    We sought to determine the analgesic efficacy, opioid-sparing effects, and tolerability of propacetamol, an injectable prodrug of acetaminophen, in combination with morphine administered by patient-controlled analgesia (PCA) after spinal fusion surgery. Forty-two patients undergoing spinal stabilization surgery were randomized into two groups, which were given either an IV placebo or an IV injection of 2 g propacetamol every 6 h for 3 days after surgery. The postoperative opioid ...

    BACKGROUND: Some reports have documented posterior fossa cysts resulting in syringomyelic obstruction of cerebrospinal fluid (CSF) flow caused by cyst displacement within the foramen magnum. Rarely the syringomyelia is caused by acquired Chiari malformation due to a retrocerebellar arachnoid cyst.

    OBJECTIVE: To report the case of a 38-year-old man with hydrocephalus and syringomyelia, who was found to have a Chiari malformation secondary to a posterior fossa arachnoid cyst. After ...

    BackgroundEmbryonal central nervous system (CNS) tumors are currently classified into three types: medulloblastoma, atypical rhabdoid/teratoid tumors, and primitive neuroectodermal tumor (PNET). A distinctive subtype of PNET called “embryonal tumor with abundant neuropil and true rosettes” (ETANTR) was reported in 2000.DiscussionETANTR is a recently described variety of PNET that combines microscopic features of neuroblastoma and ependymoblastoma, demonstrating areas of fine fibrillary ...

    BackgroundPatients with craniosynostosis are readily diagnosed by clinical and neuroimaging findings. Surgical treatment is indicated for preventing neurological deficits and for correcting esthetically unacceptable head deformities. In recent years, we have witnessed a progressive number of neurosurgical consultations for abnormal head shapes unrelated to premature fusion of the cranial sutures, especially of positional plagiocephaly. There have been descriptions of abnormalities in the ...

    The objective of this study was to analyze the association of cerebellar tonsillar descent and syringomyelia in patients with posterior fossa arachnoid cysts. We reviewed the medical records of ten patients (mean, age 33; range, 24–49 years) diagnosed with posterior fossa arachnoid cyst and tonsillar descent. Symptoms evolved over a mean of 12 months (range, 6 months to 3 years). Syringomyelia was present in six cases. Six patients underwent a suboccipital craniectomy, three cases ...

    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 ...

    AimsThe aims of this study are the following: first, to analyze incidence, trends, and survival of nervous system tumors in children under the age of 15 in the Region of Murcia, Spain, during the years 1998–2009 and second, to evaluate if certain environmental exposures may be involved in the etiology of childhood nervous system tumors. The study was performed on the spatial and temporo-spatial distribution of the observed cases.MethodsThe Environment and Pediatric Cancer in the Region ...

    BackgroundCerebrospinal fluid (CSF) overdrainage in hydrocephalus is well recognized. Overshunting following cysto-peritoneal (CP) drainage in patients with arachnoid cysts (AC) is rarely documented.AimWe report five patients with acquired Chiari malformation I and three with posterior fossa overcrowding due to excessive CSF drainage in shunted intracranial ACs. We review our observations and discuss the current knowledge on the pathogenesis and management of this complication.Patients ...

    BackgroundDiverse materials have been used for dural closure, including grafts of cadaveric origin. Some 168 cases of Creutzfeldt–Jakob disease have been reported following the implant of human dura mater. A few publications have addressed the use of dural grafts in children, but none has analyzed the feasibility of autologous tissues for this purpose.AimSince 1994, the authors have utilized autologous tissues for dural grafting in children undergoing neurosurgical procedures, aimed at ...

    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 ...

    The objective of this article is to assess the safety of intraspinal infusion of autologous bone marrow mononuclear cells (BMNCs) and, ultimately, to look for histopathological signs of cellular neurotrophism in amyotrophic lateral sclerosis (ALS) patients. We conducted an open single arm phase I trial. After 6 months observation, autologous BMNCs were infused into the posterior spinal cord funiculus. Safety was the primary endpoint and was defined as the absence of serious ...

    Niikawa-Kuroki, or Kabuki syndrome (KS), is characterized by distinctive facial features, skeletal anomalies, persisting fingertip pads with dermatoglyphic abnormalities, short stature, and mental retardation. Neurological manifestations and CNS anomalies have been described in some patients with this condition. However, craniosynostosis has been documented in only 4 patients with KS who did not undergo operations. The authors report a case of KS with unicoronal synostosis that ...

    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 ...

    Arachnoid cysts situated in the middle cranial fossa constitute the largest group of this type of lesion. Their origin has been the subject of debate since they were first described. There is still controversy as to whether they originate directly from the meninges adjacent to the temporal pole or whether partial agenesis of the temporal lobe favours secondary formation of the cyst. We assessed the morphology of the temporal lobe and the bulging of the squamous temporal bone. ...
