Sorry Lotte.. :-)

At first I though she could continue on this one, but I decided I want to keep the blog as it is, and Lotte can make her own. In fact, I wasn't ready for the total overhaul of my blog by my wonderful, determined daughter..

So, Please follow Lotte's blog here and share it.

This blog will be available as a resource for us, and anyone else that want to pick our brain. :-)

Loud in the morning..??

This came up on a Facebook group..
 People with CI experiencing loud noise when turning on the CI in the morning, after a long period of inactivity.

Lotte never had this problem.. (See this post from 2007.. Jeezz.. has it been that long....)

But for those who have this experience.. Here is a possible explanation..
Not that I really understand... out of my league.

Dexamethasone released from cochlear implant coatings combined with a protein repellent hydrogel layer inhibits fibroblast proliferation.

Department of Otolaryngology, Hannover Medical School, 30625, Hannover, Germany.

Abstract

The insertion of cochlear implants into the inner ear often causes inflammation and fibrosis inside the scala tympani and thus growth of fibrous tissue on the implant surface. This deposition leads to the loss of function in both electrical and laser-based implants. The design of this study was to realize fibroblast growth inhibition by dexamethasone (Dex) released from the base material of the implant [polydimethylsiloxane (PDMS)]. To prevent cell and protein adhesion, the PDMS was coated with a hydrogel layer [star-shaped polyethylene glycol prepolymer (sPEG)]. Drug release rates were studied over 3 months, and surface characterization was performed. It was observed that the hydrogel slightly smoothened the surface roughened by the Dex crystals. The hydrogel coating reduced and prolonged the release of the drug over several months. Unmodified, sPEG-coated, Dex-loaded, and Dex/sPEG-equipped PDMS filaments were cocultivated in vitro with fluorescent fibroblasts, analyzed by fluorescent microscopy, and quantified by cell counting. Compared to the unmodified PDMS, cell growth on all modified filaments was averagely 95% ±standard deviation (SD) less, while cell growth on the bottom of the culture dishes containing Dex-loaded filaments was reduced by 70% ±SD. Both, Dex and sPEG prevented direct cell growth on the filament surfaces, while drug delivery was maintained for the duration of several months. © 2013 Wiley Periodicals, Inc.

Milestones, Mountain-ranges and views

Milestones....
They happen all the time, and like I have said on the blog.. sometimes they fly by, and sometimes they stand up in your face... (well, I said something to that effect..)

Last Thursday was the yearly checkup for Lotte. A great day out since we (actually, this was the first time I couldn't be there..) have to fly to Oslo, then take a train & tram to the hospital where the center for the check-up is located. One of Lotte's teachers joined Lotte and her mum.

This time, for the first time, it was Lotte who was in charge. She has grown so much lately, that my wife had no problem just sitting back and let Lotte do all the talking. And the specialists were excellent at directing everything to Lotte.
It must have been a wonderful day for Lotte because she was 100% focused the hole time. While adjusting the settings on the CI/BTE's, when finding the noises that she doesn't like (flushing the toilet) and trying to do something with that, she got it, and gave excellent feedback.. While doing speech tests in noisy environments and while doing comprehension tests. she did great. Her teacher was very impressed with Lotte..
But it's a great day out. She loves to go there and thrives on the attention, but this time, at the same time she realises the importance of the day.

In all, this day marks a beginning of Lotte taking over the "CI business" from us. She can accurately give feedback about how and what she hears. She understands the tests they are doing. She understands that there are different programs on her BTE she can use, because she was mentally there when they made them.
Of course life goes back to normal for her as soon as she was back at school, and she won't be playing with the different proframs, but she knows they are there.
Also, with one of her teachers being there, there is someone at school that will recognise difficult situations and can tell Lotte to switch to another program.. or, she might identify that Lotte forgot to switch back to the default setting.

Anyway.. It's a huge milestone. It didn't fly by. We didn't bump into it. It was like the mountain range in the distance that we finally reached.. We knew it was there, and were cruising along towards it. Now, having reached it, we can enjoy the view forward, and back...
It's a great view...

(btw.. Lotes mom promised to post an account of the day as well.... so stay tuned..)

From "L" to "Lotte" - A Reflection

Having Lotte chatting away all day, and of course, us replying to her, and getting her attention by calling out "Lotte"...
Suddenly one realises that the latter was a complete new experience once Lotte began to hear, allmost 3 years ago... (Is it really that long ago - has time passed by that quickly..??)

The sign for her was used of course, but using her sign (Twice the "L" in fingerspelling.) is not used in the same context. Saying "Lotte" is now a way to get her attention. This was not the case with the sign "L - Lotte". When Lotte was deaf, you either had her attention or you had not. One wouldn't "call" her with a sign... Getting her attention would be by waving our hand in her field of vision, or tapping her shoulder.

So, using her name was exhilarating. It signified a new "era" in our - and Lotte's - life.
And nowadays we don't even think about it any more, apart from the sudden realisation that pops up.

As I am writing this, Lotte is upstairs and talking continously, playing different characters, mimicking voices etc.
There is a constant need for sound!
