Unusual anatomic variation: The posterior inferior cerebellar artery arising from the middle meningeal artery.

An adult patient was admitted to our emergency department for a first episode of generalized tonic-clonic seizure. Computed tomography scan and magnetic resonance imaging showed a temporal intracranial hemorrhage and parenchymal edema caused by a dural arteriovenous fistula (DAVF), whose angioarchitecture was better understood through the DSA which showed as intriguing and rare vascular anomaly the origin of the posterior inferior cerebellar artery (PICA) from the middle meningeal artery (MMA). The endovascular treatment of the DAVF was then successfully performed.

A new species of Coelidiana Oman (Hemiptera: Cicadellidae: Neocoelidiinae) from Brazil with key to Brazilian species, description of immature stages, and notes about parasitoids and host plant.

Neocoelidiinae is a subfamily of Cicadellidae endemic to the American continent with 199 valid species allocated in 36 genera and two tribes. Coelidiana comprises 23 species distributed in Central and South America. Here we describe a new species for the genus: Coelidiana aroeira sp.

Pharsalus repandus Melichar, 1906 (Hemiptera, Ricaniidae): first record of ant-attendance in the family, ethological notes, and new records from Brazil.

Ant attendance or trophobiosis is widely distributed in Auchenorrhyncha and can be defined as a disjunctive association, an interspecific relationship between two symbiotic organisms. Aggregation behavior with or without ant mutualism has been documented for nymphs and adults in a few families of Fulgoromorpha whereas ant-attendance is reported for all planthopper families except for Ricaniidae. Based on field observations of Pharsalus repandus Melichar, 1906, the present work aims to record the first mutualistic interaction of ant-attendance in a species of the family Ricaniidae, report its aggregation behavior, its host plant, and expand its known distribution to the states of Paraná and Minas Gerais.

A Decades-Long Journey of Palmitoylethanolamide (PEA) for Chronic Neuropathic Pain Management: A Comprehensive Narrative Review.

Palmitoylethanolamide (PEA) has been prescribed in neuropathic pain management for over 20 years. This study aims to summarize what has been published on the topic in the last 15 years and determine the appropriateness of the prescribing. It describes the pharmacological aspect of PEA, especially focusing on its pharmacodynamics and pharmacokinetics.

SARS-CoV-2 in semen: a multicenter prospective study and literature review.

Background: Despite numerous efforts to demonstrate the presence of the SARS-CoV-2 in semen of affected males, no clear evidence exists. We conducted a multicenter prospective study on adult patients with a confirmed diagnosis of SARS-CoV-2 including patients with active infection (Active Group) and with a history of COVID-19 disease at least of 6 months (Recovered Group). An RT-PCR test for SARS-CoV-2 and a semen analysis were performed on the semen of the enrolled patients.
