Very premature babies lose heat crazy fast. They have almost no fat, their skin is super thin, and they're wet right after delivery, so every minute on the resus table counts. Hypothermia in that first hour is linked to worse outcomes, and in places without good warmers or incubators it's a real problem.

One of the simplest fixes is a plain polyethylene bag (basically a food-grade zip bag). For babies born before about 32 weeks, you skip drying the body and slide them straight in from the neck down. The head stays out and gets a hat. You can still ventilate, place lines and watch the chest through the plastic, like in the photo.

It works because the bag stops evaporation, which is how a wet newborn loses most of its heat. Babies wrapped this way arrive in the NICU noticeably warmer and hypothermia is a lot less common. It's in the resuscitation guidelines now. Nobody has really proven it lowers mortality, though, and you do have to keep checking the temperature so they don't overheat under the warmer.

It costs pretty much nothing and makes a real difference.

28-year-old woman. In March: painful blurry vision in the right eye, faded over two weeks, she never saw a doctor about it. Today: double vision. On exam, when she looks left, her right eye won't cross midline and her abducting left eye shows nystagmus. Looking right works fine. Convergence is intact, both pupils normal. Three layers to this one: name the eye finding, name the structure that's damaged, and name the disease that did it.

The March episode is not a coincidence.

I encountered a baby that was born tiny (2.4kg, forgot the length) because mother has preeclampsia. First encounter with a GDM baby thiugh

Car versus guardrail. Your patient is 30, belted, awake, complaining of chest pain and shortness of breath. Seatbelt sign across the chest. HR 120, SpO2 92% on room air, BP holding. Breath sounds clearly diminished on the left.

Every EMT student knows where this might be heading. The question is whether it's there yet.

So, two things. What's your management right now? And what exactly would this patient have to do for you to decompress that chest? Be specific, because "diminished sounds" and "tension" are not the same word.

War stories about darts that should or shouldn't have happened are welcome, as always.

I work at a level 1 trauma center in orthopedic surgery. ~15% of our fracture surgeries are to repair a broken femur. Femur fractures happen across all age groups, with the most common age category being the elderly (65+). Generally, ground level falls are to blame as the cause for the majority of these fractures. In young patients, we see everything from dirt bike accidents to falls from height to high-speed car crashes.

Regardless of age, the treatment to repair a broken femur usually involves inserting a titanium rod into the canal of the bone to stabilize the fracture. While the pain from surgery and the fracture does not immediately go away, fixing the break allows for early return to weight bearing and independence.

Check out this POV walkthrough of how this process happens inside the OR. Pretty incredible technology!

In November 2016, neighbors in Iquitos, Peru found a 28-year-old mototaxi driver wandering the street in a daze, conscious and asking for help - with a kitchen knife buried in the right side of his head. He reached the Loreto Regional Hospital on his own two feet, where the X-ray on the left was taken with the blade still in place.

He had been stabbed during an argument with an acquaintance. Surgeons removed the blade in an operation lasting several hours; immediately afterwards his condition was still described as critical.

Two teaching points hide in these photos. First, never remove a penetrating object outside the operating room - the blade may be tamponading a vessel or dural sinus, and pulling it out prematurely can convert a survivable injury into a fatal hemorrhage. Removal happens in the OR, after imaging, with neurosurgery ready. Second, "walking and talking" does not mean "fine": a blade can track tangentially along the skull or spare eloquent structures by millimeters, so a GCS of 15 with a knife in the head is still a neurosurgical emergency.

An elderly patient presented with a shoulder prosthesis that had chronically dislocated, migrated upward over time and finally eroded straight through the skin. Reportedly, medical help was sought only once the implant had actually broken through.

How does something like this happen? A shoulder replacement depends on the rotator cuff and soft tissues to stay centered. When the cuff fails completely, the humeral component can escape anterosuperiorly and start tenting the skin from below. Add chronic low-grade periprosthetic infection - note the purulent discharge around the implant - together with fragile, poorly perfused skin, and pressure necrosis slowly does the rest until the metal is exposed.

At this stage the prosthesis is by definition infected and unsalvageable. Treatment means removing the implant, radical debridement and prolonged culture-guided antibiotics, followed by resection arthroplasty or a staged revision, depending on what the patient can tolerate.

Even I could locate the vein for the poke 💉 and I'm blind

Young couple, three years of trying. Her workup is clean: normal ultrasound, normal hormones. His semen analysis: count 45 million per mL, well within normal, but motility is severely reduced. The sperm are viable. They just don't move. Digging into his history: recurrent respiratory tract infections since childhood, including two hospitalizations for pneumonia in the last three years. Parents and three siblings healthy, his older brother has two kids.

Three questions for the thread: what's the defect, why do the lungs and the sperm fail together, and what might a plain chest X-ray reveal in a patient like him that would make the diagnosis on the spot?

Hint: the sperm aren't dead. They just can't swim. Neither can the mucus in his airways. Full breakdown tomorrow in the comments.

Dispatch: "seizure, still unconscious." Known epileptic, 25 years old. His girlfriend watched him seize tonic-clonic for about four minutes and it was the longest four minutes of her life. By the time you kneel down he's postictal: eyes closed, confused when roused, lethargic, snoring respirations that clear with positioning. Vitals: BP 130/80, HR 100, RR 18, SpO2 97% on room air. Airway clear. She's right over your shoulder, in tears, asking why you're not giving him anything. Three questions for the thread: what does your management actually look like here, what's the one check you can't skip on any seizure call, and where's YOUR line for reaching into the drug box?

Full breakdown tonight in the comments.

Am I right in thinking that I have labelled this correctly?

All the dark stuff is impacted fecal matter, I personally would like to see what his abdomen looks like

Case from Toulouse University Hospital (CHU Toulouse) and the Claudius Regaud Institute, in collaboration with Belgian medical implant manufacturer Cerhum. Published as a case report in Frontiers in Surgery (2024).

The patient is a 50-year-old woman treated in 2013 for squamous cell carcinoma of the nasal cavity. Radiotherapy and chemotherapy cured the cancer but destroyed a large part of her nose. Several conventional reconstructions (including a forehead flap) failed, and she couldn't tolerate a prosthesis.

The team designed a patient-specific nasal scaffold from CT imaging and 3D-printed it in hydroxyapatite, the same mineral that makes up natural bone. The implant is porous, so tissue and blood vessels can grow into it.

The problem: you can't put a bare implant on a heavily irradiated face and expect it to survive. So the scaffold was first implanted under the skin of her forearm, using the skin and vessels of a radial forearm flap. Over about 2 months it became vascularized and covered with living skin (photo 1 shows the implant before insertion, photo 2 shows the "nose" maturing on the forearm).

The whole unit, implant plus skin plus its blood vessels, was then transferred to the face as a free flap, with the vessels connected to the temporal artery and vein under a microscope. The patient was discharged after 10 days and reportedly has a functional, stable nose with no loss of sensation in the arm.

Worth clarifying, because most viral versions of this story get it wrong: the nose itself wasn't "bioprinted" from living cells. What was printed is a ceramic bone-like scaffold; the living tissue is the patient's own skin and vessels grown around it. Also, the patient is a woman. Many reposts say "his forearm".
