Objective To examine the influence of operator specialty, volume of work and referral to an oncologist Design Population-based retrospective cohort study, using hospital records and Cancer Registry data.Setting The North Western Region, UK.Population Six hundred and ninety-one women undergoing laparotomy for histologically confirmed Methods Univariate and multivariate survival analyses.Main outcome measures Univariate survival estimates. Relative risks, derived from Cox's proportional hazards model, describing the effect on survival of surgeons vs gynaecologists as baseline, high volume vs low volume operators and referral vs nonreferral to an oncologist.Results After adjusting for woman and disease-related prognostic factors, operation by a surgeon was shown to have an adverse impact on survival (RR = 1.58,95% CI 1.19 to 2.10). Regardless of how a high volume operator was defined (in terms of the number of laparotomies performed), no survival advantage over low volume operators could be demonstrated. Women referred to an oncologist had significantly better survival than women not referred (RR = 0.54,95% CI 0-43 to 0.68)Conclusions All women undergoing surgery for ovarian cancer should have access to a gynaecological opinion and postoperatively should be referred for a nonsurgical oncological opinion.on the survival of women with ovarian cancer.ovarian malignancy during 1991 to 1992.

Deals with a study of the mineralogical and organic components of the monthly dust-fall deposited over Al Ain city, some 150km east of Abu Dhabi and 130km southeast of Dubai. The identification of the mineralogical and organic composition was carried out by means of infrared spectroscopy. This study reveals that the principal constituents of dust-fall over the studied city are calcite, gypsum, kaolinite, quartz, hematite, alkanes and phosphines. The sources of these constituents are attributed to local controls, both natural and man-induced.
