Ref.: (LML) The utility of the Pressure Specified Sensory Device TM (PSSD) in Hansen's Disease
From: Eric Lee Wan, Ecuador and USA
Dear Pieter,
I am speaking on behalf of our group in the United States. At this time, we would like to share with everyone on LML our recent investigation into the utility of the Pressure Specified Sensory Device TM (PSSD) in Hansen's (see attachment).
The PSSD is a non-invasive and quantitative technique to measure sensory impairment. The PSSD can aid the early detection of leprous neuropathy and has advantages over monofilament and ballpoint-pen testing, as described in our investigation; we have used the PSSD in practice in Ecuador for a decade now.
It is not impossible, nor improbable, for us to imagine how the PSSD can contribute to Dr. Almeida's "cadre of skilled, mobile leprosy workers," who he describes in the most recent LML (September 25, 2015) as those who will be in charge of regular screening of nerves in order to detect early nerve damage and provide interventions promptly.
The PSSD has previously been mentioned in the LML twice: Once on September 5, 2015 in "Infoleps Choice of new (e) publication on leprosy," and more importantly, by Dr. James Wilton on September 10, 2013, when he summarized his experience in Ecuador successfully detecting early Hansen's with the PSSD. He makes reference to another article describing the utility of the PSSD in detecting leprous neuropathy; this article is also attached, along with ours.
We would be happy to answer any questions.
The 2 articles can be cited as:

With warm regards,
Eric
