LITT (Laser interstitial thermal therapy) is a stereotactic-guided minimally invasive ablating technique that involves generating high temperatures thus leading to tissue coagulation, necrosis, and cellular apoptosis (1-3). LITT was initially described by Brown et al in 1983, for the treatment of tumors (5). Later, Sugiyama et al described the utility of this modality in the management of deep-seated brain tumors (6). The concept of using heat energy to treat tumors has evolved to a precise and…

When organ tissues undergo coagulative necrosis, the appearance of the organ will remain the same but the color will change. Pale appearance is due to a lack of blood supply where red appearance is due to damaged blood vessels. Liquefactgive necrosis is where tissue breaks down to a liquid form, which will have an appearance in the organ as a cystic space or an abscess. Caseous necrosis is a combination of both coagulative and liquefactive necrosis in which tissue will form a dense substance…

Clinical Action Plan Comparative Report Comparison Both reports listed the routine projections for initial scaphoid investigations and explained the significance of each using similar resources and diagrams. The discussion regarding the blood supply of the scaphoid were also comparable. Similar conclusion was drawn from both reports that MRI is recommended for this case. However, a notable difference between the two reports is that the expert report provided more extensive statistics and…

on whether the cause is pulpitis or pulpal necrosis, there may be a response to vitality, percussion and palpation. Root canal treatment is indicated in these cases. Acute apical abscess Pulp infection and necrosis leads to a rapid severe localised inflammatory reaction, which destroys periapical tissues. The pain is spontaneous and of rapid onset. The affected tooth is extremely painful to percussion and palpation, with possible mobility. Due to necrosis of the pulp there is no pulp vitality.…

I was in Corn Group A for our posters we presented before Fall break. The two disease topics we covered in corn was Goss’s Wilt and Root Rot Pythium. Impact: Between Goss’s Wilt and Root Rot Pythium I believe the Root Rot Pythium has a much greater impact on a Corn plant. There is a much greater impact because the time of infection is at a much earlier time when the plant is just a seedling and has a slim chance of fighting off the necrotrophic disease. When Pythium attacks the seeding through…

Overall survival Mean overall survival (OS) was 13.8 years (median was not reached) with 96% at 3 years, 93% at 5 years, 83% at 10 years and 64% at 15 years after RT. For low-grade meningioma survival rate was 97% at 3 years, 94% at 5 years, 85% at 10 years and 65% at 15 years, for atypical meningioma 91% at 3 years, 86% at 5 years, 62% at 10 years and 50% at 15 years. As expected OS is significantly better for low-grade meningioma (p=.034, Figure 1). Stratified by histology, we compared groups…

019).Ten days after applications, amount of bone neoformation was not different between CS and saline (Table 1). Intergroup comparisons for necrosis, blood clot and inflammation demonstrated that three days after applications, CS and saline caused more necrosis, blood clot and inflammation than samples collected immediately after saline application (necrosis, p = 0,045 and 0,018; blood clot, p = 0,019 and 0,005; inflammation, p = 0,004 and 0,005 for CS and saline, respectively - Tables 2 and…

impairs perfusion, and decreased renal perfusion because of sepsis, vasoactive mediators, drugs, and diagnostic agents (Porth, 2009). Intrarenal failure can be caused by acute tubular necrosis which is when renal function is repressed resulting in death of the epithelial cells in the kidney. Acute tubular necrosis is a result of extended lack of oxygen supply to the kidneys, exposure to nephrotoxic drugs, heavy metals, and organic solvents, intratubular obstructions resulting from hemoglobinuria…

caused by severe sepsis, obstetric complications, or trauma like burns. During these events a reduction in ATP occurs within the cells creating oxygen free radicals as a result of anaerobic metabolism causing cellular injury, swelling and eventually necrosis. This in turn activates the inflammaorty process the release of cytokines causing tubular injury. Furthermore, the transport of sodium and molecules is disrupted by damage to the proximal tubular epithelium (McCance & Huether,…

of the lower extremity (22). Multiple medical comorbidities including but not limited to autoimmune disease, trauma, avascular necrosis (42,52-54), or other idiopathic etiologies contribute to total loss of the talus (40, 43, 61-64). Furthermore, collapse of the talar body as a complication of total ankle arthroplasty (51), talectomy in infection and septic talus necrosis (60) or severe bone defects due to tumor resection (59) may result in the need…
