As the world faces a new viral pandemic, which has spread very rapidly, initial response from most countries was to suspend nonemergent health services so that available resources can be diverted to handle the large numbers of patients with COVID-19 infection. Many societies issued guidelines to suspend or postpone nonemergent surgeries.

We reviewed the emerging evidence regarding the impact of COVID-19 infection in neurosurgery and the postponement of elective surgeries.

COVID-19 infection poses serious threat in hospitals in the form of cross-infection, hospital staff falling sick, with potential risk to overwhelm or paralyze the healthcare. In addition, we have come to realize the significant perioperative morbidity and mortality secondary to active COVID-19 infection. All these strongly favor suspension of elective neurosurgical services. However, these have to be weighed against the fallout due to prolonged postponement of neurosurgical treatment for conditions, which can progress and cause neurological deterioration.

This article discusses the contemporary published literature regarding the perioperative risk of COVID-19 infection, impact of postponed surgeries, challenges, risk assessment and guidelines for elective neurosurgery at this point of time.

Low- and middle-income countries (LMICs) bear the majority of the neurosurgical burden of diseases but lack the resources to meet these needs.

As we increase access to neurosurgical care in LMICs, we must understand patient attitudes toward neurosurgery.

PubMed, LILACS, and African Journals Online databases were searched systematically from inception to January 4, 2020, for studies on neurosurgical patient perceptions in LMICs. The articles found were blindly reviewed with Rayyan by two authors. The two authors resolved conflicts between themselves, and when this was not possible, a third reviewer was consulted. All the articles included were then appraised, and the results were summarized.

Six of the 1,175 articles met the inclusion criteria. The studies were set in Brazil, Ethiopia, India, Nigeria, South Korea, and Sub-Saharan Africa. Four of the studies (50%) were phenomenological studies, and the other two were grounded theory and narrative. The studies identified patient attitudes toward neurosurgical practitioners, diseases, and interventions. Ethiopian and Nigerian patients believed cranial diseases to be otherworldly and resorted to traditional medicine or spiritual healing first, whereas Brazilian patients were more comfortable with cranial diseases and even more so if they had had a previous craniotomy. The Indian paper was a recount of a neurosurgeon's experience as a spine patient.

There are few studies on neurosurgery patient perception in LMICs. LMIC neurosurgeons should be encouraged to study their patient beliefs concerning neurosurgical diseases and interventions, as this can explain health-seeking behaviors.

M. Dastur in 1956. The department from its inception performed all diagnostic Neuro-Radiological procedures, angiography, ventriculography, pneumo-encephalography, and myelography. In 1976 transfemoral cerebral angiography was started by Dr S K Pandya. In 1978 he started performing interventional procedures. In 1980, Dr Anil Karapurkar went for training in Neuro-Intervention to Nancy, France, under Prof. Luc Picard. Thereafter all neurointerventions, cranial, and spinal, were performed routinely.Recent advances in technology, growing patient demand, and the need for social distancing due to Coronavirus Disease 2019 has expedited adoption of teledentistry in orthodontics as a means of consulting and monitoring a patient without an in-office visit. However, a lack of computer literacy and knowledge of software choices, and concerns regarding patient safety and potential infringement of regulations can make venturing into this new technology intimidating. In this article, various types of teledentistry systems for orthodontic practices, implementation guidelines, and important regulatory considerations on the use of teledentistry for orthodontic purposes are discussed. A thorough evaluation of the intended use of the software should precede commitment to a service. Selected service should be Health Insurance Portability and Accountability Act compliant at minimum and a Business Associate Agreement should be in place for protection of privacy. Ensuring the compatibility of the designated clinic computer with the system's requirements and installation of all safeguards must follow. Appointments should be documented in the same manner as in-office visits and teledentistry patients must be located within the clinician's statutory license boundary. Informed consent forms should include teledentistry or a supplemental teledentistry consent form should be used. Malpractice insurance covers everything usual and customary under the provider's license but the need for cyber liability insurance increases with teledentistry.

The aim of this study was to investigate the diagnostic accuracy of staging

F-FDG-PET/CT in laryngeal cancer, compare these results with conventional imaging (CI) and assess the value of

F-FDG-PET/CT features to predict survival.

Fifty-four patients with laryngeal squamous cell cancer and baseline

F-FDG-PET/CT were retrospectively enrolled. The PET images were analyzed visually and semi-quantitatively by measuring several metabolic parameters. Selleckchem Yoda1 A combination of clinical follow-up/imaging follow-up and/or histopathology was taken as reference standard. Progression free survival (PFS) and disease specific survival (DSS) were computed using Kaplan-Meier curves.

All primary tumors were clearly identified by CI, and 52/54 by

F-FDG-PET/CT with a sensitivity of 96.3%. Cervical nodal metastases were detected in 40/54 patients at

F-FDG-PET/CT and in 34/49 patients at CI. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy on a patient-based analysis for nodal disease were 100%, 85.
