Child abuse is the leading cause of serious traumatic brain injury (TBI) in infants and young children (Billmire & Myers, 1985; Bruce & Zimmerman, 1989). The incidence of serious or fatal inflicted traumatic brain injury (iTBI) in children < 1 year of age is approximately 1 in 3,300 ( Keenan et al., 2003); since many cases of iTBI are of mild or moderate severity, the incidence is probably significantly higher. Even at an incidence of 1 in 3,300, iTBI is as common as the incidence of cystic fibrosis (CF), the most common genetic recessive disease in the Caucasian population. Proper diagnosis of iTBI is difficult even for experienced and astute physicians because its presentation can be subtle and important historical data are often lacking. As a result, misdiagnosis is common and can have catastrophic medical consequences for patients and significant financial consequences for society ( Ewing-Cobbs et al., 1998; Jenny, Hymel, Pitzen, Reinert, & Hay, 1999). Unlike CF for which there are several well established screening tests, there are currently no diagnostic adjuncts to help physicians screen for possible iTBI. 相似文献

Objective
The aim of this study was to evaluate the safety and efficiency of enucleation (EU) for proximal pancreatic non-invasive neoplasms.Methods
Patients with solitary non-invasive neoplasms in the proximal pancreas from January 1998 to April 2014 at the Second Affiliated Hospital of Zhejiang University, Hangzhou, China were included. Different operations and outcomes were analyzed.Results
A total of 123 patients were enrolled. Forty patients (32.5%) underwent EU including 18 patients who had tumors close to the main pancreatic duct (MPD). Sixty-one patients (49.6%) had pancreaticoduodenectomy (PD) performed and 22 (17.9%) underwent central pancreatectomy (CP). Pathological outcomes included neuroendocrine tumors, cystic lesions, and solid pseudopapillary tumors. Operation time, intra-operative blood loss, and duration of hospital stay were significantly reduced in the EU group. PD was associated with the greatest complication rate (55.7%), followed by EU (50%) and CP (40.9%), though the pancreatic fistula rate after EU was the highest (50%), especially in patients with tumors larger than 3 cm and tumors close to the MPD. EU had advantages in the preservation of pancreatic parenchyma and endocrine and exocrine function.Conclusions
EU can be carried out safely and effectively for tumors in the proximal pancreas with improved outcomes compared with standard resections, even if the tumor is larger than 3 cm and close to the MPD.8.
Anxiety is now recognized as one of the most common co-occurring conditions in youth diagnosed with autism spectrum disorder (ASD). Despite the prevalence of this comorbid condition, accurate assessment and diagnosis of anxiety in ASD has proven difficult. This paper will address the considerable research literature on assessing anxiety in youth with ASD, including difficulties related to assessment and differential diagnosis. In addition, this paper will describe relevant tools and methods for assessing anxiety in this complex population. 相似文献

Schools in Australia are required to promote equitable access to education and provide support services to students with chronic health conditions (CHCs). This qualitative study was conducted to explore stakeholders’ experiences and perceptions regarding school-based support. In-depth interviews were conducted with 38 parents of upper secondary school students with cystic fibrosis, anorexia nervosa or cancer (which were illustrative of different types of severe congenital, mental health or somatic CHCs). This enabled comparison of findings to determine whether there were any patterns in perceptions and experiences that were tied to the different CHCs. Data were analysed using a modified grounded theory approach to identify themes. Even though analysis indicated that all cohorts of parents viewed informed educators as best placed to provide tailored school-based support, major cohort differences were reported in parental experiences of school-based support as well as parental diagnosis disclosure behaviour. This latter finding was associated with cohort-related perceptions of risk to their adolescent child. Barriers to school-based support were perceived as varying by condition, the advocacy experience of parents and the nature of health service supports. Taking these findings into account, modification of current policies and practices within education and health sectors may lead to more equitable educational outcomes. 相似文献

The SCOR (Supply Chain Operations Reference) Model Supply Chain Classroom Simulation is an in‐class experiential learning activity that helps students develop a holistic understanding of the processes and challenges of supply chain management. The simulation has broader learning objectives than other supply chain related activities such as the Beer Game. Competing supply chains work to produce and sell two products, each experiencing differential demand. Seasonal demand, time delays, quality defects, and disruptions offer complexities that are part of actual supply chain management. The behavioral dynamics of collaboration between various functional nodes is illustrated through students’ interactions as they try to achieve their role's objectives. Through their decisions and actions, students develop a practical understanding of the processes and complexities of supply chain management. The classroom simulation actively engages students, and has been used successfully in multiple courses at the undergraduate and graduate levels at multiple universities and by a major corporation during a manager training session. Assessments indicate that the simulation is an effective experiential learning activity. While it offers learning outcome flexibility, common debrief themes are SCOR model processes, supply chain relationships, information flow, seasonal demand, quality defects, reverse logistics, and supply chain disruptions. 相似文献

Child maltreatment research varies considerably in how maltreatment is measured. Although researchers have advocated for improvements in maltreatment assessment, a first step is a clear understanding of the status on how the field operationalizes maltreatment. The current paper sought to achieve this goal through reviewing research on child maltreatment over a recent 10-year span to identify trends in maltreatment assessment and operationalization. Information on maltreatment measurement was extracted from 338 articles across three major journals devoted to publishing research on child maltreatment. Among the various definitional dimensions of maltreatment, type was the most common way maltreatment was operationalized, followed by severity, frequency, and chronicity, a stable trend across the 10-year span of review. The results indicated that the majority of studies measured maltreatment as consisting of multiple types, although some studies focused on one type of maltreatment as the indicator of child maltreatment. Further, the most common assessment method was the administration of a questionnaire or the combination of two questionnaires with the second most common being summaries from case file review. Recommendations for future research are discussed. 相似文献

The diagnosis of extra-pulmonary tuberculosis(TB) seems relatively difficult due to the absence of specific symptoms and signs in patients on peritoneal dialysis or hemodialysis.We report four cases of extra-pulmonary tuberculosis on dialysis,with two cases on peritoneal dialysis and two cases on hemodialysis.The presentations,therapy,and outcomes of TB infection in these patients were reviewed.Otherwise,the English literature published in the PubMed database associating extra-pulmonary tuberculosis on dialysis over the last three decades is reviewed.A total of 61 studies containing 70 cases were included.The most common primary disease was diabetic nephropathy(22.86%,16/70).The peritoneum(31.42%,22/70),bone(21.42%,15/70),and lymph node(20%,14/70) were the most frequently infected.Single organ infection was common(90%,63/70).Fever(58.57%,41/70),pain(35.71%,25/70),and enlarged lymph node(20%,14/70) were the most common symptoms.Biopsy(67.14%,47/70) and culture(40%,28/70) provided most reliable methods for clear diagnosis of tuberculosis.The combined treatment of isoniazid,rifampicin,pyrazinamide,and ethambutol(44.29%,31/70) was the most common therapy.The majority of patients improved(82.86%,58/70);however,12 cases got worse(17.14%),with 10 of them dying(14.29%).Physicians should be aware of the non-specific symptoms and location of infection,and consider tuberculosis in their differential diagnoses in dialysis patients presenting with symptoms such as fever,pain,and weight loss. 相似文献

Mounting evidence indicates that students of color are more likely than their white peers to receive exclusionary discipline (out-of-school suspensions and expulsions), but alleviating these disparities requires an understanding of what drives them. In this study, we use seven years of student- and infraction-level data from every public school in Arkansas to examine disproportionalities within and across districts and schools. Prior analyses of the same data found that black students are more likely to receive exclusionary discipline than their white peers, even after controlling for the nature and number of disciplinary referrals, but most of the differences occur between schools, rather than within. We build on these findings in two ways: (a) by estimating the racial disparities in the likelihood of referral for particular infraction types and (b) by estimating whether the racial disproportionalities in the use of exclusionary discipline, after controlling for reported behavior, differ according to the types of infractions reported. We find that for common, subjective infractions, black students are at a higher risk of referral and at a higher risk of exclusionary discipline, conditional on referral. In addition, disparities appear to be driven by differences across school districts (rather than within). These findings have important implications for designing and targeting discipline reforms where they are needed most. 相似文献

Differential Treatment of Siblings: Interview and Diary Analyses Comparing Two Family Contexts 总被引：4，自引：0，他引：4
We assessed parental differential treatment of siblings (maternal time, affection, discipline) in normal and high-risk families. Differential treatment was measured using home interviews, nightly phone ratings, and daily diaries tracking how mothers spent their time. Subjects were 40 mothers of toddlers (average age 2 years) and preschoolers (average age 4 1/2 years): half were caring for a younger child with a chronic illness (i.e., cystic fibrosis), and half were caring for two healthy children. Little evidence of parental differential treatment was found in the home or phone interview data. However, on the diary variables, both quantitative and qualitative differences in parental treatment were found in cystic fibrosis (CF) versus comparison families. Specifically, mothers spent more individual time with younger, chronically ill children in play and mealtime activities than with their older, healthy siblings. Further, mothers in the CF group rated time spent with older children as significantly more negative than time spent with younger children. Convergence between measures of differential treatment and advantages of using a high-risk comparison approach are discussed. 相似文献
