Insights

Chronic endometritis, a common gynecological condition, is often asymptomatic and difficult to detect. Immunohistochemistry revealed its prevalence and highlighted differences between symptomatic and asymptomatic cases.

Area of Science:

  • Gynecologic pathology
  • Reproductive immunology

Background:

  • Chronic endometritis is often asymptomatic and challenging to diagnose with conventional methods.
  • Immunohistochemistry offers a more sensitive approach to identifying this condition.

Purpose of the Study:

  • To investigate the clinicopathological features of chronic endometritis using immunohistochemistry.
  • To determine the prevalence and characteristics of chronic endometritis in endometrial specimens.

Main Methods:

  • Immunohistochemistry for syndecan-1 (a plasmacyte marker) was performed on 234 archival endometrial specimens.
  • Endometrial morphology was dated, and stromal plasmacyte infiltration was quantified.
  • Clinical data from patient charts were correlated with pathological findings.

Main Results:

  • Chronic endometritis was detected in 11.1% of examined samples.
  • The condition occurred equally in proliferative and secretory phases.
  • 23.1% of cases were asymptomatic, with less pronounced stromal infiltration and morphological delay compared to symptomatic cases.

Conclusions:

  • Chronic endometritis is a prevalent gynecological condition, frequently asymptomatic.
  • No significant menstrual cycle-dependent variation in chronic endometritis occurrence was observed.

Trichomoniasis01:18

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Endocarditis I: Introduction01:25

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
