This study investigated the impact Lean Six Sigma, a service improvement methodology originally from manufacturing, reducing times increasing capacity publicly-funded, tertiary referral ophthalmology clinic. Methods compared results two five-months audits operational...
Although measures to control covid-19 have been associated with some positive environmental effects, including decreases in global emissions of carbon dioxide, 1 the pandemic has exacerbated plastic pollution through high use personal protective equipment (PPE).Single items include surgical masks, gloves, and non-reusable gowns.
Abstract Background/aims Despite evidence that preferential use of balanced/buffered fluids may improve outcomes compared with chloride-rich 0.9% saline, saline remains the most commonly used fluid for children septic shock. We aim to determine if resuscitation as part usual care will outcomes, in through reduced kidney injury and without an increase adverse effects, Methods The Pragmatic Pediatric Trial Balanced versus Normal Saline Fluid Sepsis (PRoMPT BOLUS) study is international,...
To examine changing patterns of ophthalmic presentations to emergency departments (EDs) during the lockdowns associated with first wave COVID-19 pandemic in Australia and two months immediately following lockdown relaxation.This was a retrospective audit triage coding ICD-10-AM for all patient four Australian EDs from March 29 May 31 2019 2020 (the period corresponding 2019), June 1 July post-lockdown 2019). Number triaged per day number seven common and/or time-sensitive, vision threatening...
Abstract Background There is a need for effective health service solutions to provide greater structure and support implementing evidence‐based practice in back pain care. Patient involvement developing these crucial increase relevance, acceptability uptake. Objectives To determine patients' perceived needs barriers best‐practice care, potential better address care needs.

Abstract Background To identify and classify materials in the vitreous observed during phacoemulsification cataract surgery (phaco). Design Prospective, consecutive, observational case series at one ophthalmic day Sydney, Australia. Participants A total of 767 consecutive phaco cases. Cases were excluded if there was posterior capsule rupture or loss intraoperatively. Methods For each patient, age, gender, baseline corrected distance visual acuity, presence pseudoexfoliation, nuclear...
Objective: To examine patterns of airborne allergen (aeroallergen) sensitisation in the Greater Sydney area (Sydney), and their relationships with climate, coastal proximity environment (urban v regional). Design, setting, participants: Retrospective cross-sectional study patients who underwent aeroallergen skin prick testing at three allergy clinics, January 2001 – October 2014. Main outcome measurements: Proportions sensitised to specific types; between climate geography. Results: Of 1421...
Neurological complications have been reported to occur in 3% of hemiarthroplasties, 0.1% 4% anatomic total shoulder arthroplasties, and 2% reverse arthroplasties. The brachial plexus is most commonly involved. Observations cadaver studies suggested that the likely etiology these neuropathies stretch secondary patient arm positioning. Although majority injuries resolve spontaneously, permanent debilitating do occur, but rarely. Cadaver intraoperative nerve monitoring identified abduction >90...
<b><i>Background:</i></b> Currently, transvitreal fine-needle aspiration biopsy is the most widely used tissue technique in cases of suspected intraocular lymphoma due to its relative simplicity and low trauma. The small sample produced, however, may be inadequate for diagnostic prognostic analyses mechanical artefacts, insufficient material, or sampling errors. Small case series have demonstrated choroidal via vitrectomy safe effective. With smaller-gauge...
The practice of cement augmentation in pedicle screw fixation is well established. However, there a lack consensus regarding the optimal design or type. This remains clinically important question given incidence augmentation-associated complications. While fenestrated screws have become widely used clinical practice, relationship between fenestration placement along axis and plume geometry pullout strength yet to be clarified. study was designed evaluate mechanical geometric properties...
To report a case of rapid "epiretinal membrane" ("ERM") development following intravitreal bevacizumab for juvenile Coats' disease.A 7-year old boy was followed four years with asymptomatic stage 2 disease in his left eye. At age 11, he developed symptomatic cystoid macular edema. Argon laser photocoagulation to the leaking aneurysms failed improve vision, which had symptomatically declined 20/30. Four-months after laser, single injection given. Rapid an "ERM" noticed on first post-injection...
To assess whether lumbar pedicle screw placement with a minimally invasive surgical (MIS) vs. open technique imparts different biomechanical parameters and thus may affect failure rates.Human cadaveric disarticulated vertebrae 1-5 were stabilised in cement. Pedicle screws inserted either via the 'MIS' or 'open' technique, based on previously described anatomical landmarks. Each vertebra had one screw. Specimens tested an Instron mechanical testing machine, positioned to allow for of direct...
Detachment of a hydrodissection cannula during phacoemulsification procedure appeared to produce no adverse sequelae surgery. Day 1 postoperatively, two nonpenetrating hemorrhagic retinal lesions were identified; there was evidence posterior capsular perforation. 6 the pupil temporally peaked by fine vitreous strand running main-port incision in superotemporal cornea. This divided with Nd:YAG laser, and argon laser applied encircle lesions. Postoperative uncorrected visual acuity remained...
Compression of anterior visual pathway (AVP) structures by intracranial arteries is observed not infrequently on neuroimaging. Whether or such compression results in damage to these structures, however, remains unclear. This information important define as AVP may be a causative factor patients with otherwise unexplained dysfunction. In single centre, 37 evidence artery demonstrated magnetic resonance imaging were identified retrospective review case records over the period 2011-2017....
Nasal dilator strips are thought to widen and stiffen the anterior nasal cavity, thus improve symptoms of obstruction. It is postulated that anthropomorphic differences in external proportions between races may influence effectiveness such strips.Caucasian Asian subjects were compared. peak inspiratory flow, airway resistance, minimum cross-sectional area visual analogue scale measurements obstruction recorded at baseline following application two different strips.Nine Caucasian six...
A 67-year-old Caucasian male presented with severe contraction of socket lining 8 years after enucleation, dermis fat graft and successful ocular prosthesis fitting. Following two failed attempts at using amniotic membrane grafts to reform the lining, a total reconstruction was attempted novel nasal turbinate mucosal technique. This performed in staged fashion lower fornix followed by upper 3 months later. The patient stable 12 review, satisfactory cosmetic outcome. Nasal mucosa used as it...
BackgroundThe COVID-19 pandemic has caused unprecedented global demand for personal protective equipment (PPE). A paucity of data on PPE burn rate (PPE consumption over time) in situations exacerbated these issues as there was little historic research to indicate volumes required care surges infective patients and thus plan procurement requirements.MethodsTo better understand requirements suspected or confirmed our Australian quaternary referral hospital, the number staff-to-patient...
