Evaluation of serum levels of interleukin-10, interleukin-11 and leukemia inhibitory factor in differentiation of eutopic and tubal ectopic pregnancies.

PURPOSE OF STUDY: To investigate whether serum levels of leukemia inhibitory factor (LIF), interleukin 10 (IL-10) and interleukin 11 (IL-11) are different in reference to the site of implantation. METHODS: Seventeen patients with laparoscopic diagnoses of tubal ectopic pregnancy (EP) and 19 patients with intrauterine pregnancy delivering healthy term neonates (IUP) were prospectively evaluated for LIF, IL-10 and IL-11 levels. The data were compared by using the Student's t-test, chi-square test, Kruskal-Wallis and the Mann-Whitney U test with Bonferroni's correction (p < 0.05) as appropriate. RESULTS: A statistically significant difference was observed in serum LIF levels between the EP and IUP groups (p = 0.002). Ranges of LIF were 15-300 and 70-1200 ng/ml for the IUP and EP groups, respectively. There were no significant differences between groups in terms of IL-10 and IL-11 levels. CONCLUSION: LIF, but not IL-10 or IL-11, levels may be increased in early tubal ectopic pregnancies when compared to normal intrauterine pregnancies.

An objective method to determinme corneal changes during menopause.

OBJECTIVE: We hypothesized that menopause has a measurable effect on corneal thickness. The aim of this study was to evaluate central corneal thickness (CCT) differences between women in the premenopausal and postmenopausal period. METHODS: A prospective, case-control, single-blind study was designed. Two groups were included: Group I (premenopausal period) and Group II (postmenopausal period). Forty women were recruited in each group. The correlation between CCT with age, estradiol (E2) and follicle stimulating hormone (FSH) levels were evaluated. RESULTS: CCT was significantly decreased in postmenopausal women compared to premenopausal women (521.18 +/- 37.97 microm 561 +/- 42.84 microm, respectively, p < 0.005). Similarly, there was a linear correlation between CCT and serum E2 levels of patients overall (p < 0.01). CONCLUSION: The data presented in this study suggest that menopause causes corneal changes, which may be documented by central corneal thickness measurement.

Tissue and plasma carcinoembryonic antigen concentration in gynecologic malignancies.

In this study tissue and plasma concentrations were established in eight patients with gynecologic malignancies, and correlations between tissue and plasma CEA concentrations were compared. Tissue concentration was determined by the immunoperoxidase staining method. Plasma CEA concentration was lower than tissue concentration. The causes of this difference were examined in this study.

Histopathologic correlation of dilatation and currettage and hysterectomy specimens in patients with postmenopausal bleeding.

PURPOSE OF INVESTIGATION: To evaluate the consistency of preoperative and postoperative histopathological findings in postmenopausal patients with abnormal bleeding. METHODS: Pathologic diagnoses of 42 postmenopausal women with abnormal bleeding or increased endometrial thickness who underwent both dilatation and curettage (D and C), and hysterectomy for proper indications were retrospectively examined. RESULTS: The most common diagnosis was irregular proliferative endometrium in both the pre- and postoperative groups with 16 patients each (38%). After subgroup analysis, 50% of the patients with a preoperative diagnosis of complex hyperplasia without atypia, had complex atypical hyperplasia, and two-thirds of the patients with a preoperative diagnosis of complex atypical hyperplasia had endometrial cancer as the final diagnoses. CONCLUSION: Preoperative D and C endometrial pathology findings positively correlated with postoperative hysterectomy pathology results. However, as the real pathology gets worse , D and C seems to under-diagnose the real pathology. In cases with complex hyperplasia with or without atypia , a second D and C or hysteroscopic evaluation may be recommended.

Differentiation of benign and malignant adnexal masses: value of a morphologic scoring system.

OBJECTIVE: The purpose of this study was to assess the value of conventional gray-scale ultrasonography, based on a morphologic scoring system, in the differential diagnosis of malignant and benign adnexal tumors. MATERIAL AND METHODS: A total of 58 adnexal masses in 51 patients were classified prospectively as suggestive of malignant or benign, on the basis of gray-scale ultrasonographic morphology. The results were correlated with histopathological diagnosis. RESULTS: Histopathology of 42 masses was found to be benign and 16 masses were found to be malignant. On gray-scale analysis 15 of 16 malignant masses were classified as suggestive of malignant and 37 of 42 benign masses were classified as suggestive of benign. The sensitivity, specificity, positive predictive value and negative predictive value are calculated as 93%, 88%, 75%, and 97%, respectively. CONCLUSION: Prediction of malignancy using gray scale ultrasonograhy based on a morphological scoring system was reliable (NPV = 97%, PPV = 93%). However further investigations about the assessment of adnexal masses with ultrasonography are needed

Watermelon as a New Host of Pseudomonas viridiflava, Causal Agent of Leaf and Stem Necrosis, Discovered in Turkey.

Severe leaf and stem necrosis symptoms were observed on watermelon seedlings (Citrullus lanatus cv. Euroca) in Adana, Turkey during a warm and humid period in January 2004. Streak-plate isolations were made from leaf and stem lesions on King's medium B. A fluorescent, yellowish mucoid, gram-negative, and oxidase-, levan- and arginin dihydrolase-negative bacterium was consistently isolated from diseased plant samples. All seven representative strains isolated were pectolytic on potato slices and hypersensitive reaction positive on tobacco leaves. The result of LOPAT tests and morphology of the strains were different from Pseudomonas syringae pathovars. The strains produced acid from sorbitol, fructose, glucose, L (+) arabinose, D (+) xylose, D (-) mannitol, but not from D (+) sucrose, trehalose, maltose, melibiose, lactose, and D (-) arabinose. Utilization of D (-) tartrate was positive. Incubation was at 28°C, and the results of the tests were evaluated 7 days after inoculation. Fatty acid analysis (Ataturk University, Erzurum, Turkey) confirmed the bacterial strains as P. viridiflava with a similarity index of 83 to 86% (3). The strains were pathogenic on watermelon, melon, and tomato plants with needle inoculation of bacterial suspensions containing 108CFU ml-1 in a 0.85% saline. Water-soaking and stem necrosis symptoms were observed on the inoculated plants 5 to 7 days after inoculation. The bacterium was readily reisolated from inoculated plants and identified as strains of P. viridiflava, which has been previously reported as a pathogen of melon grown in Turkey (1) and Greece (2). To our knowledge, this is the first study demonstrating the occurrence and outbreak of leaf and stem necrosis disease caused by P. viridiflava on watermelon in the world. References: (1) A.
