This Video COPD, or chronic obstructive pulmonary (PULL-mun-ary) disease, is a progressive disease that makes it hard to breathe. "Progressive" means the disease gets worse over time. COPD can cause coughing that produces large amounts of mucus (a slimy substance), wheezing, shortness of breath, chest tightness, and other symptoms. Cigarette smoking is the leading cause of COPD. Most people who have COPD smoke or used to smoke. Long-term exposure to other lung irritants—such as air pollution, chemical fumes, or dust—also may contribute to COPD.
Vasectomy is a minor surgical procedure wherein the vasa deferentia of a man are severed, and then tied or sealed in a manner such to prevent sperm from entering the seminal stream (ejaculate). Typically done in an outpatient setting, a traditional vasectomy involves numbing (local anesthetic) of the scrotum after which 1 (or 2) small incisions are made, allowing a surgeon to gain access to the vas deferens.
Purpose: To evaluate the results of LASIK and IntraLASIK treatment in myopic patients with nystagmus. Methods: Eight patients with congenital nystagmus (16 eyes), from 23 to 49 years of age, underwent LASIK surgery. Corneal flaps were created using either the Hansatome microkeratome or the Intral...ase femtosecond laser. The ablations were performed with the Bausch & Lomb excimer laser with an active tracking system. In some patients, the eyes were fixated with forceps or a fixation ring during the laser ablation. Results: The refractive errors were corrected in all cases. There was no decentration or loss of best corrected visual acuity greater than 1 line. In 56% of the eyes, the post-operative uncorrected visual acuity was better than the best spectacle corrected-visual acuity (BSCVA). 62.5% of the eyes improved their BSCVA. The overall visual performance was improved in all the patients. One patient that did not not drive before become eligible to get a driver license after the surgery. Conclusions: Selected patients with myopia and congenital nystagmus may benefit from laser refractive surgery. Laser refractive surgery may be safely and accurately performed by using either the Hansatome microkeratome or the Intralase femtosecond laser and an active tracking system with or without mechanical fixation. Certain patients improve their BSCVA post-operatively.
http://www.highimpact.com - This brain surgery animation was used to demonstrate a young girl's craniotomy, cranioplasty, and reconstructive skull surgery after her vehicle was struck by a tractor-trailer. The procedures included the evacuation of a large epidural hematoma, the draining of the epidural space, and the reassembly of bone fragments to repair the skull.

WHAT HAPPENED
A teenage girl was riding home with her parents and boyfriend from a Wednesday night church service when a tractor-trailer struck the back driver’s side of their car as they were traveling through an intersection. The impact sent the car spinning into oncoming traffic where it struck another vehicle. When paramedics arrived, the 17-year-old was unresponsive with bleeding from her left ear and a laceration from behind her left ear.
She was rushed to the hospital where she underwent a series of CT scans that showed a severely comminuted open skull fracture with an underlying 1.1 cm subdural hematoma. She was taken to the operating room where an emergency craniotomy was performed to evacuate the hematoma and reassemble the skull fragments. The patient gradually began to wake up and was discharged six days later, after she showed she could maneuver up and down the hallway.
The biggest challenge in a traumatic brain injury case like this - where most of the damages are deeply underlying and undetectable on the surface - is that the only visual evidence is in the form of 2D black-and-white radiographic films. This can look ambiguous to the typical juror because it’s often difficult to discern where these snapshots are located inside the person’s skull. Tony Seaton, Esq., and Robert Bates, Esq., needed to reinforce this 2D radiographic evidence with maximum 3D context.
We equipped them with a custom Diagnostic Slice Chooser: an interactive presentation that presents radiographic slides within a three-dimensional model of the patient’s head. We also designed the model accurately to the patient’s likeness and colorized the films to highlight key areas of damage. The attorneys could show the complete depth and magnitude of his client’s injuries at every level both before and after the surgery. After establishing the full extent of damages, we also created an animation to walk viewers through the surgical experience the patient would undergo as a result of her injuries.
The visual presentation helped jurors understand the destructive impact this collision had on this young teenager’s life, and Mr. Seaton and Mr. Bates, Esq., were able to acquire a $4.5M settlement for his client.

rostbite refers to the freezing of body tissue (usually skin) that results when the blood vessels contract, reducing blood flow and oxygen to the affected body parts. Normal sensation is lost, and color changes also occur in these tissues.

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 medical animation shows laparoscopically assisted gallbladder removal surgery, or cholecystectomy. The animation begins by showing the normal anatomy of the liver and gallbladder. Over time, gallstones form within the gallbladder, blocking the cystic duct, and causing the gallbladder to become enlarged and inflamed. The procedure, sometimes called a "lap-chole", begins with the insertion of four trocar devices, which allow the physician to see inside the abdomen without making a large incision. Air is added to the abdominal cavity to make it easier to see the gall bladder. Next, we see a view through the laparascope, showing two surgical instruments grasping the gallbladder while a third severs the cystic duct. After the gallbladder is removed, the camera pans around to show that the cystic artery and vein, have already been clipped to prevent bleeding.

Transurethral resection of the prostate (also known as TURP, plural TURPs and as a transurethral prostatic resection TUPR) is a urological operation. It is used to treat benign prostatic hyperplasia (BPH). As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by electrocautery or sharp dissection. This is considered the most effective treatment for BPH. This procedure is done with spinal or general anesthetic. A large triple lumen catheter is inserted through the urethra to irrigate and drain the bladder after the surgical procedure is complete. Outcome is considered excellent for 80-90% of BPH patients. Because of bleeding risks associated with the surgery, TURP is not considered safe for many patients with cardiac problems. As with all invasive procedures, the patient should first discuss medications they are taking with their doctor, most especially blood thinners or anticoagulants, such as warfarin (Coumadin), or aspirin. These may need to be discontinued prior to surgery. Postop complications include bleeding (most common), clotting and hyponatremia (due to bladder irrigation).
Additionally, transurethral resection of the prostate is associated with low but important morbidity and mortality.
