Skin Diseases and Disorders01:23

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
Sexually Transmitted Infections01:26

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Microbiome of the Eye01:22

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
Diabetic Retinopathy01:27

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Área de la Ciencia:

  • Oftalmología Oftalmología.
  • Reumatología Reumatología.
  • Medicina interna es la medicina interna de las enfermedades.

Sus antecedentes:

  • Las enfermedades inflamatorias sistémicas afectan con frecuencia a las estructuras oculares, incluidas la esclerótica, la córnea, la retina y la órbita.
  • Estas afecciones representan un riesgo significativo para la visión y abarcan trastornos vasculares y enfermedades inflamatorias granulomatosas.
  • Las complicaciones oculares pueden surgir por inflamación directa, isquemia (por ejemplo, arteritis), retinopatía hipertensiva o efectos secundarios de medicamentos como la maculopatía por cloroquina.

Objetivo del estudio:

  • Para resaltar las diversas manifestaciones oculares de las enfermedades inflamatorias sistémicas.
  • Para enfatizar el desafío diagnóstico planteado por distinguir la inflamación intraocular endógena de la infección.
  • Para subrayar la importancia de excluir la infección en poblaciones específicas de pacientes.

Principales métodos:

  • Revisión de las presentaciones clínicas y asociaciones conocidas entre condiciones inflamatorias sistémicas y enfermedades oculares.
  • Análisis de las posibles causas de la pérdida de la visión, incluida la inflamación directa, la isquemia y la toxicidad de los medicamentos.
  • Discusión de las estrategias de diagnóstico, en particular el papel de las investigaciones microbiológicas en casos sospechosos de infección.

Principales resultados:

  • La inflamación sistémica puede conducir a daño ocular directo y complicaciones secundarias como isquemia y maculopatía inducida por medicamentos.
  • Las infecciones oculares, particularmente en individuos inmunodeprimidos, pueden imitar la inflamación intraocular endógena.
  • La infección debe considerarse y excluirse mediante el muestreo y cultivo apropiados de fluidos y tejidos intraoculares en pacientes de alto riesgo.

Conclusiones:

  • La participación ocular en enfermedades inflamatorias sistémicas requiere una evaluación exhaustiva.
  • La diferenciación cuidadosa entre la inflamación y la infección es fundamental para el manejo adecuado y la preservación de la vista.
  • La paracentesis diagnóstica y los cultivos microbianos son esenciales en pacientes inmunosuprimidos con sospecha de inflamación intraocular.
