Tumefactive dilated perivascular space with spontaneous regression.

Tumefactive (giant) perivascular spaces of the brain are a rare benign lesion that may occasionally result in localized neurological symptoms and typically do not change in appearance on subsequent imaging studies. Here we report a case of a 65-year-old woman with newly diagnosed lung cancer that underwent routine staging MRI of the brain. She was found to have a cystic temporal lobe lesion with imaging features consistent with a tumefactive perivascular space.

CellKine clinical trial: first report from a phase 1 trial of allogeneic bone marrow-derived mesenchymal stem cells in subjects with painful lumbar facet joint arthropathy.

Background: Lumbar facet joint arthropathy (LFJA) is a major cause of low back pain (LBP), with current treatments offering limited long-term benefits. Bone marrow-derived mesenchymal stem cells (BM-MSCs) show promise due to their immunomodulatory and trophic effects, potentially addressing underlying degenerative processes in LFJA.

Objectives: This initial report describes the outcomes of the first treated patient in an ongoing mutidisciplinary phase 1 clinical trial evaluating the safety and feasibility of intra-articular allogeneic BM-MSCs for painful LFJA.

Environmental variables associated with population structure and Swiss needle cast severity in Western Oregon and Washington.

The environment has a strong influence on the abundance and distribution of plant pathogenic organisms and plays a major role in plant disease. Climatological factors may also alter the dynamics of the interactions between plant pathogens and their hosts. (=) , the causal agent of Swiss needle cast (SNC) of Douglas-fir, is endemic to western North America where it exists as two sympatric, reproductively isolated lineages.

Culture-based identification to examine spatiotemporal patterns of fungal communities colonizing wood in ground contact.

Timber durability is often assessed using small wood stakes exposed in direct soil contact, and the assessment generally emphasizes effects on wood rather than organisms involved. Understanding fungal colonization patterns can help identify key decay agents under varying conditions and use these patterns to improve wood protection strategies. Fungal colonization of red alder (), Douglas-fir () heartwood/sapwood, and western redcedar () field stakes was assessed over 2 y in western Oregon.

Colorectal Cancer Screening in African American HOPE VI Public Housing Residents.

This study explores whether colorectal cancer screening outreach via home visits and follow-up calls is effective among public housing African American residents. It reports on the proportion of returned Fecal Immunochemical Test kits, on the characteristics of study participants, and on their primary reasons for returning the kit. By conducting home visits and follow-up calls, our colorectal cancer-screening outreach resulted in a higher Fecal Immunochemical Test kit return rate than anticipated.

Success of Penile Replantation Using Combination of Cialis, Hyperbaric Oxygen, and SPY Technology.

There are very few studies reporting the techniques utilized in penile replantation. Of those in literature, many agree that the use of microvascular technique results in better outcomes. The most common complications are skin necrosis and venous congestion, which are even higher in replants without arterial supply.

Reconstruction of Traumatic Central Slip Injuries: Technique Using a Slip of Flexor Digitorum Superficialis.

Multiple reconstruction techniques have been described for correction of boutonniere deformities including direct repair, central slip reconstruction, lateral band reconstruction, transverse retinacular ligament reconstruction, staged reconstruction, and extensor tenotomy. Each technique has been reported to have variable results with complications including capsular contracture, loss of proximal interphalangeal flexion, and residual deformity. We describe a surgical technique for central slip reconstruction using a slip of the flexor digitorum superficialis tendon through a bone tunnel.

Intraarticular Distal Radius Fracture Open Reduction Internal Fixation.

Purpose: Intraarticular distal radius fractures are often treated with open reduction and internal fixation (ORIF) through a volar approach. This common approach, however, is technically demanding to restore the articular surface of the radiocarpal joint while respecting soft tissue integrity. The purpose of this video is to demonstrate the surgical technique of volar plate fixation of an intraarticular distal radius fracture.

The influence of patient- and surgeon-specific factors on operative duration and early postoperative outcomes in shoulder arthroplasty.

Background: Increased operative duration has been shown to have demonstrable effects on the outcomes and complications in multiple areas of orthopedic surgery. We sought to determine if patient- and surgeon-specific factors correlated to operative duration in shoulder arthroplasty. Our hypothesis was that increased surgeon and trainee volume would decrease operative times and that more complex pathology would increase operative duration.

Overlooked competing asexual and sexually typified generic names of with recommendations for their use or protection.

With the change to one scientific name for fungal species, numerous papers have been published with recommendations for use or protection of competing generic names in major groups of ascomycetes. Although genera in each group of fungi were carefully considered, some competing generic names were overlooked. This paper makes recommendations for additional competing genera not considered in previous papers.

Safeguards to prevent neurologic complications after epidural steroid injections: consensus opinions from a multidisciplinary working group and national organizations.

Background: Epidural corticosteroid injections are a common treatment for radicular pain caused by intervertebral disc herniations, spinal stenosis, and other disorders. Although rare, catastrophic neurologic injuries, including stroke and spinal cord injury, have occurred with these injections.

Methods: A collaboration was undertaken between the U.

Recommendations on generic names competing for use in Leotiomycetes (Ascomycota).

In advancing to one scientific name for fungi, this paper treats genera competing for use in the phylogenetically defined class Leotiomycetes except for genera of Erysiphales. Two groups traditionally included in the so-called "inoperculate discomycetes" have been excluded from this class and are also not included here, specifically Geoglossomycetes and Orbiliomycetes. A recommendation is made about the generic name to use in cases in which two or more generic names are synonyms or taxonomically congruent along with the rationale for the recommendation.
