We report a 24-year-old man who presented unilateral multiple cranial nerve involvements followed by progressive paraplegia. The patient expired after developing DIC and pneumonia. Post-mortem examination revealed Ewing's sarcoma originated in the pubic bone with extensive metastases including the clivus which was responsible for his cranial nerve lesions. The patient was well until 24 years of age when he noted an onset of pain and a mass in the pubic region. The histology of the biopsy specimen of the tumor suggested Ewing's sarcoma. He was treated with chemotherapy and local radiation. A year after, he noted an onset of nuchal pain, difficulty in tongue movement, dysarthria, deafness in the left ear, and diplopia. On admission to our hospital in July 1990, neurological examination revealed an alert and intelligent Japanese male in no acute distress. The olfactory to the trigeminal nerves appeared intact. He showed complete abducens nerve palsy, facial weakness, mild deafness, and weakness of the soft palate, the sternocleidomastoid muscle and the tongue, all on the left side. The remainder of the neurological examination was unremarkable except for dysesthesia along the left C8 and Th1 dermatoms. Radiological examination revealed a 10 x 10 cm sclerotic mass in the public bone and a high signal mass lesion between the clivus and the pons in the T2-weighted MRI. His clinical course was complicated by acute paraplegia with anesthesia below the Th4 dermatom, DIC, and respiratory distress due to plural effusion. Post-mortem examination revealed a necrotic and hemorrhagic tumor in the pubic bone. The histology was consistent with Ewing's sarcoma.(ABSTRACT TRUNCATED AT 250 WORDS)

A 51-year-old man presented with headache, vomiting and exophthalmus. Neurological examination revealed anosmia, papilledema, decrease in visual acuity, and disability in ocular movement. MRI showed a huge mass which occupied the whole nasal cavity and compressed the frontal lobe upwards and the eyes laterally. CT revealed an extensive bony destruction of the frontal base and bilateral orbits. The mass was biopsied transnasally, and was histologically diagnosed as olfactory neuroblastoma. It was highly radiosensitive and disappeared with a local irradiation of 40 Gy. Three months later the patient complained of a pain radiating from the neck to the right arm. MRI demonstrated a metastasis at the vertebral body of C5. Local irradiation of 30 Gy was performed. The metastatic lesion was removed, and a bone graft taken from the iliac bone was transplanted via an anterior cervical approach. Three weeks later, however, a hard mass appeared in the right of his neck and was surgically removed. By histological examination, it was also identified as a metastatic neuroblastoma to the cervical lymph node. A week after the removal of the cervical metastatic lesion, the metastasis extended rapidly to the left cervical and the bilateral hilar lymph nodes of the lungs. Chemotherapy was performed with a total doses of 800mg of cyclophosphamide, 1.5mg of vincristine, 40mg of pirarubicin, and 80mg of cisplatin. The lesions disappeared within 7 days. However, the patient died from disseminated intravascular coagulation 10 months after the onset. Olfactory neuroblastoma is usually an intranasal neoplasm, but it rarely extends intracranially and intraorbitally as is shown in our case. Basically, olfactory neuroblastoma is a relatively slow-growing tumor though it has a tendency to develop local recurrences over long periods even after aggressive primary treatment, and accompanied with distant metastases. However, our patient showed a very short survival time. Invasive extension and multiple metastases occurred during a short period, followed by disseminated intravascular coagulation. Combined chemotherapy at the initial treatment may be recommended in such an extensive case.

We analyzed 143 cases of skull base surgery collected from the eight institutions of the Study Group supported by the Grant-in-Aid for Cancer Research from the Ministry of Health and Welfare of Japan. Histologically, the most common type was squamous cell carcinoma (n = 78), which was followed by olfactory neuroblastoma (n = 16) and adenoid cystic carcinoma (n = 16). The most frequent surgical approach was frontal craniotomy (n = 66), followed by front-temporal craniotomy (n = 54) and infratemporal fossa approach (n = 8). For repair of dura matter, fascia lata was used in 37 cases. galeopericranial flap in 35 and temporal muscle fascia in 16. The 5-year survival rate by Kaplan-Meier method of nose and paranasal sinus carcinoma (n = 119) was 48%. As for histological classification, the survival rates were both 65%) in adenoid cystic carcinoma (n = 12) and bone soft tissue malignancy (n = 10), 62% in olfactory neuroblastoma (n = 16), 46% in squamous cell carcinoma (n = 62) and 33% in adenocarcinoma (n = 11). All the three cases of malignant melanoma died within 1 year, so we considered skull base surgery to be contraindicated for this disease. Complications were observed in 62 out of the 143 cases (43%); local infection was most frequent in 29 cases. liquorrhea in 18, abscess in 16, necrosis of the flap and meningitis in ten cases, DIC in four, rupture of the internal carotid artery in two and cerebral thrombosis in one. Death caused directly by surgery was in ten cases (7%). It is important that a multi-center registry be maintained to have a large enough database for comparison of results, and prognosis for each histological entity and further define the role of multidisciplinary treatment.

From the middle of 1990's, there repeated in winter season an outbreak of encephalopathy in Japan that appeared to be associated with influenza. A national survey was conducted, and a total of 507 patients was diagnosed as having influenza-associated encephalopathy during 1998-2002 on the basis of virologic analysis. Type A influenza was more pathogenic than type B, and A: H3 type was more invasive than A: H1 type. Encephalitis developed mainly in children below 5 years of age, either on the day that influenza signs appeared or on the next day. We hypothesized that the replicated viruses at nasopharyngeal epithelium disrupt the olfactory mucosa. Via olfactory nerve system, the stimuli may be transmitted to the brain eventually to activate glial cells, and to induce the production of pro-inflammatory cytokines. The cytokine storm results in neural cell damage as well as apoptosis of glial cells due to TNF-induced mitochondrial respiratory failure. The disruption of blood-brain barrier progresses to the systemic cytokine storm, resulting in DIC and MOF.

There is a substantial body of evidence indicating that new functional neurons are constitutively generated from an endogenous pool of neural stem cells in restricted areas of the adult mammalian brain. Newborn neuroblasts from the subventricular zone (SVZ) migrate along the rostral migratory stream (RMS) to their final destination in the olfactory bulb (OB). In the RMS, neuroblasts migrate tangentially in chains ensheathed by astrocytic processes using blood vessels as a structural support and a source of molecular factors required for migration. In the OB, neuroblasts detach from the chains and migrate radially into the different bulbar layers where they differentiate into interneurons and integrate into the existing network. In this manuscript we describe the procedure for monitoring cell migration in acute slices of the rodent brain. The use of acute slices allows the assessment of cell migration in the microenvironment that closely resembling to in vivo conditions and in brain regions that are difficult to access for in vivo imaging. In addition, it avoids long culturing condition as in the case of organotypic and cell cultures that may eventually alter the migration properties of the cells. Neuronal precursors in acute slices can be visualized using DIC optics or fluorescent proteins. Viral labeling of neuronal precursors in the SVZ, grafting neuroblasts from reporter mice into the SVZ of wild-type mice, and using transgenic mice that express fluorescent protein in neuroblasts are all suitable methods for visualizing neuroblasts and following their migration. The later method, however, does not allow individual cells to be tracked for long periods of time because of the high density of labeled cells. We used a wide-field fluorescent upright microscope equipped with a CCD camera to achieve a relatively rapid acquisition interval (one image every 15 or 30 sec) to reliably identify the stationary and migratory phases. A precise identification of the duration of the stationary and migratory phases is crucial for the unambiguous interpretation of results. We also performed multiple z-step acquisitions to monitor neuroblasts migration in 3D. Wide-field fluorescent imaging has been used extensively to visualize neuronal migration. Here, we describe detailed protocol for labeling neuroblasts, performing real-time video-imaging of neuroblast migration in acute slices of the adult mouse forebrain, and analyzing cell migration. While the described protocol exemplified the migration of neuroblasts in the adult RMS, it can also be used to follow cell migration in embryonic and early postnatal brains.
