A neuroanatomical study of the feline brain using MRI and mulligan staining: functional and pathological considerations.

BACKGROUND: Despite multiple studies describing accurate diagnoses using advanced neuroimaging techniques, low and mid-field magnetic resonance imaging (MRI) are still the most frequent scanners in veterinary clinics. To date, these studies in cats do not show a clear distinction of nerve centres in MRI data. AIMS: The objective of this study is to determine the efficacy of Mulligan histological staining as a tool in facilitating the location and identification of the main structures of the feline brain in MRI. This study aims to facilitate the interpretation of MRI obtained with these types of scanners. METHODS: A total of 10 feline brains were used. One specimen was used for MRI (T2 sequence using a 1.5T scanner). The other 9 brains were sectioned and stained with the three Mulligan staining techniques (Mulligan, Le Masurier and Robert). RESULTS: The uptake of stain by the grey matter in these sections allowed the determination of the location and the limits of these nervous structures within the brain. The histological location of these structures was correlated with the MRI scans, leading to the successful identification of many small, indistinct nuclei. CONCLUSION: Mulligan staining is proposed as a tool that facilitates the location of nerve structures in comparison with data from the most frequently-used MRI scanners in veterinary clinics.

[Lemierre's syndrome: septic thrombophlebitis of the internal jugular vein secondary to acute amygdalitis]. / Síndrome de Lemierre: tromboflebitis séptica de la yugular interna secundaria a amigdalitis aguda.

Lemierre's syndrome is an uncommon clinical entity. It consists of an acute oropharyngeal infection, with secondary septic thrombophlebitis of the internal jugular vein frequently complicated with multiple metastatic infections. It is generally caused by anaerobic Gram-negative organisms. Although it is rarely reported in the antibiotic era, this disease must be taken into account because it is a potentially life-threatening infection requiring a specific and early treatment. We report a case of Lemierre's syndrome managed in our hospital.

Síndrome de Lemierre: Tromboflebitis séptica de la yugular interna secundaria a amigdalitis aguda / Lemierre's syndrome: septic jugularis interna thrombophlebitis secondary to acute amigdalitis

El síndrome de Lemierre es un cuadro poco frecuente en la actualidad. Consiste en una tromboflebitis séptica de la vena yugular interna, con frecuentes metástasis sépticas, secundaria a una infección faríngea u odontógena producida generalmente por gérmenes Gram-negativos anaerobios. Aunque su incidencia es escasa en la era antibiótica, debe ser conocido por tratarse de una complicación grave que requiere la instauración de un tratamiento específico precoz.

Determination of the object surface function by structured light: application to the study of spinal deformities.

The projection of structured light is a technique frequently used to determine the surface shape of an object. In this paper, a new procedure is described that efficiently resolves the correspondence between the knots of the projected grid and those obtained on the object when the projection is made. The method is based on the use of three images of the projected grid. In two of them the grid is projected over a flat surface placed, respectively, before and behind the object; both images are used for calibration. In the third image the grid is projected over the object. It is not reliant on accurate determination of the camera and projector pair relative to the grid and object. Once the method is calibrated, we can obtain the surface function by just analysing the projected grid on the object. The procedure is especially suitable for the study of objects without discontinuities or large depth gradients. It can be employed for determining, in a non-invasive way, the patient's back surface function. Symmetry differences permit a quantitative diagnosis of spinal deformities such as scoliosis.
