2†Pathways to detection of non-infectious childhood uveitis in the UK: findings from the UNICORN cohort study.

INTRODUCTION: Prompt detection of childhood uveitis is key to minimising negative impact. From an internationally unique inception cohort, we report pathways to disease detection.UNICORNS is a national childhood non-infectious uveitis study with longitudinal collection of a standardised clinical dataset and patient reported outcomes. Descriptive analysis of baseline characteristics are reported.Amongst 150 recruited children (51% female, 31% non-white ethnicity) age at detection ranged from 2-18yrs (median 10). In 69%, uveitis was diagnosed following onset of symptoms: time from first symptoms to uveitis detection ranged from 0-739days (median 7days), with longer time to detection for those presenting initially to their general practitioner. Non symptomatic children were detected through JIA/other disease surveillance (16%), routine optometry review (5%) or child visual health screening (1%). Commonest underlying diagnoses at uveitis detection were JIA (17%), TINU (9%, higher than pre-pandemic reported UK disease frequency) and sarcoid (1%). 60% had no known systemic disease at uveitis detection. At disease detection, in at least one eye: 34% had structural complications (associated with greater time to detection - 17 days versus 4 days for uncomplicated presentation).The larger relative proportions of children with non-JIA uveitis reported here increase the importance of improving awareness of childhood uveitis amongst the wider clinical communities. There is scope for improvement of pathways to detection. Forthcoming analysis on the full cohort (251 recruited to date across 33 hospitals and 4 nations) will provide nationally representative data on management and the determinants of visual and broader developmental/well-being outcomes.

Management of patients in a combined thyroid eye clinic in secondary care.

The European Group on Graves' Orbitopathy (EUGOGO) recommends the use of specialised multidisciplinary clinics for the management of thyroid eye disease (TED). In the UK, many patients with TED are managed outside of specialised clinics. We describe the organisation of a combined TED clinic in a secondary care setting and present the result of a prospective audit of the patient characteristics and outcomes during the first four years of a combined TED clinic. Of a total of 132 patients referred to the TED clinic, 114 (86 %) had TED (90 females, median age 56 years; range 17-90 years). At presentation, 77 (67 %) were current or ex-smokers and 99 (87 %) were biochemically euthyroid. Median duration of eye symptoms was 12 months. Fifty-two percent, 45 and 3 had mild, moderate-to-severe and sight-threatening TED, respectively. Only 18 % of patients had a clinical activity score (CAS) of ≥3. Sixty-nine patients (61 %) required follow-up appointments in the TED clinic. In those who required follow-up, 43 % (n = 30) received either immunosuppressive or surgical treatment. CAS improved from first to final visit, with 29 % (n = 20) having a CAS of ≥3 at the first visit and 1 % (n = 1) at the final visit (p = 0.0001). There was also a decrease in prevalence of smoking and thyroid dysfunction at the final visit. A multidisciplinary specialised TED clinic offers an optimal setting for managing patients with TED; however, patients are often referred late to a specialist TED clinic.

The Cataract National Dataset electronic multicentre audit of 55,567 operations: antiplatelet and anticoagulant medications.

AIMS: This study aims to establish the prevalence of aspirin, dipyridamole, clopidogrel, and warfarin use in patients undergoing cataract surgery, and to compare local anaesthetic and intraoperative complication rates between users and non-users. METHODS: The Cataract National Dataset was remotely extracted and anonymised on 55,567 operations at 12 NHS Trusts using electronic patient records (EPRs) between 2001 and 2006. RESULTS: This report analyses 48,862 of the 55,567 operations from the eight centres, which routinely recorded a drug history. In all, 28.1% of the 48,862 patients were taking aspirin, 5.1% warfarin, 1.9% clopidogrel, and 1.0% dipyridamole. The recording of any complication of a sharp needle or subtenon's cannula local anaesthetic block was increased in patients taking clopidogrel, 8.0% (P<0.0001) or warfarin, 6.2% (P=0.0026) vs non-users, 4.3%, but no increase in potentially sight-threatening complications was identified. The incidence of subconjunctival haemorrhage was increased in patients taking clopidogrel, 4.4% (P<0.0001) or warfarin, 3.7% (P<0.0001) vs non-users, 1.7%. The recording of any operative complication was increased in those taking clopidogrel, 7.3% (P=0.0002) vs non-users, 4.4%, but the haemorrhagic operative complications of choroidal/suprachoroidal haemorrhage and hyphaema were not significantly increased. The non-haemorrhagic complication of posterior capsular rupture (PCR) was increased in those taking clopidogrel, 3.23% (P=0.0057) vs non-users, 1.77%. CONCLUSIONS: Clopidogrel or warfarin use was associated with a significant increase in minor complications of sharp needle and subtenon's cannula local anaesthesia but was not associated with a significant increase in potentially sight-threatening local anaesthetic or operative haemorrhagic complications.

[Clinical and paraclinical identification by various imaging technics of congenital anomalies of the inferior vena cava (apropos of 4 cases)]. / Identification clinique et paraclinique par les différentes techniques d'imagerie des anomalies congénitales de la veine cave inférieure (à propos de 4 cas).

Four cases of anomalies of the inferior vena cava (IVC) were studied by two noninvasive imaging techniques: real-time ultrasonography and computed tomography. These techniques were used alone in 1 case of left IVC to determine the diagnosis. The other 3 cases were studied initially by phlebography: left IVC with iliac phlebitis; double IVC, also with iliac phlebitis, and a special case in which it was not clear whether the diagnosis was agenesis of the IVC or postnatal caval thrombosis. The two patients with recent iliac vein thrombosis were treated by heparin, but the other two received no particular therapy. Concerning these 4 cases, the authors speak of the known complexity of embryogenesis of the IVC which accounts for the great diversity in its anomalies. Left and double IVC are among the most frequent anomalies along with periaortic venous rings and the ureter behind the IVC. These anomalies are most often asymptomatic, but an understanding of them is essential for correct interpretation of the results of different imaging techniques and for effective performance of surgical and medical acts concerning the IVC directly or indirectly. For diagnosis of IVC anomalies, iliac venacavography, when not performed initially, can in certain cases be replaced by routine noninvasive imaging techniques, to which may now be added magnetic resonance imaging.
