Acute compartment syndrome refers to ischemic tissue damage secondary to elevated pressures in the enclosed compartments of the lower legs or forearm. When the tissue pressure in an enclosed compartment exceeds the perfusion pressure, the resulting diminished tissue perfusion and compromised blood flow to the muscles and nerves inevitably lead to ischemic tissue necrosis. Majority of the cases involving the lower extremities are due to a traumatic event, most commonly tibial fractures. Other causes include a crush injury or other long bone fractures in a motor vehicle accident, a tight cast or dressing after trauma, and drug overdose.
Porcelain gallbladder is a condition characterized by calcium salt deposits in the wall of a chronically inflamed gallbladder. The calcifications can be thin or faintly visible, or may be amorphous, patchy, and thick. The gallbladder is generally large, but its size can vary considerably. Most porcelain gallbladders are associated with gallstones. A plain radiograph generally detects these, but computed tomography (CT) has a higher specificity; therefore, a CT scan is performed to confirm the diagnosis. Due to their high risk of gallbladder carcinoma, all patients with porcelain gallbladder should have an elective cholecystectomy.
This syndrome was previously known as reflex sympathetic dystrophy, algodystrophy, causalgia, Sudeck atrophy, transient osteoporosis, and acute atrophy of bone. Usually occurring after an injury, CRPS presents with pain out of proportion to the injury, temperature change, edema, and abnormal skin color. Type I CRPS (90% of CRPS cases) occurs without a definable nerve lesion, while type II occurs with a definable nerve lesion. The pathogenesis is likely due to an injury causing increased sensitivity to sympathetic nerves, an abnormal response to and sensation of pain, and increased neuropeptide release causing burning pain to light touch (allodynia).
TransMedics’ proprietary Organ Care System (OCS) is the first commercial and portable warm blood perfusion organ transport system. With the OCS, doctors are able to perform “living organ transplants,” where organs are kept warm and functioning in a controlled environment from the time they are recovered to the moment they are placed in the recipient’s body.
Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks. There are four basic types of bipolar disorder; all of them involve clear changes in mood, energy, and activity levels.
Diagnosis of this condition is based on clinical symptoms alone, as there are no diagnostic laboratory tests. In order to meet the criteria for Tourette syndrome, both motor and vocal tics must be present before the age of 21 , and the tics must occur many times a day for at least 12 months which is the case in this patient. Tourette syndrome is associated with several comorbid conditions, with attention-deficit hyperactivity disorder (ADHD) and obsessive compulsive disorder (OCD) the most common. OCD is therefore the condition this child is most at risk of developing in the future.
This is a video which discusses the Vioptix tOX system of near infrared spectroscopy for the monitoring of free tissue transfer. Having information as to the health of the microvascular anastomosis is critical to improved patient outcome and free tissue survival. With better monitoring, supplementing clinical evaluation, surgeons are able to assess the health of the free tissue better and potentially improve patient outcome. The example in this video is of a free breast reconstruction where the tOX system was used to remotely monitor the free flap. The surgeon can follow the flap real time and more importantly follow trend lines to help predict flap complications.
The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS).
This cyst had been slowly growing for decades and created some redundant skin on the surface. A decision was made to make a slightly bigger incision in order to remove this tissue as well. As a result of this deeper process, 2 deep dermal sutures were added before the superficial interrupted sutures were put in place.

How does emergency contraception work to prevent pregnancy? What are the different types of emergency contraception? This video answers these questions and more.
