one percent (246) said they do not stop other anticoagulants (including aspirin, clopidogrel, heparins and novel oral antiocoagulants) prior to surgery. Seventy-eight percent (236) of consultants cancelled based on blood glucose, with 40% (121) stating above 25 mmol/L, and 32% (97) above 15 mmol/L. Of all the criteria, heart rate gave the most variable response, with only 40% (123) considering it as a reason for cancellation. There was a huge variety in the upper limit, and symptomatic tachycardia understandably was the most important reason (14.8%, 45) rather than the rate. Consultants across the UK show some consensus on when to cancel patients in relation to blood pressure, blood glucose, INR level and most do not routinely stop other forms of anticoagulation. However, there remains some variability in practice, which is understandable given the lack of specific guidance at present. Studies looking at the influence that these factors may have on cataract surgery are currently limited. A national audit looking at these parameters in relation to complications may be warranted. Our survey highlights a need for more exploration into the immediate pre-operative management of patients.
Background The availability and reduced cost of genotyping has improved gene susceptibility testing and our scientific understanding of disease pathophysiology. Whilst several personalised translational models exist within medical frameworks, genetic-based surgical therapy is a translational application not widely used in surgical specialties. Method We present a clinical series of five patients with genetically confirmed bestrophinopathy and malignant glaucoma (MG). Patients were followed up for 12 months or more after receiving surgical intervention to manage refractory intraocular pressure (IOP) resistant to medical treatment. Findings Patients with BEST1 gene mutations are at higher risk of MG after filtration surgery. A multi-disciplinary approach after four patients experienced poor outcomes concluded that traditional first-line glaucoma surgery was not sufficient to prevent visual loss. A fifth patient presenting with the identified at-risk phenotype underwent primary pars plana vitrectomy, with pars plana Baerveldt tube insertion, successfully preventing MG and had no glaucoma progression after 5 years. Interpretation We provide proof-of-principle that genetic analysis can be used to inform the selection of surgical therapy to improve outcomes. In this case, a refinement of current surgical methods to avoid MG. Although challenges remain, personalised surgery has the potential to improve clinical outcomes beyond the scope of current surgical practice.
Very old patients with nAMD benefited from aflibercept, but not to the same degree as the younger patients. The study showed that, on an average, the very elderly patients were able to adhere to the intensive anti-VEGF treatment regimens.
Background: Antibiotic prophylaxis is crucial in head and neck surgery to prevent infection from clean contaminated wounds. Scottish Intercollegiate Guidelines Network (SIGN) guidance, the gold standard of practice, recommends that administration of broad spectrum antibiotics is discontinued after 24 hours post-operation. A three-audit cycle quality improvement project was conducted to assess clinical practice against SIGN guidance at a large London teaching hospital. Methods: Three change initiatives were implemented to improve antibiotic stewardship. First, an update of Trust guidelines with an associated poster campaign to educate staff and improve awareness. Second, introduction of a specific ‘prophylactic antibiotics in head and neck surgery’ bundle on the electronic hospital-wide prescribing system. Third, an update to an antibiotic prescribing guide (Microguide). Results: Over a 3-year study period the number of patients receiving antibiotics beyond 24 hours declined significantly (88% in 2015, 76% in 2016, 25% in 2018), demonstrating improved compliance with SIGN guidelines overall. Despite this, staff documentation of indications for extended antibiotic use remains suboptimal (58% in 2016 and 44% in 2018) as does the number of specimens sent for microbiological analysis (52% in 2016 and 0% in 2018). Conclusions: Appropriate prophylactic antibiotic prescribing can improve morbidity and mortality rates in head and neck cancer patients. Three change initiatives have been demonstrated which can help to improve prescribing compliance in line with SIGN guidance. Ongoing auditing is required to maintain the longevity of improvements made and encourage staff documentation of indications for extended antibiotic use and microbiology specimen analysis.
X-Linked Retinoschisis (XLRS) is a common genetically determined form of macular degeneration affecting young males. XLRS is due to mutations in the RS1 gene located on chromosome Xp22 which codes for retinoschisin and is estimated to affect between 1:5000 to 1:20000 individuals worldwide. We report a case of refractory angle-closure glaucoma in a thirty-nine-year-old Caucasian man with atypical XLRS. The patient presented with a two-day history of left eye pain, acutely reduced vision and a nine-month history of hemicranial pain. Examination identified left intraocular pressure (IOP) of 52mmHg. Gonioscopy confirmed complete angle closure. Following failure of medical management and persistently raised left IOP (43-46mmHg), the patient underwent left phacoemulsification and intraocular lens insertion without complication. After surgery, his IOP reduced to 10-14mmHg on all follow up examinations without the need for glaucoma drops. His iridocorneal angle remained open and vision improved to 20/100. Our case demonstrates the additional role of lens surgery in the treatment of secondary angle-closure glaucoma in the presence of an inherited retinal dystrophy. All patients with inherited retinopathy presenting with a headache or eye pain should undergo gonioscopic examination to exclude angle-closure glaucoma.
