RESUMEN
Phosphaturic mesenchymal tumors (PMTs) are neoplasms associated with tumor-induced osteomalacia. Patients typically present with pathologic fractures in the setting of chronic hypophosphatemic hyperphosphaturic osteomalacia, as well as gradual muscle weakness, bone pain, and difficulty walking. Because of their rarity and nonspecific symptomatology, phosphaturic mesenchymal tumors often go undiagnosed for years. Even when discovered on imaging, the tumors can be diagnostically challenging for radiologists. Phosphaturic mesenchymal tumors often tend to be small and can be located nearly anywhere in the body, and, therefore, can mimic many other tumors. This case highlights the imaging and pathologic markers of a phosphaturic mesenchymal tumor, often found in a patient with tumor-induced osteomalacia.

OBJECTIVE: Patients who have sustained a stroke suffer from residual motor impairments. Stroke can limit their ability to employ their impaired upper limb properly. Hand function is particularly one of the most frequently persisting consequences of stroke. This paper introduces a new portable hand telerehabilitation platform (PHTP) for home-based personalized treatment of stroke patients. The aims of this study are (1) to document the iterative design and development process of the PHTP, and (2) to explore the therapists' perspectives on implementing home-based treatment of stroke patients. MATERIALS AND METHODS: Local therapists were involved early in designing and developing the PHTP. We collected views of 84 therapists practicing in North America via an online survey. RESULTS: Therapists' perspectives on the introduced prototype support the use of the PHTP to provide home-based telerehabilitation for stroke patients. The System Usability Scale score was 70 for the PHTP, indicating that the platform is usable. The rest of the qualitative results obtained from custom questionnaires showed consistency in the platform design, high perceived usability and good acceptability among the therapists' community. CONCLUSIONS: In sum, the results encourage and support fine-tuning of the PHTP, commercializing it, and conducting prospective clinical studies.
