The blood supply of the lower spinal cord is heavily dependent on the artery of Adamkiewicz. The goal of this study was to elucidate the effects of lumbar subarachnoid hemorrhage (SAH) on the lumbar 4 dorsal root ganglion (L4DRG) cells secondary to Adamkiewicz artery (AKA) vasospasm. ⋯ Decreased volume of the lumen of the artery of Adamkiewicz was observed in animals with SAH compared with controls. Increased degeneration the L4 dorsal root ganglion in animals with SAH was also noted. Our findings will aid in the planning of future experimental studies and determining the clinical relevance on such studies.

Schwannomais, usually, benign tumor of nerve sheath that occurs evenly along the spinal cord. Intra-pelvic schwannoma is very rare entity that may arise from lumbosacral nerve roots or from sciatic nerve. Radicular pain of the lower limb as a presenting symptom of pelvic schwannoma is extremely rare. ⋯ Uniquely, we found the tumor to be arisen from lumbosacral trunk not from a root or peripheral nerve. Most cases with intra-pelvic schwannoma present so late with vague abdominal and pelvic discomfort or pain, low back pain, urinary and bowel symptoms because of compressive effect of the tumor, or incidentally following gynecologic work-ups; So, these patients are mostly referred to gynecologists and urologists. A neurosurgeon should have a high degree of suspicion to diagnose such an entity among his or her patients presented with pains typical for discopathy.

High spinal cord injury (HSCI) is one of the devastating traumatic injuries. 80% of these patients are young male, and 93% will have major neurological disabilities. There is a paucity of literature about prolonged bradycardia in HSCI patients. The aim of this study was to know the prevalence, risk factors, precipitating factors for prolonged bradycardia in the HSCI patients. ⋯ Prolonged bradycardia was associated with significantly higher incidence of asystole. Endotracheal suctioning and positioning of HSCI patients were significant provocative factors for prolonged bradycardia; hypotension on admission, pneumonia and tracheostomy were the risk factors for the development of prolonged bradycardia in these patients.

Baastrup's disease is an uncommon entity in the elderly spine and it is very rare in the pediatric age group. There are only few case reports in the literature containing Baastrup's disease in pediatric spine. ⋯ Backache is one of the most common causes of morbidity in these patients and but sometimes patient can be asymptomatic with or without swelling on the back. Here, we present a case of 10-year-old female child with silent swelling on low back region diagnose as Baastrup's disease.

Nonmissile orbitocranial penetrating brain injuries are uncommonly dealt with in a civilian context. Surgical management is controversial, due to the lack of widely accepted guidelines. A 52-year-old man was hit in his left eye by a metallic foreign body (FB). ⋯ He had suspended antiepilectic therapy at that time. A case-by-case tailored approach is mandatory to achieve the best outcome in such a heterogeneous nosological entity. Case reporting is crucial to further understand its mechanism and dynamics.
