Abstract
OBJECTIVE Spinal intramedullary ependymomas (IEs) represent a well-defined tumor entity usually warranting resection. Factors that determine full long-term neurological recovery after resection are seldomly reported on in larger clinical series. In this study, the authors aimed to highlight the neurological outcome of patients with IEs after resection, with a focus on full neurological recovery, and to explore possible risk factors for the absence of neurological amelioration to an optimal function after surgical treatment. METHODS A single-center retrospective analysis of all patients undergoing surgery for IEs between 2007 and 2021 was performed. Data collection included patient demographics, symptoms, clinical findings, histopathological diagnosis, surgical procedures, complications, and neurological outcome. Patients harboring a favorable outcome (modified McCormick Scale [mMS] grade of I) were compared with patients with a less favorable outcome (mMS grade ≥ II) at the final follow-up. RESULTS In total, 72 patients with a histologically diagnosed IE were included. IEs in those patients (41 males, 31 females; median age 51 [IQR 40-59] years) mostly occurred in the cervical (n = 40, 56%) or thoracic (n = 23, 32%) spine. Upon admission, motor deficits or gait deficits (mMS grade ≥ II) were present in 29 patients (40%), with a median mMS grade of II (IQR I-II). Gross-total resection was achieved in 60 patients (90%), and the rate of surgical complications was 7%. Histopathologically, 67 tumors (93%) were classified as WHO grade 2 ependymomas, 3 (4%) as WHO grade 1 subependymomas, and 2 (3%) as WHO grade 3 anaplastic ependymomas. After a mean follow-up of 863 ± 479 days, 37 patients (51%) had a fully preserved neurological function and 62 patients (86%) demonstrated an mMS grade of I or II. Comparison of favorable with unfavorable outcomes revealed an association of early surgery (within a year after symptom onset), the absence of ataxia or gait disorders, and a low mMS grade with full neurological recovery at the final follow-up. A subgroup of patients (n = 15, 21%) had nonresolving deterioration at the final follow-up, with no significant differences in relevant variables compared with the rest of the cohort. CONCLUSIONS The data presented solidify the role of early surgery in the management of spinal IEs, especially in patients with mild neurological deficits. Furthermore, the presence of gait disturbance or ataxia confers a higher risk of incomplete long-term recovery after spinal ependymoma resection. Because a distinct subgroup of patients had nonresolving deterioration, even when presenting with an uneventful history, further analyses into this subgroup of patients are required.

Abstract
A 58-year-old woman, who had undergone total gastrectomy for early gastric cancer 9 years previously, visited the outpatient clinic complaining of progressive difficulty in walking for 15 d. Laboratory examinations showed macrocytic anemia and a decreased serum vitamin B12 concentration and increased serum concentrations of folate, vitamin E and copper. Magnetic resonance imaging showed multifocal high signal intensities along the posterior column of the cervical and thoracic spinal cord. Treatment consisted of intramuscular injections of vitamin B12 for 7 d, which increased her serum level of vitamin B12 to normal. This was followed by weekly intramuscular injections of vitamin B12 for another 2 wk and oral administration of vitamin B12 three times per day. After comprehensive rehabilitation for 4 wk, she showed sufficient improvements in strength and ataxic gait, enabling her to return to her normal daily activities.

Abstract
To treat the neurogenic bladder-due detrusor/urethral rhabdosphincter dyssynergia, early combined clean intermittent catheterization/ pharmacotherapy (anticholinergic-, β3-adrenoceptor agonist drugs) management may be at times crowned with success of preserving an adequate bladder compliance and renal safe conditions.The persistence, instead, of elevated bladder filling pressure levels with high voiding pressure/uroflow values, together with aberrant urethral rhabdosphincter electromyographic findings, make necessary the resort to surgery strategies, among which - a part from rhabdosphincterotomy or alternatively intrasphincteric botulinum A toxin injection or urethral stent insertion - the bladder augmentation cystoplasty, with either reconfigurated bowel- or gastric segment, is today the most efficacious surgical measure to increase the bladder urinary storage meanwhile lowering bladder filling pressure. Given the enterocistoplasty-dependent both potential systemic metabolic imbalances - such as hyperchloremic acidosis/hypokaliemia, hyperoxaluria, bone demineralization, chologenic diarrhoea/steatorrhoea, vit B12 deficiency - together with bowel prosthetic mucus overproduction-due recurrent stone formation, and, sometimes, malignant complications particularly at the intestinal-urinary tract suture line, tissue engineering techniques have been taken into consideration, more than twenty years ago, as alternative measure for bladder augmentation cystoplasty, until to reach successful clinical validation just in patients suffering from either congenital dysraphism- or acquired spinal cord injury-dependent neurogenic bladder. Nevertheless, also the tissue engineering-made augmentation cistoplasty, as well as that bowel-based one, unfortunately remains influenced by spinal cord neuropathydue dysfunctional effects, hence the tissue engineering research could be today directed to suitably overcome such disadvantageous conditions.

Abstract
BACKGROUND Disabling tremor or ataxia is common in multiple sclerosis (MS) and up to 80% of patients experience tremor or ataxia at some point during their disease. A variety of treatments are available, ranging from pharmacotherapy or stereotactic neurosurgery to neurorehabilitation. OBJECTIVES To assess the efficacy and tolerability of both pharmacological and non-pharmacologic treatments of ataxia in patients with MS. SEARCH STRATEGY The following electronic resources were searched: Cochrane MS Group trials register (June 2006), the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2, 2006), National Health Service National Research Register (NRR) including the Medical Research Council Clinical Trials Directory (Issue 2, 2006), MEDLINE (January 1996 to June 2006), and EMBASE (Jan 1988 to June 2006). Manual searches of bibliographies of relevant articles, pertinent medical and neurology journals and abstract books of major neurology and MS conferences (2001-2006) were also performed. Direct communication with experts and drug companies was sought. SELECTION CRITERIA Blinded, randomised trials which were either placebo-controlled or which compared two or more treatments were included. Trials testing pharmacological agents must have had both participant and assessor blinding. Trials testing surgical interventions or effects of physiotherapy, where participants could not have been blinded to the treatment, must have had independent assessors who were blinded to the treatment. Cross-over trials were included. DATA COLLECTION AND ANALYSIS Three independent reviewers extracted data and the findings of the trials were summarised. A meta-analysis was not performed due to the inadequacy of outcome measures and methodological problems with the studies reviewed. MAIN RESULTS Ten randomised controlled trials met the inclusion criteria. Six placebo-controlled studies (pharmacotherapy) and four comparative studies (one stereotactic neurosurgery and three neurorehabilitation) were reviewed. No standardised outcome measures were used across the studies. In general, pharmacotherapies were unrewarding and data on neurosurgery or rehabilitation is insufficient to lead to a change in practice. AUTHORS' CONCLUSIONS The absolute and comparative efficacy and tolerability of pharmacotherapies to treat ataxia in MS are poorly documented and no recommendations can be made to guide prescribing. Although studies on neurosurgery and neurorehabilitation showed promising results, the absolute indications for treating with those methods cannot be developed. Standardised, well validated measures of ataxia and tremor need to be developed and employed in larger randomised controlled trials with careful blinding.

Abstract
To evaluate the therapies for cerebellar diseases appropriate neurological assessment methods to measure severity of ataxia are required. Reliability and validity of the semiquantitative International Cooperative Ataxia Rating Scale (ICARS) has recently been examined in patients with degenerative ataxias. We evaluated reliability (internal consistency), criterion-related validity and internal construct validity of ICARS for the first time in patients with focal cerebellar lesions (68 patients with surgical lesions and 68 patients with ischemic lesions). For comparison 45 patients with degenerative cerebellar ataxia were included. We found an excellent Cronbach's alpha as a measurement for internal consistency which was independent from underlying disease. Criterion-related validity was high. Total ICARS score mirrored clearly the immediate postsurgical worsening and the improvement during the first 3 months after focal surgical and ischemic lesions, whereas in chronic state of focal and degenerative cerebellar disorders ICARS score remained nearly unchanged. Principal component analysis in patients with focal lesions revealed five distinct and clinically meaningful factors which corresponded to the four ICARS subscores and reflected the laterality of kinetic functions. In degenerative disorders, however, the items for the subscore "kinetic function" loaded to more than one factor. Total ICARS score seems to be a useful and valid measurement to describe the time course of ataxia in patients with focal and degenerative disorders affecting primarily the cerebellum. Validity of subscores however is good in focal, but not in degenerative disorders.

Abstract
BACKGROUND There is little information about the need for orthopaedic surgery in adults with cerebral palsy; we wanted to assess this problem. MATERIAL AND METHODS The material included 37 adults with cerebral palsy (19 women and 18 men), mean age 39. The degree of physical disability was mild in 19 cases, moderate or severe in 18. The patients were assessed by clinical examination and radiographs of hips and spine. RESULTS 15 patients had pain located to the spine or lower extremities but no-one had severe or invalidating pain. Subjects with moderate or severe disability had a markedly reduced range of motion in the hip and knee joints. Subluxation or dislocation of the hip joints was found in six patients but only one of them had hip pain. Orthopaedic surgery had been performed in 23 patients. In 8 patients we found indications for additional orthopaedic surgery aimed at relieving pain, reducing contractures or improving function. The most frequent procedures would be tenotomies in the hip and knee regions, heel cord lengthening, and triple arthrodesis of the foot. INTERPRETATION Regular follow-up of adults with cerebral palsy is recommended in order to reveal musculoskeletal problems that can be improved by orthopaedic surgery.

Abstract
INTRODUCTION Mutism after posterior fossa tumour resection is generally said to be transient. Our experience suggested that speech did not usually normalise, and that mutism was associated with neurologic deficits that did not recover fully. METHODS Children with mutism after posterior fossa tumour resection, and alive more than 2 years post-operatively, were reviewed retrospectively. Charts were reviewed and parents contacted to ascertain details about mutism, associated neurologic deficits, and the most recent speech and neurologic status. RESULTS There were 7 children, with follow-up ranging from 2.5 to 13.1 years (mean 6.8 years). Tumours were midline, with 4 astrocytomas and 3 medulloblastomas. Mutism was noted immediately after post-operative extubation in all patients. Speech reappeared 1-15 weeks post-operatively, except for 1 patient, who remained mute at 2.5 years. Speech returned to normal in only 1 patient. Mutism was always accompanied by new or worsened cerebellar ataxia, which resolved incompletely in the long term. Sixth nerve palsies occurred in 3 and recovered incompletely. Seventh nerve paresis occurred in 2 and recovered completely. CONCLUSION Mutism after posterior fossa tumour resection is associated with other neurologic deficits, particularly ataxia. Whereas speech usually returns, contrary to general opinion, speech rarely normalises. Other associated deficits rarely resolve completely. These findings have significant implications for counselling of family and patients.

Abstract
OBJECTIVE To assess the long-term effectiveness of the UroLume trade mark wallstent (Pfizer Inc., UK) in the treatment of detrusor external sphincter dyssynergia (DESD) in quadriplegic patients. PATIENTS AND METHODS Twelve patients with quadriplegia secondary to spinal trauma underwent external striated sphincter stenting with the UroLume wallstent instead of an external sphincterotomy for DESD (mean age 41.8 years, range 26-65). The level of injury was C4 in two, C5 in four, C6 in four, C7 in one and T6 in one. All patients were shown by preoperative video-cystometrography (VCMG) to have DESD and high-pressure, hyper-reflexic bladders with incomplete emptying. RESULTS Seven of the 12 patients had a mean (range) follow-up of 12.7 (12.17-13.6) years; two others were lost to follow-up at 1 and 3 years and both remained free of complications during that time. Two patients developed encrustation causing obstruction, requiring stent removal within a year of insertion. Another patient with an adequately functioning stent died 7 years after surgery (chest infection). Urodynamic follow-up of the seven patients showed a significantly sustained reduction in maximum detrusor pressure and duration of detrusor contraction at> 10 years of follow-up. Five of the seven patients developed bladder neck dyssynergia of varying degrees, as shown on VCMG; all were successfully treated with bladder neck incision. There were no problems with stent migration, urethral erosion, erectile dysfunction or autonomic dysreflexia. CONCLUSION Permanent urethral stenting using the UroLume wallstent is effective in managing DESD and provides an acceptable long-term alternative to sphincterotomy. Subsequent bladder neck dyssynergia is the main complication but this can be managed successfully with bladder neck incision. Importantly, unlike sphincterotomy, there is no significant interference with erectile function. Also, the procedure is reversible, minimally invasive and requires a shorter hospital stay.

Abstract
Holmes' (rubral or midbrain) tremor is an unusual combination of 2 Hz to 5 Hz rest, postural, and kinetic tremors of an upper extremity. This tremor has been considered to result from the lesions in the vicinity of the red nucleus in the midbrain. There has been no systematic analysis of the surgical target in the Holmes' tremor so far of nucleus ventrointermedius (Vim) or globus pallidus interna. This 26 year old man gradually developed a disabling midbrain tremor involving both the distal and proximal parts of the left upper arm. Additional neurological findings included oculomotor palsy and ataxia of the left arm. On the radiological studies, a mass lesion (germinoma) was found on the midbrain tegmentum, which was treated by conventional radiation therapy. Although there was improvement in the radiological imaging, his midbrain tremor became intolerable despite medical treatment. The authors performed MR guided stereotactic Vim thalamotomy. With radiofrequency lesioning in the right Vim, his resting, postural, and action tremors were much alleviated in both the distal and proximal parts of the left upper extremity. The authors consider that Vim thalamotomy is still an effective means of controlling midbrain tremors involving the proximal upper limb.

Abstract
Embryonic cerebellar, neocortical, and striatal tissues derived from NSE-LacZ transgenic mice were transplanted into the right cerebellar hemisphere of 8- to 10-day-old Lurcher or wild-type mice. Host mice survived for 30-90 days and the transplanted tissue was examined by light microscopy using Nissl staining, X-gal histochemistry, and immunohistochemistry for calcium binding protein and glutamic acid decarboxylase. Transplantation of cerebellar tissue, but not neocortical or striatal progenitors, resulted in robust infiltration of the lurcher mutant host cerebellar cortex by transgenic Purkinje neurons. Deep to the infiltrated molecular layer, the host granular layer was thicker and denser than the mutant granular layer, but transgenic cells did not contribute to the spared granular layer. The host inferior olivary complex consistently exhibited a noticeable bilateral asymmetry in Nissl-stained sections. A quantitative analysis of the olivary complex was performed in 10 90-day-old host mice. The results indicate that the left inferior olivary complex of 90-day-old host mice contained more neurons than the right inferior olive of the host mice and contained more neurons than was observed in 90-day-old Lurcher control mice. Analysis by olivary subdivision indicates that increased neuron numbers were present in all subdivisions of the host left inferior olive. These studies confirm the specific attractive effect of the mutant cerebellar cortex on transplanted Purkinje neuron progenitors and indicate that neural transplants may survive the neurodegenerative period to interact with developing host neural systems. The unilateral rescue of Lurcher inferior olivary neurons in cerebellar transplant hosts indicates that transplanted neurons may interact with diseased host neural circuits to reduce transneuronal degeneration in the course of a neurodegenerative disease.

Abstract
Galactocerebrosidase-deficient oligodendrocytes of 'twitcher' (twi/twi) mice degenerate prematurely. Transplantation of normal bone marrow cells has been shown to alleviate symptoms and to prolong survival time. However, characteristic ataxia ('twitching') is not cured. In an attempt to improve further the condition of twitcher mice, allogeneic foetal liver cells were transplanted as a source of normal haemopoietic stem cells and supplemented with intracerebral transplantation of foetal brain cells. A reliable method was developed to detect donor-type cells in brain tissue. Bacteriophage lambda transgenic foetal mice were used as donors of both foetal liver and brain cells. Integrated copies of lambda DNA in donor cells were detected by in situ hybridization with biotinylated probes, which were then stained using streptavidin alkaline phosphatase. This technique was combined with immunohistochemistry to distinguish donor-type oligodendrocytes from macrophages. Immunoperoxidase staining with an antiserum to carbonic anhydrase-II produced dark perikarya of oligodendrocytes. The results demonstrated that local foetal brain cell grafts resulted in a wide dissemination of donor-type oligodendrocytes throughout the twitcher brain. The addition of a foetal brain cell graft to haemopoietic cell transplantation resulted in significantly prolonged survival of twitcher mice.

Abstract
A one-stage total repair was successfully accomplished in a Japanese girl, 7 years, 8 months old, who had asplenia syndrome with vixceral heterotaxia, isolated levocardia, and complicated cardiovascular anomalies; double-outlet right ventricle with d-malposition of the great arteries (anterior aorta, posterior pulmonary trunk), complete form of endocardial cushion defect, total anomalous pulmonary venous drainage, pulmonary stenosis, sinus venosus type of atrial septal defect, patent ductus arteriosus, bilateral superior venae cavae, and inferior vena cava draining into the left-sided atrium. A routine cardiopulmonary bypass, consisting of ligations of the patent ductus arteriosus and right superior vena cava, was followed by direct and patch closure of atrial and ventricular septal defects. An internal conduit was inserted to drain the systemic venous blood from the left ventricle to the pulmonary artery. Thus a total repair is physiologically possible in such complicated cardiovascular anomalies with an asplenia syndrome. One year after this operation the child is well and attends school daily.

Abstract
Stereotaxic subthalamotomy of 55 patients with cerebral palsy gave a good result in 65% of the selected cases. The result was uncertain in 15 and poor in 20%. An independent socio-medical follow-up study confirmed the clinical finding. The more rapid the involuntary movements, the better was the effect of subthalamotomy. Intention tremor was the most suitable symptom for stereotaxic treatment. Rigidospasticity was alleviated in the distal muscles only. Speech and gait were often improved. Good results were obtained in patients with normal intelligence, while feeble-minded patients did not benefit from the operation. Subthalamotomy was followed by transitory side-effects in 20%, of which increased involuntary movements on the ipsilateral side and mental restlessness were the most frequent. The operation had no mortality. Spinal longitudinal myelotomy effectively relieved the spasticity of the lower limbs in the three patients operated upon.
