This article reviews the virology, history, pathology, epidemiology, clinical presentations, complications, radiology, laboratory testing, diagnosis, treatment, and prevention of severe respiratory distress syndrome, with reference to documented outbreaks of the disease.
Fevers of unknown origin have been classified as classic, nosocomial, immune-deficient, and HIV-related. More than half of the 1407 human pathogens are zoonotic, making zoonotic infections an important subcategory in each of the classifications. This article describes both common and unusual zoonoses causing fevers of unknown origin. Simian immune virus is considered as a possible emerging infection. For special populations (the homeless, zoophiliacs, those whose occupation or leisure brings them in close contact with oceans or lakes, and veterinarians), zoonotic infection potentials are discussed.
Differentiating patients with allergic bronchopulmonary aspergillosis from those with asthma who have immediate cutaneous reactivity to Aspergillus fumigatus may be difficult. Both groups have IgE and IgG antibodies against aspergillus antigen. We describe methods for establishing IgE and IgG antibody indices using sera from asthmatic patients as a control serum pool. The IgE and IgG antibody indices are usually both positive and at least one index was positive in all patients during the acute stage. The indices had diagnostic value in individual patients during the other four stages, but were not consistently positive in patients in any other stage. In a patient with a suspected case, serodiagnosis should be attempted before corticosteroid therapy is started; thus, acute-phase serum should be obtained and stored before therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
