We report 13 patients with third ventricular meningiomas (TVM) and discuss the clinical, radiological, pathological and surgical features, as well as follow-up of these tumors. TVM are rare intracranial tumors, and because of this, there are few reports in the literature. Of 11,600 intracranial meningiomas that were surgically treated and pathologically confirmed at Beijing Tian Tan Hospital over a period of 10 years (2003-2013), 13 TVM were selected for a retrospective review. We recorded the clinical, radiological, pathological, and surgical data and statistically analyzed the preoperative, postoperative and 6 month postoperative Karnofsky performance scale (KPS) scores. TVM represented 0.11% of intracranial meningiomas. Radiologically, TVM were divided into three groups: anterior (n=3), posterior (n=3), and entire third ventricle (n=7). Three patients (23.1%) were misdiagnosed preoperatively. Total removal was achieved in 61.5% (8/13) of patients, and subtotal resection was achieved in 38.5% (5/13). Pathologically, the tumors were World Health Organization (WHO) Grade I in 11 patients (84.6%) and WHO Grade II in two (15.6%). There were no statistically significant differences in the preoperative, postoperative, or 6 month postoperative KPS scores (F=0.814; p=0.401). TVM without dural attachments are rare neoplasms that should be differentiated from choroid plexus papilloma, craniopharyngioma, and pineocytoma. Surgery is the optimal treatment and may result in a favorable prognosis, and understanding of the radiological subtype can help with the choice of surgical approach.

Tricuspid Regurgitation in Tuberculous Constrictive Pericarditis Underwent Pericardiectomy.

Department of Cardiology, The Third People's Hospital of Chengdu, The Affiliated Hospital of Southwest Jiaotong University, Chengdu, China.
Background: The presence of constrictive pericarditis (CP) in conjunction with tricuspid regurgitation (TR) and the worsening of TR following pericardiectomy are associated with a reduction in patient survival. The purpose of this study was to investigate the prevalence of tuberculous CP in conjunction with TR, the incidence of worsening regurgitation following pericardiectomy, and the analysis of associated factors.
Methods: Seventy-five consecutive patients who underwent pericardiectomy for tuberculous CP at the institution between January 2021 and December 2023 were retrospectively analyzed.
Treatments for obstructive hydrocephalus secondary to malignant midline intracranial tumors during the perioperative period - a retrospective study of 372 pediatric patients from a single institution.

Objective: Common treatments for obstructive hydrocephalus caused by malignant midline intracranial tumors during the perioperative period include ventriculoperitoneal shunt (VPS) placement, endoscopic third ventriculostomy (ETV), and direct tumor resection. The purpose of this study is to determine whether it is necessary to treat hydrocephalus before tumor resection and to clarify which treatment is most effective.
Methods: Data from 372 pediatric patients (under 18 years) with obstructive hydrocephalus due to malignant midline intracranial tumors, referred to the Department of Pediatric Neurosurgery at Beijing Tiantan Hospital between January 2018 and September 2019, were collected.
Primary Leptomeningeal Lymphoma Presenting As Rapidly Progressive Hydrocephalus: Diagnosis and Symptom Relief Through Endoscopic Ependymal Biopsy and Third Ventriculostomy.

Primary leptomeningeal lymphoma (PLML) is a rare variant of primary central nervous system lymphoma, distinguished by the absence of parenchymal lesions. We describe an exceptionally rare case of PLML in an 86-year-old woman presenting with hydrocephalus. Magnetic resonance imaging showed ventricular enlargement over a two-week period, accompanied by faint periventricular contrast enhancement.

Measurement of the ventricular action potential (AP) via whole-cell patch clamp is an important contributor to cardiac electrophysiological research. Neonatal rat ventricular cardiomyocytes (NRVCM) are a commonly used model, in particular for stressor- or drug-related questions. High variability of APs and individual methodological settings hinder comparison both in individual studies and, to an even greater degree, between different projects.

Objectives: To evaluate the diagnostic yield of screening outpatients at risk for HF using a noninvasive assessment of left ventricular end-diastolic pressure (LVEDP) and to describe the health status of patients newly identified with elevated LVEDP.
Methods: A convenience sample of adults with diabetes mellitus (DM), chronic kidney disease (CKD), or suspected HF were screened at three primary care clinics using the Vivio System to identify patients with LVEDP >18 mmHg (positive screening).
