Summary
Ocular microflutter, a rare involuntary eye movement, can cause oscillopsia after viral illness. Video-oculography is crucial for diagnosing this subtle condition, which may improve but not fully resolve.
Area of Science:
- Ophthalmology
- Neuroscience
Background:
- Saccadic intrusions are involuntary eye movements disrupting visual fixation.
- Ocular flutter and opsoclonus are known saccadic intrusions without intersaccadic intervals.
- Ocular microflutter is a rare variant with very small saccade amplitudes.
Observation:
- A patient presented with acute-onset oscillopsia after a non-specific viral illness.
- Video-oculography revealed ocular microflutter.
- Extensive investigations led to a diagnosis of isolated idiopathic or post-viral ocular microflutter.
Findings:
- Ocular microflutter is a saccadic intrusion rarely documented in medical literature.
- Its small amplitude may lead to it being clinically overlooked.
- Video-oculography is essential for accurate diagnosis.
Implications:
- This case highlights ocular microflutter as a potential cause of post-viral oscillopsia.
- The condition showed favorable evolution with partial improvement of symptoms.
- Routine use of video-oculography may improve detection rates for ocular microflutter.

273
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

1.3K
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

729
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

01:21Acute Respiratory Failure-I
1.1K
Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
