Objectives: To increase awareness of potential diagnostic test interference associated with alemtuzumab, which is a therapeutic immunoglobulin G1 κ monoclonal antibody used in hematologic malignancies, autoimmune diseases, and transplant-related disorders. Methods: Bone marrow and blood from patients with T-cell prolymphocytic leukemia treated with alemtuzumab were evaluated by flow cytometry. Healthy donor blood was analyzed with or without in vitro treatment with alemtuzumab for comparison...

Objectives: Bone marrow biopsies are essential for evaluating patients with suspected or confirmed hematopoietic disorders or malignancies, but little is known about how biopsy needle type affects biopsy length and/or quality. We sought to compare bone marrow biopsy quality in specimens obtained with two different needles. Methods: A retrospective analysis was performed on bone marrow specimens obtained with manual single-bevel (n = 114) or triple-bevel (n = 166) needles...

Objectives: To determine the accuracy of Fungitell, a β-d-glucan (BDG) test, for the diagnosis of invasive fungal infection (IFI) among cancer patients. Methods: For this meta-analysis, MEDLINE and EMBASE were searched for references related to BDG testing. Study quality was evaluated using QUADAS-2. Statistical analysis was performed using Stata 14. Results: We screened 12,426 references and identified 189 studies for full-text review. Nineteen studies were included in the final meta-analysis...

Objectives: We evaluated performance and measurement uncertainty of the newly released ARCHITECT 25-OH vitamin D 5P02 assay (Abbott Diagnostics, Abbott Park, IL). Methods: In total, 300 samples were used to compare the results from ELECSYS Vitamin D Total (Roche Diagnostics, Mannheim, Germany) and ADVIA Centaur Vitamin D Total (Siemens, Tarrytown, NY). To quantify the measurement uncertainty, 25 samples and four levels of standard reference material (SRM) were measured using isotope dilution-liquid chromatography-tandem mass spectrometry according to international guidelines...

Objectives: Indications for cholecystectomy have changed dramatically over the past three decades. Cystoisospora belli has been reported in cholecystectomy specimens of immunocompetent patients. The present study was designed to determine the prevalence and clinical association of C belli in the gallbladder. Methods: The study included retrospective review of cholecystectomy specimens (n = 401) removed for various indications, and a prospective cohort of cholecystectomy specimens (n = 22) entirely submitted for histologic evaluation...

Objectives: To develop age- and sex-specific RBC reference intervals using the National Health and Nutrition Examination Survey (NHANES) 1999 to 2012, a large nationally representative, population-based, cross-sectional database (n = 44,328). Methods: Comprehensive medical data were used to define a "healthy" population. Reference intervals for RBC count, hemoglobin, hematocrit, mean cell hemoglobin, mean cell hemoglobin concentration, mean cell volume, and red cell distribution width were computed using piecewise regression, an evidence-based statistical procedure that identifies breakpoints...

Objectives: Renal biopsy is the gold standard for the diagnosis of both native and allograft renal diseases. We studied the impact of tissue procurement at bedside (TPB) omission on the adequacy of renal biopsies. Methods: We compared 120 renal biopsies collected during 2015 using TPB with 111 renal biopsies collected during 2016 when TPB was discontinued. Adequacy criteria were applied as follows: by light microscopy, 10 glomeruli and two arteries for allograft biopsies and seven glomeruli for native biopsies...

Objectives: To evaluate the clinical performance of novel detection kits for 14 high-risk human papillomavirus (hrHPV) types with the BD Onclarity HPV Assay (Onclarity; Becton Dickinson, Sparks, MD). Methods: Two cervical specimens from 144 women were obtained and placed in BD SurePath Collection Vials. The first specimen was used for cervical cytology and digene HC2 High-Risk HPV DNA Test (HC2; Qiagen, Germantown, MD), and the second specimen was used for Onclarity and Roche Cobas 4800 HPV (Cobas; Roche Molecular Systems, Pleasanton, CA)...

Objectives: Underfilling of blood culture bottles decreases the sensitivity of the culture. We attempt to increase average blood culture fill volumes (ABCFVs) through an educational program. Methods: Partnerships were established with four hospital units (surgical intensive care unit [SICU], medical intensive care unit [MICU], medical intermediate care unit [MIMCU], and hematology and oncology unit [HEME/ONC]). ABCFVs were continuously tracked and communicated to each unit monthly...

Objectives: A CBC with leukocyte differential (CBC-DIFF) is a frequently ordered emergency department (ED) test. The DIFF component often does not add to clinical decision making. Our objective was to evaluate the impact of a performance improvement project on CBC ordering. Methods: ED orders for CBC-DIFF were identified through the laboratory information system. Two interventions were evaluated: an educational intervention regarding CBC-DIFF uses and a reprioritization of ED CBC-DIFF and CBC in the electronic medical record (EMR) orders...

Neda Kalhor, Cesar A Moran
Objectives: Twelve cases of thymomas with prominent alveolar-like growth pattern are presented. Methods: The 12 cases were identified during a review of more than 350 cases of thymomas. Results: The patients were five women and seven men between the ages of 48 and 69 years (mean, 58.5 years). Clinically, all patients presented with nonspecific symptoms. Grossly the tumors varied in size from 3.5 to 5 cm in greatest diameter. Histologically, all tumors showed a predominant alveolar-like growth pattern without a significant lymphocytic component...

Objectives: Knowledge of transfusion medicine by medical students is limited. Transfusion medicine physicians developed, implemented, and evaluated a half-day elective on transfusion medicine for fourth-year medical students. Methods: The course included a didactic lecture with integrated audience response questions and role-playing, as well as a "Jeopardy"-style game to review the material. The same 10-question knowledge quiz was administered before and after the elective...

Objectives: To examine the fidelity of ink color identification using light microscopy (LM), telemicroscopy (TM), and virtual microscopy (VM). Methods: Twenty H&E-stained frozen section slides, prepared after tissue inking with five stain combinations, were assessed by three pathologists using LM, TM, and VM. TM was performed using Mikroscan D2 slide scanner/LiveQ software with various objectives. VM was performed using Mikroscan D2 scanner/Qumulus software, specimens digitized at20×...

Objectives: We report four new cases of natural killer-cell enteropathy (NKCE) and similar lymphoproliferative disorders (LPDs), as well as review the literature concerning indolent natural killer (NK)-cell LPDs of the gastrointestinal tract. Methods: Pathologic and clinical data were obtained from institutional/referral records. Results: Patient 1 (45-year-old man) had anemia; a small intestinal lesion was endoscopically biopsied. Patient 2 (65-year-old woman) had biliary colic, treated with cholecystectomy...

Objectives: As pathologists and laboratorians, we can enhance patient care by promoting the appropriate ordering of diagnostic tests. Our goal was to improve the ordering of BCR-ABL1 tests by using the EPIDEM model of quality improvement. Methods: We applied the EPIDEM model, which emphasizes understanding local context, culture, and resources, to explore inappropriate BCR-ABL1 ordering, promote and implement a new reflexive testing strategy in-house, document and evaluate effectiveness, and make stepwise modifications...

Objectives: Bethesda category III (atypia of undetermined significance/follicular lesion of undetermined significance) includes sparsely cellular specimens with nuclear atypia (3N) and/or architectural atypia (3A). This study investigates whether the two types of atypia have different rates of malignancy (ROMs). Methods: Cytologic and histologic diagnoses of resected thyroid nodules were recorded. ROM was calculated for all Bethesda categories and for 3N and 3A subcategories...
