The purpose of our study is to determine whether bucco-palatal/lingual (BPL) root dilacerations (RD), especially in single root teeth, can be determined using the ImageJ program through only one periapical radiography. Extracted teeth without any RD ( n = 8) were determined as the control group (Group 1) and with RD in apical 1/3 part at least 20° with the longitudinal axis in the BPL direction ( n = 8) as the study group (Group 2). With the help of a simple holder system prepared, digital periapical radiographs of all teeth were taken in an anteroposterior position. Histogram analysis of all periapical radiographs was performed using the spectrum feature of ImageJ software. It was aimed to make a dilaceration analysis by comparing the groups using mean, standard deviation, minimum, maximum, and bin width values. As a result of the Mann-Whitney U test, all mean and maximum values showed a statistically significant difference between the study and control groups ( p < 0.05). This pilot study revealed that the ImageJ software can be used to diagnose BPL dilaceration in the apical 1/3 part of the root. It is important for dentists and patients that it can contribute to limiting the radiation dose to which patients will be exposed.

Recent efforts have focused on customizing orthobiologics, such as platelet-rich plasma (PRP) and bone marrow concentrate (BMC), to improve tissue repair. We hypothesized that oral losartan (a TGF-β1 blocker with anti-fibrotic properties) could decrease TGF-β1 levels in leukocyte-poor PRP (LP-PRP) and fibrocytes in BMC. Ten rabbits were randomized into two groups (N = 5/group): osteochondral defect + microfracture (control, group 1) and osteochondral defect + microfracture + losartan (losartan, group 2). For group 2, a dose of 10mg/kg/day of losartan was administrated orally for 12 weeks post-operatively. After 12 weeks, whole blood (WB) and bone marrow aspirate (BMA) samples were collected to process LP-PRP and BMC. TGF-β1 concentrations were measured in WB and LP-PRP with multiplex immunoassay. BMC cell populations were analyzed by flow cytometry with CD31, CD44, CD45, CD34, CD146 and CD90 antibodies. There was no significant difference in TGF-β1 levels between the losartan and control group in WB or LP-PRP. In BMC, the percentage of CD31+ cells (endothelial cells) in the losartan group was significantly higher than the control group (p = 0.008), while the percentage of CD45+ cells (hematopoietic cells-fibrocytes) in the losartan group was significantly lower than the control group (p = 0.03).

ABSTRACT Objectives Long-term therapy with low-dose methotrexate (MTX) is widely used in treatment of rheumatic diseases, in children. The purpose of this study was to evaluate liver elasticity in patients with juvenile idiopathic arthritis (JIA) who received MTX and compare the results with control group. Methods Liver elasticity was evaluated with shear wave elastography (SWE) technique in 25 patients aged 3–17 years who were followed up with JIA and received MTX and compared with 25 healthy controls of the same age and weight. Factors that had an effect on liver elasticity were examined. Results The mean SWE value of patients was 2.64 ± 2.13 m/s and 24.10 ± 18.50 kPa, whereas 1.83 ± 0.16 m/s and 10.09 ± 1.83 kPa in control group. There was a significant difference in liver elasticity in the patient and control groups. When the patients were evaluated as Group 1 (&lt; 1000 mg) and Group 2 (≥ 1000 mg) according to the cumulative MTX dose, no significant difference was obtained. There was positive correlation between liver elasticity and weekly MTX dose and age. Conclusions Our study revealed that liver elasticity significantly decreased in patients who received MTX when compared with the control group. The elastography technique will be understood better over time and used safely in many areas.

Purpose: To assess the effects of aprotinin on the formation and resolution of fat embolism of the lungs. Methods: The changes in arterial blood gas levels and perfusion scintigraphy were studied by forming experimental standardized fat embolism in rabbits with autogenous fat obtained from their femur medullas. Two groups, each consisting of 14 albino rabbits, were used in this study. Group 1, which received intravenous saline solution, was the control group. Group 2, which received aprotinin, was referred to as the aprotinin group. Autogenous femoral medullary content was used for embolization procedures. Arterial blood gas levels were recorded 72 hours before and 1, 24, 72 hours and 10 days following the embolization procedure. Pulmonary perfusion scintigraphies were performed 72 hours before the embolization procedure and on the first and 72nd hours, and the 10th day. Results: Fat embolism was achieved in all rabbits. Seven rabbits in the control group and one rabbit in the aprotinin group died within an hour after the embolization procedure. According to blood gas levels and perfusion scintigraphic findings, the aprotinin group significantly had less pulmonary fat embolism and recovered faster than the control group, especially during the first 24 hours. There was no significant difference in regression of pulmonary dysfunction between the two groups. Conclusion: The correlation between the blood gas levels and scintigraphic findings suggested that the administration of aprotinin for prophylactic purposes had favorable effects on the development of pulmonary gas exchange disturbance and perfusion defect in fat embolism.

Background: Evaluation of feasibility, safety and effectiveness of percutaneous nephrolithotomy (PCNL) in different age groups.Methods: Between July 1997-October 2012, 233 patients who were 65 years old and older were included in this study. These patients were divided into two age subgroups used in gerontology research. Group 1 was defined as patients 65-74 years old, Group 2 was older than 74 years old. Data from patient records, including demographic characteristics, preoperative evaluation, operative details, and complications were retrospectively analyzed and compared with control group data.Results: The mean age of 233 patients was 69.7±4.6 years. The mean operative times for Group 1, group 2 and the control group were 76.2±47.3mins, 92.9±47.6mins, 77±44mins, respectively and there was no statistically significant difference between groups 1 and 2 and the control group (p>0.05). Twenty-eight of the 233 patients (12%) needed blood transfusion due to perioperative bleeding. The transfusion rates of groups 1 and 2 were 11.3% and 16.7%, respectively. There was no statistically significant difference between the study groups and control group for blood transfusion rates (p>0.05). There was no statistically significant difference in complications between the study and control groups (p>0.05).Conclusions: In geriatric patients, stone-free rates, transfusion rates and other operation parameters are similar to younger populations when experienced surgeons perform PCNL. Despite comorbidities and decreased body reserve, PCNL can be performed without a significant increase in complications in different ages.

Objective: The objective of the present study was to determine oxidant and antioxidant status in infants with hyperbilirubinemia and/or kernicterus and to find whether there is a relationship between bilirubin level and oxidant/antioxidant status. Patients: The study includes 69 full-term newborns (neonates with hyperbilirubinemia needing phototherapy [Group 1, n = 36] and neonates with kernicterus [Group 2, n = 33]) and 25 age-matched healthy newborn. Results: Plasma total antioxidant capacity (TAC) and serum total oxidant status (TOS) were significantly higher in Groups 1 and 2 than the control group. There was a significant difference between Group 1 and control cases for malondialdehyde (MDA; p < 0.001). Total free sulfhydryl group (TTHI) values were significantly elevated in Group 1 compared to Group 2 and control cases. Correlation analysis showed that the correlation between total bilirubin (TB) and TAC, TOS, MDA and oxidative stress index may be expressed by a quadratic curve. After phototherapy, a statistically significant increase in nitrite level was observed. Conclusion: We demonstrated that the relationship between serum TB and antioxidants and oxidative stress could be expressed by a quadratic correlation curve.

Purpose: to reveal the effect of different concentrations of prepared calcium hydroxide pastes (70%, 50%, and 30%) used in regenerative endodontic on microhardness and fracture resistance of radicular dentin. Material and methods: Different concentrations of calcium hydroxide (Ca(OH)2) were prepared with measured pH, then forty eight single rooted teeth were prepared and randomized into three groups according to Ca(OH)2 paste concentrations (12 samples each) and 12 samples were availed as control group. Group I: root canal contained 30% Ca(OH)2 paste. Group II: root canal contained 50% Ca(OH)2 paste. Group III: root canal contained 70% Ca(OH)2 paste. Samples were stored at 37 0C with 100% humidity for four weeks for subsequent microhardness and fracture resistance tests. Results: There was a statistically significant reduction of microhardness  and fracture resistance between test groups and control group (P≤ 0.05), group III showed a  significant reduction  in both microhardness and fracture resistance compared to group I. However, there was no significant difference in pH between different concentration of Ca(OH)2. Conclusion: Increasing concentration of Ca(OH)2 paste can negatively affect microhardness and fracture resistance of radicular dentin in revascularization procedure.

Considering the high frequency of anaemia due to Fe deficiency, it is important to evaluate the effects of prebiotics on the absorption of Fe. The aim of the present study was to evaluate the effects of high-performance (HP) inulin, oligofructose and synergy1 during recovery from anaemia in rats through the intestinal absorption of Fe, food intake, body growth, caecal pH and weight of the intestine. Wistar rats (n 47) were fed with rations of AIN93-G with no Fe to induce Fe deficiency anaemia. At 36 d of life, anaemic rats were divided into four groups: (1) the HP inulin group; (2) the synergy1 group; and (3) the oligofructose group, all with 100 g of the respective prebiotic per kg of ration; and (4) a control group, in which the prebiotic was replaced by maize starch. Then, 25 mg of elemental Fe/kg of ration was added to all rations to allow recovery from anaemia. The final values of Hb in the HP inulin, synergy1, oligofructose and control groups were, respectively: 98 (94–99); 83 (81–92); 100 (90–114); 77 (72–81) g/l, with a statistically significant difference (P ≤ 0·001) between the oligofructose and control groups and the HP inulin and control groups. The four groups had an increase in weight and body length and had similar consumption of rations. The intestinal weight and caecal pH were significantly different between the groups that consumed prebiotics and the control group. HP inulin and oligofructose increased the intestinal absorption of Fe in rats.

Infants who sustained a spell of apnea of infancy during which they were resuscitated have been shown to be at increased risk for sudden infant death syndrome. To determine the value of the pneumogram as a predictor of outcome in this population, the first pneumogram obtained of 51 such infants was analyzed. The infants were grouped on the basis of subsequent outcome during a course of monitoring: group 1—infants who died during a subsequent event; group 2—infants who received resuscitation or vigorous stimulation to terminate a subsequent spell; group 3—infants who survived and did not have a significant subsequent episode. The results for these infants were compared with those of a control group matched for age and sex. A detailed, blinded computer analysis revealed no significant difference in the results of the pneumogram analysis between the three groups. It did not identify the infants in whom apneic spells necessitating resuscitation subsequently developed or those who died. However, when compared with the control group, infants with apnea of infancy had significantly higher mean respiratory rates, heart rates, and tachycardia indexes. It is concluded that, although the first pneumogram does not predict the risk of an adverse outcome in a population of infants with severe apnea of infancy, it does reveal subtle cardiorespiratory differences between study and control infants.
