Transgastric biopsy of a submucosal gastric tumour.

Endoscopic biopsy is thought to be the best method to obtain biopsy samples of the gastrointestinal tract. In our case, however, an endoscopic forceps biopsy failed to confirm malignancy of an intramural gastric tumour. Since the tumour, about 4 cm in diameter, was well delineated on the CT scan, the patient was referred for a percutaneous CT-guided needle biopsy, which confirmed a gastrointestinal stromal tumour.

[Massive edema of the ovary].

Massive edema of the ovary is a rare condition found in young women as a result of partial or intermittent torsion of the ovary. Differentiation of this entity from tumors of the ovary is important to prevent overtreatment. Organ-preserving surgical treatment is indicated as the correct approach to management.

The use of a high-purity germanium detector for routine measurements of 125I in radiation workers.

A high-purity germanium detector was calibrated for the assessment of 125I uptake in the thyroid gland of radiation workers. A cylindrical water phantom (perspex walls) with high flexibility for position and size of the thyroid was constructed. Within a massive shielding chamber built for a whole-body counter, an activity of 2.

Intestinal worm burden and serum cholesterol or lipid concentration in a Shipibo population (Peru).

Paired samples of stool and serum of 32 members of the Shipibo tribe resident in the rain forest of the Peruvian lowlands were tested for worm egg count and serum lipid parameters, respectively. 90% of the stool samples tested were found to contain eggs or larvae of several worm species, most commonly 3 or 4 different species. Serum lipid levels were found to be relatively low, most probably due to a low proportion of dietary fat ranging from 16-31%.

[Radioactive cesium 137 and cesium 134 in follicle and seminal fluid].

Radioactive caesium nuclids were measured in follicular fluid and seminal plasma after the nuclear power station accident of Chernobyl. Immediately after the event (June - Aug. 86) both Cs 137 and Cs 134 were negative, with the exception of one sample.
