    Objective: To investigate the role of CD147 expression in uterine smooth muscle neoplasms, as a potential diagnostic and prognostic marker in patients with leiomyosarcoma (LMS). Study Design: We investigated CD147 protein expression in uterine smooth muscle tumor samples from patients diagnosed with leiomyoma (n = 22), atypical leiomyoma (BLM) (n = 5), smooth muscle tumor of uncertain malignant potential (STUMP) (n = 14), and LMS (n = 22). The intensity and extensity of immunohistochemical staining were compared to determine its potential role in differential diagnosis. Spearman's rank correlation tests were performed to determine the relationship between CD147 expression and prognostic clinical and pathological criteria in the patients with LMS. Results: CD147 was strongly expressed in 81.8% (n = 18) of the LMS tissue samples. In fact expression of CD147 in LMS tissues was significantly higher than that of the three other uterine smooth muscle tumor types (p = 0.000). However, high CD147 expression was found in only one BLM sample and one STUMP sample. Furthermore, CD147 percent expression positively correlated with Ki67 percent expression (r = 0.466, p<0.05) and mitotic index (r = 0.554, p<0.05), respectively. Conclusion: Our results suggest that immunohistochemistry may be a helpful tool in determining whether CD147 is a useful marker in the differential diagnosis of certain uterine smooth muscle tumors. CD147 may also have prognostic value for patients with LMS. Yet, in order to determine the extent of this potential marker's utility as a diagnostic and prognostic indicator, a larger randomized multicenter study must be performed. © 2014 Old City Publishing, Inc.

    The frequency and the type of different etiological factors in primary amenorrhea
    (Acta Medica Mediterranea, 2014) Agacayak E.; Icen M.S.; Tunc S.Y.; Siddik Evsen M.; Kalkanli S.; Basaranoglu S.
    Aim: Primary amenorrhea (PA) is defined as the absence of menarche by the age of 14 without the development of secondary sexual characteristics or lack of menstruation by the age of 16 despite the existence of normal growth with the appearance of secondary sexual characteristics. We carried out a retrospective study, with the purpose of establishing the frequency and the type of different etiological factors among patients with primary amenorrhea. Material and method: A total of 108 subjects, age ranged from 14 to 33 years were included in the study. A complete physical examination, blood tests for hormonal profile, pelvic ultrasonography and magnetic resonance imaging were performed to all patients. Besides, genotypic evaluations were also performed for the patients who got the indication. Results: Out of the 108 patients presenting with primary amenorrhea, 40 (37,0%) had gonadal dysgenesis, 25 (23,1%) had Mullerian agenesis and 14 (12,9%) patients had hypogonadotropic hypogonadism. The genotypic evaluation revealed that 77.5 % (n=31) of cases had normal chromosome composition whereas 22.5% (n=9) had chromosomal abnormalities. Conclusion: In conclusion, we have determined the 3 most common causes of primary amenorrhea are ovarian dysgenesis, Mullerian agenesis and hypogonadotropic hypogonadism; this data is compatible with the literature. Abnormalities in chromosomal analysis were determined in 22,5% of patients, which is also compatible with the literature. Determining etiology, in this large range of diseases may be confusing in clinical practice. During evaluation of patients with primary amenorrhea; these results should be kept in mind in order to establish an algorithm.
