The corticoperiosteal medial femoral supracondylar flap: anatomical study for clinical evaluation in mandibular osteoradionecrosis.

Purpose: An ideal way to treat osteoradionecrosis of the jaws is to transfer an osteogenic, appropriately vascularized flap to the affected site. The corticoperiosteal femoral medial supracondylar flap is being used increasingly in the treatment of complex pseudarthrosis of long bones, but is yet to find robust indications for use in the treatment of osteoradionecrosis of the jaw, the reasons being a lack of anatomical data concerning its vascular supply and the local constraints of its routine harvest. This study presents an anatomical study and literature review to explore its potentials in clinical practice.

Changes in surgical consent practices for common otolaryngology procedures: impact of Modernising Medical Careers.

Objectives: To assess elective surgery consent practices amongst senior house officers from a selection of UK ENT departments, and to compare results with similar surveys in 2002 and 2005.

Methods: A telephone survey of senior house officers in 40 UK ENT departments was conducted to assess departmental consent policies and knowledge of complications of common ENT operations.

Results: A total of 77.

Branching patterns for arterioles and venules of the human cerebral cortex.

Branching patterns of microvascular networks influence vascular resistance and allow control of peripheral flow distribution. The aim of this paper was to analyze these branching patterns in human cerebral cortex. Digital three-dimensional images of the microvascular network were obtained from thick sections of India ink-injected human brain by confocal laser microscopy covering a large zone of secondary cortex.

Improving prediction of malignancy of cytologically indeterminate thyroid nodules.

Background: Fine-needle aspiration (FNA) is essential in the investigation of thyroid nodules. The British Thyroid Association guidelines recommend clarification of whether follicular nodules are probable follicular neoplasms that require surgical excision. This study assessed the value of the subclassification of cytologically indeterminate thyroid nodules into either follicular neoplasms or other pathology.

Scaling laws for branching vessels of human cerebral cortex.

Objective: Vascular architecture, particularly of cerebral microvessels, has profound implications for both health and disease in a variety of areas, such as neuroimaging, angiogenesis and development, Alzheimer's disease, and vascular tumors. We analyzed the architecture of tree-like vessels of the human cerebral cortex.

Methods: Digital three-dimensional images of the microvascular network were obtained from thick sections of India ink-injected human brain by confocal laser microscopy covering a large zone of secondary cortex.
