Purpose: The International Abstract(s) of Surgery (IAS) was a monthly supplement to Surgery, Gynecology & Obstetrics (SG&O, later Journal of the American College of Surgeons) from 1913-1994, approximately equal in size to the journal itself. It followed the example of the Zentralblatt für Chirurgie (ZblCh), which had been compiling abstracts of the current world surgical literature since 1874 (but in the German language). This article seeks to review the relationships of these surgical abstract journals in historical context., Methods: Citations in the IAS were systematically sampled for 1913-1990, and in the ZblCh and other American and German surgical publications for 1905-1940. Changes in the proportions of citations by language category were tabulated over time and related to concurrent international events and the publication histories of the sampled journals., Results: German-language citations were most frequent until the First World War, even in America. They subsequently became less frequent in America, but remained dominant in Germany. Articles in French or other languages were occasionally cited by Americans, but in German publications, they were cited as frequently as those in English. Contemporary observations from this time confirm that the American literature was being disregarded by most German surgeons. Since the Second World War, surgical publications have become predominantly English-language, even in Germany, and printed abstract compilations have become irrelevant., Conclusions: The history of the IAS and ZblCh reflects world events of the early twentieth century, the isolation and decline of German scientific leadership, the rise of American surgery, and the transition from a multilingual print-based era to one where scientific communication is primarily electronic and in English., (© 2022.

Background: Multifocal papillary thyroid carcinoma (MPTC) has been reported in literature in 18-87 % of cases. This paper aims to review controversies in the molecular pathogenesis, prognosis, and management of MPTC., Methods: A review of English-language literature focusing on MPTC was carried out, and analyzed in an evidence-based perspective. Results were discussed at the 2013 Workshop of the European Society of Endocrine Surgeons devoted to surgery of thyroid carcinoma., Results: Literature reports no prospective randomized studies; thus, a relatively low level of evidence may be achieved., Conclusions: MPTC could be the result of either true multicentricity or intrathyroidal metastasis from a single malignant focus. Radiation and familial nonmedullary thyroid carcinoma are conditions at risk of MPTC development. The prognostic importance of multifocal tumor growth in PTC remains controversial. Prognosis might be impaired in clinical MPTC but less or none in MPTC <1 cm. MPTC can be diagnosed preoperatively by FNAB and US, with low sensitivity for MPTC <1 cm. Total or near-total thyroidectomy is indicated to reduce the risk of local recurrence. Prophylactic central node dissection should be considered in patients with total tumor diameter >1 cm, or in cases with high number of cancer foci. Completion thyroidectomy might be necessary when MPTC is diagnosed after less than near-total thyroidectomy. Radioactive iodine ablation should be considered in selected patients with MPTC at increased risk of recurrence or metastatic spread.

The aim of this paper is to demonstrate an example of evidence-based medicine for a clinically relevant and frequent disease - gastro-oesophageal reflux disease - for which an increasing number of laparoscopic operations is performed. A consensus development conference was performed on this topic in 1996. During the following 3-year period, increase of knowledge shown by the number of publications was monitored and the consecutive changes of the consensus as well as its consequences and impact were analysed. The six published randomised clinical trials revealed important information about the technique of the laparoscopic operation focussing on the gastric fundic mobilisation and the modification of the anti-reflux wrap. Five consecutive consensus conferences were performed and published. Citations of the 1996 consensus conference could not be found in the major surgical journals - not even by participants of the conference. The responsibility of societies to run such conferences continues.
