TL;DR: This is the first population-based epidemiological study of MG in Taiwan and the incidence rate and prevalence were higher than in most published studies, especially in old age groups.
Abstract: Background: The purpose of this study is to investigate the epidemiology and medical expenses of myasthenia gravis (MG) in Taiwan. Methods: Cases of MG were identified from the National Health Insurance Research Database with corresponding codes of the International Classification of Diseases, ninth revision (ICD-9), from January 2000 to December 2007. Age- and sex-specific incidences were estimated by dividing the incidence number by population data obtained from the Department of Statistics, Ministry of the Interior. Results: During the study period, 5,211 cases were identified. The incidence ratio of males to females was 0.68. The average annual incidence rate was 2.1/100,000. MG occurred in all age groups with a higher incidence in older individuals and the lowest incidence in the 10- to 14-year-olds for both sexes. Among the 5,211 cases, 615 (12%) had a neoplasm of the thymus. The prevalence increased steadily during the study period from 8.4/100,000 in 2000 to 14.0/ 100,000 in 2007. Conclusions: This is the first population-based epidemiological study of MG in Taiwan. The incidence rate and prevalence were higher than in most published studies, especially in old age groups.
TL;DR: The immunological cross-reaction between acetylcholine receptor and thymic components may explain the association between endplate and Thymus disorders in myasthenia gravis.
Abstract: A defined immunological cross-reaction was observed between acetylcholine receptor fraction from the electric eel, Electrophorus electricus, and two calf thymus fractions. The cross-reaction was demonstrated on the cellular level by means of the lymphocyte transformation technique, and on the humoral level, by means of the microcomplement fixation assay. In the human disease myasthenia gravis both acetylcholine receptor at the neuromuscular junction and the thymus are affected, probably by an autoimmune mechanism. The immunological cross-reaction between acetylcholine receptor and thymic components may explain the association between endplate and thymus disorders in myasthenia gravis.
TL;DR: The incidence of YFSAE has been associated with increasing age and thymus disorders, but still a number of cases with any risk factor remain unexplained, which suggests that other factors could be involved in the appearance of these postvaccinal adverse events.
Abstract: Background: Yellow fever, a mosquito-borne viral haemorrhagic fever, is one of the most lethal viral diseases. At present, an efficient vaccine for prevention is available, but may cause serious adverse events. Methods: The authors review the up-to-date knowledge for serious adverse events of the yellow fever vaccine (YFSAE): hypersensitivity reactions, neurotropic and viscerotropic syndromes. Results: The incidence of YFSAE has been associated with increasing age and thymus disorders, but still a number of cases with any risk factor remain unexplained, which suggests that other factors, from the virus or the host, could be involved in the appearance of these postvaccinal adverse events. Conclusions: YFSAE are uncommon but must be prevented. Further research on the virus–host immune response is needed to have a better understanding of the basis for the appearance of these severe side effects after vaccination. Vaccination should be limited to people with a true risk of exposure to wild-type yellow fever v...
