Frequency and Distribution of Ophthalmic Surgical Procedures among Patients with Inherited Retinal Diseases

Objective or PurposeIn this study, we aimed to characterize the frequency and distribution of ocular surgeries in patients with inherited retinal diseases (IRDs) and evaluate associated patient and disease factors. DesignRetrospective cohort. ParticipantsSubjects 18 years and older who were followed at the Johns Hopkins Genetic Eye Disease (GEDi) Center. MethodsWe studied a retrospective cohort of patients with an IRD diagnosis to analyze the occurrence of laser and incisional surgeries. Subjects were categorized into two groups: central dysfunction (macular/cone/cone-rod dystrophy, "MCCRD group") and panretinal or peripheral dysfunction (retinitis pigmentosa-like, "RP group"). Genetic testing status was recorded. The association of patient and disease factors on the frequency, distribution, and timing of surgeries was analyzed. Main outcome MeasurePrevalence, prevalence odds ratio (POR), hazard ratio (HR) of ophthalmic procedures by phenotype. ResultsA total of 1472 eyes of 736 subjects were evaluated. Among them, 31.3% (n = 230) had undergone ocular surgery, and 78.3% of those (n=180/230) had a history of more than one surgery. A total of 602 surgical procedures were analyzed. Cataract extraction with intraocular lens implantation (CEIOL) was the most common (51.2%), followed by YAG capsulotomy, refractive surgery, retinal surgery, and others. CEIOL occurred more frequently in RP than in MCCRD subjects (POR 2.59, p = 0.002). RP subjects underwent CEIOL at a younger age than MCCRD patients (HR = 2.11, p < 0.001). ConclusionApproximately one-third of IRD patients had a history of laser or incisional surgery. CEIOL was the most common surgery; its frequency and timing may be associated with IRD phenotype. This data may inform the design of prospective research. Such efforts may illuminate routine clinical decision-making and contribute to surgical strategy development for cell and gene therapy delivery.

The Effect of Bimatoprost Implant on Glaucoma Patients: An Observational Study.

In this retrospective study of glaucoma patients receiving the bimatoprost implant at Duke Eye Center, the number of topical intraocular pressure-lowering medications was significantly reduced through 12 months after the implant. To study the effects of the bimatoprost implant on intraocular pressure (IOP) and the need for topical IOP-lowering medications in glaucoma patients in the clinical practice setting. Patients who received the bimatoprost implant at Duke Eye Center from November 2020 to October 2021 were identified. Exclusion criteria included addition of other IOP-lowering medications concurrent with the implant and <1 month of follow-up. The change in IOP and number of topical IOP-lowering medications from baseline to months 1, 3, 6, 9, and 12 after the implant was calculated. Subgroup analysis was performed for different glaucoma severities. A total of 63 patients and 92 eyes were included (mean age 77.8 ± 10.1 years). Glaucoma severity ranged from mild (11%), moderate (30%), to severe (54%). There was a nonsignificant decrease in IOP at all timepoints. The mean number of topical IOP-lowering medications significantly decreased by 0.81, 0.75, 0.63, 0.70, and 0.67 at month 1, 3, 6, 9, and 12, respectively (all P < 0.001). There was no significant change in the total number of medications, including the bimatoprost implant. When divided by glaucoma severity, the reduction in the number of topical medications was significant at 1, 3, and 6 months for mild/moderate disease and at 1 month for severe disease. During the follow-up period, 19 eyes underwent additional laser or surgical procedures, 68% of which had a history of prior incisional glaucoma surgery. The bimatoprost implant may reduce the need for topical IOP-lowering agents over a 1-year period, especially in mild to moderate-stage glaucoma. The efficacy of the implant may be more limited in severe glaucoma, and further work is needed to characterize its long-term effects.

A Comparison of Chemodnervation to Incisional Surgery for Acute, Acquired, Comitant Esotropia: An International Study

To compare the efficacy of botulinum toxin injections to strabismus surgery in children with acute, acquired, comitant esotropia (ACE), and to investigate factors predicting success. International, multi-center nonrandomized comparative study METHODS: Setting: Cloud-based survey. Children aged 2 to 17 years who underwent a single surgical intervention for ACE. Botulinum toxin injection ("chemodenervation" group) or strabismus surgery ("surgery" group). Primary measure: success rate at 6 months in propensity-matched cohort, defined as total horizontal deviation of 10 prism diopters or less with evidence of binocular single vision. Secondary measure: Risk factors for poor outcomes in the full cohort. Surgeons from 19 centers contributed. There were 74 patients in the chemodenervation group and 97 patients in the surgery group. In the propensity-matched data (n = 98), success rate was not significantly different at 6 months (70.2% vs 79.6%; P = .2) and 12 months (62.9% vs 77.8%; P = .2), but was significantly lower in the chemodenervation group at 24 months (52% vs 86.4%; P = .015). Irrespective of treatment modality, treatment delay was associated with lower success rates at 6 months, with median time from onset to intervention 4.5 months (interquartile range (IQR): 2.1, 6.7) in the success group and 7.7 months (IQR: 5.6, 10.1) in the failure group (P < .001). In children with ACE, success rate after chemodenervation was similar to that of surgery for up to 12 months but lower at 24 months. Those with prompt intervention and no amblyopia had the most favorable outcomes, regardless of treatment modality.

TRABECULECTOMY VERSUS TUBE OUTCOME IN NEOVASCULAR GLAUCOMA

Introduction: Neovascular glaucoma (NVG) is known to be a refractory form of glaucoma, which frequently requires the integrated use of medical, laser and incisional surgery. Tube-shunt implantation and trabeculectomy with anti-fibrotic agent are the two most-popular incisional procedures for managing refractory glaucoma. This study aims to compare surgical outcome between patients who underwent trabeculectomy versus tube-shunt implantation for the treatment of NVG. Methods: A retrospective study was held of NVG patients that underwent trabeculectomy and tube-shunt implantation between January 2020 - December 2022 at Dr. Kariadi Hospital, Semarang. IOP outcome and success rate was measured at 3 months post operatively. Statistical analysis was used to compare the outcome between groups, p&lt;0.05 was considered significant. Result: There were no significant differences in characteristics between groups at baseline. Mean IOP measured at 3 months postoperatively was 18.58 ± 5.53 and 15.94 ± 10.79 in trabeculectomy and tube group respectively (p=0.04), complete success rate was 18.8% in trabeculectomy and 25% in tube group, qualified success rate was 37.5% in trabeculectomy and 56.3% in tube group. Greater failure rate was observed in trabeculectomy group (43.8%). Conclusion: Compared to trabeculectomy, tube-shunt implantation has lower IOP at 3 months postoperatively in NVG. Similar number of anti-glaucoma medications was needed postoperatively in both procedure. Greater qualified success rate was achieved in tube-shunt implantation. Greater failure rate was observed in trabeculectomy.

Advancing geriatric surgical outcomes in elective ventral and incisional hernia repair surgeries: An American college of surgeons national surgical quality improvement program study

IntroductionIncreasing age is known to be associated with increased risk for postoperative morbidity and mortality, however, the goal of this study was to determine if an increase in age correlates to differences in surgical outcomes for elective ventral hernia repair. MethodsRetrospective cohort study using American College of Surgeons NSQIP database from 2016 to 2020. Included diagnosis codes were laparoscopic or open incisional or ventral hernia repairs, categorized into three age groups: 18-64y, 65-74y, and ≥75y. Thirty-day perioperative outcomes analyzed using bivariate χ2 test and multivariate logistic regression. ResultsWe identified 116,643 people who had elective ventral or incisional hernia repair. Compared to 18-64y and 65-74y age groups, patients ≥75y were significantly more likely to develop any post-operative complication, be re-admitted post-operatively for any reason, have an extended hospital stay, and require a reoperation. ConclusionsPatients ≥75y have significantly higher rates of perioperative complications after elective hernia repair compared to younger patients.

Outcomes of Eyes Lost to Follow-up After Treatment With Intraocular or Periocular Steroid Injections.

Purpose: To evaluate the visual, intraocular pressure (IOP), and anatomic outcomes of eyes with loss to follow-up (LTFU) after intravitreal or periocular steroid injections. Methods: Patients receiving intraocular or periocular steroid injections and with LTFU for at least 180 days were included in this retrospective cohort study. Charts were reviewed for the visual acuity (VA), IOP, and central foveal thickness at the visit before LTFU, the first return visit, and 3, 6, and 12 months after return. Results: Fifty-three eyes of 47 patients were identified. The mean (±SD) age was 62.3 ± 14.9 years, the mean LTFU time was 295 ± 181.2 days (range, 182-1101), and the mean follow-up after return was 354 ± 339.3 days (range, 32-1141). The overall mean number of steroid injections was 5.2 ± 3.9 (range, 1-18). Compared with the mean logMAR VA at the visit before LTFU (0.59 [Snellen 20/77]), the mean VA remained stable at all timepoints after return as follows: return visit (0.62 [20/83]; P = .6), month 3 (0.55 [20/70]; P = .6), month 6 (0.55 [20/70]; P = .5), month 12 (0.64 [20/87]; P = .6), and final visit (0.69 [20/97]; P = .2). At the first return visit, 8 (15%) of 53 patients had an IOP of 21 mm Hg or higher (range, 21-31); 2 required treatment with a new antihypertensive medication (latanoprost and timolol, respectively). Conclusions: Patients with LTFU after receiving steroid injections maintained their VA. No patient required incisional glaucoma surgery. Compared with other etiologies, eyes with diabetic macular edema had a greater increase in IOP.

Aqueous Shunts with Extraocular Reservoir for Open-Angle Adult Glaucoma: A Report by the American Academy of Ophthalmology

To evaluate the recently published literature on the efficacy and safety of the use of aqueous shunts with extraocular reservoir for the management of adult open-angle glaucomas (OAGs). A search of peer-reviewed literature was last conducted in April 2023 of the PubMed database and included only articles published since the last aqueous shunt Ophthalmic Technology Assessment, which assessed articles published before 2008. The abstracts of these 419 articles were examined, and 58 studies were selected for full-text analysis. After inclusion and exclusion criteria were applied, 28 articles were selected and assigned ratings by the panel methodologist according to the level of evidence. Twenty-five articles were rated level I and 3 articles were rated level II. There were no level III articles. Implantation of aqueous shunts with extraocular reservoir can lower intraocular pressure (IOP) by between one-third and one-half of baseline IOP, depending on whether it is undertaken as the primary or secondary glaucoma surgery. Success rates for aqueous shunts were found to be better than for trabeculectomies in eyes with prior incisional surgery. Conversely, in eyes without prior incisional surgery, implantation of aqueous shunts was found to have an overall lower success rate as the primary glaucoma procedure compared with trabeculectomy. Although both valved and nonvalved aqueous shunts with extraocular reservoir were effective, the nonvalved device generally achieved slightly lower long-term IOPs with fewer glaucoma medications and less need for additional glaucoma surgery. Both devices slow the rates of visual field progression with efficacy comparable with that of trabeculectomy. Early aqueous humor suppression after aqueous shunt implantation is recommended for the management of the postoperative hypertensive phase and long-term IOP control. No strong evidence supports the routine use of mitomycin C with aqueous shunt implantation for OAG. Implantation of aqueous shunts with extraocular reservoir, including valved or nonvalved devices, has been shown to be an effective strategy to lower IOP. Strong level I evidence supports the use of aqueous shunts with extraocular reservoir by clinicians for the management of adult OAG.

Scheimpflug Corneal Tomography Anterior Chamber Depth in Descemet Stripping Endothelial Keratoplasty Recipients.

Our study investigates whether preoperative anterior chamber depth (ACD) measured by Scheimpflug tomography could serve as a potential predictor of graft failure in eyes undergoing Descemet stripping endothelial keratoplasty (DSEK). A retrospective review was conducted on patients who underwent primary or repeat DSEK between January 2020 and August 2021 at Bascom Palmer Eye Institute. Charts from 378 primary and 192 repeat DSEK patients were reviewed and ultimately 47 primary and 21 repeat DSEK patients met criteria for inclusion. Data collection included demographics, preoperative ACD, best-corrected visual acuity, and length of follow-up. Demographics were similar between groups, and there was no significant difference in the average best-corrected visual acuity between the single and repeat DSEK groups preoperatively. Baseline preoperative ACD was greatest in the single DSEK group (3.51 ± 0.90 mm) when compared to baseline preoperative ACD in the repeat DSEK group (3.01 ± 0.67 mm, P = 0.003). The preoperative mean ACD was smallest in the repeat DSEK group before the second DSEK (2.94 ± 0.48 mm, P = 0.001). Preoperative baseline ACD was the only variable to affect graft survival time significantly ( P = 0.012). The incidence of glaucoma diagnosis was similar in both groups (42.5% vs. 42.8%, P = 0.471). The diagnosis of glaucoma and presence of incisional glaucoma surgery did not affect the graft survival time ( P = 0.129, P = 0.559) or need for repeat DSEK. Smaller baseline preoperative Scheimpflug ACD measurement may be a possible predictor of the need for repeat DSEK. Our study found that Scheimpflug ACD decreases with subsequent DSEK failure.

Effect of bimatoprost sustained-release intracameral implant on intraocular pressure and medication burden in patients with prior glaucoma surgery

The present retrospective study evaluated intraocular pressure (IOP) and medication burden after bimatoprost sustained-release (bimatoprost SR, Durysta, Allergan) implantation in patients with glaucoma. A secondary objective was to examine an effect of bimatoprost SR in a subset of patients with prior minimally invasive and incisional glaucoma surgery. A retrospective chart review of 122 eyes that received bimatoprost SR by 6 glaucoma specialists at Wills Eye Hospital between March 2020 and September 2021 was performed. One hundred and eighteen eyes from 84 patients had a reduction in IOP (18.5±5.7mmHg vs. 16.0±5.4mmHg, P<0.01) and required fewer glaucoma medications (2.1±1.4 vs. 1.2±1.2, P<0.01) after bimatoprost SR implantation. In 41 eyes from 31 patients who previously underwent glaucoma surgery (including iStent, goniotomy, trabeculectomy, Xen Gel Stent, or tube shunt surgery), medication burden was decreased after bimatoprost SR implantation (1.9±1.3 vs. 1.0±1.0, P<0.001). These data suggest that bimatoprost SR is an efficacious treatment modality for glaucoma, even in post-surgical patients.

Effects of Modulated Transcutaneous Electrical Nerve Stimulation on Incisional Pain Post Cardiac Surgery. A Randomized Controlled Trial

Purpose: To evaluate effects of modulated transcutaneous nerve stimulation on incisional pain post cardiac surgery. Methods/design: 40 patients undergoing cardiac surgery were randomized into 2 groups (20 in each) by single blinded envelope sealed method. Experimental group has been given Modulated TENS following normal cardiac rehabilitation while Control Group has been given Placebo TENS Following normal cardiac rehabilitation respectively. TENS was given for 30 minutes once in a day after the removal of pacing wire till the day of discharge. Pre intervention outcome measure for pain (VAS) and Anxiety (BAI) was evaluated on the first and last day of the treatment. Results: Between the group analysis is done using Mann Whitney U Test. The results showed there is significant difference between the groups in pre and post values VAS, where as for BAI there is no significant difference between the groups in pre and post values. Within the group analysis was done by Wilcoxon Sign Rank Test. The results indicated a significant difference in the pre and post values of VAS and BAI. Conclusion: From the study conducted, we came to a conclusion that transcutaneous electrical nerve stimulation was found to be effective in reducing incisional pain post cardiac surgery.

Incisional hernia repair following pancreatic surgery—open vs laparoscopic approach

IntroductionFor pancreatic procedures, transverse and midline or combined approaches are used. Having an increased morbidity after pancreatic surgery, these patients have an increased risk of developing an incisional hernia. In the following, we will analyze how the results of incisional hernia surgery after pancreatic surgery are presented in the Herniamed Registry.MethodsHospitals and surgeons from Germany, Austria and Switzerland can voluntarily enter all routinely performed hernia operations prospectively into the Herniamed Registry. All patients sign a special informed consent declaration that they agree to the documentation of their treatment in the Herniamed Registry. Perioperative complications (intraoperative complications, postoperative complications, complication-related reoperations and general complications) are recorded up to 30 days after surgery. After 1, 5, and 10 years, patients and primary care physicians are contacted and asked about any pain at rest, pain on exertion, chronic pain requiring treatment or recurrence. This retrospective analysis of prospectively collected data compares the outcomes of minimally invasive vs open techniques in incisional hernia repair after pancreatic surgery.ResultsRelative to the total number of all incisional hernia patients in the Herniamed Registry, the proportion after pancreatic surgery with 1-year follow-up was 0.64% (n = 461) patients. 95% of previous pancreatic surgeries were open. Minimally invasive incisional hernia repair was performed in 17.1% and open repair in 82.9% of cases. 23.2% of the defects were larger than 10 cm and 32.8% were located laterally or were a combination of lateral and medial defects. Among the few differences between the collectives, a significantly higher rate of defect closure (58.1% vs 25.3%; p < 0.001) and drainage (72.8% vs 13.9%; p < 0.001) was found in the open repairs, and larger meshes were seen in the minimally invasive procedures (340.6 cm2 vs 259.6 cm2; p < 0.001). No difference deemed a risk factor for chronic postoperative pain was seen in the rate of preoperative pain between the open and minimally invasive procedures (Appendix Table 4) No significant differences were found in either the perioperative complications or at 1-year follow-up.ConclusionsIncisional hernias after complex pancreatic surgery can be repaired safely and with a low recurrence rate in both open and minimally invasive techniques.

Addressing Glaucoma in Myopic Eyes: Diagnostic and Surgical Challenges.

Epidemiological and genetic studies provide strong evidence supporting an association between myopia and glaucoma. The accurate detection of glaucoma in myopic eyes, especially those with high myopia, remains clinically challenging due to characteristic morphologic features of the myopic optic nerve in addition to limitations of current optic nerve imaging modalities. Distinguishing glaucoma from myopia is further complicated by overlapping perimetric findings. Therefore, longitudinal follow-up is essential to differentiate progressive structural and functional abnormalities indicative of glaucoma from defects that may result from myopia alone. Highly myopic eyes are at increased risk of complications from traditional incisional glaucoma surgery and may benefit from newer microinvasive glaucoma surgeries in select cases.

Access to Eye Care Providers and Glaucoma Severity in the National Institutes of Health All of Us Research Program.

In the "All of Us (AoU) Research Program," individuals with access to vision care were more likely to have mild, moderate, or severe glaucoma and undergo incisional surgery compared with those without vision care access. To examine the associations between access to eye care, glaucoma severity, and incisional glaucoma surgery using data from the National Institute of Health AoU Research Program. Individuals with International Classification of Diseases Ninth or 10th Revision codes and who answered the survey question about eye care access in AoU were included in the study. The exposure variable was access to eye care services, with outcome variables (1) glaucoma severitys and (2) likelihood of incisional surgery. Unadjusted multinomial logistic regression compared access to eye care services and glaucoma severity. In addition, unadjusted logistic regression models compared access to eye care and the likelihood of incisional surgery. These were repeated using adjusted analyses, controlling for sex assigned at birth, race and ethnicity, and age. Compared with individuals without access to eye care services, those with access were more likely to have all levels of glaucoma severity [mild adjusted odds ratio (aOR): 5.81, 95% CI: 3.15-10.73, moderate aOR: 4.44, 95% CI: 2.45-8.02, severe aOR: 6.95, 95% CI: 2.69-17.93, and unspecified aOR: 3.06, 95% CI: 2.72, 3.45]. Access to eye care was associated with increased odds of any incisional glaucoma surgery (aOR: 3.00, 95% CI: 1.24-9.90) and of trabeculectomy (aOR: 3.30, 95% CI: 1.02-20.28) but not of tube shunt procedures (aOR: 2.65, 95% CI: 0.80-16.38). This study demonstrated that access to eye care services was associated with a higher prevalence of all levels of glaucoma severity; those with access to eye care services were more likely to undergo incisional surgery than those without access. Future research should focus on methods to best encourage eye care to limit glaucoma progression.

Outcome of incisional hernia repair in patients 80 years and older: results from the Herniamed-Registry

IntroductionMore and more often complex abdominal surgeries are performed in the elderly. Together with the ageing population these patients are at risk for incisional hernias. We aimed on assessing outcomes following incisional hernia surgery in patients 80 years and older.Material and methodsUsing the Herniamed-Registry, a prospective multi-institutional database, data on patients undergoing surgery for incisional hernias were retrospectively assessed. 46,040 patients were included and divided by age. Intraoperative-, general-, and postoperative complications as well as 1-year follow-up outcomes were assessed and compared between patients 80 years and older vs younger than 80 years.ResultsIntra- (2.3% vs 1.5%; p < 0.001) and postoperative (8.6% vs 7.2%; p = 0.001) complications, general complications (5.5% vs 3.0%; p < 0.001), as well as reoperations (3.8% vs 3.0%; p = 0.007) were more likely to occur in elderly patients. By contrast, recurrences (3.6% vs 4.5%; p = 0.007), pain at rest (7.3% vs 10.1%; p < 0.001) and on exertion (11.3% vs 18.3%; p < 0.001), as well as pain requiring treatment (5.4% vs 7.7%; p < 0.001) was less likely in the group of patients aged ≥ 80 years.ConclusionIncisional hernia repair in patients 80 years and older is associated with a slightly higher complication risk but is quite acceptable and also have improved pain scores. The recurrence difference is also clinically unimportant.

Isotretinoin Use in Transmasculine Patients and Its Implication on Chest Masculinization Surgery: Scoping Review of the Literature.

Acne often worsens in transmasculine patients who are on prolonged testosterone therapy. Isotretinoin is an oral retinoid used in the treatment of severe or refractory cases of acne, but it has the potential to cause delayed wound healing. Transmasculine patients may potentially be prescribed treatment for acne with isotretinoin while also planning to undergo chest masculinization surgery. This scoping review aims to determine whether isotretinoin has a negative impact on postoperative healing in transmasculine patients undergoing chest masculinization surgery. A scoping review was performed using the PubMed and Ovid databases. A total of 16 publications were selected for inclusion. Acne tends to peak in transmasculine patients 6 months after initiation of testosterone treatment. Severe cases can be treated with isotretinoin; however, acne may recur once treatment is discontinued, given ongoing hormone therapy. There is little to no evidence in the medical literature regarding perioperative use of isotretinoin specifically among transmasculine patients undergoing chest masculinization surgery. In general, however, recent studies have found no evidence of increased hypertrophic scars or keloids in patients taking isotretinoin. Further studies are required to strengthen the current evidence that suggests that isotretinoin does not need to be discontinued before or after incisional or excisional surgeries, including chest masculinization surgery in transmasculine patients.

Outcomes of recurrent incisional hernia repair by open and laparoscopic approaches: a propensity score-matched comparison.

Recurrent incisional hernias are challenging, and their surgical outcomes have not been well studied. We aimed to analyze the outcomes of recurrent incisional hernia repair in a propensity score-matched cohort study on laparoscopic intra-peritoneal onlay mesh repair (lap. IPOM) versus open sublay repair. All consecutive patients who had undergone open sublay repair and lap. IPOM of recurrent incisional hernia between January 2015 and December 2021 at a tertiary hernia center was identified. One-to-one propensity score matching was used to achieve a balanced exposure groups at baseline. Of 255 patients, 85/95 with open sublay repair were matched to 85/160 with lap. IPOM. Before matching, the open sublay group had significantly larger hernia defects (6.3cm vs. 5.0cm) than the lap. IPOM group. Other major baseline imbalances were also found in body mass index (BMI), obesity and European Hernia Society (EHS) width classification. The pre-match results showed that the lap. IPOM group had significantly shorter operative time (median 75 vs. 95min) and shorter postoperative hospital stay (median 8 vs. 11days) compared with the open sublay group. Wound infection (8.4% vs. 1.9%) and hematoma (5.3% vs. 0.6%) occurred more frequently after open sublay repair. After matching, baseline characteristics were well balanced. The recurrence rate and incidence of complications were comparable between the two groups. However, the post-match analysis still showed that lap. IPOM was associated with decreased length of postoperative stay. The outcomes of recurrent incisional hernia surgery after lap. IPOM and open sublay repair appear similar, except that the former had shorter length of postoperative stay. However, the poor outcomes were more likely associated with the unfavorable risk profiles, such as larger defect size, rather than the procedure technique itself.

Case report of unusual complication following thread lifting: an obstructive stone in the parotid duct

Advances in plastic surgery have included a shift toward less invasive procedures. To improve outcomes and avoid incisional surgery, numerous noninvasive face-lifting techniques have been studied. This includes thread-lifting, a technique that promises to correct facial aging with limited scarring, rapid recovery, and minimal complications. As the population ages, an increasing number of ordinary people in South Korea are undergoing thread lifting procedures for the purpose of rejuvenation. The procedure involves insertion of a thread under the skin into the subcutaneous tissue, using a long needle as a guide. Dents or barbs prevent the thread from slipping and provide uniform aggregation of soft tissue to create a new volume contour when the thread is lifted. This procedure has gained worldwide popularity and is frequently performed. However, some minor complications have been reported. In this paper, we report an unusual complication: an obstructive stone in the parotid (Stensen) duct after a thread-lifting procedure using nonabsorbable anchoring threads.

Suture Fixation to Reduce Graft Detachment in Descemet Stripping Endothelial Keratoplasty.

The aim of this study was to report the outcomes of graft fixation using interrupted, full-thickness sutures on graft detachment after Descemet stripping endothelial keratoplasty (DSEK). All DSEK procedures performed at Mayo Clinic, Rochester, MN, from 2015 through 2022 were retrospectively reviewed. Risk factors for graft detachment were defined as previous incisional glaucoma surgery, previous penetrating keratoplasty, or absence of the normal lens-capsule barrier. Cases were categorized into sutured, high-risk grafts; unsutured, high-risk grafts; and unsutured, low-risk grafts. The primary outcome was graft detachment, and secondary outcomes were early graft failure and graft clarity at 12 months after surgery. Demographics between the high-risk groups were similar for sex and age at the time of surgery. Graft detachment occurred in 4 of 97 sutured, high-risk eyes (4.1%) and 24 of 119 unsutured high-risk eyes (20.2%) ( P = 0.002). In comparison, graft detachment occurred in 18 of 181 unsutured low-risk eyes (9.9%). The incidence of early graft failure was 2.1%, 5.0%, and 3.3% and late graft failure by 12 months was 9.8%, 12.8%, and 4.2%, respectively. In eyes with high-risk factors for graft detachment, suture fixation of the graft in DSEK decreased graft detachment to a rate at least as low as that in low-risk eyes.

Evaluation of rectus abdominis muscle strength and width of hernia defect in patients undergoing incisional hernia surgery.

The aim of this study was to analyze the strength status of the rectus abdominis muscle in patients with incisional hernia and the relationship between the width of the hernia defect and the strength of the rectus abdominis muscle. This is a observational cohort study of patients with medial line incisional hernia (July-October 2022), classified as W2 according to the European Hernia Society (EHS). The data collected were demographic and clinical characteristics related to hernia, and measure of the rectus abdominis muscle strength using an isokinetic dynamometer and a strain gauge. We analyzed the relationship between hernia width and rectus abdominis muscle strength with correlation tests to adjustment by age, sex, BMI, and body composition. A total of 40 patients (64% female) with a mean age of 57.62years (SD 11) were enrolled in the study. The mean BMI was 29.18 (SD 5.06), with a mean percentage of fat mass of 37.8% (SD 8.47) and a mean percentage of muscle mass of 60.33% (SD 6.43). The maximum width of the hernia defect was 6.59cm (SD 1.54). In the male group, the mean bending force moment (ISOK_PT) was 94.01Nwm (SD 34.58), bending force moment relative to body weight (ISOK_PT_Weight) was 103.32Nwm (SD 37.48), and peak force (PK_90) was 184.71 N (SD 47.01). In the female group, these values were 58.11Nwm (SD 29.41), 66.48Nwm (SD 32.44), and 152.50 N (SD 48.49), respectively. Statistically significant differences were observed in the relationship between the data obtained with the isokinetic dynamometer and sex (p = 0.002), as well as between the data obtained with the isokinetic dynamometer and age (p = 0.006). Patients in the 90th percentile (P90) of rectus abdominis muscle strength also had smaller hernia defect widths (p = 0.048). In this study, age and sex were identified as the most statistically significant predictor variables for rectus abdominis muscle strength. The width of the hernia defect exhibited a trend towards statistical significance.
