Insights

Disconnection of lumboperitoneal (LP) shunts can lead to cerebrospinal fluid (CSF) leakage through fibrous sheaths. Evaluating asymptomatic patients with shuntography can confirm patency and prevent complications before shunt removal.

Area of Science:

  • Neurosurgery
  • Biomaterials Science

Background:

  • Lumboperitoneal (LP) shunts are used to treat cerebrospinal fluid (CSF) disorders.
  • Catheter disconnection is a known complication of LP shunts.
  • The patency of fibrous sheaths around disconnected shunts for CSF passage is not well-established.

Observation:

  • A connective tissue sheath forms around peritoneal shunt tubing as a biological response.
  • A case study of a young patient with a disconnected LP shunt revealed a patent persistent fibrous tract.
  • This tract potentially allowed for CSF passage despite shunt disconnection.

Findings:

  • The literature lacks definitive proof regarding CSF passage through disconnected LP shunt fibrous sheaths.
  • This case provides evidence supporting the possibility of CSF flow through such sheaths.
  • Asymptomatic shunt disconnection warrants further investigation into sheath patency.

Implications:

  • Shuntography may be a valuable diagnostic tool for asymptomatic patients with disconnected LP shunts.
  • Identifying a patent fibrous tract could influence decisions regarding shunt removal.
  • Preventing complications associated with shunt removal in such cases is crucial.

Globular and Fibrous Proteins

Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities.
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...

Neuronavigation and Laparoscopy Guided Ventriculoperitoneal Shunt Insertion for the Treatment of Hydrocephalus

Patient outcomes of ventriculoperitoneal (VP) shunt surgery, the mainstay treatment for hydrocephalus in adults, are poor due to high shunt failure rates. We present intraoperative footage of VP shunt insertion using neuronavigation and laparoscopy guidance, with the goal to reduce the risks of proximal and distal shunt catheter failures, respectively.

Shunt Admittances

Shunt admittances play a crucial role in the analysis of transmission lines, particularly for three-phase systems with neutral conductors. When a uniformly charged conductor is positioned above the Earth, it induces an equal but opposite charge on its surface. This interaction creates electric field lines between the conductor and the Earth.
To model this effect, the method of images is employed. This method involves replacing the Earth with an image conductor that mirrors the original...

In Vitro Persister Assay: A Method to Evaluate the Effect of Osmolytes on Bacterial Persistence

In this video, we demonstrate a method to evaluate the effect of osmolytes on the formation of bacterial persisters. The bacterial cells are first exposed to osmolytes to induce osmotic stress, triggering persister formation, then treated with antibiotics to enumerate the...

Fibrous Proteins00:55

Fibrous Proteins

Fibrous proteins are either long and narrow proteins or assemble to form long and thin structures. They contain repetitive units and usually consist of either alpha helices or beta sheets and, in rare cases, a mix of both. The amino acids in the primary structure often consist of repeating amino acid sequences. The role of fibrous proteins is primarily structural. Many are located in the extracellular matrix and are present in connective tissues to impart strength and joint mobility. They are...
