The minimal clinical reactivity reported in this trial confirms our previous experience with the vaccine. 13. The vaccine was shown to be highly immunogenic in healthy children between the ages of 1 and 14 years. Over 94 per cent of the vaccine recipients had detectable varicella antibody eight weeks after vaccination.
Peritoneal inclusion cysts occur almost exclusively in premenopausal women with active ovaries, pelvic adhesions, and impaired absorption of peritoneal fluid, which leads to formation of fluid-filled cysts that conform to the shape of the peritoneal cavity, and they may recur (1).
Signs and symptoms. The parasites form slowly enlarging fluid-filled cysts which may become very large. Cysts occur most commonly in the liver or lungs, but may occur in any organ, including the heart, brain and bones. Cysts often do not cause symptoms unless they become very large or break. Hydatid cysts are diagnosed by x-ray, ultrasound, CT or MRI scans and may sometimes be confirmed by a blood test.
