Trichinella Nelsoni


Presentation

  • Presented by scientists from 17 countries throughout the world, the papers are the record of the Sixth International Conference on Trichinellosis held at Val Morin, Quebec Province, Canada, July 8–12, 1984.[books.google.es]
Weakness
  • Myalgia was observed in 88 per cent, muscle weakness in 60 per cent, myositis in 62 per cent and arthralgia in 20 per cent of the patients. The arthralgia score was strictly related to myalgias-myositis.[ncbi.nlm.nih.gov]
Veterinarian
  • Therefore, the book is useful for parasitologists, immunologists, pathologists, clinicians, veterinarians and public health workers interested in Trichinella and trichinellosis.[books.google.es]
Pathologist

Fever
  • Phase II: muscular (parental) phase Onset 2 to 3 weeks after ingestion Fever Myalgias Edema Major systems affected: Gastrointestinal Musculoskeletal Other systems affected: Renal Proteinuria 85% Mortality up to 26% ( 2 )[ C ] Neurologic Paralysis Encephalitis[unboundmedicine.com]
Asymptomatic
  • Phase I: intestinal (enteral) phase Onset usually 48 to 72 hours after ingestion May be asymptomatic Gastroenteritis Larvae are released and mature in small intestines.[unboundmedicine.com]
Heart Failure
  • failure Myocarditis Mortality 23% ( 5 )[ C ] Hepatic: less common Hepatomegaly 34% Hypoalbuminemia 41% Hypoproteinemia 34% Fatty degeneration of liver 59% ( 6 )[ C ] Synonyms: trichinelliasis; trichinosis Pregnancy Considerations Transplacental passage[unboundmedicine.com]
Hepatomegaly
  • […] systems affected: Renal Proteinuria 85% Mortality up to 26% ( 2 )[ C ] Neurologic Paralysis Encephalitis Mortality up to 17% ( 3 , 4 )[ C ] Cardiovascular ECG abnormalities 81% Heart failure Myocarditis Mortality 23% ( 5 )[ C ] Hepatic: less common Hepatomegaly[unboundmedicine.com]
Myalgia
  • Myalgia was observed in 88 per cent, muscle weakness in 60 per cent, myositis in 62 per cent and arthralgia in 20 per cent of the patients. The arthralgia score was strictly related to myalgias-myositis.[ncbi.nlm.nih.gov]

Suggestibility
  • The biochemical results suggest the presence of genetic heterogeneity in T. nelsoni and support the existence of a zoogeographical segregation of the two gene pools.[ncbi.nlm.nih.gov]
  • The numbers of lions and spotted hyenas examined, with a prevalence of 12% and 23%, respectively, suggest that these species may be reservoirs of T. nelsoni in the area under study.[ncbi.nlm.nih.gov]
  • Higher incidence in Alaska and Northeastern United States Autopsy studies suggest that most mild cases are probably undiagnosed.[unboundmedicine.com]

Workup

Trichinella Spiralis
  • Infections with the parasite Trichinella spiralis have undoubtedly been present for thousands of years, but it was only 150 years ago that the parasite was associated with clinical disease in man and subsequently with the consumption of raw or inadequately[books.google.es]

Treatment

  • Clinical aspects, diagnosis and treatment of trichinellosis. Expert Review of Anti-infective Therapy. 2003, Vol. 1, No. 3, Pages 471-482 . Pozio E, Owen IL, Marucci G, La Rosa G. 2005.[web.stanford.edu]

Prognosis

  • T. nelsoni-related infection appears to induce musculoskeletal symptoms in the majority of patients, but the long term course and prognosis is favourable.[ncbi.nlm.nih.gov]

Etiology

  • Predominant age: 20 to 49 years, although cases were reported from all age groups Predominant sex: male female Etiology and Pathophysiology Eating undercooked meat contaminated with viable Trichinella cysts.[unboundmedicine.com]

Epidemiology

  • The program consisted of three symposia, each devoted to immunology, genetics, and epidemiology and control.[books.google.es]
  • 1987 1987 [Epidemiology of trichinosis in Italy: correlation between the wild cycle and man].[semanticscholar.org]
  • Epidemiology Incidence Only 15 cases were reported in the United States in 2011 ( 7 )[ C ] and 12 cases in 2012 ( 1 ). Worldwide from 1986 to 2009, there were 65,000 cases and 42 deaths ( 8 )[ C ].[unboundmedicine.com]

Pathophysiology

Prevention

  • Prolonged freezing may help prevent disease (less so for wild game meat). -- To view the remaining sections of this topic, please sign in or purchase a subscription -- Citation Stephens, Mark B., et al., editors.[unboundmedicine.com]
