Infection
-
To study the role of the neutrophil:lymphocyte ratio (NLR) and monocyte:lymphocyte ratio (MLR) in discriminating between different patient groups hospitalized for fever due to infection and those without infection. ⋯ NLR is a more useful diagnostic tool to identify patients with septicemia than other more commonly used diagnostic blood tests. NLR and MLR may be useful in the diagnosis of bacterial infection among patients hospitalized for fever.

Review Case Reports
Acute human herpes virus 7 (HHV-7) encephalitis in an immunocompetent adult patient: a case report and review of literature.
We report a case of an acute HHV-7 encephalitis involving the nucleus of the VI cranial nerve in an immunocompetent host. The patient was an adult male admitted to our Clinic with headache, diplopia, fever, nausea, vertigo, asthenia and general malaise. PCR for viral and bacterial genomes was run on both serum and cerebral spinal fluid (CSF) after performing lumbar puncture, resulting positive only for HHV-7 DNA on CSF. ⋯ Empirical therapy with Acyclovir and Dexamethasone was started at the time of admission and was continued after the microbiology results. After three days of therapy diplopia, fever and other previous clinical manifestations improved and the patient recovered normal sight. Our case report contributes to a better understanding of the presentation, diagnosis and treatment of HHV-7 encephalitis in immunocompetent patients due to reactivation in adult age.

Physicians frequently rely on the systemic inflammatory response syndrome (SIRS) criteria to detect bloodstream infections (BSIs). We evaluated the diagnostic performance of procalcitonin (PCT) in detecting BSI in patients with and without SIRS. ⋯ The performance of PCT for the diagnosis of BSI was not affected by SIRS status. Only PCT was independently associated with BSI, while the SIRS criterion and serum lactate were not. A low PCT value may be used to identify patients at a low risk for having BSI in both settings. An elevated PCT value even in a SIRS negative patient should prompt a careful search for BSI.

Observational Study
Three months of weekly rifapentine plus isoniazid for latent tuberculosis treatment in solid organ transplant candidates.
Isoniazid daily for 9 months is the recommended regimen for latent tuberculosis infection (LTBI) in solid organ transplant (SOT) candidates, but its use is controversial, due to reports of hepatotoxicity and low treatment completion rates. A 12-week course of once weekly directly observed therapy (DOT) with isoniazid plus rifapentine (3HP) is a new LTBI treatment regimen. Tolerability and safety data of 3HP LTBI treatment in SOT candidates are limited. ⋯ Directly observed 3HP LTBI treatment was not associated with hepatotoxicity, even in patients with higher MELD scores. Further studies are needed to confirm the safety and efficacy of this LTBI treatment regimen in the SOT population.

The purpose of this study was to evaluate the diagnostic value of 18F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT scan) and magnetic resonance imaging (MRI) in diagnosing spondylodiscitis and its complications, such as epidural and paraspinal abscesses. ⋯ As compared to MRI, 18F-FDG-PET/CT has superior diagnostic value for detecting early spondylodiscitis. After 2 weeks both techniques perform similarly.
