INTRODUCTION: Reversible edema is a part of any radiofrequency ablation but its relationship with contact force is unknown. The goal of this study was to characterize through histology and MRI, acute and chronic ablation lesions and reversible edema with contact force. METHODS AND RESULTS: In a canine model (n = 14), chronic ventricular lesions were created with a 3.5 mm tip ThermoCool SmartTouch (Biosense Webster) catheter at 25W or 40W for 30 sec. Repeat ablation was performed after 3 months to create a second set of lesions (acute)...

Sympathetic Crashing Acute Pulmonary Edema (SCAPE), or flash pulmonary edema, is the extreme end of the acute pulmonary edema spectrum. A sympathetic surge occurs as a result of decreased systemic perfusion resulting in further increases in afterload, causing the patient to decompensate. Patients can decompensate quickly, therefore patients require rapid interventions. The use of high-dose nitroglycerin (HDN) has been a topic of interest as it is believed to achieve preload and afterload reduction. However, its use continues to be controversial due to concerns of drug induced hypotension, syncope or paresthesia...

The purpose of this study was a toxicological interpretation of exposure to chlorine with unusual course. Medical, clinical and court records, as well as reviews of the literature, served as the basis for this interpretation. The first case of poisoning concerns a 52-year-old man who for a short time (probably several hours), during the industrial cleaning of facilities with sodium hypochlorite, was exposed to chlorine in a presumed high concentration. The man was obese and suffered from hypertension and moderate atherosclerosis, and therefore could be more susceptible to the toxic effects of chlorine...

Objective: Patients with traumatic acute subdural hematoma (ASDH) often require surgical treatment. Among patients who primarily underwent craniotomy for the removal of hematoma, some consequently developed aggressive intracranial hypertension and brain edema, and required secondary decompressive craniectomy (DC). To avoid reoperation, we investigated factors which predict the requirement of DC by comparing groups of ASDH patients who did and did not require DC after craniotomy. Methods: The 129 patients with ASDH who underwent craniotomy from September 2007 to September 2017 were reviewed...

Acute ischemic stroke is a common cause of morbidity and mortality worldwide. Thrombolysis with recombinant tissue plasminogen activator and endovascular thrombectomy are the main revascularization therapies for acute ischemic stroke. However, ischemia-reperfusion injury after revascularization therapy can result in worsening outcomes. Among all possible pathological mechanisms of ischemia-reperfusion injury, free radical damage (mainly oxidative/nitrosative stress injury) has been found to play a key role in the process...

Important differences in the biology of focal and diffuse traumatic brain injury (TBI) subtypes may result in unique pathophysiological responses to shared molecular mechanisms. Interleukin-1 (IL-1) signaling has been tested as a potential therapeutic target in preclinical models of cerebral contusion and diffuse TBI, and in a phase II clinical trial, but no published studies have examined IL-1 signaling in an impact/acceleration closed head injury (CHI) model. We hypothesized that genetic deletion of IL-1 receptor-1 (IL-1R1 KO) would be beneficial in focal (contusion) and CHI in mice...

Intestinal ischemia and reperfusion (II/R) injury often triggers severe injury in remote organs, with the lungs being considered the main target. Excessive elevation of proinflammatory cytokines is a major contributor in the occurrence and development of II/R‑induced acute lung injury (ALI). Therefore, the present study aimed to investigate whether blocking tumor necrosis factor‑α (TNF‑α) expression could protect the lungs from injury following II/R, and to explore the possible underlying mechanism involving interleukin‑10 (IL‑10)...

Acute Charcot neuroarthropathy of the foot and ankle is often difficult to diagnose because of limited findings in the patient history, physical examination, imaging, and laboratory studies. Delay in treatment results in the development of rigid foot and ankle deformities, increasing the risk of ulceration, infection, and major lower extremity amputation. Acute Charcot neuroarthropathy should be suspected in any patient 40 years or older with obesity and peripheral neuropathy who presents with an acutely swollen foot following minimal or no recalled trauma and who reports minimal to no pain, particularly if radiography and laboratory markers of infection are normal...

A 54-year-old man with grade 2 rectal neuroendocrine tumor and hepatic, pancreatic, and bone metastases was treated with Lu-DOTATATE as second-line therapy, after failure of somatostatin analogues. Two weeks after the first injection, he presented at the emergency department with acute pancreatitis. We hypothesized that this unusual adverse event, never been reported so far, was the result of acute tumor irradiation after PRRT, leading to peritumoral inflammation and edema with obstruction of an accessory pancreatic duct...

BACKGROUND Hyperglycemic crises can cause severe neurologic impairment. One of the most dreaded consequences of hyperglycemic crises is cerebral edema, a rare complication seen during the treatment of hyperglycemic crises resulting from overly-aggressive fluid resuscitation and rapid correction of hyperglycemia and hyperosmolarity. CASE REPORT We present a case of profound hyperglycemic crisis with blood glucose greater than 2000 mg/dL, complicated by the development of new neurologic deficits after rapid correction of hyperglycemia...

BACKGROUND: Acute neurological insults caused by infection, systemic inflammation, ischemia, or traumatic injury are often associated with breakdown of the blood-brain barrier (BBB) followed by infiltration of peripheral immune cells, cytotoxic proteins, and water. BBB breakdown and extravasation of these peripheral components into the brain parenchyma result in inflammation, oxidative stress, edema, excitotoxicity, and neurodegeneration. These downstream consequences of BBB dysfunction can drive pathophysiological processes and play a substantial role in the morbidity and mortality of acute and chronic neurological insults, and contribute to long-term sequelae...

Sex dimorphism has been demonstrated after experimental intracerebral hemorrhage (ICH). Decreased mortality and improved neurobehavioral outcomes occur in female compared to male mice after intrastriatal autologous blood or collagenase injection. Sex-specific differences in post-ICH gene and protein expression may provide mechanistic insight into this phenomenon. Ten- to 12-week-old C57BL/6 male (M) and female in high estrous state (HE-F) underwent left intrastriatal collagenase injection. We assessed neurobehavioral outcomes over the first 30 days, hematoma volume and cerebral edema evolution over the first 24 h, and transcriptomic gene and protein expression at pre-selected time points during the acute phase of injury...
