Hemiballism/Hemichorea (HH) is a hyperkinetic movement disorder observed mostly after cerebrovascular diseases in elderly patients. Even though the improvement in symptoms would be maintained without treatment, in rare cases, lesioning or DBS (deep brain stimulation) surgery provide a chance on relieving the severe involuntary movements. HH is a more rarely reported entity as a diabetic complication and we encountered very few cases treated with surgical intervention for diabetic HH. A 75-year-old female patient with type-II diabetes mellitus was admitted for left-sided disabling involuntary movement despite being medically treated for six months...

In the last decades there has been progress in the treatment of essential tremor (TE) especially in the surgical field and to a lesser extent in the pharmacological field. We carry out a review of the currently available treatments. The first intervention is the use of non-pharmacological and non-surgical strategies (general advice, occupational therapy, speech therapy, psychotherapy). With discrete advances, the pharmacological treatment is not very satisfactory. Only 30-60% of patients have a positive response, and in these the anti-tremor effectiveness is 40-60%...

PURPOSE: Covid-19 has affected all people, especially those with chronic diseases, including Parkinson's Disease (PD). Covid-19 may affect both motor and neuropsychiatric symptoms of PD patients. We intend to evaluate different aspects of Covid-19 impact on PD patients. METHODS: 647 PD patients were evaluated in terms of PD-related and Covid-19-related clinical presentations in addition to past medical history during the pandemic through an online questioner. They were compared with an age-matched control group consist of 673 individuals and a sample of the normal population consist of 1215 individuals...

INTRODUCTION AND OBJECTIVE: Pudendal neuralgia is a severely intense, painful, neuropathic condition, involving the dermatome of the pudendal nerve (S2, S3, S4). The diagnosis is complex and usually takes many years to be made. Techniques that use electrical current have been shown to decrease pain and improve quality of life in patients with this condition. The aim of this review was to analyze the existing literature on the effects of electrical current in the treatment of patients with pudendal neuralgia...

Permanent pacemakers are a frequently used therapeutic modality. Its use has had a great impact on the morbidity and mortality and quality of life of patients with heart rhythm disturbances, with an exponential increase observed in recent decades. The use of this strategy presents different phases, in which follow-up throughout the useful life of the device is a fundamental and determinant pillar of the efficacy and safety of this therapeutic modality. This review seeks to provide a clear and structured update of the fundamental aspects to consider in the follow-up of all patients with pacemakers...

OBJECTIVES: Report the incidence of symptomatic and asymptomatic intracerebral hemorrhage (ICH) in patients submitted to deep brain stimulation (DBS) guided with microelectrode recording (MER) with further analysis of potential risk factors, both inherent to the patient and related to the pathology and surgical technique. METHODS: We performed a retrospective observational study. 297 DBS procedures were concluded in 277 patients in a single hospital centre between January 2010 and December 2020...

INTRODUCTION: Parkinson's disease (PD) and schizophrenia can coexist. Antipsychotics block striatal D2 receptors, which inevitably aggravates the manifestations of PD. CASE REPORT: We report the case of a male patient with idiopathic Parkinson's disease and schizophrenia, with poor tolerance to minimal doses of levodopa, who underwent a dramatic improvement after bilateral subthalamic deep brain stimulation (DBS-STN). DBS-STN was taken into consideration here, due to the severity of this particular case, as the only possible way to achieve motor improvement...

INTRODUCTION: Repetitive transcranial magnetic stimulation (rTMS) has been used as a potential treatment for tinnitus; however, its effectiveness is variable and unpredictable. We hypothesized that resting-state functional connectivity before rTMS may be correlated with rTMS treatment effectiveness. METHODS: We applied 1-Hz rTMS to the left primary auditory (A1) and dorsolateral prefrontal cortices (DLPFC) of 10 individuals with tinnitus and 10 age-matched controls...

INTRODUCTION: Subthalamic nucleus (STN) and globus pallidus internus (GPi) deep brain stimulation (DBS) are the main surgical approaches for advanced Parkinson's disease. Stimulation is usually applied bilaterally in the same brain structure. However, when various motor symptoms concomitantly present in the same patient, simultaneous modulation of different brain structures may be a suitable alternative. CASE REPORT: We present a patient with advanced Parkinson's disease with a combined DBS neurosurgery...

INTRODUCTION AND OBJECTIVES: Transcatheter aortic valve implantation (TAVI) using the cusp overlap technique (COT) has shown a lower pacemaker implantation rate at 30 days. The objective of this study was to compare electrocardiogram changes and clinical outcomes between COT and the traditional technique (TT) at 1 year of follow-up. METHODS: Observational, retrospective, nonrandomized study of consecutive patients undergoing TAVI between January 2015 and January 2021...

BACKGROUND: Parkinson's disease is poorly studied in Colombia. It is pharmacologically managed, but for refractory cases, surgery is a therapeutic option, positively impacting on quality of life. OBJECTIVE: To determine the impact of deep brain stimulation as management in the control of progression in patients with Parkinson's disease attended our institution between the years 2014 to 2020. METHOD: Descriptive retrospective study, with patients collected between 2014 and 2020 undergoing deep brain stimulation surgery...

This guide provides help for medical doctors systematically identifying each commercial brand of pacemakers by thoracic radiography through their electronic components (electrode connectors, logic circuit, and battery); this is crucial for watching the pacemaker after being implanted. We aimed to describe the different cardiac stimulation devices, electrodes, and programming modes more frequently used.

BACKGROUND: Fibromyalgia syndrome (FM) is a chronic pathology characterized by widespread pain commonly associated with psychological distress affecting quality of life. In recent years, transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) have been investigated to treat chronic pain. The aim of the current review is to determine the effects of tDCS and TMS on the main symptoms of patients with FM. DEVELOPMENT: A systematic review based on PRISMA guidelines was carried out...

INTRODUCTION: The role of the central and peripheral nervous system in the generation of migraine is not well understood. Our aim was to determine whether peripheral trigeminal nerve stimuli, such as nasopharyngeal swabs, could trigger migraine attacks. SUBJECTS AND METHODS: A survey was sent to 658 doctors, nurses and medical students, asking about the presence of headache suggestive of migraine after carrying out a SARS-CoV-2 swab test, their previous history of migraine, and demographic and headache-related characteristics...

BACKGROUND: Traditionally, most centers would use microelectrode recording (MER) to refine targeting in deep brain stimulation (DBS) surgery. In recent years, intraoperative imaging (IMG) guided DBS has become an alternative way to verify lead placement. Currently, there is still controversy surrounding the necessity of MER or IMG for DBS. This meta-analysis aims to explore lead accuracy, clinical efficacy and safety between IMG and MER guided DBS for Parkinson's disease (PD). METHODS: PubMed, Embase, Web of Science, Cochrane Library were searched up to Mar, 2021 for studies reporting comparisons between IMG and MER guided DBS for PD...

BACKGROUND AND OBJECTIVE: Intraoperative neurophysiological monitoring allows us to predict the functional status of the facial nerve after vestibular schwannoma surgery. Due to the great variability of the neurophysiological protocols used for it, the goal of this study is to determine the prognostic ability of our neurophysiological protocol. MATERIAL AND METHODS: We have performed a statistical analysis of the neurophysiological monitoring data collected from patients operated between March 2009 and July 2021 at the Neurosurgery Service of Salamanca according to their functional status, both in the immediate post-surgical period and one year after surgery...

Cluster headache (CH) is included under section 3 - Trigeminal autonomic cephalalgias (TAC) of the International Headache Society (IHS) classification. It is one of the most frequent, painful and disabling primary headaches. Acute and preventive pharmacological treatments are often poorly tolerated and of limited effectiveness. Due to improved understanding of the pathophysiology of CH, neuromodulation devices are now considered safe and effective options for preventive and acute treatment of CH. In this paper, we review the information available to date, and present the case of a patient with disabling cluster headache highly resistant to medical treatment who underwent implantation of a peripheral nerve neurostimulation system to stimulate the supraorbital nerves (SON) and greater occipital nerve (GON) in our Pain Unit...

INTRODUCTION AND OBJECTIVES: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a recognized treatment for drug-refractory Parkinson's disease (PD). However, the therapeutic success depends on the accuracy of targeting. This study aimed to evaluate potential accuracy differences in the placement of the first and second electrodes implanted, by comparing chosen electrode trajectories, STN activity detected during microelectrode recording (MER), and the mismatch between the initially planned and final electrode positions on each side...

BACKGROUND: Right ventricular pacing is associated with risk of heart failure and left ventricular dysfunction. Left bundle branch area pacing (LBBP) has emerged as an alternative method for delivering physiological pacing. The effect of LBBP on N-terminal pro-brain natriuretic peptide (NT-proBNP) has not been investigated. METHOD: Finally, 50 patients referred for pacemaker implantation were included. LBBP was performed as described previously by Huang et al. Transthoracic echocardiogram and NT-proBNP were performed before and four weeks after the procedure...
