Metaxalone-induced Immune Hemolytic Anemia.

Drug-induced immune hemolytic anemia (DIIHA) is a relatively uncommon cause of anemia, and its diagnosis can be challenging. Although beta-lactam antimicrobial agents are often associated with DIIHA, any medication can potentially cause it. We describe a patient presenting with yellow skin discoloration and orange-colored urine after starting metaxalone for treatment of lumbosacral sprain. Laboratory studies were consistent with warm hemolytic anemia. Symptoms improved remarkably after discontinuation of metaxalone, coupled with initiation of glucocorticoids and rituximab.

Skin lesion in a patient after hematopoietic stem cell transplant.

We present a case of a 61-year-old Caucasian woman who was hospitalized with fever on day 176 after a matched unrelated stem cell transplant for acute myelogenous leukemia. She developed hemorrhagic bullae on the skin of her right thigh, and both blood cultures and skin biopsy confirmed Fusarium proliferatum. Despite antifungal therapy, her condition worsened and she died while on comfort-only measures.

The Human Papillomavirus Vaccine: Current Perspective and Future Role in Prevention and Treatment of Anal Intraepithelial Neoplasia and Anal Cancer.

UNLABELLED: The incidences of human papillomavirus (HPV)-related anal cancer and its precursor lesion, anal intraepithelial neoplasia, are rising in the U.S. and globally. Five-year survival rates with current modalities of treatment for anal cancer are generally favorable for localized and regional disease. For metastatic disease, the relative survival rate is poor. Major contributing factors for the increase in anal cancer incidence include increasing receptive anal intercourse (hetero- and homosexual), increasing HPV infections, and longer life expectancy of treated people who are seropositive for human immunodeficiency virus. Because treatment outcomes with systemic therapy in patients with advanced disease are so poor, prevention may be the best approach for reducing disease burden. The association of a major causative agent with anal cancer provides an excellent opportunity for prevention and treatment. The advent of the HPV vaccine for anal cancer prevention and treatment is a significant milestone and has the potential to greatly impact these cancers. The data regarding potential use of the HPV vaccine in anal cancer prevention and treatment are reviewed. IMPLICATIONS FOR PRACTICE: The incidences of human papillomavirus (HPV)-related anal cancer and its precursor lesion, anal intraepithelial neoplasia, are on the rise in the U.S. and globally. Based on recent studies, the HPV vaccine is approved for prevention of the infection and development of HPV-related anal cancer. In addition, several small studies have shown that the vaccine may be useful as adjuvant therapy for anal cancer. There is a need for public health strategies aimed at education of both patients and practitioners to improve the use of the vaccine for prevention of HPV-related anal cancer. The development of a therapeutic vaccine is a work in progress.
