Glioblastoma (GBM) is the most aggressive, malignant, and drug-resistant brain tumor. There are no effective treatment options for GBM, which usually leads to relapses that cause patients to die a few months later. Ferroptosis, a newly discovered mechanism of regulated cell death, has been identified as a tumor suppressor in solid tumors and represents an alternative to apoptosis resistance.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare necrotizing vasculitis affecting small- to medium-sized vessels that can manifest in a multisystemic manner. While the classic triad of rhinosinusitis, asthma, and eosinophilia is commonly associated, it is essential to recognize that these features are not mandatory for diagnosis. We present a case of a 61-year-old woman with a unique EGPA manifestation who was hospitalized because of a seven-month history of weight loss, asthenia, epigastric abdominal pain, peripheral eosinophilia, and paresthesia in the left feet and hand.

Rosai-Dorfman Disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare non-Langerhans cell histiocytic neoplasm. Although the disease classically presents as massive painless lymphadenopathy in young adults, RDD can also involve the central nervous system in some patients. CNS lesions, can cause headaches, neurologic deficits, and even neurologic deficits.

Stereotactic frameless needle brain biopsy is a common neurosurgical procedure performed via twist drill or open burr hole approaches. We aim to compare diagnostic yields and surgical outcomes to delineate the safety and efficacy of both approaches. A retrospective database of all stereotactic needle biopsy procedures performed at a single institution over 30 months was conglomerated.

The fundamental idea underlying the use of amorphous solid dispersions (ASDs) is to make the most of the solubility advantage of the amorphous form of a drug. However, the drug stability becomes compromised due to the higher free energy and disorder of molecular packing in the amorphous phase, leading to crystallization. Polymers are used as a matrix to form a stable homogeneous amorphous system to overcome the stability concern.
