ABSTRACT
The withdrawal of DuPont as a supplier of key raw materials created a major dislocation in the medical device industry. We studied the present and future impact caused by the market removal of polyethylene terephthalate (PET) yarn ("Dacron"), polytetrafluorethylene (PTFE) fiber and resin ("Teflon"), and polyacetal resin ("Delrin"). Findings were: 1) Dollar values of the permanent medical implant markets for PET yarn, PTFE fiber and resin, and polyacetal resin are a minute fraction, of their values for their other commercial markets; 2) The implant market value is clearly not commensurate with the liability risk; and 3) The majority of these materials consumed by this market are used in the production of lifesaving, permanent medical implants [e.g., vital blood vessel replacements made from knitted polyester (PET)]. The remainder is used in life-enhancing, permanent implants [e.g., hernia patches made of polyester (PET) fabric].

The DSM-III definition of borderline personality disorder emphasizes affective symptoms. The authors hypothesized that depressed patients with borderline personality disorder would be more likely to be suicidal than those without this diagnosis. Of 53 inpatients treated for depression, 46 manifested personality disorders; borderline personality disorder was the most prevalent axis II diagnosis. That borderline patients had more complicated courses than the other depressed patients was evidenced by their histories of suicidal behavior. Most patients diagnosed as having borderline personality disorder continued to fulfill criteria for this diagnosis even when suicide attempts were excluded as a diagnostic criterion.

Of 45 female inpatients with schizophrenia, depression, borderline personality, or depression and borderline personality, 28 met criteria for probable or definite premenstrual affective syndrome. Of these 28, 16 had abnormal sexual histories, compared with only 1 of the 17 women who did not have premenstrual affective syndrome. Of the 12 patients with both depression and borderline personality disorder, 9 had both premenstrual affective syndrome and abnormal sexual histories. The 6 patients who had been raped all met the criteria for premenstrual affective syndrome. The authors suggest that premenstrual affective syndrome may signify unresolved sexual conflicts in subgroups of psychiatric patients.
