RESUMO
Background: Anterior cervical discectomy and fusion (ACDF) is a commonly implemented surgical intervention for a variety of pathologies affecting the cervical spine. The current literature and daily practice reveal variations on patient head positioning for this procedure with both rigid fixations in the Mayfield skull clamp as well as use of a padded headrest being used. In this study, we therefore examine whether patients undergoing surgery using head positioning in the Mayfield skull clamp versus a padded headrest differ in regard to adverse events, surgical parameters and clinical outcome. Methods: A single-center, retrospective analysis of 121 patients treated with ACDF for degenerative disease, traumatic cervical spine injury and infectious disease between November 2019 and March 2023 was performed. Clinical and imaging data for 59 patients positioned in the Mayfield skull clamp and 62 patients positioned in a padded headrest were evaluated using electronic medical records. In addition to demographic data, surgical indications, procedures performed were analyzed for both groups. Level of training (chief, attending and resident), length of surgery and intraoperative radiation exposure (measured by dose area product and total radiation time) were also examined. Finally, modified Rankin Scale (mRS) preoperatively and at last follow-up as well as adverse events were compared between groups. Results: We found no statistically significant differences between the Mayfield and headrest groups regarding surgical indications (P=0.583), procedures performed (P=0.069), level of training of the surgeon (P=0.218), length of surgery (P=0.752), adverse events (P=0.619) or neurological impairment (P=0.080) following surgical intervention. There was a significant difference regarding dose area product between both groups with patients positioned in the Mayfield skull clamp showing lower mean levels of radiation than those in the headrest group (99 versus 131 cGy/cm2; P=0.003). Conclusions: Patient positioning using the Mayfield skull clamp may reduce required radiation exposure during ACDF procedures versus use of a padded headrest.
RESUMO
Background incidence of pyogenic spinal infections has increased in recent years. In addition to treating the spinal infection, optimal care also includes identifying the source of the pyogenic spinal infection and the presence of other infections. The aim of this study is to elucidate the prevalence of oral cavity infection (OCI) within this patient cohort. Methods As part of a prospective study conducted from 2016 to 2021, the number of patients with dental infections was investigated by means of an orthopantomogram (OPG) and subsequent dental examination. Results The presence of an oral infection was investigated in 55 (47%) of 118 patients by an OPG, 29 (53%) of whom had a corresponding abnormality of the oral cavity. In addition to the spinal infection, patients with an oral cavity infection revealed an increased incidence of endocarditis, sepsis and brain abscess. A spinal epidural abscess, a multilevel affection of the infection, and an elevated CRP value were also found in patients with a co-existing oral cavity infection. Back pain assessed at admission and 3 months after surgery was also more pronounced in patients with an oral cavity infection. Neurological deficits were often present in patients with spinal and oral cavity infection. Conclusions The presence of an oral cavity infection has proven to be one of the important factors in the detection of the source of the pyogenic spinal infection. In addition, a pronounced spinal affection and frequent co-infections were seen in patients with an oral cavity infection.
RESUMO
Objective: Outpatient parenteral antimicrobial therapy (OPAT) is a well-established and cost-effective method for improving the efficient use of healthcare resources. However, only a few centres in Germany perform it. Here we analysed OPAT for the treatment of patients with cranial infections in our neurosurgical department. Methods: This retrospective study analysed patients with cranial infections and the need for intravenous (i.v.) antimicrobial treatment between 2018 and 2021.All diagnosed intracranial infections were defined into two infection categories such as long-term antimicrobial treatment and short-term antimicrobial treatment. All included patients were discharged with a peripherally inserted central catheter (PICC) line. Prior to discharge, all patients received training in the safe administration of their medications via the PICC line. The duration of OPAT and the rate of readmission after OPAT were analysed. Results: We identified a total of 45 patients treated with OPAT for cranial infections. Intradural involvement was present in 40 cases (88.9%). The average length of hospital stay for this cohort after surgical treatment was 45 ± 15 days. 5 patients were treated for soft tissue/skin infection. Surgery was not required in this cohort. The mean hospital stay for this cohort was 8 ± 6 days. Gram-positive organisms were isolated in most cases (53.3%). The most common pathogens were Staphylococcus aureus followed by other Staphylococcus species. For all included patients, OPAT was performed after discharge for an average of 43.1 ± 14 days. There were five cases of readmission due to treatment failure. No serious adverse events or complications of OPAT were observed. Conclusion: OPAT enables better patient-centred healthcare close to home. The length of hospital stay can be reduced and adverse events due to prolonged hospitalisation can be avoided.
RESUMO
Spinal tuberculosis is due to globalization no longer a disease limited to developing nations. It remains in Germany a rarity and still a difficult diagnosis. Here we analyzed patients with spinal tuberculosis treated at our neurosurgical department. According to the infected anatomic segment, patients were assigned in one of three groups. Surgery was performed when neurological deficit due to mechanical compression, deformity, instability, severe pain, necrotic bone or failure to respond to anti-tuberculous treatment were observed. We identified 34 patients with spinal tuberculosis who underwent surgical treatment. In the cervical spinal tuberculosis group, there were 15 cases (46.9%) In most cases treatment consisted of spinal instrumentation. In the thoracic group, 10 cases (29.4%) were observed. The treatment was performed by dorsolateral spinal instrumentation. For the thoracolumbar group, 9 cases (26.4%) were observed. In most cases dorsolateral spinal instrumentation was performed. One patient in the first group and one patient in the third group relapsed after operation. A second surgery was necessary. Patients with chronic back pain, immigration background and/or neurological deficit spinal TB should be considered as a differential diagnosis. Combined surgical intervention and medical treatment is associated with a favorable outcome.

OBJECTIVE: While outcomes of surgical treatment for spinal meningiomas are well-described within the literature, factors affecting early return to work as well as long-term health related quality of life remain unclear. METHODS: In this retrospective study, patients with spinal meningioma and surgical treatment from two university-level neurosurgical institutions between 2008 and 2021 were analyzed. Time to return to work, physical activities and long-term health related quality of life (assessed by telephone interviews using the EQ-5D-5L health status measure and visual analogue scale (EQ VAS) were analyzed. RESULTS: We identified a total of 196 patients who underwent microsurgical resection of spinal meningioma between January 2008 and December 2021. Of those, 130 patients of working age were included and analyzed. The median follow-up time was 96 months. All included patients returned to work. The median time of return to work was 45 days for the whole cohort. Patients who preoperatively performed physical activity returned to work significantly earlier compared to patients who did not (p < 0.001). Furthermore, younger age (p = 0.033) and absence of obesity (p = 0.023) correlated significantly with earlier return to work. Significant differences were also observed in all 5 EQ-5D-5L dimensions between patients with and without preoperative physical activity. CONCLUSIONS: Despite the benign nature of spinal meningioma preoperative physical activity and physiological body weight are associated with favorable postoperative outcome, higher quality of life and early return to work.
RESUMO
Outpatient parenteral antimicrobial therapy (OPAT) is a cost-effective method of administering intravenous antimicrobial therapy. Although OPAT is well established in the UK and US healthcare systems, few centres in Europe perform it. Here we analysed OPAT for the treatment of patients with spinal infections at our institution. In this retrospective study, patients with spinal infection who required intravenous (i.v.) antimicrobial treatment between 2018 and 2021 were analysed. The duration of short-term antimicrobial treatment for skin and soft tissue infections and complex infections requiring long-term antimicrobial treatment, such as spinal bone or joint infections, were analysed. All patients were discharged with a peripherally inserted central catheter (PICC) line. Prior to discharge, all patients received training in the safe administration of their medications via the PICC line. The duration of OPAT and the rate of readmission after OPAT were analysed. For this study a total of 52 patients who were treated via OPAT due to spinal infections were analyzed. In 35 cases (69.2%) complex spinal infection was reason for i.v. antimicrobial therapy. Surgery was required in 23 of these 35 patients (65.7%). The average hospital stay for these patients was 12 ± 6 days. The remaining 17 patients were treated for an infection of the soft tissue or the skin and hospital stay for these patients was on average 8 ± 4 days. Gram-positive organisms were isolated in 64.4%. Staphylococcus aureus followed by other Staphylococcus species, was the most common detected organism. After discharging i.v. antimicrobial treatment was given for an average of 20 ± 14 days. The duration of antimicrobial treatment for soft tissue was 10.8 ± 8 days, and for complex infections 25.1 ± 18 days. The mean follow-up was 21 ± 14 months. There was one case of readmission due to treatment failure. There were no difficulties encountered in implementing OPAT. OPAT is a feasible and effective option for delivering intravenous antimicrobial therapy to patients with spinal infections who can be managed without hospitalisation. OPAT offers patient-centred treatment at home while avoiding the risks associated with hospitalisation, with high levels of patient satisfaction.

OBJECT: The management and recommendations for treatment strategies of pyogenic spinal infection are still a highly controversial issue. The purpose of this study was to evaluate patient's quality of life (QoL) after surgical and conservative treatment of spinal infection. MATERIALS AND METHODS: We conducted a retrospective, single-center study. All patients treated between 2009 and 2016 were included in this study. For evaluation of QoL, we recorded each patient's satisfaction according to the 36-Item Short Form Health Survey (SF-36) questionnaire. Scores were compared with a U.S. standard population. RESULTS: Two hundred and ten adult patients with spondylodiskitis were identified. Of these, 155 (74%) underwent surgery and 55 (26%) were treated conservatively. The mean overall age was 68.6 (23-98) years. Seventy-two patients were females and 138 patients were males. The mean outcome values in the surgical group did not reach the level of the normative sample in one of eight items, whereas the conservative group revealed a reduced QoL in all items. Intergroup comparison revealed significant differences in all items (p < 0.05). CONCLUSION: In the patient population we investigated, QoL in surgically treated patients was better than that in conservatively managed patients.

STUDY DESIGN: Single-center series. OBJECTIVE: Intraspinal facet joint cysts can lead to nerve root compression symptoms with severe discomfort and disability. Permanent improvement can be achieved by surgical resection of the cyst. However, cerebrospinal fluid (CSF) leakage is a common problem in resection of facet joint cyst.The aim of the study was to investigate the frequency of CSF leak after resection of a joint cyst and to determine predictive factors. METHODS: A total of 176 consecutive patients underwent surgery for lumbar spinal facet joint cyst in our institution between 1997 and 2018. Patients with a CSF leak were compared with patients without a CSF leak (control group). RESULTS: CSF leakage occurred in 14 patients (8.0%) In 2 of the cases (14.3%), the CSF leak was recognized only postoperatively, in 12 cases (85.7%), the CSF leak was detected intraoperatively. Despite intraoperative dura repair, 4 of these 12 patients (33.3%) presented with CSF leakage postoperatively. Altogether 6 patients had postoperative CSF leakage. Compared with patients without CSF leak, there were no differences in preoperative symptoms, surgical technique, complications, or postoperative findings. Adhesion of the cyst to the dura mater was present in all 14 patients with CSF leakage (100%), but only 61.7% of the control group ( P <0.005). All patients in the CSF leak group showed an improvement of their preoperative symptoms. CONCLUSIONS: The rate of CSF leakage in resection of spinal facet joint cyst was 8% in the present study. The occurrence of a CSF leakage was independent of clinical factors, level, or side of the cyst, but significantly correlated to dural adhesion of the cyst.Since neither clinical recovery nor recurrence rates do depend on complete removal of the cyst, aggressive resection of dural adherend parts of the cyst wall should be avoided to prevent CSF leakage.

Background: The incidence of pyogenic spinal infection has increased in recent years. In addition to treatment of the spinal infection, early diagnosis and therapy of coexisting infections, especially of secondary brain infection, are important. The aim of this study is to elucidate the added value of routine cerebral imaging in the management of these patients. Methods: This was a retrospective single-center study. Cerebral imaging consisting of cerebral magnetic resonance imaging (cMRI) was performed to detect brain infection in patients with a primary pyogenic spinal infection. Results: We analyzed a cohort of 61 patients undergoing cerebral imaging after diagnosis of primary pyogenic spinal infection. The mean age in this cohort was 68.7 years and the gender distribution consisted of 44 males and 17 females. Spinal epidural abscess was proven in 32 (52.4%) patients. Overall positive blood culture was obtained in 29 (47.5%) patients, infective endocarditis was detected in 23 (37.7%) patients and septic condition at admission was present in 12 (19.7%) Patients. Coexisting brain infection was detected in 2 (3.3%) patients. Both patients revealed clinical signs of severe sepsis, reduced level of consciousness (GCS score 3), were intubated, and died due to multi-organ failure. Conclusions: Brain infection in patients with spinal infection is very rare. Of 61 patients with pyogenic spinal infection, two patients had signs of cerebral infection shown by imaging, both of whom were in a coma (GCS 3), and sepsis.
RESUMO
OBJECTIVE: The aim of this study was to evaluate functional outcome, surgical morbidity, and factors that affect outcomes of surgically treated patients. METHODS: The authors retrospectively analyzed patients who underwent microsurgical resection for spinal meningiomas between 2009 and 2020. Patient data and potential variables were collected and evaluated consecutively. Functional outcomes were evaluated using univariate and multivariate analyses. RESULTS: A total of 119 patients underwent microsurgical resection of spinal meningioma within the study period. After a mean follow-up of 25.4 ± 37.1 months, the rates of overall complication, tumor recurrence, and poor functional outcome were 9.2%, 7.6%, and 5%, respectively. Age, sex, revision surgery, and tumor recurrence were identified as independent predictors of poor functional outcome. Obesity and surgeon's experience had an impact on the complication rate, whereas extent of resection and tumor calcification affected the rate of tumor recurrence. CONCLUSIONS: Microsurgical resection of spinal meningiomas remains safe. Nevertheless, some aspects, such as obesity and experience of the surgeons that result in a higher complication rate and ultimately affect clinical outcome, should be considered when performing surgery.

OBJECTIVE: Spinal epidural abscess (SEA) is a severe and life-threatening disease. Although commonly performed, the effect of timing in surgical treatment on patient outcome is still unclear. With this study, we aim to provide evidence for early surgical treatment in patients with SEA. METHODS: Patients treated for SEA in the authors' department between 2007 and 2016 were included for analysis and retrospectively analyzed for basic clinical parameters and outcome. Pre- and postoperative neurological status were assessed using the American Spinal Injury Association Impairment Scale (AIS). The self-reported quality of life (QOL) based on the Short-Form Health Survey 36 (SF-36) was assessed prospectively. Surgery was defined as "early", when performed within 12 hours after admission and "late" when performed thereafter. Conservative therapy was preferred and recommend in patients without neurological deficits and in patients denying surgical intervention. RESULTS: One hundred and twenty-three patients were included in this study. Forty-nine patients (39.8%) underwent early, 47 patients (38.2%) delayed surgery and 27 (21.9%) conservative therapy. No significant differences were observed regarding mean age, sex, diabetes, prior history of spinal infection, and bony destruction. Patients undergoing early surgery revealed a significant better clinical outcome before discharge than patients undergoing late surgery (p=0.001) and conservative therapy. QOL based on SF-36 were significantly better in the early surgery cohort in two of four physical items (physical functioning and bodily pain) and in one of four psychological items (role limitation) after a mean follow-up period of 58 months. Readmission to the hospital and failure of conservative therapy were observed more often in patients undergoing conservative therapy. CONCLUSION: Our data on both clinical outcome and QOL provide evidence for early surgery within 12 hours after admission in patients with SEA.

OBJECTIVEThe incidence of patients with pyogenic spinal infection is increasing. In addition to treatment of the spinal infection, early diagnosis of and therapy for coexisting infections, especially infective endocarditis (IE), is an important issue. The aim of this study was to evaluate the proportion of coexisting IE and the value of routine transesophageal echocardiography (TEE) in the management of these patients.METHODSThe medical history, laboratory data, radiographic findings, treatment modalities, and results of TEE of patients admitted between 2007 and 2017 were analyzed.RESULTSDuring the abovementioned period, 110 of 255 total patients underwent TEE for detection of IE. The detection rate of IE between those patients undergoing and not undergoing TEE was 33% and 3%, respectively (p < 0.0001). Thirty-six percent of patients with IE needed cardiac surgical intervention because of severe valve destruction. Chronic renal failure, heart failure, septic condition at admission, and preexisting heart condition were significantly associated with coexisting IE. The mortality rate in patients with IE was significantly higher than in patients without IE (22% vs 3%, p = 0.002).CONCLUSIONSTEE should be performed routinely in all patients with spondylodiscitis.

BACKGROUND: With the aging of our society comes a rising number of elderly patients with progressive degeneration of the spine associated with synovial cysts. Surgical treatment may be particularly challenging in elderly patients because of comorbidities. METHODS: Patients treated in our department between 1999 and 2014 for spinal synovial cysts were screened. The 28 patients ≥75 years old were classified as elderly and were compared with 96 patients 50-74 years old. No patient underwent fusion as part of cyst resection. RESULTS: Despite a significantly higher frequency of muscle reflex changes in elderly patients at presentation, symptoms, cyst levels, rate of complications, and surgical method were not different between groups. Cyst adherence to the dura and subtotal resection were observed significantly more often in the elderly group (18% vs. 3%; P < 0.05). Outcome according to the Oswestry Disability Index was classified as no disability or minimal disability in 85% of the elderly group and in 82% of the control group. Recurrent cyst and delayed fusion rates were lower in the elderly group (4% and 4%) compared with the control group (7% and 8%). CONCLUSIONS: The clinical course of elderly patients with surgical treatment of spinal synovial cysts did not differ compared with younger patients. Good or excellent results could be achieved and persisted for a long time in most cases. Fusion should be performed only in cases of severe instability. Nonaggressive cyst removal in cases of dural attachment enables low cerebrospinal fluid fistula rates without increasing cyst recurrence rates.

BACKGROUND: Proton magnetic resonance imaging (MRS) is used increasingly to image the spinal cord in compressive cervical myelopathy (CSM). However, detailed analyses of the underlying histomorphological changes leading to MRS alterations are still lacking. The aim of our study was to correlate neuroimaging and neuropathologic alterations in a rabbit myelopathy model. METHODS: Chronic spinal cord compression was induced in a rabbit model (n=16) allowing for a gradual 270° compression of the spinal cord. Spinal cord compression core areas were divided into two samples for (A) 1H MRS and (B) histopathological analyses. Postoperatively the animals underwent a neurological examination twice a day and outcome was categorized in pattern of injury and amount of recovery. RESULTS: Three groups were observed and categorized: (I) animals with severe deficits and no or minimal recovery; (II) animals with severe deficits and complete or almost complete recovery; (III) animals with mild to moderate deficits and a complete recovery. Significant differences in the lesioned spinal cords between the different recovery groups were found for N-acetyl-aspartate and choline. NAA/Cr was detected significantly (P<0.001, ANOVA) less in the group that did show permanent neurological deficits. To the contrary, choline was detected significantly (P<0.001, ANOVA) more in the group that did show permanent neurological deficits. Histologically the first group showed more apoptosis and necrosis than the second and third group. CONCLUSIONS: MR spectroscopy (MRS) may be helpful for clinicians in improving the prognostic accuracy in cervical myelopathies since this method nicely reflects the extent and severity of spinal cord damage.
RESUMO
OBJECTIVE Synovial cysts of the spine are rare lesions, predominantly arising in the lumbar region. Despite their generally benign behavior, they can cause severe symptoms due to compression of neural structures in the spinal canal. Treatment strategies are still a matter of discussion. The authors performed a single-center survey and literature search focusing on long-term results after minimally invasive surgery. METHODS A total of 141 consecutive patients treated for synovial cysts of the lumbar spine between 1997 and 2014 in the authors' department were analyzed. Medical reports with regard to signs and symptoms, operative findings, complications, and short-term outcome were reviewed. Assessment of long-term outcome was performed with a standardized telephone questionnaire based on the Oswestry Disability Index (ODI). Furthermore, patients were questioned about persisting pain, symptoms, and further operative procedures, if any. Subjective satisfaction was classified as excellent, good, fair, or poor based on the Macnab classification. RESULTS The approach most often used for synovial cyst treatment was partial hemilaminectomy in 70%; hemilaminectomy was necessary in 27%. At short-term follow-up, the presence of severe and moderate leg pain had decreased from 93% to 5%. The presence of low-back pain decreased from 90% to 5%. Rates of motor and sensory deficits were reduced from 40% to 14% and from 45% to 6%, respectively. The follow-up rate was 58%, and the mean follow-up period was 9.3 years. Both leg pain and low-back pain were still absent in 78%. Outcome based on the Macnab classification was excellent in 80%, good in 14%, fair in 1%, and poor in 5%. According to the ODI, 78% of patients had no or only minimal disability, 16% had moderate disability, and 6% had severe disability at the time of follow-up. In this cohort, 7% needed surgery due to cyst recurrence, and 9% required a delayed stabilization procedure after the initial operation. CONCLUSIONS Surgical treatment with resection of the cyst provides favorable results in outcome. Excellent or good outcome persisting for a long-term follow-up period can be achieved in the vast majority of cases. Complication rates are low despite an increased risk of dural injury. With facet-sparing techniques, the stability of the segment can be preserved, and resection of spinal synovial cysts does not necessarily require segmental fusion.

Surgical resection of intramedullary spinal cord ependymoma still remains the standard of care but is challenging and occasionally associated with poor outcome. The aim of this study is therefore to provide additional information regarding the natural history of conservatively treated symptomatic intramedullary spinal cord ependymoma. Retrospective, single center review of all patients with intramedullary spinal cord ependymoma treated conservatively (wait and see) between 1980 and 2016. The neurological outcomes at first presentation, as well as in long-term follow-up, were assessed using the modified McCormick Disability Scale and modified Rankin Scale. Thirteen of 41 patients were managed conservatively and were included in the study. Mean age at the admission was 49 years. There were seven women and six men. All patients were symptomatic at the time of presentation. The mean follow-up from admission to the last neurological examination was 47.9 months. The mean modified McCormick score in conservatively treated patients was 1.3 at admission and 1.6 (p = 0.3) at last follow-up. There was no significant neurological detoriation over time in conservatively managed patients as assessed by the modified Rankin Scale at first presentation and last follow-up (mRS scores of 0-2, 100 vs 92%; p = 0.9). This cohort of conservatively managed patients with symptomatic intramedullary spinal cord ependymoma was clinically stable throughout the follow-up period. Our data provide additional information for counseling patients with intramedullary spinal cord tumors who chose a nonoperative treatment.

BACKGROUND: Stereotactic biopsy of brain lesions with unknown entities is a common neurosurgical procedure to obtain tumor tissue. Pathologists can then provide an exact diagnosis on which further therapy, such as resection, radiotherapy, or chemotherapy, can be based. These procedures can be performed under local or general anesthesia. In this prospective study, we aim to show whether stress levels are higher for patients who undergo stereotactic biopsy under local or general anesthesia. METHODS: Between January 2013 and December 2014, we screened 157 patients. Of these, 43 were included and evaluated in this study. Twenty-one patients gave their written consent and were randomized for either local or general anesthesia. A Post Traumatic Stress Score (PTSS) questionnaire was filled out by the patients preoperatively and postoperatively. Also, patients who did not agree to randomization had an opportunity to fill out the PTSS questionnaire. Twenty-two patients agreed only to fill out the stress-level questionnaire but refused randomization. These patients were evaluated as a subgroup. Scores achieved in the PTSS were compared by using the Fisher exact test. RESULTS: Among the randomized patients, 9 underwent the procedure under local anesthesia and 12 under general anesthesia. Median PTSS was 24 preoperatively in the patients who received local anesthesia versus 20 among the patients with general anesthesia (P = 0.37; Fisher exact test). Postoperatively, PTSS was 29.5 in median for patients with local anesthesia versus 23 for patients with general anesthesia (P = 0.30; Fisher exact test). Postoperatively, the PTSS showed a median increase of 5.5 points in the LA and 3 points in the GA group (P = 0.87; Fisher exact test). P values of 0.05 and lower were considered statistically significant. CONCLUSIONS: The willingness of patients to undergo randomization in this setting was low (13.3%). Within this highly selective group of patients, there was no significant difference for stress levels in patients who underwent stereotactic biopsy under local anesthesia versus general anesthesia. However, median values indicate a trend for higher stress-level values for patients undergoing local anesthesia.

BACKGROUND: Primary intramedullary spinal cord glioblastomas are very rare tumors of the spinal cord. They imply a very poor prognosis because complete surgical resection is not possible as the result of the infiltrative growth of these tumors. The aim of this study is to present our data achieved with an aggressive multimodality treatment. METHODS: We retrospectively reviewed our clinical database. All patients with histologically proven intramedullary spinal cord glioblastoma treated in our department were included in this study. RESULTS: Four patients with intramedullary spinal cord glioblastoma were identified between 2006 and 2015, all of whom were female. Mean age at the time of surgery was 33.5 years (range 14-50 years). Tumors were located in the cervical region in 2 patients and in the thoracic region in 2 patients. All 4 patients underwent microsurgical biopsy of the tumor. After surgery, all patients received radiation and temozolomide treatment. One patient underwent additional therapy with Bevacizumab, another patient received Rapamycin and Sunitinib, and the third patient received Chlorethyl-cyclohexyl-nitroso-urea and Etoposide as additional therapy after tumor regrowth. Tumor progression occurred in a mean time of 18.2 months (6-32 months). In this series, all patients died as the result of progression of the malignancy; median survival after diagnosis was 32.5 months. CONCLUSIONS: The surgical outcome of intramedullary spinal cord glioblastoma still remains poor. Severe disability and amelioration of the neurologic status lead to reduced quality of life; however, an aggressive multimodal and interdisciplinary treatment for the disease may be associated with longer survival.

Monitoring of intracranial pressure (ICP) may be indicated in children with traumatic brain injury, premature intraventricular hemorrhage, or hydrocephalus. The standard technique is either a direct measurement with invasive intracranial insertion of ICP probes or indirect noninvasive assessment using transfontanelle ultrasonography to measure blood flow. The authors have developed a new technique that allows noninvasive epicutaneous transfontanelle ICP measurement with standard ICP probes. They compared the ICP measurements obtained using the same type of standard probe used in 2 different ways in 5 infants (age < 1 year) undergoing surgery for craniosynostosis. The first ICP probe was implanted epidurally (providing control measurements) and the second probe was fixed epicutaneously on the skin over the reopened frontal fontanelle. ICP values were measured hourly for the first 24 hours after surgery and the values obtained with the 2 methods were compared using Bland-Altman 2-methods analysis. A total of 110 pairs of measurements were assessed. There was no significant difference between the ICPs measured using the epicutaneous transfontanelle method (mean 13.10 mm Hg, SEM 6.68 mm Hg) and the epidural measurements (mean 12.46 mm Hg, SEM 6.45 mm Hg; p = 0.4643). The results of this analysis indicate that epicutaneous transfontanelle measurement of ICP is a reliable method that allows noninvasive ICP monitoring in children under the age of 1 year. Such noninvasive ICP monitoring could be implemented in the therapy of children with traumatic brain injury or intraventricular hemorrhage or for screening children with elevated ICP without invasive intracranial implantation of ICP probes.
