Impact of immune checkpoint inhibitors on atherosclerosis progression in patients with lung cancer.

Background: Patients with lung cancer face a heightened risk of atherosclerosis-related cardiovascular events. Despite the strong scientific rationale, there is currently a lack of clinical evidence examining the impact of immune checkpoint inhibitors (ICIs) on the advancement of atherosclerosis in patients with lung cancer. The objective of our study was to investigate whether there is a correlation between ICIs and the accelerated progression of atherosclerosis among individuals with lung cancer.

Serial Measurement of Global Longitudinal Strain Among Women With Breast Cancer Treated With Proton Radiation Therapy: A Prospective Trial for 70 Patients.

Purpose: Conventional photon radiation therapy (RT) for breast cancer is associated with a reduction in global longitudinal strain (GLS) and an increase in troponin, N-terminal pro hormone B-type natriuretic peptide (NT-proBNP), and incident heart failure. The cardiac radiation exposure with proton-RT is much reduced and thus may be associated with less cardiotoxicity. The objective was to test the effect of proton-RT on GLS, troponin, and NT-proBNP.

Aspiration and Brushing Cytology in tumors and tumor-like conditions of the tongue: A Study of 27 Cases.

Background: Lesions of the tongue have a broad differential diagnosis ranging from benign idiopathic processes to infections, cancers, and infiltrative disorders. An important thing to remember is that most tongue lesions will resolve spontaneously or with simple therapy within a week, if not, they should be biopsied or evaluated further for a definitive diagnosis of a potentially serious disorder. Some tongue lesions may be clues to other underlying illnesses which require further evaluation Tongue lesions are traditionally evaluated by surgical biopsy.

Liquid Based Preparation (LBP) cytology versus Conventional Cytology (CS) in FNA samples from breast, thyroid, salivary glands and soft tissues. Our experience in Crete (Greece).

Background: The improvement in quality of cytological preparations with the use of LBP methodology has been well-documented, but the cytological artifacts resulting from this technique have not been adequately described. This study describes and illustrates the cytological artifacts introduced by LBP technique when used on fine-needle aspirates (FNAs), and evaluates these artifacts as potential diagnostic pitfalls.

Study Design: We reviewed a total of 96 FNAs simultaneously processed by both conventional smears and LBP.

Accessory parotid gland carcinoma ex pleomorphic adenoma. Case study diagnosed by fine needle aspiration.

Objective: The accessory parotid gland is salivary tissue separated from the main parotid gland and lying on masseter muscle. It has secondary duct emptying into the Stensen's duct. The accessory parotid gland exists in 21-61% of individuals.

Endometriosis involving the rectus abdominis muscle and subcutaneous tissues: fine needle aspiration appearances.

Objective: Endometriosis is defined as functioning endometrial tissue outside the uterine cavity. It occurs in up to 15% of menstruating females and in most cases is located within the pelvis. Endometrial implants, however have been described in soft tissues, particularly in the skin and subjacent tissues of surgical scars, and diagnosis might be problematic.

Fibroadenoma masquerading carcinoma on fine-needle aspiration of the breast.

Objective: Benign and malignant lesions of the breast may have similar appearances on fine-needle aspiration cytology. We report a case of fibroadenoma that was diagnosed as carcinoma by cytology.

Case Study: Breast fine-needle aspiration biopsy was highly cellular and composed of bland-appearing spindle/columnar cells that could represent either epithelial or stromal cells; the case was reported as positive and the patient had subsequent excisional biopsy taken.

A stromal myoid cell line provokes thymic T-cell immigration at the second and third gestational trimesters.

Unlabelled: Once lymphoid precursors enter the thymus form the blood stream, they come into contact with thymic stromal cells that guide their maturation into functionally competent T cells. Thymic myoid cells are one such cell type. They have been described as a regular constituent of the thymus of embryonic and young vertebrates and express muscle proteins including myosin, desmin, acetylcholine receptor (AChR), C-protein, MyoD, troponin T, rapsyn, and utrophin.

Normal development of fetal hepatic haematopoiesis during the second trimester of gestation is upregulated by fibronectin expression in the stromal cells of the portal triads.

Objective: in midtrimester fetuses the principal site of hematopoiesis is the liver. In hematopoietic organs, stromal cells such as fibroblasts, epithelial cells, and macrophage-like cells develop networks to maintain hematopoiesis, i.e.

CD30 (Ber-H2) expression by thymocytes and thymic epithelial cells during the late first and second trimester of gestation: an immunohistochemical and in situ hybridization (ISH) study.

Background: The exact biological function of CD30 in the thymus during development has been only partially elucidated, although data indicate it may be involved in negative selection. This study was prompted by the observation of a positive reaction of thymic epithelial cells (TECs), Hassall's corpuscles, and thymocytes with the monoclonal antibody CD30 during the late first and second trimester.

Material/methods: Twenty paraffin-embedded fetal thymus specimens at the late first and second trimester were investigated by conventional histology and immunohistology for CD30 expression.

Induction of hepatic haematopoiesis with fibronectin expression by EMT stromal cells during the second trimester of development.

Primary MALT lymphomas of the stomach: a pathological study of 18 cases.

Aim: It is doubtful that whoever is suffering from gastric malt lymphoma will escape from the disease, if treated with medication against helicobacter pylori.

Material And Methods: A cohort of 18 patients was analysed. Ten hosts had primary gastric malt lymphoma and were treated with gastric resection as the initial therapy.

Concurrent low grade B-cell non-Hodgkin's lymphoma of MALT type arising in the large intestine, small intestine and stomach.

Low-grade non-Hodgkin's lymphomas (NHL) of mucosa associated lymphoid tissue (MALT) are indolent neoplasms that, although tending to remain localized for many years, may spread to other mucosal sites. Despite increasing identification of concurrent gastric and intestinal lymphoma of MALT type, the clonal relationship between the tumors and their sequential development are poorly understood. It is also unknown whether the development of these concurrent tumors is closely associated with direct antigen stimulation, which is thought to play an important role in the clonal expansion of low grade MALT lymphomas.

Loss of chromosome 1 in myxopapillary ependymoma suggests a region out of chromosome 22 as critical for tumour biology: a FISH analysis of four cases on touch imprint smears.

Objective: Ependymomas are glial tumours. They constitute approximately 5-10% of intracranial tumours and are tumours which can recur. Predictive factors of outcome in ependymomas are not well established.

Distribution of somatostatin in pancreatic ductal adenocarcinoma remodels the normal pattern of the protein during foetal pancreatic development: an immunohistochemical analysis.

Aim: To determine the immunoreactivity of somatostatin during the development of the human fetal pancreas and pancreatic ductal adenocarcinoma, given that, somatostatin-positive cells were demonstrated either into its embryonic anlage or into pancreatic cancer.

Methods: Tissue sections from 15 pancreatic fetal specimens, and an equal number of ductal adenocarcinoma specimens were assessed.

Results: The density of positive cells in the primitive exocrine ductal epithelium and endocrine epithelium was significantly different from the relevant density in the neoplastic pancreatic tissue of mixed (ductal-endocrine) and pure ductal type (P1=0.

An unusual case of posttransplant peritoneal primary effusion lymphoma with T-cell phenotype in a HIV-negative female, not associated with HHV-8.

Primary effusion lymphoma (PEL) is a recently individualized form of non-Hodgkin's lymphoma (WHO classification) that mainly develops in HIV infected males, more frequently in homosexuals and advanced stages of the disease (total CD4+ lymphocyte count below 100-200/microL). Occasionally, it appears in other immunodepressive states (such as solid organs transplant period) and even, although very rarely, in immunocompetent patients. From a pathogenetic point of view, PEL has been related to Kaposi's sarcoma associated herpes virus (also named human herpesvirus 8, HHV-8), an etiological factor of Kaposi's sarcoma.
