Opsoclonus in Pediatric Patients: Differential Diagnosis and a Practical Approach to Evaluation

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Opsoclonus is an ocular dyskinesia characterized by involuntary, arrhythmic, multidirectional saccades. In pediatrics, opsoclonus is most commonly attributed to the rare neuroinflammatory disorder opsoclonus‐myoclonus‐ataxia syndrome (OMAS), typically considered a paraneoplastic syndrome associated with neural crest tumors. However, opsoclonus

A practical difference from the normal approach to evaluate natural killer (NK) cells and NK cell neoplasms by flow cytometry

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract Natural killer (NK) cell neoplasms span indolent to highly aggressive entities, and flow cytometric immunophenotyping is central to their detection and classification. However, distinguishing reactive from neoplastic NK cell expansions can be challenging because NK cells lack somatically recombined antigen receptors, and reactive states may ...

Subset‐specific and tissue‐specific expression of NK‐cell markers and killer immunoglobulin‐like receptors: Implications for NK‐cell clonality assessment

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract Accurate immunophenotypic evaluation of natural killer (NK)‐cell neoplasms is challenging because NK‐cells lack somatically rearranged antigen receptors, are comprised of phenotypically distinct subsets, and exhibit tissue‐specific subset distribution. We developed a flow cytometry (FC) panel for NK‐cell immunophenotypic analysis and clonality

Diagnostic Usefulness of Cell Block Samples in Fluid Overload‐Associated Large B‐Cell Lymphoma

Diagnostic Cytopathology, EarlyView.
ABSTRACT Fluid overload‐associated B‐cell lymphoma (FO‐LBCL) is a B‐cell neoplasm that presents as serous effusions without detectable tumor masses and Kaposi sarcoma‐associated herpesvirus (KSHV)/human herpesvirus 8 (HHV8) infection. Here, we report a case of an 81‐year‐old female patient with FO‐LBCL (Stage IVA) who presented with pericardial and ...

Pattern of Failure in Nasopharyngeal Carcinoma After Radiotherapy in a Low‐Incidence Population: A DAHANCA Study

Head &Neck, EarlyView.
ABSTRACT Background Nasopharyngeal carcinoma (NPC) is uncommon in many populations. Most existing clinical evidence comes from endemic areas, where Epstein–Barr virus (EBV)‐associated subtypes predominate. We analyzed patterns of failure in a population‐based cohort from Denmark, a low‐incidence setting.

Latent Epstein-Barr virus infection and the germinal center reaction [PDF]

, 2007
Epstein-Barr virus (EBV) is a γ-herpes virus which preferentially infects human B lymphocytes. It is highly adapted to persist in B cells since it encodes for proteins which mimic several cellular proteins playing an important role in B cell ...

Pretreatment EBV‐DNA/TLG‐Based Risk Stratification Is Associated With Survival Outcomes in Nonmetastatic Nasopharyngeal Carcinoma: An Exploratory Study

International Journal of Cancer, EarlyView.
ABSTRACT Whether combining pretreatment plasma Epstein–Barr virus DNA (EBV‐DNA) with 18F‐FDG PET/CT‐derived total lesion glycolysis (TLG) improves prognostic stratification in nonmetastatic nasopharyngeal carcinoma (NPC) is unclear, particularly in nonendemic populations.
