Dermoscopy increases the sensitivity of the diagnosis of melanoma, leading to its early identification and increasing the chances of cure.

To describe the clinical and dermoscopic characteristics of superficial spreading melanomas, and to detect the differences between in situ and invasive 1-mm thick melanomas.

This was a cross-sectional study in which dermoscopic images of 58 melanomas, grouped according to their thickness, were evaluated.

24 in situ melanomas were evaluated, 28 invasive melanomas with Breslow ≤ 1 mm (0.50 ± 0.22 mm) and six with Breslow > 1 mm (2.35 ± 2.02 mm). In situ melanomas were smaller than invasive melanomas. The most commonly found dermoscopic criteria were asymmetry (84.5%), three or more colors (81.0%), and atypical network (79.3%). A non-specific pattern was more common in in situ melanomas (p = 0.028) and atypical network in invasive melanomas with Breslow 1 mm presented inverted network (p = 0.018).

The sample was selected by convenience, since it was necessary to have a preoperative photo of the tumor, which may have led to the loss of clinically less significant lesions, as well as those highly suggestive of melanoma.

Melanomas in early stages showed a more frequent nonspecific pattern and atypical network, while invasive melanomas showed a multicomponent pattern, three or more colors, and an inverted network.

The histopathology is addressed regarding its indications, main findings and limitations, as a complementary diagnostic method largely used by dermatologists. Electron microscopy is briefly reviewed, along with its contribution to the accumulated knowledge on HPV, as well as the relevance of research in using this technology for future advances in diagnosis and treatment. Molecular information about the virus is continuously increasing, and the practical applications of HPV serology, molecular identification and genotyping are discussed. Vaccines are a valuable tool in primary HPV infection prevention and are now available in many countries; their composition, indications, and adverse effects are revisited. Local and systemic treatment options are reviewed and off-label prescriptions are discussed. Finally, health education focusing on HPV infection as a sexually transmitted infection of worldwide relevance and the many barriers to improve primary and secondary prevention are addressed.

The negative impact of stress on the mental health of perinatal women is well-established. Prior research using data from the Pregnancy Risk Assessment Monitoring System (PRAMS) confirms three distinct stress domains financial, relationship, and trauma. In 2013, an item assessing perceived racial discrimination was added to the Iowa PRAMS. Using the first phase of available data, we examine whether perceived racial discrimination represents an independent stress domain and assess its association with postpartum depressed mood.

A principal component analysis of the Iowa PRAMS data (2013-2015 N=2,805) evaluated stress and perceived racial discrimination. Logistic regression examined the effect of racial discrimination on postpartum depressed mood.

In Iowa, 4.4% of respondents perceived racial discrimination, with higher rates among non-Hispanic Black women and Hispanic women. The principal component analysis identified five stress domains financial, relational, traumatic, emotional, and displacement. Perceived racial discrimination did not load onto any of these domains, suggesting that it represents an independent stress component. Logistic regression indicated that those who experienced perceived racial discrimination were twice as likely to have experienced depressed mood.

Racism, in the form of perceived racial discrimination among pregnant women, is a unique domain of stress that is significantly associated with an increased risk for depressed postpartum mood. Decreasing discrimination’s effects on perinatal mental health could begin with ensuring respectful and compassionate health care during pregnancy and the postpartum period.

The review provides an overview of psychiatric illnesses as both contributors and sequelae of 4 major injury patterns self-inflicted wrist lacerations, self-amputation, upper-extremity fractures, and burns. The authors develop a multidisciplinary model for upper-extremity surgeons to care for patients with psychiatric disorders, with an overview of capacity assessment, optimal psychiatric comanagement, and collaboration with allied health professionals.

As a digital presence rapidly becomes more important for educators, Twitter continues to emerge as a compelling source for publishing educational content. The social media platform has also evolved into a popular source for medical and radiology education. We examined how Twitter is used in the radiology sphere and introduce ways of optimizing Twitter for radiology education.

We evaluated our Twitter account (@ctisus), dedicated to radiology education and based in the Russell H. BAY-985 manufacturer Morgan Department of Radiology and Radiological Science at Johns Hopkins Hospital, to learn from our users and evaluate how best to leverage the platform for radiology education. We culled analytics for all 1584 tweets we released from July to December 2019 and divided them into seven educational categories for analysis case images; illustrations and infographics; slide images (taken from educational PowerPoints); case question videos; scroll-through videos; links to educational content on our website (lectures, quizzes, etc.) or online databases; and news links, including published journal articles and general medical and/or radiology news.
