Spinal cord infarction is a rare condition, accounting for only a small percentage of strokes. It can be classified into cervical and thoracolumbar infarctions, with various factors contributing to its occurrence. Sildenafil, a phosphodiesterase type 5 inhibitor commonly used for erectile dysfunction, has been associated with cardiovascular side effects, including transient hypotension. In this case report, we present the unusual occurrence of spinal cord infarction in a 65-year-old man who had self-administered high doses of sildenafil without a doctor's prescription. The patient experienced severe radicular pain in the lumbar region and subsequent weakness in the lower limbs. Evaluation revealed an anterior spinal cord infarction in the thoracic region, confirmed by MRI imaging. After excluding other potential causes, it was concluded that the intake of sildenafil likely led to systemic hypotension, resulting in spinal cord infarction. This case highlights the importance of considering sildenafil as a possible contributor to spinal cord infarction, particularly when used at high doses. Further studies are needed to better understand the relationship between sildenafil and vascular complications, including spinal cord infarction.

Background: Spinal cord injury/disease (SCI/D) profoundly affects both sexuality and urinary function. Catheterization is often necessary to manage bladder voiding and it can interfere with sexual activity.
Aim: We aim to investigate the effect of the bladder evacuation method on sexual activity in women with chronic SCI/D.

Despite advancements in preclinical and clinical spinal cord stimulation (SCS) research, the mechanisms of SCS action remain unclear. This may result from challenges in translatability of findings between species. Our systematic review (PROSPERO: CRD42023457443) aimed to comprehensively characterize the important translational components of preclinical SCS models, including stimulating elements and stimulation specifications.

Background: Currently, there remains a high percentage of complications after lumbar discectomy, while there is no uniform tactic to prevent their development. Purpose of the study was to compare the clinical efficacy and return to work rate (RWR) after total disk replacement (TDR) and microsurgical lumbar discectomy (MLD) in railway workers with lumbar disk herniation (LDH).
Methods: We randomly assigned 75 patients out of a total of 81 patients, between 25 and 35 years of age who had one level LDH to undergo single-level TDR surgery (group I, n=37) or MLD surgery (group II, n=38) in the L4-L5 or L5-S1 segments.

Stem cell transplantation is a promising strategy to establish neural relays in situ for spinal cord injury (SCI) repair. Recent research has reported short-term survival of exogenous cells, irrespective of immunosuppressive drugs (ISD), results in similar function recovery, though the mechanisms remain unclear. This study aims to validate this short-term repair effect and the potential mechanisms in large animals.
