Upper right quadrant: The right upper quadrant contains the liver and gallbladder, which are protected by the lower right part of the ribcage. The large intestine, or colon, also spends a little time in this section. Upper left quadrant: The left upper quadrant contains part of the stomach and the spleen.
Thoracentesis is a procedure in which a needle is inserted into the pleural space between the lungs and the chest wall. This procedure is done to remove excess fluid, known as a pleural effusion, from the pleural space to help you breathe easier. It may be done to determine the cause of your pleural effusion. Some conditions such as heart failure, lung infections, and tumors can cause pleural effusions.
Simple microinstruments and a medical school laboratory microscope were used for anastomosis training. Chicken blood vessels were used as a material for this study. A long segment of blood vessel from the proximal brachial artery to the distal radial artery was used for training. End-to-side anastomosis was practiced first, and the training continued with end-to-end anastomosis of the appropriate segments.
What is the spleen and what causes an enlarged spleen (splenomegaly)? The spleen sits under your rib cage in the upper left part of your abdomen toward your back. It is an organ that is part of the lymph system and works as a drainage network that defends your body against infection. White blood cells produced in the spleen engulf bacteria, dead tissue, and foreign matter, removing them from the blood as blood passes through it. The spleen also maintains healthy red and white blood cells and platelets; platelets help your blood clot. The spleen filters blood, removing abnormal blood cells from the bloodstream. A spleen is normally about the size of your fist. A doctor usually can't feel it during an exam. But diseases can cause it to swell and become many times its normal size. Because the spleen is involved in many functions, many conditions may affect it.
Vaginal discharge serves an important housekeeping function in the female reproductive system. Fluid made by glands inside the vagina and cervix carries away dead cells and bacteria. This keeps the vagina clean and helps prevent infection. Most of the time, vaginal discharge is perfectly normal. The amount can vary, as can odor and hue (its color can range from clear to a milky white-ish), depending on the time in your menstrual cycle. For example, there will be more discharge if you are ovulating, breastfeeding, or are sexually aroused. The smell may be different if you are pregnant or you haven't been diligent about your personal hygiene. None of those changes is cause for alarm. However, if the color, smell, or consistency seems significantly unusual, especially if it accompanied by vaginal itching or burning, you could be noticing an infection or other condition. What causes abnormal discharge? Any change in the vagina's balance of normal bacteria can affect the smell, color, or discharge texture. These are a few of the things that can upset that balance:
A VCUG (Voiding Cystourethrogram) is a test that looks at how well your child's kidneys, ureters and bladder are working. Your child's kidneys make urine. The urine flows from the kidneys through thin tubes (called ureters) into your child's bladder.
People whose back or neck pain has not been relieved by back surgery or other treatments may have another option to consider: spinal cord stimulation. Around the world, some 14,000 patients undergo spinal cord stimulator implants each year. Spinal cord stimulation (SCS) delivers mild electrical stimulation to nerves along the spinal column, modifying or blocking nerve activity in a non-medicinal way to minimize the sensation of pain reaching the brain.
Frostbite is an injury caused by freezing of the skin and underlying tissues. First your skin becomes very cold and red, then numb, hard and pale. Frostbite is most common on the fingers, toes, nose, ears, cheeks and chin. Exposed skin in cold, windy weather is most vulnerable to frostbite. But frostbite can occur on skin covered by gloves or other clothing.
Visualization of the larynx by direct or indirect means is referred to as laryngoscopy and is the principal aim during airway management for passage of a tracheal tube. This paper presents a brief background regarding the development and practice of laryngoscopy and examines the equipment and techniques for both direct and indirect methods. Patient evaluation during the airway examination is discussed, as are predictors for difficult intubation. Laryngoscope blade design, newer intubating techniques, and a variety of indirect laryngoscopic technologies are reviewed, as is the learning curve for these techniques and devices.
Cystic fibrosis is a disease passed down through families that causes thick, sticky mucus to build up in the lungs, digestive tract, and other areas of the body. It is one of the most common chronic lung diseases in children and young adults. It is a life-threatening disorder.
Morning erections have colloquially been termed as “morning wood” while scientifically it is called nocturnal penile tumescence. It is a normal and healthy physiological reaction and response that most men experience in their lives. Morning erections are really the ending of a series of erections that happen to men during the night. Healthy men can, on average, have anywhere between three to five erections in a full night of sleep, each of which lasts from 25-35 minutes.
Patellar tendon rupture is a rupture of the tendon that connects the patella to the tibia. The superior portion of the patellar tendon attaches on the posterior portion of the patella, and the posterior portion of the patella tendon attaches to the tibial tubercle on the front of the tibia.
