Chilblains (also known as pernio and perniosis[1]:25) is a medical condition that is often confused with frostbite and trench foot. Chilblains are acral ulcers (that is, ulcers affecting the extremities) that occur when a predisposed individual is exposed to cold and humidity. The cold exposure damages capillary beds in the skin, which in turn can cause redness, itching, blisters, and inflammation.[2] Chilblains are often idiopathic in origin but can be manifestations of serious medical conditions that need to be investigated. Chilblains can be prevented by keeping the feet and hands warm in cold weather. A history of chilblains is suggestive of a connective tissue disease.

Contents

Symptoms

  • Ulceration of the digits and toes
  • Red nose
  • Skin redness
  • Toe skin inflammation
  • Finger skin inflammation
  • Earlobe inflammation

Duration

With treatment, chilblains usually heal within 7–14 days.

Treatments

  • Keep area warm
  • Nifedipine may be used in more severe or recurrent cases.[3] Its vasodilation helps reduce pain, facilitate healing and prevent recurrences.[4]
  • Diltiazem, a newer calcium channel blocker, may also be used.[5]

Prevention

Exposure

  • Avoid rapid changes in temperature.
  • Wear gloves and socks.
  • Use warm footwear.
  • Keep hands and feet warm.
  • Avoid tight fitting socks/shoes
  • Place cotton wool between the toes to improve circulation

Dietary

  • Healthy diet
  • Exercise to improve circulation
  • High doses of vitamin K
  • Avoid alcohol before going out in snow

History

The medieval Bald's Leechbook recommended that chilblains be treated with a mix of eggs, wine, and fennel root.[6]

From LoveToKnow 1911

CHILBLAINS (or Kibe; Erythema pernio), a mild form of frostbite, affecting the fingers or toes and other parts, and causing a painful inflammatory swelling, with redness and itching of the affected part. The chief points to be noticed in its aetiology are (1) that the lesions occur in the extremities of the circulation, and (2) that they are usually started by rapid changes from heat to cold or vice versa. The treatment is both general and local. In the general treatment, if a history of blanching fingers (fingers or hands going "dead") can be obtained, the chilblains may be regarded as mild cases of Raynaud's disease, and these improve markedly under a course of nitrites. Cardiac tonics are often helpful, especially in those cases where there is some attendant lesion of the heart. But the majority of cases improve wonderfully on a good course of a calcium salt, e.g. calcium lactate or chloride; fifteen grains three times a day will answer in most cases. The patient should wash in soft tepid water, and avoid extremes of heat and cold. In the local treatment, two drugs are of great value in the early congestive stage - ichthyol and formalin. Ichthyol, 10 to 20% in lanoline spread on linen and worn at night, often dispels an attack at the beginning. Formalin is equally efficacious, but requires more skill in its use. It can be used as an ointment, io to 50% for delicate skins, stronger for coarser skins. It should be replaced occasionally by lanoline. If the stage of ulceration has been reached, a paste made from the following prescription, spread thickly on linen and frequently changed, soon cures: - Hydrarg. ammoniat. gr. v., ichthyol 111x, pulveris zinci oxidi 3 iv, vaseline ss.
