#What is malignant pustule?#

Malignant pustule is a furuncle- or carbuncle-like lesion resulting from inoculation of the virus generated in animals suffering from splenic fever, or "charbon," and is accompanied by constitutional symptoms of more or less gravity. A fatal termination is not unusual.

#What is the cause of pustula maligna?#

The disease is due to the presence of the bacillus anthracis.

#What is the treatment of malignant pustule?#

Early excision or destruction with caustic potash, with subsequent antiseptic dressings; and internally the free use of stimulants and tonics.

#Post-mortem Pustule.# (Synonym: Dissection Wound.)

#Describe post-mortem pustule.#

Post-mortem pustule develops at the point of inoculation, beginning as an itchy red spot, becoming vesico-pustular, and later pustular, with usually a broad inflammatory base, and accompanied with more or less pain and redness and not infrequently lymphangitis, erysipelatous swelling, and slight or severe sympathetic constitutional disturbance.

#What is the treatment of post-mortem pustule?#

Treatment consists in opening the pustule and thorough cauterization, and the subsequent use of antiseptic applications or dressings. Internally quinia and stimulants if indicated.

#Frambsia.# (Synonyms: Yaws; Pian.)

#Describe frambsia.#

Frambsia is an endemic, contagious disease met with in tropical countries, characterized by the appearance of variously-sized papules, tubercles, and tumors, which, when developed, resemble currants and small raspberries, and finally break down and ulcerate. It is accompanied by constitutional symptoms of variable severity.

Hygienic measures, good food, tonics, and antiseptic and stimulating applications are curative.

#Verruga Peruana.# (Synonyms: Peruvian Warts; Carrion's Disease; Oroya Fever.)

#Describe verruga peruana.#

A specific inoculable affection endemic in some valleys of the Western Andes, in Peru, and characterized by a prodromal febrile period and subsequent outbreak of peculiar pin-head- to pea-sized, or larger, bright reddish, rounded, wart-like elevations. The prodromal symptoms, of an irregular malarial or typhoid type, with associated rheumatic and muscular pains, may last for weeks or several months, usually abating when eruption presents. The lesions may be crowded together in great bunches. The face and limbs are favorite localities. The disease is inoculable and thought to be due to a bacillus.

The fatality varies between 10 and 20 per cent. Tonics and stimulants are prescribed.

#Equinia.# (Synonyms: Farcy; Glanders.)

#What is equinia, or glanders?#

A rare contagious specific disease of a malignant type, derived from the horse, and characterized by grave constitutional symptoms, inflammation of the nasal and respiratory passages, and a deep-seated papulo-pustular, or tubercular, nodular (farcy buds), ulcerative eruption. A fatal issue is not uncommon. It is due to a micro-organism.

Treatment, both local and constitutional, is based upon general principles.

#Miliaria.# (Synonyms: Prickly Heat; Heat Rash; Lichen Tropicus; Red Gum; Strophulus.)

#What do you understand by miliaria?#

An acute mildly inflammatory disorder of the sweat-glands, characterized by the appearance of minute, discrete but closely crowded papules, vesico-papules, and vesicles.

#Describe the symptoms of miliaria.#

The eruption, consisting of pin-point to millet-seed-sized papules, vesico-papules, vesicles, or a mixture of these lesions, discrete but usually numerous and closely crowded, appears suddenly, occurring upon a limited portion of the surface, or, as commonly observed, involving a greater part or the whole integument. The trunk is a favorite locality. The papular lesions are pinkish or reddish, and the vesicles whitish or yellowish, surrounded by inflammatory areola, thus giving the whole eruption a bright red appearance--miliaria rubra. Later, the areolæ fade, the transparent contents of the vesicles become somewhat opaque and yellowish-white, and the eruption has a whitish or yellowish cast--miliaria alba. In long-continued cases, especially in children, boils and cutaneous abscesses sometimes develop; and it may also develop into a true eczema.
