A consecutive series of 1530 patients with carcinoma of the breast has been reviewed to study the influence of age and marital status on the disease.

The risk of developing breast cancer increases with age, though a peak may be reached at 75 years. The risk of developing a tumour of advanced clinical stage at presentation apparently increases with age. Local recurrence rates and mortality rates are similar at all ages. It is concluded that the therapy required is similar in all age groups.

The increased risk of developing breast cancer in “never married” women is in the postmenopausal period. Survival rates and the distribution of the various presenting clinical stages are similar in both single and married patients.

Though ageing and marital status have an initiating effect on breast cancer, they do not have a continuing effect on the established disease.

A study of 384 consecutive femoral herniorrhaphies performed upon female patients admitted to Shouldice Hospital, Toronto, during a 19-year period was carried out. Its main purpose was to describe the techniques used and to evaluate the results obtained. A careful 10-year follow-up plan for all cases existed.

Two hundred and ninety-three operations were performed for the repair of simple femoral hernia; 91 were performed for the repair of femoral hernia which had developed following an initial ipsilateral inguinal or femoral repair performed previously, either in this hospital or elsewhere.

The basic repair was subinguinal. Four modifications are described, one entirely subinguinal and three combined with exploration of the inguinal canal.

The recurrence rate for simple femoral hernia in the female was 1.3% and for “recurrent” femoral hernia in the female, 5.5%.

A 20-year-old woman had a cyst of the proximal part of the common bile duct and a cyst of the left hepatic duct; these lesions were diagnosed preoperatively by intravenous cholangiography and successfully operated upon. At the time of writing, she has been followed up for one year.

Congenital defects in the biliary system are rare and, in a review of the literature, only two cases were found similar to this one. It is generally accepted that these lesions are congenital, but the exact pathogenesis is unknown.

Alonso-Lej, Rever and Pessagno2 reviewed the literature in 1959 and found 403 authentic congenital cysts of the hepatic ducts. The most common congenital defect is a single choledochal cyst of the lower end of the common bile duct. Pain, jaundice and tumour are the main symptoms.

Until the advent of intravenous cholangiography, these lesions were seldom recognized preoperatively. Means of operative repair as well as complications and prognosis are reviewed.
