Spinal cord injury (SCI) is a major health problem and is associated with a diversity of neurological symptoms. Pathophysiologically, dysfunction after SCI results from the culmination of tissue damage produced both by the primary insult and a range of secondary injury mechanisms. The application of hypothermia has been demonstrated to be neuroprotective after SCI in both experimental and human studies. The myriad of protective mechanisms of hypothermia include the slowing down of metabolism, decreasing free radical generation, inhibiting excitotoxicity and apoptosis, ameliorating inflammation, preserving the blood spinal cord barrier, inhibiting astrogliosis, promoting angiogenesis, as well as decreasing axonal damage and encouraging neurogenesis. Hypothermia has also been combined with other interventions, such as antioxidants, anesthetics, alkalinization and cell transplantation for additional benefit. Although a large body of work has reported on the effectiveness of hypothermia as a neuroprotective approach after SCI and its application has been translated to the clinic, a number of questions still remain regarding its use, including the identification of hypothermia’s therapeutic window, optimal duration and the most appropriate rewarming rate. In addition, it is necessary to investigate the neuroprotective effect of combining therapeutic hypothermia with other treatment strategies for putative synergies, particularly those involving neurorepair.

Risk assessment is becoming more emphasized in international projects decisions. In this paper, the international project risk assessment starts with the risk classification using the hierarchical risk breakdown structure. Based on the threelevel hierarchical structure, a risk index (R) model is designed to assess the effects of all the risk sections and sub-sections (factors). The effect scores of risk factors are assessed using fuzzy logic approaches, and weights of risk factors and risk sections are determined using AHP method. The risk index (R) performs two functions: evaluate sources of risk and accordingly prioritize international projects.

A 69-year-old man presented with lower urinary tract symptoms and prostate biopsy showed prostate cancer. 18F-Fluciclovine PET/CT revealed abnormal increased radiotracer uptake within the prostate gland, and multiple osseous structures, suspicious for tumoral involvement. Incidentally, an expansile soft tissue density mass arising from sella turcica demonstrated increased radiotracer activity. MRI showed a lobulated enhancing mass centered in the sella and eroding into the sphenoid sinus. The differential diagnosis includes pituitary macroadenoma versus prostate cancer metastasis. The tumor was resected and the pathological diagnosis was pituitary adenoma.
