Mesenteric fibromatosis masquerading as an ovarian neoplasm twenty years after Chernobyl radiation exposure.

BACKGROUND: Since their initial description in 1832, desmoid tumors have been reported to occur in virtually every part of the body. Intra-abdominal desmoid tumors, or mesenteric fibromatosis, are often associated with Familial Adenomatous Polyposis mutation in a syndrome known as Gardner's Syndrome. Although sporadic cases of desmoid tumors do occur, unlike Gardner's Syndrome, they predominantly occur extra-abdominally. CASE: Case report of a 61-year-old female who presented with two months of abdominal pain, progressive lower abdominal distension and a 10-15 pound weight gain accompanied by one week of urinary hesitancy and frequency. Patient underwent a diagnostic workup for an ovarian neoplasm, but was found at surgery to have mesentric fibromatosis. CONCLUSION: Although uncommon, mesentric fibromatosis must be considered in the differential diagnosis when evaluating a patient with an abdominal mass of unknown origin.

Long-term decline of radiocesium concentration in seafood from the Ligurian sea (northern Italy) after Chernobyl.

The activity of 137Cs, 134Cs and 40K in tissues from fish, molluse and shellfish of the Ligurian sea was measured during 1987-1988. The mean annual concentrations in 1987 were 5.92 +/- 4.1 Bq/kg (wet tissue) for 137Cs and 2.7 +/- 1.5 Bq/kg for 134Cs and 2.46 +/- 1.82 and 0.33 +/- 0.57 Bq/kg respectively in 1988. The mean value of 40K activity was 138.6 +/- 22.1 Bq/kg. Contamination was significantly higher in the littoral area up to 1000 m from the coast (8.39 +/- 7.6 and 1.74 +/- 2.08 Bq/kg respectively versus 2.91 +/- 1.87 and 0.58 +/- 0.59 Bq/kg respectively in the open sea). The common octopus (Octopus vulgaris) had the highest radioactivity values and could be utilized as an indicator of radioactivity pollution. There were no significant differences regarding the trophic level, the seafood phylum, or the east and west Ligurian sea areas. Long-term reduction in the sea habitat was estimated at about 200 days for 137Cs and 110 days for 134Cs, reflecting differences in the physical half-life of these radionuclides. These values were lower than those found in terrestrial foodstuff and could have reflected dilution of the contaminants in the open sea. The effective dose equivalent for the Ligurian population of radiocesium originating from seafood was estimated at 1.3 microSv in 1987 and 0.5 microSv in 1988. These va ues represent 0.8 and 0.3% respectively of the annual dose (180 microSv/year) due to 40K intake with the diet.
