In emergencies (eg, asystole), transcutaneous pacing should be tried first. If transvenous pacing is tried, the catheter should be advanced during asynchronous pacing at maximum output until the ventricle has been captured and a palpable pulse is detected in the patient.

Pyogenic liver abscess Email this page to a friend Email this page to a friend Facebook Twitter Google+ Pyogenic liver abscess is a pus-filled area in the liver. Causes There are many potential causes of liver abscesses, including: Abdominal infection, such as appendicitis, diverticulitis, or a perforated bowel Infection in the blood Infection of the bile draining tubes Recent endoscopy of the bile draining tubes Trauma that damages the liver The most common bacteria that cause liver abscesses are: Escherichia coli Bacteroides Enterococcus Klebsiella pneumoniae Staphylococcus aureus Streptococcus In most cases, more than one type of bacteria is found.

Tuberculosis (TB) is a potentially serious infectious disease that mainly affects your lungs. The bacteria that cause tuberculosis are spread from one person to another through tiny droplets released into the air via coughs and sneezes.

"How to Perform a Transthoracic Echocardiographic Study Volume 1: Transducer Position and Anatomy" is an instructional video, offered by ASE, and can be used for professional lectures and offers an interactive section for flexible presentations. The video includes an overview of relevant cardiac anatomy, a step by step presentation of all Transducer Positions, and the sequential transducer movements to acquire standard echo images needed to complete a Transthoracic Echocardiographic Study.

Common causes of the knee pain
Knee pain is very common and in this video we will present the most common problems that can cause pain in the knee. (Patella) itself, which is in front of the knee, or from the tendons that are attached to the kneecap (patellar tendon and quadricep tendon). One of the most common problems is patellar chondromalacia which is chronic pain due to the softening of the cartilage beneath the kneecap. The cartilage of the kneecap will have some erosions, defects, or holes from mild to complete inside the joint (exactly in the back of the kneecap).
• Pain in the front of the knee
• Occurs more in young people
• Becomes worse from climbing up stairs and going downstairs
Treatment is usually nonsteroidal anti-inflammatory medication, physical therapy, and surgery is very rare. Also in front of the kneecap, the patient may get pain due to prepatellar bursitis.
When there is prepatellar bursitis, the patient will see that the swelling, the inflammation, and the pain is located over the front of the kneecap. The bursa becomes inflamed and fills with fluid at the top of the knee, causing pain, swelling, tenderness and a lump in that area on top of the kneecap. If the pain is in front of the knee but below or above the patella, this may indicate that the patient has tendonitis. Patellar tendonitis is an overuse condition that often occurs in athletes who perform repetitive jumping activities. Patellar tendonitis is a knee pain that is associated with focal patellar tendon tenderness and it is usually activity related. It is located below the kneecap and is called "jumper's knee". Patellar tendonitis affects approximately 20% of jumping athletes. There will be tenderness to palpation at the distal pole of the patella in extension and not in flexion. Quadriceps inflexibility, atrophy and hamstring tightness are predisposing factors for this condition. Treatment is rest, anti-inflammatory medication, stretching and strengthening of the hamstrings and quadriceps. Use an eccentric exercise program. The early stages of patellar tendonitis will respond well to nonoperative treatment. Another important cause of knee pain is a meniscal tear. The meniscus is the cushion that protects the cartilage in the knee. Injury will cause pain on the medial or the lateral side of the knee exactly at the level of the joint. The patient will complain of a history of locking, instability and swelling of the knee. McMurray test will be positive. A painful pop or click is obtained as the knee is brought from flexion to extension with either internal or external rotation of the knee. Arthritis of the knee Knee arthritis is very common. The cartilage cells die with age and its repair response decreases in the joint collapses with increased breakdown of the framework of the cartilage. The patient will have progressive blurring away of the cartilage of the joint with decreased joint space as seen on x-rays. Another source of pain is the Baker's cyst. The cyst is in the back of the knee between the semimembranosus yes and the medial gastrocnemius muscles. Another important source of knee pain is a ligament injury. Here is a normal knee without a ligament injury. Here you can see from the front, you can see the lateral and medial collateral ligament. You can see the ACL and PCL from the side view. These ligaments are usually injured as a result of a sports activity. Here is an example of a sports knee injury. Here is an example of the medial collateral ligament injury. This is the most commonly injury knee ligament injury to this ligament is on the inner part of the knee. Here is an example of an injury of the anterior cruciate ligament. It involves a valgus stress to the knee. Lachman test is usually positive, and MRI is diagnostic. Another important cause of knee pain is iliotibial band syndrome of the knee. Inflammation of the thickening of the iliotibial band results from excessive friction as the iliotibial band slides over the lateral femoral condyle. The iliotibial band is a thick band of fascia that extends along the lateral thigh from the iliac crest to the knee. And as the knee moves, the IT band was repeatedly shifted forwards and backwards across the lateral femoral condyle. The patient will complain of swelling, tenderness, and crepitus over the lateral femoral condyle. The condition occurs in the ITB S occurs in runners, cyclist and athletes that require repeated knee flexion and extension. The pain may be reproduced by doing a single-leg squat. The Ober's test is used to at assess tightness of the iliotibial band. MRI may show edema in the area of the ITB. Treatment is usually nonoperative with rest and ice, physical therapy, with stretching, proprioception, and improvement in neuromuscular coordination. Training modification and injections may be helpful. Surgery is a last resort. Surgical excision of the scarred inflamed part of the iliotibial band.

mply put, relapses, also known as flare ups, or (MS) attacks are new or worsening MS symptoms. But there is a concrete definition used by healthcare providers to identify MS attacks. To be considered an MS relapse: Old symptoms of MS must have become worse or new symptoms appeared.
