Other causes or associations of disease are: a compromised immune system, environmental toxins, radiation exposure, diet and other lifestyle choices, stress, and genetics. Diseases may also be multifactorial, requiring multiple factors to induce disease.
Stress ulceration is a single or multiple fundic mucosal ulcers that causes upper gastrointestinal bleeding, and develops during the severe physiologic stress of serious illness. It can also cause mucosal erosions and superficial hemorrhages in patients who are critically ill, or in those who are under extreme physiologic stress, causing blood ...
Routine medical tests revealed nothing unusual, and there were no signs of infectious disease as a cause. Ultimately it was decided that the events were caused by “stress due to upcoming exams” and the incident was determined to be an incident of “hysteria”. [47]
The work of the infectious diseases specialist therefore entails working with both patients and general practitioners, as well as laboratory scientists, immunologists, bacteriologists and other specialists. [115] An infectious disease team may be alerted when: [citation needed] The disease has not been definitively diagnosed after an initial workup
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
Vaccine-associated enhanced disease VCFS Velo cardio facial syndrome: vCJD variant Creutzfeldt–Jakob disease: VD Venereal disease: VHF Viral hemorrhagic fever: VHL Von Hippel–Lindau disease: VKC Vernal keratoconjunctivitis: VKH Vogt–Koyanagi–Harada disease: VOD veno-occlusive disease VP Variegate porphyria: VSD Ventricular septal defect ...
Epidemics of infectious disease are generally caused by several factors including a change in the ecology of the host population (e.g., increased stress or increase in the density of a vector species), a genetic change in the pathogen reservoir or the introduction of an emerging pathogen to a host population (by movement of pathogen or host).
Diagnostic modalities for infectious mononucleosis include: Person's age, with highest risk at 10 to 30 years. Medical history, such as close contact with other people with infectious mononucleosis; Physical examination, including palpation of any enlarged lymph nodes in the neck, or enlarged spleen.
