Abstract
PURPOSE Oral Lichen planus is a potentially malignant autoimmune disorder, characterized by burning and pain in the affected mucosa which reduces the quality and comfort of patient's life. Various treatment modalities have been documented for OLP but due its malignant potential the alternative therapeutic approaches with least or no side effects are being in demand. One of such, yet unexplored treatment is Platelet rich plasma (PRP). This study aims to evaluate the effectiveness of intralesional PRP as compared to the Intralesional corticosteroids in the management of erosive OLP. MATERIALS AND METHODS The study sample consisted of 20 clinically and histopathologically confirmed patients of Erosive OLP among which 10 patients were given intralesional corticosteroids and 10 patients were administered intralesional PRP. All the patients were given weekly injections for 2 months and were followed up till 4 months for assessing the parameters such as pain/burning, erythema and size of the lesions. RESULTS The patients in both the groups showed a statistically significant reduction in all the assessed parameters of erosive lichen planus from baseline till 4 months of treatment and follow up. However, on comparison of the pain reduction, size of lesion and erythema scores between the two groups, the difference was found to be statistically insignificant. CONCLUSION The intralesional PRP was found to be of comparative effectiveness with respect to intralesional triamcinolone acetonide in the management of erosive OLP and with an added advantage of having less recurrence and no adverse effects.

Abstract
BACKGROUND Activated protein C reduces 28-day mortality in patients with severe sepsis, but its anticoagulant properties entail a risk of bleeding. OBJECTIVE The aim of this systematic review was to evaluate the prevalence of serious bleeding events in patients receiving activated protein C. METHODS We searched the MEDLINE and EMBASE databases for studies that described the prevalence of serious bleeding events and intracranial hemorrhage in patients receiving activated protein C. We calculated the bleeding rates by calculating proportions and 95% CIs for each study, and then pooled the data to derive a pooled proportion and 95% CI. RESULTS Our search yielded 17 studies, which included 10,679 patients. The occurrence of serious bleeding events in patients receiving activated protein C ranged from 0.5% to 9.6%, and the pooled prevalence was 3.3% (95% CI 2.4-4.4%) by the random effects model. The occurrence of intracranial hemorrhage ranged from 0% to 1.4%, and the pooled prevalence was 0.44% (95% CI 0.31-0.6%). Sensitivity analysis showed a higher prevalence of bleeding in the observational studies than in the randomized controlled trials. There was substantial clinical and statistical heterogeneity, but no evidence of publication bias. CONCLUSIONS Activated protein C is associated with significant risk of bleeding, so strict inclusion and exclusion criteria should be set prior to administering activated protein C.

Abstract
Multiple myeloma complicated by acute renal failure is a diagnosis often encountered by the practicing nephrologist. The role of plasmapheresis in such patients has been of interest for decades. Three randomized controlled trials (RCTs) and multiple observational trials have evaluated the potential role of plasmapheresis in the management of this condition. This systematic review presents the results of these trials regarding survival benefits, recovery from dialysis, and improvement in renal function. A comprehensive search revealed 56 articles. Of these, only 8 articles met our inclusion criteria (3 RCTs, 1 correction of results, and 4 observational trials). Two of the 3 RCTs showed no difference in survival benefit. Two of the 3 RCTs showed a greater percentage of patients stopping dialysis in the intervention group; however, these results were not reproduced in the largest trial. All the studies showed an improvement in renal function for patients receiving plasmapheresis; however, only 2 RCTs and 1 retrospective study showed a statistically significant improvement in renal function among patients who received plasmapheresis in comparison with a control group. Our systematic review does not suggest a benefit of plasmapheresis independent of chemotherapy for multiple myeloma patients with acute renal failure in terms of overall survival, recovery from dialysis, or improvement in renal function.
