Hydroxyurea-induced genital ulcers and erosions: Two case reports.

J Tissue Viability 2021 Jun 6. Epub 2021 Jun 6.

Harvard Medical School, Boston, MA, USA; Department of Dermatology, Brigham and Women's Hospital, Boston, MA, USA. Electronic address:

Hydroxyurea is a chemotherapeutic agent used for myeloproliferative disorders and sickle cell anemia that is well known to cause painful mucocutaneous ulcers, typically involving the legs or mouth. However, genital ulcerations due to hydroxyurea therapy are a rare, and likely underrecognized, adverse effect with only a few cases reported in the literature to date. Ulcers of the lower legs caused by hydroxyurea are associated with a diagnostic delay, and this is likely exacerbated in cases of genital ulceration due to a lack of awareness. Read More

Rapid identification of mutations caused by fast neutron bombardment in Medicago truncatula.

Plant Methods 2021 Jun 16;17(1):62. Epub 2021 Jun 16.

Guangdong Key Laboratory for Innovative Development and Utilization of Forest Plant Germplasm, College of Forestry and Landscape Architecture, South China Agricultural University, Guangzhou, 510642, Guangdong, China.

Background: Fast neutron bombardment (FNB) is a very effective approach for mutagenesis and has been widely used in generating mutant libraries in many plant species. The main type of mutations of FNB mutants are deletions of DNA fragments ranging from few base pairs to several hundred kilobases, thus usually leading to the null mutation of genes. Despite its efficiency in mutagenesis, identification of the mutation sites is still challenging in many species. Read More
