These are:
Quotidian fever, with a 24-hour periodicity, typical of malaria caused by Plasmodium knowlesi (P. knowlesi);
Tertian fever, with a 48-hour periodicity, typical of later course malaria caused by P. falciparum, P. vivax, or P. ovale;
Quartan fever, with a 72-hour periodicity, typical of later course malaria caused by P. malariae.In addition, there is disagreement regarding whether a specific fever pattern is associated with Hodgkins lymphoma—the Pel–Ebstein fever, with patients argued to present high temperature for one week, followed by low for the next week, and so on, where the generality of this pattern is debated.Persistent fever that cannot be explained after repeated routine clinical inquiries is called fever of unknown origin. A neutropenic fever, also called febrile neutropenia, is a fever in the absence of normal immune system function. Because of the lack of infection-fighting neutrophils, a bacterial infection can spread rapidly; this fever is, therefore, usually considered to require urgent medical attention. This kind of fever is more commonly seen in people receiving immune-suppressing chemotherapy than in apparently healthy people. Hyperpyrexia
Hyperpyrexia is an extreme elevation of body temperature which, depending upon the source, is classified as a core body temperature greater than or equal to 40 or 41 °C (104 or 106 °F); the range of hyperpyrexias includes cases considered severe (≥ 40 °C) and extreme (≥ 42 °C). It differs from hyperthermia in that ones thermoregulatory systems set point for body temperature is set above normal, then heat is generated to achieve it.
Painful fat herniation is foot pain caused by the herniation of fat through the thin fascial layers of the weight-bearing parts of the heel. The herniation results in small bumps called piezogenic pedal papules or piezogenic papules. Though piezogenic papules are most commonly found on the heel, they can also be found on the wrist and palm.Piezogenic papules are relatively common; in one population-based study, the prevalence was found to be 76%. They occur more frequently in runners, triathletes, and individuals exposed to long periods of standing. They are also common in individuals with connective tissue disorders, especially Ehlers–Danlos syndrome. However, due to their preponderance in the general population, the presence of piezogenic papules alone does not automatically indicate the presence of Ehlers–Danlos syndrome. In most cases, piezogenic papules are of little clinical significance. See also
