Cutaneous drug reactions are the most common type of adverse drug reaction. These reactions, ranging from simple pruritic eruptions to potentially life-threatening events, are a significant cause of iatrogenic morbidity and mortality. ⋯ Nevertheless, despite being a problem that is global in scope, government and health care agencies worldwide have yet to find a consensus on either diagnostic criteria or therapy for this disorder. Here, we provide the internist and emergency room physician with a brief review the SJS literature and summarize the latest recommended interventions with the hope of improving early recognition of this disease and prevention of permanent sequelae and mortality that frequently complicate SJS.

Calcium (Ca(2+)) and phosphate (P(i)) are essential to many vital physiological processes. Consequently the maintenance of Ca(2+) and P(i) homeostasis is essential to a healthy existence. This occurs through the concerted action of intestinal, renal, and skeletal regulatory mechanisms. ⋯ Novel regulatory mechanisms and their implications were introduced for the antiaging hormone klotho and fibroblast growth factor member 23 (FGF23). Importantly, transgenic mouse models, exhibiting disturbances in Ca(2+) and P(i) balance, have been of great value in the elucidation of klotho and FGF23 functioning. This review highlights the current knowledge and ongoing research into Ca(2+) and P(i) homeostasis, emphasizing findings from several relevant knockout mouse models.

Genital human papillomavirus (HPV) infection and HPV-associated cervical and other anogenital cancers are significant public health problems. HPV 16 and HPV 18 are responsible for approximately 70% of all invasive cervical cancers worldwide. The first prophylactic HPV virus-like particle (VLP) vaccine against HPV types 6/11/16/18 was licensed in 2006 for girls and women aged 9-26 years. ⋯ Therefore, it is important to understand that the population impact of the vaccines will be much lower than vaccinating naive populations. Implementing HPV vaccine is a great opportunity but also a great challenge. However, mandatory HPV vaccination may raise many questions, and more answers are needed.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the only proven curative therapy for chronic myeloid leukemia (CML), but lack of human leukocyte antigen (HLA)-matched sibling or unrelated donors has restricted its application. Recently, we developed an effective method for haploidentical allo-HSCT achieving comparable outcomes to HLA-identical transplantation. ⋯ For patients lacking an HLA-identical related donor, haploidentical relatives are alternative HSCT donors.

Calcium sensitizers are a new group of inotropic drugs. Levosimendan is the only calcium sensitizer in clinical use in Europe. Its mechanism of action includes both calcium sensitization of contractile proteins and the opening of adenosine triphosphate (ATP)-dependent potassium channels as mechanism of vasodilation. ⋯ These trials did not require filling pressures to be measured. The two trials showed that levosimendan improves the symptoms of heart failure, but does not improve survival. The results raise the question whether a 24-hour levosimendan infusion can be used without invasive hemodynamic monitoring.
