Background: Vitreous floaters are a common and inconvenient phenomena. This study aims to examine the efficacy and safety in treating vitreous floaters using Nd:YAG laser vitreolysis. Methods: In this prospective double-blinded randomized clinical trial 24 eyes of twenty-four patients were randomized into intervention with YAG laser vitreolysis and control groups. Primary outcomes were visual disturbance on a 10-point scale, qualitative changes in a 4-level scale, contrast sensitivity measured with the Pelli-Robson table and the National Eye Institute Visual Functioning Questionnaire 25 (NEI VFQ-25). Secondary results included objective change in vitreous opacities, best-corrected visual acuity (BCVA), variation in intraocular pressure (IOP) and other adverse events. Results: Twenty-one patients (21 eyes; 5 male, 16 female) were enrolled in this study (mean age 62 ± 7.9 years), three were lost during follow-up. In the YAG laser group, the 10-point visual disturbance score improved a mean of 4.7 points ( p < 0.001) compared to the control group that improved 2.1 ( p = 0.09). The YAG laser group reported greater subjectively symptomatic improvement (77%) than controls (25%). NEI VFQ-25 revealed improved general vision (75.8 versus 59.2; p = 0.037) and in mental health at 6 months (84.3 versus 70.3; p = 0.048). There was no significant difference in contrast sensitivity ( p = 0.848) and in IOP ( p = 0.505). No differences in adverse events between groups were identified. Conclusion: Vitreolysis with Nd:YAG laser improves visual results in patients with symptomatic vitreous floaters, without adverse events considered clinically relevant. Other trials with a larger number of participants are required to corroborate these results.

Abstract Background Minimally invasive or noninvasive skin-tightening procedures have become trends in facial and neck rejuvenation. Radiofrequency-assisted liposuction (RFAL) is a new choice for the treatment of skin relaxation that is more effective than noninvasive surgery without surgical incision. Objectives The authors recommend a 2-step method in which radiofrequency is applied after appropriate liposuction is performed. This approach is safer and more effective than traditional RFAL, and the authors detail the safety guidelines, operative techniques, postoperative satisfaction results, and complications. Methods A total of 227 patients with lower face and neck skin laxity underwent RFAL between April 2012 and June 2019. The following data were collected: age, body mass index, operative duration, volume of fat aspirated, amount of energy delivered, and number and type of complications. Patient satisfaction was surveyed postoperatively and assessed by third-party surgeons at 3 and 6 months. Results At 6 months after operation, 78.8% of patients considered the results moderate to excellent, whereas 21.2% of the patients considered the results to be poor or thought there was no change. The photograph evaluation performed by independent plastic surgeons showed moderate to excellent results in 89.1% of patients. There were no major complications that required further medical or surgical intervention. Conclusions This 2-step method is a safe and effective improvement in the application of radiofrequency for face and neck skin tightening. Patients can achieve significant contour correction via minimally invasive surgery with a lower risk of side effects. Level of Evidence: 4

Abstract As life expectancy has prolonged nowadays, interest has increased to change patterns of life, which include improving the consequences of skin ageing through slowing the ageing process. There are two main processes of skin ageing either intrinsic or extrinsic. Intrinsic ageing reflects genetic background in which skin appears thin with exaggerated expression lines. However, extrinsic ageing is caused by external factors such as smoking, excessive use of alcohol, poor nutrition and sun exposure. Extrinsically aged skin appears predominantly not only by wrinkles, but also by pigmented lesions such as freckles, lentigines and patchy hyperpigmentation, and depigmented lesions such as guttate hypomelanosis. Epidermal and dermal atrophy, rough skin texture, flushing, erythema, telangiectasias, dilated pores and loss of tone and elasticity are also other signs of skin aging. Over the past few years, the use of Mesobotox has broadened and it is now commonly used as rejuvenation procedure with different dilutions. Our work aimed to compare between three commonly used dilutions of Mesobotox regarding its efficacy and safety, as this comparison was not done previously. Aim of the study The aim of this work is to evaluate and compare between different dilutions of Mesobotox in mid and / or lower facial rejuvenation. Patients and methods We included 30 patients complaining of facial wrinkles. Patients were divided into three equal groups to study three different dilutions of Mesobotox 1:5, 1:7 and 1:10. Assessment of treatment response was done using 3D Antera camera. Results Assessment of treatment response using Antera camera in 1:5 dilution revealed statistically significant improvement in all the parameters (periorbital and midface) with more evident improvement after 1 month of treatment compared to after 6 months of treatment. With 1:7 dilution and 1:10 dilution, response revealed statistically significant improvement in most of the parameters (periorbital and midface) with more evident improvement after 1 month of treatment compared to after 6 months of treatment.
