What Is Cancer Of The Pharynx?

[dropcap]C ancer of the pharynx is a malignant growth of stratified squamous cells that line the pharynx, or throat.

Q: What are stratified squamous cells that line the pharynx?

A: Stratified squamous cells are thin, flat epithelial cells consisting of several layers forming the surface mucosa that protects underlying layers of the pharynx. These cells lie very close together and have no blood vessels.

The pharynx is the upper passageway of the throat where swallowing food and fluids from the mouth first pass on the way to the esophagus and breathing air passes from the nose and mouth to and from the lungs.

The pharynx provides for speech production, adequate taste reception, and proper hearing through equalization of air pressure in the eustachian tubes.

The pharynx has three areas and pharyngeal cancer can occur in any of them: the nasopharynx behind the nose, the oropharynx behind the mouth, and the hypopharynx or laryngopharynx, just above the larynx. Tonsils, adenoids, and other lymph tissue lie at the back of the throat.

Unfortunately, cancers of the pharynx tend not to be detected until late in their course when symptoms become evident. This makes the prognosis poor. See symptom below.

What Is Primary Addison’s Disease?

[dropcap]A ddison’s disease is an autoimmune destruction of the adrenal glands by autoantibodies that target the adrenal cortex, or outer part of these glands, and is characterized by a slow progressive failure of the adrenal glands to adequately produce its steroid hormones.

Symptoms of adrenal fatigue or failure may not develop until the majority of adrenal tissue is destroyed. When untreated, progression leads to coma, called Addisonian crisis, which is a medical emergency.

There are two adrenal glands each located on top of a kidney and enclosed in a connective tissue capsule. Each is a small, triangular shape that is made of two parts: the outer region and the inner region.

The inner region, called the adrenal medulla, produces epinephrine and norepinephrine chemicals that are needed to deal with stress.

The outer region, called the adrenal cortex, produces adrenocortical (steroid) hormones and releases them into the bloodstream in response to pituitary stimulating hormone from the brain.

Q: What is the function of steroid hormones produced by the adrenal glands?

A: Functions of the three steroid hormones produced by the adrenal glands are:

  1. Glucocorticoids restrain inflammation and metabolism of carbohydrates, fats and proteins to maintain a normal glucose blood level. The major glucocorticoid is hydrocortisone.
  2. Mineralocorticoids regulate the retention and excretion of fluids and electrolytes by the kidneys. The most important mineralocorticoid is aldosterone.
  3. Androgen (testosterone) is a male sex hormone.

Secondary adrenal insufficiency may develop from other causes that are not immune related such as chronic infections, tumor, and medications.

Lactose IntoleranceWhat Is Lactose Intolerance?

[dropcap]L actose intolerance is a well known symptom of carbohydrate malabsorption characterized by inability to properly digest lactose, the sugar in milk, due to low lactase digesting activity in the small intestine.

Lactase is an enzyme produced by specialized cells in the tips of villi within the brush border of the small intestinal lining that digests lactose.

Lactose is a disaccharide, or double sugar, made up of a molecule of glucose and a molecule of galactose (simple sugars). Lactose cannot be absorbed as is into the body unless it is broken down by lactase into glucose and galactose.

Q: How does lactose cause diarrhea?

A: If lactose is not broken down, undigested lactose moves into the colon where it acts osmotically to draw water from the walls of the colon into the lumen, which causes diarrhea by the unnatural amount of water. How much water? Can be 2 liters! Meanwhile, the normal population of colonic bacteria ferment the undigested lactose, generating short-chain fatty acids and hydrogen gas, resulting in bloating pain and flatulence.

Testing for intolerance is based on the action of lactose to increase intestinal permeability.1 Positive response to a breath hydrogen test (BHT), involving 1 – 3 hours of time post ingestion of lactose test dose, signifies malabsorption in the small intestine and fermentation in the colon. If BHT is positive before 60 minutes, the result implies bacteria is abnormally present in the small intestine, causing fermentation there.

Endoscopy is used to measure activity of lactase in a tissue sample.

Treatment is avoidance of milk and dairy products that contain lactose. Nevertheless, milk treated with lactase enzyme can be safely consumed. Fermented milk products like yogurt or kefir are safe because the lactose has been digested by organisms. If there is also a problem with milk protein, then no milk is acceptable that comes from the cow or animal that is causing the allergy.

What Is Acquired Cutis Laxa?

[dropcap]A cquired cutis laxa is an uncommon skin disorder characterized by abnormal reduction and degeneration of elastic fibers of the skin that can appear simply as thick, saggy skin with loose folds to severe involvement showing a premature aged appearance.

Q: What are elastic fibers of the skin?

A: Elastic fibers of the skin are connective tissue found in the dermis, which is the layer of skin under the epidermis, or surface layer. They hold the shape of skin and are important for wound healing in the development of scars.

What Is Seborrhea Dermatitis?

[dropcap]S eborrhea dermatitis is a recurring inflammatory disorder of sebaceous glands characterized by scaly patches of skin, often with bumps.

Seborrhea dermatitis results from the body’s inflammatory reaction to invasion by pityrosporum yeast that naturally inhabits the scalp and skin.1 Inflammation is the normal response to tissue injury and germ invasion.

Pityrosporum is a yeast that is commonly present worldwide. Its development depends on various factors that predispose to pityriasis versicolor, a chronic and mild superficial yeast infection. These infections usually are asymptomatic without itching or pain and without cellular and/or antibody responses.2

Q: Why are the sebaceous glands particularly affected by this yeast?

A: Pityrosporum yeast is an organism that needs oil produced by sebaceous glands to grow. If conditions permit, this yeast invades the superficial layer of skin and hair shafts to reproduce, causing infection. Such conditions include weakened skin due to nutritional deficiencies, excessive build-up of oil on skin, and altered immunity due to systemic disease such as psoriasis.

In adults, areas of skin that are the most affected have the greatest number of sebaceous glands especially the scalp, back, underarms, and the face including the eyelids, eyebrows and side folds of the nose.

All ages are subject to seborrhea dermatitis, and males have a higher occurence than females.

What Is Immune Thrombocytopenic Purpura?

[dropcap]I mmune thrombocytopenia purpura (ITP), formerly called idiopathic, is an immune mediated bleeding disorder characterized by destruction of circulating platelets (thrombocytes) by autoantibodies in the presence of normal bone marrow and without other conditions that cause bleeding problems including many medications.

Q: How do autoantibodies destroy platelets?

A: Autoantibodies bind to normal platelet surface antigens (targets) which forms a complex that is cleared from blood by the reticuloendothelial system. Consequently, this condition results in an abnormal decrease in the number of platelets circulating in blood plasma.

Platelets are cells that are needed to stop bleeding. A normal platelet count is in the range of 150,000 to 450,000. With ITP, the platelet count is less than 100,000. By the time significant bleeding occurs, the patient may have a platelet count of less than 10,000. The lower the platelet count, the greater the risk of bleeding. 

Because of inability of blood to properly clot due to lack of sufficient platelets, a distinctive purplish rash develops under the skin from blood leakage and an appearance of many small red spots of varying size can cover the skin. Depending on the number of platelets, there may be minimal to extensive bleeding in various parts of the body.  Bleeding in the brain is the worst complication, causing death in approximately 1% of affected children and 5% of affected adults.

Immune thrombocytopenic purpura is common in childhood, on average 50 cases per 1,000,000 per year with same incidence in boys as girls. It may follow a viral infection or immunization and is caused by an inappropriate response of the immune system to cross react against the body’s platelets.1

The incidence of immune thrombocytopenic purpura in adults is approximately 66 cases per 1,000,000 per year.  Older persons and persons with a previous history of hemorrhage are at increased risk of severe bleeding in adult ITP.  

Spontaneous remission occurs in most children (80%).  Remission in adults usually requires treatment.

QueijoFresco.

What Is Arachidonic Acid?

[dropcap]A[/dropcap]rachidonic acid is a major essential (must have/can’t make) omega-6 fatty acid.

Structurally, arachidonic acid is a key component of nerve membranes, together with docosahexaenoic acid (DHA), a major opposing omega-3 fatty acid, making up 15-20% of the brain’s dry mass and more than 30% of the retina.

In healthy human volunteers, positron emission tomography (PET) has shown that the normal human brain consumes 17.8 mg/day of arachidonic acid.1

Arachidonic acid is particularly concentrated in highly active membranes such as nerve synapses (junctions) and in photoreceptors in the eye retina.2

Arachidonic acid is an important building substance for the eicosanoids.

Q: What function do the eicosanoids have that are derived from arachidonic acid?

A: Eicosanoids are a large group of highly bioactive hormone-like substances including prostaglandins, leukotrienes, and thromboxanes that are involved in blood clotting, inflammation, and vasoconstriction. Eicosanoids derived from arachidonic acid are pro-inflammatory, pro-blood clotting, and constrict blood vessels in opposition to those derived from the omega-3 fatty acids which do the opposite in order to keep a balance in the body.

What Is A Pale, Smooth, Burning Tongue?

[dropcap]A pale, smooth, burning tongue is an alteration in tongue tissue characteristic of iron deficiency. The tongue is also swollen.1

Additionally, the sore tongue surface may be invaded by candida yeast which takes advantage of the sore tissue.

Iron deficiency itself increases susceptibility to infection.

Q: What is iron deficiency?

A: Iron deficiency results when the level within cells is too low to meet metabolic needs of the body for this mineral.

Deficiency is characterized by impaired red blood cell formation, free-radical disposal, oxygenation of cells, immune response to infection, enzyme activity, cognitive performance, digestion, nail structure, and fetal health.2

Iron is an essential mineral that is required for normal body function. Almost two-thirds of iron in the body is found in hemoglobin, the protein in red blood cells that carries oxygen to tissues. Smaller amounts of iron are found in myoglobin, a protein that helps supply oxygen to muscle, and in enzymes that assist biochemical reactions.

Iron is also found in proteins that store iron for future needs and that transport iron in blood. Iron stores are regulated by intestinal iron absorption.3
