The use of systemic corticosteroids (SC) for the treatment of psoriasis is not recommended according to textbooks and guidelines. In clinical practise, however, many physicians frequently prescribe SC for patients with psoriasis. To determine the magnitude of SC prescription for outpatients with psoriasis in Korea and identify factors associated with the use of SC, we used the 2010-2014 nationwide claims data of the Health Insurance Review and Assessment Service of Korea. In frequency analysis for the full scale of prescribed SC, oral methylprednisolone was the most frequently prescribed SC, followed by dexamethasone and betamethasone injections...

Incretin-based medications (glucagon-like peptide-1 [GLP-1] receptor agonists and inhibitors of dipeptidyl peptidase-4 [DPP-4] are glucose-lowering drugs approved and introduced after 2006 (1). Although both classes of drugs appeared to be relatively safe based on results from clinical trials and standard animal toxicology studies, epidemiological data (2, 3) and histological findings (4) in genetically modified rodents exposed to such agents have raised concern that pancreatitis and pancreatic cancer may be long-term risks associated with this therapy...

Endometriosis has significant implications on patient health and well-being, particularly when it comes to pelvic pain and infertility. However, the true epidemiologic state of the disease has remained elusive. Many of the foundational studies characterize surgically confirmed endometriosis in highly selected patient populations. It has been hypothesized that the prevalence of endometriosis is approximately 10% (Vigano et al, Best Practices and Research in Clinical OB/GYN, 2004, 18(2):177-200) of reproductive aged women and may reach rates of 30-50% in symptomatic women...

Mycobacterium tuberculosis (M. tuberculosis) genotyping has dramatically improved the understanding of the epidemiology of tuberculosis (TB). In this study, 187 M. tuberculosis isolates from Xinjiang Uygur Autonomous Region (Xinjiang) and Gansu province in China were genotyped using large sequence polymorphisms (LSPs) and variable number tandem repeats (VNTR). Ten isolates, which represent major nodes of VNTR-based minimum spanning tree, were selected and subsequently subjected to multi-locus sequence analyses (MLSA) that include 82 genes...

In hemophilia A, the most severe complication of factor VIII (FVIII) replacement therapy involves the formation of FVIII neutralizing antibodies, also known as inhibitors, in 25-30% of patients. This adverse event is associated with a significant increase in morbidity and economic burden, thus highlighting the need to identify methods to limit FVIII immunogenicity. Inhibitor development is regulated by a complex balance of genetic factors, such as FVIII genotype, and environmental variables, such as coexistent inflammation...

REVIEW
Sandra Blome, Christoph Staubach, Julia Henke, Jolene Carlson, Martin Beer
Classical swine fever (CSF) remains one of the most important transboundary viral diseases of swine worldwide. The causative agent is CSF virus, a small, enveloped RNA virus of the genus Pestivirus. Based on partial sequences, three genotypes can be distinguished that do not, however, directly correlate with virulence. Depending on both virus and host factors, a wide range of clinical syndromes can be observed and thus, laboratory confirmation is mandatory. To this means, both direct and indirect methods are utilized with an increasing degree of commercialization...

Epidemiological studies have demonstrated an association between low serum albumin levels and both coronary artery disease (CAD) and mortality. However, the long-term clinical impact of low serum albumin level in patients with CAD undergoing percutaneous coronary intervention (PCI) has not yet been fully investigated. We studied 2860 all-comer patients with CAD who underwent their first PCI and had data available for pre-procedural serum albumin between 2000 and 2011. Patients were assigned to tertiles based on pre-procedural albumin levels...
