The Gothenburg Breast Screening Trial.

Background: Although there is evidence for a reduction in breast carcinoma mortality with mammographic screening, some doubts have been expressed, and there is still uncertainty regarding the age specific effects.

Methods: The authors report on a randomized, controlled trial of mammographic screening for breast carcinoma that was conducted among 51,611 women (21,650 women who were invited to a screening [the study group] and 29,961 women in a control group) ages 39-59 years in Gothenburg, Sweden. Among women in the study group, the screening interval was 18 months.

The Gothenburg breast screening trial: first results on mortality, incidence, and mode of detection for women ages 39-49 years at randomization.

Background: The effect of mammography screening on breast carcinoma mortality in women ages < 50 years remains unclear.

Methods: A randomized trial of invitation to breast carcinoma screening with mammography was performed in the city of Gothenburg, Sweden. The purpose was to estimate the effect of mammographic screening on breast carcinoma mortality in women ages < 50 years.

The Gothenburg Breast Cancer Screening Trial: preliminary results on breast cancer mortality for women aged 39-49.

We carried out a randomized trial of invitation to screening mammography in the city of Gothenburg, Sweden, to estimate the effect of screening on breast cancer mortality in women under age 50 years. A total of 11,724 women aged 39-49 were randomized to the study group, which was invited to mammographic screening every 18 months; 14,217 women in the same age range were randomized to a control group, which was not invited to screening until the fifth screen of the study group. Breast cancers diagnosed in both groups between randomization and immediately after the first screen of the control group were followed up for death from breast cancer to the end of December 1994.

Results of postoperative clinical examination of inguinal hernia after three years.

Of 285 consecutively operated inguinal hernias in 274 patients 87.4% were clinically examined after three years by two independent investigators. The operations were performed by several surgeons in a small community hospital.

Treatment of retained bile duct calculi with T-tube infusion of sodium cholate and heparin.

A series of 26 patients with retained radiolucent bile duct calculi diagnosed at postoperative cholangiagrophy through the T-tube is presented. All patients were treated with infusion of 15-20 g sodium cholate in 1000 ml saline and 20,000 units of heparin in 1000 ml saline per 24 hours. In 19 of 26 patients (73 per cent) the calculi disappeared.
