The use of Fibrin Sealants in Reducing Drain Output in Abdominoplasty: Is it Useful?

Background: Abdominoplasty is a common surgical procedure in which excess abdominal skin and fat are reduced to improve body contouring. Fibrin sealant has been proposed to reduce postsurgical bleeding and exudation. In this study, we evaluated whether there was a significant statistical difference in surgical output between the use of fibrin glue and its nonuse in abdominoplasty surgery, specifically in reducing bleeding and exudation. Material and methods: A retrospective chart review of 68 postbariatric abdominoplasty patients (58 females, 10 males) was performed. We divided the patients into Group A (30 cases, 44%), in which we used fibrin sealant, and Group B (38 cases, 56%), in which we did not use fibrin glue. We calculated the total amount of liquid in suction drainages until the day of their removal. Statistical analysis included the independent t-test with a significance level of 0.05. Results: The average drainage output in Group A was 620.0 ± 375.0 mL, whereas in Group B, it was 500.0 ± 290.0 mL. Results indicate an insignificant correlation between the use of fibrin glue and the amount of liquid in the surgical drains (t = 1.52, p = 0.13). The result is not significant at p <.05 according to the independent t-test. Conclusion: The use of fibrin sealant surely has a high value in all surgical branches to reduce postoperative complications, but in our study, we did not find any advantages in its use for reducing surgical drain output in abdominoplasty patients.

Typical values of z-resolution for different Digital Breast Tomosynthesis systems evaluated in a multicenter study.

PURPOSE: The aim of the present study, conducted by a working group of the Italian Association of Medical Physics (AIFM), was to define typical z-resolution values for different digital breast tomosynthesis (DBT) models to be used as a reference for quality control (QC). Currently, there are no typical values published in internationally agreed QC protocols. METHODS: To characterize the z-resolution of the DBT models, the full width at half maximum (FWHM) of the artifact spread function (ASF), a technical parameter that quantifies the signal intensity of a detail along reconstructed planes, was analyzed. Five different commercial phantoms, CIRS Model 011, CIRS Model 015, Modular DBT phantom, Pixmam 3-D, and Tomophan, were evaluated on reconstructed DBT images and 82 DBT systems (6 vendors, 9 models) in use at 39 centers in Italy were involved. RESULTS: The ASF was found to be dependent on the detail size, the DBT angular acquisition range, the reconstruction algorithm and applied image processing. In particular, a progressively greater signal spread was observed as the detail size increased and the acquisition angle decreased. However, a clear correlation between signal spread and angular range width was not observed due to the different signal reconstruction and image processing strategies implemented in the algorithms developed by the vendors studied. CONCLUSIONS: The analysis led to the identification of typical z-resolution values for different DBT model-phantom configurations that could be used as a reference during a QC program.

2015 Recommendations for the management of polymyalgia rheumatica: a European League Against Rheumatism/American College of Rheumatology collaborative initiative

Therapy for polymyalgia rheumatica (PMR) varies widely in clinical practice as international recommendations for PMR treatment are not currently available. In this paper, we report the 2015 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) recommendations for the management of PMR. We used the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology as a framework for the project. Accordingly, the direction and strength of the recommendations are based on the quality of evidence, the balance between desirable and undesirable effects, patients' and clinicians' values and preferences, and resource use. Eight overarching principles and nine specific recommendations were developed covering several aspects of PMR, including basic and follow-up investigations of patients under treatment, risk factor assessment, medical access for patients and specialist referral, treatment strategies such as initial glucocorticoid (GC) doses and subsequent tapering regimens, use of intramuscular GCs and disease modifying anti-rheumatic drugs (DMARDs), as well as the roles of non-steroidal anti-rheumatic drugs and non-pharmacological interventions. These recommendations will inform primary, secondary and tertiary care physicians about an international consensus on the management of PMR. These recommendations should serve to inform clinicians about best practices in the care of patients with PMR.(AU)
