Brachytherapy in the Treatment of Recurrent Solitary Brain Metastases
Abstract Conventional therapy for solitary brain metastases includes radiotherapy and surgical resection in selected cases. Often, however, the metastasis recurs and limits the quality of life and survival of the patient. Once the metastasis recurs, therapeutic options are limited. Brachytherapy delivers a high total dose of radiation to a localized area, allowing reirradiation at the time of recurrence. Three patients with recurrent brain metastases treated with iridium-192 implants are presented; two of these patients had breast carcinoma and one had malignant melanoma. The implants allowed long term survival in the two patients with recurrent metastatic breast carcinoma. Unfortunately, the patient with melanoma did not respond to the brachytherapy and died within 7 months of implantation. The approaches to treatment to metastatic brain tumors and the rationale for using brachytherapy are discussed

Metamorphopsia and Palinopsia: Association With Periodic Lateralized Epileptiform Discharges in a Patient With Malignant Astrocytoma
• A patient with a right parietal glioma developed palinopsia and various forms of metamorphopsia that were temporally related to the electrographic presence of periodic lateralized epileptiform discharges. These symptoms occurred in an alert woman with normal visual fields. The literature shows that epileptic events can produce these symptoms. We believe that continuous repetitive electrical stimulation caused our patient's unusual symptoms by altering the association pathways through which visual data are experienced. To our knowledge, the association between periodic lateralized epileptiform discharges and metamorphopsia or palinopsia has heretofore not been reported
Dendritic cell vaccine for recurrent high-grade gliomas in pediatric and adult subjects: clinical trial protocol
Although there have been significant advances in understanding the basic pathogenesis of glioblastoma multiforme, the median survival of patients has changed little in the past 25 years. Recent studies have suggested that immune modulation through dendritic cell (DC) vaccines may stimulate the immune system against tumor antigens and potentially increase survival.
To determine whether the use of adjuvant vaccination with autologous DCs (matured in situ after being loaded with tumor cell lysate derived from autologous refractory gliomas) is safe, feasible, and beneficial for adult and pediatric patients with recurrent high-grade gliomas.
The study design is a single-center, nonrandomized, open phase I clinical trial. A total of 20 patients with malignant gliomas will be enrolled preoperatively over 2 years. Patients will be given adjuvant vaccination with autologous DCs loaded with tumor lysate after maximal safe surgical resection.
Using topical imiquimod before vaccination, it is anticipated that the immune response in vaccinated patients and potentially Overall survival will be greater than that demonstrated in the literature. We anticipate that there will be minimal side effects (minor dermatitis) associated with this treatment.
In the current trial, we assess immune response, safety, and survival using a novel vaccine protocol developed in Belgium that seems to markedly increase survival of certain subjects. Nevertheless, larger randomized clinical studies need to be performed to evaluate fully the efficacy of this therapy for both recurrent and newly diagnosed glioblastoma

Central Nervous System Involvement by Small Lymphocytic Lymphoma after a Myxoma-Related Embolic Event
Involvement of the central nervous system by chronic lymphocytic leukemia/small lymphocytic lymphoma is exceedingly rare, and currently no risk factors have been described. We report the case of a patient with concomitant chronic lymphocytic leukemia/small lymphocytic lymphoma and an embolic cerebrovascular accident related to a cardiac myxoma, who developed parenchymal central nervous system involvement of lymphoma on the ischemic bed. The patient was successfully treated with a high-dose fludarabine-based chemotherapy regimen, achieving a sustained remission. We propose that embolic breakage of the blood-brain barrier may be a major risk factor in producing central nervous system involvement. We also propose that a high-dose fludarabine-based chemotherapy regimen may be adequate to achieve a better CNS penetration and improved outcomes

Opsoclonus-myoclonus-encephalopathy induced by cefepime
•Opsoclonus might be associated with cefepime neurotoxicity.•Cefepime neurotoxicity most commonly presents with myoclonus and encephalopathy.•Continuous video-EEG is vital to monitor for non-convulsive status epilepticus.•Cefepime neurotoxicity occurs in susceptible patients despite normal renal clearance
