Spinal Cord Compression As the Initial Manifestation of Relapsed Acute Myeloid Leukemia: A Case Report and Literature Review of a Rare Presentation.

Myeloid sarcoma (MS) is a solid mass of myeloid blasts outside the bone marrow (BM). Most cases occur in the setting of intramedullary acute myeloid leukemia (AML), but it can also present in the absence of overt BM disease, as a presentation of newly diagnosed or relapsed AML, or as a progression of myeloproliferative neoplasms or myelodysplastic syndromes. There are a few reports of spinal cord compression due to MS, and there is no consensus regarding its management. Here, we present a case of relapsed AML in the form of MS resulting in spinal cord compression and provide a comprehensive li

Are We Ready For "Triplet" Therapy in Higher-Risk MDS?

Higher-risk Myelodysplastic Syndromes/Neoplasms (MDS) represent an ongoing therapeutic challenge, with few effective therapies, many of which may have limited use in this older patient population often with considerations around comorbidities. Outside of transplant, azacitidine and decitabine remain the only disease-modifying therapies, and are palliative in nature. Recent interest has grown in extending combination chemotherapies used to treat acute myeloid leukemia (AML) to patients with MDS, including novel combination chemotherapy "doublets" and "triplets." In this review, we discuss consi

Renal Involvement in Mixed Cryoglobulinemic Vasculitis: Current Perspectives.

Cryoglobulinemia is a rare disorder characterized by the presence of abnormal proteins (cryoglobulins) in the blood that precipitate at low temperatures. It presents with a wide clinical spectrum, from mild symptoms to severe, life-threatening disease. In mixed cryoglobulinemia (MC), vascular damage results from immune complexes-typically monoclonal IgM with rheumatoid factor activity and polyclonal IgG (Type II), or polyclonal/oligoclonal IgM and IgG (Type III). These complexes can obstruct small blood vessels, leading to ischemia and leukocytoclastic vasculitis. Renal involvement occurs in a

Sclerosing diseases of the skin.

Sclerosing skin diseases comprise a group of distinct dermatological conditions characterized by fibrotic changes that may severely impair patients' quality of life. These conditions often present with cutaneous manifestations and, in some cases, may extend to extracutaneous tissues, potentially resulting in significant morbidity and mortality. This review explores the current understanding of the four most prevalent sclerosing skin diseases - localized scleroderma (morphea), systemic sclerosis (SSc), scleromyxedema, and scleredema adultorum of Buschke - as well as sclerotic conditions induced

… The infiltrating cells include lymphocytes, eosinophils, plasma cells and histiocytes, which are located within the collagen bundles, around blood vessels and at the periphery of adnexal structures. 7 In the later stages, as inflammation subsides, the lesion becomes avascular, with thickened vessel walls …

Annexin A1 affects tumor metastasis through epithelial-mesenchymal transition: a narrative review.

Background and objectiveAnnexin A1 (annexin I, ANXA1), the first discovered member of the annexin superfamily, plays important roles in tumor development, invasion, metastasis, apoptosis and drug resistance based on tumor type-specific patterns of expression. The acquisition of the epithelial-mesenchymal transition (EMT) characteristics is an essential mechanism of metastasis because they increase the mobility and invasiveness of cancer cells. Cancer invasion and metastasis remain major health problems worldwide. Elucidating the role and mechanism of ANXA1 in the occurrence of EMT will help ad

An Insight into Anticancer Effect of Propolis and Its Constituents: A Review of Molecular Mechanisms.

Propolis is a natural compound collected by honeybees from different parts of plants. Honeybees produce a sticky component besides honey by mixing the tree resin and other botanical sources with saliva called propolis or bee glue. Propolis was traditionally used as a wound healing substance, cosmetic, medicine, and many other conditions. Till now, there is no definite curable treatment for most cancers and chemotherapeutic drugs and drugs used for targeted therapies have serious side effects. According to a recent research, natural products are becoming increasingly essential in cancer prevent

Adaptation of the Charlson Comorbidity Index for Register-Based Research in Sweden.

PurposeComorbidity indices are often used to measure comorbidities in register-based research. We aimed to adapt the Charlson comorbidity index (CCI) to a Swedish setting.MethodsFour versions of the CCI were compared and evaluated by disease-specific experts.ResultsWe created a cohesive coding system for CCI to 1) harmonize the content between different international classification of disease codes (ICD-7,8,9,10), 2) delete incorrect codes, 3) enhance the distinction between mild, moderate or severe disease (and between diabetes with and without end-organ damage), 4) minimize duplication of co

Hypothesis: are neoplastic macrophages/microglia present in glioblastoma multiforme?

Most malignant brain tumours contain various numbers of cells with characteristics of activated or dysmorphic macrophages/microglia. These cells are generally considered part of the tumour stroma and are often described as TAM (tumour-associated macrophages). These types of cells are thought to either enhance or inhibit brain tumour progression. Recent evidence indicates that neoplastic cells with macrophage characteristics are found in numerous metastatic cancers of non-CNS (central nervous system) origin. Evidence is presented here suggesting that subpopulations of cells within human gliomas

Rituximab-Induced Interstitial Lung Disease: A Possible Underestimated Complication-A Systematic Review.

Background: Rituximab, a monoclonal antibody targeting CD20, has revolutionized the management of B-cell lymphoproliferative disorders and some immune conditions, significantly improving disease control and patient survival. Beyond its indisputable therapeutic benefits, rituximab can cause serious pulmonary adverse events, particularly interstitial lung disease (R-ILD). Diagnosing R-ILD is challenging due to nonspecific clinical and imagistic features, and its true incidence is possibly underestimated. Methods: We conducted a systematic review to synthesize current evidence on R-ILD, focusing

Common Neurologic Diseases in Geriatric Dogs.

The increase in the canine geriatric population means that veterinarians are more often confronted with diseases that are more prevalent in patients in this age group. As in other organ systems, degenerative, neoplastic, and vascular diseases are the most prevalent neurologic disorders in older dogs. A neurological disease in an older dog poses a challenge for the clinician due to the presence of concomitant diseases and age-related changes that make it difficult to interpret the neurological examination. In addition, given the age of the patients, some owners do not allow advanced imaging tes

Hypophosphatemia in cancer patients.

Dysregulation of phosphorus homeostasis resulting in hypophosphatemia is common in cancer patients and can result in serious complications and impact outcomes. Several factors, including critical illness, nutritional status, cancer type and therapy, influence the development of hypophosphatemia. Hypophosphatemia can develop as a result of phosphaturic mesenchymal tumors or as a paraneoplastic phenomenon. The clinical presentation for hypophosphatemia varies depending on the duration and severity of the hypophosphatemia and affects several organ systems. Among other serious effects, hypophospha

Toxicology and carcinogenesis studies of pulegone (CAS No. 89-82-7) in F344/N rats and B6C3F1 mice (gavage studies).

Several essential oils contain pulegone and are used for flavoring foods, drinks, and dental products, as fragrance agents, and in herbal medicines. Pulegone was nominated for study by the National Institute of Environmental Health Sciences based on the potential for human exposure and the absence of carcinogenicity data. Male and female F344/N rats and B6C3F1 mice received pulegone (approximately 96% pure) by gavage for 2 weeks, 3 months, or 2 years. Genetic toxicology studies were conducted in Salmonella typhimurium, Escherichia coli, and mouse peripheral blood erythrocytes. 2-WEEK STUDY IN

Tumor Biology Hides Novel Therapeutic Approaches to Diffuse Large B-Cell Lymphoma: A Narrative Review.

Diffuse large B-cell lymphoma (DLBCL) is a malignancy of immense biological and clinical heterogeneity. Based on the transcriptomic or genomic approach, several different classification schemes have evolved over the years to subdivide DLBCL into clinically (prognostically) relevant subsets, but each leaves unclassified samples. Herein, we outline the DLBCL tumor biology behind the actual and potential drug targets and address the challenges and drawbacks coupled with their (potential) use. Therapeutic modalities are discussed, including small-molecule inhibitors, naked antibodies, antibody-dru

Clonal hematopoiesis and its progression to myeloid neoplasms: insights into risk, biology, and therapeutic strategies.

Clonal hematopoiesis (CH) is defined by the clonal expansion of hematopoietic stem and progenitor cells harboring somatic mutations that confer a fitness advantage. CH is common with advancing age and becomes nearly ubiquitous in middle age. Although typically asymptomatic, CH is associated with an increased risk of hematologic malignancies particularly myeloid neoplasms (MN), diverse non-malignant conditions, and all-cause mortality. Over the past decade, research has provided major insights into the origins of CH. In addition to aging, CH is promoted by environmental exposures, inherited gen

Current perspectives on KMT2A fusion proteins and menin inhibition in paediatric acute myeloid leukaemia.

The therapeutic landscape of acute myeloid leukaemia (AML) has evolved beyond the classic '7 + 3'/DA regimen, through the approval and incorporation of targeted treatments in both front-line and relapsed/refractory settings. Indeed, the use of selective BCL-2 antagonists (e.g. venetoclax) and FLT3 inhibitors (e.g. midostaurin, gilteritinib) which target specific molecular characteristics of leukaemic cells, has enhanced outcomes and survival rates. Arguably one of the most exciting advancements has been the clinical development of menin inhibitors for the treatment of patients harbouring speci

Genomic instability and genetic heterogeneity in aging: insights from clonal hematopoiesis (CHIP), monoclonal gammopathy (MGUS), and monoclonal B-cell lymphocytosis (MBL).

Aging is a multifaceted process characterized by a gradual decline in physiological function and increased susceptibility to a range of chronic diseases. Among the molecular and cellular mechanisms driving aging, genomic instability is a fundamental hallmark, contributing to increased mutation load and genetic heterogeneity within cellular populations. This review explores the role of genomic instability and genetic heterogeneity in aging in the hematopoietic system, with a particular focus on clonal hematopoiesis of indeterminate potential (CHIP), monoclonal gammopathy of undetermined signifi

Monocyte Involvement in the Pathogenesis of Myeloproliferative Neoplasms.

Classical BCR-ABL-negative myeloproliferative neoplasms are a heterogeneous group of hematologic malignancies, including essential thrombocythemia, polycythemia vera, and primary myelofibrosis. Monocytes, immune cells derived from hematopoietic stem cells, exhibit significant heterogeneity and contribute to immune regulation through cytokine secretion and differentiation into dendritic cells and macrophages. Aberrant monocytes are associated with the prognosis of MPNs, particularly PMF. Furthermore, these altered monocytes play a critical role in the pathogenesis and progression of MPNs. This
