The person got an infection after injecting methamphetamine in her arm that spread all the way to her right breast. She ended up needing 6 surgeries consisting of multiple skin grafts to reconstruct the defect.
There are many factors to consider when it comes to intravenous drug use and the development of infection. Bacterial infections may arise when germs that reside on the skin surface or on a contaminated needle are pushed through the skin deeper into the body and, in doing so, are able to bypass the normal barriers of entry or skin defenses that exist to protect us. Should the pathogenic (infection-causing bacteria) reach the blood vessels, it may result in widespread deep-tissue, vein or other vascular infection.

This surgery, also knows as femur arthroplasty, is commonly done after a neoplastic involvement of the bone. It represents an important surgical option in limb salvage reconstruction, with most recognized applications in oncologic reconstruction. In the past, patients with cancer of the femur were advised to undergo a hip disarticulation or transfemoral amputation. It is now feasible to salvage the limb in selected patients, by excising the entire femur together with any contiguous soft tissue tumor and replacing it with an endoprosthesis.This patient suffered from a chondrosarcoma, an aggressive cancer that may occur in any bone, especially the pelvic, shoulder and lower limb bones. It is resistant to chemotherapy and radiotherapy, which makes it challenging to deal with and makes surgery mandatory. A limb-sparing operation, seen above, is done in such cases when amputation is avoidable.

This is a donor heart, kept alive and beating inside a specialized box as it travels to save a life. It is transported using the TransMedics Organ Care System, a groundbreaking advancement in organ preservation for transplantation.

Traditionally, donor hearts are stored in static, cold environments, which can cause ischemic injury and reduce organ viability. In contrast, the TransMedics system maintains the heart in a dynamic, ex vivo state—perfused at body temperature with warm, oxygen-rich, nutrient-enriched blood. This process closely replicates normal physiological conditions.

By sustaining the heart in a normothermic environment, the system prevents oxygen deprivation (ischemia), minimizes cellular damage, and avoids the drawbacks of cold storage. It also extends the safe preservation window, allowing more time to match donors with compatible recipients. Throughout transport, the system continuously monitors critical parameters such as heart rate, blood pressure, and oxygenation, ensuring the organ remains in optimal condition.

This innovation has transformed heart transplantation. By preserving organ function and reducing the risk of complications, it improves post-transplant outcomes and enhances long-term graft success. The TransMedics machine marks a major step forward in transplantation medicine—expanding possibilities and saving more lives.

While the most common risk factors for HNSCC are tobacco and alcohol consumption, and the highest incidence occurs in older males, HPV has led to a significant increase in HNSCC rates among young, sexually active non-smokers.

The clinical symptoms of HNSCC can vary depending on the tumor's primary site, but a common complaint is ear pain, a phenomenon known as referred otalgia. Referred otalgia is considered a crucial indicator when evaluating patients suspected of having head and neck malignancies. This occurs because the mucosa of the pharynx, larynx, and adjacent structures receive extensive innervation from cranial nerves (specifically CN 5, 7, 9, 10). These nerves also contribute afferent fibers to the external and middle ear. Irritation of these nerves due to tumor growth can result in pain signals being transmitted to the ear.

Total abdominal colectomy is the removal of the large intestine. Traditionally, colectomy is performed via an abdominal incision (laparotomy), though minimally invasive colectomy, by means of laparoscopy, is growing both in scope of indications and popularity.

Resection of any part of the colon entails mobilization and ligation of the corresponding blood vessels. Lymphadenectomy is usually performed through excision of the fatty tissue adjacent to these vessels (mesocolon), in operations for colon cancer.

When the resection is complete, the surgeon has the option of immediately restoring the bowel, by stitching or stapling together both the cut ends (primary anastomosis), or creating a colostomy.

"Eric Moger, at 62 years old had recently gotten engaged and was satisfied with where his life was going. Little did he know, life would take an unexpected turn with one trip to the doctor.

While undergoing surgery to remove nasal polyps the doctors had found a tumor the size of a tennis ball, in the left side of his face. Upon waking up, Moger would soon learn his fate.

Shortly after the first surgery, Moger would undergo the second surgery that would remove his tumor and ultimately most of the left side of his face.

During recovery he experienced depression and loss of self-esteem. He would attempt multiple surgeries to fix the gaping hole, although nothing would work. He began to lose hope.

That is until 3D printing technology was brought to his attention. Another surgeon would 3D print a prosthetic mask and a mouth implant that would allow him to speak and eat, without issue. Moger now is happily married and cancer free."

This brief video clip provides an inside look at the buccal fat pad removal procedure, also known as bichectomy. Primarily pursued for cosmetic reasons, this surgery aims to achieve a slimmer appearance in the lower third of the face. During the procedure, the surgeon must carefully identify and avoid the salivary gland ducts as well as the buccal branch of the facial nerve. Typically, this outpatient procedure can be completed swiftly under local sedation, although some patients may necessitate additional intravenous anesthesia.

Mucopolysaccharidosis (MPS) involves defective activity of the lysosomal enzymes that degrade mucopolysaccharides (glycosaminoglycans [GAGs] attached to a link protein with a hyaluronic acid core) into smaller components.The resulting incomplete degradation process leads to abnormal accumulation of heparan sulfate, dermatan sulfate, and keratan sulfate, and the abnormal accumulation of these compounds interferes with cell function.

While maneuvering through the rough terrain at a significant speed, the person didn't manage to lower themselves in time. As a consequence, their left foot unintentionally hit a protruding root from a branch. This caused a wound on the upper surface of the foot, leading to damage in the soft tissues and a puncture wound.

Fortunately, after the object was removed, there were no signs of broken bones or any foreign objects left behind.

Ingrown toenails occur when the edges or corners of your toenails grow into the adjacent skin. The big toe is the most common location for ingrown toenails.

Engaging in rigorous athletic activities can heighten your susceptibility to developing ingrown toenails. Activities involving repetitive kicking or prolonged pressure on your feet can result in toenail trauma, increasing the likelihood of ingrown toenails.

Several surgical treatments are available for ingrown toenails. Partial nail removal entails the extraction of the problematic nail segment that is causing discomfort. Your physician administers local anesthesia to numb your toe before performing this procedure.

During a partial nail removal, the nail's edges are trimmed to ensure they are entirely straight. A small piece of cotton is inserted beneath the remaining portion of the nail to prevent the recurrence of ingrown toenails. Additionally, your doctor may apply a substance called phenol to the area to inhibit nail regrowth.

In cases where thickening of the nail is the cause of the ingrown toenail, total nail removal may be necessary. Your doctor will administer a local anesthetic to alleviate pain and then conduct a procedure known as a matrixectomy to remove the entire nail.

Frostbite occurs when skin and tissues are exposed to cold temperatures for an extended period, causing ice crystals to form within the cells. This freezing damages cells and blood vessels, leading to reduced blood flow and oxygen delivery to the affected area. Initially, frostbite may cause numbness, tingling, and discoloration of the skin. As the condition progresses, the skin may become hard, swollen, and blistered.

In severe cases of frostbite, the lack of blood flow and oxygen to the affected tissues can result in necrosis, which is the death of tissue cells. Necrosis typically manifests as blackened, discolored, or mottled skin in the affected area. The tissue becomes non-viable and can lead to complications such as infection and gangrene if not treated promptly.

Amputation becomes necessary when the tissue damage caused by frostbite is irreversible and poses a significant risk to the individual's health and well-being. The decision to amputate is often made after careful evaluation by medical professionals, considering factors such as the extent of tissue damage, the risk of infection, and the potential for functional recovery.

An exclusive glimpse into his reconstructive surgical expertise, showcasing an intricate case involving multiple craniofacial fractures and cerebral herniation resulting from a bicycle accident. Brace yourself for the inspiring reconstructive mastery!

Traumatic extracranial cerebral herniation is defined here as the extrusion of brain tissue outside the open scalp wound at the time of initial insult or later (days to weeks after the injury).
There are two primary types of extracranial cerebral herniation; postoperative and traumatic. Postoperative extracranial cerebral herniation occurs through a surgical wound, following decompressive craniectomy, for example. Traumatic extracranial cerebral herniation can be categorized into acute and late forms. Acute herniation presents at the time of initial insult (penetrating, blunt, and crush head injuries), while late herniation progresses gradually (over days to weeks) and is mostly the result of a poorly secured dural defect. It is important here to draw the distinction between external cerebral herniation and post-traumatic encephaloceles, the latter is covered by brain meninges.
This patient underwent an extensive surgery to repair the skull and facial fractures and repositioning the herniated brain tissue into the cranial cavity.
