Outcome for children with cyclical vomiting syndrome.

OBJECTIVE: Cyclical vomiting syndrome (CVS) is a disorder that carries a significant burden of disease for children and their families. The aim of this study was to examine the outcome of a group of children diagnosed with CVS from 1993 to 2003. METHODS: Children diagnosed with CVS over a 10-year period were identified and a review of the clinical records was carried out to define demographic features and the spectrum of disease at presentation. The patient's parent was contacted to establish the child's current well-being. Ethical approval for the study was obtained. RESULTS: Fifty one children were diagnosed with CVS and 41 agreed to participate in follow-up. Mean age was 5.8 (SD 3.3) years at onset of CVS, 8.2 (SD 3.5) years at diagnosis, and 12.8 (SD 4.8) years at follow-up. Vomiting had resolved at the time of follow-up in 25/41 (61%) children. Sixteen of 41 (39%) children reported resolution of symptoms either immediately or within weeks of diagnosis. However, a large number of children from the group whose vomiting resolved and the group that were still vomiting continued to have somatic symptoms, with 42% of children suffering regular headaches and 37% having abdominal pain. 32 (78%) parents felt that the provision of a positive diagnosis and information made a significant impact on the severity of vomiting. CONCLUSIONS: While 60% of children with CVS have resolution of symptoms, a significant proportion of both those in whom symptoms have resolved and those in whom vomiting persists continue to suffer from other somatic symptoms.     

Developing information literacy: a key to evidence-based nursing

This report describes the evaluation of a curriculum-integrated programme designed to help students develop an awareness of the nursing literature, the skills to locate and retrieve it, and skills required in its evaluation; in other words'information literacy'. Positive changes in student performance on objective measures of information-literacy skills were revealed as well as a significant increase in the levels of confidence of the student in performing those skills. Students who had undertaken the information-literacy programme ('programme' students) performed better on a range of objective measures of information literacy, as well as reporting higher levels of confidence in these skills, than students who had not participated in the programme ('non-programme' students). Evaluation of this programme provides evidence of the potential usefulness of a curriculum-integrated approach for the development of information-literacy skills within nursing education. With these underlying skills, students will be better equipped to consolidate and extend their key information-literacy skills to include research appreciation and application. These are vital for effective lifelong learning and a prerequisite to evidence-based practice.     

Staff perceptions of leadership during implementation of task-shifting in three surgical units

Background Registered nurses are difficult to recruit and retain. Task shifting, which involves reallocation of delegation, can reduce demand for registered nurses. Effective leadership is needed for successful task shifting. Objective This study explored leadership styles of three surgical nurse unit managers. Staff completed surveys before and after the implementation of task shifting. Task shifting involved the introduction of endorsed enrolled nurses (licensed nurses who must practise under registered nurse supervision) to better utilize registered nurses. Methods Implementation of task shifting occurred over 4 months in a 700-bed tertiary hospital, in southeast Queensland, Australia. A facilitator assisted nurse unit managers during implementation. The impact was assessed by comparison of data before (n = 49) and after (n = 72) task shifting from registered nurses and endorsed enrolled nurses (n = 121) who completed the Ward Organization Features Survey. Results Significant differences in leadership and staff organization subscales across the settings suggest that how change involving task shifting is implemented influences nurses’ opinions of leadership. Conclusion Leadership behaviours of nurse unit managers is a key consideration in managing change such as task shifting. Implications for nursing management Consistent and clear messages from leaders about practice change are viewed positively by nursing staff. In the short term, incremental change possibly results in staff maintaining confidence in leadership.     

Post-positivistic critical multiplism: a beginning dialogue

Following the recognition that logical positivism was no longer tenable in modern science, post-positivism and its research methodology, critical multiplism, emerged and offered a new way of thinking about science. Though not a panacea, critical multiplism, in which methodological pluralism is advocated, offers a way around the debate of which conception of science is appropriate for nursing and, as such, poses advantages for nursing scientific knowledge development.     

Phenomenology as research method or substantive metaphysics? An overview of phenomenology's uses in nursing

In exploring phenomenological literature, it is evident that the term ‘phenomenology’ holds rather different meanings depending upon the context. Phenomenology has been described as both a philosophical movement and an approach to human science research. The phenomenology of Husserl, Heidegger, Gadamer, and Merleau‐Ponty was philosophical in nature and not intended to provide rules or procedures for conducting research. The Canadian social scientist, van Manen, however, introduced specific guidelines for conducting human science research, which is rooted in hermeneutic phenomenology and this particular method has been employed in professional disciplines such as education, nursing, clinical psychology, and law. The purpose of this paper is to explore the difference between the phenomenological method as described by van Manen and that of other philosophers such as Husserl, Heidegger, Gadamer, and Merleau‐Ponty. In so doing, the author aims to address the blurred boundaries of phenomenology as a research method and as a philosophical movement and highlight the influence of these blurred boundaries on nursing knowledge development.     

Experience of intravenous sedation for pediatric gastrointestinal endoscopy in a large tertiary referral center in a developing country

Background: The aim of this study was to evaluate the clinical efficacy of intravenous sedation for pediatric gastrointestinal endoscopy (GIE) at a tertiary care teaching hospital in a developing country. Methods: We undertook a retrospective review of the sedation service records of pediatric patients who underwent GIE. All endoscopies were performed by a pediatric gastroenterologist. All of the sedation was administered by staff anesthesiologist or anesthetic personnel in the gastroenterology procedure room. Results: Sedation was provided for 222 procedures in 214 patients ranged in age from younger than 1 to 17 years and in weight from 2.7 to 80.0 kg. Intravenous sedation was provided in 176 patients (82.2%). Of these patients, 185 procedures were performed and reviewed, with 152 (82.2%) procedures were esophagogastroduodenoscopy (EGD) alone, 14 (7.6%) procedures were colonoscopy alone, 18 (9.7%) procedures were EGD and colonoscopy, and one procedure was endoscopic ultrasonography (EUS). Most common indications of the procedure were screening for esophageal varices (25.2%), abdominal pain (15.9%), history of upper gastrointestinal hemorrhage (13.6%), and unexplained anemia (10.3%). The majority of preanesthetic problems were hematologic disease, anemia (38.2%); liver disease, cirrhosis (13.5%); and electrolyte imbalance (13.5%). Propofol (94.0%), fentanyl (87.0%), and midazolam (67.8%) were frequently used. The mean dose of propofol was 7.8 ± 4.1 mg·kg^?1·h^?1, fentanyl 2.3 ± 1.1 mcg·kg^?1·h^?1, and midazolam 0.1 ± 0.1 mg·kg^?1·h^?1. Most of them were used in combination. The combination of propofol, fentanyl, and midazolam was commonly employed (46.4%). The mean sedation time of all procedures was 28.2 min and was different according to procedure type. Complications occurred infrequently (13.5%) and were medication or airway related. All complications were easily treated, with no adverse sequelae. Intravenous sedation was successful except for one patient who required general anesthesia. However, all procedures were completed successfully. Conclusions: In the setting of the developing country, intravenous sedation for pediatric GIE by trained anesthetic personnel with appropriate monitoring was safe and effective. Serious adverse events were rare in our population.

Lipohemarthrosis of the knee: a review of recent experiences

The radiographs of 268 patients with knee trauma were retrospectively reviewed. In 15 patients with intraarticular fracture, the images demonstrated fat-fluid levels. In 28 other patients with intraarticular fracture, only joint effusion without a fat-fluid level was depicted. The presence of a fat-fluid level in the knee indicated fracture in all patients in whom it was seen. The absence of such a level, however, did not exclude intraarticular fracture.
