    Abstract Purpose: To present our experience of paediatric blepharoptosis in a tertiary referral centre and evaluate the effectiveness of surgical intervention.
    Methods: A retrospective cohort study of all children receiving surgical blepharoptosis correction between 1/1/10 and 29/2/16. Children with pre-operative levator function (LF) ≥ 7 mm received levator resection, those with LF ≤ 4 mm received brow suspension, and in those children with LF of 5-6 mm, either levator resection or brow suspension was chosen depending on the degree of frontalis recruitment.
    Results: Ninety-five children (109 eyes, 64 boys) underwent blepharoptosis surgery within the study period. Mean (range) age at surgery was 5.9 (1.2-12.5) years. Seventy-nine (83.2%) had simple levator maldevelopment. Fifteen children were excluded due to inadequate follow-up. Of the remaining 80 children, 41 (51.2%) underwent levator resection, 27 (33.8%) underwent fascia lata brow suspension, and twelve (15.0%) underwent mersilene mesh brow suspension. Margin reflex distance-1 was greatest at 6-week follow-up with a small "lid drop" by 6-month follow-up in both the levator resection (0.9 mm pre-operatively, 3.1 mm at 6-week follow-up, 2.6 mm at 6-month follow-up) and fascia lata brow suspension (0.3 mm, 2.5 mm, 2.2 mm) groups. No immediate complications, and only two serious post-operative complications, were noted. One case of residual blepharoptosis was re-operated (fascia lata brow suspension).
    Conclusions: Surgical correction of paediatric blepharoptosis is safe and, after an observed lid drop between 6-week and 6-month follow-up (not seen in the mersilene mesh brow suspension group), effect appears to be maintained to 6 months and beyond. Readily accessible orthoptic assessment would help identify children at risk of amblyopia, both pre-operatively and post-operatively.

    Abstract Background: Orbital exenteration is a radical surgical procedure resulting in deformity. It involves removal of the globe, optic nerve, extra-ocular muscles, orbital fat, lacrimal gland, and peri-osteum. Sino-orbital fistula (SOF) formation is a common documented post-operative complication, usually connecting the orbit and the ethmoid sinus. SOFs can cause leaks of serous fluid, and act as an entry site for pathogens into the orbit leading to socket infection and breakdown.
    Methods: This retrospective study analyzed exenterations performed over a 22-year period (1993-2015) at the National Ocular Oncology Service Centre for Scotland. PDS is a crystalline, biodegradable polyether-ester that is strong with good shape-memory and flexibility. Orbital exenterations with and without the use of PDS foil were compared in terms of SOF formation.
    Results: A total of 30 exenterations were performed during the study period. A total of 29 were analyzed. Choroidal malignant melanoma was the most common indication for performing orbital exenteration (n = 7, 24.14%). The most common post-operative complications seen were SOF (n = 8, 27.59%). A total of 8 out 21 (38.10%) cases not using PDS developed SOFs. By contrast, none of nine patients receiving PDS plates developed SOFs (p = 0.0332).
    Conclusions: This is the first study to compare SOF rate in patients undergoing exenteration with and without the use of PDS foil. PDS foil is a safe material, which has effectively reduced the incidence of SOF formation.

    Abstract Objective: To examine cognitive intraindividual variability (IIV) dispersion as a predictor of everyday functioning and mortality in persons who are homeless or precariously housed.
    Method: Participants were 407 community-dwelling adults, followed for up to 13 years. Neurocognition was assessed at baseline and IIV dispersion was derived using a battery of standardized tests. Functional outcomes (social, physical) were obtained at baseline and last follow-up. Mortality was confirmed with Coroner's reports and hospital records (
    Results: Higher IIV dispersion predicted poorer current physical functioning (
    Conclusions: Our findings suggest that indices of neurocognitive functioning (i.e. IIV dispersion and global cognition) may be differentially related to discrete dimensions of functional outcomes in an at-risk population. IIV dispersion may be a complimentary marker of emergent physical health dysfunction in precariously housed adults and may be best used in conjunction with traditional neuropsychological indices.

    Abstract Background/objectives: The Scottish Ocular Oncology Service (SOOS) manages all patients with uveal melanoma (UM) in Scotland. Our aim was to determine the long-term all-cause and cause-specific survival of patients with UM, irrespective of treatment modality.
    Subjects/methods: A retrospective single-centre cohort study including all patients diagnosed with UM by the SOOS between 1/1/1998 and 31/12/2002. Data from the SOOS database were correlated with death records held by National Records of Scotland, which provided date, and all listed causes, of death for all deceased patients.
    Results: Two hundred and eighteen patients were newly diagnosed with UM between 1/1/1998 and 31/12/2002. One hundred and fifteen (52.8%) were female. The mean (median) age at diagnosis was 63(65) years (range: 16-89). Of 179 choroidal melanomas, melanoma-specific survival was 92.3%, 87.4% and 83.8% at 5, 10 and 15 years, respectively. Cancer-specific survival was 85.8%, 71.8% and 62.3%. All-cause survival was 81.6% (146/179), 62.0% (111/179) and 46.7% (computed, fraction inexpressible). Of 26 ciliary body melanomas, melanoma-specific survival was 87.2%, 81.3% and 81.3% at 5, 10 and 15 years. Cancer-specific survival was 62.9%, 40.6% and 40.6%. All-cause survival was 61.5% (16/26), 38.5% (10/26) and 26.9% (7/26). Of 13 iris melanomas, at all three timepoints (5/10/15 years), melanoma-specific survival was 100%, cancer-specific survival was 92.3%, and all-cause survival was 76.9% (10/13).
    Conclusions: Correlation of SOOS and national records survival data confirms 15-year melanoma-specific survival of 83.8%, 81.3% and 100% for choroidal, ciliary body and iris melanomas, respectively. We can now provide accurate survival data to our patients in Scotland.

    Abstract Objective: Many individuals living in precarious housing or homelessness have multimorbid illnesses, including substance use, psychiatric, and neurological disorders. Movement disorders (MDs) associated substance use are amongst the poorly studied subtopics of drug-induced MDs. The aim of the present study was, therefore, to determine the proportion affected and severity of different signs of MDs, as well as their associations with substance use in a community-based sample of precariously housed and homeless individuals.
    Methods: Participants were recruited from an impoverished urban neighborhood and were assessed for substance dependence and self-reported substance use (alcohol, cannabis, cocaine, methamphetamine, nicotine, and opioids), as well as for the severity of signs of MDs (akathisia, dyskinesia, dystonia, and parkinsonism). Adjusted regression models were used to estimate the associations of the severity of signs with the frequency of substance use over the past 4 weeks and with the baseline diagnosis of substance dependence.
    Results: The proportion of the sample with clinically relevant signs of MDs in any of the four categories was 18.6% (n = 401), and these participants demonstrated lower levels of functioning than those without signs. Of the different types of substance use, only methamphetamine (its frequency of use and dependence) was significantly associated with greater severity of overall signs of MDs. Frequency of methamphetamine use significantly interacted with age and sex, whereby older female participants exhibited the greatest overall severity with increased methamphetamine use. Of the different signs of MDs, methamphetamine use frequency was positively associated with the severity of trunk/limb dyskinesia and hypokinetic parkinsonism. Relative to no use, concurrent use of antipsychotics demonstrated lower severity of trunk/limb dyskinesia and greater severity of hypokinetic parkinsonism with methamphetamine use, and greater severity of dystonia with cocaine use.
    Conclusions: Our study found a high proportion of MDs in a relatively young sample, and their severity was consistently associated with methamphetamine use, moderated by participant demographics and antipsychotic use. These disabling sequelae represent an important and understudied neurological condition that may affect quality of life and will require further study.

    Abstract Housing insecurity is associated with co-occurring depression and pain interfering with daily activities. Network analysis of depressive symptoms along with associated risk or protective exposures may identify potential targets for intervention in patients with co-occurring bodily pain. In a community-based sample of adults (n = 408) living in precarious housing or homelessness in Vancouver, Canada, depressive symptoms were measured by the Beck Depression Inventory; bodily pain and impact were assessed with the 36-item Short Form Health Survey. Network and bootstrap permutation analyses were used to compare depressive symptoms endorsed by Low versus Moderate-to-Severe (Mod + Pain) groups. Multilayer networks estimated the effects of risk and protective factors. The overall sample was comprised of 78% men, mean age 40.7 years, with 53% opioid use disorder and 14% major depressive disorder. The Mod + Pain group was characterized by multiple types of pain, more persistent pain, more severe depressive symptoms and a higher rate of suicidal ideation. Global network connectivity did not differ between the two pain groups. Suicidal ideation was a network hub only in the Mod + Pain group, with high centrality and a direct association with exposure to lifetime trauma. Antidepressant medications had limited impact on suicidal ideation. Guilt and increased feelings of failure represented symptoms from two other communities of network nodes, and completed the shortest pathway from trauma exposure through suicidal ideation, to the non-prescribed opioid exposure node. Interventions targeting these risk factors and symptoms could affect the progression of depression among precariously housed patients.

    Abstract The approach to analysis of and interpretation of findings from the Beck Depression Inventory (BDI), a self-report questionnaire, depends on sample characteristics. To extend work using conventional BDI scoring, the BDI's suitability in assessing symptom severity in a homeless and precariously housed sample was examined using Rasch analysis. Participants (n=478) recruited from an impoverished neighbourhood in Vancouver, Canada, completed the BDI. Rasch analysis using the partial credit model was done, and the structural validity, unidimensionality, and reliability of the BDI were studied. A receiver operating characteristic curve determined a Rasch cut-off score consistent with clinical depression, and Rasch scores were correlated with raw scores. Good fit to the Rasch model was observed after rescoring all items and removing Item 19 (Weight Loss), and unidimensionality and reliability were satisfactory. Item 9 (Suicidal Wishes) represented the most severe symptom. Rasch-based scores detected clinical depression with moderate sensitivity and specificity, and were positively correlated with conventional scores. The BDI in a community-based sample of homeless and precariously housed adults satisfied Rasch model expectations in a 20-item format, and is suitable for assessing symptom severity. Future research on depression in similar samples may reveal more information on using specific symptoms to determine clinical significance.

    Abstract The Thoracic Society of Australia and New Zealand (TSANZ) and the Australian and New Zealand Society of Respiratory Science (ANZSRS) commissioned a joint position paper on pulmonary function testing during coronavirus disease 2019 (COVID-19) in July 2021. A working group was formed via an expression of interest to members of both organizations and commenced work in September 2021. A rapid review of the literature was undertaken, with a 'best evidence synthesis' approach taken to answer the research questions formed. This allowed the working group to accept findings of prior relevant reviews or societal document where appropriate. The advice provided is for providers of pulmonary function tests across all settings. The advice is intended to supplement local infection prevention and state, territory or national directives. The working group's key messages reflect a precautionary approach to protect the safety of both healthcare workers (HCWs) and patients in a rapidly changing environment. The decision on strategies employed may vary depending on local transmission and practice environment. The advice is likely to require review as evidence grows and the COVID-19 pandemic evolves. While this position statement was contextualized specifically to the COVID-19 pandemic, the working group strongly advocates that any changes to clinical/laboratory practice, made in the interest of optimizing the safety and well-being of HCWs and patients involved in pulmonary function testing, are carefully considered in light of their potential for ongoing use to reduce transmission of other droplet and/or aerosol borne diseases.
