Bacterial varieties of gangrene. Pathology clinical varieties Acute infective gangrene; Malignant œdema; Acute emphysematous or gas gangrene; Cancrum oris, etc. Bed-sores: Acute; chronic. Gangrene or mortification is the process by which a portion of tissue dies en masse, as distinguished from the molecular or cellular death which constitutes ulceration. The dead portion is known as a slough.
Systemic treatment and cooking of all food had cleaned up the infective cercaria and individual infections, and after six months of intensive search, quarantine, and investigation, Kennon was morally certain that the disease had been eradicated. The last four reports confirmed his belief. He sighed as he leaned back in his chair. Blalok was at last convinced that his ideas were right.
The habitual use of gloves has also been adopted by the great majority of surgeons; the minority, who find they are handicapped by wearing gloves as a routine measure, are obliged to do so when operating in infective cases or dressing infected wounds, and in making rectal and vaginal examinations.
A large number of children, in convalescence from infective disorders, when the nutrition of the body has fallen to a low ebb, show as evidence of cerebral exhaustion a group of symptoms which in a sense are the reverse of those which characterise cerebral irritation and chorea. The healthy child is a creature of free movement.
On the other hand, if it is not directly involved but is merely influenced by the proximity of an infective focus, its bone-forming functions may be stimulated by the diluted toxins and the growth of the bone in length exaggerated. In paralysed limbs the growth from the epiphyses is usually little short of the normal.
On account of its power of neutralising toxins, iodoform is useful in these cases, and is best employed by packing the wound with iodoform gauze, and treating it by the open method, if this is possible. The general treatment is carried out on the same lines as for other infective conditions. #Chronic sapræmia or Hectic Fever.# Hectic fever differs from acute sapræmia merely in degree.
A century and a half ago, before the true character of infective disease was understood, it was observed that an individual who was attacked by the smallpox and recovered became incapable of receiving the infection again. He was "protected" or "immune." The practice of "inoculation" was introduced from the East by Lady Montague.
If it is decided to wait for separation of the dead bone, drainage should be improved, and the infective element combated by the induction of hyperæmia.
Every wound and sore, when antiseptic precautions are not used, becomes a most active and dangerous focus, and every patient suffering from an infective disease is probably a focus for the production of infective particles. When we consider, also, that hospital wards are occupied day and night, and continuously for weeks, it is not to be wondered at that microbes are abundant therein.
From the study of the processes by which immunity is secured against the effects of bacterial action the serum and vaccine methods of treating certain infective diseases have been evolved. The serum treatment is designed to furnish the patient with a sufficiency of antibodies to neutralise the infection.
