Background: Meniscal root tears cause biomechanical changes comparable to a total meniscectomy. The resultant compromise in hoop stress, leads decreased tibiofemoral contact area and increased pressure. This will lead early arthritis. meniscus tear causes more detrimental people with varus alignment of the lower limb. increases chances progression arthritis, causing joint pain functional limita...

BACKGROUND Our objective was to analyze the causes, timing, and results of reoperation after primary repair for acute type A dissection. METHODS One hundred and four consecutive patients underwent a reoperation after previous type A aortic dissection repair (1972 to 2008). Supracoronary ascending aorta replacement (SCAR) was commonly performed during primary repair and it was associated with ...

BACKGROUND The study sought to determine dynamic changes and theoretical bases of a clinical diagnostic test, the tear clearance rate. METHODS Thirty four healthy subjects ranging in age from 22 to 84 years underwent examination of tear clearance rate, the Schirmer test with anaesthesia, as well as fluorophotometric measurement of tear turnover, tear volume, and tear flow. By applying 0.5% fl...

As a previously unrecognized late graft-related complication, we report a case of spontaneous perigraft hemorrhage, which was evidenced by contrast extravasation on computed tomographic scan seven years after thoracic aortic replacement with a knitted Dacron graft. There was no anastomotic problem or graft tear, and the hematoma seemed to result from transgraft hemorrhage. Inadequate graft heal...

Left coronary cusp perforation is an extremely rare consequence of blunt chest trauma. A 22-year-old male presented after a motor vehicle accident with dyspnea. Transthoracic echocardiogram (TTE) and transesophageal echocardiogram (TEE) showed moderate to severe aortic regurgitation with prolapsing right coronary cusp. In the operating room he was found to have a left coronary cusp tear near th...

The frozen elephant procedure, as a hybrid method to treat aortic pathologies involving the aortic arch and the proximal descending aorta, has become an accepted treatment option. We report two late fractures of the nitinol stents of the endograft of an early frozen elephant trunk prosthesis. One patient suffered from a tear of the woven polyester fabric, causing a Type III endoleak and rapid p...

The objective of this exploratory qualitative study was to describe (1) the key factors affecting women's initial decision to explore the use of bioidentical hormone, (2) where women gather their information on bioidentical hormones, (3) the enablers and barriers to obtaining bioidentical hormones, and (4) how to improve the bioidentical hormone replacement therapy access path. The study was co...

A 73-year-old woman had undergone hemiarch replacement with primary entry resection for treating acute type A dissection 6 years ago. Postoperative computed tomography (CT) showed a patent false lumen (FL) in the aortic arch and a reentry tear in the right subclavian artery. The remaining aortic arch enlarged, which resulted in formation of a 55-mm-diameter aneurysm. We performed reentry occlus...

Meniscal cartilage tears are common and predispose to osteoarthritis (OA). Most occur in the avascular portion of the meniscus where current repair techniques usually fail. We described previously the use of undifferentiated autologous mesenchymal stem cells (MSCs) seeded onto a collagen scaffold (MSC/collagen-scaffold) to integrate meniscal tissues in vitro. Our objective was to translate this...
