  • Zeb1 promotes corneal neovascularization by regulation of vascular endothelial cell proliferation. [Journal Article]
    Commun Biol. 2020 Jul 03; 3(1):349.Jin L, Zhang Y, … Liu Y
  • Angiogenesis is required for tissue repair; but abnormal angiogenesis or neovascularization (NV) causes diseases in the eye. The avascular status in the cornea is a prerequisite for corneal clarity and thought to be maintained by the equilibrium between proangiogenic and antiangiogenic factors that controls proliferation and migration of vascular endothelial cells (ECs) sprouting from the pericor…
  • Modeling the cornea in 3-dimensions: Current and future perspectives. [Review]
    Exp Eye Res. 2020 Jun 30 [Online ahead of print]McKay TB, Hutcheon AEK, … Karamichos D
  • The cornea is an avascular, transparent ocular tissue that serves as a refractive and protective structure for the eye. Over 90% of the cornea is composed of a collagenous-rich extracellular matrix within the stroma with the other 10% composed by the corneal epithelium and endothelium layers and their corresponding supporting collagen layers (e.g., Bowman's and Descemet's membranes) at the anteri…
  • Total hip arthroplasty after acetabular fracture surgery. [Journal Article]
    Int Orthop. 2020 Jul 02 [Online ahead of print]Milenkovic S, Mitkovic M, … Stojiljković P
  • CONCLUSIONS: THA is a method which gives the best results in the treatment of post-traumatic OA of the hip and AVN of the femoral head after previous osteosynthesis of the acetabular fracture. After THA, life quality and functional status of a patient are significantly improved.
  • Optical coherence tomography angiography analysis of fabry disease. [Journal Article]
    Int Ophthalmol. 2020 Jun 30 [Online ahead of print]Cakmak AI, Atalay E, … Turgut FH
  • CONCLUSIONS: Decreased VD and an enlarged foveal avascular area suggest possible changes in the retinal microvasculature of patients with FD. OCT-A can serve as a useful, noninvasive, quantitative tool for diagnosing FD and monitoring its progression.
  • Extramedullary Motorized Lengthening of the Femur in Young Children. [Journal Article]
    J Pediatr Orthop. 2020 Jun 26 [Online ahead of print]Dahl MT, Morrison SG, … Georgiadis AG
  • CONCLUSIONS: Extramedullary placement of a magnetic expandable intramedullary lengthening nail can achieve lengthening of the femur without the use of external fixation. Considerations with this technique include careful planning of implant length relative to trochanteric-physeal distance, protection against knee subluxation during lengthening, and mitigating deformity of the regenerate. Off-label, extramedullary use of these devices can be considered to decrease the burdens of external fixation in young children. The technique begs the advent of future all-internal technology specifically designed for safe limb lengthening in this age group.
  • Aortic valve: anatomy and structure and the role of vasculature in the degenerative process. [Journal Article]
    Acta Cardiol. 2020 Jun 30 [Online ahead of print]Katsi V, Magkas N, … Tousoulis D
  • Aortic valve stenosis is a degenerative disease affecting increasing number of individuals and characterised by thickening, calcification and fibrosis of the valve resulting in restricted valve motion. Degeneration of the aortic valve is no longer considered a passive deposition of calcium, but an active process that involves certain mechanisms, that is endothelial dysfunction, inflammation, incr…
  • The vascularization of the peroneal tendons: An anatomic study. [Journal Article]
    Foot Ankle Surg. 2020 Jun 15 [Online ahead of print]Mota Gomes T, Guerra-Pinto F, … Oliva XM
  • CONCLUSIONS: Peroneal tendons are well vascularized throughout their course, running through a common vincula, with vascularization provided by various arteries. Avascular areas were observed in the PBT, but none at the PLT.
  • Swept-Source OCT and Swept-Source OCT Angiography before and after Vitrectomy with Stuffing of the Optic Pit. [Journal Article]
    Ophthalmol Retina. 2020 Apr 08 [Online ahead of print]Michalewska Z, Nawrocka Z, Nawrocki J
  • CONCLUSIONS: Stuffing of the optic disc pit with the ILM results in improvement of anatomic and functional results. Prognosis depends on initial morphologic features. Central retinal thickness normalizes faster after surgery in eyes with subretinal fluid when compared with eyes with intraretinal fluid. Faster anatomic improvement does not correlate with improvement of vision. Postoperative increase in the size of the foveal avascular zone in the superficial retinal vessel layer, more pronounced in group 2, may be associated with the prolonged postoperative anatomic recovery in those eyes.
  • The role of external fixation in the management of infected avascular necrosis after traumatic talus fractures. [Journal Article]
    Foot (Edinb). 2019 Oct 24; 44:101644.Engelmann EWM, Wijers O, … Schepers T
  • CONCLUSIONS: Infected talar AVN is a rare condition associated with severe long-term morbidity in term of joint function. The authors recommend extensive debridement and arthrodesis by means of external fixation, followed by post-operative culture-guided antibiotics for the treatment of infected avascular necrosis of traumatic talar fractures. Shared decision-making and expectation management are of crucial importance and may lead to high patient satisfaction despite low functional outcomes.
  • Capitellum fractures: Treatment with headless screws and outcomes. [Journal Article]
    Jt Dis Relat Surg. 2020; 31(2):291-297.Tanrıverdi B, Kural C, Altun S
  • CONCLUSIONS: Capitellum fractures are difficult to diagnose and treat, and good results can only be achieved by an accurate diagnosis, careful surgical technique, and stable fixation. Larger and more comprehensive studies are required to establish a generalization and more accurate inferences on this limitedly studied subject.
  • Hallux sesamoid complex imaging: a practical diagnostic approach. [Review]
    Skeletal Radiol. 2020 Jun 24 [Online ahead of print]Lombard C, Gillet R, … Teixeira PG
  • A wide variety of pathologies can affect the hallux sesamoid complex of the foot, including traumatic, micro traumatic, degenerative, inflammatory, vascular, infectious, and neoplastic conditions. Symptoms are quite nonspecific, mainly related to pain in the plantar surface of the first metatarsal head. In this context, imaging is important for the etiologic diagnosis of hallux sesamoid complex p…
