Polycyclic aromatic hydrocarbons in olive oils on the Italian market.
The six olive oils and seven virgin olive oils which are most consumed in Italy were analysed for 28 polycyclic aromatic hydrocarbons (PAHs). The aim was to evaluate whether a carcinogenic hazard for the general population can derive from the dietary intake of this food, which is consumed particularly highly in the Mediterranean area. The analytical method involved extraction by liquid-liquid partition, filtration on silica gel, clean-up by thin-layer chromatography on silica gel, and analysis by high-resolution gas chromatography with a flame ionization detector. The 3- and 4-ring PAHs which are most abundant in the environment were found in all samples, at individual levels up to ca. 40 micrograms/kg (for phenanthrene); no important difference was observed between olive oils and virgin olive oils. PAHs which are most suspected of being carcinogenic for humans were not detected (limit of detection, ca. 3 micrograms/kg). The average yearly intake of the detected PAHs through this food was estimated at ca. 0.56 mg per capita.

[Ovarian hyperstimulation syndrome with bilateral hydrothorax and ascites].
Ovarian hyperstimulation syndrome (OHSS) is an unusual complication of ovarian stimulation with exogenous gonadotrophins. We describe a case of severe OHSS with bilateral hydrothorax and ascites. We discuss the different pathogenetic hypothesis and the differential diagnostic possibility.

CCNU, vinblastine, procarbazine and prednisone (CVPP) with extended-field radiotherapy in the treatment of early unfavorable Hodgkin's disease. A prospective study on behalf of the Gruppo Italiano per lo Studio dei Linfomi (GISL).
PURPOSE: To test the adequacy of the CVPP four-drug regimen as ancillary chemotherapy associated with extended-field radiotherapy in the treatment of early, unfavorable, clinically staged Hodgkin's disease. PATIENTS AND METHODS: The population of this prospective, multicenter study consisted of 49 patients with stage I-II disease, associated with bulky involvement or unfavorable histology (lymphocyte-depleted nodular sclerosis or lymphocyte depletion), systemic symptoms or extranodal involvement, or presenting with stage III A favorable-histology disease, with or without extranodal involvement. RESULTS: Complete remission was achieved in 39 patients, partial remission in 2, while 8 patients did not respond. Four patients have relapsed so far (median follow-up: 43 months), all of whom were subsequently rescued with different salvage treatments. Dose intensity (mean +/- SD: 0.83 +/- 0.12) and hematological toxicity (including 2 deaths from infection) were higher when RT followed CT than when it was interposed in the middle of the 6 cycles. No growth factors were used. Nonhematological toxicity was very low and fully tolerable. CONCLUSIONS: Results confirmed the mild neurological and gastroenteric side effects of CVPP that make it an interesting MOPP-variant regimen. This combination seems most indicated when a regimen devoid of cardiac and pulmonary toxicity is required for association with full-dosage mediastinal radiotherapy, as is often the case in early, unfavorable Hodgkin's disease. The optimal sequence consists of radiotherapy administered after completion of the chemotherapy program. The use of growth factors for correction (or prevention) of marked leukopenia seems appropriate.
