Risk of coronary artery disease in patients with idiopathic inflammatory myopathies: A systematic review and meta-analysis of observational studies

Objectives

To investigate the risk of coronary artery disease in patients with idiopathic inflammatory myopathies (IIM).

Methods

We conducted a systematic review and meta-analysis of observational studies that reported odds ratios, relative risks, hazard ratios, or standardized incidence ratios comparing the risk of coronary artery disease in patients with IIM versus non-IIM participants. We searched published studies indexed in MEDLINE, EMBASE, and the Cochrane database from inception to December 2013 using the terms “coronary artery disease” OR “coronary heart disease” OR “myocardial infarction” OR “atherosclerosis” combined with the terms “dermatomyositis” OR “polymyositis” OR “Idiopathic inflammatory myopathy.” Pooled risk ratio and 95% confidence interval were calculated using a random-effect, generic inverse variance method.

Result

Overall, four studies were identified and included for data analysis. The pooled risk ratio of CAD in patients with IIM was 2.24 (95% CI: 1.02–4.92). The statistical heterogeneity of this meta-analysis was high with an I² of 97%.

Conclusion

Our study demonstrated a statistically significant increased risk of CAD among patients with IIM.     

A rare case of ecthyma gangrenosum associated with methicillin-resistant Staphylococcus aureus infection

Ecthyma gangrenosum (EG) is a well-recognized dermatological condition caused by gram-negative bacillary infection, particularly Pseudomonas aeruginosa. Association with gram-positive cocci is very rarely reported in the literature. To the best of our knowledge, we describe the third case of EG caused by methicillin-resistant Staphylococcus aureus in a patient with AIDS who presented with multiple typical necrotic lesions.     

Lagenidium sp. Ocular Infection Mimicking Ocular Pythiosis

This is a report of a Lagenidium sp. in a Thai patient who was diagnosed with severe keratitis that was unresponsive to antibacterial and antifungal drugs. Examination of a corneal biopsy specimen confirmed the presence of aseptate hyphae. The internal transcribed spacer DNA sequence of the strain isolated showed 97% identity with Lagenidium giganteum and other Lagenidium species.     

Trend of human rabies prophylaxis in developing countries: Toward optimal rabies immunization

Rabies is a fatal infectious disease. Because prevention is the key management for rabies, many vaccination regimens have been developed and used worldwide. The aims for developing rabies vaccination regimens include decreasing the number and amount of dosages, decreasing the duration and the number of clinical visits, and reducing cost. Interestingly, some intradermal (ID) regimens have proved to be as effective as the standard intramuscular (IM) regimens, and have been increasingly used in developing countries because they are less expensive. In this article, we reviewed rabies vaccines based on results obtained from clinical trials and international treatment guidelines for post-exposure prophylaxis, pre-exposure prophylaxis for the high risk group, and booster vaccination.     

Pulmonary blastomycosis: a new endemic area in New York state

We describe three cases of pulmonary blastomycosis in patients from central New York State (NYS). Two of these cases occurred in 2012, and in patients who resided in the same county. Moreover, two of these cases manifested with acute respiratory distress syndrome and survived. Interestingly, one of the two received corticosteroids and was extubated within 1 week. To the best of our knowledge, these are the first cases of human blastomycosis to be reported from NYS and we propose that corticosteroids administration might reduce hospitalisation time and ventilator‐associated complications, even though it is not currently recommended in standard treatment.
