The draining of a dam is a relatively rare event, however, it can have severe consequences for a watercourse connected to that reservoir. In order to understand the effects of the draining on the mobility of pollutants stored in the bottom sediments, the concentrations of heavy metals and arsenic were measured in pore water, river water, and sediments sampled from three emptied reservoirs in Germany. Two of these sites were analyzed immediately after the draining, while the third reservoir was studied one and a half years after the complete discharge of the stored water. Heavy metal and arsenic concentrations within the sediments varied among the studied dams as a result of different geological characteristics and the degree of anthropogenic impacts. Based on the analysis of pore water samples, the concentrations of heavy metals and arsenic were not significantly altered shortly after the draining. However, increased concentrations of As, Fe, Cd, Ni, and Zn were measured in pore water samples after a longer duration of sediment exposure, which altered the redox conditions and sediment properties. The changes in Cu, Cr, Mn, and Pb concentrations in pore water samples were less pronounced. As a result of the pore water drainage increased dissolved heavy metal concentrations were found in the discharge water immediately after draining. At the third site, which had been emptied for one and a half years, only for Mn, a concentration increase was detected in the reservoir discharge water, which emphasizes the strong temporal dynamic of the mobilization of the analyzed elements.

The Rule of Nines, also known as the Wallace Rule of Nines, is a tool used by trauma providers to assess the total body surface area (TBSA) involved in burn patients. Measurement of the initial burn surface area is important in estimating fluid resuscitation requirements since patients with severe burns will have massive fluid losses due to the removal of the skin barrier. This tool is only utilized for second-degree and third-degree burns and aids the provider in quick assessment to determine the severity and intravenous fluid needs. Alterations to the Rule of Nines may be made based on body mass index (BMI) and age. The Rule of Nines has been shown to be the most frequently recited algorithm by physicians and nurses in numerous studies.
- ACOs with risk-bearing experience are likely taking steps to reduce low-value medical services. [Journal Article]
- AJAm J Manag Care 2018 Jul 01; 24(7):e216-e221
- CONCLUSIONS: In the first year of implementation, just one-third of ACOs had taken steps to reduce the use of low-value medical services. Safety-net ACOs and those with little experience as a risk-bearing organization need more time and support from healthcare payers and the Choosing Wisely campaign to prioritize the reduction of overuse.

Surgery for intraventricular tumors remains a controversial and evolving field, with endoscopic resection becoming more popular. We present a series of nine consecutive cases of purely endoscopic resection of intraventricular tumors with the aid of an ultrasonic aspirator specific for neuroendoscopy. Nine patients (five men, four women) aged 18-74 years (mean 43.7) underwent surgery. The most common symptom was headache. In all cases, magnetic resonance imaging showed single supratentorial intraventricular lesions (five lateral ventricle, four third ventricle). The average maximum diameter was 20.5 mm (range 11-42). Associated hydrocephalus was found in eight cases at diagnosis. Five patients underwent complete macroscopic resection. Three underwent subtotal resection and one underwent partial resection (two thirds of the tumor). The mean endoscopic procedure time was 70 min (37-209). The eight patients with associated hydrocephalus also underwent endoscopic septostomy to improve cerebral spinal fluid circulation, with one patient additionally requiring endoscopic third ventriculostomy and another requiring Monro foraminoplasty. One patient required ventriculoperitoneal shunting. The mean post-operative follow-up was 15.1 months (range 2-33). At the time of analysis, no patient showed recurrence or regrowth of the operated lesion. The histological diagnoses and degree of resection were three subependymomas with complete resection, three colloid cysts with two complete and one subtotal resection, one pilocytic astrocytoma with partial resection (approximately two thirds of the lesion), one epidermoid tumor with subtotal resection, and one central neurocytoma with subtotal resection. The endoscopic ultrasonic surgical aspirator can be a safe and effective tool for the removal of intraventricular tumors, even in firmer solid lesions.

Skin grafting is the routine standard of care to manage third degree burns and problematic skin defects. Several commercially available dermal substitutes and biologic skin equivalents are placed in the wound bed to facilitate the healing process of the skin grafts, as well as to provide mechanical support for the cells to grow and to delay the contracture. To study pathology and develop new therapies, an immune-competent rat model is required. We have created two different skin graft animal models to mimic the clinical skin grafting operation, the dorsum skin grafting (DG) and inguinal skin grafting (IG). To create a recipient site, a full-thickness, round excision wound was created on the dorsum between rats' scapular angles, covered with DG or IG. Graft contraction was quantified and tissue was harvested on predetermined time points for analysis. Histologic staining was performed to differentiate between DG and IG. Collagen deposition was assessed with Masson's trichrome staining. Mast cells were detected with Toluidine blue. Macrophages were stained with CD68 immune. Vascularity was assessed with functional vessels numbers. Cell proliferation was assessed with Ki67 immune. This model has all the advantages of murine models, such as an abundance of genetic variants and applicable tools, low cost, and practical housing techniques, all of which will promote the development of new therapies and testing new biologic skin equivalents and dermal substitutes.
