These clinical results support the use of short implants as an effective and safe long-term treatment option.

PRGF eye-drops could be a safe and effective therapeutic option for patients with stages 2-3 of NK, showing high rates of corneal defect/ulcer resolution in short times, either in reducing signs and symptoms of NK, and therefore preventing the progression of NK to greater ocular complications.

The aim of this meta-analysis was to evaluate the efficacy and safety of two bisphosphonates (alendronate and zoledronate) in the treatment of postmenopausal osteoporosis. The incidence of fractures was considered as primary endpoint. Only randomized trials with a follow-up period of 1 year or more were included in this systematic review and meta-analysis. We excluded studies that included patients with secondary osteoporosis especially in relation to therapy with corticosteroids or other drugs or diseases known to affect bone mineral density. Studies published as subgroup analysis, extension studies, economic evaluations, and comparisons with active control were excluded. The methodological quality of controlled clinical trials that met these inclusion criteria was evaluated. No studies were excluded from analysis due to lack of quality. The risk ratio of hip, vertebral and wrist fractures for alendronate were 0.61 [95% confidence interval (CI) 0.40-0.93], 0.54 (95% CI 0.44-0.66) and 0.65 (95% CI 0.33-1.25), respectively. Zoledronate risk ratio was 0.62 (95% CI 0.46-0.82) and 0.38 (95% CI 0.22-0.67) for hip and vertebral fractures, respectively.

Purpose: To provide preliminary information about the safety and efficacy of plasma rich in growth factors (PRGF) in the treatment of evaporative dry eye (EDE) and analyze the influence of certain variables on treatment outcomes. Methods: This retrospective study included patients with EDE treated between January 2011 and December 2013. Outcome measures including signs and symptoms of the disease were evaluated before and after treatment. The influence of some of the patient's clinical variables on results was assessed. Safety assessment was also performed. Results: Eighty-three patients with a total of 156 eyes were evaluated. Statistically significant reductions in the Ocular Surface Disease Index (38.2%), best-corrected visual acuity (27.4%), Visual Analogue Scale scores for frequency (32%) and severity (34%), and a significant improvement in the Schirmer test scores (177.5%) were observed (p < 0.05). The results were stratified according to the identified potential effect modifiers. Only four adverse events were reported. All of them were mild and resolved within a few days. Conclusions: Results suggest that PRGF eye drops could be a safe and effective treatment in reducing EDE signs and symptoms. When treating patients, the possible influence of some clinical variables must be taken into account.
