Animal Hospital

Image
Animal Hospital *** Relevant Background: " A  veterinarian  ( vet ), also known as a  veterinary surgeon  or  veterinary physician , is a professional who practices  veterinary medicine  by treating diseases, disorders, and injuries in non-human  animals .... Most veterinary physicians work in clinical settings, treating animals directly. These veterinarians may be involved in a general practice, treating animals of all types; they may be specialized in a specific group of animals such as  companion animals ,  livestock ,  zoo animals  or  equines ; or may specialize in a narrow medical discipline such as  surgery ,  dermatology  or  internal medicine  . As with other healthcare professionals, veterinarians face ethical decisions about the care of their patients. [1]  Current debates within the profession include the ethics of certain procedures believed to be purely cosmetic or unnecessary f...

Epilepsy Surgery

Image
  Epilepsy Surgery *** Relevant Background: " Epilepsy surgery  involves a  neurosurgical  procedure where an area of the  brain  involved in  seizures  is either resected, disconnected or stimulated.. The evaluation for epilepsy surgery is designed to locate the "epileptic focus" (the location of the epileptic abnormality) and to determine if resective surgery will affect normal brain function. The definition of the epileptogenic zone has a fundamental role in determining the boundaries of the area that needs to be removed in order to achieve seizure freedom but also in order not to harm “eloquent cortex” (damage to this area produces neurological deficit). As the localization technology has improved, the definition of the epileptogenic zone has expanded to comprise a larger area of the brain than before. [4]   Resective surgery involves the resection, or cutting away, of brain tissue from the area of the brain that consists of the epilepti...

Skin Surgery

Skin Surgery ********************************************************************** Relevant Background: " Plastic surgery  is a surgical specialty involving the restoration, reconstruction, or alteration of the human body. It can be divided into two main categories:  reconstructive surgery  and  cosmetic surgery .   Reconstructive surgery  includes  craniofacial surgery ,  hand surgery ,  microsurgery , and the treatment of  burns . While reconstructive surgery aims to reconstruct a part of the body or improve its functioning, cosmetic (or aesthetic) surgery aims at improving the appearance of it. [1] [2]  Both of these techniques are used throughout the world... Plastic surgery is a broad field, and may be subdivided further. In the United States, plastic surgeons are board certified by   American Board of Plastic Surgery . [18]   Subdisciplines of plastic surgery may include:... Aesthetic surgery is a central component...

Pacemaker Surgery

Image
  Pacemaker Surgery *********************************************************** Relevant Background: " A cardiac   pacemaker   (or   artificial pacemaker , so as not to be confused with the   natural pacemaker   of the   heart ), is a medical device that generates electrical impulses delivered by   electrodes   to cause the heart muscle chambers (the upper, or   atria   and/or the lower, or   ventricles ) to contract and therefore pump blood; by doing so this device replaces and/or regulates the function of the   electrical conduction system of the heart .... The primary purpose of a pacemaker is to maintain an adequate   heart rate , either because the heart's natural pacemaker is not fast enough, or because there is a   block   in the heart's electrical conduction system. Modern pacemakers are externally programmable and allow a cardiologist, particularly a   cardiac electrophysiologist   to sel...

Ear Surgery

Image
  Ear Surgery ************************************************* Relevant Background: " A   cochlear implant   ( CI ) is a surgically implanted neuroprosthetic device to provide a person with moderate to profound sensorineural hearing loss a modified sense of sound. CI bypasses the normal acoustic hearing process to replace it with electric signals which directly stimulate the auditory nerve. A person with a cochlear implant receiving intensive auditory training may learn to interpret those signals as sound and speech. However, one third of deaf children do not develop language if they are on a CI program alone and have no sign language input.  The implant has two main components. The outside component is generally worn behind the ear, but could also be attached to clothing, for example, in young children. This component, the sound processor, contains microphones, electronics that include   digital signal processor   (DSP) chips, battery, and a coil which t...

Leg Surgery

Leg Surgery ****************************************************************** Relevant Background on Leg Fracture: " A   fracture   of the leg can be classified according to the involved   bone   into: Femoral fracture (in the upper leg) Crus fracture (in the lower leg)..." (" Human Leg ",  https://en.wikipedia.org/wiki/Human_leg#Fracture ) Relevant Background on Femoral Fracture:  "A  femoral fracture  is a  bone fracture  that involves the  femur . They are typically sustained in high-impact trauma, such as car crashes, due to the large amount of force needed to break the bone. Fractures of the  diaphysis , or middle of the femur, are managed differently from those at the head, neck, and trochanter..." (" Femoral Fracture ",  https://en.wikipedia.org/wiki/Femoral_fracture ) *** Relevant Background on Crust Fracture: " A  crus fracture  is a  fracture  of the  lower legs   bones ...
