Hip abductor defect repair by means of a vastus lateralis muscle shift

Scarring or detachment of the hip abductors, particularly of the gluteus medius, from their insertion may lead to severe abductor weakness, recurrent dislocations, pain, and diminished quality of life. We performed a retrospective study to evaluate whether vastus lateralis shift is associated with satisfactory results and low rate of complications. Eleven adults underwent vastus lateralis shift to bridge a well-documented abductor muscles' insertion defect. Preoperative and postoperative hip functions were assessed applying the Merle d'Aubigne score, British Medical Council scale, and Visual Analog Scale. Significant postoperative improvement was noted in mean Merle d'Aubigne score, gluteus medius muscle force, and quality of life. Vastus lateralis shift represents a viable treatment option for hip abductor deficiency, significantly improving abductor strength and overall quality of life.

Advanced reconstructive technologies for periodontal tissue repair

Reconstructive therapies to promote the regeneration of lost periodontal support have been investigated through both preclinical and clinical studies. Advanced regenerative technologies using new barrier-membrane techniques, cell-growth-stimulating proteins or gene-delivery applications have entered the clinical arena. Wound-healing approaches using growth factors to target the restoration of tooth-supporting bone, periodontal ligament and cementum are shown to significantly advance the field of periodontal-regenerative medicine. Topical delivery of growth factors, such as platelet-derived growth factor, fibroblast growth factor or bone morphogenetic proteins, to periodontal wounds has demonstrated promising results. Future directions in the delivery of growth factors or other signaling models involve the development of innovative scaffolding matrices, cell therapy and gene transfer, and these issues are discussed in this paper.

What makes the difference between the natural course of a remaining type B dissection after type A repair and a primary type B aortic dissection?

To analyse the outcome and need for intervention [surgery or thoracic endovascular aortic repair (TEVAR)] in patients after surgery for remaining type B dissection after type A repair and primary type B aortic dissection.

Prognostic impact of β-2-microglobulin expression in colorectal cancers stratified by mismatch repair status

β-2-microglobulin (B2M) is essential for antigen presentation, yet may also possess proto-oncogenic properties.

Thoracic endovascular aortic repair as emergency therapy despite suspected aortic infection

To evaluate thoracic endovascular aortic repair (TEVAR) as emergency therapy despite suspected aortic infection.

Mechanisms of symptomatic spinal cord ischemia after TEVAR: insights from the European Registry of Endovascular Aortic Repair Complications (EuREC)

To test the hypothesis that simultaneous closure of at least 2 independent vascular territories supplying the spinal cord and/or prolonged hypotension may be associated with symptomatic spinal cord ischemia (SCI) after thoracic endovascular aortic repair (TEVAR).

Repair of stent graft-induced retrograde type A aortic dissection using the E-vita open prosthesis

Stent graft-induced retrograde type A dissection is a life-threatening complication after endovascular treatment of acute aortic type B dissections.

Use of a painless external fixator for unilateral mandibular fracture repair in nine equids

OBJECTIVE: To report use of a pinless external fixator (PEF) for unilateral mandibular fractures in 9 equids. STUDY DESIGN: Case series. ANIMALS: Equids (n=9) with unilateral mandibular fractures. METHODS: All fractures were stabilized with the AO/ASIF PEF using a minimum of 4 clamps, under general anesthesia. Fracture configuration, complications, outcome, and owner satisfaction were evaluated. RESULTS: All fractures were stabilized; 2 equids were euthanatized; 1 because of an inability to stand after surgery and 1 because of owner decision after PEF dislodgement. Seven repairs healed with good outcome and owner satisfaction. Complications included dislodgement of the PEF (3), bone sequestration (3), and weight loss (1). Drainage associated with repair resolved after removal of sequestra and clamps. CONCLUSIONS: Stabilization of unilateral mandibular fractures with the PEF in horses was minimally invasive with minimal risk of tooth root interference; however, after care is time consuming. CLINICAL RELEVANCE: PEF is an alternative technique for stabilizing unilateral mandibular fractures in equids.

Incidence of descending aortic pathology and evaluation of the impact of thoracic endovascular aortic repair: a population-based study in England and Wales from 1999 to 2010

To investigate population trends in thoracic aortic disease (dissections and aneurysms) in England and Wales, with focus on the impact of thoracic endovascular aortic repair on procedure numbers and age at repair.
