From what I have researched, it seems that the mechanism by which pigment enters the dermal layer when getting a tattoo is:
1) needle dipped in ink punctures skin but ink remains pooled on surface of skin and clean needle enters skin.
2) needle is retracted very quickly and ink that was pooled on surface of skin enters the hole by capillary action. The hole quickly closes, but ink is trapped within the dermal layer still.
What I am wondering is- would this method of administration avoid intra-arterial or intravenous injection of medications?
It seems like it might because even if the needle punctured an artery or vein in the skin, wouldn't there then be an outflow of blood immediately after the needle is withdrawn? And then wouldn't this mean that medication would not flow into the vessel? How could the medication enter a high-pressure system (blood vessel) when it flows into the skin only by capillary action?
Though tattoo needles only penetrate 2mm or less into the skin and only would pierce capillaries, I am also wondering what would happen if longer needles were used that would inevitably piercer larger vessels.
Some medications are unsafe to have enter vessels, so I am wondering if this technique would prevent this...
If this logic is even correct, how could this be proven? What experiment could be conducted to demonstrate this? Thanks for your help.
A male patient came to our observation with the request of a improvement in his jaw-line projection. 6 years ago, he had the installation of 2 mandibular angle hydroxyapatite implants (quadrangular shape, no screw, just scheletrization of the region and implants dropping). During the visit he showed us a CBCT with the perfect ossification of both implants in the lower jaw.
Now the question: which could be the best approach in a possible prevision of a BSSO?
- Implants removal - waiting - then orthognathic surgery
- orthognathic surgery on implants
- nothing, the implants installation it's no compatible with OS
I am doing research with adolescents in Mexico City who have cleft lip and/or cleft palate and want to measure quality of life related to the facial difference. I need a measure that has been validated in Spanish, not just translated into Spanish.
Thank you.

I have done microneedling for 19 years and I always apply vitamin A, C and E to the skin immediately after the treatment. I have never seen a reaction ever and my experience covers about 2000 personal cases and in excess 10,000 when including my associates using the same regime. The product we use is Environ vitamin ACE Oil which has no added preservatives, colourants or perfumes. This is the same oil as used by Zeitter et al in their research at Hannover Medical School to test needling skin at weekly intervals. In their research the vitamin A,C E oil vastly increased the magnitude of the result.
An elderly woman who complained of progressive ulcero-nodular lesion eroding the lower palpebra and the palpebral conjunctiva.. Duration 5 years. No lymph nodes were palpable, hearing was good, no vertigo, no diabetes, mild hypertension was told.

I was asked to confirm or deny the possibility of any connection between mandibular body fractures (mandibular body and angle) caused by a dog in a young boy and mandibular hypoplasia observed many years later. It is required for legal purposes. I cannot find any relevant literature so far.
A 24 year lady has presented with an occult cleft? How does one treat it?
The specific area of fate regeneration I am referring to is the nasolabial folds. Imagine that you have a patient with a bodyfat percentage of 3% and not the typical nasolabial fold patient who has them due to being overweight. The area is very thin and has almost no fat in or around it. The "fold" to be treated is a fine line that is not in the skin but the fat, and the patient is young(as in 21-24). Could injecting prp in the creased area induct fat regeneration? I am talking about permanant results, as in repair or regenerating the fat, not temporarily hiding the lines while your time dwendles until the next injection date. I do not want to plump up the area or use prp as a filler. Do not suggest using fillers as they are an absolute disgrace to science and medicine.

For those of you who don't know, there is a procedure called "SNIF", or sharp-needle-intradermal-fat graft. Here is a video for it, and a link to a pdf that details it in excellent easy detail.

From what I can understand and correct me if I am wrong, the ""SNIF" procedure is basically a dermal filler, not a fat graft. Is this correct? If so, then I have a few other questions.
First, when I see surgeons performing fat grafts into the nasolabial fold area, I see then go in through the upper lip with a cannula. I have given many manual liposuctions with different types of cannulas on the abdomen, and I know that technically, you could access the fat to be lipoaspirated from any point of entry. Of course there are places that are best, but if you had to, you could go in from (almost) anywhere.
IN the pdf, they say that a 23 gauge needle is used for injection. They also directly mention the nasolabial folds. They say that first, they fill it with "traditional lipofilling". What I want to know is, why can't this SNIF replace the "traditional lipofilling" that surgeons usually perform on the nasolabial fold area? Maybe not "replace", but you could graft fat into the nasolabial folds with a 23 gauge needle correct? Not as a filler, but as an actual fat graft that will take as a part of the patients face.
In other words:
Instead of using this snif type needle and point of entry for dermal filling, couldn't you technically graft fat into the nasolabial area (not just a dermal filler) and have that graft take as part of your facial fat?
If you had a patient that was just beginning to get the folds (as in early 20's, just barely visible), couldn't you solve this without going in through the lips? I think the answer is yes. You can access the subcutaneous fat via a 23 gauge needle, there is no need for anything else. I think by using the snif technique, you could do real lipofiling rather than just dermal filling.
I think so. First peer reviewed papers published support this opinion - bringing (cosmetic) surgery to a cellular and even molecular level within the 1.2.3. Dimensional Concept of cause related treatment of the ageing face seems very promising. Looking forward to your opinion.
