Tranexamic acid in bleeding reduction and operative time of nasal surgeries: systematic review and meta-analysis.
Eur Arch Otorhinolaryngol
March 2024
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.
Detection of the source of hemorrhage using postmortem computerized tomographic angiography in a case of a giant juvenile nasopharyngeal angiofibroma after surgical treatment.
Forensic Sci Med Pathol
September 2015
Article Synopsis
- This study discusses the use of postmortem computerized tomographic angiography (PMCTA) in identifying the source of bleeding after surgery in a patient with giant juvenile nasopharyngeal angiofibroma.
- The case showed that PMCTA successfully detected the bleeding source, which conventional autopsy failed to find, indicating PMCTA's effectiveness in forensic investigations.
- The authors highlight the importance of incorporating PMCTA as a routine procedure in forensic medicine to better pinpoint causes of fatal hemorrhage.
The lateral recess of the sphenoid sinus is one of the most common sites of meningocele and spontaneous cerebrospinal fluid (CSF) leak. Despite the availability of several techniques for closure of skull base defects occurring in this location, recurrence still poses a major challenge. This report reviews the experience of surgical repair of lateral sphenoid sinus recess CSF leak at a tertiary referral center and provides a brief discussion of this rare lesion.

- A study in Salvador, Brazil, assessed hemoglobin levels in 1,263 maintenance hemodialysis (MHD) patients, finding that 67.4% had hemoglobin levels below the recommended target of 11 g/dl, highlighting significant anemia issues in this population.
- Most participants were black or mixed race, with high rates of erythropoietin treatment, yet factors like catheter use, recent hospitalizations, and low iron levels were linked to lower hemoglobin.
- The findings suggest that addressing factors such as iron deficiency and malnutrition could improve hemoglobin levels in MHD patients of African descent, furthering understanding of anemia in this demographic.
Objective: To describe the frequency of prescription of phosphate binders (PB) and calcitriol for patients on chronic hemodialysis in Salvador, Brazil, and to assess whether treatment is in agreement with recommendations of the Kidney Disease Outcomes Quality Initiative (K/DOQI).
Methods: Cross section of baseline data of the PROHEMO study. The frequency of prescription of PB and calcitriol according to laboratory indicators of mineral metabolism was compared with K/DOQI recommendations.
