Analyzing results of cervical sagittal parameters in patients operated with polyetheretherketone cages without plate.

Study Design: This was a retrospective longitudinal observational study.

Purpose: The purpose of this study was to analyze the results of cervical sagittal parameters on preoperative and postoperative lateral radiographs in anterior cervical discectomy and fusion (ACDF). ACDF is believed to change craniocervical parameters and thus cervical curvature using polyetheretherketone (PEEK) or titanium cages with or without self-locking as well as an anterior plate, the latter of which has not been shown to provide better clinical or radiological results.

Innovative perspectives in limbic surgery using deep brain stimulation.

Limbic surgery is one of the most attractive and retaken fields of functional neurosurgery in the last two decades. Psychiatric surgery emerged from the incipient work of Moniz and Lima lesioning the prefrontal cortex in agitated patients. Since the onset of stereotactic and functional neurosurgery with Spiegel and Wycis, the treatment of mental diseases gave attention to refractory illnesses mainly with the use of thalamotomies.

The Inflammatory Biomarkers Behavior Profile of Patients Following Elective Degenerative Spine Surgery and Differences Compared to Those Coursing With a Postoperative Spinal Infection: Protocol for a Systematic Review.

Background: The incidence of postoperative spinal infection (PSI) ranges from 0% to 10%, with devastating effects on the patient prognosis because of higher morbidity while increasing costs to the health care system. PSIs are elusive and difficult to diagnose, especially in the early postoperative state, because of confusing clinical symptoms, rise in serum biomarkers, or imaging studies. Current research on diagnosis has focused on serum biomarkers; nevertheless, most series rely on retrospective cohorts where biomarkers are studied individually and at different time points.

Prognostic factors of unilateral prelemniscal radiations radiofrequency lesions: A surgical technique for the treatment of Parkinson's disease motor symptoms.

Objective: A group of patients with Parkinson's disease (PD) were managed with unilateral prelemniscal radiation radiofrequency lesions (U-Raprl). The current study aims to evaluate prognostic factors that could influence clinical response.

Methods: Patients previously diagnosed with PD managed with U-Raprl were included in the study, classifying them into two groups according to their percentage of clinical response ( View Article and Find Full Text PDF

Correlation of Biomarkers of Endothelial Injury and Inflammation to Outcome in Hospitalized COVID-19 Patients.

COVID-19 can trigger an intense systemic inflammation and prothrombotic state, leading to a rapid and disproportionate deterioration of lung function. An effective screening tool is essential to identify the patients at risk for severe disease. This observational study was conducted on hospitalized patients with moderate and severe COVID-19 pneumonia in a general hospital in Mexico City between 1 March 2021 and 15 March 2021.

Incobotulinum toxin type A for treatment of chronic myofascial pain.

Purpose: This study assessed the effectiveness of incobotulinum toxin type A (IBTx) for chronic myofascial pain affecting the masseter and temporal muscles.

Methods: Twenty two patients who received a diagnosis of chronic masseter and temporalis myofascial pain were evaluated by using a visual analog pain scale (VAS), digital pressure algometry, and the SF-36 Health Survey at baseline (T0), before IBTx injection. Patients were again evaluated at 2 months (T1) and 7 months (T2) after IBTx injection.

Effect of unilateral amygdalotomy and hypothalamotomy in patients with refractory aggressiveness.

Background: Neurosurgical treatment, although controversial, is considered a useful resource in the treatment of chronic psychiatric diseases such as refractory aggressiveness.

Objective: To evaluate the clinical results and side effects of posteromedial hypothalamotomy associated with amygdalotomy in patients with refractory aggressiveness.

Method: A clinical trial was conducted in patients with chronic aggressiveness and refractory to pharmacological treatment.

Validation of the Comic Strip Test to evaluate empathy in a Mexican population sample.

Introduction: Empathy is the ability of an individual to understand it from another cognitive and emotional point of view. Empathy is a complex that represents a retouch in its evaluation, so, it is necessary to have instruments validated in the Mexican population.

Objective: Validation of the Comic Strip Test to evaluate empathy.

[Efecto de la amigdalotomía e hipotalamotomía unilateral en pacientes con agresividad refractaria].

Background: Neurosurgical treatment, although controversial, is considered a useful resource in the treatment of chronic psychiatric diseases such as refractory aggressiveness.

Objective: To evaluate the clinical results and side effects of posteromedial hypothalamotomy associated with amygdalotomy in patients with refractory aggressiveness.

Method: A clinical trial was conducted in patients with chronic aggressiveness and refractory to pharmacological treatment.

[Validación de la prueba de Tiras cómicas para evaluar la empatía en una muestra de población mexicana].

Introduction: Empathy is the ability of an individual to understand it from another cognitive and emotional point of view. Empathy is a complex that represents a retouch in its evaluation, so, it is necessary to have instruments validated in the Mexican population.

Objective: Validation of the Comic Strip Test to evaluate empathy.

Primary Prophylaxis to Prevent the Development of Hepatic Encephalopathy in Cirrhotic Patients with Acute Variceal Bleeding.

Background And Aim: Variceal bleeding is the second most important precipitating factor related to the development of episodic hepatic encephalopathy; but to date there are no recommendations to prevent this complication. The aim of this study was to compare if primary prophylaxis with lactulose or L-ornithine L-aspartate or rifaximin, in cirrhotic patients with variceal bleeding, is better than placebo for avoiding the development of hepatic encephalopathy.

Methods: A randomized, double-blind, placebo-controlled clinical trial (ClinicalTrials.

Deep Brain Stimulation for Obsessive-Compulsive Disorder: A Meta-Analysis of Treatment Outcome and Predictors of Response.

Background: Deep brain stimulation (DBS) has been proposed as an alternative to ablative neurosurgery for severe treatment-resistant Obsessive-Compulsive Disorder (OCD), although with partially discrepant results probably related to differences in anatomical targetting and stimulation conditions. We sought to determine the efficacy and tolerability of DBS in OCD and the existence of clinical predictors of response using meta-analysis.

Methods: We searched the literature on DBS for OCD from 1999 through January 2014 using PubMed/MEDLINE and PsycINFO.

[Effect of metformin addition to an acute lymphoblastic leukemia chemotherapy treatment].

Background: Recently it has been reported a benefit effect with the use of metformin in patients with malignant disease. Our objective was to evaluate the effect of adding metformin to chemotherapy regimen over the percentage of early relapse in acute lymphoblastic leukemia.

Methods: A prospective, longitudinal and experimental study was performed in patients with de novo acute lymphoblastic leukemia enrolled in the Hospital General de México.

[Effect of posteroventral pallidotomy on event-related P300 in Parkinson's disease].

Background: Ablative procedures are still frequent for the surgical treatment of Parkinson's disease (PD). Although the P300 component has been used to assess cognitive changes induced by levodopa and deep brain stimulation (DBS), the effects caused by unilateral pallidotomy remain unknown.

Material And Methods: P300 amplitude and latency in 10 PD patients who underwent unilateral pallidotomy with and without levodopa treatment were compared with 10 healthy controls.

Evaluation of bilateral cingulotomy and anterior capsulotomy for the treatment of aggressive behavior.

Background: Agressiveness is a psychiatric symptom that may be part of schizophrenia, mental retardation, drug abuse and other conditions. Surgical treatment remains controversial and few therapeutic options are available. We undertook this study to perform a prospective analysis on the efficacy and safety of bilateral cingulotomy and anterior capsulotomy in the treatment of aggressiveness behavior.
