Este artículo resume la guía de práctica clínica (GPC) para el diagnóstico y manejo de pacientes con osteoartritis (OA) del Seguro Social del Perú (EsSalud). Para su desarrollo se conformó un grupo elaborador de la guía (GEG) que incluyó a especialistas clínicos y metodólogos. Para responder las 13 preguntas clínicas planteadas se realizaron búsquedas sistemáticas en PubMed y repositorios de GPC. Se usó la metodología Grading of Recommendations Assessment, Development, and Evaluation (GRADE) para evaluar la certeza de la evidencia. Se emitieron 11 recomendaciones: tres fuertes (no solicitar de forma rutinaria radiografías para el diagnóstico de OA, brindar un plan individualizado de medidas de educación y autocuidado, indicar la realización de ejercicio físico) y ocho débiles (intervenciones para reducir el peso en personas con obesidad o sobrepeso, evitar el uso de paracetamol para el manejo de OA, promover el uso de AINE orales para el manejo de OA, evitar el uso de condroitín sulfato para el manejo de OA, evitar el uso de proloterapia para el manejo de OA, en adultos con OA y dolor refractario a manejo farmacológico considerar terapias adyuvantes como ultrasonido o similares, evitar el uso de terapia laser como adyuvante para el manejo de OA, evitar el uso de acupuntura para el manejo de OA); además, 20 puntos de buena práctica clínica y un flujograma de trabajo.

Neuromodulation Techniques in Phantom Limb Pain: A Systematic Review and Meta-analysis

Pain Medicine (2020)

Kevin Pacheco‐Barrios Xianguo Meng Felipe Fregni

To evaluate the effects of neuromodulation techniques in adults with phantom limb pain (PLP).A systematic search was performed, comprising randomized controlled trials (RCTs) and quasi-experimental (QE) studies that were published from database inception to February 2019 and that measured the effects of neuromodulation in adults with PLP. Hedge's g effect size (ES) and 95% confidence intervals were calculated, and random-effects meta-analyses were performed.Fourteen studies (nine RCTs and five QE noncontrolled studies) were included. The meta-analysis of RCTs showed significant effects for i) excitatory primary motor cortex (M1) stimulation in reducing pain after stimulation (ES = -1.36, 95% confidence interval [CI] = -2.26 to -0.45); ii) anodal M1 transcranial direct current stimulation (tDCS) in lowering pain after stimulation (ES = -1.50, 95% CI = -2.05 to 0.95), and one-week follow-up (ES = -1.04, 95% CI = -1.64 to 0.45). The meta-analysis of noncontrolled QE studies demonstrated a high rate of pain reduction after stimulation with transcutaneous electrical nerve stimulation (rate = 67%, 95% CI = 60% to 73%) and at one-year follow-up with deep brain stimulation (rate = 73%, 95% CI = 63% to 82%).The evidence from RCTs suggests that excitatory M1 stimulation-specifically, anodal M1 tDCS-has a significant short-term effect in reducing pain scale scores in PLP. Various neuromodulation techniques appear to have a significant and positive impact on PLP, but due to the limited amount of data, it is not possible to draw more definite conclusions.

Case Report: Anti-LGI1 Limbic Encephalitis Associated With Anti-thyroid Autoantibodies

Frontiers in Neurology (2021)

Ricardo Otiniano‐Sifuentes Mireya A. Cuba Walter F. De La Cruz Ramirez Kevin Pacheco‐Barrios Darwin A. Segura Chavez

Anti-LGI1 encephalitis is an autoimmune encephalitis with antibodies against leucine-rich glioma-inactivated 1 (LGI1), first described in 2010. It is a non-frequent and poorly understood entity that represents the second most frequent cause of autoimmune encephalitis. This entity is characterized by the presence of limbic encephalitis, hyponatremia, and faciobrachial dystonic seizures. Herein, we present the case of a male patient with an onset of epileptic seizures (generalized tonic-clonic seizure), and involuntary dystonic movements that affect the right side of his face and right upper limb associated with mental disorder, and affectation of higher functions. The electroencephalogram showed continuous generalized slowing of the background activity. The brain magnetic resonance imaging showed signal hyperintensity at the level of both mesial temporal lobes and hippocampi and in the head of the right caudate nucleus. Anti-thyroglobulin antibodies were positive, and he was initially diagnosed as Hashimoto's encephalopathy (HE). However, the response to corticosteroids was not completed as it is usually observed in HE. For that, antibodies for autoimmune encephalitis were tested, and the anti-LGI1 antibodies were positive in serum and cerebrospinal fluid. HE is an important differential diagnosis to consider. Furthermore, the presence of Anti-thyroglobulin antibodies should not be taken as the definitive diagnostic criteria, since these antibodies could be associated with other autoimmune encephalopathies, which include in addition to anti-LGI1, anti-NMDA and anti-Caspr2.

Motor Cortex Reorganization in Limb Amputation: A Systematic Review of TMS Motor Mapping Studies

Frontiers in Neuroscience (2020)

Muhammed Enes Gunduz Camila Bonin Pinto Faddi G. Saleh Velez Dante Duarte Kevin Pacheco‐Barrios

Purpose: The purpose of this systematic review is to evaluate motor cortex reorganization in amputees as indexed by transcranial magnetic stimulation (TMS) cortical mapping and its relationship with phantom limb pain (PLP). Methods: Pubmed database were systematically searched. Three independent researchers screened the relevant articles, and the data of motor output maps, including the number of effective stimulation sites, center of gravity (CoG) shift, and their clinical correlations were extracted. We calculated a pooled CoG shift for motor cortex TMS mapping. Results: The search yielded 468 articles, 11 were included. Three studies performed correlation between the cortical changes and PLP intensity, and only one study compared cortical mapping changes between amputees with pain and without pain. Results showed (i) enlarged excitable area and a shift of CoG of neighboring areas toward the deafferented limb area; (ii) no correlation between motor cortex reorganization and level of pain and (iii) greater cortical reorganization in patients with PLP compared to amputation without pain. Conclusion: Our review supports the evidence for cortical reorganization in the affected hemisphere following an amputation. The motor cortex reorganization could be a potential clinical target for prevention and treatment response of PLP.

Clinical-epidemiological characteristics associated with discharge outcomes and seasonality among surviving patients with Guillain-Barré syndrome in a national third-level hospital, Lima, Peru

Arquivos de Neuro-Psiquiatria (2021)

Victor Velásquez‐Rimachi Angélica Verónica López-Saavedra Ethel Rodriguez-López Hillary Elguera-Huaman Kelly Meza

ABSTRACT Background: Guillain-Barré syndrome (GBS) is an autoimmune disease that affects the peripheral nervous system. Severe motor deficit (SMD), respiratory impairment, cranial nerve involvement and autonomic dysfunction are associated with a poor prognosis. Objective: To investigate the association between the clinical-epidemiological characteristics and the discharge results among Peruvian patients with GBS. Methods: We carried out a retrospective observational study on patients with GBS who survived until discharge. We used the Brighton Collaboration’s criteria and considered Hughes Severity Scale (HSS) scores greater than two to be SMD. We defined the discharge results as an improvement if the HSS score decreased by at least one point from admission to hospital discharge and defined hospital stay as prolonged if > 14 days. Results: We analyzed 92 patients, among whom 70.7% were male. Quadriparesis (81.1%) and hyporeflexia (86.8%) were the most characteristic manifestations. We observed that more than half of the cases were in summer and winter. Gastrointestinal infections were associated with a higher proportion of prolonged stays. The proportion of improvement was lower among patients who had an SMD at hospital admission. We confirmed these results through fitting in multivariate models. Conclusions: The prolonged stay was related to previous gastrointestinal infection, while a less improvement in SMD individuals at admission. Prospective multicenter surveillance systems are needed for monitoring GBS cases in low-income settings like Peru.

Using Home-based, Remotely Supervised, Transcranial Direct Current Stimulation for Phantom Limb Pain

Journal of Visualized Experiments (2024)

Kevin Pacheco‐Barrios Daniela Martínez-Magallanes Cristina Xicota Naqui Marianna Daibes Elly Pichardo

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that uses low-amplitude direct currents to alter cortical excitability. Previous trials have established the safety and tolerability of tDCS, and its potential to mitigate symptoms. However, the effects are cumulative, making it more difficult to have adherence to the treatment since frequent visits to the clinic or outpatient center are required. Moreover, the time needed for transportation to the center and the related expenses limit the accessibility of the treatment for many participants. Following guidelines for remotely supervised transcranial direct current stimulation (RS-tDCS) implementation, we propose a protocol designed for remotely supervised and home-based participation that uses specific devices and materials modified for patient use, with real-time monitoring by researchers through an encrypted video conferencing platform. We have developed detailed instructional materials and structured training procedures to allow for self- or proxy-administration while supervised remotely in real time. This protocol has a specific design to have a series of checkpoints during training and execution of the visit. This protocol is currently in use in a large pragmatic study of RS-tDCS for phantom limb pain (PLP). In this article, we will discuss the operational challenges of conducting a home-based RS-tDCS session and show methods to enhance its efficacy with supervised sessions.
