Analysis of the usefulness of magnetic resonance imaging and clinical parameters in the detection of prostate cancer in the first systematic biopsy combined with targeted cognitive biopsy.

INTRODUCTION: The study aimed to assess the suitability of multiparametric magnetic resonance prostate imaging (mpMRI) in combination with clinical parameters [prostate-specific antigen (PSA), digital rectal examination (DRE)] in the identification of men at risk of the presence of prostate cancer (PCa) and clinically significant prostate cancer (csPCa, Gleason Score ≥3+4) in the cognitive fusion with systematic prostate biopsy. MATERIAL AND METHODS: We retrospectively evaluated a population of 215 biopsy - naive patients with a clinical suspicion of prostate cancer. The results of mpMRI, DRE, PSA and biopsy were analyzed. MpMRI of the prostate according to the Prostate Imaging Reporting and Data System (PI-RADS) v.2.0 scheme preceded cognitive fusion and systematic transrectal prostate biopsy. Uni- and multivariable logistic regression analysis (MVA) was used to identify the variables determining the risk of detecting PCa overall and csPCa. RESULTS: In MVA, it was established that the combination of variables such as PSA level [odds ratio (OR) 1.195; p = 0.002], PI-RADS ≥3 (OR 7.7; p = 0.002), prostate volume (OR 0.98; p = 0.017) significantly determines the probability of PCa detection in biopsy, while for csPCa it is PSA level (OR 1.14; p = 0.004), DRE (+) (OR 5.75; p <0.001), PI-RADS ≥4 (OR 6.5; p <0.001). Analysis of mpMRI diagnostic value for PI-RADS ≥4 revealed better sensitivity (88.9% vs 82.6%) and better negative predictive value (NPV) (94.5% vs 82.4%) for detection of csPCa than for PCa overall. CONCLUSIONS: MpMRI results combining with DRE and PSA parameters help to identify men at high - or low risk of csPCa detection in the first - time biopsy.

The association between tobacco intake, in different forms (smoking and smokeless tobacco), and frequency of urogenital disorders was analyzed. Based on wide bibliography the authors have concentrated especially on tobacco related urogenital neoplasm. Some types of neoplasm, like bladder carcinoma, were significantly tobacco dependent, others were not so clearly documented.

Two cases of pneumomediastinum were presented. Diagnosis was confirmed by plain chest X - ray and CT examination of the chest. None remarkable abnormality was found in a lung parenchyma or any other organs. Therefore the authors conclude that the direct cause of pneumomediastinum was psychostimulants administration--amphetamine. Typical treatment was successful.
