The pituitary is a small gland found inside the skull just below the brain and above the nasal passages, which are above the fleshy back part of the roof of the mouth (known as the soft palate). The pituitary sits in a tiny bony space called the sella turcica. The nerves that connect the eyes to the brain, called the optic nerves, pass close by it.
A surgeon creates an arteriovenous fistula by making a connection between an artery (which carries blood away from the heart) and a vein (which carries blood back to the heart). This artificial connection allows the vein to become larger and for the walls of the vein to thicken, a process termed maturation. A mature fistula makes it easier for the vein to be punctured repeatedly for dialysis. Maturation typically takes three to six months to occur, but in rare cases, can take up to a year. This makes advance planning for an arteriovenous fistula important. When a patient is felt to be approximately a year away from requiring dialysis, the patient should be referred for evaluation for possible creation of an arteriovenous fistula.
An appendectomy (sometimes called appendisectomy or appendicectomy (British English)) is the surgical removal of the vermiform appendix. This procedure is normally performed as an emergency procedure, when the patient is suffering from acute appendicitis. In the absence of surgical facilities, intravenous antibiotics are used to delay or prevent the onset of sepsis; it is now recognized that many cases will resolve when treated perioperatively. In some cases the appendicitis resolves completely; more often, an inflammatory mass forms around the appendix, causing transruptural flotation. This is a relative contraindication to surgery.
These air sacs make up most of the lung tissue. Lung diseases affecting the alveoli include: Pneumonia: An infection of the alveoli, usually by bacteria. Tuberculosis: A slowly progressive pneumonia caused by the bacteria Mycobacterium tuberculosis. Chronic respiratory diseases are chronic diseases of the airways and other structures of the lung. Some of the most common are: asthma, chronic obstructive pulmonary disease, occupational lung diseases and pulmonary hypertension.
The foods for your child are easily digestible foods, such as rice cereal, pasta, breads, cooked beans, mashed potatoes, cooked carrots, applesauce, and bananas. Pretzels or salty crackers can help your child replace the salt lost from diarrhea. Foods containing large amounts of sugar or fat should be avoided.
Bovine respiratory disease (BRD) has a multifactorial etiology and develops as a result of complex interactions between environmental factors, host factors, and pathogens. Environmental factors (eg, weaning, transport, commingling, crowding, inclement weather, dust, and inadequate ventilation) serve as stressors that adversely affect the immune and nonimmune defense mechanisms of the host. In addition, certain environmental factors (eg, crowding and inadequate ventilation) can enhance the transmission of infectious agents among animals. Many infectious agents have been associated with BRD. An initial pathogen (eg, a virus) may alter the animal’s defense mechanisms, allowing colonization of the lower respiratory tract by bacteria.
CRT is a clinically proven treatment option for some individuals with heart failure. A CRT device sends small electrical impulses to both lower chambers of the heart to help them beat together in a more synchronized pattern. This may improve the heart’s ability to pump blood and oxygen to your body. A CRT system is made up of two parts. The heart device, which is actually a tiny computer, plus a battery, contained in a small titanium metal case that is about the size of a pocket watch. Insulated wires, called leads, that are implanted to carry information signals from your heart to the heart device and to carry electrical impulses to your heart After the device system is implanted, an external computer, called a programmer, located at your doctor's office or clinic can be used to program the heart device and retrieve information from your heart device that will assist your doctor in your heart failure treatment. Your doctor will schedule periodic monitoring which may be done remotely if physician deems appropriate
Learn about electromagnetic navigation diagnostic bronchoscopy, a new technology used to diagnose small lung cancer tumors as small as a pencil eraser before they have the chance to spread. Cleveland Clinic physician Dr. Thomas Gildea demonstrates how this endobronchial ultrasound procedure, which involves using a small camera probe inserted thru the nose into the lungs, allows doctors to reach possible cancer in the lungs that they could never reliably get to before
Like any syndrome, fetal alcohol syndrome (FAS) is a group of signs and symptoms that appear together and indicate a certain condition. In the case of FAS, the signs and symptoms are birth defects that result from a woman's use of alcohol during her pregnancy.
