Laryngectomy is the removal of the larynx and separation of the airway from the mouth, nose and esophagus. In a total laryngectomy the entire larynx is removed and in a partial laryngectomy only a portion is taken out. The laryngectomee breathes through an opening in the neck known as a stoma.
6 987 24 MORE How Does Anesthesia Work? Credit: itsmejust | Shutterstock If you’ve ever had surgery, unless you are super tough, you’ve gone through it with the benefit of anesthetics. But, how do these body-numbing elixirs work? Prior to the invention of anesthesia in the mid-1800s, surgeons had to hack off limbs, sew up wounds and remove mysterious growths with nothing to dull the patient's pain but opium or booze. While these drugs may have numbed the patient, they didn’t always completely block the pain, or erase the memory of it. Since then, doctors have gotten much better at putting us out with drug combinations that ease pain, relax muscles and, in some cases, put us in a deep state of hypnosis that gives us temporary amnesia. Today, there are two primary types of anesthesia drugs: those that knockout the whole body (general) and those that only numb things up locally.
Nasal polyps are soft, painless, noncancerous growths on the lining of your nasal passages or sinuses. They hang down like teardrops or grapes. They result from chronic inflammation due to asthma, recurring infection, allergies, drug sensitivity or certain immune disorders.
The external jugular vein receives the greater part of the blood from the exterior of the cranium and the deep parts of the face, being formed by the junction of the posterior division of the retromandibular vein with the posterior auricular vein.
Technically, there's no formal definition for a "Code", but doctors often use the term as slang for a cardiopulmonary arrest happening to a patient in a hospital or clinic, requiring a team of providers (sometimes called a "code team") to rush to the specific location and begin immediate resuscitative efforts.
Waardenburg syndrome is a group of genetic conditions that can cause hearing loss and changes in coloring (pigmentation) of the hair, skin, and eyes. Although most people with Waardenburg syndrome have normal hearing, moderate to profound hearing loss can occur in one or both ears. The hearing loss is present from birth (congenital). People with this condition often have very pale blue eyes or different colored eyes, such as one blue eye and one brown eye. Sometimes one eye has segments of two different colors. Distinctive hair coloring (such as a patch of white hair or hair that prematurely turns gray) is another common sign of the condition. The features of Waardenburg syndrome vary among affected individuals, even among people in the same family.
Diarrhea in Children: Common Causes and Treatments Diarrhea is the body's way of ridding itself of germs, and most episodes last a few days to a week. Diarrhea often occurs with fever, nausea, vomiting, cramps, and dehydration. Some of the most common reasons kids get diarrhea include: Infection from viruses like rotavirus, bacteria like salmonella and, rarely, parasites like giardia. Viruses are the most common cause of a child's diarrhea. Along with loose or watery stools, symptoms of a viral gastroenteritis infection often include vomiting, stomachache, headache, and fever. When treating viral gastroenteritis -- which can last 5-14 days -- it's important to prevent fluid loss. Offer additional breast milk or an oral rehydration solution (ORS) to infants and young children. Water alone doesn't have enough sodium, potassium, and other nutrients to safely rehydrate very young children. Be sure to talk to your doctor about the amount of fluids your child needs, how to make sure he or she gets them, when to give them, and how to watch for dehydration. Older children with diarrhea can drink anything they like to stay hydrated, including ORS and brand-name products (their names usually end in "lyte"). Popsicles can also be a good way to get fluids into a child who's been vomiting and needs to rehydrate slowly.
Cytoplasmic organelles are "little organs" that are suspended in the cytoplasm of the cell. Each type of organelle has a definite structure and a specific role in the function of the cell. Examples of cytoplasmic organelles are mitochondrion, ribosomes, endoplasmic reticulum, golgi apparatus, and lysosomes.
Signs and symptoms of this condition typically appear around the age of 3 or 4 months, when babies start to sleep through the night and do not eat as frequently as newborns. Affected infants may have low blood sugar (hypoglycemia), which can lead to seizures. They can also have a buildup of lactic acid in the body (lactic acidosis), high blood levels of a waste product called uric acid (hyperuricemia), and excess amounts of fats in the blood (hyperlipidemia). As they get older, children with GSDI have thin arms and legs and short stature. An enlarged liver may give the appearance of a protruding abdomen. The kidneys may also be enlarged. Affected individuals may also have diarrhea and deposits of cholesterol in the skin (xanthomas).
Cushing's disease is a serious condition of an excess of the steroid hormone cortisol in the blood level caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). ACTH is a hormone produced by the normal pituitary gland. ACTH stimulates the adrenal glands (located on top of the kidneys) to produce cortisol, commonly referred to as the stress hormone.
Nelson syndrome refers to a spectrum of symptoms and signs arising from an adrenocorticotropin (ACTH)–secreting pituitary macroadenoma after a therapeutic bilateral adrenalectomy. The spectrum of clinical features observed relates to the local effects of the tumor on surrounding structures, the secondary loss of other pituitary hormones, and the effects of the high serum concentrations of ACTH on the skin. [1] The first case was reported by Nelson et al in 1958. [2]
NTIS refers to a syndrome found in seriously ill or starving patients with low fT3, usually elevated RT3, normal or low TSH, and if prolonged, low fT4. It is found in a high proportion of patients in the ICU setting, and correlates with a poor prognosis if TT4 is <4ug/dl. The patho-physiology includes suppression of TRH release, reducedT3 and T4 turnover, reduction in liver generation of T3, increased formation of RT3, and tissue specific down-regulation of deiodinases, transporters, and TH receptors. Although long debated, tissue TH levels are definitely reduced, and tissue hypothyroidism is presumably present. This is often not clinically evident because of the brief duration, and reduced but not absent tissue levels of TH. Although recognized for nearly 4 decades, interpretation of the syndrome is contested, because of lack of data. Some observes, totally without data, argue that it is a protective response and should not be treated. Other observers (as in this review) present available data suggesting, but not proving, that thyroid hormone replacement is appropriate, not harmful, and may be beneficial. The best form of treatment (TRH,TSH,or T3+T4) and possible accompanying treatments (GHRH, Cortisol, nutrition, insulin) lack consensus. In this review current data are laid out for reader’s review and judgment.
The lungs and respiratory system allow oxygen in the air to be taken into the body, while also enabling the body to get rid of carbon dioxide in the air breathed out. Respiration is the term for the exchange of oxygen from the environment for carbon dioxide from the body's cells.
Gastroparesis -- literally “paralyzed stomach” -- is a serious condition manifested by delayed emptying of stomach contents into the small intestine after a meal. There is no cure for gastroparesis, but treatment can speed gastric emptying and relieve gastrointestinal symptoms such as nausea and vomiting.
