We believe these medium to long-term results with first-generation endoprostheses are encouraging and justify the continued use of endoprostheses for reconstruction following the excision of a bone tumor.
Ten patients underwent endoprosthetic replacement of the distal humerus for bone tumours over a period of 30 years. There were eight primary and two secondary tumours in four men and six women with a mean age of 47.5 years (15 to 76). The mean follow-up was eight years (9 months to 31 years). Four patients required further surgery, three having revision for aseptic loosening; two of these and one other later needing a rebushing. There were no cases of postoperative nerve palsy, infection, local recurrence or mechanical failure of the implant. Four patients died from their disease, all with the prosthesis functioning satisfactorily. At follow-up the mean flexion deformity of the elbow was 15 degrees (0 to 35) and the mean range of lexion was 115 degrees (110 to 135). The functional results showed a mean Toronto extremity salvage score of 73% of normal. Endoprosthetic replacement of the distal humerus and elbow is a satisfactory method of treating these rare tumours.
To examine the efficacy of intravitreal bevacizumab for pain relief in eyes with refractory neovascular glaucoma.Methods: In this prospective case series, 52 eyes with neovascular glaucoma were administered intravitreal bevacizumab, 1.25 mg, and monitored for 6 months. The primary outcome measure was change in subjective pain score. Intraocular pressure and iris neovascularization were evaluated at each visit. Surgical intervention for control of intraocular pressure was performed according to clinical need. Results: Forty-two patients (44 eyes) completed the 6-month follow-up. Subjective pain score was reduced significantly 1 week after intravitreal bevacizumab injection and lasted throughout the follow-up period (median [interquartile range]: baseline, 3 [0-6]; week 1, 1 [0-3]; month 1, 0 [0-1]; month 3, 0 [0-1]; and month 6, 0 [0-0]; Kruskal-Wallis 2 31.03; P Ͻ.001). A rapid, yet relatively transient, reduction in iris neovascularization was also noted (iris neovascularization grade at baseline, 4.0 [3-4]; week 1, 2.5 [1-4]; month 1, 2.0 [1-4]; month 3, 3.0 [2-4]; and month 6, 3.0 [2-4], 2 23.33;PϽ.001). Four eyes (8%) required more than 1 injection to facilitate further intraocular surgery.Conclusions: Intravitreal bevacizumab is a useful adjunct in the management of refractory neovascular glaucoma, producing rapid relief of pain. However, we found no evidence to suggest that intravitreal bevacizumab lowers intraocular pressure in eyes with angle closure; conventional medical, laser, and surgical treatment are still needed in these eyes.
Background/aimsTo evaluate the efficacy and safety of the PreserFlo MicroShunt glaucoma device in a multicentre cohort study.MethodsAll consecutive patients who received the microshunt with mitomycin-C (MMC) 0.4 mg/mL from May 2019 to September 2020 in three UK tertiary centres. Primary outcome at 1 year was a complete success, with failure defined as intraocular pressure (IOP) >21 mmHg or <20% reduction, IOP≤5 mmHg with any decreased vision on two consecutive visits, reoperation or loss of light perception vision. Secondary outcomes were IOP, best-corrected visual acuity, medications, complications, interventions and reoperations. We also performed subgroup analyses for severe glaucoma and assessed risk factors for failure.Results104 eyes had 1-year follow-up. Complete and qualified success at 1 year were achieved in 51.9% (N=54) and 16.4% (N=17), respectively, and failure occurred in 31.7% (N=33). There was a significant reduction in IOP (mmHg) from preoperatively (23.4±0.8, N=104) to 12 months (14.7±0.6, N=104) (p<0.0001). Antiglaucoma medications also decreased from preoperatively (3.4±0.1, N=104) to 12 months (0.7±0.1, N=104) (p<0.0001). Multivariate analyses showed an association between higher mean deviation and failure (HR 1.055, 95% CI 1.0075 to 1.11, p=0.0227). Complications were hypotony (19.2%; N=20), choroidal detachments (10.6%; N=11), hyphaema (5.8%; N=6) and bleb leak (5.8%; N=6). Needling and 5-fluorouracil injections were performed in 12.5% (N=13) and 33.7% (N=35), respectively, and 11.5% (N=12) required revision surgery.ConclusionThe PreserFlo MicroShunt with MMC 0.4 mg/mL showed an overall success rate of 68.3% at 1 year, and led to significant IOP and medication reduction with a low rate of adverse effects.
case of pencil-gore granuloma occurring 45 years after the initial injury is described. The clinical and radiological presentation was suggestive of a soft-tissue sarcoma. The diagnosis was confirmed by biopsy, which also revealed foreign body fragments which, on spectometric analysis, had high concentrations of carbon and aluminium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
