Objective: Robot-assisted radical cystectomy (RARC) is considered the gold-standard for patients who fail Bacillus Calmette–Guérin (BCG) treatment for high-grade non-muscle-invasive bladder cancer. We reviewed our histopathological outcomes to assess whether we are proceeding to cystectomy at an appropriate time. Methods: A retrospective analysis of the RARC database (2015–2020) was performed to identify patients who received intravesical BCG before cystectomy. Data regarding demographics, number of BCG instillations and staging were collected. Histopathological stage at cystectomy was compared between patients who received an induction course of BCG only (group A), and those who had continued maintenance doses (group B). Results: A total of 73 patients (57 males and 16 females) met the final inclusion criteria, with 24 patients in group A and 49 patients in group B. At cystectomy, 19 patients had ⩾T2 disease (group A: 7; group B: 12). There was no significant difference between groups ( p=0.78). Pelvic lymph node dissection was performed in 68 patients, with six patients found to have lymph node metastases. Conclusion: RARC plays a key role in managing BCG failure, considering the number of patients with muscle-invasive disease at final staging. However, prolonged BCG treatment was not associated with more advanced disease in our case series. Thus, persistence with intravesical treatment warrants consideration for selected patients. Level of evidence: Level 4.

Abstract Objective The aim of this study was to compare tentorial incision (group A) versus retraction and tack up suture (group B) of the tentorial edge during the subtemporal approach for surgery in the high basilar region. Design 24 cadaveric dissections and 4 clinical cases of aneurysms of the high basilar region are presented. Assessment included visibility and operability afforded by either tentorial incision creating a dural flap (group A) or retraction of the tentorial edge and tethering with a suture (group B). Four patients, two with superior cerebellar artery aneurysms and two with proximal posterior cerebral artery aneurysms were treated with each approach. Results In the quantitative evaluations, we found no significant difference in the exposure of the posterior cerebral, superior cerebellar, and perforant arteries as well as surgical working area provided by either approach. However, tentorial incision allowed a significantly greater exposure of the basilar artery and the fourth cranial nerve (both p < 0.001). Concerning operability, tentorial incision provided no objective advantage for direct clipping of the high basilar region (groups A vs. B, p > 0.05). Subjectively, clipping of the high basilar segment was feasible using tentorial tethering only. Conclusion Retraction of the free edge of the tentorium downward by tethering with a suture is simple and fast method for exposure of aneurysms in the high basilar region when the pathology does not require a proximal control. In our data the rather more invasive and time consuming tentorial incision provided an additional objectified advantage only for placement of a proximal temporary clip.

Purpose. To compare the visual and surgical outcomes after a reuse or a replacement of a dislocated in-the-bag intraocular lens (IOL). Methods. This was a retrospective, nonrandomized case series at a single ophthalmological institution. Cases with an in-the-bag dislocation of an IOL were treated by pars plana vitrectomy and the reuse or the replacement of the IOL. The lens was held by intrascleral fixation of the haptics of the IOL under both conditions. The same dislocated IOL was reused in 6 eyes (group A) or it was replaced with another IOL in the other 9 eyes (group B). The pre- and postoperative parameters analyzed included the visual acuity, refractive error, corneal endothelial cell density, and intraocular pressure (IOP). Results. There was no significant difference between the two groups in the postoperative visual acuity (P=0.388), refractive error (P=0.955), IOP (P=0.529), and endothelial cell loss (P=0.940). A breakage or a tilting of the IOL was observed and required replacement in three eyes in the reuse group (P=0.044). Conclusions. Half of the cases with reused in-the-bag dislocated IOL had a breakage or a tilting of the IOL. The replacement of the in-the-bag dislocated IOL is better than the reuse of the IOL with intrascleral haptics fixation.

Objective The purpose of this randomized study was to evaluate the effect on graft patency by adding clopidogrel to aspirin in off-pump coronary artery bypass (OPCAB) grafting and the possible side effects of such therapy. Methods Twenty patients who underwent standard OPCAB through median sternotomy were randomized immediately after surgery in two groups. Patients in group A (n = 10) received 100 mg of aspirin starting preoperatively, continuing indefinitely. Patients in group B received 100 mg of aspirin and, in addition, 75 mg of clopidogrel starting immediately after the operation and for 3 months. Postoperative bleeding and other perioperative parameters were compared. Angiography was repeated 3 months after surgery to determine the patency and quality of grafts. Results Preoperative risk factors were similar in the two groups. There was no significant difference in average number of distal anastomosis (P = 0.572), operation time (P = 0.686), postoperative bleeding (P = 0.256), ventilation time (P = 0.635), and intensive care unit stay (P = 0.065). Length of stay was shorter in group B (P = 0.024). There was no postoperative complication in either groups. Eight of 27 grafts in group A and 2 of 29 grafts in group B (P = 0.037) were occluded at the time of control angiography. Conclusions Early administration of a combined regimen of clopidogrel and aspirin after OPCAB grafting is not associated with increased postoperative bleeding or other major complications. Despite the small number of patients in this study and small number of examined grafts, the results suggest that the addition of clopidogrel may increase graft patency after OPCAB grafting.

523 Background: Neoadjuvant cisplatin-based chemotherapy (NAC) followed by cystectomy is the standard of care for muscle-invasive urothelial bladder cancer (MIBC). 15-35% of MIBC patients present with ureteral obstruction. Poor renal function increases cisplatin toxicity. It is unknown whether patients with ureteral obstruction which has been relieved (whether by nephrostomy tube or nephroureteral stent) have the same risk of toxicity as patients without ureteral obstruction. Methods: We retrospectively reviewed an institutional database of all patients undergoing NAC for MIBC with either dose dense MVAC (ddMVAC) or gemcitabine and cisplatin (GC) from January 2004 through May 2017. Patients without ureteral obstruction prior to initiation of NAC (Group A) were compared to those who had ureteral obstruction which was relieved prior to undergoing NAC (Group B). Continuous variables were compared using the Wilcoxon rank-sum test and categorical variables were compared using Fisher’s exact test. The primary outcome was premature discontinuation of NAC, which was defined as failure to complete all planned cycles. Logistic regression was used to test for differences between the groups in this outcome adjusting for age, ECOG performance status, and baseline glomerular filtration rate (GFR). Results: 160 patients in Group A and 59 patients in Group B were identified. Baseline age, Charlson Comorbidity Index, race, smoking status, and ECOG performance status were similar. Patients in Group B had lower GFR (99.2% vs 78.8% p <0.001) and were more likely to be female (21.9% vs 27.3% p <0.025) and to receive ddMVAC (65.0% vs. 83.1% p =0.012). There was no significant difference between groups in rates of premature NAC discontinuation (15.8% vs 22.0% p = 0.284) or grade ≥3 adverse events (23.4% vs 30.5% p = 0.285). Adjusted analysis showed no significant difference between the groups in frequency of premature NAC discontinuation (OR 1.96, 95% CI 0.84-4.57 p=0.12). Conclusions: We detected no difference in frequency of premature discontinuation of NAC in patients with relieved malignant ureteral obstruction relative to patients without obstruction. NAC for MIBC is likely safe in this population.

Purpose: To evaluate the characteristics of peripheral anterior chamber measurements by Pentacam after posterior implantable collamer lenses (ICL) and toric ICL (TICL) with central hole (V4c) implantation.Methods: Prospective, non-randomized consecutive case series. Forty-six patients undergoing ICL implantation in one eye (Group A) and identically sized TICL in the contralateral eye (Group B) in the Refractive Surgery Center of Eye and ENT Hospital of Fudan University were prospectively included. According to ICL/TICL size, these eyes were further divided into four subgroups. Peripheral anterior chamber depth (PACD) and angle (ACA) in nasal and temporal sides were measured using Pentacam pre-operatively and 12-month post-operatively.Results: The safety indices were 1.34 ± 0.32 and 1.25 ± 0.16 and the efficacy indices were 1.20 ± 0.24 and 1.19 ± 0.19 for ICL and TICL groups, respectively. There was no significant difference in pre-operative PACD or ACA between the two groups. Post-operative PACD and ACA were significantly lower than pre-operative values. Variations of PACD and ACA of TICL group were significantly larger than those of ICL group. The change of ACA for 13.2 mm lenses was significantly larger than that of 12.6 mm lenses. Pre-operative CACD and vault were significantly associated with post-operative PACD, while pre-operative ACA and vault were significantly associated with post-operative ACA.Conclusions: Variations of PACD and ACA were greater in eyes after TICL (V4c) implantation compared with identically sized ICL (V4c) implantation and with larger size than smaller size lens implantation. Pre-operative anterior chamber structure and vault affect post-operative PACD and ACA.

Objective: Intravesical bacillus Calmette–Guérin (BCG) is the first-line treatment of choice for high-risk non-muscle-invasive bladder cancer (NMIBC). Our aim was to evaluate the long-term impact of BCG shortages on oncological outcomes. Methods: All patients undertaking an initial course of intravesical BCG for intermediate or high risk NMIBC at a single UK cancer centre between August 2012 and August 2014 were evaluated. Compliance was defined as completing 12 doses of BCG within the first year following diagnosis. Results: Due to BCG shortages, 25/114 (22%) patients were compliant with planned maintenance treatment. Compared to the compliant cohort, the non-compliant due to BCG shortages cohort had a higher rate of disease recurrence (35.3% vs. 24%), required more additional intravesical treatments (14.7% vs. 12%) and had a higher rate of radical cystectomy (11.8% vs. 4%). Disease-free survival was superior in the compliant cohort at two years (88% vs. 79.5%) and at 4.5 years (72% vs. 56.1%). There was no statistically significant difference, likely due to the sample size. Conclusions: The consequences of undertreatment due to BCG shortages can impact long-term cancer outcomes. Increased vigilance, robust long-term surveillance and alternative treatment strategies are required for NMIBC patients affected by shortages in BCG supplies. Level of evidence: Level 2b

Abstract Background Tuberculosis (TB) remains a significant public health concern, and exposure in healthcare settings is prevalent. Current guidelines recommend testing for TB by acid-fast bacilli (AFB) smear microscopy with 3 sputum samples and/or using nucleic acid amplification test (NAAT), and mycobacterium culture. The purpose of this project is to compare how different TB diagnostic tests affect the duration of stay in respiratory isolation. Methods This study was conducted at the Veteran Affairs South Texas hospital, which includes a total of 437 beds. Data were collected retrospectively from medical records. Eligibility included patients admitted to the hospital and placed in airborne isolation for TB screening and diagnosis, had 3 sputum samples collected 8 hours apart and/or had 2 PCR MTB/RIF. Patients were excluded if they had TB or were not undergoing evaluation for TB. Three time periods analyzed included, 3 AFB sputum samples analyzed in-house from December 2012 to January 2014 (Group A), 3 AFB sputum samples analyzed at outside facility during 2013 to 2014 as well as 2 months in 2012 (Group B), and 2 MTB PCR/RIF in house during 2017 and 2018 (Group C). Duration of isolation was compared between groups using the Kruskal–Wallis test. A total number of 815 patients were screened, leaving 105 patients for analysis after exclusion. There were 49 patients analyzed from Group A, 28 from Group B, and 28 from Group C. Results Crude analysis of the data showed numerical differences in the total number of days and hours in isolation between the 3 groups. The average (mean) days in isolation were 4.2 for Group A, 7.4 for Group B, and 5.5 for Group C. There was no statistically significant difference in either days or hours of airborne precautions by “rule out” method. Days of isolation in airborne precautions (median IQR) was 4 for all groups (P = 0.3313). Likewise, hours of airborne precautions had a median IQR of 96 for all groups P = 0.4347. Conclusion Although there was no statistical significance between the groups, crude analysis did show a numerical difference in the mean total airborne days and hours. Lack of statistical difference may be due to low number of patients, timing of order placement for in-house PCR, and longer than expected stay in airborne precautions.

Objective. To investigate the application value of the combined detection of serum IGF-I and IGFBP-3 in the diagnosis of bladder cancer (BC). Methods.Sixty BC patients in our hospital (January 2019-January 2020) were chosen as group A, while sixty healthy people during the same period were chosen as group B. The serum IGF-I and IGFBP-3 levels of the subjects were detected to explore the relationship between the two levels (serum IGF-I and IGFBP-3) and BC.Results.Compared with group B, the two levelsof group A were lower while IGF-l/IGFBP-3 was higher. Compared with low-grade BC group, non-muscle invasive BC (NMIBC) group and non-lymph node metastasis group, the two levels were lower in high-grade BC group, muscle-invasive BC (MIBC) group and lymph node metastasis group (P<0.05). No notable difference in IGF-l/IGFBP-3 was found among patients with high-grade or low-grade BC, with or without lymph node metastasis, andwith or without muscular invasion (P>0.05). Conclusion. The serum IGF-I and IGFBP-3 levels of BC patients are obviously different compared with healthy people, and vary in patients with different types of BC, indicating the two factors can be applied in clinical diagnosic of BC.

Objective: We wanted to see whether impacted third mandibular molar extractions resulted in Alveolar Osteitis if post-extraction socket irrigation was used or not. Methodology: A randomized control experiment on 70 patients study was conducted from July 2019 to January 2020 at Islamabad Dental Hospital's OMFS department. Patients presenting with the mandibular third molars fulfilling the inclusion criteria had their teeth extracted with and without socket irrigation using the computer lottery method. In cases of dry socket, clinical diagnosis was made between the 3rd, 5th, and 7th postoperative days. Results: 70 patients/sockets were evaluated with 35 having been irrigated and 35 non-irrigated. The age range was 16-50years with a mean of 29.49 and most patients were between the 16-35 age group. There were 48.6% males and 51.4% females. Dry Socket was evaluated on the 3rd, 5th, and 7th day between groups (A=irrigation, B=Non-irrigation). On the 3rd postop day, 14 (40%) patients in group A and 15(42.9%) patients were diagnosed as dry Sockets. A similar number of patients in both groups (20%) exhibited symptoms of dry socket on the fifth and seventh postoperative days, as did 5 (14.3 %) in group A, 3 (8.6 %) in group B, and 1(2.9 %t) in group A, all on the fifth postoperative day. Conclusion: On the third, fifth, and seventh postoperative days, there was no significant difference in the result of Alveolar Osteitis between the groups.

Purpose: To investigate the clinical outcomes of Visian implantable collamer lens (ICL) implantation according to lens size and implantation angle. Setting: Onnuri Smile Eye Clinic, Seoul, Republic of Korea. Design: Retrospective case series. Methods: This study included 566 eyes of 283 patients treated with ICL implantation. Patients were divided into three groups: horizontally implanted same-sized ICL (group A), horizontally implanted different sized-ICL (group B: large ICL and small ICL) and same sized-ICL implanted with a different implantation angle (group C: horizontal and vertical). Results: At 12-month follow-up, the mean vault was 0.78 ± 17, 0.48 ± 0.13, 0.71 ± 0.18 and 0.44 ± 0.16 mm when large and small sized ICL was used in group B ( p < 0.001), and when ICL was horizontally and vertically implanted in group C ( p = 0.021), respectively. And the mean SE was −0.11 ± 0.30, −0.34 ± 0.42, −0.3 ± 0.56 and −0.64 ± 0.66 dioptres (D), when the large and the small sized ICL was used group B ( p = 0.039), and when the ICL was horizontally and vertically implanted in group C ( p = 0.036), respectively. No significant difference in UDVA, IOP and ECD between both eyes in groups B and C was observed. No statistical difference was found in the vault between both eyes for groups B and C. Conclusions: The vault was significantly higher and the SE was significantly more hyperopic when a larger-sized ICL was used or the ICL was horizontally implanted compared to when the ICL was vertically implanted.
