    Background: Human papillomavirus (HPV), the causative agent of cervical cancer, is also suggested as a risk factor for gastric adenocarcinoma. Many infectious agents besides Helicobacter pylori have been associated with gastritis. The aim of this study was to investigate HPV DNA and genotyping HPV type 16 DNA in gastric adenocarcinoma and Helicobacter pylori gastritis cases. Methods: A hundred and six gastric adenocarcinoma and Helicobacter pylori gastritis samples and 26 controls were included. After deparaffinization by xylene, DNA extraction was performed by the phenol-chloroform-isoamyl alcohol method and 106 samples were studied with a G6PDH control kit (Eurogentec, Seraing, Belgium). Fifty-three adenocarcinoma and 43 Helicobacter pylori samples were thought to have enough tissue and were studied for HPV DNA. HPV types other than 16 and HPV type 16 DNA were detected by Real Time PCR using the L1 region. Amplifications of MY09/11 products were done by GP5+/GP6+ primers and Cyanine-5 labeled HPV DNA and HPV 16 DNA specific probe in Light Cycler 2.0 (Roche Diagnostics, Germany) device. Results: Among gastric adenocarcinoma and Helicobacter pylori gastritis samples, 20/53 (38%) and 18/43 (41.8%) were HPV DNA positive, respectively. Five (19.2%) of 26 controls were HPV DNA positive. Conclusions: Our 38% positive result in the gastric carcinoma group is in concordance with previous reports. This is the first study revealing the HPV-H. pylori relationship in gastritis cases and we concluded that with regard to the nearly three-fold higher HPV DNA (41.8%) in gastritis cases compared to controls, Helicobacter pylori positive cases should also be evaluated in favor of HPV in the gastritis group.

    Prostate Biopsy in the Elderly: Histologic Findings and Treatment Necessity
    (2014) Akman, Ramazan Yavuz; Koseoglu, Hikmet; Oguzulgen, Ahmet Ibrahim; Sen, Erhan; Yaycioglu, Ozgur; 25374232
    The aim of this study is to determine results of high prostate specific antigen (PSA) or abnormal digital rectal examination driven prostate biopsies performed in our Department in men aged 75 or more and to show the characteristics of pathology results. The hospital records of the patients who had high PSA or abnormal digital rectal examination driven prostate biopsy in two common university based research hospitals have been reviewed retrospectively. Patients aged 75 years or older at the date of biopsy whose records provided pathology results and full medical history were evaluated for the study. A total of 103 patients were evaluated with a mean age of 79.4 +/- 3.4 years. More than half of the patients (55.1%) were in their seventh decade and the rest were in the eighth decade. Median PSA value was 15.0 (range 2.1-4500) ng/ml. In most of the biopsies (67%), PSA levels were lower than 20 ng/ml. In almost half of the patients (48%), digital rectal examination was abnormal. In 68.9% of the patients, there were at least one or more associated co-morbid diseases. Gleason scores were 7 or higher in 73%, and 8 or higher in 37% of the patients with prostate cancer. Four of the 70 (6%) patients had bone metastases. Castrations were applied to most of the patients with prostate adenocarcinoma (% 79). High percentage of high grade (Gleason 7 or more) prostate adenocarcinoma in the elderly refutes the perception of prostate cancer in this age group as clinically insignificant. Therefore, it is to be kept in mind that prostate cancer in the elderly an be clinically significant and prostate biopsies are to be performed when necessary.
