    Inflammatory changes have been found in Parkinson's disease, in humans intoxicated with the parkinsonian toxin MPTP, and in animal models of the disease. However, it is still not known whether inflammatory changes are responsible for active nerve cell death or if they have a protective role against neurodegeneration. In this study, we analyzed the glial reaction in the substantia nigra pars compacta (SNpc) and the striatum of monkeys rendered parkinsosian by chronic MPTP injections. At ...

    OBJECTIVE: Pneumocephalus is a well-known complication of surgical procedures performed with the patients placed in the sitting position. Its incidence and intensity were prospectively studied in 90 consecutive patients undergoing a posterior fossa procedure in this position. Various anesthetic agents, with different effects on cerebral hemodynamics, were used.

    MATERIAL AND METHODS: Patients were randomly assigned to one of three groups. In group 1 (n=30), anesthesia was induced and ...

    BackgroundGrisel's syndrome is a uni- or bilateral subluxation of the atlas on the axis associated with an inflammatory condition of the head or neck. This uncommon entity usually affects children. The condition seems to be secondary to hyperemia and laxity of the atlanto-axial joints.Patients and methodsWe report clinical and neuroimaging findings, treatment modalities, and outcomes in 4 children with atlanto-axial rotatory subluxation (AARS) associated with a previous upper respiratory ...

    Abstract. The formation of an epidural hematoma from an eosinophilic granuloma of the skull is an exceptional occurrence. A 9-year-old boy presented with severe headache, somnolence and vomiting following a minor head injury. Cranial computerized tomography scan showed a seemingly depressed skull fracture together with an epidural hematoma in evolution. A neoplasm and an epidural hematoma were removed at operation. Histopathological study of the excised mass confirmed the diagnosis of ...

    OBJECT: Most craniocerebral injuries are caused by mechanisms of acceleration and/or deceleration. Traumatic injuries following progressive compression to the head are certainly unusual. The authors reviewed clinical and radiological features in a series of patients who had sustained a special type of cranial crush injury produced by the bilateral application of rather static forces to the temporal region. Their aim was to define the characteristic clinical features in this group of ...

    Abstract Ventriculoperitoneal shunting constitutes the standard procedure for draining cerebrospinal fluid (CSF) in children with hydrocephalus. Ventriculoatrial and ventriculopleural shunting are alternative methods of CSF drainage, which have gained less acceptance. Ventriculopleural shunts are seldom used owing to justified fears of pneumothorax and symptomatic effusions of CSF. The addition of an antisiphon device to standard shunt systems seems to have prevented CSF pleural ...

    Two siblings presented with macrocephaly, psychomotor delay, and progressive dystonia. The initial diagnosis was of hydrocephalus and bilateral temporal cerebrospinal fluid collections. Following ventriculoperitoneal shunting, the patients showed only modest neurological improvement. Metabolic investigations performed later in the course of the disease disclosed increased levels of glutaric acid in the urine and decreased levels of serum carnitine, which were confirmatory of glutaric ...

    BACKGROUND: In most cases, craniosynostosis is a sporadic occurrence of unknown etiology. Efforts to ascertain the exact, cause of this deformation often fall to reveal its origin and pathogenetic mechanism. Some previous reports have described isolated instances of the association of neural tube defects (NTD) and craniosynostosis, but in none of them has a causal relationship been established to explain this coincidence, apart from a fortuitous sequence of congenital defects.

    Abstract Most cases of craniosynostosis are diagnosed during early infancy, but occasionally craniosynostosis evolves with minimal cranial involvement and goes unnoticed until late childhood. Seemingly these mild forms of craniosynostosis cause few, if any, symptoms of neurological involvement. We describe the cases of a 9-year-old girl and a 6-year-old boy who presented with evident signs of raised intracranial pressure (ICP), together with a negligible skull deformity. We have termed ...

    Summary. Atlanto-axial rotatory subluxation (AARS) is an uncommon condition involving dislocation and abnormal fixation of the atlas on the axis. AARS is difficult to diagnose and if improperly treated it may lead to permanent neck deformity. We report a retrospective series of patients diagnosed with AARS seen during the last five years. The children presented with neck pain, head tilt, and reduction in neck mobility. In three of the cases the condition was secondary to cervical trauma ...

    Atretic cephalocele appears as an unimportant and benign lesion. This malformation consists of meningeal and vestigial tissues (arachnoid, glial, or central nervous system rests). The authors report the findings in 16 cases (seven parietal and nine occipital) of rudimentary cephaloceles. Twelve patients presented with associated brain abnormalities detected by either computerized tomography (CT) or magnetic resonance imaging (MR). Nine lesions also exhibited an anomalous vascular ...

    The parkinsonian symptoms of primates after MPTP exposure can be measured by several visual methods (classical motor scores). However, these methods have a subjective bias, especially as regards the evaluation of the motor activity. Computerized monitoring systems represent an unbiased method for measuring the motor disability of monkeys after MPTP administration. In this work the motor activity of monkeys before and after MPTP administration is measured and compared with the activity of ...

    Dermoid tumours in children usually occur in two locations: at the anterior fontanelle and on the occipital squama. An exceptional site of origin for a posterior fossa dermoid cyst is the extradural space. There are only six previous cases of this situation reported in the literature. A series of 103 subscalp and calvarial masses in children were reviewed and three children are reported with extradural dermoids of the posterior fossa, which communicated with the skin through midline ...

    A 16-month-old male infant presented with paraparesis and a high thoracic skin dimple. After myelography the child underwent complete surgical removal of the dermal sinus and of an abscessed tumor located within the cervicothoracic cord. Histological study showed that the lesion was an intramedullary epidermoid cyst. Only four descriptions have previously been published of dermal sinuses associated with intramedullary epidermoids, three of them complicated by intramedullary abscesses. ...

    IntroductionLumbar disc herniation is a common condition in adults, uncommon in adolescents and exceptional below the age of 10 years.Case reportWe report on a 6-year-old boy who presented with low-back pain and sciatica after having sustained an injury in a rear-end automobile accident. Due to our limited experience with protruded discs in this age group, we decided to be conservative initially. However, the persistence of incapacitating pain prompted surgical treatment. Operative ...
