Primary bulbo-medullary glioblastoma in a child: case report.

Glioblastoma (GBM) of the spinal cord represents a rare entity in children and account for less than 1% of all central nervous system (CNS) cancers. Their biology, localization, and controversial treatment options have been discussed in a few pediatric cases. Here, we report a case of primary spinal cord glioblastoma in a 5-year-old girl having the particularity to be extended to the brainstem.

Nonlinear Cascade Strategy for Longitudinal Control of Electric Vehicle.

The problem of controlling the longitudinal motion of front-wheels electric vehicle (EV) is considered making the focus on the case where a single dc motor is used for both front wheels. Chassis dynamics are modelled applying relevant fundamental laws taking into account the aerodynamic effects and the road slope variation. The longitudinal slip, resulting from tire deformation, is captured through Kiencke's model.

Intracerebellar haematoma simulating congenital medulloblastoma during neonatal period.

The authors report a case of intracerebellar haematoma occurring during the neonatal period. A 5-day-old baby girl was admitted because of poor feeding and the anterior fontanelle was tense. CT scan of the brain revealed a round mass at the cerebellar vermis; the lesion simulated a cerebellar tumour such as a medulloblastoma.

[Synovial cyst of cervical spine].

The synovial cyst is a rare cause of cervical medullar compression. We report on one case of a 74-year-old man hospitalized for electric discharge in the limbs at neck extension. The MRI and CT-scan revealed a posterior extradural cystic lesion at the level of C5-C6.

[Intracranial granuloma: a rare complication of ventricular derivation. Case report].

We report an unusual case of cerebral granuloma secondary to ventriculoperitonal shunt. A 17 year-old patient presented with choreoathetoid movements of the left upper limb five years after a ventriculoperitoneal shunt and cerebellar pilocytic astrocytoma excision procedure. MR imaging showed mass lesion in right basal ganglia area surrounding ventricular catheter which seems to be neoplastic.

[Colonic Crohn's disease complicated with peripheral neuropathy].

The association of Crohn's disease and peripheral neuropathy is a rare event and the pathogenic factors often implicated are vitamin B12 deficiency or metronidazole treatment. We report a case of severe axonal polyneuropathy associated with Crohn's disease and unrelated to vitamin deficiency or metronidazole treatment. This represents a very rare extra-digestive manifestation of Crohn's disease.

[A case of diffuse inflammatory colonic pseudopolyposis caused by Crohn's disease].

Inflammatory pseudopolyposis of the colon is an uncommon anatomoclinical entity. It is generally associated with ulcerative colitis, Crohn's disease or schistosomiasis. We report a case of a pseudopolyposis in Crohn's disease involving the entire colon.

Pathophysiological study of diarrhoea in a patient with medullary thyroid carcinoma. Evidence against a secretory mechanism and for the role of shortened colonic transit time.

Intubation techniques and scintigraphic studies were used to determine the origin and mechanism of diarrhoea in a patient with medullary thyroid carcinoma, high plasma immunoreactive calcitonin and normal circulating serotonin, substance P and prostaglandins E2 and F2 alpha. Normal function of the small intestine was found for the following: (a) absorption tests; (b) water and electrolyte absorption in the proximal jejunum; (c) 24 hour flow rate and composition of fluid entering the colon and (d) gastric emptying rate and small intestinal progression of a normal meal. By contrast, colonic function was markedly impaired in three ways: (a) water absorption was decreased by half; (b) as the main excreted solutes were organic acids, a large electrolyte gap was recorded in faecal water, and (c) colonic transit time of the meal marker was very short, and was in agreement with the rapid transit of ingested radioopaque markers.
