It and other fatty acids maintain cell structure and are key determinants of membrane functions such as activation of receptor sites and enzyme binding. It has been postulated to have a prophylactic role in treating various chronic dis- ease states. Essential fatty acids are incorporated into cell membranes where they play a vital role in the structure of cell membranes, influencing membrane flexibil- ity, fluidity, and the behavior of membrane-bound proteins. This is available from at least one clinical trial with respect to dia- betic neuropathy, mastalgia, rheumatoid arthritis, and migraine.

Polyunsaturated fatty acids—administered for 6 months in an open-label, uncontrolled study—reduced the severity, frequency, and duration of migraine attacks in 86% of participants.

Reservoir- Human Mode of transmission- Infective (filariform) larvae penetrate the skin and enter the venous circulation purchase vytorin from india cholesterol test iphone. Incubation period- 2-4 weeks (from skin penetration up to when rhabditi form larvae appear in the feces) order vytorin with american express cholesterol ratio vs level. Period of communicability- As long as living worms remain in the intestine; up to 35 years in cases of auto-infection cheap vytorin amex cholesterol lowering foods urdu. Rhabditiform larvae: - Passed in feces cheap 800mg viagra vigour free shipping, or - Become filariform larvae in intestine buy online kamagra chewable, causing atutoinfection. Reservoir- Humans 53 Communicable Disease Control Mode of transmission- Through skin penetration by the infective larvae. Incubation period- Symptoms may develop after a few weeks to many months depending on intensity of infection and iron intake of the host. Period of communicability- Infected people can contaminate the soil for several years in the absence of treatment. Larval migration of the skin Produces transient, localized maculopapular rash associated with itching called ground itch. Blood sucking Light infection-no symptoms Heavy infection-result in symptoms of peptic ulcer disease like epigastric pain and tenderness. Further loss of blood leads to anemia manifested by exertional dyspenea, weakness and light-headedness. Reservoir – humans, especially children Mode of transmission- Primarily person-to-person, spread principally through the fecal-oral route. In rare instances, milk, 56 Communicable Disease Control food stuffs and other materials contaminated with feces have been incriminated as vehicles. Incubation period- commonly 7-14 days Period of communicability – not precisely known, but transmission is possible as long as the virus is excreted. Susceptibility and resistance- Susceptibility is common in children but paralysis rarely occurs. Clinical manifestation Usually asymptomatic or non-specific fever is manifested in 90% of cases. Diagnosis Based on clinical and epidemiological grounds 57 Communicable Disease Control Treatment Symptomatic Prevention and control 1. Infectious agent Echinococcus granulosus, a small tapeworm of dog Epidemiology Occurrence – occurs on all continents except Antarctica. Especially common in grazing countries where dogs consume viscera containing cysts. Reservoir- Domestic dogs and other canids are definitive hosts; they may harbor thousands of adult tapeworms in their 58 Communicable Disease Control intestines without signs of infection. Mode of transmission – directly with hand to mouth transfer of eggs after association with infected dogs or indirectly through contaminated food, water, soil or fomites.
