Using a combination of superb microvascular imaging and other auxiliary ultrasound techniques to increase the accuracy of gray-scale ultrasound for breast masses.

BACKGROUND: Breast ultrasound is highly sensitive, but its specificity is not as high for detecting malignant lesions. Auxiliary modalities like elastography, Color and Power Doppler ultrasound are used as adjuncts to yield both a high sensitivity and specificity. Superb microvascular imaging (SMI) is a newer modality with more accuracy for detecting breast lesions. In this study, our goal was to investigate the role of SMI as an adjunct to ultrasound and find a suitable combination model for the evaluation of breast masses. METHODS: In this cross-sectional study, 132 women with 172 breast masses who underwent ultrasound-guided biopsy were included.. The ultrasound features of the lesion, the strain ratio in strain elastography, the number of vessels for each lesion, their morphology and distribution in Doppler and Power Doppler ultrasound and SMI were recorded for each lesion. A vascular score and a vascular ratio were defined. RESULTS: In the histologic examination, 31 lesions (18%) were malignant and 141 lesions (82%) were benign. The vascular score was more accurate than the vascular ratio in all three modalities. The predictive ability of strain ratio was higher than Doppler and Power Doppler ultrasound and SMI. Adding SMI alone to ultrasound increased the specificity from 46.10% to 61.2% and the accuracy from 55.80% to 70.11%. In the combination of ultrasound with other modalities, the best was the combination of ultrasound, strain elastography, and SMI; which yielded a specificity and sensitivity of 100% and 74.4%, respectively. CONCLUSION: Adding SMI and STE modalities as adjuncts to ultrasound lowers the chance of missing malignant lesions and reduces unnecessary biopsies of breast lesions. A study with a larger sample size using this combination model to evaluate the accuracy with greater precision is recommended.

Imiquimod as a new treatment in refractory idiopathic granulomatous mastitis: report of two cases.

INTRODUCTION: Idiopathic granulomatous mastitis (IGM) is a rare chronic inflammatory lesion of the breast that mimics breast cancer or infection. Immunological pathogenesis is strongly suggested for the disease. REASON FOR THE REPORT: The treatment remains controversial, comprising a spectrum from observation or NSAIDs to immunosuppressive agents and surgery. Intractable cases are not uncommon and represent a major treatment challenge. Therefore in this study, we examine the effect of a topical immunomodulator agent, imiquimod, on refractory IGM. Patient 1 had IGM for 9 months and had not responded to the existing treatments. She responded to a 7-week course of imiquimod. In patient 2, the disease had begun 4 months sooner and had been resistant to all treatments; it responded to imiquimod after 4 weeks. Ulcers appeared on the skin of both patients but resolved safely. OUTCOME: Both patients were very satisfied with the results. Imiquimod can be an appropriate local treatment with limited adverse effects in refractory IGM. We propose similar studies to assess the efficacy of imiquimod in IGM further, paying attention to the possibility of developing skin wounds.

Need assessment for the content of educational programs about breast cancer from the viewpoint of unaffected women.

BACKGROUND: Breast cancer is the most common cancer among females, and early diagnosis is possible in case the patients seek medical attention on time. For this to come true, they must know about the existence and risks of the disease and be aware of the appropriate attitude and actions toward prevention or early diagnosis. However, we see that women have unanswered questions about these issues. In this study, we sought to investigate healthy women's information needs about breast cancer from their own perspective. METHODS: This prospective study was carried out by using the maximum variation sampling, and theoretical saturation to reach sample saturation. Women who came to different clinics of Arash Women's Hospital (except the Breast Clinic) during two months were entered in the study. Participants were asked to write down all the questions and subjects they would like to be explained in a breast cancer educational program. The questions were reviewed and categorized after every fifteen consecutive forms were filled until there was not even one new question. Afterwards, all the questions were reviewed and matched based on their similarity and repeated items were eliminated. Finally, questions were organized according to their common topics and the range of details they comprised. RESULTS: Sixty patients were included in the study, and 194 questions were gathered and categorized according to common scientific terms, resulting in 63 questions in 5 categories. CONCLUSIONS: Many studies have been conducted on breast cancer education, but none have addressed healthy women's personal queries. This study outlines the questions of unaffected women about breast cancer that need to be addressed in educational programs. The results can be used for development of educational material at community level. TRIAL REGISTRATION: This study was conducted as the preliminary phase of a study approved in Tehran University of Medical Sciences (Approval Code 99-1-101-46,455) and by the Ethics Committee of the University (Ethical Code IR.TUMS.MEDICINE.REC.1399.105).

Development, validation, and implementation of a Short Breast Health Perception Questionnaire.

BACKGROUND: Health status and perception can be assessed by general or disease-specific questionnaires, and disease specific questionnaires are more specific than general questionnaires. Considering the importance of breast health perception (BHP) in women's lives and the lack of any pertinent questionnaires, we performed this study to develop a valid and reliable short BHP questionnaire (BHPQ); and then used it to assess the participants' BHP. METHODS: We first designed and developed the instrument and then measured its inter-rater agreement (IRA), content validity including content validity index (I-CVI) and scale content validity index (S-CVI), and reliability (through internal consistency and test-retest). We then evaluated the BHP of eligible women with normal breasts and benign breast disorders who attended our breast clinic. RESULTS: The IRA index (78.6%) showed the optimal relevance and clarity of the questionnaire. The content validity was acceptable; with S-CVIs of 87.35 and 84.42 for clarity and relevance, respectively. The internal reliability was high (Cronbach's alpha = 0.93). Three questions were eliminated for internal consistency (intraclass correlation coefficient < 0.7) but the rest of the questions showed good and excellent reliability. In the next step, BHP in the 350 eligible participants showed an overall score of 43.89 ± 9.09. CONCLUSION: This study introduces a valid and reliable 11-item BHPQ. We propose its use in various circumstances throughout breast cancer screening, diagnosis, and treatment; and in the assessment of BHP in various physiologic and reproductive situations.

COVID-19 Outbreak and Consequent Delays in Schedules of the Breast Clinic: Effects on Patients' Breast and Emotional Symptoms.

OBJECTIVE: The pandemic of COVID-19 has affected many aspects of life, and emotional symptoms have been reported to worsen during this time. Also, elective visits in the Breast Clinic have been cancelled or postponed based on the priorities defined in local and international guidelines. Our aim was to investigate the effect of these delays on the breast symptoms and emotional status of our patients. MATERIALS AND METHODS: We called patients whose appointments should have taken place between March and May 2020. After asking for their consent to participate in the study, we asked questions about their breast and emotional symptoms and any worsening of these due to cancellation of their schedules because of the COVID-19 outbreak. We also inquired the relation of breast symptoms with news and thoughts about COVID-19, and if the patients or their close relatives or friends had been affected by COVID-19. We compared the worsening of breast symptoms in patients with and without a positive self- or family history of COVID-19. RESULTS: None of the breast or emotional symptoms had significantly got worse in the patients. Also, there was no significant difference between the two groups regarding the changes in their breast symptoms or emotional health. CONCLUSION: We believe that these results might be evidence in favor of the Breast Clinic triage system, which conforms to most international and specifically to our local recommended strategies.
