Blasts with folded nuclei: A histopathologic finding in myeloid leukemia cutis with NPM1 and FLT3 mutations.

Leukemia cutis is a term used to describe cutaneous manifestations of leukemic infiltration of the skin and portends a poor prognosis. Cutaneous involvement by hematopoietic/lymphoid tumors can occur before, concurrently, or after the initial diagnosis. Early involvement of dermatologists and timely biopsies play a crucial role in achieving a prompt diagnosis. Prior reports of acute myeloid leukemia have revealed a strong association between the cup-like nuclear morphology observed in bone marrow specimens and concurrent mutations of NPM1 and FLT3-ITD. In cutaneous tissue sections of leukemia cutis, folded or indented nuclei may represent the "cup-like" counterpart previously described in bone marrow specimens. Recognizing this morphological feature could aid in identifying this molecular subtype of leukemia cutis. In this study, we present a case of leukemia cutis in a 63-year-old female with AML and NPM1 and FLT3-ITD mutations, demonstrating scattered indented/folded nuclei.

Content analysis of breast milk substitutes marketing on Chinese e-commerce platforms.

China has the largest and fastest-growing breast milk substitutes (BMSs) market and a disproportionately low exclusive breastfeeding rate. Many BMS manufacturers have established Chinese e-commerce stores. This marketing is of concern as it is likely to undermine breastfeeding. This study aimed to identify: (1) the marketing themes and strategies used to promote BMSs on the Chinese BMSs e-commerce websites; (2) if and how digital BMSs marketing may deviate from the World Health Organization Code of Marketing of Breast Milk Substitutes (the Code) recommendations. Content analysis was conducted on the flagship websites of 10 BMSs companies on the Chinese e-commerce platform "TMall" in July 2019. The main landing page (n = 10) of the flagship TMall website and the product description page (n = 113) of all individual formulas (Stages 1-3) within each company's TMall website were examined. The content was analysed and coded using an iterative thematic analysis approach. Emphasis on Premiumization and Science & Nutrition was the most commonly used marketing approaches. A total of 27.4% of the product description pages sampled used images of infants (<12 months), 33.6% made favourable comparisons of BMSs to breast milk, and only 34.5% included probreastfeeding statements. Marketing strategies were often inconsistent with the Code, and companies used "creative" ways to target mothers, often circumventing the Code recommendations. Unsubstantiated information was commonplace and of concern, because the e-commerce platform provided easy opportunities for bulk purchases. National regulatory actions are urgently needed to monitor online BMS marketing and the undermining of breastfeeding in China.

Shake it off: A curious case of rigors.

Heparin-induced Anaphylactoid reactions are rare systemic reactions to heparin exposure. Although the exact pathogenesis of the reaction is unclear, in vivo platelet activation from inflammation may play a role. The reaction involves anti-platelet factor 4, a common factor also noted to be involved in heparin-induced thrombocytopenia (HIT). Like HIT, prompt identification of the reaction, immediate discontinuation of heparin, and supportive care are the mainstays of treatment to avoid severe and potentially fatal outcomes. Previous cases have described heparin-induced anaphylactoid reactions in the setting of heparin-induced thrombocytopenia. However, we will present a case of an isolated heparin-induced anaphylactoid reaction without HIT.
