Article Synopsis
- The study aimed to compile and analyze published cases of intrinsic brainstem epidermoid cysts, focusing on their characteristics and treatment methods, especially in pediatric patients.
- Researchers reviewed existing literature and presented a case of a 1.5-year-old boy who underwent successful gross total resection of a cyst discovered incidentally.
- Results showed 21 patients (10 boys, 11 girls) with an average age of 4.85 years, experiencing symptoms like cranial nerve palsy (71.4%) and headache (52.38%), highlighting the need for careful surgical approaches to maximize lesion removal while preserving function.
Article Synopsis
- The study investigates whether opening the ventricular system during surgery for brain tumors in children leads to increased postoperative complications, particularly focusing on cases from 2002 to 2020 involving 43 patients.
- Findings showed that while ventricular opening was linked to a higher rate of subdural hygroma (43% vs. 0%), it did not significantly increase risks for complications like hydrocephalus or infections.
- Overall, the research suggests that ventricular opening during these surgeries is not associated with severe complications and has comparable survival rates to surgeries without ventricular involvement.
Background: The potential of chatbots for screening and monitoring COVID-19 was envisioned since the outbreak of the disease. Chatbots can help disseminate up-to-date and trustworthy information, promote healthy social behavior, and support the provision of health care services safely and at scale. In this scenario and in view of its far-reaching postpandemic impact, it is important to evaluate user experience with this kind of application.

- Low-grade gliomas make up 30% of pediatric brain tumors, and the success of treatment relies heavily on how much of the tumor is surgically removed, with sodium fluorescein (Na-Fl) being used to assist in this process.
- A study of pediatric patients undergoing tumor removal with Na-Fl showed impressive results in identifying tumor cells and achieving complete resection, supported by a review of existing literature.
- The findings indicate that Na-Fl might be an effective tool for improving surgical outcomes in pediatric low-grade gliomas, but further research, including randomized controlled trials, is needed to confirm its benefits.
Challenges in high-sensitive troponin assay interpretation for intensive therapy.
Rev Bras Ter Intensiva

Cardiac troponins T and I are considered highly sensitive and specific markers for the diagnosis of acute myocardial infarction. Currently, a series of nonprimary cardiac abnormalities may manifest as an elevation in high-sensitive assays. The reduction in their detection limits has allowed earlier diagnosis and the use of evidence-based therapeutic measures; however, this characteristic has increased the spectrum of detectable noncoronary heart diseases, which poses challenges for characterizing acute coronary syndromes and creates a new role for these tests in known disorders in intensive care units, especially sepsis.
View Article and Find Full Text PDFBackground:: Carers of patients with palliative care needs require careful assessment and support to undertake their role effectively. The carer component of palliative care is embedded in complex situations that necessarily focus on the patient.
Aims:: To explore experiences of specialist palliative care nurses in identifying, assessing and planning care to support those looking after patients with palliative care needs.
Background: The kinetics of high-sensitivity troponin T (hscTnT) release should be studied in different situations, including functional tests with transient ischemic abnormalities.
Objective: To evaluate the release of hscTnT by serial measurements after exercise testing (ET), and to correlate hscTnT elevations with abnormalities suggestive of ischemia.
Methods: Patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary angioplasty were referred for ET 3 months after infarction.
Background: Palliative care services are increasingly identifying areas for improvement, then trying to create appropriate changes in response. Nurses in particular are often expected to take leading roles in quality improvement (QI) but are not necessarily trained or supported in these processes.
Methods: A framework approach to change was developed to guide services through a change cycle and delivered via workshops by representatives of three Australian national projects.
Protected and open field tomato crops are economically important for Portuguese agriculture. In 1983, Pseudomonas syringae pv. tomato (Okabe, 1933) Young, Dye & Wilkie, 1978 was first reported affecting protected crops (3) and then later under open field conditions (1).

Methods: Twenty-four fetuses of mothers with either gestational or previous diabetes (cases), and 25 normal fetuses of mothers without systemic disease (control) were examined. Fetuses were examined through prenatal Doppler and color flow mapping.
