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.

Successful treatment of chronic anal fissure utilizing sacral nerve stimulation.

Objective: This is a report of a novel treatment approach for chronic anal fissure using minimally invasive sacral nerve stimulation (SNS).

Measurements: The patient underwent uneventful placement of 1 temporary 8-electrode lead (Medtronic Inc, Minneapolis, Minnesota) for sacral nerve root stimulation.

Results: The patient experienced instantaneous relief of perineal pain after start of SNS and steady healing of the fissure by the end of the second week.

Treatment of intractable hip pain after THA and GTB using peripheral nerve field stimulation: a case series.

Objective: It has been estimated that 10%-35% of patients who undergo total hip arthroplasty (THA) have chronic postoperative pain, most often located at the greater trochanter. After greater trochanteric bursectomy (GTB), patients also may continue to experience chronic surgical site pain. Chronic pain has a neuropathic component, which often responds poorly to opioids.

Treatment of cancer-related chest wall pain using spinal cord stimulation.

Objective: it has been estimated that 15% to 40% of chronic cancer pain has a neuropathic component, and this type of pain often responds poorly to opioids. In an attempt to provide increased pain relief for patients with intractable cancer pain, unconventional agents and interventional management approaches have received considerable attention. Spinal cord stimulation (SCS) has been used with increased frequency for the treatment of intractable cancer pain.

[Three new species of brevibacteria--Brevibacterium antiquum sp. nov., Brevibacterium aurantiacum sp. nov. and Brevibacterium permense sp. nov].

This work deals with the taxonomic study of 12 orange-pigmented bacteria isolated from permafrost sediments, rice plots, and soils contaminated with wastes from the chemical and salt industries, which were assigned to the genus Brevibacterium on the basis of phenotypic characteristics, as well as of some strains described previously as Brevibacterium linens. The study revealed three genomic species, whose members and the type strains of the closest species of Brevibacterium had DNA similarity levels between 24 and 59%. The strains of the genomic species differed from each other and from the known species of Brevibacterium in some physiological and biochemical characteristics, as well as in the sugar and polyol composition of their teichoic acids.

[Micromycetes and actinobacteria under conditions of many years of natural cryopreservation].

Almost all of the investigated samples of the Arctic and Antarctic permafrost sediments of different genesis with ages from 5-10 thousand to 2-3 million years were found to contain viable micromycete and bacterial cells. The maximum amounts of viable cells of fungi (up to 10(4) CFU/g air-dried sample) and bacteria (up to 10(7)-10(9) CFU/g air-dried sample) were present in fine peaty sediment samples taken from different depths. The identified micromycetes belonged to more than 20 genera of the divisions Basidiomycota, Ascomycota, and Zygomycota, and some represented mitosporic fungi.

[Disorders of erythrocyte deformability in patients with acute suppurative-septic diseases of the lung and pleura].

In 163 patients with acute suppurations of lungs and pleura a substantial reduction of deformability of erythrocytes was established. The maximum increased rigidity of blood red cells was noted at the peak of the pyo-destructive process and postoperative period as well as in the complicated course of the postoperative period. The curative plasmapheresis, general hyperbaric oxygenation exert positive influence upon plastic properties of erythrocytes.
