PURPOSE The Immulite® thyroid stimulating immunoglobulin (TSI) immunoassay is a relatively new commercial assay that has shown good diagnostic accuracy in Graves' hyperthyroidism (GH). However, its clinical utility in thyroid-associated orbitopathy (TAO) is less clear. The purpose of this study was to assess the diagnostic accuracy of the Immulite® TSI immunoassay for TAO and investigate the associations between TSI and other clinical measures. METHODS One hundred and forty patients that had been diagnosed with GH within the previous 12 months were recruited. Identification and grading of TAO were performed at enrolment and serum samples were analysed using the Immulite® TSI immunoassay. RESULTS Of the 140 participants recruited, 75 (53.6%) had TAO. Age, sex and time since GH diagnosis were similar between those with and without TAO (p ≥ 0.300). TSI level tended to decrease with increasing time from GH diagnosis (Spearman's ρ - 0.28, 95% CI - 0.43, - 0.12). TSI levels were higher among those with than those without TAO (median 4.0 vs. 2.7 IU/L, respectively, p = 0.037). There was no correlation between TSI level and inflammatory index score (ρ = 0.14, 95% CI - 0.03, 0.30) or clinical severity (p = 0.527) among those with TAO. TSI level showed poor diagnostic accuracy for TAO (area under the receiver operating characteristic curve 0.60, 95% CI 0.51, 0.70). CONCLUSIONS Although Immulite® TSI level was higher in the presence of TAO, it showed poor diagnostic accuracy and no correlation with clinical markers of TAO severity or activity.

Subperiosteal orbital haematoma (SOH) is an uncommon condition that involves bleeding within the potential space between the periosteum and orbital bone. This typically occurs within the superior orbit. If the SOH is large enough it can compress orbital structures and be sight threatening. Therefore, it is important for the clinician to recognize the potential causes for this phenomenon which will help guide the diagnosis. Herein we describe a unique case of unilateral SOH in a 47-year-old male following otherwise uncomplicated general anaesthesia. This occurred 6 weeks after a motorbike accident in which there was no facial/ocular injury. This case report identifies for the first time the potential for a late-onset SOH in the setting of a stressor event. It also highlights the potential for this condition to occur following general anaesthesia in a supine patient having a non-cardiac procedure, previously recognized as a potential stressor.

Objectives: To compare the characteristics and outcomes of patients presenting to hospital with alcohol-induced and gallstone-induced acute pancreatitis. Methods: Retrospective study of all patients with alcohol-induced or gallstone-induced pancreatitis during the period 1 June 2012 to 31 May 2016. The primary outcome measure was hospital mortality. Secondary outcome measures included hospital length of stay, requirements for intensive care unit admission, intensive care unit mortality, mechanical ventilation, renal replacement therapy, requirement of inotropes and total parenteral nutrition. Results: A total of 642 consecutive patients (49% alcohol; 51% gallstone) were included. No statistically significant differences were found between alcohol-induced and gallstone-induced acute pancreatitis with respect to hospital mortality, requirement for intensive care unit admission, intensive care unit mortality and requirement for mechanical ventilation, renal replacement therapy, inotropes or total parenteral nutrition. There was significant difference in hospital length of stay (3.07 versus 4.84; p Conclusion: Hospital mortality did not differ between patients with alcohol-induced and gallstone-induced acute pancreatitis. The duration of hospital stay was longer with gallstone-induced pancreatitis. Bedside Index of Severity in Acute Pancreatitis score and admission haematocrit were independently associated with hospital length of stay.

Objective: To describe the characteristics of patients presenting to an Emergency Department (ED) following overdoses; to identify risk factors for intensive care unit (ICU) admission among these patients; and to identify the rate of mortality and repeat overdose presentations over four years. Methods: Adult patients presenting to ED following drug overdose during 2014 were included. Data were collected from medical notes and hospital databases. Results: During the study period, 654 patients presented to ED 800 times following overdose. Seventy-eight (9.8%) resulted in ICU admission, and 59 (7.4%) required intubation; 57.2% had no history of overdose presentations, and 72.9% involved patients with known psychiatric illness. Overdose of atypical antipsychotics (AAP), age and history of prior overdose independently predicted ICU admission. A third of patients ( n = 196, 30%) had subsequent presentations to ED following overdose, in the four years from their index presentation, with an all-cause four-year mortality of 3.4% ( n = 22). Conclusion: A history of overdose, use of AAP and older age were risk factors for ICU admission following ED presentations. Over a third of patients had repeat overdose presentation in the four-year follow-up with a mortality of 3.4%.

Modern advancements in surgical technique and intraocular implants have reduced the size of the incision required for cataract surgery. However, despite their small size, these wounds may constitute areas of weakness in the globe many years after healing. The inherent weakness from the healed incision may be the site of globe rupture following sudden, severe increases in intraocular pressure from blunt trauma to the eye or face. This case report discusses a 92-year-old woman who presented with a macrohyphema and globe rupture of the left eye following blunt facial trauma. Surgical globe repair was performed which revealed total traumatic aniridia and a posteriorly tilted intraocular lens. The patient progressed without complications and achieved a final visual acuity of 6/18 in the affected eye. This case highlights the lasting structural weakness following cataract surgery which may persist for years and leave the globe susceptible to rupture.
