Abstract

Insights

Multiple meningiomas, tumors in the brain lining, likely arise from varied origins, with estrogen potentially playing a role. Surgical removal of all tumors is feasible and recommended for better outcomes.

Area of Science:

  • Neuro-oncology
  • Pathology
  • Genetics

Context:

  • Multiple meningiomas are rare intracranial neoplasms.
  • Understanding their diverse origins and optimal management is crucial.

Purpose:

  • To investigate the genesis, classification, diagnosis, and treatment of multiple meningiomas.
  • To analyze treatment outcomes based on tumor classification.

Summary:

  • A retrospective study of 32 multiple meningioma cases was conducted, classifying them into five groups: primary, postoperative, neurofibromatosis-associated, meningiomatosis, and those with other intracranial tumors.
  • All patients underwent surgical resection, with 25 achieving a cure and 7 showing improvement.
  • Findings suggest varied cytogenesis and a potential role for estrogen in multiple meningioma development.

Impact:

  • This study advocates for single-stage resection of all tumors when feasible, acknowledging the tolerance for staged operations.
  • It highlights that treatment principles and prognosis differ across various multiple meningioma classifications.

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
