Cryptosporidium case study and clinical outcomes
This work in writing is a case study of Cryptosporidium. Cryptosporidium is reported as a "coccidian protozoan parasite" and one that has received a great deal of attention over the past two decades as a "clinically important human pathogen." (Hannahs, nd, p.1) The discovery of Cryptosporidium is reported as associated with E.E. Tyzzer who described a "cell-associated organism in the gastric mucosa of mice" in 1907 as reported in the work of Keusch et al (1995). (Hannahs, nd, p.1) Cryptosporidium was believed for several decades to be a "rare, opportunistic animal pathogen". (Hannahs, nd, p.1)
The first case of human cryptosporidiosis occurred in a three-year-old girl in rural Tennessee in 1976 suffering from severe gastroenteritis for two weeks and reported in the work of Flanigan and Soave (1993). Cryptosporidium parvum was discovered through use of an electronic microscopic examination of the intestinal mucosa. Cryptosporidium parvus was associated with AIDS cases in the 1980s and this resulted in renewed attention of this infection as a "ubiquitous human pathogen." (Hannahs, nd, p.1)
Marfan syndrome: characteristics, diagnosis, and clinical management
Marfan syndrome was first described at the end of the 19th century, by Dr. Antoine Marfan in Paris. Since that time our understanding of the causes of this disorder has advanced considerably, yet detection and diagnosis still relies on the presence of a family history, a physical examination, and a few non-invasive laboratory tests. Despite the genetic underpinnings of this disorder, the development of a useful diagnostic genetic test remains lacking. Undiagnosed patients therefore run the risk of dying at an early age for lack of proper medical care. However, with treatment persons with Marfan syndrome can often live a long and fruitful life.
