PURPOSE OF REVIEW: The purpose of this review was to outline the mechanisms and to review recent literature on pulmonary arterial hypertension (PAH) medications in group 5 pulmonary hypertension (PH). RECENT FINDINGS: The first steps in management are to understand the mechanisms and hemodynamic profile and to exclude chronic thromboembolic disease. Recent studies in the past 5 years have found that PAH medications may improve hemodynamics in patients with pre-capillary pulmonary hypertension due to sarcoidosis, pulmonary Langerhans cell histiocytosis, lymphangioleiomyomatosis, and myeloproliferative disorders with dasatinib-induced PH...

The term "neuroinflammation" has been widely used to describe a series of acute or chronic conditions that cause inflammation in the central nervous system (CNS). Neurological damage can be a consequence of direct local injury or, secondary, of systemic or even distant inflammatory processes. In this respect, animal models have been developed to better understand the pathophysiology and, possibly, to evaluate more effective methods of treatment for these disorders. Animal models that promote alterations in blood-brain barrier permeability-the activation of microglia or astrocytes, modifications in neuropeptide expression, oxidative stress, increased apoptosis, release of inflammatory mediators, leukocyte infiltration, and brain edema-are likely to involve neuroinflammation and therefore can serve as useful models for human inflammatory CNS injury...

CLINICAL ISSUE: Neurogenic myopathies are primary diseases of the nervous system, which secondarily result in denervation of the target musculature. The spectrum of potential causes is manifold ranging from acute traumatic injuries and chronic compression to neurodegenerative, inflammatory, metabolic and neoplastic processes. STANDARD DIAGNOSTIC METHODS: The medical history, clinical neurological examination, and electrophysiological tests including electromyography and nerve conduction studies are crucial in diagnosing neuropathic myopathies...

Leflunomide, an immunosuppressive drug approved for the treatment of patients with rheumatoid arthritis, exhibits many mechanisms which may affect the nociceptive processing. Therefore, the present study aimed to evaluate the effect induced by leflunomide on the mechanical allodynia in models of inflammatory and neuropathic pain in mice and investigate mechanisms mediating such effects. Per os (p.o.) administration of leflunomide (25, 50 or 100 mg/kg) inhibited the inflammatory edema and mechanical allodynia induced by intraplantar carrageenan...

Sarcoidosis is one of the leading causes of inflammatory eye disease. Any part of the eye and its adnexal tissues can be involved. Uveitis and optic neuropathy are the main manifestations, which the internists face. This review reports the state of knowledge for these two ocular involvements and proposes an assessment-algorithm for sarcoidosis in patients with suspected sarcoid uveitis. Two groups of patients with sarcoid uveitis can be distinguished: one young and multiethnic group in which ophthalmological findings are various and another group of elderly Caucasian women with mostly chronic posterior uveitis...

Nathaniel T Koutlas, Evan S Dellon
Previous studies have suggested that eosinophilic esophagitis (EoE) progresses from chronic inflammation to fibrostenosis. However, natural history data illustrating this progression in individual patients are lacking. Here, we present 6 patients who progressed from an inflammatory to a fibrostenotic phenotype of EoE in the absence of treatment. At the time of diagnosis, none of the patients had significant evidence of fibrostenosis, but they did have other inflammatory findings of EoE such as edema, linear furrows, or exudates...

REVIEW
Vivek Soi, Jerry Yee
The pathologic consequences of sodium retention in the CKD population can lead to hypertension, edema, and progressive disease. Sodium excess is responsible for increases in oxidative stress, which alters kidney vasculature. As progression of CKD occurs, hyperfiltration by remaining nephrons compensates for an overall decrease in the filtered load of sodium. In the later stages of CKD, compensatory mechanisms are overcome and volume overload ensues. Nephrotic syndrome as it relates to sodium handling involves a different pathophysiology despite a common phenotype...

Breakdown of the blood-retinal barrier (BRB), as occurs in diabetic retinopathy and other chronic retinal diseases, results in vasogenic edema and neural tissue damage, causing vision loss. Vasoinhibins are N-terminal fragments of prolactin that prevent BRB breakdown during diabetes. They modulate the expression of some transient receptor potential (TRP) family members, yet their role in regulating the TRP vanilloid subtype 4 (TRPV4) remains unknown. TRPV4 is a calcium-permeable channel involved in barrier permeability, which blockade has been shown to prevent and resolve pulmonary edema...

We report a case series of unilateral Salter-Harris IV fractures of the proximal radial heads in young female gymnasts. To date, there are no previous reports of such injuries in gymnastics. In all 3 athletes, no significant injury preceded presentation or diagnosis. Radiographs and magnetic resonance imaging showed fractures and associated bone marrow edema of the proximal radial head, respectively. All but 1 was treated nonoperatively with success. Given the lack of acute trauma, lack of large effusion, and good range of motion at presentation, these injuries are believed to be chronic in nature and related to overuse...

Chronic spontaneous urticaria (CSU) is a common skin disorder characterized by daily or almost daily recurring skin edema and flare with itch. Recently, the activation of the blood coagulation cascade has been suggested to be involved in CSU, but the trigger of the coagulation cascade remains unclear. In this article, we review recent understanding of the relationship between the pathogenesis of CSU and extrinsic coagulation reactions. In CSU, vascular endothelial cells and eosinophils may play a role as TF-expressing cells for activating the extrinsic coagulation pathway...

Introduction • Low-level laser therapy (LLLT) is a form of light therapy that triggers biochemical changes within cells. Photons are absorbed by cellular photoreceptors, triggering chemical alterations and potential biochemical benefits to the human body. LLLT has been used in pain management for years and is also known as cold laser therapy, which uses low-frequency continuous laser of typically 600 to 1000 nm wavelength for pain reduction and healing stimulation. Many studies have demonstrated analgesic and anti-inflammatory effects provided by photobiomodulation in both experimental and clinical trials...
