Atherosclerosis is an inflammatory disease of the arteries responsible for a high rate of morbidity and mortality worldwide. The objective of this study was to associate the histopathologic and immunohistochemical aspects of tongue inflammation with aortic and coronary atherosclerosis in autopsied humans. A total of 4378 autopsy reports were analyzed, and cases were included in the study if fragments of the individual's tongue, aorta, and coronary artery were available for analysis (N = 16).

Methods: Patients with ovarian epithelial neoplasia (n=77) were studied with a prospective cohort. The CD56 immunostaining was evaluated in the peritumoral stroma.
The objectives of this study were to investigate the immunohistochemical expression of markers of mast cells and M2 macrophages in benign and malignant ovarian neoplasms and to examine the prognostic value of this expression in ovarian cancer. The study was performed with samples from 32 patients, divided into benign ( = 16) and malignant ( = 16) neoplasm groups. Samples obtained by surgical resection were submitted to immunohistochemical analysis.

Composed of leukocytes and platelet-rich fibrin, an autologous membrane has great potential for tissue repair. The purpose of this study was to assess the use of this membrane (associated or not associated with diced cartilage) as an alternative to techniques such as the camouflage and filling; correction of irregularities of the dorsum, nose tip, soft triangle, and K zone; filling in of dead space; skin camouflage; and an improvement in the healing process in primary or secondary rhinoplasties.

However, it has not known whether such chronic use changes the presence of gastrin, delta, and enterochromaffin-like cells in the stomach or the relationship between gastrin and delta cells.
Aim: To analyze the number of gastrin-producing gastrin cells, somatostatin-producing cells, and histamine-producing cells in patients who were chronic users of proton pump inhibitor, with or without related Helicobacter pylori infection.
Smoking is a risk factor for serious health problems and is associated with several changes in the tissues of the oral cavity. The aim of this study was to evaluate the collagen percentage, mast cells density, intensity of immunolabeled cells by anti-HIF-1α in the musculature lingual of rats exposed to secondhand smoke. Twenty-seven female Wistar albino rats were divided into three groups: rats not exposed to tobacco smoke inhalation (Control group) (n=7); rats exposed to smoke inhalation for 30 days (TAB 30) (n=10); and rats exposed to smoke inhalation for 45 days (TAB 45) (n=10).

This report presents epidemiological, clinical and outcome data from HIV-infected patients with histoplasmosis confirmed by culture and/or at necropsy who were admitted to a Brazilian teaching hospital. Data from 65 patients were obtained from their respective medical and necropsy records.

This study aimed to compare the percentage of collagen, the presence of inflammation, the density of chimase and tryptase mast cells, the area and density of lingual salivary gland acini in autopsied individuals with and without (CD). We analyzed 400 autopsy reports performed in a tertiary public hospital from 1999 to 2015 and selected all the cases in which tongue fragments were collected (27 cases), 12 with chronic CD without megaesophagus (CH) and 15 without CD (non-chagasic - NC).

The objectives of the study were to evaluate the expression of CD3, CD4, CD8 and CD20 in the peritumoral stroma of benign and malignant ovarian epithelial neoplasms and to relate them to prognostic factors in ovarian cancer.: We evaluated 77 patients (40 benign epithelial ovarian neoplasms and 37 malignant epithelial ovarian neoplasms).

Trypanosoma cruzi and Helicobacter pylori (HP) are pathogens that cause chronic diseases and have been associated with hypergastrinemia. The aim of this study was to evaluate the fasting gastrin levels in patients with different clinical forms of Chagas disease (CD), coinfected or not by HP. The enrolled individuals were outpatients attending at the university hospital.

Oxidative stress has been associated with the etiopathogenesis of recurrent miscarriages, preeclampsia, intrauterine growth restriction, and stillbirth. Both, the exacerbated consumption of the antioxidant enzymes superoxide dismutase, catalase and glutathione peroxidase, and the increased synthesis of reactive oxygen species, such as superoxide, peroxynitrite, and hydrogen peroxide, induce phospholipid peroxidation and endothelial dysfunction, impaired invasion and death of trophoblast cells, impaired decidualization, and remodeling of maternal spiral arteries.

Cancer-associated fibroblasts play a prominent role in this process. The aims of the study were to investigate 2 cancer-associated fibroblasts markers, alpha-smooth muscle actin (α-SMA), and fibroblast activation protein alpha (FAP) in the stromal microenvironment of benign and malignant ovarian epithelial neoplasms, and to relate their tissue expression with prognostic factors in ovarian cancer.

In normal pregnancies, this process depends on the balance between the expression of angiogenic factors and antiangiogenic factors, which are responsible for remodeling the spiral arteries, as well as for neoangiogenesis and fetal development.
Purpose: The aim of this review is to discuss the main scientific findings regarding the role of angiogenic and antiangiogenic factors in the etiopathogenesis of preeclampsia.
Peri-implantitis is an infectious disease characterized by inflammation of the tissues surrounding the implant, bleeding on probing with or without suppuration, and bone loss. Peri-implant lesions contain a leukocyte infiltrate of plasma cells, lymphocytes, macrophages and neutrophils. A survey of the literature did not show any studies reporting an association between hypoxia and peri-implantitis.

Initially considered a benign lipotamous lesion of the soft tissues, nowadays they are considered to be a locally aggressive tumor. They occur mainly in the foot and ankle of women in their fifth and sixth decades, although they may be found in any place in the lower limbs and, more rarely, in other parts of the body.

Material Or Subjects: Thirty-two colon fragments were selected from chagasic patients with megacolon (n=25) and nonchagasic patients without megacolon (n=7).
Methods: Immunohistochemistry for Gal-1, Gal-3 and Gal-9 was performed using a common light microscope and the results were scored 0-3 according to labeling intensity.
Pelvic tuberculosis is a type of extrapulmonary tuberculosis. The disease is accompanied by clinical and laboratory findings which may be unspecific and present aspects of other diseases, including gynecological malignancies. In this report, the authors presented a case of pelvic tuberculosis associated with peritoneal tuberculosis in a young woman exhibiting imaging and tumor markers consistent with ovarian neoplasm.

The intense inflammatory response mediated by IL-1β, TNF-α, PAF, IFN-γ and IL-6, PGE and MMP-1 and MMP-9 causes fetal membrane damage and rupture, increased uterine contractions and biochemical and structural changes in the cervix. Furthermore, preterm neonates have deficient innate and adaptive immune responses characterized by reduced levels of IgG, opsonization and phagocytosis, as well as increased activation of Th1 cells in relation to Th2 cells.
