In Vitro and Randomized Controlled Clinical Study of Natural Constituents' Anti-HPV Potential for Treatment of Plantar Warts Supported with In Silico Studies and Network Analysis.

The aim of this study is to evaluate the anti-HPV potential of a Moringa olifera Lam seed, Nigella sativa L. seed, and Musa Acuminata peel herbal mixture in the form of polymer film-forming systems. A clinical trial conducted in outpatient clinics showed that the most significant outcome was wart size and quantity. Compared to the placebo group, the intervention group's size and number of warts were considerably better according to the results. Chemical profiling assisted by LC-HRMS led to the dereplication of 49 metabolites. Furthermore, network pharmacology was established for the mixture of three plants; each plant was studied separately to find out the annotated target genes, and then, we combined all annotated genes of all plants and filtered the genes to specify the genes related to human papilloma virus. In a backward step, the 24 configured genes related to HPV were used to specify only 30 compounds involved in HPV infection based on target genes. CA2 and EGFR were the top identified genes with 16 and 12 edges followed by PTGS2, CA9, and MMP9 genes with 11 edges each. A molecular docking study for the top active identified compounds of each species was conducted in the top target HPV genes, CA2 and EGFR, to investigate the mode of interaction between these compounds and the targets' active sites.

Review of Dohan Eherenfest et al. (2009) on "Classification of platelet concentrates: From pure platelet-rich plasma (P-PRP) to leucocyte- and platelet-rich fibrin (L-PRF)".

This classic discusses the original publication of Dohan Eherenfest et al. on "Classification of platelet concentrates: from pure platelet-rich plasma (P-PRP) to leucocyte- and platelet-rich fibrin (L-PRF)", in which the authors propose four categories of platelet concentrates depending on their leucocyte and fibrin content (P-PRP, leucocyte- and platelet-rich plasma (L-PRP), pure platelet-rich fibrin (P-PRF), and L-PRF) to group a "jungle" of products in which the term platelet-rich plasma (PRP) was used indistinctly. They were able to identify common factors such as: (1) the use of anticoagulants and immediate centrifugation of the blood after its collection; (2) most preparation techniques allowed platelet concentrate preparation within an hour; (3) the centrifugation aimed to separate the blood in layers that would allow the extraction of specific fractions; and (4) the product was activated with thrombin or calcium chloride. The reviewed manuscript has been listed among the most cited PRP articles in regenerative medicine, with more than 800 citations, driving current scientific research and clinical practise by categorising L-PRP and P-PRP (now, leucocyte-poor PRP). The classification has also opened the door to understanding intrinsic biological mechanisms between platelets, leukocytes, fibrin, and growth factors, which will later be considered for studying the proliferation and differentiation of cells in different tissues affected by PRP. Since the initial classification of platelet concentrates, several other classification systems have been proposed and published in the current literature such as platelet, activation, white blood cell (PAW), Mishra, platelet, leucocyte, red blood cells, and activation (PLRA), dose of platelet, efficiency, purity, and activation (DEPA), method, activation, red blood cells, spin, platelets, image guidance, leukocytes, and light activation (MARSPILL), etc. These classifications have identified important aspects of PRP that affect the biological composition and, ultimately, the indications and outcomes. To date, there is still a lack of standardisation in sample preparation, cohort heterogeneity, and incomplete reporting of sample preparation utilised, leading to a lack of clarity and challenging researchers and clinicians.

A meta-analysis evaluating wound infections and other complications following distal versus complete gastrectomy for gastric cancer.

A meta-analysis investigation was carried out to measure the wound infections (WIs) and other postoperative problems (PPs) of distal gastrectomy (DG) compared with total gastrectomy (TG) for gastric cancer (GC). A comprehensive literature investigation till February 2023 was used and 1247 interrelated investigations were reviewed. The 12 chosen investigations enclosed 2896 individuals with GC in the chosen investigations' starting point, 1375 of them were TG, and 1521 were DG. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were utilized to compute the value of the WIs and other PPs of DG compared with TG for GC by the dichotomous approaches and a fixed or random model. TG had significantly higher overall PP (OR, 1.58; 95% CI, 1.15-2.18, p = 0.005), WIs (OR, 1.69; 95% CI, 1.07-2.67, p = 0.02), peritoneal abscess (PA) (OR, 2.99; 95% CI, 1.67-5.36, p < 0.001), anastomotic leakage (AL) (OR, 1.90; 95% CI, 1.21-2.97, p = 0.005) and death (OR, 2.26; 95% CI, 1.17-4.37, p = 0.02) compared to those with DG in individuals with GC. TG had significantly higher overall PP, WIs, PA, AL and death compared to those with DG in individuals with GC. However, care must be exercised when dealing with its values because of the low sample size of some of the nominated investigations for the meta-analysis.

Prevalence of surgical site wound infection after spine surgery in nasal colonization of methicillin-resistant Staphylococcus aureus: A meta-analysis.

The purpose of the meta-analysis was to evaluate and compare the prevalence of surgical site infection (SSI) after spine surgery (SS) in nasal colonization of methicillin-resistant Staphylococcus aureus (MRSA). The results of this meta-analysis were analysed, and the odds ratio (OR) and mean difference (MD) with 95% confidence intervals (CIs) were calculated using dichotomous or contentious random- or fixed-effect models. For the current meta-analysis, 14 examinations spanning from 2014 to 2022 were included, encompassing 18 410 people who were tested for nasal colonization after SS. MRSA-positive had a significantly higher SSI (OR, 3.65; 95% CI, 2.48-5.37, p < 0.001) compared with MRSA-negative in SS subjects. However, no significant difference was found between methicillin-susceptible Staphylococcus aureus and Staphylococcus aureus negative (OR, 0.94; 95% CI, 0.32-2.79, p = 0.91), and Staphylococcus aureus positive and negative (OR, 2.13; 95% CI, 0.26-17.41, p = 0.48) in SS subjects. The examined data revealed that MRSA colonization had a significant effect on SSI; however, methicillin-susceptible Staphylococcus aureus and Staphylococcus aureus had no significant effect on SSI in SS subjects. However, given that some comparisons included a small number of chosen studies, attention should be given to their values.

Effect of hyperbaric oxygen treatment on diabetic foot ulcers: A meta-analysis.

The meta-analysis aimed to assess the effect of hyperbaric oxygen treatment on diabetic foot ulcers. Using dichotomous or contentious random or fixed effect models, the outcomes of this meta-analysis were examined and the odds ratio (OR) and the mean difference (MD) with 95% confidence intervals (CIs) were computed. 17 examinations from 1992 to 2022 were enrolled for the present meta-analysis, including 7219 people with diabetic foot ulcers. Hyperbaric oxygen treatment had a significantly higher healed ulcer (OR, 14.39; 95% CI, 4.02-51.52, p < 0.001), higher adverse event (OR, 2.14; 95% CI, 1.11-4.11, p = 0.02), lower mortality (OR, 0.22; 95% CI, 0.07-0.71, p = 0.01) and higher ulcer area reduction (MD, 23.39; 95% CI, 11.79-34.99, p < 0.001) compared to standard treatment in patients with diabetic foot ulcers. However, hyperbaric oxygen treatment and standard treatment had no significant difference in amputation (OR, 0.62; 95% CI, 0.22-1.75, p = 0.37), major amputation (OR, 0.59; 95% CI, 0.18-1.92, p = 0.38), minor amputation (OR, 0.64; 95% CI, 0.15-2.66, p = 0.54) and healing time (MD, -0.001; 95% CI, -0.76 to 0.75, p = 0.99) in patients with diabetic foot ulcers. The examined data revealed that hyperbaric oxygen treatment had a significantly higher healed ulcer, adverse event, and ulcer area reduction and lower mortality, however, there was no significant difference in amputation and healing time compared to standard treatment in patients with diabetic foot ulcers. Yet, attention should be paid to its values since most of the selected examinations had a low sample size and some of the comparisons had a low number of selected studies.

Higher sensitive selective spectrofluorometric determination of ritonavir in the presence of nirmatrelvir: application to new FDA approved co-packaged COVID-19 pharmaceutical dosage and spiked human plasma.

BACKGROUND: Ritonavir was recently combined with nirmatrelvir in a new approved co-packaged medication form for the treatment of COVID-19. Quantitative analysis based on fluorescence spectroscopy measurement was extensively used for sensitive determination of compounds exhibited unique fluorescence features. OBJECTIVE: The main objective of this work was to develop higher sensitive cost effective spectrofluorometric method for selective determination of ritonavir in the presence of nirmatrelvir in pure form, pharmaceutical tablet as well as in spiked human plasma. METHODS: Ritonavir was found to exhibit unique native emission fluorescence at 404 nm when excited at 326 nm. On the other hand, nirmatrelvir had no emission bands when excited at 326 nm. This feature allowed selective determination of ritonavir without any interference from nirmatrelvir. The variables affecting fluorescence intensity of ritonavir were optimized in terms of sensitivity parameters and principles of green analytical chemistry. Ethanol was used a green solvent which provided efficient fluorescence intensity of the cited drug. RESULTS: The method was validated in accordance with the ICH Q2 (R1) standards in terms of linearity, limit of detection (LOD), limit of quantification (LOQ), accuracy, precision and specificity. The described method was successfully applied for ritonavir assay over the concentration range of 2.0-20.0 ng/mL. CONCLUSION: Ritonavir determination in the spiked human plasma was successfully done with satisfactory accepted results.

Efficiency of platelet-rich plasma in the management of burn wounds: A meta-analysis.

The meta-analysis aimed to assess the efficiency of platelet-rich plasma (PRP) in the management of burn wounds (BWs). Using dichotomous or contentious random- or fixed-effects models, the outcomes of this meta-analysis were examined and the odds ratio (OR) and the mean difference (MD) with 95% confidence intervals (CIs) were computed. Thirteen examinations from 2009 to 2023 were enrolled for the present meta-analysis, including 808 individuals with BWs. PRP had significantly shorter healing time (MD, -5.80; 95% CI, -7.73 to -3.88, p < 0.001), higher healing rate (OR, 3.14; 95% CI, 2.05-4.80, p < 0.001), higher healed area percent (MD, 12.67; 95% CI, 9.79-15.55, p < 0.001) and higher graft take area percent (MD, 4.39; 95% CI, 1.51-7.26, p = 0.003) compared with standard therapy in patients with BW. However, no significant difference was found between PRP and standard therapy in graft take ratio (OR, 1.70; 95% CI, 0.86-3.34, p = 0.13) and infection rate (OR, 0.55; 95% CI, 0.20-1.47, p = 0.23) in patients with BW. The examined data revealed that PRP had a significantly shorter healing time, a higher healing rate, a higher healed area percent and a higher graft take area percent; however, no significant difference was found in graft take ratio or infection rate compared with standard therapy in patients with BW. Yet, attention should be paid to its values since all of the selected examinations had a low sample size and some comparisons had a low number of selected studies.

Adjusted green spectrophotometric determination of favipiravir and remdesivir in pharmaceutical form and spiked human plasma sample using different chemometric supported models.

The environmentally friendly design of analytical methods is gaining interest in pharmaceutical analysis to reduce hazardous environmental impacts and improve safety and health conditions for analysts. The adaptation and integration of chemometrics in the development of environmentally friendly analytical methods is strongly recommended in the hope of promising benefits. Favipiravir and remdesivir have been included in the COVID-19 treatment guidelines panel of several countries. The main objective of this work is to develop green, tuned spectrophotometric methods based on chemometric based models for the determination of favipiravir and remdesivir in spiked human plasma. The UV absorption spectra of favipiravir and remdesivir has shown overlap to some extent, making simultaneous determination difficult. Three advanced chemometric models, classical least squares, principal component regression, and partial least squares, have been developed to provide resolution and spectrophotometric determination of the drugs under study. A five-level, two-factor experimental design has been used to create the described models. The spectrally recorded data of favipiravir and remdesivir has been reviewed. The noise region has been neglected as it has a negative impact on the significant data. On the other hand, the other spectral data provided relevant information about the investigated drugs. A comprehensive evaluation and interpretation of the results of the described models and a statistical comparison with accepted values have been considered. The proposed models have been successfully applied to the spectrophotometric determination of favipiravir and remdesivir in pharmaceutical form spiked human plasma. In addition, the environmental friendliness of the described models was evaluated using the analytical eco-scale, the green analytical procedure index and the AGREE evaluation method. The results showed the compliance of the described models with the environmental characteristics.

The Future of Mine Safety: A Comprehensive Review of Anti-Collision Systems Based on Computer Vision in Underground Mines.

Underground mining operations present critical safety hazards due to limited visibility and blind areas, which can lead to collisions between mobile machines and vehicles or persons, causing accidents and fatalities. This paper aims to survey the existing literature on anti-collision systems based on computer vision for pedestrian detection in underground mines, categorize them based on the types of sensors used, and evaluate their effectiveness in deep underground environments. A systematic review of the literature was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to identify relevant research work on anti-collision systems for underground mining. The selected studies were analyzed and categorized based on the types of sensors used and their advantages and limitations in deep underground environments. This study provides an overview of the anti-collision systems used in underground mining, including cameras and lidar sensors, and their effectiveness in detecting pedestrians in deep underground environments. Anti-collision systems based on computer vision are effective in reducing accidents and fatalities in underground mining operations. However, their performance is influenced by factors, such as lighting conditions, sensor placement, and sensor range. The findings of this study have significant implications for the mining industry and could help improve safety in underground mining operations. This review and analysis of existing anti-collision systems can guide mining companies in selecting the most suitable system for their specific needs, ultimately reducing the risk of accidents and fatalities.

Efficacy of pentasodium diethylenetriamine pentaacetate in ameliorating anosmia post COVID-19.

BACKGROUND: COVID-19 has been frequently demonstrated to be associated with anosmia. Calcium cations are a mainstay in the transmission of odor. One of their documented effects is feedback inhibition. Thus, it has been advocated that reducing the free intranasal calcium cations using topical chelators such as pentasodium diethylenetriamine pentaacetate (DTPA) could lead to restoration of the olfactory function in patients with post-COVID-19 anosmia. METHODOLOGY: This is a randomized controlled trial that investigated the effect of DTPA on post-COVID-19 anosmia. A total of 66 adult patients who had confirmed COVID-19 with associated anosmia that continued beyond three months of being negative for SARS-CoV-2 infection. The included patients were randomly allocated to the control group that received 0.9 % sodium chloride-containing nasal spray or the interventional group that received 2 % DTPA-containing nasal spray at a 1:1 ratio. Before treatment and 30 days post-treatment, the patients' olfactory function was evaluated using Sniffin' Sticks, and quantitative estimation of the calcium cations in the nasal mucus was done using a carbon paste ion-selective electrode test. RESULTS: Patients in the DTPA-treated group significantly improved compared to the control group in recovery from functional anosmia to hyposmia. Additionally, they showed a significant post-treatment reduction in the calcium concentration compared to the control group. CONCLUSION: This study confirmed the efficacy of DTPA in treating post-COVID-19 anosmia.

Simultaneous green TLC determination of nirmatrelvir and ritonavir in the pharmaceutical dosage form and spiked human plasma.

Quantitative analysis of pharmaceutical compounds up to Nano gram levels is highly recommended to introduce feasible and sensitive tool for determination of the compounds in the pharmaceutical and biological samples. Nirmatrelvir plus ritonavir was recently approved in the US, the UK and Europe as a new co-packaged dosage form for the treatment of COVID-19. The objective of this work was to develop a more sensitive TLC method based on using ß-cyclodextrin as a chiral selector additive in the mobile phase for simultaneous determination of nirmatrelvir and ritonavir in pure form, pharmaceutical formulation and spiked human plasma. The analysis procedures were developed using TLC aluminum silica gel plates and methanol-water- 2% urea solution of ß-cyclodextrin (40:10:.5, by volume) as a mobile phase with UV detection at 215 nm. The developed method was successfully applied over a linearity range of 10-50 ng/band for both nirmatrelvir and ritonavir. The method was validated for limits of detection and quantitation, accuracy, precision, specificity, system suitability, and robustness. Furthermore, the eco-friendliness of the proposed method was assessed using the analytical eco-scale and the green analytical procedure index. The described method exhibited compliance with green analytical chemistry principles based on common green metric values.

The impact of COVID-19 pandemic on the mortality and morbidity of patients undergoing trauma surgery: a report from the UK Corona TRAUMA Surge (UKCoTS) study.

PURPOSE: To assess the impact of the COVID-19 pandemic on the outcomes of the patients who underwent trauma surgery during the peak of the pandemic. METHODS: The UKCoTS collected the postoperative outcomes of consecutive patients who underwent trauma surgery across 50 centres during the peak of the pandemic (April 2020) and during April 2019. RESULTS: Patients who were operated on during 2020 were less likely to be followed up within a 30-day postoperative period (57.5% versus 75.6% p <0.001). The 30-day mortality rate was significantly higher during 2020 (7.4% versus 3.7%, p <0.001). Likewise, the 60-day mortality rate was significantly higher in 2020 than in 2019 (p <0.001). Patients who were operated on during 2020 had lower rates of 30-day postoperative complications (20.7% versus 26.4%, p <0.001). CONCLUSIONS: Postoperative mortality was higher during the first wave of the COVID-19 pandemic compared to the same period in 2019, but with lower rates of postoperative complications and reoperation.

Adjusted green HPLC determination of nirmatrelvir and ritonavir in the new FDA approved co-packaged pharmaceutical dosage using supported computational calculations.

The greening of analytical methods has gained interest in the quantitative analysis field to reduce environmental impact and improve safety health conditions for analysts. Nirmatrelvir plus ritonavir is a new FDA approved co-packaged medication developed for the treatment of COVID-19. The aim of this research was to develop green fitted HPLC method using pre experimental computational testing of different stationary phases as well as selecting mobile phase regarding to green analytical chemistry principles. Computational study was designed to test the physical interaction between nirmatrelvir and ritonavir and different columns (C8, C18, Cyano column). The study showed that the C18 column was better for simultaneous HPLC analysis of the cited drugs. Regarding to green point of view, mobile phase consisted of ethanol: water (80:20, v/v) provided an efficient chromatographic separation of nirmatrelvir and ritonavir within a short analytical run time, reasonable resolution and excellent sensitivity. Isocratic elution was performed on a selected C18 column and a green adjusted mobile phase at flow rate of 1 mL/min and UV detection at 215 nm. The chromatographic system allowed complete baseline separation with retention times of 4.9 min for nirmatrelvir and 6.8 min for ritonavir. The method succeeded to determine nirmatrelvir and ritonavir over the concentration range of 1.0-20.0 µg/mL in the pure form and in pharmaceutical dosage form. Greenness profiles of the applied HPLC method was assessed using analytical eco-scale, the green analytical procedure index and the AGREE evaluation method. The results revealed adherence of the described method to the green analytical chemistry principles. The authors hope to provide a promising challenge for achieving green goals through integrating computational tools and applying them with green assessment metrics.

The forms and adverse effects of insecurities among internally displaced children in Ethiopia.

BACKGROUND: Ethiopia has seen an increase in the number of internally displaced persons (IDPs) due to conflict and violence related to border-based disputes and climate change. This study examines the insecurities experienced by IDPs in the Burayu camp and how they navigate and challenge them. Violence and insecurity have daunted Ethiopian regions for decades, violated children's rights, and impeded the achievement of the United Nation's sustainable development goals related to children, such as good healthcare and mental health, quality education, clean water, and sanitation. The deteriorating security concerns in Ethiopia could also expose IDP children to poor health outcomes associated with a lack of access to healthcare services. METHODS: This was an exploratory qualitative case study guided by intersectionality theoretical lens to explore the forms of insecurities perceived and experienced by IDPs in Ethiopia. Participants were selected using a purposeful sampling approach. We interviewed 20 children, 20 parents or guardians, and 13 service providers. Interviews were audio recorded and transcribed verbatim in Afan Oromo, then translated into English. We used NVivo 12 qualitative data analysis software to analyze data following Braun & Clarke's approach to thematic data analysis. RESULTS: The participants reported that IDP children in Burayu town faced many challenges related to poor socioeconomic conditions that exposed them to several insecurities and negatively affected their well-being. They reported inadequate access to clothing and shelter, clean water, sanitary facilities, food, and adequate healthcare due to financial barriers, lack of drugs, and quality of care. Our data analysis shows that socioeconomic and contextual factors intersect to determine the health and well-being of children in the Ethiopian IDP camp studied. The children experienced insecurities while navigating their daily lives. This is compounded by institutional practices that shape gender relations, income status, and access to healthcare, education, and food. These deficiencies expose children to traumatic events that could decrease future livelihood prospects and lead to compromised mental health, rendering them susceptible to prolonged post-traumatic stress disorder and depression. Results are presented under the following topics: (1) basic needs insecurity, (2) healthcare insecurity, (3) academic insecurity, (4) economic insecurity, (5) food insecurity, and (6) physical and mental health insecurity. CONCLUSION: Successful relocation and reintegration of IDPs would help to alleviate both parent and child post-conflict stressors. Managing and following up on economic reintegration efforts is needed in both the short and long term. Such measures will help to achieve goals for specific projects attached to donor support outcomes, consequently enabling social support and conflict resolution management efforts.

Impact of negative pressure wound drainage compared with natural wound drainage after thyroid tumour surgery: A meta-analysis.

We conducted a meta-analysis to compare the effectiveness of negative pressure wound drainage to that of spontaneous wound drainage after thyroid tumour surgery. A thorough analysis of the literature up to July 2022 revealed that, of the 1234 patients who used surgery for thyroid tumours, 615 used negative pressure wound drainage and 619 used natural wound drainage. To measure the influence of negative pressure wound drainage in comparison to natural wound drainage following thyroid tumour surgery, mean difference (MD) and odds ratio (OR) with 95% confidence intervals (CIs) were measured using the contentious and dichotomous approaches with a random or fixed-effect model. Subjects who used negative pressure wound drainage had significantly higher averages for drained material (OR, 12.52; 95% CI, 6.78-18.26, P = 0.001), shorter drain placement times (MD, -1.06; 95% CI, 1.57 to -0.55, P = .001), lower rates of infection at the surgical site (OR, 0.17; 95% CI, 0.05-0.60, P = .006), higher rates of wound healing (OR, 5.91; 95% CI, 1.56-22.34, P = .009), and lower rate of wound seroma (OR, 0.21; 95% CI, 0.10-0.42, P < .001) in subjects after thyroid tumour surgery in comparison to subjects who used natural wound drainage after thyroid tumour surgery. Those who used negative pressure wound drainage had significantly higher averages of drained material, shorter drain placement times, lower rates of wound infection at the surgical site, higher rates of wound healing, and lower rates of wound seroma. Care must be used when analysing the results because of the small sample size of 7 of the 13 studies included in the meta-analysis and the lack of studies in several comparisons.

Quercetin: Putative effects on the function of cryopreserved sperms in domestic animals.

Quercetin is one of the most used antioxidant flavonoids and largely exists in many fruits and vegetables because of its capability to scavenge the free reactive oxygen species (ROSs) by repressing lipid peroxy radical fusion, metal ion chelating through enzyme inhibition, and adopting the repair mechanisms. It also exhibits various biological actions, including antioxidative, anti-inflammatory and antimicrobial activities. Furthermore, it contributes well to sustaining the endogenous cellular antioxidant defence system. The process of cryopreservation is associated with increased oxidative stress, and some steps are potential sources of ROSs, including the method of semen collection, handling, cryopreservation culture media, and thawing, which result in impaired sperm function. Several antioxidants have been proposed to counteract the harmful impact of ROS during semen cryopreservation. The antioxidant capability of quercetin has been verified in different animal species for providing valuable defence to sperm during the cryopreservation process. The beneficial properties of quercetin on various parameters of fresh and post-thaw sperm in different species are clarified in this review. More in-depth investigations are required to clarify quercetin's mechanism of action in different animal species.

Rotator Cuff Repair With Patch Augmentation: What Do We Know?

Background: Repair of massive rotator cuff tears remains a challenging process with mixed success. There is a growing interest in the use of patches to augment the repair construct and the potential to enhance the strength, healing, and associated clinical outcomes. Such patches may be synthetic, xenograft, or autograft/allograft, and a variety of techniques have been tried to biologically enhance their integration and performance. The materials used are rapidly advancing, as is our understanding of their effects on rotator cuff tissue. This article aims to evaluate what we currently know about patch augmentation through a comprehensive review of the available literature. Methods: We explore the results of existing clinical trials for each graft type, new manufacturing methods, novel techniques for biological enhancement, and the histological and biomechanical impact of patch augmentation. Results: There are promising results in short-term studies, which suggest that patch augmentation has great potential to improve the success rate. In particular, this appears to be true for human dermal allograft, while porcine dermal grafts and some synthetic grafts have also had promising results. Conclusion: However, there remains a need for high-quality, prospective clinical trials directly comparing each type of graft and the effect that they have on the clinical and radiological outcomes of rotator cuff repair.

Arthroscopic Allograft Bone Block Procedure with Remplissage for Bipolar Lesions.

Anterior shoulder instability with bone loss is a challenging condition. The two most performed procedures, Bankart repair & Latarjet, are not without issues. We describe a technique where arthroscopic free bone grafting was performed in conjunction with remplissage. We feel that this combined arthroscopic procedure offers advantages that include reduced risk of conventional Latarjet complications, including neurological deficits and metal hardware complications while preserving subscapularis and coracoid. Furthermore, these advantages may not come at the cost of compromised outcomes, particularly recurrence rate, as the remplissage may compensate for the possible lack of "sling effect" with free bone graft reconstruction.
