Effusion cytology of EBV-associated lymphoma: a concise review.

Epstein-Barr virus (EBV)-associated lymphomas can, on rare occasions, involve body cavities, making effusion cytology an important diagnostic tool. This mini-review explores the spectrum of EBV-related lymphomas that may be detected in serous fluids, including EBV-positive nodal T/NK-cell lymphoma (EBV + nT/NKCL), extranodal NK/T-cell lymphoma, primary effusion lymphoma, EBV-positive diffuse large B-cell lymphoma, and classic Hodgkin lymphoma. We present an index case of EBV + nT/NKCL with lymphomatous pleural effusion and discuss the cytologic features, differential diagnoses, and role of anc

NMUS provides a dynamic, real time assessment of anatomy which can alter both diagnostic and management pathways in peripheral nerve disorders. This review describes the current and future techniques used in NMUS and details the applications and developments in the diagnosis and monitoring of compressive, hereditary, immune-mediated and axonal peripheral nerve disorders, and motor neuron diseases. Technological advances have

Small molecule modulators of chromatin remodeling: from neurodevelopment to neurodegeneration.

The dynamic changes in chromatin conformation alter the organization and structure of the genome and further regulate gene transcription. Basically, the chromatin structure is controlled by reversible, enzyme-catalyzed covalent modifications to chromatin components and by noncovalent ATP-dependent modifications via chromatin remodeling complexes, including switch/sucrose nonfermentable (SWI/SNF), inositol-requiring 80 (INO80), imitation switch (ISWI) and chromodomain-helicase DNA-binding protein (CHD) complexes. Recent studies have shown that chromatin remodeling is essential in different stag

Disruption of the microenvironmental ecosystem in subchondral bone marrow lesions: Roles in osteoarthritis pathophysiology, pain and progression.

This narrative review explores the role of subchondral bone in the pathophysiology of osteoarthritis (OA), emphasizing the biomechanical and biochemical contributions that it makes to disease progression. A fresh perspective is presented by the authors in the form of a novel hypothesis that implicates mechano-inflammatory disruption of the bone marrow (BM) microenvironmental ecosystem (BM niche), unresolved inflammation, and fibrosis as key drivers of OA pathogenesis and pain. BMLs, detectable via magnetic resonance imaging (MRI), serve as dynamic imaging biomarkers that correlate with pain se

The Neuro-Bone Axis in Metastatic Progression: Innervation, Neuro-Immune-Osteoclast Crosstalk, and Therapeutic Opportunities.

Bone metastases represent a major cause of morbidity in advanced cancers, yet the neural regulation of metastatic growth within bone remains largely unexplored. The skeletal system is richly innervated by sensory and sympathetic nerve fibers that influence bone remodeling, hematopoiesis, and immune surveillance. Emerging evidence suggests that disseminated tumor cells exploit these neural circuits to create a growth-permissive microenvironment. Tumor-secreted neurotrophic factors can induce nerve sprouting, while sympathetic activation via β-adrenergic receptors promotes osteoclastogenesis, im

State of oral mucosa as an additional symptom in the course of primary amyloidosis and multiple myeloma disease.

Multiple myeloma (myeloma multiplex (MM)) is a malignant non-Hodgkin's lymphoma derived from B cell. Its essence is a malignant clone of plasma cells synthesizing growth of monoclonal immunoglobulin, which infiltrate the bone marrow, destroy the bone structure, and prevent the proper production of blood cells components. The paper presents a case of 62-year-old patient who developed symptoms in addition to neurological and haematological changes in the oral mucosa in the course of multiple myeloma. The treatment resulted in partial improvement. The authors wish to draw attention not only to no

Effect of recombinant human nerve growth factor treatment on corneal nerve regeneration in patients with neurotrophic keratopathy.

IntroductionNeurotrophic Keratopathy (NK) is a neurodegenerative corneal disease that results in diminished corneal sensation. Previous studies have found that Cenegermin 0.002%, a recombinant human nerve growth factor (rhNGF), improves corneal epithelial healing in stage 2 and 3 NK patients. However, rhNGF effect on corneal sensation and nerve regeneration has not been well established. Thus, this study aims to analyze the effect of rhNGF on corneal nerve regeneration using in vivo confocal microscopy (IVCM) and on corneal sensitivity in NK patients.MethodsThis is a retrospective, longitudina

Rare Diseases of the Orbit.

This article provides an overview of rare orbital diseases. Congenital malformations, inflammatory diseases, benign and malignant neoplasias are described. Although it represents a relatively small area of the body the orbit contains multiple different tissues. Therefore, a great variety of diseases can be found within the orbital space. That is the reason, why both the completeness and the level of detail in the description of particular diseases must be somewhat limited. Nevertheless, clinical manifestations, important aspects of diagnosis, treatment strategies, and, when specific data are a

Efficacy and Safety of Botulinum Toxin A and Pulsed Radiofrequency on Postherpetic Neuralgia: A Randomized Clinical Trial.

This study evaluated the effectiveness and safety of botulinum toxin type A (BoNT-A) and pulsed radiofrequency (RF) in the clinical treatment of postherpetic neuralgia (PHN). A total of 100 patients with PHN were randomly divided into two groups (n = 50 per group): RF group and BoNT-A group. Based on conventional drug treatment, patients were treated with either a single nerve root pulsed radiofrequency therapy or a single local subcutaneous injection of BoNT-A in the lesion area. All the patients were followed up for 24 weeks on pain scores, sleep quality, anxiety, and depression scores, etc.
