Aortic Stenosis

Narrowing of the AORTIC VALVE in the HEART which obstructs the ?ow of blood through it, with serious effects on the heart and the circulation. The muscle in the left ventricle works harder to compensate for the obstruction and thickens as a result. Stenosis is usually caused by the deposition of calcium on the valve and is commonly associated with ATHEROMA. Untreated, the condition leads to heart failure, but nowadays the stenosis can be treated surgically.... aortic stenosis

Hormone Replacement Therapy (hrt)

Within a few years medical scientists have introduced into the domestic scene a steroid which has changed the whole course of female history. HRT has solved some basic medical problems by making good the loss of oestrogen in a woman’s body when menstruation is finished and her body learns to adjust.

A lack of oestrogen induces hot flushes, night sweats, thinning of the bones (osteoporosis) with possible fractures, and a wide range of physical and emotional disorders.

HRT also prevents the increased frequency of coronary disease which may follow the menopause. With oestrogen only, HRT appears to increase the incidence of cancer of the uterine body. Use of oestrogen and progestogen avoids this.

HRT is available as a tablet, transdermal patch, implant or topical cream. Most women notice temporary improvement in their appearance and hot flushes as long as treatment is continued. HRT is not prescribed by the herbal practitioner. Soya and Hops are a mild alternative.

Side-effects of such treatment include blood pressure rise, weight gain and periods probably continue with a monthly bleed. Elderly women taking HRT for osteoporosis may develop bleeding problems, the risk of blood clot and gall bladder diseases.

Helonias has proved a useful alternative, effective in eliminating excess fluids, reducing hot flushes, and relieving that bloated feeling, thus helping the older woman to live a normal life.

Damiana. 1 heaped teaspoon leaves to each cup boiling water; infuse 5-10 minutes; strain. 1 cup 2-3 times daily for 3-6 weeks.

Sarsaparilla. 1oz (30g) root in 1 pint (500ml) water; simmer gently 20 minutes; strain. 1 cup 2-3 times daily for 3-6 weeks.

Supplementation. Daily. Vitamin E, 400iu. Vitamin B-complex (high potency). Evening Primrose oil capsules, 500mg morning and evening. Dolomite, for Calcium and Magnesium, 2 tablets morning and evening.

Note: An extensive study of breast cancer risks with HRT revealed a positive link between the risk of cancer and length of use. Risk of the disease increased with all types of women using HRT with every year of use. Pre-menstrual women were more than twice at risk. It would appear that oestrogens cannot be taken without risk.

Aortic Incompetence

See also REGURGITATION. This is the back ?ow of blood through the AORTIC VALVE of the HEART into the left ventricle, caused by an incompetent valve. The failure to close may be caused by a congenital defect or by damage from disease. The defect may be cured by surgical replacement of the damaged valve with an arti?cial valve. (See HEART, DISEASES OF.)... aortic incompetence

Joint Replacement

See ARTHROPLASTY.... joint replacement

Knee-joint Replacement

A surgical operation to replace a diseased – usually osteoarthritic – KNEE with an arti?cial (metal or plastic) implant which covers the worn cartilage. As much of the original joint as possible is retained. The operations, like hip replacements, are usually done on older people (there is some restriction of movement) and about 90 per cent are successful.... knee-joint replacement

Hip Replacement

A surgical procedure to replace all or part of a diseased hip joint with an artificial substitute. The replacement is most often carried out in older people whose joints are stiff and painful as a result of osteoarthritis. It may also be needed if rheumatoid arthritis has spread to the hip joint or if the top end of the femur is badly fractured (see femur, fracture of).... hip replacement

Hip Replacement Operation

Athroplasty. Success rate: high. Commonest indication: osteo- arthritis of hip. A lesser risk of sepsis occurs in first operation than in subsequent ones. Infection is suspected when acetabular loosening is present in conjunction with femoral loosening. Echinacea is the key remedy for combatting infection and for enhancing the patient’s resistance. Comfrey root promotes healing of bone tissue. St John’s Wort gives partial relief in post-operative pain. Horsetail is a source of readily absorbable iron and calcium. For slow healing, a liver agent (Fringe Tree) may be indicated. Alternatives. Teas. Comfrey leaves, Calendula, St John’s Wort, Gotu Kola, Plantain.

Tablets/capsules. St John’s Wort.

Formula. Comfrey root 2; St John’s Wort 1; Echinacea 2; trace of Cayenne (Capsicum). Dose – Powders: 750mg (three 00 capsules or half a teaspoon). Liquid Extracts: 1-2 teaspoons. Tinctures: 1-3 teaspoons. Effect is enhanced when doses are taken in cup of Comfrey herb tea. Other agents to promote renewal of tissue. Slippery Elm bark, Fenugreek seeds, Wild Yam, Carragheen Moss.

Discomfort from a scar. Aloe Vera gel, Calendula, Comfrey or Chickweed cream or ointment. See: CASTOR OIL PACK.

Diet. High protein, oily fish or fish oils.

Supplements. Vitamin C: 3-6g daily. Calcium ascorbate, Zinc. Magnesium. Cod Liver oil for Vitamins A and D; 2 teaspoons daily.

Note: Where titanium alloy implants are used for this operation serum levels of the metal are likely to show up higher than normal. Raised serum titanium has been linked with lung cancer, osteoporosis, and platelet suppression. A New Zealand study has found deaths from cancer were significantly higher in patients having had a metal hip replacement. See: CHELATION.

Comfrey. Potential benefit far outweighs possible risk. ... hip replacement operation

Finger-joint Replacement

A surgical procedure in which one or more artificial joints made of metal, plastic, or silicone rubber are used to replace finger joints destroyed by disease, usually rheumatoid arthritis or osteoarthritis.

The procedure is usually successful in relieving arthritic pain and enabling the patient to use his or her hands again, but it rarely restores normal movement.... finger-joint replacement

Nicotine Replacement Therapy

Preparations containing nicotine that are used in place of cigarettes as an aid to stopping smoking.

Nicotine products are available in the form of sublingual tablets, chewing gum, skin patches, nasal spray, or inhaler.

Side effects may include nausea, headache, palpitations, cold or flu-like symptoms, hiccups, and vivid dreaming.

Nicotine replacement therapy should be used as part of a complete package of measures, including the determination to succeed.... nicotine replacement therapy

Valve Replacement

A surgical operation to replace a defective or diseased heart valve. (See also heart-valve surgery.)... valve replacement

Aortic Aneurysm

see aneurysm.... aortic aneurysm

Aortic Arch

that part of the aorta that extends from the ascending aorta, upward over the heart and then backward and down as far as the fourth thoracic vertebra. *Stretch receptors in its outer wall monitor blood pressure and form part of the system maintaining this at a constant level.... aortic arch

Aortic Regurgitation

a leak of the aortic valve resulting in reflux of blood from the aorta into the left ventricle during diastole. Aortic regurgitation is most commonly due to degenerative ‘wear and tear’ of the aortic valve. Other causes include dilatation of the aortic root with secondary dilatation of the aortic valve, scarring of the aortic valve as a result of previous acute rheumatic fever, or destruction of the valve by infection (see endocarditis). Mild cases are symptom-free, but patients more severely affected develop breathlessness, angina pectoris, and enlargement of the heart; all have a diastolic murmur. A badly affected valve may be replaced surgically with a prosthesis.... aortic regurgitation

Bladder Replacement

see cystectomy.... bladder replacement

Pancreatic Enzyme Replacement Therapy

(PERT) a therapeutic approach using supplements of the digestive enzymes lipase, amylase, and protease (Creon, Pancrex), which are given when there is insufficient endogenous production of pancreatic enzymes: for example, to patients with pancreatic cancer or cystic fibrosis. The capsules must be taken with all meals and snacks to be effective. PERT treats the symptoms of *steatorrhoea.... pancreatic enzyme replacement therapy

Replacement Bone

a bone that is formed by replacing cartilage with bony material.... replacement bone

Transcatheter Aortic Valve Implantation

(TAVI) replacement of the aortic valve in patients with *aortic stenosis using a catheter-delivered prosthesis rather than open heart surgery. Usually the catheter is passed via the femoral artery, but sometimes it can be passed via the subclavian artery or through the wall of the left ventricle via a localized *thoracotomy.... transcatheter aortic valve implantation
