Herpes Simplex Virus-2 Esophagitis in a Young Immunocompetent Adult

Herpes simplex esophagitis (HSE) is commonly identified in immunosuppressed patients. It is rare among immunocompetent patients and almost all of the reported cases are due to HSV-1 infection. HSV-2 esophagitis is extremely rare. We report the case of a young immunocompetent male who presented with dysphagia, odynophagia, and epigastric pain. Endoscopy showed multitudes of white nummular lesions in the distal esophagus initially suspected to be candida esophagitis. However, classic histopathological findings of multinucleated giant cells with eosinophilic intranuclear inclusions and positive HSV-2 IgM confirmed the diagnosis of HSV-2 esophagitis. The patient rapidly responded to acyclovir treatment. Although HSV-2 is predominantly associated with genital herpes, it can cause infections in other parts of the body previously attributed to only HSV-1 infection

Multidisciplinary strategies to treat severe hypoglycemia in hospitalized patients with diabetes mellitus reduce inpatient mortality rate: Experience from an academic community hospital.

ObjectiveSevere hypoglycemia (blood glucose Research design and methodsWe performed retrospective review of pre- and post- intervention study to quantify severe hypoglycemia in patients admitted in the general internal medicine wards with primary or secondary diagnosis of diabetes mellitus based on ICD-9 and ICD-10 codes. We implemented multidisciplinary interventions including standardization of treatment, education of in-patient medical teams and physician notification and feedback immediately after severe hypoglycemia. The endpoints were the comparative analysis of incidence of severe hypoglycemia, in-patient mortality rate, 30-day mortality rate, 30-day readmission rate, recovery time from hypoglycemia, time to next glucose measurements, use of standardized treatment and physician notification rate pre-and post-intervention.ResultsThe incidence of severe hypoglycemia per patient with diabetes was reduced from 9.6% (233/2416) to 5.6% (202/3607) (pConclusionsOur study shows that multidisciplinary strategies improves the process of early detection and management of severe hypoglycemia and reduce incidence and in-patient mortality rate

Advances in using MRI probes and sensors for in vivo cell tracking as applied to regenerative medicine

The field of molecular and cellular imaging allows molecules and cells to be visualized in vivo non-invasively. It has uses not only as a research tool but in clinical settings as well, for example in monitoring cell-based regenerative therapies, in which cells are transplanted to replace degenerating or damaged tissues, or to restore a physiological function. The success of such cell-based therapies depends on several critical issues, including the route and accuracy of cell transplantation, the fate of cells after transplantation, and the interaction of engrafted cells with the host microenvironment. To assess these issues, it is necessary to monitor transplanted cells non-invasively in real-time. Magnetic resonance imaging (MRI) is a tool uniquely suited to this task, given its ability to image deep inside tissue with high temporal resolution and sensitivity. Extraordinary efforts have recently been made to improve cellular MRI as applied to regenerative medicine, by developing more advanced contrast agents for use as probes and sensors. These advances enable the non-invasive monitoring of cell fate and, more recently, that of the different cellular functions of living cells, such as their enzymatic activity and gene expression, as well as their time point of cell death. We present here a review of recent advancements in the development of these probes and sensors, and of their functioning, applications and limitations
