Delta and Omicron SARS-CoV-2 pneumonia: Comparison of clinical and radiological features.

Background: Computed tomography (CT) is a critical tool for the diagnosis of pneumonia caused by SARS-CoV-2. The Delta and Omicron variants show distinct clinical features, but the radiological differences between pneumonia caused by these variants have not been extensively studied in patients with oxygen-dependent pneumonia.

Objective: To compare the radiological and clinical features of pneumonia in patients hospitalized with oxygen-dependent SARS-CoV-2 infection caused by the Delta and Omicron variants.

Sentinel Lymph Node Detection in Early-Stage Oral Squamous Cell Carcinoma Using Magnetic Resonance Lymphography: A Pilot Study.

To assess the efficacy of magnetic resonance (MR) lymphography with gadobutrol contrast for sentinel lymph node (SLN) mapping in early-stage oral squamous cell carcinoma (OSCC). This pilot study compared the identification of SLNs by MR lymphography using a gadolinium-based contrast agent (gadobutrol) to conventional [Tc]Tc-nanocolloid lymphoscintigraphy (including single-photon emission computed tomography/computed tomography (SPECT/CT)) in 10 early-stage OSCC patients undergoing SLN biopsy. The patients initially underwent conventional lymphoscintigraphy following the peritumoral administration of indocyanine green [Tc]Tc-nanocolloid (120 megabecquerel; ~0.

Evaluation of the 10 %-rule in sentinel lymph node biopsy for clinically node-negative oral squamous cell carcinoma.

Background: Sentinel lymph node biopsy (SLNB) has proven to reliably stage the clinically negative neck in early-stage oral squamous cell carcinoma (OSCC). The 10%-rule, used to define sentinel lymph nodes (SLN) intraoperatively, states that an SLN is defined by gamma counts that are at least 10% of the hottest harvested lymph node (LN). However, this intraoperative rule has not yet been adequately evaluated for early-stage OSCC.

Efficacy and safety of co-trimoxazole in device-related bone and joint infections: a CRIOGO multicentre case-control study.

Objectives: Co-trimoxazole could be an alternative antibiotic to treat device-related bone and joint infection (BJI) but there are few published data about its efficacy and safety in this complex scenario to treat infection. The objective was to compare the outcome of patients with device-related BJI treated with an antibiotic regimen including co-trimoxazole versus a regimen without co-trimoxazole.

Methods: This multicentre case-control study included consecutive adult patients diagnosed with device-related BJI.

Derivation and validation of a risk-stratification model for patients with probable or proven COVID-19 in EDs: the revised HOME-CoV score.

Background: The HOME-CoV (Hospitalisation or Outpatient ManagEment of patients with SARS-CoV-2 infection) score is a validated list of uniquely clinical criteria indicating which patients with probable or proven COVID-19 can be treated at home. The aim of this study was to optimise the score to improve its ability to discriminate between patients who do and do not need admission.

Methods: A revised HOME-CoV score was derived using data from a previous prospective multicentre study which evaluated the original Home-CoV score.
