PURPOSE In uveal melanoma, both tumor size and an inflammatory phenotype have been shown to correlate with a poor clinical prognosis. The purpose of this study was to identify whether inflammatory cytokines were present in the vitreous of eyes with uveal melanoma and to determine whether the vitreal concentration of cytokines correlated with prognostic variables such as tumor dimensions and imm...

Dental pulp represents a specialized connective tissue enclosed by dentin and enamel, the most highly mineralized tissues of the body. Consequently, the direct examination as well as pathological evaluation of dental pulp is difficult. Within this anatomical context, our study aimed to evaluate the correlation between dental pulp lesions and clinical diagnosis. Pulpectomies were performed for 5...

The presence of plasma cells in melanocytic lesions has been considered in literature as a sign of concern, when evaluated in the appropriate context. Plasma cells have been evaluated in halo nevus, but they are not frequently reported in non-halo common acquired nevus. Our claim was to study how common and frequent plasma cells are in the latter type of nevi. Therefore, we examined 280 of thes...

OBJECTIVES Acute inflammation in idiopathic inflammatory myopathies (IIM) causes oedema that can be visualized by magnetic resonance imaging (MRI). The inflammatory infiltrate in IIM is thought to be frequently in a focal distribution. The aim of this study is to better evaluate the relationship of MR image of thigh muscles to clinical and histological parameters in patients with IIM. METHODS...

BACKGROUND Squamous cells carcinoma is the most important malignant tumor with primary site in the oral cavity and, given the great exposure of mucosa and lips to the etiologic factors of this neoplasm, its incidence is high. Investigation of the prognostic determinants is significant for the expectations of treatment proposal and cure of the patient. The local immune response represented by pe...

PURPOSE To compare histological changes induced by antiglaucoma medications in the rabbit conjunctiva. METHODS Fifty New Zealand rabbits were divided in 5 groups of 10 animals. The left eyes were treated daily with one drop of bimatoprost 0.03%, travoprost 0.004%, latanoprost 0.005%, timolol maleate 0.5% or artificial tears containing benzalkonium chloride (BAK) for 30 days. The right eyes se...

Cytokine control of the synovial infiltrate is a central process in the development of inflammatory arthritis. In this study, we combine genetic approaches and intervention strategies to describe a fundamental requirement for IL-6-mediated STAT3 signaling in orchestrating the inflammatory infiltrate in monoarticular and systemic models of experimental arthritis. STAT3 activation via the common ...

Progression of liver disease in chronic hepatitis C depends on several factors related to the host, virus and the environment which deserves further investigations. 120 candidates for blood donation with hepatitis C virus were divided into three groups according to alcohol intake: abstainers, light drinkers and heavy drinkers. Liver histopathology alterations, namely architectural staging, peri...

Lymphocyte is one of the subtypes of white blood cell (WBC) in immune system. Lymphocytes contain T cells, natural killer cells , and B cells. They are the head type of cell found in lymph, which for this reason the name "lymphocyte". Lymphocytes can be recognized by their large nucleus. Infiltration of immune cells in the central nervous system (CNS) helps the start of chronic pain. ...

Normal Pressure hydrocephalus (NPH) is characterized by gait apraxia, urinary incontinence, and dementia. Mixed connective tissue disease (MCTD) is an autoimmune connective tissue disease that has never been reported to cause NPH. Our patient was a 67-year man with a one-year history of gradual worsening gait and balance, urinary urgency with urge incontinence and decreased short-term memory. P...
