A rare surgical complication of Crohn's diseases: free peritoneal perforation
No full textBACKGROUND: Free peritoneal perforation is a rare complication of Crohn's
disease.
METHODS: We evaluated the incidence of free peritoneal perforation among 208
patients with Crohn's disease surgically treated in the period 1992-2000.
RESULTS: Five patients (2.4%) suffered from free peritoneal perforation. In 1
patient free peritoneal perforation was the first symptom of Crohn's disease. In
3 cases the perforation was in the small bowel and in 2 in the large bowel. All
patients underwent surgery: all cases had a resection of the involved bowel and
in two cases an ileostomy was performed in order to prevent severe peritonitis.
We did not observed mortality or major complications.
CONCLUSIONS: Free peritoneal perforation is rare with about 100 cases reported in
literature. No correlation seems to exist with previous corticosteroid treatment.
The surgical treatment is mandatory. Simple suture should be avoided. The most
appropriate treatment, whenever it is feasible, is resection of the involved
bowel with immediate or, in case of severe sepsis, delayed anastomosis

No full textINTRODUCTION: Acute gastrointestinal bleeding is rare in Crohn's disease.
METHODS: We characterized the clinical features and course of such hemorrhage in
patients seen at our institution from 1992 to 2000.
RESULTS: Five patients had gastrointestinal bleeding during Crohn's disease. All
patients had a known Crohn's disease, with a mean duration of the disease of 6
years. The source of bleeding was identified in four patients (80%). Endoscopy
was, in all patients, the first diagnostic procedure. An Hartmann total colectomy
with closure of the rectal stump and ileostomy was performed in three patients,
while two patients with ileal massive bleeding were treated conservatively. One
patient had a recurrence of bleeding from the small bowel one week later but he
didn't required surgical treatment. One patient with pancolic Crohn's disease
died on 10th postoperative day because of multiorgan failure and septic
complications.
CONCLUSIONS: Gastrointestinal bleeding is rare in Crohn's disease, with a
predilection for site of involvement. The preoperative diagnosis of the site of
bleeding is not easy, and enteroscopy should be mandatory in such patients.
Surgery is required for half of cases and recurrent haemorrhage should be an
appropriate indication for surgery

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
