What's the bug?: An unusual cause of bacterial meningitis in a patient with history of transsphenoidal surgery.

Bacterial meningitis is an increasingly rare disease that carries significant morbidity and mortality. We describe the case of a 38-year-old male with a past medical history of pituitary macroadenoma with prior endonasal surgeries on prednisone therapy daily for resultant hypopituitarism and juvenile myoclonic epilepsy on lamotrigine daily who was transferred to an academic tertiary emergency department due to concern for developing pituitary apoplexy. At the outside emergency department, the patient presented complaining of sudden onset severe headache.

An understanding of intracellular mechanisms by which fentanyl and other synthetic opioids exert adverse effects on breathing is needed. Using freely moving adult male guinea pigs, we administered the nitric oxide synthase (NOS) inhibitor, L-NAME (N-nitro-L-arginine methyl ester), to determine whether nitrosyl factors, such as nitric oxide and S-nitrosothiols, play a role in fentanyl-induced respiratory depression. Ventilatory parameters were recorded by whole body plethysmography to determine the effects of fentanyl (75 μg/kg, IV) in guinea pigs that had received a prior injection of vehicle (saline), L-NAME or the inactive D-isomer, D-NAME (both at 50 μmol/kg, IV), 15 min beforehand.

Introduction And Importance: Myiasis is an overlooked public health issue, with urogenital myiasis (UGM) being particularly rare, as evidenced by only 59 reported cases worldwide from 1975 to 2017. There is a notable scarcity of cases involving patients with prolonged catheter use related to SCI. The interaction of SCI with the complications associated with indwelling urinary devices is less frequently discussed in prior literature.

Agricultural land classification plays a pivotal role in food security and ecological sustainability, yet achieving accurate large-scale mapping remains challenging. This study presents methodological innovations through a multi-level feature enhancement framework that transcends traditional time series analysis. Using Shandong Province, northern China's agricultural heartland, as a case study, we first established a foundation with time series red-edge vegetation indices (REVI) from Sentinel-2 imagery, uniquely combining the normalized difference red edge index (NDRE) and plant senescence reflectance index (PSRI).

Biological invasions occur when organisms are moved from their native range and introduced into new areas, where they can spread and become a potential risk for native organisms. Invasive species are well recorded for vertebrates, plants and a number of invertebrates. A taxa for which there is a lack of information in some countries are arachnids, and this is the case of reports on introduced species in Panama.
