Familial Mediterranean Fever: From 1 Different Sources
An inherited condition that affects certain Sephardic Jewish, Armenian, and Arab families. Its cause is unknown. Symptoms usually begin between the ages of 5 and 15 years, and include recurrent episodes of fever, abdominal and chestpain, and arthritis. Red skin swellings sometimes occur, and affected people may also suffer psychiatric problems. Attacks usually last from 24–48 hours but may be longer. Between attacks there are usually no symptoms. Although there is no specific treatment for familial Mediterranean fever, known sufferers can reduce the incidence of attacks by taking colchicine. Death may eventually occur from amyloidosis, which is a complication of the condition.

Fever, or PYREXIA, is the abnormal rise in body TEMPERATURE that frequently accompanies disease in general.
Causes The cause of fever is the release of fever-producing proteins (pyrogens) by phagocytic cells called monocytes and macrophages, in response to a variety of infectious, immunological and neoplastic stimuli. The lymphocytes (see LYMPHOCYTE) play a part in fever production because they recognise the antigen and release substances called lymphokines which promote the production of endogenous pyrogen. The pyrogen then acts on the thermoregulatory centre in the HYPOTHALAMUS and this results in an increase in heat generation and a reduction in heat loss, resulting in a rise in body temperature.
The average temperature of the body in health ranges from 36·9 to 37·5 °C (98·4 to 99·5 °F). It is liable to slight variations from such causes as the ingestion of food, the amount of exercise, the menstrual cycle, and the temperature of the surrounding atmosphere. There are, moreover, certain appreciable daily variations, the lowest temperature being between the hours of 01.00 and 07.00 hours, and the highest between 16.00 and 21.00 hours, with tri?ing ?uctuations during these periods.
The development and maintenance of heat within the body depends upon the metabolic oxidation consequent on the changes continually taking place in the processes of nutrition. In health, this constant tissue disintegration is exactly counterbalanced by the consumption of food, whilst the uniform normal temperature is maintained by the adjustment of the heat developed, and of the processes of exhalation and cooling which take place, especially from the lungs and skin. During a fever this balance breaks down, the tissue waste being greatly in excess of the food supply. The body wastes rapidly, the loss to the system being chie?y in the form of nitrogen compounds (e.g. urea). In the early stage of fever a patient excretes about three times the amount of urea that he or she would excrete on the same diet when in health.
Fever is measured by how high the temperature rises above normal. At 41.1 °C (106 °F) the patient is in a dangerous state of hyperpyrexia (abnormally high temperature). If this persists for very long, the patient usually dies.
The body’s temperature will also rise if exposed for too long to a high ambient temperature. (See HEAT STROKE.)
Symptoms The onset of a fever is usually marked by a RIGOR, or shivering. The skin feels hot and dry, and the raised temperature will often be found to show daily variations – namely, an evening rise and a morning fall.
There is a relative increase in the pulse and breathing rates. The tongue is dry and furred; the thirst is intense, while the appetite is gone; the urine is scanty, of high speci?c gravity and containing a large quantity of solid matter, particularly urea. The patient will have a headache and sometimes nausea, and children may develop convulsions (see FEBRILE CONVULSION).
The fever falls by the occurrence of a CRISIS – that is, a sudden termination of the symptoms – or by a more gradual subsidence of the temperature, technically termed a lysis. If death ensues, this is due to failure of the vital centres in the brain or of the heart, as a result of either the infection or hyperpyrexia.
Treatment Fever is a symptom, and the correct treatment is therefore that of the underlying condition. Occasionally, however, it is also necessary to reduce the temperature by more direct methods: physical cooling by, for example, tepid sponging, and the use of antipyretic drugs such as aspirin or paracetamol.... fever

So-called because of the characteristic temperature chart showing recurring bouts of fever, this is an infectious disease caused by SPIROCHAETE. There are two main forms of the disease.
Louse-borne relapsing fever is an EPIDEMIC disease, usually associated with wars and famines, which has occurred in practically every country in the world. For long confused with TYPHUS FEVER and typhoid fever (see ENTERIC FEVER), it was not until the 1870s that the causal organism was described by Obermeier. It is now known as the Borrelia recurrentis, a motile spiral organism 10–20 micrometres in length. The organism is transmitted from person to person by the louse, Pediculus humanus.
Symptoms The incubation period is up to 12 days (but usually seven). The onset is sudden, with high temperature, generalised aches and pains, and nose-bleeding. In about half of cases, a rash appears at an early stage, beginning in the neck and spreading down over the trunk and arms. JAUNDICE may occur; and both the LIVER and the SPLEEN are enlarged. The temperature subsides after ?ve or six days, to rise again in about a week. There may be up to four such relapses (see the introductory paragraph above).
Treatment Preventive measures are the same as those for typhus. Rest in bed is essential, as are good nursing and a light, nourishing diet. There is usually a quick response to PENICILLIN; the TETRACYCLINES and CHLORAMPHENICOL are also e?ective. Following such treatment the incidence of relapse is about 15 per cent. The mortality rate is low, except in a starved population.
Tick-borne relapsing fever is an ENDEMIC disease which occurs in most tropical and sub-tropical countries. The causative organism is Borrelia duttoni, which is transmitted by a tick, Ornithodorus moubata. David Livingstone suggested that it was a tick-borne disease, but it was not until 1905 that Dutton and Todd produced the de?nitive evidence.
Symptoms The main di?erences from the louse-borne disease are: (a) the incubation period is usually shorter, 3–6 days (but may be as short as two days or as long as 12); (b) the febrile period is usually shorter, and the afebrile periods are more variable in duration, sometimes only lasting for a day or two; (c) relapses are much more numerous.
Treatment Preventive measures are more di?cult to carry out than in the case of the louse-borne infection. Protective clothing should always be worn in ‘tick country’, and old, heavily infected houses should be destroyed. Curative treatment is the same as for the louse-borne infection.... relapsing fever
An acute febrile illness, usually seen in children, which may include ARTHRALGIA, ARTHRITIS, CHOREA, carditis (see below) and rash (see ERUPTION). The illness has been shown to follow a beta-haemolytic streptococcal infection (see STREPTOCOCCUS).
Rheumatic fever is now extremely uncommon in developed countries, but remains common in developing areas. Diagnosis is based on the presence of two or more major manifestations – endocarditis (see under HEART, DISEASES OF), POLYARTHRITIS, chorea, ERYTHEMA marginatum, subcutaneous nodules – or one major and two or more minor ones – fever, arthralgia, previous attacks, raised ESR, raised white blood cell count, and ELECTROCARDIOGRAM (ECG) changes. Evidence of previous infection with streptococcus is also a criterion.
Clinical features Fever is high, with attacks of shivering or rigor. Joint pain and swelling (arthralgia) may affect the knee, ankle, wrist or shoulder and may migrate from one joint to another. TACHYCARDIA may indicate cardiac involvement. Subcutaneous nodules may occur, particularly over the back of the wrist or over the elbow or knee. Erythema marginatum is a red rash, looking like the outline of a map, characteristic of the condition.
Cardiac involvement includes PERICARDITIS, ENDOCARDITIS, and MYOCARDITIS. The main long-term complication is damage to the mitral and aortic valves (see HEART).
The chief neurological problem is chorea (St Vitus’s dance) which may develop after the acute symptoms have subsided.
Chronic rheumatic heart disease occurs subsequently in at least half of those who have had rheumatic fever with carditis. The heart valve usually involved is the mitral; less commonly the aortic, tricuspid and pulmonary. The lesions may take 10–20 years to develop in developed countries but sooner elsewhere. The heart valves progressively ?brose and ?brosis may also develop in the myocardium and pericardium. The outcome is either mitral stenosis or mitral regurgitation and the subsequent malfunction of this or other heart valves affected is chronic failure in the functioning of the heart. (see HEART, DISEASES OF).
Treatment Eradication of streptococcal infection is essential. Other features are treated symptomatically. PARACETAMOL may be preferred to ASPIRIN as an antipyretic in young children. One of the NON-STEROIDAL ANTIINFLAMMATORY DRUGS (NSAIDS) may bene?t the joint symptoms. CORTICOSTEROIDS may be indicated for more serious complications.
Patients who have developed cardiac-valve abnormalities require antibiotic prophylaxis during dental treatment and other procedures where bacteria may enter the bloodstream. Secondary cardiac problems may occur several decades later and require replacement of affected heart valves.... rheumatic fever

Fever is a medical condition characterized by the elevation of body temperature above the normal range of 36.5-37.5 °C (98-100 °F). It is normally caused by an increase in the temperature regulatory set-point, which leads to increased muscle tone and shivering.
Fever can be caused by several conditions: from benign to potentially serious issues. Treatment to reduce fever is not necessary, unless the temperature is very high. Antipyretic medications can lower the temperature.
Hydration is vital in dealing with fever.
How tea for fever works
Tea for fever is usually successful in lowering the body›s temperature.
Efficient teas for fever
Studies revealed that Echinacea tea and Anamu tea are both efficient teas for fever.
Echinacea is a herb found in the Unites States: from Texas to Alabama, and from Kansas to Nebraska.
The flowers of the Echinacea plant are whitish rose to pale purple. It has brown fruiting heads and a thick, blackish root.
Generally, it is known as an immunity enhancer.
Echinacea tea is used to treat the common cold, influenza outbreaks and mild to moderate infections of all kinds.
Echinacea beverage as a tea for fever contributes to lowering the fever, due to its anti-inflammatory action.
To prepare Echinacea tea, infuse the leaves, stems, flowers and roots of the Echinacea plant in hot water. Steep them for 15 minutes. Strain it and drink it warm.
Anamu tea is often chosen by consumers due to its anti-tumors and anti-cancer properties.
As a tea for fever, Anamu beverage helps the body to fight against infections, boosting its immune system. It enables it to reduce the high temperature.
To prepare Anamu tea, place 30 grams of the dried anamu plant in one liter of boiling water. Let it boil for 15 minutes. Take it out of the heat. Let the mix steep for a further 7 minutes. It can be taken three times a day.
Anamu can also be found in powder tablet and capsules.
Tea for fever: Side effects
In large doses, teas for fever may cause side effects: vomiting, nausea, dizziness, heartburn.
Teas for fever are good to be purchased instead of traditional drugs. They act as an immunity enhancer and may lower the fever, thus improving the general state of the patients.

An infective disease of worldwide distribution, the manifestations of which vary in di?erent localities. The causative organisms of all forms of typhus fever belong to the genus RICKETTSIA. These are organisms which are intermediate between bacteria and viruses in their properties, and measure 0·5 micrometre or less in diameter.
Louse typhus, in which the infecting rickettsia is transmitted by the louse, is of worldwide distribution. More human deaths have been attributed to the louse via typhus, louse-borne RELAPSING FEVER and trench fever, than to any other insect with the exception of the MALARIA mosquito. Louse typhus includes epidemic typhus, Brill’s disease – which is a recrudescent form of epidemic typhus – and TRENCH FEVER.
Epidemic typhus fever, also known as exanthematic typhus, classical typhus, and louse-borne typhus, is an acute infection of abrupt onset which, in the absence of treatment, persists for 14 days. It is of worldwide distribution, but is largely con?ned today to parts of Africa. The causative organism is the Rickettsia prowazeki, so-called after Ricketts and Prowazek, two brilliant investigators of typhus, both of whom died of the disease. It is transmitted by the human louse, Pediculus humanus. The rickettsiae can survive in the dried faeces of lice for 60 days, and these infected faeces are probably the main source of human infection.
Symptoms The incubation period is usually 10–14 days. The onset is preceded by headache, pain in the back and limbs and rigors. On the third day the temperature rises, the headache worsens, and the patient is drowsy or delirious. Subsequently a characteristic rash appears on the abdomen and inner aspect of the arms, to spread over the chest, back and trunk. Death may occur from SEPTICAEMIA, heart or kidney failure, or PNEUMONIA about the 14th day. In those who recover, the temperature falls by CRISIS at about this time. The death rate is variable, ranging from nearly 100 per cent in epidemics among debilitated refugees to about 10 per cent.
Murine typhus fever, also known as ?ea typhus, is worldwide in its distribution and is found wherever individuals are crowded together in insanitary, rat-infested areas (hence the old names of jail-fever and ship typhus). The causative organism, Rickettsia mooseri, which is closely related to R. prowazeki, is transmitted to humans by the rat-?ea, Xenopsyalla cheopis. The rat is the main reservoir of infection; once humans are infected, the human louse may act as a transmitter of the rickettsia from person to person. This explains how the disease may become epidemic under insanitary, crowded conditions. As a rule, however, the disease is only acquired when humans come into close contact with infected rats.
Symptoms These are similar to those of louse-borne typhus, but the disease is usually milder, and the mortality rate is very low (about 1·5 per cent).
Tick typhus, in which the infecting rickettsia is transmitted by ticks, occurs in various parts of the world. The three best-known conditions in this group are ROCKY MOUNTAIN SPOTTED FEVER, ?èvre boutonneuse and tick-bite fever.
Mite typhus, in which the infecting rickettsia is transmitted by mites, includes scrub typhus, or tsutsugamushi disease, and rickettsialpox.
Rickettsialpox is a mild disease caused by Rickettsia akari, which is transmitted to humans from infected mice by the common mouse mite, Allodermanyssus sanguineus. It occurs in the United States, West and South Africa and the former Soviet Union.
Treatment The general principles of treatment are the same in all forms of typhus. PROPHYLAXIS consists of either avoidance or destruction of the vector. In the case of louse typhus and ?ea typhus, the outlook has been revolutionised by the introduction of e?cient insecticides such as DICHLORODIPHENYL TRICHLOROETHANE (DDT) and GAMMEXANE.
The value of the former was well shown by its use after World War II: this resulted in almost complete freedom from the epidemics of typhus which ravaged Eastern Europe after World War I, being responsible for 30 million cases with a mortality of 10 per cent. Now only 10,000–20,000 cases occur a year, with around a few hundred deaths. E?cient rat control is another measure which reduces the risk of typhus very considerably. In areas such as Malaysia, where the mites are infected from a wide variety of rodents scattered over large areas, the wearing of protective clothing is the most practical method of prophylaxis. CURATIVE TREATMENT was revolutionised by the introduction of CHLORAMPHENICOL and the TETRACYCLINES. These antibiotics altered the prognosis in typhus fever very considerably.... typhus fever
