    Rehabilitation is thought to reduce ataxia severity in individuals with hereditary cerebellar ataxia (HCA). This multicenter, randomized controlled superiority trial aimed to examine the efficacy of a 30-week goal-directed rehabilitation program compared with 30 weeks of standard care on function, ataxia, health-related quality of life, and balance in individuals with an HCA.Individuals with an autosomal dominant or recessive ataxia (aged ≥15 years) were enrolled at 5 sites in Australia. Participants were randomized (1:1) to receive rehabilitation (6 weeks of outpatient physiotherapy followed by a 24-week home exercise program) (n = 39) or continued their usual activity (n = 37). The primary outcome measure was the motor domain of the Functional Independence Measure (mFIM) at 7 weeks. Secondary outcomes included the Scale for the Assessment and Rating of Ataxia (SARA) and the SF-36v2, assessed at 7, 18, and 30 weeks. Outcome assessors were blinded to treatment allocation.Seventy-one participants (rehabilitation, 37; standard-care, 34) were included in the intention-to-treat analysis. At 7 weeks, mFIM (mean difference 2.26, 95% confidence interval [CI]: 0.26 to 4.26, p = 0.028) and SARA (-1.21, 95% CI: -2.32 to -0.11, p = 0.032) scores improved after rehabilitation compared with standard care. Compared with standard care, rehabilitation improved SARA scores at 30 weeks (mean difference -1.51, 95% CI: -2.76 to -0.27, p = 0.017), but not mFIM scores (1.74, 95% CI: -0.32 to 3.81, p = 0.098). Frequent adverse events in both groups were fatigue, pain, and falls.Goal-directed rehabilitation improved function at 7 weeks, with improvement in ataxia and health-related quality of life maintained at 30 weeks in individuals with HCA, beyond that of standard care.

    Adverse reactions to trimethoprim/sulfamethoxazole for melioidosis eradication therapy: an evaluation of frequency and risk factors.
    Trimethoprim/sulfamethoxazole is the first-line agent for oral eradication therapy for melioidosis but has been associated with toxicity in this context. This study aimed to quantify adverse drug reactions (ADRs) to trimethoprim/sulfamethoxazole when used for treatment of melioidosis, and assess risk factors for ADR development. A retrospective review of antimicrobial associated ADRs was performed in all patients treated for melioidosis in the Northern Territory of Australia from January 2017 - September 2022. Over this time, 268 treatment episodes from 256 individuals were included. The frequency of clinician-attributed ADRs to trimethoprim/sulfamethoxazole (51% of exposed) was higher than for other antimicrobials used (ceftazidime 12%, meropenem 8% and doxycycline 12% of those exposed; p<0.0001). 44% of those treated with trimethoprim/sulfamethoxazole required drug cessation or dose reduction and 5 individuals (2%) had a severe cutaneous adverse reaction, with one fatality. Acute kidney injury was the most frequent ADR (25% of those exposed), with age and pre-existing renal disease independently associated with its development. Here we report very high rates of ADRs attributed to trimethoprim/sulfamethoxazole resulting in frequent discontinuation of this drug as part of oral eradication therapy for melioidosis. Further work is needed to balance the necessity and toxicity of this drug in this clinical context.

    Post mortem damage by predators varies with geography, climate, and location of cadavers. Frequently encountered facultatively parasitic terrestrial organisms include fly larvae (maggots), ants and beetles. This report describes for the first time opportunistic post mortem damage caused by the terrestrial flatworm Platydemus manokwari de Beauchamp,1963 (New Guinea Flatworm) (phylum Platyhelminthes: order Tricladida: suborder Continenticola: family Geoplanidae) to exposed skin of a body located in a tropical urban location. Several flatworms were attached to the body associated with areas of skin loss. Microscopy showed epidermal damage with no vital reaction and the presence of PAS-positive granules consistent with flatworm secretions. No human DNA profile was recovered with genetic testing of two of the flatworms. This case extends the range of potential post mortem predators to include flatworms, albeit opportunistically.

    Feasibility of latent tuberculosis infection diagnosis by interferon-γ release assay remote from testing facilities.

    Although the tuberculin skin test (TST) has been the mainstay of the diagnosis of latent tuberculosis infection (LTBI) for many decades, interferon-gamma release assays (IGRAs) are gaining acceptance and are more specific for this diagnosis. The characteristics of one such IGRA, the QuantiFERON-TB Gold Whole Blood In-Tube, make it feasible for use in a remote setting. This study performed 62 IGRAs with this test on individuals testing positive by TST, in a clinical setting over 3,000 km from the testing laboratory. Of these, 42 patients (68%) recorded negative results, 19 (31%) were positive, with only 1 result (2%) indeterminate. Negative, and therefore discordant in this study, test results were more common in those known to have been previously vaccinated with bacille Calmette-Guérin. These results are consistent with other reports, indicating that this approach to testing is logistically feasible, and has the potential to complement LTBI screening to assist tuberculosis control programs in settings remote from the testing laboratory.

    Paediatric Strongyloidiasis in Central Australia.

    Few published studies are available describing the prevalence of paediatric strongyloidiasis in endemic areas within Australia. This literature review and exploratory clinical audit presents the first seroprevalence data for paediatric patients in Central Australia. A total of 16.1% (30/186) of paediatric inpatients tested for in 2016 were seropositive (95% CI: 11.5% to 22.1%). Eosinophilia of unknown aetiology was the most common indication for testing (91.9%). Seropositive patients were significantly more likely to reside in communities outside of Alice Springs ( = 0.02). Seropositive patients were noted to have higher mean eosinophil counts with a mean difference of 0.86 × 10⁸/L (95% CI: 0.56 to 1.16, < 0.0001), although the limited utility of eosinophilia as a surrogate marker of strongyloidiasis has been described previously. All seropositive patients were Indigenous. There was no significant difference in ages between groups. There was a male predominance in the seropositive group, although this was not significant ( = 0.12). Twelve patients had known human T-lymphotropic virus 1 (HTLV-1) status and all were seronegative. Further research describing the epidemiology of strongyloidiasis in Central Australia is required.
