Glad you found us! I'm guessing, being in Florida, that your student's primary language might be Spanish? There are a couple of people that post on this board who speak Spanish as their primary language. Also, many of FIRST's publications are available in Spanish. If you contact FIRST's office at 215-631-1411, they can give you more information and get something mailed out to you.
As far as odor, it depends partly on what type of ichthyosis this boy has. Some forms of ichthyosis are associated with odor problems more than others (though almost all forms have at least a slight odor to them). The odor is frequently caused by infection (an easy secondary problem with so much cracking, dry skin). Bathing with a little bleach in the bathwater is sometimes all that's needed...but if it's truly an infection, oral antibiotics may be necessary to really control the infection (and hence the odor). Again, FIRST has some great material that describe how to deal with this.
Please let us know if we can help provide you with any other information, or if you have any other questions about ichthyosis.
