Intraventricular third ventricle meningiomas are very rare. Fourteen cases have been previously reported. We present a case of third ventricle meningioma, and discuss aetiology, pathology, symptoms, signs, position in the ventricle, and surgical approaches.

In this article 98 patients with paediatric intraspinal tumours are presented. All were evaluated according to their ages, sex, signs and symptoms. The patients also had radiological and histopathological studies; and the results of surgical, physical medicine and rehabilitation and of radiotherapy are discussed and compared with the results of patients reported in the literature.

The ability of magnetic nanoparticles (MNPs) to transform electromagnetic energy into heat is widely exploited in well-known thermal cancer therapies, such as magnetic hyperthermia, which proves useful in enhancing the radio- and chemo-sensitivity of human tumor cells. Since the heat release is ruled by the complex magnetic behavior of MNPs, a careful investigation is needed to understand the role of their intrinsic (composition, size and shape) and collective (aggregation state) properties. Here, the influence of geometrical parameters and aggregation on the specific loss power (SLP) is analyzed through in-depth structural, morphological, magnetic and thermometric characterizations supported by micromagnetic and heat transfer simulations. To this aim, different samples of cubic Fe3O4 NPs with an average size between 15 nm and 160 nm are prepared via hydrothermal route. For the analyzed samples, the magnetic behavior and heating properties result to be basically determined by the magnetic single- or multi-domain configuration and by the competition between magnetocrystalline and shape anisotropies. This is clarified by micromagnetic simulations, which enable us to also elucidate the role of magnetostatic interactions associated with locally strong aggregation.

A single venous shunt obstructing the aqueductus of Sylvius was treated by interventriculostomy. A passage for CSF was obtained between the third and fourth ventricles. The catheter which was left in the aqueduct collapsed the malformation, possibly preventing a future haemorrhage. A Simple rubber catheter in the aqueduct of Sylvius has been well tolerated by the patient for 15 years.

The clinical and x-ray features of 28 cases of colloid cyst of the third ventricle are described. Colloid cyst is one of the most favourable space-occupying lesions of the brain for successful surgical removal, because an exact pre-operative diagnosis is possible. The surgical approach for colloid cyst of the third ventricle is discussed and the frequency of postoperative seizure is reviewed in 28 cases and compared with the literature.

Magnetic nanocomposites (FeO-MPTMS-PLGA) were synthesized by single oil emulsion method and characterized by transmission electron microscopy (TEM), X-Ray diffraction (XRD), and vibrating sample magnetometer (VSM). Particle size of nanocomposites was between 117 nm and 246 nm. High performance liquid chromatography (HPLC) was used to investigate drug loading (paclitaxel, PTX) and release from FeO-MPTMS-PLGA-PTX nanocomposites. The percentages of drug loading and encapsulation efficiency onto nanocomposites were found as 7.35 and 68.58, respectively. Cytotoxities of free anticancer drug and anticancer drug-loaded nanocomposites were determined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. In vitro cell culture studies indicated that FeO-MPTMS-PLGA-PTX had significant toxicity on MG-63 cancer cells.
