    The Risk of Intra-abdominal Injuries in Pediatric Patients with Stable Blunt Abdominal Trauma and Negative Abdominal Computed Tomography

    ACADEMIC EMERGENCY MEDICINE, Issue 5 2010
    Jeffrey Hom MD
    Abstract Objectives:, This review examines the prevalence of intra-abdominal injuries (IAI) and the negative predictive value (NPV) of an abdominal computed tomography (CT) in children who present with blunt abdominal trauma. Methods:, MEDLINE, EMBASE, and Cochrane Library databases were searched. Studies were selected if they enrolled children with blunt abdominal trauma from the emergency department (ED) with significant mechanism of injury requiring an abdominal CT. The primary outcome measure was the rate of IAI in patients with negative initial abdominal CT. The secondary outcome measure was the number of laparotomies, angiographic embolizations, or repeat abdominal CTs in those with negative initial abdominal CTs. Results:, Three studies met the inclusion criteria, comprising a total of 2,596 patients. The overall rate of IAI after a negative abdominal CT was 0.19% (95% confidence interval [CI] = 0.08% to 0.44%). The overall NPV of abdominal CT was 99.8% (95% CI = 99.6% to 99.9%). There were five patients (0.19%, 95% CI = 0.08% to 0.45%) who required additional intervention despite their initial negative CTs: one therapeutic laparotomy for bowel rupture, one diagnostic laparotomy for mesenteric hematoma and serosal tear, and three repeat abdominal CTs (one splenic and two renal injuries). None of the patients in the latter group required surgery or blood transfusion. Conclusions:, The rate of IAI after blunt abdominal trauma with negative CT in children is low. Abdominal CT has a high NPV. The review shows that it might be safe to discharge a stable child home after a negative abdominal CT.

    Treatment of New World cutaneous leishmaniasis , a systematic review with a meta-analysis

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2008
    Felipe Francisco Tuon MD
    Background, New World leishmaniasis is an important endemic disease and public health problem in developing countries. The increase in ecologic tourism has extended this problem to developed countries. Few drugs have emerged over the past 50 years, and drug resistance has increased, such that the cure rate is no better than 80% in large studies. Despite these data, there has been no systematic review with a meta-analysis of the therapy used in this important tropical disease. The aim of this study was to determine the best drug management in the treatment of cutaneous leishmaniasis (CL) in Latin America based on the best studies published in the medical literature. Methods, MEDLINE, LILACS, EMBASE, Web of Science, and Cochrane Library databases were searched to identify articles related to CL and therapy. Articles with adequate data on cure and treatment failure, internal and external validity information, and more than four patients in each treatment arm were included. Results, Fifty-four articles met our inclusion criteria and 12 were included in the meta-analysis. Pentavalent antimonials were the most studied drugs, with a total of 1150 patients, achieving a cure rate of 76.5%. The cure rate of pentamidine was similar to that of pentavalent antimonials. Other drugs showed variable results, and all demonstrated an inferior response. Conclusion, Although pentavalent antimonials are the drugs of choice in the treatment of CL, pentamidine showed similar results. Nevertheless, several aspects, such as cost, adverse effects, local experience, and availability of drugs to treat CL, must be considered when determining the best management of this disease, especially in developing countries where resources are scarce.

    Do perineal exercises during pregnancy prevent the development of urinary incontinence?

    INTERNATIONAL JOURNAL OF UROLOGY, Issue 10 2008
    A systematic review
    Objectives: The aim of the current article was to conduct a systematic review of the performance of perineal exercises during pregnancy and their utility in the prevention of urinary incontinence. Methods: Randomized controlled studies (RCT) of a low-risk obstetric population (primiparas or nulliparas) who had done perineal exercises only during pregnancy met the inclusion criteria. Articles published between 1966 and 2007 from periodicals indexed in the LILACS, SCIELO, PubMed/MEDLINE, SCIRUS and Cochrane Library databases were selected, using the following keywords: ,urinary incontinence', ,pregnancy', ,pelvic floor' and ,exercise'. The Jadad scale was applied to assess the internal validity of the RCT and two meta-analysis: one of fixed effects and the other of random effects were carried out with data extracted from the RCT, using the Stata 9.2 statistical software and adopting a significance level of 0.05. Results: Four RCTs with high methodological quality, involving a total of 675 women were included. They indicated that perineal muscle exercise significantly reduced the development of urinary incontinence from 6 weeks to 3 months after delivery (odds ratio = 0.45; confidence interval: 0.3 to 0.66). However, when evaluating this effect during the 34th and 35th gestational week, a meta-analysis showed that the results were not significant (odds ratio = 0.13; confidence interval: 0.00 to 3.77). Conclusion: Pelvic floor muscle exercises may be effective at reducing the development of postpartum urinary incontinence, despite clinical heterogeneity among the RCT. [source]

    Men and health help-seeking behaviour: literature review

    JOURNAL OF ADVANCED NURSING, Issue 6 2005
    Paul M. Galdas BSc RN CertEd
    Aim., This paper reviews the key research literature regarding men's health-related help seeking behaviour. Background., There is a growing body of research in the United States to suggest that men are less likely than women to seek help from health professionals for problems as diverse as depression, substance abuse, physical disabilities and stressful life events. Previous research has revealed that the principle health related issue facing men in the UK is their reluctance to seek access to health services. Method., The investigation of men's health-related help seeking behaviour has great potential for improving both men and women's lives and reducing national health costs through the development of responsive and effective interventions. A search of the literature was conducted using CINAHL, MEDLINE, EMBASE, PsychINFO and the Cochrane Library databases. Results., Studies comparing men and women are inadequate in explaining the processes involved in men's help seeking behaviour. However, the growing body of gender-specific studies highlights a trend of delayed help seeking when they become ill. A prominent theme among white middle class men implicates ,traditional masculine behaviour' as an explanation for delays in seeking help among men who experience illness. The reasons and processes behind this issue, however, have received limited attention. Conclusions., Principally, the role of masculine beliefs and the similarities and differences between men of differing background requires further attention, particularly given the health inequalities that exist between men of differing socio-economic status and ethnicity. Further research using heterogeneous samples is required in order to gain a greater understanding of the triggers and barriers associated with the decision making process of help seeking behaviour in men who experience illness.

    Robotic vs. laparoscopic Nissen fundoplication for gastro-oesophageal reflux disease: systematic review and meta-analysis

    THE INTERNATIONAL JOURNAL OF MEDICAL ROBOTICS AND COMPUTER ASSISTED SURGERY, Issue 2 2010
    S. R. Markar
    Abstract The aim of this meta-analysis was to compare clinical outcome following laparoscopic and robotic Nissen fundoplication. A systematic literature search of Medline, Embase and Cochrane Library databases was performed. Primary outcome measures were the requirement for re-operation, postoperative mortality and postoperative dysphagia. Secondary outcome measures were operative time, length of hospital stay, operative complications and cost. Six randomized trials, of 226 patients, were included in this meta-analysis. There was no significant difference in requirement for re-operation or in postoperative dysphagia. There was a significantly reduced total operative time in the laparoscopic group (weighted mean difference = 4.154; 95% CI = 1.932,6.375; p = 0.0002). There was no significant difference between robotic and laparoscopic groups for hospital stay or operative complications. Clinical results from robotic Nissen fundoplication were comparable to the standard laparoscopic approach, but there was associated increased operative time and procedure cost.

    Hemangiomas: Evaluation and Treatment

    DERMATOLOGIC SURGERY, Issue 5 2001
    Scott M. Dinehart MD
    Background. Hemangiomas are common skin tumors of infancy that have undergone recent changes in nomenclature, methods of evaluation, and treatment. Objective. To review the nomenclature, epidemiology, evaluation, and treatment of common hemangiomas. Methods. A literature search was conducted utilizing MEDLINE and the Cochrane library databases. Text search words used were "hemangioma" and "infancy." The clinical experience of the authors was also used to formulate the review. Results. There have been many advances in nomenclature and therapeutic options for children with hemangiomas. Hemangiomas are proliferative tumors of infancy that should be distinguished from structural malformations, such as port-wine stains and lymphangiomas. Conclusion. Natural involution remains a viable treatment option for the majority of patients with uncomplicated hemangiomas. Excisional surgery, laser, and pharmacologic remedies are indicated for a subset of complicated hemangioma patients. [source]

    How to run an effective journal club: a systematic review

    JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 5 2008
    Y. Deenadayalan BPT IMMP BEHM (MBA)
    Abstract Background, Health-based journal clubs have been in place for over 100 years. Participants meet regularly to critique research articles, to improve their understanding of research design, statistics and critical appraisal. However, there is no standard process of conducting an effective journal club. We conducted a systematic literature review to identify core processes of a successful health journal club. Method, We searched a range of library databases using established keywords. All research designs were initially considered to establish the body of evidence. Experimental or comparative papers were then critically appraised for methodological quality and information was extracted on effective journal club processes. Results, We identified 101 articles, of which 21 comprised the body of evidence. Of these, 12 described journal club effectiveness. Methodological quality was moderate. The papers described many processes of effective journal clubs. Over 80% papers reported that journal club intervention was effective in improving knowledge and critical appraisal skills. Few papers reported on the psychometric properties of their outcome instruments. No paper reported on the translation of evidence from journal club into clinical practice. Conclusion, Characteristics of successful journal clubs included regular and anticipated meetings, mandatory attendance, clear long- and short-term purpose, appropriate meeting timing and incentives, a trained journal club leader to choose papers and lead discussion, circulating papers prior to the meeting, using the internet for wider dissemination and data storage, using established critical appraisal processes and summarizing journal club findings.

    Antibiotics for Reduction of Posttonsillectomy Morbidity: A Meta-Analysis,

    THE LARYNGOSCOPE, Issue 6 2005
    Collin M. Burkart BS
    Abstract Objective: To reconcile conflicting published reports regarding the clinical efficacy of postoperative antibiotics for reduction of posttonsillectomy morbidity. Study Design: Systematic review (meta-analysis). Methods: Meta-analysis of seven randomized controlled trials of postoperative oral antibiotics in patients undergoing tonsillectomy or adenotonsillectomy. Postoperative pain and time to return to normal activity and diet were studied as distinct end points using a random effects model with weighted mean difference (RevMan 4.2). Search strategy included electronic searches of PubMed and Cochrane library databases; cross-referencing textbooks, reviews, and original trials; and contacting experts in the field. Results: Subjects treated with antibiotics experienced an earlier return to a normal diet (,1.22 days; 95% confidence interval [CI] = ,1.97, ,0.48; P = .001) and an earlier return to normal activity (,0.99 days; 95% CI = ,1.80, ,0.17; P = .02). Evaluation of mean pain visual analogue scores (VAS 0,10) over the first 5 and 7 postoperative days failed to demonstrate any significant effect of antibiotic therapy (VAS difference over 5 days = 0.41; ,1.18, 2.00; P = .61) (VAS difference over 7 days = ,0.64; ,3.46, 2.18; P = .66). Cost analysis suggests routine therapy may be cost-effective but did not include analysis of side effects or resistance resulting from antibiotic usage. Conclusion: The results of this systematic meta-analysis suggest that postoperative oral antibiotics do not significantly reduce posttonsillectomy pain but result in an earlier return to normal activity and diet by approximately 1 day. Given the frequency that tonsillectomy is performed, this possible benefit should be weighed against the cost and potential side effects of routine antibiotic therapy. [source]
