Contrast-enhanced ultrasound (CEUS) versus computed tomography angiography (CTA) in detection of endoleaks in post-EVAR patients. Are delayed type II endoleaks being missed? A systematic review and meta-analysis

Purpose

The purpose of this systematic review is to assess the accuracy of contrast-enhanced ultrasound (CEUS) to computed tomography angiography (CTA) for the detection of endoleaks within EVAR surveillance program.

Material and methods

A systematic review in Pubmed, Embase and Cochrane database was performed. Articles assessing diagnostic accuracy and comparative modality (CTA vs. CEUS) for endoleaks in adult patients within surveillance programs were retrieved. Methodological assessment was performed, using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tools. The sensitivity and specificity of data were extracted and statistical analysis was performed using MetaDiSc version 1.4.

Results

Eight articles were found eligible (n = 454 patients). The pooled sensitivity of CEUS at detecting endoleak is 0.914 (CI 0.866–0.949) and pooled specificity is 0.782 (CI 0.741–0.820).

Conclusion

The CEUS with its dynamic nature and longer scanning window demonstrated to be a highly sensitive modality for endoleak detection in comparison to CTA in delayed endoleaks type II.

Family-based intervention to enhance infant-parent relationships in the neonatal intensive care unit

OBJECTIVE: To examine how family-based interventions in the neonatal intensive care unit (NICU) may change parental knowledge and behaviors and decrease stress. METHODS: Eighty-four high-risk mother-infant dyads were randomly assigned to two intervention and one control groups. Group 1 (n = 28) participated in a demonstration of infant reflexes, attention, motor skills, and sleep-wake states. Group 2 (n = 31) viewed educational materials. Group 3 (n = 25), controls, participated in an informal discussion. Parent-infant interactions (Nursing Child Assessment Feeding Scale) were videotaped. Mothers completed measures of stress (Parenting Stress Index) and knowledge of infant cues (Knowledge of Preterm Infant Behavior Scale). RESULTS: Mothers in both intervention groups evidenced greater knowledge and more contingent and sensitive interactions with their infants than did the control group. Stress also differed across groups, and all mothers reported scores above norms. CONCLUSIONS: In a high-risk sample, short-term, family-based NICU interventions may enhance mothers' knowledge, sensitivity, contingency, and stress.     

A case of relapsing flitting bilateral idiopathic orbital inflammation

Idiopathic orbital inflammation (IOI) is defined as a benign non-infective clinical syndrome characterized by features of non-specific inflammation of the orbit without identifiable local or systemic causes. This can be called orbital myositis if the inflammation is predominantly in the orbital muscles. It is a diagnosis of exclusion based on clinical, radiological, and if necessary, histological findings. The most commons symptoms are swelling, ptosis, proptosis and painful eye movements. To our knowledge, this patient is the first with IOI to demonstrate relapsing flitting bilateral involvement of several individual extra-ocular muscles.     

A pilot study of the SNOT 22 score in adults with no sinonasal disease

Objective: To determine the SNOT 22 score in a normal population. Study design: Analysis of SNOT 22 scores participants with no sinonasal disease. Setting: Bath, UK. Participants: 116 participants from a local hospital and tennis club. Results: Results were obtained from 54 men and 62 women with a mean age of 40 (range 19–75). SNOT score ranged from 0–50 with a mean score of 9.3 (95% confidence interval range of 7.5–11.1). The modal score was 0 and the median score 7 (95% confidence interval range of 5–8). Conclusion: Due to the scewed nature of the data, the median score (7) is taken as the normal SNOT 22 score. We recommend that in an clincial situation a SNOT 22 score of 7 be used a a guide for “normal”, and that care should be taken when suggesting treatment on patients with a score below this level.     

Early aggressive intra-venous pulse cyclophosphamide therapy for interstitial lung disease in a patient with systemic sclerosis. A case report

Interstitial lung disease is an important cause of mortality and morbidity in patients with systemic sclerosis (SSc). There are currently no recommended guidelines for management of these patients. This is probably due to the rarity of this condition, as well as clinical trials with only a small number of cases. There are published case report and case series along with the two main trials, viz. Scleroderma Lung Study and the Fibrosing Alveolitis Study, but again, there is no consensus on treatment protocols. In this report, we present a case of aggressive interstitial lung disease in a patient with SSc, which improved dramatically on treatment with intra-venous cyclophosphamide and high dose prednisolone therapy.     

Conceptual issues specifically related to health-related quality of life in critically ill patients

During recent years increasing attention has been given to the quality of survival in critical care. Health-related quality of life (HRQOL) is an important issue both for patients and their families. Furthermore, admission to the intensive care unit can have adverse psychological effects in critically ill patients. Recent studies conducted in critically ill patients have measured HRQOL. However, usually absent from such reports are evaluations of conceptual issues, addressing factors such as why HRQOL should be measured in critically ill patients, how to define and standardize domains of HRQOL, whether proxies can provide useful information about HRQOL in critically ill patients, whether response shift occurs in critically ill patients, and whether post-traumatic stress disorder (PTSD) occurs in critically ill patients. Some studies reported moderate agreement between patients and their proxies, although lower levels of agreement may be reported for psychosocial or physical functioning. Response shift (adaptation and change in perception) appears to be an important phenomenon and likely to be present, but it is seldom measured when estimating HRQOL in critically ill patients. Furthermore, vigilance for symptoms of PTSD and early interventions to prevent PTSD are needed.     

Pathway analysis of gene signatures predicting metastasis of node-negative primary breast cancer

Background  

Published prognostic gene signatures in breast cancer have few genes in common. Here we provide a rationale for this observation by studying the prognostic power and the underlying biological pathways of different gene signatures.
