Gene therapy is currently used to treat disorders caused by a fault in a single recessive gene, when the defect can remedied by introducing a normal ALLELE. Treating disorders caused by dominant genes is more complicated. CYSTIC FIBROSIS is an example of a disease caused by a recessive gene, and clinical trials are taking place on the e?ectiveness of using LIPOSOMES to introduce the normal gene into the lungs of someone with the disorder. Trials are also underway to test the e?ectiveness of introducing tumour-suppressing genes into cancer cells to check their spread.
Gene therapy was ?rst used in 1990 to treat an American patient. Eleven European medical research councils (including the UK’s) recommended in 1988 that gene therapy should be restricted to correcting disease or defects, and that it should be limited to somatic cells. Interventions in germ-line cells (the sperm and egg) to e?ect changes that would be inherited, though technically feasible, is not allowed (see CLONING; HUMAN GENOME).... gene therapy
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.

Ionising radiation comprises X-RAYS, GAMMA RAYS and particle radiation. X-rays are part of the continuous electromagnetic-wave spectrum: this also includes gamma rays, infra-red radiation, ultraviolet light and visible light. They have a very short wavelength and very high frequency, and their ability to penetrate matter depends upon the electrical energy generating them. X-rays that are generated by 100,000 volts can pass through body tissue and are used to produce images – popularly known as X-rays. X-rays, generated at several million volts can destroy tissue and are used in RADIOTHERAPY for killing cancer cells. Gamma rays are similar to X-rays but are produced by the decay of radioactive materials. Particle radiation, which can be produced electrically or by radioactive decay, comprises parts of atoms which have mass as well as (usually) an electrical charge.
Non-ionising radiation includes ultraviolet light, radio waves, magnetic ?elds and ULTRASOUND. Magnetic ?elds are used in magnetic resonance imaging (MRI) and ultrasound, which is inaudible high-frequency sound waves, and is used for both diagnoses and treatment in medicine.... radiation
Research has shown that cognitive therapy is very e?ective in depression and that it can also help in anxiety, OBSESSIVE COMPULSIVE DISORDER, and EATING DISORDERS such as anorexia and bulimia nervosa. This therapy is also proving useful in helping people cope with HALLUCINATIONS and other symptoms of SCHIZOPHRENIA.... cognitive behaviour therapy
Before treatment, the patient will have been fasted for at least eight hours. After checking for any potential drug ALLERGY or interactions, the patient is given a general anaesthetic and muscle relaxants. Depending on the side of the patient’s dominance, either unilateral (on the side of the non-dominant hemisphere of the BRAIN) or bilateral (if dominance is uncertain,
e.g. in left-handed people) positioning of electrodes is used. Unilateral ECT has the advantage of being associated with less anterograde AMNESIA. When the current passes, the muscles will contract for approximately 10 seconds, with further tonic spasms lasting up to a minute. The patient should then be put in the COMA or recovery position and observed until fully conscious. Up to 12 treatments may be given over a month, improvement usually showing after the third session. Widely used at one time, the treatment is now given only rarely. It can be extremely frightening for patients and relatives and is not recommended for children.... electroconvulsive therapy (ect)

In 1997 the Royal College of Psychiatrists in the UK produced a comprehensive report which was sceptical about the notion that the awareness of recurrent severe sexual abuse in children could be pushed entirely out of consciousness. The authors did not believe that events could remain inaccessible to conscious memory for decades, allegedly provoking vague non-speci?c symptoms to be recovered during psychotherapy with resolution of the symptoms. Supporting evidence pointed to the lack of any empirical proof that unconscious dissociation of unpleasant memories from conscious awareness occurred to protect the individual. Furthermore, experimental and natural events had shown that false memories, created through suggestion or in?uence, could be implanted. Many individuals who had claimed to have recovered memories of abuse subsequently withdrew and, often, non-speci?c symptoms allegedly linked to suppression worsened rather than improved as therapy to unlock memories proceeded. The conclusion is that recovered memory therapy should be viewed with great caution.... repressed memory therapy

Basically, the therapy consists of a vegetarian diet with meals of vegetables, fruits and whole grains, fresh or freshly prepared. Drinking water is replaced by hourly, fresh, raw juices of vegetables and fruits. Refined, altered, denatured or enhanced foodstuffs are forbidden. The diet is sodium, chloride, fat and protein restricted. Supplemental potassium, iodine, thyroid and crude liver extract comprise the medical armamentarium. A repeatable choleretic, enemas of a solution of boiled coffee, is administered to lower serum toxin levels. Coffee is a potent enhancer of the carcinogen detoxifying enzyme system, glutathione S-translerase (Wattenburg). The Gerson cancer therapy reduces accumulated tissue sodium and chloride, promoting diuresis. Gerson Therapy Center: Hospital de Baja California, at La Gloria, Mexico
Diet. Lunch and dinner contain ample cooked food, mainly to act as a ‘blotter’ to the daily intake of 5.25 pints fresh raw fruit juices that are the backbone of the therapy. Ingredients of the juices include 41bs raw organic carrots a day, with no harm to the liver. (JAM, May 1991, p5. Beata Bishop on her recovery from metastasised malignant melanoma)
The Gerson therapy is based on the ‘holistic’ philosophy which states that cancer represents a clinical manifestation of an underlying toxic condition. Such condition should receive primary treatment that is lifestyle orientated. The theme is: detoxification through internal cleansing. The diet and supplements are re-inforced by ‘positive thinking’ and supported by meditation and emotional balance. ... gerson cancer therapy

The amount of fluid necessary depends on age, weight, and the degree of dehydration.
Mild dehydration can usually be treated with oral solutions, which are available as effervescent tablet or powder to be made up at home.
In severe dehydration, or if the patient cannot take fluids by mouth because of nausea or vomiting, an intravenous infusion of saline and/or glucose solution may be given in hospital.... rehydration therapy
They work by blocking the reabsorption of the neurotransmitter serotonin following its release in the brain.
The increased serotonin levels that result are associated with improved mood.
Common drugs in this group include fluoxetine and sertraline.
SSRIs are usually taken orally once a day; it may take 1–3 weeks for any noticeable improvement in symptoms.
SSRIs usually produce fewer side effects than other types of antidepressant drug.
However, they may cause diarrhoea, nausea, restlessness, and anxiety.... selective serotonin reuptake inhibitors
The technique may be used to treat a malignant effusion (a collection of fluid that contains cancerous cells). A needle, sometimes with a catheter attached, is passed through the wall of the abdomen or the chest into the abdominal cavity or pleural cavity (the space around the lungs). As much of the fluid as possible is withdrawn from the cavity before anticancer drugs are injected directly into it. (See also interstitial radiotherapy.)... intracavitary therapy
With some forms of radiation, damage occurs when the radiation dose exceeds a certain limit, usually 1 sievert (Sv) (see radiation unit). This damage may include radiation dermatitis, cataracts, organ failure (which may occur many years later), or radiation sickness.
For other types of radiation damage, the risk that damage will occur increases with increasing doses of radiation. Cancer caused by radiation-induced mutation is the major example of this type of damage. Radioactive leaks from nuclear reactors can cause a rise in mutation rates, which may lead to an increase in cancers, such as leukaemias; to birth defects; and to hereditary diseases. Cancer usually develops years after exposure. Radiation damage can be controlled by limiting exposure. People exposed to radiation at work have their exposure closely monitored to ensure that it does not exceed safe limits. People of reproductive age or younger should have their reproductive organs shielded when having X-rays or radiotherapy.There is no evidence of radiation hazards with visual display units (VDUs).... radiation hazards
The gray is the unit of radiation that is actually absorbed by any tissue or substance as a result of exposure to radiation. 1 Gy is the absorption of 1 joule of energy (from gamma radiation or X-rays) per kilogram of irradiated matter. The gray supersedes an older unit called the rad (1 Gy = 100 rads).
Because some types of radiation affect biological organisms more than others, the sievert is used as a measure of the impact of an absorbed dose. It uses additional factors, such as the kind of radiation and its energy, to quantify the effects on the body of equivalent amounts of different types of absorbed energy. The sievert replaces an older unit, the rem (1 Sv=100 rems).... radiation unit
