Dr. Rogers adds that there are three types of heat rash, the most common being miliaria crystallina.

The more severe kind of heat rash is called miliaria rubra, or "Prickly Heat," Dr. Rogers says.

"Heat rash" is sort of a catchall, layman's term for a medical condition called miliaria, which is a "skin eruption that develops after being too hot," says Heather Rogers, MD, a dermatologist in Seattle.

Miliaria pustulosa describes pustules due to inflammation and bacterial infection. Miliaria pustulosa is preceded by another dermatitis that has produced injury, destruction, or blocking of the sweat duct.

The most superficial obstruction (with the most mild clinical presentation), is known as miliaria crystalline; instead of a rash, the patient presents with multiple tiny blister-like lesions that look like beads of perspiration and essentially cause no symptoms. Miliaria crystalline is also known as "Miliaria crystallina," and "Sudamina". The superficial vesicles are not associated with an inflammatory reaction.

The most severe form of miliaria, miliaria profunda, sometimes referred to as "wildfire" due to the rapid spread and severe burning sensations, generally occurs as a complication of repeated episodes of miliaria rubra. The obstruction is deep in the structure of the sweat gland, causing the gland's secretions to leak between the superficial and deep layers of the skin. The rash, and associated symptoms, tend to appear within hours of an activity provoking sweating but similarly fade within hours when the stimulus for the sweating is removed. Miliaria profunda is characterised by non-pruritic, flesh-coloured, deep-seated, whitish papules.

Miliaria can be classified according to the top level at which obstruction occurs in the sweat glands.

Ramon Lull's miliaria in mari, from his 1295 example. : Miliaria in mari = distance sailed × cos(θ) where θ is the angle of difference between the two routes. Using Lull's example, a ship that intended to sail southeast ("Exaloch" is Catalan for "Scirocco") but was instead forced to sail east ("Levant"), then the angle of difference is θ = 45°. After 100 miles on the erroneous route, the miliaria on the intended route is 100 × cos 45° = 70.71. Doubling the sailing on the erroneous route to 200 miles will double the miliaria on the intended route to 141.42 miles (= 200 cos 45°). (Diagramatically, Lull's miliaria in mari is measured by constructing a right- angled triangle by running a cord from the distance sailed on the actual course to the intended course, meeting the latter at a 90° angle). Llull is a little more explicit in his Ars magna generalis et ultima (written c. 1305).Ramom Llull, 1517 ed.

Miliaria, also called "sweat rash", is a skin disease marked by small and itchy rashes due to sweat trapped under the skin by clogged sweat gland ducts. Miliaria is a common ailment in hot and humid conditions, such as in the tropics and during the summer season. Although it affects people of all ages, it is especially common in children and infants due to their underdeveloped sweat glands.

The symptoms relating to miliaria should not be confused with shingles as they can be very similar. Shingles will restrict itself to one side of the body but also has a rash-like appearance. It is also accompanied by a prickling sensation and pain throughout the region. Those who suspect they have shingles and not miliaria should seek medical advice immediately as the sooner antivirals are taken, the better.

Occlusion miliaria is a skin condition that is accompanied by anhidrosis and increased heat-stress susceptibility, all after the application of extensive polyethylene film occlusion for 48 hours or longer.

The differential diagnosis includes several conditions that an experienced practitioner should be able to recognise and may require treatment distinct from the usual measures taken for miliaria. In most cases, the rash of miliaria will resolve without intervention. However, severe cases can last for weeks and cause significant disability. General measures should be recommended for all patients, including moving to an air-conditioned environment if possible, avoiding sweat-provoking activities and occlusive clothing, and taking frequent cool showers.

Tolazoline (Priscoline) has been shown to offer symptomatic relief from sympathetic overactivity.Antibiotics are necessary when massive hyperhidrosis, which may rapidly lead to miliaria rubra, is present. This can easily progress to bacterial secondary infection with a tendency for ulcerating pyoderma.

Modern Beniane corresponds to the ancient city of Ala Miliaria in the Roman province of Mauretania Caesariensis, which was important enough to be one of the many suffragans of the capital Caesarea Mauretaniae's Metropolitan Archbishopric. It was the episcopal see of Mensius, one of the Catholic bishops whom the Arian Vandal king Huneric summoned to Carthage in 484 and then exiled. Archaeological excavations in the early 20th century brought to light inscriptions showing that there was a strong Donatist presence in Ala Miliaria, with bishops named Nemessanus (404-422) and Donatus (c. 439).J. Mesnage, L'Afrique chrétienne, Paris 1912, p.

Non-infectious skin conditions may also occur including miliaria, immersion foot syndrome (including trench foot), and contact dermatitis. Earthquake-associated injuries The predominant injuries are related to building structural components, including falling debris with possible crush injury, burns, electric shock, and being trapped under rubble.

Cope's brown treefrog or fringe-limbed treefrog (Ecnomiohyla miliaria) is a species of frog in the family Hylidae. It is found in Costa Rica, Nicaragua, and Panama. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss.

In 1658, the locality was burned, following a Turkish and Tatar invasion. In the 18th century, a milestone named Aiton Biliar from the Roman period was discovered. This marked a distance on the Potaissa-Napoca. The landmark attests the existence of a road built in 108 AD by the cohors I hispanorum miliaria.

The most commonly encountered form of the illness is miliaria rubra, in which obstruction causes leakage of sweat into the deeper layers of the epidermis, provoking a local inflammatory reaction and giving rise to the typical appearance of redness (hence rubra) and larger (but still only a few millimetres), blister-like lesions. This form of the illness is often accompanied by the typical symptoms—intense itching or "pins and needles" with a lack of sweating (anhidrosis) to affected areas. There is a small risk of heat exhaustion due to inability to sweat if the rash affects a large proportion of the body's surface area or the sufferer continues to engage in heat-producing activity. Miliaria rubra is also known as prickly heat and heat rash.

Milestones (miliaria) have already been referred to, and may be regarded as records of the building of roads. Boundary stones (termini) are frequently found, both of public and private property. A well-known instance is offered by those set up by the commissioners called III. viri A.I.A. (agris iudicandis adsignandis) in the time of the Gracchi.

There are two known bishops of this ancient diocese. Honoratus who represented the Donatists at the Council of Carthage (411). The grave of his sister Robba, revered as a martyr by the Donatists, was found in Ala Miliaria recently. The other Bishop, Felix was among the Catholic prelates summoned to Carthage in 484 by the Vandal king Huneric.

Miliaria occurs when the sweat gland ducts get clogged due to dead skin cells or bacteria such as Staphylococcus epidermidis, a common bacterium that occurs on the skin which is also associated with acne. The trapped sweat leads to irritation (prickling), itching and to a rash of very small blisters, usually in a localized area of the skin.

The primary remedy for prickly heat or rash is to wear lighter clothing, or otherwise avoid overheating one's body. The immediate treatment of the involved skin areas involves the use of a soothing ointment such as calamine lotion. Talcum powder may be used in some cases. Medical assistance should be sought for the first episode of a rash with the appearance of miliaria.

The scholar-cleric Ramon Llull of Majorca, was the first writer to refer to a rule to solve the traverse problem of navigation. In his Arbor Scientiae (1295), in the section of questions on geometry, Llul writes: What Llull seems to be trying to explain is that a ship actually sailing E, but intending to sail SE, it can figure out how much of its intended southeastward distance it has already made good – what Italians called the "avanzar", but Lull seems to call the "miliaria in mari". Llull does not explain exactly how, but refers only to an "instrument", presumably some sort of trigonometric table. Lull is implying that mariners can calculate the miliaria on the intended course by multiplying the distance actually sailed on the erroneous course by the cosine of the angle between the two routes.This interpretation is originally due to Taylor (1956: pp. 117–19).

In most tropical areas the local dispensaries sell prickly heat powder, a talc admixture containing drying milk proteins (Labilin) and Triclosan to fight the infection. These include cooling menthol to help alleviate difficulty getting to sleep. This is an effective treatment—the powder stays on the skin longer and treats bacteria dispersed into bed linens, providing a reasonably dry refuge area for healing. Miliaria often covers large areas, and generous use of Cortisone may be contraindicated for reasons stated on package warnings.

Symptoms of miliaria include small red rashes, called papules, which are irritated and itchy. These may simultaneously occur at a number of areas on a sufferer's body, the most common including the upper chest, neck, elbow creases, under the breasts and under the scrotum. Other areas include skin folds, areas of the body that may rub against clothing, such as the back, chest, and stomach. A related and sometimes simultaneous condition is folliculitis, where hair follicles become plugged with foreign matter, resulting in inflammation.

These were the crested bunting (Melophus lathami), the slaty bunting (Latouchiornis siemsseni), and the corn bunting (Miliaria calandra). All three species are now included in the genus Emberiza. A large DNA-based study of the passerines published in 2019 found that the buntings are most closely related to the longspurs and snow buntings in the family Calcariidae. Ornithologists Edward Dickinson and Leslie Christidis in the fourth edition of the Howard and Moore Complete Checklist of the Birds of the World chose to split up Emberiza and recognise the genera Fringillaria, Melophus, Granativora, Emberiza, and Schoeniclus.

In 1890, Morvan described a patient with myokymia (muscle twitching) associated with muscle pain, excessive sweating, and disordered sleep. This rare disorder is characterized by severe insomnia, amounting to no less than complete lack of sleep (agrypnia) for weeks or months in a row, and associated with autonomic alterations consisting of profuse perspiration with characteristic skin miliaria (also known as sweat rash), tachycardia, increased body temperature, and hypertension. Patients display a remarkable hallucinatory behavior, and peculiar motor disturbances, which Morvan reported under the term “fibrillary chorea” but which are best described in modern terms as neuromyotonic discharges. The association of the disease with thymoma, tumour, autoimmune diseases, and autoantibodies suggests an autoimmune or paraneoplastic aetiology.

It has been suggested that the use of topical antibacterials (including antibacterial soaps) may shorten the duration of symptoms in miliaria rubra even in the absence of obvious superinfection. Other topical agents that may reduce the severity of symptoms include anti-itch preparations such as calamine or menthol- or camphor-based preparations, and topical steroid creams. However, caution should be used with oil-based preparations (ointments and oily creams as opposed to water-based or aqueous lotions) that may increase blockage to the sweat glands and prolong the duration of illness. Other agents have been investigated including supplemental vitamin A and C and vitamin A based medications, but it is worth noting that there is little scientific evidence supporting any of the above treatments in reducing the duration of symptoms or frequency of complications.

The boiler containing hot water was placed immediately over the furnace; as the water was drawn out from there, it was supplied from the next, the tepidarium, which was raised a little higher and stood a little way off from the furnace. It was already considerably heated from its contiguity to the furnace and the hypocaust below it, so that it supplied the deficiency of the former without materially diminishing its temperature; and the vacuum in this last was again filled up from the farthest removed, which contained the cold water received directly from the square reservoir seen behind them. The boilers themselves no longer remain, but the impressions which they have left in the mortar in which they were embedded are clearly visible, and enable us to determine their respective positions and dimensions. Such coppers or boilers appear to have been called miliaria, from their similarity of shape to a milestone.Pallad. i.
