Fatal Mucormycosis in a Diabetic Patient: A Case Report and Review of Diagnostic Challenges.

Mucormycosis (zygomycosis) is a severe and often fatal mycotic infection affecting primarily immunocompromised individuals. A 61-year-old female with type 2 diabetes mellitus and end-stage renal disease developed septic shock in association with mucormycosis. Despite antifungal treatment with liposomal amphotericin B, the patient's condition rapidly deteriorated, leading to death within 48 hours.

Changing Role of PET/CT in Cancer Care With a Focus on Radiotherapy.

Positron emission tomography (PET) integrated with computed tomography (CT) has brought revolutionary changes in improving cancer care (CC) for patients. These include improved detection of previously unrecognizable disease, ability to identify oligometastatic status enabling more aggressive treatment strategies when the disease burden is lower, its use in better defining treatment targets in radiotherapy (RT), ability to monitor treatment responses early and thus improve the ability for early interventions of non-responding tumors, and as a prognosticating tool as well as outcome predicting tool. PET/CT has enabled the emergence of new concepts such as radiobiotherapy (RBT), radioimmunotherapy, theranostics, and pharmaco-radiotherapy.
