Despite the considerable amount of attention presently devoted to the high accessibility of online pornography, very little formal analyses have been carried out to show how the advent and proliferation of Internet technology has changed the prevalence of pornography use in populations. We conducted a preliminary analysis based on objective website traffic data, representing the changes in the number of (1) Internet users generally and (2) online pornography users specifically, between 2004 and 2016 in Poland. We observed a clear increase in the estimated number of people using online pornography in the analyzed period. The estimated number of general population members viewing pornography on the Internet increased over three times (310%) between October 2004 and October 2016–starting from an estimated 2.76 million in the first period to 8.54 million in the last. At the same time, we did not observe a clear increase in the percentage of Internet users who viewed online pornography in the same time period. Additionally, pornography viewership on the Internet was almost 2 times more prevalent among male (47%) than female Internet users (27%), and most popular in the 18–27 age group. Since our analysis is based on objective data, it does not share the limitations inherent in self-reports. However, our approach also has several important limitations (e.g., the analysis does not include online activity generated on mobile devices and under a private browsing mode); thus, the results should be interpreted with caution.
Renal carcinoma metastases to the gastrointestinal tract are seldom reported in medical literature. The study presented a case of a 76-year old female patient who underwent nephrectomy, due to T2N0M0 clear cell renal carcinoma and was additionally diagnosed with two metachronous metastases to the gall-bladder and pancreas. Abdominal ultrasound performed 32 months after nephrectomy demonstrated the presence of cholelithiasis and gall-bladder polyp. Laparoscopic cholecystectomy was performed. Clear cell renal carcinoma metastasis restricted to the gall-bladder mucosa was diagnosed on the basis of the histopathological examination. After surgery the patient remained under follow-up. In December, 2009 (47 months after nephrectomy) abdominal computer tomography (CT) revealed the presence of a tumor located in the tail of the pancreas. Distal pancreatic resection and splenectomy was performed. The histopathological examination confirmed the presence of clear cell renal carcinoma metastasis. The patient is in good general condition, under follow-up at the oncological outpatient Clinic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
