[O-arm Versus C-arm: Comparison of the Learning Curves and Accuracy in Transpedicular Screw Fixation of Lumbar Spondylolisthesis].

Purpose Of The Study: The annual number of spinal fusion procedures has been increasing and is well documented worldwide. The O-arm is slowly becoming the standard for transpedicular screw insertion. The accuracy and safety of this method have been confirmed by many studies.

Primary ventriculitis caused by Streptococcus intermedius - a rare case and challenge with uncertain clinical outcome. Case report.

Aims: To present a case of primary ventriculitis in a 53-year-old patient caused by Streptococcus intermedius, emphasizing the rarity of the condition and the challenges in achieving clinical improvement despite targeted therapy.

Methods: The patient underwent clinical evaluation, including CT and MRI imaging, as well as CSF analysis. Empirical antibiotic therapy was initiated with cefotaxime and metronidazole, followed by targeted therapy based on CSF culture results.

S100B protein as a biomarker and predictor in traumatic brain injury.

Objectives: To determine the prognostic potential of S100B protein in patients with craniocerebral injury, correlation between S100B protein and time, selected internal diseases, body habitus, polytrauma, and season.

Methods: We examined the levels of S100B protein in 124 patients with traumatic brain injury (TBI).

Results: The S100B protein level 72 h after injury and changes over 72 h afterwards are statistically significant for prediction of a good clinical condition 1 month after injury.

[Effects of Tranexamic Acid on Perioperative Blood Loss and Wound Hematoma Development in Lumbar Spine Surgery: a Prospective Randomized Study].

PURPOSE OF THE STUDY Tranexamic acid as a haemostatic agent is commonly used in multiple medical branches. Over the last decade, there has been a steep rise in the number of studies evaluating its effect, i.e.

Unusual foreign body in the nasal cavity after craniofacial injury.

A 68-year-old man with severe craniofacial trauma underwent endoscopic surgery for nasal cerebrospinal fluid leak. During the operation, a plastic object in the shape of a spectacle lens was found wedged in the left nasal passage, which we extracted. As subsequently established from the patient's documentation, it was a dislodged acrylic implant originally placed at the base of the orbit which was surgically treated after an injury to the facial skeleton thirty-five years ago.
