Introduction: The acromioclavicular joint is a superficial diarthrodial joint that surrounds the medial articular facet of the acromion and the distal portion of the clavicle. Due to its anatomy and biomechanics, it is highly susceptible to trauma and in young men who play contact sports, acromioclavicular dislocation is common. This article aimed to systematically review the literature and compare the surgical techniques used in the treatment of acromioclavicular dislocation in patients who practice sports. Methods: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Eligible studies for this systematic review included articles in English or Spanish published between 2013 and 2023, which mention the occurrence of acromioclavicular dislocation during sports practices. Additionally, only studies that addressed the surgical treatment of acromion-clavicular dislocation and contained original data on the topic were included. Results: We found 144 eligible studies after searching the LILACS and PubMed databases. Based on the inclusion and exclusion criteria and the reviewers’ consensus, we selected four studies for the systematic review. 133 patients with AC joint displacement were evaluated. Mean Age: approximately 31.90 years. 81.92 of these injuries occurred during sports practice. Surgical Procedures Used: titanium plates fixation (49 patients), arthroscopy (24), single tunnel technique (30) and coracoid sling technique (30). The results of the visual analog scale and Constant-Murley scores varied between the techniques used. Twenty-two complications after surgical treatment were identified. Conclusion: A significant variability of operative techniques can be used in the surgical approach of acromioclavicular dislocation, such as arthroscopy, single tunnel, coracoid sling and titanium plates. Although it presented excellent functional results compared to the other three tech

Keloid of Ears: Recurrence and Its Complications

Modern Plastic Surgery 2021年第1期11卷 6-13页

In this case report, we present a male patient who arrived at the hospital for the first time at the age of 8 with giant keloids in both ears and diagnosed by the Dermatology and Plastic Surgery as having the “Disease of Jorge Lobo”, which is a fungal infection due to the story of the endemic characteristics. After the first surgical intervention, he received guidance from the team for keloids and left the hospital using elastic mesh and a request to change the place where he lived to reduce his contact with the fungi. Fourteen years later, the patient returned to the Plastic Surgery Service having even larger keloids in both ears, twice the size than the first time. We did the second surgical intervention to remove it, but with the patient’s commitment that he would correctly comply with the guidelines determined by the surgical team. After finishing all the steps and a post-operative for the case, we observed the satisfaction and the increase of the patient’s mood, happier and without the embarrassment of that physical defect.

Antioxidants Enzymes Activities and NO Levels in Hemodialysis and Continuous Ambulatory Peritoneal Dialysis—A Comparative Study

Journal of Biosciences and Medicines 2024年第2期12卷 50-59页

It consists of a retrospective study with twenty-two individuals diagnosed with DRC: fourteen HD and eight CAPD, followed up in the dialysis center of Antonio pedro University Hospital (HUAP) of Fluminense Federal University (UFF), between 2015 and 2017. Fifteen healthy control (HC) subjects were included, without diagnosed CKD. Patients with HIV positive, hepatitis A, B, and C, pregnant, cancer, smokers, alcoholics and those exposed to X-rays in the last 3 months, were excluded. Objectives: As oxidative stress and endothelial dysfunction may be linked to the higher prevalence of CVD in CKD patients, we measured the activities of the antioxidants enzymes: SOD and GPx and total NO levels in the plasma and serum of end-stage CKD patients undergoing dialysis therapy, comparing with the HC group. Methods: Quantification of NO levels was performed by fluorometric kit, while activities of SOD and GPx were determined using kinetic methods. Results: We found higher plasma SOD activity in HD (8.58 U/ml) and CAPD (10.14 U/ml), compared to C (3.73 U/ml) group, while GPx activity was decreased in HD (115.38 nmol/h/ml) and CAPD (122.76 nmol/h/ml) groups compared to HC group (275.83 nmol/h/ml). Total serum NO concentration was decreased in HD (14.09 pmol/μl) and CAPD (10.26 pmol/μl), compared to non-CKD patients (49.65 pmol/μl). Conclusion: Decreased total serum NO and GPx activities may lead to endothelial dysfunction and consequently a higher prevalence of CVD in CKD patients.

Dexamethasone intravitreal implant(Ozurdex) in diabetic macular edema: real-world data versus clinical trials outcomes

AIM: To investigate the safety and efficacy of intravitreal dexamethasone implants(Ozurdex?/DEX) in patients with diabetic macular edema(DME) either na?ve or nonna?ve to anti-VEGF therapies who switched to DEX implant independent of response to anti-vascular endothelial growth factors(anti-VEGFs).METHODS: This was an audit retrospective review of medical records of patients with DME who switched to the DEX intravitreal implant. Patients were divided into 2 groups: patients na?ve to antiangiogenic therapy and patients who were previously treated with anti-VEGFs. Data regarding demographics, changes in mean best-corrected visual acuity(BCVA), central macular thickness(CMT), and intraocular pressure(IOP) was collected over 6 mo. The demographic data mean changes in BCVA, CMT, and IOP were compared. Six-month follow-up data of 47 patients(57 eyes), who either switched to DEX implant irrespective of response to previous treatments or were treatment na?ve before receiving DEX implant, was ***: Improvement in mean BCVA was observed from 1-4 mo after injection with a decreased effect at month 6 as expected, with better outcomes in na?ve compared to non-na?ve patients. A statistically relevant decrease in mean CMT was observed during the follow-up period. An increase in mean IOP was observed in the first 2 mo after DEX therapy. The mean number of injections of the overall population during the 6 mo was 1.3. A subgroup analysis showed no relevant difference between phakic versus pseudophakic patients relative to measured outcomes. There was no cataract progression during the follow-up period and no adverse events ***: This real-life setting study shows that intravitreal DEX implant is effective and safe. The timings of greater therapeutic impact are concordant with previous studies and suggest that earlier treatment with corticosteroids may have an additional benefit in na?ve patients.
