Cognitive impairment in Behçet's disease patients without overt neurological involvement

We investigated the prevalence of cognitive impairment in patients with Behc¸et’s disease (BD) without overt neurological involvement. The influence of disease duration, disease activity, prednisone dosage, and anxiety and depression levels was evaluated. Twenty-six consecutive BD outpatients and 26 healthy controls matched for age, education and sex completed a comprehensive neuropsychological battery including tests of memory, visuospatial and constructional abilities, language, attention and psychomotor speed, non-verbal reasoning and executive functioning. The Hamilton scales for anxiety and depression were administered. Disease activity was assessed using the Behc¸et’s Disease Current …

Rituximab plus chemotherapy provides no clinical benefit in a peripheral T-cell lymphoma not otherwise specified with aberrant expression of CD20 and CD79a. A case report and review of the literature

Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is the most common entity of mature T-cell neoplasms. PTCL-NOS generally has an aggressive behavior and is often refractory to standard therapy. Only a few cases of PTCL with aberrant expression of B-cell antigens have been reported so far. This phenotypic aberrancy may lead to misdiagnosis as B-cell non-Hodgkin lymphomas and eventual inappropriate patient management, whereas in an accurately diagnosed PTCL, the presence of CD20 may appear as an appealing therapeutic target. In this setting, response to anti-CD20 monoclonal antibody in combination with chemotherapy has been poorly explored. We describe the case of a 59-year-old …

Transcriptional analysis distinguishes breast implant-associated anaplastic large cell lymphoma from other peripheral T-cell lymphomas

Breast implant-associated anaplastic large cell lymphoma is a new provisional entity in the revised World Health Organization classification of lymphoid malignancies, the pathogenesis and cell of origin of which are still unknown. We performed gene expression profiling of microdissected breast implant-associated anaplastic large cell lymphoma samples and compared their transcriptional profiles with those previously obtained from normal T-cells and other peripheral T-cell lymphomas and validated expression of selected markers by immunohistochemistry. Our results indicate that most breast implant-associated anaplastic large cell lymphomas exhibit an activated CD4+ memory T-cell phenotype, whi…

Spatial transcriptome of a germinal center plasmablastic burst hints at MYD88/CD79B mutants-enriched diffuse large B-cell lymphomas

The GC reaction results in the selection of B cells acquiring effector Ig secreting ability by progressing toward plasmablastic differentiation. This transition is associated with exclusion from the GC microenvironment. The aberrant expansion of plasmablastic elements within the GC fringes configures an atypical condition, the biological characteristics of which have not been defined yet. We investigated the in situ immunophenotypical and transcriptional characteristics of a nonclonal germinotropic expansion of plasmablastic elements (GEx) occurring in the tonsil of a young patient. Compared to neighboring GC and perifollicular regions, the GEx showed a distinctive signature featuring key r…

Lack of association between angiotensin converting enzyme polymorphism and sporadic Alzheimer's disease

Epidemiological and pathogenetic evidences suggest a strong association between vascular risk factors and sporadic Alzheimer's disease (sAD). In agreement with the vascular hypothesis of AD, the role of various candidate genes for atherosclerosis has been investigated, leading to conflicting results. In order to clarify the significance of angiotensin-converting enzyme (ACE) gene insertion (I)/deletion (D) polymorphism in a group of patients with sAD, we conducted a case-control study including 149 cases and 149 age and sex matched controls. All subjects were genotyped for ACE and Apolipoprotein E (APOE). There were no significant differences in ACE genotype or allele frequencies between ca…

RNA Sequencing of Primary Cutaneous and Breast-Implant Associated Anaplastic Large Cell Lymphomas Reveals Infrequent Fusion Transcripts and Upregulation of PI3K/AKT Signaling via Neurotrophin Pathway Genes

Simple Summary Cutaneous and breast implant-associated anaplastic large-cell lymphomas are usually localized neoplasms with an indolent clinical course compared to systemic ALCL. However comparative analyses of the molecular features of these two entities have not yet been reported. We performed targeted RNA sequencing, which revealed that fusion transcripts, although infrequent, might represent additional pathogenetic events in both diseases. We also found that these entities display upregulation of the PI3K/Akt pathway and show enrichment in genes of the neurotrophin signaling pathway. These findings advance our knowledge regarding the pathobiology of cALCL and BI-ALCL and point to additi…

Restless legs syndrome in a patient with multifocal motor neuropathy

Restless legs syndrome (RLS) has been frequently reported in association with peripheral neuropathy, and it is especially frequent in some forms of polyneuropathy with preferential involvement of small sensory fibers. Here, we describe a patient with multifocal motor neuropathy, who developed RLS during the course of the disease. Our findings support the notion that RLS may develop in the context of immune-mediated neuropathies and it should be specifically investigated even in those patients with preferentially or exclusive motor involvement.

Guillain-Barré Syndrome

Background: Guillain–Barré syndrome is a rare disorder in which our body’s immune system attacks nerves determining weakness and tingling of extremities as first symptoms. It can also be associated to respiratory failure and require mechanical ventilation during hospitalization (up to 30% of patients). Nowadays patient’s hyper-reactive immune responses benefits from immunotherapies such as intravenous immunoglobulin (IVIg), therapeutic plasma exchange (TPE) and new biological drugs. Case Report: We report our experience with the case of a 64-year-old woman who presented a symmetric progressive flaccid paralysis after a week of mild cold symptoms. The respiratory and neurological symptoms wo…

No association between Glu298Asp endothelial nitric oxide synthase polymorphism and Italian sporadic Alzheimer's disease.

A great amount of evidence suggests that neuroinflammation may be a major pathogenetic mechanism in the pathophysiology of sporadic Alzheimer's Disease (sAD). Recently, polymorphisms in the endothelial nitric oxide synthase (NOS3) gene have been associated to late onset Alzheimer's Disease in a British population. However, other groups failed to replicate this finding in Asiatic and Caucasian populations. We conducted a case-control study including a clinically well-defined group of 149 sAD patients and 149 age and sex matched controls to test the association between NOS3 Glu298Asp polymorphism and sAD in an ethnically homogenous Italian population. All subjects were genotyped at NOS3 and a…
