Using pictures to evoke spiritual feelings in breast cancer patients: development of a new paradigm for neuroimaging studies.

This study was designed to develop and validate a method for enhancing spiritual feelings, particularly in women who have received a diagnosis of breast cancer. The protocol specifically was developed to be used in functional magnetic resonance imaging (fMRI) studies. Eighteen breast cancer survivors rated pictures for their ability to enhance feelings of spirituality, happiness, and sadness. Results indicate that presenting carefully selected pictures with spiritual content (e.g., nature scenes, people engaged in contemplative behaviors) can effectively enhance spiritual feelings among breast cancer survivors. Future fMRI studies will explore the use of the protocol developed in this study for investigating neural activity during spiritual feelings and states.

Maternal levels of dichlorodiphenyl-dichloroethylene (DDE) may increase weight and body mass index in adult female offspring.

OBJECTIVES: To investigate the effect of prenatal exposure to polychlorinated biphenyls (PCBs) and dichlorodiphenyl-dichloroethylene (DDE) on weight, height and body mass index (BMI) in adult female offspring of the Michigan fisheater cohort examined between 1973 and 1991. METHODS: 259 mothers from the Michigan fisheater cohort were studied. Prenatal exposure to PCBs and DDE was estimated by extrapolating maternal measurements to the time that the women gave birth. 213 daughters aged 20-50 years in 2000 were identified and 83% of them participated in at least one of two repeated investigations in 2001/02 (n = 151) and 2006/07 (n = 129). To assess the effect of prenatal PCB and DDE exposure on anthropometric measurements, generalised estimating equations nested for repeated measurements (2001/02 and 2006/07) and for sharing the same mother were used. We controlled for maternal height and BMI and for daughters' age, birth weight, having been breastfed and number of pregnancies. RESULTS: Maternal height and BMI were significant predictors of the daughters' height, weight and BMI. Low birth weight (<2500 g) was significantly associated with reduced adult offspring weight and BMI. The weight and BMI of adult offspring were statistically significantly associated with the extrapolated prenatal DDE levels of their mothers. Controlling for confounders and compared to maternal DDE levels of <1.503 microg/l, offspring BMI was increased by 1.65 when prenatal DDE levels were 1.503-2.9 microg/l and by 2.88 if levels were >2.9 microg/l. Prenatal PCB levels showed no effect. CONCLUSION: Prenatal exposure to the oestrogenic endocrine-disrupting chemical DDE may contribute to the obesity epidemic in women.

Hormone replacement therapy with estrogen or estrogen plus medroxyprogesterone acetate is associated with increased epithelial proliferation in the normal postmenopausal breast.

The relative effects of postmenopausal hormone replacement therapy (HRT) with estrogen alone vs. estrogen+progestin on breast cell proliferation and on breast cancer risk are controversial. A cross-sectional observational study was carried out to examine the proliferative effects of HRT with estrogen or estrogen plus the progestin, medroxyprogesterone acetate, in breast tissue of postmenopausal women. Benign breast biopsies from 86 postmenopausal women were analyzed with antiproliferating cell nuclear antigen (anti-PCNA) and Ki67 antibodies to measure relative levels of cell proliferation. Epithelial density and estrogen and progesterone receptor status were also determined. The women were categorized either as users of: 1) estrogen (E) alone; 2) estrogen+medroxyprogesterone acetate (E+P); or 3) no HRT. Compared with no HRT, the breast epithelium of women who had received either E+P or E alone had significantly higher PCNA proliferation indices, and treatment with E+P had a significantly higher index (PCNA and Ki67) than treatment with E alone. Breast epithelial density was significantly greater in postmenopausal women treated with E and E+P, compared with no HRT. Thus, the present study shows that postmenopausal HRT with E+P was associated with greater breast epithelial cell proliferation and breast epithelial cell density than E alone or no HRT. Furthermore, with E+P, breast proliferation was localized to the terminal duct-lobular unit of the breast, which is the site of development of most breast cancers. Further studies are needed to assess the possible association between the mitogenic activity of progestins and breast cancer risk.

DNA flow cytometry does not predict 5- or 10-year recurrence rates for T1-2 node-negative breast cancer.

BACKGROUND: A small proportion of T1 or T2 node-negative breast cancer tumors will recur in patients by 5 years, and more by 10 years. Results of recent studies have suggested improvement in overall survival with administration of adjuvant chemotherapy to all patients. More sensitive and specific methods are needed to identify patients at highest risk for recurrence who might benefit most from adjuvant therapy, saving others from unnecessary treatment. Some investigators have suggested DNA flow cytometry as a method to discriminate patients at greatest risk for recurrence. HYPOTHESIS: DNA flow cytometry has predictive value for breast cancer recurrence in node-negative patients. METHODS: The cancer registry of a medium-sized university-affiliated hospital was used to identify patients with T1-2 N0 M0 breast cancer treated with a uniform surgical approach and no adjuvant therapy who had completed at least 5 years of follow-up or had recurrence. Flow cytometric analysis was performed on paraffin-embedded specimens. RESULTS: Of 115 patients, 92 (80%) had disease-free survival without recurrence and 23 (20%) had recurrence. Comparison of diploid and nondiploid tumors for likelihood of recurrence revealed no association (P = .79). Furthermore, the DNA index and S-phase fraction were not significantly different between recurrent and nonrecurrent groups. CONCLUSIONS: The likelihood of recurrence of small node-negative breast cancers after mastectomy cannot be accurately predicted on the basis of DNA flow cytometric analysis. Traditional methods for determining risks-such as nuclear and histological grade, lymph node status, and tumor size-seem to be more useful. Sentinel lymph node biopsy techniques may increase the detection of micrometastases.

The influence of cancer patients' symptoms and functional states on patients' depression and family caregivers' reaction and depression.

In this article the paths among cancer patients' physical and mental health and the reactions and mental health of their family caregivers were examined. Data for these analyses came from a cross-sectional sample of cancer patients who were recruited through ambulatory outpatient chemotherapy units, and their family caregivers. Patients' depression was explained largely by their symptomatology and, to a lesser extent, by loss of mobility. Patients' physical limitations impacted caregivers' daily schedules but not their physical health. Patients' levels of depression were related to those of their caregivers. However, caregivers' optimism proved to be a significant predictor of their mental health and reactions to caregiving.

A national breast cancer database.

The medical audit of technical and interpretive aspects of mammography has been recommended by a number of expert panels and as part of some regulations that govern the oversight of mammography. The value of the medical audit is to aid practitioners in the performance evaluation of mammography in their facilities. Collection and analysis of audit data at a regional or national level have the potential to allow for the comparison of practice-level performance with regional and national-level performance and to provide a public health tool for the evaluation and improvement of breast cancer detection. In addition, a regional and national-level breast cancer database has the potential for allowing monitoring and tracking of women participating in a screening program. Prior to establishing such a database, data must be protected from discovery and disclosure, and patient and physician confidentiality must be ensured.

A pilot study of the relationship between experts' ratings and scores generated by the NBME's Computer-Based Examination System.

This pilot study evaluates the consistency of experts' ratings of students' performances on the National Board of Medical Examiners' Computer Based Examination (CBX) cases and the relationship of those ratings to the CBX's scoring algorithm. The authors were investigating whether an automated scoring algorithm can adequately assess an examinee's management of a computer-simulated patient. In 1989-90, at the Michigan State University College of Human Medicine, eight students, completing a surgery clerkship, each managed eight CBX cases and took a computer-administered, multiple-choice examination. Six clerkship coordinators rated the students' performances in terms of overall management, efficiency, and dangerous actions. The ratings correlated highly with scores produced by the CBX's scoring system.

Emergency subxiphoid pericardial decompression for malignant pericardial effusion.

Malignant pericardial effusion can result in acute cardiac tamponade with serious hemodynamic compromise. This condition requires prompt pericardial decompression for relief of symptoms; however, the risks of general anesthesia in this setting are considerable. In a series of 12 patients, all operated on under local anesthesia without operative mortality, there were six patients with malignant pericardial effusion secondary to lung carcinoma; four patients, secondary to breast carcinoma; one patient, secondary to squamous cell carcinoma of the oral cavity; and one patient, secondary to an unknown primary. The clinical presentation of each was abrupt and echocardiography was definitive. The procedure is performed through an upper abdominal midline incision. The xiphoid process is excised, the diaphragm is visualized, and a pericardial window is created through which two chest tubes are placed through separate stab incisions. The tubes are removed when the drainage has subsided, usually 3-7 days. No medication or irritant is instilled. There was no recurrence following this treatment. The average survival time was 27 weeks with a range of 2-153 weeks. This operation should be part of the repertoire of the general surgeon who treats breast cancer and of the thoracic surgeon who treats lung cancer.

Benign lesions of the breast other than fibrocystic change.

Benign diseases of the breast other than those labeled as "fibrocystic" in nature can be divided into congenital, developmental, inflammatory, neoplastic, and miscellaneous categories. Several of the most common breast lesions in these categories are discussed in this article.

The timely diagnosis of breast cancer. Principles of risk management for primary care providers and surgeons.

Alleged delay in the diagnosis of breast cancer is one of the most common reasons for medical malpractice claims in the United States, accounting for the largest indemnity payments of any single medical condition. Although the diagnosis of breast cancer can be challenging and sometimes difficult, principles of management exist to assist health providers in pursuing a resolution of any breast complaint. Studies have shown that when litigation is pursued for alleged failure to diagnose breast cancer, multiple specialists are named in the suit. In most cases, patients filing claims of alleged failure to diagnose breast cancer are premenopausal, while the majority of women diagnosed with breast cancer are postmenopausal. This reflects, in part, the challenge of diagnosing the disease in women who have difficult clinical exams to interpret, as well as dense parenchyma on mammograms, which decreases the sensitivity of the radiograph interpretation. Principles of risk management to avoid a delay in diagnosis include (1) pursuing every breast complaint to resolution, (2) following breast cancer screening guidelines, (3) establishing an office tracking system for breast cancer screening reminders, (4) tracking results of all mammograms and follow-up studies ordered, (5) referring premenopausal women for the evaluation of any breast mass that persists through a menstrual cycle, (6) considering any asymmetrical breast finding as a cause for concern, (7) referring every woman with a breast finding on physical examination for consultation, regardless of the mammogram report, and (8) carefully documenting patient history, physical exam findings, clinical impression, and follow-up plans.

Breast carcinoma etiology: current knowledge and new insights into the effects of reproductive and hormonal risk factors in black and white populations.

BACKGROUND: A crossover in breast carcinoma incidence at ages 45-49 years has been observed between black and white women, with blacks experiencing higher incidence at younger ages and lower incidence after age 50 years. Can this phenomenon be partially explained by the differences in the distributions of reproductive risk factors? This article focuses on the effects and distributions of age at first full term pregnancy (FFTP), parity, and oral contraceptive (OC) use in younger versus older and black and white populations. Effects of hormone replacement therapy (HRT) are also summarized. METHODS: A literature review was conducted and information integrated on the effects and distributions of reproductive and hormonal risk factors in black and white populations, the crossover effect of parity, and the Pike model of "breast tissue age." RESULTS: Overall, early age at FFTP and higher parity decreased risk for both races. Distributions of age at FFTP and parity varied widely between the two races. Based on the effects and distributions of age at FFTP and parity, the authors formulated the hypothesis that a crossover in incidence curves between the two races would be expected, rather than be considered an anomaly. Regarding OC use, generally a stronger increase in risk was observed for younger women than for older women. Regarding HRT, a recent meta-analysis observed an increased risk of 1.35 for 5 years of use or more. CONCLUSIONS: To promote public health in diverse populations, and to provide further insight into breast carcinoma etiology, research needs to focus on multicultural differences and similarities in the relation of hormonal risk factors and breast carcinoma.
