Definition
This section has been translated automatically.

Frequent abnormal tissue reaction occurring in persons with the appropriate disposition, with reversible and very changeable inflammatory skin changes, which can occur even with moderate exposure to cold.

Etiopathogenesis
This section has been translated automatically.

Mostly vegetatively disturbed vascular function with insufficient adaptation to external temperature conditions (outside temperatures slightly above 0 °C, especially in cold and wet climates, also in cold humid work, e.g. in butchery professions), but also in local or systemic infections (tuberculosis patients).

Manifestation
This section has been translated automatically.

Occurs mainly in female adolescents or adults with acrocyanosis. Frequently there is general obesity or pasty habitus. Seasonal accumulation mainly in spring and autumn. Occurrence in connection with occupational exposure to cold (butchers, cold store workers, soldiers) or in homeless people is not uncommon. Increasingly, frostbite is occurring among alpinists.

Localization
This section has been translated automatically.

Dorsal sides of the fingers and toes, lower leg, knee area.

Clinical features
This section has been translated automatically.

In the interval little conspicuous, laminar, livid redness, which changes to blue-reddish, possibly blue or reddish-brown (purple component), pasty, sometimes painless but also clearly painful plaques or nodules when the temperature changes. The duration of the changes varies, ranging from hours to several days to weeks. Itching or burning may occur when the skin warms up. Blistering and ulceration are possible. S.a. Perniosis follicularis, spring perniosis, autumn perniosis.

Notice! An apparently healthy red complexion can be an expression of chronic cold damage.

Histology
This section has been translated automatically.

Capillary dilatation exists in the corium. Edema is detectable in the upper corium. Larger vessels are wall thickened and filled with thrombi. Lymphohistiocytic infiltrates are perivascular.

Differential diagnosis

Complication(s)
This section has been translated automatically.

Secondary infections, ulcerations, scars.

External therapy
This section has been translated automatically.

In the acute phase supply of heat and/or hyperemic ointments. In case of strong inflammatory symptoms, short-term potent glucocorticoid extracts such as 0.05% clobetasol cream (e.g. R054, dermoxin), 0.1% mometasone cream (e.g. Ecural), if necessary under occlusion.

Internal therapy
This section has been translated automatically.

  • Systemic therapy can be considered in the case of very pronounced clinical symptoms, e.g. with interval therapy with iloprost (0.5-2.0ng/kgKG/min.
  • Furthermore, a trial with pentoxifylline (e.g. Trental) 2 times/day 400 mg p.o. can be initiated.

Progression/forecast
This section has been translated automatically.

Very variable course; recurrences with exposure to cold. Improvement at a higher age is possible.

Prophylaxis
This section has been translated automatically.

Especially in the transitional seasons, protection against cold and wetness by wearing suitable clothing, warm shoes! Use of pocket ovens! Active vascular training in the sauna, Kneipp cures, underwater massages, foot baths with alternating temperatures, sports.

Phytotherapy external
This section has been translated automatically.

Benedictine herb used to be used externally, see Cnici benedicti herba,

in empirical medicine also Fagopyri herba and Ratanhiae radix
