ABSTRACT
This is a retrospective study on 162 node-negative patients, with both biochemical and clinical factors being measured for determination of prognostic markers. Steroid receptors were measured on all tumors, while tumor size, histological grade, ploidy status, and cell cycle kinetics indicators could not be found or measured on 25 or less of the patient group. The primary focus of this study was the measurement of cathepsin D, analyzed by two different procedures, and 161 of the 162 patients had at least one value. The antigenic assay was performed using the US-CIS kit, and it was sensitive and reproducible. A biochemical assay using the enzymatic activity of cathepsin D was developed, and it gave proportional values, compared to the antigenic assay values (r2 = 0.79). Our results indicated that the mean antigenic levels were 20% higher than the biochemical assay levels (P = 0.001). High levels of cathepsin D by the antigenic assay predicted poor relapse-free (P = 0.0001) and overall (P = 0.0004) survival. High levels of cathepsin D by the biochemical assay also predicted poor relapse-free (P = 0.031) and overall (P = 0.0013) survival. The cathepsin D values were still useful as predictors of outcome after multivariate analysis. Several other factors, such as grade and S phase, were useful as additional prognostic indicators. In conclusion, cathepsin D is the most useful marker in node-negative patients, and the analysis can be performed by both a biochemical and an antigenic assay.

BACKGROUND: Despite rapid proliferation of descriptive studies of health care providers (HCPs) and protocols for identification and management of domestic violence (DV), few reliable instruments exist for assessing HCPs' attitudes, beliefs, and behaviors regarding this practice. This study describes the development and psychometric properties of a measure of attitudes, beliefs, and self-reported behaviors related to the identification and management of DV. METHODS: We used a multiphase study design to develop items across eight content domains. We administered an initial pool of 104 items to a pilot sample of 129 primary care providers (physicians, physician assistants, nurse practitioners, and medical assistants) in a large, urban health maintenance organization. Descriptive statistics, principal components, and reliability analyses were performed on each of the eight content domains. The analyses guided the deletion of items and development of additional items, yielding a 56-item pool. The items were then administered and re-analyzed with an independent sample of 246 HCPs. RESULTS: Six separate and reliable domains were identified: Perceived Self-Efficacy, System Support, Blame Victim, Professional Role Resistance/Fear of Offending Patient, Victim/Provider Safety, and Frequency of DV Inquiry. We found item domain Cronbach alpha to be acceptable, ranging from 0.73 to 0.91. The final overall measure had 39 items and an alpha of 0.88. Data are reviewed that support the measure's sensitivity to change in response to a training intervention. CONCLUSION: The measure provides a reliable method for assessing provider characteristics and training needs. It may also serve to evaluate training and policy interventions in DV.

BACKGROUND: Diagnosis of domestic violence (DV) in primary care is low compared to its prevalence. Care for patients is deficient. Over a 1-year period, we tested the effectiveness of an intensive intervention to improve asking about DV, case finding, and management in primary care. The intervention included skill training for providers, environmental orchestration (posters in clinical areas, DV questions on health questionnaires), and measurement and feedback. METHODS: We conducted a group-randomized controlled trial in five primary care clinics of a large health maintenance organization (HMO). Outcomes were assessed at baseline and follow-up by survey, medical record review, and qualitative means. RESULTS: Improved provider self-efficacy, decreased fear of offense and safety concerns, and increased perceived asking about DV were documented at 9 months, and also at 21 months (except for perceived asking) after intervention initiation. Documented asking about DV was increased by 14.3% with a 3.9-fold relative increase at 9 months in intervention clinics compared to controls. Case finding increased 1.3-fold (95%, confidence interval 0.67-2.7). CONCLUSIONS: The intervention improved documented asking about DV in practice up to 9 months later. This was mainly because of the routine use of health questionnaires containing DV questions at physical examination visits and the placement of DV posters in clinical areas. A small increase in case finding also resulted. System changes appear to be a cost-effective method to increase DV asking and identification.

Domestic violence as encountered in day-to-day practice is greatly underidentified. It is estimated that only 3% of cases are presently being identified, and practitioners are uncertain of what to do if a case is discovered. In this paper, a training program to improve identification and management of domestic violence (DV) in primary care and the providers' responses to the program are described. A multimodal training program was undertaken to demonstrate and practice the incorporation of didactic content into practice for the health care teams. Two medical centers from a large staff-model HMO were chosen at random from five volunteering for training. The entire adult health care medical center teams, including physicians, physician assistants, RNs, LPNs, medical assistants, and receptionists, were the recipients of the training. Assessment of provider valuation of the components of the training program was performed by administering a standardized 5-point Likert-scaled questionnaire 9 months after the training. This time interval was chosen because we were interested in lasting program effects. Core didactic content, such as the epidemiology of DV, identification and management of victims and batterers, and legal issues, was highly rated. Delivery of the content through role-playing, start-stop videos and presentations by former victims received lesser but solid support. Follow-up assessment 9 months post training demonstrates solid support for many components of the program: highest for specific information content areas, but strong for techniques and processes. The training program appears to be a promising method to improve provider skills in DV management.

OBJECTIVE: To explore primary care physicians' experiences with domestic violence victims to determine the barriers to problem recognition and intervention in the primary care setting. DESIGN: Ethnography, a qualitative research method involving the use of open-ended, semistructured interviews. SETTING: An urban health maintenance organization serving a predominantly white, middle-income population. PARTICIPANTS: Thirty-eight physicians, predominantly family practitioners (89%), were interviewed. RESULTS: Analysis of the interviews revealed that physicians found exploring domestic violence in the clinical setting analogous to "opening Pandora's box." Their issues include lack of comfort, fear of offending, powerlessness, loss of control, and time constraints. CONCLUSION: This study revealed several barriers that physicians perceived as preventing them from comfortably intervening with domestic violence victims. These issues need to be addressed in training programs. Further studies should be done to assess generalizability of these findings to other groups of physicians.

An 85-year-old woman had a 7-year history of recurrent uterine adenosarcoma. One year after curettage-related uterine perforation, she developed a pelvic mass that was attached to the uterine serosa and was histologically identical to her endometrial lesions. The pelvic neoplasm probably resulted from implantation of tumor through the myometrial tear and is the first reported example of serosal adenosarcoma following myometrial perforation. The definition of sarcomatous stroma in Müllerian adenosarcoma, and thus its separation from adenofibroma, has not been delineated. A review of the literature indicates, however, that lesions recurring after hysterectomy have greater than three mitotic figures per 10 high-power fields. Incompletely excised neoplasms, treated by dilation and curettage only, often regrow, regardless of mitotic rate. Adenosarcoma may have a deceptively bland low-power pattern and must be differentiated from adenofibroma and benign polyps.

OBJECTIVE: To assess the attitudes and beliefs of the primary care provider team (physicians, physician assistants, nurses, and medical assistants) toward the identification and management of abused patients and perpetrators of domestic violence (DV). DESIGN: Survey of the health care team using a confidential questionnaire. SETTING AND SUBJECTS: Five primary care clinics with 240 providers at a large urban health maintenance organization. RESULTS: The response rate was 86% (206 respondents). Fifty percent of clinicians and 70% of nurses/assistants believed that the prevalence of DV in their practice was 1% or loss; 1 in 10 clinicians and nearly half of nurses/assistants had never identified an abused person; 45% of clinicians never or seldom asked about DV when examining injured patients; and all participants were much less confident in asking about DV than about smoking or consuming alcohol. Twenty-five percent believed the abused person's personality led to the violence; 28% believed they did not have strategies to help abused persons; and 20% were concerned for their personal safety in discussing DV. Only 10% believed they had management information, but 77% had not attended any educational programs on DV in the past year. CONCLUSIONS: This study provides important information about current knowledge, attitudes, and beliefs of health care providers toward the diagnosis and management of DV. This information should prove useful to all who attempt to design clinical strategies and educational programs to address this issue.

Low concentrations of potassium and magnesium in serum have been implicated in cardiac arrhythmias; the importance of mild hypokalemia or hypomagnesemia is uncertain. To investigate possible associations among use of diuretics, the concentration of these ions in serum, and the onset of clinically important arrhythmias, we reviewed records of 103 patients admitted to our Coronary Care Unit during three months and found mild to moderate hypokalemia and hypo- magnesemia in 18 and 24%, respectively. The significant correlation between the concentrations of magnesium and potassium in serum at admission (r = 0.27, p less than 0.007) remained constant in patients, whether they were receiving diuretics or not. Potassium concentrations were significantly lower (p less than 0.05) in patients receiving diuretics (3.93 mmol/L) than in those who were not (4.21 mmol/L), but the mean concentrations of magnesium did not differ significantly. Except for myocardial infarction, no single variable or combination of variables was highly predictive of cardiac arrhythmias in these patients. We conclude that there is no strong predictive relationship between mildly decreased concentrations of magnesium or potassium in serum and onset of cardiac arrhythmias.

In 1993, an outbreak of 10 cases of Bartonella quintana bacteremia occurred among homeless, alcoholic, human immunodeficiency virus (HIV)-negative persons in Seattle. To estimate the prevalence of past exposure B. quintana among this population, a serosurvey was conducted in 1994 among patients at a downtown Seattle clinic. Microimmunofluorescent titers to B. quintana in 192 clinic patients were compared with titers in 199 age- and sex-matched Seattle volunteer blood donors. Titers > or = 64 were detected in 20% (39/192) of clinic patients compared with 2% (4/199) of blood donors (P<.001). Among clinic patients, alcohol abuse was independently associated in multivariate analysis with titers > or = 64 (odds ratio, 3.3; 95% confidence interval, 1.6-6.9). Of the 39 patients with B. quintana titers > or = 64, 24 (62%) also had titers > or = 64 to Bartonella henselae, indicating serologic cross-reactivity between Bartonella species. These results suggest that a substantial proportion of this indigent, inner-city Seattle population was infected with B. quintana.
