Robotic Partial Nephrectomy for Kidney cancer_da vinci robotic surgery

Nephron sparing surgery is the procedure of choice (when ever feasible) in case of localized cancer of kidney. It provides excellent outcomes as compared to Radical Nephrectomy (complete removal of kidney). Preservation of kidney is especially important keeping in mind that many cases are noted where an individual develops tumor later in life in the contralateral kidney whose one kidney was removed earlier (for cancerous or noncancerous reason). In such a situation, previous partial nephrectomy makes a big difference. Robotic partial nephrectomy has advantage compared to open surgery. It avoids long muscle cutting incision and thus result in lesser pain, faster recovery, shorter hospitalization and earlier return to work.

Riboflavin photoactivation by upconversion nanoparticles for cancer treatment

Хирургическая операция

Riboflavin (Rf) is a vitamin and endogenous photosensitizer capable to generate reactive oxygen species (ROS) under UV-blue irradiation and kill cancer cells, which are characterized by the enhanced uptake of Rf. We confirmed its phototoxicity on human breast adenocarcinoma cells SK-BR-3 preincubated with 30-μM Rf and irradiated with ultraviolet light, and proved that such Rf concentrations (60 μM) are attainable in vivo in tumour site by systemic intravascular injection. In order to extend the Rf photosensitization depth in cancer tissue to 6 mm in depth, we purpose-designed core/shell upconversion nanoparticles (UCNPs, NaYF4:Yb3+:Tm3+/NaYF4) capable to convert 2% of the deeply-penetrating excitation at 975 nm to ultraviolet-blue power. This power was expended to photosensitise Rf and kill SK-BR-3 cells preincubated with UCNPs and Rf, where the UCNP-Rf energy transfer was photon-mediated with ~14% Förster process contribution. SK-BR-3 xenograft regression in mice was observed for 50 days, following the Rf-UCNPs peritumoural injection and near-infrared light photodynamic treatment of the lesions.

Ultra-realistic 3D printed organs let Japanese doctors practice real surgery now

In a hospital in Tokyo, doctors were removing two tumors from a patient’s lungs. Meanwhile the students were performing the same surgery but on an artificial lung. If something goes wrong, it doesn’t matter, they can just create another model with a 3D printer.

Professor Toshiaki Morikawa (L) gives a lesson while using a 3D-printed lung at the Jikei University hospital in Tokyo

The ultra-realistic lung — wet, soft, and complete with tumors and blood vessels, will allow surgeons to hone their skills without hurting anyone.

“With the wet model, doctors can experience the softness of organs and see them bleed,” said Tomohiro Kinoshita of Japanese firm Fasotec, creator of the model.

“We aim to help doctors improve their skills with the models,” he added.

The so-called Biotexture Wet Model is created by scanning a real organ in minute detail and creating molds on a 3D printer. That shell is then injected with gel-type synthetic resin to give it a wet, lifelike feeling in the surgeon’s hands. Each one is designed to exactly mimic the texture and weight of a real organ so it can react to the surgical knife in exactly the same way.

According to Maki Sugimoto, a medical doctor who has tried samples, the wet models are almost “too realistic”.

“The touch is similar to that of the real liver,” said Sugimoto, who is also a special instructor at Kobe University Graduate School of Medicine in Kobe, western Japan.

“I suppose that not only young, inexperienced doctors but also experienced doctors can perform a better operation if they can have a rehearsal first,” he said.

Toshiaki Morikawa, a medical doctor at Jikei University Hospital in Tokyo, also said: “The current models are too simple and details of anatomy are not accurately reflected. But this is obviously superior as it’s produced precisely and is very close to the living organ in quality.”

Morikawa expects that one day 3D printing can be used to create functional organs for use in transplants. “Considering future progress in life sciences, I think it is an urgent and significant theme that this outstanding technology should be modified for application to biology,” he said.

How to Stop Bleeding

Bleeding can be anywhere from minor to major. We’ll start with minor. Say you’re with family, friends, or with kids. Someone runs around the house and knocks themself into the corner of a table, and they start to bleed. What do you do?

Wash your hands. Any time there’s a break in the skin there’s a risk for infection. So, get the person to come with you. Wash your hands. Wash off any blood that’s on the person. Then get a clean cloth, a clean towel, even gauze if you have it in your first aid kit, put it on top of where it’s bleeding and hold it there. Put some pressure on it like you’re giving a good firm handshake. Hold it there for as long as you need to. Ten minutes is good.

If this starts to spurt or it doesnt’ stop bleeding after ten minutes you need to get some medical help. You can call 911 to ask what they suggest. You can call the doctor. You can call the instacare. But, really, if it’s spurting or taking more than ten minutes to stop bleeding you need to get some help.

Now, if it’s major, again, if you can, wash your hands. Number two, if it’s big bleeding like that you want to call for help. So, get someone around there to call 911, or if you have your phone with you call 911. Get help as soon as you can.

Next thing you can do if you happen to have anything that can protect your hands, do it. If you just happen to have your first aid kit with you and you have gloves you can wear gloves on your hands. If you happen to have any kind of plastic, plastic bag, or maybe a sandwich bag that you have with you, you can use that to protect your hands as well.

Then you need to find something to stop the bleeding. A cloth. If you have a jacket with you you can use that. The cleaner the better. You want to put pressure on wherever that wound is. Now, if it is an abdomen or there are organs sticking out you don’t want to push those organs back. You don’t want to disturb anything. Just press around it and try to stop the bleeding as best you can.

But, most importantly, keep the person safe, keep yourself safe, keep pressure on the wound, and call for help.
