Using The Comaneci temporary assist device to expand a partially expanded flow diverting stent.

The article describes a case of successful treatment of cerebral aneurysm with a flow-diverting stent using the temporary assist device Comaneci (Rapid Medical, Yokneam, Israel). Clinical symptoms and methods of instrumental diagnostic for cerebral aneurysm are presented. Endovascular management technique is described in detail.

Ultrafine particles derived from mineral processing: A case study of the Pb-Zn sulfide ore with emphasis on lead-bearing colloids.

Although mining and mineral processing industry is a vast source of heavy metal pollutants, the formation and behavior of micrometer- and nanometer-sized particles and their aqueous colloids entered the environment from the technological media has received insufficient attention to date. Here, the yield and characteristics of ultrafine mineral entities produced by routine grinding of the Pb-Zn sulfide ore (Gorevskoe ore deposit, Russia) were studied using laser diffraction analysis (LDA), dynamic light scattering (DLS) and zeta potential measurement, microscopy, X-ray photoelectron spectroscopy, with most attention given to toxic lead species. It was revealed, in particular, that the fraction of particles less that 1 μm in the ground ore typical reaches 0.

Spinal cord stimulation as alternative treatment for chronic post-herniorrhaphy pain.

Objective: Our goal was to determine the efficacy of spinal cord stimulation for patients with intractable post-herniorrhaphy pain which conventional treatment failed to ameliorate.

Procedure: The patients underwent an uneventful spinal cord stimulator (SCS) trial with percutaneous placement of two eight-electrode epidural leads (Medtronic Inc, Minneapolis, MN, USA) to level T7-T8-T9.

Results: Upon experiencing excellent pain relief over the next two days during the trial, the patients were implanted with permanent leads and rechargeable or non-rechargeable generators two to four weeks later and reported sustained pain relief during following 12 months after implantation.

Treatment of chronic chest wall pain in a patient with Loeys-Dietz syndrome using spinal cord stimulation.

Objective: Spinal cord stimulation (SCS) has been used with increased frequency for the treatment of intractable pain including chronic chest pain.

Methods: The patient with a history of Loeys-Dietz syndrome who underwent repair of pectus excavatum with subsequent chronic chest wall pain underwent an uneventful SCS trial with percutaneous epidural placement of two temporary eight-electrode leads placed at the level of T3-T4-T5.

Results: After experiencing excellent pain relief over the next two days, the patient was implanted with permanent leads and rechargeable generator four weeks later and reported sustained pain relief at 12-month follow-up visit.

Sacral nerve stimulation: a novel treatment of chronic anal fissure.

Objective: The purpose of this pilot study of 5 patients was to test the feasibility of a new treatment approach for chronic anal fissure utilizing minimally invasive sacral nerve stimulation before designing and conducting a larger prospective controlled study.

Measurements: The patients underwent uneventful placement of one temporary 8-electrode Octad lead for sacral nerve root stimulation. Stimulation was conducted for 20 minutes 3 times per day.
