Evaluation of Microwave Synthesis of Ceramic Pigments Based on In Situ Dielectric Characterization.

The application of microwave technology for efficient and environmentally friendly synthesis of ceramic pigments is a successful and rapidly evolving area of research. However, a clear understanding of the reactions and their relationship with the material absorbance has not been fully achieved. The present study introduces an in situ permittivity characterization technique, which serves as an innovative and precise tool for assessing the microwave synthesis of ceramic pigments.

Silk flow-diverter stent for the treatment of complex intracranial aneurysms: A one-year follow-up multicenter study.

Background Flow-diverter stents have been successfully used in the treatment of complex aneurysms with limited therapeutic alternatives. We report our experience using the Silk flow diverter (SFD; Balt Extrusion, Montmorency, France) for the treatment of complex aneurysms in four Argentine centers. Methods We conducted a retrospective review of 246 consecutive patients who were treated with the SFD at four Argentine centers between January 2009 and January 2017.

Pseudotumoral chagasic meningoencephalitis as the first manifestation of acquired immunodeficiency syndrome.

Background: Patients with AIDS frequently show secondary involvement of the brain by different infectious agents, and Chagas' disease is now recognized as a potential opportunistic infection. To our knowledge, pseudotumoral chagasic meningoencephalitis has not been previously reported as the first manifestation of AIDS.

Methods And Results: A 30-year-old Argentinian man without any risk factor for HIV infection was admitted to the hospital with an acute onset of drowsiness.

Postpartum bilateral subdural hematomas following spinal anesthesia: case report.

Background: Intracranial subdural hematoma is an exceptionally rare complication of spinal anesthesia. We report a case of this infrequent event and consider the influence of cerebral atrophy as a predisposing factor.

Methods And Results: This 18-year-old woman with severe headaches was admitted to the hospital 42 days after delivery.

Special report on reimbursement. HCFA enacts new enforcement remedies covering nursing facilities.

While the regulations are revolutionary in their use of "substantial compliance," the interpretation and application of HCFA's new remedial scheme are still uncertain, as states are given broad discretion in defining important terms and in applying and interpreting the criteria to select remedies. Further complicating the issue is the fact that some states, including California, intend to seek waivers from HCFA to substitute their own state enforcement systems for most, if not all, of the new federal system. Based upon these uncertainties, the enforcement of nursing facility standards will likely be in a state of flux for some time to come.
