Background And Purpose: Polyneuropathies associated with monoclonal gammopathy of undetermined significance (MGUS) encompass a group of phenotypically and immunologically heterogeneous neuropathies. While the best characterized is that associated with anti-myelin glycoprotein (MAG) antibodies, there are phenotypical and immunological neuropathy variants that still lack a clear classification. We analyzed a significant number of patients, in order to better evaluate the distribution of neuropathy phenotypes and to look for some common characteristics.

Methods: Clinical, neurophysiological, and laboratory data from 87 consecutive MGUS patients with peripheral neuropathy were analyzed and compared among patient groups with different MGUS classes and autoantibody reactivity.

Results: Anti-MAG neuropathy cases account for the most homogeneous group with regard to clinical and neurophysiological findings. Patients with anti-gangliosides or sulfatide (GS) antibodies, despite a marked phenotype heterogeneity, still share several common features, including a younger age at diagnosis, a more severe disease, and a prompt and sustained response to both immunoglobulin and rituximab therapies, mostly requiring chronic administration of immune treatment.

Conclusions: Although heterogeneous, MGUS-associated, anti-GS antibody positive neuropathies have important similar features possibly resulting from a similar biological background.

Anal cytology and high-risk human papilloma virus testing in atypical squamous categories: Value of concurrent testing in management of high-risk population.

Authors:
Adela Cimic Anjali Saqi

Diagn Cytopathol 2021 Apr 19. Epub 2021 Apr 19.

Department of Pathology and Cell Biology, Columbia University Medical Center, New York, New York, USA.

Anal squamous cell carcinoma is relatively rare, but its incidence and mortality have been increasing worldwide. While anal cytology is a sensitive cancer screening modality, its specificity is low, and data for concurrent high-risk human papilloma virus (HR-HPV) testing are limited. At our institution, anal cancer screening consists of combined anal cytology and high-risk human papilloma virus (HR-HPV) testing on all specimens. Read More

Reflections on the unexpected laboratory finding of hemorheological alterations observed in some haematological disorders.

Authors:
Gregorio Caimi Rosalia Lo Presti Melania Carlisi

Microvasc Res 2021 Apr 13:104171. Epub 2021 Apr 13.

Department of Health Promotion and Child Care, Internal Medicine and Medical Specialties, Università degli Studi di Palermo, Palermo, Italy. Electronic address:

Hyperviscosity syndrome is a clinical condition characterized by the slowing of blood flow through the vessels and it may be associated with several diseases. The nosographic classification of primary hyperviscosity conditions (Wells classification 1970) divided the primary hyperviscosity syndromes in polycythaemic, sclerocytemic and sieric. Recent and personal laboratory observations have highlighted an unexpected behaviour of the erythrocyte deformability observed in some haematological disorders such as polycythemia vera, multiple myeloma and monoclonal gammopathy of undetermined significance.

Department of Obstetrics and Gynecology, Second Hospital of Shanxi Medical University, Taiyuan, Shanxi 030001, China.

In this prospective, population-based study, we evaluated the utility of high-risk human papillomavirus (HR-HPV) genotyping for triaging women with atypical squamous cells of undetermined significance (ASC-US) in the Chinese rural area. A total of 40,000 women were recruited from rural areas of Shanxi Province, China, between June 2014 and December 2014. Women with Pap results of ASC-US underwent HPV genotyping, colposcopy and histopathological examination. Read More
