Insert 7 - chimney sweep
The new stove needs a flue pipe of 18cm diameter, the existing galvanized steel pipe is 20cm. We'll insert a new inox 18 cm pipe into the 20cm existing pipe. Before that the old pipe needs cleaning: sweeping. I guess it's never been done before.
Bought a chimney sweeping set on a certain online store, €30, consisting of a brush, and 12 flexible rods that you can attach to eachother, to use it to clean the chimney, rotating the brush using an electric drill.
Closed the pipe off at the bottom with a very strong bag. You really don't want soot in your house. And so don't we. It's not a little, I think the bag contains about 550 g dirt.

Insert 6 - Metalfire Optimum - enclosure partly demolition
The old stove needs removing to make room for the new one. Very important: what size pipe is the chimney channel? The Metalfire needs an 18 cm diameter flue pipe, the existing channel is a 20 cm galvanized pipe. Two problems: 20 cm is too wide, and galvanized steel is not suitable as a flue pipe.
The engineer hopes there is a second tube inside this 20 cm one, that is 18 cm. 15 cm would be trouble. (15, 18 and 20 are standard sizes)
As it was...
Take the front of the enclosure off:
Removed the old stove, there is a raised platform there, ladrillo and cement:
Brittle cement, pebbles, and thus a hole in the floor:
The chimney flue pipe is a single 20 cm pipe, galvanized steel. Rubbish!
Fill the gap in the floor with cement for an even level floor:
Leftover bits:
Oooh!

ON and off (part 11)
Vision goes down and up a little, just to be sure the inflammation in the eye has not returned: back to Urgencias 🙄.
This time a doctor at urgencias who seems to be more experienced with eyes, she looked into the eye herself, and said there was no inflammation, and she would call Oftalmologia. She spoke with one of them, and said: you have chronic optic neuritis, you are on Nurane, capsules with ginkgo leaf extract + magnesium, which has vasodilatory properties to stimulate nerve repair, it is well possible what you experience is due to Nurane. There will be good and there will be worse days.
Well, the good news is that there is no inflammation, but the "chronic" bit is really not good news. New appointment with Oftalmologia for revision, OCT scan and field of vision. The OCT scan shows that indeed part of the optic nerve is no longer functioning. This means 40% of vision in the left eye has gone, and won't come back. General vision is still ok, as the missing bits are missing, they are not colored or flashing, and missing bits are filled in from the right eye. However, at the moment this condition is tiring, as it sort of feels like you have new glasses with a strong reading part. And, reading with only the left eye is not possible any more.
Read a fellow patient idea: close your eyes, and sit in the sun. It helped her. Who knows.
(ON stands for Optic Neuritis.)

Insert 5 - Metalfire Optimum - arrived
In Metalfire Optimum you can read about engineer Jansen's lust for a Metalfire Optimum insert wood stove. After much deliberation an Optimum 700 was ordered, and it has arrived. The delivery service did not have a cart to lift the pallet up 10 cm, so they could not lift it up to the porch in front of the front door, which is 10 cm above street level. So, it was left outside, next to the porch, at street level.
Grmbll. What to do.
Engineer Jansen decided to buy coaster wheels that can carry this 200 kg heavy piece of equipment, and use some steel profiles to devise sort of a cart. The wheels can carry 650 kg divided among 4.
Well, it may look easy, but it cost all day, and given the engineer's condition it was rather exhausting.
1. Move the pallet
Wheels attached, such that when the bolts are screwed into the pallet the pallet is lifted a centimeter above the ground, resting on the wheels:
2. Now remove the stove from the pallet:
Screws!
Well, that was the theory. The stove is placed on two wooden beams, but those beams are screwed onto the pallet with 4 long screws. The points of those screws were bent, as the cart they used bent them. So, engineer Jansen could not unscrew them. Bending the screws back did not work, not enough room. Drilling the head of the screws off did not work either, it has cost the engineer one of his drill bits. Could not saw off the ends of the screws either.
Decided to drill holes around the screws, and force lift the beams off of the pallet, then use the iron saw to saw through the screws. That worked.
3. Inside!

Engineer Jansen calculates drips and avoids mansplaining (part 10)
The (precautional) second course of antibiotics now runs almost 1.5 weeks, so 5.5 weeks antibiotics in total, 1.5 weeks still to go. Last week another round of blood was extracted from the engineer, to see if Borrelia (Lyme) can now be detected (no), and to see if IGM toxoplasmosis is positive, meaning an active infection with that (no). Good.
The past few days engineer noticed a slight degradation in vision in the left eye, like there was a slight mist, so back to Urgencias, again. Passing on to OftalmologÃa did not take long. Fortunately the doctor that knows the whole history. Off to puerta 5 for CV test (campo visual, field of vision). The engineer thought the upper half of his eye sight had degraded, the doctor saw in the results that the lower half had deteriorated.
Thinking about that, the engineer thinks that both she and he are correct. The whole field of vision has slightly deteriorated, meaning the lower half indeed got worse. But the upper half too. Only, the machine does not detect that because the engineer could still see those small light flashes through the mist.
[Field of Vision test: the inside of a 40 cm white hollow half globe is in front of your eye, then randomly displays tiny white flashes in random places on the inside surface, and you must press a button when you see the flash. So they know if parts of your vision are missing.]
![]() |
Anyway. Look into the eyes: we see no inflammation activity (good!). That was a relief, because one of the engineers’ worries was that the inflammation was back. That can happen if it’s not Lyme after all, but something else, like an autoimmune thing, a fungus, …
So far the cause is undetermined. Lyme, toxoplasmosis, rick-ettsia (ha ha ha) all negative, according to last week’s serologia. That is good too. (Lyme and rickettsia both are tick borne diseases.) A negative lyme test does not mean much, nor does it when positive, as they are insensitive and indecisive.]
Losing one eye is bad enough, the other eye may not go down that path (please), that would be catastrophic, hence this repeated visit to Oftalmologia via Urgencias.

Mansplaining in the Sala de Sillones

Toxoplasmosis or no? (part 8)
Reading up on the appointments in the Andalucia Salud app the engineer encountered the report of a serologia analysis. Interested as he is the engineer studied it.
Attentive readers will remember that extracting blood from the engineer went rather chaotically, not the engineer's fault, of course. Saturday 16/8 a vial was taken to detect Lyme/borrelia, Monday 18/8 the engineer was called back to the hospital in the evening because "they did not have enough", no one knew how or what, and two vials were extracted at the request of the engineer, and to determine later what to do with them. Tuesday 19/8 was a revision appointment at oftalmologia, that evening they called that the engineer was to present himself at the Sala de Extracciones, without breakfast. 6 vials were taken. Bloody vampires!
Informe serologia, AST, IGG, IGM
IgG, IgM
Ocular Toxoplasmosis
Yes, toxoplasmosis can affect the eyes, and the symptoms can be quite what the engineer has.
Toxoplasmosis is not a bacteria, it's a one celled critter that is difficult to eradicate, not sensitive to antibiotics, and can go in hiding in cysts, also in the eye, and resurface after many many years. 10-20 or more years. Not good news.
You get toxoplasmosis from cat scratches, especially from kittens, cat poop, eating raw meat that is contaminated with the cysts, eating (raw) vegetables that are contaminated in the field, or by contacting contaminated soil.
The engineer is not a cat lover, due to allergies, and avoids cats. Nor is he an avid raw-meat eater, being semi vegetarian. Raw vegetables: well.. yes! Lettuce comes washed, radishes, too.
AAAAARGHHH!
Jensen Test
Urgencias (again)
Another visit to Urgencias, to see if any of the other blood tests has a complete analysis of IgM. Passed on to Oftalmologia again, as they cannot access the serologia report of the other two blood extractions at Urgencias.
Not the eye doctor who ordered the serologia:
"You don't have toxoplasmosis"
"But the symptoms..."
"You don't have toxoplasmosis, you have optic neuritis"
Enfermeria
Rationale
More vision loss and no sinusitis (part 7)
25/8 What next
11/9
11/9 OtorringologÃa
Exactly like this. With sections so they know how far down the engineer's substantial nose they are. She spelunked down one side, and then the other side. Nothing interesting apparently. No treatment. Although the medical status suddenly has a nasal spray with corticoides. And she wants me to wash my nasal cavities with salty water with a special bottle. Hm. The engineer is not ecstatic about that prospect.
11/9 Urgencias, again, directly after OtorringologÃa
Yes, your vision has deteriorated. We'll make an appointment with Neurologia in Almeria. Continue with the antibiotics.

PURPLE?? (part 6)
Angiogram with contrast
Angiogram. First thought they wanted to draw more blood (these people must be vampires!), but no, it is an eye scan with a dye for contrast to visualize the arteries. Not the elusive gadolinium this time, but a bright purple substance.
Puerta 8 for the preparation. The engineer about now knows how this goes, first the machine to measure your eye, and make you read the letters. He asked for the eye drop himself, to avoid them thinking of this after half an hour, administering the drop, and having to wait yet another half an hour, giving them the chance to lose track.
The angiogram machine. Needle inserted into the engineer. A vial with purple stuff on the table.
"Si!"
By 14:00, doctor appeared.
"Serologia all negative"
"MRI all good"
Unique!
"Lyme ON is an exceedingly rare ocular manifestation of Lyme disease (LD) and only a few cases have been published in the literature. Lyme ON is very rare but should be included in the differential diagnosis in unexplained cases, particularly in Lyme endemic areas."

GADOLINIUM??? (part 5)
It's a good thing we dropped by RadiologÃa on Friday for information on how and what, because the MRI is at 12:30, but you can not have breakfast. Or, nothing after 08:00. The clever engineer prepared a muesli breakfast the night before, set his alarm to 06:00, and survived that part of the ordeal.
Gadolinium
They make you sign a waiver, especially for the contrast dye. "Gadolinium" it said in the papers. Gadolinium? That's a rare earth metal. What..?
Apparently gadolinium is the most paramagnetic substance on Earth, and is used as a contrast dye in MRI imaging.
Still, eh.. gadolinium? Wiki has this to say:
"Gadolinium(III) ions in water-soluble salts are highly toxic to mammals."
ow. The engineer definitely IS a mammal, despite everything.
“However, chelated gadolinium(III) compounds prevent the gadolinium(III) from being exposed to the organism, and the majority is excreted by healthy[9] kidneys before it can deposit in tissues. Because of its paramagnetic properties, solutions of chelated organicgadolinium complexes are used as intravenously administered gadolinium-based MRI contrast agents in medical magnetic resonance imaging.”
That's all good, then.
Wait what is this “majority” that is excreted?? What about the rest?
MRI
The RM (Resonancia Magnetica) is located in the cellar, down 1 floor, very atmospheric dungeon.
The waiver I had received apparently has a list of questions, but was printed so small that it was not legible for the engineer's current state of his eyes. Nor for the other engineer's state of his eyes. It's a list about metal in your body, and if you work in a metal workshop, if you have piercings, pacemakers, implants, etc. No, and his piercings the engineer already removed, as he's not that daft.
You have to undress, only keep your underpants on. The engineer had expected that and was prepared. And he had to wear a negligee. (ooh!)
It's a huge machine, big vertical ring, with a plank that you have to lay down on. Bzzz! Into the machine, with a needle in his arm. No idea what they connected, or what the gadolinium looks like. Fantasised about bright green, or purple. Probably just colorless.
Cage over your head, a squeeze ball switch to alarm the technians in case you get unwell, pads next to your ears, to dampen the noise and fix your head in place.
"Can you say now and then how many more minutes?" (it was supposed to be sort of 20 minutes)
"Just relax"
Well and noise it makes. A whole symphony of sirens, clicks, sawing machines, drills, whooping sounds, drones, ... Some parts were like a bad house track, some parts were almost Kraftwerk.
The engineer just stared up at a text on the cage he could not read. What do you do, can you breathe normally? Can I move my eyes? Better not. There are two minute holes, with a prism, so you can see the ring of the machine, and the technicians walking by. Not much for them to do, but watch engineer Jansen.
And engineer Jansen just stared up. The arm with the needle started to get stiff. Aha, they are administering the contrast now, apparently.
On and on... drone, click, BZZ...
Started counting the "sweeps"
Lost count.
"This must be another 5 minutes"
"Or 2?"
“15?"
And how many times have I thought that?
Lost count.
Aargh, a beginning itch. Ignore ignore ignore!
They could have sedated the engineer, if the engineer was not such an adversary towards sedation.
How long is a minute, actually?
Well, inside an MRI machine time is different.
Just concentrate on staring up, and breathing slowly.
I dared flex one finger of the hurting arm, making sure the head stayed still.
..
"Ready!"
The noise stopped and plank rolled out of the machine.
"Careful, you may feel slightly dizzy"
Slightly dizzy was a bit of an understatement, they needed to support the engineer walking back to the changing closet.
Let's ask dr. Google (Ad Interim) for an explanation:
Even read somewhere that the better your vestibular system is, the dizzier you are.
Well, the engineer has a very healthy vestibular system.
The engineer sat on the chair a few minutes before taking off the negligee (ooh!), and be taken home.

The engineer researches optical nerve inflammation and optical discs, and finds Lyme (part 3)
- With an inflamed optical nerve you usually have a headache when moving your eyes, I did not;
- Inflamed optical disc: “unilateral presentation is extremely rare”. I have that.
- Inflamed optical nerves are often caused by things like MS. That is: people with MS often have an inflamed optical nerve. I’m too old to start having MS, I think. The target group is women 20-40 years old. The engineer definitely is not that. (See impressive hairy chest photo in blog before previous blog.)
- “Unilateral papilledema can suggest a disease in the eye itself”. Well, Lyme quite possibly.

Detective Eminent Doctor Engineer Jansen-Watson (part 2)
Also he remembered the phone conversation the doctor had with the neurologist, after the CT scan.
"No headaches?"
"No"
I could sense their suprise. (Many people witn affected optical nerves experience pain when moving their eyes.)
The engineer researches optical nerve inflammation and optical discs, and finds Lyme
Reading up on optical nerve inflammation and optical discs:
The oftalmologist suspected: inflamed optical nerve, or Optic Neuritis, and prescribed the 3 days of 1 g prednisolone per day, intravenously. That is a wellknown treatment, to preserve the optical nerve prior to treating the cause.
After the CT scan the "efermedad actual" is: Papiledema, swelling of the optical disc (very typical for an engineer to have, an optic disc), which has a different course of treatment.
Let's ask dr. Google AI, I guess that is dr. Google Ad Interim? Must be him (or her):
- With an inflamed optical nerve you usually have a headache when moving your eyes, I did not;
- Inflamed optical disc: “unilateral presentation is extremely rare”. I have that.
- Inflamed optical nerves are often caused by things like MS. That is: people with MS often have an inflamed optical nerve. I’m too old to start having MS, I think. The target group is women 20-40 years old. The engineer definitely is not that. (See impressive hairy chest photo in previous blog.)
- “Unilateral papilledema can suggest a disease in the eye itself”.
Elementary dr. Watson
- The "enfermedad actual" now is not neuritis optica but papiledema.
- I think they established that after the CT scan, in that phone conversation with the neurologist, because the optical nerve may not be affected.
- They decided to give 40 mg prednisolone in the bum.
- The paper still had 1 gram prednisolone per day, as prescribed by the ophthalmologist
- But, the ophthalmologist was never informed of the new "enfermedad actual'.
- The day after the CT scan, first day 1 gram treatment was a holiday, so oftalmologia was closed, and they did not communicate about engineer Jansen
- It now is the weekend, so no ophthalmologist around to discuss.
- And so they never changed or deleted the 1 gram per day.
- They blindly follow what is on the paper.
- Every step has another person, and they make mistakes because they don't think.
- Luckily Engineer Jansen still has a brain.
So there was dr. engineer Jansen in the chair awaiting the needle, but asked if he could discuss.
"Patiente acude para continuar con tratamiento de prednisolona 1 gram (era dosis) refere que no quiere poneria hasta hablar con oftalmologia porque no considera tener edema papilloma"
or:
"Patient comes to continue treatment with 1 gram of prednisolone (was the dose) and says he does not want to put it until he speaks with an ophthalmologist because he does not consider having papilloma edema."
I don't have neuritis optica, I do have edema, and I don't need 1 gram for that.
I'm apalled. I understand now how medical mistakes come to be.
