Angiofibroma celular de vulva: una entidad a investigar

Cellular angiofibroma of the vulva is a well-circumscribed tumor that occurs in men and women. This tumor has histological and immunohistochemical features that distinguish it from other vulvar tumors. The prognosis is good, although there is a risk of recurrence. We report the case of a woman with this diagnosis.     

Robotic Rehabilitation and Spinal Cord Injury: a Narrative Review

Mobility after spinal cord injury (SCI) is among the top goals of recovery and improvement in quality of life. Those with tetraplegia rank hand function as the most important area of recovery in their lives, and those with paraplegia, walking. Without hand function, emphasis in rehabilitation is placed on accessing one’s environment through technology. However, there is still much reliance on caretakers for many activities of daily living. For those with paraplegia, if incomplete, orthoses exist to augment walking function, but they require a significant amount of baseline strength and significant energy expenditure to use. Options for those with motor complete paraplegia have traditionally been limited to the wheelchair. While wheelchairs provide a modified level of independence, wheelchair users continue to face difficulties in access and mobility. In the past decade, research in SCI rehabilitation has expanded to include external motorized or robotic devices that initiate or augment movement. These robotic devices are used with 2 goals: to enhance recovery through repetitive, functional movement and increased neural plasticity and to act as a mobility aid beyond orthoses and wheelchairs. In addition, lower extremity exoskeletons have been shown to provide benefits to the secondary medical conditions after SCI such as pain, spasticity, decreased bone density, and neurogenic bowel. In this review, we discuss advances in robot-guided rehabilitation after SCI for the upper and lower extremities, as well as potential adjuncts to robotics.     

Effects of occlusal forces on the peri‐implant‐bone interface stability

The occlusal forces and their influence on the initiation of peri‐implant bone loss or their relationship with peri‐implantitis have created discussion during the past 30 years given the discrepancies observed in clinical, animal, and finite element analysis studies. Beyond these contradictions, in the case of an osseointegrated implant, the occlusal forces can influence the implant‐bone interface and the cells responsible for the bone remodeling in different ways that may result in the maintenance or loss of the osseointegration. This comprehensive review focuses on the information available about the forces transmitted through the implant‐crown system to the implant‐bone interface and the mechano‐transduction phenomena responsible for the bone cells’ behavior and their interactions. Knowledge of the basic molecular biology of the peri‐implant bone would help clinicians to understand the complex phenomenon of occlusal forces and their effects on the implant‐bone interface, and would allow better control of the negative effects of mechanical stresses, leading to therapy with fewer risks and complications.
