Quantification of push-off and collision work during step-to-step transition in amputees walking at self-selected speed: Effect of amputation level.

Maintaining forward walking during human locomotion requires mechanical joint work, mainly provided by the ankle-foot in non-amputees. In lower-limb amputees, their metabolic overconsumption is generally attributed to reduced propulsion. However, it remains unclear how altered walking patterns resulting from amputation affect energy exchange.

Second primary carcinoma arising on a flap: a new primary or a relapse?

Free flaps or pedicle flaps are the mainstay of cancer surgery in the head and neck area. However, their long-term sequelae are still poorly understood. Among these, the development of a secondary primary tumor on a flap is a rare and uncertain reported event.

Submandibular gland involvement in oral cavity squamous cell carcinoma: a retrospective multicenter study.

Background: The submandibular gland (SMG) is routinely excised during neck dissection. Given the importance of the SMG in saliva production, it is important to understand its involvement rate by cancer tissue and the feasibility of its preservation.

Methods: Retrospective data were collected from five academic centers in Europe.

Oral cavity carcinoma in patients with and without a history of lichen planus: A comparative analysis.

Background: Oral potentially malignant disorders (OPMD) are associated with the risk of malignant transformation (MT) into oral cavity carcinoma (OCC). Oral lichen planus (OLP) is one of the most common OPMDs in western countries. Although there is a substantial amount of research on progression to cancer, a specific analysis of the clinical characteristics and prognosis of cancer developed in patients with a history of OLP versus patients without a history of OLP has not been investigated so far.

The potentialities of the Anatomage Table for head and neck pathology: medical education and informed consent.

Introduction: The understanding of anatomy of head and neck region and of the relative pathological conditions may be challenging for most medical students. Furthermore, patients may encounter great difficulties to understand their pathology, the proposed surgical technique, as well as the anatomy of this body district. The purpose of the present study was to present and discuss the use of the Anatomage Table for the assessment of several benign and malignant conditions of head and neck district.
