A Case Of Retroperitoneal Fibrosis As A Confusing Reason Of Positive FDG/PET.

Retroperitoneal fibrosis is a rare disease and characterized by the presence of fibrous and inflammatory retroperitoneal tissue. Fluorine-18-fluorodeoxyglucose positron emission tomography (FDG/PET)is a beneficial methods for inflammatory dieseases. We presented here a case of 40 year old woman with idiopathic retroperitoenal fibrosis which detected high SUVmax level (21.4) on FDG/PET and had high erythrocyte sedimentatiton rate (140mm/h). If high SUVmax is detected, histologic confirmation is necessary to exclude malignancies.

Eosinophilic Fasciitis And Associated Late Emerging Hodgkin Lymphoma.

Abstracts: Eosinophilic fasciitis is often seen between the ages of 40-50, and is characterized with skin thickening, and etiopathogenesis is still unclear. Patients diagnosed as eosinophilic fasciitis have accompanying hematologic diseases in less than 10 %. In cases reported previously in the literature with a diagnosis of eosinophilic fascitis, accompanying hematological malignancies and solid organ malignancies were within the first 5 years after diagnosis. We here present, in this case 58 years old male who diagnosed hodgkin lymphoma after 21 years of eosinophilic fasciitis.

Serum neuron-specific enolase and S-100β levels as prognostic follow-up markers for oxygen administered carbon monoxide intoxication cases.

Serum neuron-specific enolase (NSE) and S-100β levels are considered novel biochemical markers of neuronal cell injury. In this study, the initial and post-treatment levels of NSE and S-100β were compared in carbon monoxide (CO) poisoning patients, who received normorbaric oxygen (NBO) or hyperbaric oxygen (HBO) therapy. Forty consecutive patients with acute CO poisoning were enrolled in this prospective, observational study. According to their clinical symptoms and observations, twenty patients were treated with NBO, and the other twenty with HBO. Serum S-100β and NSE levels were measured both at time of admission and 6 h later (post-treatment). Serum NSE and S-100β values decreased significantly in both of the therapeutic modalities. The initial and post-treatment values of NSE and S-100β in NBO or HBO patients were comparable. A clear negative correlation was observed between the decrease of NSE and S-100β levels and initial blood carboxyhemoglobin levels. In conclusion, the present results suggested the use of serum S-100β and NSE levels as indicators for brain injury. Due to the significant increase of their values with oxygen therapy, they may also be useful as prognostic follow-up markers. However, the current findings reflected no difference between the efficacy of NBO or HBO therapy.
