Explosives create and energize particles that act as projectiles prone to further fragmentation or create other secondary missiles in the body. These fragments may result in secondary injuries. This has been repeatedly described in the orthopedic and neurosurgical literature. We report the same process for abdominal injuries after fascial penetration in the military setting. This is an observat...

Necrosis of a reconstructed organ after esophagectomy is a rare postoperative complication. However, in case this complication develops, severe infectious complications can occur, and subsequent surgical reconstruction is quite complicated. To treat esophageal conduit necrosis after esophageal reconstruction with the terminal ileum and ascending colon, we reconstructed the esophagus using a tra...

Volumetric muscle defect, caused by trauma or combat injuries, is a major health concern leading to severe morbidity. It is characterized by partial or full thickness loss of muscle and its bio-scaffold, resulting in extensive fibrosis and scar formation. Therefore, the ideal therapeutic option is to use stem cells combined with bio-scaffolds to restore muscle. For this purpose, muscle-derived ...

   Background:The aim of this study is to find out the spatial and temporal expression of TGF-b1 during the tendon healing, after application of Platelet Rich Plasma (PRP). Methods: A patellar tendon defect model in rabbits was used for this purpose. 48 skeletally mature New Zealand White rabbits, weighing 3.5 kg, were used for this study. Equal numbers of animals from both groups were sacrific...

Background: In several conditions we have face cranial bone defects. Reconstruction of these defects remains one of the most challenging problems encountered by craniofacial surgeons. Objective: To evaluate bone repair in cranial bone defects by use of an implant made of octacalcium phosphate in combination with bone matrix gelatin (OCP/BMG). Methods: We used 40, 5–6-week-old male Sprague-Dawle...

Variations in skin thickness and contours pose significant challenges to reconstruction of the lower third of the nose. Human amniotic membrane allograft offers a potential alternative to tissue transfer in reconstruction of the lower third of the nose. We reviewed the procedure and photographs of a healthy 56-year-old male with a 22 × 18 mm lower third nasal defect involving full thickness ski...

BACKGROUND Articular cartilage defect can lead to degradation of subchondral bone and osteoarthritis (OA). OBJECTIVE To determine the healing effect of transplantation of adipose-derived mesenchymal stem cells (Ad-MSCs) in full-thickness femoral articular cartilage defects in rabbit. METHODS 12 rabbits were equally divided into cell-treated and control groups. In cell-treated group, 2×10(6)...

Reconstruction of the upper lip requires symmetrical reconstruction of hairy male skin according to the aesthetic principle. A moderate defect of the upper lip had nonhairy skin on the upper one-third and hairy skin on the lower two-thirds in a Korean man. A hairy preauricular free flap is useful for correcting superficial-thickness skin defects of the upper lip, when local and regional flaps a...

An impending macular hole, also known as a stage 1 macular hole, is considered the precur‐ sor to a full thickness idiopathic macular hole. Impending macular holes have a splitting of the inner retina with the clinical appearance of a foveolar cyst or pseudocyst. In some cases, this inner splitting can be associated with a defect in the underlying outer retina (Lee, Kang et al. 2011). An impend...

Three-dimensional integrated circuits (3D ICs) introduce wafer bonding and Through Silicon Vias (TSVs) as new modules, thus extending manufacturing requirements beyond CMOS. A 3D IC with a photosensor is taken as an example to further analyze the resulting new metrology requirements for mass production. For the wafer bond module, data on defects before and after bonding, bond interface adhesion...
