RESUMO
We present a 31-year-old female patient with primary glioblastoma multiforme (GBM) of the thoracic spine, diagnosed in approximately mid-2020. Her symptoms began several months prior with right foot paresthesia, which progressed to neuropathy ascending from her distal to proximal right lower extremity. Over several months, she developed lumbo-thoracic throbbing pain, which was dermatomal radiating anteriorly. Her pain worsened with activity. A thoracic spine MRI showed a focus of abnormal intradural intramedullary enhancement present from the T10-T11 disc level to the T12-L1 disc level, producing a large amount of edema within the cord. She underwent a gross total surgical resection. The patient had WHO Grade IV spinal GBM per histopathology. The patient received adjuvant concurrent radiation therapy and temozolomide chemotherapy. She continues with maintenance temozolomide along with the compassionate use of Novocure alternating electrical field therapy for the spine. She is being monitored closely by a multi-specialty team. At 32 months post-radiation therapy, her disease is stable with no evidence of progression. She has made significant improvements in her ambulation and symptoms. While GBM is most commonly intracranial, primary spinal GBM is relatively rare. Although established treatment guidelines exist for supratentorial GBM, treatment protocol choices for spinal GBM remain controversial but typically mirror those used for intracranial GBM and include surgery, radiation therapy, and chemotherapy. Alternating electrical field therapy, also known as tumor-treating fields (TTFields), is indicated for adjuvant treatment of intracranial GBM. While further studies of TTFields in spinal GBM are needed, TTFields appear to be a safe adjunct treatment for spinal GBM. Further studies are still needed aimed at finding an improved treatment for spinal GBM.
RESUMO
Elderly patients with Alzheimer's disease (AD) and other dementias are at high risk of polypharmacy and excessive polypharmacy for common coexisting medical conditions. Polypharmacy increases the risk of drug-drug and drug-disease interactions in these patients who may not be able to communicate early symptoms of adverse drug events. Three acetylcholinesterase inhibitors (ACHEIs) have been approved for AD: donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne). They are also used off-label for other causes of dementia such as Lewy body and vascular dementia. We here report evidence from the literature that ACHEI treatment, prescribed for cognitive impairment, can reduce the load of medications in patients with AD by also addressing cardiovascular, gastrointestinal, and other comorbidities. Using one drug to address multiple symptoms can reduce costs and improve medication compliance.
