RESUMEN

INTRODUCTION: Women with unilateral breast cancer are at increased risk for having simultaneous cancer of the contralateral breast. Overall, earlier detection of contralateral breast cancer prevents the burden of additional surgery or chemotherapy rounds and is associated with higher overall survival. However, MRI screening for the contralateral breast is seldom done following an initial unilateral breast cancer diagnosis. The purpose of this study is to retrospectively evaluate patients with known, biopsy-proven malignancy who went on to obtain a breast MRI and were later found to have cancer of the contralateral breast.  Methods: This was a retrospective study that reviewed the charts of women aged over 18 years who were determined to have synchronous bilateral breast cancer from January 2017 to January 2022 at the University of Florida, Gainesville, FL. The study extracted data from this institution's cancer registry database, which provided information on patients with breast cancer diagnoses. The study conducted a review of mammography (MAM) and MRI imaging reports to ascertain the presence or absence of contralateral breast cancer identified by each respective imaging modality. Surgical pathology reports from the biopsy of the contralateral breast were reviewed to obtain information on the histological type of cancer and TNM (tumor, node, metastasis) staging. RESULTS: Of the 17 cases in which MAM missed contralateral cancer, follow-up MRI detected contralateral malignancy in 12 cases (70.59%) and subsequently changed management, resulting in additional imaging, biopsy, and eventual diagnosis and treatment of contralateral breast cancer. Examining the number of contralateral breast cancers detected by patients who had undergone MAM followed by MRI and those who had only undergone MAM, the study found that the detection rate of contralateral breast cancer from MAM was 45.45% (15/33). The tumor stages of the missed cancers were all T1 or Tis stage with one T1mi, and there was no nodal involvement.  Conclusion: In addition to its utility in staging breast cancers, MRI also has the superior ability to detect otherwise undetected contralateral breast malignancy. This retrospective study found that MRI imaging led to a considerable increase in the detection of contralateral cancer. The study found that these undetected contralateral breast cancers by MAM were often of lower staging with no nodal involvement, highlighting the opportunity for MRI to assist in early cancer detection while the patient's prognosis is still good. Its high cost should be balanced with staging and occult malignancy detection utility in future practice.

RESUMEN

The patient was an 84-year-old man who presented with a palpable, left breast mass. Following ultrasound, mammography, and ultrasound-guided core needle biopsy, the lesion was diagnosed as papillary carcinoma. Findings included a complex, cystic mass on ultrasound; a well-circumscribed, high-density lesion on mammogram; and a lack of highlighting of myoepithelial cells within fibrovascular cores on immunostaining. With this case report, we aim to add to the literature an additional example of breast papillary carcinoma in a male patient and its corresponding imaging and pathologic findings.

RESUMEN

A breast pseudoaneurysm (PSA) is a rare complication, with most cases reported following breast procedures. There are few reported cases of breast PSAs following blunt trauma. We report a rare case of right breast PSA in a 67-year-old female following a motor vehicle collision. The PSA was managed with a simple external pressure dressing over the breast and was found to have spontaneously thrombosed on a follow-up visit. Breast PSAs may be more common than expected due to their ability to spontaneously resolve and should be considered in patients presenting with a pulsatile breast mass or injury to the breast, especially when accompanied by a history of recent breast trauma or procedure.

RESUMEN

BACKGROUND: Risk stratification assessment of patients with non-ST elevation acute coronary syndrome (NSTE ACS) plays an important role in optimal management and defines the patient's prognosis. This study aimed to evaluate the ability of CHA2DS2-VASc-HSF score (comprising of the components of the CHA2DS2-VASc score with a male instead of female sex category, hyperlipidemia, smoking, and family history of coronary artery disease respectively) to predict the severity and complexity of CAD and its efficacy in stratification for major adverse cardiovascular events (MACE) in patients with NSTE ACS without known atrial fibrillation. METHODS: This study included 200 patients (males 72.5%, mean age 55.8 ± 10.1 years) who were admitted with NSTE ACS. CHA2DS2-VASC-HSF score was calculated on admission. Patients were classified into three groups according to their CHA2DS2-VASC-HSF score: low score group (< 2; 29 patients), intermediate score group (2-4; 83 patients), and high score group (≥ 5; 88 patients). Coronary angiography was conducted and the Syntax score (SS) was calculated. Clinical follow-up at 6 months of admission for the development of MACE was recorded. RESULTS: SS was significantly high in the high CHA2DS2-VASc-HSF score group compared with low and intermediate score groups. CHA2DS2-VASc-HSF score had a significant positive strong correlation with syntax score (r = 0.64, P < 0.001). Smoking, vascular disease, hyperlipidemia, and CHA2DS2-VASc-HSF score were independent predictors of high SS. For the prediction of severe and complex CAD, CHA2DS2-VASc-HSF score had a good predictive power at a cut-off value ≥ 5 with a sensitivity of 86% and specificity of 65%. Hypertension, vascular disease, high SS, and CHA2DS2-VASc-HSF score were independent predictors of MACE. CHA2DS2-VASC-HSF score ≥ 4 was identified as an effective cut-off point for the development of MACE with 94% sensitivity and 70% specificity. CONCLUSIONS: CHA2DS2-VASC-HSF score is proposed to be a simple bedside score that could be used for the prediction of the severity and complexity of CAD as well as a risk stratification tool for the development of MACE in NSTE ACS patients.

RESUMEN

BACKGROUND: Despite the promise of oral immunotherapy (OIT) to treat food allergies, this procedure is associated with potential risk. There is no current agreement about what elements should be included in the preparatory or consent process. OBJECTIVE: We developed consensus recommendations about the OIT process considerations and patient-specific factors that should be addressed before initiating OIT and developed a consensus OIT consent process and information form. METHODS: We convened a 36-member Preparing Patients for Oral Immunotherapy (PPOINT) panel of allergy experts to develop a consensus OIT patient preparation, informed consent process, and framework form. Consensus for themes and statements was reached using Delphi methodology, and the consent information form was developed. RESULTS: The expert panel reached consensus for 4 themes and 103 statements specific to OIT preparatory procedures, of which 76 statements reached consensus for inclusion specific to the following themes: general considerations for counseling patients about OIT; patient- and family-specific factors that should be addressed before initiating OIT and during OIT; indications for initiating OIT; and potential contraindications and precautions for OIT. The panel reached consensus on 9 OIT consent form themes: benefits, risks, outcomes, alternatives, risk mitigation, difficulties/challenges, discontinuation, office policies, and long-term management. From these themes, 219 statements were proposed, of which 189 reached consensus, and 71 were included on the consent information form. CONCLUSION: We developed consensus recommendations to prepare and counsel patients for safe and effective OIT in clinical practice with evidence-based risk mitigation. Adoption of these recommendations may help standardize clinical care and improve patient outcomes and quality of life.

RESUMEN

BACKGROUND: Although oral immunotherapy (OIT) for food allergy is a reasonable treatment option, barriers to this procedure's implementation have not been extensively evaluated from a patient perspective. OBJECTIVE: We evaluated the barriers patients face during OIT administration, including anxiety and taste aversion, and the role of health care professionals, especially dietitians. METHODS: A survey in Canada and the United States involved families currently enrolled in food OIT programs. RESULTS: Of responses from 379 participants, fear of reaction was the most common barrier to OIT initiation, with 45.6% reporting it being a "very significant" barrier with other fears reported. However, taste aversion represented the prominent obstacle to continuation. Taste aversion was associated with a slower buildup (P = .02) and a reduction in dose (P = .002). Taste aversion was a strongly age-dependent barrier for initiation (P < .001) and continuation (P < .002), with older children over 6 years of age reporting it as a very significant barrier (P < .001). Boredom was reported as a concern for specific allergens such as peanut, egg, sesame, and hazelnuts (P < .05), emphasizing the need for diverse food options. Notably, 59.9% of respondents mixed OIT foods with sweet items. Despite these dietary concerns, dietitians were underutilized, with only 9.5% of respondents having seen a dietitian and the majority finding dietitian support helpful with greater certainty about the exact dose (P < .001). CONCLUSIONS: Taste aversion and anxiety represent primary patient-related barriers to OIT. Taste aversion was highly age dependent, with older patients being more affected. Dietitians and psychology support were underutilized, representing a critical target to improve adherence and OIT success.

RESUMEN

OBJECTIVE: To compare outcomes between benign intraductal papillomas diagnosed on core need biopsy that were excised (BIP-E) versus those that were followed-up (BIP-F) at our institution. METHODS: Patients were identified by an electronic data base search from January 2010 to October 2016. After exclusions, clinical, radiological and histologic variables were evaluated and biopsy and excision slides reviewed. RESULTS: 110 BIP from 104 females were analyzed. 84 BIP were excised and 26 BIP were followed up (mean 43.3 months, range 7-93 months).11 patients in BIP-E group had atypia on excision. There were no statistically significant differences between BIP-E with atypia and BIP-E without, except for clinical presentation with pain/discomfort (p â€‹= â€‹0.015) in the former. There were no true upgrades to malignancy in both groups on follow up. One patient from each group developed a new breast cancer distant from IP site after nearly 4 years of uneventful follow-up. CONCLUSION: Clinical follow up is an oncologically safe alternative for radiologically concordant BIP. Excision may be considered if a diagnosis of atypia would impact surveillence and chemoprevention recommendations.

RESUMEN

BACKGROUND: While we strive to live with SARS-CoV-2, defining the immune response that leads to recovery rather than severe disease remains highly important. COVID-19 has been associated with inflammation and a profoundly suppressed immune response. OBJECTIVE: To study myeloid-derived suppressor cells (MDSCs), which are potent immunosuppressive cells, in SARS-CoV-2 infection. RESULTS: Patients with severe and critical COVID-19 showed higher frequencies of neutrophilic (PMN)-MDSCs than patients with moderate illness and control individuals (P = .005). Severe disease in individuals older and younger than 60 years was associated with distinct PMN-MDSC frequencies, being predominantly higher in patients of 60 years of age and younger (P = .004). However, both age groups showed comparable inflammatory markers. In our analysis for the prediction of poor outcome during hospitalization, MDSCs were not associated with increased risk of death. Still, patients older than 60 years of age (odds ratio [OR] = 5.625; P = .02) with preexisting medical conditions (OR = 2.818; P = .003) showed more severe disease and worse outcome. Among the immunological parameters, increased C-reactive protein (OR = 1.015; P = .04) and lymphopenia (OR = 5.958; P = .04) strongly identified patients with poor prognosis. CONCLUSION: PMN-MDSCs are associated with disease severity in COVID-19; however, MDSC levels do not predict increased risk of death during hospitalization.

RESUMEN

Monocytes in hepatitis C virus (HCV) infection play a critical role in chronic liver inflammation and fibrosis. We studied circulating monocytes and monocyte receptors in patients with HCV infection who were naive to treatment and those who received direct acting antiviral therapy and achieved sustained virological response. CD64+ CCR2+ (M1-like) and CD206+ CD163+ CX3CR1+ (M2-like) monocyte numbers and receptor expression were evaluated by flow cytometry. Higher expression of the monocyte chemokine receptor CCR2 predicted the severity of liver fibrosis, independent of successful treatment and viral clearance (R2 = 0.235, p = 0.002), whereas monocyte CX3CR1 expression was lower in both treated and untreated patients compared with controls (p = 0.011). The expression of the scavenger receptor CD163 was lower in patients with successful treatment (p = 0.005), supporting its role as a marker of treatment response. CD64+ CCR2+ (M1-like) and CD206+ CD163+ CX3CR1+ (M2-like) monocyte numbers were not altered with fibrosis progression or treatment response. Our findings reflect the diverse functions of monocytes in liver inflammation, fibrosis, and therapy. However, HCV clearance did not lead to complete monocyte reconstitution. Targeting monocytes and their chemokine receptors bears therapeutic potential to reduce liver fibrosis and improve disease outcome.

RESUMEN

Monocytes have been linked to the pathogenesis of immune thrombocytopenia (ITP) because of their role in autoantibody-mediated platelet phagocytosis. However, monocytes constitute unique populations with major differences in expression for surface Fcγ receptors (FcγRs). Thus, we evaluated monocytes in whole blood samples from patients with newly diagnosed and chronic ITP. Monocyte subpopulations were identified phenotypically by flow cytometry and defined according to the surface expression of CD14 (lipopolysaccharide receptor) and of CD16 (low-affinity Fcγ receptor III) into classical (CLM), intermediate (INTM) and nonclassical (non-CLM) monocytes. We also examined the expression of FcγRI/CD64 and FcγRIII/CD16 by monocyte subpopulations. Newly diagnosed patients showed a decrease in non-CLM, expressed as a relative percentage of total monocytes compared with controls and chronic ITP patients. Both non-CLM and INTM of newly diagnosed patients closely correlated with platelet count. These monocyte subpopulations showed significantly enhanced CD64 expression in newly diagnosed patients. On the contrary, patients with chronic ITP presented higher non-CLM in percentage than controls and concomitant lower CLM and total monocytes, in percentage and number. The expression of CD64 was increased by all monocyte subpopulations, CLM, INTM, and non-CLM in chronic patients. In conclusion, differences in monocyte subpopulations, together with enhanced expression of FcγRI/CD64 are evident in patients with ITP.

RESUMEN

Inflammatory breast cancer (IBC) is an aggressive form of breast carcinoma. Bilateral occurrences of IBC within a short time frame are rare, particularly without significant surgical intervention. This case presents a patient with contralateral recurrence of IBC less than a year after the initial diagnosis. A 39-year-old female was diagnosed with stage IV inflammatory breast cancer in her left breast. Less than a year later, extensive disease was found in her right breast. The patient had received incomplete treatment for the left IBC due to barriers to accessing care. Imaging confirmed the presence of inflammatory breast cancer in the contralateral breast, along with regional adenopathy and metastases. The patient began a chemotherapy regimen similar to her previous treatment. This case highlights the uncommon occurrence of contralateral recurrence of IBC and the hypothesized mechanism of lymphatic spread, suggesting local metastasis rather than a new primary tumor. The patient's incomplete treatment and lack of surgical intervention likely contributed to the development of contralateral IBC. The case underscores the importance of magnetic resonance imaging (MRI) in evaluating soft tissue and lymphatic changes in IBC. Barriers to care negatively impact prognosis, emphasizing the need for timely follow-up, diagnostic imaging, and oncologic therapy for successful treatment.

RESUMEN

Introduction Early breast cancer detection with screening mammography has been shown to reduce mortality and improve breast cancer survival. This study aims to evaluate the ability of an artificial intelligence computer-aided detection (AI CAD) system to detect biopsy-proven invasive lobular carcinoma (ILC) on digital mammography. Methods This retrospective study reviewed mammograms of patients who were diagnosed with biopsy-proved ILC between January 1, 2017, and January 1, 2022. All mammograms were analyzed using cmAssist® (CureMetrix, San Diego, California, United States), which is an AI CAD for mammography. The AI CAD sensitivity for detecting ILC on mammography was calculated and further subdivided by lesion type, mass shape, and mass margins. To account for the within-subject correlation, generalized linear mixed models were implemented to investigate the association between age, family history, and breast density and whether the AI detected a false positive or true positive. Odds ratios, 95% confidence intervals, and p-values were also calculated. Results A total of 124 patients with 153 biopsy-proven ILC lesions were included. The AI CAD detected ILC on mammography with a sensitivity of 80%. The AI CAD had the highest sensitivity for detecting calcifications (100%), masses with irregular shape (82%), and masses with spiculated margins (86%). However, 88% of mammograms had at least one false positive mark with an average number of 3.9 false positive marks per mammogram. Conclusion The AI CAD system evaluated was successful in marking the malignancy in digital mammography. However, the numerous annotations confounded the ability to determine its overall accuracy and this reduces its potential use in real-life practice.

RESUMEN

Due to its rarity, literature pertaining to radiation-associated breast angiosarcoma (RAS) remains sparse, with most studies focusing on retrospective review. Of more significant concern is the ambiguity of screening recommendations and modalities used to detect RAS, with current guidelines focusing on yearly mammographic imaging for women who underwent lumpectomy with radiation. Unfortunately, routine post-cancer screening has demonstrated low sensitivity in detecting RAS, often mistaking it for benign changes in roughly half of cases. We present an 83-year-old woman initially diagnosed with stage 1 invasive ductal carcinoma of the left breast who underwent a lumpectomy followed by radiation with 6040 cGy. Five years after her initial diagnosis, the patient noticed a suspicious lesion which then led her to undergo multiple modalities of imaging that described benign features. After continued concern, a biopsy was taken that demonstrated RAS of the left breast within the irradiated site. The patient underwent further radiation and declined surgical intervention. Routine screening with mammography and ultrasonography following breast radiation treatment are not sensitive modalities in detecting RAS. High-risk patient groups treated with greater than 0.5 Gy of radiation with concerning physical features 2-10 years after treatment should undergo MRI with biopsy at the initial concern to rule out angiosarcoma. Benign findings on imaging with patients in these groups should also consider biopsy.

RESUMEN

Phyllodes tumors are rare breast neoplasms that share many clinical characteristics with fibroadenomas, their benign counterpart. Despite their shared features, few reports have been made about the potential mechanisms by which a fibroadenoma can convert into a phyllodes tumor. This case report describes a large phyllodes tumor presenting in a 50-year-old female patient with a history of an excised biopsy-proven fibroadenoma eight years prior. Here, we exhibit our imaging findings and discuss plausible mechanisms for the conversion of a fibroadenoma into a phyllodes tumor, including genomic alterations.

RESUMEN

While the historic management of food allergy includes avoidance strategies and allergic reaction treatment, oral immunotherapy (OIT) approaches have become more commonly integrated into therapeutic approaches. International guidelines, phase 3 trials and real-world experience have supported the implementation of this procedure. However, OIT is an elective, rarely curative procedure with inherent risks that necessitates an increased degree of health literacy for the patients and families. Families assume the responsibility of amateur healthcare providers to ensure the daily safe administration of the allergenic food. As such, it is incumbent upon physicians to ensure that families are prepared for this role. A thorough educational and shared decision-making approach is necessary during the counselling and consent process to adequately inform the families. Educated discussion about the efficacy and patient-centred effectiveness, therapeutic alternatives and family goals is required to align physician and patient expectations. A frank discussion about the struggles, practical challenges, risks and contraindications can help to develop an understanding of the risk mitigation strategies employed to maintain safety. Physicians should develop a proactive approach to educate families about this, at times, burdensome procedure. This educational approach should encourage ongoing support starting prior to consent through the maintenance visits. By preparing families for their unique management role, physicians can help ensure the safe and successful integration of OIT into the therapeutic offering for the management of food allergies.

RESUMEN

Background: Health disparities among minority groups, especially African Americans, can limit their access to quality medical care and lead to disproportionate medical management and disease outcomes. The aim of this study was to compare the COVID-19-related change in mammogram volumes and cancer detection at two affiliated academic breast centers, one that serves a predominantly African American patient population and one that serves a predominantly non-African American patient population. Materials and methods: For the purpose of anonymity, racial demographics were collected and the center with a higher African American patient population was designated as institution A, while the center with a higher non-African American patient population was designated as institution B. Careful selection of the two breast centers was instituted in order to limit the impact of potential confounders other than race.An Institutional Review Board (IRB) exemption was obtained and two Mammography Quality Standards Act (MQSA) reports were generated; one for March 2020 through September 2020, during the height of the COVID-19 pandemic, and one for March 2019 through September 2019 to serve as the pre-pandemic control group. The i2b2 Query Analysis Tool® was used to obtain racial demographic data and compare the percent change in screening and diagnostic mammograms, image-guided biopsies, total cancers diagnosed by imaging, and percent of minimal cancers for both institutions. Results: Screening mammograms and breast cancer detection decreased in 2020 compared to 2019 at both institutions. However, the percent change from 2019 to 2020 was greater at institution A than at institution B. Percent minimal cancers, an indicator of early-stage breast cancer also decreased more drastically at institution A than at institution B. Interestingly, the total number of diagnostic exams and image-guided biopsies increased in 2020 at institution B, whereas both decreased at institution A. Conclusion: The COVID-19 pandemic may lead to worsening racial disparities in breast cancer screening. In an effort to narrow future disparity, it is crucial for radiologists and other health care providers to be aware of this inequality and educate all women on the importance of obtaining routine screening mammography. More studies are needed.

RESUMEN

We present the case of a 52-year-old female who presented with a rapidly enlarging right breast mass. An initial breast ultrasound showed a solid mass with cystic components and posterior acoustical enhancement and mammography showed a mass in the same area without calcifications. Biopsy of the lesion revealed spindle cell carcinoma of the breast. To date, the patient has undergone radiation therapy and simple mastectomy and will receive post-operative radiotherapy in the coming months.

RESUMEN

BACKGROUND: Blacks are dying from the novel coronavirus of 2019 (COVID-19) at disproportionate rates and tend to have more COVID-19 vaccine hesitancy than Whites. These disparities may be attributable to health knowledge and government/medical mistrust stemming from negative experiences with the medical system historically and presently (e.g., the Tuskegee Experiment, provider maltreatment). METHOD: The present study assessed COVID-19 vaccine hesitancy and the effectiveness of a 1.5 h, dialogue-based, web intervention hosted by an academic-community partnership team. The webinar included approximately 220 male and female, English speaking, Black churchgoers in the western U.S. The webinar focused on the psychology of fear and facts about the vaccine development. RESULTS: The sample was mostly females who had higher vaccine hesitancy than men. A third of participants feared hospitalization if they contracted COVID-19. Many participants reported that learning facts about COVID-19 was most impactful. Statistical analyses indicated an increased willingness to get vaccinated after the webinar in comparison to before (t(25) = -3.08, p = 0.005). CONCLUSION: The findings suggest that virtual webinars may be effective at reducing COVID-19 vaccine hesitancy among Black churchgoers and may be applicable in addressing other health behaviors.

RESUMEN

A common presenting symptom for female patients is nipple discharge. Therefore having a background on how to manage is necessary for appropriately identifying and diagnosing the underlying etiology. The two most utilized imaging studies are diagnostic mammography and ultrasound. It can be difficult to identify a source/cause with mammography due to decreased sensitivity with also variable results seen with ultrasound. Advanced imaging such as MRI is becoming increasingly utilized limiting the need for ductography for diagnosis. In this case report, we discuss a rare case presentation of spontaneous nipple discharge.

RESUMEN

OBJECTIVE: Asthma is a chronic disorder of the airways, in which chemokines coordinate airway inflammation and determine its severity. We aimed to study the chemokine interferonγ-inducible protein 10 kDa (IP10/CXCL10), a member of the CXC receptor 3 (CXCR3) ligand family, at the protein level in the serum of children, to evaluate the association between CXCL10 and exacerbations of childhood asthma. METHODS: Patients experiencing an asthma exacerbation (42 patients) and stable patients (43 patients) were investigated for serum CXCL10 levels. RESULTS: Patients with an asthma exacerbation expressed significantly higher CXCL10 levels in the serum than stable patients (p < 0.001). Additionally, CXCL10 values were elevated in severe asthma compared with moderate and mild disease (p < 0.001). In patients experiencing asthma exacerbations, higher values of CXCL10 were observed in atopic patients compared with non-atopic patients (p = 0.027) and in uncontrolled and partly controlled patients compared with controlled patients (p = 0.046). CONCLUSIONS: CXCL10 is proposed as an inflammatory serum marker for asthma exacerbations and worsening asthma symptoms. The levels of CXCL10 are representative of the clinical severity of asthma.
