Pedicle morphometry of the C7 and T1 vertebrae in an argentine population.

Background: We evaluated how and whether the pedicular morphometry of the C7 and T1 vertebrae might impact C7/T1 spinal fusions for patients from Argentina.

Methods: Using computed tomography (CT) scans, we evaluated the pedicular morphology at the C7 and T1 levels.

Results: Among 102 male and female CT studies, we observed significant differences in the height, width, length, and morphometry of the C7 and T1 pedicles.

Ventricular Access Utilizing Cutaneous Reference Points: Statistical Analysis and Proposal of a New Ventricular Entry Point.

Objectives: Perform radiologic measurements and analysis of normal brain computed tomography (CT) scans; delineate a new ventricular entry point from cutaneous landmarks, highlighting the potential surgical implications of these findings.

Methods: Six radiologic distances (AR; BR; AL; BL, C, and D) were measured in normal brain CT scans using Horos software. Statistical analysis of the measurements was performed with minitab18 software based on age, sex, and side.

"Ping-pong" fracture: An exclusive entity of neonates and infants? A case analysis and literature review.

Background: "Ping-pong" fractures are a type of depressed fracture in which there is no rupture of the inner or outer table of the skull. It is produced by incomplete bone mineralization. Its appearance is frequent during neonatal and infant ages and is extremely rare outside of these age periods.

Which biological pathways are responsible for the late appearance of brain metastases in renal cell carcinoma? Analysis of eight cases.

Background: Renal cell carcinoma (RCC) represents 1% of all cancers and its brain metastases amount to 8.1% of all metastatic tumors. Late brain metastases are defined as tumors that appear 10 years after diagnosis of the primary lesion.

Distance Between the Corpus Callosum and the Falx Cerebri: A Little Explored Measure with Potential Surgical Implication.

Objective: To perform measurements in normal brain imaging studies from the free edge of the falx cerebri to the genu and the body of the corpus callosum and perform a statistical analysis based on age, type of study, and sex highlighting potential surgical implication of these measurements.

Methods: In 193 normal brain imaging studies, 3 anatomical points of the corpus callosum were used to measure the distance to the falx cerebri. Horos and RadiAnt DICOM Viewer software were used to perform the measurements.

A new, readily accessed and low-cost, device for treating depressed ping pong fractures non-surgically: Technical note.

Objective: The aim of this paper is to describe a low-cost and readily accessed Manual Aspiration Reduction System (MARS) for use treating ping-pong fractures in three patients.

Methods: The MARS is composed of a pediatric anesthesia mask, part of a macro dripper, a 3-way stopcock, and two 60-ml syringes. Prior to its use in our patient, the system was tested on five adult volunteers to maximum negative pressure, and none reported pain during the procedure or experienced any other complication.

A new, low-cost device to treat depressed "ping-pong" fractures non-surgically: technical note.

Objective: The aim of this paper is to describe a low-cost and readily accessed Manual Aspiration Reduction System (MARS) for use treating neonatal ping-pong fractures.

Methods: The MARS is composed of a pediatric anesthesia mask, part of a macro dripper, a 3-way stopcock, and two 60-ml syringes. Prior to its use in our patient, the system was tested on five adult volunteers to maximum negative pressure, and none reported pain during the procedure or experienced any other complication.
