RESUMEN
We aimed to examine a cohort of patients presenting with breast implant complications to establish the sensitivity and specificity of clinical examination, Ultrasound Scanning (US) and Magnetic Resonance Imaging (MRI) in the diagnosis of implant rupture, and to examine the correlation between US and MRI. We performed a 26-month retrospective review. Patients underwent US and MRI to exclude rupture. Results of US and MRI were compared prospectively for concordance, then retrospectively to clinical findings and surgical diagnosis. Thirty-four patients with 60 implants were reviewed. The sensitivities of clinical diagnosis, US, and MRI for rupture was 42%, 50%, and 83%, respectively, while the specificities were 50%, 90%, and 90%. The concordance between US and MRI was 87%. MRI is the investigation of choice for implant rupture. US is a valuable alternative with good concordance with MRI. When US is positive for implant rupture an MRI is not necessary to confirm the diagnosis. Knowledge of the sensitivity and specificity as well as the concordance between the two investigations is useful to ensure the appropriate use of available resources.

Chronic wounds or ulcers are wounds that do not heal in the usual manner. This type of wound is most common in the elderly and in paraplegic patients with an estimated 1% of the population suffering from leg ulcers and the costs adding up to 4% of the annual National Health Service budget in the U.K. There is an identified need to develop a device capable of remote wound monitoring that enables patients to take charge of their wound management under clinical guidance. A new ¿wound mapping¿ device has been developed, which is based on electrical impedance spectroscopy and involves the multifrequency characterization of the electrical properties of wound tissue under an electrode array. A key feature of the prototype device is the anticipated incorporation of the measuring array into standard commercial occlusive dressings, thereby protecting the wound from interference and contamination, and thus, promoting wound healing, while monitoring the protected wound. Further development is planned including wireless transmission, thus enabling telewound monitoring as described earlier.
