Summary
Delayed-onset spontaneous intraparenchymal tension pneumocephalus is a rare complication after head trauma. This case highlights a delayed presentation of this condition, requiring urgent surgical intervention.
Area of Science:
- Neurosurgery
- Trauma Surgery
- Neurology
Background:
- Pneumocephalus is a known complication following head trauma.
- Tension pneumocephalus, a severe form, is uncommon.
- Delayed-onset and isolated intraparenchymal tension pneumocephalus are exceptionally rare.
Observation:
- A 35-year-old male presented with urinary incontinence, vision loss, and cerebrospinal fluid rhinorrhea.
- Symptoms appeared two months after recovery from bifrontal hemorrhagic contusions due to a road traffic accident.
- Computed tomography revealed intraparenchymal/intracerebral tension pneumocephalus.
Findings:
- The patient was diagnosed with delayed-onset isolated intraparenchymal tension pneumocephalus.
- Urgent decompressive surgery and skull base defect repair were performed.
Implications:
- This case underscores the importance of considering delayed-onset intraparenchymal tension pneumocephalus in patients with relevant neurological deficits post-trauma.
- Early diagnosis and surgical intervention are crucial for favorable outcomes.
- Further research into the mechanisms and management of delayed-onset spontaneous pneumocephalus is warranted.

Tension
13.7K
Tension is a force along the length of a medium, in particular, a force carried by a flexible medium, such as a rope or cable. The word "tension" comes from Latin, meaning "to stretch". Not coincidentally, the flexible cords that carry muscle forces to other parts of the body are called tendons. Any flexible connector, such as a string, rope, chain, wire, or cable, can exert pull only parallel to its length; so, a force carried by a flexible connector is a tension with a...

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

Surface Tension of Fluid
1.5K
Surface tension is a fundamental property of fluids, occurring at the boundary between a liquid and a gas or between two immiscible liquids. This phenomenon arises from the cohesive forces between molecules at the fluid's surface, creating an effect similar to a stretched elastic membrane. Inside each fluid, molecules are equally attracted in all directions by neighboring molecules, but surface molecules experience a net inward force, resulting in surface tension.

Surface Tension and Surface Energy

When a paint brush is immersed in water, the bristles wave freely inside the water. When it is taken out, the bristles stick together. The reason behind this effect is surface tension.
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...

Tension Response at Adherens Junctions
3.5K
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.

DNA Isolation
44.9K
DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...
