Wolff–chaikoff Effect: From 1 Different Sources


the inhibition of thyroid hormone production by administration of large doses of iodide. This occurs at a critical dosage level below which the addition of iodide to an iodine-deficient individual results in increased production of thyroid hormone. The effect is transient in individuals with normal thyroids but may persist in thyroiditis; it can be utilized medically to induce a hypothyroid state, for example in patients with *thyroid crisis (see Lugol’s solution).

Doppler Effect

A change in the frequency with which sound waves from a given source reach an observer when the source is in rapid motion with respect to the observer.

Approaching sounds appear higher in pitch (frequency) than sounds that are moving away.

This is because the wavelengths of the sound from an approaching source are progressively foreshortened, whereas the wavelengths from a receding source are stretched.

The Doppler effect is used in ultrasound scanning techniques.

An emitter sends out pulses of ultrasound (inaudible highfrequency sound) of a specific frequency.

When these pulses bounce off a moving object (blood flowing through a blood vessel, for example), the frequency of the echoes is changed from that of the emitted sound.

A sensor detects the frequency changes and converts the data into useful information (about how fast the blood flows, for example).

Doppler ultrasound techniques are also used to monitor fetal heartbeat, to detect air bubbles in dialysis and heart–lung machines, and to measure blood pressure.... doppler effect

However, high dosages may lead to hallucinations, paranoia and other severe conditions of the nervous system.

Sunlight, Adverse Effects Of

Problems resulting from overexposure to sunlight. Fair-skinned people are more susceptible. Short-term overexposure causes sunburn and, in intense heat, can result in heat exhaustion or heatstroke. Repeated overexposure over a long period can cause premature aging of the skin and solar keratoses. It increases the risk of skin cancer. Protection of the skin with sunscreens helps to prevent sun damage. Photosensitivity is an abnormal sensitivity to sunlight, resulting in a rash.

Exposure to sunlight can affect the eyes, causing irritation of the conjunctiva, actinic keratopathy, or pterygium.

Good sunglasses help to prevent eye problems.... sunlight, adverse effects of

Doctrine Of Double Effect

the principle that, where it is foreseen that a single action will have both a good and a bad outcome, a person may perform such an action provided that (a) he or she intends only the positive outcome, (b) the bad outcome is not disproportionate to the good, and (c) the good outcome is not a direct consequence of the bad. The classic example occurs where a terminally ill patient requires high doses of opiates for pain relief that may also depress respiratory function and hasten his or her death. In such a case the law holds that the doctor may supply the necessary dosage without this being considered tantamount to *euthanasia, even though the outcome will be the same, i.e. the morality of the action does not lie in its consequences (see consequentialism).... doctrine of double effect

Effectiveness And Efficiency

n. measures that are used in health economics and ethics to assess treatments of all kinds. A treatment that works or achieves its object is effective, but may do so at great cost. If it is also efficient, it achieves its aim equally but at lower cost (or consumes less resources) when compared with other treatments. Such an assessment may be part of an *intervention study. Even apparently effective and efficient treatments may work for patients only by depriving others of similar care (opportunity costs), so a moral evaluation must take into account the overall aims and purposes of health care in general.... effectiveness and efficiency

Wolff–parkinson–white Syndrome

a congenital abnormality of heart conduction caused by the presence of an *accessory pathway of conduction between the atria and ventricles. It results in premature excitation of one ventricle and is characterized by an abnormal wave (delta wave) at the start of the QRS complex on the electrocardiogram. The accessory pathway predisposes the patient to episodes of fast heart rate due to the rapid self-sustaining circulation of an electrical impulse from the atria to the ventricles and back again (*atrioventricular reciprocating tachycardia). Emergency treatment is in the form of drugs that temporarily block the re-entry circuit. Permanent destruction of the accessory pathway by *radiofrequency ablation is usually curative. [L. Wolff; Sir J. Parkinson (1885–1976), British physician; P. D. White (1886–1973), US cardiologist]... wolff–parkinson–white syndrome
