Caring for the Deaf, Hard-of-Hearing, Blind, and Low-Vision Patients in the Breast Center.

Two heterogeneous populations with widely varying needs are being increasingly encountered in breast care facilities: blind or low vision patients and deaf or hard of hearing patients. The Americans with Disabilities Act and the Rehabilitation Act mandate that all governments, businesses, and not-for-profit organizations provide effective communication to those facing hearing, vision, or speech communication disabilities and that the provided communication is equally effective as that provided to those lacking communication disabilities. It is vitally important that breast center providers understand the requirements put forth by these acts in the provision of patient care, which includes interactions with the patient as well as their family members and partner. Breast center providers must identify each patient's individual needs and preferred method of communication. Options to assist in communication for the deaf or hard of hearing include the use of text conversations, preprinted or accessible video health care education material, and dedicated American Sign Language or video interpreters. Attention to breast imaging facility design, access to large print or braille documents, and the use of qualified readers can aid in improving access and communication for the blind or low-vision individual. All members of the breast health team, from scheduling staff to front office personnel, technologists, and breast imaging radiologists, should understand how to respectfully communicate with and identify the needs of patients facing these challenges.

JOURNAL CLUB: Scatter Radiation Dose From Digital Screening Mammography Measured in a Representative Patient Population.

OBJECTIVE: The purpose of this study was to quantify the amount of scatter radiation received at the skin surface overlying the thyroid gland, salivary gland, lens of the eye, sternum, and uterus during a routine screening digital mammographic examination measured in a representative patient population. SUBJECTS AND METHODS: The subjects were 207 women without symptoms with varied body mass indexes who underwent annual screening mammography while wearing six optically stimulated luminescence dosimeters placed at the bridge of the nose, right submandibular gland, right and left thyroid lobes, mid sternum, and 2 cm caudal to the umbilicus to assess scatter radiation dose to the skin. RESULTS: The average scatter radiation doses at the skin surface during digital screening mammography in the representative population of women were as follows: overlying the right lobe of the thyroid, 0.24 mGy; left lobe of the thyroid, 0.25 mGy; salivary gland, 0.2 mGy; bridge of the nose, 0.025 mGy; sternum, 0.87 mGy; and umbilicus, 0.011 mGy. The scatter radiation doses at the umbilicus and the bridge of the nose were too low to measure with statistical confidence. Scatter radiation dose increased with increasing body mass index and increasing breast compression thickness. CONCLUSION: Scatter radiation dose at the skin overlying organs of interest is a small fraction of the entrance skin dose to the breast. The low levels of scatter radiation measured do not support delaying clinically indicated mammography during early pregnancy.

Nonpuerperal mastitis and subareolar abscess of the breast.

OBJECTIVE: The purpose of this article is to show radiologists how to readily recognize nonpuerperal subareolar abscess and its complications in order to help reduce the time to definitive therapy and improve patient care. To achieve this purpose, the various theories of pathogenesis and the associated histopathologic features are reviewed; the typical clinical characteristics are detailed in contrast to those seen in lactational abscess and inflammatory breast cancer; the common imaging findings are described with emphasis on the sonographic features; correlative pathologic findings are presented to reinforce the imaging findings as they pertain to disease origins; and the various treatment options are reviewed. CONCLUSION: Nonpuerperal subareolar mastitis and abscess is a benign breast entity often associated with prolonged morbidity. Through better understanding of the underlying disease process the imaging, physical, and clinical findings of this rare process can be more readily recognized and treatment options expedited, improving patient care.

A succinct rating scale for radiology report quality.

CONTEXT: Poorly written radiology reports are common among residents and are a significant challenge for radiology education. While training may improve report quality, a professionally developed reliable and valid scale to measure report quality does not exist. OBJECTIVES: To develop a measurement tool for report quality, the quality of report scale, with rigorous validation through empirical data. METHODS: A research team of an experienced psychometrician and six senior radiologists conducted qualitative and quantitative studies. Five items were identified for the quality of report scale, each measuring a distinct aspect of report quality. Two dedicated training sessions were designed and implemented to help residents generate high-quality reports. In a blinded fashion, the quality of report scale was applied to 804 randomly selected reports issued before (n = 403) and after (n = 401) training. Full-scale psychometrical assessments were implemented onto the quality of report scale's item- and scale-scores from the reports. The quality of report scale scores were correlated with report professionalism and attendings' preference and were compared pre-/post-training. RESULTS: The quality of report scale showed sound psychometrical properties, with high validity and reliability. Reports with higher quality of report scale score were more professional and preferable by attendings. Training improved the quality of report scale score, empirically validating the quality of report scale further. CONCLUSION: While succinct and practitioner friendly, the quality of report scale is a reliable and valid measure of radiology report quality and has the potential to be easily adapted to other fields such as pathology, where similar training would be beneficial.

Pediatric and adolescent breast masses: a review of pathophysiology, imaging, diagnosis, and treatment.

OBJECTIVE: Pediatric breast masses are relatively rare and most are benign. Most are either secondary to normal developmental changes or neoplastic processes with a relatively benign behavior. To fully understand pediatric breast disease, it is important to have a firm comprehension of normal development and of the various tumors that can arise. Physical examination and targeted history (including family history) are key to appropriate patient management. When indicated, ultrasound is the imaging modality of choice. The purpose of this article is to review the benign breast conditions that arise as part of the spectrum of normal breast development, as well as the usually benign but neoplastic process that may develop within an otherwise normal breast. Rare primary carcinomas and metastatic lesions to the pediatric breast will also be addressed. The associated imaging findings will be reviewed, as well as treatment strategies for clinical management of the pediatric patient with signs or symptoms of breast disease. CONCLUSION: The majority of breast abnormalities in the pediatric patient are benign, but malignancies do occur. Careful attention to patient presentation, history, and clinical findings will help guide appropriate imaging and therapeutic decisions.

Factors associated with imaging and procedural events used to detect breast cancer after screening mammography.

OBJECTIVE: The purpose of this study was to characterize the type and frequency of diagnostic evaluations after screening mammography and to summarize their association with the likelihood of biopsy and subsequent breast cancer diagnosis. MATERIALS AND METHODS: The data source was 584,470 women with no previous breast cancer from six states in the Breast Cancer Surveillance Consortium. In this observational study, we linked data from 1,207,631 routine screening mammograms performed between January 1, 1996, and December 31, 2002, to data on additional imaging, interventional procedures, and biopsy outcome (benign or malignant). Additional examinations were categorized into diagnostic mammography, sonography, or both. Events were further subdivided by whether they were performed on the same day as the screening examination and whether patients reported breast symptoms. Logistic regression analysis was used to examine the association between additional evaluation performed and the likelihood of biopsy and the likelihood of subsequent breast cancer diagnosis after adjustment for patient and screening mammographic characteristics. RESULTS: Most (92%) of the screening examinations did not include additional imaging. The probability of biopsy ranged from 0.4% for examinations with no follow-up to 20.1% for those with diagnostic mammography and sonography on the same day as screening among women without symptoms and from 2.1% for those with no follow-up to 18.9% for those with diagnostic mammography and sonography on a day different from screening among women with symptoms. Thirty percent of women without symptoms who underwent biopsy had cancer, whereas 27.1% of women with symptoms who underwent biopsy had cancer. Women who underwent biopsy after screening mammography with diagnostic mammography and sonography on the same day had the highest probability of breast cancer (37.6% among women without symptoms, 36.4% among women with symptoms), whereas those who underwent only sonography performed at a later date had the lowest probability of breast cancer (11.9% among women without symptoms, 17.1% among women with symptoms). CONCLUSION: Women who undergo screening mammography followed by diagnostic mammography and sonography have a high probability of undergoing biopsy and having the biopsy result of breast cancer when follow-up imaging is performed on the same day as screening mammography whether or not breast symptoms are present. Biopsy performed after sonography in the absence of diagnostic mammography had a low yield of breast cancer.

Discovery of breast cancers within 1 year of a normal screening mammogram: how are they found?

PURPOSE: We sought to determine how breast cancers that occur within 1 year after a normal mammogram are discovered. METHODS: Using population-based mammography registry data from 2000-2002, we identified 143 women with interval breast cancers and 481 women with screen-detected breast cancers. We surveyed women's primary care clinicians to assess how the interval breast cancers were found and factors associated with their discovery. RESULTS: Women with interval cancers were twice as likely to have a personal history of breast cancer (30.1%) as women with screen-detected cancers (13.6%). Among women with interval cancers, one half of the invasive tumors (49.5%) were discovered when women initiated a health care visit because of a breast concern, and 16.8% were discovered when a clinician found an area of concern while conducting a routine clinical breast examination. Having a lump and both a personal and a family history of breast cancer was the most common reason why women initiated a health care visit (44%) (P <.01). CONCLUSIONS: Women with interval cancers are most likely to initiate a visit to a primary care clinician when they have 2 or more breast concerns. These concerns are most likely to include having a lump and a personal and/or family history of breast cancer. Women at highest risk for breast cancer may need closer surveillance by their primary care clinicians and may benefit from a strong educational message to come for a visit as soon as they find a lump.

Hormone therapies in women aged 40 and older: prevalence and correlates of use.

CONTEXT: The objective of this paper is to report the prevalence and correlates of both prescription and non-prescription hormone use. DESIGN/SETTING/SAMPLE: Cross-sectional baseline study from a prospective cohort of 30,448 women receiving mammography in New Hampshire. MAIN OUTCOME MEASURES: Odds of prescription hormone and non-prescription hormone use. RESULTS: 29,851 women were included; 62% reported some use of prescription hormone therapy, with current long-term prescription hormone therapy users representing the largest group (25%). Among ever-users, estrogen only was the most commonly used preparation (71% versus 30% for estrogen and progestin combined). Both single agent estrogen and estrogen and progestin combined regimens were taken primarily for treatment of menopausal symptoms or disease prevention. Correlates for prescription hormone use included a family history of breast cancer (associated with decreased use-OR 0.88; 95% CI: 0.84, 0.93), and family history of heart disease (associated with increased use-OR 1.11; 95% CI: 1.06, 1.17). Ten percent of women reported ever use of phytoestrogens (over-the-counter hormones). Family history of breast cancer was a correlate of over-the-counter hormone use (OR 1.10; 95% CI: 1.01, 1.19). CONCLUSION: Management of menopausal symptoms and disease prevention were the main reasons for using prescription hormones, and health histories were important correlates of both prescription and over-the-counter hormone exposures. As evidence changes regarding risks and benefits of hormone exposure, primary care physicians should help women reassess their use of hormonal agents.

Likelihood of additional work-up among women undergoing routine screening mammography: the impact of age, breast density, and hormone therapy use.

BACKGROUND: Mammography screening can involve subsequent work-up to determine a final screening outcome. Understanding the likelihood of different events that follow initial screening is important if women and their health care providers are to be accurately informed about the screening process. METHODS: We conducted an analysis of additional work-up following screening mammography to characterize use of supplemental imaging and recommendations for biopsy and/or surgical consultation and the factors associated with their use. We included all events following screening mammography performed between 1/1/1998 and 12/31/1999 on a population-based sample of 37,632 New Hampshire women. We calculated adjusted odds ratios (OR) and 95% confidence intervals (CI) for supplemental imaging and recommended biopsy and/or surgical consultation as function of age, menopausal status and HRT use, breast density, and family history of breast cancer. RESULTS: Ninety-one percent of women (n = 34,445) did not require supplemental imaging. Among those who did (n = 3187), 84% had additional views, 9% ultrasound, and 7% received both. Supplemental imaging was affected by age (OR 0.84; 95% CI = 0.76-0.94 for 50-59; OR = 0.66; 95% CI = 0.58-0.75 for > or = 60 versus < 50), menopausal status, and HRT use (OR = 1.33; 95% CI = 1.21-1.47 for peri- or post-menopausal HRT users; OR = 1.14; 95% CI = 1.01-1.29 for premenopausal versus peri- or post-menopausal non-HRT users), breast density (OR = 1.43; 95% CI = 1.33-1.55 for dense versus fatty breasts) and family history (OR = 1.15; 95% CI = 1.06-1.25 for any versus none). In women with supplemental imaging, age (OR = 1.80; 95% CI = 1.11-2.90 for > or = 60, relative to <50) and imaging type (OR = 3.23; 95% CI = 2.38-4.38 for ultrasound with or without additional views versus additional views only) were significantly associated with biopsy and/or surgical consultation recommendation. In those with no supplemental imaging, breast density was associated with recommended biopsy and/or surgical consultation (OR = 1.53; 95% CI = 1.13-2.07 for dense versus fatty breasts). CONCLUSIONS: Breast density and HRT use are both independent predictors of use of supplemental imaging in women. With advancing age (age 60 and older), women were less likely to require follow-up imaging but more likely to receive a recommendation for biopsy and/or surgical consultation. This information should be used to inform women about the likelihood of services received as part of the screening work-up.

Life spans and senescent phenotypes in two strains of Zebrafish (Danio rerio).

Zebrafish have become a widely used model organism in developmental biology research. In order to initiate an experimental foundation for aging studies, we have determined some basic gerontological parameters for populations of outbred zebrafish, and the golden sparse strain. Outbred zebrafish manifested a mean life span of about 42 months, with the longest living individual surviving for 66 months. The golden sparse populations had a mean life span of 36 months and a maximum longevity of 58 months. Skeletal length at death increased with age, suggestive of indeterminate growth. A common age-related phenotype was spinal curvature. Radiographic analysis excluded bony changes as the cause of the spinal curvature, suggesting muscle abnormalities as a primary mechanism. These data and a growing abundance of related biological resources suggest that the zebrafish may be a compelling model organism for studies on aging.

Correlation between presumed sinusitis-induced pain and paranasal sinus computed tomographic findings.

BACKGROUND: The correlation between facial and/or head pain in patients clinically suspected of having sinusitis and actual localized findings on sinus computed tomographic (CT) imaging are poorly understood. OBJECTIVE: To prospectively evaluate the relationship of paranasal sinus pain symptoms with CT imaging. METHODS: Two hundred consecutive patients referred by otolaryngologists and internists for CT of the paranasal sinuses participated by completing a questionnaire immediately before undergoing CT. Three radiologists blinded to the patients' responses scored the degree of air/fluid level, mucosal thickening, bony reaction, and mucus retention cysts using a graded scale of severity (0 to 3 points). The osteomeatal complexes and nasolacrimal ducts were also evaluated for patency. Bivariate analysis was performed to evaluate the relationship between patients' localized symptoms and CT findings in the respective sinus. RESULTS: One hundred sixty-three patients (82%) reported having some form of facial pain or headache. The right temple/forehead was the most frequently reported region of maximal pain. On CT imaging the maxillary sinus was the most frequently involved sinus. Bivariate analysis failed to show any relationship between patient symptoms and findings on CT. Patients with a normal CT reported a mean 5.88 sites of facial or head pain versus 5.45 sites for patients with an abnormal CT. CONCLUSIONS: Patient-based responses of sinonasal pain symptoms fail to correlate with findings in the respective sinuses. CT should therefore be reserved for delineating the anatomy and degree of sinus disease before surgical intervention.
