    Abstract Objective: Prior experience of an adverse event following immunisation is a known barrier to vaccination. Limited Australian data evaluating adverse event recurrence among children exists to inform clinical decisions. We aimed to assess adverse event following immunisation recurrence among children with prior adverse events and to evaluate if family history increased adverse event risk.
    Methods: A prospective cohort study was conducted from March 3rd until August 18th, 2023. Children ≤ 16 years with prior adverse events following immunisation in themselves or family were recruited from specialist immunisation clinics at two quaternary paediatric hospitals. Adverse event outcomes were collected via surveys administered at presentation, three, and eight days post vaccination, and analysed by key characteristics and potential risk factors.
    Results: Forty three of forty nine (43/49, 87.8 %) children enrolled received further vaccines. Of those who completed the follow up surveys, 50.0 % (16/32) reported an adverse event. Recurrence of prior adverse events occurred for 23.3 % (10/43, 95 % CI: 11.8 % - 38.6 %) of the cohort. Two of twelve (2/12, 16.7 %) participants with prior serious adverse events who received further vaccines reported a serious adverse event recurrence. No post review serious adverse events were observed in children with prior non serious adverse events. Neurological conditions were a risk factor for prior (neurological condition 3/3 versus no neurological condition 2/40, p < 0.001) and post review (neurological condition 2/3 versus no neurological condition 0/28, p = 0.006) post vaccination seizures. Family history had no relationship to post review adverse events (family history 5/8 versus no family history 11/23, p = 0.685).
    Conclusion: Revaccination is safe for the majority of children with a personal or family history of adverse event following immunisation.

    Abstract Background: Ventilator-associated pneumonia (VAP) caries a morbidity and mortality risk in the preterm neonate, particularly in the context of rising global antimicrobial resistance driving infections due to multidrug-resistant Gram-negative bacteria. Cefiderocol, a siderophilic cephalosporin, has broad Gram-negative antimicrobial activity and central nervous system penetration and is used for the treatment of hospital-acquired pneumonia or VAP in adults. Scarce data exists on its use in neonates.
    Case: A female neonate born at 26 + 6 weeks developed VAP at 21 days of life. She was commenced on corticosteroids, vancomycin and ceftazidime but continued to deteriorate. Sputum cultures yielded Stenotrophomonas maltophilia resistant to trimethoprim/sulfamethoxazole, ciprofloxacin and ceftazidime, with potential susceptibility to cefiderocol. Cerebrospinal fluid showed an elevated white cell count. In view of worsening respiratory and hemodynamic status, antibiotic treatment was changed to cefiderocol monotherapy at 30 mg/kg/dose every 8 hours. Within 72 hours of commencing cefiderocol, the neonate was successfully extubated to variable-flow continuous positive airway pressure and showed ongoing clinical improvement.
    Conclusions: Cefiderocol was integral for the care of our neonate without any immediate adverse safety consequences. We relied on dosing data from a conference abstract, due to the paucity of evidence on the use of novel antimicrobials. This lack of evidence is particularly concerning given preterm neonates are particularly vulnerable to infections with multidrug-resistant Gram-negative organisms due to their immature immune systems, prolonged hospital stay, repeated interventions and antimicrobial exposure.

    Abstract Background: Pathogenic viruses have been abundant and diverse in wastewater, reflecting the pattern of infection in humans. Human feces, urine, and perhaps other washouts that frequently circulate in sewage systems may contaminate wastewater with SARS-CoV-2. It's crucial to effectively disinfect wastewater since poorly handled wastewater could put the population at risk of infection.
    Aims: To emphasize the presence and spread of SARS-CoV-2 in sewage (wastewater) through viral shedding from the patients to detect the virus in the population using wastewater-based epidemiology. Also, to effectively manage the transmission of SARS-CoV-2 and reduce the spread of the virus in the population using disinfectants is highlighted.
    Methods: We evaluated articles from December 2019 to August 2022 that addressed SARS-CoV-2 shedding in wastewater and surveillance through wastewater-based epidemiology. We included the papers on wastewater disinfection for the elimination of SARS-CoV-2. Google Scholar, PubMed, and Research4Life are the three electronic databases from which all of the papers were retrieved.
    Results: It is possible for viral shedding to get into the wastewater. The enumeration of viral RNA from it can be used to monitor virus circulation in the human community. SARS-CoV-2 can be removed from wastewater by using modern disinfection techniques such as sodium hypochlorite, liquid chlorine, chlorine dioxide, peracetic acid, and ultraviolet light.
    Conclusion: SARS-CoV-2 burden estimates at the population level can be obtained via longitudinal examination of wastewater, and SARS-CoV-2 can be removed from the wastewater through disinfection.

    Abstract Background: An impacted tooth is a tooth which does not reach the occlusal plane even after two-thirds root formation. Conditions associated with impacted teeth include trismus, cystic lesions, and cervical caries of second molars. The objective of this study was to evaluate the occurrence of carious lesions in the distal aspect of the mandibular second molar and its association with the presence of mandibular third molars.
    Methods: A cross-sectional study was conducted from September 2018 to September 2020. Approval was taken from the Institutional Review Committee with reference number 90/77/78. Orthopantomograms of patients aged 18 years or older were studied. Information on age, gender, mandibular second and third molars were recorded. Convenient sampling was done. Statistical analysis was done using Statistical Package for Social Sciences version 21.
    Results: A total of 626 radiographs were studied of which mesioangular impaction (35.3%) was the most prominent type and followed by horizontal impaction, causing distal caries in second molars. The age group between 20-40 years and female gender had the higher prevalence of distal caries in second molar teeth. There was a significant correlation between gender and cavity existence (p=0.00), between impaction and existence of decay (p=0.00), and depth of impaction with cavity formation (p=0.004).
    Conclusions: A total of 31.8% of the patients with impacted mandibular third molars had distal cervical caries in second molars. Mesioangular type, female gender, type A were the prominent factors associated with distal caries in second molar teeth due to impacted third molars.
