RESUMO
OBJECTIVE: The aim of this retrospective cohort study was to investigate complete blood count parameters in patients with Behçet's disease (BD) who present with oral ulcers and patients with recurrent aphthous stomatitis (RAS) in order to determine whether they could be used as discriminatory biomarkers. PATIENTS AND METHODS: This study was conducted between January 2019 and January 2023. The study population consisted of three groups: patients with BD who had oral ulcer manifestation (n=85, BD-Group), patients with idiopathic RAS (n=186, RAS-Group) and healthy controls (n=90, HC-Group). All data about participants, on their first application, including sociodemographic and clinical data, comorbidity status, laboratory results were collected retrospectively from the hospital computer records and patients' charts. RESULTS: The groups were similar in terms of age (p=0.235) and sex distribution (p=0.450). Mean platelet volume (MPV) and plateletcrit values of the BD-Group were significantly lower, while platelet distribution width (PDW) was significantly higher, compared to the other two groups (p<0.001 for all). Low MPV (<9.15) (56.47% sensitivity and 90.86% specificity), high PDW (≥15.75) (75.00% sensitivity and 94.96% specificity) and low plateletcrit (<0.237) (55.29% sensitivity and 79.46% specificity) could significantly distinguish BD patients with oral ulcer onset from patients with RAS. CONCLUSIONS: PDW, MPV, and plateletcrit may be useful biomarkers in the differential diagnosis of oral ulcers when distinguishing between BD and RAS. However, these results need to be supported by further comprehensive studies.

OBJECTIVE: This study was planned to determine the burnout levels of physicians during the COVID-19 pandemic, and to contribute to taking the necessary measures by determining the associated factors. MATERIALS AND METHODS: This research was designed via Google Online Form as an online survey with questions of Sociodemographic Data Form, Maslach Burnout Inventory and Beck Anxiety Inventory and was conducted with 40 specialist physicians actively working at the Sakarya University Training and Research Hospital. The same questionnaire was re-applied online after two months, and 24 out of 40 physicians were accessed. The SPSS 25 (IBM, Armonk, NY, USA) program was used for the analysis of the data. RESULTS: According to the Maslach Burnout Inventory applied in the pre-test, it was found that the feeling of personal accomplishment was high, emotional burnout was normal, and depersonalization was low. Anxiety and burnout were found to be positively correlated, and there were no statistically significant differences in the average values of the pre-and post-test Maslach Burnout Inventory and Beck Anxiety Inventory scores. CONCLUSIONS: Detecting possible burnout in physicians working in a pandemic, identifying associated factors and taking required measures can be beneficial both for physicians and society from a biopsychosocial perspective.

BACKGROUND: The aim of this study was to evaluate the long-term success rates of pulmonary vein isolation (PVI) using only first-generation cryoballoon (CB-1) and second-generation CB (CB-2) in patients with paroxysmal atrial fibrillation (PAF). PATIENTS AND METHODS: A total of 114 drug-refractory patients with PAF (mean age: 62 ± 10 years; 62.3 % males) were enrolled. All index ablation procedures were performed using a 28-mm CB. All patients were scheduled for outpatient clinic visits, followed by 24-h or 7day Holter electrocardiogram (EGC) evaluation. RESULTS: All PVs in the CB-1 group and 367 of 368 (99.7 %) PVs in the CB-2 group were completely isolated during the index procedure. The most commonly observed complication was phrenic nerve palsy in four (4.3 %) patients with CB-2. The mean follow-up period for CB-1 and CB-2 was 33.4 ± 14.9 and 27.2 ± 10.6 months, respectively. Freedom from AF was 42.9 % for CB-1 and 74.2 % for CB-2 at the end of the follow-up period. The European Heart Rhythm Association score improved in patients without AF recurrence after the procedure (2.8 ± 0.4 vs. 1.2 ± 0.5, p < 0.001), whereas no significant improvement was observed in the symptomatic status of patients with recurrence (2.8 ± 0.4 vs. 2.2 ± 0.9, p = 0.149). CONCLUSION: Second-generation CB provided significantly better clinical outcomes than its predecessor and was associated with low peri- and postprocedural complications.

AIM: To evaluate serum paraoxonase(PON)-1 activity and carotid intima-media thickness (CIMT) in patients with Cytotoxin-associated antigen(CagA)-positive and negative Helicobacter pylori strains. PATIENTS AND METHODS: The study group included a total of 134 individuals, of whom 103 were H. pylori positive, and 31 were H. pylori negative. Five biopsies were collected from each patient for histological examination: two from the antrum, two from the corpus, and one from the incisura angularis. The presence of H. pylori was determined using a modified Gram staining protocol. Peripheral blood was collected from each patient to determine levels of triglyceride, TC, HDL-cholesterol and LDL-cholesterol. IgG antibodies against CagA protein were analyzed by enzyme immunoassays. PON-1 activity was measured by colorimetric method. Carotid intima-media thickness and atherogenic plaques were measured using a grey scale color Doppler ultrasound. Data were analyzed by descriptive and inferential statistics. RESULTS: The right, the left and the mean CIMT were significantly higher in H. pylori (+) group versus H. pylori (-) group (p < 0.001 for all). However, the mean PON-1 concentration was significantly lower in H. pylori (+) group versus H. pylori (-) group (p < 0.001). The right, the left and the mean CIMT of CagA (+) group were significantly higher than that of CagA (-) group and controls, while PON-1 concentrations of CagA (+) group were significantly lower than that of CagA (-) group and controls (for all p = 0.0001). The right, the left and the mean CIMT of CagA (-) group were significantly higher than that of the control group, while the mean PON-1 concentration were significantly lower (for all p = 0.0001). CONCLUSIONS: Decreased PON-1 activity may be an etiopathogenetic factor in increased atherosclerosis in patients with H. pylori infection, especially in those infected with the CagA positive strain.

Mowat-Wilson syndrome is a genetic disease characterized by typical facial features, Hirschsprung disease and multiple congenital abnormalities. MWS is a single gene disorder. One of the most specific clinical signs in MWS is the distinctive face. We report a two-year-old boy with multiple congenital anomalies. He had peripupillary atrophy and gingival hypertrophy different from the literature. The patient was also diagnosed with his clinical findings. These features may be important in Mowat-Wilson syndrome and clinicians should keep these findings in mind.

The aim of the present study was to compare uric acid levels between disease and remisson episodes of bipolar disorder (BD) and healthy individuals and to investigate whether uric acid levels were related with clinical properties and the course. Uric acid levels were compared in 43 BD patients with manic episode, 20 BD patients with depressive episode, 41 BD patients in remission and 43 healthy individuals. Informations regarding disorder was recorded using SKIP-TURK, the severity of episode was measured with Young Mania Rating Scale (YMRS) and Hamilton Depression Rating Scale (HDRS). Uric acid levels were found higher in manic, depressive and euthymic bipolar patients than those in healthy individuals. In cases in remission period, a moderate relation was present between uric acid levels and the age of onset. A moderate relation was found in manic episode between first and second week YMRS scores and uric acid levels, and a strong relation was found in depressive episode between first and second week HDRS scores and uric acid levels. While decrease in uric acid levels in manic episode was found to be associated with the decrease in YMRS scores, no such relation was shown in depressive episode. Our findings stress the impairment in purinergic functions in all episodes of BD. This impairment seems to be associated with clinical properties of BD.

BACKGROUND: Bone marrow-derived circulating progenitor cells (BM-CPCs) in patients with coronary heart disease are impaired with respect to number and functional activity. However, the relation between the functional activity of BM-CPCs and the number of diseased coronary arteries is yet not known. We analyzed the influence of the number of diseased coronary arteries on the functional activity of BM-CPCs in peripheral blood (PB) in patients with ischemic heart disease (IHD). METHODS: The functional activity of BM-CPCs was measured by migration assay and colony forming unit in 120 patients with coronary 1 vessel (IHD1, n = 40), coronary 2 vessel (IHD2, n = 40), coronary 3 vessel disease (IHD3, n = 40) and in a control group of healthy subjects (n = 40). There was no significant difference of the total number of cardiovascular risk factors between IHD groups, beside diabetes mellitus (DM), which was significantly higher in IHD3 group compared to IHD2 and IHD1. RESULTS: The colony-forming capacity (CFU-E: p < 0.001, CFU-GM: p < 0.001) and migratory response to stromal cell-derived factor 1 (SDF-1: p < 0.001) as well as vascular endothelial growth factor (VEGF: p < 0001) of BM-CPCs were reduced in the group of patients with IHD compared to control group. The functional activity of BM-CPCs was significantly impaired in patients with IHD3 as compared to IHD1 (VEGF: p < 0.01, SDF-1: p < 0.001; CFU-E: p < 0.001, CFU-GM: p < 0.001) and to IHD2 (VEGF: p = 0.003, SDF-1: p = 0.003; CFU-E: p = 0.001, CFU-GM: p = 0.001). No significant differences were observed in functional activity of BM-CPCs between patients with IHD2 and IHD1 (VEGF: p = 0.8, SDF-1: p = 0.9; CFU-E: p = 0.1, CFU-GM: p = 0.1). Interestingly, the levels of haemoglobin AIc (HbAIc) correlated inversely with the functional activity of BM-CPCs (VEGF: p < 0.001, r = -0.8 SDF-1: p < 0.001, r = -0.8; CFU-E: p = 0.001, r = -0.7, CFU-GM: p = 0.001, r = -0.6) in IHD patients with DM. CONCLUSIONS: The functional activity of BM-CPCs in PB is impaired in patients with IHD. This impairment increases with the number of diseased coronary arteries. Moreover, the regenerative capacity of BM-CPCs in ischemic tissue further declines in IHD patients with DM. Furthermore, monitoring the level of BM-CPCs in PB may provide new insights in patients with IHD.

BACKGROUND: Autologous bone marrow cell transplantation (BMCs-Tx) is a promising novel option for treatment of cardiovascular disease. In this study we analyzed whether intracoronary autologous freshly isolated BMCs-Tx have beneficial effects on cardiac function in patients with ischemic heart disease (IHD). RESULTS: In this prospective nonrandomized study we treated 12 patients with IHD by freshly isolated BMCs-Tx by use of point of care system and compared them with a representative 12 control group without cell therapy. Global ejection fraction (EF) and infarct size area were determined by left ventriculography.Intracoronary transplantation of autologous freshly isolated BMCs led to a significant reduction of infarct size (p < 0.001) and an increase of global EF (p = 0.003) as well as infarct wall movement velocity (p < 0.001) after 6 months follow-up compared to control group. In control group there were no significant differences of global EF, infarct size and infarct wall movement velocity between baseline and 6 months after coronary angiography. Furthermore, we found significant decrease in New York Heart Association (NYHA) as well as significant decrease of B-type natriuretic peptide (BNP) level 6 months after intracoronary cell therapy (p < 0.001), whereas there were no significant differences in control group 6 months after coronary angiography. CONCLUSIONS: These results demonstrate that intracoronary transplantation of autologous freshly isolated BMCs by use of point of care system is safe and may lead to improvement of cardiac function in patients with IHD.

Autologous bone marrow cell transplantation (BMCs-Tx) is a promising novel option for treatment of cardiovascular disease. We analysed in a randomized controlled study the influence of the intracoronary autologous freshly isolated BMCs-Tx on the mobilization of bone marrow-derived circulating progenitor cells (BM-CPCs) in patients with acute myocardial infarction (AMI). Sixty-two patients with AMI were randomized to either freshly isolated BMCs-Tx or to a control group without cell therapy. Peripheral blood (PB) concentrations of CD34/45(+) - and CD133/45(+)-circulating progenitor cells were measured by flow cytometry in 42 AMI patients with cell therapy as well as in 20 AMI patients without cell therapy as a control group on days 1, 3, 5, 7, 8 and 3, 6 as well as 12 months after AMI. Global ejection fraction (EF) and the size of infarct area were determined by left ventriculography. We observed in patients with freshly isolated BMCs-Tx at 3 and 12 months follow up a significant reduction of infarct size and increase of global EF as well as infarct wall movement velocity. The mobilization of CD34/45(+) and CD133/45(+) BM-CPCs significantly increased with a peak on day 7 as compared to baseline after AMI in both groups (CD34/45(+): P < 0.001, CD133/45(+): P < 0.001). Moreover, this significant mobilization of BM-CPCs existed 3, 6 and 12 months after cell therapy compared to day 1 after AMI. In control group, there were no significant differences of CD34/45(+) and CD133/45(+) BM-CPCs mobilization between day 1 and 3, 6 and 12 months after AMI. Intracoronary transplantation of autologous freshly isolated BMCs by use of point of care system in patients with AMI may enhance and prolong the mobilization of CD34/45(+) and CD133/45(+) BM-CPCs in PB and this might increase the regenerative potency after AMI.

BACKGROUND: Bone marrow-derived circulating progenitor cells (BM-CPCs) in patients with coronary heart disease are impaired with respect to number and mobilization. However, it is unknown whether the mobilization of BM-CPCs depends on the number of diseased coronary arteries. Therefore, in our study, we analysed the correlation between the diseased coronary arteries and the frequency of CD34/45+ BM-CPCs in peripheral blood (PB) in patients with ischemic heart disease (IHD). METHODS: The frequency of CD34/45+ BM-CPCs was measured by flow cytometry in 120 patients with coronary 1 vessel (IHD1, n = 40), coronary 2 vessel (IHD2, n = 40), coronary 3 vessel disease (IHD3, n = 40) and in a control group of healthy subjects (n = 40). There was no significant difference of the total number of cardiovascular risk factors between IHD groups, beside diabetes mellitus (DM), which was significantly higher in IHD3 group compared to IHD2 and IHD1 groups. RESULTS: The frequency of CD34/45+ BM-CPCs was significantly reduced in patients with IHD compared to the control group (CD34/45+; p < 0.001). The frequency of BM-CPCs was impaired in patients with IHD3 compared to IHD1 (CD34/45+; p < 0.001) and to IHD2 (CD34/45+; p = 0.001). But there was no significant difference in frequency of BM-CPCs between the patients with IHD2 and IHD1 (CD34/45+; p = 0.28). In a subgroup we observed a significant negative correlation between levels of hemoglobin AIc (HbAIc) and the frequency of BM-CPCs (CD34/45+; p < 0.001, r = -0.8). CONCLUSIONS: The frequency of CD34/45+ BM-CPCs in PB is impaired in patients with IHD. This impairment may augment with an increased number of diseased coronary arteries. Moreover, the frequency of CD34/45+ BM-CPCs in ischemic tissue is further impaired by diabetes in patients with IHD.

BACKGROUND: The influence of the number of diseased coronary arteries on the mobilization of CD133/45(+) bone marrow-derived circulating progenitor cells (BM-CPCs) in peripheral blood (PB) in patients with ischemic heart disease (IHD) was analyzed. METHODS AND RESULTS: Mobilization of CD133/45(+) BM-CPCs by flow cytometry was measured in 120 patients with coronary 1 vessel (IHD1, n=40), coronary 2 vessel (IHD2, n=40), and coronary 3 vessel disease (IHD3, n=40), and in a control group (n=40). The mobilization of CD133/45(+) BM-CPCs was significantly reduced in patients with IHD compared to the control group (P<0.001). The mobilization of CD133/45(+) BM-CPCs was impaired in patients with IHD3 compared to IHD1 (P<0.001) and to IHD2 (P<0.001). But there was no significant difference in mobilization of CD133/45(+) BM-CPCs between the patients with IHD2 and IHD1 (P=0.35). Moreover, we found significantly reduced CD133/45(+) cell mobilization in patients with a high SYNTAX-Score (SS) compared to a low SS (P<0.001) and an intermediate SS (P<0.001). In subgroup analyzes, we observed a significantly negative correlation between levels of hemoglobin A(1c) and the mobilization of CD133/45(+) BM-CPCs (P=0.001, r=-0.6). CONCLUSIONS: The mobilization of CD133/45(+) BM-CPCs in PB is impaired in patients with IHD. This impairment might augment with increased number of diseased coronary arteries. Moreover, mobilization of CD133/45(+) BM-CPCs in ischemic tissue is further impaired by diabetes in patients with IHD.

OBJECTIVES: There is growing evidence that intracoronary autologous bone marrow cells transplantation (BMCs-Tx) in patients with chronic myocardial infarction beneficially affects postinfarction remodelling. In this randomized controlled study we analyzed the influence of intracoronary autologous freshly isolated bone marrow cells transplantation by use of point of care system on cardiac function and on the functional activity of bone marrow derived circulating progenitor cells (BM-CPCs) in patients with ischemic heart disease (IHD). METHODS: 56 patients with IHD were randomized to either received freshly isolated BMC-Tx or a control group that did not receive cell therapy. The functional activity of BM-CPCs in peripheral blood (PB) was measured by migration assay and colony forming unit assay pre- and 3, 6 as well as 12 months after procedure. Global ejection fraction (EF) and infarct size area were determined by left ventriculography. RESULTS: Intracoronary transplantation of autologous freshly isolated BMCs led to a significant reduction of infarct size and an increase of global EF as well as infarct wall movement velocity after 3 and 12 months follow-up compared to control group. The colony-forming capacity of BM-CPCs significantly increased 3, 6 and 12 months after cell therapy compared to pre BMCs-Tx and control group (CFU-E: p < 0.001, CFU-GM: p < 0.001). Likewise, we found significant increase of migratory response to stromal cell-derived factor 1 (SDF-1) and vascular endothelial growth factor (VEGF) after cell therapy compared to pre BMCs-Tx (SDF-1: p < 0.001, VEGF: p < 0.001) and to control (SDF-1: p < 0.001, VEGF: p < 0.001). There was no significant difference of migratory- and colony forming capacity between pre- and 3, 6, 12 months after coronary angiography in control group without cell therapy. CONCLUSIONS: Intracoronary transplantation of autologous freshly isolated BMCs by use of point of care system may lead to improvement of BM-CPCs functional activity in peripheral blood, which might increase the regenerative potency in patients with IHD.

The aim of this study was to assess the preference of pregnant women for mode of delivery in an uncomplicated pregnancy and reasons of their choice, also to determine if maternal characteristics were predictors of maternal preference. Pregnant women applying to the antenatal clinic for a routine control visit were recruited. After verbal consents, a questionnaire was administered to 1,588 pregnant women. Of the women questioned, 84.1% opted for vaginal delivery whereas only 15.9% opted for an elective caesarean delivery. The main reasons for vaginal delivery preference were; earlier healing and earlier hospital discharge, being a more physiological way of delivery and previous vaginal delivery history. The most common reasons for choosing caesarean delivery were; fear of vaginal delivery, tubal ligation demand and to avoid labour pain. Educational status, occupation and gestational age were not found to be influencing factors but age, parity and monthly income were found to be influencing factors for maternal preference.

OBJECTIVE: To determine the efficacy of intravenous (i.v.) paracetamol for decreasing pain associated with fractional curettage. MATERIALS AND METHODS: This double-blind, randomised, placebo-controlled trial included 70 women who underwent fractional curettage. Patients were randomly assigned to receive i.v. infusion of either 1000 mg paracetamol (n = 36) or 0.9% normal saline as placebo (n = 34) prior to the procedure. The main outcome measure was the intensity of pain assessed by a 10-cm visual analogue scale. Pain scoring was performed at t(1) = prior to the procedure, t(2) = during the procedure and t(3) = 30 min after the procedure. Statistical analysis was performed using the Student's t-test, chi-squared and Pearson's correlation analysis. RESULTS: The pain scores at t(2) and t(3) were significantly higher than the score at t(1) in both groups. There was no statistically significant difference between the pain scores at t(1), t(2) and t(3) among the two groups. Menopausal status had no effect on the pain scores and on the treatment outcome. The pain scores prior to the procedure were significantly higher in women with a history of endometrial curettage when compared with women who have no history. CONCLUSIONS: Fractional curettage is associated with mild pain. We were unable to detect a significant difference in pain scores in patients undergoing fractional curettage when comparing the use of i.v. paracetamol with placebo. History of prior endometrial curettage seems to be a predictor of the basal pain scores at admission although it does not affect the pain intensity related to the procedure.

BACKGROUND AND OBJECTIVE: The anaesthetic method for intracranial neurosurgery must provide haemodynamic stability on emergence and allow early evaluation of the neurological status. In this study, we examined the effects of the alpha-2 agonist dexmedetomidine given at the end of the procedure to prevent hyperdynamic responses during extubation and to allow a comfortable and high-quality recovery. METHODS: Forty ASA I-III patients, aged between 18 and 75 yr, having elective intracranial surgery, were divided into two random groups. Standard procedures and drugs were used for monitoring, induction and maintenance. Isoflurane was reduced by 50% 5 min before the end of the surgery, and in Group I dexmedetomidine 0.5 microg kg(-1) and in Group II 20 mL of 0.9% NaCl were administrated intravenously over 60 s. Systolic, diastolic and mean arterial pressures, and heart rate were recorded before intravenous administration and also at 1, 3 and 5 min after administration, 1 min before extubation, during extubation, 1, 3, 5, 10, 15, 20 and 30 min after extubation. Duration of extubation and recovery were noted, and the quality of extubation was evaluated on a 5-point scale. RESULTS: Mean arterial pressure and heart rate were significantly higher in Group II than in Group I (P < 0.01). There were no statistically significant differences between groups regarding the duration of extubation and recovery (P > 0.05). Extubation quality score of all the patients were 1 in Group I and in Group II, the quality scores were 1 for 35%, 2 for 45% and 3 for 20% of the patients (P < 0.001). None of the patients in Group I and Group II showed respiratory depression, nausea or vomiting. CONCLUSION: Without interfering in recovery time, dexmedetomidine 0.5 microg kg(-1) administered 5 min before the end of surgery stabilizes haemodynamics, allows easy extubation, provides a more comfortable recovery and early neurological examination following intracranial operations.

In many cases marine organisms and especially their diverse developmental stages are difficult to identify by morphological characters. DNA-based identification methods offer an analytically powerful addition or even an alternative. In this study, a DNA microarray has been developed to be able to investigate its potential as a tool for the identification of fish species from European seas based on mitochondrial 16S rDNA sequences. Eleven commercially important fish species were selected for a first prototype. Oligonucleotide probes were designed based on the 16S rDNA sequences obtained from 230 individuals of 27 fish species. In addition, more than 1200 sequences of 380 species served as sequence background against which the specificity of the probes was tested in silico. Single target hybridisations with Cy5-labelled, PCR-amplified 16S rDNA fragments from each of the 11 species on microarrays containing the complete set of probes confirmed their suitability. True-positive, fluorescence signals obtained were at least one order of magnitude stronger than false-positive cross-hybridisations. Single nontarget hybridisations resulted in cross-hybridisation signals at approximately 27% of the cases tested, but all of them were at least one order of magnitude lower than true-positive signals. This study demonstrates that the 16S rDNA gene is suitable for designing oligonucleotide probes, which can be used to differentiate 11 fish species. These data are a solid basis for the second step to create a "Fish Chip" for approximately 50 fish species relevant in marine environmental and fisheries research, as well as control of fisheries products.

We report a case of cervical ectopic pregnancy successfully treated with systemic methotrexate. Conservative management with single-dose methotrexate was undertaken, but owing to the failure of human chorionic gonadotropin (hCG) levels to fall by 15% by day 7 and the persistence of fetal cardiac activity, two further doses of methotrexate were required. The patient's hCG levels were monitored, and repeat transvaginal ultrasonography was performed until complete resolution of the pregnancy by spontaneous miscarriage. We describe the ultrasonographic findings, which showed that the sac size increased despite treatment.

Local and systemic release of transforming growth factor beta 1 (TGF-beta1) is known to increase during the process of fracture healing and this cytokine stimulates bone healing. The majority of the non steroidal anti inflammatory drugs (NSAIDs) inhibit fracture healing. Granulocyte colony stimulating factor (G-CSF) is a hematopoietic growth factor that stimulates bone marrow. In this study, the effects of the NSAID naproxen sodium, G-CSF, and both of them in combination on the TGF-beta1 serum level in rats with tibia fractures were measured and fracture healing was evaluated by histopathologic and radiologic examination. The TGF-beta1 serum levels obtained on day one (24 h after fracture but before administration of naproxen or G-CSF) were found to be similar in all of the five groups (p > 0.05). At the end of the first week, TGF-beta1 levels were significantly lower in naproxen-treated rats than those of the other groups excluding control (p = 0.002). Similar changes in TGF-beta1 levels were found at the end of the second and fourth weeks. TGF-beta1 levels were significantly higher in G-CSF-treated rats at the end of the first, second and fourth weeks (p < 0.05). Fracture healing scores measured with histopathological and radiological methods were higher in G-CSF-treated rats than in naproxen-treated ones. When both naproxen and G-CSF were given, the scores resumed to normal. The results point to the negative effect of naproxen sodium on fracture healing is due to its decreasing effect on the level of TGF-beta1, which may be a new possible mechanism. Moreover, this negative effect can be inhibited by the use of G-CSF.

The objective of the present study was to quantify the magnitude of the association between the change in triglycerides and high-density lipoprotein (HDL) cholesterol levels with the use of tibolone and transdermal estrogen in postmenopausal women with hypertriglyceridemia and normotriglyceridemia. This prospective randomized study enrolled 140 postmenopausal women who had all been hysterectomized for almost a year or more. All subjects completed the 3-month follow-up. The 140 patients were divided into two groups: 70 were given transdermal 17beta-estradiol 0.05 mg/day, and 70 were given tibolone 2.5 mg/day. We compared the effects of tibolone and transdermal 17beta-estradiol on lipids and dimacteric symptoms of the patients. To evaluate the effects of tibolone and transdermal estrogens on triglycerides and HDL cholesterol in postmenopausal women with normotriglyceridemia and hypertriglyceridemia, the women were assigned to five groups according to triglyceride levels (0-100, 101-200, 201-300, 301-400 and > or = 401 mg/dl). We compared changes in the triglyceride and HDL cholesterol levels of each group after treatment. All 140 postmenopausal women completed the trial. No significant differences were found in baseline characteristics of the patients. The tibolone group showed a 22.6% decrease whereas the transdermal estrogen group had a 10.9% decrease in the mean triglyceride levels after 3 months of treatment. The mean decrease of triglyceride level with transdermal estradiol was approximately 11% in normotriglyceridemic and hypertriglyceridemic postmenopausal women. The mean decrease of triglyceride level was 17% in the normotriglyceridemic group and 22-30% in the hypertriglyceridemic groups with tibolone. While the mean HDL cholesterol level increased in the transdermal estrogen group (3.6%), it decreased in the tibolone group (9.3%). We found that tibolone decreased triglyceride levels much more than did transdermal estradiol. However, HDL cholesterol was decreased by tibolone and increased by transdermal estradiol. Tibolone had a more marked decreasing effect in postmenopausal women who had higher initial triglyceride levels. It is suggested that the beneficial effect of tibolone on the cardiovascular system might be greater in women with a high level of triglycerides.

OBJECTIVE: The purpose of this study was to determine the reliability of the vaginal washing-fluid prolactin assay for the diagnosis of premature rupture of membranes (PROM) and to determine a diagnostic cut-off value. STUDY DESIGN: Seventy pregnant women between 11 and 40 weeks of gestation who were admitted with vaginal fluid leakage were included in the study group, and were then further subdivided into two subgroups according to amniotic fluid pooling and nitrazine paper test results. Group 1 was the 'confirmed PROM group', positive for both pooling and nitrazine (38 patients). Group 2 was the 'suspected but unconfirmed PROM group' which had possible pooling and/or nitrazine (32 patients). Seventy pregnant women between 11 and 40 weeks of gestation without any complaint and complication were included in the control group (group 3). All patients underwent vaginal washing-fluid sampling and prolactin level determination. For the statistical analysis one-way analysis of variance, Tukey multiple comparison test, chi2 test and receiver operating characteristic (ROC) curve analysis were used. RESULTS: Geometric mean values of vaginal washing-fluid prolactin levels were 616.59 microIU/ml for group 1, 23.98 microIU/ml for group 2 and 10 microIU/ml for group 3 (p < 0.0001). The optimal diagnostic cut-off value was found to be 30 microIU/ml with 95% sensitivity, 78% specificity, 84% positive predictive value, 93% negative predictive value, 87% accuracy and 11.30 relative risk. CONCLUSIONS: We recommend vaginal washing-fluid prolactin level determination as an alternative diagnostic method for PROM.
