Objective: Although osteoporosis commonly appears among postmenopausal women, it is rarely diagnosed during the postpartum period as pregnancy-lactation associated osteoporosis (PAO). The aim of the study reported here was to investigate low bone mineral density and its associated risk factors in postpartum women., Materials and Methods: The sample consisted of 93 females aged 18-40 years and in the first month of the postpartum period. All the women had low back pain. The bone mineral density (BMD) Z-score values of the lumbar vertebrae, femur (neck and total) were examined using dual energy x-ray absorbtiometry four weeks after birth. Patients body mass index (BMI), 25-hydroxyvitaminD (25-OHD) levels and complete blood counts were recorded. Participants were divided into two groups to their Z scores: the normal group (n = 71) and the low BMD group (n = 22)., Results: The 25-OHD levels were significantly lower (p = .02) in the low BMD group [4.45 (4.0-12.4)] than in the control group [22 (12-48)], however, NLR and PLR values were similar between groups. BMI positively correlated with BMD scores for the lumbar, femoral neck and femoral overall (p = .011, p = .026 and p = .026, respectively)., Conclusion: Vitamin D deficiency and BMI may play a critical role in PAO. Low back pain during postpartum period should be carefully evaluated. Adequate calcium and vitamin D supplementation may prevent possible bone loss., (Copyright © 2019. Published by Elsevier B.V.)

Objectives: The aim of this clinical study was to evaluate the retention rate and caries-prevention effect of a flowable composite compared to a conventional resin-based sealant in a young population over a 24-month period., Methods: Thirty-four patients, ranging in age from 16 to 22 years, diagnosed with at least 2 non-cavitated pit-and-fissure caries in the first and second molars were selected for this randomized split-mouth design trial. A total of 220 sealants, were placed in 117 upper molars and 103 lower molars. The teeth were sealed with a flowable resin composite (Tetric Evo Flow) or a sealant material (Helioseal F). Each restoration was independently evaluated in terms of retention and the presence of caries at baseline and at 1, 6, 12, and 24 months. Data were analyzed using non-parametric Mann-Whitney U and Friedman 1-way ANOVA tests at p<0.05., Results: Tetric Evo Flow showed complete retention with 100%, 95.5%, 93.8%, and 88.5% at 1, 6, 12, and 24-month evaluations, respectively, while Helioseal F retention rates were 98.1%, 95.5%, 94.8%, and 85.4%, respectively, for the same evaluation periods. At the 24-month recall, 4 (4.2%) total losses were observed in subjects treated with Tetric Evo Flow and 2 total losses (2.1%) for Helioseal F, respectively. No significant differences were observed between the materials in retention rates or caries incidence for each evaluation period (p>0.05)., Conclusion: Placement of flowable composite as fissure sealants in the younger population seems to be as effective as conventional fluoride containing fissure sealants for the prevention of fissure caries., Clinical Relevance: The use of a flowable composite as a fissure sealant material, in conjunction with a total-etch, single bottle adhesive, yielded better retention than did the conventional fluoride containing resin-based fissure sealant over a 24-month period in young patients., (Copyright © 2013 Elsevier Ltd.

The aim of the study was to evaluate the extent of agreement between the findings of ultrasonography (US) and magnetic resonance imaging (MRI) in the assessment of anterior disc displacement (ADD), with or without reduction, and to assess the sensitivity, specificity and the accuracy of the US examination in establishing diagnosis. Fifty-two temporomandibular joints (TMJ) in 52 patients with chronic TMJ pain were examined by US and MRI with respect to ADD, with, and without reduction of the TMJ. The level of agreement between US and MRI findings was evaluated. The sensitivity, specificity, and the accuracy of US were found to be respectively 91%, 16% and 82% in the assessment of ADD; 70%, 38% and 57% in ADD with reduction; 50%, 89% and 76% in ADD without reduction. The findings of both methods were in agreement with each other. US method is fairly sensitive especially in detecting ADD, and it is very reliable in determining the absence of ADD without reduction. However, it was not found to be as quite effective in demonstrating ADD whether it was with or without reduction., (Copyright 2009 European Association for Cranio-Maxillo-Facial Surgery.

Background: In a single-center, double-masked, split-mouth-designed, clinical short-term trial, the authors assessed the clinical responses of teeth with dentin hypersensitivity (DH) after treating the teeth with one of three desensitizing agents across four weeks., Methods: The authors selected 131 teeth with DH in 11 participants. The authors assessed DH of the teeth by using tactile stimuli and air stimuli and had the participants record the level of sensitivity by means of a visual analog scale (VAS). The authors then treated the teeth with one of three desensitizing agents (Pain-Free [Parkell, Edgewood, N.Y.], BisBlock [Bisco, Schaumburg, Ill.], Seal & Protect [Dentsply DeTrey, Konstanz, Germany]) that they applied according to the manufacturers' instructions. The authors used a split-mouth-designed study in which the teeth in different quadrants of the participants' mouths received different desensitizing agents. The authors also conducted DH evaluations at 10 minutes after treatment and at one, two, three and four weeks. The authors analyzed data statistically by using Mann-Whitney U and Kruskal-Wallis tests., Results: The results of the statistical analysis showed that all VAS scores at the posttreatment evaluation periods were reduced significantly compared with those at baseline (P<.05). More teeth were sensitive to air stimuli than to tactile stimuli. The mean VAS scores for DH in the mandibular teeth were significantly higher than for those in maxillary teeth immediately after treatment (for tactile stimuli) and two weeks after the first application (for air stimuli) (P<.05), Conclusions: All three desensitizing agents were effective in relieving DH up to four weeks, independent of their application procedures. There was, however, a significant reduction in mean sensitivity scores of teeth that had been treated with Seal & Protect and Pain-Free compared with those of BisBlock at weeks two, three and four., Clinical Implications: The study results should be considered with caution, as it is not clear how many of the pain relief effects were related to the natural desensitization of teeth over time.

The exact incidence rate of subacute sclerosing panencephalitis (SSPE) in Turkey (and in Istanbul) is not known. We have conducted an active surveillance study to determine the epidemiological characteristics and the incidence rate of SSPE in Istanbul between the dates July 1, 2002 and July 1, 2004. We found that the incidence of SSPE in Istanbul is 2 per million. By logistic regression analysis, risk factors in SSPE development are determined as being at younger ages (OR: 1.199, 95%CI=1.047-1.372, P=0.009), living in crowded households (OR: 1.430, 95%CI=1.039-1.968, P=0.028), low education level of the mother (OR: 0.123, 95%CI=0.034-0.447, P=0.001), low household income (OR: 0.413, 95%CI=0.234-0.728, P=0.002), infant's being born out of Marmara region (Istanbul is in Marmara region of Turkey) (OR: 0.358, 95%CI: 0.172-0.746, P=0.006), infant's not being vaccinated against measles (OR: 0.495, 95%CI: 0.312-0.786), infant's having had measles before (OR: 0.235, 95%CI: 0.135-0.411). As a result, it is found in this study that SSPE is mostly related to having measles infection, and measles vaccination is found to be highly protective against SSPE. This is the first epidemiological study in SSPE from Turkey that conveys the incidence rate in Istanbul.

This study is a field study with cross-section and case control conducted in the Kucukcekmece Region of Istanbul between June 1999 and February 2000. Four hundred and ninety three dwellings selected by a simple random sampling method were visited. From a population of 2187, 58 people, after filling in a questionnaire were suspected to have epilepsy. Following an interview, neurological examination and an electroencephalogram (EEG) 17 were diagnosed as having epilepsy. Lifetime epilepsy prevalence was 0.8%. 41.2% of the 17 epilepsy cases had partial epilepsy ( n= 7), 47.0% had generalized (n = 8) and in 11.8% seizures could not be classified ( n= 2). The risk factors for epilepsy in the control group ( n= 125) from the same region and those with epilepsy were investigated by means of logistic regression analyses. Educational status (odds ratio : 1.82, 95% confidence interval : 1.13-2.94; P= 0.01), profession (OR : 0.76, 95% CI : 0.60-0.97; P= 0.03), history of epilepsy in the family (OR : 0.67, 95% CI : 0.47-0.94; P= 0.02) were determined to be correlated with epilepsy. The results have drawn attention to the fact that individuals should be informed about epilepsy.
