No full textPurposes of the study were to evaluate the correlation between intratumoral blood flow and stage, histologic grade, depth of myometrial invasion and lymph node metastasis in endometrial carcinoma and to assess if vascular/lymphatic spaces invasion is predictable by Doppler ultrasound. Fifty-three patients with endometrial carcinoma were enrolled before surgical treatment. Transvaginal Color Doppler Ultrasound was performed to detect the areas of increased vascularity (>/=3) and to record the lowest resistance index (RI) from the blood flow signals within the tumour. Formalin fixed, paraffin embedded pathology slides were reviewed by a senior pathologist to evaluate histologic grading, depth of myometrial invasion, presence of lymph node metastasis and vascular/lymphatic spaces invasion. The number of patients with positive lymph node metastasis was too small to perform any statistical evaluation. Significantly lower RI was noted in tumours of advanced stage (>FIGO Stage I), tumours with higher histologic grade (Grade 3) and with presence of vascular invasion. No correlation was found for myometrial invasion (>50%). A high number of vascular areas was positively correlated with all the prognostic signs. Assessment of tumour changes in vascularity using colour Doppler ultrasound provides useful information for the preoperative prediction regarding stage and histologic grade. The good correlation between Doppler ultrasound results and histological finding of vascular/lymphatic spaces invasion is another point in favour of routine colour Doppler studies in patients with endometrial carcinoma. We believe this technique is useful both for preoperative staging and that recording of tumour recurrence pattern may lead to early selection of those patients that need additional therapy
Concomitant abdominal and intrauterine pregnancy after in vitro fertilization in a woman with bilateral salpingectomy. A case report
No full textBACKGROUND: Abdominal pregnancy is a rare event, and the concomitant presence of
an intrauterine pregnancy is very exceptional.
CASE: A case of concomitant abdominal and intrauterine pregnancy following in
vitro fertilization and embryo transfer (IVF-ET) occurred in a woman with
bilateral salpingectomy. The abdominal pregnancy was successfully treated
surgically, with preservation of the intrauterine pregnancy.
CONCLUSION: A careful ultrasound examination should be performed on women who
have undergone IVF-ET, and the possibility of abdominal pregnancy should be kept
in mind in the differential diagnosis of acute abdomen
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
