Hepatosplenic Abscess From in Poorly Controlled Diabetic.

Invasive infection and pyogenic liver abscess in patients with underlying diabetes mellitus has been well described over the past 3 decades, predominantly in the Southeast Asian population, especially in Taiwan and Korea. has now become the most common causative pathogen of pyogenic liver abscess in Asian countries. This shift from to may also be increasingly occurring in the United States of America and European countries.

Graves' Disease in a Patient With Human Immunodeficiency Virus Infection as an Immune Reconstitution Inflammatory Syndrome.

The use of highly active antiretroviral therapy (HAART) in the management and treatment of human immunodeficiency virus type 1 (HIV-1) has dramatically changed the course of the disease and improved overall survival. HAART results in significant decrease in viral load and enhancement of CD4 cells and gradual restoration of the immune system. However, a subset of patients may experience a paradoxical worsening after the initiation of HAART due to a heightened and dysregulated immune response.

Invasive Pneumococcal Disease in a Patient With COVID-19: A Case Report.

The spread of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has resulted in a global health pandemic and caused profound morbidity and mortality worldwide. The virus is known to cause severe hypoxemic respiratory failure and has been associated with extrapulmonary manifestations and end-organ dysfunction in the setting of extensive inflammatory response. Recently, the association between COVID-19 and pneumococcal pneumonia co-infection or superinfections has gained increasing interest.

Unraveling the Mystery of Gray Zone Lymphoma in Human Immunodeficiency Virus-Seropositive Patients: Two Cases.

Gray zone lymphoma (GZL) is an uncommon neoplasm with intermediate features of both classic Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL). It was identified in the World Health Organization (WHO) classification as its own neoplasm in 2008. Patients infected with human immunodeficiency virus (HIV) have been rarely diagnosed with this type of lymphoma and treatment strategies for this subset of patients is not well described.

Isolated Pulmonary Valve Fungal Endocarditis with Candida parapsilosis: Management Considerations of a Rare Case.

Pulmonary valve infections without the involvement of other valves account for only 1.5- 2% of all infective endocarditis cases. Isolated pulmonary valve endocarditis due to fungus is extremely rare.

Atazanavir-Associated Crystalline Nephropathy.

Crystalline nephropathy can occur following treatment with multiple therapeutic agents. We describe a human immunodeficiency virus (HIV)-infected patient treated for 2 years with combination antiretroviral therapy including atazanavir (ATV). Kidney biopsy revealed a crystalline nephropathy associated with diffuse chronic and granulomatous interstitial inflammation.

Irreproducible and uninterpretable Polymyxin B MICs for Enterobacter cloacae and Enterobacter aerogenes.

Carbapenem-resistant Enterobacter species are emerging nosocomial pathogens. As with most multidrug-resistant Gram-negative pathogens, the polymyxins are often the only therapeutic option. In this study involving clinical isolates of E.

Activity of polymyxin B and the novel polymyxin analogue CB-182,804 against contemporary Gram-negative pathogens in New York City.

Multidrug-resistant Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa have become common in many regions, often requiring therapy with colistin or polymyxin B. An increase in resistance to these agents would render many infections untreatable. We tested the activity of polymyxin B and the novel polymyxin analogue CB-182,804 against over 5,000 recent Gram-negative clinical isolates from New York City, a region with a high prevalence of multiresistant strains.

Accuracy of carbapenem nonsusceptibility for identification of KPC-possessing Enterobacteriaceae by use of the revised CLSI breakpoints.

Using the updated 2010 CLSI carbapenem breakpoints for the Enterobacteriaceae, nonsusceptibility to ertapenem and imipenem predicted the presence of bla(KPC) poorly, especially among Escherichia coli and Enterobacter species. In regions where KPC-producing bacteria are endemic, testing for nonsusceptibility to meropenem may provide improved accuracy in identifying these isolates.
