Tilbury Fox (" Skin-Diseases," 2d American edition, New York, 1873, p. 502) calls it a parenchymatous inflamma- tion of the hair-follicles, with the ordinary results of long-con- tinued congestion. He says it is an independent morbid state of the actual hair-follicle itself, the cause of which is doubt- ful, though external irritants, as shaving and long-continued exposure to heat-rays, can produce it in persons "out Purchase Geodon of health." Nelligan ("Diseases of the Skin," 4th American edition, Philadelphia, 1864, p. 275) considered all cases of sycosis as parasitic. Wilson (" Lectures on Dermatology," London, 1871, p. 136) says it Buy Geodon Online is an inflammation of the hair-follicles. There are sev- Cheap Geodon eral varieties of the Buy Geodon disease, and among them is observed the phytiform degeneration of tlie epithelium consequent on de- ranged development and nutrition of the tissue. Hutchinson (" London Hospital Reports," vol. iii., 1866, p. 389) denies the existence of a parasitic sycosis. McCall Anderson (" Eczema," 3d ed., London, 1814, cap. xii.) describes under the term eczema pilare facicei appear- ances which correspond exactly with those of sycosis; yet he says it differs from the latter in being simply an extension of the eczema to the perifollicular region, while sycosis con- sists in small abscesses and tubercles. Baudet (" Traite des Affections de la Peau," Paris, 1869, p. 94) says it is an inflammation of the hair-follicles depending on an arthritic constitution. He believes that a sycotic erup- tion, whether arthritic or parasitic, can be converted into a syphilitic or a scrofulous eruption if the patient, while afflected with sycosis, becomes syphilitic or scrofulous. The other French writers, as Cliauslt, Rayer, Duchenne, Dupare, Gibert, Rochard, Divergie, Giubout, etc., have con- tributed nothing worthy of special mention. Wertheim {Zeitschrift der h. h. G^sellschaft der Aerzte, 1861) made use of the microscope in studying this disease, but only with the object of confirming previously-conceived ideas of its nature and cause. He argued thus: Since a \ SYCOSIS. 127 hair is always in the centre of every pustule, and pus always follows the extraction of such a hair, therefore the hair-folli- cle must be the seat of the inflammation. Every such follicle will therefore inclose an abscess with its sheaths, and ever^'^ pustule is a metamorphosed hair-follicle. As sycosis appears but very rarely on other parts of the body than that of the bearded parts of the face, therefore the cause of the disease must be in the anatomical character of the hair-follicles of this region. Believing in those conjectures, he examined the structure of healthy hair-follicles taken from different parts of the body. From these studies he found that in the beard the hair has a greater diameter, in comparison with the diameter of its sheaths, than in any other part of the body. As the pus reaches the surface by destroying or pushing aside the exter- nal and internal root-sheaths, therefore, when the hair-follicle is inflamed, the pus has much more difiiculty in reaching the surface when the hair is thick and the sheaths thin, than when the hair is thin and its compressible sheaths thick. On account of the resistance which a thick hair offers to the immediate evacuation of pus, the latter collects, and an abscess is formed. Kobner (" Klinische und experimentelle Mittheilungen aus der Dermatologie und Syphilidalogie," Erlangen, 1864, p. 13) was the first to give any description of the changes which take place in the hair in sycosis. He names the dis- ease folliculitis barbae, and says it has no connection with acne, but is an idiopathic inflammation of the follicle, which inflammation is the cause of the nutrition changes which take place in the hair. This inflammation may be produced by changes of temperature as well as from chemical and mechan- ical irritants. lie examined hairs extracted in different stages of the eruption, but did not make any microscopical examination of the diseased follicles in situ or otherwise. The changes outside the follicle he regards as consecutive to those taking place within it. He says that first the external and then the internal root-sheaths swell, their cells become en- larged, increase in number, divide, and finally are partly transformed into pus and detritus. The hair itself is not changed at first, but later it loses its connection with the fol- licle, the bulbi swell two or three times their normal size, and 128 THE STRUMOUS ELEMEJ!fT IN THE become infiltrated with a sero-purulent fluid. According to Kobner, the primary changes therefore take place in the ex- ternal and internal root-slieaths. The cause of the perifol- licular inflammation, he finds, lies in the anatomical construc- tion of the part, in its richness in blood-vessels and nerves, and the deep situation of the follicles. Since the time of Bateman, therefore, the disease has been regarded by almost all writers as an inflammation of the hair- follicles, produced by irritating agents. Wertheim and Kob- ner were the only writers who studied the disease with the aid of the microscope, but they examined only hairs extracted from the part affected, and not the whole tissue affected ; i. e., they did not examine the affected part itself. In my own studies upon this subject I examined portions of skin taken from the living subject and affected with the eruption in its different stages, and have followed the process from its commencement to its termination, either in complete restitution of the parts, or in greater or less destruction of the skin of the affected region. {To he concluded^ with Illustrations, in next Number.)
