Glial tumors and deep brain stimulation: An increasingly recognized association?

Publication date: Available online 24 April 2019Source: Journal of Clinical NeuroscienceAuthor(s): Mehmet Osman Akçakaya, Assel Saryyeva, Hans E. Heissler, Elvis J. Hermann, Joachim K. KraussAbstractOccurrence of gliomas in patients with chronic deep brain stimulation (DBS) has been reported few. It has been speculated whether there could be a causal relationship. Here, we report the development of a pilocytic astrocytoma in close vicinity of a DBS electrode during the course of chronic DBS. A 38-year-old man with refractory dystonic head tremor underwent bilateral implantation of quadripolar DBS electrodes in the thalamic ventral intermediate nucleus. He benefited markedly from chronic DBS. At age 46 he was admitted with head and neck pain, attention deficits and sensory disturbances. Cranial computed tomography and magnetic resonance imaging (MRI) showed a subcortical tumor originating from the right pulvinar. Surgery was performed with neuronavigation guidance and the tumor was subtotally removed. The neuropathological examination revealed a pilocytic astrocytoma WHO Grade I. Postoperative MRI demonstrated a small remnant tumor without increase in size during 1 year follow-up after adjuvant radiation therapy. He had ongoing benefit of his tremor with continued DBS. To our knowledge, there have been only three case reports published before indicating such a co-occurrence. In all of these reports, the tumors were high-grade gliomas. It is estimated that about 160.00...

Authors: Nakamura H, Utsunomiya A, Ishida Y, Horita T Abstract A 48-year-old man was brought to our emergency room with acute abdominal pain and systemic edema, indicating acute circulatory failure with lactic acidosis. Furosemide treatment paradoxically worsened the systemic edema and induced confusion. He had no drinking history but hardly ate legumes or meats containing thiamine. Administration of fursultiamine dramatically improved the symptoms and subsequently caused pulmonary edema. Thiamine deficiency may occur in nondrinkers with an unbalanced diet. In this condition, diuretic therapy can worsen the symptom...

We describe the case of a 52-year-old female outpatient who developed OIC while receiving oxycodone for pain due to cancer with multiple bone metastases. Although she did not have brain metastasis, opioid withdrawal syndrome (OWS) developed after taking naldemedine orally. Her Clinical Opiate-Withdrawal Score (COWS) was 19 (moderate symptoms). However, she recovered from OWS on intravenous fentanyl and a continuous infusion of oxycodone. She did not develop OWS thereafter and was discharged two days after recovery.

Authors: Hotta T, Okimoto T, Hamaguchi M, Tsubata Y, Isobe T Abstract A 40-year-old Japanese man with advanced pulmonary adenocarcinoma harboring anaplastic lymphoma kinase (ALK)-rearranged was administered the selective ALK inhibitor ceritinib as a third-line treatment and continued treatment for nine months. After fourth-line treatment, we performed rechallenge with ceritinib as a fifth-line treatment. On day 54 after rechallenge, the patient developed acutely deteriorating dyspnea. Chest computed tomography showed extensive ground-glass opacities. We diagnosed him with ceritinib-induced interstitial lung disease...

Authors: Kim J, Kim SR, Lee H, Nam DH Abstract Objectives: Acupuncture is often used for relieving symptoms of fibromyalgia syndrome (FMS). Our aim is to ascertain whether verum acupuncture is more effective than sham acupuncture in FMS. Methods: We collected RCTs to investigate the effects of verum acupuncture and sham acupuncture on pain, sleep quality, fatigue, and general status in FMS patients. The databases used for data retrieval were PubMed, Central Cochrane, EMBASE, PsycINFO, CNKI, VIP, OASIS, KoreaMed, and RISS. Selection/exclusion from the retrieved records was performed according to prespecified cri...

This study is the first report to investigate current practice patterns and approach of Korean medicine doctors to CDH treatment. This data may be of significance to Korean medicine doctors in drawing clinical guidelines and conducting randomized controlled trials (RCTs) to generate high-level evidence on the effectiveness of nonsurgical integrative medicine treatments for CDH.

Abstract Chronic pancreatitis is a complex and irreversible disease of the pancreas and is associated with significant morbidity and mortality. Nutrition deficiencies in chronic pancreatitis are common and can be atypical in nature. As such, the management of these deficiencies can be individualized for patients. The aim of this review is to discuss the components of nutrition deficiencies in chronic pancreatitis, their management, and the current areas of research that are being explored. The clinical guidelines of major national and international societies were analyzed for recommendations on the nutrition manag...

ConclusionsIn our experience, patients with PSM after PN can be managed conservatively with satisfactory long-term oncological outcomes.ResumenIntroducciónLa nefrectomía parcial (NP) es el tratamiento de elección para el tumor renal pequeño y localizado (cT1). Uno de los puntos de debate respecto a esta técnica es el manejo de los márgenes de resección afectados/positivos (MP). Presentamos los resultados oncológicos a largo plazo en pacientes con MP tras NP manejados conservadoramente.Material y métodosEn nuestro centro entre el año 1990 y 2011 se realiz...

WalterAbstractSpinal cord stimulation (SCS) is an evidence-based, reversible but invasive procedure for the treatment of chronic pain syndromes: for example, in patients with failed-back-surgery syndrome or complex regional pain syndrome. A more recent, similar technique uses high-frequency stimulation for SCS and follows a different mechanism of action that does not result in paresthesia. This Technical Note and vi...
