Knowledge and use of pericranial nerve blocks in headache treatment in Mexico.

Background: In developed countries, most of the neurologists use pericranial nerve blocks to treat headache patients, nevertheless, the knowledge and use patterns of this technique in developing countries are unknown.

Objective: Evaluate the knowledge and use patterns of pericranial nerve blocks in headache treatment by Mexican neurologists.

Material And Methods: We did a cross-sectional study, 90 Mexican neurologists completed a 26-question survey including data about sociodemographics, knowledge and patterns of use of pericranial nerve blocks.

Impact of COVID-19 Pandemic Lockdown on Migraine Patients in Latin America.

The coronavirus (COVID-19) pandemic, confinement, fear, lifestyle changes, and worldwide health care impacted almost all diseases. Reports from countries outside Latin America revealed differences in migraine patients. In this study, we describe and compare the immediate changes in migraine symptoms associated with COVID-19 quarantine in patients from Argentina, Mexico, and Peru.

Development of a TaqMan qPCR assay for trypanosomatid multi-species detection and quantification in insects.

Background: Trypanosomatid parasites are widely distributed in nature and can have a monoxenous or dixenous life-cycle. These parasites thrive in a wide number of insect orders, some of which have an important economic and environmental value, such as bees. The objective of this study was to develop a robust and sensitive real-time quantitative PCR (qPCR) assay for detecting trypanosomatid parasites in any type of parasitized insect sample.

Comorbidity between hypothyroidism and headache disorders in a Mexican population.

Introduction: Headache and hypothyroidism are common comorbidities. This is a cross-sectional study of the prevalence of hypothyroidism in headache patients in the largest Mexican headache registry.

Patients And Methods: PREMECEF is an e-database for patients with headaches.

Risk of Severe Coronavirus Disease 2019 Infection in Kidney Transplant Recipients.

Background: Despite all efforts, the incidence of severe coronavirus disease 2019 (COVID-19) infection has been high in renal transplant recipients, as in other groups (eg, older adults, patients with comorbidities or immunosuppression). The detection of any possible predictor of gravity could improve the early approach in these patients.

Patients And Methods: We registered data from renal transplant recipients with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection in our area for a year (March 2020 to March 2021).

The poor insane Ophelia: reconsidering Ophelia syndrome.

Introduction: The association between memory loss and Hodgkin's lymphoma has been given the eponym of Ophelia syndrome, in memory of Shakespeare's character in The Tragedy of Hamlet, Prince of Denmark. Nevertheless, there are differences between the disease and the character.

Objective: To review the origins and uses of the eponym through an original article by pathologist Ian Carr, its relation to the character Ophelia, and the related autoantibodies.

Poor patient awareness and frequent misdiagnosis of migraine: findings from a large transcontinental cohort.

Background And Purpose: Although migraine is the second most disabling condition worldwide, there is poor awareness of it. The objective was to assess the awareness of migraine and previous diagnostic and therapeutic consultations and treatments in a large international population of migraineurs.

Methods: This was a multicentre study conducted in 12 headache centres in seven countries.

PPIENSENLo: A Novel Mnemonics in Spanish for Alarm Criteria in Secondary Headaches in Children.

We present the first mnemonic in Spanish, "PPIENSENLo," for alarm criteria in secondary headaches in children in order to facilitate their identification, diagnosis, and treatment. A search was performed across different electronic databases for a mnemonics that applied to clinical alarm criteria in secondary headaches in children. None were found in English or Spanish.

[Posttransplant regression of uremic tumoral calcinosis].

Uremic tumoral calcinosis is the massive calcium-phosphate deposits in periarticular tissues, usually around large joints. It has been described between 1-7% hemodialysis patients and although its etiopathogenesis is unknown, it is associated to severe hyperparathyroidism, elevation of the serum calcium-phosphorus product or hiperphosphataemia. We describe the case of tumoral calcinosis in the shoulder due to hiperphosphataemia and elevated calcium-phosphorus product, treated with low calcium intensive dialysis and fast relapse that disappears after renal transplantation.

Medical and surgical treatment in neurocysticercosis a magnetic resonance study of 161 cases.

In a prospective non-controlled study we have treated 161 consecutive cases of Active Neurocysticercosis (NCC) diagnosed by Magnetic Resonance (MR). Active NCC was classified in: (1) brain parenchymal cysts (85 cases); (2) ventricular cysts (24 cases); (3) subarachnoid cysts (46 cases); and (4) cysticercus racemose (6 cases). All patients had MR follow up 1 month after treatment.
