Comparative evaluation of the success of biomaterials developed in recent years in primary molar pulpotomies

Çalışmamızın amacı; süt dişi vital amputasyon tedavilerinde; ProRoot MTA ile NeoMTA Plus'ın klinik ve radyografik başarılarının karşılaştırmalı olarak değerlendirilmesidir. Çalışmamıza yaşları 4-9 arasında değişen, toplam 60 hastada (33 kız, 27 erkek), 72 süt mandibular 2. azı dişi dahil edildi. Hastalar, kullanılacak materyale göre rastgele 2 gruba ayrıldı. Enfekte olduğu düşünülen koronal pulpanın kaldırılmasının ardından salin solüsyon ve steril pamuk peletlerle primer hemostaz sağlanarak ProRoot MTA ve NeoMTA Plus uygulandı. Tedavisi tamamlanan dişler 3, 6 ve 12. aylarda kontrollere çağırılarak klinik ve radyografik değerlendirmeleri yapıldı. Çalışmada takip süresi sonunda elde edilen verilerin istatistiksel değerlendirmeleri için, Ki-kare testi, Fisher's Exact testi, Mann-Whitney U testi ve Cochran's Q testi kullanıldı. İstatistiksel anlamlılık düzeyi p0.05). Ayrıca iki grup arasında oluşan dentin köprüsünün miktarı açısından istatistiksel olarak anlamlı fark bulunmamış (p>0.05), ancak NeoMTA Plus grubunda dentin köprüsü oluşumunun daha uzun süre devam ettiği gözlenmiştir. Çalışmamızda klinik ve radyografik değerlendirmeler ışığında; süt dişi amputasyon tedavilerinde NeoMTA Plus'ın en az diğer ProRoot MTA kadar başarılı olduğu ve NeoMTA Plus'ın avantajları göz önüne alındığında süt dişi amputasyon tedavilerinde ProRoot MTA'ya bir alternatif olarak kullanılabileceği sonucuna varılabilir.The objective of the present study is the comparative evaluation of the clinical and radiographical success of ProRoot MTA and NeoMTA Plus when used for pulpotomy in primary molars. 72 mandibular second primary molar teeth in 60 children (33 female, 27 male) aged 4-9 years with were included in the study. Patients were randomly divided into 2 groups according to the material to be used. After removing the coronal pulp, which was thought to be infected, primary hemostasis was achieved with saline solution and sterile cotton pellets, and ProRoot MTA and NeoMTA Plus were applied. Following pulpotomy treatments, patients were followed-up at 3rd, 6th and 12th months and teeth were examined clinically and radiographically. For the statistical analysis of obtained data; Chi-square test, Fisher's Exact test, Mann-Whitney U test and Cochran's Q test were used. p 0.05). In addition, no statistically significant difference was found between the two groups in terms of the amount of dentine bridge (p> 0.05), but it was observed that dentin bridge formation continued longer in the NeoMTA Plus group. In the light of clinical and radiographic evaluations in our study; it can be concluded that NeoMTA Plus is at least as successful as ProRoot MTA in pulpotomies in primary teeth and can be used as an alternative in pulpotomies in primary teeth, considering the advantages of NeoMTA Plu

Evaluation of Agreement Between Sweep Visual Evoked Potential Testing and Subjective Visual Acuity

Objectives:The primary objective of this study was to evaluate the agreement of visual acuity (VA) obtained with the sweep visual evoked potential (sVEP) method with the VA obtained with the Snellen chart. The secondary objective was to examine the effect of age and gender on agreement.Materials and Methods:Best corrected VAs of subjects were recorded with the Snellen chart, and sVEP testing was performed according to the recommendations of the International Society for Clinical Electrophysiology of Vision (ISCEV). Snellen VAs and sVEP measurements were analyzed using logMAR conversion for statistical analysis. Agreement was evaluated with Bland-Altman analysis.Results:The study included 49 subjects with a mean age of 53.5±17.3 years (range: 19-75 years) and mean Snellen VA of 0.31±0.32 logMAR (range: 1.3-0.0 logMAR). In the Bland-Altman analysis, the mean differences between the VA and sVEP measurements (VA-sVEP) were significantly different and outside the limits of agreement (p=0.035). A significant proportional bias (p=0.0007) was found in the regression analysis performed between VA-sVEP and the mean VA. According to the Bland-Altman analysis of sex subgroups, there was a significant difference between VA and sVEP measurements in female subjects (p=0.006). The difference between VA and sVEP measurement increased significantly with older age (R2: 0.306, p<0.001, β: 0.05 [0.03, 0.08]).Conclusion:In conclusion, sVEP measurements and VAs did not show statistical agreement. Cranial anatomy and endocrine differences of the subjects may affect their sVEP measurements. The difference between the methods varies according to VA level. Directly using sVEP results instead of VA would not be appropriate

A nationwide multicentre study in Turkey for establishing reference intervals of haematological parameters with novel use of a panel of whole blood

IntroductionA nationwide multicentre study was conducted to establish well-defined reference intervals (RIs) of haematological parameters for the Turkish population in consideration of sources of variation in reference values (RVs). Materials and methodsK2-EDTA whole blood samples (total of 3363) were collected from 12 laboratories. Sera were also collected for measurements of iron, UIBC, TIBC, and ferritin for use in the latent abnormal values exclusion (LAVE) method. The blood samples were analysed within 2 hours in each laboratory using Cell Dyn and Ruby (Abbott), LH780 (Beckman Coulter), or XT-2000i (Sysmex). A panel of freshly prepared blood from 40 healthy volunteers was measured in common to assess any analyser-dependent bias in the measurements. The SD ratio (SDR) based on ANOVA was used to judge the need for partitioning RVs. RIs were computed by the parametric method with/without applying the LAVE method. ResultsAnalyser-dependent bias was found for basophils (Bas), MCHC, RDW and MPV from the panel test results and thus those RIs were derived for each manufacturer. RIs were determined from all volunteers’ results for WBC, neutrophils, lymphocytes, monocytes, eosinophils, MCV, MCH and platelets. Gender-specific RIs were required for RBC, haemoglobin, haematocrit, iron, UIBC and ferritin. Region-specific RIs were required for RBC, haemoglobin, haematocrit, UIBC, and TIBC. ConclusionsWith the novel use of a freshly prepared blood panel, manufacturer-specific RIs’ were derived for Bas, Bas%, MCHC, RDW and MPV. Regional differences in RIs were observed among the 7 regions of Turkey, which may be attributed to nutritional or environmental factors, including altitude

Demographic, Clinical and Radiological Features of Healthcare Workers and Two Index Cases That Were Infected with COVID-19 (SARS-Cov-2)

To evaluate the index cases leading to the transmission of healthcare workers (HCWs) in Rize/Turkey Recep Tayyip Erdogan University Faculty of Medicine Education and Research Hospital with COVID-19 infection and the clinical features of infected HCWs. The first two COVID-19 test positive patients treated at Rize/Turkey between 10.03.2020 and 12.04.2020 and HCWs those who examined these two patients whose COVID-19 PCR test results were positive were included in this study. In Rize/Turkey, the first and second cases of positive COVID-19 which was recorded on 13.03.2020 on 25.03.2020, 27 HCWs (female, 63%, n = 17 and male, 37%, n = 10 and the mean age was 33.2 ± 6.9 years) who contacted during the treatment of these cases and became COVID-19 positive were examined. The median of symptom duration (days) of the HCWs was 5 days (range: 0–17 days). Fever, 55.6% (n = 15); malaise, 44.4% (n = 12); cough, 40.7% (n = 11); sore throat, 33.3% (n = 9); myalgia, 33.3% (n = 9); dyspnea, 14.8% (n = 4); diarrhea, 22.2% (n = 6); vomiting, 14.8% (n = 4); anosmia, 18.5% (n = 5); ageusia, 22.2% (n = 6) and headache, 37% (n = 10) of the cases. The rates of headache in female HCWs infected with COVID-19 were found to be significantly higher compared to men (52.9%). None of them had severe clinical situation requiring intensive care follow-up or acute respiratory distress syndrome (ARDS). Laboratory measurements of HCWs were carried out at the first when they had symptoms and when they recovered, and results were compared accordingly. The thorax computerized tomography (CT) findings of HCWs were normal in 74.1% (n = 20) of total. HCWs were initially affected by the COVID-19 pandemic. Early measures provided by the Health authorities, access to diagnosis and treatment, and the young age average in HCWs prevented severe outcomes such as severe clinical course and mortality at the beginning of the outbreak

Volume CXIV, Number 4, November 7, 1996

Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population.Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014.Results: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%.Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespa

Studying of the relationship between the problem solving skills of nurses and their assertiveness

Araştırma, hemşirelerin problem çözme becerileri ile atılganlıkları arasındaki ilişkinin incelenmesi amacıyla analitik- kesitsel olarak planlanmıştır. Araştırmanın evrenini 2011 yılı itibariyle ve araştırma takvimi süresince Muğla ili Muğla Üniversitesi Eğitim ve Araştırma Hastanesi'nde çalışan 300 hemşire oluşturmaktadır. Araştırma verileri, tanımlayıcı özellikleri içeren Kişisel Bilgi Formu, Rathus Atılganlık Envanteri ve Gözden Geçirilmiş Sosyal Sorun Çözme Envanteri (GGSSÇE) ile toplanmıştır. Verilerin değerlendirilmesinde, tanımlayıcı istatistikler, yüzdelik, Kruskal Wallis, Bağımsız iki örneklem T testi, Tek yönlü Varyans Analizi, Mann-Whitney-U, Pearson Korelasyon Analizi, Kolmogorov-Smirnov, Levene testi kullanılmıştır. Bekarların, çocuğu olmayanların, uzun süre şehirde yaşamış olan hemşirelerin atılganlık düzeyleri daha yüksek bulunmuştur. 40 yaş üstü hemşirelerin akılcı sorun çözme tarzı puanı, diğerlerine göre daha yüksek, servis hemşirelerinin olumsuz sorun yönelimi ve dürtüsel-dikkatsiz sorun çözme tarzı puan ortalaması daha yüksek, yönetici hemşirelerin ise toplam SPSI-R puanları daha yüksek bulunmuştur. Yine yönetimdeki hemşirelerin olumsuz sorun yöneliminin poliklinik ve klinik hemşirelerine göre daha az olduğu, poliklinik hemşirelerinin olumsuz sorun yöneliminin ise daha yüksek olduğu görülmüştür. Kadrolu hemşirelerin olumlu sorun yönelimi, akılcı sorun çözme tarzı, toplam SPSI-R puanı ve atılganlık puan ortalamalarının daha yüksek, olumsuz sorun yönelimi, kaçıngan sorun çözme tarzı ve dürtüsel dikkatsiz sorun çözme tarzı puan ortalamalarının ise daha düşük olduğu, kadrolu olmayan hemşirelerin ise kaçıngan sorun çözme tarzı puanı daha yüksek, atılganlık düzeyinin de daha düşük olduğu bulunmuştur. Hemşirelerin annesi okur yazar olmayanların toplam SPSI-R puan ortalaması daha yüksek bulunmuş, olumsuz sorun yönelimi puanı ise daha düşük bulunmuştur. Hemşirelerin RAE puanı (21,90 22,95), toplam SPSI-R puan ortalamasının (13.76 2,44), hemşirelerin sorun çözme becerilerinin ve atılganlıklarının ortalamanın üstünde olduğu bulunmuştur. Atılganlığa göre sorun çözme puan ortalamalarının istatistiksel açıdan anlamlı olduğu, atılganlık ile sorun çözmeye ilişkin tüm ölçekler arasındaki ilişkinin anlamlı olduğu bununla birlikte, en güçlü ilişkinin atılganlık ile toplam SPSI-R arasında olduğu bulunmuştur. Hemşirelerin GGSSÇE ve alt ölçekleri ile atılganlıkları ile ilişkili faktörler ise; anne eğitim durumu, çalışılan birimdeki görev, çalışılan birim, çocuk sayısı ve uzun süre yaşanılan yer olarak bulunmuştur. Bu sonuçlar doğrultusunda, atılganlık ve sorun çözmenin birlikte geliştirilmesinin her iki beceriyi de olumlu yönde etkileyeceğini düşünerek, bazı önerilerde bulunulmuştur.Research is scheduled as a cross-sectional analytical in order to study the relationship between the nurses problem solving skills with their assertiveness. Research universe constitutes 300 nurses who have worked in Muğla, Muğla University training and research hospital since 2011 and the calendar for the duration of the study. The research data was collected with the personal information form containing identifying features, Rathus Assertiveness inventory and Revised Social problem-solving inventory. In evaluating of the data, descriptive statistics, percentage, Kruskal Wallis, two independent sample T-test, one-way analysis of variance, Mann-Whitney-U, Correlation analysis, Kolmogorov-Smirnov test, Levene test were used. It is observed that singles, non-child people , having lived in the city for a long period have higher levels of assertiveness. The rational problem-solving style points of nurses over the age of 40, higher than the others, the average points of negative problem tendency and impulsive-inattentive problem solving style of service nurses were higher, but the SPSI-R scores of the total administrative nurses were higher. Still, it has been observed that the negative problem tendency of the administration nurses is less thanpolyclinic and clinical nurses, but the polyclinic nurses' negative problem tendency is higher. It has been found Staff Nurses ' positive problem orientation, rational problem-solving style, SPSI-R total score and average points of assertiveness were higher; but the negative problem tendency, avoiding problem-solving style and impulsive, reckless problem-solving style average points were lower; but the avoiding problem-solving style scores of non-resident nurses were higher, the level of assertiveness were lower. The total average score of SPSI-R of the nurses whose mother was non-literate has been found higher, but the negative problem tendency has been found lower. It has been found that the RAE score of nurses was (21.90 22,95 ), but the total average score of SPSI-R was (13.76 2,44), and problem-solving skills of nurses and their assertiveness which has been found to be above average. It has been found the averages problem solving points were statistically meaningful than assertiveness, the relation between all the scales which related to the assertiveness and the problem solving was meaningful; however, the most powerful relationship was between the total SPSI-R and the assertiveness. But it has been found nurses GGSSÇE and the factors associated with low scales with assertiveness were; mother's education, worked on the task, working unit, as a living place for a long time, and number of children. According to these results, some suggestions have been made thinking the development of assertiveness and problem solving together will affect both the development of skills with a positive, to
