  • TREATMENT• Immune competent - Fuconazole,Itraconazole• Immune Deficient – Amphotericin B Flu cytosine AIDS patients are not totally cured, Relapses are frequent with fatal outcome. Rapid resistance with Fluconazole.[slideshare.net]
  • Nevertheless, we would not recommend decompressive laminectomy as first line treatment because of the individuality of our case.[jnnp.bmj.com]
  • It may also be that DNA is detected from fungal cells which are not viable and remained in liquor after treatment, since these samples were from patients who were under treatment.[mycology.imedpub.com]
