PURPOSE To analyze the factors related to changes in astigmatism before and after suture removal in patients who underwent penetrating keratoplasty (PK). METHODS The study group consisted of 171 consecutive PKs in 171 patients. Keratometric astigmatism was measured before and after suture removal in all patients. The vectorial difference for each eye was calculated between the examination bef...

BACKGROUND Chronic noninsertional Achilles tendinosis can result in an acute Achilles tendon rupture with a short distal stump. In such tendon ruptures, there is a limited amount of adequate tissue that can hold suture, thus presenting a challenge for surgeons who elect to treat the rupture operatively. HYPOTHESIS Adding suture anchors to the repair construct may result in biomechanically str...

BACKGROUND Double-eyelid blepharoplasty is a popular aesthetic surgery in Asians. However, the buried suture technique is associated with complications related to implantation of the suture thread. The present study was performed to identify optimal surgical suture removal techniques in Japanese patients with suture-related complications after buried suture double-eyelid blepharoplasty. METHO...

- healing of surgical wounds and their complications such as infection or scar formation are of major concern in surgery. tissue glues are advanced to reduce these problems. in a prospective study, we have evaluated surgical wound healing in 76 patients whose surgical wounds were repaired by tissue glues (histoacryl). this study was performed in four leaching hospitals (sina, shariaty, shohada,...

Cranial suture development involves a complex interaction of genes and tissues derived from neural crest cells (NCC) and paraxial mesoderm. In mice, the posterior frontal (PF) suture closes during the first month of life while other sutures remain patent throughout the life of the animal. Given the unique NCC origin of PF suture complex (analogous to metopic suture in humans), we performed quan...

The ecdysial suture is the region of the arthropod exoskeleton that splits to allow the animal to emerge during ecdysis. We examined the morphology and composition of the intermolt and premolt suture of the blue crab using light microscopy and scanning electron microscopy. The suture could not be identified by routine histological techniques; however 3 of 22 fluorescein isothiocyanate-labeled l...

BACKGROUND The authors present a novel mesh suture design aimed at minimizing the early laparotomy dehiscence that drives ventral hernia formation. The authors hypothesized that modulation of the suture-tissue interface through use of a macroporous structure and increased aspect ratio (width-to-height ratio) would decrease the suture pull-through that leads to laparotomy dehiscence. METHODS I...

It is believed that Greater India migrated from the southern hemisphere, collided with Gondwanaland, Angaraland and Cathaysia, thereby closing an intervening oceanic Tethys along the Indus-Yarlung-Tsangpo Suture Zone (IYTSZ).The suture zone is placed along the Chaman Fault in the Baluchistan-Afghanistan area in the west, and the Indus-Yarlung-Tsangpo in the north, whereas along the east from Th...
