Acute tonsillitis is a general acute infectious disease primarily affecting palatine tonsils. The inflammatory process may involve other areas of the lymphadenoid pharynx and larynx as well - the lingual, laryngeal and nasopharyngeal tonsils. The infection process can be exogenous (more often) or endogenic (autoinfection).
Neurangiosis is used to designate inherently functional but different in origin and symptoms vegetative disturbances caused by the impaired neurohumoral regulation of the vegetative function. This kind of disturbances usually occurs during neuroses, hypodynamia, endocrine disharmonies during pubertal and climacteric periods, as well as neurosis-like states caused by neuropsychic or physical overwork, infections, intoxications, abstinence (in case of toxicomania), etc.
