Object. Whether decompressive hemicraniectomy is an appropriate treatment for space-occupying middle cerebral artery (MCA) infarction is still a controversial issue. Previous studies are in agreement on a reduction of the mortality rate, but the reported functional outcome was highly variable. The authors sought to determine functional impairment, disability, and health-related quality of life (QOL) outcome in long-term survivors who had undergone this procedure, and tried to identify factors related to functional outcome. Methods. The study included 36 consecutive patients (mean age 58.8 ± 12.7 years, 20 men and 16 women) who underwent decompressive hemicraniectomy for treatment of malignant MCA infarction (29 on the right and seven on the left side; mean time to surgery 37.8 ± 20 hours). The survival rate was determined at 6 months: 13.7 ± 6.7 months after the stroke, a cross-sectional personal investigation of survivors was performed to assess functional impairment, disability, and health-related QOL. Survival rates were 78% at 6 months and 64% at the time of the follow-up investigation; one patient was lost to follow up. Sixteen of 22 long-term survivors lived at home. The median Barthel Index (BI) was 45 (25th and 75th percentile 19 and 71) and the BI correlated negatively with patient age (r = −0.58, p = 0.005). Three patients reached a BI of at least 90. Older age, more severe neurological deficit on admission, and longer duration of intensive care treatment and mechanical ventilation were significantly associated with worse disability (BI < 50). The health-related QOL was considerably impaired in the subscales of mobility, household management, and body care. Conclusions. Decompressive hemicraniectomy improves survival in patients with malignant MCA infarction when compared with earlier reports of conservative treatment alone. Functional outcome and QOL remain markedly impaired, especially among elderly patients and in those with a severe neurological deficit at admission.

Object. Because of the rarity of spinal subdural hematomas (SDHs), the literature offers scarce estimates of the outcome and predictive factors in patients suffering from these lesions. In addition, single-institution surgical series are still lacking. Therefore, the authors retrospectively evaluated the early and long-term functional outcomes measured in eight patients with spontaneous and nonspontaneous spinal SDHs in whom the clot had been evacuated. Methods. The patients' charts were evaluated for origin of the lesion, risk factors, and neurological deficits at symptom onset and at 28 days after extirpation of the spinal SDH. Long-term clinical outcome (Barthel Index [BI]) was evaluated by administering a telephone questionnaire to the patient or a relative. Only one patient with a spontaneous spinal SDH was identified. Four patients were undergoing anticoagulant therapy, and three patients had undergone a previous anesthetic/diagnostic spinal procedure. Twenty-eight days postoperatively, neurological deficits improved in six of eight patients; however, in two of the six patients, the improvement did not allow the patients to become independent again. In two patients, surgery did not affect the complete sensorimotor deficits. In the long-term survivors (median 45 months) a median BI of 55 was achieved. The latency between symptom onset and surgery did not correlate with functional outcome in this series. The preoperative neurological condition and location of the hematoma correlated positively with early and long-term functional outcome. Conclusions. To the best of their knowledge, the present study is the largest single-institutional study of patients with surgically treated spinal SDHs. Despite some postoperative improvement of sensorimotor deficits in most patients, the prognosis is poor because 50% of the patients remain dependent. Their outcome was determined by the preoperative sensorimotor function and spinal level of the spinal SDH.

Background: Decompressive hemicraniectomy (DH) is a level IA therapy for malignant middle cerebral artery (MCA) infarction. However, randomized trials were performed in high income countries with better access to post-stroke care and rehabilitation services. We aimed to assess long term functional outcome and the associated prognostic factors of patients undergoing DH in Brazil. Methods: From January 2013 and July 2018, all patients undergoing DH for malignant MCA infarction in a single comprehensive stroke center were retrospectively identified. Outcomes were the modified Rankin Scale (mRS) (dichotomized as ≤ 4 vs. > 4) and mortality at follow-up. The mRS at follow-up was collected prospectively by telephone using a validated structured interview. Logistic regression analysis was performed to assess independent predictors of outcome. Results: Eighty patients who underwent DH for malignant MCA infarction were identified. Age ranged from 16 to 78 years (median 48 years, IQR 42 - 54,7 years), 46 (57.6%) were males and median time from stroke onset to hemicraniectomy was 30.75 hours (IQR 17.8-46.0). Hospital discharge mRS ≤ 3 and ≤ 4 was observed in 5 (6.2%) and 74 (92,5%) patients respectively. Follow-up information was available for 65 (81.2%) patients. At follow-up (raging from 1.1 to 5.6 years), mRS ≤ 4 was observed in 23 (35.3%) patients. In binary logistic regression analysis, age (OR 1.09, 95% CI 1.02 - 1.17, p=0.01), and right MCA infarction (OR 16.70, 95% CI 1.8-152.30, p=0.01) were independently associated with a worse functional outcome at follow-up. Admission NIHSS (OR 1.0 ,95% CI 0.8-1.3, p=0.45), IV rt-PA (OR 0.5, 95% CI 0.08-3.00, p=0.46) or time of hemicraniectomy (OR 1.00, 95% CI 1.00 - 1.00, p=0.94) were not associated with functional outcome at follow-up. Mortality was 26% (N=21) at hospital discharge and 46% (N=30) at follow-up. Conclusion: The large effect size of DH for malignant MCA infarction is significantly diminished in the population of patients treated under the less than ideal conditions typically found in the public healthcare system of a developing country. Poor access to post-stroke care and rehabilitation services might be possible reasons for the results observed.

Object. A canine model of hemorrhagic vasospasm of the high cervical internal carotid artery (ICA) was used to study the long-term effects of transluminal balloon angioplasty (TBA) on the structure and function of the arterial wall.Methods. Forty dogs underwent surgical exposure of both distal cervical ICAs, followed by baseline angiographic studies on Day 0. Dogs in Group A (20 animals) underwent simple exposure of one ICA and placement of a silicone elastomer cuff around a segment of the opposite artery. These animals underwent repeated angiography on Day 7, and then TBA was performed on the uncuffed ICA; the cuff was removed from the opposite vessel. For dogs in Group B (20 animals), blood clot—filled cuffs were placed around both ICAs, and on Day 7 angiography was repeated and TBA was performed on one randomly selected ICA. Four animals were then killed from each group, and in the remaining animals the cuffs were removed from both ICAs. On Days 14, 21, 28, and 56, four animals from each group underwent repeated angiography and were then killed to permit pharmacological and morphological analyses of the ICAs. This protocol yielded five study categories: cuffed nonblood-coated arteries not subjected to TBA, blood-coated arteries not subjected to TBA, blood-coated arteries subjected to TBA, normal arteries subjected to TBA, and control arteries obtained from the proximal ICA in each animal. The contractile responses of isolated arterial rings obtained from each ICA were recorded after treatment with potassium chloride, noradrenaline, and serotonin, whereas relaxations in response to the calcium ionophore A23187 and papaverine were recorded after tonic contraction to noradrenaline had been established. Morphological analysis was performed using scanning electron microscopy.Arteries surrounded by an empty cuff exhibited no angiographic, pharmacological, or morphological differences compared with normal arteries on any study day. Arteries surrounded by blood developed angiographically confirmed vasospasm on Day 7, with characteristic pharmacological and morphological features; resolution of these symptoms occurred by Day 21. Vasospastic arteries subjected to TBA on Day 7 remained dilated on angiographic studies, exhibited impaired responses to pharmacological agents (except for papaverine), and showed altered morphological features until Day 28. Normal arteries subjected to TBA on Day 7 remained dilated on angiographic studies, exhibited impaired responses to pharmacological agents (except for papaverine), and displayed altered morphological features until Day 14.Conclusions. These results indicate that the canine high cervical ICA model produces consistent and reproducible vasospasm that follows a similar time course to that seen in humans. When TBA is performed in vasospastic arteries, it results in an immediate functional impairment of vascular smooth muscle that lasts for 2 weeks, with resolution at 3 weeks; morphological changes are mostly resolved 3 weeks post-TBA. In normal vessels, TBA causes functional impairment and morphological alterations that are not as severe or as long-lasting as those seen in vasospastic arteries.

Object. Selective posterior rhizotomy (SPR) is a well-recognized treatment for children with spastic cerebral palsy (CP). Few investigators have used quantitative outcome measures to assess the surgical results beyond 3 years. The authors analyzed data obtained from the McGill Rhizotomy Database to determine the long-term functional outcome of children who had undergone selective dorsal rhizotomy accompanied by intraoperative electrophysiological monitoring. Methods. The study population was composed of children with spastic CP who underwent SPR and were evaluated by a multidisciplinary team preoperatively, and at 6 months and 1 year postoperatively. Quantitative standardized assessments of lower-limb spasticity, passive range of motion, muscle strength, and ambulatory function were obtained. Of the 93 patients who met the entry criteria for the study, 71 completed the 3-year and 50 completed the 5-year assessments, respectively. Statistical analysis demonstrated significant improvements in spasticity, range of motion, and functional muscle strength at 1 year after SPR. The preoperative, 1-, 3-, and 5-year values for the global score of the Gross Motor Function Measure were 64.6, 70.8, 80, and 85.6, respectively. The greatest improvement occurred in the dimensions reflecting lower-extremity motor function, where the mean change was 10.1% at 1 year, 19.9% at 3 years, and 34.4% at the 5-year follow-up review in comparison with the baseline value. This was associated with a lasting improvement in alignment and postural stability during developmental positions, as well as increased ability to perform difficult transitional movements. Conclusions. The results of this study support the presence of significant improvements in lower-limb functional motor outcome 1 year after SPR, and the improvements persist at 3 and 5 years. The authors conclude that SPR in conjunction with intraoperative stimulation is valuable for permanently alleviating lower-limb spasticity while augmenting motor function.

Group 1

✓ In a pilot study, two groups of patients with malignant glioma underwent sequential neuropsychological evaluations after successful tumor treatment. Group 1 included nine patients treated from 1981 to 1985; all patients received irradiation and eight underwent chemotherapy. The baseline neuropsychological assessment was performed 1 to 63 months after tumor diagnosis, with follow-up evaluations at irregular intervals over the next 3 to 7 years. Six patients in Group 1 exhibited impairment on most measures at baseline; subsequently, two patients developed profound cognitive impairment. Initially, three patients functioned in the average range on most tasks; thereafter, two deteriorated on one measure each. Group 2 was ascertained prospectively and included 16 patients treated from 1985 to 1987, all of whom received irradiation and chemotherapy. The first evaluation was performed 18 months after diagnosis, then every 6 months for 2 years, and then yearly. Compared to a control group, those in Group 2 had significant cognitive impairment at baseline. Cognitive performance did not change over the next 12 months in 10 patients who remained free of tumor, but within 2 years of baseline testing, deterioration on specific tasks was evident in two of seven disease-free survivors. When last tested, five of six disease-free survivors had deteriorated on one or more measures. Unlike Group 1, severe global cognitive impairment was not seen, perhaps because Group 2 was followed for a shorter time. Verbal and nonverbal composite scores derived from intelligence quotient (IQ) tests showed less impairment at baseline than did other measures and were more likely to remain stable subsequently. Verbal memory and sustained attention were the most impaired at baseline, and verbal learning and flexibility in thinking showed the greatest tendency to decline over time. Cognitive functioning in survivors of high-grade glioma is best measured and monitored by tests that probe a broader spectrum of abilities than IQ. Neuropsychological measures used in this analysis lacked sensitivity at the lower end of the impaired range. Future studies should use tests better able to discern cognitive differences at low performance levels. Based on this experience, the authors conclude that most long-term survivors of high-grade glioma will have significant cognitive difficulties, usually evident by the first assessment; some patients will develop profound impairment years later, and few are capable of fully independent living.

✓ The reported success of treatment for children with medulloblastoma must be balanced against the effect that treatment has on the quality of life of long-term survivors. The outcome of long-term survivors reported in previous studies has been conflicting. The authors evaluate the mental and behavioral skills of a group of medulloblastoma survivors from their institution, all of whom had survived for more than 5 years postdiagnosis. A review of the institutional records yielded 32 patients. Twenty-three families were interviewed by telephone and, of these, 13 subjects came to the hospital for detailed neuropsychological and neurological evaluations. Intelligence quotient (IQ) was less than 90 for all participants tested, and patients diagnosed before the age of 3 years had lower IQ scores on average than those diagnosed later. Mean IQ and achievement test scores in reading, spelling, and mathematics were all higher in survivors who had undergone shunting. Achievement test results were often not in accord with intellectual potential, and individual intellectual skills varied widely. Perceptual-motor task performance was below average in more than 50% of the participants, but motor dexterity was more severely affected than perception. Problems in learning and a delay in both physical growth and development were seen in a majority of participants. This study directs attention to the serious difficulties faced by long-term survivors of medulloblastoma and their families, and underscores the importance of routine neuropsychological testing. Moreover, the study provides further impetus to seek alternatives to irradiation in the treatment of malignant brain tumors.

✓ A retrospective survey of 41 patients with unbiopsied thalamic, pontine, and medullary tumors treated with radiation therapy demonstrated 30% to 40% 3-year survival, with seven long-term survivors. Eleven of the 12 patients surviving over 3 years have essentially normal neurological function. Of seven patients in whom histological diagnoses were eventually obtained, four proved to have glioblastomas and three low-grade astrocytomas. Autopsy revealed that all glioblastomatous tumors extended beyond the treatment field; this suggested that larger volumes, perhaps the whole brain, should be irradiated. High doses (at least 5000 rads) should be used since the 3-year survival among those receiving such doses was 45%.

ABSTRACT Background: The incidence of long-term survival in glioblastoma (GBM), i.e., >3 years, ranges from 3% to 5%. Although extensive research is performed in novel therapies for prolonging survival, there is a scarcity of research focusing on the impact of tumor and treatment on cognitive, psychological, and social status of survivors. This study is an attempt to look into this poorly addressed important issue. Materials and Methods: Nine patients (six adults and three children) with GBM who had survived >3 years were included in the study. The quality of life (QOL) functions were assessed with the World Health Organization QOL Questionnaire BREF questionnaire. The neuropsychological assessment was done using the National Institute of Mental Health and Neurosciences neuropsychology battery for adults and children. The scores were compared with normative data. Results: The physical and psychological health-related QOL of long-term GBM survivors were affected considerably due to fatigue, poor quality of sleep, inability to concentrate, presence of depression, financial burden with impaired personal and social relationships (P < 0.05). Different domains of cognitions such as motor speed (P = 0.0173), mental speed (P = 0.0022), sustained attention (P = 0.0001), long-term memory (P = 0.0431), mental flexibility (P < 0.05), and planning and executive functions (P < 0.05) were significantly impaired affecting personal, social, and professional lives. Conclusion: The health-related QOL and cognition are significantly impaired in GBM long-term survivors. As the incidence of long-term survival is very less, there is a need for larger multicenter studies to come up with definitive results, which in turn can help in formatting the rehabilitative and support programs for these patients.

Object. The primary goal of this study was to describe the long-term health-related quality of life (HRQOL) outcomes in patients who have suffered Jefferson-type fractures. These outcomes were compared with matched normative HRQOL data and with the patient's perceptions of their HRQOL prior to the injury. Variables that potentially influence these HRQOL outcomes were analyzed. No standardized outcome assessments have been published for patients who suffer these fractures; their outcomes have long thought to be excellent following treatment. Determining the optimal surrogate measure to represent preinjury HRQOL in trauma patients is difficult. Methods. A retrospective review, radiographic analysis, and cross-sectional outcome assessment were performed. The Short Form (SF)—36 and the American Academy of Orthopaedic Surgeons/North American Spine Society (AAOS/NASS) outcome instruments were filled out by patients at final follow-up examination (follow-up period 75 months, range 19–198 months) to represent their current status as well as their perceptions of preinjury status. In 34 patients, the SF-36 physical component score and the AAOS/NASS pain values were significantly lower than normative values. There was no significant difference between normative and preinjury values. Spence criteria greater than 7 mm and the presence of associated injuries predicted poorer outcome scores during the follow-up period. Conclusions. Long-term follow-up examination of patients with Jefferson fractures indicated that patients' status does not return to the level of their perceived preinjury health status or that of normative population controls. Those with other injuries and significant osseous displacement (≥ 7 mm total) may experience poorer long-term outcomes. Limitations of the study included a relatively low (60%) response rate and the difficulties of identifying an appropriate baseline outcome in a trauma population with which the follow-up outcomes can be compared.

Object. The study was conducted to determine the association between dual-isotope single-photon emission computerized tomography (SPECT) scanning and histopathological findings of tumor recurrence and survival in patients treated with high-dose radiotherapy for glioblastoma multiforme. Methods. Studies in which SPECT with 201Tl and 99mTc-hexamethypropyleneamine oxime (HMPAO) were used were performed 1 day before reoperation in 47 patients with glioblastoma multiforme who had previously been treated by surgery and high-dose radiotherapy. Maximum uptake of 201Tl in the lesion was expressed as a ratio to that in the contralateral scalp, and uptake of 99mTc-HMPAO was expressed as a ratio to that in the cerebellar cortex. Patients were stratified into groups based on the maximum radioisotope uptake values in their tumor beds. The significance of differences in patient gender, histological characteristics of tissue at reoperation, and SPECT uptake group with respect to 1-year survival was elucidated by using the chi-square statistic. Comparisons of patient ages and time to tumor recurrence as functions of 1-year survival were made using the t-test. Survival data at 1 year were presented according to the Kaplan—Meier method, and the significance of potential differences was evaluated using the log-rank method. The effects of different variables (tumor type, time to recurrence, and SPECT grouping) on long-term survival were evaluated using Cox proportional models that controlled for age and gender. All patients in Group I (201Tl ratio < 2 and 99mTc-HMPAO ratio < 0.5) showed radiation changes in their biopsy specimens: they had an 83.3% 1-year survival rate. Group II patients (201T1 ratio < 2 and 99mTc-HMPAO ratio of ≥ 0.5 or 201Tl ratio between 2 and 3.5 regardless of 99mTc-HMPAO ratio) had predominantly infiltrating tumor (66.6%); they had a 29.2% 1-year survival rate. Almost all of the patients in Group III (201Tl ratio > 3.5 and 99mTc-HMPAO ratio ≥ 0.5) had solid tumor (88.2%) and they had a 6.7% 1-year survival rate. Histological data were associated with 1-year survival (p < 0.01); however, SPECT grouping was more closely associated with 1-year survival (p < 0.001) and was the only variable significantly associated with long-term survival (p < 0.005). Conclusions. Dual-isotope SPECT data correlate with histopathological findings made at reoperation and with survival in patients with malignant gliomas after surgical and high-dose radiation therapy.
