Abstract
PURPOSE The healthcare system emits greenhouse gas emissions and produces waste that in turn threatens the health of populations. The objective of our study was to measure the ecological threat related to intravitreal injections. METHODS Emissions were separated into scope 2 corresponding to Heating, Ventilation and Air Conditioning (HVAC) of the building, and scope 3 corresponding to travels (patients and staff), and life cycle assessment (LCA) of medical devices (MD) and pharmaceutics. Greenhouse gas (GHG) emissions and waste for a single injection were first measured through a waste audit, and secondly anticipated theoretically with a calculator. RESULTS The average GHG emissions and waste measured were 277kgCO2eq/IVI and 0.5kg/IVI, respectively. Pharmaceuticals were responsible for 97% of total emissions. Emissions unrelated to pharmaceuticals counted for 8.4kgCO2eq/IVI. GHG emissions and waste estimated with the calculator were 276kgCO2eq/IVI and 0.5kg/IVI, respectively, showing that the calculator was accurate. CONCLUSION Our study provides a puzzle piece to carbon footprint and waste assessment in the field of ophthalmology. It may help provide concrete data for future green vs. vision discussions.

Abstract
Purpose Prone cross-table lateral x-ray (CTLxR) and colostogram aid surgical planning for anorectal malformations (ARMs) without perineal fistulas. We suggest objective imaging tools to classify ARMs. Methods Three observers prospectively evaluated CTLxR and colostograms of male ARM patients (2012-2022) without perineal fistulas. The level of the rectal pouch was estimated with pubococcygeal (PC) and ischiatic (I) lines. On CTLxR, we described the "pigeon sign", defined as the rectal pouch ending with a beak-like image, suspicious for a rectourinary fistula. ARM was defined as rectobulbar when the rectal pouch was below the I line, rectoprostatic when between PC and I lines, and rectovesical when above the PC line. Concordance was assessed with Fleiss' kappa. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the "pigeon sign" were calculated. Results Thirteen patients were included in this study. The interobserver agreement on CTLxR was 69.2% (k = 0.54) on pouch ending, 84.6% (k = 0.69) on the "pigeon sign", and 76.9% (k = 0.69) on diagnosis; concordance between observers and intraoperative diagnosis was 66.6% (k = 0.56). The "pigeon sign" had 75% sensitivity, 100% specificity, 100% PPV, and 50% NPV. The interobserver agreement on colostograms was 84.6% (k = 0.77) on pouch ending and 89.7% (k = 0.86) on diagnosis; concordance between observers and intraoperative diagnosis was 92.3% (k = 0.90). Conclusion PC and I lines and the "pigeon sign" are useful tools in examining CTLxR and colostograms. Adequate CTLxR interpretation may modify surgical strategy.

Abstract
Micropulse Transscleral Cyclophotocoagulation (MP-TSCP) is a recently developed cyclodestructive procedure less aggressive than conventional TSCP. In this study, we aimed to evaluate the safety and efficacy of MP-TSCP in a real-life setting. MATERIAL AND METHODS We retrospectively included all MP-TSCP cases performed in the Bicêtre Hospital Ophthalmology department between January 2017 and September 2019. Intraocular pressure (IOP) and hypotensive medications were recorded preoperatively, at month 1, 3, 6 and at the conclusion of follow-up, as well as postoperative adverse events. Success was defined as an IOP between 6 and 21mmHg with a decrease of at least one medication or an IOP reduction>20%. RESULTS Thirty eyes (28 patients) were included. Preoperative IOP was 27.2±10.6mmHg, with 3.5±0.6 hypotensive medications, the mean deviation on the Humphrey 24-2 visual field was -21.9±6.9dB, and 43% of eyes had a past history of filtering surgery. The mean follow-up was 13.5±8.1 months. Eleven patients (37%) had to be retreated with MP-TSCP during follow-up. At 3 and 6 months and at the conclusion of follow-up, the IOP was 18.3±7.3mmHg (-33%; P<0.0001), 22.5±11.8mmHg, (-17%; P=0.052), 22.7±12.0mmHg (-16,5%; P<0.050), respectively. The success rates were 57%, 50% et 53% at 3 months, 6 months and at the conclusion of follow-up, respectively. Severe adverse events included 3 cases of corneal ulcers and 2 cases of severe but transient ocular hypotony without visual impairment. CONCLUSION MP-TSCP is an effective procedure for severe and/or refractory glaucoma, but retreatments are required in more than one-third of cases. Further studies are warranted to define factors predictive of success and indications for retreatment.

Abstract
Postoperative infections are the most frequent complications in surgery and are the commonest cause of the lengthening of hospital stay. The purpose of this study is to prospectively evaluate the incidence and predisposing factors of postoperative infections in 1396 surgical patients admitted to our Institute from 1984 to 1988. Patients undergoing minor surgical procedures (wound less than 2 cm) were excluded from the study. Patients were evaluated daily during hospital stay for onset of infections and results recorded on data sheet. Hemocultures in septic patients and samples of exudate at site of infection were taken whenever possible for aerobic and anaerobic cultures. 368 patients (26.36%) had at least one postoperative septic complication; (79 of them [5.65%] had two or more infections). The following infections were recorded: wound infections: 148 (10.60%); respiratory tract infections: 144 (10.31%); urinary tract infections 125 (8.95%); miscellaneous infections 11 (0.78%); thrombophlebitis 23 (1.64%); FUO 10 (0.71%). The most important predisposing factor for wound infection was endogenous contamination (wound infections: 18/499 [3.60%] in clean, 42/594 [7.67%] in potentially contaminated, 57/217 [26.26%] in contaminated and 31/86 [36.04%] in dirty operations). The duration of the anaesthesia was found to correlate with an increased incidence of respiratory tract infections (4.49% anaesthesia less than 60 min; 7.21% anaesthesia greater than 60 less than 120 min; 15.31% greater than 120 min anaesthesia). Urinary infections were more frequent when the patients where catheterized at least once in the postoperative period (24.86% vs 3.2%).
