RESUMO

In this paper, Allium sphaeronixum, a new species of the sect. Codonoprasum from Turkey, is described and illustrated. The new species is endemic to Central Anatolia, limited to the area of Nevsehir, where it grows on sandy or rocky soil at an elevation of 1000-1300 m a.s.l. Its morphology, phenology, karyology, leaf anatomy, seed testa micromorphology, chorology, and conservation status are examined in detail. The taxonomic relationships with the closest allied species, A. staticiforme and A. myrianthum, are also highlighted and discussed.

RESUMO

BACKGROUD: Twelve taxa of herbaceous Paeonia species were recorded in Türkiye. All definitions were performed morphologically and/or anatomically and there is no study based on DNA barcode sequences. Three barcode regions were sequenced to determine the phylogenetic relationships of Turkish Paeonia taxa. The chemical comparison of roots was also investigated. METHODS AND RESULTS: The taxons were collected between May and June 2021 from nine cities. Leaf materials were used for DNA isolation and ITS, matK and rbcL regions were amplified and sequenced. There was no difference among taxa in terms of rbcL sequences. But the ITS and matK regions distinguished 12 taxa and structured them in two groups. ITS region distinguished P. peregrina, P. arietina, and P. tenuifolia from other taxa, while matK region distinguished P. arietina and P. witmanniana from other taxa. Both barcode sequences actually showed that the registration of P. mascula subsp. arasicola was actually 100% similar to P. arietina. ITS was the most polymorphic region (n = 54) followed by matK (n = 9). These sequences could successfully discriminate Paoenia species from each other and diploid P. tenuifolia. The methanolic root (100 gr) extracts were examined for total phenolic and flavonoid content, and antioxidant activities. Significant variation was found for polyphenolic content, and antioxidant properties (TPC from 204.23 to 2343.89 mg, TFC from 7.73 to 66.16 mg, and FRAP from 523.81 to 4338.62 mg). SC50 values of ABTS and DPPH were ranged from 115.08 to 1115.52 µg/ml and 73.83 to 963.59 µg/ml, respectively. CONCLUSION: It was concluded that 11 of 12 taxa had differences in terms of ITS and matK sequences and these region must be used for the correct identification of Turkish Paeonia.

RESUMO

OBJECTIVES: To investigate the role of anti-human heat shock protein 60 (hHsp60) antibody positivity in the pathogenesis of ectopic pregnancy, following Chlamydia trachomatis (CT) infection. STUDY DESIGN: In a case-control study, serological tests for anti-hHsp60 were performed in ectopic pregnancies (study group) and parturients with normal reproductive histories (control group). All participants in both groups were CT IgG(+). hHsp60 IgG(+) prevalences were compared between the two groups, by semiquantitative ELISA. Data were evaluated using nonparametric and parametric tests and multivariable regression. RESULTS: After an initial pilot study, two groups were formed: 63 ectopic gestations (study group) and 95 normal parturients (control group), all CT IgG(+). Blood samples from all cases were tested for anti-hHsp60 IgG. Age, gravidity, and practising contraception were higher in the control group, while a history of pelvic infections were more common in the study group. Hsp60 IgG(+) was found to be significantly higher in the control group (63/95, 66.3%) compared to study group (30/63, 47.6%). Regression analysis revealed anti-hHsp60 positivity was an independent factor delineating the two groups. CONCLUSION: Immunity to hHsp60 is less common in CT IgG(+) ectopic pregnancies than CT IgG(+) fertile subjects without a history of ectopic pregnancies. Hence, our findings suggest that hHsp60 seropositivity may decrease the probability of an ectopic gestation in subjects with previous CT infections.

RESUMO

OBJECTIVES: To assess the safety and efficacy of electrosurgical bipolar vessel sealing during vaginal hysterectomy in morbidly obese patients MATERIAL AND METHODS: A total of 105 morbidly obese patients who underwent vaginal hysterectomy due to benign gynecologic pathologies between January 2010 and April 2017 were included in the study. Patients were divided into two groups according to whether conventional suture ligation technique (n = 64) or electrosurgical bipolar vessel sealing (n = 41) were used during vaginal hysterectomy. The surgical procedure was performed with the same technique in both study groups. The primary outcomes were duration of surgery and estimated blood loss. The secondary outcomes were intra-operative complications and post-operative complications. RESULTS: The duration of surgery and estimated blood loss in the vessel sealing group was significantly less than in the conventional suture group (p < 0.05). No significant difference was present between the two groups in the rate of intra-operative and post-operative complications. CONCLUSIONS: The primary outcome of our study is that the EBVS system can be used equally and even more effectively in some aspects; and as safe an alternative approach to conventional suture ligation technique during vaginal hysterectomies performed specifically on morbidly obese patients with reduced operation times and blood loss, and without increasing the complication rates.

RESUMO

OBJECTIVES: This study identified patients who would benefit from an earlier additional medical intervention and/or continuing close surveillance even if commonly used parameters indicated sufficient medical treatment to determine markers of treatment failure. MATERIALS AND METHODS: A retrospective analysis of patients with a preliminary diagnosis of ectopic pregnancy treated with the single-dose methotrexate protocol. Group 1: cases cured with a single dose of methotrexate; Group 2: cases who required more than one dose of methotrexate or surgery following the first dose. Demographics, clinical/sonographic findings, observation period, and ß-human chorionic gonadotropin (hCG) levels were compared among the two groups. Thresholds were defined and a regression analysis was performed to define independent predictors of failure. RESULTS: Data from 120 patients were analyzed: Group 1 (n = 92); Group 2 (n = 28). ß-hCG levels measured at all time points, and day (0-4) and day (4-7) changes, presence of adnexial masses, and infertility were significantly different among the two groups. Only the day (0-4) and day (4-7) changes in ß-hCG levels were independent predictors of failure. CONCLUSION: Day (0-4) thresholds or newly defined day (4-7) thresholds were not more sensitive than the conventional day (4-7) criteria. Day (0-4) ß-hCG levels increased by more than 9.7% in half the patients who required additional methotrexate doses or surgery despite fulfillment of the conventional day (4-7) criteria. In contrast, no cases of treatment failure were observed if the day (0-4) decrease was >26.6%.

RESUMO

OBJECTIVES: To determine if appendectomy as an adjunctive procedure is necessary in the surgical treatment of benign ovarian mucinous cystadenomas. MATERIAL AND METHODS: Retrospective analysis of clinical data: in a research hospital, obstetrics and gynecology depart-ment setting, 63 cases of benign ovarian mucinous cystadenomas confirmed in the pathological evaluation were revised. 59 had the complete clinical, final pathological and follow-up data available and were included. RESULTS: 20.6% (13/59) went through an appendectomy. Basic characteristics of patients with different appendiceal pathologies did not show any significant differences. In the study group the mean age, parity, adnexial mass size were (40.1 ± 12.4); (1.3 ± 1.1) and (9.1 ± 5.3 cm), respectively. Patients were either operated laparoscopically (20), laparotomically (39) to perform a unilateral salpingoopherectomy/cystectomy. In 7 patients, oopherectomy was an additional procedure with: 2 abdominal hysterectomies, 4 cesarean sections and 1 total laparoscopic hysterectomy. 2 synchronous appendiceal pathologies (mucinous cystadenomas of the appendix) were defined in appendectomies performed. In these cases, the ovarian tumour sizes were: 7 cm and 4 cm. CONCLUSIONS: In the presence of a benign or borderline unilateral ovarian mucinous tumour as defined during the operation and especially if it is larger than 10-12 cm and with normal peritoneal and appendiceal gross morphology, appendectomy is not a necessary adjunctive procedure.

RESUMO

OBJECTIVE: We investigated the effects of delayed and early clamping of the cord on the hematologic status of the baby at birth and at the end of second month. METHODS: Umbilical cord of 74 babies were clamped in the first 30 s (Group 1) and 76 were clamped at 90-120 s (Group 2). Levels of hemoglobin, hematocrit, iron and ferritin were analyzed from the umbilical cord blood at birth and from the venous samples at the end of second month. RESULTS: Hemoglobin, hematocrit, iron and ferritin levels of cord blood were similar in both groups. However, their levels other than ferritin were higher in Group 2 at the end of second month. Two babies had respiratory distress and twelve neonates received phototherapy in Group 2 whereas only five neonates received phototherapy in Group 1. CONCLUSION: Term babies to whom delayed cord clamping was performed had improved hematological parameters at the end of second month. Therefore, delaying cord clamping in these babies may be a favorible approach in preventing anemia.

RESUMO

OBJECTIVES: The objective of the study was to evaluate the association of maternal plasma levels of 25-hydroxyvitamin D (25(OH)D) at late second and third trimester and the risk of pre-eclampsia. METHODS: In this prospective cohort study, maternal plasma 25(OH)D levels were measured at late second and third trimester in 77 women who later developed pre-eclampsia (31 non-severe and 46 severe cases) and 180 women without pre-eclampsia. RESULTS: The mean gestational age of the timing of the blood sampling was 31.1 ± 4.4 at control group, 32.6 ± 5.7 at non-severe pre-eclamptic group and 32.3 ± 5.4 at severe pre-eclamptic group. The mean 25(OH)D concentration was significantly low in severe pre-eclampsia group (5.8 ± 4.5 ng/ml) than non-severe pre-eclampsia (11.8 ± 7.3 ng/ml, p = 0.039) and control groups (14.9 ± 12.0 ng/ml, p < 0.0001). There was no statistically significant difference in 25(OH)D concentration between non-severe pre-eclamptic and control groups (p = 0.404). In women with 25(OH)D concentration <20 ng/ml, a 12.45-fold increase in the odds of severe pre-eclampsia were detected. CONCLUSION: Women with severe pre-eclampsia had low serum 25(OH)D levels. The correlation between maternal 25(OH)D levels and aspartate aminotransferase, alanine transaminase, serum creatinine levels, platelet count were not determined. 25(OH)D levels may be used as an independent predictive marker of severe pre-eclampsia.

RESUMO

BACKGROUND: Two-dimensional (2D) view is known to cause practical difficulties for surgeons in conventional laparoscopy. Our goal was to evaluate whether the new-generation, Three-Dimensional Laparoscopic Vision System (3D LVS) provides greater benefit in terms of execution time and error number during the performance of surgical tasks. METHODS: This study tests the hypothesis that the use of the new generation 3D LVS can significantly improve technical ability on complex laparoscopic tasks in an experimental model. Twenty-four participants (8 experienced, 8 minimally experienced, and 8 inexperienced) were evaluated for 10 different tasks in terms of total execution time and error number. The 4-point lickert scale was used for subjective assessment of the two imaging modalities. RESULTS: All tasks were completed by all participants. Statistically significant difference was determined between 3D and 2D systems in the tasks of bead transfer and drop, suturing, and pick-and-place in the inexperienced group; in the task of passing through two circles with the needle in the minimally experienced group; and in the tasks of bead transfer and drop, suturing and passing through two circles with the needle in the experienced group. Three-dimensional imaging was preferred over 2D in 6 of the 10 subjective criteria questions on 4-point lickert scale. CONCLUSIONS: The majority of the tasks were completed in a shorter time using 3D LVS compared to 2D LVS. The subjective Likert-scale ratings from each group also demonstrated a clear preference for 3D LVS. New 3D LVS has the potential to improve the learning curve, and reduce the operating time and error rate during the performances of laparoscopic surgeons. Our results suggest that the new-generation 3D HD LVS will be helpful for surgeons in laparoscopy (Clinical Trial ID: NCT01799577, Protocol ID: BEHGynobs-4).

RESUMO

OBJECTIVE: We assess follicular reserve changes by follicle count in torsion-detorsion rat model. STUDY DESIGN: 30 albino rats were randomly divided into 3 groups: sham group (SG), detorsion after 24-hour torsion group (24hTG) and detorsion after 72-hour torsion group (72hTG). Ovaries were torsioned and fixed. They were untwisted 24 and 72 h later. Oophorectomies were performed at 14th day after detorsion. Tissue damage scoring and follicle counts were evaluated microscopically. RESULTS: Tissue damage scores (TDSs) were higher in 72hTG and 24hTG compared to SG. In addition, as we increase torsion duration, TDSs also increased. There was no statistically significant difference in follicle numbers (primordial, primary, secondary and tertiary). CONCLUSION: Duration of torsion and intensity of ovarian damage do not affect follicular reserve in a rat model. Regardless of their macroscopic appearance, ovaries maintain their follicle reserves after torsion. Thus, surgeons should be reassured and encouraged to untwist torsioned ovaries rather than removing them.

RESUMO

OBJECTIVE: To determine whether the measurement of beta-human chorionic gonadotropin (ß-hCG) levels in vaginal fluid is useful for the diagnosis of premature rupture of membranes (PROM). MATERIAL AND METHODS: A total of 92 pregnant women between 24 and 40 weeks gestation participated in this study. The patients with fluid leaking from the vagina were designated Group 1, the patients with no fluid leaking from the vagina were Group 2, and those with a suspicion of fluid leaking from the vagina were classified as Group 3. Irrigating the posterior vaginal fornix with 5 mL sterile saline was used to measure ß-hCG levels of the patients. Receiver operator curve (ROC) analysis was used to determine the cut-off value for a positive diagnosis. RESULTS: The ß-hCG levels of vaginal fluid were measured as 20.5±25.0 mIU/mL, 254.6±346.8 mIU/mL, and 74.3±100.8 mIU/mL in Group 1, Group 2, and Group 3, respectively. Vaginal ß-hCG level was higher statistically significantly in Group 2 than Group 1 and 3 (p<0.001). 100 mIU/mL was accepted as a cut-off value by using the receiver operating characteristic curve. According to 100 mIU/mL, sensitivity, specificity, positive predictive and negative predictive values were calculated as 71.2, 100, 100, and 65.1%, respectively. CONCLUSION: The study showed that the measurement of ß-hCG level in vaginal washing fluid is an efficient and easy diagnostic test for predicting the amount of fluid leaking from the vagina. However, due to the low negative predictive value of the test, it would not be convenient in daily practice.

RESUMO

OBJECTIVE: To compare the efficacy of fosfomycin trometamol, cefuroxime axetil, and amoxicillin clavulanate antibiotics, and to assess the difference in patient compliance, in the treatment of urinary tract infections during pregnancy. METHODS: Between September 2007 and May 2008, 90 out of 324 pregnant women with complaints of lower urinary tract infection, who were followed at the outpatient clinic or referred to the emergency department of Vakif Gureba Education and Research Hospital, were enrolled in a prospective study. Patients were randomized into 3 equal groups for treatment with single-dose fosfomycin trometamol, or 5-day courses of amoxicillin clavulanate or cefuroxime axetil. After follow-up, study data were obtained for 28, 27, and 29 patients, respectively. RESULTS: The treatment groups did not differ significantly in terms of demographics, clinical success rate, microbiological cure rate, or adverse effects. Significantly higher drug compliance was observed in the fosfomycin trometamol group than in the other 2 groups (P<0.05). CONCLUSION: Treatment with a single dose of fosfomycin trometamol was as effective for UTI as the standard course of treatment with amoxicillin clavulanate or cefuroxime axetil. Fosfomycin trometamol may be a preferable treatment for UTI because of its simpler use and better rates of compliance.

RESUMO

INTRODUCTION AND HYPOTHESIS: Abdominal sacrocolpopexy is the gold standard for advanced uterovaginal/cuff prolapse repair; however, early and late bowel complications are of concern. We report our experience with extraperitoneal sacrocolpopexy (ESCP). METHODS: Twenty-three patients who underwent ESCP between 2007 and 2010 were analyzed in this retrospective cohort study. Preoperative assessment included Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact (PFIQ-7) questionnaires, and pelvic examination according to Pelvic Organ Prolapse Quantification (POP-Q) system. Pre-operative findings were compared with postoperative values at the last follow-up using the Wilcoxon sign test. RESULTS: Mean operation time was 86 ± 20 min. Twenty patients were discharged within 24 h. With a mean follow-up of 20 months, objective and subjective cure rates were 91.3% and 86.9%, respectively. No postoperative complications were evident with significant improvement in POP-Q, PFDI-20, and PFIQ-7 scores. CONCLUSIONS: ESCP is a safe and effective sacrocolpopexy procedure that can potentially eliminate the risk of gastrointestinal complications.

RESUMO

Essential oil compositions and antioxidant potentials of fourteen ethanol (75%) root extracts prepared from twelve taxa of the genus Paeonia (Paeoniaceae), including P. arietina Anders., P. daurica Andrews, P. xkayae N. Ozhatay, P. kesrouanensis Thiéb., P. mascula (L.) Miller subsp. arasicola G. Kaynak, ö. Yilmaz & R. Daskin, P. mascula (L.) Miller subsp. bodurii N. Ozhatay, P. cf. mascula L. (Mill.) subsp. mascula (two samples from central and northeastern Anatolia), P. cf. officinalis Retz., P. peregrina Miller (two samples from western and northwestern Anatolia), P. tenuifolia L., P. turcica Davis & Cullen, and P. wittmanniana Hartwiss ex Lindl. were assessed. The chromosome numbers of the root tips of the species were examined using chromosome staining technique with Shiff's reagent under Leitz microscope. The essential oils of the roots of the Paeonia species were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) and the major components were identified as salicylaldehyde (10%-94.4%), cis-myrtanal (5.5%-59.7%), and methyl salicylate (2%-52.2%). Antioxidant potentials were tested against 1,1-diphenyl-2-picrylhydrazyl (DPPH) and nitric oxide (NO) radicals using propyl gallate and rutin as the references. Total phenolic contents of the ethanol extracts were determined using Folin-Ciocalteau's method. The extracts exerted moderate NO scavenger effect and displayed insignificant DPPH radical scavenger activity at 500 microg mL(-1). On the other hand, P. daurica, P. tenuifolia and P. cf. mascula subsp. mascula are diploids with 2n = 10, while other nine taxa are tetraploids with 2n = 20.

RESUMO

OBJECTIVE: To compare the effectiveness of letrozole and clomiphene citrate (CC) in ovulatory patients with borderline male factor infertility, early stage endometriosis, and unexplained infertility. DESIGN: Prospective quasi-randomized trial. SETTING: University infertility clinic. PATIENT(S): Forty-six consecutive patients with ovulatory infertility were recruited. Twenty-five patients (67 cycles) were given CC and 21 patients (52 cycles) were given letrozole. Both drugs were given orally on days 3-7 of menses. INTERVENTION(S): Letrozole, CC, ovulation induction, IUI, timed intercourse. MAIN OUTCOME MEASURE(S): Number of follicles, endometrial thickness, and pregnancy rates. RESULT(S): The median serum E2 concentration on the day of hCG administration in the letrozole and CC groups were 191.5 pmol/L and 476.0 pmol/L, respectively. The median endometrial thickness on the day of hCG were 8 mm in both groups. Ovulation occurred in 81% (42/52) of the letrozole-treated and 85% (57/67) of the CC-treated patients. Pregnancy rate (PR) per cycle was 9% (5/52) in the letrozole group and 12% (8/67) in the CC group. CONCLUSION(S): Letrozole and CC have comparable effectiveness in ovulatory patients with borderline male factor infertility, early stage endometriosis, and unexplained infertility.

RESUMO

OBJECTIVE: To compare the diagnostic accuracy and acceptability of transvaginal sonography (TVS), saline infusion sonography (SIS), and office hysteroscopy (OHS) for detecting intracavitary abnormalities in women with or without abnormal uterine bleeding (AUB). DESIGN: Prospective double-blind study. SETTING: Zekai Tahir Burak Women's Health Education and Research Hospital, Gynecology Clinic (Ankara, Turkey). PATIENT(S): A total of 26 women with AUB and 24 women without AUB were enrolled in this study. INTERVENTION(S): Transvaginal sonography, SIS, and OHS were performed on women scheduled for hysterectomy. MAIN OUTCOME MEASURE(S): Sensitivity, specificity, and positive and negative predictive values of TVS, SIS, and OHS to detect intracavitary abnormalities (with histopathologic findings used as the gold standard), duration of procedure, and pain scores. RESULT(S): The sensitivity and specificity of TVS, SIS, and OHS in detecting intracavitary abnormalities were 56.3% and 72%, 81.3% and 100%, and 87.5% and 100%, respectively. The prevalence of endometrial polyps was not different in women with and without AUB. Saline infusion sonography was less painful than OHS (pain scores of 4.3 and 7.2, respectively). CONCLUSION(S): The diagnostic accuracy of SIS was equal to that of OHS in diagnosing intracavitary abnormalities. Moreover, SIS was less painful than OHS for patients.

RESUMO

BACKGROUND: The purpose of our research was to determine the reliability and accuracy of the Pipelle device in acquiring an adequate and representative endometrial sample and to compare it with D&C histology. MATERIAL/METHODS: A total of 127 women were prospectively included in the study. After Pipelle endometrial sampling, classic dilatation and curettage (D&C) was performed. The histological results of both techniques were compared to assess the accuracy of Pipelle sampling. Prior to endometrial sampling, transvaginal ultrasonography was performed to determine endometrial thickness and pathological lesions, and to exclude other pathologies confined to the pelvis. The outcome measures were specimen adequacy and comparability of histological diagnosis between the Pipelle specimen and the D&C specimen. RESULTS: Although no patient had a failed biopsy procedure, 13 patients had insufficient tissue in the D&C group, and 29 patients in the Pipelle group. In 100 of 127 patients (79%), the Pipelle endometrial histology results were in agreement with the D&C histology results. Pipelle biopsy was unable to diagnose 1 of 5 endometrial hyperplasia cases. CONCLUSIONS: The Pipelle device is a limited endometrial sampling technique for obtaining an adequate and representative endometrial sample. It should be reserved for those patients in whom there is only a minimal risk for endometrial carcinoma, hyperplasia and polyps. Any failure to obtain an endometrial specimen would suggest performing a full endometrial curettage, especially in anamnestically- and sonographically-determined patients at high risk for endometrial cancer.

RESUMO

OBJECTIVE: to determine the enhancement behaviour of the ovaries in women with polycystic ovary syndrome (PCOS) by dynamic contrast-enhanced magnetic resonance (DCE-MR) imaging and to compare these data with those of normal ovulating controls. METHOD: 24 women with PCOS and 12 controls underwent DCE-MR imaging. Dynamic images were acquired before and after injection of a contrast bolus at 30 s and the min of 1, 2, 3, 4 and 5. On postprocessing examination: (i) the ovarian volumes; (ii) the signal intensity value of each ovary per dynamic study; (iii) early-phase enhancement rate; (iv) time to peak enhancement (T(p)); and (v) percentage of washout of 5th min were determined. Data of the ovaries of the women with PCOS and controls were compared with Mann-Whitney U-test. RESULTS: the mean values of T(p) were found to be significantly lower in women with PCOS than in controls (p < 0.05). On the other hand, the mean values of ovarian volume, the early-phase enhancement rate, and percentage of washout of 5th min of ovaries were significantly higher in PCOS patients (p < 0.05). Examination of the mean signal intensity-time curve revealed the ovaries in women with PCOS showed a faster and greater enhancement and wash-out. CONCLUSION: the enhancement behaviour of ovaries of women with PCOS may be significantly different from those of control subjects on DCE-MR imaging examination. In our experience, it is a valuable modality to highlight the vascularization changes in ovarian stroma with PCOS. We believe that improved DCE-MR imaging techniques may also provide us additional parameters in the diagnosis and treatment strategies of PCOS.
