Article Synopsis
- The study aims to assess how effective tranexamic acid is in decreasing blood loss and surgical time in nasal surgeries.
- It included 16 randomized clinical trials with a total of 1,108 patients and found that tranexamic acid significantly reduced both intraoperative blood loss and the duration of surgery.
- The findings indicate that tranexamic acid plays a critical role in these procedures, though the research is somewhat limited by the small number of available studies.
Measuring pituitary tumor volume: a comparison of the simplified and non-simplified ellipsoid equation with the 3D planimetric volume assessment.
Pituitary
August 2023
Purpose: The ellipsoid equation came in an attempt to facilitate the estimation of tumor volume, by measuring the height, width, and anteroposterior length of the lesion. The estimated tumor volume can sometimes be different between methods, thus, it is of extreme interest to evaluate if the methods are significantly different, as well as to discuss the main limitations of each one.
Methods: This is an observational, analytical, cross-sectional study.

Factors related to occupational accidents among nursing professionals from a public hospital in northern Brazil between the years 2009 to 2016.
Rev Bras Med Trab
December 2019
Background: Occupational accidents are considered public health problems, where there are gaps regarding studies on this theme in the northern region of Brazil with focus on nursing professionals.
Aims: To analyze the factors related to occupational accidents in nursing professionals occurred in a large public hospital in Belém (PA) from January 2009 to December 2016.
Method: Analytical, retrospective and longitudinal study with a quantitative approach by means of documentary census with a sample of 211 Work Accident Registry.
Objective: The proximity of the spinal cord to compressive metastatic lesions limits radiosurgical dosing. Open surgery is used to create safe margins around the spinal cord prior to spinal stereotactic radiosurgery (SSRS) but carries the risk of potential surgical morbidity and interruption of systemic oncological treatment. Spinal laser interstitial thermotherapy (SLITT) in conjunction with SSRS provides local control with less morbidity and a shorter interval to resume systemic treatment.

- Schizencephaly is a rare brain malformation linked to severe neurological issues, with limited research available on its effects and patient characteristics.
- A literature review identified 156 studies involving 734 patients, revealing common issues such as microcephaly, seizures, and bilateral clefts, with significant correlations found between these factors and neurocognitive impairments.
- Key findings suggest that bilateral clefts, motor impairments, microcephaly, and corpus callosum agenesis are major predictors of cognitive dysfunctions in schizencephaly patients, but the lack of large patient groups hampers broader comparisons.
Article Synopsis
- * A study evaluated 597 CT scans to analyze ACP's anatomy, revealing that nearly 39% showed variations, with specific findings on ACP size and pneumatization patterns.
- * Understanding these variations and utilizing preoperative CT scans could significantly enhance the safety and effectiveness of surgeries involving the ACP.
Intrasphenoid septations inserted into the internal carotid arteries: a frequent and risky relationship in transsphenoidal surgeries.
Braz J Otorhinolaryngol
May 2017
Article Synopsis
- Intrasphenoid septations need to be completely removed during expanded endonasal transsphenoidal surgery, especially if they are near the internal carotid artery (ICA) to avoid vascular injuries.
- The study aims to assess how common these septations are in relation to the internal carotid artery protuberance (ICAp).
- Analysis of CT scans from 421 patients revealed that over half had septations in the ICAp, with higher rates observed in patients with well-pneumatised sphenoid sinuses, highlighting the need for detailed pre-operative evaluations.
