Summary
Dural port therapy (DPT) is a chiropractic technique using the sacrum to balance the spine and cranium. This safe procedure reduces meningeal tension and may influence the nervous system, warranting further study.
Area of Science:
- Chiropractic Medicine
- Osteopathic Manipulative Medicine
- Neuroscience
Background:
- Dural port therapy (DPT) is a chiropractic procedure.
- It is effectively used with Sacro-Occipital Technique (SOT) procedures.
- DPT utilizes the sacrum as a lever to influence and balance the spine and cranium via the meningeal system.
Purpose of the Study:
- To present the rationale and research behind DPT's method of affecting the craniospinal system.
- To explain the relationship between DPT, the craniospinal system, and the meninges.
- To introduce basic and alternative methods for DPT application.
Main Methods:
- The study presents the theoretical basis and rationale for Dural Port Therapy.
- It discusses the application of DPT in conjunction with Sacro-Occipital Technique.
- Basic and alternative methods of DPT are described.
Main Results:
- DPT reduces tension, lesions, torque, and stress in the sacral, spinal, and cranial dura meninges.
- It alleviates dural sleeve vasomotor interference.
- The procedure appears safe for patients with osteoporotic conditions or fractured vertebrae, where spinal thrusts may be contraindicated.
Conclusions:
- DPT effectively reduces meningeal tension and stress throughout the craniospinal axis.
- The technique offers a potentially safe alternative for patients with contraindications to spinal thrusts.
- The powerful influence of DPT on the nervous system merits further investigation.

Drug Delivery: Parenteral Route
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Portal Hypertension
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
