The medical records of 17 dogs diagnosed with spinal arachnoid cysts at North Carolina State University Veterinary Teaching Hospital were retrospectively examined to identify trends in signalment, history, neurological status, treatment, and short- and long-term prognosis. The typical case was that of a nonpainful, progressive ataxia frequently characterized by hypermetria and incontinence. Cysts typically occurred in the dorsal subarachnoid space at the first to third cervical vertebrae of young, large-breed dogs or the caudal thoracic vertebrae of older, small-breed dogs. Although 14 of 15 dogs treated surgically did well in the short term, long-term successful outcomes were achieved in only eight of the 12 dogs that were followed for >1 year. Significant predictors of good, long-term outcome were not identified; however, factors associated with a trend toward a good outcome included <3 years of age, <4 months' duration of clinical signs, and marsupialization as the surgical technique.

Despite knowledge emerging over the last 40 years, the postoperative results after shunt implantation in patients diagnosed with normal-pressure hydrocephalus (NPH) have not improved significantly over the last decade. For that reason predictors have to be identified in order to preoperatively predict outcome. From 1982 to 2000 we prospectively studied 200 patients diagnosed with NPH. From the patients, who were surgically treated by a shunt implantation we reexamined 155 (78%) postoperatively a mean time interval of 7 months. The NPH was graded according to the results of the intrathecal infusion test in an early stage NPH (without brain atrophy) and late stage NPH (with brain atrophy). In our study, we focussed attention on the possible predictors: patients age, length of disease, clinical signs (gait ataxia, dementia and bladder incontinence), aetiology idiopathic/secondary as well as implanted valve type and the value of resistance to cerebrospinal fluid outflow. To measure the outcome we used the NPH recovery rate and as the statistical test the chi(2) according to Pearson. In 80 patients with an early stage NPH (without cerebral atrophy), a short course of disease (<1 year), a slight degree of dementia and an implanted Miethke-Dual-Switch valve were significant predictors for a positive postoperative outcome. The outflow resistance measured in the intrathecal infusion test showed only a minimal relevance to outcome. Those 75 patients with a late state NPH (with cerebral atrophy) had a better outcome when dementia was not present, the outflow resistance was above 20mm Hg/min/ml, the CSF tap-test was positive and a Miethke-Dual-Switch valve was implanted.

Despite emerging knowledge of over 40 years, the postoperative results after shunt implantations in patients diagnosed for normal-pressure hydrocephalus (NPH) have not improved significantly in the last decade. For this reason, predictors have to be identified in order to preoperatively predict the course of disease. From 1982 to 2000, we examined in a prospective study 200 patients diagnosed for NPH. Of the patients who were surgically treated by a shunt implantation we could re-examine 155 (78%) in a mean time interval of 7 months after operation. The NPH was graduated according to the results of the intrathecal infusion test in an early state NPH (without brain atrophy) and late state NPH (with brain atrophy). In the study we focused our attention on the possible predictors: patient's age, length of disease, clinical signs--like gait ataxia, dementia and bladder incontinence, etiology idiopathic/secondary as well as implanted valve type and the value of resistance to cerebrospinal fluid outflow. To measure the outcome we used the NPH recovery rate, as statistical test the chi(2) according to Pearson. In 80 patients with an early stage NPH (without cerebral atrophy) and a short course of disease (<1 year), slightly distinct dementia and an implanted Miethke Dual-Switch valve were significant predictors for a positive postoperative outcome. The outflow resistance measured in the intrathecal infusion test showed only a minimal relevance for the outcome. Those 75 patients with a late state NPH (with cerebral atrophy) had a better outcome when dementia was not present, the outflow resistance was >20 mm Hg.min/ml, the CSF tap test was positive and a Miethke Dual-Switch valve was implanted.

An 11-year-old boy was evaluated for progressive ataxia, cognitive deterioration, and ophthalmoplegia. The child initially presented with abnormal eye movements at the age of 2 months and was noted to have developmental delay at 6 months. At the age of 7 years, he developed ataxia and cognitive impairment, and subsequently manifested dysphagia and incontinence. The pertinent family history included gait difficulty in the paternal grandmother. At the age of 11, his general physical examination was normal. On neurological examination, he had bilateral external ophthalmoplegia, ataxic dysarthria, dysmetria and tremor in the upper extremities, and marked gait ataxia. An ophthalmological evaluation showed no evidence of pigmentary retinopathy. Brain MRI demonstrated cerebellar, brainstem, and cerebral atrophy. An ataxia panel showed 62 repeats in one allele of the SCA2 gene. Most cases of spinocerebellar ataxia type 2 (SCA2) present between 20 years and 40 years, and affected individuals typically have between 34 and 57 CAG repeats. Neonatal cases of SCA2 have been reported in individuals with over 200 CAG repeats. Childhood SCA2 has been reported previously in two patients but not described clinically. This case broadens the spectrum of the clinical features of infantile-onset SCA2 and highlights the importance of considering this diagnosis in infants and children.

For that reason predictors have to be identified in order to predict preoperatively the course of disease. From 1982 until 2000 we examined in a prospective study 200 patients diagnosed for NPH. From the patients, who were surgically treated by a shunt implantation we could reexamine 155 (78%) in a meantime interval of seven month after the operation. The NPH was graduated according to the results of the intrathecal infusion test in an early state NPH (without brain atrophy) and late state NPH (with brain atrophy). In our study, we focussed the attention on the possible predictors: patients age, length of disease, clinical signs--like gait ataxia, dementia and bladder incontinence, aetiology idiopathic/secondary as well as implanted valve type and the value of resistance to cerebrospinal fluid outflow. To measure the outcome we used the NPH-Recovery-Rate, as statistical test the Chi-square according to Pearson. In 80 patients with an early stage NPH (without cerebral atrophy) a short course of disease (< 1 year), a just slight distinct of dementia and an implanted Miethke-Dual-Switch valve were significant predictors for a positive postoperative outcome. The outflow resistance measured in the intrathecal infusion test showed only a minimal relevance for the outcome. Those 75 patients with a late state NPH (with cerebral atrophy) had a better outcome when dementia was not present, the outflow resistance was above 20 mm Hg*min/ml, the CSF tap-test was positive and a Miethke-Dual-Switch valve was implanted.

In order to understand the correlation between the clinical and neuroimaging manifestations and the long-term prognosis in delayed encephalopathy after carbon monoxide (CO) intoxication, we retrospectively reviewed 12 patients who had delayed encephalopathy from 89 patients with CO intoxication. There were 8 men and 4 women, with a mean age of 54.4 +/- 17.2 years (range: 11-79 years). All patients had prominent consciousness disturbance in the acute stage and received high flow of O2 or hyperbaric oxygen therapy. All of them regained consciousness within 1-7 days, but subsequently developed delayed encephalopathy. The delayed encephalopathy occurred from 14 to 45 days after recovery from the acute stage. The clinical manifestations included cognitive impairment, akinetic mutism, sphincter incontinence, gait ataxia and extrapyramidal syndromes such as chorea, dystonia, and parkinsonism. Brain MRI revealed multiple lesions in the subcortical white matter and basal ganglia, mostly in the globus pallidus, and to a lesser degree in the putamen, and caudate. In the follow-up period, sphincter incontinence first disappeared. The cognitive impairment improved greatly in the following few months, but the involuntary movements were improved only slightly. Some patients had persistent neurological sequelae, such as dystonia. Similary, the follow-up brain MRI showed a steady improvement. In conclusion, the delayed encephalopathy usually developed 2 weeks to 1.5 months after the acute phase of CO intoxication. Globus pallidus and subcortical white matter were commonly involved. The neurological manifestations improved and correlated roughly with the neuroimaging changes.

From 1982 until 2000 we examined 200 patients diagnosed with normal-pressure hydrocephalus (NPH) in a prospective study. From the patients who were surgically treated by a shunt implantation we could re-examine 155 (78%) at a mean time interval of 7 months after the operation. NPH differed in severity according to the results of the intrathecal infusion test in an early state NPH (without brain atrophy) and late state NPH (with brain atrophy). In our study, we focused on the possible predictors: patient age; length of disease; clinical signs including gait ataxia, dementia, and bladder incontinence; idiopathic vs. secondary origin; implanted valve type and the resistance of the valve to cerebrospinal fluid outflow. In 80 patients without cerebral atrophy and a short course of disease (< 1 year), a slight amount of dementia and an implanted Miethke Dualswitch-Valve were significant predictors for a positive postoperative outcome. The outflow resistance measured in the intrathecal infusion test showed only minimal relevance for outcome. Seventy-five patients with cerebral atrophy had a better outcome when dementia was not present, outflow resistance was above 20 mmHg/mL/min, the CSF tap-test was positive, and a Miethke Dualswitch-Valve was implanted.

The natural course of multiple sclerosis (MS) is probably more favourable than previously assumed years ago. Since the introduction of interferons in Germany, the establishment and further development of new diagnostic criteria (McDonald criteria), the causal and symptomatic treatment possibilities and initiation of therapy early in the course of the disease have led to a considerable change in the treatment of MS. MS attacks are usually treated with the intravenous administration of high-dosed steroids. When the attack symptoms do not sufficiently subside, plasmapheresis can be considered. For long-term treatment of MS, beta interferon, glatirameracetate and natalizumab are available as basic causal therapy and natalizumab and mitoxantrone are available for escalation therapy. Frequently occurring spasticity, chronic fatigue syndrome, depression, cognitive disturbances, incontinence, pain, ataxia and sexual disorders must be treated symptomatically. Overall, the outpatient treatment of MS is complex and should be carried out with close cooperation between the family doctor, neurological practices and outpatient departments specialized in treating MS.

In this report, we describe the case of two patients with Bickerstaff's brainstem encephalitis (BBE) who developed delirium manifested as emotional incontinence, restlessness, and aggressive behavior from disease onset. Serum anti-GQ1b and anti-GT1a IgG antibodies were detected in both patients. When unusual psychiatric symptoms are observed, in addition to acute ophthalmoplegia and ataxia, neurologists should take into account the possibility of BBE. Brain MRI findings were normal in both patients and SPECT was performed on only patient 1. SPECT of patient 1 showed reversible hypoperfusion in the brainstem, bilateral thalami, and medial frontal lobe. Brain SPECT appears to be useful for detecting lesions of the brainstem as well as the basal ganglia or cerebrum in BBE.

Cavernous angiomas comprise 5-10% of all vascular malformations in the central nervous system, occurring most frequently in the supratentorial region, and 20% of them in the brain stem. According to literature, brain stem cavernous angiomas occur most frequently in the pons (60%), and equally in the mesencephalon (20%) and in medulla oblongata. In clinical evaluation the authors describe the successful removal of a mesencephalic cavernous angioma causing progressive neurological deficits and symptoms. The authors present a case of a 51 year old female, who had developed 1 year prior to her admittance: fatigue, weakness in the right upper limb and fingers, right lower limb ataxia. One month later, her lower right limb developed sensory deficits. The first neurological exploration indicated dysarthria, moderate facial and right hemiparesis, hemihypaesthesia and ataxia. CT and MR imaging indicated multilobulated cavernomas in the mesencephalon. After conservative treatment the patient became almost symptom free, and thus neurosurgical treatment was not discussed. Later on her symptoms fluctuated, but after 6 month she suddenly developed progressive right hemiparesis, right facial weakness, serious dysphasia, and emotional incontinence combined with continuous spastic sobbings. The control MRI showed enlargement of the cavernomas and new extravasation. Surgery was indicated for removing the cavernomas. The left infratentorial, supracerebellar approach revealed a blood engorged cavernoma in the center of the mesencephalon, almost dividing it. The cavernomas and accompanying haematoma was extirpated. The patient's neurological symptoms rapidly improved after surgery, her dysphasia as well as motor weakness have disappeared. Six days after surgery, we discharged a neurologically symptomless and self-supporting patient. The literature and the presented case indicates that the correct timing and proper surgery allows brain stem cavernomas to be safely removed, or significantly bated, which results in the massive regression of neurological symptoms.
