Delirium describes a syndrome of acute brain dysfunction with severe consequences on patient outcomes, medical cost, morbidity, and mortality. It represents a final common pathway of numerous pathophysiologic disturbances disrupting cerebral homeostasis. The diagnosis is predicated on recognition of the clinical features of the syndrome through ongoing clinical assessment. Early identification can be aided by routine screening, particularly in high-risk populations. Evaluation and management are continuous and simultaneous processes involving a multidisciplinary care team including child psychiatry consultation. Prevention, early identification and management are critical in alleviating symptoms, improving outcomes, and reducing distress for patients, families, and care teams. This review highlights our current understanding regarding pediatric delirium, its mechanisms, clinical manifestations, detection and management. 相似文献

BACKGROUND AND OBJECTIVES: To analyze the predictors and outcomes of recurrent disease in patients with epithelial ovarian carcinoma (EOC) after a negative second look laparotomy (SLL). METHODS: One hundred nine EOC patients with a negative SLL treated at Hacettepe Hospital were retrospectively analyzed. RESULTS: Of these patients, 70 (64.2%) had no evidence of disease during follow up while remaining 39 (35.8%) had recurrence. Majority of the recurrences (82.1%) were detected within the initial 2 years of the SLL procedure. Multivariate analysis revealed stage and grade of the disease to be the significant predictors for the recurrent disease (P < 0.01 and P = 0.025, respectively). A second analysis with respect to initial metastatic sites revealed omental metastatis was significantly associated with recurrent disease (P < 0.001). Survival of patients with a recurrent disease was significantly poorer and dropped abruptly once a recurrence is developed. CONCLUSIONS: Patients with initial omental metastasis, advanced stage and high grade tumors have highest risk for developing recurrences after a (-) SLL. Most of the recurrences develop during the initial 2 years following the (-) SLL and survival drops to less than 2 years once a recurrence is found. 相似文献

Background: To evaluate gynecologic oncologists’ trends and attitudes towards the use of Minimally invasive surgery (MIS) in active period of the COVID-19 pandemic in Turkey. Methods: Online national survey sent to members of Turkish Endoscopy Platform consisting of six sections and 45 questions between the dates 1-15 June 2020 in Turkey to explore their surgical practice during the pandemic in three hospital types: Education and research hospital/university hospital, state hospital and private Hospital. Participants were gynecologic oncologists who are members of Turkish Endoscopy Platform. Results: Fifty-eight percent of participants canceled all operations except for cancer surgeries and emergent operations. About a quarter of participants (28%) continued to operate laparoscopically and/or robotically. For the evaluation of the suspected adnexial mass (SAM) 64% used laparotomy and only 13 % operated by laparoscopy (L/S). For the management of low-risk early-stage endometrial cancer only fifth of the participants preferred to perform L/S. For endometrial cancer with high-intermediate risk factors more than half of participants preferred complete staging with laparotomy. For advanced stage ovarian cancer, one-fifth of the participants preferred to perform an explorative laparotomy, whilst 15 % preferred diagnostic laparoscopy to triage the patients for either NACT or cytoreductive surgery. On the contrary 41 % of participants chose to have cytology by paracentesis for neo-adjuvant chemotherapy (NACT). Gynecologic oncologists with >10 years L/S experience used MIS more for SAM. Furthermore, experienced surgeons used L/S more for endometrial cancer patients. In busy COVID hospitals, more participants preferred laparotomy over L/S. Conclusion: Use of MIS decreased during the pandemic in Turkey. More experienced surgeons continued to perform MIS. Surgical treatment was the preferred approach for SAM, early-stage endometrial cancer. However, NACT was more popular compared to radical surgery. 相似文献

Providing health services with the greatest possible value to patients and society given the constraints imposed by patient characteristics, health care system characteristics, budgets, and so forth relies heavily on the design of structures and processes. Such problems are complex and require a rigorous and systematic approach to identify the best solution. Constrained optimization is a set of methods designed to identify efficiently and systematically the best solution (the optimal solution) to a problem characterized by a number of potential solutions in the presence of identified constraints. This report identifies 1) key concepts and the main steps in building an optimization model; 2) the types of problems for which optimal solutions can be determined in real-world health applications; and 3) the appropriate optimization methods for these problems. We first present a simple graphical model based on the treatment of “regular” and “severe” patients, which maximizes the overall health benefit subject to time and budget constraints. We then relate it back to how optimization is relevant in health services research for addressing present day challenges. We also explain how these mathematical optimization methods relate to simulation methods, to standard health economic analysis techniques, and to the emergent fields of analytics and machine learning. 相似文献

We present imaging findings of aberrant left gastric vein (ALGV) and associated pseudolesions and mimickers including metastases and focal nodular hyperplasia. ALGV is formed due to interrupted involution of anastomotic omental veins, and it can drain into left portal vein or segments II and III of the liver as third inflow. Focal fat, focal fat sparing, and perfusion changes can be seen due to the presence of ALGV, which can mimic metastasis in cancer patients. ALGV may also serve as a pathway for direct tumor spread into the liver in patients with gastric cancer. Magnetic resonance imaging can be used as a problem solving tool in the presence of equivocal findings on ultrasonography and computed tomography.Pseudolesions of the liver are a well-known issue and have been reported in the literature. These pseudolesions are caused by aberrant hepatopedal venous flow other than portal venous system, also known as third inflow. Third inflow is most commonly due to aberrant right gastric, paraumbilical, and cholecystic veins (1–3). Pseudolesions caused by aberrant left gastric vein (ALGV) are considered to be a more rare entity (4).The purpose of this study is to illustrate ALGV drainage into the liver and associated pseudolesions of segments II and III of the liver. In addition, we illustrate imaging findings of the mimickers of these pseudolesions. 相似文献
