Case Report: Chemotherapy Indication in a Case of Neurofibromatosis Type 1 Presenting Optic Pathway Glioma: A One-Year Clinical Case Study Using Differential Tractography Approach.

Neurofibromatosis type 1 (NF1) is associated with peripheral and central nervous system tumors. It is noteworthy that the regions in which these tumors frequently arise are the optic pathways (OPs) and the brainstem. Thus, we decided to trace the procedure of diffusion Magnetic Resonance Imaging (dMRI) alterations along with Short-Wavelength Automated Perimetry (SWAP) examinations of the OPs after surgery and chemotherapy over 1 year, which enabled us to evaluate chemotherapy's efficacy in an NF1 patient with an OP tumor.

Glioma Migration Through the Corpus Callosum and the Brainstem Detected by Diffusion and Magnetic Resonance Imaging: Initial Findings.

: Glioma cell infiltration, in which the glioma tumor cells spread long distances from the primary location using white matter (WM) or blood vessels, is known as a significant challenge for surgery or localized chemotherapy and radiation therapy. Following the World Health Organization (WHO), the glioma grading system ranges from stages I to IV, in which lower-grade gliomas represent benign tumors, and higher grade gliomas are considered the most malignant. : We gathered magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) data for seven patients with right precentral gyrus-located tumors and six age- and sex-matched healthy subjects for analysis.

Concomitant ligamentous and meniscal knee injuries in femoral shaft fracture.

Background: Concomitant knee injury is a common finding in femoral fractures but can be easily missed during early management of the initial trauma. Degrees of damage to the articular structures vary considerably; from only a mild effusion to complete ligamentous and meniscal tears. Since previous reports were mostly from developed societies, this study was designed to look into characteristics of associated knee injury in a sample from Iran, to represent a developing country perspective.

Comparison of the effect of endoscopic sinus surgery versus medical therapy on olfaction in nasal polyposis.

Chronic rhinosinusitis is a common inflammatory condition in western countries. Nasal polyposis has different symptoms such as nasal obstruction, anterior or posterior nasal drip, reduced sense of smell, and facial pain. Medical and endoscopic treatments are the two main treatments for nasal polyposis.

Percutaneous transvenous mitral commissurotomy in a patient with situs inversus and dextrocardia: a case report.

Background: Dextrocardia situs inversus refers to the heart being a mirror image situated on the right side of the body. Distorted cardiac anatomy provides technical difficulties during fluoroscopy-guided transcatheter procedures. This is even more difficult in the case with percutaneous transvenous mitral commissurotomy (PTMC).

Clinical outcome and cost in patients with off-pump vs. on-pump coronary artery bypass surgery.

General concept and major emphasis on off-pump coronary artery bypass surgery (OPCAB) is maintaining quality of care and patient safety while reducing cost and resource utilization. OPCAB probably avoids the potential complications of cardiopulmonary bypass. However its acceptance depends on clinical and economic outcome.
