RESUMO

AIM: Determine the utility of prospective spinal ultrasound in infants of mothers with pregestational diabetes (PGDM) for the diagnosis of closed spinal dysraphism (SDs). METHODS: This prospective observational pilot study was completed at a tertiary care center between May 1, 2020 and December 30, 2022. Infants born to mothers with PGDM and with normal spinal physical examinations were included. A total of 25 mother-infant dyads were enrolled in the study and prospectively screened with spinal ultrasound. The study was registered on ClinicalTrials.gov (Identifier-NCT05033275). RESULTS: Twenty-five spinal ultrasounds were performed over the course of this study with three (8%) resulting in abnormal findings that required further imaging. Follow-up with magnetic resonance imaging found one case of tethered cord syndrome. CONCLUSION: Prospective screening in infants of mothers with PGDM found one case of tethered cord syndrome. This finding suggests that risk stratified screening of mothers with diabetes might be a reasonable approach to care.

RESUMO

OBJECTIVES: The physical exam component of a periodic health visit in the elderly has not been considered useful. Standard Medicare Wellness visits require no physical exam beyond blood pressure and most physicians perform limited exams during these visits. The objective of this study was to test the feasibility, potential benefit, and costs of performing a screening ultrasound (US) exam during Medicare Wellness visits. METHODS: A physician examiner at an academic internal medicine primary care clinic performed a screening US exam targeting important abnormalities of patients 65-85 years old during a Medicare Wellness visit. The primary care physician (PCP) recorded the follow-up items for each abnormality identified by the US examiner and assessed the benefit of each abnormality for the participant. Abnormality benefit, net exam benefit per participant, follow-up items and costs, participant survey results, and exam duration were assessed. RESULTS: Participants numbered 108. Total abnormalities numbered 283 and new diagnoses were 172. Positive benefit scores were assigned to 38.8%, neutral (zero) scores to 59.4%, and negative benefit scores to 1.8% of abnormalities. Net benefit scores per participant were positive in 63.9%, 0 in 34.3%, and negative in 1.8%. Follow-up items were infrequent resulting in 76% of participants without follow-up cost. Participant survey showed excellent acceptance of the exam. CONCLUSIONS: The US screening exam identified frequent abnormalities in Medicare Wellness patients. The assessed benefits were rarely negative and often mild to moderately positive, with important new chronic conditions identified. Follow-up costs were low when the PCPs were also US experts.

RESUMO

Digital breast tomosynthesis (DBT) has been widely implemented in place of 2D mammography, although it is less effective in women with extremely dense breasts. Breast ultrasound detects additional early-stage, invasive breast cancers when combined with mammography; however, its relevant limitations, including the shortage of trained operators, operator dependence and small field of view, have limited its widespread implementation. Automated breast sonography (ABS) is a promising technique but the time to interpret and false-positive rates need to be improved. Supplemental screening with contrast-enhanced magnetic resonance imaging (MRI) in high-risk women reduces late-stage disease; abbreviated MRI protocols may reduce cost and increase accessibility to women of average risk with dense breasts. Contrast-enhanced digital mammography (CEDM) and molecular breast imaging improve cancer detection but require further validation for screening and direct biopsy guidance should be implemented for any screening modality. This article reviews the status of screening women with dense breasts. KEY POINTS: • The sensitivity of mammography is reduced in women with dense breasts. Supplemental screening with US detects early-stage, invasive breast cancers. • Tomosynthesis reduces recall rate and increases cancer detection rate but is less effective in women with extremely dense breasts. • Screening MRI improves early diagnosis of breast cancer more than ultrasound and is currently recommended for women at high risk. Risk assessment is needed, to include breast density, to ascertain who should start early annual MRI screening.

RESUMO

PURPOSE OF REVIEW: Advanced mammographic imaging modalities have been implemented in clinical practices throughout the USA. The most notable and widely used has been the three-dimensional derivative of digital mammography, known as digital breast tomosynthesis (DBT). In this article, we review the screening and diagnostic applications of DBT, along with its limitations. We also briefly address several supplemental breast imaging modalities. RECENT FINDINGS: The accumulating evidence from both small and large-scale trials has shown a significant reduction in recall rates and slight increase in cancer detection rates when using DBT. However, the incremental increase in cancers detected remains less than that achieved with several supplemental imaging modalities, including whole-breast ultrasound, MRI, and MBI (molecular breast imaging). Other modalities, such as CEM (contrast-enhanced mammography) and CET (contrast-enhanced tomography), are also being investigated. Numerous studies have confirmed the added value of DBT and its increased cancer detection rate in both the screening and diagnostic settings. However, the superior sensitivity of supplemental imaging modalities renders them essential, especially in high-risk patients, and potentially those with dense breasts.

RESUMO

OBJECTIVE: To audit the development and success rate of prenatal detection of congenital heart defects (CHDs), and to evaluate the effectiveness of diagnostics performed in standardized scanning planes. SETTING: Department of Pediatrics, University Hospital Ostrava. DESIGN: Retrospective study. METHODS: Ultrasound examination of fetal heart (fetal echocardiography) was performed in the second trimester pregnancy. The observed region was the Moravian-Silesian region; the assessment was performed in the retrospective study performed between 2000- 2016. The knowledge of all significant heart defects in the region, processing of data from genetic reporting, further examination of all prenatal pathologies by a pediatric cardiologist, presence of a pediatric cardiologist at all autopsies, with a precise description of the defect, birth of a pathological new-born at a specialized centre. Analysis of detected CHDs was performed in relation to the ultrasound scans used. RESULTS: During the monitored 17-year period, a total of 748 (3.8 cases per 1,000 foetuses) of prenatally identified and postnatally significant CHDs were observed in the total population of 198,300 foetuses. There were 53% (393/748) CHDs detected prenatally and 47% (355/748) of cases were not prenatally recognized. The effectiveness of CHD screening has improved progressively, from the initial 10% up to the current 74%. The best results were obtained using the basic four-chamber (4CH) scan; the results in practice gradually decreased, from the basic 4CH projection to the aortic arch. CONCLUSION: The effectiveness of prenatal detection of congenital heart defects gradually improves, namely in cases of hypoplasia and significant ventricular anomalies, with up to 100% prenatally detected cases in the past three years. The level of detection statistically decreases, from the four-chamber projection to out-flow tracts, great arteries and the aortic arch. Congenital heart defect is generally well detectable prenatally, and is usually observed as an isolated anomaly. The most important factors include a precise diagnosis, overall examination of the pregnancy and correct counselling provided for the affected family.

RESUMO

BACKGROUND: Ultrasound (US) screening is not currently recommended as a routine screening modality in the general population of average risk. The cancer detection yield and positive predictive value in an average risk general population who undergo breast screening by experienced radiologists is unclear. PURPOSE: To determine the performance of screening breast US in women at an average risk for breast cancer undergoing breast screening by experienced radiologists. MATERIAL AND METHODS: This study received institutional review board approval, and informed consent was waived. A retrospective review of our database revealed 1526 women who underwent prevalence screening US at a single health screening center and had negative findings on digital mammography (MG). The Breast Imaging and Reporting Data System (BI-RADS) final assessments of the breast US were analyzed retrospectively, with the reference standard defined as a combination of pathology and a 12-month follow-up. The cancer detection rate and positive predictive value (PPV2) of the biopsies were calculated according to breast density. RESULTS: The average time to perform a screening US examination was 15-20 min. Of 1526 women, 1095 (71.8%) were classified as BI-RADS category 1 or 2; 340 (22.3%) were classified as category 3; and 91 (6.0%) were classified as category 4. Five malignant lesions were found in women with dense breasts. The overall cancer detection rate was 3.3, and the cancer detection rate for dense breasts was 5.1 per 1000 screens (4.1 per 1000 screens [heterogeneously dense breast], 7.7 per 1000 screens [extremely dense breast]). The PPV2 for biopsies was 5.3%. CONCLUSION: The radiologist-performed screening US offered to women with an average risk and dense breasts can detect additional mammographically occult breast cancers. In screening US, a relatively high rate of BI-RADS category 3 and 4 lesions was observed.

RESUMO

PURPOSE: To describe factors associated with screening ultrasound ordering and determine whether adoption of state-level breast density reporting laws was associated with changes in ordering rates. MATERIALS AND METHODS: We performed a cohort study using National Ambulatory Medical Care Survey data for 2007 to 2015. We included preventive office visits for women aged 40 to 74 years without breast symptoms and signs or additional reasons requiring ultrasound ordering. Multivariate logistic regression was used to identify changes in ultrasound ordering rates pre- versus post-state-level density reporting laws, accounting for patient-, physician-, and practice-level characteristics. Analyses were weighted to account for the multistage probability sampling design of National Ambulatory Medical Care Survey. RESULTS: Our sample included 12,787 visits over the 9-year study period. Overall, 28.9% (3,370 of 12,787) of women underwent a breast examination and 22.1% (2,442 of 12,787) had a screening mammogram ordered. Only 3.3% (379 of 12,787) had screening ultrasound ordered. Screening ultrasounds were ordered more frequently for younger women (rate ratio [RR] 0.8 per 10-year increase in age, 95% confidence interval [CI]: 0.6-0.9, P = .003) and at urban practices (RR 2.3, 95% CI: 1.1-5.0, P = .028), and less frequently in practices with computer reminders for ordering screening tests (RR 0.6, 95% CI: 0.3-0.9, P = .024). In multivariate analyses, the rate of ultrasound ordering did not change after adoption of density notification laws (RR 0.7, 95% CI: 0.3-2.0, P = .57). CONCLUSION: The rate of screening ultrasound ordering remains low over time. There was no observed association between adoption of state-level density reporting laws and overall changes in ultrasound ordering.

RESUMO

OBJECTIVES: Evaluation of the knowledge of couples concerning the prenatal screening ultrasound in order to improve information. METHODS: This prospective, observational and comparative study was carried out in three maternal centers: a level III maternity, a level II private maternity, and a private gynecologist's office where prenatal screening ultrasounds were performed between the first of March 2018 and the 31th of April 2018. A questionnaire was given to all pregnant women coming to consult for a prenatal screening ultrasound. It included items on maternal characteristics, pregnancy characteristics, and screening ultrasound. RESULTS: One hundred and sixty-nine women answered the questionnaire. On the 138 participants who had consulted in the level III maternity, 42 % expected them to study fetal well-being, 38 % growth, and 13 % malformation. Forty-six percent attested to have received a request for consent, as well as information about these ultrasounds. The same is true for the 120 spouses in thelevel III maternity where only 7 % expected a malformation search to be carried out. The number of participants in the type II private maternity and the private gynecologist's office was insufficient. CONCLUSION: The information given and received, and the knowledge of couples in this level III maternity about the prenatal screening ultrasound seem to be insufficient. It is therefore important to inform the pregnant women and their spouse by giving consent before the first ultrasound and by a verbal message, simple and clear about what the professional is looking for in order to reduce this discrepancy, and thus prepare the couple in case of announcement of an anomaly.

RESUMO

In women with dense breasts (heterogeneously or extremely dense), adding screening ultrasound to mammography increases detection of node-negative invasive breast cancer. Similar incremental cancer detection rates averaging 2.1-2.7 per 1000 have been observed for physician- and technologist-performed handheld ultrasound (HHUS) and automated ultrasound (AUS). Adding screening ultrasound (US) for women with dense breasts significantly reduces interval cancer rates. Training is critical before interpreting examinations for both modalities, and a learning curve to achieve optimal performance has been observed. On average, about 3% of women will be recommended for biopsy on the prevalence round because of screening US, with a wide range of 2%-30% malignancy rates for suspicious findings seen only on US. Breast Imaging Reporting and Data System 3 lesions identified only on screening HHUS can be safely followed at 1 year rather than 6 months. Computer-aided detection and diagnosis software can augment performance of AUS and HHUS; ongoing research on machine learning and deep learning algorithms will likely improve outcomes and workflow with screening US.

RESUMO

Screening ultrasound (US) is increasingly used as a supplement to mammography in women with dense breasts, and more than 80% of cancers detected by US alone are 1cm or smaller. An adaptive computer-aided diagnosis (CAD) system based on tumor size was proposed to classify breast tumors detected at screening US images using quantitative morphological and textural features. In the present study, a database containing 156 tumors (78 benign and 78 malignant) was separated into two subsets of different tumor sizes (<1cm and ⩾1cm) to explore the improvement in the performance of the CAD system. After adaptation, the accuracies, sensitivities, specificities and Az values of the CAD for the entire database increased from 73.1% (114/156), 73.1% (57/78), 73.1% (57/78), and 0.790 to 81.4% (127/156), 83.3% (65/78), 79.5% (62/78), and 0.852, respectively. In the data subset of tumors larger than 1cm, the performance improved from 66.2% (51/77), 68.3% (28/41), 63.9% (23/36), and 0.703 to 81.8% (63/77), 85.4% (35/41), 77.8% (28/36), and 0.855, respectively. The proposed CAD system can be helpful to classify breast tumors detected at screening US.

RESUMO

Aneurysmal dilation of the aorta is a clinically silent disease that often presents first with a catastrophic event. As a result, several clinician societies and organizations have recommended screening to detect aneurysms before they rupture. Although screening may reduce mortality, the implementation of screening has been poor. Cardiologists are uniquely positioned to improve this gap as they handle patients with typical risk factors for aneurysmal diseases of the aorta and can endorse and implement screening in a high-risk population. The following article attempts to concisely give a navigational tool to the cardiovascular specialist for her/his role in the diagnosis and management of thoracic and abdominal aortic aneurysms, citing evidence as well as stating opinions on how to improve outcomes in this unique patient population.

RESUMO

Sonography is an attractive supplement to mammography in breast cancer screening because it is relatively inexpensive, requires no contrast-medium injection, is well tolerated by patients, and is widely available for equipment as compared with MRI. Sonography has been especially valuable for women with mammographically dense breast because it has consistently been able to detect a substantial number of cancers at an early stage. Despite these findings, breast sonography has known limitations as a screening tool; operator-dependence, the shortage of skilled operators, the inability to detect microcalcifications, and substantially higher false-positive rates than mammography. Further study of screening sonography is still ongoing and is expected to help establish the role of screening sonography.

RESUMO

То assess the prevalence and pattern of thyroid disease in Moscow, a mild iodine-deficiency area, the authors examined a random sample of 1103 individuals (1004 females and 99 males) during 14 months. The examinees' age ranged from 17 to 80 years; the mean age was 36.7±14.05; median was 37 years. The survey involved a physical examination with thyroid palpation, brief history data collection, and thyroid ultrasound study on a "Mysono"portable apparatus with a 7.5-MHz linear transducer, operating on a real-time basis. Among the examinees the echographic signs of these or those thyroid changes were found in 36% of cases. The most common abnormalities were focal thyroid tissue changes, whose prevalence was 12.4%. Thyroid nodular masses were encountered at a slightly less frequency (10.5%). Of them, nodular and multinodular goiter accounted for 6 and 4.5%, respectively. The third group of changes is presented by a diffuse decrease in thyroid tissue echogenicity (9%). Diffuse goiter was less frequently identified; its frequency was 5%. A minor proportion (0.1%) of the examinees had a history of operations for this or that thyroid disease.
