Effect of Size and Location of Unruptured Intracranial Aneurysms on Self-Reported Headache.

AIM: To describe the relationship between aneurysm size and location with the prevalence of headache at diagnosis and three- and six-month follow-up in a sample of patients with UIA. MATERIAL AND METHODS: In this cohort study, patients were diagnosed with UIAs by digital subtraction angiography (DSA). Follow-up visits occurred three and six months after the diagnosis. Headache presence was registered, and headache was further classified by phenotypes. After DSA, the recorded variables were aneurysm number, morphology, location, and size (diameter [W], neck [N], and dome-neck distance [H]). The aspect ratio (H/N) and the dome/neck ratio (W/N) were calculated. The outcome of this study was the self-reported headache status at follow-up. RESULTS: Data from 42 patients and 46 aneurysms were available; 81.0% of patients were women, with a mean age of 57.4±14.3 years. Headache was reported by 61.9% of the patients. The pain phenotype was tension-type in 38.1%, migraine in 11.9%, neuralgia in 2.4%, and unclassifiable in 9.5%. The median (min-max) measurements were W=5.05 (0.89-22.9); N=3.02 (0.52-17.9); H=5.08 (0.92-23.0); aspect ratio 1.59 (0.68-17.69) and W/N ratio 1.65 (0.62-16.92). Thirty-three patients (37 aneurysms) received treatment, 47.8% by surgical clipping and 32.6% by endovascular occlusion. In the treated patients, headaches had persisted in 14.3% until the first visit and in 9.5% until the second visit. There were no differences in any registered variables between patients with and without headaches at follow-up. CONCLUSION: In this study, data was found that support that headaches in patients with UIAs improve after treatment and that such improvement is probably unrelated to the size and shape of the UIAs.

Reconversion of neurosurgical practice in times of the SARS-CoV-2 pandemic: a narrative review of the literature and guideline implementation in a Mexican neurosurgical referral center.

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic has forced the modification of surgical practice worldwide. Medical centers have been adapted to provide an efficient arrangement of their economic and human resources. Although neurosurgeons are not in the first line of management and treatment of COVID-19 patients, they take care of patients with neurological pathology and potential severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Here, the authors describe their institutional actions against the pandemic and compare these actions with those in peer-reviewed publications. METHODS: The authors conducted a search using the MEDLINE, PubMed, and Google Scholar databases from the beginning of the pandemic until July 11, 2020, using the following terms: "Neurosurgery," "COVID-19/SARS-CoV-2," "reconversion/modification," "practice," "academy," and "teaching." Then, they created operational guidelines tailored for their institution to maximize resource efficiency and minimize risk for the healthcare personnel. RESULTS: According to the reviewed literature, the authors defined the following three changes that have had the greatest impact in neurosurgical practice during the COVID-19 pandemic: 1) changes in clinical practices; 2) changes in the medical care setting, including modifications of perioperative care; and 3) changes in the academic teaching methodology. CONCLUSIONS: The Instituto Nacional de Neurología y Neurocirugía "Manuel Velasco Suárez" is one of the major referral centers for treating highly complex neurosurgical pathologies in Mexico. Its clinical and neurosurgical practices have been modified with the implementation of specific interventions against the spread of COVID-19. These practical and simple actions are remarkably relevant in the context of the pandemic and can be adopted and suited by other healthcare centers according to their available resources to better prepare for the next event.

WhatsApp in Stroke Systems: Current Use and Regulatory Concerns.

Smartphone use is extremely common. Applications such as WhatsApp have billions of users and physicians are no exception. Stroke Medicine is a field where instant communication among fairly large groups is essential. In developing countries, economic limitations preclude the possibility of acquiring proper communication platforms. Thus, WhatsApp has been used as an organizational tool, for sharing clinical data, and for real time guidance of clinical care decisions. It has evolved into a cheap, accessible tool for telemedicine. Nevertheless, regulatory and privacy issues must be addressed. Some countries have implemented legislation to address this issue, while others lag behind. In this article, we present an overview on the different roles WhatsApp has acquired as a clinical tool in stroke systems and the potential privacy concerns of its use.
