Methicillin-Sensitive Staphylococcus aureus-Associated Leukocytoclastic Vasculitis: A Case Report and Literature Review.

The association of s with vasculitis remains relatively rare and poorly understood. In this report, we present a case of Methicillin-sensitive (MSSA)-associated leukocytoclastic vasculitis (LCV) following a surgical site infection, adding to the limited body of knowledge on this intriguing clinical entity. A 52-year-old male with a medical history significant for type 2 diabetes mellitus, hypertension, hyperlipidemia, and coronary artery disease presented with progressively worsening generalized petechial rash and migratory joint pains with associated joint swelling.

Identification of potential endometriosis biomarkers in peritoneal fluid and blood plasma via shotgun lipidomics.

Endometriosis is a recurrent and benign gynecological disorder, defined by the ectopic presence of endometrium. About 10% of reproductive-aged women suffer from endometriosis. There are no non-invasive or minimally invasive tests available in clinical practice to accurately diagnose endometriosis today.

A Comparison of Tissue Spray and Lipid Extract Direct Injection Electrospray Ionization Mass Spectrometry for the Differentiation of Eutopic and Ectopic Endometrial Tissues.

Recent research revealed that tissue spray mass spectrometry enables rapid molecular profiling of biological tissues, which is of great importance for the search of disease biomarkers as well as for online surgery control. However, the payback for the high speed of analysis in tissue spray analysis is the generally lower chemical sensitivity compared with the traditional approach based on the offline chemical extraction and electrospray ionization mass spectrometry detection. In this study, high resolution mass spectrometry analysis of endometrium tissues of different localizations obtained using direct tissue spray mass spectrometry in positive ion mode is compared with the results of electrospray ionization analysis of lipid extracts.

Direct Mass Spectrometry Differentiation of Ectopic and Eutopic Endometrium in Patients with Endometriosis.

Study Objective: To introduce a method for the rapid assessment of endometriotic tissues using direct mass spectrometry (MS)-based lipidomics.

Design: A prospective observational cohort study (Canadian Task Force classification II2).

Setting: Department of Operative Gynecology of the Research Centre for Obstetrics, Gynecology and Perinatology.

Endometriosis foci differentiation by rapid lipid profiling using tissue spray ionization and high resolution mass spectrometry.

Obtaining fast screening information on molecular composition of a tissue sample is of great importance for a disease biomarkers search and for online surgery control. In this study, high resolution mass spectrometry analysis of eutopic and ectopic endometrium tissues (90 samples) is done using direct tissue spray mass spectrometry in both positive and negative ion modes. The most abundant peaks in the both ion modes are those corresponding to lipids.
