Protein concentrations in fluid from gross cystic disease of the breast.

Wide variations in the concentrations of IgA, IgG, lactoferrin, lysozyme and albumin were found in 96 cyst fluids obtained from 75 patients with gross cystic disease of the breast. Sedimentation coefficient determination were performed on 19 of the cyst fluids with the highest IgA concentrations in an attempt to discover the basis for the wide variation and two types of cyst fluids were found: cyst fluids that resembled external secretions such as colostrum of milk with the IgA wholly or predominantly in the 11S (secretory) form, and low concentrations of IgG and albumin, and cyst fluids that resembled serum with the IgA wholly or predominantly in the 7S (serum) form, and high concentrations of IgG and albumin. Some cyst fluids contained low concentrations of all proteins measured, and no relationship was observed between the concentrations of the proteins studied, and age, parity or menstrual status.

Androgen conjugates in human breast cyst fluids.

Dehydroepiandrosterone sulfate (DHAS) has been measured by radioimmunoassay in 100 breast cyst fluids obtained from 82 women. Values ranged from 1.5 to 1,155 microM with a median of 140 microM. These concentrations are in excess of those for plasma but are comparable or less than values for breast secretions obtained by nipple aspiration. Levels of DHAS in cyst fluid were not significantly affected by age, menopausal status, or parity of the subject or by the volume of cyst fluid obtained. In patients with multiple cysts, DHAS values from cysts aspirated from the same breast on the same data were relatively comparable, but wide variations were frequently observed between cysts aspirated on different occasions from the same breast and between cysts from different breasts of the same patient, whether sampled simultaneously or sequentially. Such variability must complicate comparative studies among women.

Diaphragmatic rupture due to blunt abdominal trauma.

Twenty-two instances of diaphragmatic rupture secondary to blunt thoracoabdominal trauma were seen at the Trauma Unit of the Health Sciences Centre, Winnipeg, Manitoba, Canada during a 30 year period. Diaphragmatic laceration occurred in the right leaf in 11, in the left in ten, and in both sides in one instance. In 14, the diagnosis was made and repair effected within 24 hours of presentation. Seven were diagnosed and treated from three days to several years after the injury. Two patients died soon after admission. They were victims of multiple intra-abdominal as well as intrathoracic injuries. Repair was generally effected through a laparotomy during the immediate post-traumatic period. Thoracotomy was used in those diagnosed after the latent interval. The diagnosis of diaphragmatic disruption should be considered in any patient suffering from blunt thoracoabdominal trauma. Usually a roentgenogram of the chest will confirm the suspected injury. In contradistinction to most of the reported series, our experience indicates that right diaphragmatic injuries are more common than what is usually thought.
