If the tuberculous abscess has burst and left a sinus, this is apt to persist because of the presence of tuberculous tissue in its wall, and of superadded pyogenic infection, or because it serves as an avenue for the escape of discharge from a focus of tubercle in a bone or a lymph gland. [Illustration: FIG.
When it is about to burst externally, it may be difficult to distinguish a tuberculous abscess from one due to infection with pyogenic organisms. Even when the abscess is opened, the appearances of the pus may not supply the desired information, and it may be necessary to submit it to bacteriological examination.
They seldom prove dangerous to life except in diabetic subjects, but when they occur on the face there is a risk of lymphatic and of general pyogenic infection.
There is evidence that a mixed infection that is, the introduction of more than one species of organism, for example, the tubercle bacillus and a pyogenic staphylococcus increases the severity of the resulting disease.
This postulate applies to all kinds of pain, whatever their cause whether physical injury, pyogenic infection, the obstruction of hollow viscera, childbirth, etc. All forms of pain are associated with muscular action, and as in every other stimulation of the ceptors, each kind of pain is specific to the causative stimuli.
Subcutaneous rupture of the thoracic duct may result from a crush of the thorax. There are physical signs of fluid in one or other of these situations, but, as a rule, the nature of the lesion is only recognised when chyle is withdrawn by the exploring needle. #Lymphangitis.# Inflammation of peripheral lymph vessels usually results from some primary source of pyogenic infection in the skin.
Pain, however, is not the only symptom of the invasion of the body by pyogenic or parasitic organisms. Fever, invariably, and chills, often, accompany the course of the infections. Can these phenomena also be explained as adaptations of the motor mechanism for the good of the individual?
The first indication is to discover and deal with the source of infection, and in the indolent forms of lymphadenitis this will usually be followed by recovery. In the acute forms following on pyogenic infection, the best results are obtained from the hyperæmic treatment carried out by means of suction bells.
Those situated in the neck are most liable to suppurate, probably because of pyogenic organisms being brought to them by the lymphatics taking origin in the scalp, ear, or throat.
Delirium is a temporary disturbance of mind which occurs in the course of certain diseases, and sometimes after injuries or operations. It may be associated with any of the acute pyogenic infections; with erysipelas, especially when it affects the head or face; or with chronic infective diseases of the urinary organs.
