AI Article Synopsis
- The study aimed to investigate how often spinal cord stimulator leads migrate after implantation using current surgical techniques and hardware.
- Researchers reviewed patient records from 2008 to 2011, focusing on those who had percutaneous leads and needed surgical revisions for lead migration.
- Results showed that only 2.1% of patients experienced clinically significant lead migration requiring revision, which is much lower than earlier estimates of 13%-22%, although the study did not identify the reasons for this lower rate.
Article Abstract
Objective: To examine the incidence of percutaneous spinal cord stimulator lead migration, given current hardware and surgical technique.
Materials And Methods: We retrospectively reviewed records of patients who underwent spinal cord stimulator implantation with percutaneous leads at our institution from 2008 through 2011. We determined the number of patients who required surgical revision for clinically significant lead migration.
Results: Clinically significant lead migration requiring surgical revision occurred in three of 143 patients (2.1%) with primary SCS system implants utilizing percutaneous-type leads.
Conclusions: The rate of lead migration observed in our practice was considerably lower than previously published estimates of clinically significant lead migration or revision for lead migration (13%-22%). However, our study did not determine the reason for the decreased rate, which may be influenced by current hardware and implant techniques.

Leukemia covers a broad category of cancer malignancies that specifically affect bone marrow and blood cells. While different kinds of leukemia have been identified, effective treatments are still lacking for most forms, and even those treatments considered effective can lead to relapses. MicroRNAs, or miRNAs, are short endogenous non-coding single-stranded RNAs that help control the epigenetics of gene expression.

Background: Nonsurgical rhinoplasty (NSR) with dermal fillers has gained popularity because of its immediate and visible results, minimal downtime, and long-lasting effects. However, complications such as filler migration can lead to the development of the "Avatar nose," a condition where the nose appears unnaturally wide and bulbous in the nasion area, disrupting facial harmony. This phenomenon is often exacerbated by the presence of a taut nasofrontal ligament, which tethers the periosteum to the dermal layer and influences nasal contour.

Numerous diseases, such as diabetic retinopathy and age-related macular degeneration, can lead to retinal neovascularization, which can seriously impair the visual function and potentially result in blindness. The presence of the blood-retina barrier makes it challenging for ocularly administered drugs to penetrate physiological barriers and reach the ocular posterior segments, including the retina and choroid. Herein, we developed an innovative bifunctional peptide, Tat-C-RP7, which exhibits excellent penetration capabilities and antiangiogenic properties aimed at treating retinal neovascularization diseases.

Dengue virus (DENV) poses a considerable threat to public health on a global scale, since about two-thirds of the world's population is currently at risk of contracting this arbovirus. Being transmitted by mosquitoes, this virus is associated with a range of illnesses and a small percentage of infected individuals might suffer from severe vascular leakage. This leakage leads to hypovolemic shock syndrome, generally known as dengue shock syndrome, organ failure, and bleeding complications.

The resolution phase of neutrophilic inflammation is critical to preventing tissue damage, as observed in diseases characterized by influx of neutrophils such as atherosclerosis and non-healing wounds. Animal models have provided insight into resolution of neutrophilic inflammation via efferocytosis and reverse migration (rM); however, species-specific differences and complexity of innate immune responses make translation to humans challenging.
