001 each). In the PCG group, negative correlation was observed between VA and total densitometry (r=-0.49; P=0.004).

Patients with PCG and healthy subjects display differences in corneal densitometry and topographic measurements. PCG patients show greater corneal density with an inverse relationship between visual acuity and higher elevation (anterior and posterior values).

Compliance is considered to be a major property influencing the long term performances of synthetic vascular substitutes that could play a role in anastomotic false aneurysm and intimal hyperplasia stenosis onset. Over the last decades, manufacturers have tried to develop substitutes that mechanically mimic arterial properties and avoid a compliance mismatch at the anastomoses in particular. However, data are missing about how initial compliance properties could change with time. The goal of this study was to evaluate how the compliance of vascular grafts evolves under cyclic loading conditions invitro.

The compliance of three different models of commercially available textile polyethylene terephthalate (PET) grafts was evaluated. Tests were performed with and without their original coating. Compliance was assessed with a specific device dedicated to measure the deformations undergone by a graft under cyclic pressure loading conditions, using image analysis software. In each experiment, image analysis wasimental study helps explain the mismatch mentioned in clinical observations.Pulmonary lymphatic disorders are characterized by the presence of the abnormal lymphatic tissues in the thoracic cavity, presenting clinically as chylothorax, chylopericardium, chyloptysis, interstitial lung disease and plastic bronchitis. These conditions include neonatal chylothorax, cardiac and non-cardiac plastic bronchitis, non-traumatic chylothorax, post congenital cardiac surgery chylothorax and complex lymphatic malformations. Recently developed lymphatic imaging techniques, such as intranodal lymphangiography and dynamic contrast enhanced magnetic resonance lymphangiography demonstrated abnormal pulmonary lymphatic flow from thoracic duct into pulmonary parenchyma as a pathophysiological mechanism of these diseases. Novel minimally invasive lymphatic interventions, such as thoracic duct embolization, interstitial lymphatic embolization and surgical lympho-venous anastomosis, provide an effective treatment of these conditions.The rapid spread of SARS-CoV-2 infection globally coupled with the relatively high case-fatality rate has led to immediate need for therapeutic intervention to prevent and treat COVID-19 disease. There is accumulating evidence that morbidity and mortality in COVID-19 may be exacerbated by a dysregulated host immune response resulting in significant hyperinflammation and cytokine release. The aim of this review is to describe the basis for the immune dysregulation caused by SARS-CoV-2 infection and to examine current investigations into immunomodulatory therapies aimed at targeting the excessive host immune response.

The in vitro creation of hyaline joint cartilage is a challenge since, to date, the ex vivo synthesis of a structured tissue with the same biomechanical and histological properties of the joint cartilage has not been achieved. Selleckchem Sunitinib To simulate the physiological conditions we have designed an in vitro culture system that reproduces joint movement.

We have developed a cell culture bioreactor that prints a mechanical stimulus on an elastin matrix, in which mesenchymal stem cells (MSC) are embedded. The first phase of study corresponds to the development of a bioreactor for hyaline cartilage culture and the verification of cell viability in the elastin matrix in the absence of stimulus. The second phase of the study includes the MSC culture under mechanical stimulus and the analysis of the resulting tissue.

After culture under mechanical stimulation we did not obtain hyaline tissue due to lack of cellularity and matrix destructuring.

The stimulus pattern used has not been effective in generating hyaline cartilage, so other combinations should be explored in future research.

When conservative treatment fails, surgical resection must be indicated. Endoscopic resection is a less invasive technique and can be considered an alternative with better functional recovery.

We performed a retrospective study of the patients with calcaneonavicular coalition operated in our hospital between 2015 and 2018. We performed an endoscopic resection. We used AOFAS scale score for the results.

We reviewed seven cases for a minimum of 12 months. AOFAS score improved from 42 before surgery to 92. There were no major complications from surgery. We had a patient with dysesthesias in the forefoot that improved at 3 months and a case of local swelling that solved with ice and rest.

Endoscopic resection has advantages over open surgery. Offers a great vision and good control of the coalition resection, provides an early rehabilitation, decrease hospital stay, improves cosmetic results and the probability of neuroma is minimum with an adequate control of the technique.

Since arthroscopy remains a controversial treatment of hip dysplasia, our objective was to analyse its clinical and radiological results in a cohort of patients with dysplasia and compare them to controls with femoroacetabular impingement (FAI).

We retrospectively analysed a series of patients who underwent hip arthroscopy for the treatment of labral pathology; 29 of them with borderline hip dysplasia and 197 with FAI, comparing reoperations and joint survival. The diagnosis of borderline dysplasia was made with a lateral centre-edge angle greater than 18° but less than 25°. The average follow-up was 43 months. We performed a multivariate regression analysis to evaluate the association of reoperations with different demographic, radiological and intraoperative variables.

Seven complications were registered in the FAI group (1 medically treated superficial wound infection, 3 pudendal nerve paraesthesias, 1 deep vein thrombosis and 2 heterotopic ossifications) and none in the dysplasia group. While 5 patients from the FAI group required a new surgery, none of the dysplasia group was re-operated (p=.
