contrary to common stereotypes, children of refugee-background show specific individual, family, school and cultural strengths that can help them navigate cumulative and complex risks to sustain or develop their positive wellbeing. A better understanding as to how to build strengths at personal, family, peer, school and community levels where children are vulnerable is an important next step. Working in close collaboration with refugee communities, schools, policy makers and key service providers will ensure the optimal translation of these findings into sustainable practice and impactful public policy.

Balancing the risks and benefits of sun exposure: A revised position statement for Australian adults.

OBJECTIVE: To describe the development of a new position statement regarding balancing the risks and benefits of sun exposure for Australian adults. METHODS: We conducted a Sun Exposure Summit in March 2021, with presentations from invited experts and a workshop including representation from academic, clinical, policy, and patient stakeholder organisations. The group considered advice about balancing the risks and benefits of sun exposure for Australian adults and developed a revised consensus position statement. RESULTS: The balance of risks and benefits of sun exposure is not the same for everybody. For people at very high risk of skin cancer, the risks of exposure likely outweigh the benefits; sun protection is essential. Conversely, people with deeply pigmented skin are at low risk of skin cancer but at high risk of vitamin D deficiency; routine sun protection is not recommended. For those at intermediate risk of skin cancer, sun protection remains a priority, but individuals may obtain sufficient sun exposure to maintain adequate vitamin D status. CONCLUSIONS: The new position statement provides sun exposure advice that explicitly recognises the differing needs of Australia's diverse population. IMPLICATIONS FOR PUBLIC HEALTH: Mass communication campaigns should retain the focus on skin cancer prevention. The new position statement will support the delivery of personalised advice.

Vitamin D and health in pregnancy, infants, children and adolescents in Australia and New Zealand: a position statement.

• The recommended level for serum 25-hydroxyvitamin D (25(OH)D) in infants, children, adolescents and during pregnancy and lactation is ≥ 50 nmol/L. This level may need to be 10-20 nmol/L higher at the end of summer to maintain levels ≥ 50 nmol/L over winter and spring. • Sunlight is the most important source of vitamin D. The US recommended dietary allowance for vitamin D is 600 IU daily in children aged over 12 months and during pregnancy and lactation, assuming minimal sun exposure. • Risk factors for low vitamin D are: lack of skin exposure to sunlight, dark skin, southerly latitude, conditions affecting vitamin D metabolism and storage (including obesity) and, for infants, being born to a mother with low vitamin D and exclusive breastfeeding combined with at least one other risk factor. • Targeted measurement of 25(OH)D levels is recommended for infants, children and adolescents with at least one risk factor for low vitamin D and for pregnant women with at least one risk factor for low vitamin D at the first antenatal visit. • Vitamin D deficiency can be treated with daily low-dose vitamin D supplements, although barriers to adherence have been identified. High-dose intermittent vitamin D can be used in children and adolescents. Treatment should be paired with health education and advice about sensible sun exposure. Infants at risk of low vitamin D should be supplemented with 400 IU vitamin D3 daily for at least the first year of life. • There is increasing evidence of an association between low vitamin D and a range of non-bone health outcomes, however there is a lack of data from robust randomised controlled trials of vitamin D supplementation.

B alert: hepatitis B virus infection in children in Victoria.

AIM: The aim of this study is to determine the demographic, clinical and serological patterns of hepatitis B in children in Victoria over a 17-year period. METHODS: Retrospective analysis of medical records of all patients <18 years of age with positive hepatitis B surface antigen referred to the Gastroenterology, Immigrant Health and Infectious Diseases clinics between 1992 and 2009. RESULTS: Of the 164 children identified, 76% were born overseas, with vertical transmission the most likely source in 84%. Most were asymptomatic, with no signs of chronic liver disease. Forty children infected with hepatitis B virus (HBV) were born in Australia prior to universal vaccination. There was poor documentation of vaccination or response to vaccination in siblings at risk within families where at least one child was infected. An increasing number of referrals was noted from 2006 to 2009 compared with the preceding 4 years (P < 0.001). Of an expected 200 follow-up visits from new referrals, 78% were attended. CONCLUSION: These findings suggest that the number of children with HBV in our population is increasing and that models of health care designed to integrate primary with specialist care are required to minimise the overall health care burden of this chronic infection.

Refugee child health: a systematic review of health conditions in children aged 0-6 years living in high-income countries.

This study describes the extent, quality and cultural appropriateness of current research on the health conditions of refugee children aged 0-6 years settled in high-income countries. A systematic review was conducted, including original articles published on the health conditions experienced by refugee children. A total of 71 papers were included. The studies varied considerably in their research design, population characteristics and health conditions. Studies included information on 37 different health conditions, with the majority non-communicable diseases, in particular growth, malnutrition and bone density. Although the studies identified a wide range of health issues, a coordinated effort to prioritise research on particular health topics was lacking, and health conditions studied do not align with the global burden of disease for this population. Additionally, despite being rated medium-high quality, most studies did not describe measures taken to ensure cultural competency and community involvement in their research. We suggest a coordinated research effort for this cohort, with greater emphasis on community engagement to improve the evidence-base of the health needs of refugee children after settlement.

Health of children who experienced Australian immigration detention.

BACKGROUND: Australian immigration policy resulted in large numbers of children being held in locked detention. We examined the physical and mental health of children and families who experienced immigration detention. METHODS: Retrospective audit of medical records of children exposed to immigration detention attending the Royal Children's Hospital Immigrant Health Service, Melbourne, Australia, from January 2012 -December 2021. We extracted data on demographics, detention duration and location, symptoms, physical and mental health diagnoses and care provided. RESULTS: 277 children had directly (n = 239) or indirectly via parents (n = 38) experienced locked detention, including 79 children in families detained on Nauru or Manus Island. Of 239 detained children, 31 were infants born in locked detention. Median duration of locked detention was 12 months (IQR 5-19 months). Children were detained on Nauru/Manus Island (n = 47/239) for a median of 51 (IQR 29-60) months compared to 7 (IQR 4-16) months for those held in Australia/Australian territories (n = 192/239). Overall, 60% (167/277) of children had a nutritional deficiency, and 75% (207/277) had a concern relating to development, including 10% (27/277) with autism spectrum disorder and 9% (26/277) with intellectual disability. 62% (171/277) children had mental health concerns, including anxiety, depression and behavioural disturbances and 54% (150/277) had parents with mental illness. Children and parents detained on Nauru had a significantly higher prevalence of all mental health concerns compared with those held in Australian detention centres. CONCLUSION: This study provides clinical evidence of adverse impacts of held detention on children's physical and mental health and wellbeing. Policymakers must recognise the consequences of detention, and avoid detaining children and families.

East African immigrant children in Australia have poor immunisation coverage.

AIM: To provide data on the immunisation status of recently arrived East African children and adolescents in Australia. METHODS: A prospective audit was conducted at a hospital-based paediatric immigrant health clinic, in Melbourne, Australia, over the time period November 2000-January 2002. Study subjects were consecutive children and adolescents born in East Africa, arriving in Australia after January 1998. Vaccination status was ascertained by parent report and review of patient-held records where available, and by serological testing for immunity to hepatitis B, tetanus, diphtheria, rubella and measles. RESULTS: Among 136 participants, 132 (97%) had incomplete or unknown immunisation status based on parent report and vaccination records; written records were available for 5/136 (4%) of participants. Only 21/136 (15%) had serological immunity to all five of measles, rubella, tetanus, diphtheria and hepatitis B, despite a total of 395 visits to vaccine providers by participants since migration. A higher proportion of children had serological immunity to measles (90%) compared to the proportion with serological immunity to rubella (77%), tetanus (61%), diphtheria (45%) and hepatitis B (33%). The predictive value of parent-reported vaccination status for serological immunity was poor. CONCLUSIONS: Paediatric East African immigrants in Victoria are very likely to be inadequately immunised and parent-reported vaccination status does not predict serological immunity. Full catch-up immunisation is recommended where immunisation status is unknown and written records are unavailable. Consideration should be given to policy and program development to provide timely and complete immunisation coverage in this group after arrival in Australia.

Health service delivery for newly arrived refugee children: a framework for good practice.

AIM: To propose a framework for good practice to promote improved access, equity and quality of care in service delivery for newly arrived refugee children. METHODS: Development of a framework based on national and international literature and current service models in Australian paediatric refugee health. RESULTS: Ten elements of a framework for good practice were identified: comprehensive health screening; coordination of initial and ongoing health care; integration of physical, developmental and psychological health care; consumer participation; culturally and linguistically appropriate service provision; intersectoral collaboration; accessible and affordable services and treatments; data collection and evaluation to inform evidence-based practice; capacity building and sustainability; and advocacy. CONCLUSIONS: High-quality care can be achieved through a range of service models. The elements identified provide a framework for evaluating current services and for planning future service development. The framework for good practice can be applied to facilitate improvements in refugee health care and to reduce the gap between health needs and currently available services.
