Background and Objectives: Robot-assisted extravesical ureteral reimplantation (REVUR) has been described as valuable alternative to open reimplantation in the pediatric population. This study aimed to report the outcome of REVUR in children with complex obstructed megaureter (COM) needing ureteral dismembering and/or tapering. Materials and Methods: The records of patients with COM, who received REVUR with ureteral dismembering and/or tapering over the last 3 years (2021–2024), were retrospectively reviewed. The inclusion criteria for COM included previous surgery, paraureteral diverticula, or ectopic megaureter. Results: A total of 16 patients (15 boys), with a median age of 7.8 years (range 2–16), were treated over the study period. COM was associated with paraureteral diverticula (n = 6), previous failed endoscopic balloon dilation (n = 4), ectopic megaureter (n = 2), and previous bulking agent endoscopic injection causing iatrogenic ureteral obstruction (n = 4). Presentation symptoms included febrile urinary tract infections (n = 8), flank pain (n = 4), hematuria (n = 2), and pseudo-incontinence (n = 2). All surgical procedures were accomplished robotically without conversions or intra-operative complications. Ureteral tapering was performed in 7/16 (43.7%). The median operative time (including robot docking) was 220 min (range 155–290). The median length of stay was 3.8 days (range 3–7). The indwelling double J stent was removed 4–6 weeks postoperatively. Clavien 2 grade complications occurred postoperatively in 2/16 (12.5%). At median follow-up of 34.5 months, all patients were asymptomatic and showed improved hydroureteronephrosis on ultrasound and improved drainage on diuretic renogram. Conclusions: This study demonstrates that robot-assisted extravesical ureteral reimplantation is a safe and effective treatment for primary obstructive megaureter and other complex ureteral anomalies in our patient cohort. The procedure showed low complication rates, high success rates, and favorable long-term outcomes, supporting the feasibility and effectiveness of robotic surgery for these conditions.

Two-stage prosthesis exchange is the treatment of choice for chronic periprosthetic joint infection (PJI) of a total hip arthroplasty (THA), especially when the bone and surrounding soft tissues are compromised or difficult-to-treat pathogens are implicated. The aims of our study were as follows: (1) to determine the outcome of 2-stage prosthesis exchange for the treatment of PJI after THA and (2) to determine the risk factors for reinfection leading to subsequent revision surgeries after reimplantation. We prospectively enrolled 187 consecutive patients who underwent a 2-stage THA exchange with resection arthroplasty for PJI from 2013 to 2019. The mean (± SD) duration of follow-up was 54.2 ± 24.9 months (range, 36 to 96), and the mean interval until reimplantation was 9.8 ± 8.9 weeks (range, 2 to 38). All patients remained in a spacer-free girdlestone situation between the 2 stages of treatment. Patients who remained infection-free after their 2-stage treatment were considered to have achieved treatment success. The overall success rate was 85.6%. The cumulative probability of reinfection was 11.5% after one year and 14% after 2 years after reimplantation. High virulence or difficult-to-treat pathogens were significant and independent risk factors for reinfection (HR [hazard ratio] = 3.71, 95% CI [confidence interval]: 1.47 to 9.36, P =.006 and HR = 3.85, 95% CI: 1.73 to 8.57, respectively, P =.001), as was previous 2-stage hip prosthesis exchange (HR = 3.58, 95% CI: 1.33 to 9.62, P =.01). Overall reoperation and revision rates were 26.2 and 16.6%, respectively. Re-infected patients had an 80% higher probability of reoperation than noninfected ones (P <.001, log-rank = 102.6), and they were 55% more likely to undergo revision surgery during their follow-up (P <.001, log-rank = 55.4). Reinfection rates after 2-stage spacer-free THA revision for PJI still remain high but are comparable to those including cement spacers. Patients who have had prior failed 2-stage implant exchanges or are infected by high-grade or difficult-to-treat pathogens are at high risk for treatment failure. [ABSTRACT FROM AUTHOR]

Dental implants have been widely used with success, but long-term usage sometimes leads to implant loss. The purpose of this review was to summarize the etiology of early and late failure requiring dental implant removal and the treatment strategies for the removal of failed implants and reimplantation. Early failures are often caused by patient-related factors, such as smoking, diabetes, radiotherapy, bone quality, and periodontitis of the remaining natural teeth. The most common cause of late failure is peri-implantitis, followed by implant fracture and implant malpositioning. Implants should be removed if they are mobile or if their superstructure cannot be maintained (e.g., implant fracture). For peri-implantitis, implant removal should be determined based on the patient’s age and esthetic needs, the implant site, and the severity of bone loss. Many reports have been published on implant removal techniques. The reverse torque technique should always be the first choice because of its low invasiveness. The weighted survival rate for the replacement of failed implants is 86.3%, with a much lower survival rate after the second or subsequent implantations. Therefore, patient-specific problems, such as smoking habits and bruxism, should be checked before reimplantation and controlled to the greatest extent possible.

BACKGROUND: End-stage renal disease (ESRD) and renal transplant (RT) patients are known to have more perioperative and postoperative complications after arthroplasty surgeries when compared to patients without. We hypothesize that RT patients undergoing shoulder arthroplasty (SA) have fewer systemic and surgical complications when compared to ESRD patients undergoing SA. METHODS: This was a retrospective review from the PearlDiver Patient Record Database. International Classification of Diseases and Current Procedural Terminology codes were used to identify patients who had undergone primary total and reverse shoulder arthroplasty, respectively, and subsequent surgical revisions. Unadjusted univariate analysis of patient demographics, Charlson Cormorbidty Index, and surgical complications at 90 days, 1 year, and 2 years after was performed using chi-squared testing. Multivariate logistic regression analyses were subsequently performed for systemic complications and prosthesis outcomes at all time points. RESULTS: Of 1191 patients with ESRD or previous RT and who underwent either total shoulder arthroplasty or reverse total shoulder arthroplasty, 1042 (87.5%) had ESRD and 149 (12.5%) had a previous RT. ESRD SA patients were more likely to have hypertension, liver disease, coronary artery disease, and hypothyroidism. Interestingly no statistical significance was found in multivariate analysis for systemic complications at 90 days, nor for surgical complications at the 90-day, 1-year, or 2-year mark between ESRD and RT cohorts. CONCLUSION: SAs have comparable outcomes in ESRD and RT patients. The differing conclusions among studies might be partially accounted for by the demographic differences and comorbidities between these 2 patient populations. Providers should continue to provide appropriate counseling concerning risks, benefits, and timing of SA for these patients.

Background/purpose: Although reimplantation is currently a common treatment procedure, little information on reimplantation success or failure is available in the literature. The purpose of the present investigation was to evaluate the survival rate of dental implants that were performed in sites of previously failed implants and identify factors associated with the treatment outcome. Materials and methods: This retrospective study is based on a cohort of patients rehabilitated with dental implants in the dental clinics of the universities contributing data to the BigMouth network between 2011 and 2022. Implants replacing a previously failed implant at the same site were included. Cases of first and second reimplantations were included Information regarding patients' characteristics including age, gender, ethnicity, race, tobacco use, and systemic medical conditions were extracted from patients’ files. Results: Records of 50,333 dental implants placed in 20,842 patients over a 12-year period were screened. Three hundred seventy implants placed in 284 patients were replaced by another implant at the same site. The cumulative survival rates of implants inserted for the first time was 98.6 %, for the first replacements was 96.1 % and for the second replacements was 91.7 %. First reimplants exhibited a significantly higher risk of failure than initial implantation (P 0.05). Conclusion: Within the limitations of the present study, dental implants replacing failed implants exhibited lower survival rates than the rates reported for the previous attempts of implant placement. No risk indicators for implant failure were identified. Additional factors should be examined in future studies.

We sought to determine the utility of intracranial-to-intracranial bypass (IIB) surgery and the available bypass options for complex cases. A total of 18 IIB cases were included. Each case was classified as IIB with or without an interposition graft. The clinical and angiographic status were evaluated pre- and postoperatively and at the last follow-up. Angiographic images were analyzed and reconstructed schematically. Postoperative angiography was used to measure the bypass patency and the presence of postoperative cerebral infarction. The recipient artery occlusion time for each bypass was measured. Of the 18 patients, 14 had presented with a complex intracranial aneurysm (IA), 1 with vertebrobasilar dolichoectasia, and 3 with intracranial arterial steno-occlusive disease. Ten patients had an incidentally discovered IA. Seven patients had presented with neurological deficits due to ischemia or aneurysmal mass effects. Of the 18 cases, 10 were IIBs with an interposition graft, including 4 cases of superficial temporal artery and 6 of radial artery graft bypass, and 8 were IIBs with a noninterposition graft, including 3 cases of in situ bypass, 1 case of reanastomosis, and 4 cases of reimplantation. The pre- and postoperative modified Rankin scale score did not change or improve, and all the bypasses were patent. No patient had died during the mean follow-up period of 50.0 months. The mean occlusion time of the recipient artery was 59.5 minutes. A total of 8 patients experienced postoperative cerebral infarction but all had almost recovered at discharge. With proper selection of the IIB type, IIB can be a suitable treatment option for some patients with complex IAs and intracranial arterial steno-occlusive disease when extracranial-to-intracranial bypass is not feasible.

Introduction: Due to the increasing number of cochlear implant (CI) recipients, growing indications, and the aging population, the reimplantation of CI recipients has become a focus of attention. The aim of this study is to examine the causes, timing, and postoperative speech understanding in a large cohort over the past 30 years. Methods: A retrospective data analysis was conducted on over 4000 CI recipients and 214 reimplanted children and adults from 1993 to 2020. This involved collecting and comparing data on causes, manufacturer information, and demographic data. In addition, a comparison of speech understanding in Freiburg monosyllables and numbers before and after reimplantation was carried out. Results: Children did not exhibit elevated rates of reimplantation. The overall reimplantation rate in the entire cohort was 5%. The CI overall survival rate after 10 years in the entire cohort was 95.2%. Device failure was the most common reason for reimplantation, with 48% occurring within the first 5 years after implantation. The second most common reason was medical complications, with the risk of reimplantation decreasing as more time passed since the initial implantation. There were no significant differences in Freiburg numbers and monosyllable comprehension before and after reimplantation, both in the overall cohort and in the subcohorts based on indications. Even a technical upgrade did not result in a significant improvement in speech understanding. Discussion: There was no significant difference in the frequency of reimplantation based on patient age, especially when comparing children and adults. Device failure is by far the most common indication for reimplantation, with no significant difference in implant survival between manufacturers. Patients most often choose the same manufacturer for reimplantation. The likelihood of reimplantation decreases with increasing time since the initial implantation. The indication for reimplantation should be carefully considered, as on average, no improved speech understanding is achieved, regardless of the cause, even with a technical upgrade.

A 2-stage exchange revision for periprosthetic joint infection (PJI) is associated with major risks for reinfection. Although serum markers are frequently used for diagnosis, their effectiveness remains debatable. Synovial fluid markers may offer a more accurate diagnosis of PJI; however, the importance of these biomarkers, notably synovial fluid C-reactive protein (syCRP), remains controversial, particularly in the context of reimplantation. The present study aimed to clarify these diagnostic uncertainties by evaluating the diagnostic efficacy of syCRP versus serum CRP (seCRP) levels in the context of PJI and recurring or persisting infections before reimplantation. A total of 186 patients were enrolled and divided into 2 groups: aseptic revision (n = 112) and PJI revision (n = 74). Of the PJI group, 65 were categorized as success and 9 as failure, based on the presence of recurrent or persistent infection before reimplantation. The syCRP and seCRP levels and their changes were assessed preoperatively and in the first-stage and second-stage revisions. Additionally, receiver operating characteristic (ROC) curves and area under the ROC curves (AUCs) were analyzed. Both seCRP and syCRP levels were significantly elevated in the PJI group compared with the aseptic group (P <.001). The ROC curve analysis highlighted the enhanced diagnostic accuracy of syCRP for PJI, with an AUC of 0.93 versus 0.80 for seCRP. Furthermore, syCRP proved to be more reliable in predicting reimplantation success, exhibiting an AUC of 0.86 versus 0.63 for seCRP. In evaluating trends in CRP levels to determine reimplantation timing, changes in syCRP levels demonstrated superior diagnostic utility, exhibiting an AUC of 0.79 versus 0.63 for changes in seCRP levels. In assessing PJI and infections before reimplantation, syCRP may offer enhanced accuracy compared with seCRP. Nevertheless, variations in both syCRP and seCRP levels did not consistently predict the outcome of reimplantation. [ABSTRACT FROM AUTHOR]

Case: A 32-year-old man presented with a type II open both-bone forearm fracture and segmental bone loss because of complete extrusion of a diaphyseal fragment (3 cm) of ulna. The patient presented to our level 1 trauma center after a motor vehicle collision. The extruded segment underwent sterilization and immediate reimplantation with internal fixation approximately 6 hours after arrival. Our patient achieved union by 7-month follow-up, demonstrated excellent functional outcomes, and was free from infection at 1-year follow-up. Conclusion: In select cases, successful reimplantation can be achieved by meticulous debridement, sterilization, and immediate reimplantation with internal fixation. [ABSTRACT FROM AUTHOR]

Within the limitations of the present study, dental implants replacing failed implants exhibited lower survival rates than the rates reported for the previous attempts of implant placement. No risk indicators for implant failure were identified. Additional factors should be examined in future studies. [ABSTRACT FROM AUTHOR]

Hypocalcemia is a common consequence of parathyroidectomy. We aim to study the causality between hypocalcemia and parathyroid surgery. We selected 110 patients, registered in the records of the Endocrinology Clinic, investigated and diagnosed with primary, secondary or tertiary hyperparathyroidism and subsequently operated between 2014-2022 in the IVth Surgery Clinic of the “Saint Spiridon Hospital” from Iași, which we included in this comparative study. The collected data was entered into a database and statistically analyzed. The selected group was divided into two categories, as follows: 84 patients (78%) without reimplantation, and 26 patients (22%) with reimplantation. Regarding the values of post-operative calcium levels in those not reimplanted versus those reimplanted, the following average values were found: 9.52 (value range 5.60 mg/dl-16.10 mg/dl) in those not reimplanted vs. 9.18 (value range 6.17 mg/dl – 12.86 mg/dl) in those reimplanted. In addition to serum calcium values, other parameters with significance in parathyroid pathology were monitored, as follows: PT, Mg, P and PTH. The documented values of postoperative calcemia in the two major categories were close, the reimplanted category registering slightly lower values.

Abstract Total joint arthroplasty is the recommended treatment for patients with end-stage osteoarthritis, as it reduces disability and pain and restores joint function. However, prosthetic joint infection is a serious complication of this procedure, with the two-stage exchange being the most common treatment method. While there is consensus on diagnosing prosthetic joint infection, there is a lack of agreement on the parameters that can guide the surgeon in performing definitive reimplantation in a two-stage procedure. One approach that has been suggested to improve the accuracy of microbiologic investigations before definitive reimplantation is to observe a holiday period from antibiotic therapy to improve the accuracy of cultures from periprosthetic tissues, but these cultures report some degree of aspecificity. Therefore, several pieces of evidence highlight that performing reimplantation using continuous antibiotic therapy should be considered a safe and effective approach, leading to higher cure rates and a shorter period of disability. Dosage of C-reactive protein (CRP), erythrocyte sedimentation rate (ERS) and D-dimer are helpful in diagnosing prosthetic joint infection, but only D-dimer has shown sufficient accuracy in predicting the risk of infection recurrence after a two-stage procedure. Synovial fluid analysis before reimplantation has been shown to be the most accurate in predicting recurrence, and new cutoff values for leukocyte count and neutrophil percentage have shown a useful predictive rule to identify patients at risk of unfavourable outcome. A new scoring system based on a numerical score calculated from the beta coefficient derived through multivariate analysis of D-dimer levels, synovial fluid leukocytes and relative neutrophils percentage has demonstrated high accuracy when it comes to guiding the second step of two-stage procedure. In conclusion, reimplantation may be a suitable option for patients who are on continuous therapy without local symptoms, and with CRP and ERS within the normal range, with low synovial fluid leukocytes (

We herein present a video of a robotic-assisted uretero-ileal reimplantation in an ileal conduit. The patient was a 74 year old male who had undergone robotic assisted radical cystectomy with intracorporeal ileal conduit in 2022. Pathology showed urothelial cell carcinoma pT2N0. In amrch 2023 the patient was admitted in our clinic with left side flank pain and sepsis. A CT scan showed severe lefthydronephrosis on a left sided uretero-ileal stricture. A nephrostomy tube was patient and, after management of sepsis, an endoscopic balloon dilatation of the stricture was performed in may 2023. Patient experienced a stricture recurrence in September 2023. We thus decided to perform robotic assisted uretero-ilal reimplantation.Patient was positions in dorsal decubitus and robotic trocarts were positioned as for radical cystectomy. Extensive adhesiolysis was performed. A stay suture was then positioned on the ileal conduit to traction it towards the abdominal wall. Dissection of the retroperitoneum was then performed medial to the ileal conduit, in order to identify the left ureter. The right ilac vessels are exposed to avois inadvertent injury. ICG is instilled via the left nephrostomy, helping the surgeon to identify the left ureter. Gven the massive fibrosis of the ureter, this structure is not mobilized and the ileal loop is brought down to the ureter. A side to side anastomosis is performed using 4/0 vycril. A 7F monoJ catheter is positioned and externalized using a foley catheter as carrier. OR time was 155 minuted and estimated blood loss 50cc. Post operative course was uneventful and patient was discharged on POD 2.

Introduction: The aim of this study is to assess the outcomes of parathyroid gland reimplantation with PR-FaST technique in patients undergoing thyroid surgery, focusing on graft functionality over a 5-year follow-up period. Materials and Methods: We analyzed data from 131 patients who underwent parathyroid reimplantation using the PR-FaST technique during thyroid surgery due to inadvertent parathyroid removal or evident vascular damage. Postoperative evaluations included serum calcium (Ca), magnesium (Mg), and phosphorus (P) analyses on the 1st and 2nd postoperative days, at 10 days, and at 1, 3, 6 months, 1 year, and 5 years of follow-up. Additionally, the mean values of serum intact parathyroid hormone (iPTH) concentration were measured from blood samples collected from both the reimplanted arm (iPTH RA) and non-reimplanted arm (iPTH NRA) within the same period. Results: Among 131 patients, at 10 days post-surgery, only 46 patients (35.1%) out of 131 exhibited graft viability (iPTH ratio >1.5). This percentage increased to 72.8% (94 patients) after 1 month and further to 87.8% (108 patients) after 3 months post-surgery. At 1 year, 84.7% of patients showed good graft functionality. After 5 years, the percentage remained stable, with graft viability observed in 81.3% of patients. Only 91 of the initial 131 patients completed follow-up up to 5 years, with a dropout rate of 30.5 %. Conclusions: Parathyroid reimplantation using the PR-FaST technique is a viable option for patients undergoing thyroidectomy and has been shown to be a reproducible and effective technique in most patients, with sustained graft functionality and parathyroid hormone production over a 5-year follow-up period.

A numerical score derived from analysing these three parameters can serve as a valuable tool in determining the feasibility of reimplantation in these patients. [ABSTRACT FROM AUTHOR]

This article presents a comparative study on the effects of parathyroidectomy and parathyroid autotransplantation on calcium and parathyroid hormone (PTH) levels in patients. The study included 110 patients who underwent parathyroidectomy between 2014-2022. The data collected showed that both groups experienced hypocalcemia after surgery, but the reimplanted group had slightly lower calcium levels. Hypocalcemia resolved in all reimplanted patients after 6 months, while some non-implanted patients still had permanent hypocalcemia. The study also noted that women are more likely to have parathyroid gland pathology. However, the study acknowledges that the results may be influenced by other factors not considered in the study.

Introduction: Avulsion of teeth is one of the most complex forms of dental injury, and the selection of an appropriate storage medium greatly influences the preservation of Periodontal Ligament (PDL) cell viability, which is crucial for the successful re-implantation of avulsed teeth. Therefore, identifying effective storage options such as natural coconut water and pre-packaged coconut water holds significant promise in improving outcomes for this challenging dental injury. Aim: To evaluate the efficacy of natural coconut water, pre-packaged coconut water, and Hank’s Balanced Salt Solution (HBSS) as storage media in maintaining PDL cell viability. Materials and Methods: A total of 32 non-carious freshly extracted human premolars were randomly divided into four study groups (n=8) and stored in the following storage media respectively: Group I-Natural coconut water group, Group II-Pre-packaged coconut water group, Group III-Bench dry group, and Group IV-HBSS groups for 30 minutes. The PDL cells were collected and incubated in phosphate buffer saline for 30 minutes and then centrifuged at 800 rpm for five minutes. Following this, the cells were stained with trypan blue to observe their viability. The Analysis of Variance (ANOVA) with Tukey’s post-hoc test was used for analysing the data. Results: The mean percentage of viable cells in natural coconut water (80.6250) was higher than in HBSS (79.8750), pre-packaged coconut water (79.2500), and the bench dry group (6.1250). Meanwhile, the mean percentage of non-viable cells was highest in the bench dry group (93.8750), followed by the pre-packaged coconut water (20.7500), HBSS (20.1250), and natural coconut water (19.3750). Conclusion: Natural coconut water and pre-packaged coconut water are equally effective in maintaining the viability of PDL cells. Therefore, pre-packaged coconut water can be used as a substitute for natural coconut water for tooth storage, depending upon availability.

Abstract Background The cause of early septic failure after two-stage exchange revision total knee arthroplasty (TKA) for chronic periprosthetic joint infection (PJI) and the factors affecting it are not well known. The purpose of this study was to determine the surgical outcomes and the risk factors for early septic failure after two-stage revision TKA for chronic PJI. Methods We identified a total of 246 adult patients who met the Musculoskeletal Infection Society (MSIS) diagnostic criteria for chronic PJI at two academic tertiary hospitals from March 2012 to December 2018. Finally, 151 patients who consecutively received two-stage exchange revision TKA for chronic PJI and who had a minimum 3-year follow-up were enrolled and retrospectively reviewed. Successful surgical treatment was evaluated for two-stage revision TKA and risk factors for early septic failure were identified. Results Early septic failures occurred within 3 years after reimplantation in 48 patients (31.8%). After accounting for potentially confounding variables, we found that male patient [odds ratio (OR): 2.753, 95% confidence interval (CI) 1.099–6.893, p = 0.031], fungus or mycobacterial infection (OR: 5.224, 95% CI 1.481–18.433, p = 0.01), and positive culture at reimplantation (OR: 4.407, 95% CI 1.255–15.480, p = 0.021) were independently associated with early septic failure after two-stage exchange revision TKA. Conclusion Male patients, fungus or mycobacterial infection, and positive culture at reimplantation were independently associated with an increased risk of early septic failure after two-stage exchange revision TKA despite normal C-reactive protein values prior to reimplantation. Further prospective and high-quality studies are needed to determine the risk factors of two-stage exchange revision TKA for chronic PJI. Level of evidence: level IV; retrospective comparison; treatment study.

Abstract Background The optimal timing for reimplantation for periprosthetic joint infection (PJI) has not been established and varies from a few weeks to several months. The aim of this study was to assess the commendable time between implant removal and reimplantation in patients who underwent two-stage exchange arthroplasty for PJI. Methods We retrospectively reviewed 361 patients who were treated with two-stage exchange arthroplasty for hip and knee chronic PJI at our institution between January 2000 and December 2018. Patient characteristics, comorbidities, surgical variables, microbiology data, and time to reimplantation were recorded. All patients were followed for a minimum of one year. Treatment failure was defined by Delphi criteria. Logistic regression analyses were used to calculate survival rates and adjusted odds ratios (ORs) of treatment failure. Results In final analysis, 27 (7.5%) had treatment failure. Factors related to treatment failure including interim spacer exchange (OR, 3.13; confidence interval (CI), 1.04–9.09, p = 0.036), higher ESR level at reimplantation (OR, 1.85; CI, 1.05–3.57; p = 0.04), and time to reimplantation (OR, 1.00; CI, 1.003–1.005, p = 0.04). Performing revision arthroplasty surgery from 16 to 20 weeks had highest successful rate. The reimplantation over 24 weeks had a lower successful rate. However, no statistical significance in comparing each interval group. Conclusion Our study emphasized the importance of timely reimplantation in achieving successful outcomes. Factors such as ESR levels, spacer exchange, and the duration of time to reimplantation influenced the likelihood of treatment failure in two-stage exchange arthroplasty for hip and knee PJI.

Objectives: To report a large series where the full-thickness (FT) technique was applied and evaluate infectious and functional outcomes and compare these to the available literature. The ureteroneocystostomy technique of kidney transplantation has great variability. Kidney transplants performed at our institution use the FT technique as opposed to most centers. Ureteroneocystostomy performed without an anti-reflux mechanism (without tunneling) may increase the risk of acute renal graft pyelonephritis (AGPN) and thus compromise graft survival. Methods: Retrospective cohort study, based on 1275 medical records of kidney transplanted patients between 2007 and 2018. The outcomes were renal graft survival, ureteral complications, and occurrence of AGPN. Kaplan-Meier's analysis is used to describe estimated time averages and variability through the Log-Rank test. Poisson regression model is used to estimate multivariable prevalence ratios. Results: We found that renal graft survival rates were comparable to those found in the literature. The AGPN rate in our series was 12.53 episodes/100 patient-years, like other series in the literature. The ureteral complications rates are also similar. Our limitations were the impossibility to compare our results with a controlled group and the limited data underlying pathologies, rejection, and type of immunosuppression. Conclusions: The FT technique has survival outcomes and complications comparable to those of the Lich-Gregoir (LG) technique. The FT technique is simple and quicker to perform than LG and is a suitable alternative for ureteroneocystostomy for kidney transplant procedure.

The patient was 28-year-old male. He was suffered from chest pain at rest. He was diagnosed with AAORCA (anomalous aortic origin of the right coronary artery) by emergency catheter. Myocardial scintigraphy indicated ischemic changes in the right coronary artery region, so surgery was the plan. Reimplantation was selected because the coronary artery computed tomography showed little intramural travel and mild coronary artery stenosis. The surgery was performed under lower mini-sternotomy to facilitate early return to work. The patient had a good postoperative course, and was discharged from the hospital postoperative Day 11 after rehabilitation.

Background and Objectives: Robot-assisted extravesical ureteral reimplantation (REVUR) has been described as valuable alternative to open reimplantation in the pediatric population. This study aimed to report the outcome of REVUR in children with complex obstructed megaureter (COM) needing ureteral dismembering and/or tapering. Materials and Methods: The records of patients with COM, who received REVUR with ureteral dismembering and/or tapering over the last 3 years (2021–2024), were retrospectively reviewed. The inclusion criteria for COM included previous surgery, paraureteral diverticula, or ectopic megaureter. Results: A total of 16 patients (15 boys), with a median age of 7.8 years (range 2–16), were treated over the study period. COM was associated with paraureteral diverticula (n = 6), previous failed endoscopic balloon dilation (n = 4), ectopic megaureter (n = 2), and previous bulking agent endoscopic injection causing iatrogenic ureteral obstruction (n = 4). Presentation symptoms included febrile urinary tract infections (n = 8), flank pain (n = 4), hematuria (n = 2), and pseudo-incontinence (n = 2). All surgical procedures were accomplished robotically without conversions or intra-operative complications. Ureteral tapering was performed in 7/16 (43.7%). The median operative time (including robot docking) was 220 min (range 155–290). The median length of stay was 3.8 days (range 3–7). The indwelling double J stent was removed 4–6 weeks postoperatively. Clavien 2 grade complications occurred postoperatively in 2/16 (12.5%). At median follow-up of 34.5 months, all patients were asymptomatic and showed improved hydroureteronephrosis on ultrasound and improved drainage on diuretic renogram. Conclusions: This study demonstrates that robot-assisted extravesical ureteral reimplantation is a safe and effective treatment for primary obstructive megaureter and other complex ureteral anomalies in our patient cohort. The procedure showed low complication rates, high success rates, and favorable long-term outcomes, supporting the feasibility and effectiveness of robotic surgery for these conditions.

Introduction: Avulsion of teeth is one of the most complex forms of dental injury, and the selection of an appropriate storage medium greatly influences the preservation of Periodontal Ligament (PDL) cell viability, which is crucial for the successful re-implantation of avulsed teeth. Therefore, identifying effective storage options such as natural coconut water and prepackaged coconut water holds significant promise in improving outcomes for this challenging dental injury. Aim: To evaluate the efficacy of natural coconut water, prepackaged coconut water, and Hank's Balanced Salt Solution (HBSS) as storage media in maintaining PDL cell viability. Materials and Methods: A total of 32 non-carious freshly extracted human premolars were randomly divided into four study groups (n=8) and stored in the following storage media respectively: Group I-Natural coconut water group, Group IIPre-packaged coconut water group, Group III-Bench dry group, and Group IV-HBSS groups for 30 minutes. The PDL cells were collected and incubated in phosphate buffer saline for 30 minutes and then centrifuged at 800 rpm for five minutes. Following this, the cells were stained with trypan blue to observe their viability. The Analysis of Variance (ANOVA) with Tukey's post-hoc test was used for analysing the data. Results: The mean percentage of viable cells in natural coconut water (80.6250) was higher than in HBSS (79.8750), prepackaged coconut water (79.2500), and the bench dry group (6.1250). Meanwhile, the mean percentage of non-viable cells was highest in the bench dry group (93.8750), followed by the pre-packaged coconut water (20.7500), HBSS (20.1250), and natural coconut water (19.3750). Conclusion: Natural coconut water and pre-packaged coconut water are equally effective in maintaining the viability of PDL cells. Therefore, pre-packaged coconut water can be used as a substitute for natural coconut water for tooth storage, depending upon availability. [ABSTRACT FROM AUTHOR]

Purpose: To assess the prevalence and management of acquired cholesteatoma after cochlear implantation in pediatric and adult patients. Methods: Retrospective case review of pediatric and adult cochlear implants (CI) followed at a tertiary referral center and literature review of acquired cholesteatoma after CI surgery, to identify its prevalence, cause, and treatment. Results: Nine pediatric CIs were diagnosed with cholesteatoma in seven patients after 6.4 ± 4 years from CI surgery, and two adults after 11.3 and 21.7 years from CI surgery. Thirty-four pediatric cases and 26 adult cases are described in the literature. Cholesteatoma has a prevalence of 0.54% in pediatric CIs, and 1.79% in adult CIs (case series and literature). Adult cases were diagnosed significantly later compared to pediatric cases (Mann–Whitney test, p = 0.0460). Three pediatric cholesteatomas were treated with conservative surgery and preservation of the CI; they all developed recurrent disease. The remaining pediatric cases underwent subtotal petrosectomy with simultaneous CI explantation and staged reimplantation. Only one case recurred. The adult cases underwent simultaneous subtotal petrosectomy, explantation, and reimplantation. Similarly, 33.3% of cases treated with conservative/reconstructive surgery in the literature required revision surgery or conversion to subtotal petrosectomy against 6.2% of subtotal petrosectomies in the literature. Conclusions: Cholesteatoma after CI is a rare and late-onset complication of CIs. It is more prevalent in the adult CI population, although it affects children significantly earlier. The treatment of choice is subtotal petrosectomy and CI explantation with simultaneous or staged reimplantation. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To compare Frozen Section (FS) results during the reimplantation stage of revision knee arthroplasty, in patients without clinical signs of infection but with preoperative inconclusive serum inflammatory markers. METHODS: Sections were revisited the day after surgery. Intraoperative FS (iFS) was accepted as positive when the presence of >5 polymorphonuclear neutrophils (PMNLs) in 5 separate high-power fields was determined according to the consensus criteria of the International Consensus on Musculoskeletal Infection. The clinical outcomes, cultures and diagnostic values of iFS and review FS (rFS) were analyzed. RESULTS: No complications developed after reimplantation in 66 (84.6%) of the 78 evaluated patients. Complications developed in 12 patients, six of whom were treated with re-explantation, four with arthrodesis and two with above-the-knee amputation. Both iFS and rFS yielded insignificant sensitivity and specificity (25% and 45.5%, 25% and 45%, respectively). There was no statistically significant difference between definitive culture and iFS and rFS. CONCLUSION: iFS evaluation is insufficient to exclude recovery from periprosthetic joint infection (PJI). Diagnosis of recurrence of infection in patients with indefinite serum inflammatory markers between the explantation and reimplantation interval remains challenging due to massive fibrosis that makes proper tissue sampling difficult. The attending physician should closely monitor clinical findings. [ABSTRACT FROM AUTHOR]

An increasing number of young infants, as early as six months of age with congenital hearing loss receive cochlear implantation, and it is probable that many of these patients will require revision surgery later in life. The possibility of explantation of the cochlear electrode and reimplantation may cause damage to the cochlea, compromising the speech perception outcome in revision implant is of concern. There is only one prior temporal bone histopathology study to look at the outcome of revision surgery and no prior study evaluating revision cochlear implantation that used the round window approach. We conducted a histopathological study of four temporal bone specimens from four patients who underwent revision cochlear implantation and when available post-operative speech perception tests were evaluated. In all cases, the reimplanted electrode followed into the same fibrous sheath without evidence of additional intracochlear damage due to revision surgery. The intracochlear damage from the initial cochlear implantation appears to be a more important factor in outcomes rather than changes associated with explantation and reimplantation.

Objectives: To report a large series where the full-thickness (FT) technique was applied and evaluate infectious and functional outcomes and compare these to the available literature. The ureteroneocystostomy technique of kidney transplantation has great variability. Kidney transplants performed at our institution use the FT technique as opposed to most centers. Ureteroneocystostomy performed without an anti-reflux mechanism (without tunneling) may increase the risk of acute renal graft pyelonephritis (AGPN) and thus compromise graft survival. Methods: Retrospective cohort study, based on 1275 medical records of kidney transplanted patients between 2007 and 2018. The outcomes were renal graft survival, ureteral complications, and occurrence of AGPN. Kaplan-Meier's analysis is used to describe estimated time averages and variability through the Log-Rank test. Poisson regression model is used to estimate multivariable prevalence ratios. Results: We found that renal graft survival rates were comparable to those found in the literature. The AGPN rate in our series was 12.53 episodes/100 patient-years, like other series in the literature. The ureteral complications rates are also similar. Our limitations were the impossibility to compare our results with a controlled group and the limited data underlying pathologies, rejection, and type of immunosuppression. Conclusions: The FT technique has survival outcomes and complications comparable to those of the Lich-Gregoir (LG) technique. The FT technique is simple and quicker to perform than LG and is a suitable alternative for ureteroneocystostomy for kidney transplant procedure. [ABSTRACT FROM AUTHOR]

Introduction: A clinical case involving a 13-year-old boy with dental avulsion of his right upper central incisor and a concurrent soft tissue lesion on the lip is presented. The initial treatment involved lip suturing and reimplantation of the avulsed tooth, followed by splinting and bonding for a specified duration. Methods: Following the initial treatment, a control x-ray at the six-month mark revealed a radiolucent image at the tooth apex, prompting a decision to proceed with root canal treatment. Subsequently, after a period of nine years, the reimplanted tooth exhibited shortening and darkening, though its function remained unaffected. Results: Despite the observed changes in tooth appearance over the nine-year period, the functionality of the reimplanted tooth was not compromised. The treatment approach involving reimplantation and subsequent root canal treatment proved effective in preserving dental function and aesthetics. Conclusion: The findings suggest that reimplantation of a permanent tooth following avulsion can serve as an effective long-term treatment strategy. This approach not only preserves dental function and aesthetics but also delays the potential need for implant or prosthesis placement. Therefore, it should be considered as the primary therapeutic option in cases of dental avulsion, emphasizing its role in achieving favorable long-term outcomes. Update Dent.

Background: End-stage renal disease (ESRD) and renal transplant (RT) patients are known to have more perioperative and postoperative complications after arthroplasty surgeries when compared to patients without. We hypothesize that RT patients undergoing shoulder arthroplasty (SA) have fewer systemic and surgical complications when compared to ESRD patients undergoing SA. Methods: This was a retrospective review from the PearlDiver Patient Record Database. International Classification of Diseases and Current Procedural Terminology codes were used to identify patients who had undergone primary total and reverse shoulder arthroplasty, respectively, and subsequent surgical revisions. Unadjusted univariate analysis of patient demographics, Charlson Cormorbidty Index, and surgical complications at 90 days, 1 year, and 2 years after was performed using chi-squared testing. Multivariate logistic regression analyses were subsequently performed for systemic complications and prosthesis outcomes at all time points. Results: Of 1191 patients with ESRD or previous RT and who underwent either total shoulder arthroplasty or reverse total shoulder arthroplasty, 1042 (87.5%) had ESRD and 149 (12.5%) had a previous RT. ESRD SA patients were more likely to have hypertension, liver disease, coronary artery disease, and hypothyroidism. Interestingly no statistical significance was found in multivariate analysis for systemic complications at 90 days, nor for surgical complications at the 90-day, 1-year, or 2-year mark between ESRD and RT cohorts. Conclusion: SAs have comparable outcomes in ESRD and RT patients. The differing conclusions among studies might be partially accounted for by the demographic differences and comorbidities between these 2 patient populations. Providers should continue to provide appropriate counseling concerning risks, benefits, and timing of SA for these patients.

Abstract Background The present study describes the treatment of patients at a tertiary institution who experienced device failure after Cochlear Implantation (CI), as well as identifying prodromic symptoms that could assist in the timely identification and management of device failure. Study design Retrospective database review (January 2000–May 2017). Setting Single tertiary hospital. Methods Factors recorded included the etiology of hearing loss; age at first and revision CI surgeries; surgical information, including operation time and approach; electrical outcomes after implantation; device implanted; symptoms of device failure; history of head trauma; and audiologic outcomes as determined by categories of auditory performance (CAP). Results From January 2000 to May 2017, 1431 CIs were performed, with 27 (1.9%) undergoing revision surgeries due to device failure. The most common etiology of hearing loss was idiopathic (12/27), followed by cochlear hypoplasia (5/27). Mean age at initial CI was 11.8 (1–72) years, with 21 being pre-lingual and 6 being post-lingual. Of the total devices initially implanted, 80.5% were from Cochlear, 15.9% from MED-EL, and 3.5% from Advanced Bionics. The failure rates of these devices were 1.3%, 3.1%, and 10.0%, respectively. The most suggestive symptom of device failure was intermittent loss of signal. Mean CAP scores were 5.17 before reimplantation and 5.54 and 5.81 at 1- and 3-years, respectively, after reimplantation. Conclusion The most suggestive symptom preceding device failure was intermittent loss of signal. Patients who present with this symptom should undergo electrical examination for suspected device failure. Audiologic outcomes showed continuous development despite revision surgeries.

Abstract Background Valve-sparing aortic root replacement (VSARR) is a safe and effective surgical procedure to treat aortic root aneurysm. This meta-analysis aimed to investigate how this procedure might differ in patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV). Design Meta-analysis with meta-regression and systematic review. Setting Systematic search in the following databases: PubMed, Cochrane Central Register of Controlled Trials, and Embase. Interventions All observational studies of VSARR in patients with BAV or TAV were included in our study. Studies were included without any restrictions on language or publication date. A trial sequential analysis and a post-hoc meta-regression was performed on the main outcomes. Result Eleven articles met the inclusion criteria. A total of 1138 patients in BAV group, and 2125 patients in TAV group. No significant differences in gender and age were observed between BAV and TAV patients. BAV and TAV patients showed no differences in in-hospital mortality rate [0.00% vs. 1.93%; RR (95% CI) 0.33 (0.09, 1.26), I2 = 0%, P = 0.11] and the rate of in-hospital reoperation [5.64% vs. 5.99%; RR (95% CI) 1.01(0.59, 1.73), I2 = 33%, P = 0.98]. The overall long-term mortality rate of BAV patients was better than that of TAV patients [1.63% vs. 8.15%; RR (95% CI) 0.34 (0.13, 0.86), I2 = 0%, P = 0.02]. During the follow-up observation period, patients in TAV group showed small but no statistic advantage in 3-year, 5-year, and over 10-year incidences of reintervention. Regarding the secondary endpoints, the two groups showed similar aortic cross-clamping time and total cardiopulmonary bypass time. Conclusion The VSARR techniques yielded similar clinical outcomes in both BAV and TAV patients. Although patients with BAV might have a higher incidence of reinterventions after initial VSARR, it is still a safe and effective approach to treat aortic root dilation with or without aortic valve insufficiency. TAV patients showed small but no statistic advantage in long-term (over 10 years) reintervention rate, which means, patients with BAV may face a higher risk of reintervention in the clinic.

ObjectiveThe aim of this study is to summarize and demonstrate the different sterilization methods and surgical techniques for open fractures with impacted bone segments in the lower limbs.MethodsA retrospective analysis was conducted on the clinical characteristics, treatment methods, and outcomes of a case involving a 10.5 cm extruded segment of the femur in a 9-year-old male with a right femoral comminuted fracture treated at our center. Additionally, a retrospective review and summary were conducted on all reported cases of open fractures with impacted bone segments in the lower limbs.ResultsOur center treated a 9-year and 11-month-old male child who presented with a Gustilo type IIIB open fracture of the femur along with a large segment of the femur being ejected as a result of a car accident. The child was resuscitated to correct hypovolemic shock, underwent emergency wound debridement, and had Ilizarov external fixation of the femur. The ejected femur segment was sterilized using ethylene oxide and re-implanted four days after the injury. A literature review showed that out of the cases of open fractures with impacted bone segments in the lower limbs, there were 14 cases involving the femur and 5 cases involving the tibia. Among them, sterilization was performed using povidone-iodine in 6 cases, high-pressure steam sterilization in 3 cases, and other methods including gamma-ray irradiation and soaking in antibacterial solution were used in the remaining cases. In terms of surgical methods, 7 cases were fixed with locking plates, 3 cases were fixed with external fixation devices, 1 case was immobilized in a cast, 1 case was fixed with an intramedullary rod, and 4 cases involved a combination of external fixation and internal fixation. The average time for re-implantation was 7.6 days after the injury. There were no serious complications such as infection or non-union observed in any of the cases during follow-up.ConclusionEthylene oxide can be considered a reliable choice for the reimplantation of displaced bone segments in open fractures after sterilization.

Background: Giant middle cerebral artery (MCA) aneurysms are complex and challenging. Revascularization is frequently required in addition to trapping or clip reconstruction, and the MCA reimplantation bypass is ultimately needed when aneurysm excision is planned. Method: The operation was conducted in the hybrid operating suite, where an intraoperative cerebral angiography revealed a compromised MCA after multiple attempts of clip reconstruction. Therefore, we decided to perform an M2-M1 reimplantation bypass in conjunction with trapping and aneurysmectomy. Conclusion: Reimplantation bypass can be a rescue procedure for revascularization in complex aneurysms. The angioarchitecture varies among individuals; therefore, the optimal bypass technique should be tailored. [ABSTRACT FROM AUTHOR]

The diagnosis of persistent infection prior to second-stage reimplantation in 2-stage exchanges for periprosthetic joint infection (PJI) can be challenging as there is no optimal diagnostic tool. This study investigates the usefulness of pre-reimplantation serum C-reactive protein (CRP) and interleukin-6 (IL-6) and its change between both stages to identify patients who have subsequent PJI. There were 125 patients who underwent planned 2-stage exchange for chronic knee or hip PJI from a single center retrospectively identified. Patients were included if preoperative CRP and IL-6 were available for both stages. Subsequent PJI was defined as 2 positive microbiological cultures at reimplantation or subsequent surgery or death due to PJI during follow-up. Prior to reimplantation, the median serum CRP (total knee arthroplasties [TKAs]: 1.0 versus 0.5 mg/dL, P =.028; total hip arthroplasties [THAs]: 1.3 versus 0.5 mg/dL, P =.015) and median IL-6 (TKA: 8.0 versus 6.0 pg/mL, P =.052; THA: 7.0 versus 6.0 pg/mL, P =.239) were higher in patients who had subsequent PJI. The IL-6 and CRP values showed moderate sensitivity (TKA/CRP: 66.7%; THA/CRP: 58.8%; TKA/IL-6: 46.7%; THA/IL-6: 35.3%) and good specificity (TKA/CRP: 66.7%; THA/CRP: 81.0%; TKA/IL-6: 86.3%; THA/IL-6: 83.3%). The change in CRP and IL-6 between the stages did not differ between the groups, respectively. Serum CRP and IL-6 show low to moderate sensitivity and good specificity in the diagnosis of subsequent PJI prior to reimplantation, which questions their usefulness as a rule-out test. Furthermore, the change in between stages does not appear to identify subsequent PJI. [ABSTRACT FROM AUTHOR]

Despite progress in implantation technology and prophylactic measures, infection complications related to cardiac implantable electronic devices (CIED) are still a major concern with negative impacts on patient outcomes and the health system's resources. Infective endocarditis (IE) represents one of the most threatening CIED-related infections associated with high mortality rates and requires prompt diagnosis and management. Transvenous lead extraction (TLE), combined with prolonged antibiotic therapy, has been validated as an effective approach to treat patients with CIED-related IE. Though early complete removal is undoubtedly recommended for CIED-related IE or systemic infection, device reimplantation still represents a clinical challenge in these patients at high risk of reinfection, with many gaps in the current knowledge and international guidelines. Based on the available literature data and authors' experience, this review aims to address the practical and clinical considerations regarding CIED reimplantation following lead extraction for related IE, focusing on the reassessment of CIED indication, procedure timing, and the reimplanted CIED type and site. A tailored, multidisciplinary approach involving clinical cardiologists, electrophysiologists, cardiac imaging experts, cardiac surgeons, and infectious disease specialists is crucial to optimize these patients' management and clinical outcomes.

Purpose: To describe the clinical outcome of a series of seven eyes with an explanation of an original Glaucoma Drainage Device (GDD) arising from the complication of plate exposure and consequent reimplantation of another GDD at a second setting. Methods: This was a retrospective, interventional, and non-comparative study at two tertiary eye care hospitals in eastern and southern India. Electronic medical record data of the seven eyes where a GDD was explanted and a 2nd GDD was reimplanted over October 2010 and May 2021 was analyzed. Statistical analysis was done by SPSS (ver. 26). Results: The first GDD survived for a mean of 168 days only till the plate got exposed and thereby got explanted. Possible predisposing factors noted were conjunctival and scleral thinning, ischemic conjunctiva, etc., The reimplantation surgery was technically easy in the absence of hypotony--opposite to what is reported in the literature. The final IOP (mean +/- SD) values (mm Hg) were 18.9 (+/-7.9), range = 10-30. The mean number of glaucoma medications reduced from 3.9 (+/-1.2; range, 2 to 5) after the explanation to 3.1 (+/-0.7; range, 2 to 4) after the 2nd GDD implantation, in the final follow-up. The second GDD was found to be stable till the last follow-up (mean = 1149 days). No other significant intraoperative or postoperative complications were seen. Conclusions: Reimplantation of a second GDD in a separate setting after explanations of an original implant due to exposure-related complication is both a safe and effective method.

Total avulsion of the scalp is a serious traumatic injury and an absolute surgical emergency. Despite well-stocked literature on its immediate care, there is insufficient literature regarding its long-term complications. Here, we describe the case of a patient who developed chronic pain 24 months after replantation. The patient underwent several needle rigotomy sessions associated with lipofilling to reconstruct a sliding plane between the scalp and periosteum, followed by nanofat sessions to improve skin elasticity. This autologous fat injection treatment was successful, and the patient is currently pain-free. Therefore, lipofilling followed by nanofat injection is an effective treatment for this complication.

The bilateral duplex system is extremely uncommon, and only a few cases have been documented in the literature. It may manifest as a bifid renal pelvis and partial or complete ureteric duplication, with or without ectopic insertion of the ureter. An ectopic ureter is more problematic when there is significant vesicoureteral reflux, incontinence, and/or blockage. The optimal course of treatment is considered to be ureteral reimplantation rather than heminephrectomy. We describe the management strategy for a case of bilateral duplex kidneys with bilateral ectopic ureters in a growing female child. [ABSTRACT FROM AUTHOR]

Objectives: There is presently scarce literature describing the outcomes of patients undergoing robotic ureteral reconstruction (RUR) using the Boari flap (BF) technique. Herein, we report our prospective, multi-institutional experience using BF in patients undergoing robotic urinary reconstruction. Patients and Methods: We reviewed our prospective, multicenter database for all patients undergoing RUR between September 2013 and September 2021 in which a BF was utilized. Preoperative, perioperative, and follow-up data were collected and analyzed. Major complications were defined as a Clavien–Dindo classification grade >2. Surgical failure was defined as recurrent symptoms, obstruction on imaging, or the need for additional surgical interventions. Results: We identified 50 patients who underwent RUR using a BF. Four (8%) underwent the Single Port approach. Twenty-four patients (48%) were active or former tobacco users. Thirty-four patients (68%) had previously undergone abdominal surgery, 17 (34%) had prior ureteral stricture interventions, and 9 (18%) had prior abdominopelvic radiation. The most common stricture etiology was malignancy (34.4%). The median follow-up was 15.0 months with a 90% (45/50) success rate. The five documented cases of failure occurred at a median of 1.8 months following the procedure. Conclusion: In the largest prospective, multi-institutional study of patients undergoing RUR with BF in the literature to date, we demonstrate a low rate of complications and a high rate of surgical success in three tertiary academic medical centers. All observed failures occurred within 2 months of surgical intervention. [ABSTRACT FROM AUTHOR]

Accurate diagnosis of persistent periprosthetic joint infection (PJI) during 2-stage exchange remains a challenge. This study evaluated the diagnostic performance and thresholds of several commonly obtained serum and synovial markers to better guide reimplantation timing. This was a retrospective review of 249 patients who underwent 2-stage exchange with antibiotic spacers for PJI. Serum and synovial markers analyzed included white blood cell (WBC) count, polymorphonuclear percentage (PMN%), neutrophil-to-lymphocyte ratio (NLR), and absolute neutrophil count (ANC). Serum markers analyzed were erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), as well as percentage change in ESR and CRP from initial diagnosis to reimplantation. Area under the curve (AUC) analyses were performed to determine diagnostic accuracy of detecting PJI. In TKAs, synovial ANC and WBC had the highest AUCs (0.76), with thresholds of 2,952 and 3,800 cells/μL, respectively. The next best marker was serum CRP (0.73) with a threshold of 5.2 mg/dL. In THAs, serum CRP had the highest AUC (0.84) with a threshold of 4.3 mg/dL, followed by synovial PMN% (0.80) with a threshold of 77%. Percentage change in serum ESR or CRP provided low diagnostic value overall. Regarding serum markers, CRP consistently performed well in detecting persistent PJI in patients with antibiotic spacers. Absolute values of serum CRP and ESR had better diagnostic value than trends for guiding reimplantation timing. Diagnostic performance differed with joint type; however, synovial markers outperformed serum counterparts. No marker alone can be utilized to diagnose residual PJI in these patients, and further work is needed in this domain. [ABSTRACT FROM AUTHOR]

Electronic medical record data of the seven eyes where a GDD was explanted and a 2nd GDD was reimplanted over October 2010 and May 2021 was analyzed. Statistical analysis was done by SPSS (ver. 26). Results: The first GDD survived for a mean of 168 days only till the plate got exposed and thereby got explanted. Possible predisposing factors noted were conjunctival and scleral thinning, ischemic conjunctiva, etc., The reimplantation surgery was technically easy in the absence of hypotony—opposite to what is reported in the literature. The final IOP (mean +/− SD) values (mm Hg) were 18.9 (+/−7.9), range = 10–30. The mean number of glaucoma medications reduced from 3.9 (+/−1.2; range, 2 to 5) after the explanation to 3.1 (+/−0.7; range, 2 to 4) after the 2nd GDD implantation, in the final follow-up. The second GDD was found to be stable till the last follow-up (mean = 1149 days). No other significant intraoperative or postoperative complications were seen. Conclusions: Reimplantation of a second GDD in a separate setting after explanations of an original implant due to exposure-related complication is both a safe and effective method.
