English, German, and French were ranked first to third, respectively. A comparison between TLCS and TGCS revealed that most
of the citations were related to other fields. A few citations were devoted to medical ethics which was not unexpected because of the limited number of documents (3035 documents). The general impact factor illustrated that the articles of this field had a high average citation, which indicated that there was a close relationship between the articles related to this field and the other fields. The most productive authors had a high local Inhibitors,research,lifescience,medical impact factor and according to their records, their local impact factor was higher than total local impact factor. All of the documents were published in 901 journals among which “Journal of Medical Ethics” had published 290 articles (9.55%) Inhibitors,research,lifescience,medical and it was ranked first.
The existence of different journals with different scopes indicates that medical ethics is an interdisciplinary subject and the researchers of other fields are interested in this specialized field. Articles Inhibitors,research,lifescience,medical of this field have an increasing CI-1033 supplier growth rate and the present study indicates greater participation of the science community in medical ethics publishing. However, the number of citations does not have a uniform growth rate. This could be due to the small size of this field and its association with other small fields. The global distribution of the papers and their language variations signify the global concerns for medical ethics. Moreover, linguistic, geographic, and publication type diversity of the published articles indicate a sustainable development in this field. Conflict of interest: None declared
Carcinoma of the gallbladder is more common in women and usually Inhibitors,research,lifescience,medical seen in patients older than 50 years of age. It is more common in the white population than the black and in western countries than the Mediterranean.1 The relation between gallstone and gallbladder
carcinoma remain controversial. Adenocarcinoma is Inhibitors,research,lifescience,medical the most common malignant neoplasm of the gallbladder.1 Although areas of squamous differentiation is seen in adenocarcinoma, pure primary squamous cell carcinoma is rarely reported and accounts for less than 1% of all gallbladder malignancies.1 The histogenesis of squamous cell carcinoma of the gallbladder PAK6 has not been well understood. Some researchers have stated that squamous cell carcinoma originates from pre-existing squamous metaplasia of the gallbladder epithelium, while others concluded that it originates from squamous differentiation of neoplastic cells of adenocarcinoma.1,2 We present a pure case of squamous cell carcinoma with some areas of squamous metaplasia in the vicinity of the invasive tumor. Therefore, the former theory is more compatible with this case. Another purpose of this case presentation was to emphasize on the vague clinical presentation of gallbladder carcinoma.
