Ultrasound diagnosis of femoral nerve neurostenalgia : a cause of hip pain in a young adult
Femoral neurostenalgia is a compressive neuropathy which is an uncommon cause of hip pain in active young adults. Compression of the nerve can cause debilitating pain and an inability to walk. Correct clinical diagnosis and correct treatment can result in complete relief of symptoms. We present a case of a young female with a spontaneous
acute onset of severe hip pain for ten months. After seeing several specialists and having undergone numerous special
investigations, femoral nerve compression by the iliopsoas was demonstrated on ultrasound, but only confirmed during surgery for a suspected femoral hernia. After decompression of the nerve the patient was completely pain free.http://www.charpublications.co.za/C_JournalsORTH.aspay201
Working With the Tangible: Radiation, A Twenty-First Century Interpretation
The intangible means of expression was a topic of investigation across various disciplines when Michael Chekhov was developing his pedagogic practice. In the world of science, Harold Saxton Burr and Albert Szent-Gyorgi, were examining the body as a conductor of energy. Their research was relevant to Chekhov's approach regarding how the actor communicates with internal and external stimulus. This article begins with an analysis of Chekhov's theories on Radiation, it moves on to offer insights into science and energy work with reference to cell Biologist James Oschman and his concept of âthe living matrixâ and Mae Wan Ho's critique of quantum cohesion. Examples of praxis demonstrate that contemporary science and body work can provide a greater understanding of how Radiation and the organisation of energy can enhance performance
Electrical Impedance of Acupuncture Meridians: The Relevance of Subcutaneous Collagenous Bands
Background: The scientific basis for acupuncture meridians is unknown. Past studies have suggested that acupuncture meridians are physiologically characterized by low electrical impedance and anatomically associated with connective tissue planes. We are interested in seeing whether acupuncture meridians are associated with lower electrical impedance and whether ultrasound-derived measures â specifically echogenic collagenous bands- can account for these impedance differences. Methods/Results: In 28 healthy subjects, we assessed electrical impedance of skin and underlying subcutaneous connective tissue using a four needle-electrode approach. The impedances were obtained at 10 kHz and 100 kHz frequencies and at three body sites- upper arm (Large Intestine meridian), thigh (Liver), and lower leg (Bladder). Meridian locations were determined by acupuncturists. Ultrasound images were obtained to characterize the anatomical features at each measured site. We found significantly reduced electrical impedance at the Large Intestine meridian compared to adjacent control for both frequencies. No significant decrease in impedance was found at the Liver or Bladder meridian. Greater subcutaneous echogenic densities were significantly associated with reduced impedances in both within-site (meridian vs. adjacent control) and between-site (arm vs. thigh vs. lower leg) analyses. This relationship remained significant in multivariabl

Al-FáŸčRáŸčBáż, Metaphysics, and the Construction of Social Knowledge: Is Deception Warranted If It Leads to Happiness?
When questioning whether political deception can be ethically warranted, two competing intuitions jump to the fore. First, political deception is a fact of human life, used in the realpolitik of governance. Second, the ethical warrant of truth asserts itself as inexorably and indefatigably preferable to falsehood. Unfortunately, a cursory examination of the history of philosophy reveals a paucity of models to marry these basic intuitions. Some thinkers (e.g., Augustine, Aquinas, Grotius, Kant, Mill, and Rawls) privilege the truth by neglecting the realpolitik, i.e., the truth is inviolate. Others (e.g., Machiavelli, Bentham, and the often infamous cachĂ© of 20th century dictators) focus upon the realpolitik to the exclusion of the primacy of the truth. A third group of critical thinkers (e.g., Arendt and Bok) examine the topic but offer no positive, systematic treatment of deception. Lacking are theories which simultaneously recognize that political untruth is often necessary, but that untruth is only justified when a) truth is politically impossible, b) the necessity of untruth is demonstrable, and c) the truth can be replaced with a minimally injurious untruth. Plato offers one such account in the Republic, arguing that deceit must be applied medicinally to the city. However, his account is problematic in detail. One of Platoâs inheritors, the 10th century thinker al-FÄrÄbÄ«, advanced Platoâs theoretical account, arguing that political governance requires restrained political deception. This deception, the expression of philosophical truths through the symbols of religion, meets the criteria mentioned above, being necessary, demonstrably necessary, and minimally injurious. But while al-FÄrÄbÄ« provides a valuable model for what justified political deception could look like, the lengths to which he must go in order to create a viable model for political deception reveals the untenability of the notion of justified political deception writ large. One must orchestrate an entire cosmos around the notion, notably a cosmos that does not match our own. One must adopt very specific conceptions of human nature, association, and happiness, as well as a particular metaphysics and epistemology. For, while al-FÄrÄbÄ« shows that political deception can be justifiable, he also reveals its unjustifiability outside an idealized setting
