Spatial and Ecological Factors Modulate the Incidence of Anti-NMDAR Encephalitis-A Systematic Review.

Anti-NMDAR encephalitis has been associated with multiple antigenic triggers (i.e., ovarian teratomas, prodromal viral infections) but whether geographic, climatic, and environmental factors might influence disease risk has not been explored yet.

Long-Term Follow-Up on Bilateral Posterior Hypothalamic Deep Brain Stimulation for Treating Refractory Aggressive Behavior in a Patient with Cri du Chat Syndrome: Analysis of Clinical Data, Intraoperative Microdialysis, and Imaging Connectomics.

Posterior hypothalamic-deep brain stimulation (pHyp-DBS) has been reported as a successful treatment for reducing refractory aggressive behaviors in patients with distinct primary diagnoses. Here, we report on a patient with cri du chat syndrome presenting severe self-injury and aggressive behaviors toward others, who was treated with pHyp-DBS. Positive results were observed at long-term follow-up in aggressive behavior and quality of life.

Accuracy of the Babinski sign in the identification of pyramidal tract dysfunction.

Background: The extensor plantar response described by Joseph Babinski (1896) indicates pyramidal tract dysfunction (PTD) but has significant inter-observer variability and inconsistent accuracy. The goal of this study was to determine the accuracy of the Babinski sign in subjects with verified PTD.

Methods: We studied 107 adult hospitalized and outpatient subjects evaluated by neurology.

Non-Hodgkin lymphomas of oral cavity.

Non-Hodgkin lymphomas (NHL) often show up in an extranodal pattern, especially in the head and neck. Intraoral locations are much less frequent, particularly when they are single. This, in turn, can lead to a prolonged diagnosis and even to inadequate treatment.

Oral surgery in patients undergoing oral anticoagulant therapy.

Unlabelled: There is an evident need for procedural protocol for oral surgery patients who undergo oral anticoagulant treatment (OAT) because of: 1) the possible severity of complications and 2) the growing demand for OAT, which in some cases may be as much as 8% of the oral surgery patients that are referred to the hospital from primary care centers. In this study, the authors define the parameters for creating a proto- col applicable to this group of patients. The conclusion is that it is not necessary to suspend OAT before surgery; rather, these procedures should be performed under multidisciplinary medical control.
