Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function. You're most likely to contract hepatitis A from contaminated food or water or from close contact with someone who's infected. Mild cases of hepatitis A don't require treatment, and most people who are infected recover completely with no permanent liver damage. Practicing good hygiene, including washing hands frequently, is one of the best ways to protect against hepatitis A. Vaccines are available for people most at risk.
This surgical animation is for patient education and describes a laparoscopic colectomy, which is a type of minimally invasive surgery for colon cancer. Laparoscopic colectomy, also called minimally invasive colectomy, involves several small incisions in your abdomen. Instead of a big incision, the surgeon makes a few small cuts (0.5-1 centimeters) in the abdominal cavity to insert a surgical camera and instruments and perform the operation. A slightly bigger incision, about 3.5 centimeters wide, is made to remove the tumor.
When compared to traditional open surgery, laparoscopic colectomy can result in much less pain and swifter recovery. Depending on the procedure, most laparoscopic colectomy patients leave the hospital and return to normal activities more quickly than patients recovering from open surgery.
Colorectal cancer is the second leading cause of cancer death in the United States.

Laparoscopy (from Ancient Greek λαπάρα (lapára) 'flank, side', and σκοπέω (skopéō) 'to see') is an operation performed in the abdomen or pelvis using small incisions (usually 0.5–1.5 cm) with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.[1]
Laparoscopic surgery, also called minimally invasive procedure, bandaid surgery, or keyhole surgery, is a modern surgical technique. There are a number of advantages to the patient with laparoscopic surgery versus an exploratory laparotomy. These include reduced pain due to smaller incisions, reduced hemorrhaging, and shorter recovery time. The key element is the use of a laparoscope, a long fiber optic cable system that allows viewing of the affected area by snaking the cable from a more distant, but more easily accessible location.
Laparoscopic surgery includes operations within the abdominal or pelvic cavities, whereas keyhole surgery performed on the thoracic or chest cavity is called thoracoscopic surgery. Specific surgical instruments used in laparoscopic surgery include obstetrical forceps, scissors, probes, dissectors, hooks, and retractors. Laparoscopic and thoracoscopic surgery belong to the broader field of endoscopy. The first laparoscopic procedure was performed by German surgeon Georg Kelling in 1901. There are two types of laparoscope:[2]
A telescopic rod lens system, usually connected to a video camera (single-chip or three-chip)
A digital laparoscope where a miniature digital video camera is placed at the end of the laparoscope, eliminating the rod lens system
The mechanism mentioned in the second type is mainly used to improve the image quality of flexible endoscopes, replacing conventional fiberscopes. Nevertheless, laparoscopes are rigid endoscopes. Rigidity is required in clinical practice. The rod-lens-based laparoscopes dominate overwhelmingly in practice, due to their fine optical resolution (50 µm typically, dependent on the aperture size used in the objective lens), and the image quality can be better than that of the digital camera if necessary. The second type of laparoscope is very rare in the laparoscope market and in hospitals.[citation needed]
Also attached is a fiber optic cable system connected to a "cold" light source (halogen or xenon) to illuminate the operative field, which is inserted through a 5 mm or 10 mm cannula or trocar. The abdomen is usually insufflated with carbon dioxide gas. This elevates the abdominal wall above the internal organs to create a working and viewing space. CO2 is used because it is common to the human body and can be absorbed by tissue and removed by the respiratory system. It is also non-flammable, which is important because electrosurgical devices are commonly used in laparoscopic procedures.[3]
Procedures
Surgeons perform laparoscopic stomach surgery.
Patient position
During the laparoscopic procedure, the position of the patient is either in Trendelenburg position or in reverse Trendelenburg. These positions have an effect on cardiopulmonary function. In Trendelenburg's position, there is an increased preload due to an increase in the venous return from lower extremities. This position results in cephalic shifting of the viscera, which accentuates the pressure on the diaphragm. In the case of reverse Trendelenburg position, pulmonary function tends to improve as there is a caudal shifting of viscera, which improves tidal volume by a decrease in the pressure on the diaphragm. This position also decreases the preload on the heart and causes a decrease in the venous return leading to hypotension. The pooling of blood in the lower extremities increases the stasis and predisposes the patient to develop deep vein thrombosis (DVT).[4]
Gallbladder
Rather than a minimum 20 cm incision as in traditional (open) cholecystectomy, four incisions of 0.5–1.0 cm, or more recently, a single incision of 1.5–2.0 cm,[5] will be sufficient to perform a laparoscopic removal of a gallbladder. Since the gallbladder is similar to a small balloon that stores and releases bile, it can usually be removed from the abdomen by suctioning out the bile and then removing the deflated gallbladder through the 1 cm incision at the patient's navel. The length of postoperative stay in the hospital is minimal, and same-day discharges are possible in cases of early morning procedures.[citation needed]
Colon and kidney
The gold standard treatment for bladder outlet obstruction.This is an endoscopic procedure in which a resectoscope is placed transurethrally and the obstructing lobes of the prostate are removed as chips of tissue. TURP results in improvement of flow rate, and symptom scores are superior to that of other minimally invasive therapies
The baby suffered from ectopia cordis, a rare condition where a baby's heart is located either partially or totally outside the chest. Only 8 out of 1 million babies are born with the condition, and 90 percent of those babies are either stillborn or die within the first three days of life.
Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle.
Elbow Exam - Orthopaedic OSCE - Clinical Skills - Dr Gill
The elbow examination is a core skill - in this video, we demonstrate how to perform an elbow EXAM for an Orthopaedic Clinical Skills OSCE, which should be one of the more accessible examination stations for medical students.
For a passing grade in your Clinical Skills OSCE, an elbow assessment should follow the LOOK, FEEL, MOVE approach
Initially looking for erythema, scars, swelling and position
Palpating the elbow - specifically the olecranon, medial and lateral epicondyles, and radial head for heat, oedema and crepitus
Finally assess range of movement with flexion and extension at the elbow, before determining for tennis and golfers' elbows

------------
Please note that there is no ABSOLUTE way to perform a clinical examination. Different institutions and even clinicians will have differing degrees of variations - the aim is the effectively identify medically relevant signs.
However during OSCE assessments. Different medical schools, nursing colleges and other health professional courses will have their own preferred approach to a clinical assessment - you should concentrate on THEIR marks schemes for your assessments.
The examination demonstrated here is derived from Macleods Clinical Examination - a recognised standard textbook for clinical skills.

The major elements of the cardiac exam include observation, palpation and, most importantly, auscultation (percussion is omitted). As with all other areas of the physical exam, establishing adequate exposure and a quiet environment are critical. Initially, the patient should rest supine with the upper body elevated 30 to 45 degrees. Most exam tables have an adjustable top. If not, use 2 or 3 pillows. Remember that although assessment of pulse and blood pressure are discussed in the vital signs section they are actually important elements of the cardiac exam.
