Intra-abdominal hypertension can be classified as either primary or secondary. Primary intra-abdominal hypertension is often associated through trauma or diseases of the abdominopelvic region such as pancreatitis or abdominal surgery, while secondary intra-abdominal hypertension is the result of extra-abdominal causes such as sepsis or burns. The critically ill patient offers some challenges in monitoring in particular secondaryintra-abdominal hypertension because of the effects of fluid resuscitation, the use of inotropes and positive pressure ventilation...

The Dementia with Lewy Bodies (DLB) Consortium has refined its recommendations about the clinical and pathologic diagnosis of DLB, updating the previous report, which has been in widespread use for the last decade. The revised DLB consensus criteria now distinguish clearly between clinical features and diagnostic biomarkers, and give guidance about optimal methods to establish and interpret these. Substantial new information has been incorporated about previously reported aspects of DLB, with increased diagnostic weighting given to REM sleep behavior disorder and (123)iodine-metaiodobenzylguanidine (MIBG) myocardial scintigraphy...

Although pain management is a major challenge for clinicians, appropriate pain control is the foundation of efficacious burn care from initial injury to long-term recovery. The very treatments designed to treat burn wounds may inflict more pain than the initial injury itself, making it the clinician's duty to embrace a multimodal treatment approach to burn pain. Vigilant pain assessment, meaningful understanding of the pathophysiology and pharmacologic considerations across different phases of burn injury, and compassionate attention to anxiety and other psychosocial contributors to pain will enhance the clinician's ability to provide excellent pain management...

The classic determinants of mortality from severe burn injury are age, size of injury, delays of resuscitation, and the presence of inhalation injury. Of the major determinants of mortality, inhalation injury remains one of the most challenging injuries for burn care providers. Patients with inhalation injury are at increased risk for pneumonia (the leading cause of death) and multisystem organ failure. There is no consensus among leading burn care centers in the management of inhalation injury. This article outlines the current treatment algorithms and the evidence of their efficacy...

This article reviews the pathophysiology of large burn injury and the extreme fluid shifts that occur in the hours and days after this event. The authors focus on acute fluid management, monitoring of hemodynamic status, and end points of resuscitation. Understanding the need and causes for fluid resuscitation after burn injury helps the clinician develop an effective plan to balance the competing goals of normalized tissue perfusion and limited tissue edema. Thoughtful, individualized treatment is the best answer and the most effective compromise...

In humans, regeneration of the corneal epithelium is regulated by the stem cell reservoir of the limbus. After extensive limbal damage, e.g., by inflammation, thermal burn or chemical injury, limbal stem cell deficiency leading to vascularization and opacification of the cornea and resulting in vision loss, may develop. Several techniques of autologous and allogenic stem cell transplantation have been established. The limbus can be restored by transplantation of whole limbal grafts, small limbal biopsies or by ex vivo-expanded limbal cells...

Objective To review the clinical entity of primary burning mouth syndrome (BMS), its pathophysiological mechanisms, accurate new diagnostic methods and evidence-based treatment options, and to describe novel lines for future research regarding aetiology, pathophysiology, and new therapeutic strategies. Description Primary BMS is a chronic neuropathic intraoral pain condition that despite typical symptoms lacks clear clinical signs of neuropathic involvement. With advanced diagnostic methods, such as quantitative sensory testing of small somatosensory and taste afferents, neurophysiological recordings of the trigeminal system, and peripheral nerve blocks, most BMS patients can be classified into the peripheral or central type of neuropathic pain...

BACKGROUND: ARDS is characterized by decreased functional residual capacity (FRC), heterogeneous lung injury, and severe hypoxemia. Tidal ventilation is preferentially distributed to ventilated alveoli. Aerosolized prostaglandin I2 exploits this pathophysiology by inducing local vasodilation, thereby increasing ventilation-perfusion matching and reducing hypoxemia. Therefore, aerosolized prostaglandin I2 efficacy may depend upon FRC. Both PaO2 /FIO2 and compliance of the respiratory system (CRS) are indirect signifiers of FRC and thus may partly determine the response to aerosolized prostaglandin I2...

Alzheimer's disease (AD) may have heterogeneous pathophysiological underpinnings, with risk factors including apolipoprotein rmvarep4 (APOE4) genotype and insulin resistance. We hypothesized that distinct phenotypes exist within AD. We examined APOE4 and metabolic biomarkers in 338 subjects (n = 213 nondemented (ND), n = 125 AD). We further characterized steady state free fatty acid (FFA) levels in a subset of 45 participants who had also participated in a hyperinsulinemic-euglycemic clamp. Insulin resistance (HOMA-IR) was elevated in AD versus ND (p = 0...

Complex regional pain syndrome (CRPS) is one of the most challenging chronic pain conditions and is characterized by burning pain, allodynia, hyperalgesia, autonomic changes, trophic changes, edema, and functional loss involving mainly the extremities. Until recently, very few reports have been published concerning CRPS involving the orofacial area. We report on a 50-year-old female patient who presented with unbearable pain in all of her teeth and hypersensitivity of the facial skin. She also reported intractable pain in both extremities accompanied by temperature changes and orofacial pain that increased when the other pains were aggravated...

Increased resting metabolic rate (hypermetabolism) and skeletal muscle wasting are hallmarks of the pathophysiological stress response to severe burn trauma. However, whether these two responses occur independently in burn patients or are in fact related remains unclear. In light of recent evidence demonstrating that increased proteolysis in skeletal muscle of burned patients is accompanied by mitochondrial hypermetabolism, oxidative stress, and protein damage; in this article, we discuss the evidence for a role for the mitochondrion in skeletal muscle wasting following severe burn trauma...

Electrical injuries are a commonly encountered hazard in both the home and workplace. However, clinicians are often uncomfortable when faced with the patient who presents with an electric shock due to sparse literature and lack of systematic recommendations on this topic. Electrical injuries can range from minor skin burns to life threatening internal organ damage. A thorough clinical assessment to ascertain the path of current through the body and possible internal injury is essential. The main concern in an apparently stable individual after an electric shock is the potential for delayed occurrence of cardiac arrhythmias which will require monitoring in the intensive care setting...

Trauma-induced acute kidney injury (AKI), such as after hemorrhagic shock (HS) or burn, remains a significant problem in the intensive care unit and is associated with increased mortality. The pathophysiology that drives AKI post-trauma is multi factorial, and includes both inflammatory and metabolic alterations. Identifying the systemic profile that contributes to AKI is crucial not only for early diagnosis, but also for identifying treatments that improve kidney function and maintaining long-term patient health...

Sepsis remains a major cause of death in severe burns. The effect of sepsis management is influenced by its complicated pathophysiologic changes. In order to improve the outcome of burn sepsis, the predisposing factor of sepsis after burn analyzed by advanced technology, the early prevention, antibiotics therapy, and combined treatment in severe burns with sepsis are discussed using the concept of holistic integrative medicine.

Inhalation injury commonly accompanies thermal injury, increasing the likelihood of mortality and multiple organ dysfunction (MOD). Large animal models have given important insight into the pathophysiology of this injury; however recapitulating late MOD has remained difficult. The current report describes experiments using a smoke inhalation and burn model, with follow-up of ambulatory swine for 14days with bronchoscopy, CT scanning, and bronchoalveolar lavage fluid (BALF)/blood collection. Clinically, animals cleared airway damage in the first several days after-injury...
