BACKGROUND: Research suggests that hypertonic saline (HS) may improve mucous flow in infants with acute bronchiolitis. Data suggest a trend favoring reduced length of hospital stay and improved pulmonary scores with increasing concentration of nebulized solution to 3% and 5% saline as compared with 0.9% saline mixed with epinephrine. To our knowledge, 7% HS has not been previously investigated. METHODS: We conducted a prospective, double-blind, randomized controlled trial in 101 infants presenting with moderate to severe acute bronchiolitis. Subjects received either 7% saline or 0.9% saline, both with epinephrine. Our primary outcome was a change in bronchiolitis severity score (BSS), obtained before and after treatment, and at the time of disposition from the emergency department (ED). Secondary outcomes measured were hospitalization rate, proportion of admitted patients discharged at 23 hours, and ED and inpatient length of stay. RESULTS: At baseline, study groups were similar in demographic and clinical characteristics. The decrease in mean BSS was not statistically significant between groups (2.6 vs 2.4 for HS and control groups, respectively). The difference between the groups in proportion of admitted patients (42% in HS versus 49% in normal saline), ED or inpatient length of stay, and proportion of admitted patients discharged at 23 hours was not statistically significant. CONCLUSIONS: In moderate to severe acute bronchiolitis, inhalation of 7% HS with epinephrine does not appear to confer any clinically significant decrease in BSS when compared with 0.9% saline with epinephrine.

Objectives: To investigate the association between baseline pain drawings and future psychological status, and estimate the prognostic value of pain drawing assessment for predicting somatization, distress, and depression at one-year follow-up, in patients with recurrent or chronic low back pain (RCLBP). Methods: This was a multi-center prospective cohort study of 138 patients with RCLBP. Participating patients completed at baseline and one-year follow-up: a blank pain drawing; the Modified Somatic Perceptions Questionnaire; modified Zung Depression Scale; and Distress and Risk Assessment Method. Pain drawings were analyzed quantitatively using the Pain Sites Score (PSS) and Simple Body Region (SBR) method. The association between baseline pain drawing assessment and one-year psychological status was estimated using correlation and Relative Risk (RR) statistics. Results: We obtained complete data from 81 patients (59%). Psychological status and pain drawings did not differ significantly between completers and non-completers. Pain drawing area at baseline was associated with depression and somatization at one-year follow-up (Spearman's Rho 0.25, P50.022; 0.31 P50.006, respectively). Stronger associations resulted from analyses using the PSS, compared with the SBR. Patients with abnormal PSS pain drawings at baseline had significantly greater RR of depression (RR 6.1, 95% CI 1.1, 33.5), somatization (RR 4.1, 95% CI 1.7, 9.9) and distress (RR 6.8, 95% CI 1.9, 25.3) at one-year follow-up. Discussion: These results provide the first evidence that abnormal baseline pain drawings predict greater risk of abnormal psychological states or poor psychological outcome at one-year follow-up, in patients with RCLBP.

Venous thromboembolism is a condition that includes both deep venous thrombosis and pulmonary embolism. Venous thromboembolism disease can result because of a combination of risk factors, including patient-related, treatment-related, and, more specifically, cancer-related factors. It is not disease-specific or a population-specific disorder, but it is more prevalent in certain specialty populations. This article will cover those specialty populations including cancer, pregnancy, and athletes.

medical cases as being emotionally difficult, which led to the most robust shame reactions. Shame reactions were more common when EMS providers committed selfperceived errors in patient care, whereas guilt reactions were more common when patient outcomes seemed "inevitable" despite any intervention. Common themes related to coping mechanisms included both personal mechanisms which tended to be less successful compared to interpersonal mechanisms, particularly when emotions were shared with colleagues. This reflected a perceived culture change within EMS in which sharing emotions with colleagues was seen as a departure from the "old school" where emotions tended to be kept to oneself. Feelings of inadequacy, low self-worth, and being "not good enough" were frequently identified as lingering emotions after difficult cases that were hard to move on from, corresponding to longstanding shame in these providers. Recovery and resilience varied but tended to be positively associated with a culture in which sharing with colleagues was encouraged, and personal introspection on root causes for the sentinel event.Conclusion: EMS providers often identify complex patient cases as those leading to emotions such as shame and guilt, with shame reactions being more common when a perceived error was committed. Coping mechanisms were varied, but individuals often relied on their co-workers in a sharing environment to adequately process their negative feelings, which was seen as a departure from past practices in EMS personnel. Our hope is that future studies will be able to utilize these findings to identify targets for intervention on negative mental health outcomes in EMS personnel.
