Publication trends in micro-CT endodontic research: a bibliometric analysis over a 25-year period.

AIM: To conduct a bibliographic analysis of the research studies published in Endodontics using micro-computed tomography (micro-CT) as an analytical tool over a 25-year period. METHODOLOGY: The Web of Science electronic database was accessed, and an advanced search using strict criteria was undertaken from January 1995 to June 2020 for studies in the field of Endodontics that used micro-CT as an analytical tool. A further search was conducted between January and August of 2020 for a combination of specific terms and descriptors. For each selected article, the following parameters were recorded: field of the study, analysed specimen, publication title and year, authorship, journal of publication, institution and country of origin, collaborating institutions and countries, and number of citations. The acquired data were analysed using descriptive statistics and graphical mappings. RESULTS: The screening process identified 877 relevant articles that were classified into 30 thematic categories. The main fields of research were root canal preparation (23.8%), root canal anatomy (17.4%), canal filling (9.2%) and root canal retreatment (7.0%). The most productive half-decade comprised the period of 2015-2019 (n = 513; 58.5%), with the highest number of articles published in 2019 (n = 146; 16.6%). The authors who lead the list as first authors were G De-Deus, A Keles, F Paqué, MA Versiani and Y Gu, respectively, whilst Versiani was the most productive (n = 51). The leading countries regarding the number of studies were Brazil, China and Turkey with 236, 130 and 65 publications, respectively. The University of São Paulo (n = 90; 10.3%) followed by Wuhan University (n = 37; 4.2%) and the University of Zurich (n = 18; 2.1%) were the prominent contributors by producing the largest number of articles, whilst the University of Zurich was the most-cited institution. The selected studies were published in 140 scientific journals, but the Journal of Endodontics and International Endodontic Journal accounted for almost 50% of the publications. CONCLUSION: This bibliometric analysis portrayed an original and comprehensive view on the progress and trends of the use of micro-CT technology in endodontic research, and enabled a deep understanding of the development process in this field over the last 25 years.

Predictive value of procalcitonin and IL-6 versus cervical length for the admission-to-delivery interval in preterm labour.

OBJECTIVE: The authors aimed to determine whether concentrations of IL-6 and procalcitonin in maternal circulation can be used and compared with cervical length to predict the admission-to-delivery interval in preterm labour. MATERIALS AND METHODS: Forty patients complicated with preterm labour between 24-34 weeks of gestation and having preterm birth were included in the study group. Fortyfour healthy pregnant women at similar gestational ages and having term labour ('> 37 weeks) were included in control group. Maternal concentrations of IL-6 was measured by an enzyme-linked immunosorbent assay (ELISA) and procalcitonin was measured by immunoturbidimetry with using human procalcitonin reagent kit. Transvaginal ultrasound to assess cervical length was perforned. RESULTS: Receiver operator characteristic (ROC) analysis results of IL-6 and procalcitonin for prediction of preterm delivery (PTD)< 48 hours, < seven days, <32 weeks, < 34 weeks, and < 37 weeks were not statistically significant (p > 0.05). ). It was shown through ROC analysis, that only cervical length had area under curve (AUC) 0.692 (0.511-0.873,p = 0.044) at cut off value ≤ 3.64 cm, AUC 0.758 (0.574-0.943, p = 0.015) at cut off value ≤ 3.50 cm, AUC 0.716 (0.553-0.879,p = 0.032) at cut off value < 3.80 cm, in predicting PTD within seven days, <32 weeks and < 37 week, respectively. CONCLUSION: This study suggests that in preterm labour, although IL-6 and procalcitonin have unsatisfactory predictive value for the admission-to-delivery interval, cervical length has better predictive values for the admission-to-delivery interval.

Knowledge and attitude changes of pregnant women regarding prenatal screening and diagnostic tests after counselling.

OBJECTIVES: This study aimed to reveal the knowledge level of pregnant women about prenatal diagnostic tests, Down syndrome (DS) and amniocentesis, their attitudes toward uptaking these tests, undergoing amniocentesis, and the termination of pregnancy. It also aimed to evaluate the effects of providing information, as well as a written information brochure about all the issues concerning women's knowledge and attitudes. MATERIALS AND METHODS: The gynecologists provided verbal and written information on prenatal screening tests (PSTs) and invasive prenatal diagnostic tests. Data were collected using an anonymous questionnaire, which was designed by the researchers on the basis of the literature. RESULTS: Knowledge of both DS and amniocentesis was found to be significantly higher after the education (p = 0.000 and p = 0.000, respectively). Attitudes toward amniocentesis changed significantly after the education. CONCLUSIONS: This study has shown that women had an inadequate knowledge about PSTs, DS, and amniocentesis. It has also revealed that education provided by gynecologists along with a written brochure of information tended to increase women's knowledge about PSTs.

The synergistic effect of ω3 and Vit D3 on glycemia and TNF-α in islet transplantation.

The current treatment of type 1 diabetes consists of insulin administration. Transplantation of islets of Langerhans is considered very favorable because the full effect of insulin treatment cannot be obtained in severe cases. Although agents such as omega-3 (ω3) and vitamin D3 (Vit D3) are known to contribute to the success of islet allo-transplantation (ITX), in this study we aimed to experimentally determine their effects on glycemia and TNF-α production. Wistar albino rats, which were used as recipients, were given ω3, Vit D3, and islets by gavage, and intraperitoneal- and intraportal injections, respectively. Daclizumab (DAC) was used for immunosuppression. Glycemia levels decreased in rats treated with ω3 and vit D3. TNF-α increased in all groups due to application of STZ. After ITX (day +1), the weakest increase was observed in the ω3 + Vit D3 group. In the ITX+DAC group, compared with that of ITX only, DAC was shown to decrease levels of TNF- α following ITX, only in control group, however, similar levels of TNF-α were observed in other groups. The values in the treated groups were already lower than those of the controls in the ITX group and also remained almost equal in the ITX+DAC group. We suggest that the use of ω3 and Vit D3 together will improve the pro-inflammatory aspect encountered during and after ITXs, and contribute to the reduction of the dose of immunosuppressants in these procedures.

Impacts of maternal anxiety on non-stress test parameters.

OBJECTIVE: To determine the association between antenatal maternal anxiety with non-stress test (NST) parameters, which is an indi- cator test of fetal well-being in the third trimester. MATERIALS AND METHODS: Between January and December of 2013, 212 pregnant women, with 36-41 weeks of gestation were assessed with measures of distress and anxiety with Beck Anxiety Inventory (BAI) and with NST. The new National Institute Child Health and Human Development (NICHD) 2008 guideline criteria were used for interpretation of NST. Anxiety scores were grouped as minimal, mild, moderate, and severe. The impact of anxiety on NST parameters were investigated. RESULT: Anxiety scores were inversely correlated with fetal heart rate (FHR) accelerations (r = -0.631, and r = -0.855), number of fetal movements (r = -0.633, r = -0.860), FHR variability scores (r = -0.650, r = -0.877). and NST scores (r = -0.505, r = 0.729), (for all p < 0.001). NST scores were lower in severe anxiety group than the others. CONCLUSION: The study showed that severe form of anxiety significantly affects NST parameters in near-term pregnancies.

Comparison of diagnostic methods for evaluation of postmenopausal bleeding.

OBJECTIVE: To determine and compare diagnostic accuracy parameters of saline infusion sonohysterography (SIS), transvaginal ultrasonography (TVUSG), and hysteroscopy (H/S) based on histopathologic results which are accepted to be the gold standard in patients with postmenopausal bleeding (PMB). MATERIALS AND METHODS: Forty-seven patients who applied to Gynecology clinic of Adnan Menderes University, School of Medicine with PMB complaint aged between 43-76 years were included to the study. Fractioned curettage (F/C) and H/S guided biopsy were used for endometrial sampling. Diagnostic accuracy parameters (sensitivity, specificity, and positive and negative predictive values) of different methods; TVUSG, SIS, and H/S based on histopathologic findings were investigated. RESULTS: Specificity and sensitivity values calculated based on histopathologic results for all endometrial cavity lesions were found, respectively: 44.4% and 25% for TVUSG, 88.8% and 60.7% for SIS, and 100% and 77.7% for HIS. CONCLUSION: SIS is superior to TVUSG and as effective as H/S for assessment of endometrial cavity lesions in patients with PMB.

Posterior reversible encephalopathy syndrome in obstetric patients. Report of three cases with literature review.

Posterior reversible encephalopathy syndrome (PRES) is a serious clinico-neuroradiological maternal complication in pregnancy. Although it has various etiologies such as hypertensive encephalopathy, renal failure, autoimmune disorders, sepsis, multiple organ failure, and treatment with immunosuppressant or cytotoxic agents, pregnancy and postpartum complicated by hypertensive disorders more frequently lead to this condition. PRES is clinically characterized by headache, confusion, seizures, vomiting, and visual disturbances with radiographic vasogenic edema especially affecting symmetrical parietal and occipital lobes. The underlying pathophysiology is still a matter of debate. Prompt recognition and early intervention greatly improve the prognosis, so that obstetricians should be well aware of this rare entity. Timely imaging is of crucial importance especially in patients with an uncertain diagnosis for determining the appropriate treatment and preventing the possible development of neurologic deficits. In the present report, three cases of PRES are presented with clinical and radiological findings in pregnancies complicated by severe pre-eclampsia and eclampsia. The latest literature in the field is also carefully reviewed.

Is near-infrared spectroscopy a promising predictor for early intracranial hemorrhage diagnosis in the Emergency Department?

Intracranial hemorrhage (ICH) is a serious medical condition that can lead to significant morbidity and mortality if not diagnosed and treated promptly. Early detection and treatment are essential for improving the outcome in patients with ICH. Near-infrared spectroscopy (NIRS) is a non-invasive imaging technique that has been used to detect changes in brain tissue oxygenation and blood flow in various conditions. The aim of this study was to investigate the predictive potential of NIRS for early diagnosis of ICH in patients presenting to the Emergency Department (ED) triage with headache. A total of 378 patients were included in the study. According to the final diagnosis of the patients, 4 groups were formed: migraine, tension-cluster headache, intracranial hemorrhage and intracranial mass, and control group. Cerebral NIRS values "rSO2" were measured at the first professional medical contact with the patient. The right and left rSO2 (RrSO2, LrSO2) were significantly lower and the rSO2 difference was significantly higher in the intracranial hemorrhage group compared to all other patient groups (P<0.001). The cut-off values determined in the receiver operating characteristics (ROC) analysis were RrSO2 ≤67, LrSO2 ≤67, and ΔrSO2 ≥9. This study found that a difference of more than 9 in cerebral right-left NIRS values can be a non-invasive, easy-to-administer, rapid, and reliable diagnostic test for early detection of intracranial bleeding. NIRS holds promise as an objective method in ED triage for patients with intracranial hemorrhage. However, further research is needed to fully understand the potential benefits and limitations of this method.

Evaluations of the radial peripapillary, macular and choriocapillaris microvasculature using optical coherence tomography angiography in patients with systemic sclerosis.

PURPOSE: To analyze the macular microvascular (MMV) architecture, radial peripapillary capillary (RPC) network and choriocapillaris using optical coherence tomography angiography (OCT-A) in patients with systemic sclerosis (SSc) without systemic comorbidities. METHODS: The vessel densities (VDs) of the MMV, foveal avascular zone (FAZ) parameters, choriocapillaris flow areas (CCFAs), RPC VDs, and optic nerve head (ONH) parameters were measured by OCT-A. Retinal thickness and subfoveal choroidal thickness (SFCT) were measured by spectral-domain optical coherence tomography (SD-OCT). The SD-OCT and OCT-A measurements of 53 eyes of 30 SSc patients were compared with 61 eyes of 33 healthy controls. RESULTS: In the MMV analysis, a decrease in the VDs of the superficial capillary plexus and an increase in the FAZ area, FAZ perimeter and non-flow area were detected in the SSc group compared to the controls (P=0.007, P=0.001, P=0.029, P=0.018, and P=0.039, respectively). While there was a decrease in SFCT, no change was found in CCFA (P=0.001 and P=0.902, respectively). The RPC analysis revealed a decrease in the VDs of all vessels for the entire area and the intradisc area, as well as the VDs of the small vessels for the intradisc area (P=0.021, P=0.001, and P=0.003, respectively). In the ONH analysis, there was an increase in the C/D area ratios and cup volumes, and a decrease in the rim areas and nasal quadrant retinal nerve fiber layer thickness (P=0.004, P=0.004, P=0.013, and P=0.032, respectively). CONCLUSION: Decreases in RPC and MMV VDs and changes in ONH parameters were found in OCT-A measurements in patients with SSc.

Is the dopamine D3 receptor mRNA on blood lymphocytes help to for identification and subtyping of schizophrenia?

Schizophrenia is one of the neuropathological disorders, which are associated with dopamine and its receptors. In recent years, it has been shown that mRNA of D3, D4 and D5 dopamine receptor (DRD3, DRD4, DRD5) subtypes is expressed in human peripheral blood lymphocytes (PBL). A total 55 schizophrenic patients and 51 healthy subjects were included in the study to investigate the levels of DRD3 mRNA in PBL of schizophrenic patients and whether DRD3 mRNA level in PBL can serve as peripheral marker for schizophrenia. RNA was isolated from lymphocytes of both groups and reverse transcriptase polymerase chain reaction (RT-PCR) was performed for DRD3 mRNA. We found a significant difference in PBL DRD3 mRNA levels among schizophrenia subtypes (P=0.030) while no difference was detected between control subjects and schizophrenics. We concluded that the levels of DRD3 mRNA can help understanding and severity of clinical manifestations in schizophrenia.

Peripheral primitive neuroectodermal tumor (PNET) of the vulva: a case report.

INTRODUCTION: Ewing's sarcoma/peripheral primitive neuroectodermal tumor (ES-PNET) is a high-grade malignant neoplasm that often develops in the skeletal system. Primary extraskeletal ES-PNET is an uncommon condition that rarely affects the female genital tract. Tumors in the ovary, cervix, and uterine corpus and vulva are occasionally reported. Reports on the Ewing family of tumors involving the vulva are extremely rare in the relevant literature. Only a few cases of vulvar ES-PNET have so far been reported. CASE PRESENTATION: A 14-year-old adolescent girl presented to the clinic with a 4-month history of a left vulvar mass. The mass was excised under general anesthesia, and re-resection was performed three weeks later to obtain negative microscopic margins. The patient received chemotherapy and radiotherapy; however, she died of pulmonary metastasis within nine months of the initial surgery. CONCLUSION: In summary, we describe a rare case of vulvar ES-PNET with distinct rosette-like structures in a 14-year-old adolescent girl with a very poor prognosis.

Papillary serous adenocarcinoma of the uterine cervix: a case report.

Papillary serous adenocarcinoma of the endocervix (PSAE) is a rarely encountered neoplasm. The literature includes only a limited number of well documented case studies. The present study reports a case of papillary serous adenocarcinoma originating from the endocervix.

Rectal cancer in pregnancy: a case report.

Rectal cancer in pregnancy is a rare but a life-threatening disease. This paper presents a case of rectal cancer in pregnancy, discussed in light of the literature.

Labial fusion first diagnosed during pregnancy with voiding difficulty and its management: a case report.

INTRODUCTION: Labial fusion is described as partial or complete adherence of the labia minora. Adhesions of the labia are extremely rare in the reproductive population with only a few cases described in the literature and none reported with pregnancy. CASE PRESENTATION: A 24-year-old woman who had extensively fused labia with a pinhole opening at the upper midline with menstrual delay was diagnosed at six weeks of pregnancy. The case and its management are presented. CONCLUSION: The condition was treated surgically with complete resolution of the urinary symptoms.

Lost intrauterine contraceptive device inserted 42 years before: a case report.

OBJECTIVE: The management of a lost abdominal intrauterine contraceptive device (IUD) is discussed together with a review of the relevant literature. THE CASE: The IUD is one of the most commonly used, effective, cheap and safe methods of contraception in Turkey. However, IUD insertion may result in uterine perforation which may lead to a variety of abdominal complications or can remain asymptomatic in the abdomen for a long time without causing any complications. An asymptomatic case of a woman with an IUD inserted 42 years before is presented. To the best of our knowledge this is the longest time an IUD (found by X-ray) has been localized in the abdomen. CONCLUSION: We suggest that in asymptomatic patients with an IUD localized in the abdomen, the risks of both operating and not operating should be discussed thoroughly and in such cases, follow-up without surgery may be considered as an alternative approach.

The attitudes of menopausal women and their spouses towards menopause.

OBJECTIVE: Menopausal experience and symptom reporting of the women was reported to be affected by their attitudes to menopause which in turn is influenced by a range of variables. In this study, we primarily tried to investigate the attitudes of women and their spouses towards menopause. The other aim of the current study was to investigate the relationship between menopausal attitudes and menopausal symptom experience, depression and anxiety scores of the participants. METHOD: The sample included 60 physiological menopausal women and their spouses. Socio-demographic data were obtained with a questionnaire. The menopausal symptoms were measured through the Menopausal Rating Scale (MRS). The women and their spouses were administered the Attitudes Towards Menopause Scale (ATMS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). RESULTS: Both the menopausal women and their spouses had a positive attitude towards menopause. The women had a mean total score of 16.36 +/- 7.62 on MRS (moderate). The mean somatic, psychological and urogenital sub-scores of MRS were 6.43 +/- 3.23 (moderate), 5.97 +/- 3.33 (moderate), and 3.93 +/- 2.77 (moderate), respectively. There were no significant differences in BDI scores between the women and their spouses. However, the scores of BAI were more likely to be higher in women than their spouses (p < 0.0001). The current study revealed a significant positive correlation between MRS scores and BAI and BDI scores of the women. A significant negative correlation was found with the scores of ATMS, and scores of MRS in women. The scores of ATMS in men were significantly and negatively correlated with the total, somatic, and urogenital subscale scores of MRS in women. CONCLUSION: The main finding of this study was that both the menopausal women and their spouses had a positive attitude towards menopause. We also found that, the women who had more negative attitudes towards menopause reported more severe menopausal symptoms. Our results also demonstrated that the severity of menopausal complaints might be related to the attitudes of the husbands towards menopause.

Emergency contraception: knowledge, attitudes and practice of the pharmacy staff in Aydin, Turkey.

OBJECTIVES: This study aimed to explore the knowledge, attitudes, and practices related to emergency contraception (EC) among pharmacy staff. METHODS: This descriptive and cross-sectional survey was conducted among 143 pharmacy staff in Aydin city centre who agreed to participate. Data was collected thorough questionnaires that were filled in by face to face interviews between April and June 2007. RESULTS: Remarkably most of the participants (n = 110) did not know the action mechanism of these pills. Forty-four participants reported that these drugs caused mostly hormonal side-effects. Only four participants knew all indications of EC pills. According to 72 participants, contraceptive pills should not be available without a prescription. The number of pharmacy staff who reported giving counseling to clients about family planning methods was low (n = 12). CONCLUSIONS: The current study revealed that pharmacy staff in the region had inadequate knowledge on EC. Pharmacy staff may play a crucial role in women's access to EC, and there is a need for new interventions to improve and update their knowledge on, and to improve their attitudes toward EC methods.

The effect of low-dose combined oral contraceptive containing 100 ug levonorgestrel on plasma plasminogen activator inhibitor-1 concentrations.

OBJECTIVE: The objective of the current study was to investigate the effect of a combined oral contraceptive (COC) containing 20 ug ethinyl estradiol (EE) and 100 ug levonorgestrel (LNG) which is currently used on plasma plasminogen activator inhibitor-1 (PAI-1) concentrations. MATERIAL AND METHODS: Twenty-five women who had not used any COC for at least three months before the initiation of the study were enrolled in the control group. Twenty women who had been using COC containing 20 ug EE and 100 ug levonorgestrel LNG for at least three months prior to the study were enrolled in the LNG/EE group. Serum samples for PAI-1 and other biochemical parameters were obtained at the early follicular phase (cycle day 2-5). RESULTS: No significant difference was observed in PAl- 1 concentrations between the LNG/EE and control group (group LNG/EE: 62.4 +/- 30.2 ng/ml; control group: 58.7 +/- 26.0 ng/ml). CONCLUSION: Although we observed similar PAI-1 concentrations in both groups, there is need for further interventions to evaluate the clinical relevance of our findings.

Thrombin activatable fibrinolysis inhibitor (TAFI) is not associated with recurrent miscarriage.

AIM(S): The present study aimed to discover whether there is an association between thrombin-activatable fibrinolysis inhibitor (TAFI) antigen levels and recurrent miscarriage (RM). In particular, TAFI antigen levels of women with RM were compared with those of a control group of women with previous uncomplicated pregnancies. METHOD(S): Group 1 comprised 48 women with RM, defined as the occurrence of two or more fetal losses before 20 weeks of gestation. Group 2 (the control group) was made up of 40 women who had undergone at least two healthy pregnancies and had no history of miscarriage. Group 1 was then stratified in to two groups according to the number of pregnancy losses and group 1A (2 pregnancy losses) consisted of 22 women whereas group 1B (three or more pregnancy losses) consisted of 26 women. RESULTS: No difference was observed with regard to serum TAFI antigen levels between groups 1 and 2. There was also no statistical difference in serum TAFI antigen levels between group 1A and group 1B. CONCLUSION: The findings of the current study indicated that TAFI antigen levels are not associated with RM. Further multi-centric research with more subjects is needed to better evaluate the role of TAFI in RM.
