L-arginine supplementation significantly increased plasma nitrates and nitrites and endothelial nitric oxide synthase mRNA levels and improved ultrastructural changes in aortic endothelium and endothelium-dependent vasodilator response.
L-arginine prevents aortic ultrastructural changes and reverses VED induced by high-fat diet in rats exposed to hypoxia, which may have implications for VED induced by high-fat diet in high altitude dwellers.

Here we describe three cases and analyzed the 109 cases of lumbar dermal cysts described in the literature in the last 20 years. We report a pediatric patient with a dermoid cyst posterior to a lumbar surgery for myelomeningocele repair with bad evolution; and two adult patients with the affection of the motor and autonomic function with good surgical outcomes. In approximately half of the reviewed cases, it was reported at least one complication. In fact, two cases had a fatal outcome. We discuss relevant characteristics of these lesions and those aspects probably associated with complications and bad outcomes.
Bronchial asthma (BA) is a chronic disease of the airways. The great majority of BA exacerbations are associated with respiratory viral infections. Recent findings point out a possible role of proinflammatory cytokine interleukin-33 (IL-33) in the development of atopic diseases. Although, little is known about the role of IL-33 in virus-induced BA exacerbations.
We used mouse models of RSV (respiratory syncytial virus)-induced inflammation exacerbation in OVA-sensitized mice and RSV infection alone in adult animals to characterize expression of il33 in the mouse lungs. Moreover, we studied the influence of il33 knockdown with intranasally administrated siRNA on the development of RSV-induced inflammation exacerbation. In addition, we evaluated the expression of IL33 in the ex vivo stimulated PBMCs from allergic asthma patients and healthy subjects with and without confirmed acute respiratory viral infection.
Using mouse models, we found that infection with RSV drives enhanced il33 mRNA expression in the mouse lung. Treatment with anti-il33 siRNA diminishes airway inflammation in the lungs (we found a decrease in the number of inflammatory cells in the lungs and in the severity of histopathological alterations) of mice with RSV-induced inflammation exacerbation, but do not influence viral load. Elevated level of the IL33 mRNA was detected in ex vivo stimulated blood lymphocytes of allergic asthmatics infected with respiratory viruses. RSV and rhinovirus were the most detected viruses in volunteers with symptoms of respiratory infection.
The present study provides additional evidence of the crucial role of the IL-33 in pathogenesis of RSV infection and virus-induced allergic bronchial asthma exacerbations.

Opioid prescriptions have been implicated as one of the proximate causes of the national opioid epidemic. Children and adolescents and their families are at risk for increased opioid exposure through prescriptions after surgery. In pediatric urologic surgery, indications for postoperative opioids can vary widely and a focus on opioid stewardship is important to reduce potential harms.
To measure the efficacy of a quality improvement initiative aimed to reduce post-operative opioids for pain management in a large pediatric surgical cohort.
Patients undergoing ambulatory pediatric urologic surgery at a tertiary children's hospital between July 2016 to June 2019 were analyzed. Structured physician peer-to-peer comparisons, electronic health record redesign and a standardized pain management protocol were implemented. Rate of opioid prescriptions per month, utilization of non-opioid analgesia, unplanned encounters in the emergency department and/or office during implementation were aggregated. Opioid doses d postoperative recovery time of a median 2 (IQR 1-4) days to full resumption of pre-operative level of activity. High satisfaction with opioid reduction in post-operative pain management was reported (median score of 10 (IQR 8-10)).
Opioid prescriptions and utilization may be minimized without increasing unplanned encounters or adversely affecting quality of life. The QI framework utilized in this process can be implemented to reduce opioid exposure in other surgical patient populations.

To determine optimal timing of biopsy for suspected discitis-osteomyelitis (DOM) with respect to preliminary blood culture results and the effect of biopsy timing on hospital length of stay (LOS).
This retrospective study reviewed disc/vertebral biopsies for suspected DOM performed between 2010 and 2018. A total of 107 disc/vertebral biopsies were performed on 96 inpatients (mean ± SD age 57.9 ± 14.5 years, 68 men/28 women) for suspected DOM, and 100 cases of DOM were clinically confirmed and treated. Descriptive and regression statistics were performed with LOS as the primary outcome.
Of disc biopsies in clinically confirmed cases, 68% were positive; 20% of all biopsies had preliminary positive blood cultures after 2 hospital days. There was no difference in LOS between cases with biopsy performed ≤ 2 days after blood culture and cases with biopsy performed > 2 days after blood culture (P= .40). Regression analysis showed no association between positive biopsy results and sepsis, white blood cell (WBC) count, erythrocyte sedimentation rate (ESR), or C-reactive protein (CRP). Biopsy yield was not significantly decreased in patients previously taking antibiotics (P= .09).
Waiting 2 days for preliminary blood culture results could avoid disc/vertebral biopsy in 20% of patients and does not significantly impact hospital LOS. Additionally, clinical factors (sepsis, WBC count, CRP, and ESR) do not have predictive value for positive disc biopsy results.
