Viral Meningitis01:18

Viral Meningitis

96
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

36
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

Epilepsy and Seizures: Overview

1.7K
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Arboviral Encephalitis01:25

Arboviral Encephalitis

25
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Seizures: Classification01:13

Seizures: Classification

2.2K
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Summary
This summary is machine-generated.

Sepsis-associated encephalopathy (SAE) is a common neurological complication of sepsis, presenting with diffuse brain dysfunction. Diagnosis is challenging, requiring exclusion of other causes, with limited management options beyond treating the infection.

Area of Science:

  • Neurology
  • Critical Care Medicine
  • Infectious Diseases

Background:

  • Sepsis-associated encephalopathy (SAE) is a frequent neurological complication of sepsis.
  • It involves diffuse brain dysfunction without direct central nervous system infection.
  • SAE pathophysiology is complex, involving vascular damage, inflammation, and blood-brain barrier disruption.

Purpose of the Study:

  • To review the diagnostic approach to SAE.
  • To discuss SAE epidemiology, pathophysiology, clinical presentation, and differential diagnoses.

Main Methods:

  • Literature review of SAE.
  • Analysis of diagnostic challenges and management strategies.

Main Results:

  • SAE presents with a wide range of cognitive impairments.
  • Diagnosis is often by exclusion due to lack of specific biomarkers and confounding factors like sedation.
  • Management is primarily supportive and focused on the underlying sepsis.

Conclusions:

  • SAE requires high clinical suspicion, especially in early sepsis.
  • Improved diagnostic tools and targeted therapies are needed.
  • Awareness of SAE is crucial for timely recognition and management in critically ill patients.
