Abstract
INTRODUCTION To examine how bimodal stimulation affects quality of life (QOL) during the post operative period following cochlear implantation (CI). This data could potentially provide evidence to encourage more bimodal candidates to continue hearing aid (HA) use after CI. METHODS In this prospective study, patients completed preoperative, and 1-, 3- and 6-months post-activation QOL surveys on listening effort, speech perception, sound quality/localization, and hearing handicap. 15 HA users who were candidates for contralateral CI completed the study (mean age 65.6 years). RESULTS Patients used both devices a median rate of 97%, 97% and 98% of the time at 1, 3, and 6 months respectively. On average, patients' hearing handicap score decreased by 16% at 1 month, 36% at 3 months, and 30% at 6 months. Patients' listening effort scores decreased by a mean of 10.8% at 1 month, 12.6% at 3 months and 18.7% at 6 months. Localization improved by 24.3% at 1 month and remained steady. There was no significant improvement in sound quality scores. CONCLUSION Bimodal listeners should expect QOL to improve, and listening effort and localization is generally optimized using CI and HA compared to CI alone. Some scores improved at earlier time points than others, suggesting bimodal auditory skills may develop at different rates.

Abstract
OBJECTIVE To investigate a new surgical and signal processing technique that provides apical stimulation of the cochlea using a cochlear implant without extending the length of the electrode array. PATIENTS Three adult patients who underwent cochlear implantation using this new technique. INTERVENTIONS The patients received a cochlear implant. The surgery differed from the standard approach in that a ground electrode was placed in the cochlear helicotrema via an apical cochleostomy rather than in its typical location underneath the temporalis muscle. Clinical fitting was modified such that low frequencies were represented using the apically placed electrode as a ground. MAIN OUTCOME MEASURES Pitch scaling and speech recognition. RESULTS All surgeries were successful with no complications. Pitch scaling demonstrated that use of the apically placed electrode as a ground lowered the perceived pitch of electric stimulation relative to monopolar stimulation. Speech understanding was improved compared with preoperative scores. CONCLUSIONS The new surgical approach and clinical fitting are feasible. A lower pitch is perceived when using the apically placed electrode as a ground relative to stimulation using an extracochlear ground (i.e., monopolar mode), suggesting that stimulation can be provided more apically without the use of a longer electrode array. Further work is required to determine potential improvements in outcomes and optimal signal processing for the new approach.

Abstract
OBJECTIVE To compare the intraoperative electrically evoked auditory brainstem response (EABR) morphologies between neurofibromatosis II (NF2) adult auditory brainstem implant (ABI) recipients who had auditory percepts post-operatively and those who did not and between NF2 adult ABI recipients and non-NF2 pediatric ABI recipients. METHODS This was a retrospective case series at a single tertiary academic referral center examining all ABI recipients from 1994 to 2016, which included 34 NF2 adults and 11 non-NF2 children. The morphologies of intraoperative EABRs were evaluated for the number of waveforms showing a response, the number of positive peaks in those responses, and the latencies of each of these peaks. RESULTS 27/34 adult NF2 patients and 9/10 children had EABR waveforms. 20/27 (74.0%) of the adult patients and all of the children had ABI devices that stimulated post-operatively. When comparing the waveforms between adults who stimulated and those who did not stimulate, the proportion of total number of intraoperative EABR peaks to total possible peaks was significantly higher for the adults who stimulated than for those who did not (p < 0.05). Children had a significantly higher proportion of total number of peaks to total possible peaks when compared to adults who stimulated (p < 0.02). Additionally, there were more likely to be EABR responses at the initial stimulation than intraoperatively in the pediatric ABI population (p = 0.065). CONCLUSIONS The value of intraoperative EABR tracing may lie in its ability to predict post-operative auditory percepts based on the placement of the array providing the highest number of total peaks.

Abstract
Background: Phase I and Phase II studies in patients with moderate to severe plaque psoriasis demonstrated that intravenous (TV) efalizumab improved clinical signs and symptoms and was well tolerated. Objective: To determine if subcutaneous (SC) delivery of efalizumab improves chronic plaque psoriasis and demonstrates an acceptable safety profile. Methods: This was a Phase I, open-label, single- and multiple-dose, escalating-dose study. Subjects received a single dose of efalizumab (0.3 mg/kg/wk SC) or escalating multiple doses of efalizumab (0.50–2.0 mg/kg/wk SC). Effectiveness was assessed using the Psoriasis Area and Severity Index (PASI), target lesion assessment, and Physician's Global Assessment (PGA). Safety was assessed by evaluating adverse events, clinical laboratory test results, physical examination results, immunologic responses, and vital signs. Results: PASI score, target lesion assessment, and PGA showed improvement of approximately 40%–60% in signs and symptoms of plaque psoriasis by day 56. Mean PASI scores were still declining at the end of the eight-week dosing period, suggesting that longer duration of treatment would be more effective. By day 91, mean PASI scores were 16.2 vs. 14.6 at day 56 in the 0.5–1.0-mg/kg/wk group and 11.7 vs. 10.1 in the 1.0–2.0-mg/kg/wk group. This demonstrates that, on average, patients maintained their treatment benefit during the 42-day followup period. Overall, there were considerably fewer adverse events than in previous IV studies. These consisted principally of mild to moderate headache, pain, and rhinitis. No allergic reactions were observed. Antibodies to efalizumab were observed in only one subject (2%) and did not have any clinical relevance. Conclusion: The SC administration of eight weekly doses of efalizumab improves signs and symptoms of psoriasis. The treatment was safe and very well tolerated. In comparison to previously published results with IV efalizumab, SC administration of efalizumab improves overall safety and tolerability, with the additional advantage of greater convenience.

Abstract
BACKGROUND Glioblastoma is an aggressive and almost universally fatal tumor. The prognosis at the time of recurrence has generally been poor, with overall survival typically in the range of 4-40 weeks. The merits of surgical resection (vs. open biopsy, to confirm recurrence via histology) in addition to conventional adjuvant chemotherapy have been the subject of longstanding debate. We wondered whether it would possible to conduct a trial at our institution to settle this question definitively with Class I evidence. RESULTS Initially, we had hoped to conduct a randomized, unblinded prospective clinical trial. However on closer inspection it appeared that such an undertaking would pose significant practical challenges. Thus we present our protocol in draft form. In keeping with recommended outcomes for these tumors, the primary endpoint would be median progression free survival. Secondary end points would be: median overall survival (mOS, from time of recurrence) and change in Karnofsky Performance Status over time. Patients would be eligible at the time of first recurrence if they had received conventional treatment until that point and at least 1 month had elapsed since the time of radiation. All patients would be considered potentially eligible for enrollment (unless the decision regarding resection was already clear-cut in view of other factors). Using Cox's proportional hazards model, we estimate that at least 456 patients would be necessary to demonstrate an increase in the hazard ratio to 1.3 for those undergoing biopsy alone. This magnitude of benefit is estimated based on a review of retrospective studies. DISCUSSION If restricted to our Institution alone, which sees approximately 100-150 new cases of glioblastoma each year, a trial of this nature would be likely to take around 10 years. Furthermore, there may be significant reluctance on the part of patients and physicians to participate. There is also the opportunity cost of excluding patients from other trials to consider. We recognize that the estimate of the magnitude of effect may be conservative. As things stand, we feel that multi-institutional collaboration would almost certainly be required for an undertaking of this kind.

Abstract
We report a case of Langerhans cell histiocytosis in a 64-year-old male who presented with symptoms and signs of brain involvement, including seizures and hypopituitarism. The diagnosis was confirmed with a biopsy of a lytic skull lesion. The disease affecting the bone showed no sign of progression following a short course of cladribine. Signs of temporal lobe involvement led to an additional biopsy, which showed signs of nonspecific neurodegeneration and which triggered status epilepticus. Lesions noted in the brainstem were typical for the paraneoplastic inflammation reported in this condition. These lesions improved after treatment with cladribine. They remained stable while on treatment with intravenous immune globulin.

Abstract
METHODS Leptomeningeal metastases (LM) in the setting of glioma have often been thought to carry a particularly poor prognosis. We sought to better characterize this phenomenon through a review of patients with glioma seen in our institution over the preceding 10 years. We focus here on 34 cases with LM due to grade III or IV glioma. Over the period in question, we estimate a prevalence of almost 4% in those affected by grade IV tumors. RESULTS Leptomeningeal spread was present at the time of initial diagnosis in 4 patients. Among the others, LM occurred at the time of first progression of disease in 17. The median time to development of LM (excluding those where it was present at initial diagnosis) was 16.4 months [95% confidence interval (CI) 8.2-43.9]. The median time to further progression of disease following LM was 4.9 months (95% CI 3.1-6.9). Twenty-five patients were known to have died at the time of writing. Thus, median overall survival (OS) was 10.2 months (95% CI 8.8-14.7) following LM. At the time of diagnosis of LM, some form of treatment (chemotherapy and/or radiation vs. no treatment) increased OS (median 11.7 vs. 3.3 months, p < 0.001 by log-rank test). Use of radiation therapy (vs. no radiation) also increased OS, although the effect was more modest (7.8 vs. 16.8 months, p = 0.07). Higher Karnofsky Performance Status (KPS) at the time of diagnosis of LM was associated with OS (p = 0.007, median OS for KPS ≥90 19 months vs. 7.8 for KPS <90). In a two-variable model incorporating the use any treatment (vs. none) and KPS, the latter tended to be a more significant predictor of survival (p = 0.22 vs. p = 0.06 by likelihood-ratio test). This was also true for radiation (vs. none) and KPS (p = 0.27 vs. p = 0.02). No significant benefit could be demonstrated for the use of chemotherapy considered alone, either systemic or intrathecal. It should be noted that 4 of 9 patients receiving intrathecal chemotherapy had a ventriculo-peritoneal shunt in place during these injections, which may have reduced its effectiveness. CONCLUSION Overall, treatment appears to improve outcomes. We favor maximal treatment, as tolerated, particularly with a KPS of ≥70. Such treatment would typically include radiation to the maximum tolerated dose, concurrent, and adjuvant chemotherapy (preferably with an alkyating agent), in addition to intrathecal treatment.

Abstract
BACKGROUND This phase I/II trial evaluated the maximum tolerated dose (MTD) and pharmacokinetics of afatinib plus temozolomide as well as the efficacy and safety of afatinib as monotherapy (A) or with temozolomide (AT) vs temozolomide monotherapy (T) in patients with recurrent glioblastoma (GBM). METHODS Phase I followed a traditional 3 + 3 dose-escalation design to determine MTD. Treatment cohorts were: afatinib 20, 40, and 50 mg/day (plus temozolomide 75 mg/m(2)/day for 21 days per 28-day cycle). In phase II, participants were randomized (stratified by age and KPS) to receive A, T or AT; A was dosed at 40 mg/day and T at 75 mg/m(2) for 21 of 28 days. Primary endpoint was progression-free survival rate at 6 months (PFS-6). Participants were treated until intolerable adverse events (AEs) or disease progression. RESULTS Recommended phase II dose was 40 mg/day (A) + T based on safety data from phase I (n = 32). Most frequent AEs in phase II (n = 119) were diarrhea (71% [A], 82% [AT]) and rash (71% [A] and 69% [AT]). Afatinib and temozolomide pharmacokinetics were unaffected by coadministration. Independently assessed PFS-6 rate was 3% (A), 10% (AT), and 23% (T). Median PFS was longer in afatinib-treated participants with epidermal growth factor receptor (EFGR) vIII-positive tumors versus EGFRvIII-negative tumors. Best overall response included partial response in 1 (A), 2 (AT), and 4 (T) participants and stable disease in 14 (A), 14 (AT), and 21 (T) participants. CONCLUSIONS Afatinib has a manageable safety profile but limited single-agent activity in unselected recurrent GBM patients.

Abstract
OBJECT The aim of this study was to determine whether patients with neurofibromatosis Type 2 (NF2) who have intact ipsilateral cochlear nerves can have open-set speech discrimination following cochlear implantation. METHODS Records of 7 patients with documented NF2 were reviewed to determine speech discrimination outcomes following cochlear implantation. Outcomes were measured using consonant-nucleus-consonant words and phonemes; Hearing in Noise Test sentences in quiet; and City University of New York sentences in quiet and in noise. RESULTS Preoperatively, none of the patients had open-set speech discrimination. Five of the 7 patients had previously undergone excision of ipsilateral vestibular schwannoma (VS). One of the patients who received a cochlear implant had received radiation therapy for ipsilateral VS, and another was undergoing observation for a small ipsilateral VS. Following cochlear implantation, 4 of 7 patients with NF2 had open-set speech discrimination following cochlear implantation during extended follow-up (15-120 months). Two of the 3 patients without open-set speech understanding had a prolonged period between ipsilateral VS resection and cochlear implantation (120 and 132 months), and had cochlear ossification at the time of implantation. The other patient without open-set speech understanding had good contralateral hearing at the time of cochlear implantation. Despite these findings, 6 of the 7 patients were daily users of their cochlear implants, and the seventh is an occasional user, indicating that all of the patients subjectively gained some benefit from their implants. CONCLUSIONS Cochlear implantation can provide long-term auditory rehabilitation, with open-set speech discrimination for patients with NF2 who have intact ipsilateral cochlear nerves. Factors that can affect implant performance include the following: 1) a prolonged time between VS resection and implantation; and 2) cochlear ossification.

Abstract
Abstract
Biomarkers that select patients for therapeutics would benefit clinical trial design and patient care. The Akt pathway is a therapeutic target in Glioblastoma Multiforme (GBM) and an important determinant of patient outcome. However, it is not known whether activity of this pathway varies among GBM tumors. To investigate we used Akt pathway genes from published GBM expression datasets. We detected 5 patterns of Akt pathway gene expression and these Akt subgroups correlated with prognosis. We analyzed networks within subgroups using both gene set enrichment analysis and a novel method that scores relevance based on both expression and local network connectivity (Komurov et al., PLoS Comput Biol. 2010 6:8, 1-10). The results suggest therapeutic targets within the individual subgroups. Furthermore, preliminary analysis indicates that human GBM xenograft models and primary human GBM manifest similar Akt subgroups. We are investigating rodent xenograft models of Akt subgroups to evaluate subgroup-specific drug sensitivity, and will present a method and examples of analysis integrating gene expression data from human GBM xenografts and primary human GBM. We hypothesize that Akt subgroups will help personalize treatment for GBM therapeutics. Supported by Barrow Neurological Foundation, Halle Family Foundation, and NIH 1 K01 NS064952-01A1 (AMJ).

Abstract
Mammalian forebrain development requires extensive migration, yet the mechanisms through which migrating neurons sense and respond to guidance cues are not well understood. Similar to the axon growth cone, the leading process and branches of neurons may guide migration, but the cytoskeletal events that regulate branching are unknown. We have previously shown that loss of microtubule-associated protein Lis1 reduces branching during migration compared with wild-type neurons. Using time-lapse imaging of Lis1(+/-) and Lis1(+/+) cells migrating from medial ganglionic eminence explant cultures, we show that the branching defect is not due to a failure to initiate branches but a defect in the stabilization of new branches. The leading processes of Lis1(+/-) neurons have reduced expression of stabilized, acetylated microtubules compared with Lis1(+/+) neurons. To determine whether Lis1 modulates branch stability through its role as the noncatalytic beta regulatory subunit of platelet-activating factor (PAF) acetylhydrolase 1b, exogenous PAF was applied to wild-type cells. Excess PAF added to wild-type neurons phenocopies the branch instability observed in Lis1(+/-) neurons, and a PAF antagonist rescues leading process branching in Lis1(+/-) neurons. These data highlight a role for Lis1, acting through the PAF pathway, in leading process branching and microtubule stabilization.

Abstract
Treating hemodialysis patients to combat anemia corrects hemoglobin but exacerbates iron deficiency by utilizing iron stores. Patients needing iron should receive this by intravenous (i.v.) means. The Dialysis patients' Response to IV iron with Elevated ferritin (DRIVE) trial investigated the role of i.v. iron in anemic patients with high ferritin, low transferrin saturation, and adequate epoetin doses. We examined whether baseline iron and inflammation markers predict the response of hemoglobin to treatment. Patients (134) were randomized to no added iron or to i.v. ferric gluconate for eight consecutive hemodialysis sessions spanning 6 weeks with epoetin increased by 25% in both groups. The patients started with hemoglobin less than or equal to 11 g/dl, ferritin between 500 and 1200 ng/ml, and transferrin saturation of less than 25%. Significantly, patients with a reticulocyte hemoglobin content greater than or equal to 31.2 pg were over five times more likely to achieve a clinically significant increase in hemoglobin of greater than 2 g/dl. Lower reticulocyte hemoglobin contents did not preclude a response to i.v. iron. Significantly higher transferrin saturation or lower C-reactive protein but not ferritin or soluble transferrin receptor levels predicted a greater response; however their influence was not clinically significant in either group. We conclude that none of the studied markers is a good predictor of response to anemia treatment in this patient sub-population.

Abstract
Object. The goals of this study were to analyze outcomes in patients with posterior fossa ependymomas, determine whether gross-total resection (GTR) alone is appropriate treatment, and evaluate the role of radiation therapy.
Methods. All patients with newly diagnosed intracranial ependymomas treated at Barrow Neurological Institute between 1983 and 2002 were identified. Those with supratentorial primary lesions, subependymomas, or neuraxis dissemination were excluded. Forty-five patients met the criteria for the study. Gross-total resection was accomplished in 32 patients (71%) and subtotal resection (STR) in 13 (29%). Radiation therapy was given to 25 patients: 13 following GTR and 12 after STR. The radiation fields were craniospinal followed by a posterior fossa boost in six patients and posterior fossa or local only in the remaining patients.
With a median follow-up period of 66 months, the median duration of local control was 73.5 months with GTR alone, but has not yet been reached for patients with both GTR and radiotherapy (p = 0.020). The median duration of local control following STR and radiotherapy was 79.6 months. The 10-year actuarial local control rate was 100% for patients who underwent GTR and radiotherapy, 50% for those who underwent GTR alone, and 36% for those who underwent both STR and radiotherapy, representing significant differences between the GTR-plus-radiotherapy and GTR-alone cohorts (p = 0.018), and between the GTR-plus-radiotherapy and the STR-plus-radiotherapy group (p = 0.003). There was no significant difference in the 10-year actuarial local control rate between the GTR-alone and STR-plus-radiotherapy cohorts (p = 0.370). The 10-year overall survival was numerically superior in patients who underwent both GTR and radiotherapy: 83% compared with 67% in those who underwent GTR alone and 43% in those who underwent both STR and radiotherapy. These differences did not achieve statistical significance. Univariate analyses revealed that radiotherapy, tumor grade, and extent of resection were significant predictors of local control.
Conclusions. Gross-total resection should be the intent of surgery when it can be accomplished with an acceptable degree of morbidity. Even after GTR has been confirmed with postoperative imaging, however, adjuvant radiotherapy significantly improves local control. The authors currently recommend the use of postoperative radiotherapy, regardless of whether the resection is gross total or subtotal.

Abstract
The purpose of this study was to evaluate the performance of the new features of the Nucleus Research Platform 8 (RP8), a system developed specifically for research purposes The RP8 consists of a research implant, a speech processor and a new NRT software (NRT v4), and includes comparisons of the different artefact-cancellation methods, NRT threshold, and recovery function measurements. The system has new artefact-suppression techniques and new diagnostic capabilities; their performance has been verified in animal experiments. In this study, NRT data were collected from 15 postlingually deafened adult cochlear implant patients intraoperatively and up to 6 months postoperatively after switch-on. The initial investigation in two clinics in Europe focused primarily on the enhanced NRT capabilities Results from the trial in two European clinics indicate that NRT measurements can be obtained with lower noise levels. A comparison of the different artefact-cancellation techniques showed that the forward-masking paradigm implemented in the Nucleus 3 system is still the method of choice. The focus of this report is on recovery function characteristics, which may give insight into auditory nerve fiber properties with regard to higher stimulation rates.

Abstract
OBJECTIVE To evaluate the efficacy of cochlear implants in human immunodeficiency virus-infected individuals and correlate these results with a proposed pathophysiological mechanism of human immunodeficiency virus-associated hearing loss. STUDY DESIGN Retrospective case series and temporal bone analysis of deceased human immunodeficiency virus-positive patients. SETTING Tertiary care hospital. PATIENTS Seven human immunodeficiency virus-positive individuals with profound sensorineural hearing loss. INTERVENTION Cochlear implantation at New York University Medical Center. METHODS The surgical outcomes and complications were analyzed. Additionally, electron microscopic and immunohistochemical findings of cadaver temporal bone specimens of other known human immunodeficiency virus-positive individuals were reviewed. The performance results of the human immunodeficiency virus-positive cochlear implant patients were then correlated with the previously hypothesized pathophysiological mechanism of human immunodeficiency virus-associated hearing loss. RESULTS The patients had a varied performance with cochlear implantation, and as a group performance was good. There were no surgical complications or postoperative complications. The good performance of these patients supports the hypothesis that the mechanism of human immunodeficiency virus-associated deafness involves infiltration, malfunction, and premature degeneration of the hair cells and supportive cells of the cochlea. CONCLUSIONS Human immunodeficiency virus-positive individuals benefit from cochlear implantation without increased surgical risk.

Abstract
BACKGROUND Phase I and Phase II studies in patients with moderate to severe plaque psoriasis demonstrated that intravenous (IV) efalizumab improved clinical signs and symptoms and was well tolerated. OBJECTIVE To determine if subcutaneous (SC) delivery of efalizumab improves chronic plaque psoriasis and demonstrates an acceptable safety profile. METHODS This was a Phase I, open-label, single- and multiple-dose, escalating-dose study. Subjects received a single dose of efalizumab (0.3 mg/kg/wk SC) or escalating multiple doses of efalizumab (0.50-2.0 mg/kg/wk SC). Effectiveness was assessed using the Psoriasis Area and Severity Index (PASI), target lesion assessment, and Physician's Global Assessment (PGA). Safety was assessed by evaluating adverse events, clinical laboratory test results, physical examination results, immunologic responses, and vital signs. RESULTS PASI score, target lesion assessment, and PGA showed improvement of approximately 40%-60% in signs and symptoms of plaque psoriasis by day 56. Mean PASI scores were still declining at the end of the eight-week dosing period, suggesting that longer duration of treatment would be more effective. By day 91, mean PASI scores were 16.2 vs. 14.6 at day 56 in the 0.5-1.0-mg/kg/wk group and 11.7 vs. 10.1 in the 1.0-2.0-mg/kg/wk group. This demonstrates that, on average, patients maintained their treatment benefit during the 42-day followup period. Overall, there were considerably fewer adverse events than in previous IV studies. These consisted principally of mild to moderate headache, pain, and rhinitis. No allergic reactions were observed. Antibodies to efalizumab were observed in only one subject (2%) and did not have any clinical relevance. CONCLUSION The SC administration of eight weekly doses of efalizumab improves signs and symptoms of psoriasis. The treatment was safe and very well tolerated. In comparison to previously published results with IV efalizumab, SC administration of efalizumab improves overall safety and tolerability, with the additional advantage of greater convenience.

Abstract
OBJECTIVE The study investigated the hypothesis that threshold and comfortable levels recorded from cochlear implant patients would reduce, and dynamic range increase, as distance of the electrode from the modiolar wall (radial distance) decreases. Two groups of cochlear implant patients participated; one group using the Nucleus' 24 Contour electrode array, and one group using the Nucleus standard straight (banded) array. The Nucleus 24 Contour array has been shown in temporal bone studies to lie closer to the modiolus than the banded array. The relationship of electrode impedance and radial distance is also investigated. DESIGN The study, conducted at three centers, evaluated 21 patients using the Contour array, and 36 patients using the banded array. For each patient, threshold, comfortable levels and dynamic range were measured at four time points. Common ground electrode impedance was recorded clinically from each patient, at time intervals up to 12 wk. An estimate of the radial distance of the electrode from the modiolus was made by analysis of Cochlear view x-rays. RESULTS Threshold and comfortable levels were significantly lower for the Nucleus 24 Contour array than for the banded array. However, dynamic range measurements did not show the predicted increase. In a majority of subjects, a significant correlation was found between the estimated radial distance of the electrode from the modiolus and the measured threshold and comfortable levels. This trend was not observed for dynamic range. The analysis indicates that other factors than radial distance are involved in the resultant psychophysical levels. Clinical impedance measures (common ground) were found to be significantly higher for the Contour array. However, the electrodes on the Contour array are half-rings, which are approximately only half the geometric size of the full rings as electrodes of the standard array. When the geometric electrode area in the two array designs are normalized, the trends in the electrode impedance behavior are similar. CONCLUSIONS The results support the hypothesis that the relationship between the radial distance of the electrode and the psychophysical measures are influenced by patterns of fibrous tissue growth and individual patient differences, such as etiology and neural survival. Impedance measures for the Nucleus 24 Contour electrode array were higher than the banded electrode array, but this is primarily due to the reduction in electrode surface area. The different outcomes in impedance over time suggest differences in the relative contributions of the components of impedance with the two arrays.

Abstract
BACKGROUND Diagnosis of iron deficiency in hemodialysis patients is limited by the inaccuracy of commonly used tests. Reticulocyte hemoglobin content (CHr) is a test that has shown promise for improved diagnosis in preliminary studies. The purpose of this study was to compare iron management guided by serum ferritin and transferrin saturation to management guided by CHr. METHODS A total of 157 hemodialysis patients from three centers were randomized to iron management based on (group 1) serum ferritin and transferrin saturation, or (group 2) CHr. Patients were followed for six months. Treatment with intravenous iron dextran, 100 mg for 10 consecutive treatments was initiated if (group 1) serum ferritin <100 ng/mL or transferrin saturation <20%, or (group 2) CHr <29 pg. RESULTS There was no significant difference between groups in the final mean hematocrit or epoetin dose. The mean weekly dose of iron dextran was 47.7 +/- 35.5 mg in group 1 compared to 22.9 +/- 20.5 mg in group 2 (P = 0.02). The final mean serum ferritin was 399.5 +/- 247.6 ng/mL in group 1 compared to 304.7 +/- 290.6 ng/mL in group 2 (P < 0.05). There was no significant difference in final TSAT or CHr. Coefficient of variation was significantly lower for CHr than serum ferritin and transferrin saturation (3.4% vs. 43.6% and 39.5%, respectively). CONCLUSIONS CHr is a markedly more stable analyte than serum ferritin or transferrin saturation, and iron management based on CHr results in similar hematocrit and epoetin dosing while significantly reducing IV iron exposure.

Abstract
OBJECTIVES/HYPOTHESIS The most common indication for cochlear reimplantation is device failure. Other, less frequent indications consist of "upgrades" (e.g., single to multichannel), infection, and flap breakdown. Although the percentage of failures has decreased over time, an occasional patient requires reimplantation because of device malfunction. The varying designs of internal receiver/stimulators and electrode arrays mandate an examination of the nature and effects of reimplantation for the individual designs. The purpose of the current study was to investigate the reimplantation of several implant designs and to determine whether differences in surgical technique, anatomical findings, and postoperative performance exist. STUDY DESIGN Retrospective chart review. METHODS The subjects were 33 of 618 severely to profoundly deaf adults and children who had implantation at the New York University Medical Center (New York, NY) between February 1984 and December 2000. The subjects had previously had implantation with either a single-channel 3M/House (House Ear Institute, Los Angeles, CA) or 3M/Vienna (Technical University of Vienna, Vienna, Austria) device or with one of the multichannel Clarion (Advanced Bionics, Sylmar, CA), Ineraid (Smith & Nephew Richards, TN), or Nucleus (including the Contour) devices (Cochlear Corp., Englewood, CO) before reimplantation. RESULTS Length of use before reimplantation ranged from 1 month to 13 years and included traumatic and atraumatic (electronic) failures, as well as device extrusion or infection. Results indicated that postoperative performance was either equal to or better than scores before failure. None of the devices explanted caused damage that precluded the implantation of the same or an upgraded device. These findings support the efficacy and safety of internal implant designs as related to the maintenance of a functional cochlea for the purpose of reimplantation. CONCLUSIONS Cochlear reimplantation can be performed safely and without decrement to performance. The number of implanted electrodes at reinsertion were either the same or greater in all cases.

Abstract
DepoCyte is a slow-release formulation of cytarabine designed for intrathecal administration. The goal of this multi-centre cohort study was to determine the safety and efficacy of DepoCyte for the intrathecal treatment of neoplastic meningitis due to breast cancer. DepoCyte 50 mg was injected once every 2 weeks for one month of induction therapy; responding patients were treated with an additional 3 months of consolidation therapy. All patients had metastatic breast cancer and a positive CSF cytology or neurologic findings characteristic of neoplastic meningitis. The median number of DepoCyte doses was 3, and 85% of patients completed the planned 1 month induction. Median follow up is currently 19 months. The primary endpoint was response, defined as conversion of the CSF cytology from positive to negative at all sites known to be positive, and the absence of neurologic progression at the time the cytologic conversion was documented. The response rate among the 43 evaluable patients was 28% (CI 95%: 14-41%); the intent-to-treat response rate was 21% (CI 95%: 12-34%). Median time to neurologic progression was 49 days (range 1-515(+)); median survival was 88 days (range 1-515(+)), and 1 year survival is projected to be 19%. The major adverse events were headache and arachnoiditis. When drug-related, these were largely of low grade, transient and reversible. Headache occurred on 11% of cycles; 90% were grade 1 or 2. Arachnoiditis occurred on 19% of cycles; 88% were grade 1 or 2. DepoCyte demonstrated activity in neoplastic meningitis due to breast cancer that is comparable to results reported with conventional intrathecal agents. However, this activity was achieved with one fourth as many intrathecal injections as typically required in conventional therapy. The every 2 week dose schedule is a major advantage for both patients and physicians.

Abstract
A randomized, multicentre, open-label, phase II study compared temozolomide (TMZ), an oral second-generation alkylating agent, and procarbazine (PCB) in 225 patients with glioblastoma multiforme at first relapse. Primary objectives were to determine progression-free survival (PFS) at 6 months and safety for TMZ and PCB in adult patients who failed conventional treatment. Secondary objectives were to assess overall survival and health-related quality of life (HRQL). TMZ was given orally at 200 mg/m(2)/day or 150 mg/m(2)/day (prior chemotherapy) for 5 days, repeated every 28 days. PCB was given orally at 150 mg/m(2)/day or 125 mg/m(2)/day (prior chemotherapy) for 28 days, repeated every 56 days. HRQL was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30 [+3]) and the Brain Cancer Module 20 (BCM20). The 6-month PFS rate for patients who received TMZ was 21%, which met the protocol objective. The 6-month PFS rate for those who received PCB was 8% (P = 0.008, for the comparison). Overall PFS significantly improved with TMZ, with a median PFS of 12.4 weeks in the TMZ group and 8.32 weeks in the PCB group (P = 0.0063). The 6-month overall survival rate for TMZ patients was 60% vs. 44% for PCB patients (P = 0.019). Freedom from disease progression was associated with maintenance of HRQL, regardless of treatment received. TMZ had an acceptable safety profile; most adverse events were mild or moderate in severity.

Abstract
PURPOSE To evaluate the efficacy and safety of a slow-release formulation of cytarabine (DepoCyt; Chiron Corp, Emeryville, CA, and Skye Pharma, Inc, San Diego, CA) that maintains cytotoxic concentrations of cytarabine (ara-C) in the CSF of most patients for more than 14 days. PATIENTS AND METHODS Twenty-eight patients with lymphoma and a positive CSF cytology were randomized to receive DepoCyt 50 mg once every 2 weeks or free ara-C 50 mg twice a week for 1 month. Patients whose CSF cytology converted to negative and who did not have neurologic progression received an additional 3 months of consolidation therapy and then 4 months of maintenance therapy. All patients received dexamethasone 4 mg orally bid on days 1 through 5 of each 2-week cycle. RESULTS The response rate was 71% for DepoCyt and 15% for ara-C on an intent-to-treat basis (P =.006). All of the patients on the DepoCyt arm but only 53% of those on the ara-C arm were able to complete the planned 1-month induction therapy regimen. Time to neurologic progression and survival trend in favor of DepoCyt (median, 78.5 v 42 days and 99.5 v 63 days, respectively; P >.05). DepoCyt treatment was associated with an improved mean change in Karnofsky performance score at the end of induction (P =.041). The major adverse events on both arms were headache and arachnoiditis, which were often caused by the underlying disease. CONCLUSION DepoCyt injected once every 2 weeks produced a high response rate and a better quality of life as measured by Karnofsky score relative to that produced by free ara-C injected twice a week.

Abstract
An 11-year-old castrated male Dachshund was determined to have pancytopenia on the basis of results of CBC and bone marrow cytologic examination. Pancytopenia was believed to have resulted from administration of captopril, which had been administered for treatment of chronic mitral insufficiency, because other causes of pancytopenia were not found. Treatment consisted of discontinuing captopril and stimulating the bone marrow with recombinant human erythropoietin and granulocyte colony-stimulating factor. Although neutralizing antibodies will develop against the heterologous human protein, recombinant human granulocyte colony-stimulating factor should be considered for short-term treatment of neutropenias associated with adverse drug reactions, canine parvovirus infections, and bone marrow suppression from primary bone marrow disease, cancer chemotherapy, or total body irradiation before bone marrow transplantation.

Abstract
We tested the hypothesis that the level of the DNA repair protein O6-alkylguanine-DNA alkyltransferase in brain tumors was correlated with resistance to carmustine (BCNU) chemotherapy. Alkyltransferase levels in individual cells in sections from 167 primary brain tumors treated with BCNU were quantitated with an immunofluorescence assay using monoclonal antibodies against human alkyltransferase. Patients with high levels of alkyltransferase had shorter time to treatment failure (P = 0.05) and death (P = 0.004) and a death rate 1.7 times greater than patients with low alkyltransferase levels. Furthermore, the size of the subpopulation of cells with high levels of alkyltransferase was correlated directly with drug resistance. For all tumors the variables most closely correlated with survival, in order of importance, were age, tumor grade, and alkyltransferase levels. For glioblastoma multiforme, survival was more strongly correlated with alkyltransferase levels than with age. These results should encourage prospective studies to evaluate alkyltransferase levels as a method, for identifying brain tumor patients with the best likelihood of response to BCNU chemotherapy.

Abstract
The efficacy and safety of once-daily doses of 200, 300, and 400 mg of bepridil hydrochloride were compared with placebo in a 14-week multi-center, double-blind parallel study. All doses of bepridil significantly reduced weekly anginal attacks and nitroglycerin consumption from baseline levels. Bepridil also significantly improved total exercise time, time to angina, time to 1 mm ST-segment depression, and total work. Reduction in heart rate (maximum mean decreases of 7-8 beats/min) and prolongation of QT and corrected QT (QTc) intervals were associated with bepridil therapy. Bepridil was well tolerated; most adverse reactions reported were mild and tolerable even at the 400-mg dose. This study provides strong support for the use of bepridil in patients with chronic stable angina pectoris that is not optimally controlled by other available antianginal therapies. A double-blind withdrawal study is also reported, in which patients stabilized on bepridil were randomized to either continue on bepridil therapy or receive placebo. Patients who were withdrawn from bepridil therapy showed significant increases in the number of weekly anginal attacks and nitroglycerin consumption compared with levels seen during long-term treatment. Patients withdrawn from bepridil therapy showed significant deterioration in exercise tolerance compared with baseline and with those maintained on bepridil.

Abstract
A Phase I study of interstitial thermoradiotherapy for high-grade supratentorial gliomas has been completed. The objective of this trial was to test the feasibility and toxicity of hyperthermia induced by ferromagnetic implants in the treatment of intracranial tumors. The patient population consisted of 16 males and 12 females, with a median age of 44 years and a median Karnofsky score of 90. Nine patients had anaplastic astrocytoma while 19 had glioblastoma multiforme. Twenty two patients were treated at the time of their initial diagnosis with a course of external beam radiotherapy (median dose 48.4 Gy) followed by an interstitial implant with Ir-192 (median dose 32.7 Gy). Six patients with recurrent tumors received only an interstitial implant (median dose 40 Gy). Median implant volume for all patients was 55.8 cc and median number of treatment catheters implanted per tumor was eighteen. A 60-minute hyperthermia treatment was given through these catheters just before and right after completion of brachytherapy. Time-averaged temperatures of all treatments were computed for sensors located within the core of (> 5 mm from edge of implant), and at the periphery of the implant (outer 5 mm). The percentage of sensors achieving an average temperature > 42 degrees C was 61% and 35%, respectively. Hyperthermia was generally well tolerated; however, there have been 11 minor toxicities, which resolved with conservative management, and one episode of massive edema resulting in the death of a patient. In addition, there were three major complications associated with the surgical implantation of the catheters. Preliminary survival analysis shows that 16 of the 28 patients have died, with a median survival of 20.6 months from diagnosis. We conclude that interstitial hyperthermia of brain tumors with ferromagnetic implants is feasible and carries significant but acceptable morbidity given the extremely poor prognosis of this patient population.

Abstract
Epidural cord compression from germ cell tumor metastases is not common. Treatment usually requires high dose corticosteroids with radiation therapy and/or surgical decompression. Three patients with epidural germ cell tumor metastases were treated with cisplatin-based chemotherapy and all three had complete neurologic recovery. Systemic chemotherapy should be considered as initial therapy with corticosteroids for epidural cord compression from metastatic germ cell tumor.

Abstract
The records of 15 sequential cases of transitional cell carcinoma of the urinary bladder or urethra in dogs were examined to determine the results of treatment with cisplatin (cisdiamminedichloroplatinum) and to record and assess toxicities. All dogs had measurable disease and were considered eligible for evaluation of toxicity following one cisplatin treatment. Three dogs were eliminated from evaluation of efficacy because of acute toxicities. Of the 12 remaining dogs that received two or more cisplatin treatments, evaluations at the end of the second month of treatment revealed no complete responses; however, three dogs showed partial responses and six dogs maintained stable disease. Three dogs had tumor progression. The median survival time for these 12 dogs was 180 days (mean, 220 days; range, 36 to 589 days). Three dogs were azotemic before treatment. Two of these dogs showed improvement in renal function following therapy. Six of the other twelve dogs developed increases in serum creatinine during therapy. The objective and subjective improvements of some dogs to cisplatin chemotherapy suggest that this agent is active in selected dogs with transitional cell carcinomas of the urinary tract.

Abstract
Nine children received the Nucleus multichannel cochlear prosthesis. The preoperative evaluation consisted of assessments of auditory function, speech recognition, linguistic skills, and speech production. There were no surgical complications, and recovery in all patients was uneventful. The device was programmed 4 to 5 weeks following surgery, and all children were conditioned to the task. Postoperative training began immediately following device stimulation and is ongoing. Auditory skills and speech production scales were devised to monitor each child's progress. All children have shown varying degrees of improvement in auditory skills and speech production using the implant alone.

Abstract
The antiangina effects of atenolol, 50 to 200 mg once daily, or nifedipine, 10 to 30 mg 3 times daily, were evaluated in a multicenter, randomized, double-blind, parallel study of 39 patients with known symptomatic coronary artery disease. Treatment was titrated to produce at least a 30% increase in treadmill exercise duration over placebo baseline and then maintained at that dosage for an additional 3 weeks. Both treatments produced significant (p less than 0.001) increases in duration of exercise, total work and exercise capacity when compared with placebo baseline. These improvements in exercise performance were obtained with significant (p less than 0.001) reductions in both ST-segment depression and rate-pressure product for atenolol compared with nifedipine. Furthermore, the total angina attack rate and rate at rest were significantly (p less than 0.01) less frequent with atenolol than with nifedipine. Hence, the antiischemic effects of atenolol exceeded those of nifedipine, based on ST-segment depression and rate-pressure product at comparable workloads.

Abstract
Labetalol is a non-selective beta-adrenoceptor antagonist agent with added alpha 1-adrenergic blocking properties, beta 2-stimulating action, and direct vasodilatory activity. A multi-center, double-blind, parallel group study compared the safety and efficacy of labetalol to propranolol in the treatment of patients with both exertional angina and mild to moderate systemic hypertension. An initial 4 to 5 week placebo washout phase was followed by a five week titration phase and a four month maintenance phase. Labetalol and propranolol had similar effects in reducing supine and standing blood pressures, except for a greater reduction in standing systolic blood pressure seen in the labetalol group. There were comparable effects by both treatments on angina attacks, nitroglycerin use, and exercise tolerance. Adverse effects were frequent with both drugs, but were generally minor. Thus, labetalol appears to be an effective alternative to propranolol in the treatment of patients with coexisting angina pectoris and hypertension, with the choice of agent dependent on the clinical situation.
