In this study, we have developed a nanocomposite fibrous scaffold [silica coated nanoHA-gelatin reinforced with electrospun poly(L-lactic acid) (PLLA) nanoyarns] and evaluated its efficacy to promote osseointegration in rabbit mandibular defect in comparison to the scaffold without fibers and commercial nanoHA-collagen graft. For this, critical sized bilateral defect (10 mm length, 3 mm depth and 3 mm width) was created in rabbit mandible and dental implantation was done in two manners. In strategy 1, Ti dental implant was placed along with the scaffold and in strategy 2, the scaffold was implanted for 3 months to ...

ConclusionsLimited diagnostic capabilities and lack of access to eculizumab prevent the implementation of international guidelines for HUS in most developing countries. We propose practice guidelines for India, which will perhaps be applicable to other developing countries.

This study aimed to investigate the effects of recombinant human bone morphogenetic protein (rhBMP-7) on human cancellous bone grafts (BGs) while differentiating between anabolic and catabolic events. Human BGs alone or supplemented with rhBMP-7 were harvested 14  weeks after subcutaneous implantation into NOD/Scid mice, and studied via micro-CT, histomorphometry, immunohistochemistry and flow cytometry. Immunohistochemical staining for human-specific proteins made it possible to differentiate between grafted human bone and newly formed murine bone. Only BG s implanted with rhBMP-7 formed an ossicle containing a funct...

Chronic Achilles tendon ruptures typically are treated with surgical intervention except in low-demand patients or patients who are unable to tolerate surgery. Although several treatment strategies are described, most literature is case reports and case series. There is no widely accepted algorithm or gold standard for surgical treatment of chronic Achilles tendon ruptures. Treatment strategy depends on the size of the tendon gap after excision of nonviable tissue and scar tissue. Smaller gaps can be treated with direct end-to-end repair. Medium-sized gaps can be treated with tendon-lengthening procedures. Tendon transfers...

AbstractThe use of musculoskeletal allografts has become increasingly popular among surgeons. The purpose of this review  is to highlight the procurment and delievery process of fresh osteochondral allografts in the United States. The four distributors of fresh osteochondral allografts in the United States were contacted. Surveys containing quantitative and qualitative sections concerning the procurement and process ing of osteochondral allograft tissue were obtained. Our results showed an average of 13 ± 4.24 years of experience with osteochondral allografts. The average donor age range...

We describe a case of a 43-year-old CMV-seronegative patient who underwent kidney transplantation from a CMV-seropositive donor and developed CMV disease despite valganciclovir prophylaxis. CMV viral load increased even though valgangiclovir dose was augmented and immunosuppressive therapy reduced. CMV genotyping revealed mutations in the viral UL97 protein kinase, explaining ganciclovir-resistant CMV infection. The viral load failed to respond to foscavir, cidofovir and CMV-neutralizing immunoglobulins. Kidney allograft dysfunction developed 3 months post-transplantation with a histopathologic diagnosis of CMV neph...

AbstractPurposeTo present the clinical outcomes and magnetic resonance imaging (MRI) analysis of adjustable cortical suspensory fixation for the femur and tibia in hamstring autograft anterior cruciate ligament reconstruction.MethodsA cohort of 233 sequential patients was analysed for graft failure rate and subjective IKDC, Tegner and Lysholm scores. 144 validated 1-year MRIs assessed and correlated graft healing and tunnel widening.ResultsAt mean follow-up of 28  months ± 8.2 [median 26, range 12–49], the graft failure rate was 4.7%. Significant improvements were seen in all clinical scores (p

This study sought to find the mass of particulate cortico-cancellous bone graft required per 1 cm continuity defect of the mandible. Harvested bone was weighed, milled and maximally compressed in a syringe. The defect length (DL) was measured in centimetres, and the compressed bone volume (CBV) used was recorded. The wet bone mass (WBM) of bone required per centimetre of mandibular defect, and the mass of bone yielding 1cc of compressed bone was calculated. Results were analysed statistically to determine if clinically meaningful differences exist between male and female iliac crest. Forty three patient records were revi...
