The clinical performance of Invader technology and SurePath when detecting the presence of high-risk HPV cervical infection.

Background: Testing for high-risk genotypes of the human papillomavirus (HR HPV) has been fully integrated into the management algorithms for the prevention of cervical cancer. The literature is limited with regard to the evaluation of the clinical performance of laboratory-developed tests (LDT) utilizing Invader V2.0 assay (ThirdWave/Hologic, Madison, WI, USA) for the detection of HR HPV.

A comparison of two methods to determine the presence of high-risk HPV cervical infections.

Clinical tests for human papillomavirus (HPV) DNA require clinical validation before being offered for use by laboratories. To determine the clinical viability of a laboratory-developed test using the Invader HPV reagents (Third Wave Technologies, Madison, WI), a retrospective study was designed using 213 patient cervical cytologic samples. The results of the Invader assay were directly compared with the results obtained using the Hybrid Capture 2 High-Risk HPV assay (Digene, Gaithersburg, MD).

Clinical manifestations of hemoglobin Chico at high altitude.

Hemoglobin Chico is a rare hemoglobinopathy characterized by low oxygen affinity and a right-shifted oxygen dissociation curve. Detailed clinical evaluations of affected individuals have not been previously reported. We therefore report on the clinical features of Hemoglobin Chico in a Latino male living at high altitude, who desired to participate in school sports.

Peripheral T-cell lymphoma with extensive dendritic cell network mimicking follicular dendritic cell tumor: a case report with pathologic, immunophenotypic, and molecular findings.

Peripheral T-cell lymphoma (PTCL) with a nodular pattern of growth is uncommon and may be misdiagnosed initially as a B-cell lymphoma or reactive process. We report a case of a rapidly growing PTCL with a distinctly nodular pattern in an axillary lymph node from an 89-year-old man. Immunohistochemical stains for CD21, CD23, and CD35 highlighted an extensive dendritic cell network that imparted the nodular appearance and, in addition, was associated intimately with the neoplastic cells.

Nonsecretory variant of immunoproliferative small intestinal disease: a case report with pathologic, immunophenotypic, and molecular findings.

We report a case of the nonsecretory variant of immunoproliferative small intestinal disease involving the distal small bowel and the mesenteric and retroperitoneal lymph nodes in a 19-year-old woman from Mexico. This variant extranodal marginal zone B-cell lymphoma appeared similar in the different sites of involvement, with more interspersed large cells and greater plasmacytic differentiation present in intestinal specimens. Characteristic lymphoepithelial lesions and follicular colonization were seen in intestinal and lymph node sections, respectively.
