Arachnoid granulations: Dynamic nature and review.

Arachnoid granulations have been known for centuries yet remain incompletely understood. While traditionally associated with cerebrospinal fluid transport, the precise mechanism remains uncertain. This manuscript reviews the literature on the anatomy, histology, and imaging findings of arachnoid granulations and their mimickers and anomalous variations.

A Case Report of Antibiotic-Induced Aseptic Meningitis in Psoriasis.

Although frequently prescribed, certain antibiotics such as trimethoprim-sulfamethoxazole carry the risk of a rare yet life-threatening adverse effect, termed drug-induced aseptic meningitis. Morbidity can be avoided if the medication is identified and discontinued. Patients in reported cases tend to be female and have an autoimmune disease or prior adverse reaction to the offending agent.

Demographic and socioeconomic disparities of benign cerebral meningiomas in the United States.

Epidemiology provides an avenue for deciphering disease pathogenesis. By determining incidence across socioeconomic and demographic variables in the context of benign cerebral meningiomas (BCM), epidemiologic data may aid in elucidating and addressing healthcare inequalities. To investigate BCM incidence (per 100,000) with respect to sex, age, income, residence, and race/ethnicity, we queried the largest United States (US) administrative dataset (1997-2016), the National (Nationwide) Inpatient Sample (NIS), which surveys 20% of US discharges.

Idiopathic Intracranial Hypertension in the United States: Demographic and Socioeconomic Disparities.

Obesity's risk increases for low-income, female, young, and Black patients. By extrapolation, idiopathic intracranial hypertension (IIH)-a disease associated with body mass index-would potentially display socioeconomic and demographic disparities. IIH incidence (per 100,000) was investigated with respect to sex, age, income, residence, and race/ethnicity, by querying the largest United States (US) healthcare administrative dataset (1997-2016), the National (Nationwide) Inpatient Sample.

Variable Nitrogen Fixation in Wild Populus.

The microbiome of plants is diverse, and like that of animals, is important for overall health and nutrient acquisition. In legumes and actinorhizal plants, a portion of essential nitrogen (N) is obtained through symbiosis with nodule-inhabiting, N2-fixing microorganisms. However, a variety of non-nodulating plant species can also thrive in natural, low-N settings.
