[A case of cryptogenic new-onset refractory status epilepticus (NORSE) in which cerebrospinal fluid IL-6 was elevated with increased seizure frequency early in the disease: a case report].

A 25-year-old male presented with clonic seizures three days following a fever. The patient developed status epilepticus and required mechanical ventilation and intravenous anesthesia. The patient's epileptic seizures persisted despite administering intravenous anesthesia and multiple anti-epileptic drugs. The clinical presentation in this case, without pre-existing relevant neurological disorder and an active structural, toxic, or metabolic cause in the acute phase, was compatible with new-onset refractory status epilepticus (NORSE). After immunotherapy, including intravenous methylprednisolone, plasma exchange, and intravenous immunoglobulin therapy, the epileptic discharge on electroencephalogram (EEG) decreased gradually, and mechanical ventilation was discontinued. Neversless the final outcome was poor. The patient's condition was finally diagnosed as cryptogenic NORSE. The IL-6 levels in the cerebrospinal fluid showed a significant increase between day 6 and 11 after onset, during which time there was a rapid escalation in seizure frequency on EEG. Considering this, IL-6 may be involved in the process of seizure exacerbation.

A case of sphenoid sinus meningoencephalocele repaired by an image-guided endoscopic endonasal approach.

We report a Japanese patient with a complaint of unilateral watery nasal discharge. Analysis of the nasal discharge showed it to contain high levels of sugar and transferrin, which indicated cerebrospinal fluid (CSF) rhinorrhea. A diagnosis of sphenoid sinus meningoencephalocele was easily made on the basis of the CT, MRI and nasal discharge findings. We performed surgery by an image-guided endoscopic endonasal approach (IGEEA). An image guidance system (IGS) was used to confirm the position of the bone defect and the prolapsed brain lobe. We resected the brain lobe, and used fat tissue and fascia to create an extracranial-intracranial blockade. As of 18 months after the operation, there is no evidence of infection or CSF leakage. The IGEEA enabled us to successfully repair the middle skull base using a multi-layer sealing technique, while the IGS allowed us to confirm the anatomical structures and successfully avoid causing collateral damage to the surrounding tissues. This case exemplifies the beneficial effect that of the development of surgical support equipment on the operative approach that is now indicated for sphenoid sinus meningoencephaloceles: the endonasal approach has largely replaced other approaches, such as lateral rhinotomy.

Low-frequency rTMS with language therapy over a 3-month period for sensory-dominant aphasia: case series of two post-stroke Japanese patients.

PURPOSE: To examine the safety and feasibility of therapeutic application of low-frequency repetitive transcranial magnetic stimulation (rTMS) combined with language therapy for post-stroke patients with sensory-dominant aphasia. SUBJECTS AND METHODS: Two post-stroke Japanese patients with sensory-dominant aphasia were studied. In both patients, 10 sessions of 20-minute low-frequency rTMS with 1 Hz to the Wernicke's area were provided throughout 6-day hospitalization, followed by weekly outpatient rTMS treatment for 3 months. The language therapy was also provided through the period of in- and out-patient treatment. Language function was evaluated using the Token test and the Standard Language Test of Aphasia (SLTA) at the start and end of the in-patient treatment and the end of the outpatient treatment. RESULTS: The therapeutic protocol was well tolerated throughout the in- and out-patient treatments, without any adverse effects. The scores of the Token test and certain sub-categories of SLTA increased in both patients after the in-patient rTMS treatment. Persistent improvement of the score was noted over the 3-month post-discharge period. CONCLUSIONS: The proposed protocol of long-term application of low-frequency rTMS to the Wernicke's area and language therapy is considered a safe and feasible therapeutic approach for post-stroke patients with sensory-dominant aphasia.

Six-day course of repetitive transcranial magnetic stimulation plus occupational therapy for post-stroke patients with upper limb hemiparesis: a case series study.

PURPOSE: To clarify the safety and feasibility of a 6-day protocol of low-frequency repetitive transcranial magnetic stimulation (rTMS) combined with intensive occupational therapy (OT) for upper limb hemiparesis. METHODS: In-hospital combination treatment was provided for 5 post-stroke patients with upper limb hemiparesis after more than 12 months of the onset of stroke. Over 6 consecutive days, each patient received 10 sessions of combination treatment with 1 Hz rTMS and intensive OT (one-on-one training and self-training). Motor function in the affected upper limb was evaluated by Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT), Ten-Second Test at admission, discharge, and 4 weeks after treatment. RESULTS: All patients completed the 6-day treatment protocol and none showed any adverse effects throughout the treatment. At the end of treatment, improvements in the scores of FMA, WMFT, and Ten-Second Test were found in all patients. No deterioration of improved upper limb function was observed at 4 weeks after the treatment. CONCLUSIONS: Our proposed protocol of combination treatment seems to be safe and feasible for post-stroke patients with upper limb hemiparesis, although the efficacy of the protocol needs to be confirmed in a large number of patients.

Functional MRI-based therapeutic rTMS strategy for aphasic stroke patients: a case series pilot study.

Four poststroke patients with motor-dominant aphasia received 10 treatment sessions of low-frequency repetitive transcranial magnetic stimulation (rTMS). Each treatment session consisted of 1,200 pulses of stimulation and the site of stimulation was an area homologous to the most activated site on functional MRI performed prior to rTMS. Consequently, rTMS was applied to the right frontal lobe in two patients and to the left frontal lobe in two patients. Treatment resulted in improvement of language function in all four patients. Our therapeutic rTMS strategy seems to be a clinically feasible neurorehabilitative approach for poststroke aphasic patients.

A case of progressive myelopathy with atlas hypoplasia in an infant: controversy in the surgical strategy.

CASE REPORT: The authors report a case of isolated atlas hypoplasia in an 18-month-old infant who experienced delayed motor development confined to the lower extremities, in the absence of other clinical features. Nonetheless, MRI revealed the upper cervical cord to be highly compressed with a high signal intensity lesion apparent at the craniovertebral junction. The patient underwent atlas laminectomy in addition to occipital decompression, resulting in a good neurological recovery. DISCUSSION: We speculate on the significance of this unique clinical presentation and discuss surgical strategies for this condition.

Neuroendoscopic placement of Ommaya reservoir into a cystic craniopharyngioma.

INTRODUCTION: Total removal of the tumor is the most acceptable therapeutic modality in the management of craniopharyngioma; however, there are innumerable factors that can upset treatment plans. Unresectable lesions are often treated with gamma knife surgery (GKS). Reduction of the cystic volume is necessary, to decrease the area to be treated with GKS. An Ommaya reservoir system is usually placed during open surgery or by stereotactic access. MATERIALS AND METHODS: The authors use a neuroendoscope for safer and less invasive placement of the Ommaya reservoir into deep-seated cystic lesions. The cystic component is aspirated, and the Ommaya reservoir tube is precisely guided and placed into the cyst cavity under neuroendoscopic control with a newly developed two-burr-hole technique. This neuroendoscopic procedure could make it easier to reduce cystic volume prior to GKS as the final procedure. This technique may also be used for instillation of chemotherapeutic agents and for repeat aspirations, making the achievement of cystic control more likely. This type of neuroendoscopic management is a safe and effective procedure and could be considered as an alternative management technique for some stubborn cystic craniopharyngiomas.
