Sudamen.
Оглавление(Synonym: Miliaria crystallina.)
What is sudamen?
Sudamen is a non-inflammatory disorder of the sweat-glands, characterized by pin-point to pin-head-sized, discrete but thickly-set, superficial, translucent whitish vesicles.
Describe the clinical characters.
The lesions develop rapidly and in great numbers, either irregularly or in crops, and are usually to be seen as discrete, closely-crowded, whitish, or pearl-colored minute elevations, occurring most abundantly upon the trunk. In appearance they resemble minute dew-drops. They are non-inflammatory, without areola, never become purulent, and evince no tendency to rupture, the fluid disappearing by absorption, and the epidermal covering by desquamation.
Give the course and duration of sudamen.
New crops may appear as the older lesions are disappearing, and the affection persist for some time, or, on the other hand, the whole process may come to an end in several days or a week. In short, the course and duration depend upon the subsidence or persistence of the cause.
What is the anatomical seat of sudamen?
The lesions are formed between the lamellæ of the corneous layer, usually the upper part; and are thought to be due to some change in the character of the epithelial cells of this layer, probably from high temperature, giving rise to a blocking up of the surface outlet.
What is the cause of sudamen?
Debility, especially when associated with high fever. The eruption is often seen in the course of typhus, typhoid and rheumatic fevers.
How would you treat sudamen?
By constitutional remedies directed against the predisposing factor or factors, and the application of cooling lotions of vinegar or alcohol and water, or dusting-powders of starch and lycopodium.
