Abstract Purpose—To Highlight The Efficacy Of Primary AGV Implantation In Angle Recession Glaucoma Following Blunt Ocular Trauma In Indian Eyes.Design- A retrospective analytical studyMaterials & Methods— This study included 52 patients of angle recession glaucoma, who presented between Mar 2006 to Feb 2016, out of which 38 patients had undergone primary AGV implantation while the rest were managed with topical anti-glaucoma medications. Preoperative data included age, sex, type & mode of injury, duration of injury, assessment of BCVA and IOP. Extent of angle recession was observed by gonioscopy. The intraocular pressure, visual acuity and number of anti-glaucoma medications were measured postoperatively. The success of this technique was analyzed by using a Kaplan-Meier cumulative survival curve.Results—Following AGV implantation the mean IOP was significantly reduced to 8.7±2.2 at 1st day, 10.1±2.2 at 7th day, 14.2±3.4 at 3rd month, 15.6±3.7 at 1 year and 15.6±3.6 at 3rd year follow-up showing statistically significant values (p<0.001) at each visit. The IOP was successfully controlled at last follow up without topical treatment. Mean BCVA at 3 year post AGV was 0.41±1.5 (logMAR) which was statistically significant (p<0.001).The success rate by Kaplan- Meier survival curve analysis was 90% at the mean follow up duration of 29.47±3.39 months. Overall surgical complications were noted in the form of prolonged hypotony, hyphema in 7 patients (13.5%).Conclusions—In medically uncontrolled post-traumatic angle recession glaucoma Primary AGV Implantation is a safe and effective surgical procedure with lesser complication rates providing long term IOP control in younger population .

Abstract Precis: Phacoemulsification combined with MicroPulse transscleral cyclophotocoagulation appears to provide significantly greater long-term IOP reduction than phacoemulsification combined with endoscopic cyclophotocoagulation without compromising safety.Purpose: To compare the effectiveness and safety of phacoemulsification combined with endoscopic cyclophotocoagulation (phaco/ECP), phacoemulsification combined with MicroPulse transscleral cyclophotocoagulation (phaco/MP-TSCPC), and phacoemulsification alone (phaco) in the treatment of coexisting cataract and glaucoma. Methods: Retrospective cohort study of consecutive cases at Massachusetts Eye & Ear. The main outcome measures were the cumulative probabilities of failure between the phaco/ECP group, phaco/MP-TSCPC group, and the phaco alone group with failure defined as reaching NLP vision at any point postoperatively or the inability to maintain ≥20% IOP reduction from baseline with IOP between 5-18 mmHg. Additional outcome measures included changes in average IOP, number of glaucoma medications, and complication rates. Results: 64 eyes from 64 patients (25 phaco/ ECP, 20 phaco/ MPTSCPC, 19 phaco alone) were included in this study. The groups did not differ in age (mean 71.04 ± 6.7 years) or length of follow-up time. Primary open-angle glaucoma was the most common type of glaucoma in the phaco alone (42%) and phaco/ECP (48%) groups while mixed-mechanism glaucoma was the most common type in the phaco/MP-TSCPC group (40%). The mean IOP reductions at 1 year were 3.07 ± 5.3 mmHg from a baseline of 15.78 ± 4.7 in the phaco/ECP group, 6.0 ± 4.3 mmHg from a baseline of 18.37 ± 4.6 in the phaco/MP-TSCPC group and 1.0 ± 1.6 from a baseline of 14.30 ± 4.2 mmHg in the phaco alone group. Surgical failure was less likely in eyes in the phaco/MP-TSCPC and phaco/ECP groups compared to phaco alone based on the Kaplan-Meier survival criteria, with failure defined as the inability to maintain an IOP reduction of 20% or more with IOP between 5-18 mm Hg long term. There were no differences in complications among the three groups. Conclusions: Phaco/MP-TSCPC appears to provide for greater long-term IOP control than phaco alone and phaco/ECP. All three procedures had similar safety profiles.

Background/AimsTo assess the role of microperimetric retinal sensitivity (MPRS) and inner choroid flow deficits (IC FD) in predicting the development of incomplete retinal pigment epithelial and outer retinal atrophy (iRORA) in intermediate AMD (i-AMD).MethodsThirty eyes with i-AMD evaluated at the Doheny-UCLA Eye Centres were enrolled in this prospective IRB-approved study. Subjects underwent several diagnostic tests: (a) 6×6 mm swept-source optical coherence tomography angiography (SS-OCTA) with the IC slab used to quantify the FDs, (b) 20°×20° spectral-domain optical coherence tomography (SD-OCT) to monitor progression to iRORA and (c) scotopic MPRS within an area of 18° centred on the fovea. All subjects were followed-up for 24 months. The baseline IC FD and MPRS were correlated with the development of iRORA. At 24-month follow-up, the stage of AMD was re-assessed and the eyes were divided into two sub-groups based on the development of iRORA.ResultsTwenty-eight eyes completed the 2-year follow-up. At baseline, the mean MPRS was 13.40±4.66 dB and the mean IC FD was 27.55±8.67%. The morpho-functional regression showed a significant correlation between baseline MPRS and IC FD and the development of iRORA within 24 months (R2=0.744, p<0.05). A Kaplan–Meier survival curve was fit to determine the cumulative incidence of iRORA over the 24 months.ConclusionsA lower MPRS and greater IC FD at baseline were predictors of progression to iRORA in eyes with i-AMD. These parameters may be useful biomarkers for risk stratification and prognostication.

The IVORY® prosthesis is a total trapeziometacarpal joint prosthesis used for the treatment of symptomatic trapeziometacarpal osteoarthritis. The aim of this prospective study was to evaluate its long-term outcomes with a minimum follow-up of 10 years. From 2004 to 2007, 110 trapeziometacarpal prostheses (95 patients) were implanted. The implant survival curve was constructed using the Kaplan–Meier method. Five patients were lost from follow-up and two died. Six prosthesis (5.5%) were removed after dislocation or fracture of the trapezium. The survival rate of the prosthesis was 95%. After 10 years, the mean visual analogue pain score was 0.24/10 and the key-pinch force was similar to the other hand. Dislocations occurred for eight implants (7.3%). No radiological loosening was noted. In conclusion, the long-term results with the IVORY® prosthesis are very satisfactory in terms of pain relief, function and survival. Level of evidence: II

Background: Pelvic organ prolapse is a common condition, affecting about 50% of women with children. The aim of our study was to evaluate results and complication rates in a consecutive series of female patients undergoing robot-assisted laparoscopic hysterosacropexy (RALHSP). Materials and Methods: We performed a medical record review of female patients with uterine prolapse who had consecutively undergone RALHSP from February 2010 to 2013 at our department. Results: Fifteen patients were included in the analysis. All patients had uterine prolapse stage ≥II and urodynamic stress urinary incontinence. The mean age was 58.26 years. According to the Clavien-Dindo system, 4 out of 15 patients (26.6%) had grade 1 early complications and 1 patient had a grade 2 complication. At a median follow-up of 36 months, there was a significant prolapse relapse rate of 20% (3/15). Conclusion: In our hands RALHSP is easy to perform, with satisfying mid-term outcomes and a low complication rate.

Background: The rate of elbow medial ulnar collateral ligament (MUCL) injury and surgery continues to rise steadily. While authors have failed to reach a consensus on the optimal graft or anchor configuration for MUCL reconstruction, the vast majority of the literature is focused on the young, elite athlete population utilizing autograft. These studies may not be as applicable for the “weekend warrior” type of patient or for young kids playing on high school leagues or recreationally without the intent or aspiration to participate at an elite level. Purpose: To investigate the clinical outcomes and complication rates of MUCL reconstruction utilizing only allograft sources in nonelite athletes. Study Design: Case series; Level of evidence, 4. Methods: Patient records were retrospectively analyzed for individuals who underwent allograft MUCL reconstruction at a single institution between 2000 and 2016. A total of 25 patients met inclusion criteria as laborers or nonelite (not collegiate or professional) athletes with a minimum of 2 years of postoperative follow-up. A review of the medical records for the included patients was performed to determine survivorship free of reoperation, complications, and clinical outcomes with use of the Summary Outcome Determination (SOD) and Timmerman-Andrews scores. Statistical analysis included a Wilcoxon rank-sum test to compare continuous variables between groups with an alpha level set at .05 for significance. Subgroup analysis included comparing outcome scores based on the allograft type used. Results: Twenty-five patients met all inclusion and exclusion criteria. The mean time to follow-up was 91 months (range, 25-195 months), and the mean age at the time of surgery was 25 years (range, 12-65 years). There were no revision operations for recurrent instability. The mean SOD score was 9 (range, 5-10) at the most recent follow-up, and the Timmerman-Andrews scores averaged 97 (range, 80-100). Three patients underwent subsequent surgical procedures for ulnar neuropathy (n = 2) and contracture (n = 1), and 1 patient underwent surgical intervention for combined ulnar neuropathy and contracture. Conclusion: Allograft MUCL reconstruction in nonelite athletes demonstrates comparable functional scores with many previously reported autograft outcomes in elite athletes. These results may be informative for elbow surgeons who wish to avoid autograft morbidity in common laborers and nonelite athletes with MUCL incompetency.

Background/aimsTo determine the mortality within 20 years of diagnosis of chronic open-angle glaucoma (COAG) and visual acuity and visual field progression of a cohort followed for 20 years.MethodsTwenty years following the diagnosis of COAG in 68 of 436 (16%) patients seen in a glaucoma case-finding clinic, visual and mortality outcomes were audited from medical records. Causes of death were obtained from general practitioner records and death certificates. Probability of death was calculated using a Kaplan-Meier survival curve. The visual field of each eye of survivors was graded using a nine-stage severity scale. Visual outcome was analysed at the 20-year follow-up visit.ResultsFrom 68, 14 (21%) were lost to follow-up. In the remaining 54, 20 (37%) were alive 20 years after diagnosis. Of 63% who died, mean age of death was 84 years, most commonly due to vascular disease. Mean age at presentation of those who died was 73.7 years versus 63.2 years for survivors (P=0.001). The median time to death was 16 years. On visual field analysis, nearly half (48.9%) of eyes did not deteriorate, but 28.3% eyes deteriorated by more than two stages. Those who died had worse final visual acuity than survivors (P<0.001). Three who died were registered severely visually impaired mainly from macular disease, but no survivors were registered (P<0.001).ConclusionIn this cohort, approximately two-thirds of patients with glaucoma died within 20 years of diagnosis. In most older patients with glaucoma, the overall goal of preventing visual handicap and blindness is achievable 20 years after diagnosis.

Objective: To investigate the incidence and the prognosis of cognitive impairment (CI) and to find out the risk factors associated with the outcome in maintenance haemodialysis (MHD) patients. Methods: Enrolled the patients who met the criteria as below: MHD (≥3 months) patients before July 2014, ≥18 years old and could carry on the cognitive function test (Montreal Cognitive Assessment [MoCA]). All enrolled patients were divided into 2 groups: CI group (MoCA < 26) and non-CI group (MoCA ≥26). All patients were followed up for 36 months. The incidence, demography data, medical history, haemodialysis data, laboratory examination and prognosis of CI in haemodialysis patients were prospectively compared and analyzed. Multivariate logistic regression analysis was used to investigate the risk factors of CI. Kaplan-Meier survival curve was used for survival analysis. Results: In the present study, 219 patients were enrolled. The ratio of male to female was 1.46: 1. Age was 60.07 ± 12.44 and dialysis vintage was 100.79 ± 70.23 months. One hundred thirteen patients’ MoCA scores were lower than 26 were divided into CI group. Education status (OR 3.428), post-dialysis diastolic pressure (OR 2.234) and spKt/V (OR 1.982) were independent risk factors for CI in MHD patients. During the follow-up period, 15 patients died (13.2%) in the CI group and 5 died (4.72%) in the non-CI group (p < 0.05). The Kaplan-Meier survival curve analysis showed that the survival rate of patients with CI was lower than that of non-CI group in MHD patients during 3 years follow-up (p = 0.046). Conclusion: CI is one of the most common complications in MHD patients. The mortality is high in patients who had CI. Education status, post-dialysis diastolic pressure and spKt/V are independent risk factors for CI in MHD patients.

Introduction: Masquerading bundle branch block (MBBB) is a rare cardiac conduction anomaly characterized in the Electrocardiogram (EKG) by Right Bundle Branch Block in the precordial leads and Left Bundle Branch Block in frontal leads. The available evidence indicates that it carries poor prognosis and that it is often underdiagnosed. We studied epidemiological peculiarities, electrocardiographic features and prognosis of this rare kind of ventricular conduction delay. Methods: In a review of over 600,000 EKGs from the database of Tele-Electrocardiography department of Dante Pazzanese Institute of Cardiology during the last seven years, we found twenty-five cases of MBBB. Diagnostic criteria were presence of QRS ≥ 0.12 s, dominant positive waves in V1, left axis deviation and absent or minimal S wave in DI and aVL. Epidemiological data was collected for each EKG and the follow-up of patient′s health status was assessed by telephone contact. Kaplan-Meier survival curves were based on the following endpoints: mortality, pacemaker implantation and the composite of both. Results: We identified twenty-five cases (21 males and 4 females) of MBBB. The average age was 69 (±14) years. Sinus rhythm was present in 17 patients (68%), atrial fibrillation in 7 (28%) and atrial flutter in one (4%). Average heart rate, PR interval, QRS length, QTc and QRS axis were, respectively: 70 (±17) bpm, 205 (±50) ms, 159 (±24) ms, 463 (±37) ms and -76° (±6) degrees. Follow-up data was successfully obtained from 15 patients: 4 (26.6%) had a pacemaker implanted, 7 (46.6%) died and 9 had combined endpoints (60%). According to the Kaplan-Meier survival curve, at 48 months, the estimated ratios of death, pacemaker implantation or combined endpoints were 41.4%, 38.9% and 80.2%, respectively. Conclusions: MBBB represents a high-risk condition and, although rare, this EKG pattern should be taken into consideration due to the poor prognosis associated with its presence.

Purpose: To compare the outcomes of iliac branch devices (IBD) used in combination with standard endovascular aneurysm repair (EVAR) vs with fenestrated/branched EVAR (f/bEVAR) to treat complex aortoiliac aneurysms. Materials and Methods: The pELVIS Registry database containing the outcomes of IBD use at 8 European centers was interrogated to identify all IBD procedures that were combined with either standard EVAR or f/bEVAR. Among 669 patients extracted from the database, 629 (mean age 72.1±8.8 years; 597 men) had received an IBD combined with standard EVAR vs 40 (mean age 71.1±8.0 years; 40 men) who underwent f/bEVAR with an IBD. The mean aortic aneurysm diameters were 46.4±13.3 mm in the f/bEVAR patients vs 45.0±15.5 mm in the standard EVAR cases. The groups were similar in terms of baseline clinical characteristics and aneurysm morphology. The Kaplan-Meier method was used to compare patient survival, IBD occlusion, type III endoleak, and aneurysm-related reinterventions in follow-up. The estimates are presented with the 95% confidence interval (CI). Results: Technical success was 100% in the f/bEVAR+IBD group and 99% in the EVAR+IBD group (p=0.85). The 30-day mortality was 0% vs 0.5%, respectively (p=0.66), while the 30-day reintervention rates were 7.5% vs 4.1% (p=0.31). The mean follow-up was 32.1±21.3 months for f/bEVAR+IBD patients (n=30) and 35.5±26.8 months for EVAR+IBD patients (n=571; p=0.41). The 12-month survival estimates were 93.4% (95% CI 93.2% to 93.6%) in the EVAR+IBD group vs 93.6% (95% CI 93.3% to 93.9%) for the f/bEVAR+IBD group (p=0.93). There were no occlusions or type III endoleaks in the f/bEVAR+IBD group at 12 months, while the estimates for freedom from occlusion and from type III endoleak in the EVAR+IBD group were 97% (95% CI 96.8% to 97.2%) and 98.5% (95% CI 98.4% to 98.6%), respectively. The 12-month estimates for freedom for aneurysm-related reintervention were 93% (95% CI 92.7% to 93.3%) in the EVAR+IBD group vs 86.4% (95% CI 85.9% to 86.9%) in the f/bEVAR+IBD patients (p=0.046). Conclusion: Treatment of complex aortoiliac disease with f/bEVAR+IBD can achieve equally good early and 1-year outcomes compared to treatment with IBDs and standard bifurcated stent-grafts, except for a somewhat higher reintervention rate in f/bEVAR patients.

Aims This study aimed to evaluate the incidence and prognosis of patients with spinal metastasis as the initial manifestation of malignancy (SM-IMM). Patients and Methods We retrospectively reviewed the electronic medical records of 338 patients who underwent surgical treatment for metastatic spinal disease. The enrolled patients were divided into two groups. The SM-IMM group included patients with no history of malignancy whose site of primary malignancy was diagnosed after the identification of spinal metastasis. The other group included patients with a history of treatment for primary malignancy who then developed spinal metastasis (SM-DTM). The incidence of SM-IMM by site of primary malignancy was calculated. The difference between prognoses after surgical treatment for SM-IMM and SM-DTM was established. Results The median follow-up period was 11.5 months (interquartile range (IQR) 3.2 to 13.4) after surgical treatment. During the follow-up period, 264 patients died; 74 patients survived. The SM-IMM group consisted of 94 patients (27.8%). The site of primary malignancy in the SM-IMM group was lung in 35/103 patients (34.0%), liver in 8/45 patients (17.8%), kidney in 10/33 patients (30.3%), colorectum in 3/29 patients (10.3%), breast in 3/22 patients (13.6%), prostate in 3/10 patients (30%), thyroid in 4/8 patients (50%), and ‘other’ in 28/88 patients (31.8%). On Kaplan–Meier survival analysis, the SM-IMM group showed a significantly longer survival than the SM-DTM group (p = 0.013). The mean survival time was 23.0 months (95% confidence interval (CI) 15.5 to 30.5) in the SM-IMM group and 15.5 months (95% CI 11.8 to 19.2) in the SM-DTM group. Conclusion Of the 338 enrolled patients who underwent surgical treatment for spinal metastasis, 94 patients (27.8%) underwent surgical treatment for SM-IMM. The SM-IMM group had an acceptable prognosis with surgical treatment. Cite this article: Bone Joint J 2019;101-B:1379–1384.
