Isolated Non-ascitic Peritoneal Carcinomatosis from Metastatic Prostate Cancer.

Prostate cancer most commonly metastasizes to bone, lung and liver. Omental metastasis of prostate cancer is extremely rare, with only a few cases reported in the literature, many of which have associated ascites. We present a case of non-ascitic omental metastasis of prostate cancer without any bone metastases. Furthermore, this patient has had two negative measurements of circulating tumor cells (CTCs) in the blood, suggesting a non-hematogenous route of metastasis to the omentum.

Fascia--Current knowledge and future directions in physiatry: narrative review.

Fascia can be considered part of the connective tissues that permeates the human body. However, in medical training its definition is not clear, and even among specialists its role is not completely understood. Physiatrists have a unique opportunity to add to the growing scientific and clinical knowledge about fascia, particularly about how this connective tissue network may apply clinically to musculoskeletal disorders. In this narrative review, the structure and function of fascia is discussed from the perspective of physiatry.

Deformations experienced in the human skin, adipose tissue, and fascia in osteopathic manipulative medicine.

CONTEXT: Osteopathic manipulative medicine techniques involve compressive and tangential forces to target the fascia. These forces are transmitted to the skin and adipose tissue before the fascia is encountered. Knowing the extent of deformation of these 2 tissue layers relative to the fascia will assist osteopathic physicians in evaluating techniques for manual therapies and adjusting these therapies to reduce patient discomfort and improve results. OBJECTIVE: To determine the magnitude of the forces transmitted to the skin, adipose tissue, and fascia, and to determine the magnitude of deformation produced in the skin and adipose tissue relative to the fascia using a mathematical model. METHODS: The large deformation theory of elasticity, valid for 3-dimensional deformations, was used to evaluate the forces that need to be applied such that a specified deformation is produced in any region of the skin, adipose tissue, or fascia layers. Similarly, if the forces are specified, then the deformation produced can be determined. RESULTS: The normal and tangential forces required to produce a deformation of 9% compression and 4% shear for the skin were 50 N and 11 N, respectively. Normal and tangential forces of about 100 N and 22 N were found for a similar deformation of fascia. For adipose tissue, these forces were 36 N and 8 N, respectively. In addition, the skin experienced more compression and shear-about 1.5 times as much as the fascia, and the adipose tissue experienced about 2.5 to 3.5 times the deformation of the fascia and 50% more than the skin when a given force was applied to the skin. CONCLUSION: The forces applied to the surface of the skin were transmitted through this layer and the adipose layer entirely to the fascia. Therefore, the skin and adipose tissue experienced the same magnitude of force as the fascia. However, the skin and adipose tissue experienced more compression and shear than the fascia.

Mathematical analysis of the flow of hyaluronic acid around fascia during manual therapy motions.

CONTEXT: More research is needed to understand the flow characteristics of hyaluronic acid (HA) during motions used in osteopathic manipulative treatment and other manual therapies. OBJECTIVE: To apply a 3-dimensional mathematical model to explore the relationship between the 3 manual therapy motions (constant sliding, perpendicular vibration, and tangential oscillation) and the flow characteristics of HA below the fascial layer. METHODS: The Squeeze Film Lubrication theory of fluid mechanics for flow between 2 plates was used, as well as the Navier-Stokes equations. RESULTS: The fluid pressure of HA increased substantially as fascia was deformed during manual therapies. There was a higher rate of pressure during tangential oscillation and perpendicular vibration than during constant sliding. This variation of pressure caused HA to flow near the edges of the fascial area under manipulation, and this flow resulted in greater lubrication. The pressure generated in the fluid between the muscle and the fascia during osteopathic manipulative treatment causes the fluid gap to increase. Consequently, the thickness between 2 fascial layers increases as well. Thus, the presence of a thicker fluid gap can improve the sliding system and permit the muscles to work more efficiently. CONCLUSION: The mathematical model employed by the authors suggests that inclusion of perpendicular vibration and tangential oscillation may increase the action of the treatment in the extracellular matrix, providing additional benefits in manual therapies that currently use only constant sliding motions.

Fascia Research Congress evidence from the 100 year perspective of Andrew Taylor Still.

More than 100 years ago A.T. Still MD founded osteopathic medicine, and specifically described fascia as a covering, with common origins of layers of the fascial system despite diverse names for individual parts. Fascia assists gliding and fluid flow and is highly innervated. Fascia is intimately involved with respiration and with nourishment of all cells of the body, including those of disease and cancer. This paper reviews information presented at the first three International Fascia Research Congresses in 2007, 2009 and 2012 from the perspective of Dr Still, that fascia is vital for organism's growth and support, and it is where disease is sown.

Veterans with diabetes receive arthroplasty more frequently and at a younger age.

BACKGROUND: A future increase in total joint arthroplasties in patients with diabetes seems likely considering the prevalence of osteoarthritis and diabetes mellitus are increasing. However, the rates of arthroplasty in the population of patients with diabetes are unclear. QUESTIONS/PURPOSES: We sought to determine whether lower extremity arthroplasties in a veteran population with diabetes is different from a similar population without diabetes. The following specific questions were asked: (1) Is the rate of TKA in veterans with diabetes higher than in those without diabetes? (2) Is the rate of THA in veterans with diabetes higher than in those without diabetes? (3) Are arthroplasty revision rates greater in veterans with diabetes than in veterans without diabetes? METHODS: The US Department of Veterans Affairs Health administrative data from fiscal year 2000 was used to identify persons with primary or secondary TKA or THA. The rate of surgeries among a diabetic population was compared with that among a nondiabetic population. RESULTS: The diabetic cohort received total joint arthroplasties at a higher rate than the nondiabetic cohort at all ages younger than 66 years, with a range of odd ratios from 1.3 to 3.4. In answer to our specific questions, (1) the rate of TKA (95% CI, 2.1-3.7), (2) the rate of THA (95% CI, 1.0-2.6), and (3) the rates of arthroplasty revision (95% CI, 0.9-5.8 TKA and 0.7-6.8 THA) were higher in veterans with diabetes. Furthermore, those with diabetes in the youngest age group studied received total joint arthroplasties and revision surgeries at approximately double the rates of those without diabetes. CONCLUSIONS: If these findings hold true for the population as a whole, they imply that clinicians in the United States may see a sharp increase in younger diabetic candidates for joint arthroplasty.

Fascia Research from a Clinician/Scientist's Perspective.

The upcoming Third International Fascia Research Congress will have much exciting information for the clinician, as well as for the clinical and basic science researcher. This paper provides a perspective from a clinician/scientist, including the fascial network of body-wide connections between and within individual cells, and sharing of loads between muscle and fascia. Basic studies of fibroblast cell shape show the impact of manual therapy, acupuncture, and yoga-like stretching at the cellular level. Advances in scientific equipment have made it possible to study a layer of hyaluronan fluid, which allows sliding between deep fascia and muscle. Collagen fibers within fascia affect both blood flow to muscles and lymphatic fluid flow.

Second international fascia research congress.

Findings from papers published by key speakers at the 2007 Fascia Research Congress are presented in preparation for the second congress, October 2009, in Amsterdam.The role of fascia is demonstrated in new scientific findings in mechanotransduction between the cytoskeletal structure and the extracellular matrix, and its implications for health and disease.the presence of contractile cells (myofibroblasts) within the fascial fabric. Clinicians are interested in their role in creating contractile tonus in the fascial fabric-how myofibroblasts form, how they are activated, and their influence on passive muscle tonus.the biomechanical properties of fascial tissues: creep, relaxation, hysteresis, effect of sustained spinal flexion on lumbar tissues, strain-induced hydration changes, myofascial manipulation, and fascial viscoelastic deformation. These properties underlie the response of these tissues to therapy.how fascia is innervated, and how proprioception and pain are created, detected, and modulated by the spinal cord and the rest of the nervous system.forms of mechanical signaling within the fascial matrix, such as the tugging in the collagen matrix created by twisting acupuncture needles.new techniques for measurement of fascial motion in living tissue.

Department of Veterans Affairs-Medicare dual beneficiaries with stroke: where do they get care?

This study examined care patterns among stroke patients with diabetes who were dually eligible for Department of Veterans Affairs (VA) and Medicare services. We investigated the location (VA hospital or community-based hospital reimbursed by Medicare) of initial and postacute stroke care during a 1-year follow-up period. We used logistic regression to identify the factors associated with the locations of initial and subsequent stroke care. Of the 6,699 patients studied, 76% received their initial care at a Medicare-reimbursed hospital ("Medicare-first" patients) and 24% at a VA hospital ("VA-first" patients). Patients who were white, married, female, or living farther from the VA were more likely to be Medicare-first patients. During the follow-up period, Medicare-first patients were more likely not only to seek further care but also to use the dual systems than were VA-first patients (71% vs 49%, respectively). The high rates of dual-system use highlight the need for care coordination across systems to address issues of care duplication and continuity.

Fatigue in the elderly population.

Fatigue in the elderly population is a complex phenomenon. Although a number of factors contributing to the fatigue have been identified, its basic mechanism remains elusive. Additional research on prevalence, identification, diagnosis, severity of fatigue, and associated factors and the role of exercise as an effective treatment modality could lead to a better understanding of the causal factors.
