In another study, clinical outcomes were compared for 213 patients undergoing surgery vs. 351 patients under watchful observation. Only 6% of the conservatively treated patients developed symptoms later, while among the surgically treated patients, 5.6% developed persistent morbid condition, and 9.4% developed surgery-related morbid condition.Observation is not recommended in tumors already causing symptoms. Furthermore, close follow-up with imaging is required with an observation strategy to rule out an enlarging tumor. Surgery
Meningiomata usually can be surgically resected (removed) and result in a permanent cure if the tumor is superficial on the dural surface and easily accessible. Transarterial embolization has become a standard preoperative procedure in the preoperative management. If invasion of the adjacent bone occurs, total removal is nearly impossible. It is rare for benign meningiomata to become malignant.The probability of a tumor recurring or growing after surgery may be estimated by comparing the tumors WHO (World Health Organization) grade and by the extent of surgery by the Simpson Criteria. Radiation therapy
Radiation therapy may include photon-beam or proton-beam treatment, or fractionated external beam radiation. Radiosurgery may be used in lieu of surgery in small tumors located away from critical structures. Fractionated external-beam radiation also can be used as primary treatment for tumors that are surgically unresectable or, for patients who are inoperable for medical reasons.Radiation therapy often is considered for WHO grade I meningiomata after subtotal (incomplete) tumor resections. The clinical decision to irradiate after a subtotal resection is somewhat controversial, as no class I randomized, controlled trials exist on the subject.
Plazomicin, sold under the brand name Zemdri, is an aminoglycoside antibiotic used to treat complicated urinary tract infections. As of 2019 it is recommended only for those in whom alternatives are not an option. It is given by injection into a vein.Common side effects include kidney problems, diarrhea, nausea, and blood pressure changes. Other severe side effects include hearing loss, Clostridium difficile-associated diarrhea, anaphylaxis, and muscle weakness. Use during pregnancy may harm the baby. Plazomicin works by decreasing the ability of bacteria to make protein.Plazomicin was approved for medical use in the United States in 2018. It is on the World Health Organizations List of Essential Medicines. Medical uses
Plazomicin is approved by the U.S. Food and Drug Administration (FDA) for adults with complicated urinary tract infections, including pyelonephritis, caused by Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, or Enterobacter cloacae, in patients who have limited or no alternative treatment options. Zemdri is an intravenous infusion, administered once daily. The FDA declined approval for treating bloodstream infections due to lack of demonstrated effectiveness. The lack of demonstrated effectiveness was not so much about the antibiotic itself being ineffective so much as the low enrollment rate for the study. Studies using mouse models however, showed a high survival rate.Plazomicin has been reported to demonstrate in vitro synergistic activity when combined with daptomycin or ceftobiprole versus methicillin-resistant Staphylococcus aureus, vancomycin-resistant S. aureus and against Pseudomonas aeruginosa when combined with cefepime, doripenem, imipenem or piperacillin/tazobactam. It also demonstrates potent in vitro activity versus carbapenem-resistant Acinetobacter baumannii.
