Cytologic and Histological Features Distinguishing Myxoid Meningioma From Chordoid Meningioma: A Case Report

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Meningiomas are the most common primary brain tumors worldwide and are classified into 15 subtypes in the 5th edition of the WHO classification. Myxoid meningioma, characterized by the presence of a mucinous matrix within the tumor, is a rare metaplastic meningioma subtype classified as WHO grade 1.

Nonlinear Filters for Hidden Markov Models of Regime Change with Fast Mean-Reverting States

open access: yes, 2012
We consider filtering for a hidden Markov model that evolves with multiple time scales in the hidden states. In particular, we consider the case where one of the states is a scaled Ornstein-Uhlenbeck process with fast reversion to a shifting-mean that is

Steroidogenic Factor 1 (SF1) Immunohistochemical Stain Is Sensitive and Specific for the Cytopathologic Identification of Intrapancreatic Ectopic Splenic Tissue

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Background Accessory spleens result from failure of splenic fusion during development and are occasionally located in the pancreatic tail, radiographically appearing as solid or solid/cystic lesions. Fine needle aspiration (FNA) easily identifies accessory spleens in most samples based on architecture and using CD8 to highlight splenic ...

Why not "do simple things in a simple way": Use of the Pap test as the first step in screening genetic stability for human cultured stem cell therapy? [PDF]

open access: yes, 2011
The aim of this study was to analyze adipose tissue-derived mesenchymal stem cells (AT-MSCs) using the Pap test as a first screening step to evaluate genetic stability.

Phagocytic Mesothelial Cells in Pericardial Effusion Following Allogeneic Peripheral Blood Stem Cell Transplantation for Chronic Active Epstein–Barr Virus Infection: A Distinctive Cytomorphological and Immunocytochemical Case Study

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Phagocytic activity of mesothelial cells is a rare phenomenon requiring careful differentiation from histiocytic hemophagocytosis to ensure appropriate patient management, as these phenomena could exhibit distinct clinical implications. In this study, we report a case of phagocytic mesothelial cells found in pericardial effusion that developed

Pancreatic Adenocarcinoma: Diagnosis by Ultrasound‐Guided Fine‐Needle Aspiration—Cyto‐Histological Correlation and Experience at a Multidisciplinary Tertiary Reference Center

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Background Pancreatic adenocarcinoma (PDAC) is characterized by its poor prognosis. Cytology is essential for diagnostic confirmation and ancillary studies. The endoscopic ultrasound (EUS) set a precedent, facilitating cytological sampling through fine‐needle aspiration (FNA), with a sensitivity of 93% and a specificity of 95%.

Problems in Papanicolaou Classification

open access: yesJournal of UOEH, 1993
There are several reasons why Papanicolaou classification should not be used for the interpretation of cytologic findings. First, many different classification criteria are sometimes used for a single pathologic condition. Second, inflammatory change or hormonal evaluation are not included in the system.

Illumination strategies for intensity-only imaging [PDF]

open access: yes, 2014
We propose a new strategy for narrow band, active array imaging of localized scat- terers when only the intensities are recorded and measured at the array. We consider a homogeneous medium so that wave propagation is fully coherent.

Scattering of magnetic solitons in two dimensions

open access: yes, 2001
Solitons which have the form of a vortex-antivortex pair have recently been found in the Landau-Lifshitz equation which is the standard model for the ferromagnet.
