Effectiveness of an Interdisciplinary Medical Hospital Admission Center: The Role of the Dental Section in the Interdisciplinary System for Perioperative Management of Patients Awaiting Surgery
This study reports on the clinical system and contributions of the systematized, standardized POFM applied through the MHAC. Patients awaiting surgery undergo oral screening before admission, with patients classified into three groups: red, needing surgical oral management (tooth extraction or other oral surgery) before surgery; yellow, needing non-surgical oral management before surgery, due to the planned surgery or the risk of tooth injury in connection with general anesthesia; or green, patients with good oral hygiene considered capable of suitable oral self-management. Patients categorized as red or yellow undergo POF...

An Intelligent Remote Monitoring System for Total Knee Arthroplasty Patients
We describe here an automatic system that performs the monitoring of knee flexion within a domestic environment rather than in a hospital setting. It comprises a master and slave sensor unit that attach using Velcro straps to the thigh and shin above and below the operation wound. The patient performs the prescribed knee exercises whilst wearing the device, during which time it measures and records the angles of knee flexion. The device utilises the Global System for Mobile Communications (GSM) infrastructure to transmit data through the Internet to a secure hospital-based server using an on-board GSM modem. The clinician ...

A De-Identification Pipeline for Ultrasound Medical Images in DICOM Format
AbstractClinical data sharing between healthcare institutions, and between practitioners is often hindered by privacy protection requirements. This problem is critical in collaborative scenarios where data sharing is fundamental for establishing a workflow among parties. The anonymization of patient information burned in DICOM images requires elaborate processes somewhat more complex than simple de-identification of textual information. Usually, before sharing, there is a need for manual removal of specific areas containing sensitive information in the images. In this paper, we present a pipeline for ultrasound medical ima...
