Faradization and galvanization are sometimes serviceable. Repeated mild exposures to the Röntgen rays have a favorable influence in some instances.
Sudamen.
(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.
Hydrocystoma.
Describe hydrocystoma.
Hydrocystoma is a cystic affection of the sweat-gland ducts, seated upon the face. The lesions may be present in scant numbers or in more or less profusion. They have the appearance of boiled sago grains imbedded in the skin; the larger lesions may have a bluish color, especially about the periphery. It is not common, and is usually seen in washerwomen and laundresses, or those exposed to moist heat. In some cases it tends to disappear during the winter months. There are no subjective symptoms.
Treatment consists of puncturing the lesions and application of dusting-powder. Avoidance of the exciting cause (moist heat) is important.
Anidrosis.
Describe anidrosis.
It is the opposite condition of hyperidrosis, and is characterized by diminution or suppression of the sweat secretion. It occurs to some extent in certain systemic diseases and also in some affections of the skin, such as ichthyosis; nerve-injuries may give rise to localized sweat-suppression.
Treatment is based upon general principles; friction, warm and hot-vapor baths, electricity and similar measures are of service.
Bromidrosis.
(Synonym: Osmidrosis.)
Describe bromidrosis.
Bromidrosis is a functional disturbance of the sweat-glands characterized by a sweat secretion of an offensive odor. The sweat production may be normal in quantity or more or less excessive, usually the latter. The condition may be local or general, commonly the former. It is closely allied to hyperidrosis, and may often be considered identical, the odor resulting from rapid decomposition of the sweat secretion. The decomposition and resulting odor have been thought due to the presence of bacteria.
What parts are most commonly affected in bromidrosis?
The feet and the axillæ.
What is the treatment of bromidrosis?
It is essentially the same as that of hyperidrosis (q. v.), consisting of applications of astringent lotions, dusting-powders, especially those containing boric acid and salicylic acid, and the continuous application of diachylon ointment. In obstinate cases weak formaldehyde solutions, Röntgen rays, and high-frequency currents can be tried.
Chromidrosis.
Describe chromidrosis.
This is a functional disorder of the sweat-glands characterized by a secretion variously colored, and usually increased in quantity. It is, as a rule, limited to a circumscribed area. The most common color is red. The condition is probably of neurotic origin and tends to recur. (True chromidrosis is extremely rare; most of the cases formerly thought to be such are now known to be examples of pseudochromidrosis.)
Treatment should be invigorating and tonic, with special reference toward the nervous system. The various methods of local electrization should also be resorted to.
Mild antiseptic and astringent lotions or dusting powders should also be advised.
Red chromidrosis or Pseudochromidrosis is a condition in which the coloring of the sweat occurs after its excretion and is due to the presence of chromatogenous bacteria which are found attached to the hairs of the part in agglutinated masses. The axilla is the favorite site. Treatment consists of frequent soap-and-water washings, and the application of boric acid, resorcin, and corrosive sublimate lotions.
Uridrosis.
Describe uridrosis.
Uridrosis is a rare condition in which the sweat secretion contains the elements of the urine, especially urea. In marked cases the salt may be noticeable upon the skin as a colorless or whitish crystalline deposit. In most instances it has been preceded or accompanied by partial or complete suppression of the renal functions.
Phosphoridrosis.
